Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hose connector for connecting a gas hose or the like, and more particularly to a hose connector for easily connecting or disconnecting a gas hose or the like while maintaining airtightness. .

[0002]

[Prior art]

 Conventionally, various hose connectors for connecting gas hoses have been used. For example, as shown in FIG. 4, the hose connector is provided at the central portion of the tip wall of the connector body 1a. The gas hose 7a is pushed into the hose connecting pipe 6a, and the circumference of the gas hose 7a is tightened with a ring-shaped metal band 15. The connector main body 1a is attached to the wall of a general household. It is used when setting and connecting a gas hose for cooking.

As a hose connector for connecting the hose for high-pressure gas, as shown in FIG. 5, a hose connecting pipe 6b projecting from the center of the tip wall of the connector body 1b, A high pressure gas hose 7b is pushed in, and a hose tightening annular valve 16 is caulked and pressed around the gas hose 7b by press working, and is connected to the wall of a factory or the like. It is used when the tool body 1b is set and the high-pressure gas hose is connected.

[0004]

[Problems to be solved by the device]

 However, the gas hose that pushes the gas hose 7a into the hose connecting pipe 6a of the connector main body 1a and tightens the circumference of the gas hose 7a with the ring-shaped metal band 15 is the gas hose. 7a can be easily connected and the gas hose 7a can be easily connected and disconnected repeatedly, but it cannot be used for high pressure gas due to its poor airtightness, and the gas hose 7a is used as a foot. If it is hooked or pulled strongly, the metal band 15 may be loosened and the gas hose 7a may come off, resulting in poor safety.

In addition, the high-pressure gas hose 7b is pushed into the hose connecting pipe 6b of the connector body 1b, and the hose tightening annular valve 16 is pressed around the gas hose 7b. The one that has been caulked and tightened by processing has good airtightness and can be used for high-pressure gas, but the gas hose 7b will not come off even if the gas hose 7b is caught on the foot or pulled strongly. The gas hose 7b cannot be removed unless the hose tightening annular valve 16 is broken, and the gas hose 7b cannot be easily connected and disconnected repeatedly.

[0006]

[Means for Solving the Problems]

 The present invention has been made as a result of various studies in view of the present situation. A screw is provided on the outer peripheral wall to provide a through hole in the axial center portion, and a hole for communicating with the through hole of the axial center portion in the central portion of the tip wall. And a taper surface that spreads toward the rear portion is provided on the outer peripheral wall, and at least one split groove in the axial direction is provided on the taper surface. A hose-tightening annular valve that fits through a hose to a hose connecting pipe protruding from the center of the end wall of the connector body, and an outer circumference of the hose-tightening annular valve at the inner wall end. A taper surface that slides in contact with the wall taper surface is provided internally, and a screw thread that engages with a screw thread provided on the outer peripheral wall of the connector body is provided on the inner peripheral wall that is connected to this taper surface, and The hose connector is configured with an operating cap that fits into the annular valve for tightening the screw and is screwed to the outer peripheral wall of the connector body, and has good airtightness. Not only can it be used for high-pressure gas, but it can also be easily connected and removed from the hose repeatedly, and the hose will not come off even if the hose is hooked on the foot or pulled strongly. In this way, handling is safe and convenient.

A thread 14 is provided on the inner peripheral wall of the connector body 1 which is screwed to the thread 2 provided on the front of the outer wall of the connector body 1, and is fitted to the annular valve 9 for tightening the hose so that the outer periphery of the body 1 of the connector is connected. I try to screw it on the wall.

[0011]

[Action]

 The hose connector of the present invention is constructed as described above, and when it is used as a fuel gas hose connector at home or in a factory, the rear part of the connector body 1 is attached to the wall of the home or factory. After being set and fixed, the gas hose 7 is fitted to the hose connecting pipe 6 which is integrally projected on the central portion of the tip end wall of the connector main body 1, and then the gas hose 7 is previously attached to the gas hose 7. The hose tightening annular valve 9 that has been fitted is fitted to the outer peripheral portion of the gas hose 7 fitted to the hose connecting pipe 6.

Then, as shown in FIG. 2, the screw 14 provided on the inner peripheral wall of the operating cap 12 that is fitted in the gas hose 7 in advance is connected to the main body of the connector as shown in FIG. 1 When it is screwed into the front thread 2 and advanced, the taper surface 10 provided on the outer peripheral wall of the hose tightening annular valve 9 is attached to the taper surface 10 provided on the inner peripheral wall of the operating cap 12. The taper surface 13 of the operation cap 12 is tightened by the taper surface 13 of the operation cap 12 as the operation of the operation cap 12 is advanced.

By this tightening, the annular groove 9 for hose tightening is pressed by the operation of the four axially dividing grooves 11 provided on the taper surface 10 and bites into the gas hose 7. , The gas hose 7 is connected in a completely airtight state.

Therefore, the gas hose 7 connected to the connector main body 1 is airtightly connected, and can be used not only for low pressure gas for home use but also for high pressure gas used in factories and the like. . Further, the gas hose 7 will not come off even if the gas hose 7 is strongly pulled by being caught on the foot.

When removing the gas hose 7 from the connector main body 1, the actuating cap 12 is retracted and separated from the thread 2 on the front part of the connector main body 1, and then the hose tightening annular valve 9 is attached. When retracted and released from the gas hose 7 fitted to the hose connecting pipe 6, the gas hose 7 is unfastened, and the gas hose 7 is pulled out as it is. For example, the gas hose 7 is removed from the connector main body 1.

Therefore, the gas hose 7 can be easily removed from the connector main body 1, and the gas hose 7 can be easily connected to and removed from the connector main body 1 for easy handling. It is convenient.

In the hose connector of the present invention shown in FIGS. 1 to 3, four split grooves 11 are provided in the taper surface 10 of the annular valve 9 for tightening the hose. The number of the grooves 11 is not limited, and at least one groove 11 may be provided in the axial direction.

Further, a turning knob or the like may be attached to the actuation cap 12, and when the turning knob is attached and the actuation cap 12 is actuated, the gas hose can be connected and disconnected more easily.

Furthermore, this hose connector can be used by attaching the connector body to, for example, an air gun or the like that uses compressed air, and is not limited to use at home or in a factory. . Further, the type of gas flowing through the hose is not particularly limited.
