[0002] At present, during the manufacturing process of ordinary wire hoses, the wires are usually wrapped in the hoses and fixed in the hoses with glue. Since the glue is corrosive as a whole, and the hose surface is not adequately protected during the entire use of the hose to prevent it from being corroded, the hose will be damaged faster when stretched and bent, resulting in the hose failing to meet the service life requirements of vacuum cleaners and cleaning machines. Summary of the invention
[0003] The purpose of the embodiments of the present application is to provide a pull-down tube that can solve the technical problem of the service life of the pull-down tube.
[0004] The embodiment of the present application provides a pull-pull tube, comprising a tube body, wherein the tube body comprises a placement groove and a buffer groove, wherein the placement groove is spirally arranged inside the tube body, and the buffer groove is spirally arranged outside the tube body;
[0005] An anti-damage pad is arranged in the placement groove, the anti-damage pad is integrally formed with the bottom of the placement groove, and the wire is fixedly arranged on the anti-damage pad.
[0006] Furthermore, a protective sheath layer is fixedly arranged on the anti-damage pad, and the wire is fixedly arranged between the anti-damage pad and the protective sheath layer.
[0007] Furthermore, a telescopic sheet is fixedly arranged outside the buffer groove.
[0008] Furthermore, the expansion piece is arranged in a V shape, and a buffer space is formed between the expansion piece and the buffer groove.
[0009] Furthermore, the tube body is made of polypropylene pp8003.
[0010] Beneficial effects of the utility model:
[0011] The pull-pull tube provided by the utility model comprises a tube body, on which a placement groove and a buffer groove are arranged. By arranging an anti-damage pad in the placement groove, the corrosion of the tube body by the glue fixing the wire in the tube body can be effectively protected. At the same time, the arrangement of the anti-damage pad can also enhance the wear resistance of the tube body during bending and stretching, thereby extending the service life of the tube body.
[0012] By fixing a protective cover layer on the anti-damage pad, the surface of the wire and the anti-damage pad can be effectively protected from being worn when the pipe body is in use, thereby ensuring the service life.
[0013] The provision of the expansion piece can effectively reduce the impact of the tube body's contraction when it is compressed, and enhance the tube body's stretching and restoring ability. BRIEF DESCRIPTION OF THE DRAWINGS
