DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and the following embodiments are used to illustrate the present application.

[0027] For example, Figures 1 to 6As shown, the integrated circuit PCB board mounting structure includes an integrated PCB board body 1, guide posts 2, and connecting blocks 19 mounted on the integrated PCB board body. The guide posts 2 are installed at the corners of the integrated PCB board body 1, and four pairs of locking rods 5 are rotatably mounted on the sidewalls of the guide posts 2. Each pair of locking rods 5 has a movable insert rod 8 mounted on its sidewall, and the end of the insert rod 8 is inserted into the inner cavity of the guide post 2. A pull rod 3 is vertically inserted into the guide post 2, and a locking block 13 is mounted at the bottom of the pull rod 3. The locking block 13 contacts the end of the insert rod 8. Four corresponding notches 14 are opened on the surface of the locking block 13. A fixing plate 15 is mounted on the locking block 13, and a compression collar 16 is mounted on the fixing plate 15. A compression block 11 is mounted on the insert rod 8, and a bevel 12 is mounted on the compression block 11, corresponding to the compression collar 16. A serrated groove 21 is opened inside the connecting block 19, corresponding to the locking rod 5, and the locking rod 5 is in an inclined state. When unlocking the integrated PCB board body 1, the operator first needs to rotate the pull rod 3. The pull rod 3 can drive the locking block 13 to rotate, so that the notch 14 of the locking block 13 and the insertion rod 8 can correspond, thus achieving the purpose of initial unlocking. Then the operator can pull the pull rod 3 vertically. At this time, the fixing plate 15 can drive the compression collar 16 to move upward. By compressing the inclined surface 12, the entire insertion rod 8 is compressed and slids. Then the insertion rod 8 drives the locking rod 5 to rotate, so that the locking rod 5 and the serrated groove 21 are separated, thus achieving the purpose of complete unlocking. By rotating the pull rod first and then sliding it, the potential harm caused by the operator accidentally touching the integrated PCB board body and unlocking it can be avoided.

[0028] like Figures 1 to 6 As shown, in a specific embodiment, a guide groove 20 is provided inside the connecting block 19. The guide groove 20 is movably inserted into the connecting block 19, and a serrated groove 21 is provided on the side wall of the guide groove 20. The guide groove 20 facilitates the insertion of the guide post 2 and serves as a guide.

[0029] like Figures 1 to 6 As shown, a fixed seat 6 is installed at the rotation center of the clamp rod 5, and the fixed seat 6 is welded to the side wall of the guide post 2. A torsion spring 7 is installed at the rotation center of the clamp rod 5, and the torsion spring 7 is respectively engaged with the side wall of the fixed seat 6 and the side wall of the clamp rod 5. During the rotation of the clamp rod 5, the clamp rod 5 can rotate around the fixed seat 6, and the torsion spring 7 on the fixed seat 6 can rotate synchronously. The torsion spring 7 facilitates the subsequent reset operation.

[0030] like Figures 1 to 6 As shown, furthermore, a groove 10 is provided on the back of the locking rod 5, and a guide block 9 is slidably installed on the groove 10. An insert rod 8 is rotatably installed on the surface of the guide block 9, and the end of the insert rod 8 is chamfered. Through the cooperation of the groove 10 and the guide block 9, it can be ensured that the locking rod 5 can be rotated as a whole during the horizontal sliding of the insert rod 8, so as to be easily locked in the serrated groove 21.

[0031] As Figures 1 to 6 shown, further, the top of the lock block 13 is provided with a baffle plate 17, the sidewall of the pull rod 3 inside the guide column 2 is sleeved with a reset spring 18, one end of the reset spring 18 is clamped on the baffle plate 17, and the other end of the reset spring 18 is clamped on the top of the guide column 2. When the pull rod 3 slides, the pull rod 3 drives the baffle plate 17 to move, thereby compressing the reset spring 18, and the reset spring 18 facilitates later resetting, thereby ensuring the initial position.

[0032] As Figures 1 to 6 shown, further, the top of the pull rod 3 is provided with a pull plate 4, and the pull plate 4 is provided with an anti-skid groove, which facilitates later operation of the operator to pull and move the pull rod 3.

[0033] The implementation principle of the integrated circuit PCB board mounting structure is as follows:

[0034] When the integrated PCB board body 1 is installed, the operator first needs to control the notch 14 on the surface of the lock block 13 and the insertion rod 8 to correspond to each other, and then the operator inserts the installation guide column 2 and the connecting block 19 correspondingly. During the insertion process, the clamping rod 5 is extruded, the clamping rod 5 can rotate, and the insertion rod 8 can slide to the notch 14. When installed to the specified position, the operator needs to rotate the pull rod 3, drive the lock block 13 to rotate through the pull rod 3, so that the notch 14 of the lock block 13 and the insertion rod 8 are separated, thereby limiting the movement path of the insertion rod 8. At this time, the insertion rod 8 cannot move, the clamping rod 5 connected to the insertion rod 8 cannot rotate, thereby ensuring that the clamping rod 5 can be clamped in the sawtooth groove 21, thereby connecting the integrated PCB board body 1 and the connecting block 19 together, wherein the connecting block 19 is integrated with the base, and finally the installation of the integrated PCB board body 1 is completed.

[0035] When it is needed to be unlocked later, the operator first rotates the pull rod 3, drives the bottom lock block 13 to rotate through the pull rod 3, so that the notch 14 on the surface of the lock block 13 and the insertion rod 8 are aligned, thereby achieving the purpose of preliminary unlocking. Then the operator needs to pull the pull rod 3, at this time the pull rod 3 drives the baffle plate 17 to move, thereby compressing the reset spring 18, which facilitates later resetting. When the pull rod 3 slides, the pull rod 3 drives the bottom lock block 13 and the fixed plate 15 to slide upwards, the extrusion sleeve ring 16 on the fixed plate 15 extrudes the inclined surface 12 on the sidewall of the extrusion block 11 at this time, the extrusion block 11 subjected to extrusion drives the insertion rod 8 to move to the center of the guide column 2, and the guide block 9 at the end of the insertion rod 8 can move on the sliding groove 10 at this time, finally the clamping rod 5 provided with the sliding groove 10 can be driven to rotate, the clamping rod 5 can rotate synchronously at this time, and the clamping rod 5 can be separated from the sawtooth groove 21, thereby achieving the purpose of unlocking, and the integrated PCB board body 1 can be disassembled.
