Description

[0001] The present invention relates to a high pressure hose,

The present invention relates to a connection structure of a high-pressure hose, and more particularly, to a structure of a high-pressure hose connected to a fluid line to improve the connection structure of the high-pressure hose, Pressure hose.

As is generally known, a high-pressure hose refers to a high-pressure hose installed in a pipeline to supply a high-pressure fluid.

That is, the high-pressure hose is used to transport high-pressure gas, oil, water and the like through a set pipe, and the use place is very large.

1 is a perspective view showing a state in which a high-pressure hose is installed on a washstand installed in a bathroom such as a general home.

As shown in the figure, water supplied from a water pipe is discharged through a water supply line through a high-pressure hose and then through a water pipe (or a water tank of a toilet) to a bathroom appliance such as a toilet seat or a washstand provided in a home bathroom.

The high-pressure hose 100 has a nipple mounted at an end thereof and connected to the water supply line of the water pipe.

However, the biggest problem of the high-pressure hose 100 as described above is that a minute gap is generated between the nipple and the high-pressure hose 100, and leakage occurs between the nipple and the high-pressure hose 100.

Of course, the amount of leakage may not be large, but the occurrence of a gap between the nipple and the high-pressure hose 100 means that the internal pressure of the high-pressure hose 100 leaks to the outside. As a result, There arises a problem that the hose 100 does not perform its function sufficiently, that is, a problem that a product is defective and the fluid can not be smoothly transferred.

This problem is solved by applying silicone to the inner peripheral surface of the high-pressure hose 100 and the outer peripheral surface of the nipple to cure the high pressure hose 100 and maintaining the airtightness between the nipple 100 and the nipple, And then the hose 100 is forcedly inserted into the hose 100 to maintain airtightness.

Accordingly, the technical problem to be solved by the present invention, that is, the object of the present invention, is to solve the structural problem of the connecting portion of the conventional high-pressure hose, and to improve the structure of the high- Thereby providing a connection structure of the high-pressure hose.

Another object of the present invention is to provide a connection structure of a high-pressure hose which can smoothly flow the fluid by improving the structure of the high-pressure hose and firmly enclosing the end of the high-pressure hose inside and outside to maintain airtightness.

In order to accomplish the above object, the present invention provides a high-pressure hose comprising: a hose for transferring fluid; a high-pressure hose mounted on an inner side of an end of the hose to be hermetically mounted and equipped with a nipple having a plurality of latching protrusions mounted on the fixture, In the connection structure, the high-pressure hose connection part includes a flange having one end of the high-pressure hose at one end of the high-pressure hose in which the nipple is fitted and the first and second stoppers at an inner circumferential surface thereof; Wherein the high pressure hose, the nipple, and the flange are integrally formed with the outer body by injecting a synthetic resin solution into a forming die arranged such that an inner side of the flange and a part of an outer end of the one end of the high pressure hose are shared. Provides the connection structure of the hose.

The present invention having the above-described configuration brings about the following effects.

First, the structure of the high-pressure hose is improved to prevent the fluid from leaking by the pressure at the connection portion of the high-pressure hose.

Second, by improving the structure of the high-pressure hose, the end portion of the high-pressure hose is firmly enclosed inside and outside to maintain the airtightness and maintain the internal high pressure, thereby smoothly flowing the fluid.

1 is an exemplary view showing a state in which a high-pressure hose is connected to a sink;
Fig. 2 is an exemplary view showing an assembling process of the high-pressure hose according to the present invention
Fig. 3 is an enlarged cross-sectional view showing a main part of the present invention

Hereinafter, preferred embodiments of the present invention for achieving the above objects will be described in detail with reference to the accompanying drawings.

FIG. 2 is a perspective view showing an assembling process of the high-pressure hose according to the present invention, and FIG. 3 is a cross-sectional view showing a main part of the present invention.

As shown in the drawing, a nipple 20 for mounting on an object to be fixed is mounted inside the end of the high-pressure hose 10 according to the present invention.

The nipple 20 is provided with a plurality of latching protrusions 21 on the outer peripheral surface thereof. The latching protrusions 21 have a wedge shape in which one side is vertical and the other side is downwardly inclined.

An external body 30 is integrally formed on one side of the high-pressure hose 10 on which the nipple 20 is mounted, on which a support protrusion 31 is formed on the outer peripheral surface of the end portion.

A flange 40 is provided at one end of the outer body 30 to receive one end of the outer body 30 and to be rotatable while being supported by the side surface of the support protrusion 31 provided on the outer body 30 Respectively.

In order to prevent fluid from leaking between the inner circumferential surface of the flange 40 and the outer circumferential surface of the outer body 30 on the inner circumferential surface of the flange 40, ) 42 are provided.

To this end, the flange 40 is disposed on a molding frame (or a mold) having a roughly drawing in the state that the nipple 20 is mounted on one side of the high-pressure hose 10, The hose 10, the nipple 20 and the outer body 30 are integrated with each other.

However, when integrating the outer body 30, an outer body is formed after a separate jig or the like is coupled to the outer body 30 such that the hole passes through the outer body 30. When the molding of the outer body is completed, So as to penetrate the holes.

When the outer body 30 is integrated by the above operation, the inner circumferential surface of the high-pressure hose 10 is embedded in the inclined surface of the latching protrusion 21 formed on the nipple 20, the primary sealing is completed, The first engaging protrusion 41 formed on the outer body 30 and the support protrusion 31 provided on the outer body 30 are completely in close contact with each other and the third sealing is completed.

Meanwhile, a packing 50 holding the airtightness is mounted between the end of the outer body 30 and the second stopping jaw 42, and the secondary sealing of the present invention is completed.

The present invention is configured such that the fluid is supplied through the high pressure hose 10 by being coupled to the fixed body using the flange 40.

As a result, the nipple 20 is inserted into one side of the high pressure hose 10 according to the present invention, and the outer body 30 inserts and seals a part of the high pressure hose 10 on the outer side thereof, The outer surface of the hose 10 and the flange 40 are sealed again by the first and second stoppers 41 and 42 and the packing 50 so that the fluid moving into the interior of the high- do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the exemplary embodiments and constructions. As will be understood by those skilled in the art.

Therefore, it should be understood that the embodiments described above are intended to be illustrative and non-restrictive in all aspects and that the scope of the present invention is indicated by the scope of claims for utility model registration described below rather than the above detailed description, It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
