Description

Integral adapter with one-touch coupling {INTEGRATED PLATE TYPE ADAPTER OF ONETOUCH COUPLING}

The present invention relates to an integrated adapter of one-touch coupling, and more specifically, by directly connecting to the fastener of the hose without a separate part to minimize leakage, while maintaining airtightness, reduced parts, ease of assembly, and can reduce the manufacturing cost An integrated adapter of one-touch coupling.

In general, when connecting a hose to transfer fluid, one-touch coupling is used as a connecting means.

Two types of such one-touch couplings are widely used as shown in FIGS. 1 and 2.

First, as shown in FIG. 1, a one-touch coupler 1 having a hose connected to one side and an adapter 2 corresponding thereto are provided, and a nipple 4 between the adapter 2 and the hose fastener 3. Is provided.

In the above structure, the adapter 2 is inserted into the one-touch coupler 1, and then lightly tightened both handles of the one-touch coupler 1 so that both hoses are hermetically connected.

In addition, as shown in FIG. 2, a one-touch coupler 1 to which a hose is connected to one side and an adapter 2 are correspondingly provided, and a nipple 4 between the adapter 2 and the hose fastener 3. A) is prepared.

In the above structure, when the lock ring 1a of the one-touch coupler 1 is retracted back, the adapter 2 is inserted and the lock ring 1a is released. Both hoses are hermetically connected.

However, the conventional one-touch couplings shown in FIGS. 1 and 2 have the following problems.

First, the conventional adapter (2) can not be directly connected to the hose fastener (3) to use them to connect the nipple (4), which is a separate part, so the number of parts increases, assembly is inconvenient, and the production cost increases There was a problem.

In addition, the conventional adapter (2) has a connection between the adapter (1) and the nipple (4), the nipple (4) and the hose fastener (3), when the fluid to be conveyed is a high pressure is less airtight, There was a risk of safety accidents due to leakage.

The present invention is intended to provide an integrated camlock adapter that can be directly connected to the fastener of the hose without any additional parts to minimize leakage, while realizing airtightness, reduced parts, ease of assembly, reducing manufacturing costs.

The present invention is an adapter that is inserted and fastened to the coupler of the one-touch coupling, the thread is processed on the outer peripheral surface of one end of the body so as to be directly fastened to the fastener of the hose and to maintain the airtightness when inserted into the fastener of the hose Tapered surface is processed at the end, characterized in that the nut is formed to protrude from the body.

In addition, the body is characterized in that the thread, tapered surface, the nut is formed by processing a single steel pipe.

According to the present invention, there is a very practical effect that can be directly coupled to the hose fasteners without a separate part to minimize leakage, while reducing airtightness, reduced parts, ease of assembly, manufacturing cost.

In particular, by processing a single steel pipe to form a screw thread, tapered surface, nut, the inner surface is smooth, there is an effect that the fluid flow is smooth and excellent in strength can be used safely even in the environment of ultra-high pressure.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the integrated adapter of the one-touch coupling according to the present invention.

Figure 3 is an exploded perspective view of the one-touch coupling applied to the integrated adapter according to the present invention, Figure 4 is a cross-sectional view of the integrated adapter according to the present invention, Figure 5 is an exploded view of another type of one-touch coupling applied to the integrated adapter according to the present invention Perspective view.

First, as shown in FIGS. 2 and 3, the integrated adapter 10 according to the present invention is inserted into and coupled to the coupler 1, and one side of the body 11 to be directly coupled to the fastener 3 of the hose. However, the thread 12 is processed on the outer peripheral surface.

In addition, the body 11 of the integrated adapter is machined with a tapered surface 13 at the end of the threaded line 12 to maintain airtightness when inserted into the fastener 3 of the hose.

The body 11 of the integrated adapter has a nut 14 formed to protrude from the body 11 so that it can be easily tightened or loosened with a monkey wrench, spanner, or the like. Here, the thread 3-1 is formed on the inner surface of the fastener 3 of the hose, and the tapered surface 3-2 (extended type) is formed at the end thereof so as to correspond to the tapered surface 13 (converging type) machined on the body 11. ) Is processed.

According to the above technical configuration, when the threaded portion 12 is processed on one side end outer circumferential surface of the body 11 is rotated in one direction while being inserted into the fastener 3 of the hose, tightened by screwing integrally When fastened and fully tightened, the tapered surface 13 of the body and the tapered surface 3-2 of the hose fitting are in close contact with each other to have airtightness between the two parts.

Thereafter, the integrated adapter 10 is inserted into the coupler 1, and then lightly tightened both handles of the integrated coupler 1 so that both hoses are hermetically connected.

Next, the one-piece adapter 10 according to the present invention is made of a single steel pipe, the threaded line 12, the tapered surface 13, the nut 14 is integrally formed in the body (11).

As described above, the present invention realizes cost reduction by integrating a conventional nipple and an adapter to reduce the number of parts.

In addition, the present invention allows the adapter to be fastened directly to the fastener of the hose, the airtightness is high by minimizing the connection portion, the assembly is very excellent by reducing the number of parts.

In addition, the present invention is manufactured by using a single steel pipe, so that the fluid flow in the pipeline is smooth and excellent in strength, so that it can be safely used even in an ultra high pressure environment.

Next, FIG. 5 is an exploded perspective view of another type of one-touch coupling to which an integrated adapter according to the present invention is applied. As shown in the drawing, the coupler 1 is provided with a lock ring 1a, and the lock ring 1a. After retreating), the integrated adapter 10 is inserted into the coupler 1 and then the lock ring 1a is released. Both hoses are hermetically connected.

As described above or the foregoing, cost reduction is realized by integrating a conventional nipple and an adapter to reduce the number of parts.

In addition, it is possible to fasten the adapter directly to the hose fasteners to minimize the connection portion, the air tightness is high, the number of parts is very good assembling is excellent.

And since it is manufactured using a single steel pipe, the fluid flow in the pipeline is smooth and the strength is excellent, so it can be used safely even under the environment of ultra high pressure.

 The above description is an embodiment of the present invention, it will be apparent that the present invention is not limited to the technical idea and can be variously implemented within the technical idea described in the utility model registration claims attached to the present specification.
