Description

One-touch Fitting Adapter {ONE TOUCH FITTING ADAPTER}

The present invention relates to a one-touch fitting adapter, and more particularly to a one-touch fitting adapter which is firmly connected to a nipple and a nut bolt via a shearing ring, and which has an O-ring inserted into an inner circumferential surface of a bolt portion of a nut- Fitting adapter for allowing airtightness to be maintained.

As disclosed in Korean Utility Model Registration No. 20-0336038, a conventional hose connector 1 will be described with reference to FIGS. 13 to 17 attached hereto.

13, the conventional hose connector 1 has a nut 15 which is rotatable on the outside of the nipple 6 and a hexagonal head 11 is integrally formed in the middle portion of the nipple 6 And the socket 2 is fixedly mounted on the inner side of the nipple 6.

The socket 2 has a plurality of contact protrusions 3 protruding from an inner diameter of one side and a mounting portion 4 having a smaller diameter than the diameter of the portion where the contact protrusions 3 are formed.

The nipple 6 has a non-slip protrusion 8 formed on one side of its outer diameter so as to be inserted into the inner diameter of the hose 60 so as not to be pushed out. A hexagonal head 11 is integrally formed in the middle portion, (10) is formed between the socket mounting recess (9) and the non-slip projection (8), and the socket mounting recess (9) and the nut mounting recess A nut mounting portion 13 is formed at one side of the mounting groove 12 and an outer edge of the nipple 6 forms an inclined surface 14 and a flow hole 7 is formed through the center.

The nut (15) has a female screw (16) at its outer side and a mounting portion (17) at its inner side.

The socket 2 is inserted into the socket mounting groove 9 of the nipple 6 so that the mounting portion 4 is inserted into the socket mounting groove 9 so that the outer diameter of the mounting portion 4 can be adjusted by using hydraulic equipment The pressing portion 5 is formed so that the mounting portion 4 is plastically deformed so as to be in close contact with the socket mounting outer diameter 10 of the nipple 6 and the socket mounting groove 9 as shown in Figures 3 and 4 .

The nut 15 is inserted into the nut mounting groove 12 of the nipple 6 so that the mounting portion 17 is inserted into the nut mounting groove 12 and the outer diameter of the mounting portion 17 is adjusted by using hydraulic equipment The pressing portion 18 is formed so that the mounting portion 17 is plastically deformed so as not to be detached from the nut mounting groove 12 of the nipple 6 as shown in Figs. 15 and 17, 17 and the outer diameter of the nut mounting groove 12 so that the nut 15 can freely rotate.

The conventional hose connector 1 configured as above has the following problems.

In the nipple 6, the hexagonal head 11 is necessary for connection with other equipment. The hexagonal head 11 is held by a tool such as a wrench so that the hose coupling 1 itself is not rotated, and the nut 15 is fastened to the port of the hydraulic equipment In forming the hexagonal head in the nipple 6, the hexagonal steel corresponding to the outer contour of the hexagonal head 11 is used as the raw material to perform the cutting. This results in a large amount of cutting work, There is a problem that it takes a lot of time to manufacture.

Particularly, since hexagonal steel raw material is mounted on a special large lathe, it is cut while rotating to form mounting grooves and projections on the left and right sides, and drilling is performed to form a flow hole in the center, There was a rising end.

Further, when the nut 15 is fastened to the nipple 6, the mounting portion 1 is forcibly pressed to cause plastic deformation so as not to be arbitrarily separated and separated, so that the metal structure is deformed, cracks are generated, and these cracks continue to expand when the high-pressure fluid is passed therethrough, thereby causing a fatal defect in which the nut 15 itself is damaged.

The coupling structure of the socket 2 and the nipple 6 also has a problem in that the socket 2 and the nipple 6 are detached and separated due to the weak binding force since the mounting portion 4 of the socket 2 is forcibly press- Frequent occurrence.

The present invention has been made in order to meet the above-described needs of the prior art, and it is an object of the present invention to provide a nipple and a nut bolt which are firmly connected to each other via a shearing, And a hermetic seal is maintained by an O-ring.

The one-touch fitting adapter according to the first embodiment of the present invention comprises: a nipple 110 formed in a straight shape having a flow hole 111 at a central portion thereof; A socket 120 connected to the outside of the nipple 110; And a nut bolt 130 integrally connected to the hexagonal nut 131 and the bolt 132 so as to fit the nipple 110 with the socket 120 connected thereto.

The one-touch fitting adapter according to the second embodiment of the present invention comprises: a nipple 110 formed in a straight shape having a flow hole 111 at a central portion thereof; A socket auxiliary ring 160 connected to the outside of the nipple 110; A socket 120 to be fitted on the socket auxiliary ring 160 and a hex nut part 131 and a bolt part 132 which are integrally connected to each other so as to sandwich the nipple 110 in a state in which the socket 120 is connected, Type bolt 130 as shown in FIG.

According to the one-touch fitting adapter of the present invention, the nipple and the nut bolt are firmly connected to each other through the shearing, and the airtightness is maintained by the O-ring inserted into the bolt inner circumferential surface of the nut bolt and the end o- Lt; / RTI >
