[0023] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0024] Please refer to Figures 1-5 , an embodiment of the present invention provides a technical solution: a conveniently used PCB board processing fixture, including a mounting seat 1, a mounting groove 2 is opened on the mounting seat 1, the mounting groove 2 is used for placing the circuit board 14, a clamping seat 4 is rotatably arranged in the mounting groove 2 through a rotating shaft 3, the clamping seat 4 is rotatably arranged to facilitate the installation of the circuit board 14, and an adjustment seat 6 is slidably arranged in the mounting groove 2, a first sliding groove 7 adapted to the adjustment seat 6 is opened in the mounting groove 2, the adjustment seat 6 slides horizontally along the first sliding groove 7, a clamping groove 5 is opened on the clamping seat 4 for placing the circuit board 14, a sliding seat 8 is slidably arranged on the adjustment seat 6, the sliding seat 8 slides horizontally along the adjustment seat 6, and a limiting component is arranged in the adjustment seat 6 for limiting and fixing the adjustment seat 6, an inclined surface 13 is arranged on the sliding seat 8, and a fixed groove 12 is opened on the sliding seat 8, so that when the circuit board 14 presses the inclined surface 13, it can drive the sliding seat 8 to slide, enabling the circuit board 14 to enter the fixed groove 12 to realize the fixation of the circuit board 14.

[0025] In the present utility model, through the cooperation of the mounting base 1, the clamping seat 4, the adjusting seat 6 and the sliding seat 8 provided, the fixing of the circuit board 14 can be realized only through one mounting base 1. During use, only one end of the circuit board 14 needs to be inserted into the clamping groove 5, and then the circuit board 14 is rotated to enter the mounting groove 2. During the mounting process, the circuit board 14 presses the sliding seat 8 to slide open and enter the fixing groove 12, realizing the automatic clamping and fixing of the circuit board 14. This design facilitates the installation and removal of the circuit board 14. Moreover, through the provided limiting component, the position of the sliding seat 8 can be adjusted to adapt to circuit boards 14 of different specifications, expanding the scope of use, and solving the problem that the existing PCB processing fixture needs to use a bottom plate and a cover plate to fix the circuit board 14, and the bottom plate and the cover plate are fixed by magnetic attraction, which is inconvenient to operate.

[0026] In another embodiment provided by the present utility model, a slider 9 is arranged on the sliding seat 8, a second sliding groove 10 adapted to the slider 9 is opened on the adjusting seat 6, a first elastic member 11 is arranged in the second sliding groove 10, one end of the first elastic member 11 is connected to the slider 9, and the other end is fixed in the second sliding groove 10. The first elastic member 11 is a compression spring, and its elastic acting force is used to drive the sliding seat 8 to slide back to its original position, and the elastic force of the first elastic member 11 causes the sliding seat 8 to clamp the circuit board 14. This design can realize the automatic clamping of the circuit board 14.

[0027] In another embodiment provided by the present utility model, a torsion spring is sleeved on the rotating shaft 3, and the elastic force of the torsion spring can realize the rotational reset of the clamping seat 4, making it rotate and extend out of the mounting groove 2, facilitating the installation of the circuit board 14.

[0028] In another embodiment provided by the present utility model, the limiting component includes a sliding block 15 that slides vertically in the adjusting seat 6 and a friction plate 22 that slides horizontally in the adjusting seat 6. The fixing of the adjusting seat 6 is realized through the friction between the friction plate 22 and the first sliding groove 7. A sliding rod 16 is arranged on the sliding block 15, the sliding rod 16 slides vertically along the adjusting seat 6, a pressing plate 17 is arranged on the sliding rod 16, and a second elastic member 18 is sleeved outside the sliding rod 16. The second elastic member 18 is used to drive the sliding rod 16 to slide back to its original position; a connecting rod 19 is slidably arranged in the adjusting seat 6, the connecting rod 19 slides horizontally along the adjusting seat 6, one end of the connecting rod 19 is connected to the friction plate 22, and the other end is provided with a movable shaft 21. An inclined groove 20 is opened on the sliding block 15, and the movable shaft 21 is movably arranged in the inclined groove 20. This design facilitates the adjustment and fixing of the adjusting seat 6 to meet the fixing requirements of circuit boards 14 of different specifications.

[0029] In another embodiment provided by the present utility model, when the sliding block 15 moves downward, the connecting rod 19 drives the friction plate 22 to slide and contract into the adjusting seat 6, so that the friction plate 22 disengages from the first sliding groove 7, and then the adjusting seat 6 can be slid to adjust its position.

[0030] In another embodiment provided by the present utility model, the second elastic member 18 is a compression spring, and its elastic force is used to drive the sliding block 15 to slide back to its original position.

[0031] In another embodiment provided by the present utility model, the movable shaft 21 is rotatably connected to the connecting rod 19, which can reduce the friction between the movable shaft 21 and the inclined groove 20.

[0032] During actual use, one end of the circuit board 14 is placed into the clamping groove 5, and the clamping seat 4 is driven to rotate by rotating the circuit board 14. When the circuit board 14 rotates to the position of the inclined surface 13, the sliding seat 8 is squeezed to slide to the right (refer to Figure 3 ), so that the circuit board 14 enters the installation groove 2 and aligns with the fixing groove 12. At this time, the sliding seat 8 loses the extrusion force, and the elastic restoring force of the first elastic member 11 drives the sliding seat 8 to slide back to its original position to clamp and fix the circuit board 14. When the circuit board 14 needs to be taken out, only the sliding seat 8 needs to be slid so that the circuit board 14 is disengaged from the fixing groove 12 and can be taken out. After the circuit board 14 is taken out, the elastic force of the torsion spring drives the clamping seat 4 to rotate back to its original position;

[0033] When the position of the sliding seat 8 needs to be adjusted, pressure is applied to the pressing plate 17, so that the sliding rod 16 drives the sliding block 15 to move vertically downward. During this process, under the action of the inclined groove 20, the connecting rod 19 is driven to move in the direction of the sliding block 15, thereby driving the friction plate 22 to slide into the adjusting seat 6 and disengage from the first sliding groove 7, and then the position of the sliding seat 8 can be slidably adjusted. Similarly, after the pressing plate 17 is released, the elastic restoring force of the second elastic member 18 drives the sliding rod 16 and the sliding block 15 to move upward and return to their original positions, so that the connecting rod 19 pushes the friction plate 22 to slide out of the adjusting seat 6 and press against the first sliding groove 7 to fix the adjusting seat 6.

[0034] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
