The present invention relates to a rubber ring for a pipe having a rolling prevention function that can improve the airtightness by reducing the defect rate of the fastening by preventing the separation phenomenon caused by the sliding or deformation.

Synthetic resin pipes used as sewage pipes are classified into various structures and functions, but they are generally molded and cut into lengths of about 6 meters, and then connected by various connection methods when buried underground. Synthetic resin pipes have the advantage of being lightweight, easy to handle, and offering various sizes depending on their use, but the shape formed after being buried in internal pressure or soil is deformed or partially vulnerable due to pressure. There was a defect that can not be used for various reasons.

Generally, the corrugated synthetic resin tube (hereinafter referred to as “wrinkle tube”) has an accommodation space formed therein, and its use is very wide because it is light and strong compared to other types of tubes. In order to connect the corrugated pipe, it is provided with a rubber ring as a sealing member which is coupled to the end of the pipe to prevent the leakage of fluid. When the socket and the rubber ring are connected, the rubber ring is inserted into the corrugated pipe and then forcedly inserted. At this time, the rubber ring between the corrugated pipe and the socket is pushed or distorted due to the forced insertion, and the work is sometimes performed again, and it is difficult to know whether the rubber ring is released even after the work is completed. Problems often arise.

As a related art in this regard, the Korean Utility Model Registration No. 20-0382842 (April 25, 2005) stated, “In connecting the ends of a pair of adjacent synthetic resin double wall pipes (1) to each other, a pair of synthetic resin double wall pipes is used.

형상을 갖게 될 수 있다. 또한 도 6에 도시된 바와 같이 상기 측면부(32)의 내부 안쪽에는 돌기가 형성되어 상기 고무링(30)을 소켓(20)의 한쪽에 삽입하고 나서 다른 한쪽에 주름관(10-1)을 삽입할 때 힘을 가하여 강제로 삽입하게 되는데, 이때 주름관(10)과 주름관(10-1)의 충격을 흡수 완화시킴으로써 주름관(10)(10-1)의 파손을 방지할 수 있게 된다. Piping rubber ring 30, 30-1 according to the present invention, as shown in Figures 1 to 4, sealing between the corrugated pipe 10 and the corrugated pipe 10-1 by the socket 20 to seal For sealing, first, a ring-shaped protrusion 11 is formed on the outer circumferential surface of the corrugated pipe 10, 10-1, and the rubber ring 30, 30-1 on the outer circumferential surface of the ring-shaped protrusion 11. The cover part 31 which is a part of the close contact is coupled. At the same time, the side part 32, which is a part of the rubber rings 30 and 30-1, is closely attached to the side wall 12 of the ring-shaped protrusion 11, and the rubber rubber ring 30 and 30- 1) is composed of the cover portion 31 and the side portion 32 as a whole

It has a shape. Specifically, the side portion 32 is provided on both left and right sides of the ring-shaped protrusion 11 as shown in FIG.

It can have a shape. Also, as shown in FIG. 6, a protrusion is formed inside the side part 32 to insert the rubber ring 30 into one side of the socket 20, and then insert the corrugated pipe 10-1 into the other side. When the force is inserted by force, at this time, by absorbing and cushioning the impact of the corrugated pipe 10 and the corrugated pipe 10-1, it is possible to prevent the breakage of the corrugated pipe 10, 10-1.

On the other hand, the rubber ring 30 for the pipe 30, 30-1 according to the present invention, as shown in Figures 2 to 4, the reinforcement having elasticity to be inserted into the side portion 32 to extend in the circumferential direction 33 may include four elastic parts 33-1 and a connecting part 33-2 connecting the elastic parts 33-1 to each other. The reinforcing material 33 may be inserted into both left and right sides or the right side of the side portion 32.

The shape of the reinforcing material 33 is as shown in Fig. 5 (a) of Figure 5 so that the rubber ring 30, 30-1 for the pipe is extended and contracted by the elastic portion 33-1. A plurality of holes 34 are formed in a zigzag shape as shown in FIG. 5 or in a wave shape as shown in FIG. 5B, or in a wavy plate so that rubber can penetrate back and forth during molding of the rubber ring as shown in FIG. It may be selected from the forms that are formed.

The insertion form of the reinforcing material 33 inserted into the side portion 32 of the rubber ring 30, 30-1 for the pipe is shown in Figure 3 and 4, the rubber ring 30 for the pipe The elastic portion 33-1 is inserted into the side portion 32 of the 30-1, and the connecting portion 33-2, which is the remaining portion, has a form in which these shapes are connected to each other in a straight line. desirable. In particular, only four positions are formed in a zigzag shape and the like, and the remaining portions have a form in which the shapes are connected to each other in a straight line so that the elasticity of the rubber rings 30 and 30-1 for piping can be properly maintained. . If a zigzag shape or the like is inserted into the entirety of the side part 32 as the stiffener 33, the elasticity of the rubber pipe rings 30 and 30-1 may be increased, but rather, the side surfaces of the rubber pipe rings may be increased. When a force is applied in the longitudinal direction to the force that can firmly support the rubber ring (30) (30-1) for plumbing may fall.

In addition, the reinforcing material 33 is made of a material that does not corrode, for example, preferably made of metal, plastic, fiber, and the like that does not corrode.

Furthermore, in order to further secure the coupling to the ring-shaped protrusion 11, the rubber rubber rings 30 and 30-1 for the pipes, as shown in FIGS. 6 and 7, are provided with the rubber rubber rings 30 and 30-30. The rubber ring 30 (30-1) by forming the angle (B) formed between the cover portion 31 and the side portion 32 of 1) smaller than the corner angle (A) of the ring-shaped protrusion (11) When the cover portion 31 is coupled to the ring-shaped protrusion 11, the cover portion 31 receives an elastic force in a direction in close contact with the outer diameter of the corrugated pipe 10, 10-1, and the side portion 32 has the ring-shaped protrusion 11. Receiving an elastic force in the direction in close contact with the side wall 12 of the) it is possible to more tightly close to the cover portion 31 and the side portion 32 to the ring-shaped protrusion (11), respectively.

The angle B formed between the cover portion 31 and the side surface portion 32 will be described in detail. Since the corner angle A of the ring-shaped protrusion 11 is formed at a right angle of 90 °, The angle B formed between the cover portion 31 and the side surface portion 32 is preferably in the range of 80 to 85 degrees smaller than this. In this case, when the angle (B) is smaller than 80 °, too much force is required when inserting the rubber ring 30 (30-1) for the pipe into the ring-shaped protrusion (11), and even after the insertion There is a disadvantage that the rubber ring 30, 30-1 for the pipe is easily cracked. On the other hand, when the angle (B) to 85 ° or more, the pipe rubber ring 30, 30-1 can be easily inserted into the ring-shaped protrusion 11, but the elasticity is not suitable for the pipe Rubber rings 30 and 30-1 may not be firmly coupled to the ring-shaped protrusion 11.

The pipe rubber rings 30 and 30-1 formed in this way are firmly coupled to the ring-shaped protrusion 11 formed on the outer circumferential surface of the corrugated pipe 10 and 10-1 to apply a force to the socket 20. When the rubber ring 30 is forcibly inserted, the rubber rings 30 and 30-1 are not pushed or detached and are not damaged, and thus, there is no need for rework. Furthermore, even after insertion, the rubber rings 30 and 30-1 do not need to check whether the rubber rings 30 and 30-1 are not firmly coupled to the ring-shaped protrusions 11 and are separated from each other.
