Embodiment 1

[0028] A double-wall bellows tee connection piece, comprising a first connecting pipe 100 , a second connecting pipe 200 and a third connecting pipe 300 . The first connecting pipe 100 , the second connecting pipe 200 and the third connecting pipe 300 all meet at the base 400 .

[0029] The outer diameters of the first connecting pipe 100 , the second connecting pipe 200 and the third connecting pipe 300 are all adapted to the inner diameter of the double-wall corrugated pipe. The first connecting pipe 100 , the second connecting pipe 200 and the third connecting pipe 300 are sleeved inside the double-wall corrugated pipe and adhere to the inner wall of the double-wall corrugated pipe. The inner diameter of the first connecting pipe 100 , the second connecting pipe 200 and the third connecting pipe 300 gradually decrease from the outside to the inside, and the wall thickness increases to reduce water flow resistance.

[0030] The outer walls of the first connecting pipe 100 ,...

Embodiment 2

[0043] This embodiment is suitable for placing cables.

[0044] The base 400 defines a through hole 401 . The third connecting pipe 300 is connected to the through hole 401 of the base 400 .

[0045] A guiding piece 600 is sheathed inside the base 400 . The guide 600 includes a guide sleeve 601 , a guide ring 602 and a guide strip 603 . The guide sleeve 601 is a hollow cylinder, one end of the guide sleeve 601 is fixedly connected to the guide ring 602 , and the outer wall of the other end is provided with guide strips 603 at equal intervals in the axial direction. The inner wall of the guide bar 603 is fixed to the guide sleeve 601 , and the outer wall is attached to the inner wall of the base 400 . Both ends of the guide bar 603 are chamfered. The through hole 401 is located between the guide bar 603 and the guide ring 602 .

[0046] The base 400, the guide sleeve 601 and two adjacent guide strips 603 form a guide cavity.

[0047] When the cable is laid from the third ...

Abstract

The invention provides a double-wall corrugated pipe tee-joint connecting piece and belongs to the technical field of corrugated pipe connecting pieces. The double-wall corrugated pipe tee-joint connecting piece comprises a first connecting pipe, a second connecting pipe and a third connecting pipe. The first connecting pipe, the second connecting pipe and the third connecting pipe are joined at a base. The outer diameters of the first connecting pipe, the second connecting pipe and the third connecting pipe are matched with the inner diameter of a double-wall corrugated pipe. The outer walls of the first connecting pipe, the second connecting pipe and the third connecting pipe are provided with clamping buckles at equal space distance around the axes. The clamping buckles comprise base rods, clamping rods, holding rods and buckling rods. The base rods extend out in the radial direction of the outer walls of the connecting pipes. The clamping rods are arranged in the axial direction. The inner ends of the clamping rods are fixed at the tops of the base rods vertically. The buckling rods extend out in the radial direction of the inner sides of the clamping rods. The tee-joint connecting piece is suitable for being connected with the double-wall corrugated pipe, the double-wall corrugated pipe is inserted to a corresponding connecting pipe of the connecting piece, the two parts are tightly combined, and the sealing performance of the two parts is guaranteed. A detachable connecting mode is used, mounting and detaching are easy, and worker bare-handed operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of corrugated pipe connectors, in particular to a double-wall corrugated pipe tee connector. Background technique [0002] Double-wall corrugated pipe is a new type of pipe with a ring-shaped outer wall and a smooth inner wall. It has excellent chemical stability, aging resistance and environmental stress cracking resistance. [0003] Traditional double-wall corrugated pipes are usually connected by hot melting or applying waterproof glue at the joints, and then welding at the joints. The double-wall corrugated pipes of different materials cannot be welded uniformly after hot-melting, and welding with one of the welding rods of one material has certain safety hazards in its welding strength, and the quality of the product cannot be guaranteed. Moreover, in the prior art, there is a lack of connectors suitable for multiple equal-diameter double-wall corrugated pipes. Contents of the invention [0004] The...
