The connecting member is composed of a connector 30, the fixture 50, the sleeve 60, the first and second springs 40, 70 and the safety fitting 90.

Specifically, the connector 30 is installed by connecting the gas cock 10 and the gas hose 20, and the coupling end 31a is provided at one end so that the gas hose 20 can be inserted. Part 31 is formed and the other end is coupled to the connection pipe 12 formed in the gas cock 10, the inner end is formed with a locking end 34, and one side of the locking end 34 is a spring groove The stepped portion 35 is formed to protrude so that the 36 can be formed, and on one side of the stepped portion 35, the inclined surface 38 has an insertion portion 33 having an insertion groove 37 formed at one side. consist of.

In addition, a first spring 40 is installed in the insertion portion 33 of the connector 30, and a fixture 50 elastically installed by the first spring 40 at the rear of the first spring 40. ) Is installed.

The fastener 50 has a first fixing end 51 bent inward to be hooked to the connection pipe 12 of the gas cock 10 at one end, and the insertion groove 37 of the connector 30 at the other end thereof. The second fixing end 53 is bent outward so as to be fixed to the second fixing end 53, and an inclined inclined part 55 is formed at the center of the first fixing end 51 and the second fixing end 53. .

In addition, the sleeve 60 is installed at the rear of the fastener 50, and a support end 61 is formed at one end thereof, and the other end of the support end 61 is in contact with the fastener 50. The contact end 63 is formed, and the separation prevention end 64 protruding from the engaging end 34 is formed at the outer circumference of the contact end 63.

The second spring 70 is inserted into the spring groove 36 to elastically support the sleeve 60.

The pressing hole 80 is installed at the outer diameter end of the gas hose 20.

In addition, a packing groove 39 is formed in the insertion part 33, and the insertion part 33 of the connector 30 is connected to the connection pipe 12 of the gas cock 10 in the packing groove 39. When combined, the packing (P) is installed to be in close contact with the inclined surface of the connection pipe 12 to maintain the airtight so that the gas does not leak to the outside during use.

Safety tool 90 is installed between the support end 61 and the insertion portion 33 to prevent the sleeve 60 from flowing, is formed in a folding type, fixed groove portion 91 on one end ) Is formed, and the other end portion is formed with a fastener 93 coupled to the fixing groove 91. Here, the fastener 93 coupled to the fixing groove 91 is not separated from the fixing groove 91 even when any external force is applied from the outside.

In addition, the safety tool 90 may be formed in various colors to distinguish the use.

Referring to the operation of the present invention configured as described in detail as follows.

First, the packing (P) is installed in the packing groove (39) formed inside the insertion portion (33) of the connector (30), and the first spring (40) and the fastener (50) are inserted into the rear of the packing (P). Install. At this time, the second fixing end 53 of the fastener 50 is inserted into the insertion groove 37.

Then, the second spring 70 is installed in the spring groove part 35 of the insertion part 33 and then the sleeve 60 is coupled to the rear of the fixture 50 by interference fit. Then, the sleeve 60 is elastically installed by the second spring (70). At this time, the contact end 63 of the sleeve 60 is located on the bottom surface of the one end of the fixture 50, the separation prevention end 64 is caught by the locking end 34 so that the sleeve 60 is inserted It is possible to prevent the departure from the unit 33 (see Fig. 2a).

When combined as described above, the gas hose 20 is coupled to the coupling portion 31 of the connector 30, and then the pressing hole 80 coupled to the outer diameter of the gas hose 20 is moved to the coupling portion 31. Let's do it. Then, the pressing hole 80 is pressed using a tool such as a press. The gas hose 20 is fixedly installed so as not to be separated from the coupling part 31.

When the connector 30 and the gas hose 20 are connected and installed, the connector 30 is coupled to the connection pipe 12 of the gas cock 10. Then, the connecting pipe 12 is inserted into the sleeve 60 elastically installed by the second spring 70 and the fixture 50 elastically installed by the first spring 40, and at the same time the first of the fixture 50 One fixing end 51 is caught between the pleats 13 and the pleats 13 formed in the connection pipe 12, the packing (P) is in close contact with the end of the connection pipe (12).

When the gas cock 10 is inserted into the insertion part 33 as described above, the safety tool 90 prevents the sleeve 60 from flowing between the support end 61 and the insertion part 33 of the slide 60. If the fixed installation is completed the assembly of the present invention (see Fig. 2b).

As described above, the present invention combines the gas hose 20 and the connector 30, and then connects the insertion part 33 of the connector 30 to the connection pipe 12 of the gas cock 10, the gas hose Insertion part 33 of the connector 30 is coupled to the gas cock 10 by one touch in the state in which the assembly 20 and the connector 30 are assembled to improve workability, and the packing installed inside the insertion part 33 ( The gas can be prevented from leaking by P).

And, if you want to remove the connector 30 from the gas cock 10, first, the safety tool 90 fixed between the support end 61 and the insertion portion 33 of the sleeve 60 is separated and then Pull the sleeve 60 in the direction of the coupling portion 31. Then, the contact end 63 of the sleeve 60 is moved along the bottom surface of the fixture 50 in the direction of the engaging portion 31, the movement of the sleeve 60 to the first spring (40). Resilient fixture 50 is opened. At this time, the separation preventing end 64 is moved along the spring groove 36, and the second spring 70 is compressed by the movement of the separation preventing end 64 (see FIG. 3A).

Then, when the sleeve 60 is completely pulled in the direction of the coupling portion 31 such that the support end 61 of the sleeve 60 contacts the end portion of the insertion portion 33, the contact end of the sleeve 60 ( 63 is a fastener 50 elastically installed by the first spring 40 is opened in the direction of the inner surface of the insertion portion 33, the first fastening is caught on the connecting pipe 12 at the same time as the fastener 50 is opened The stage 51 is spaced apart from the connecting tube 12 (see FIG. 3B).

At this time, the departure prevention end 64 is moved along the spring groove 36, the second spring 70 is compressed by the movement of the departure prevention end (64).

When the first fixing end 51 is spaced apart from the connection pipe 12, the insertion part 33 may be separated from the gas cock 10, and the gas cock 10 may be operated by the operation of the sleeve 60. The connector 30 can be easily removed.

On the other hand, the safety tool 70 can be formed in a variety of colors to distinguish the use can be distinguished between the pipe and the pipe during the gas pipe connection work can facilitate the connection work.

As described in detail above, according to the gas hose connecting structure of the present invention, a gas hose and a gas cock are connected and installed, and a crimping port is installed at the outer diameter end of the gas hose. It can be easily detached to the gas cock with a single touch without a separate tool to improve the assembly, there is an effect that can prevent the leakage of gas by the packing installed inside the insert.

And, by securely installing a safety tool between the insertion portion of the connector and the support end formed in the sleeve, even if the user and other external objects contact, the sleeve is not flown by the safety tool can use the gas more safely, Safety spheres can have a variety of colors to distinguish the pipe and the pipe when connecting the gas pipe can facilitate the connection work of the pipe.

While the invention has been shown and described with respect to certain preferred embodiments thereof, the invention is not limited to the embodiments described above, and is typically defined in the art to which the invention pertains without departing from the spirit of the invention as claimed in the claims. Anyone with knowledge of the world can make many variations.
