Abstract
The utility model relates to a rotation locking mechanism for a train seat. The rotation locking mechanism comprises a locating plate and a rotation frame. The rotation locking mechanism is characterized in that pedals and a locking block are arranged on the rotation frame, a locating pin is arranged on the locking block, and a rotation bearing is arranged on the locating plate; and the rotation frame and the rotation bearing are connected through bolt connection supports, and the locating pin and the pedals are connected through a steel wire pull rope. During usage, the seat can be rotated for 180 degrees. When the seat is rotated, an attendant steps on the pedals lightly with feet, the steel wire pull rope is pulled, the locating pin is separated from a taper lock buckle of the bottom frame locating plate, the seat rotation frame is in a rotatable state, and after the locating pin rotates through the lock buckle, the attendant can loosen the feet, so that the good reliability and safety is provided. Simultaneously, the structure is compact, occupied space is small, arrangement of seat equipment is facilitated, and accordingly, the seat bottom frame size is reduced, and moving space for legs and feet of passengers is increased.
Description
Technical field
The utility model relates to the technical field of train seat, specifically a kind of revolution lockout mechanism for train seat.
Background technology
At present, in order to satisfy the passenger to the requirement of traveling comfort, High Speed Train in China installs back the swivel base chair mostly, makes the passenger all the time towards This train is bound for XXX, has avoided the passenger to produce the uncomfortable reactions such as carsick.And the revolution lockout mechanism of existing seat is arranged on underframe more, after using a period of time, due to the distortion of pivoted frame or underframe, easily produces and interferes, and turns round simultaneously lockout mechanism and takes up room greatlyr, affect the layout that seat is equipped.
Summary of the invention
The purpose of this utility model is to provide a kind of improved revolution lockout mechanism for train seat, it can overcome in prior art the distortion due to pivoted frame or underframe, easily produce and interfere, turn round simultaneously lockout mechanism and take up room greatlyr, affect the some shortcomings of the layout that seat equips.
To achieve these goals, the technical solution of the utility model is: the revolution lockout mechanism that is used for train seat, it mainly comprises locating plate and pivoted frame, it is characterized in that: pivoted frame is provided with step and lock dog, described lock dog is provided with locating dowel pin, locating plate is provided with swing bearing, is bolted supporting between pivoted frame and swing bearing and is connected, and is connected by wire digging line between locating dowel pin and step.
During use, the utility model can make seat realize 180 degree rotations, during rotation, bus attendant is gently stepped on step on pivoted frame with pin, pulls wire digging line, makes locating dowel pin break away from the taper snap close of underframe locating plate, seat rotating stand just is in rotatable state, after locating dowel pin turned over snap close, bus attendant just can unclamp pin, had reliability and safety preferably.This apparatus structure is compact simultaneously, takes up room less, is convenient to the layout of seat equipment, the seat bottom support body is amassed dwindle, and has increased the activity space of passenger's legs and feet.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the structural representation of the another embodiment of the utility model.
Fig. 3 is lock block structure schematic diagram of the present utility model.
Fig. 4 is dispersed texture schematic diagram of the present utility model.
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
In each accompanying drawing, mark is expressed as follows: 1 locating plate, 2 rotary blocks, 3 swing bearings, 4 locating dowel pins, 5 recoil press springs, 6 packing rings, 7 wire digging lines, 8 lock dogs, 9 bearing pins, 11 pivoted frames, 12 rotating shafts, 13 steps.
Revolution lockout mechanism for train seat described in the utility model, it mainly comprises locating plate and pivoted frame, its difference with the prior art is: pivoted frame is provided with step and lock dog, described lock dog is provided with locating dowel pin, locating plate is provided with swing bearing, be bolted supporting between pivoted frame and swing bearing and be connected, be connected by wire digging line between locating dowel pin and step.Locating dowel pin is provided with return jump ring and packing ring, and described gasket sleeve is located on locating dowel pin, and an end of return jump ring contacts with packing ring, and the other end contacts with lock dog, locating dowel pin with lock dog for slidably being connected.Described locating plate is provided with rotary block, and rotary block adopts chloroprene rubber material to make.Pivoted frame is provided with rotating shaft, and step forms by rotating shaft and pivoted frame and is rotatably connected, and lock dog is captiveed joint with pivoted frame by bolt.
In enforcement, when seat needed 180 degree rotation, bus attendant was gently stepped on step 13 on pivoted frame 11 with pin, pulls wire digging line 7, makes locating dowel pin 4 break away from the taper snap close of underframe locatings plate 1, and seat rotating stand 11 just is in rotatable state; After locating dowel pin 4 turned over snap close, bus attendant just can unclamp pin; When locating dowel pin 4 is in the a-quadrant, locating dowel pin 4 is no longer located with underframe, 1 contact, when locating dowel pin enters the B zone, due to the 1 contour shape effect of underframe locating plate, locating dowel pin 4 makes locating dowel pin 4 produce enough large power and enters underframe locating plate 1 snap close by E type jump ring 5 and packing ring 6 compression retracteding position springs 5, and seat rotating stand 11 is locked; Rotary block 2 has played buffer action simultaneously, alleviates the impact of 11 pairs of underframe locatings plate 1 of seat use procedure transfer rack.
