Integral shed cloth for through passage

Abstract

The invention belongs to the technical field of rail transit equipment, and particularly relates to integral shed cloth for a through passage, which is of an integral annular structure formed by connecting four sections of straight cloth and four elbows at intervals, each elbow is of a U-shaped integral structure, and two pieces of side cloth and one piece of middle cloth or connecting cloth of ashed cloth elbow in the prior art are made into a whole body, the whole body and the straight cloth form an integral shed cloth structure, the single-ring shed cloth does not have the problem of sewing lap joints, the sewing process mode of the shed cloth is simplified, the problems of water seepage, water leakage, shed cloth thread opening and shed cloth abrasion caused by sewing threads at shedcloth elbows are solved, and the service life of the shed cloth is prolonged. the integral shed cloth is simple in structrue, the single-ring shed cloth is free of joints, the elbow structure is highin firmness, and the technological mode is simple; during use, multiple rings of shed cloth are connected into a shed cloth assembly through a sewing machine by means of sewing threads to be applied to a through passage, sewing workloads are greatly reduced, and the product using performance is improved.

Description

Technical field: [0001] The invention belongs to the technical field of rail transit equipment, and in particular relates to an integrated shed cloth for a passageway, which can solve the problems of water seepage, water leakage, thread opening at the elbow of the shed cloth of the passageway and the wear of the shed cloth by sewing threads. Background technique: [0002] The through passage is an internal passage for passengers to walk freely from one compartment of rail transit vehicles to another and make passengers feel safe and comfortable. The shed cloth is one of the important components of the through passage. The horizontal fabric can be stretched freely, but the elbow part cannot be stretched to the level of straight fabric due to its own structural problems. The stretching of the shed fabric is mainly achieved by the elasticity of the shed fabric itself. If sewing The stretching amount of the overlapping joints is very small, which will make the sewing overlapping...

AI Technical Summary

Problems solved by technology

[0004] Its sewing process is cumbersome, there are many overlapping sewing parts, and there are water seepage and water leakage. During the repeated stretching process, the probability of the shed cloth opening and sewing thread wearing the shed cloth is increased, thereby shortening the service life of the shed cloth.

Therefore, an integral elbow was developed to solve the problems of water seepage, water leakage and thread opening at the elbow of the through-channel tarpaulin, and the problem of the sewing thread wearing the tarpaulin
