The specific embodiment
As shown in Figure 1, a kind of Chain cushion of the utility model moves and latching device, comprises a back frame 1 that is fixedly mounted on the underframe 3, and back frame 1 is formed by connecting by back frame 110 and under(-)chassis 100 one.Seat basin stand 2 can slide along under(-)chassis 100 front and back, under(-)chassis 100 internal fixation have tooth bar 5, seat basin stand 2 be provided with can with these tooth bar 5 mating teeth bar latching devices 4, when tooth bar latching device 4 was meshed with tooth bar 5, basin stand 2 just was fixed on the under(-)chassis 100.
In conjunction with reference to Fig. 2, under(-)chassis 100 by left and right rail brackets 102,102 ' and front and rear connecting rods 103,103 ' be welded, captive joint with front and rear connecting rods 103,103 ' respectively in the two ends of tooth bar 5.Left and right rail brackets 102,102 ' inboard are fixed with left and right slippage guide rail 101,101 ' respectively.
Seat basin stand 2 is by left and right bogie side frame 202,202 ' and the framework that is welded of forward and backward pipe 203,203 ', be respectively equipped with first, second pivot pin 201,201 ' on the left and right bogie side frame 202,202 ', insert respectively in the left and right slippage guide rail 101,101 ' first, second pivot pin 201,201 ' end, and first, second pivot pin 201,201 ' end are provided with the roller (not shown), this roller can roll in left and right slippage guide rail 101,101 ', thereby a basin stand 2 is slided along under(-)chassis 100 front and back.
Tooth bar latching device 4 is installed on the present basin stand 2, and tooth bar latching device 4 is made up of bolt axle 401, locking 402, lock shaft 403 and unlocking board 404.Wherein the two ends, the left and right sides of lock shaft 403 are bearing in respectively on the left and right bogie side frame 202,202 ', and can rotate; Be fixed on a side of lock shaft 403 for locking 402, unlocking board 404 is fixed on the lock shaft 403 and locking 402 relative opposite side, and 401 of bolt axles are fixed on locking 402, and bolt axle 401 embeds in the teeth groove of tooth bar 5, at this moment, seat basin stand 2 is locked, and can not slide along guide rail.
Left side frame 202 ' is provided with to the outstanding extension spring hook 212 in unlocking board 404 tops, is connected with an extension spring (not shown) between extension spring hook 212 and unlocking board 404.When pressing unlocking board 404 downwards, drive lock shaft 403 and rotate, make locking 402 of offside to be upturned, bolt axle 401 is deviate from tooth bar 5.When pinning unlocking board 404, drag a basin stand 2 then forward, the rolling in left and right slippage guide rail 101,101 ' of the roller of seat on the basin stand 2, tooth bar latching device 4 is also along with moving forward.After reaching the distance of feeling suitable, unclamp unlocking board 404, under the effect of extension spring, lock shaft 403 automatically resets, and then bolt axle 401 embeds in the teeth groove of tooth bar 5 once more, makes a basin stand 2 lockings.
The utility model is paid and mobile guide by symmetrically arranged slip, can realize easily that cushion moves, problems such as the part running of having avoided factors such as unbalance stress to cause is dumb, reduction in service life; By adopting cooperating of tooth bar and tooth bar latching device, can realize the locking of cushion easily, and cushion realization classification is moved, satisfy the demand of train seat traveling comfort.
