Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: a polyethylene double-wall corrugated pipe comprises a corrugated pipe 1, wherein a nut 2 is fixed on the corrugated pipe 1, bolts 3 are connected with the nut 2 through threads, the bolts 3 penetrate through a mounting seat 4 and are in threaded connection with the mounting seat 4, the mounting seat 4 is provided with two groups, each group of mounting seats 4 is provided with two groups, one group of mounting seats 4 is fixed on the surface of a connecting ring A5, circular clamping grooves are arranged on a connecting ring A5 in a circular array shape, the other group of mounting seats 4 is fixed on a connecting ring B6, connecting equipment 7 convenient to connect is arranged on the connecting ring B6, and through the mutual matching of the nut 2, the bolts 3 and the mounting seats 4, the connection rings B6 and A5 can be conveniently detached while the connection rings B6 and A5 can be conveniently and stably fixed on the corrugated pipe 1, therefore, when the corrugated pipe 1 is connected with other pipelines, the connection is more convenient, and different connection modes can be adapted.

In this embodiment, the connection device 7 includes a slip ring 71, a spring 72, and a sealing rubber ring 73, the slip ring 71 is slidably mounted on a connection ring B6, the spring 72 is sleeved on a connection ring B6, the sealing rubber ring 73 is fixed on the connection ring B6, the connection device 7 further includes a bracket 74 and a stopper rod 75, one end of the bracket 74 is hinged to the slip ring 71, the other end of the bracket 74 is hinged to the stopper rod 75, the stopper rod 75 penetrates through the connection ring B6 and is slidably connected in the connection ring B6 in a circular array, the stopper rod 75 is "conical", a cross section of the sealing rubber ring 73 is "Z", a diameter of the connection ring a5 is greater than a diameter of the connection ring B6, when the bellows 1 is connected, the connection of the bellows 1 can be achieved by directly inserting the connection ring B6 into the connection ring a5, and at the connection ring B6 is inserted into the connection ring a5, the stopper rod 75 is conical, the inclined plane of gag lever post 75 can receive the extrusion of go-between A5, contract in go-between B6, after the round slot that gag lever post 75 and go-between A5 seted up is parallel, through spring 72, sliding ring 71 and support 74 mutually support, bounce the gag lever post 75 into the round slot, go-between A5 and go-between B6's connection, thereby realize bellows 1's connection, when go-between B6 inserts in go-between A5, go-between A5 can extrude sealing rubber circle 73, sealing rubber circle 73 can hug closely the inner wall of go-between A5, guarantee that liquid can not flow out through go-between A5 and go-between B6 junction gap, thereby when making things convenient for bellows 1 to connect, guarantee bellows 1's normal use.

During operation (or during use), when connecting bellows 1, through directly inserting go-between B6 in go-between A5, go-between B6 is when inserting go-between A5, because the shape of gag lever post 75 is the toper, the inclined plane of gag lever post 75 can receive the extrusion of go-between A5, contract in go-between B6, after gag lever post 75 is parallel with the circular draw-in groove that go-between A5 was seted up, through spring 72, the mutual cooperation of sliding ring 71 and support 74, bounce the gag lever post 75 in the circular draw-in groove, go-between A5 and go-between B6's connection, thereby realize the connection of bellows 1.
