Abstract

(57) [Summary] [Purpose] It can be inserted into a hose connection port of faucet, equipment, etc. with a relatively small force, and further, the adhesion to the outer surface of the hose connection port, that is, the sealing property is further improved. [Structure] An inner hose 3 made of a super soft material and having a cylindrical wall of an appropriate thickness is provided inside a hose body 1 formed by winding a reinforcing wire 2 in a spiral shape in an axial direction. As a result, the inner hose 3 is deformed (compressed) according to the outer diameter of the hose connection port 4 in order by inserting the hose connection port into the hose connection port 4 so that the hose connection port smoothly moves to the hose connection port 4. Plugged into.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a pressure resistant hose in which a reinforcing wire is spirally wound and built in.

[0002]

[Prior art and its problems]

 For this type of pressure-resistant hose, a reinforcing wire made of metal or hard synthetic resin is used for the purpose of maintaining the outer shape of the hose body inside the cylindrical wall of the hose body, which is molded from flexible synthetic resin. It is generally known that it is built in a directional spiral shape, or that the reinforcing wire material coated on the outside of the hose body is wound in a spiral shape. However, when connecting by inserting into the hose connection port of a faucet or equipment, the reinforcing wire material has the effect of holding down the expansion of the hose connection port from the outside, so that the connection port can be inserted smoothly into the hose connection port. I can't. Therefore, conventionally, when connecting to the hose connection port, it was necessary to warm the connection port or apply oil to the inner peripheral surface of the connection port to handle the connection work, which is very troublesome. At the same time, even if it is warmed or oil is applied, the connection mouth held by the reinforcing wire still has to be forced open, so the user (worker) is very tired.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of such conventional circumstances, and the technical problem to be solved is that it can be inserted into a hose connection port of a faucet or a device with comparatively small force. It is an object of the present invention to provide a pressure-resistant hose with further improved adhesion to the outer surface of the connection port, that is, sealing performance.

[0004]

[Means for achieving the object]

 The technical means taken by the present invention to achieve the above object is to provide a tubular wall made of a super soft material and having an appropriate thickness inside a hose body formed by winding a reinforcing wire in a spiral shape in the axial direction. It is characterized by having an inner hose.

[0005]

[Action]

 According to the above-mentioned technical means of the present invention, when the operation of inserting the hose connection port into the hose connection port is performed, the inner hose is sequentially operated according to the outer diameter of the hose insertion port. Deform (compress). As a result, the hose connection port is inserted smoothly into the hose connection port.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, a reinforcing wire 2 is formed in a cylindrical wall of a hose body 1 made of a soft synthetic resin having flexibility and a shaft. The first embodiment is shown in which the outer side is formed into a concavo-convex shape according to the winding form of the reinforcing wire 2 by incorporating it in the direction of the inner hose 3 made of an ultra-soft material inside the hose body 1. To provide. By the way, as a method of molding the hose body 1, a hose molding material having a reinforcing wire 2 built therein and formed in a strip plate shape is formed by spirally winding it so that edges thereof are overlapped with each other.

The inner hose 3 is made of a resin-based super soft material such as a resin foam material, and the outer diameter of the inner hose 3 is the inner diameter of the hose body 1 and is molded into a cylindrical wall having a thickness of 1 mm or more. The hose is integrally inserted into the hose body 1 for interior decoration.

Thus, according to the pressure resistant hose described above, as shown in FIG. 6, by inserting the hose connection port 4 into the hose connection port 4, the inner member made of an ultra-soft material is sequentially operated. The hose 3 is inserted into the hose connection port 4 in a state of being deformed (compressed) according to the outer diameter of the hose insertion port.

FIG. 3 shows a second embodiment in which the outer side of the hose body 1 of the above-mentioned first embodiment is formed straight, and the configuration is the same as that of the first embodiment, so the same components are the same. The description is omitted by using the reference numerals.

FIG. 4 shows a third embodiment in which, in addition to the reinforcing wire 2, a chemical fiber 5 is embedded inside the cylindrical wall of the hose body 1 as shown in the drawing. The inner hose 3 is provided.

FIG. 5 shows a fourth embodiment in which the outer side of the hose body 1 of the above-mentioned third embodiment is straightly molded, and the constitutional form is the same as that of the third embodiment, so that the same components are the same. The description is omitted by using the reference numerals.

[Effect of the device]

 Since the pressure-resistant hose of the present invention is constructed as described above, by inserting the hose connection port into the hose connection port, the inner hose can be operated sequentially according to the outer diameter of the hose insertion port. The hose connection is inserted smoothly into the hose connection. Therefore, the hose body reinforced by the reinforcing wire is fitted to the hose connection port with a relatively small force without the need for pushing and expanding the hose body in accordance with the hose connection port. Can be plugged. Moreover, the inner hose deformed according to the shape of the outer surface of the hose connection port has a much higher adhesion to the outer surface than the conventional one, and its sealing property is further improved to ensure leakage of water or air. It is possible to provide a pressure-resistant hose that can be prevented.
