[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-2The utility model provides an embodiment: a PCB circuit board for convenient positioning, including a PCB board 1, positioning components are arranged around the top of the PCB board 1, the positioning component includes a mounting seat 2, the bottom of the mounting seat 2 is fixedly connected to the top of the PCB board 1, a damping rod 3 is fixedly connected inside the mounting seat 2, one end of the damping rod 3 is fixedly connected to a lever 5, a side of the lever 5 away from the damping rod 3 is fixedly connected to a connecting rod 6, a spring 4 is sleeved inside the damping rod 3, and one end of the connecting rod 6 away from the lever 5 is fixedly connected to a positioning block 7, buffer components are arranged on the front and back sides of the bottom of the PCB board 1, a slide groove is opened inside the mounting seat 2, and the lever 5 is specifically slidably connected in the slide groove.

[0031] Specifically, the PCB board 1 is the main body of the circuit board, the mounting seat 2 is used to facilitate the accommodation of the internal structure, the damping rod 3 and the spring 4 are used to provide elastic support, the lever 5 is used to facilitate user operation, and the connecting rod 6 is used to connect the lever 5 and the positioning block 7. The staff can drive the positioning block 7 to move by moving the lever 5 to squeeze the damping rod 3, which is convenient for personnel operation. By loosening the lever 5, the damping rod 3 loses pressure and generates thrust, which pushes the positioning block 7 to move, so that the positioning block 7 fits the surface of the desired installation position, and the circuit board can be positioned.

[0032] Reference Figure 1 and Figure 3 The buffer assembly includes two abutment plates 8, which are fixedly connected to the left and right sides of the bottom of the PCB board 1 respectively, and two damping rods 2 9 are fixedly connected to the bottom of the two abutment plates 8. The bottoms of the two opposing ends of the two abutment plates 8 are fixedly connected with connecting blocks 13, and the two connecting blocks 13 are rotatably connected with driving rods 15 inside. The two driving rods 15 are rotatably connected with movable disks 16 at the opposing ends. The damping rods 2 9 and the bottoms of the movable disk 16 are fixedly connected with rubber pads 10, and the top of the movable disk 16 is fixedly connected with a movable rod 17, and the top of the movable rod 17 is fixedly connected with a top plate 11. The inside of the connecting block 13 is fixedly connected with a rotating rod 14, and the driving rod 15 is specifically rotatably connected to the connecting block 13 through the rotating rod 14. The interiors of the plurality of damping rods 2 9 are all sleeved with compression springs 12, and the top of the top plate 11 is fixedly connected with a sponge pad 18.

[0033] Specifically, when the circuit board is being positioned, the PCB board 1 moves downward, and the push plate 8 applies pressure to the damping rod 29. The damping rod 29 and the compression spring 12 are used to provide elastic support. When the push plate 8 squeezes the damping rod 29, the driving rod 15 rotates in the connecting block 13, thereby driving the movable disk 16 to move upward. The driving rod 15 is used to transmit motion, and the movable disk 16 is used to rotate and connect the two driving rods 15. The movable rod 17 is used to connect the top plate 11 and the movable disk 16. When the movable disk 16 moves, the movable rod 17 drives the top plate 11 to move toward the bottom of the PCB board 1 accordingly. The sponge pad 18 is used to protect the PCB board 1, and the rubber pad 10 is used to buffer the pressure to prevent excessive pressure from causing the movable rod 17 to move too fast, thereby damaging the PCB board 1.

[0034] Working principle: First, by moving the lever 5, the lever 5 squeezes the damping rod 3 and drives the positioning block 7 to move through the connecting rod 6. According to the required installation position, release the lever 5, the damping rod 3 loses pressure and resets to generate thrust, which easily pushes the lever 5 to move. When the lever 5 moves, the positioning block 7 moves to the required installation position, and the position of the PCB board 1 is determined according to the positioning block 7.

[0035] Secondly, when the PCB board 1 is positioned in a vertical position, the resisting plate 8 squeezes the damping rod 9 and when the resisting plate 8 moves, the driving rod 15 rotates around the rotating rod 14 inside the connecting block 13. When the driving rod 15 rotates, the movable plate 16 drives the movable rod 17 to move upward, thereby contacting the bottom of the PCB board 1 through the top plate 11 and the sponge pad 18, thereby cooperating with the two resisting plates 8 to stabilize the PCB board 1.

[0036] 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 substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
