A single-lever dual-control seat tray

Abstract

The invention discloses a single-rod double-control seat tray. The single-rod double-control seat tray comprises a base used for being connected with a seat pneumatic rod and a bracket used for being connected with a seat, the base is connected with the bracket, and therefore an inner cavity of the tray is formed; a middle rod which penetrates through side plates of the bracket and can rotate is arranged in the inner cavity, and the middle rod is connected with a lifting adjusting mechanism and a leaning adjusting mechanism, wherein the lifting adjusting mechanism comprises a swing part which is connected to the bracket through a shaft, a clamping part which is arranged on the middle rod in a sleeving mode and used for driving the swing part to swing and an adjusting rod which can be freely clamped with the clamping part, the leaning adjusting mechanism comprises a vertical rod part, one end of the vertical rod part is fixed on the base, and an elastic part is connected to the other end of the vertical rod part. According to the single-rod double-control seat tray, adjustment of the seat height and leaning amplitude is achieved by adopting one rod part, the rod part is arranged on the side edge of the seat, and the defect that for a traditional seat, a person needs to squat or bend over to rotate a knob to adjust the leaning amplitude is overcome.

Description

technical field [0001] The invention belongs to the mechanical field of office chairs and swivel chairs, and in particular relates to a single-rod double-control seat tray. Background technique [0002] The seats that people use in life often need to adjust different heights and tilt angles according to the needs of different people. In order to solve this demand, people have installed a seat tray, also known as a seat chassis, under the seat cushion of the seat. The seat tray can adjust the height of the seat and the inclination range of the seat back, and has been widely used in people's daily life. [0003] Chinese patent (notification number: CN2922618) discloses a lifting and tilting chair chassis, which is composed of an upper plate, a middle plate and a knob. On the plate, a U-shaped support frame is arranged on the middle plate, the U-shaped support frame is connected to the back steel plate seat and the upper plate, the back steel plate seat is connected to the mid...

AI Technical Summary

Problems solved by technology

When adjusting the reclining force of the seat, the handle arranged on the side of the seat overcomes the defect of needing to lean over or squat down to adjust the spring tightness, but the lifting adjustment mechanism of the seat and the reclining force adjustment mechanism Work separately and independently, that is to say, the user needs to operate different levers to achieve two different adjustment purposes, which causes inconvenience to the user to a certain extent, and both functions are adjusted through the lever It is also easy to confuse users
