An anti-sudden braking bus hoisting ring

Abstract

The invention discloses an anti-emergency-brake bus lifting ring. The lifting ring comprises a shell, wherein the shell is of a circular barrel-shaped structure; a plurality of cylinders are symmetrically arranged on the inner wall of the shell, a piston is hermetically and slidably connected to the inner wall of each cylinder, and each piston is fixedly connected with a push rod; the side, away from the corresponding piston, of each push rod is fixedly connected with an arc-shaped plate. The lifting ring has the advantages that when a bus takes a sudden turn and brakes, a standing passenger can tightly hold and pull a holding ring with force subconsciously, a round plate is driven to move downwards to make a straight rod extrude a baffle, and a U-shaped plate extends into a hard tube, sothat the effective cross-sectional area of liquid flowing in the straight rod and the hard tube is reduced, and the amount of a fluid which can flow through in unit time in the hard tube is greatly reduced, that is, the fluid in each cylinder cannot be rapidly circulated. Therefore, the holding ring generates large supporting force on the hands of the passenger, and the situation that the passenger falls down is avoided.

Description

technical field [0001] The invention relates to the technical field of bus accessories, in particular to an anti-emergency brake bus suspension ring. Background technique [0002] Buses are an important part of urban public transportation, an important aspect of urban construction, and play the most basic role in promoting urban development. In order to ensure the safety of standing passengers as much as possible, cross-bar handrails and suspension rings installed on the cross-bar handrails are generally provided on the bus. Passengers generally ensure their own balance by holding the suspension rings tightly. [0003] In actual use, when the bus makes a sharp turn or brakes suddenly, due to the non-rigid connection between the suspension ring and the cross-bar handrail, there is a considerable space for movement, and the probability of shaking is relatively high, which is extremely unstable. Hold the suspension ring tightly Passengers tend to shake in the compartment with ...

[0003] In actual use, when the bus makes a sharp turn or brakes suddenly, due to the non-rigid connection between the suspension ring and the cross-bar handrail, there is a considerable space for movement, and the probability of shaking is relatively high, which is extremely unstable. Hold the suspension ring tightly Passengers tend to shake in the compartment with the suspension rings, and are prone to fall
