Problems solved by technology

At present, the water pipes used for cleaning are not stretchable, and PVC plastic pipes are generally used. The disadvantages are: first, the water pipes are piled on the ground, which will easily lead to chaos on the site, easy to knot, and easy to be trampled and damaged. The service life of the water pipe is short; the second is that due to the high hardness, it is not easy to fold and store, and it takes up a lot of space during storage; the third is that the connection between the water pipe and the water source and the nozzle is inconvenient

Embodiment Construction

[0024] The invention will be further described below in conjunction with the accompanying drawings with specific embodiments, see figure 1 —3:

[0025] A kind of production technology of equal-proportion telescopic expansion tube, concrete steps are as follows:

[0026] 1) Set the elastic fabric tube 1 outside the inner tube 2. The inner tube can be stretched axially and expanded radially. The elastic fabric tube is a two-way elastic fabric in warp and weft. The elastic fabric tube is woven with spandex-coated yarn and polyester The tubular fabric formed, spandex covered yarn adopts 75% spandex high elastic yarn 42D and 25% polyester network yarn 75D, spandex high elastic yarn is polyurethane fiber, and polyurethane fiber is made of PTMEG (polytetramethylene Ether diol) and MDI (diphenylmethane diisocyanate) polymerized;

[0027] 2) Set the metal sleeve 3 or the claw 4 and the locking sleeve 5 on both ends of the elastic cloth pipe 1;

[0028] 3) inserting the two ends of t...

Abstract

The invention belongs to the technical field of water pipes, and particularly relates to a production process of an equal-proportion stretching and retracting expansion tube. The process specifically includes the following steps that first, an inner tube is sleeved with an elastic cloth tube; second, the two ends of the elastic cloth tube are respectively sleeved with a metal sleeve or a clamping claw and a locking sleeve; third, the two ends of the inner tube are inserted in inserting connection parts of a joint in a connected mode respectively; fourth, the metal sleeves in the second step are moved to the end, corresponding to the position outside the inserting connection parts, of the elastic cloth tube, and a metal tube is pressed so that the two ends of the inner tube and the two ends of the elastic cloth tube can be fixed to the corresponding inserting connection parts respectively; or the clamping claws are moved to the end, corresponding to the position outside the inserting connection parts, of the elastic cloth tube, and the two ends of the inner tube and the two ends of the elastic cloth tube can be fixed to the joint; fifth, the locking sleeves are connected to the joint in a screwed mode so that installation can be achieved. The inner tube and the elastic cloth tube of the stretching and retracting expansion tube manufactured with the method stretch and retract in equal proportion, it is guaranteed that an elastic cloth sleeve is evenly retracted outside the inner tube, and it is guaranteed that equal-proportion retracting and stretching can be achieved in next time use.

Description

technical field [0001] The invention belongs to the technical field of water pipes, in particular to a production process of equal-proportion telescopic expansion pipes. Background technique [0002] In some necessary occasions, such as: car washing, in the cleaning process, because the car has a certain length, a longer length of water pipe should be prepared to ensure the smooth progress of the cleaning work. At present, the water pipes used for cleaning are not stretchable, and PVC plastic pipes are generally used. The disadvantages are: first, the water pipes are piled on the ground, which will easily lead to chaos on the site, easy to knot, and easy to be trampled and damaged. The service life of the water pipe is short; the second is that due to the high hardness, it is not easy to fold and store, and it takes up a lot of space during storage; the third is that the connection between the water pipe and the water source and the nozzle is inconvenient. Contents of the ...
