Problems solved by technology

However, in order to realize the positioning of the armrest, the positioning block can only rotate on the fan-shaped concave position, resulting in the armrest can only rotate within a certain angle, and cannot rotate 360 ​​degrees. At the same time, because there is no locking function, the armrest body Stable positioning cannot be achieved after rotation

Abstract

The invention discloses a rotatable armrest assembly with a locking function. The rotatable armrest assembly comprises a support seat and an armrest body rotatably arranged on the support seat, the armrest body and the support seat are connected through a rotating shaft, the rotating shaft is sleeved with a gear capable of sliding at the bottom of the armrest body, and the bottom of the armrest body is provided with a first sliding groove for containing the gear; the support seat is provided with a locking part for controlling the armrest body to rotate, the locking part comprises a spring bolt capable of stretching into tooth grooves of the gear and a push part which is in wedged connection with the spring bolt, the end face, facing the armrest body, of the gear is provided with first protrusions, and the armrest body is provided with first concave portions matched with the first protrusions. According to the rotatable armrest assembly, by connecting the armrest body with the rotating shaft arranged on the support seat, the armrest body can rotate in 360 degrees, and by arranging the locking part on the support seat, the armrest body achieves the locking function.

Description

technical field [0001] The invention relates to an armrest, in particular to a rotatable armrest assembly with a locking function. Background technique [0002] With the development of social economy and the improvement of living standards, the people's pursuit of life is getting higher and higher. In daily life, in order to improve the comfort of the seat, armrests will be provided on the left and right sides of the seat. Although in the prior art Adjustable armrests exist, but these adjustable armrests have drawbacks. [0003] For example, Chinese patent CN201208078Y discloses a multi-functional seat armrest, wherein the positioning block at the bottom, the movable box seat that can slide and rotate, the upper sliding positioning block and the rotating positioning block are connected into one body through anti-loosening bolts to form a Movement mechanism that can rotate left and right. However, in order to realize the positioning of the armrest, the positioning block can...
