Abstract

PROBLEM TO BE SOLVED: To provide an adapter for a faucet which copes with a situation without being influenced by a difference in the shape of the faucet, such as a round shape and a square shape, and besides is simply and removably mounted without a need for fastening a nut. SOLUTION: A short pipe-form adapter body A with a thick section is formed such that a water passage 1 formed of a soft material, having a rebound force, as a material and extending along an axial direction is formed approximately in the central part of a section and connection port parts 2 are formed in the two end parts of the water flow passage 1. At least one connection port part 2 of the tubular adapter body comprises combination of a round section hole part 2a having a bore lower than that of the faucet; and a square section hole part 2b connected to the round section hole part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet adapter used for attaching terminal equipment such as a car washing hose or a water purifier to a water tap.

[0002]

2. Description of the Related Art Conventionally, as a faucet adapter used for mounting this type of terminal equipment, it is detachable to a faucet and a terminal equipment receptacle by tightening a nut through packing to prevent detachment due to water pressure. The one that can be attached to the camera was generally used.

[0003]

However, the faucet adapter has a connection portion corresponding to the diameter, shape, etc. of the receptacle of the terminal device in advance, but each of the faucet adapters does not have a connection portion for the tap of the water supply. There is a limit due to the difference in diameter and shape of faucets such as round and square shapes depending on the home.As a result, there is a negative effect such as water leakage and detachment after installation, and this is a dedicated faucet that can respond to the connection part of both Since an adapter must be prepared, not only the handling is complicated, but also the mounting work is complicated due to the fact that these are fixed by tightening the nuts.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks of the conventional products, and has a difference in the diameter of a faucet, a round shape,
It responds without being affected by differences in the shape of the faucet, such as a square,
Moreover, it is an object of the present invention to provide a faucet adapter which can be easily and detachably mounted without requiring nut tightening.

[0005]

SUMMARY OF THE INVENTION The present invention has been made on the basis of the above, and is characterized in that a water passage along the axial direction is formed substantially in the center of the cross section using a soft material having elasticity as a material. At least one connection port of the thick-walled short tubular adapter body formed with connection ports at both ends of the water passage has a combination of a round hole having a cross section smaller than the diameter of the faucet and a square hole having a cross section connected thereto. This is a faucet adapter.

In the present invention, the round cross-section hole is formed so as to be located on the insertion port side in order to improve the workability of fitting the faucet into the connection port section. It is preferable that the diameter is a frustoconical hole having a diameter gradually increasing, and the diameter of the hole on the insertion port side is 10 mm in view of the workability of fitting and the fixability after mounting as the size of the round hole in cross section. Hereinafter, it is preferable that it is preferably about 5 to 8 mm.

The rectangular cross section is formed so that the length of the diagonal line of the rectangular cross section is substantially the same as the diameter of the round cross section due to the fixability after mounting. Is preferred.

In addition, the thickness of the thick short tubular adapter main body is determined by the workability of mounting the connection port to the faucet and the fixing property by the tightening caused by the elastic force after the mounting. It is preferable to use one formed so as to have the same or larger diameter.

Further, as a soft material having a resilient force, which is a material of the adapter body, a Shore hardness of 10 to 10 is considered from the viewpoint of the workability of attaching the connection port to the faucet and the fixability after the attachment.
It is preferable to use an elastomer such as 30 silicone rubber or urethane rubber.

[0010] The thickness of the adapter body at the insertion port side is preferably formed to be slightly thinner by providing a step portion in order to improve the fitting property of the connection port portion to the faucet.

[0011]

According to the present invention, there is provided a thick and short wall formed by using a soft material having elasticity as a raw material, forming a water passage along the axial direction at a substantially central portion of the cross section, and forming connection ports at both ends of the water passage. Since it is made of a tube, the connecting port is brought into contact with the faucet, and the port is pressed and pressed to be elastically inserted. Further, at least one of the connecting ports is smaller in diameter than the diameter of the faucet and has a circular hole having a cross-sectional shape and a rectangular hole having a cross-sectional shape connected thereto. Round,
Although it is fitted to various faucets of different shapes and sizes, such as squares, it does not leak or fall off during use because it is tightly adhered.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a faucet adapter according to an embodiment of the present invention. FIG. In the figure, A shows an adapter body integrally molded by injection molding using silicone rubber (Sievetsu Chemical's silicone rubber KE1950-10) as a material, and an outer portion provided with steps at both ends. Length 7 with a diameter of 40 mm
It is formed in a thick short tube of 0 mm.

In the drawing, reference numeral 1 denotes a water passage formed of a round hole having a diameter of 8 mm and formed in a substantially central portion of the cross section of the adapter main body A along the axial direction.
The figure shows connection ports formed at both ends of the water passage 1, wherein the connection port 2 on the faucet side has a circular truncated conical hole 2a having a diameter of 8 mm and a length of 20 mm and a truncated cone. ,
It is formed so as to be composed of a combination of a rectangular hole 2b having a length of 20 mm and a diagonal line of 8 mm connected thereto.

In the drawing, B denotes a faucet, and reference numeral 3 denotes a step having a depth of 5 mm and a length of 5 mm provided on the side of the connection port 2 of the adapter body A to the faucet B. It is shown.

Since the faucet adapter of the present invention has the above-mentioned structure, when it is used, first, as shown in FIG. 4, the faucet B is brought into contact with the round hole 2a of the connecting port 2 in section, and then the tip of the faucet B is used. It is attached by pressing while rotating until the portion reaches the rectangular cross-section hole portion 2b.

[0016]

As is apparent from the above description, the faucet adapter of the present invention is formed by using a soft material having elasticity to form a water passage along the axial direction at a substantially central portion of the cross section, and at both ends of the water passage. At least one connection port of the thick short tubular adapter body having a connection port formed in the portion has a combination of a round hole having a cross section smaller than the diameter of the faucet and a square hole having a cross section connected thereto. Since the connection port to the faucet is composed of a combination of a round hole having a cross section smaller than the diameter of the faucet and a square hole having a cross section connected thereto, various faucets having different shapes and sizes such as round and square shapes. Even when fitted, the faucet is in close contact with one of the holes in a water-tight manner, and this is firmly fixed by tightening with a thick-walled short tubular adapter body made of a soft material having elasticity. No water leakage or separation.

Further, since the circular hole having a circular cross section is formed in a truncated cone shape, the circular hole having a circular cross section is brought into contact with a faucet, and the hole is attached by rotating and pressing the hole.
It can be easily and removably attached without complicated work such as tightening of a nut like a conventional product.
