1. Field of the Invention
The present invention relates to a press-mount device; and more particularly to a quick circuit board press-mount device capable of pressing, fixing and positioning a computer circuit board module or an interface card conveniently and quickly, and achieving an excellent operating efficiency.
2. Brief Description of the Related Art
In general, various circuit board modules and interface cards are installed onto a computer, and a press-mount device is usually provided for fixing the circuit board modules and interface cards to prevent them from being loosened for falling out when the computer is operating in an environment with vibrations or during its transportation. With reference to
Although the aforementioned prior art can press and position the interface card 110 by adjusting the height of the screw 23, yet there are still drawbacks in its operation. For example, the screw 23 is passed into the screw hole 21 of the support frame 2 from bottom to top, and sheathed to a fixing element 3 (such as a nut), so that during the assembling process, the screw 23 and the fixing element 3 may be dropped into the computer casing 1 by accident easily, which will affect the assembling efficiency. In addition, after the screw 23 is used for press-mounting the interface card 110, the portion of the screw 23 protruded out from the fixing element 3 must be cut by a cutting tool, which is a destructive operation, not only taking much effort, but also incurring a poor efficiency and danger. There is always an issue of the cutting quality, and thus such design is not good enough. Furthermore, the cut portion of the screw 23 will be dropped anywhere in the computer casing 1, and it is necessary to search and remove the cut portion, which will waste time and lower the assembling efficiency, and after the remaining end of the rotating slot 25 of the screw 23 is cut, the screw 23 cannot be used for rotating and making adjustment anymore, and cause problems when it is necessary to repair or replace the interface card 110 next time. If the interface cards 110 have different heights, the screw 23 cannot be used for the press-mounting operation or making any adjustment. As a result, it is necessary to replace the whole set of the support frame 2 and fix all interface cards 110 again, and such arrangement definitely causes tremendous inconvenience to users. Obviously, the prior art requires improvement, and it is a main subject for manufacturers and designers of the related industry to overcome the existing problems of the prior art and improving the convenience and efficiency of assembling the computers.
In view of the aforementioned problems of the conventional structural design for press-mounting a circuit board, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally developed a more efficient, convenient and space limitation-free quick circuit board press-mount device to overcome the problems of the prior art.
Therefore, it is a primary objective of the present invention to provide a quick circuit board press-mount device, capable of press-mounting a computer circuit board module, or an interface card conveniently and quickly, so as to enhance the operation of assembling computers.
Another objective of the present invention is to provide a quick circuit board press-mount device to overcome the drawbacks of the conventional circuit board being pressed and positioned with a limited spatial requirement, and requiring a limited pre-pressed height of the circuit board and different sizes of press board straps, so that the invention can achieve the effects of changing the component modules to fit the insufficient space flexibly, simplifying the assembling procedure, and saving the assembling time and labor.
To achieve the aforementioned objectives, the present invention provides a technical measure comprising: a positioning device, including a positioning board and a back board, and the positioning board having an adjusting through hole formed thereon, and a positioning screw block being disposed on a side of the adjusting through hole, an adjusting knob being pivotally installed into the adjusting through hole, and a screw rod portion being formed at the bottom of the adjusting knob, and an adjusting notch being formed on the back board, and a positioning screw hole formed on a side of the adjusting notch; an adjusting device, including a combining board, an insert board extended forward from a front end of the combining board, and the insert board having a screw hole for securing the screw rod portion, and the insert board being inserted into the adjusting notch, and the insert board having a lateral connecting board installed at a lateral side of the insert board and rotated and extended from the combining board, and the lateral connecting board having an elliptic adjusting slot for positioning the screw hole at the back board by a screw rod; and a press-mount element, coupled to the combining board.
The technical contents of the present invention will become apparent by the detailed description of the preferred embodiments together with the illustration of related drawings as follows:
The above and further objects and novel features of the invention will more fully appear from the following detailed description when the same is read in connection with the accompanying drawing. It is to be expressly understood, however, that the drawing is for purpose of illustration only and is not intended as a definition of the limits of the invention.
With reference to
The adjusting device 40 includes a combining board 41, a latching hole 411 formed separately on both sides of the combining board 41, a connecting portion 43 extended downwardly from a front end of the combining board 41, and the lateral connecting board 42 and the connecting portion 43 on both sides of the connecting portion 43 include connecting boards 431 of the combining board 41 perpendicular to each other, and each connecting boards 431 has an insert board 432 extended forwardly in a perpendicular direction. The insert board 432 includes a screw hole 433 at the center position and a lateral guide board 434 separately extended perpendicularly from both sides of the insert board 432 and corresponding to the lateral guide slot 381. The lateral connecting board 42 includes an elliptic adjusting slot 421, and the lateral connecting board 42 includes a distal protective board 422 protruded forwardly from an edge of the lateral connecting board 42. During the assembling process, the insert board 432 is inserted into the adjusting notch 38 of the back board 32, and the screw rod 44 is used to secure the adjusting slot 421 and the positioning screw hole 39, and the screw rod portion 353 of the adjusting knob 35 is screwed to the screw hole 433 of the insert board 432, such that the positioning device 30 and the adjusting device 40 are coupled to each other as shown in
The press-mount element 50 includes a press board 51 and a side board 52 extended downwardly from both sides of the press board 51, wherein a press slot 53 is formed at the center position of the press slot 53, and a latching element 54 is protruded separately from both sides of the top of the press board 51, and the latching element 54 has an elastic slot 541 formed thereon and the latching element 54 can be inserted into the latching hole 411 of the combining board 41, such that the press-mount element 50 is positioned at the bottom of the rear side of the combining board 41.
With reference to
When the quick circuit board press-mount device of the present invention is assembled to the casing 300, its operating surface is at the top of the casing 300, and the height of the press-mount element 50 is adjusted simply by using a screwing tool 200 to rotate the adjusting knob 35 with respect to the operating hole 301 at the top of the casing 300, so that the screws will not be dropped into the casing 300, and the circuit board module and interface cards can be press-mounted very conveniently and quickly, so as to enhance the efficiency of assembling the computers.
