Passenger seat armrest rotating device of small highway passenger car

Abstract

The invention provides a passenger seat armrest rotating device of a small highway passenger car. The passenger seat armrest rotating device comprises a rotating armrest, a disc and positioning shafts, wherein a center hole is formed in the bottom end of the rotating armrest, and two sets of rail grooves are formed in the center hole in an up-down alignment mode; the disc is fixedly connected witha fixing shaft, and the fixing shaft penetrates through the center hole to be connected with a seat back through bolts; two sets of positioning shafts are arranged in an aligned mode and fixedly connected with lifting handles, and the positioning shafts penetrate through the rail grooves to be connected with the seat back through bolts. According to the invention, two sets of rail grooves are formed in the rotating armrest in an aligned mode, a groove is formed in one end of the rail groove, and the rotating armrest can rotate around the fixing shaft by 90 degrees; when the rotating armrest is located at the highest point, the positioning shafts are moved downwards to the bottom ends of the grooves, the two positioning shafts are clamped in the grooves of the two rail grooves, and the rotating armrest is fixed; and the two sets of positioning shafts are fixedly connected with the handles, the handles can be pulled to control the two sets of positioning shafts to ascend or descend at the same time, and the operation is easy.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and more specifically relates to a rotating device for an armrest of a passenger seat of a small road passenger car. Background technique [0002] At present, my country's transportation is becoming more and more developed, and at the same time, there are more and more car accidents. Therefore, my country requires that handrails must be installed in the seat aisles of small road buses to protect the safety of passengers. At present, the existing bus handrails During the lifting process, it is easy to get stuck, and the internal mechanical structure is complicated and the cost is very high. [0003] Based on the above, the automobile rotating armrest is an essential part in small passenger cars, and has more and more extensive applications, but the mechanical structure of the current passenger car armrest is complex, the operation is more troublesome, and the failure rate is high. [0004] Ther...
