The locking washer has locking and stopping functions and prevents the handrail from shaking laterally.
Furthermore, a clip is arranged on the rotating shaft, so that the mounting base is in interference fit with the rotating shaft through the clip.
Further, the fixed ratchet wheel is connected with the rotating shaft in an interference fit mode.
Furthermore, the mounting base is a metal casting, and the fixed ratchet wheel and the rotating ratchet wheel are steel pieces.
Furthermore, the elastic part of the clamp can perform displacement compensation and has a certain anti-loosening function; the handrail framework is a plastic part, is formed by injection molding, and is internally provided with a reinforcing rib and a weight reduction groove.
Furthermore, the automobile armrest is provided with three gear adjusting positions in the horizontal position, and each gear is separated by 7 degrees.
By adopting the structure, the handrail realizes multi-gear adjustment through fewer parts, and has the technical advantages of simple structure, convenience in operation and control, easiness in realization of products, long service life and the like. Meanwhile, the handrail framework is directly arranged on the rotating shaft, so that the rotating shaft of the handrail can be effectively prevented from falling off.
