The present invention relates to a mainboard of an electronic device, and more particularly to a mainboard withdrawing structure.
In general, an electronic device relies on a mainboard to carry out operations of different functions. The mainboard is plugged into a slot according to the requirement of use. For example, the mainboard or a display interface card of an industrial computer is mounted and installed onto a computer motherboard. In order to function correctly, the mainboard must be inserted into the slot tightly and securely to prevent it from falling off. The convenience and easiness of pulling out the mainboard are usually not taken into consideration, and thus it is quite troublesome for operators to pull out the mainboard from the slot.
During a quality inspection process of the manufactured mainboards, the mainboards are plugged into the respective slots one by one, and then the plugged mainboards are replaced by some other mainboards right after the inspection, and thus the mainboards have to be pulled out from the slots frequently. However, a general mainboard usually does not have the design of a structure for pulling out the mainboard easily, so that an operator often needs to hold a heat sink 71 of the mainboard 7 by a hand as shown in
In view of the aforementioned problems, it is a main subject of this invention to provide a feasible solution to overcome the difficulty of withdrawing the mainboard.
Therefore, it is a primary objective of the present invention to provide a mainboard withdrawing structure for electronic devices, and the structure can be used to pull out a mainboard from a slot easily and effortlessly, thus not just providing a convenient operation only, but also preventing damages to the mainboard.
To achieve the aforementioned and other objectives, the present invention discloses a labor-saving mainboard withdrawing structure for electronic devices, configured to be corresponsive to a slot, and provided for withdrawing a mainboard out from the slot in a withdrawing direction, characterized in that the withdrawing structure comprises: a fixed seat; two movable seats, installed on both sides of the fixed seat, and limited to move in the withdrawing direction only, and having a space defined between the two movable seats for installing the mainboard, a rail track formed on an opposite side and extending along the withdrawing direction for slidably inserting the mainboard, and the two movable seats having a pushing portion separately for abutting against the mainboard; and two pushing members, pivoted at one of the movable seats corresponsively, and each pushing member having a head provided for operators to push and a tail abutting against the fixed seat, and a through hole being formed on the fixed seat and configured to be corresponsive to each respective pushing member, and the tail of each pushing member passing and extending into the corresponding through hole, and each head being pushed to pivot each tail, and each tail abuts against a front side of the corresponding through hole, and each movable seat being pushed in a retreat distance along the withdrawing direction relative to the fixed seat when each movable seat is pivoted at each tail, so as to detach the mainboard from the slot by pushing each pushing portion.
Preferably, the retreat distance is greater than the depth of inserting the mainboard into the slot, so that the mainboard can be separated completely from the slot when the movable seat is moved.
Preferably, each pushing member has a corresponding positioning hole formed between the head and the tail, and a positioning member is passed through the positioning hole to position each pushing member onto the movable seat.
Each positioning member comprises a threaded section, a middle section and a cap integrally and sequentially coupled to each other, and the middle section has an outer diameter falling within a range between the outer diameter of the threaded section and the outer diameter of the cap, and the threaded section is locked into a screw hole of the movable seat, and the middle section is passed into the corresponding positioning hole.
Preferably, the tail of each pushing member abutting against a side with the corresponding through hole is in an arc shape.
The fixed seat has at least one long hole configured to be corresponsive to the two movable seats and extending along the withdrawing direction, and the movable seat has a limit member configured to be corresponsive to the long hole and passed through the long hole, so that the movable seat is limited by the limit member to move within the range of the long hole only.
Preferably, each long hole has a length greater than the depth of inserting the mainboard into the slot, so that the mainboard can be separated completely from the slot when the movable seat is moved.
Each limit member comprises a threaded section, a middle section and a cap integrally and sequentially coupled to each other, and the middle section has an outer diameter falling within a range between the outer diameter of the threaded section and the outer diameter of the cap, and the threaded section is locked into a screw hole of the movable seat, and the middle section is passed into the long hole.
In summation of the description above, the present invention can make the withdrawal of the mainboard easier and more effort-saving without causing too much physical burden, so as to improve the efficiency of the mainboard testing. In addition, the invention also can ensure a correct withdraw of the mainboard to protect the product from damage or failure.
The above and other objects, features and advantages of this disclosure will become apparent from the following detailed description of the specification together with the illustration of the accompanying drawings.
1: Fixed seat; 11: long hole; 12: Limit member; 13: Through hole; 131: Front side; 2: Movable seat; 21: Space: 22: Rail track; 23: Pushing portion; 24: Screw hole; 25: Screw hole; 3: Pushing member; 31: Head; 32: Tail; 33: Positioning hole; 34: Positioning member; 41: Threaded section; 42: Middle section; 43: Cap; 5: Slot; D: Withdrawing direction; and 6: Mainboard.
With reference to
The fixed seat 1 comprises a wide board, a movable seat 2 disposed on both sides of the fixed seat 1, a space 21 defined between the two movable seats 2 for installing a mainboard. The two movable seats 2 have a rail track 22 formed on an opposite side and extending along the withdrawing direction D for slidably inserting the mainboard, so as to limit and guide the movement of the mainboard. A pushing portion 23 outwardly extends from an end of each movable seat 2 adjacent to the slot 5 towards the space 21, and each pushing portion 23 abuts against the mainboard to control its movement. In this embodiment, the slot 5 includes but not limited to a PCI slot or a PCIE slot.
The fixed seat 1 has two long holes 11 configured to be corresponsive to each movable seat 2 and extending along the withdrawing direction D, and at least one limit member 12 passing through the long hole 11 and locked to the movable seat 2, so that each movable seat 2 is limited by the limit member 12 to move within the range of the long hole 11 only. In other words, each movable seat 2 can move in the withdrawing direction D only. In this embodiment, the length of each long hole 11 is greater than the depth of inserting the mainboard into the slot 5.
Each of the limit members 12 is a screw as shown in
Each movable seat 2 comes with a pushing member 3 configured to be corresponsive to each other. Each pushing member 3 comprises a head 31 and a tail 32, and a positioning hole 33 is formed between the head 31 and the tail 32, and a positioning member 34 is passed through the corresponding positioning hole 33 to position the corresponding pushing member 3 on the corresponding movable seat 2. Each positioning member 34 is a screw as shown in
The fixed seat 1 has a through hole 13 formed thereon and configured to be corresponsive to the two pushing members 3, and the tail 32 of each pushing member 3 is passed and extended into the corresponding through hole 13, so that when the head 31 is pushed to rotate downward, the tail 32 will pivot towards the fixed seat 1 accordingly. Since the corresponding movable seat 2 can be moved relative to the fixed seat 1, therefore when each movable seat 2 is pivoted at the tail 32, each tail 32 will abut against a front side 131 of the corresponding through hole 13, and the front side 131 of the through hole 13 remains unmoved, so that the tail 32 will retreat, and each movable seat 2 will be pushed to a retreat distance along the withdrawing direction D relative to the fixed seat 1. In this embodiment, the tail 32 abutting against a side of the corresponding through hole 13 is in an arc shape to facilitate pushing the corresponding movable seat 2. In addition, the retreat distance of each movable seat 2 is greater than the depth of inserting the mainboard into the slot 5.
With the structure as shown in
In this embodiment, the corresponding movable seat 2 is pushed by each pushing member 3 to produce the retreat distance, and the length of each long hole 11 formed on the fixed seat 1 is greater than mainboard 6 the depth of inserting into the slot 5, so that when the mainboard 6 is retreated synchronously with the movable seats 2, the mainboard 6 can be separated from the slot 5 completely, and the mainboard 6 can be pulled out easily.
In summation of the description above, the present invention can make the withdrawal of the mainboard easier and more effort-saving without causing too much physical burden, so as to improve the efficiency of the mainboard testing. In addition, the invention also can ensure a correct withdraw of the mainboard to protect the product from damage or failure.
