Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device can be used for a wide range of hoses with small to medium diameters, and can be connected with hoses and sprinklers, hoses and hoses, hoses and other pipes and valves. It relates to a joint that is simple and stable, and that can be economically supplied at low cost.

[0002]

[Prior art]

 In order to improve the quality or protect the above-mentioned crops from abnormal weather in the field cultivation of open-field cultivation and fruit tree, planting, flower or pot cultivation, as well as intensifying greenhouse cultivation where water management is essential. The use of hoses is increasing, and the demand for medium-diameter flat hoses, which are particularly thin and have high pressure resistance, is increasing.

Most of the hoses that have hitherto been commercially available have a small diameter, and many joints are also connected by using a hosing band of a fastening metal fitting. On the other hand, there are joints with a structure in which the bag nut and the cutter are connected by a one-touch, but since it is a separable type, it is not suitable for agriculture because dirt and muddy water accumulate inside the joint and it is difficult to remove it. It has been pointed out.

[0004]

[Problems to be solved by the device]

 In view of the above-mentioned drawbacks of the prior art, the present invention intends to provide a joint that can prevent dust and muddy water from entering the inside of the joint, and has a simple structure and is convenient to handle and use.

[0005]

[Means for Solving the Problems]

 That is, the present invention is characterized in that the bag nut of the screw connection part and the cutter of the hose connection part are integrated on the left and right, and in carrying out the invention, the bag nut is freely rotated in the circumferential direction. The invention proposes a joint which is movably integrated and has a tasling structure in which the hose is easily attached and detached.

[0006]

[Action]

 Each bag nut of the pair of joints having the above structure is screwed and fixed to the nipple to form a joint between the hose and the hose connected to the cup of the Teesling structure. It is used by connecting pipes and valves.

[0007]

【Example】

 FIG. 1 is an external view of the joint of the present invention, and FIG. 2 is a sectional view thereof. In these figures, the joint A mainly comprises a main body 1, a cutter 2, and a bag nut 3, which are molded from an industrial resin such as polypropylene, nylon or hard polyethylene.

The main body 1 has a tubular body 7 in which a fluid flow port 6 is formed, and a ridge 9 loosely fitted in a groove 8 formed in the outer periphery of the tubular body 7. The body 10 is provided, and the protrusion 9 is loosely fitted into the groove 8 by a driving method which is commonly used when joining the synthetic resin components. A peripheral groove 12 for accommodating an O-ring 11 is formed on the outer periphery near the other end of the cylindrical body 7 into which the end of a hose to be described later is to be fitted on the outer periphery on the one end side.

A plurality of cut grooves 14 are provided in the axial direction in the sleeve body 10 with a space 13 around the cylindrical body 7 for inserting a hose. A tooth sling 15 is formed, and a thread 16 is formed on the outer circumference of the tooth sling 15 in a continuous manner.

In the main body 1, a large-diameter portion 19 extending along the cylindrical body 7 via an O-ring 11 fitted in the groove 12 of the cylindrical body 7, and a large-diameter portion A seat ring 23 is formed which is continuous with a through hole 20 communicating with the flow port 6 and a small diameter portion 22 having a peripheral groove 21 formed on the outer circumference. A peripheral groove 21 is formed in the seat ring 23.

In the main body 1, an annular body 29, which is pressed against the protrusion 28 formed at the end of the seat ring 23, is fixed by ultrasonic welding on the surface in contact with the step 30 of the sleeve 10. It is connected to the sleeve 10. As a result, the seat ring 23 can freely rotate in the circumferential direction.

The cutting blade 2 is mounted on the sleeve body 10 according to the mounting of the cutting blade 2, and a tightening ring 5 having an inclined surface 4 formed on the inner wall of the end for pressing the teeth sling 15 inward. The tightening ring 5 is formed with a female thread 17 to be screwed into the male thread 16. By screwing the internal thread 17 into the external thread 16, the hose 18 whose end is inserted into the space 13 is firmly fixed between the tooth ring 15 and the cylindrical body 7. .

The bag nut 3 is composed of a bag nut body 27 having a plurality of annular projecting edges 25 formed on the outer periphery and a projecting line 24 and a screw portion 26 formed on the inner periphery. The projection 24 of the bag nut main body 27 is loosely fitted in the circumferential groove 21 by a driving operation which is commonly used when joining parts of this kind synthetic resin type. Reference numeral 31 is a packing provided on the end surface of the small diameter portion 22.

The joint A having the above-described structure is configured such that the cutter 2 and the bag nut 3 are integrated on the left and right of the main body 1 and that they can freely rotate in the circumferential direction. ing.

Practically, when connecting the hose to the hose, two joints A having the above-mentioned structure are prepared, and the ends of the hose 18 are inserted into the spaces 13 of the respective cutting plates 2, These hoses 18 are connected to the respective joint bodies A by screwing the female threads 17 of the tightening ring 5 into the male threads 16 of the cup plastic 2, and then both joints are joined using the nipple 32 shown in FIG. The A is connected.

That is, the nipple 32 is formed at both ends thereof with male threads 33 into which the female threads 26 of the bag nut 3 are screwed, whereby the hose 18 is connected as shown in FIG. It will be possible.

In practice, the hose can be connected to a sprinkler, a pump, a valve, etc., in addition to the connection between the hose and the hose via the nipple 32. In this case, these devices shall be connected to the bag nut 3 either directly or via appropriate attachments.

As described above, since the cutter 2 and the bag nut 3 can be independently moved in the circumferential direction, for example, when the bag nut 3 is connected to a water sprinkler and the cutter 2 holds the hose. Since the bag nut can be rotated with respect to the cutter, it does not interfere with the movement of the twisted hose to return to the normal state by the water flow, and does not loosen the screwed bag nut 3.

[0019]

[Effect of device]

 According to this invention, the following effects can be obtained. That is, since the cutter 2 and the bag nut 3 are integrated with each other, dust and mud do not collect inside the joint, so that the detaching work can be easily performed. For example, by cutting and using the hose between sprinklers, drainage can be facilitated, and sprinkler facilities can be easily moved and removed, contributing to labor saving.
