[0001] The utility model relates to the field of HDPE corrugated pipes, in particular to a HDPE corrugated pipe with a built-in reinforcing rib structure. Background Art

[0002] HDPE double-wall corrugated pipe is a new type of lightweight pipe made of high-density polyethylene. It has the characteristics of light weight, high pressure resistance, good toughness, fast construction and long service life. Its excellent pipe wall structure design greatly reduces the cost compared with pipes with other structures. And because of its convenient and reliable connection, it has been widely used at home and abroad, replacing a large number of concrete pipes and cast iron pipes.

[0003] The prior art has the following problems:

[0004] When using HDPE double-wall corrugated pipe, its corrugated structure has the ability to adapt to installation in uneven grooves, and it can lay the pipe by producing slight deformation itself. However, after deformation, its bending section is the main load-bearing structure, and there is a risk of damage to the bending section after long-term use, which is a deficiency. Utility Model Content

[0007] (II) Technical solution

[0008] In order to solve the above technical problems, the utility model provides a HDPE corrugated pipe with a built-in reinforcing rib structure, comprising a convex section protruding outward and a concave section bending inward, wherein the combined structure of the convex section and the concave section are arranged equidistantly;

[0009] An inner rubber ring is arranged in the clamping groove of the inner wall of the convex pattern section, and a limiting rubber ring is arranged on the outer side of the inner rubber ring;

[0010] The reinforcing mechanism comprises a boss penetrating the opening of the limiting rubber ring, one end of the boss is connected to the inner wall of the inner rubber ring, and spring plates are symmetrically formed on both sides, and two adjacent spring plates are connected by a spring member.

[0011] Preferably, the cross section of the inner rubber ring is a "stepped" structure, and the clamping interval between the limit rubber ring and the convex pattern section matches the cross section of the inner rubber ring.

[0012] Preferably, the inner rubber ring and the limiting rubber ring are both elastic components, and the side wall of the limiting rubber ring is connected to the inclined inner wall of the convex pattern section.

[0013] Preferably, the convex segment is a supporting segment, and the concave segment is a bending segment.

[0014] Preferably, at least four bosses are provided, and correspondingly, two opposite spring plates are connected via a spring member.

[0015] Preferably, the spring element is an elastic component, which deforms synchronously with the combination of the convex groove segment and the concave groove segment as a whole, bends inwards for compression, and expands outwards for stretching.

[0016] The above-mentioned technical scheme of the utility model has the following beneficial technical effects: through the arrangement of the auxiliary reinforcement mechanism in the inner cavity of the pipeline by the cooperation of the limiting rubber ring and the inner rubber ring, when the pipeline is bent, the spring part close to the inward bending position is compressed, and the spring part on its opposite side close to the outward expansion position is stretched, and the spring part located in the middle is used for deformation compensation. The external force of deformation is compensated by the cooperation of the upper, middle and lower spring parts, which solves the problem that only the concave section as the bending section is subjected to force alone, and improves the structural strength of the pipeline.

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0024] like Figure 1-4 As shown, the utility model proposes a HDPE corrugated pipe with a built-in reinforcing rib structure, comprising a convex section 1 protruding outward and a concave section 2 bending inward, and the combined structure of the convex section 1 and the concave section 2 are arranged equidistantly;

[0025] Among them, the convex section 1 is the supporting section, and the concave section 2 is the bending section. When the pipe is slightly deformed, the concave section 2 bends, driving the convex section 1 to close at the position close to the bending axis and to expand at the position far from the bending axis;

[0026] An inner rubber ring 3 is arranged in the clamping groove of the inner wall of the convex pattern section 1, and a limiting rubber ring 4 is arranged outside the inner rubber ring 3;

[0027] The reinforcing mechanism includes a boss 51 penetrating through the opening of the limiting rubber ring 4 , one end of the boss 51 is connected to the inner wall of the inner rubber ring 3 , and spring plates 52 are symmetrically formed on both sides, and two adjacent spring plates 52 are connected by a spring member 53 .

[0028] It should be noted that: an inner rubber ring 3 is embedded in the convex section 1, wherein the cross-section of the inner rubber ring 3 is a "step" structure, the limiting rubber ring 4 and the clamping interval of the convex section 1 match the cross-section of the inner rubber ring 3, and the position of the inner rubber ring 3 is limited by the limiting rubber ring 4 to ensure that it remains in the clamping groove of the convex section 1.

[0029] In this embodiment, the arrangement of the auxiliary reinforcement mechanism in the inner cavity of the pipeline is assisted by the cooperation of the limiting rubber ring 4 and the inner rubber ring 3. In this application, a total of four bosses 51 are arranged, all of which penetrate the opening of the limiting rubber ring 4 and establish a connection with the inner rubber ring 3. Along the flow direction of the medium, the side walls of the bosses 51 are all provided with spring plates 52;

[0030] Taking every three groups of convex sections 1 as an example, no reinforcement mechanism is set at the middle convex section 1, and the two spring plates 52 at the far end are connected by a spring member 53. When the pipeline is bent, the spring member 53 close to the inward bending position is compressed, and the spring member 53 on the opposite side close to the outward expansion position is stretched. The spring member 53 in the middle compensates for the deformation, and the external force of the deformation is compensated by the cooperation of the upper, middle and lower spring members 53, which solves the problem that only the concave section 2 as the bending section is subjected to force alone, thereby improving the structural strength of the pipeline.

[0031] It can be understood that the spring member 53 is an elastic member. Under the action of the deformation external force, it deforms synchronously with the combination of the convex groove segment 1 and the concave groove segment 2, bending inward for compression and expanding outward for stretching.

[0032] It should be added that: the inner rubber ring 3 and the limiting rubber ring 4 are both elastic components. During the deformation of the pipeline, the inner rubber ring 3 and the limiting rubber ring 4 can be deformed accordingly. However, since the side wall of the limiting rubber ring 4 is fixed on the inclined inner wall of the convex groove section 1, the inner rubber ring 3 in the inner cavity is always limited before and after the deformation to prevent it from slipping out of the clamping groove on the inner wall of the convex groove section 1.

[0033] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
