Description

Technical Field

[0001] This utility model relates to the field of double-wall corrugated pipe technology, specifically a double-wall corrugated pipe that is easy to adjust. Background Technology

[0002] Double-wall corrugated pipe is a new type of pipe with a ring-shaped outer wall and a smooth inner wall. HDPE double-wall corrugated pipe, made of HDPE, can handle a larger flow rate than other pipes of the same diameter. In other words, for the same flow rate requirement, HDPE double-wall corrugated pipe with a relatively smaller diameter can be used, making it widely applicable.

[0003] However, when connecting double-wall corrugated pipes on the market, one end is usually fitted with a rubber sealing ring and then directly snapped together. The connection position can only maintain a straight line, and the degree of deformation is small. It is difficult to adjust the position where bending is required during laying, and forced bending can easily damage the pipe and cause water leakage. Utility Model Content

[0004] This utility model provides an easily adjustable double-wall corrugated pipe, which can effectively solve the problems mentioned in the background art, where double-wall corrugated pipes are usually connected by directly snapping a rubber sealing ring onto one end, and the connection position can only maintain a straight line with little deformation. It is difficult to adjust the position where bending is required during laying, and forced bending can easily damage the pipe and cause water leakage.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a double-walled corrugated pipe that is easy to adjust, comprising a corrugated pipe cylinder, wherein a connecting adjustment assembly is provided at the end of the corrugated pipe cylinder, the connecting adjustment assembly comprising a multi-hole end ring, a metal flexible hose, a connecting ring, a connecting stud, a connecting nut, an inner rotating cylinder, a rotating ball, a lead screw, and an internally threaded pipe;

[0006] Both ends of the corrugated tube are fixedly fitted with perforated end rings. A metal flexible tube is provided on one side of the perforated end ring. Both ends of the metal flexible tube are welded with connecting rings. Connecting studs are uniformly welded to the outside of the connecting rings. A connecting nut is threadedly fitted into the middle of the connecting stud.

[0007] Two opposing connecting rings are uniformly welded with inner rotating cylinders. Rotating balls are rotatably embedded inside the inner rotating cylinders. A lead screw is welded to one end of each rotating ball. Two lead screws located on the same straight line are respectively threaded to both ends of the internally threaded tube.

[0008] According to the above technical solution, the inner diameters of the porous end ring and the connecting ring are equal, and the end faces of the porous end ring and the connecting ring are in contact.

[0009] According to the above technical solution, the internally threaded tube is a hexagonal prism with a threaded hole in the middle, and the threads at both ends of the internally threaded tube have opposite directions.

[0010] According to the above technical solution, a connection protection component is installed on the outer side, and the connection protection component includes an outer protective tube, a drying ring, an inner protective tube, a sealing groove, and a sealing ring;

[0011] An outer protective tube is fixedly sleeved on the outside of the metal hose. A drying ring is sleeved inside the outer protective tube at the gap of the metal hose. An inner protective tube is embedded in the inside of the metal hose. A sealing groove is opened on the side of the connecting ring away from the metal hose, and a sealing ring is embedded inside the sealing groove.

[0012] According to the above technical solution, the inner side of the inner protective tube and the inner side of the corrugated tube are aligned, and the cross-sectional edge of the metal hose is corrugated.

[0013] According to the above technical solution, the drying ring is an annular hollow cloth bag, and the inside of the drying ring is filled with desiccant.

[0014] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use;

[0015] 1. Equipped with a connection adjustment component, the connecting ring of the metal flexible hose is brought close to the multi-hole end ring of the corrugated pipe. The connecting stud passes through the round hole of the multi-hole end ring, and the connecting nut is rotated to fix it. The internal threaded pipe is rotated to adjust the distance between the screws at both ends of the internal threaded pipe. The adjustment range of each internal threaded pipe is different, which causes the rotating ball at the end of the screw to rotate at different ranges in the inner rotating cylinder. The metal flexible hose bends, completing the operation of adjusting the angle of the double-wall corrugated pipe. This makes the laying of the double-wall corrugated pipe more convenient and prevents the double-wall corrugated pipe from breaking due to forced bending, greatly improving convenience.

[0016] 2. Equipped with connection protection components, the sealing ring in the sealing groove is compressed and deformed, resulting in a better sealing effect at the connection between the porous end ring and the connecting ring, preventing leakage. The outer protective tube and drying ring on the outside of the metal hose can effectively protect the outside of the metal hose, keeping it in a dry and sealed environment, slowing down corrosion, and effectively extending the service life of the metal hose. The double-wall corrugated pipe after laying and connecting is safer and more reliable to use. Attached Figure Description

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] Example: Figure 1-4 As shown, this utility model provides a technical solution for an easily adjustable double-walled corrugated pipe, including a corrugated pipe cylinder 1. A connecting adjustment component 2 is provided at the end of the corrugated pipe cylinder 1. The connecting adjustment component 2 includes a multi-hole end ring 201, a metal flexible hose 202, a connecting ring 203, a connecting stud 204, a connecting nut 205, an inner rotating cylinder 206, a rotating ball 207, a lead screw 208, and an internally threaded pipe 209.

[0028] Both ends of the corrugated pipe 1 are fixedly fitted with perforated end rings 201. A metal flexible hose 202 is provided on one side of the perforated end ring 201. Both ends of the metal flexible hose 202 are welded with connecting rings 203. The inner diameters of the perforated end ring 201 and the connecting ring 203 are equal. The end faces of the perforated end ring 201 and the connecting ring 203 are in contact, which facilitates the combination and connection of the perforated end ring 201 and the connecting ring 203. Connecting studs 204 are uniformly welded to the outer side of the connecting ring 203. A connecting nut 205 is threadedly fitted into the middle of the connecting stud 204.

[0029] Two opposing connecting rings 203 have an inner rotating cylinder 206 evenly welded to their end faces. The inner rotating cylinder 206 has a rotating ball 207 embedded inside. One end of the rotating ball 207 is welded with a lead screw 208. The two lead screws 208 located on the same straight line are respectively connected to the two ends of the internally threaded tube 209 by threads. The internally threaded tube 209 is a hexagonal prism with a threaded hole in the middle. The threads at both ends of the internally threaded tube 209 have opposite directions, which makes it easy to pull the lead screws 208 away from or closer to each other while rotating the internally threaded tube 209.

[0030] A connection protection component 3 is installed on the outside. The connection protection component 3 includes an outer protective tube 301, a drying ring 302, an inner protective tube 303, a sealing groove 304, and a sealing ring 305.

[0031] An outer protective tube 301 is fixedly sleeved on the outside of the metal hose 202. A desiccant ring 302 is sleeved inside the outer protective tube 301 at the gap of the metal hose 202. The desiccant ring 302 is an annular hollow cloth bag filled with desiccant to keep the metal hose 202 and the outer protective tube 301 dry and prevent the metal hose 202 from rusting and corroding. An inner protective tube 303 is embedded in the inside of the metal hose 202. The inside of the inner protective tube 303 is aligned with the inside of the corrugated tube 1. The cross-sectional edge of the metal hose 202 is corrugated to facilitate the passage of liquid through the inside of the inner protective tube 303 and the inside of the corrugated tube 1. A sealing groove 304 is opened on the side of the connecting ring 203 away from the metal hose 202. A sealing ring 305 is embedded in the sealing groove 304.

[0032] The working principle and usage process of this utility model are as follows: When it is necessary to connect double-wall corrugated pipes, take the metal hose 202, bring the connecting ring 203 of the metal hose 202 close to the multi-hole end ring 201 of the corrugated pipe cylinder 1, pass the connecting stud 204 through the round hole of the multi-hole end ring 201, and rotate the connecting nut 205 to fix it, thus completing the connection operation. After connection, rotate the internal threaded pipe 209 and adjust the distance between the screws 208 at both ends of the internal threaded pipe 209. Continue to adjust the remaining internal threaded pipes 209. The adjustment range of each internal threaded pipe 209 is different, which makes the rotation range of the rotating ball 207 at the end of the screw 208 in the inner rotating cylinder 206 different. The metal hose 202 bends, thus completing the operation of adjusting the angle of the double-wall corrugated pipe. This makes the double-wall corrugated pipe more convenient to lay and prevents the double-wall corrugated pipe from breaking due to forced bending, greatly improving convenience.

[0033] During the installation of the metal flexible hose 202, the porous end ring 201 and the connecting ring 203 are tightly pressed together, and the sealing ring 305 in the sealing groove 304 is deformed by compression, which makes the sealing effect at the connection between the porous end ring 201 and the connecting ring 203 better and prevents leakage. The outer protective tube 301 and the drying ring 302 on the outside of the metal flexible hose 202 can effectively protect the outside of the metal flexible hose 202, keep the outside of the metal flexible hose 202 in a dry and closed environment, slow down its corrosion, and effectively extend the service life of the metal flexible hose 202. The double-wall corrugated pipe after laying and connecting is safer and more reliable.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
