Abstract

The present invention relates to the 'O' ring structure of the coupler used to connect the hose when supplying agricultural water or spraying pesticides.

The 'O' ring structure of the conventional agricultural coupler has a 'O' ring that is crushed when strong water pressure is struck by the 'O' ring made of rubber material, which is sequentially inserted into the ring insertion hole 4 of the connector 3. As the 'O' ring is separated and lost from the insertion hole 5, there is often a problem in which leakage occurs in the agricultural coupler 1.

In this invention, the rubber 'O' ring is inserted into the ring insertion hole of the connector, the insertion part is formed in the center of the rubber 'O' ring, and then the injection washer is molded or the rubber ring is formed first. By inserting the support washer in the insert part of the rear rubber ring, the assembly is very simple, but the 'O' ring is crushed due to the strong water pressure to prevent it from falling off and providing an agricultural coupler without fear of leakage.

Description

O-ring structure of use a coupler for agricultural}

The present invention relates to a coupler used to connect a hose when supplying agricultural water or spraying pesticides, and more specifically, by further improving the 'O' ring structure of Utility Model Registration No. 218587, leakage is very simple and leaks. To provide an agricultural coupler without concern.

Utility Model Registration No. 218587, which was filed by the applicant of the present application, connects the coupler body to one end of the hose and connects the insertion port to the other end of the hose when the hose for supplying agricultural water or pesticides is inserted into the body. The hose is simply connected without leakage.

Looking at the configuration thereof, as shown in Figure 3, in the connecting tube (3) which is a component constituting the body (2) of the agricultural coupler (1),

A ring insertion hole 5 having a diameter larger than that of the insertion hole 4 is formed at the entrance of the connecting tube body 3 on the side where the insertion pipe part 11 of the known insertion hole 10 enters,

'O' ring (6), support washer (7), 'O' ring (8) and spring support washer (9) are inserted into the ring insertion hole (5) in order to be assembled to the fixed tube (13) to be.

However, the structure of the above-mentioned 'O' ring is that the 'O' ring is crushed when strong water pressure is struck by the 'O' ring made of rubber material, which is sequentially inserted into the ring insertion hole 4 of the connector 3. As the 'O' ring is separated and lost from the insertion hole 5, there is often a problem in which leakage occurs in the agricultural coupler 1.

Therefore, in order to solve the above problems, the present invention inserts a rubber material 'O' ring into a ring insertion hole of a connector, and inserts a back washer after forming an insertion part in the center of the rubber material 'O' ring. By molding or inserting the rubber ring first and inserting the support washer into the rubber ring insert, the assembly is very simple but the 'O' ring is crushed due to the strong water pressure, which prevents the leakage and loss. The purpose is to provide an agricultural coupler without.

1 is a cross-sectional view of an agricultural coupler as an embodiment of the present invention.

Figure 2 is an exploded perspective view of the main part as an embodiment of the present invention.

3 is a cross-sectional view of a conventional design.

Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings.

1 is a cross-sectional view of an agricultural coupler as an embodiment of the present invention, Figure 2 is an exploded perspective view of the main portion as an embodiment of the present invention.

As shown in Fig. 1 to 2, the insertion hole (4) in the inlet of the connecting tube (3) on the side of the insertion pipe portion 11 of the insertion port 10 enters the connecting tube (3) of the agricultural coupler (1) Longer diameter of the ring inserting hole (5) is formed in the agricultural coupler 'O' ring (6), support washer (7), 'O' ring (8) and spring support washer (9) In the O 'ring structure,

Insert the 'O' ring 20 into the ring insertion hole 5 having a diameter larger than the insertion hole 4 at the inlet of the connecting pipe 3 with rubber material,

After the insertion part 21 is formed in the center of the rubber material 'O' ring 20, the insert washer 7 is molded or the rubber material 'O' ring 20 is formed first, and then the rubber material is formed. It is a structure to insert the support washer (7) in the insertion portion 21 of the 'O' ring (20).

Referring to Figures 1 and 2 attached to the operation of one embodiment of the present invention configured as described above are as follows.

First, the 'O' ring 20 is inserted into the ring insertion hole 5 having a diameter larger than that of the insertion hole 4 at the inlet of the connector 3 of the agricultural coupler 1 with rubber material, but the rubber material 'O' After forming the insertion part 21 in the center of the ring 20, insert molding the support washer (7), or first forming the rubber 'O' ring 20 and the rubber 'O' ring (20) Insert the washer 7 into the insertion portion 21 of the).

Here, the insertion part 21 is formed at the center of the rubber material 'O' ring 20 in the ring insertion hole 5 of the connecting pipe 3, and then the insert washer 7 is molded or the rubber material ' After forming the O 'ring 20 as a primary, it is possible to select and install the one having inserted the support washer 7 in the insertion portion 21 of the rubber material' O 'ring 20.

Thereafter, the spring bearing washer 9, the action spring 12 is inserted sequentially.

Therefore, after inserting the center portion of the rubber material 'O' ring in the ring insertion hole of the connector body, insert molding the support washer or forming the rubber material 'O' ring first and then By inserting the support washer in the insertion part, the assembly is very simple, but due to the strong water pressure, the 'O' ring can be crushed and prevented from being lost due to leakage.

As described above, the present invention inserts a rubber material 'O' ring into the ring insertion hole of the connector, inserts the backing washer or forms a rubber ring after forming an insert in the center of the rubber material 'O' ring. By forming the car and inserting the support washer into the insert of the rubber ring, it is very simple to assemble and prevents the 'O' ring from being distorted and lost due to the strong water pressure, thereby providing an agricultural coupler without fear of leakage. It has an effect.
