Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 and figure 2 As shown, the telescopic armrest of the present invention includes a fixed cross bar 1, and also includes a handle 3 and a fixed rope 2. The fixed rope 2 can be fixed on the cross bar 1 through a fixing member, and the end of the fixed rope 2 is far away from the cross bar 1. It is connected with the handle 3, and the fixed rope 2 is wound inside the fixed part through the elastic piece; by pulling the handle 3, the fixed rope 2 can be stretched out or retracted; it also includes a locking part, which can control the fixed rope 2 extended or retracted. The device preferably wraps the fixing rope 2 partly in the fixing member, so that the above-mentioned structure is similar to that of a steel tape measure, and the length of the fixing rope 2 can be changed by stretching. In actual use, the length of the fixed rope 2 can be chang...

Abstract

The invention discloses a telescopic handrail. The telescopic handrail comprises a fixed cross bar (1), a handle (3) and a fixing rope (2), wherein the fixed rope (2) can be fixed on the cross bar (1)through a fixing piece, one end, far away from the cross bar (1), of the fixed rope (2), is connected with the handle (3), the fixed rope (2) is wound in the fixing piece through an elastic piece, and stretching or retracting of the fixed rope (2) can be realized by pulling the handle (3). The telescopic handrail further comprises a locking piece, wherein the locking piece can control the stretching or the retracting of the fixed rope (2). The telescopic handrail can wind a part of the fixed rope in the fixing piece, can change the length of the fixed rope (2) by pulling the handle, meets holding of people different in height, and is convenient to use in practice. Meanwhile, the length of the fixed rope (2) can be controlled through the locking piece, and therefore the whole structure isstable.

Description

technical field [0001] The invention discloses a telescopic handrail, which belongs to the field of bus auxiliary tools. Background technique [0002] Buses are widely used in people's daily life as a common means of public transportation. Especially for some small and medium-sized cities, buses undertake a large amount of transportation work in the city. And the internal space of existing public transport is big, and on its inner wall, horizontal and vertical staggering is provided with some support rods, and vertically is provided with some handles on the support rods of horizontal arrangement. Handle is connected and fixed with cross bar by fixed rope, because handle is mainly used in supporting people and prevents from toppling over, so existing fixed rope length is fixed, and can not be adjusted. This structure often makes it inconvenient for some people with short stature to hold it, and even cannot grasp the handle at all, resulting in inconvenient actual use. Con...
