Abstract

The utility model provides a quick joint structure which is composed of an axle sleeve, an axle bed, a spring, a sleeve, a washer, etc. Particularly, the intermediate piece of the outside of the axle sleeve is provided with a groove to make the sleeve limited in the groove at the outside of the axle sleeve by using the washer; simultaneously the inner part of the sleeve is provided with a step edge which is embodded with a spring; the quick joint structure is used for actuating the sleeve in a spring-go mode. Because the washer is arranged at the inner part of the sleeve, the states of loose and drop can not occur.

Description

Quick coupling structure

The utility model is a kind of quick coupling structure, mainly tie up to the sheathed axle bed of epimere through hole, a spring and one adapter of lock spiral shell of axle sleeve inside, allow axle bed under the elastic force of spring, just can seal the epimere through hole, and be drilled with several pearl grooves in the hypomere through hole outside of axle sleeve, for burying the positioning ball that waits number underground, and cut open in the stage casing of axle sleeve outside and to establish a groove, the while is limited in the axle sleeve outside by packing ring with sleeve, terrace edge in sleeve inner is provided with a spring in addition, and the spring-go effect of sleeve is provided; When engaging, the through hole that inserts the axle sleeve hypomere when joint can promote the state that axle bed allows upper and lower through hole maintenance be communicated with, and the groove of joint front end also can be fastened in axle sleeve positioning ball on every side; Otherwise when getting loose, positioning ball is dodged and is absorbed in terrace edge when promoting sleeve, make positioning ball lose the relation of being fastened with joint front end groove, joint is ejected in the elastic force effect meeting of axle bed simultaneously, again recover the state of sealing, what deserves to be mentioned is:, can come off so needn't worry packing ring because the packing ring of this creation is arranged on sleeve inner.

Traditional quick coupling structure, Fig. 1 are perspective exploded view.Its structure mainly comprises: elements combination such as axle sleeve 10, axle bed 20, spring 30, adapter 40, positioning ball 50, spring 60, sleeve 70, packing ring 80, joint 90 form; Wherein: the axle sleeve 10 inner terrace edges 11 that make, so as to forming epimere through hole 12 and hypomere through hole 13, and in epimere through hole 12 usefulness two sealing packing rings 14 sheathed axle beds 20, and installing one spring 30 on axle bed 20, allow axle bed 20 under the elastic force effect of spring 30, just can be closed in the epimere through hole 12 and hypomere through hole 13 of axle sleeve 10, around axle bed 20, be drilled with several open-works 21 simultaneously, as being communicated with epimere through hole 12 and hypomere through hole 13 usefulness, fix one at the screw thread 15 lock spiral shells of axle sleeve 10 outsides in addition and take over 40, hypomere through hole 13 outsides of right this axle sleeve 10 are drilled with several pearl grooves 16, positioning ball 50 for numbers such as burying underground, cut open at axle sleeve 10 root edges again and establish a groove 17, can be at a sheathed spring 60 of axle sleeve 10 hypomeres and a sleeve 70, at last utilize packing ring 80 that sleeve 70 is limited in the groove of axle sleeve 10 again, allow sleeve 70 have suitable spring-go effect; Practical operation as shown in Figure 2, during joint, joint 90 is inserted axle sleeve 10 hypomere through holes 13, axle bed 20 promptly is pushed into epimere through hole 12, make open-work 21 and upper and lower section through hole 12,13 around the axle bed 20 keep the state of connecting, simultaneously in the groove 91 of joint 90 front ends that is the positioning ball 50 around axle sleeve 10 of being fastened; The view that gets loose when habit formula shown in Figure 3 is implemented.When getting loose, only promote sleeve 70, positioning ball 50 is that sink is absorbed in the terrace edge 71 of sleeve 70, allow positioning ball 50 no longer be fastened with the groove 91 of joint 90 front ends, utilize spring 30 strength that are arranged on the axle bed 20 that joint 90 is ejected simultaneously, make axle bed 20 close upper and lower section through hole 12,13 once more; Because the packing ring of commonly using 80 is to be set in the groove 17 of axle sleeve 10 root edges, so being very easy to cause packing ring 80 to get loose when promoting sleeve 70 drops, though packing ring 80 is a slight element just, but be to be responsible for sleeve 70 is limited in a key greatly element in the axle sleeve 10, if packing ring 80 drops, whole rapid pipe joint will lose original function, and it is general to become scrap iron, and this is to commonly use the shortcoming that rapid pipe joint waits to overcome solution.

The purpose of this utility model is to provide a kind of quick coupling structure, to overcome above-mentioned shortcoming.

Major technology means of the present utility model are: will originally make groove at the axle sleeve root edge and make stage casing at axle sleeve, simultaneously sleeve is limited in the axle sleeve outside by packing ring, make the packing ring outside originally being revealed in be hidden in sleeve inner, make when promoting sleeve, can not cause packing ring to get loose and drop, guarantee the normal working life of rapid pipe joint.

A kind of quick coupling structure, mainly by: elements combination such as axle sleeve, axle bed, spring, adapter, positioning ball, sleeve, packing ring, joint form; Take at the sheathed axle bed of the epimere through hole of axle sleeve inside, a spring and one, allow axle bed under the elastic force of spring, be closed in the epimere through hole, and establish several pearl grooves, and the positioning ball of number such as bury underground in the hypomere through hole outside of axle sleeve; It is characterized in that: the middle section of this axle sleeve outside is cutd open and is established a groove, is fit into one in the groove sleeve is limited in the packing ring of axle sleeve outside, and sleeve inner is established two terrace edges, is provided with a spring that makes the sleeve spring-go in two terrace edges.

Understands structure content of this creation and the function and benefit that can reach in depth for people are easy to, enumerate a specific embodiment now, and detailed introduction of conjunction with figs. is described as follows:

Fig. 1: the perspective exploded view that is the habit formula.

Fig. 2: the jointing state schematic representation when being the enforcement of habit formula.

Fig. 3: the view that gets loose when being the enforcement of habit formula.

Fig. 4: the perspective exploded view that is this creation.
