[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figures 1 to 3 The present invention provides an embodiment of a locking device comprising a heat dissipation conduction box 1. Two door locks 2 are fixedly connected to the outer walls of the heat dissipation conduction box 1 on both sides, ensuring the safety and sealing of the heat dissipation conduction box 1. A door 3 is detachably connected to the front side of the heat dissipation conduction box 1 for easy maintenance and cleaning.

[0030] Multiple PCBs are detachably connected to the inner wall of the heat conduction box 1. These PCBs effectively transfer heat from the interior of the box to the external environment, thereby improving heat dissipation efficiency. Two locking devices 4 are detachably connected to either side of the PCBs. These devices securely fasten the PCBs to the inner wall of the heat conduction box 1, preventing them from loosening or falling off due to vibration or other reasons.

[0031] The locking device 4 includes a central axis 401 with a mounting slot 402 formed within it. Screws are located within the mounting slot 402 to secure the central axis 401 to the PCB. This design makes installation and removal of the locking device 4 quick and easy, while also ensuring stable securement of the PCB. A wedge 1 403 is detachably attached to the outer wall of the central axis 401. Two wedge 2s 404 are detachably attached to each end of the central axis 401. A square flat washer 405 is fixedly attached to the other end of one of the wedge 2s 404. An elastic washer 406 is fixedly attached to the other end of the square flat washer 405. A screw 407 is threadedly connected to the interior of one of the wedge 2s 404. By rotating the screw 407, the screw 407 moves toward the central axis 401, thereby squeezing the wedge 1 403 and the wedge 2 404, and then driving the wedge 1 403 to move outward, thereby achieving the reinforcement and locking of the PCB board. This structural design enables the locker 4 to achieve a good fixing effect on PCB boards of different thicknesses.

[0032] The front end of the PCB is equipped with two pullers 5. The pullers 5 include a housing 501, with a reset shaft 502 located in the middle of the housing 501. The reset shaft 502 is used to automatically reset the pullers 5 after use. A rotating shaft 503 is located at the rear end of the housing 501. The rotating shaft 503 supports the rotation of the pullers 5, thereby facilitating the removal of the PCB. The outer wall of the rotating shaft 503 is rotatably connected to the front end of the PCB. A spring 504 is fixedly connected to the interior of the housing 501. The other end of the spring 504 is fixedly connected to an insert 505. The outer wall of the insert 505 is slidably connected to the interior of the housing 501. The top of the insert 505 is removably connected to the interior of the front end of the PCB. The spring 504 provides an elastic force that allows the insert 505 to engage with the front end of the PCB without being affected by external forces, thereby securing the PCB. This design allows the pullers 5 to easily remove the PCB from the heat dissipation conduction box 1, making it convenient for users to maintain and replace the PCB.

[0033] The top of the insert block 505 is fixedly connected to a transmission block 506, the outer wall of which is slidably connected to the interior of the housing 501. A push button 507 is fixedly connected to the top of the transmission block 506, and the bottom outer wall of the push button 507 is slidably connected to the top outer wall of the housing 501. When a user pushes the push button 507, it moves, and the transmission block 506 drives the insert block 505 inward, thereby separating the insert block 505 from the front end of the PCB. This allows the user to easily control the working state of the extractor 5, thereby achieving rapid installation and removal of the PCB.

[0034] When the PCB is in use, the screw 407 is rotated and the screw 407 moves in the direction of the central axis 401, so that the wedge piece 1 403 and the wedge piece 2 404 are squeezed, thereby driving the wedge piece 1 403 to move outward, thereby achieving the reinforcement and locking of the PCB board. Then, by pressing the shell 501 of the locker 4, the inserting block 505 is aligned with the groove at the front end of the PCB board, and the spring 504 recovers its deformation to make the inserting block 505 enter the groove, thereby completing the locking; and by rotating the screw 407 in the opposite direction, the screw 407 is moved outward, so that the wedge piece 1 403 is not squeezed by external force, thereby completing the unlocking, and then pushing the push button 507, the push button 507 drives the transmission block 506 to move synchronously, thereby driving the inserting block 505 to move inward, thereby achieving the separation of the inserting block 505 from the front end of the PCB board, and then rotating the extractor 5, the entire PCB board can be taken out by pulling the extractor 5, thereby achieving the rapid disassembly and assembly of the PCB board.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
