[0037] In the following description, specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0038] Please refer toFigures 1 to 4 , Figure 1 is an exploded view of a board self-locking assist plugging device provided by a specific embodiment of the present application; Figure 2 is a schematic structural diagram of a board self-locking assist plugging device provided by a specific embodiment of the present application when in a clamped state; Figure 3 is a schematic structural diagram of a board self-locking assist plugging device provided by a specific embodiment of the present application when in a released state; Figure 4 is a schematic structural diagram of a pressure plate of a board self-locking assist plugging device provided by a specific embodiment of the present application.

[0039] A specific embodiment of the present application provides a board self-locking assist plugging device, including: a first vertical plate 1, a second vertical plate 22, a board fixing plate 3 and a pressure plate 4. The upper end of the first vertical plate 1 is provided with a first vertical plate extension 11 extending horizontally. The second vertical plate 22 is arranged parallel to the first vertical plate 1. The board fixing plate 3 is vertically arranged between the first vertical plate 1 and the second vertical plate 22 for carrying a board 5. The board 5 can be fixed to the board fixing plate 3 by screws or other fastening means to improve the structural strength during the insertion and extraction of the board 5. The pressure plate 4 is hinged to the upper end of the board fixing plate 3, that is, the pressure plate 4, the board fixing plate 3 and the board 5 form an integral body. One end of the pressure plate 4 is provided with a buckle 41, and the other end is used for detachably connecting to the upper end of the second vertical plate 22. When the board fixing plate 3 and the pressure plate 4 carry the board 5 downwards to insert the board 5 into the slot, the buckle 41 is snapped into the first vertical plate extension 11, and at the same time, the other end of the pressure plate 4 is fixedly connected to the upper end of the second vertical plate 22 relatively. When it is necessary to take out the board 5 from the slot, first disconnect the connection between the pressure plate 4 and the upper end of the second vertical plate 22, and then rotate the pressure plate 4 upwards. The pressure plate 4 can be supported by the first vertical plate extension 11, so that the side of the board 5 close to the first vertical plate 1 is first lifted upwards, and then the integral body of the pressure plate 4, the board fixing plate 3 and the board 5 can be easily pulled out upwards. When the pressure plate 4 rotates upwards relative to the board fixing plate 3, it can play a lifting role on the board fixing plate 3. Compared with the traditional board 5 insertion structure, the plugging device of the present application can play a boosting role on the board 5 when inserting the board 5, and can quickly pull out the board 5 by means of the reaction force of the first slot 11 on the first vertical plate 1 when pulling out the board 5. Moreover, when inserting the board 5, there is no need to contact the board 5, so the structure and components of the board 5 can be avoided from being damaged. In addition, the board self-locking assist plugging device of the present application does not provide a clamping structure on the side of the board 5 itself, that is, there is no clamping relationship between the plugging device and the board 5, but the board 5 is limited between the first vertical plate 1 and the second vertical plate 22 through the connection between the pressure plate 4 and the first vertical plate 1 and the second vertical plate 22. It should be noted that the board self-locking assist plugging device can be applicable to the server board 5, and can also meet the disassembly and assembly requirements of the boards 5 of various communication, storage and other devices.

[0040] In some embodiments, a catch 61 is further included. The catch 61 is slidably connected to the pressing plate 4. The upper end of the second vertical plate 22 is provided with a laterally extending second card slot 22. When the catch 61 is moved to be caught in the second card slot 22, the clamping connection between the pressing plate 4 and the second vertical plate 22 can be realized; when the catch 61 is moved in the reverse direction to move the catch 61 out of the second card slot 22, the unlocking between the pressing plate 4 and the second vertical plate 22 can be realized. It should be noted that the matching structure of the above-mentioned catch 61 and the second card slot 22 belongs to one type of clamping connection. In addition, other clamping connection methods can also be selected, and the present embodiment does not make specific limitations on this. In addition to the clamping connection, a screw can also be used for detachable connection. In order to avoid the use of tools, the screw is preferably a hand-tightening screw, and the pressing plate 4 and the second vertical plate 22 are provided with connection holes for the screw to pass through.

[0041] In some embodiments, an elastic member 64 is further included. The elastic member 64 can be connected to the pressing plate 4. The elastic member 64 is used to press the catch 61 against the second card slot 22, that is, the clamping stability between the catch 61 and the second card slot 22 can be improved through the elastic member 64, and the elastic member 64 can be a spring or a spring washer, etc.

[0042] Further, a slider 6 is further included. The catch 61 is arranged at one end of the slider 6; a sliding groove 43 is arranged on the pressing plate 4, and a through hole is arranged on one side of the sliding groove 43. The slider 6 is slidably connected in the sliding groove 43, and the catch 61 extends out of the sliding groove 43 from the through hole. The two ends of the elastic member 64 are respectively pressed against the slider 6 and the pressing plate 4. As Figure 1 shown, the catch 61 is arranged at the right end of the slider 6, the sliding groove 43 is arranged at the upper right end of the pressing plate 4, a through hole is arranged on the right side wall of the sliding groove 43, the size of the slider 6 is larger than that of the through hole, and the size of the catch 61 is not larger than that of the through hole, so that the right side wall of the sliding groove 43 plays a limiting role on the slider 6. Among them, the sliding groove 43 can improve the smoothness of the movement of the slider 6. The connection positions of the elastic member 64 with the slider 6 and the pressing plate 4 can be selected according to actual needs, as long as it can ensure that the elastic member 64 can press the catch 61 against the second card slot 22.

[0043] In order to further improve the smoothness of the movement of the slider 6 in the sliding groove 43, a guide pin 45 is arranged on the side wall of the end of the sliding groove 43 far from the through hole, and a guide groove 63 slidably connected to the guide pin 45 is arranged at the end of the slider 6 far from the catch 61. That is, the mutual cooperation of the guide pin 45 and the guide groove 63 can play a limiting role on the slider 6 to prevent the slider 6 from moving out of the sliding groove 43. As Figure 1 shown, pin holes for connecting the guide pin 45 are respectively arranged on the front and rear sides of the left end of the sliding groove 43, and guide grooves 63 extending along its moving direction are respectively arranged on the front and rear sides of the left end of the slider 6. When the slider 6 moves to the right, the guide groove 63 can play a right limiting role on the slider 6; when the slider 6 moves to the left, the guide groove 63 can play a left limiting role on the slider 6.

[0044] Furthermore, a limiting plate 44 is provided in the sliding groove 43. A chamber with a downward opening is provided at the bottom of one end of the slider 6 near the hook 61. The limiting plate 44 is located in the chamber. One end of the elastic member 64 abuts against the side of the chamber near the hook 61, and the other end abuts against the limiting plate 44. As Figure 1 shown, the left end of the elastic member 64 abuts against the right end of the limiting plate 44, and the left end of the elastic member 64 abuts against the right side wall of the chamber. A connecting column for sleeving the elastic member 64 can be provided on the right side of the limiting plate 44 to improve the smoothness of the expansion and contraction of the elastic member 64.

[0045] To facilitate the user to push the slider 6, a groove 62 is provided in the middle of the upper end of the slider 6. As Figure 1 shown, anti-slip patterns are provided on the left side of the upper end of the slider 6. The convenience of pushing the slider 6 can be improved through the structure of the groove 62 and the anti-slip patterns. An arrow pointing to the left is provided on the left part of the upper surface of the slider 6 to play a role of marking, and at the same time, the arrow can also play the role of an anti-slip pattern.

[0046] In some embodiments, the first vertical plate 11 is a square groove, and the lower surface of the buckle 41 is an inclined surface 411 that contacts the groove bottom surface of the square groove. As Figure 1 and Figure 4 shown, when the pressing plate 4 is pressed down, through the inclined surface 411 on the lower surface of the buckle 41, it is convenient for the buckle 41 to be snapped into the square groove. When the left end of the pressing plate 4 rotates upward around its joint with the board card fixing plate 3, through the inclined surface 411 on the lower surface of the buckle 41, it is convenient for the right end of the buckle 41 to move upward relative to the first vertical plate 11.

[0047] In some embodiments, an opening groove 42 is provided at one end of the pressing plate 4 away from its detachable connection with the second vertical plate 22. The groove length direction of the opening groove 42 extends along the length direction of the pressing plate 4. As Figure 4 shown, the left end of the pressing plate 4 is a bifurcated structure, and a buckle 41 and a shaft hole are respectively provided at the ends of the two bifurcations. The shaft hole is used for the hinge connection between the pressing plate 4 and the board card fixing plate 3. Through the bifurcated pressing plate 4, the convenience of its hinge connection with the board card fixing plate 3 can be improved, and the purpose of light weight can also be achieved.

[0048] In some embodiments, a flap 31 is provided on one side of the board fixing plate 3 close to the first vertical plate 1. One end of the pressing plate 4 close to the buckle 41 is hinged to the upper end of the flap 31. Specifically, a hinge support can be provided at the upper end of the flap 31. Specifically, the opening groove 42 of the pressing plate 4 is stuck on the front and rear sides of the hinge support, and then the pressing plate 4 can be hinged to the board fixing plate 3 by passing the hinge shaft 32 through the shaft hole and the hinge support. The material of the hinge shaft 32 can be metal or plastic. In addition, the materials of the pressing plate 4 and the hook 61 are preferably plastic. Two buckles 41 are respectively arranged at the ends of the two branch ends of the pressing plate 4. Correspondingly, two first clamping grooves 11 corresponding to the two buckles 41 one by one are provided on the first vertical plate.
