Abstract

The invention relates to a rotating base frame for train seats. The rotating base frame is characterized by being formed by connecting a bottom frame mechanism with a rotating frame mechanism, and the bottom frame mechanism is rotatably connected with the rotating frame mechanism; the bottom frame mechanism is formed by connecting a bottom frame welding and riveting assembly with legs arranged at the two ends of the bottom frame welding and riveting assembly; a front main beam plate and a rear main beam plate which are composed of U-shaped profiles are arranged at the two ends of the bottom frame welding and riveting assembly; a socket assembly is arranged on the side face of the bottom frame welding and riveting assembly, and a rotating bearing seat is arranged in the middle of the bottom frame welding and riveting assembly. During use, a foot stamps a side foot pedal at one end of a bottom frame, and a locking wheel on the side foot pedal is disconnected from a locking bayonet in a rotating frame, so that the demand of rotation of 180 degrees is realized. Meanwhile, the rotating base frame has the advantages of simple structure, high universality and convenience in use and can realize universality of high-speed train seats.

Description

technical field [0001] The invention relates to the technical field of train seats, in particular to a rotating base frame for train seats. Background technique [0002] At present, my country's high-speed trains use seats with rotating functions, which can rotate forward and backward by 180°. In order to make the arrangement of seats in the carriage more reasonable, and at the same time ensure the safety and comfort of the seats, and to enable passengers to maintain the same direction of travel of the train, the Ministry of Railways requires that the seats can be rotated 180° forward and backward. However, the rotating structure of the existing seat is either complicated in mechanism, heavy in material, and easy to loosen during use, resulting in a large amount of seat shaking or even rotation failure, or the defect of the rotating structure itself has a large gap, and the seat rotation caused by the transformation of the turret Defects such as faults and poor flexibility ...
