After the hose 1 is inserted by the return spring 75, the second inclined surface 71 of the sleeve 70 is retracted from the locking claw 50 to be spaced apart to thereby quickly restore the locking claw 50, The hose 1 is brought into contact with the outer periphery of the hose 1 so that the hose 1 can be fixed by the locking crown 50.

As described above, the present invention facilitates separation and disassembly in the case of misassembly, thereby preventing the components from being damaged during the separation.

The hose valve assembly of the present invention having the above structure is assembled by the following method.

First, a sealing ring 30 is inserted into the second hollow portion 21 of the case 20 so that the inner end of the sealing ring 30 is caught by the second step 21b of the case 20.

The backing ring 40 is inserted into the second hollow portion 21 of the case 20 so that the inner end of the backing ring 40 is caught by the third step 21c of the case 20.

The locking crown 50 is inserted into the second hollow portion 21 of the case 20 so as to be brought into contact with the outer end of the back ring 40.

The collar 60 is inserted and fixed to the case 20 so that the backing ring 40 and the locking claw 50 are not pulled out.

The sleeve (70) is inserted into the collar (60) to prevent the sleeve (70) from coming off the collar (60).

In this case, the assembly for the hose valve of the present invention is completed and the state shown in FIG. 1 is obtained.

In this state, the hose 1 is inserted into the sleeve 70 so that the end of the hose 1 is caught by the first step 21a of the case 20 as shown in Fig.

When the hose 1 is inserted, the locking claw 50 is elastically deformed to be in contact with the first inclined surface 41 of the back ring 40 so that the hose can be inserted. After the hose 1 is inserted, 50 are elastically restored to be in contact with the outer circumferential surface of the hose 1, thereby preventing the hose 1 from being disengaged in the direction opposite to the hose inserting direction.

When the hose 1 is removed, the sleeve 70 is pushed into the collar 60 so that the second inclined surface 71 of the sleeve 70 contacts the locking claw 50 as shown in FIG. 3, The crown 50 is resiliently deformed so as to be in contact with the first inclined surface 41 of the back ring 40. In this case, the locking crown 50 is separated from the outer circumferential surface of the hose 1, so that the hose 1 can be separated.

In the present invention, there are two configurations for confirming whether or not the hose is connected in place at the time of hose coupling.

First, the configuration of the push switch 80 and the indicator lamp (not shown) is adopted.

7, the push switch 80 is provided at the inner circumference positioned between the first step 21a and the second step 21b of the case 20. It is further preferable that the push switch 80 is provided at a position close to the second step 21b. The push switch 80 is pushed by the outer periphery of the inserted hose 1. [

The indicator (not shown) is provided outside the case 20 and serves to check the state of the hose by pressing the push switch 80 by the outer circumference of the hose 1 .

As a result, the inserted hose 1 passes through the seal 30 to prevent leakage of water, so that it can be confirmed that the hose 1 is coupled to the correct position.

The second configuration adopts the configuration of the through hole 25 formed in the case 20 and the leakage check ring 90.

8 and 9, the through hole 25 is formed in the inner periphery of the case 20 between the first step 21a and the second step 21b of the case 20, So as to penetrate in the peripheral direction.

8 and 9, the leak check ring 90 is rotatably coupled to the outer periphery of the through hole 25, and a communication hole 91 communicating with the through hole 25 is formed When the hose 1 is not inserted into the correct position, the leak check ring 90 is rotated so that the through hole 25 and the communication hole 91 are aligned with each other as shown in FIG. 8 Thereby confirming the insertion of the hose 1 into the correct position.

When the inserted hose 1 passes through the seal 30 and is located at the rear of the through hole 25, the outer circumference of the hose 1 and the inner circumference of the case 20 come into contact with each other, 25 and the communication hole 91 are made to coincide with each other, it is possible to confirm that the hose 1 is connected in the correct position because there is almost no leakage amount. On the other hand, if the inserted hose 1 is positioned at the front of the through hole 25, if the through hole 25 and the communication hole 91 are made to coincide with each other, It can be confirmed that it is not. In this case, the hose 1 may be further inserted into the case 20 to position the hose 1 in position.

When the water leakage confirmation is completed, the leak check ring 90 is rotated so that the through hole 25 and the communication hole 91 are shifted from each other (see FIG. 9).

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Accordingly, such modifications and changes are within the scope of protection of the present invention as long as it is obvious to those skilled in the art.
