FIG. 1 is an exploded view of an exemplary embodiment of a button device. Referring to fig. 1, the button device includes a front ring 10, a sleeve 20, and a push rod 30.

Fig. 2 and 3 are schematic structural views of the front ring. Referring to fig. 1, 2 and 3, the front ring 10 has a first connection end 12, and three first catches 14 spaced apart from each other are formed on a circumferential inner surface of the first connection end 12.

Fig. 4 is an assembly structure diagram of the button device. Fig. 5 is a schematic cross-sectional view of the button device. Referring to fig. 1, 4 and 5, the sleeve 20 has a second connection end 22, and a circumferential outer surface of the second connection end 22 is formed with a positioning portion 26 protruding in a radial direction of the sleeve 20 and a plurality of second catches 24. The second connecting end 22 coaxially extends into the first connecting end 12, and three second hooks 24 are engaged with the plurality of first hooks 14 when the positioning portion 26 abuts against the first connecting end 12. The detent 26 prevents the second connecting end 22 from extending further into the first connecting end 12, and the second catch 24 prevents the first catch 14 from retracting backwards, thereby securing the front ring 10 to the sleeve 20. Although the number of the first hooks 14 is three in the exemplary embodiment, it is not limited thereto, and in other exemplary embodiments, the number of the first hooks 14 may be adjusted according to actual needs while ensuring the spaced arrangement.

Referring to fig. 4 and 5, the push rod 30 is inserted through the front ring 10 and the sleeve 20 and is movable between an initial position and a depressed position with respect to the front ring 10 and the sleeve 20. In an exemplary embodiment, referring to fig. 1 and 5, the button device further includes a spring 50 sleeved on the push rod 30 and applying force to the push rod 30 and the sleeve 20 to move the push rod 30 toward the initial position, respectively. The inner surface of the sleeve 20 is formed with a first step 29, the outer surface of the push rod 30 is formed with a second step 32, and the first step 29 can abut against the second step 32 to limit the push rod 30 from further moving when the push rod 30 moves to the initial position under the force of the spring 50. Thereby, when the push button device is operated, the push rod 30 can be pushed inward to move from the initial position to the pushed position, and when the push rod 30 is not pushed, the push rod 30 is restored to the initial position by the spring 50.

The utility model provides a button device, preceding ring 10 is last to be used for being fixed in telescopic first buckle 14 interval ring cloth on preceding ring 10's circumference internal surface. Therefore, in the exemplary embodiment, the front ring 10 of the button device is a stainless steel front ring produced by a metal injection process and demolding in a mold forming mode by adopting an internal core pulling mode, and has better appearance and corrosion resistance. Compared with the existing front ring made of stainless steel materials and produced by a machining process, the manufacturing cost of the front ring 10 and the button device is greatly reduced.

In an exemplary embodiment, referring to fig. 1, 2 and 3, the circumferential inner surface of the front ring 10 is further formed with three positioning protrusions 16 corresponding to the first catches 14, and the plurality of positioning protrusions 16 and the plurality of first catches 14 are alternately arranged around the circumferential inner surface of the first connection end 12. The circumferential outer surface of the second connecting end 22 is further formed with a positioning groove 28 corresponding to the positioning projection 16 in shape, and the positioning projection 16 can extend into the positioning groove 28 when the second connecting end 22 extends into the first connecting end 12. The detent projections 16 cooperate with the detent recesses 28 to prevent the front ring 10 from rotating relative to the sleeve after assembly. The above structure facilitates the mold gate to be disposed on the positioning protrusion 16 because one end of the push rod 30 moves relative to the inner surface of the front ring 10, thereby making the inner surface of the front ring 10 smooth enough to ensure the operational feeling of the button device. Although the number of the positioning protrusions 16 is three corresponding to the number of the first catches 14 in the illustrated embodiment, the front ring 10 may have a plurality of mounting positions for easy assembly. However, the number of the positioning projections 16 may be adjusted according to actual requirements in other exemplary embodiments, and the front ring 10 may include only one positioning projection 16.

In an exemplary embodiment, referring to fig. 2, the positioning projection 16 protrudes out of the first connection end 12 in the axial direction of the front ring 10. Thus, when the front ring 10 is properly rotated during use, once the positioning projections 16 are aligned with the positioning grooves 28, the portions of the positioning projections 16 extending out of the first connecting end 12 are caught in the positioning grooves 28 to position the front ring 10.

In an exemplary embodiment, referring to fig. 1 and 4, the button device further includes a sealing ring 40, an inner edge of the sealing ring 40 is sleeved on the push rod 30, an outer edge of the sealing ring 40 abuts against an inner wall of the sleeve 20, and the sealing ring 40 can be deformed to move the inner edge along with the push rod 30. Thereby achieving a waterproof function between the push rod 30 and the sleeve 20.

FIG. 6 is a schematic view of another exemplary embodiment of a sleeve. The structure of the sleeve 20 in fig. 6, which is the same as that of the sleeve 20 in fig. 1, is not repeated, but the difference is that the sleeve 20 in fig. 6 is formed with a protruding portion 27 protruding in the radial direction of the sleeve 20 in each positioning groove 28, and the positioning protrusion 16 is interference-fitted with the protruding portion 27 when protruding into the positioning groove 28. The protrusions 27 are used to assist in rotation stopping and prevent play between the front ring 10 and the sleeve 20.

The utility model also provides a controlgear, including foretell button device.
