[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-3 As shown, a plug-in type multilayer circuit board includes:

[0029] Frame 1, wherein a support rod 2 is fixedly installed inside the frame 1;

[0030] A fixed frame 9 is arranged in a linear array on the support rod 2 and rotates to engage with it. The top of the fixed frame 9 is provided with symmetrically arranged limiting grooves 14.

[0031] A ball block 13 is symmetrically arranged at the bottom of the fixed frame 9 and slidably engaged, with the bottom end of the ball block 13 inserted into an adjacent limiting groove 14;

[0032] Circuit board 10 is inserted into the mounting bracket 9.

[0033] Specifically, by sequentially installing circuit boards 10 into the mounting brackets 9, the circuit boards 10 installed in multiple mounting brackets 9 can be easily plugged together. When a circuit board 10 in one of the mounting brackets 9 is damaged, the mounting bracket 9 with the damaged circuit board 10 is driven to rotate, causing the mounting bracket 9 with the damaged circuit board 10 to disengage from the multiple adjacent mounting brackets 9 and move out of the frame 1. This allows workers to quickly remove the circuit board 10 installed in the mounting bracket 9 for repair. After the circuit board 10 is repaired, the mounting bracket 9 is pushed to rotate along the support rod 2 and return to the frame 1, causing the ball block 13 installed at the bottom of the mounting bracket 9 to be inserted into the limiting groove 14 opened at the top of the adjacent mounting bracket 9. This allows the ball block 13 and the limiting groove 14 to cooperate with each other to fix the multiple mounting brackets 9 together. When the multiple mounting brackets 9 are fixed together, it is convenient to plug in multiple layers of circuit boards 10 together.

[0034] In the above embodiments, when a circuit board 10 installed in one of the multiple mounting brackets 9 is damaged, the mounting bracket 9 with the damaged circuit board 10 is rotated by turning it, causing the mounting bracket 9 with the damaged circuit board 10 to separate from the multiple mounting brackets 9 and move out of the frame 1. This allows the worker to quickly remove the circuit board 10 installed in the mounting bracket 9. In the multi-layer mounting brackets 9, no matter which layer of the circuit board 10 is damaged, by driving the mounting bracket 9 with the circuit board 10 to rotate and move out of the frame 1, the worker can disassemble and repair the damaged circuit board 10. This not only allows for the disassembly of a single damaged circuit board 10, but also improves the repair and installation efficiency of multi-layer circuit boards 10.

[0035] As a further embodiment of this utility model, the side wall of the support rod 2 is provided with sleeves 7 arranged in a linear array, and a fixing frame 9 is fixedly connected to the side wall of the sleeves 7.

[0036] Specifically, by installing the fixing frame 9 on the sleeve 7, the sleeve 7 can rotate under force, causing the fixing frame 9 to rotate along the support rod 2, thereby allowing the fixing frame 9 to rotate out of the frame 1, making it convenient for workers to repair the circuit board 10 installed on the fixing frame 9.

[0037] As another embodiment of this utility model, the sleeve 7 is provided with slots 8 arranged in a circular array.

[0038] Furthermore, the support rod 2 has grooves 3 arranged in a linear array, the grooves 3 are connected to the slots 8, and the grooves 3 are provided with slots 4 arranged in a circular array, the side walls of the slots 4 being engaged with the slots 8.

[0039] Specifically, the groove 3 inside the support rod 2 is connected to the slot 8, so that the locking block 4 installed in the groove 3 can be locked in the slot 8 to fix the sleeve 7, so that the sleeve 7 is locked on the support rod 2 and cannot rotate, thereby fixing the fixing bracket 9 installed on the sleeve 7, so that the circuit boards 10 installed on the fixing bracket 9 can be plugged into each other.

[0040] As another embodiment further provided by this utility model, a drive rod 5 is movably installed inside the support rod 2, and a traction rope 6 arranged in a circular array is provided on the side wall of the drive rod 5, with one end of the traction rope 6 fixedly connected to the locking block 4.

[0041] Specifically, when a circuit board 10 is damaged and needs repair, the drive rod 5 is rotated to wind up the traction rope 6. The traction rope 6 can pull the locking block 4 out of the slot 8, so that the sleeve 7 is unlocked. This allows the fixing frame 9 to be rotated out of the frame 1 along the support rod 2 when it is moved, in cooperation with the sleeve 7. This makes it convenient for workers to disassemble and repair individual circuit boards.

[0042] As a further embodiment of this utility model, the bottom end of the fixing frame 9 is provided with a sliding groove 11, a spring 12 is fixedly installed in the sliding groove 11, and a ball block 13 is fixedly installed on the end face of the spring 12.

[0043] Specifically, when multiple fixtures 9 are on the same axis, the spring 12 pushes the ball block 13 to extend out of the slide groove 11 and insert it into the limiting groove 14 opened at the top of the adjacent fixture 9, so that multiple fixtures 9 can be inserted together, thereby maintaining a vertical arrangement between multiple fixtures 9, and making it easier for the circuit board 10 installed in the fixture 9 to be inserted together.

[0044] Working principle: By removing multiple circuit boards 10 and installing them into the array's mounting bracket 9, the circuit boards 10 installed in the multiple mounting brackets 9 can be easily plugged together. When one of the multiple circuit boards 10 is damaged, the drive rod 5 is rotated, causing the drive rod 5 to wind up the traction rope 6, thereby causing the traction rope 6 to pull the locking block 4 out of the locking slot 8 and release the locking of the sleeve 7. When the sleeve 7 is released, the worker can move the mounting bracket 9, causing the mounting bracket 9 and the sleeve 7 to rotate along the support rod 2, thereby fixing the... The bracket 9 can rotate out of the frame 1. When the bracket 9 rotates out of the frame 1, the worker can disassemble the damaged circuit board 10 on the bracket 9. After the damaged circuit board 10 is repaired, the bracket 9 extending out of the frame 1 is pushed back into the frame 1, so that multiple brackets 9 are arranged side by side. When multiple brackets 9 are arranged side by side, the spring 12 pushes the ball block 13 to engage in the limiting groove 14 at the top of the adjacent bracket 9, so that multiple brackets 9 are inserted together, preventing the brackets 9 from moving during use.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, 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.
