[0026] The utility model cooperates with the sliding seat 3, the clamping piece 7, the limit block 8 and the locking assembly, and the circuit board can be fixed by rotating the clamping piece 7, and the rotated clamping piece 7 is automatically locked and fixed by the cooperation of the locking assembly and the locking groove 17. At the same time, after the clamping piece 7 rotates to fix the circuit board, the sliding seat 3 can be fixed by the friction force of the friction plate and the limit groove 9. The present design can quickly realize the installation and fixation of the circuit board, and the circuit board can be taken out without removing the mounting plate 1 during maintenance or replacement, which saves time and effort, and solves the problem that the circuit board in the prior art is installed with screws, and the installation and disassembly both require the help of external tools, the maintenance or replacement efficiency is low, and the screws are easily lost.

[0027] Preferably, four sliding seats 3 are provided in total to improve the stability of fixing the circuit board.

[0028] In another embodiment provided by the utility model, the locking assembly includes a locking block 12 slidably arranged on the clamping member 7, the locking block 12 slides horizontally along the clamping member 7 and can be retracted into the clamping member 7, a first elastic member 13 is arranged between the locking block 12 and the clamping member 7, a second slider 14 is slidably arranged on the clamping member 7, and a second slide groove 16 adapted to the second slider 14 is opened on the clamping member 7, and a transmission rod 15 is arranged between the locking block 12 and the second slider 14. In this design, by cooperating with the second slider 14 and the transmission rod 15, the transmission rod 15 can drive the locking block 12 to slide by sliding the second slider 14, that is, the locking block 12 slides and retracts into the clamping member 7, so as to facilitate the disassembly of the circuit board.

[0029] In another embodiment provided by the utility model, a rounded corner is provided on the locking block 12, so that when the clamping piece 7 rotates, the locking block 12 is squeezed and slides and shrinks into the clamping piece 7, that is, in the process of the clamping piece 7 rotating to clamp and fix the circuit board, the locking block 12 is squeezed and can slide and shrink, which does not affect the rotation of the clamping piece 7, and after the clamping piece 7 presses the circuit board, the locking block 12 can be reset and inserted into the locking groove 17, so as to realize the locking and fixation of the clamping piece 7 after rotation.

[0030] In another embodiment provided by the utility model, the first elastic member 13 is a compression spring, and its elastic force drives the locking block 12 to slide and reset. That is, when the locking block 12 and the clamping member 7 rotate to the position corresponding to the locking groove 17, the locking block 12 loses the squeezing force, and the elastic restoring force of the first elastic member 13 drives the locking block 12 to slide and reset and insert into the locking groove 17.

[0031] In another embodiment provided by the utility model, the transmission rod 15 is an L-shaped structure, and one end of the transmission rod 15 is fixedly connected to the locking block 12, and the other end is fixedly connected to the second slider 14, so that when the second slider 14 slides, it drives the locking block 12 to slide and retract into the clamping member 7, that is, by sliding the second slider 14, the transmission rod 15 drives the locking block 12 to slide out of the locking groove 17, thereby unlocking the clamping member 7.

[0032] In another embodiment of the present invention, a torque spring 11 is provided on the rotating shaft 6, and the elastic force of the torque spring 11 is used to drive the clamping member 7 to rotate and reset, that is, to drive the clamping member 7 to rotate and reset after the clamping member 7 is unlocked.

[0033] In another embodiment provided by the utility model, a clamping plate 18 is slidably provided on the clamping member 7, and the clamping plate 18 is connected to the clamping member 7 by a second elastic member 19. The second elastic member 19 is a compression spring, and its elastic force can realize the reset of the clamping plate 18 after the clamping member 7 is reset. At the same time, the elastic force of the second elastic member 19 makes the clamping plate 18 press against the circuit board to improve the fixing effect, and a rubber pad is provided on the clamping plate 18, which has a certain protective effect to avoid damage to the circuit board.

[0034] In actual use, the position of the sliding seat 3 is adjusted according to the size of the circuit board. After adjusting to a suitable position, the circuit board is placed on the placement plate 5, and then the pressing piece 7 is rotated so that the pressing piece 7 rotates toward the circuit board, driving the pressing plate 18 to press the circuit board and fix the circuit board. During the rotation of the pressing piece 7, the rounded corners on the locking block 12 are squeezed by the placement plate 5 and the mounting plate 1 to slide into the pressing piece 7 and shrink into the pressing piece 7. When the pressing piece 7 is rotated to the position as shown in the figure, the pressing piece 7 rotates to the position as shown in the figure. Figure 3 The position shown, that is, the circuit board is pressed, and at the same time, the locking block 12 rotates to the position of the locking groove 17 with the movement of the pressing member 7. At this time, the locking block 12 loses the extrusion force, and the elastic restoring force of the first elastic member 13 causes the locking block 12 to slide and reset to extend out of the pressing member 7 and insert into the locking groove 17, so as to fix the pressing member 7. At this time, the limiting block 8 rotates into the limiting groove 9, and the friction between the friction plate and the limiting groove 9 is used to fix the sliding seat 3, so as to achieve the purpose of limiting and fixing the circuit board.

[0035] When the circuit board needs to be removed, the second slider 14 is slid so that the transmission rod 15 drives the locking block 12 to slide into the clamping piece 7 and retract to disengage from the locking groove 17. At this time, the first elastic piece 13 is in a retracted state. Then the clamping piece 7 is rotated to disengage the limit block 8 from the limit groove 9 and unlock the sliding seat 3. At this time, the elastic force of the torque spring 11 drives the clamping piece 7 to rotate and reset, and the elastic restoring force of the first elastic piece 13 drives the locking block 12 to slide and reset, and the circuit board can be taken out.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. 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 invention.
