Description

A kind of locomotive shock-absorbing seat

The utility model relates to a kind of locomotive shock-absorbing seat, belongs to locomotive accessory equipment class.

The all types of electric locomotives of our factory production for many years all adopt TXJT-120-000 type seat, though this seat overall performance is reliable, durable in use, owing to the reason on the structure design, have that the operation of each position is dumb, manufacture difficulty is big, and defective such as outward appearance and comfort level be also poor.These defectives mainly show following several respects: first jacking system adopts the lifting of handle type gear, and not only rotating operation is dumb, and the seat that whenever circles can only lifting 10mm, and its Gear Processing difficulty is also big; It two is that the adjusting that moves forward and backward of seat cushion is realized by the outer and inner tube slide displacement that is nested with, not only must be with special-purpose bed accessory processing, and two-tube necessary parallel, otherwise an alerting ability will not be had in displacement; Though it three is that backrest can tilt forward and back 20 degree, because five gears only are stuck in the crescent plate with the handle pin, seems inconvenient during operation: it four is that to control the sleeve mechanism difficulty of processing of seat left-right rotation big; It five is that seat cushion and backrest only depend on sponge foaming part to realize damping, so also not good every, damping performance.

Therefore, raising along with the railway locomotive running velocity, how to improve and improve driver and conductor's working environment, improve the comfort level and the antifatigue degree of working environment, providing outer U.S. interior novel locomotive shock-absorbing seats excellent, multiple functional, easy to operate, safety and comfort to them is urgent and a be of practical significance thing.This also is the purpose of the present utility model place.
