Problems solved by technology

[0002] The chassis of the swivel chair is an important part installed under the seat cushion of the swivel chair. The lifting of the seat cushion and the adjustment of the tilt angle of the backrest are all done by the chassis; Restrictions, the backrest tilt angle adjustment has levels, currently only two to five levels of adjustment can be achieved, that is to say, it can only be adjusted at a few predetermined angles, and because people's heights are different, each person has different adjustments to the backrest. The feeling of angle comfort is also different, so it can't meet everyone's needs

Embodiment 1

[0027] Embodiment 1: a kind of swivel chair chassis, such as Figure 1 ~ Figure 3 Shown, comprise upper cover 1, lower cover 2 that cover mutually, be provided with a rubber spring in the space that upper and lower cover 1, 2 form, as figure 1 , figure 2 , Figure 6 , Figure 7 As shown, the rubber spring includes a main shaft 3 for connecting the seat back, and a rubber layer 4 is fixed on the outer circumference of the main shaft 3, and the two ends of the main shaft 3 are exposed outside the rubber layer 4, and are fixedly sleeved outside the rubber layer There is a cylindrical shell 5, the outer contour of the rubber layer 4 and the cross section of the cylindrical shell 5 is circular, the main shaft 3 and the cylindrical shell 5 are made of metal materials; the processing process of the rubber spring is: the main shaft 3 and the cylindrical shell The cylindrical shell 5 is placed in the mould, the main shaft 3 is at the position of the central axis of the cylindrical ...

Embodiment 2

[0032] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the cylindrical shell is fixedly connected with the upper and lower covers in the circumferential direction; in this way, the rubber spring can also play a role, so that the cylindrical shell does not rotate There are also various forms. For example, its shape can be changed to other shapes except circular, so that the upper and lower covers can be closed; connecting ears can also be set on the cylindrical shell, and the connecting ears can be connected with the connecting rod through the connecting rod. The upper cover is connected and fixed, and so on.

Abstract

The invention discloses a chassis of a revolving chair, which comprises an upper cover and a lower cover, wherein a rubber spring is arranged in a space formed by the upper and lower covers, the rubber spring comprises a spindle, a rubber layer is fixedly arranged on the spindle along a circumferential direction, and a cylindrical shell is fixedly sleeved outside the rubber layer; and the cylindrical shell is connected with a connecting lug which is connected with one end of a connecting rod, and the other end of the connecting rod passes through the upper cover to be connected with a regulating knob. In the invention, the chassis uses the rubber spring as a core part, the two ends of the spindle of the rubber spring are connected with a backrest through the connecting rod, the backrest, when leaned against by a user, applies a certain force onto the spindle through the connecting rod to drive the spindle to rotate a certain angle, the cylindrical shell of the rubber spring is fixed and motionless, and thus, the rotation of the spindle makes the rubber layer generate a torque force, which increases with the increase in the rotation angle of the spindle and can drive the spindle and the backrest to reset to realize regulation at any angle.

Description

technical field [0001] The invention relates to a swivel chair, in particular to a swivel chair chassis. Background technique [0002] The chassis of the swivel chair is an important part installed under the seat cushion of the swivel chair. The lifting of the seat cushion and the adjustment of the tilt angle of the backrest are all done by the chassis; Restrictions, the backrest tilt angle adjustment has levels, currently only two to five levels of adjustment can be achieved, that is to say, it can only be adjusted at a few predetermined angles, and because people's heights are different, each person has different adjustments to the backrest. The feeling of angle comfort is also different, so it cannot meet everyone's needs. Contents of the invention [0003] The present invention overcomes the deficiencies in the above-mentioned prior art, and provides a swivel chair chassis that can realize stepless adjustment and lock at any position, so that the backrest can be adjus...
