Abstract
The utility model relates to the upset of a kind of handrail for train seat and stop gear, it mainly comprises central bracket, it is characterized in that: the side of central bracket is provided with middle armrest body, the both sides of middle armrest body are respectively equipped with symmetrically arranged left rear frame and right rear frame, are provided with a block between left and right rear frame.During use, respectively there is 1 plastic washer middle armrest body assembly and the middle both sides of central bracket, and screw passes middle armrest assembly, central bracket and plastic washer, by cover type nut lock screw.Middle armrest body assembly rotates around screw, wherein plastic washer plays shock damping action, excessively loose when preventing middle armrest body assembly from rotating, by adjustment screw and cover type nut locking force, be unlikely to tension when armrest body assembly rotates in guarantee, during rotation, need very large power.
Description
Technical field
The utility model relates to the technical field of train seat, specifically a kind of upset of the handrail for train seat and stop gear.
Background technology
At present, train seat is all provided with handrail, passenger is facilitated to use, increase the traveling comfort of passenger, armrest structure for chair has fixing also to be had turnover, and fixed armrest seat can not overturn due to handrail, is unfavorable for that passenger passes in and out, and occupy the wide size of certain seat, but the armchair structure that is relatively fixed is fairly simple.Upset handrail seat can be used for passenger to select the need of handrail function, and does not affect the turnover of passenger, and ensure that the wide size of seat is unaffected, but upset armrest seat structure of chair and stop gear relatively complicated, part comparison is many.
Summary of the invention
The purpose of this utility model is the upset of the handrail for train seat and the stop gear that provide a kind of improvement, and it can overcome current upset armrest mechanism more complicated in prior art, the some shortcomings that part comparison is many.
To achieve these goals, the technical solution of the utility model is: a kind of upset of the handrail for train seat and stop gear, it mainly comprises central bracket, it is characterized in that: the side of central bracket is provided with middle armrest body, the both sides of middle armrest body are respectively equipped with symmetrically arranged left rear frame and right rear frame, are provided with a block between left and right rear frame.
During use, respectively there is 1 plastic washer middle armrest body assembly and the middle both sides of central bracket, and screw passes middle armrest assembly, central bracket and plastic washer, by cover type nut lock screw.Middle armrest body assembly rotates around screw, wherein plastic washer plays shock damping action, excessively loose when preventing middle armrest body assembly from rotating, by adjustment screw and cover type nut locking force, be unlikely to tension when armrest body assembly rotates in guarantee, during rotation, need very large power.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the dispersed texture schematic diagram of the utility model one embodiment.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
The label of each accompanying drawing is expressed as follows: 1. left rear frame 5. block 6. of armrest body 2. screw 3. plastic washer 4. right rear frame 7. central bracket 8. cover type nut in.
A kind of upset of the handrail for train seat described in the utility model and stop gear, it mainly comprises central bracket, itself and prior art are distinguished and are: the side of central bracket is provided with middle armrest body, the both sides of middle armrest body are respectively equipped with symmetrically arranged left rear frame and right rear frame, are provided with a block between left and right rear frame.
Be interconnected by screw with the plastic washer of screw fit and cover type nut between described central bracket, middle armrest body and left and right rear frame.Described block is limiting stopper, and the side of this limiting stopper is arc surface structure, and opposite side is planar structure.Described left and right rear frame and block are welded as a whole, and are riveted together between left and right rear frame by countersunkrivet, and the external side end of left and right rear frame is circular arc end face.The upper end of central bracket is provided with a limit stops boss.
In enforcement, described left rear frame, right rear frame are symmetrical member, have 5 countersunkrivet holes above, 1 screw mounting hole, 1 block mounting hole.Described block is limiting stopper one end is arc surface, and one end is plane.Middle armrest body is aluminum alloy die casting, and both sides, end have 5 rivet holes respectively, and plastic washer is PA material, and it act as shock damping action, and screw is the flat dish screw of interior hexagonal of M8, and central bracket is Forging Parts, and there is individual limit stops boss its upper end.Cover type nut is used for lock screw on the one hand, on the one hand outstanding screw is blocked, plays decoration function.
Left rear frame, right rear frame and block are welded as an assembly, then be riveted together by countersunkrivet with middle armrest body, be combined into middle armrest body assembly, middle armrest body assembly, plastic washer is arranged in central bracket respectively successively, central bracket is fixed, screw is each passed through this 3 assemblies from one end, other end cover type nut is locked, after installing (see accompanying drawing 1), handrail is horizontality, we call handrail nadir this position, when this state the horizontal surface of block and central bracket limit stops boss face bonded to each other, middle armrest body assembly cannot be fallen, keep level attitude, when turning on handrail needs, armrest body assembly rotates around screw, when armrest body assembly rotate contact to the another side of block with central bracket time, armrest body assembly cannot turn over upper, now handrail peaks, wherein plastic washer is between middle armrest body assembly and central bracket, plastic washer passes through the locking of screw and nut and middle armrest body assembly, central bracket fitting together tightly, maintain static, in the middle of armrest body assembly when rotating around screw and plastic washer friction generation damping, the dynamics of handrail in rotation can be adjusted by the tightness adjusting screw.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that the utility model is specifically implemented to be confined to these explanations above-mentioned.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
