Hydraulic control type bus lifting ring

Abstract

The invention discloses a hydraulic control type bus lifting ring, which comprises a handrail, wherein the side wall of the handrail is fixedly sleeved with a fixed block, a pull ring is arranged at the lower end of the fixed block, two control grooves are formed in the lower wall of the fixed block, the inner walls of the two control grooves are fixedly connected with steel wire hoses, the lowerwalls of the two steel wire hoses are jointly and fixedly connected with a connecting box, the lower walls of the two steel wire hoses communicate with the connecting box through communicating openings, the lower wall of the connecting box is fixedly connected with the pull ring, the two steel wire hoses are filled with a filling liquid, the inner wall of the connecting box is connected with a control panel in a sealed and sliding mode, the side wall of the control panel is fixedly connected with two control plugs matched with the communicating openings, and the side wall of the inner ring, close to the lower end, of the pull ring is fixedly connected with an air bag. According to the invention, passengers can be effectively helped to well guarantee the balance of themselves, and the situation that the pull ring slips off the hand due to sweating of heat generated by friction when people hold the pull ring for a long time is prevented.

Description

technical field [0001] The invention relates to the technical field of public equipment, in particular to a liquid-controlled bus suspension ring. Background technique [0002] Due to the large number of people on the bus, the seats on the bus are often not enough, and the passengers usually stand on the bus. In order to make the passengers stand more stably, some suspension rings are arranged on the bus. People can hold the lifting rings to ensure their own balance. These rings can usually be shaken for the convenience of passengers to adjust their positions. At the same time, the passenger and the suspension ring will move forward due to inertia, which will easily cause the passenger to fall down and cause danger. Therefore, a kind of bus suspension ring needs to be designed to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a hydraulically controlled bus suspens...

Problems solved by technology

[0002] Due to the large number of people taking the bus, the seats on the bus are often not enough to use, and the passengers usually stand on the bus. In order to make the passengers stand more stably, some suspension rings are arranged on the bus. People can hold the lifting rings to ensure their own balance. These rings can usually shake for the convenience of passengers to adjust their positions. However, during the driving process of the car, there will usually be some emergency braking. At this time, the passengers and the rings will move forward due to inertia, which will easily cause the passengers to fall and cause danger. Therefore, it is necessary to design a bus ring to solve the above problems
