Structure-stable telescopic bus handle

Abstract

The invention discloses a structure-stable telescopic bus handle. The bus handle comprises a transverse fixing rod, a box body, a rotating wheel, a torsion spring, a fixing mechanism and a handle ring. Compared with the prior art, the structure-stable telescopic bus handle is characterized in that a starting mechanism and a fixing mechanism are adopted for well guaranteeing the use requirements ofpeople with normal height under an original state, a hard hand ring sleeve top and the fixing mechanism are made of hard materials, and it is guaranteed that the whole device does not shift when grasping the handle; after the starting mechanism is opened, the handle can be rotated to a vertical passage, the hard hand ring sleeve top is separated from the fixing mechanism by pulling downwards, pulling operation stops downwards after a connecting position between a pull rope and a rotating wheel is completely tightened, at the moment, the handle is lowered by 5-10 centimeters in the height andis used for allowing short people for using; after the use is finished, the handle is loosened, the handle is restored to the original position under the action of the torsion spring and a magnet, thehandle is rotated to enable the hard hand ring sleeve top to be inserted into the fixing mechanism, and the starting mechanism is closed. The structure-stable telescopic bus handle has the advantagesof being simple in using, stable in structure, and suitable for people with different heights to use.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a retractable bus handle with a stable structure. Background technique [0002] In the 21st century, with the accelerated development of cities and the improvement of modernization, the operation of buses in big cities plays an indispensable role. It not only bears the mission of daily traffic for citizens, but also reflects the development level of modern cities in my country from the side. At the same time, with the increase of private car ownership, my country's urban traffic development is facing increasingly severe pressures such as traffic congestion, environmental pollution, traffic safety, and energy consumption. Vigorously promoting public transportation is one of the ways to alleviate these problems. However, the height of the passengers in the bus varies. For children, the elderly and some passengers with a lower height, they are 5-10 cm lower than the average height...

AI Technical Summary

Problems solved by technology

However, the height of the passengers in the bus varies. For children, the elderly, and some passengers with low height, they are 5-10 cm below the average height, and they cannot pull the handrails when taking the bus, which will easily cause the passengers to lose their center of gravity. Stable, easy to fall and cause unnecessary injury

For passengers whose height can barely reach the armrest, lifting the arm up for a long time will cause static load on the shoulder, arm, and hand muscles, resulting in fatigue. When the driver steps on the brakes, it is easy to cause arm strain or unstable standing Happening
