Abstract
The utility model relates to a backrest unlocking reset synchronous mechanism for a track traffic vehicle steerable seat. The backrest unlocking reset synchronous mechanism comprises a side pedal assembly. The side pedal assembly is connected with a control switch of a gas spring driving a seat backrest to reset through a steel wire rope. The side pedal assembly comprises a mounting base, a side pedal and a two-connecting-rod device. The side pedal is installed on the mounting base through a rotating shaft. The mounting base is mounted to the outer side of a fixed bottom frame. The side pedal pulls the steel wire rope through the two-connecting-rod device. The side pedal resets through a reset spring. One connecting rod of the two-connecting-rod device is connected with the side pedal. The other connecting rod of the two-connecting-rod device is connected with the steel wire rope and rotates around a pin shaft fixed to the mounting base. The backrest unlocking reset synchronous mechanism for the track traffic vehicle steerable seat has the advantages that the seat backrest resets when rotation locking of the seat is removed, the operating stroke of the side pedal is shortened through the two-connecting-rod device, the seat backrest can reset easily with small operating force, and the physical power of a trainman is saved.
Description
Technical field
The utility model relates to a kind of rail traffic vehicles and can turn to the backrest release reset synchronization mechanism of seat.
Background technology
High speed train, because running velocity is fast, needs passenger's seat direction consistent with current of traffic, avoids oppositely taking the discomfort causing.Therefore high-speed train chair need to increase turning function, after train arrives the destination stop of traffic coverage when return, can be seat Rotate 180 °, and make seat continue to be consistent with current of traffic.In seat when rotation commutation, because interior space is limited, need to be after first resetting in the backrest that uses state, then remove the lockout mechanism of rotary seat, start rotary seat.
The limited time of train commutation, regulates the button of the backrest seat that resets too to bother with passenger, carrys out rotary seat after reset seat again, and whole operating process is oversize.
The Chinese utility model patent of notification number CN201613901U discloses a kind of one and has stepped on return mechanism, comprise side step assembly, steel rope and backrest gas spring, side step assembly is by zip control backrest gas spring, back of seat is resetted, and the passenger's button that no longer needs train attendant to operate respectively each seat resets back of seat.But this one is stepped on return mechanism and pulls zip by the step zip axle on side step top, causes side step operational stroke long, and operating effort is large, and train attendant is easily tired.
Utility model content
Technical problem to be solved in the utility model is: the backrest release reset synchronization mechanism that provides a kind of rail traffic vehicles can turn to seat, and shorten batter and step on operational stroke, reduce the operating effort that batter is stepped on.
The utility model solves the technical scheme that its technical matters adopts: a kind of rail traffic vehicles can turn to the backrest release reset synchronization mechanism of seat, comprise that batter steps on assembly, batter is stepped on assembly and is connected with the master cock of the gas spring that drives back of seat to reset by steel rope, batter is stepped on assembly and is comprised mount pad, batter is stepped on and two linkages, batter is stepped on by S. A. and is arranged on mount pad, mount pad is arranged on the outside of fixed frame, batter is stepped on by two linkages and is pulled steel rope, batter is stepped on by retracing spring and is resetted, a connecting rod of two linkages is stepped on and is connected with batter, another connecting rod is connected with steel rope, this connecting rod being connected with steel rope is around the bearing pin rotation being fixed on mount pad.
Set foot on the locking pin having by the corresponding locking recess locking rotating frame on embedded rotating framework at batter.
Retracing spring is arranged between two linkages and mount pad, and is connected with two linkages and mount pad respectively.
The beneficial effects of the utility model are: in the spin locking of release seat, control block chair back resets, and shorten by two linkages the operational stroke that batter is stepped on, adopt less operating effort can easily make back of seat reset, saved train attendant's muscle power.

Detailed description of the invention
As shown in Fig. 1,2,3 and 4, a kind of rail traffic vehicles can turn to the backrest release reset synchronization mechanism of seat, comprise that batter steps on assembly 1, batter is stepped on assembly 1 and is connected with the master cock 51 of the gas spring 5 that drives back of seat 4 to reset by steel rope 6, master cock 51 is double control switch, master cock 51 is connected with the button being arranged on armrest by another steel cable, and passenger can control by button the switch of gas spring, thus adjusting seat backrest.
Batter is stepped on assembly 1 and is comprised that mount pad 12, batter step on 11 and two linkages 15, batter is stepped on 11 and is arranged on mount pad 12 by S. A. 14, mount pad 12 is arranged on the outside of fixed frame 2, batter is stepped on 11 and is pulled steel rope 6 by two linkages 15, batter is stepped on 11 and is resetted by retracing spring 16, retracing spring 16 is arranged between two linkages 15 and mount pad 12, and is connected with two linkages 15 and mount pad 12 respectively.A connecting rod of two linkages 15 is stepped on 11 with batter and is connected, and another connecting rod is connected with steel rope 6 by the steel rope anchor shaft 17 on connecting rod, and this connecting rod being connected with steel rope 6 is around the bearing pin rotation being fixed on mount pad 12.
Step on the corresponding locking recess 31 having on 11 on the rotating frame 3 by embedding seat and lock the locking pin 13 of rotating frame 3 at batter.
In the time that bus attendant depresses batter and steps on 11, batter is stepped on 11 drive locking pins 13 and is departed from the locking recess 31 on rotating frame 3, and while batter steps on 11 promotion two linkages 15 and steel rope anchor shaft 17 moves, thereby pulls steel rope 6, open the master cock 51 on gas spring 5, back of seat 4 is resetted.
