Abstract

<P>PROBLEM TO BE SOLVED: To provide a water introducing connection pipe connected to a faucet of tap water and used when introducing the water. <P>SOLUTION: This water introducing connection pipe structure is composed of the water introducing connection pipe 50, and a spiral muscular protrusion part 51 formed in a single spiral or a plurality of spirals is arranged on an inside surface of this water introducing connection pipe. The muscular protrusion part is equipped with material reaction force, and is spirally wound and arranged on the inside surface of the water introducing connection pipe. Thus, even when the water introducing connection pipe is bent, the water introducing connection pipe can resist bending force so as not to be bent and flatly crushed, and promotes the smooth movement of a water flow, and also enhances flexibility of the water introducing connection pipe. When the bending force is released, since the pipe is instantly restored to an original shape by operating tensile force of the bent and deformed muscular protrusion part, excellent flexibility and stickiness are maintained. Since the muscular protrusion part can also endure water pressure of the water flow, strength of a tubular surface 52 is enhanced, so that a maximum service state is attained. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a water conduit connecting pipe, and more specifically, to a water conduit connecting pipe called a hose that is used when water is introduced by connecting to a water faucet or the like.

  The conventional plastic water conduit 10 (see FIG. 5) is characterized in that its inner surface is formed smoothly. In actual use, the user himself / herself moves the conduit 10 to stretch or stretch it. However, when the water conduit 10 is moved and bent at a large angle, the water conduit is clogged, the water flow is hindered, and the water stops. If the water flow is suddenly blocked in this way, water will blow out against the water pressure from the water source connected at one end of the water conduit, and the water conduit 10 will come off the connection end of the water source. End up. If so, one end of the water conduit 10 must be reconnected to the connection end of the water source, which is very inconvenient during use.

  In order to solve such a problem of the water conduit 10, another water conduit 20 (see FIG. 6) is provided. The water conduit 20 extends in the longitudinal direction of the inner surface of the water conduit 20 so as to extend along the entire length. A large number of ribs 22 are arranged alternately. When the water guide pipe 20 is bent, a gap is formed by the grooves 21 and the ribs 22 that are long in the longitudinal direction, so that the water flow is easily carried without interruption.

However, since the grooves 21 and the ribs 22 that are long in the longitudinal direction extend from one end portion to the other end portion of the water conduit, the material deformation that occurs when the ribs 22 come together. The acting force spreads over the entire length of the water guide tube 20, whereby the water guide tube 20 is hardened and its stickiness is reduced. For this reason, if the water guide tube 20 is wound and stored in a storage room or the like, it will be immediately affected by the reaction of the vertically long ribs 22 and will lose flexibility and occupy a wide storage area.
Further, a connecting edge portion 23 is formed at the place where the vertically long grooves 21 and the ribs 22 are combined, and this forms a weak point in the water guide pipe 20 and cannot withstand the pressure of the water flow. The edge 23 opens quickly with a crack as shown by symbol C.

  As shown in FIGS. 7 and 8, the other conduits 30 and 40 each have a plurality of ribs obliquely arranged in the longitudinal direction on the inner surface thereof, and ducts 32 and 42 for guiding the water flow are respectively formed. ing.

However, the water guide pipe 30 as shown in FIG. 7 is mainly applied to a vertical solid pipe body, and is extended to be used in a straight line state without risk of bending or folding.
The ribs or wings 31 and 41 of the water guide pipes 30 and 40 are formed in a strip shape extending obliquely, and the lengths marked with A and B still have the problem of the material deformation acting force. As a result, the hardening of the water conduits 30 and 40 progresses, and the stickiness thereof decreases. Therefore, even when the ribs 30 and 40 provided with the ribs or the wings 31 and 41 in the inside as described above are stored in the bent state, the ribs arranged diagonally are stored. Immediately under the influence of the reaction, the flexibility is lost and the storage space is widened.
In addition, the ribs or wings 31 and 41 disposed obliquely are formed with depressions and the jagged coupling edge 23, so that it becomes a weak point and cannot withstand the pressure of the water flow. As a result, the connecting edge 43 opens quickly as shown by the symbol C.

  Furthermore, since the height of the wing 41 of the water conduit 40 is 1/3 to 4/5 of the radius of the hollow portion of the tube body, only a small area remains in the center of the hollow inside of the water conduit. Before the water pipe 40 is attached to one end of a water source such as a water faucet, the wing part 41 disposed at the one end is not cut off and removed. It cannot be connected directly to the part, is inconvenient to use, and the wing part 41 impedes the water flow, slowing the water flow.

  In the present invention, ridges protruding in a spiral shape are densely arranged around the inner surface of the water conduit connecting pipe, and the material reaction force generated by the protruding ridges and the tubular surface are close to each other even though they repel each other. By forming an elastic surface that can be supported, when the water guide connecting pipe is bent, the water guide connecting pipe is immediately bent or folded by the ridge formed in a spiral shape in close contact with the inner surface of the water guide pipe. The first object of the present invention is to provide a water conduit connecting pipe that can withstand bending force so as not to be damaged, promote smooth transfer of water flow, and increase the elasticity and resistance of the water conduit connecting pipe. Objective.

  According to the present invention, a material reaction force is provided in the ridge, and the elastic surface which can be supported close to each other while repelling each other is provided by being spirally disposed around the tubular inner surface of the water conduit connecting pipe. It is another object of the present invention to provide a conduit pipe that can withstand the water pressure of the water flow and increase the strength of the tubular surface to achieve the best use condition.

  In order to achieve the above-mentioned object, the water conduit connecting pipe structure of the present invention comprises a water conduit connecting tube, and the spiral muscles arranged in an annular shape in close contact with the inner tubular surface of the water conduit connecting tube. A ridge-like ridge is formed, and this ridge-like ridge is spirally wound around the inner surface of the water guide connection pipe by a single spiral or a plurality of spirals in which a plurality of spiral ridges are simultaneously spirally wound. The material reaction force generated in the streaky ridge and the tubular surface of the conduit pipe have an elastic surface that can be supported close to each other while repelling each other. When the water connection pipe is bent, the streaky ridges arranged in close contact with the inside of the water connection pipe are not bent or flattened easily. It has a resistance to prevent the water flow from moving smoothly. In addition, when the bending force is released, the tubular surface of the water guiding connection pipe is affected by the tensile force of the curved ridge that is bent and deformed, and immediately returns to the original state. It is possible to return to the original shape, and further, the streaky ridge with material reaction force is spirally wound on the inner tubular surface of the water conduit connecting pipe, so that the pressure of the water flow is reduced. It is characterized in that it has the effect of winding up and supporting in close contact with each other so as to withstand and increase the strength of the tubular surface, thereby achieving the best use condition.

  According to a second aspect of the present invention, in the water conduit connecting pipe structure according to the first aspect, the streaky ridge is made of a single spiral or a plurality of spirals in which a plurality of spirals are spirally wound at the same time. It is arranged by being spirally wound around the inner surface of the connecting pipe, and swells in a semicircular shape from the inner surface.

  The water guide connecting pipe of the present invention is formed by closely forming the spiral protruding portion in close contact with the inner surface of the tubular shape, and the material reaction force generated by the protruding protrusion and the tubular surface. However, since it forms an elastic surface that can be supported close to each other while repelling each other, even if force is applied to the water conduit connecting pipe and it bends, the water conduit does not collapse flatly. Since the water flow can be smoothly transferred without being interrupted, it is possible to use it safely and avoid the situation where water spills out of the water conduit connection pipe, and the strength of the tubular surface can be increased. The life of the tube itself can be increased and the economic effect can be enhanced.

  In addition, the streak inside the conduit pipe is formed in close contact with the tubular surface, so that a wide central water flow path can be secured, so that the water flow can be smoothly transferred and a water source such as a water tap. Since a sufficient space that can be inserted into the connecting portion of the end portion can be secured, the end of the water conduit connecting pipe can be directly and reliably connected to the connecting portion of the faucet.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a partial perspective view, partly in section, of the water conduit connection pipe of the present invention, FIG. 2 is another partial cross-sectional partial perspective view of the water conduit connection pipe in FIG. 1, and FIG. FIG. 4 is a schematic view showing a state in which the water conduit connecting pipe of the embodiment of FIG. 3 is bent.

It is wound and arranged and swells in a semicircular shape from the inner surface.

  With such a configuration, the streaky ridge 51 is spirally wound around the inner surface of the water conduit connection pipe 50, and thus is generated by the streaky ridge 51 and the tubular surface 52 of the water conduit connection pipe 50. It is possible to form an elastic surface that allows the material reaction force to be supported close to each other while repelling each other.

  As shown in FIG. 4, when the water conduit connecting pipe 50 is bent, the streaky ridge 51 arranged in close contact with the spiral inside the water conduit connecting pipe 50 is bent over Since it can withstand the force, the water conduit 50 is not easily bent or crushed flat, so that the water flow can be smoothly transferred and the structure allows the water conduit 50 to be flexible. Sexuality is enhanced.

Further, when the bending force is released, the tubular surface 52 of the water guide connecting pipe 50 is acted on by the tensile force of the streaky ridge 51 bent and deformed, and immediately returns to its original shape.
On the other hand, when the water conduit pipe 50 is not used, it can be easily rolled up in a small size for storage by maintaining good flexibility and tenacity.

  In this way, the streaky ridge 51 provided with a material reaction force is spirally wound on the tubular surface 52, so that it can withstand the pressure of the water flow and at the same time increase the strength of the tubular surface. While providing repulsion, it has the effect of winding up and supporting it, thereby achieving the best use.
