DETAILED DESCRIPTION

[0018] Figures 1 to 5This is a schematic structural diagram of an embodiment of an anti-dismantling snap structure provided by the utility model, comprising an upper snap-fitting portion 1, a lower snap-fitting portion 2, a connecting column 3, an upper snap-fitting groove 4, and a lower snap-fitting groove 5. The upper snap-fitting portion 1 and the lower snap-fitting portion 2 are symmetrically arranged at the upper and lower ends of the connecting column 3. A fracture zone 6 is provided in the middle of the connecting column 3. The upper snap-fitting groove 4 and the lower snap-fitting groove 5 are respectively provided on two different shells 7. The upper snap-fitting portion 1 is inserted into the upper snap-fitting groove 4, and the lower snap-fitting portion 2 is inserted into the lower snap-fitting groove 5 to prevent the two different shells 7 from being disassembled.

[0019] The upper clamping part 1 and the lower clamping part 2 have the same structure, respectively including a left elastic clamping strip 8 and a right elastic clamping strip 9 that are symmetrically distributed in a V shape. The outer end of the left elastic clamping strip 8 is bent inward to form a left hook 10, and the outer end of the right elastic clamping strip 9 is bent inward to form a right hook 11. The left hook 10 and the right hook 11 are symmetrical to each other.

[0020] The upper snap-fit ​​groove 4 and the lower snap-fit ​​groove 5 have the same structure, respectively including an insertion groove 12, an insertion block 13 is provided in the insertion groove 12, a left groove conical surface 14 is provided on the left side wall of the insertion block 13, and a right groove conical surface 15 is provided on the right side wall of the insertion block 13. The left groove conical surface 14 and the right groove conical surface 15 are distributed in a V shape, and a left snap-fit ​​groove 16 adapted to the left hook 10 is provided on the left bottom side of the insertion block 13, and a right snap-fit ​​groove 17 adapted to the right hook 11 is provided on the right bottom side of the insertion block 13.

[0021] The fracture zone 6 is formed by a groove 18 arranged around the middle of the connecting column 3 .

[0022] The strength of the fracture zone 6 is lower than the strength of the connecting column 3 , the upper clamping portion 1 and the lower clamping portion 2 .

[0023] The upper clamping portion 1, the lower clamping portion 2 and the connecting column 3 are an integrated structure and are made by integral molding.

[0024] The upper clamping portion 1 , the lower clamping portion 2 and the connecting column 3 are made of plastic.

[0025] Working Principle: When two independent housings 7 are fixedly connected together, the upper clamping portion 1 corresponds to the upper clamping groove 4, and the lower clamping portion 2 corresponds to the lower clamping groove 5. The upper clamping portion 1 is inserted into the upper clamping groove 4, and the lower clamping portion 2 is inserted into the lower clamping groove 5. The inclined surface of the left elastic clamping strip 8 abuts against the left groove conical surface 14, and the left barb 10 is engaged with the left clamping groove 16. The inclined surface of the right elastic clamping strip 9 abuts against the right groove conical surface 15, and the right barb 11 is engaged with the right clamping groove 17, so that the upper clamping portion 1 is clamped tightly in the upper clamping groove 4, and the lower clamping groove 5 is clamped tightly in the lower clamping groove 5. Without destroying the anti-disassembly buckle structure, the two independent housings 7 cannot be separated, making it impossible to disassemble the product, thereby achieving the purpose of preventing ordinary users from disassembling.

[0026] In the process of inserting the upper clamping part 1 into the upper clamping slot 4 or inserting the lower clamping part 2 into the lower clamping slot 5, before the left elastic clamping strip 8 and the right elastic clamping strip 9 do not contact the insertion block 13, the left elastic clamping strip 8 and the right elastic clamping strip 9 are in an inward state close to each other (such as Figure 5 As shown in the figure, after the left elastic clip 8 and the right elastic clip 9 contact the insertion block 13, first, under the action of the insertion block 13, the left hook 10 and the right hook 11 are moved away from each other and opened. In the process that the left hook 10 and the right hook 11 gradually approach the left slot 16 and the right slot 17, the left elastic clip 8 and the right elastic clip 9 gradually move away from each other and are in an opened state under the action of the insertion block 13. At the same time, the left hook 10 moves along the left groove conical surface 14 until it is stuck in the left slot 16 and the right hook 11 moves along the right groove conical surface 15 until it is stuck in the right slot 17. Then, the left elastic clip 8 and the right elastic clip 9 retract, so that the left hook 10 is clamped in the left slot 16 and the right hook 11 is clamped in the right slot 17.

[0027] Since a groove 18 is provided in the middle of the connecting column 3 to form a fracture zone 6, the provision of the groove 18 reduces the cross-sectional area and strength of the fracture zone 6. When performing maintenance and disassembly, the maintenance personnel apply reverse pulling force to the shells 7 on both sides, causing the connecting column 3 to break from the fracture zone 6, and the upper clamping part 1 to fall off from the upper clamping groove 4, and the lower clamping part 2 to fall off from the lower clamping groove 5, thereby separating the two independent shells 7 and achieving the purpose of disassembling the product for maintenance. After the maintenance is completed, a new anti-disassembly buckle structure can be replaced to play the anti-disassembly role again. The structure is simple, easy to install, quick to disassemble, the pressing operation is not limited to special tools, the replacement cost is low, and the scope of application is wide. In the event of a quality damage dispute in the subsequent product, it can also prove whether the user has disassembled it privately and provide a basis for responsibility attribution.

[0028] The above detailed description is a specific description of a feasible embodiment of the present invention. The embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification that does not depart from the present invention should be included in the patent scope of this case.
