Abstract

The invention discloses a bus handle. The bus handle comprises a transverse rod, a hanging board, a square pull ring and two compression springs, wherein the left side and the right side of the hanging board are symmetrically connected with the transverse rod through two hanging belts, two guide pillar holes are symmetrically formed in the left end and the right end of the hanging board in a penetrating manner in a height direction, and spacing rings are fixedly arranged at bottom ends on the inner sides of the guide pillar holes; two guide pillars are arranged at positions, corresponding to the two guide pillar holes in the hanging board, at the left end and the right end of the upper part of the square pull ring, and are respectively inserted and mounted in the two guide pillar holes; annular spacing steps are arranged at the upper ends of the guide pillars, and the outer diameters of the spacing steps are greater than the inner hole diameters of the spacing rings and are smaller than the inner hole diameters of the guide pillar holes; the two compression springs are respectively mounted on the two guide pillars in a sleeving manner, the upper ends of the compression springs are abutted to the spacing steps, and the lower ends of the compression springs are abutted to the spacing rings. The handle is simple in structure, and can alleviate effects of inertia to human bodies when a bus brakes suddenly or starts suddenly, so that the personal safety of passengers can be guaranteed.

Description

A kind of bus handle

Technical field

The present invention relates to bus technical field, specifically a kind of bus handle.

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 handle, and this pull handle arrangement 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.

nullTo achieve these goals，The present invention provides a kind of bus handle，Including the cross bar in bus、Boatswain chair、Square shape draw ring 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 square shape draw ring 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.

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, in order to prevent square shape draw ring from use accidentally injuring people, the corner of described square shape draw ring is circular arc transition.

Fig. 2 is the structural representation of the guide pillar in the present invention and limited step.

In figure: 1, cross bar, 2, boatswain chair, 3, square shape draw ring, 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.

Detailed description of the invention

The invention will be further described below.

nullAs depicted in figs. 1 and 2，A kind of bus handle，Including the cross bar 1 in bus、Boatswain chair 2、Square shape draw ring 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 square shape draw ring 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.During use, the hand of user is held in the square orifice of square shape draw ring 3, 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 3, 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.

In order to install with easy to maintenance, described limited step 9 is made up of Circular Plate 10 and the screw rod 11 being fixedly installed on Circular Plate 10 bottom, the top axial of described guide pillar 8 offers with the suitable screwed hole of female and described screw rod 11, and described screw rod 11 is connected with the fixing of guide pillar 8 to realize limited step 9 with screwed hole threaded engagement.

In order to prevent square shape draw ring 3 from use accidentally injuring people, the corner of described square shape draw ring 3 is circular arc transition.
