Abstract

PURPOSE: A coupler is provided to quickly combine and separate hoses without using a screw . CONSTITUTION: A female adaptor(1) has a sealing maintenance device in a sleeve(14) face, a male adaptor hanging sill in the end of the sleeve face and a tapered inclined face from the hanging sill and a sill(3) toward the bore of a hose. The female adaptor forms a tapered inclined face in a tip toward the outer diameter of the hose. The inclined face of the female adaptor is combined with the male adaptor to be extended to a hanging sill(7) of the female adaptor. An expanding portion(5) of a collet ring(6) is located in the tapered inclined face between the hanging sills of the female and the male adaptors and the end portion of the female adaptor. Thereby, the hoses are connected and separated quickly without using a screw.

Description

One touch type connecter of hose junction and hydraulic fitting}

The present invention relates to a hose assembly used for connecting hoses and hydraulic pipe fittings to pressure systems, such as heavy equipment and industrial vehicles, and more specifically, to a hydraulic hose fitting connection assembly. An improved hose connection connection system that can be quickly coupled or disconnected without

As mentioned above, there have been various proposals for a hose connection connector, but most of them are of a screw type in which a male and a male member are fitted, and such a screw connection means does not constitute a quick connection means, and thus the connection port is completed before the sealing connection is completed. The hoses typically resulted in loss of fluid during screw connections, and another problem caused by screw connections is that the hoses are sometimes difficult to properly align screws due to the stiffness of the hoses. It should not be twisted, so care must be taken when connecting. If the hose is twisted, for example, a fire hose, it may cause the hose to dance.

Thus, it is desired to have degrees of freedom for twisting the hose.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object thereof is to enable fast coupling or detachment without using screws when connecting a hose.

Another object of the present invention is to solve the problem that it is difficult to maintain proper alignment due to the rigidity of the hose when connecting the hose.

Another object of the present invention is to have a degree of freedom with respect to the twisting of the hose.

According to a preferred embodiment of the present invention hose connection connector for achieving the above object consists of an O-ring (9) and a backup ring (10) on the front sleeve 14 surface of the male adapter (1) forming a hose connector A plurality of hermetic holding means are formed, and the male adapter locking step 8 is formed at the point where the sleeve 14 surface ends.

From the male adapter locking step to the step 3, a tapered inclined surface is formed in the inner diameter direction of the hose.

The female adapter 2 coupled to the male adapter 1 forms an inclined surface tapered in the outer diameter direction of the hose at the tip portion 12, and the inclined surface extends to the female adapter engaging jaw 7.

From the female adapter locking step 7 is formed a sleeve 14 surface in contact with the sleeve 14 surface of the male adapter 1 to maintain airtightness.

The swelling part 5 of the collet ring 6 is located in the tapered inclined surface between the engaging jaw of the male and female adapters and the tip portion 12 of the female adapter.

The circular plate 13 of the collet ring 6 is formed with a plurality of cutouts 12 and the cutouts 12 is preferably about 6 to 8, but the number is not particularly limited.

A space is formed in the inner diameter direction of the circular plate 13 of the collet ring 6 so that the sleeve 14 of the male adapter 1 can be inserted therein. The swelling part 5 is extended and formed in substantially perpendicular direction.

The swelling portion 5 is elastically coupled to the disc-shaped plate member so that the sleeve 14 of the male adapter 1 larger than the inner diameter of the central portion of the disc-shaped plate member can be inserted without great resistance.

Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are a plan view and a cross-sectional view of the collet ring of the present invention.

The collet ring 6 plays a role of maintaining the airtightness of the connection port and concomitantly the connection port between the male and female adapters.

The material constituting the collet ring 6 may be selected from hard rubber, resin, or metal having elasticity according to the use pressure or application. In some cases, the disc and the swelling part of the collet ring may be formed of different materials. have.

3 is a state diagram in which the collet ring is inserted into the male adapter.

The collet ring can be easily inserted into the male adapter due to the elasticity of the disc due to the incision 12.

4 is a state diagram in which a female adapter is inserted into a male adapter into which a collet ring 6 is inserted.

When the front end portion 11 of the female adapter is inserted into the male adapter into which the collet ring is inserted, the swelling portion 5 of the collet ring is engaged with the front end of the female adapter and the engaging jaws 11 and 8 of the male and female adapters. In the tapered space.

Fig. 5 is a state diagram in which the male and female adapters are connected for colleting.

As shown in FIG. 4, when the swelling portion 5 of the collet ring 6 is positioned in the tapered space between the distal end portion 11 of the female adapter and the locking jaw 7, the male and female adapters are pulled in the axial direction. As shown in FIG. 5, the collet ring 6 is compressed at the tapered portion between the male adapter engaging jaw 8 and the female adapter tip 11 to fix the male and female adapters.

Since the pressure constituting the hydraulic system usually acts on the inside of the hydraulic system, after the fastener of the present invention is connected, the adapter is always maintained by the pressure remaining in the hydraulic system and the female adapter is needed to separate the connecting connector. After advancing in the direction of the male adapter, the collet ring 6 is brought into close contact with the step 3 of the male adapter, and the female adapter can be retracted.

In addition, a plurality of means for retaining the air constituted by the O-ring and the back-up ring 10 are formed in the sleeve 14 to which the male and female adapters contact, thereby compensating the airtight function by the collet ring 6.

Therefore, the present invention can be quickly coupled or separated without the use of screws for connection of the hose, it is possible to solve the difficulty of maintaining the proper alignment due to the rigidity of the hose when the hose is coupled as well as twisting the hose There is also an effect of freedom to the load.
