Baffle type locking mechanism

Abstract

The invention belongs to the technical field of rail transit equipment, and relates to a baffle type locking mechanism which is fixed in the middle of the lower surface of a cab apron body and clamps a sliding pedal and a positioning pedal together with the cab apron body through a movable baffle, a fixed baffle and the cab apron body, vertical locking of a cab apron assembly is achieved, and the attractiveness of the cab apron assembly cannot be affected. The movable baffle makes sliding contact with the friction piece in the horizontal direction, other mechanisms do not need to be additionally arranged outside, the locking position of the movable baffle is always in the locking state through the automatic reset function of the movable baffle, secondary observation and confirmation are not needed, the false locking phenomenon of the cab apron assembly is avoided, and the locking mechanism cannot be automatically opened; the locking performance of the cab apron assembly is safe and reliable; the buffer head can guarantee the coincidence degree of the movable baffle and the positioning pedal and can also guarantee that the elastic supporting plate is always in a tensioning state, and the situation that when a vehicle moves, the movable baffle is driven to vibrate, and noise is generated is avoided. The structure is reasonable, operation is easy, installation is convenient, the principle is scientific, and the safety of the through channel is guaranteed.

Description

Technical field: [0001] The invention belongs to the technical field of rail transit equipment, and in particular relates to a baffle-type locking mechanism, which can easily and quickly realize the installation and disassembly of a transition plate without secondary observation and confirmation, and ensures safe and reliable locking performance of the transition plate. Background technique: [0002] Passageway is an important common part of rail vehicles, used to connect two adjacent carriages, so that passengers can pass or stay safely, and feel safe and comfortable. During the operation of the rail vehicle, the passage needs to meet the requirements of the rail vehicle to pass the curve. Among the three panels of the floor structure of the passage, the one in the middle is called the transition board, and the two sides are pedals. The transition board and the pedal are overlapped together. , through the connecting rod mechanism of the crossing board, the crossing board is...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patented product and the crossing plate locking mechanism in the prior art have cumbersome locking methods, and need to rely on other mechanisms to maintain the locked state, and it is necessary to confirm whether the crossing plate is locked through secondary observation, and the train is running. Vibration leads to a series of problems such as accidental unlocking, causing safety hazards

Therefore, it is of great social and economic value to develop a locking mechanism with a baffle-type structure to realize the rapid installation and disassembly of the crossing board and completely avoid the safety hazard caused by the improper locking of the crossing board.
