Embodiment
In order to feature place of the present invention more can be understood, the invention provides a preferred embodiment and accompanying drawings is as follows, please refer to Fig. 1 to Fig. 3, Waterproof key structure 2 of the present invention is applied to mobile phone 1 for example, further, below illustrate it is down as benchmark using the direction of the push action of Waterproof key structure 2.The primary clustering of the mobile phone 1 of the present embodiment includes Waterproof key structure 2 and housing 3, and details are as follows for the structure of each assembly and mutual relation.
First please refer to Fig. 1 to Fig. 2, Waterproof key structure 2 includes button 10 and elastic component 20, and wherein, button 10 has press section 11 and connecting rod 12, and press section 11 is for pressing for user, and connecting rod 12 is extended by the bottom surface of press section 11 and formed.The outer peripheral face of connecting rod 12 near one end of press section 11 and indent forms minor diameter part 13, the cross sectional shape of minor diameter part 13 is for circular and its diameter is defined as D.
Elastic component 20 is roughly in hollow cone shape and expanding gradually from top to bottom, and the two ends up and down of elastic component 20 have the linearly upper shed 21 that communicates and under shed 22.
The outer rim of upper shed 21 is provided with sealing ring portion 23, the connecting rod 12 for button 10 inserts, and when button 10 inserts elastic component 20, connecting rod 12 can be protruded under shed 22 by under shed 22.The cross section of sealing ring portion 23 is roughly rounded and have larger thickness, the inner edge of sealing ring portion 23 not by cross sectional shape during external force for circular and internal diameter is defined as d, and the internal diameter d sealing ring portion 23 is not more than the diameter D of minor diameter part 13.
In addition, the outer rim of under shed 22 also optionally with in flat assembled portion 24 is connected, and the visual actual needs of those skilled in the art is changed the shape of assembled portion 24 or do not arrange assembled portion 24.
It is worth mentioning that, the present invention does not need to limit sealing ring portion 23 and is circle with the cross sectional shape of minor diameter part 13, as long as the inner edge of sealing ring portion 23 is corresponding complementary shape with the periphery of minor diameter part 13, therefore when sealing ring portion 23 and being non-circular with the cross sectional shape of minor diameter part 13, as long as the spacing of two relative inner of sealing ring portion is not more than the spacing of two opposite exterior lateral sides of minor diameter part, identical tight fit effect can be reached.
