Worm wheel-worm hoop and rubber pipe assembly and installation method thereof

Abstract

The invention relates to the field of automobile pipeline connection, in particular to a worm wheel-worm hoop and rubber pipe assembly and an installation method thereof. The worm wheel-worm hoop and rubber pipe assembly comprises a rubber pipe and a worm wheel-worm hoop. The worm wheel-worm hoop is installed at an end opening of the rubber pipe. An arch-shaped clamping jaw is arranged on a steel strip of the outer ring of the worm wheel-worm hoop. The upper end of the arch-shaped clamping jaw is a sharp point jaw head which is bent toward the inner wall of the rubber pipe. The sharp point jaw head is used for being connected with the edge of the end opening of the rubber pipe in a clamped mode. The sharp point jaw head of the arch-shaped clamping jaw of the worm wheel-worm hoop and rubber pipe assembly is completely concealed into the inner wall of the rubber pipe, so that fixed connection of the worm wheel-worm hoop and the rubber pipe is ensured, and accordingly the worm wheel-worm hoop is prevented from sliding and falling off from the worm wheel-worm hoop and rubber pipe assembly.

Description

technical field [0001] The invention relates to the field of road connection of automobile pipelines, in particular to a worm gear clamp rubber hose assembly and an installation method thereof. Background technique [0002] At present, the connection of the flexible rubber hose fluid pipeline in the automotive field usually adopts a clamp connection. Due to the large clamping force and adjustable clamping state of the worm gear clamp, the clamping force is not significantly changed by the change of the pipeline material and size, so the worm gear clamp is often used for the connection of large-diameter pipelines. [0003] In order to make the assembly more convenient for the workers in the automobile factory, the worm gear and worm clamps assembled at the end of the pipe body before leaving the factory are usually not locked. Ensure that the liquid or gas in the hose does not leak. Therefore, the clamp rubber hose assembly faces a problem of how to fix the clamp and the ru...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the worm gear clamp is generally assembled to the rubber hose with an arc-shaped metal clip with a radian of 30°-45°. This connection method is easy to slide or fall off before the clamp locks the rubber hose, which will seriously cause the automobile assembly line to stop. Wire

In addition, the arc-shaped metal clips cannot fit rubber hoses of various outer diameters well due to their large radians. As a result, after being assembled to the hose ports, the roundness of the hose will be deformed, which will affect the performance of the product.
