Description

Technical Field

[0001] This utility model relates to the field of installation spiral wound pipe technology, specifically a pressure-resistant and leak-proof spiral wound pipe. Background Technology

[0002] Spiral wound pipe, also known as hot-wound high-density polyethylene (HDPE) spiral wound structured wall pipe, is a special structural wall pipe with high resistance to external pressure. It is made of high-density polyethylene resin as the main raw material and uses a hot-wound spiral wound process. It is supported by polypropylene single-wall corrugated pipe. It has been widely used in urban municipal buried drainage, sewage pipelines, cable and optical cable sheathing pipeline systems, etc.

[0003] Currently, when assembling spiral wound tubes, multiple fixing bolts and connecting discs are required to secure the two spiral wound tubes together. The installation process is very cumbersome. Furthermore, when the spiral wound tubes are subjected to high pressure inside, the connection points are easily damaged due to the fixed connection between the tubes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pressure-resistant and leak-proof spiral wound tube, which has the advantages of convenient positioning and pressure relief, avoiding the problems of cumbersome positioning and damage under high pressure.

[0005] To achieve convenient positioning and pressure relief, this utility model provides the following technical solution:

[0006] A pressure-resistant, leak-proof spiral wound tube includes a fixing frame, a left connecting tube, and a right connecting tube. A fixing component is installed on the side wall of the fixing frame for fixing the left and right connecting tubes. A snap-fit ​​component is installed on the side wall of the right connecting tube for snapping the left and right connecting tubes together. The tube also includes:

[0007] The snap-fit ​​assembly includes a first connecting ring, which is fixedly installed on the side wall of the left connecting pipe. A second connecting ring is fixedly connected to the end of the right connecting pipe. A slot is provided on the side wall of the first connecting ring. A retaining ring is fixedly connected to the end of the second connecting ring, and the retaining ring can extend into the inner cavity of the slot. A first sealing ring is fixedly connected to both sides of the retaining ring. A second sealing ring is fixedly connected to the side wall of the second connecting ring, and the first connecting ring can extend into the inner cavity of the second sealing ring.

[0008] According to some embodiments, a locking block is slidably connected to the inner wall of the retaining ring, and a first spring is fixedly connected between the locking block and the inner wall of the retaining ring. A square groove is opened on the inner wall of the retaining groove, and the locking block can extend into the inner cavity of the square groove. Multiple sets of locking blocks and square grooves are provided, corresponding one to one.

[0009] According to some embodiments, the fixing assembly includes a bidirectional threaded rod, which is rotatably mounted on the side wall of the fixing frame. Both sides of the bidirectional threaded rod are threaded with fixing plates, and the side walls of the bidirectional threaded rod are threaded with nuts. An elastic component is fixedly connected between the fixing frames.

[0010] According to some embodiments, the elastic component includes a sleeve, which is fixedly installed on the side wall of the fixing frame. A sliding column is slidably connected to the inner wall of the sleeve, and the end of the sliding column is fixedly connected to the fixing frame. A second spring is fixedly connected between the sliding column and the sleeve.

[0011] Beneficial effects

[0012] This utility model provides a pressure-resistant and leak-proof spiral tube, which has the following beneficial effects:

[0013] (1) The pressure-resistant and leak-proof spiral tube inserts the retaining ring into the groove cavity of the first connecting ring side wall, and then rotates the retaining ring. When the retaining block rotates to the square groove position, under the rebound force of the first spring, the retaining block extends into the square groove cavity, completing the positioning of the retaining ring and the groove. The first sealing ring is located in the groove cavity, and the first connecting ring extends into the second sealing ring cavity, thereby achieving the sealing effect.

[0014] (2) The pressure-resistant and leak-proof spiral tube utilizes the threaded connection between the bidirectional threaded rod and the fixed plate to move the fixed plate towards the middle, thereby fixing the left connecting tube and the right connecting tube respectively. When the left connecting tube and the right connecting tube are subjected to a large pressure impact, the retaining ring can slide in the inner cavity of the retaining groove, thereby playing a role in relieving pressure. Furthermore, the elastic component restricts the left connecting tube and the right connecting tube from sliding relative to each other at a specific position, preventing them from directly detaching.

[0021] 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.

[0022] Reference Figures 1-5 A pressure-resistant and leak-proof spiral wound tube includes a fixing frame 1, a left connecting tube 101, and a right connecting tube 102. A fixing component 2 is installed on the side wall of the fixing frame 1 to fix the left connecting tube 101 and the right connecting tube 102. A snap-fit ​​component 3 is installed on the side wall of the right connecting tube 102 to snap the left connecting tube 101 and the right connecting tube 102. The tube also includes:

[0023] The snap-fit ​​assembly 3 includes a first connecting ring 301, which is fixedly installed on the side wall of the left connecting pipe 101. A second connecting ring 302 is fixedly connected to the end of the right connecting pipe 102. A slot 303 is provided on the side wall of the first connecting ring 301. A retaining ring 304 is fixedly connected to the end of the second connecting ring 302, and the retaining ring 304 can extend into the inner cavity of the slot 303. A first sealing ring 305 is fixedly connected to both sides of the retaining ring 304. A second sealing ring 306 is fixedly connected to the side wall of the second connecting ring 302, and the first connecting ring 301 can extend into the inner cavity of the second sealing ring 306.

[0024] A retaining block 307 is slidably connected to the inner wall of the retaining ring 304, and a first spring 308 is fixedly connected between the retaining block 307 and the inner wall of the retaining ring 304.

[0025] The inner wall of the card slot 303 is provided with a square groove 309, and the card block 307 can extend into the inner cavity of the square groove 309. Multiple sets of card blocks 307 and square grooves 309 are provided, corresponding one to one.

[0026] It should be noted that: pressing the locking block 307 extends it into the inner cavity of the retaining ring 304, where the first spring 308 is compressed, generating a rebound force. The retaining ring 304 can then be inserted into the inner cavity of the retaining groove 303 on the side wall of the first connecting ring 301. Then, rotating the retaining ring 304, when the locking block 307 rotates to the position of the square groove 309, under the rebound force of the first spring 308, the locking block 307 extends into the inner cavity of the square groove 309, completing the positioning of the retaining ring 304 and the retaining groove 303. The first sealing ring 305 is located in the inner cavity of the groove 303, and the first connecting ring 301 extends into the inner cavity of the second sealing ring 306, thereby achieving a sealing effect. The left connecting pipe 101 and the right connecting pipe 102 are then fixed by the fixing component 2. When the left connecting pipe 101 and the right connecting pipe 102 are subjected to greater pressure, the retaining ring 304 can slide in the inner cavity of the groove 303, thereby playing a role in relieving pressure and preventing the left connecting pipe 101 and the right connecting pipe 102 from being fixed, which would cause damage to their connection.

[0027] Reference Figures 1-5 The fixing component 2 includes a bidirectional threaded rod 201, which is rotatably mounted on the side wall of the fixing frame 1. Both sides of the bidirectional threaded rod 201 are threadedly connected to fixing plates 202.

[0028] The side wall of the bidirectional threaded rod 201 is threaded with a nut 203, and the fixing brackets 1 are fixedly connected with an elastic component 204;

[0029] It should be noted that: the left connecting pipe 101 and the right connecting pipe 102 are positioned and installed through the first connecting ring 301 and the second connecting ring 302. The rotatable bidirectional threaded rod 201, through the threaded connection between the bidirectional threaded rod 201 and the fixing plate 202, allows the fixing plate 202 to move towards the center, thereby fixing the left connecting pipe 101 and the right connecting pipe 102 respectively. The nut 203 is used to fix the bidirectional threaded rod 201, and the fixing brackets 1 are fixedly connected with elastic components 204, so that the left connecting pipe 101 and the right connecting pipe 102 can slide relative to each other at a specific position, which plays a role in relieving pressure.

[0030] Reference Figures 1-5 The elastic component 204 includes a sleeve 4, which is fixedly installed on the side wall of the fixed frame 1, and a sliding column 401 is slidably connected to the inner wall of the sleeve 4.

[0031] The end of the sliding column 401 is fixedly connected to the fixed frame 1, and a second spring 402 is fixedly connected between the sliding column 401 and the sleeve 4.

[0032] It should be noted that the sleeve 4 and the sliding column 401 are connected by the second spring 402. The sliding column 401 can slide inside the sleeve 4, compressing or stretching the second spring 402 to generate a rebound force. Without the action of external force, the sleeve 4 and the sliding column 401 can return to their original positions under the rebound force of the second spring 402.

[0033] Operation method: Press the locking block 307 to extend it into the inner cavity of the retaining ring 304. The first spring 308 is compressed and generates a rebound force. Then, the retaining ring 304 can be inserted into the inner cavity of the retaining groove 303 on the side wall of the first connecting ring 301. Then rotate the retaining ring 304. When the locking block 307 rotates to the position of the square groove 309, under the action of the rebound force of the first spring 308, the locking block 307 extends into the inner cavity of the square groove 309, completing the positioning of the retaining ring 304 and the retaining groove 303. The first sealing ring 305 is located in the inner cavity of the retaining groove 303, and the first connecting ring 301 extends into the inner cavity of the second sealing ring 306, thereby achieving a sealing effect.

[0034] The rotatable bidirectional threaded rod 201, through the threaded connection between the bidirectional threaded rod 201 and the fixing plate 202, allows the fixing plate 202 to move towards the center, thereby fixing the left connecting pipe 101 and the right connecting pipe 102 respectively. The nut 203 is used to fix the bidirectional threaded rod 201. When the left connecting pipe 101 and the right connecting pipe 102 are subjected to greater pressure, the retaining ring 304 can slide in the cavity of the retaining groove 303, thereby playing a role in relieving pressure and preventing the left connecting pipe 101 and the right connecting pipe 102 from being fixed, which would cause damage to their connection. The elastic component 204 allows the left connecting pipe 101 and the right connecting pipe 102 to slide relative to each other at a specific position, preventing them from directly detaching.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
