Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, and in particular to an HDPE double-wall corrugated pipe that is easy to connect. Background Technology

[0002] Double-wall corrugated pipe, also known as high-density polyethylene double-wall corrugated pipe or HDPE pipe, is a new type of lightweight pipe with a ring-shaped outer wall and a smooth inner wall. It is a flexible pipe and is mainly used for water supply, drainage, sewage discharge, ventilation, subway ventilation, mine ventilation, and farmland irrigation. The material of polyethylene double-wall corrugated pipe is very strong, durable and stable. Compared with other pipe materials, this double-wall corrugated pipe is less prone to cracking. Multiple corrugated pipes need to be connected for use according to specific application requirements.

[0003] When connecting two double-wall corrugated pipes, flanges are usually used to connect them, and bolts are used to fix the two pipes together. This connection method is relatively simple, requires multiple bolts, and is time-consuming and laborious. Disassembly is also difficult, wasting a lot of time on disassembly and installation, which is very impractical. Therefore, there is an urgent need for an easy-to-connect HDPE double-wall corrugated pipe to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easy-to-connect HDPE double-wall corrugated pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easy-to-connect HDPE double-wall corrugated pipe includes a first corrugated pipe, a second corrugated pipe at one end of the first corrugated pipe, a protective ring on the side of the first and second corrugated pipes that are close to each other, a first connecting ring fixed to one end of the outer wall of the first corrugated pipe, a second connecting ring on the outer wall of one end of the second corrugated pipe, a quick-connect snap-fit ​​mechanism on the side of the first and second connecting rings that are close to each other, and a release mechanism for limiting the contact of the snap-fit ​​mechanism inside the protective ring.

[0007] The snap-fit ​​mechanism includes a fixed housing fixed to the top and bottom of one end of the first connecting ring. A limiting hole is provided on one side of the fixed housing. An insert block is fixed to the top and bottom of one end of the second connecting ring, and the insert block is adapted to the fixed housing. A first mounting groove is provided on one side of the insert block. One end of a first spring is fixed to one side of the inner wall of the first mounting groove. A snap-fit ​​block is fixed to the other end of the first spring, and the snap-fit ​​block is adapted to the limiting hole. A first through groove is provided at the top and bottom of both ends of the protective ring, and the fixed housing is adapted to the first through groove. The end of the snap-fit ​​block near the first corrugated pipe is arc-shaped.

[0008] Preferably, a second through groove is provided on one side of the first through groove, and the second through groove is adapted to the card block. A second mounting groove is provided at the other end of the second through groove, and a release mechanism is provided at the bottom of the interior of the second mounting groove. The protective ring can protect the connection.

[0009] Preferably, the release mechanism includes a U-shaped fixing frame fixed to the bottom of the second mounting groove. The U-shaped fixing frame has first sliding grooves at both ends, and rollers are rolled inside the first sliding grooves. The same first slider is fixed on the side of the two rollers that are close to each other. A right-angled triangular block is fixed on the top of the first slider. A stop post is fixed on the top of the right-angled triangular block near the block, and an anti-slip pad is provided on the other end of the stop post. When the stop post moves, it will squeeze the block and cause the block to disengage from the limiting hole.

[0010] Preferably, the right-angled triangular block has an oblique groove at its angle, and a second slider is slidably mounted inside the oblique groove. The top and bottom of the outer wall of the protective ring are fixed with mounting plates. A pressing rod is provided through the top of the mounting plate, and the bottom of the pressing rod passes through the second mounting groove and is fixedly connected to the top of the second slider. Pressing the pressing rod can drive the right-angled triangular block to move.

[0011] Preferably, one end of the first slider is fixed to one end of the second spring, and the other end of the second spring is fixedly connected to one end of the inner wall of the second mounting groove.

[0012] Preferably, two limiting plates are fixed on the opposite sides of the two mounting plates. Both ends of the two limiting plates are provided with threaded holes, and suitable fixing bolts are provided in the threaded holes. The top of both ends of the pressing rod are provided with holes for the fixing bolts to pass through. The fixing bolts can limit the pressing rod and prevent accidental activation.

[0013] Preferably, the protective ring has a sealing ring inside, and the sealing ring is located at the connection between the first corrugated pipe and the second corrugated pipe.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Due to the use of a snap-fit ​​mechanism, the fixed shell is inserted into the first through slot, and then the insert block is inserted into the fixed shell. The snap block will snap into the limiting hole and limit the connection between the first corrugated pipe and the second corrugated pipe, thereby achieving a quick and more convenient connection between the first corrugated pipe and the second corrugated pipe, saving the connection time between the two corrugated pipes. It is easy to use and simple to operate.

[0016] 2. Due to the adoption of the unrestricting mechanism, the limiting position of the pressing rod is released by the fixing bolt. Then, the pressing rod is pressed down, which presses down on the right-angled triangular block and moves the right-angled triangular block. The right-angled triangular block moves the abutment close to one end of the locking block and squeezes it, causing it to disengage from the limiting hole and retract into the interior of the first mounting groove. This achieves the effect of quickly removing the connection between the first and second corrugated pipes, simplifying the disassembly process, reducing operation steps, and making it more convenient for users.
