Description

Technical Field

[0001] The utility model relates to the technical field of double-wall corrugated pipes, in particular to a high-sealability connection structure of double-wall corrugated pipes. Background Art

[0002] Double-wall corrugated pipe is a new type of pipe with an annular outer wall and a smooth inner wall. After more than ten years of development and improvement, it has developed from a single variety to a complete product series, and its production process and application technology are very mature.

[0003] Traditional double-walled corrugated pipes are usually connected using rubber rings. The rubber ring is put on the outside of one end of the double-walled corrugated pipe, and then inserted into another double-walled corrugated pipe and sealed with the rubber ring. However, due to the general support of the double-walled corrugated pipe, the sealing performance is poor. When transporting water, water can easily seep out from the connection of the double-walled corrugated pipe. Utility Model Content

[0004] In order to solve the above technical deficiencies, the utility model provides a double-wall corrugated pipe high-sealability connection structure with good sealing effect.

[0005] The utility model discloses a high-sealability connection structure of a double-walled corrugated pipe, comprising a No. 1 double-walled corrugated pipe, a No. 2 double-walled corrugated pipe, a rubber ring, a support ring and a rubber sleeve. The inner wall of the No. 1 double-walled corrugated pipe is a smooth inner wall, and the outer wall of the No. 1 double-walled corrugated pipe presents an annular corrugated structure. A rubber ring is sleeved at a recessed portion of the outer wall of one end of the No. 1 double-walled corrugated pipe, and a support ring is embedded on the inner side of the No. 1 double-walled corrugated pipe at this end. One end of the rubber sleeve is connected to the rubber ring, and the other end of the rubber sleeve is connected to the support ring after bypassing the end of the No. 1 double-walled corrugated pipe. The thickness of the rubber sleeve gradually increases along the rubber ring toward the support ring. The No. 1 double-walled corrugated pipe is inserted into the No. 2 double-walled corrugated pipe, and the rubber ring and the rubber sleeve on the outer side of the No. 1 double-walled corrugated pipe are both pressed against the inner wall of the No. 2 double-walled corrugated pipe.

[0006] The principle of the above structure is that when the No. 1 double-wall corrugated pipe is inserted into the No. 2 double-wall corrugated pipe, the rubber sleeve on the outside of the No. 1 double-wall corrugated pipe and the inner wall of the No. 2 double-wall corrugated pipe pulls the rubber sleeve by friction, so that the thicker part of the rubber sleeve is gradually embedded between the No. 1 double-wall corrugated pipe and the No. 2 double-wall corrugated pipe. At the same time, the rubber sleeve pulls the support ring to move outward, and the support ring provides effective support from the inside of the No. 1 double-wall corrugated pipe, so that the rubber sleeve and rubber ring between the No. 1 double-wall corrugated pipe and the No. 2 double-wall corrugated pipe are pressed more tightly, thereby improving the sealing effect.

[0007] In order to facilitate the movement of the rubber sleeve and the support ring, a lubricating layer is coated on the side of the rubber sleeve that contacts the No. 1 double-walled corrugated pipe. The lubricating layer reduces the friction between the rubber sleeve and the No. 1 double-walled corrugated pipe. During the movement of the rubber sleeve, the lubricating layer on it will also remain on the inner wall of the No. 1 double-walled corrugated pipe, reducing the friction between the support ring and the inner wall of the No. 1 double-walled corrugated pipe, which is beneficial to the movement of the support ring.

[0008] The utility model obtains a high-sealing connection structure for double-walled corrugated pipes, and its beneficial effect is that when the No. 1 double-walled corrugated pipe is inserted into the No. 2 double-walled corrugated pipe, the thicker part of the rubber sleeve will gradually embed between the No. 1 double-walled corrugated pipe and the No. 2 double-walled corrugated pipe, and at the same time, the rubber sleeve pulls the support ring to move outward, thereby providing effective support. Under the double combination, the rubber sleeve and the rubber ring between the No. 1 double-walled corrugated pipe and the No. 2 double-walled corrugated pipe are pressed more tightly, and the sealing effect is good.

[0011] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0012] Embodiment 1:

[0013] like Figure 1 , 2 As shown, the utility model discloses a high-sealability connection structure of a double-walled corrugated pipe, comprising a No. 1 double-walled corrugated pipe 1, a No. 2 double-walled corrugated pipe 2, a rubber ring 3, a support ring 5, and a rubber sleeve 4. The inner wall of the No. 1 double-walled corrugated pipe 1 is a smooth inner wall, and the outer wall of the No. 1 double-walled corrugated pipe 1 presents an annular corrugated structure. A rubber ring 3 is sleeved at the outer wall recess of one end of the No. 1 double-walled corrugated pipe 1, and a support ring 5 is embedded on the inner side of the No. 1 double-walled corrugated pipe 1 at this end. One end of the rubber sleeve 4 is connected to the rubber ring 3, and the other end of the rubber sleeve 4 is connected to the support ring 5 after bypassing the end of the No. 1 double-walled corrugated pipe 1. The thickness of the rubber sleeve 4 gradually increases along the rubber ring 3 toward the support ring 5. The No. 1 double-walled corrugated pipe 1 is inserted into the No. 2 double-walled corrugated pipe 2, and the rubber ring 3 and the rubber sleeve 4 on the outer side of the No. 1 double-walled corrugated pipe 1 are both pressed against the inner wall of the No. 2 double-walled corrugated pipe 2.

[0014] The principle of the above structure is that when the No. 1 double-wall corrugated pipe 1 is inserted into the No. 2 double-wall corrugated pipe 2, the rubber sleeve 4 on the outside of the No. 1 double-wall corrugated pipe 1 and the inner wall of the No. 2 double-wall corrugated pipe 2 pull the rubber sleeve 4 by relying on the friction force, so that the thicker part of the rubber sleeve 4 is gradually embedded between the No. 1 double-wall corrugated pipe 1 and the No. 2 double-wall corrugated pipe 2, and at the same time, the rubber sleeve 4 pulls the support ring 5 to move outward, and the support ring 5 provides effective support from the inside of the No. 1 double-wall corrugated pipe 1, so that the rubber sleeve 4 and the rubber ring 3 between the No. 1 double-wall corrugated pipe 1 and the No. 2 double-wall corrugated pipe 2 are pressed more tightly, so that the sealing effect is good.

[0015] In order to facilitate the movement of the rubber sleeve 4 and the support ring 5, a lubricating layer is coated on the side of the rubber sleeve 4 that contacts the No. 1 double-wall corrugated pipe 1. The lubricating layer reduces the friction between the rubber sleeve 4 and the No. 1 double-wall corrugated pipe 1. During the movement of the rubber sleeve 4, the lubricating layer on it remains on the inner wall of the No. 1 double-wall corrugated pipe 1, reducing the friction between the support ring 5 and the inner wall of the No. 1 double-wall corrugated pipe 1, which is beneficial to the movement of the support ring 5.
