Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a hose joint that can be connected sufficiently tightly regardless of whether the shape of the water faucet is round or rectangular.

<Prior art and its problems> Conventionally, there has been a hose joint that is attached to the proximal end of a hose and can be easily installed by simply inserting it into a faucet. A gasket 3' made of an elastic material is fitted into a joint body 2' to be attached to the joint body 2', and a hose 5' is secured by tightening with a nut 4' screwed into the lower part of the joint body 2'. When it is attached to the faucet 1' and water is flowing, the water pressure pushes the gasket from the back side of the gasket 3' toward the faucet 1' side, and together with the restoring force of the gasket 3', it is firmly attached to the faucet 1'. It was a structural thing. However, in this type of conventional hose joint, the internal space of the joint body 2' and the shape of the gasket 3' used therein are round, so if the faucet is round, it will fit tightly. If the faucet is rectangular, the squares of the rectangular faucet will come into strong contact with the gasket, but on the other sides, there will be a gap or a weak force between the faucet and the gasket. It has the disadvantage that it can only come into contact with the pipe, which can cause water leakage.

Also, although it is not usually seen, it is conceivable that the shape of the joint body and packing are both rectangular as a product exclusively for rectangular faucets, but in that case, the compatibility with round faucets would be reversed. Deteriorate.

<Means for Solving the Problems> The present invention aims to eliminate the above-mentioned drawbacks and provide a hose joint that is fully compatible with both round and rectangular faucet shapes. The gist is that in a hose joint, a faucet tightening gasket made of an elastic material is provided around the inner wall of a joint body consisting of a cylindrical body with open upper and lower ends, and a hose attachment nut is superimposed on the lower part of the cylindrical body. The above-mentioned packing is formed into a cylindrical body having a circular space extending vertically through the center of a rectangular columnar body having a flange-like protrusion at its upper opening. This is a hose joint characterized in that a cavity is formed extending vertically from its lower end to slightly below the brim-shaped overhang.

The joint main body of the present invention is usually configured such that the upper member and the lower member can be fitted together by screwing or other appropriate means, and in the fitting part, the flange-like shape of the above-mentioned packing The packing is attached so that the projecting portion is fixed, and for this purpose, the peripheral shape of the brim-like projecting portion of the packing is made to match the shape of the internal space of the joint body.

<Examples and Effects> The present invention will be described in detail below with reference to drawings showing examples thereof, and the effects of the present invention will also be explained.

Fig. 1 shows a perspective view of the packing 1 used in the present invention, Fig. 2 shows a bottom view thereof, and Fig. 3 shows a sectional view thereof. The packing 1 consists of a cylindrical body 3 having a rectangular outer shape and having a space 2 with a circular cross section inside, and is provided with a flange-like protrusion 4 at the upper opening.
A hollow part 5 is formed in the square part of the flesh part of the cylindrical body 3, the upper part of which is closed, and the lower part of which is open. This packing is made of an elastic material such as rubber or flexible plastic.

In the hose joint of the present invention, as shown in FIG. 4, the above-mentioned gasket 1 is fitted into the inner wall of the joint main body 6, which is usually divided into upper and lower halves, so as to be fixed by the periphery of the brim-shaped projection 4. A nut 8 is provided at the bottom of the joint body 6 to tighten the hose 7 connected to the opening at the lower end of the joint body 6, so that the faucet 9 can be pushed out from the upper opening of the gasket 1 as shown in the figure. It is used by inserting it.
At this time, if the external shape of the faucet 9 is round, the fifth
As shown in the figure, the faucet 9 is fitted into the space 2 of the gasket 1 without much deformation of the cylindrical body 3 of the gasket 1, and the cavity 5 is hardly crushed. The packing 1 is brought into sufficient contact with the entire circumferential surface. If the faucet 9 is rectangular, the cavity 5 formed in the square part of the gasket 1 as shown in FIG.
By being crushed, the opening diameter in the square direction is expanded by that amount, and the cylindrical body 3 of the packing 1 is also considerably deformed. This is achieved naturally by crushing the hollow part 5, and the reaction from the enlarged diameter of the square part appears on the other sides, weakening the contact force of the gasket 1 against the faucet 9 on the sides. There is no such thing.

The material of the joint body 6 and nut 8 of the present invention is not particularly limited, and may be made of plastic or metal, but from the viewpoint of corrosion resistance and moldability, it is usually made of plastic. In any case, a material with some degree of hardness is used to withstand the water pressure when water is poured, and the water pressure acts on the gasket made of an elastic material, and the gasket is pushed from the back side (outside) with water pressure and tightened against the faucet 9. Make sure to give it.

Also shown in FIGS. 7 and 8 is a configuration in which a cutout 10 is provided in a part of the upper opening edge of the joint body 6 so that the faucet 9 can enter deeper into the gasket 1. Further, as shown in FIG. 9, a fixing screw 11 is attached to the peripheral side wall of the joint body 6 to further strengthen the connection to the faucet 9.

<Effects of the Invention> As described above, according to the hose joint of the present invention, by forming the hollow part in the square part of the packing, when a rectangular faucet is fitted into the circular space of the packing, By crushing the hollow part, the diameter of the corner part of the rectangular faucet is expanded without any force, and the gasket tightens the faucet firmly and almost uniformly around the entire circumference of the faucet, so it is better than a round faucet. Needless to say, it is a sufficiently tight fit for rectangular faucets, and there is no possibility of water leakage or the joint itself coming off from the faucet.
