Description

Technical Field

[0001] This utility model relates to the field of PE corrugated pipe installation technology, specifically a PE corrugated pipe with high sealing performance. Background Technology

[0002] PE corrugated pipe, also known as polyethylene corrugated pipe, is a plastic protective sleeve made of extruded polyethylene material. It is called corrugated pipe because its inner and outer ring corrugations are used to protect cables from damage. It has good wear resistance and corrosion resistance. Because PE material is more resistant to corrosion, wear and aging, and is environmentally friendly, PE corrugated pipe is also commonly used as a branch pipe for rainwater and sewage.

[0003] Currently, the common practice for using bellows is to install flange interfaces on the outside of the bellows and then connect the bellows together through the flange connections. However, for bellows that have been in long-term use, this method does not provide a high level of sealing and only serves to fix the connection. Furthermore, the flange interfaces need to be aligned with the threaded holes, making the installation and fixing process rather cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a PE corrugated pipe with high sealing performance, which has the advantages of sealing and easy fixing, avoiding the problems of poor sealing performance and cumbersome installation of flange fixing.

[0005] To achieve both sealing and ease of fixation, this utility model provides the following technical solution:

[0006] A high-sealing PE corrugated pipe includes a left connecting pipe and a right connecting pipe, wherein a first connecting ring is fixedly connected to the side wall of the left connecting pipe, and a second connecting ring is fixedly connected to the side wall of the right connecting pipe, and further includes:

[0007] The first connecting ring has a slot on its side wall, and the second connecting ring has a retaining ring fixedly connected to its side wall, with the retaining ring extending into the inner cavity of the slot. The top of both the first and second connecting rings is fixedly connected to a circular ring. The side walls of the first and second connecting rings are engaged with fixing rings, and there are two sets of fixing rings. The inner wall of the fixing ring is fixedly connected with a rubber block, which is engaged between the circular rings. The side wall of the fixing ring is threaded with a fixing bolt, which is used to fix the two sets of fixing rings.

[0008] According to some embodiments, a locking post is slidably connected to the inner wall of the retaining ring, and a spring is fixedly connected between the locking post and the inner wall of the retaining ring. A locking hole is opened in the inner wall of the retaining groove, and the locking post can extend into the inner cavity of the locking hole.

[0009] According to some embodiments, multiple sets of the locking pins and locking holes are provided, and they correspond one-to-one. The locking pins and locking holes are evenly distributed around the center of the locking ring, and the top of the locking pin is set as a semi-circle.

[0010] Beneficial effects

[0011] This utility model provides a high-sealing PE corrugated pipe, which has the following beneficial effects:

[0012] (1) The high-sealing PE corrugated pipe uses a snap ring and a snap groove to achieve the snap connection between the right connecting pipe and the left connecting pipe. Then, the rubber blocks on the inner walls of the two sets of fixing rings are snapped between the rings. The fixing bolt is rotated to fix the fixing ring. The fixing ring can strengthen the connection between the left connecting pipe and the right connecting pipe, and the rubber block can seal the connection between the left connecting pipe and the right connecting pipe to prevent leakage at the connection between the left connecting pipe and the right connecting pipe.

[0013] (2) The high-sealing PE corrugated pipe inserts the clasp into the inner cavity of the clasp groove. Under the pressure of the inner wall of the clasp groove, the clasp slides into the inner cavity of the clasp, which in turn compresses the spring and causes the spring to generate a rebound force. After the clasp is fully inserted into the inner cavity of the clasp groove, the clasp is rotated. When the clasp rotates to the clasp hole, under the action of the spring's rebound force, the clasp will slide into the inner cavity of the clasp hole, thereby completing the snap-fit ​​connection of the left connecting pipe and the right connecting pipe. The installation is convenient and quick. Attached Figure Description

[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 1-6 A high-sealing PE corrugated pipe includes a left connecting pipe 1 and a right connecting pipe 101. A first connecting ring 102 is fixedly connected to the side wall of the left connecting pipe 1, and a second connecting ring 103 is fixedly connected to the side wall of the right connecting pipe 101. The pipe also includes:

[0023] The first connecting ring 102 has a slot 2 on its side wall, and the second connecting ring 103 has a retaining ring 201 fixedly connected to its side wall, and the retaining ring 201 can extend into the inner cavity of the slot 2. The top of the first connecting ring 102 and the second connecting ring 103 are both fixedly connected to a circular ring 202. The side walls of the first connecting ring 102 and the second connecting ring 103 are engaged with a fixing ring 203, and two sets of fixing rings 203 are provided. The inner wall of the fixing ring 203 is fixedly connected with a rubber block 204, and the rubber block 204 is engaged between the circular rings 202.

[0024] The side wall of the retaining ring 203 is threaded with a retaining bolt 205, which is used to fix two sets of retaining rings 203.

[0025] It should be noted that: by using the retaining ring 201 on the side wall of the second connecting ring 103 to extend into the inner cavity of the retaining groove 2 opened on the side wall of the first connecting ring 102, the right connecting pipe 101 and the left connecting pipe 1 are connected. Then, the rubber blocks 204 on the inner walls of the two sets of fixing rings 203 are inserted between the rings 202 on the side walls of the first connecting ring 102 and the second connecting ring 103. Then, the fixing bolt 205 is rotated to pass through the two sets of fixing rings 203, thereby fixing the fixing rings 203. The fixing rings 203 can strengthen the connection between the left connecting pipe 1 and the right connecting pipe 101, while the rubber blocks 204 can seal the connection between the left connecting pipe 1 and the right connecting pipe 101, preventing leakage at the connection between the left connecting pipe 1 and the right connecting pipe 101.

[0026] Reference Figures 1-6 A retaining post 3 is slidably connected to the inner wall of the retaining ring 201, and a spring 301 is fixedly connected between the retaining post 3 and the inner wall of the retaining ring 201.

[0027] The inner wall of the slot 2 is provided with a card hole 302, and the card post 3 can extend into the inner cavity of the card hole 302;

[0028] It should be noted that: when the retaining ring 201 is inserted into the inner cavity of the retaining groove 2, the retaining post 3 slides into the inner cavity of the retaining ring 201 under the pressure of the inner wall of the retaining groove 2, thereby compressing the spring 301 and causing the spring 301 to generate a rebound force. After the retaining ring 201 is fully inserted into the inner cavity of the retaining groove 2, the retaining ring 201 is rotated. When the retaining post 3 rotates to the retaining hole 302, under the action of the rebound force of the spring 301, the retaining post 3 will slide into the inner cavity of the retaining hole 302, thereby completing the snap-fit ​​connection of the left connecting pipe 1 and the right connecting pipe 101, and the installation is convenient and quick.

[0029] Reference Figures 1-6 Multiple sets of locking posts 3 and locking holes 302 are provided, and they correspond one to one. The locking posts 3 and locking holes 302 are evenly distributed around the center of the locking ring 201.

[0030] The top of the locking post 3 is set as a semi-circle;

[0031] It should be noted that the design of the locking post 3 and the locking hole 302 facilitates the stable connection of the left connecting pipe 1 and the right connecting pipe 101. The end of the locking post 3 is set to be semi-circular, which facilitates the extension of the locking post 3 into the inner cavity of the locking hole 302.

[0032] Operating method: The retaining ring 201 on the side wall of the second connecting ring 103 extends into the inner cavity of the retaining groove 2 on the side wall of the first connecting ring 102. The retaining post 3 slides into the inner cavity of the retaining ring 201 under the pressure of the inner wall of the retaining groove 2, thereby compressing the spring 301 and causing the spring 301 to generate a rebound force. After the retaining ring 201 is fully inserted into the inner cavity of the retaining groove 2, the retaining ring 201 is rotated. When the retaining post 3 rotates to the retaining hole 302, under the action of the rebound force of the spring 301, the retaining post 3 will slide into the inner cavity of the retaining hole 302, thereby completing the snap-fit ​​connection of the left connecting pipe 1 and the right connecting pipe 101. The installation is convenient and quick.

[0033] Next, insert the rubber blocks 204 on the inner walls of the two sets of fixing rings 203 into the rings 202 on the side walls of the first connecting ring 102 and the second connecting ring 103. Then rotate the fixing bolt 205 through the two sets of fixing rings 203. This fixes the fixing rings 203 and strengthens the connection between the left connecting pipe 1 and the right connecting pipe 101. The rubber blocks 204 can seal the connection between the left connecting pipe 1 and the right connecting pipe 101, preventing leakage at the connection between the left connecting pipe 1 and the right connecting pipe 101.

[0034] 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.
