Abstract

A watch rear cover waterproof structure consists of a watchcase, a rear cover and a waterproof rubber pad, and is characterized in that the rear cover is connected with the watchcase via a plurality of screws arranged circumferentially, a layer of waterproof rubber pad in the shape matching with that of the bottom of the watchcase is arranged between the rear cover and the watchcase, the waterproof rubber pad tightly clings to the end surface of the bottom of the watchcase, and connecting screws penetrate through the rear cover and corresponding fixing holes on the waterproof rubber pad to be screwed into screw holes on the end surface of the bottom of the watchcase. The watch rear cover waterproof structure has the advantages of simple structure, easy processing and production, low manufacturing cost and fine waterproof performance.

Description

Wrist-watch bonnet waterproof construction

Technical field

The utility model relates to the wrist-watch technical field, especially a kind of bonnet waterproof construction that is applicable to the different shape wrist-watch.

Background technology

Water proofing property is a very important performance of wrist-watch, the general screw-in syndeton that adopts between the watchcase of circular wrist-watch and the bonnet, waterproof apron between watchcase and the bonnet can play sealing process preferably after screwing bonnet, so the water proofing property of circular wrist-watch is generally better.And the wrist-watch of different form is as square, oval or other peculiar shape, owing to the case shape reason, can't adopt circular screw-in to be connected between watchcase and the bonnet, and can only adopt forced bonnet, even adopt the wrist-watch of this rear cover structure to add waterproof apron, reach excellent waterproof property and generally be not easy very much.

The utility model content

The utility model proposes a kind of wrist-watch bonnet waterproof construction, can effectively improve the water resistance of various class wrist-watches, particularly low and middle-grade wrist-watches, improve value-added content of product.

The purpose of this utility model is achieved through the following technical solutions:

A kind of wrist-watch bonnet waterproof construction, constitute by watchcase, bonnet, waterproof pad, it is characterized in that: bonnet and watchcase interconnect by a plurality of screws along periphery, between bonnet and watchcase, place the waterproof pad of one deck and the corresponding coupling of watchcase bottom shape, this waterproof pad fits tightly at the watchcase bottom end face, and the fixed orifice that attachment screw passes on the bonnet accordingly screws in the bottom end face screw of watchcase.

The thickness of described waterproof pad is not less than 0.1mm; Watchcase bottom end face shape is any in circular, square, ellipse or the polygon.

The wrist-watch bonnet waterproof construction that the utility model proposes is to add the whole waterproof pad of a Zhang Ping between watchcase and bonnet, and fixes with attachment screw, has simple in structurely, is easy to processing, and cost is low, the advantage that water proofing property is good.
