The present invention relates to a guiding device and a display device, and more particularly, to a guiding device and a self-unloading anti-separation display device.
The existing display screen usually includes a display screen frame and a display screen installed in the display screen frame, wherein a signal connector of the display screen is connected to a signal interface on the display screen frame. Since the connection between the signal connector of the display screen and the signal interface on the display screen frame has certain tightness, and both the frame and the display screen are provided with a magnet, and the two are adsorbed by the magnets, so that the display screen and the frame are tightly installed. Therefore, when a display module needs to be unloaded from a display screen box, the display screen needs to be adsorbed by a magnetic auxiliary screen disassembly tool, so as to disassemble the display screen by offsetting the magnet adsorption force between the display screen and the frame. However, this situation is prone to have the problem that the lamp beads of the display screen are damaged by the magnetic auxiliary screen disassembling tool; moreover, on one hand, the magnetic auxiliary screen disassembling tool has a heavier weight, after the screen is disassembled, the magnetic auxiliary screen disassembling tool is possible to fall off, and on the other hand, after the display screen is disassembled from the frame, the display screen cannot be left on the frame and needs to be immediately supported. When an operator needs to perform an operation check on a plurality of screens, each screen needs to be disassembled from the frame firstly, and the display screen cannot be left on the frame if the display screen is separated from the frame. If the display screen is mistakenly disassembled, the display screen also needs to be disassembled and then is installed again. Therefore, it is easy to increase the operator's work intensity.

The present invention further relates to a self-unloading anti-separation display device comprising the guiding device according to any one of the guiding devices above, wherein the self-unloading anti-separation display device comprises a display screen and a frame, the display screen is a first component, the frame is a second component, the display screen and the frame are cooperatively installed, a cooperative installation surface of the first component is provided with an unloading device of a guiding device, the display screen is provided with a guidepost, and the frame is provided with a guide hole.
The present invention further relates to a self-unloading anti-separation display device comprising the guiding device according to any one of the guiding devices above, wherein the self-unloading anti-separation display device comprises a display screen and a frame, the frame is a first component, the display screen is a second component, the frame and the display screen are cooperatively installed, a cooperative installation surface of the first component is provided with an unloading device of a guiding device, the frame is provided with a guidepost, and the display screen is provided with a guide hole.
The present invention has the beneficial effects that: by arranging the guiding device on the cooperative installation surface of the first component and starting the driving device of the unloading device by a control device, the driving device drives the linkage between the first transmission piece and the pushing mechanism, the pushing mechanism drives the first dowel bar on the second transmission piece to move, the first dowel bar drives the second dowel bar to move, and the second dowel bar abuts with the second component or abuts with the abutting end on the second component, so that the first component is displaced relative to the second component, thus forming a gap between the first component and the second component. When the operator separates the first component from the second component, since at least one guidepost is arranged in the cooperative installation surface of the first component, and at least one guide hole is arranged at the position of the cooperative installation surface of the second component corresponding to the guidepost, the guidepost is inserted into the guide hole, and when the pushing mechanism applies a reaction force to the second component, the guidepost moves along the guide hole.
Therefore, the first component cannot be completely separated from the second component while the pushing mechanism generates a gap between the first component and the second component, but the guidepost is inserted into the guide hole to support the first component or the second component. When the first component is the display screen and the second component is the frame, the guidepost is arranged in the display screen, and the guide hole is arranged in the frame; when the first component (display screen) is pulled, at the moment, the guidepost will slide along the guide hole until the guidepost is completely separated from the second component, then the display screen is separated from the frame.
Similarly, when the first component is the frame and the second component is the display screen, the guidepost position is arranged in the frame, and the guide hole is arranged in the display screen; when the second component (display screen) is pulled, at the moment, the guidepost will slide along the guide hole until the guide hole is completely separated from the first component. Therefore, when the display screen needs to be replaced, and dismantled for maintenance or changing the installation position thereof, the guiding device can assist in supporting the display screen already separated by the unloading device on the frame, and generate a gap between the display screen and the frame. Therefore, when the display screen is disassembled, the operator is not necessary to disassemble the display screen from the frame completely; multiple display screens can be separated at the same time and then checked one by one, if replacement is not necessary, the display screen does not need to be disassembled from the frame completely, and can be directly pushing back to the original position.
Even if the screen is completely disassembled, the screen is ejected out by the pushing mechanism, the display screen is supported on the frame by a guide bar, and the display screen can be disassembled by pulling. It is not necessary to use a strong magnetic screen disassembly device in the entire process, thus reducing the damage of the strong magnetic screen disassembly device to the LED lamp beads on a display panel during adsorption, reducing the working intensity, and improving the working efficiency.
In addition, when placing the display screen, the display screen can be supported by the guidepost which generates a gap between the display screen and a placement plane. Therefore, when the display screen is taken again, the gap is more convenient to manually pick up the display screen, and the gap also avoids the back of the display screen from directly contacting with the ground, thus reducing the wear on the back of the display screen, and reducing blot generated on the back of the display screen.
The present invention has a simple overall structure, is easy to produce and manufacture, has low cost, is easy to use, has strong adaptability, and saves time and labor.
These and other aspects will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings in which:
The embodiments of the present invention will be described in detail hereinafter, the examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout the drawings denote the same or similar elements or the elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but cannot be construed as limiting the present invention.

Further, the guidepost 60 is arranged at each angular position of the first component, and the guidepost 60 is vertically arranged relative to the cooperative installation surface 103 of the first component. Of course, other angles between the guidepost 60 and the cooperative installation surface 103 of the first component can also be formed, which is not limited herein. The guidepost 60 is vertically arranged relative to the cooperative installation surface 103 of the first component, so that after the display screen is separated from the frame, the display screen can be conveniently removed from the frame when the operator takes away the display screen, which is also convenient for the operator to observe the state of the display screen after separating from the frame.
Further, the guidepost 60 is a buffer such as an air-pressure rod, a hydraulic pressure rod, or an air spring, a fixed end of the guidepost 60 being a buffer such as an air-pressure rod, a hydraulic pressure rod, or an air spring is fixedly installed with the display screen or the frame, and since the other end of the guidepost 60 being a buffer such as an air-pressure rod, a hydraulic pressure rod, or an air spring is a movable end, the guidepost 60 can be retracted. Therefore, the end is arranged towards the guide hole 70, after the display screen and the frame are assembled, the movable end is located in the guide hole 70, through a pushing effect of the unloading device, when the first component 10 is separated from the second component 20 by the unloading device 30, since the guidepost 60 has an elastic force, the guidepost 60 will give a counter elastic force to the first component 10 to pop from the second component 20 at the moment when the first component 10 is separated from the second component 20, or the guidepost 60 will give a counter elastic force to the second component 20 to pop from the first component 10, so as to further increase the separation force of the first component 10 or the second component 20, so that the first component 10 or the second component 20 can be conveniently and automatically disassembled, thus reducing the occurrence of the failed disassembly.
Further, the guidepost 60 is entirely an elongated cylinder, which facilitates better processing and installation, and can also be convenient to increase the sliding distance of the first component 10 on the second component 20 or the sliding distance of the second component 20 on the first component 10, thus avoiding the problem that the first component 10 or the second component 20 falls off directly. Certainly, the guidepost 60 can also be an elongated cylinder having square cross-section, or an elongated cylinder having elliptical cross-section, and certainly, the cross-section shape of the guidepost 60 is not limited to the various shapes above.
The pushing mechanism 50 is connected to the driving device 40 in a transmission way, the pushing mechanism 50 has at least one set of telescopic dowel bars 501, an end part of the dowel bar 501 is an inclined surface 502, and a small end formed by the inclined surface 502 is arranged close to the cooperative installation surface 103 of the first component; and the driving device 40 drives the dowel bar 501 to move along the cooperative installation surface 103 of the first component, when the dowel bar 501 moves towards the second component 20, the inclined surface 502 of the dowel bar 501 abuts with and moves along the second component 20, so as to separate the first component 10 from the second component 20.
By applying the technical solution of the embodiment of the present invention, the driving device 40 and the pushing mechanism 50 are arranged on the cooperative installation surface 103 of the first component to perform linkage, so as to enable the pushing mechanism 50 to move along the first component 10, so that the pushing mechanism 50 can press the second component 20 by the inclined surface 502, the inclined surface 502 slides on the second component 20 to gradually separate the first component 10 from the second component 20, so as to create a gap therebetween, and the first component 10 is separated from the magnetic adsorption of the second component 20, so as to facilitate the disassembly of the first component 10.
Further, referring to
Referring to
Further, the driving device 40 is a cylinder; the first transmission piece 401 is a gear rack connected to the driving device 40 in a transmission way, and the surface thereof has gear teeth; the second transmission piece 402 is a gear meshed with the gear rack, so that the gear rack is connected to the gear in a gear rack way; an axis of the gear is provided with the first dowel bar 5011; the first dowel bar 5011 is a short shaft arranged on the axis of the gear; and the second dowel bar 5012 is a bar body having a connecting hole 5013 at the end part, and the connecting hole 5013 is spirally sleeved with the short shaft.
The first transmission piece 401 can be the output shaft rotatably connected to the driving device 40, the driving device 40 can drive the output shaft to rotate, and when the driving device 40 is the motor, the first transmission piece 401 can directly be the output shaft of the motor. When the driving device 40 is the cylinder, the output shaft can be the gear rack connected to an output end of the cylinder, the gear rack is meshed with the gear, and when the cylinder is linked with the gear rack, the gear rack drives the gear to rotate, so as to drive the first dowel bar 5011 to rotate, which certainly can be other power components.
Further, two sets of the first dowel bars 5011 are symmetrically arranged along the axis relative to the second transmission piece 402, thus forming a double-screw rod connection.
In order to facilitate the production and manufacturing, the first transmission piece 401 is connected to the second transmission piece 402 in a worm and gear way, the short shaft can be integrally formed with the gear, two short shafts are preferably arranged at two end surfaces of the gear respectively, and certainly, one short shaft is also available. When two short shafts are provided, the pushing force is more balanced on the second component 20, and the first component 10 can be effectively separated from the second component 20.
Referring to
Further, the clamping groove 5016 is connected to the clamping head 5017 in a joggled joint way, which enables the assembly and disassembly to be easier and faster.
In practical application, the separation distance between the first component 10 and the second component 20 is actually greater than or equal to the thickness of the second dowel bar 5012 vertical to the direction of the first component 10. Therefore, a size and a thickness of the second dowel bar 5012 can be set according to different usage conditions, and the separation dimension between the first component 10 and the second component 20 is adjusted. Therefore, the second dowel bar 5012 is configured as detachable shaft sleeve 5014 and pushing rod 5015, the shaft sleeve 5014 is disassembly clamped with the pushing rod 5015, so as to facilitate the replacement of the pushing rod 5015 with different size to meet different pushing distances.
Referring to
Further, the inclined surface 502 has at least two sub-inclined surfaces 502 with different angles, the sub-inclined surfaces 502 are connected to each other, and a slop of the sub-inclined surface 502 arranged closer to the cooperative installation surface 103 of the first component is smaller than a slope of the sub-inclined surface 502 arranged farther away from the cooperative installation surface 103 of the first component.
In this way, when the dowel bar 501 is pushed and the inclined surface 502 abuts with a abutting end 301, different sliding speeds will be generated in sliding, the sub-inclined surface 502 of the abutting end 301 with a smaller slope has slower speed during the sliding process, and the sub-inclined surface 502 of the abutting end 301 with a larger slope has faster speed in the sliding process. Since a larger pushing force is required to separate the second component 20 from the first component 10 at the initial stage of starting the motor, and since the smaller the degree is, the slower the pushing speed is, and the larger the force is, the motor can separate the first component 10 from the second component 20 by larger force, so that the output force of the motor can be used efficiently. Since the second component 20 is not attracted by the magnet after separating from the first component 10, and too strong force is not required, the degree of the sub-inclined surface 502 arranged far from the cooperative installation surface 103 of the first component is increased, and the motor can output relatively minor force to complete the screen disassembly action, so that the pushing force produced by the output force of the motor is released more uniformly and effectively.
Referring to
Further, a guiding groove 101 for positioning the second dowel bar 5012 is arranged at an installation position of the second dowel bar 5012 in the first component 10, so that the second dowel bar 5012 is stuck inside the guiding groove 101 and moves along the guiding groove 101.
In this way, the storage and installation of the second dowel bar 5012 can be facilitated, and the entire second dowel bar 5012 can be prevented from protruding too much from the cooperative installation surface 103 of the first component, thus resulting in problems of ugly appearance and incontinent use and storage.
Further, the guiding groove 101 is a straight groove, the second dowel bar 5012 is a straight bar, a plurality of positioning bars 102 for positioning the straight bar are spanned on an opening of the straight groove by intervals, and the positioning bar 102 is arranged vertical to the extension direction of the straight bar.
In practical use, the second dowel bar 5012 is positioned by the positioning bar 102, and the positioning bar 102 is an integrally formed structure on the first component 10, which can reduce the processing procedure and processing complexity of the guiding groove 101, can form integrally in manufacturing of the first component 10, and prevents the second dowel bar 5012 from falling off from the first component 10. Therefore, considering the structural strength and depanning convenience, the installation structure of the second dowel bar 5012 is the preferred form.
Further, the guiding groove 101 is connected to the second dowel bar 5012 by a T-shaped ring groove structure.
In this way, the second dowel bar 5012 can be effectively positioned on the cooperative installation surface 103 of the first component, and the T-shaped ring groove can facilitate the clamping, disassembly and processing between the second dowel bar 5012 and the guiding groove 101.
Further, the guiding groove 101 is a Y-shaped groove, which has at least two branches, and the second dowel bar 5012 is a Y-shaped bar matched with the guiding groove 101.
Referring to
The driving device 40 and the pushing mechanism 50 can be arranged at any position on the back of the first component 10, and can be arranged in multiple sets, when the first transmission piece 401 rotates, the second transmission piece 402 can be driven to rotate, thereby driving the first dowel bar 5011 to rotate, and when the first dowel bar 5011 rotates, the second dowel bar 5012 is driven to moves linearly. When the shape of the first component 10 is not limited to a rectangular screen, the second dowel bar 5012 is branched into a plurality of branch rods to facilitate the use of the first component 10 with irregular edges separated from the second component 20, when the first component 10 is in other shapes, such as a circle or a triangle, etc., the guiding groove 101 is provided with other branch grooves, and the second dowel bar 5012 is provided with other branch rods so as to abut with other points on the 20, which facilitates the first component 10 to be separated from the second component 20.
Further, the cooperative installation surface of the second component is provided with at least one abutting end. In different situations, a plurality of the unloading devices 30 can be arranged, the quantities of the abutting end 301 and the unloading device 30 are the same, or the quantity of the abutting end 301 is at least twice the quantity of the unloading device 30. Specifically, a second dowel bar 5012 provided with an inclined surface is corresponding to an abutting end 301.
Further, the abutting end 301 of the second component 20 is arranged in a raised manner, so as to facilitate the application of force to the second component 20 by the inclined surface 502 of the second dowel bar 5012.
Referring to
Further, the contact surface between the abutting end 301 and the inclined surface 502 is also arranged inclinedly. In order to successfully generate the relative sliding when the inclined surface 502 is contacted with the abutting end 301 and enable the second dowel bar 5012 to slide more smoothly, an inclined shape is also available, and the contact surface between the abutting end and the inclined surface can also be a transitional arc surface with a certain slope.
