Description

Quick joint improved structure

This creation is related to the structure of the quick joint, and in particular to a quick joint improved structure in which the reset action is indeed and not easily damaged.

As shown in FIG. 6 , the conventional quick connector is mainly composed of a body 61 , an elastic member 62 and a sleeve 63 , wherein the elastic member 62 is sleeved between the body 61 and the sleeve 63 and has A circular ring-shaped elastic ring 64 can be pressed against the elastic ring 64 by the protrusion 631 when the sleeve 63 is pressed down, so that the elastic ring 64 can generate a returning force to drive the sleeve 63 to be reset. However, in the practical use, the elastic ring 64 having a circular ring shape is liable to cause the elastic ring 64 to be distorted and deformed due to the unevenness of the lower pressure passage, thereby causing the elastic function to be lowered to affect the effect of the resetting.

As shown in FIG. 7 , in another embodiment, the reset structure of the conventional quick connector is mainly provided with a plurality of elastic legs 72 of two or two sets on the elastic member 71 , and an elastic space 73 is formed between the two elastic legs 72 . And the inner wall of the sleeve 74 is provided with a push block 75 corresponding to the elastic space. When the sleeve 74 is pressed down, the push block 75 can simultaneously push the two elastic legs 72 to expand and form a crimping force. The elastic force is restored, and the sleeve 74 can be lifted and reset. However, since the push block 75 pushes the two elastic legs 72 at the same time, the lower pressure path is dispersed to the two elastic legs 72, and there is a problem that the resilience is poor. In particular, when the two elastic legs 72 are pushed up by the push block 75 and are outwardly expanded and deformed on both sides, the outward direction of the suspension ends of the two elastic legs 72 does not move along the arc of the circumferential path along the inner wall of the sleeve 74, but The linear direction moves in the opposite direction, and the inner wall of the sleeve 74 is rubbed, causing wear of the elastic foot suspension end or the inner wall of the sleeve. In addition, if the biasing force of the pressing sleeve 74 is not uniform in actual use, the deformation amount of the elastic legs 72 of the same group may be inconsistent, and the elastic function may be reduced to affect the resetting problem. .

In view of this, how to improve the above-mentioned shortcomings is the primary issue that the creative office wants to solve.
