Description

Technical Field

[0001] This utility model relates to the connection technology of corrugated rainwater and sewage pipes, specifically an adjustable pipe connector for rainwater and sewage pipes. Background Technology

[0002] During the construction process, underground pipelines are usually laid. Roads or buildings need to use rainwater and sewage pipes to deal with drainage work during rainy weather. In order to adapt to the underground soil drainage work next to roads and buildings, corrugated pipes that are easy to assemble, high-strength, and low-cost are usually used.

[0003] For example, the publication (announcement) number: CN219473027U, publication (announcement) date: 2023-08-04, discloses a corrugated pipe connection device; including two tensioners, a graduated steel wire rope and a steel strip; one end of the steel strip has multiple clamping holes with size markings, and the other end is provided with a connecting buckle, and the surface of the steel strip is connected with multiple spaced steel wire rope connecting rings; the connection device of this utility model has the advantages of strong stability, simple structure, easy operation, and high pipeline accuracy.

[0004] The shortcomings of existing technology lie in the fact that while corrugated pipes possess excellent flexibility, and their joints, using socket joints and sealing rubber rings, allow for axial displacement and angular deflection within a certain range in the assembled drainage system, traditional sealing rings are mostly single-piece structures. The sealing process relies on the insertion and assembly of two corrugated pipe sections, followed by pressure application to the sealing ring to achieve a seal. Furthermore, the material of these sealing rings cannot be significantly improved in terms of sealing capacity; therefore, their sealing performance under specific requirements can only be met through structural design. Consequently, the sealing effect of such sealing rings when used in underground corrugated pipe installations needs further improvement. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable pipe connector for rainwater and sewage pipes to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable pipe connector for rainwater and sewage pipes includes a corrugated pipe, with a pipe sleeve and a pipe head respectively provided at both ends of the corrugated pipe, and the pipe head having recessed sections evenly distributed along the axial direction.

[0008] It also includes a sealing ring with a convex ring and two concave rings, wherein the concave rings are embedded in the concave section;

[0009] The inner diameter of the sleeve is provided with a sleeve wall for inserting a convex ring.

[0010] As a further description of the above technical solution: the outer wall of the pipe head is fixedly installed with an annular protrusion for sealing the sleeve port.

[0011] As a further description of the above technical solution: the sleeve is provided with circumferentially arranged sleeve holes.

[0012] As a further description of the above technical solution: the tube head is provided with a head hole that communicates with the sleeve hole.

[0013] As a further description of the above technical solution: the convex ring is provided with a ring hole that connects the sleeve hole and the head hole.

[0014] As a further description of the above technical solution: a plurality of elastic plates are fixedly installed on the sealing ring between adjacent ring holes.

[0015] As a further description of the above technical solution: the elastic plate is provided with a convex plate located in the convex ring.

[0016] As a further description of the above technical solution: concave plates are provided on both sides of the convex plate, which are located in the concave ring.

[0018] As a further description of the above technical solution: an arc plate located in the arc protrusion is fixedly installed on the concave plate.

[0019] In the above technical solution, the adjustable pipe connector for rainwater and sewage pipes provided by this utility model has the following beneficial effects: by putting the sealing ring on the pipe head and then inserting the pipe head into the sleeve wall, the convex ring and the concave rings on both sides form a convex-shaped interception seal. Combined with the sleeve wall and the two concave sections fitting together, the sealing function can be strengthened, the connection position of adjacent corrugated pipes is not easy to leak water, and the shape of the concave-convex combination can also improve the structural strength of the connection position, ensuring the stability of the sealing ring on the corrugated pipe.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 This utility model provides a technical solution, including the following embodiments:

[0029] Example 1

[0030] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment strengthens the connection seal between pipes by utilizing the shape structure based on the existing seals used in rainwater and sewage pipes, specifically the sealing rings 4 installed at both ends of the corrugated pipe 1. By fitting the sealing rings 4 onto the pipe head 3 and then inserting the pipe head 3 into the sleeve wall 21 of the pipe sleeve 2, the convex ring 41 and the concave rings 42 on both sides form a convex-shaped interception seal. Combined with the fitting of the sleeve wall 21 and the two concave sections 31, the sealing function is strengthened, making it less prone to water leakage at the connection point of adjacent corrugated pipes 1. Furthermore, the shape of the convex-concave combination also enhances the structural strength of the connection point, ensuring the stability of the sealing rings 4 on the corrugated pipe 1.

[0031] Specifically, the sealing ring 4 is formed by integrally molding two concave rings 42 and convex rings 41. The concave section 31 is opened on the surface of the tube head 3, so there is a position between the two concave sections 31 relative to its convex position, that is, the surface of the tube head 3 used to fit the convex ring 41.

[0032] Example 2

[0033] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment details the structural connection between adjacent corrugated pipes 1. The convex ring 41 on the outside of the pipe head 3 slides into the end position of the sleeve wall 21 to achieve the insertion and sealing of the pipe head 3 and the sleeve 2. The annular protrusion 32 integrally formed on the outer wall of the pipe head 3 remains in close contact with the sleeve wall 21 after entering it, which facilitates the use of the hard material on the surface of the corrugated pipe 1 to achieve basic protection.

[0034] Secondly, the circumferentially arranged sleeve holes 20 and head holes 30 are connected by bolts, which enables the adjacent bellows 1 to strengthen the stability of the connection position by using bolts, making the bellows 1 less likely to loosen. At the same time, the bolts are also inserted into the ring holes 40, which realizes the tightening of the fitted sealing ring 4, prevents the sealing ring 4 from falling off, and ensures that the sealing work is normal and stable.

[0035] Specifically, the inner walls of the sleeve hole 20 and the head hole 30 are treated for threaded connection, and the corner of the annular protrusion 32 is rounded on one side.

[0036] Furthermore, the multiple holes 40 formed on the convex ring 41 enable the sealing ring 4 to act evenly on the center of the sealing ring 4 when the bolt is tightened.

[0037] Example 3

[0038] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, this embodiment details how the elastic plate 5 inside the sealing ring 4 achieves the anti-torsion function. When circumferential torque occurs between the sleeve 2 and the pipe head 3, either concave ring 42 tends to twist circumferentially under the force. One end of the elastic plate 5 on that side is subjected to the same force, and at this time, the elastic plate 5 shifts circumferentially along the direction parallel to the axis. The middle part of the elastic plate 5 is fastened by the convex ring 41 and remains relatively stationary, so that the opposite end of the elastic plate 5 generates a reverse torque. Thus, the elastic plate 5 acts as a bridge between the two concave rings 42, causing the reverse torque of the other concave ring 42 to be canceled out, thereby reducing the torque that occurs in either the sleeve 2 or the pipe head 3 and ensuring the stability of the connection position.

[0039] Specifically, the convex plate 51 and the integrally formed concave plates 52 on both sides are injection molded into the sealing ring 4, which makes it easier for the two concave plates 52 to transmit torque, and at the same time, it can keep the position of the convex plate 51 stable, which is convenient for it to cooperate with the position of the convex ring 41.

[0040] Furthermore, the closed annular protrusion 32 leaves a gap between the side wall of the sealing ring 4 and the sleeve wall 21, while the arc protrusion 43 integrally formed at the position of the concave ring 42 is used to fill the defect to ensure sealing and blocking.

[0041] Furthermore, the arc plate 53, integrally formed on the concave plate 52, is located inside the arc protrusion 43 and serves to form a skeleton within the arc protrusion 43, strengthening the support of the side wall of the arc protrusion 43 against the sleeve wall 21, making it less likely for sewage to seep into the gaps in the annular protrusion 32 due to the support of the arc protrusion 43.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
