Embodiment Construction

[0017] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0018] Such as figure 1 As shown, the present invention includes the following technical features: locking teeth 1, nylon cylinder body 2, flange end face 3, and retaining ring 4.

[0019] A nylon buckle-type sheath for improving the safety of electrical wiring of railway passenger cars of the present invention includes a nylon cylinder body, one end of the nylon cylinder body is set as a flange end face, and the other end is a movable end, which is set as an opening Two groups of grooves are opened along the axial direction of the nylon cylinder body on the circumference of the movable end, and a locking tooth is formed between each group of grooves. The loc...

Abstract

The invention relates to a nylon buckle type sheath for enhancing electric wiring safety of a passenger train and an application method. The nylon buckle type sheath comprises a nylon column body. One end of the nylon column body is arranged as a flange end surface while the other end is a movable end which is arranged in an opening shape, two sets of slots are formed along the axial direction of the nylon column body on the circumference of the movable end, a latch is formed between each group of slots, and a bump is arranged on the portion on the outer side of the circumference of the nylon column body; the nylon buckle sheath also comprises a retainer ring which sleeves the nylon column body, is located below the bump of the latch, and clings to the bottom end of the bump to clamp the movable end of the nylon column body. After the nylon buckle type sheath is mounted and used, the electric wiring safety and reliability of the passenger train can be effectively enhanced. In the aspect of a structural design, fast and convenient actual demands on construction site operation are considered, so that the workload is reduced and the production efficiency is improved.

Description

technical field [0001] The invention relates to a nylon buckle-type sheath for improving the safety of electric wiring of railway passenger cars and a use method thereof, belonging to the technical field of electric wiring of railway passenger cars. Background technique [0002] At present, in the railway passenger car industry, the quality and safety of the source of product design is comprehensively rectified and improved, especially when it comes to the safety of electrical wiring. The safety and reliability of wiring protection is one of the key factors. The secondary protection methods at the lintel holes of the electrical wiring of existing railway passenger cars are roughly divided into two types, one is not protected, and the other is treated by wrapping rubber. The existing scheme has hidden dangers to the safety and reliability of wiring, and is not conducive to on-site operation, and the production efficiency is low. Contents of the invention [0003] The inven...
