Description

Novel key structure

Technical Field

The utility model relates to a wrist-watch technical field especially relates to a novel button structure.

Background

With the wide application of wearable devices, the performance requirements of consumers on smart watches are increasing. The anti-pulling limiting mechanism of the existing intelligent watch key is complex in structure, complex in assembly process and easy to fall off. The most opening rands that adopt of current stop gear, to mass production's product, the rand card can appear the condition of out-of-position, even use laser welding to remedy, also has the production of rosin joint scheduling problem, leads to the quality unstable, and the pulling force is not enough.

SUMMERY OF THE UTILITY MODEL

The embodiment of the utility model provides a technical problem who solves provides a novel button structure to make the assembly simple and be difficult for droing.

In order to solve the technical problem, the embodiment of the utility model provides a novel key structure is provided, wear to locate the intraductal button of bata including the bata pipe of locating on the wrist-watch watchcase and sliding, the button comprises key axle and the key cap of establishing at the key axle front end, the longitudinal section of button is "T" type, and in the bata pipe was worn to locate in the key axle slides, seted up the round recess on the key axle tail end outer wall, the cover was equipped with the rand of "O" type on the recess, and the external diameter of rand is greater than the key axle diameter.

Further, still include gasket and spring, the internal diameter of banjo front end is greater than the internal diameter of tail end, still is equipped with the rubber ring between the medial surface of banjo front end and the key shaft outer wall, and gasket and spring housing are located on the key shaft, and spring one end acts on the key cap, and the other end passes through the gasket and acts on the banjo.

Further, the rand adopts silica gel material to make.

The utility model has the advantages that: the utility model discloses can effectively prevent to drop, stability is high, simple structure, simple process, it is with low costs.

Detailed Description

It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict, and the present invention is further described in detail with reference to the accompanying drawings and specific embodiments.

In the embodiment of the present invention, if there is directional indication (such as upper, lower, left, right, front, and rear … …) only for explaining the relative position relationship between the components and the motion situation under a certain posture (as shown in the drawing), if the certain posture is changed, the directional indication is changed accordingly.

In addition, the descriptions of the first, second, etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying any relative importance or implicit indication of the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

Referring to fig. 1 to 3, the novel key structure of the embodiment of the present invention includes a key, a barrel 4 and a retainer ring 5.

The barrel 4 is arranged on the watch case 1. The key is slidably arranged in the barrel 4. The key is composed of a key shaft 3 and a keycap 2 arranged at the front end of the key shaft 3. The longitudinal section of button is "T" type, and key shaft 3 slides and wears to locate in the bustle 4, has seted up the round recess on the 3 tail end outer walls of key shaft, and the cover is equipped with rand 5 of "O" type on the recess, and the external diameter of rand 5 is greater than the 3 diameters of key shaft. Preferably, the inner diameter of the collar 5 is equal to the inner diameter of the key shaft 3 at the bottom of the corresponding groove. When the O-shaped clamping ring 5 is assembled, the O-shaped clamping ring is directly pressed into the groove of the key shaft 3, so that the assembly is simple and the cost is low; the O-shaped clamping ring 5 is deformed into a quasi-triangular shape in the groove, so that the contact area between the clamping ring 5 and the inner side surface of the groove is increased, and the stability of the product quality is comprehensively improved. The utility model discloses a 5 pulling forces of rand can be stabilized more than 30 kg. The utility model discloses can replace current opening rand 5's effect, can prevent effectively that rand 5 from droing.

As an implementation mode, novel button structure still includes gasket 7 and spring 8, and the internal diameter of 4 front ends of bayon is greater than the internal diameter of tail end, still is equipped with rubber ring 6 between the medial surface of 4 front ends of bayon and the 3 outer walls of key shaft, and gasket 7 and spring 8 cover are located on key shaft 3, and spring 8 one end is acted on key cap 2, and the other end passes through gasket 7 and acts on bayon 4.

As an embodiment, the collar 5 is made of a silicone material.

The utility model discloses a button is after pressing, kick-backs through the effect of spring 8, and during the resilience, rand 5 supports in 4 tail ends of pipe, carries on spacingly, prevents that the button from droing, prevents that the user from directly extracting the button.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
