DETAILED DESCRIPTION

[0024] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0025] Please refer to Figures 1-7 The utility model provides a kind of technical scheme: a kind of quick joint multilayer circuit board, including outer frame 1, the middle of the top of outer frame 1 is provided with limiting edge 5, dustproof rubber plate 2 is closely attached to the top of limiting edge 5, recess 6 is set up in the both sides in outer frame 1, reset piece 12 is provided in recess 6, reset piece 12 includes round bar 121, and the both ends of round bar 121 are rotatably connected with the inner wall of outer frame 1, torsion spring 122 is fixedly wound on the outside of round bar 121, limiting block one 123 is fixedly connected on the side of the surface of round bar 121, limiting block two 11 is fixedly set in the middle position of the inner side of recess 6, multilayer circuit board body 8 is provided in outer frame 1, rubber sleeve 9 is clamped in the both sides of multilayer circuit board body 8, and insulating plastic sleeve 7 is fixedly penetrated and arranged at the position of the corner of multilayer circuit board body 8, guide column 13 is movably arranged in insulating plastic sleeve 7, and bottom plate 4 is fixedly arranged at the bottom of guide column 13.

[0026] One end of dustproof rubber plate 2 is provided with notch 3.

[0027] The bottom of limiting block one 123 is in contact with limiting block two 11, and the bottom of torsion spring 122 is in contact with rubber sleeve 9.

[0028] The bottom of bottom plate 4 is fixedly connected with outer frame 1 by screw, buffer spring 10 is fixedly arranged around the bottom position of guide column 13, and buffer spring 10 top is in contact with insulating plastic sleeve 7.

[0029] Outer frame 1: as the support structure of entire circuit board, outer frame 1 provides stable installation environment for circuit board, and recess 6 in its inner wall provides installation space for reset piece 12.

[0030] Dustproof rubber plate 2: closely attached in the top of limiting edge 5, effectively blocks dust and sundries from entering the inside of circuit board, protects the cleanliness and normal work of circuit board. The notch 3 of one end is designed to facilitate the installation of dustproof rubber plate.

[0031] Limiting edge 5: limiting dustproof rubber plate 2, ensuring that it is closely attached on outer frame 1.

[0032] Recess 6: provides installation space for reset piece 12, and allows reset piece 12 to elastically deform when stressed, so as to realize the clamping and buffering of circuit board.

[0033] The multi-layer circuit board body 8 carries various electronic components and circuit connections.

[0034] The rubber sleeve 9 is sleeved on both sides of the circuit board and cooperates with the reset member 12 to realize clamping of the circuit board. Meanwhile, the rubber material has good elasticity and wear resistance, which can protect the circuit board from external damage.

[0035] The insulating plastic sleeve 7 is sleeved at the four corner positions of the circuit board to provide guidance and support for the guide column 13. Meanwhile, the insulating material ensures that the circuit board is isolated from other metal parts to prevent safety problems such as short circuit.

[0036] The guide column 13 cooperates with the insulating plastic sleeve 7 to ensure that the circuit board can be correctly aligned and smoothly clamped into the outer frame during installation.

[0037] The bottom plate 4 is fixedly connected to the outer frame 1 through screws to provide stable support for the entire circuit board.

[0038] The buffer spring 10 is compressed during the installation of the circuit board to provide an elastic force upward for the circuit board. When the circuit board is installed in place, the elastic action of the buffer spring 10 makes the circuit board tightly adhere to the outer frame, improving the stability of the circuit board.

[0039] When installing the circuit board for the first time, the dustproof rubber plate 2 is pried out through the gap 3, at this time the circuit board is pressed downward along the inner wall of the outer frame 1 until the guide column 13 smoothly passes through the insulating plastic sleeve 7. In this process, the rubber sleeve 9 at both ends of the circuit board presses the protruding part of the torsion spring 122, and the protruding part of the torsion spring 122 will retract into the groove 6 under stress until the rubber sleeve 9 is pressed to a certain extent, the protruding part of the torsion spring 122 pops up, and the buffer spring 10 is partially compressed. At this time, the circuit board will rise under the elastic action of the buffer spring 10, and the protruding part of the torsion spring 122 buffers the rubber sleeve 9, and the limiting block one 123 contacts the limiting block two 11 to prevent the pop-up height of the torsion spring 122.
