Screw cap rubber plug knob waterproof structure

Abstract

The invention relates to a screw cap rubber plug knob waterproof structure, comprising a housing and a screw cap rubber plug. The rubber plug comprises a knob. The knob is on the housing. The knob is provided with a convex hull structure in an annular manner. The convex hull structure and the housing are in extrusion interference. Since the waterproof structure is just provided with the convex hull structure and the housing which are in extrusion interference to realize waterproofness, enough interference magnitude can be set to ensure waterproof effect, and assembly is simple and convenient. Since the convex hull structure is just a local bulge protruded on the knob, no matter pulling assembling actions in an assembling process or the waterproof plug is opened and pulled to the knob in a screw cap manner in use by a user, acting forces mainly act on a main part of the knob, and an acting force on the convex hull structure is very low, so as to effectively solve problems in the prior art of waterproofing failure since the knob is pulled repeatedly.

Description

technical field [0001] The invention relates to a waterproof structure of a rubber plug, in particular to a waterproof structure of a screw cap type rubber plug handle. Background technique [0002] With people's preference for outdoor sports, waterproof, dustproof, and drop-proof three-proof electronic products are increasingly attracting people's attention. When considering the waterproof structure of the external port position of this type of electronic Screw cap waterproof plug to achieve. [0003] Please refer to figure 1 , is a structural diagram of a screw-type waterproof plug for an external port of an existing three-proof mobile phone, which includes a housing 100 and a waterproof plug 200, and the waterproof plug 200 is provided with a handle 210, and the handle 210 includes a The interference part 220, a limit part 230 and a traction part 240, the limit part 230 respectively connects the interference part 220 and the traction part 240, the housing 100 is provide...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a screw-cap type rubber stopper handle waterproof structure, which can solve the problems existing in the prior art that the assembly is difficult and difficult due to the need to ensure the waterproof reliability of the handle, and solve the above-mentioned The traction part needs to be pulled vigorously for assembly, which is easy to break and has insufficient strength. At the same time, it also solves the problem of waterproof failure in the prior art after the handle is pulled many times.
