Embodiment 1

[0045] Such as figure 1 and figure 2 As shown, an adjustment control mechanism for a seat tray includes a moving plate 1, a fixed plate 2 and a base 3, the moving plate 1 is connected to the backrest of the office chair, and the fixed plate 2 is connected to the telescopic member 34 on the office chair . Telescopic part 34 can be air pressure bar (telescopic part 34 is as image 3 shown). The base 3 is connected with the seat board of the office chair. The moving plate 1 is rotatably connected to the fixed plate 2 , and the fixed plate 2 is connected to the base 3 . The inclination angle of the backrest relative to the seat board can be adjusted by turning the rotating disc 1 .

[0046] Such as Figure 4 As shown, a rotating shaft 4 is fixed on the moving disk 1 , and the two ends of the rotating shaft 4 respectively pass through the sidewalls on both sides of the fixed disk 2 and are rotatably connected to the fixed disk 2 . The rotating shaft 4 is fixedly connected t...

Embodiment 2

[0062] The difference between the second embodiment and the first embodiment is that the actuator 15 and the force application member 16 are different. Such as Figure 10 and Figure 11 As shown, the actuator 15 includes an abutment 20 and a first guide 21 , and the force application member 16 includes a second guide 25 and a force application 16 .

[0063] Such as Figure 11 As shown, the actuator 15 includes an abutment 20 and a first guide 21 . Such as Figure 10 As shown, the abutting member 20 abuts against the end of the second segment 19 facing away from the fixed plate 2 , and the abutting member 20 is slidably connected to the guide rail 11 . The abutting member 20 is circumferentially fixed relative to the guide rail 11 . Such as Figure 11 As shown, the first guide member 21 is arranged axially along the guide rail 11 and is fixedly connected to the outer wall of the abutment member 20 . Several first guide members 21 are provided around the abutment member 2...

Abstract

The invention discloses an adjusting control mechanism for a seat tray. The adjusting control mechanism comprises a fixed disc, a movable disc and a torsional spring, wherein the fixed disc is used for mounting a telescopic piece; the movable disc is rotationally connected to the fixed disc; the torsional spring is used for driving the movable disc to rotate to enable an angle between the fixed disc and the movable disc to restore to an initial angle; locking holes are formed in side walls of the movable disc; a plurality of locking holes are formed along a rotating track of the movable disc;a locking piece is connected onto the fixed disc in a sliding manner along an axial direction of the locking holes; a guide rail used for limiting a sliding direction of the locking piece is arrangedon the fixed disc; the guide rail and the fixed disc are fixed along an axial direction of the guide rail; and a driving mechanism used for driving the locking piece to deviate from or be inserted into the locking holes is arranged at one outward end of the locking piece. A seat using the seat tray has an adjustable seatback tilting angle, so that the seat can provide appropriate backrest supporting force for people of various bodily forms, and the using comfort level is improved.

Description

technical field [0001] The invention relates to office chair accessories, in particular to an adjustment control mechanism for a seat tray. Background technique [0002] At present, the working hours of office workers are generally more than eight hours, and about 60% of office workers spend their time on chairs every day.
