Waterproof mechanism

Abstract

A waterproof mechanism includes a seat body, a waterproof rubber ring and a board body. The seat body has a first receiving space and a second receiving space in communication therewith. The second receiving space is longer and wider than the first receiving space. A platform is formed at a junction between the first and second receiving spaces. An inclined sidewall extends from the platform to surround and define the second receiving space. The waterproof rubber ring is disposed in the second receiving space in tight abutment with the platform and formed with a perforation in communication with the first receiving space. The waterproof rubber ring has an inner periphery and an outer periphery. The inner periphery is formed with a connection channel for connecting with the board body. The outer periphery is formed with a protrusion section protruding from the outer periphery to the inclined sidewall in abutment therewith.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a waterproof mechanism, and more particularly to a waterproof mechanism having multiple waterproof seals to enhance waterproof performance and achieve excellent waterproof effect.BACKGROUND OF THE INVENTION[0002]Please refer to FIGS. 1A, 1B and 1C. A conventional waterproof mechanism 1 includes a waterproof rubber ring 10, a board body 13 and a seat body 15. The seat body 15 includes a first receiving space 151 and a second receiving space 152. A platform 154 is formed at the junction between the first and second receiving spaces 151, 152. An upright sidewall 155 extends from the platform 154 to surround and define the second receiving space 152. The waterproof rubber ring 10 is disposed in the second receiving space 152. The waterproof rubber ring 10 is formed with a perforation 101 in communication with the first receiving space 151. The waterproof rubber ring 10 has an inner periphery and an outer periphery. The inner p...

AI Technical Summary

Benefits of technology

[0009]A primary object of the present invention is to provide a waterproof mechanism having excellent waterproof effect.

[0010]A further object of the present invention is to provide the above waterproof mechanism having multiple waterproof seals for enhancing waterproof performance.

[0011]To achieve the above and other objects, the waterproof mechanism of the present invention includes: a board body; a seat body having a first receiving space and a second receiving space in communication with the first receiving space, the second receiving space being longer and wider than the first receiving space, whereby a platform is formed at a junction between the first and second receiving spaces, an inclined sidewall extending from the platform to surround and define the second receiving space; and a waterproof rubber ring disposed in the second receiving space in tight abutment with the platform. The waterproof rubber ring is formed with a perforation in communication with the first receiving space. The waterproof rubber ring has an inner periphery defining the perforation and an outer periphery leaned against the inclined sidewall. The inner periphery is formed with a connection channel for connecting with the board body. The outer periphery is formed with a protrusion section protruding from the outer periphery to the inclined sidewall in abutment therewith. The waterproof mechanism of the present invention has multiple waterproof seals to enhance waterproof performance and achieve excellent waterproof effect.

Problems solved by technology

However, the conventional waterproof mechanism 1 can only provide a limited waterproof effect.

According to the aforesaid, the conventional waterproof mechanism has the following shortcomings:1. The waterproof effect of the conventional waterproof mechanism is poor.2. The conventional waterproof mechanism only has one single waterproof seal.3. The conventional waterproof mechanism has poor waterproof performance.
