[0031] The present utility model provides a detachable buckle structure.
[0032] Please refer to Figures 1 - 4, the detachable buckle structure 10 is provided on the housing 20. The housing 20 has an inner cavity. The housing 20 includes a cover plate 21. The inner cavity is provided with a circuit unit 30. The housing 20 is provided with a mounting groove 22 that cooperates with the cover plate 21, and the circuit unit 30 can be taken out from the mounting groove 22. In this embodiment, the circuit unit 30 is mounted on the cover plate 21.
[0033] The detachable buckle structure 10 includes a buckle 12 and a snap 11. A plurality of the buckles 12 are arranged at intervals on the upper and lower inner walls of the mounting groove 22. A plurality of the snaps 11 protrude from the inner side surface of the cover plate 21 corresponding to the plurality of the buckles 12, and the snaps 11 cooperate with the buckles 12.
[0034] The snap 11 has a clamping portion 111 and a connecting portion 112. One end of the connecting portion 112 is connected to the inner side surface of the cover plate 21, and the other end of the connecting portion 112 is connected to the clamping portion 111. The connecting portion 112 passes through the buckle 12 and the clamping portion 111 abuts against the inner side wall of the housing 20 to fix the cover plate 21 in the mounting groove 22.
[0035] A first guiding inclined surface 1111 is inclined on one side of the clamping portion 111. The first guiding inclined surface 1111 is used to guide the clamping portion 111 to disengage from the buckle 12 during the disassembly of the cover plate 21. When disassembling the cover plate 21, pry up one end of the cover plate 21 along the inclined direction of the first guiding inclined surface 1111. After being stressed, the clamping portion 111 disengages from the buckle 12 along the first guiding inclined surface 1111 to achieve disassembly.
[0036] As above, for the detachable buckle structure 10 proposed by the present utility model, the cover plate 21 is fixed to the housing 20 through the cooperation of the clamping portion 111 of the snap 11 and the buckle 12; by arranging the circuit unit 30 on the inner side of the cover plate 21, the disassembly of the circuit unit 30 is made more convenient; when disassembling the cover plate 21, the first guiding inclined surface 1111 of the clamping portion 111 guides the clamping portion 111 to disengage from the buckle 12, and the first guiding inclined surface 1111 prevents the snap 11 from breaking during the loosening process, realizing convenient loosening of the buckle structure and multiple uses.
[0037] Please refer to Figure 3 and Figure 5 , the inclination angle of the first guiding inclined surface 1111 is 7° to 17°. More specifically, the inclination angle of the first guiding inclined surface 1111 refers to the angle of the included angle α between the first guiding inclined surface 1111 and the horizontal plane, and the angle of the included angle α is 7° to 17°.
[0038] It can be understood that if the included angle α is too large, it is difficult for the first guiding inclined surface 1111 to guide the clamping portion 111 to disengage from the buckling position 12, then it is difficult to disassemble the buckle 11, which affects the convenience of disassembly, and may even cause the buckle 11 to break when disassembling the buckle 11; if the included angle α is too small, the first guiding inclined surface 1111 is relatively easy to guide the clamping portion 111 to disengage from the buckling position 12, but it will make the buckle 11 easy to loosen and affect the clamping effect. After multiple tests, when the angle of the included angle α is within the range of 5° to 20°, the convenience of disassembly and the clamping effect can be compatible. Preferably, the angle of the included angle α is 7° to 17°. Those skilled in the art can specifically set the angle of the included angle α to 7°, 9°, 11°, 13°, 15°, 17°, etc., and there is no unique limitation here.
[0039] Please refer to Figure 3 and Figure 6 , a second guiding inclined surface 1112 is provided at one end of the clamping portion 111 facing the inner cavity of the housing 20, and the second guiding inclined surface 1112 is connected to the first guiding inclined surface 1111. The second guiding inclined surface 1112 is used to guide the clamping portion 111 to insert into the buckling position 12 during the installation process of the cover plate 21, so as to make the engagement between the buckle 11 and the buckling position 12 smoother.
[0040] The inclination angle of the second guiding inclined surface 1112 is 24° to 35°. More specifically, the inclination angle of the second guiding inclined surface 1112 refers to the angle of the included angle β between the second guiding inclined surface 1112 and the horizontal plane, so the angle of the included angle β is 24° to 35°.
[0041] It can be understood that if the included angle β is too large, it is difficult for the second guiding inclined surface 1112 to guide the clamping portion 111 to insert into the buckling position 12, which affects the convenience of installing and inserting the buckle 11 into the buckling position 12; if the included angle β is too small, it will affect the original height of the clamping portion 111, make the buckle 11 easy to loosen, and affect the clamping effect. After multiple tests, when the angle of the included angle β is within the range of 20° to 40°, the convenience of installation and the clamping effect can be compatible. Preferably, the angle of the included angle β is 24° to 35°. Those skilled in the art can specifically set the angle of the included angle β to 24°, 26°, 28°, 30°, 32°, 35°, etc., and there is no unique limitation here.

[0044] The inclination angle of the third guiding inclined surface 114 is 7° to 27°. More specifically, the inclination angle of the third guiding inclined surface 114 refers to the angle of the included angle θ between the third guiding inclined surface 114 and the horizontal plane, and the angle of the included angle θ is 7° to 27°.
[0045] It can be understood that if the included angle θ is too large, it is difficult for the third guiding inclined surface 114 to guide the clamping portion 111 to insert into the buckling position 12, which affects the convenience of installing and inserting the buckle 11 into the buckling position 12; if the included angle θ is too small, it will affect the original thickness of the guiding portion 113, making the buckle 11 prone to looseness and affecting the clamping effect. After multiple tests, when the angle of the included angle θ is within the range of 5° to 30°, it can be compatible with the convenience of installation and the clamping effect. Preferably, the angle of the included angle θ is 7° to 27°. Those skilled in the art can specifically set the angle of the included angle θ to 7°, 12°, 17°, 22°, 27°, etc., which is not uniquely limited herein.
