Description
Technical field
The utility model relates to a kind of release and latching device, specifically a kind of release and latching device that is used to satisfy train seat spinfunction needs.
Background technology
The train of high-speed cruising, the seat that need adapt with it, with safety and the comfort seat requirement of satisfying the passenger, the fixed type arm-chair formula seat that existing train passenger seat major part is a flexible hard seat, take this kind seat on the train of speed per hour more than 200 kilometers, it can not satisfy traveling comfort is conspicuous.For satisfying the traveling comfort that seat uses, functions such as some seats can be realized the seat rotation, backrest angle is adjustable, seat moves forward and backward also appear now, but because backrest angle changes and the moving of seat in the use, make seat when rotated because in time not the resetting of backrest and seat, and influence the spinfunction of seat, thereby be passenger's the use profit of making troubles.
Therefore, design a kind of release and the latching device that before the seat rotation, can realize backrest angle and seat return, make things convenient for the rotation of realization seat, become the technical barrier that those skilled in the art press for solution.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of release and the latching device that are used for the train seat rotation simple in structure, esy to use, safe and reliable, with the spinfunction that satisfies train seat, the comfort level that improves existing train seat.
The technical scheme of the utility model technical solution problem is as follows:
A kind of release and latching device that is used for the train seat rotation comprises pedal, pedal support, Bowden cable support, Bowden cable, release guide plate and retracing spring; Pedal and pedal support are rotationally connected; The pedal upper end is fixed with roller; Pedal support is captiveed joint with the Bowden cable support; Bowden cable installs and fixes by the Bowden cable support, and the one end is captiveed joint with the release pedal; Captive joint with the Bowden cable support with pedal respectively in the retracing spring two ends, described Bowden cable support and release guide plate are fixedly installed on the seat underframe, described release guide plate is provided with the locking spigot surface and the release spigot surface of lockable roller, during locking state, roller is positioned at locking spigot surface place; During released state, roller is positioned at release spigot surface place.
Described release guide plate is to comprise a plane and common constitute irregular tabular of arcwall face; Described locking spigot surface is the plane, release spigot surface arcwall face.
By above disclosed technical scheme as can be known, the purpose of this utility model is achieved in that at first and is fixedly installed on the utility model on the underframe of cushion frame by the Bowden cable support, and the other end of Bowden cable is connected with seat adjustment parts to be resetted, for example regulate cylinder and captive joint with backrest adjustment cylinder and cushion mobile device.During use, push down on the pedal, rotating shaft rotates and spurs Bowden cable on the relative pedal support of pedal, make the upper end elastic roller break away from the locking spigot surface, enter the release spigot surface, because Bowden cable connects the backrest adjustment cylinder simultaneously and mobile device is regulated cylinder, thereby realize the utility model cushion mobile device and backrest assembly, when no matter being in which kind of adjustment state, when the release pedal is stepped on, make the adjustment state of above-mentioned two assemblies be returned to initial condition at first fast, realize the rotation of pivoted frame then, and under the effect of corresponding rotary steering, realize smooth rotation.Rotation finishes and unclamps pedal, because the effect of retracing spring makes elastic roller slide to locking spigot surface and locking along the release spigot surface.
No matter the utility model can realize backrest and cushion and be under which kind of adjustment state, when stepping on the rotation pedal, can make the pivoted frame rotation and do not have interference.Have advantages such as easy and simple to handle, safe and reliable.Be specially adapted to the release and the locking of high-speed train chair rotation.
