Abstract
Disclosed is a bus armrest. The left side and the right side of a hanging plate are connected with a transverse rod through two hanging strips symmetrically. The left end and the right end of the hanging plate are provided with two guide pillar holes symmetrically. Limiting round rings are fixedly arranged at the bottom ends of the inner sides of the guide pillar holes correspondingly. Two guide pillars are arranged in the positions, corresponding to the two guide pillar holes in the hanging plate, at the right end and the left end of the upper portion of a pulling rod. The guide pillars are inserted in the two guide pillars holes correspondingly. The upper end of each guide pillar is provided with an annular limiting step. The outer diameter of the limiting steps is larger than the inner hole diameter of the limiting round rings and smaller than the inner hole diameter of the guide pillar holes. Two compression springs are installed on the two guide pillars correspondingly in a sleeving mode. The upper ends of the compression springs are abutted against the limiting steps. The lower ends of the compression springs are abutted against the limiting round rings. The lower portion of the hanging plate is provided with an n-shaped notch. A pull ring shaped like a Chinese character ''kou'' is arranged in the position, corresponding to the notch, of the center of the upper portion of the pull rod. The left end face and the right end face of the pull ring shaped like the Chinese character ''kou'' are in sliding fit with the left side inner wall and the right side inner wall of the notch. The height of the notch is larger than that of the pull ring shaped like the Chinese character ''kou''. Through the bus armrest, personal safety of passengers can be ensured.
Description
Technical field
The present invention relates to bus technical field, specifically a kind of bus handrail.
Background technology
The first-selected vehicles of most of people's go off dailys are mainly bus, in riding process, horizontal handrail in bus is many does not have buffer structure, bus usually because emergency is brought to a halt suddenly or starts suddenly, causes the passenger that stand and topples over because of the effect of inertia in the process of moving.
Summary of the invention
For above-mentioned prior art Problems existing, the present invention provides a kind of bus handrail, and this armrest is simple, can alleviate the inertia effect to human body when bus brakes suddenly or starts suddenly, it is ensured that the Personal Safety of passenger.
To achieve these goals, the present invention provides a kind of bus handrail, including the cross bar in bus, boatswain chair, pull bar and two compression springs, the left and right sides of described boatswain chair is connected with cross bar symmetrically through two suspender belts, the two ends, left and right of boatswain chair are provided with two guide pillar holes with running through short transverse symmetrically, bottom, inboard, described guide pillar hole is fixedly provided with spacing annulus, the two ends, left and right on described pull bar top are provided with two guide pillars in the position corresponding with two guide pillar holes on boatswain chair, two guide pillars are inserted in two guide pillar holes respectively, the upper end of described guide pillar is provided with the limited step of annular, the external diameter of described limited step is more than the internal orifice dimension of spacing annulus and less than the internal orifice dimension in described guide pillar hole, two compression springs are set on two guide pillars, the upper end of described compression spring is against on limited step, its lower end is against on spacing annulus, described boatswain chair bottom is provided with the breach of a shape, described pull bar center upper portion is provided with square shape draw ring in the position of corresponding breach, the left side of described square shape draw ring and right side are slidably matched with the inner left wall of described breach and right side inwall respectively, and the height of described breach is more than the height of described square shape draw ring.
In this technical scheme, it is provided with limited step by the upper end at guide pillar, and the two ends of compression spring are against the lower end of limited step and the upper end of spacing annulus respectively, so when pulling at lower square shape draw ring, compression spring is compressed, and guide pillar can stretch out to the direction away from boatswain chair, and then can start suddenly or during emergency brake at bus, the inertia effect to people can be alleviated by compressing the setting of spring, improve safety, ensured the personal safety of people.
Further, in order to install with easy to maintenance, described limited step is made up of Circular Plate and the screw rod being fixedly installed on Circular Plate bottom, the top axial of described guide pillar offers with the suitable screwed hole of female and described screw rod, and described screw rod is connected with the fixing of guide pillar to realize limited step with screwed hole threaded engagement.
Further, improving buffering effect further to increase, the left and right sides on described pull bar top is connected with the roof of breach respectively through two extension springs.

In figure: 1, cross bar, 2, boatswain chair, 3, pull bar, 4, compression spring, 5, suspender belt, 6, guide pillar hole, 7, spacing annulus, 8, guide pillar, 9, limited step, 10, Circular Plate, 11, screw rod, 12, breach, 13, square shape draw ring, 14, extension spring.
Detailed description of the invention
The invention will be further described below.
As depicted in figs. 1 and 2, a kind of bus handrail, including the cross bar 1 in bus, boatswain chair 2, pull bar 3 and two compression springs 4, the left and right sides of described boatswain chair 2 is connected with cross bar 1 symmetrically through two suspender belts 5, the two ends, left and right of boatswain chair 2 are provided with two guide pillar holes 6 with running through short transverse symmetrically, inboard bottom, described guide pillar hole 6 is fixedly provided with spacing annulus 7, the two ends, left and right on described pull bar 3 top are provided with two guide pillars 8 in the position corresponding with two guide pillar holes 6 on boatswain chair 2, two guide pillars 8 are inserted in two guide pillar holes 6 respectively, the upper end of described guide pillar 8 is provided with the limited step 9 of annular, the external diameter of described limited step 9 is more than the internal orifice dimension of spacing annulus 7 and less than the internal orifice dimension in described guide pillar hole 6, two compression springs 4 are set on two guide pillars 8, the upper end of described compression spring 4 is against on limited step 9, its lower end is against on spacing annulus 7, described boatswain chair 2 bottom is provided with the breach 12 of a shape, described pull bar 3 center upper portion is provided with square shape draw ring 13 in the position of corresponding breach 12, the left side of described square shape draw ring 13 and right side are slidably matched with the inner left wall of described breach 12 and right side inwall respectively, so can ensure that guide pillar 8 will not produce shearing force with guide pillar hole 6 when protruding, so that guide pillar 8 fractures, the height of described breach 12 is more than the height of described square shape draw ring 13. during use, the hand of user is held in the square orifice of square shape draw ring 13, by being provided with limited step 9 in the upper end of guide pillar 8, and the two ends of compression spring 4 are against the lower end of limited step 9 and the upper end of spacing annulus 7 respectively, so when pulling at lower square shape draw ring 13, compression spring 4 is compressed, guide pillar 8 can stretch out to the direction away from boatswain chair 2, and then can start suddenly or during emergency brake at bus, the inertia effect to people can be alleviated by compressing the setting of spring 4, improve safety, ensure the personal safety of people.
