Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, and more specifically, to a corrugated pipe with a support and protection component. Background Technology

[0002] HDPE double-wall corrugated pipe, or simply PE corrugated pipe, has evolved from a single product type to a complete product series after more than ten years of development and improvement. Double-wall corrugated pipe is a new type of lightweight pipe made from high-density polyethylene (HDPE). It features light weight, high pressure resistance, good toughness, fast construction, and long service life. Its superior pipe wall structure design significantly reduces costs compared to other pipe structures. Furthermore, due to its convenient and reliable connection, it is widely used both domestically and internationally. Corrugated pipes can be made of steel or plastic, such as HDPE, polypropylene, polyethylene, and nylon. Some can also be coated or lined. Based on the constituent materials, they can be divided into metal corrugated pipes and non-metal corrugated pipes; based on the structure, they can be divided into single-layer and multi-layer; and based on the application, they can be divided into corrugated pipes for protecting electrical wires and organizing wiring, corrugated pipes for pressure measurement, etc.

[0003] Among them, the patent with publication number CN217993711U discloses a corrugated pipe with a support and protection component, including a corrugated pipe body, the corrugated pipe body including a base layer, the bottom of the base layer is sprayed with an acid and alkali resistant layer, the top of the base layer is bonded with a fireproof layer by an adhesive, the top of the fireproof layer is bonded with a corrosion resistant layer by an adhesive, the corrosion resistant layer includes a first corrosion resistant layer, the top of the first corrosion resistant layer is bonded with a second corrosion resistant layer by an adhesive, the base layer is made of high-density polyethylene, the surface of the base layer is sprayed with an antibacterial agent, the acid and alkali resistant layer is made of fluororubber, and its inner surface is sprayed with Teflon coating liquid; When in use, this structure, through the combined use of a base layer, an acid and alkali resistant layer, a fireproof layer, a corrosion resistant layer, a first corrosion resistant layer, and a second corrosion resistant layer, enables the corrugated pipe body to have good strength, fire resistance, and corrosion resistance, and is also easy to handle in an environmentally friendly manner. However, the structure itself is not strong enough and is easily deformed by external forces, causing damage to its internal wiring harness. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a corrugated pipe with supporting and protective components, which aims to solve the problems mentioned in the background art.

[0005] The present invention provides the following technical solution: a corrugated pipe with a support and protection component, comprising a support sleeve, wherein the support sleeve is provided with the support and protection component; The support and protection assembly includes a support tube body disposed on the outside of the support sleeve, and a corrugated outer sleeve is provided on the outside of the support tube body; Several mounting cavities are formed between the corrugated jacket and the support tube, and each mounting cavity is provided with a relief strip for support. The top vertical cross-section of the relief strip is arc-shaped, and several pressure relief holes are opened through the relief strip. The top of the relief strip extends to the inner wall of the corrugated jacket.

[0006] As can be seen, in the above technical solution, when the supporting tube and the corrugated jacket are deformed by external force, the corrugated jacket deforms first and applies pressure to the damping strip. The damping strip deforms under force and squeezes the pressure relief hole, so that the damping strip itself has a large deformable range, making it easy to absorb energy and avoid damage to the wire harness by external force. Optionally, in one possible implementation, a gasket is provided at the bottom of the inner wall of the mounting cavity, the gasket is fixed to the surface of the support sleeve, a support rib is fixedly provided on the gasket, a slide bar is fixedly provided on the support rib, the slide bar has an arc-shaped vertical cross-section and extends to the bottom of the reduction bar and slides in connection with the reduction bar, and an inner rib is fixedly provided inside the support sleeve, the inner rib has a spiral-shaped vertical cross-section; As can be seen, in the above technical solution, the inner rib first comes into contact with the wire harness to provide a wrapping protection for the wire harness, while increasing the friction between the wire harness and the support sleeve. This makes it easier for the corrugated pipe to bend the wire harness when it is bent, which is convenient for workers to carry out wiring operations.

[0007] The technical effects and advantages of this utility model are as follows: With the addition of a support and protection component, the inner rib first contacts the wire harness to provide a wrapping protection, while also increasing the friction between the wire harness and the support sleeve. This makes it easier for the corrugated pipe to bend the wire harness when it is bent, which is convenient for workers to carry out wiring operations. When the support tube and the corrugated jacket are deformed by external forces, the corrugated jacket deforms first and applies pressure to the damping strip. The damping strip deforms under force and squeezes the pressure relief hole, so that the damping strip itself has a large deformable range, making it easy to absorb energy and avoid damage to the wire harness by external forces.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] As attached Figure 1-4 The corrugated pipe shown has a support and protection component. The support and protection component on the support sleeve 1 protects the wire harness by first contacting the inner rib 10, which increases the friction between the wire harness and the support sleeve 1. This makes it easier for the corrugated pipe to bend the wire harness when it is bent, which is convenient for the workers to do the wiring operation. At the same time, when the support pipe body 2 and the corrugated sleeve 3 are deformed by external force, the corrugated sleeve 3 deforms first and applies pressure to the damping strip 7. The damping strip 7 deforms under force and squeezes the pressure relief hole 9, so that the damping strip 7 has a large deformation range, which makes it easy to absorb energy and avoid damage to the wire harness by external force. The specific structure of the component is as follows. The support and protection assembly includes a support tube 2 disposed on the outside of the support sleeve 1, and a corrugated outer sleeve 3 is fitted on the outside of the support tube 2; Several mounting cavities 4 are formed between the corrugated jacket 3 and the support tube 2, and each mounting cavity 4 is provided with a relief strip 7 for support. The top vertical cross-section of the relief strip 7 is arc-shaped, and several pressure relief holes 9 are opened through the relief strip 7. The top of the relief strip 7 extends to the inner wall of the corrugated jacket 3.

[0016] A washer 5 is provided at the bottom of the inner wall of the mounting cavity 4. The washer 5 is fixed to the surface of the support sleeve 1. A support rib 6 is fixedly provided on the washer 5. A slide 8 is fixedly provided on the support rib 6. The vertical cross-section of the slide 8 is arc-shaped, and the slide 8 extends to the bottom of the reduction strip 7 and slides and connects with the reduction strip 7. An inner rib 10 is fixedly provided inside the support sleeve 1. The vertical cross-section of the inner rib 10 is spiral-shaped.

[0017] When using the above structure, the staff will put the device on the wire harness that needs to be protected. The inner rib 10 will first come into contact with the wire harness to wrap and protect it. At the same time, it will increase the friction between the wire harness and the support sleeve 1, making it easier for the corrugated pipe to bend the wire harness when it is bent, which will facilitate the wiring operation of the staff. When the support tube 2 and the corrugated jacket 3 are deformed by external force, the corrugated jacket 3 deforms first and applies pressure to the damping strip 7. The damping strip 7 deforms under force and squeezes the pressure relief hole 9, so that the damping strip 7 has a large deformable range, making it easy to absorb energy and avoid damage to the wire harness by external force.

[0018] Unlike existing technologies, this application discloses a corrugated pipe with supporting and protective components. The inner rib 10 first contacts the wire harness to provide a wrapping protection, while increasing the friction between the wire harness and the support sleeve 1. This makes it easier for the corrugated pipe to bend the wire harness when bent, facilitating wiring operations. When the support pipe body 2 and the corrugated outer sleeve 3 are deformed by external forces, the corrugated outer sleeve 3 deforms first and applies pressure to the damping strip 7. The damping strip 7 deforms under force and squeezes the pressure relief hole 9, giving the damping strip 7 a large deformable range, making it easy to absorb energy and preventing external forces from damaging the wire harness.

[0019] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
