Abstract

The invention provides a seat turnover device for a movable stand. The seat turnover device comprises a pull rod mechanism and a position clamping mechanism, wherein one end of the pull rod mechanism is connected with an externally arranged rear-row seat platform in a sliding manner, and the other end of the pull rod mechanism is movably connected with a front-row seat; the position clamping mechanism is located between the front-row seat and the rear-row seat platform; the lower end of the position clamping mechanism is in frictional connection with the bottom of the front-row seat; the upper end of the position clamping mechanism is located on the sliding track of the rear-row seat platform; owing to the pull rod mechanism, the front-row seat can be turned over when the rear-row seat platform slides backwards; the position clamping mechanism can realize frictional limitation after the front-row seat is turned over; limitation on the front-row seat from the position clamping mechanism can be removed when a rear-row seat slides forwards; linkage between movement of the rear-row seat platform and turning of the front-row seat is mechanically realized.

Description

technical field [0001] The invention relates to the technical field of flipping seats in stands, in particular to a flipping device for seats in a movable stand. Background technique [0002] At present, there are mainly two ways to turn over the seats on the event stands: one is to turn over by the operator, and only turn over one seat at a time. This operation method requires a lot of manual work and takes a very long time; The other is to turn over a row of seats at a time by manual or electric means. Although it can reduce a lot of manual operations and save a lot of time, it still requires more time and workload. For the movable grandstand that can be linked by multiple rows, it includes front seats, a front seat platform and a rear seat platform that are slidably connected to each other, and a front seat base, and the front seats are rotatably connected to the front seat platform , the front seats are rotatably connected to the front seat base, the front seat base is ...
