Description

Technical Field

[0001] The utility model relates to the technical field of double-wall corrugated pipes, in particular to a double-wall corrugated pipe connector. Background Art

[0002] High-density polyethylene double-wall corrugated pipe is a new type of pipe with an annular outer wall and a smooth inner wall. High-density polyethylene has excellent chemical stability, aging resistance and environmental stress cracking resistance. The double-wall corrugated pipe produced with it as raw material is a flexible pipe.

[0003] Existing double-walled corrugated pipes mostly use a rubber ring socket connection, that is, one end of the double-walled corrugated pipe is made into a socket, and the other end is a spigot. When connecting, the rubber ring is turned over to the first or second groove of the pipe spigot, and then inserted into the socket to ensure that at least 4 grooves are connected to the socket. This connection method is simple and reliable, but the sealing is difficult to ensure. There may be breakpoints in the metal part of the joint. When there is settlement, the breakpoint may form an acute angle, resulting in stress concentration, which may cause the joint to rupture. The metal part of the joint is prone to rust and corrosion, thereby destroying the structural wall; and the double-walled corrugated pipe needs to be processed to make it match two by two, which is inconvenient to use. Therefore, a double-walled corrugated pipe connector with good sealing and convenient use is needed. Utility Model Content

[0005] To solve the above technical problems, the utility model provides a technical solution as follows: a double-walled corrugated pipe connector, comprising a connector body, a first double-walled corrugated pipe and a second double-walled corrugated pipe, the connector body comprising a supporting base plate, a group of connecting plates are symmetrically arranged on the front and rear of the top surface of the supporting base plate, a first movable plate and a second movable plate are symmetrically slidably arranged between the connecting plates, the bottom surface of the supporting base plate is provided with a sliding groove slidably connected to the bottom ends of the first movable plate and the second movable plate, a plurality of first connecting rods are evenly arranged on the side of the first movable plate away from the second movable plate, a first rubber ring is commonly connected to the other end of the first connecting rod, a plurality of second connecting rods are evenly arranged on the side of the second movable plate away from the first movable plate, a second rubber ring is commonly connected to the other end of the second connecting rod, the first double-walled corrugated pipe passes through the first rubber ring and is tightly arranged on the first movable plate, the second double-walled corrugated pipe passes through the second rubber ring and is tightly arranged on the second movable plate, a first connecting sleeve extending to tightly contact the inner wall of the first double-walled corrugated pipe is provided on the first movable plate, and a second connecting sleeve extending to tightly contact the inner wall of the second double-walled corrugated pipe is provided on the second movable plate.

[0006] As an improvement, a bidirectional threaded rod is rotatably provided in the slide groove and is threadedly connected to the bottom ends of the first movable plate and the second movable plate, and a twisting handle is rotatably provided on the outer wall of the supporting bottom plate for driving the bidirectional threaded rod, thereby facilitating the close connection operation of a group of double-wall corrugated pipe bodies.

[0007] As an improvement, the inner wall of the second connecting sleeve is provided with an extension connecting pipe extending into the first connecting sleeve.

[0008] When the pipe is connected to the double-wall corrugated pipe body, the movable plates are moved closer to each other and the connecting pipe is extended into the first connecting sleeve and closely adheres to the inner wall thereof, thereby improving the sealing effect.

[0009] As an improvement, a sealing groove is provided on the side of the first movable plate close to the second movable plate, and a sealing ring matching the sealing groove is provided on the side of the second movable plate close to the first movable plate, so that the connection between the first movable plate and the second movable plate is sealed.

[0010] As an improvement, the outer walls of the first connecting sleeve and the second connecting sleeve are both made of smooth material and coated with lubricant to facilitate the installation of the first double-wall corrugated pipe and the second double-wall corrugated pipe.

[0011] Compared with the prior art, the utility model has the following advantages: a group of identical double-walled corrugated pipe bodies are placed on both sides of the connector body, and the rubber rings on both sides of the connector body are turned over to the first or second groove of the double-walled corrugated pipe body socket, and the connecting sleeve on the connector body enters the double-walled corrugated pipe, and then a group of movable plates are moved close to each other until they are close to each other, so that the connection operation of the double-walled corrugated pipe body can be quickly completed, which is convenient to use, and the multiple connection structures greatly improve the sealing performance.
