Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, a wrist-watch button buckle formula assembly structure, which comprises a housing, the casing is the cavity structure of constituteing by the inferior valve 1 of below and the 2 concatenations of top cap of top, the outside of casing still is provided with knob 3, knob 3 accessible is rotatory or presses the control that realizes the handle function, the position that the inner chamber of casing corresponds knob 3 is provided with two L type installed parts 4 and button platelet 5, press or rotatory knob 3 back button platelet 5 can receive the sense of touch and with signal transmission for PCB board 54 in order to realize corresponding function.

As shown in fig. 3 and 4, two L type installed parts 4 set up relatively, and the lower extreme of the two all is connected with inferior valve 1, and three formula structures as an organic whole, and an organic whole nature is better, guarantees the reliability of using for a long time.

As shown in fig. 4, the two L-shaped mounting members 4 are symmetrical with respect to the knob 3, the L-shaped mounting member 4 is composed of two side plates in a vertical state, wherein one side plate extends towards the adjacent side wall of the lower shell 1, the other side plate extends towards the adjacent L-shaped mounting member 4, and the side plate is further provided with a clamping groove 42, from a top view, a rectangular cavity is formed between the two L-shaped mounting members 4 and the adjacent side wall of the lower shell 1, the small key plate 5 is installed in the rectangular cavity, and the knob 3 penetrates through the side wall and is connected with the pressure sensing element on the outer wall of the small key plate 5.
