Example Embodiment

[0051]Example 1:

[0052]Such asFigure 1 to 3As shown, a multifunctional adjustment device of a swivel chair chair, comprising a housing 1 and a back mounting plate 2, and the back mounting plate 2 is hinged by the main pin shaft 21 on the housing 1, the back mounting plate 2 An elastic assembly 4, an adjustment assembly 5, and a propeling block 6 are provided in the housing 1, including a first spring 41 and a second spring. 42. One end of the first spring 41 and one end of the second spring 42 together abut the adjustment assembly 5, the adjustment assembly 5 adjusts the first spring 41 and the second spring 42 angle, the The other end of the first spring 41 and the other end of the second spring 42 are commonly hinged on one side of the propulsion block 6, the propulsion block 6 is arranged on the top direction shaft 22.

[0053]Further, an angle adjustment assembly 3 includes:

[0054]The adjustment board 31 is sleeved in the main pin shaft 21 and the top-carry shaft 22, the adjustment p...

Example Embodiment

[0067]Example 2:

[0068]For the sake of simplicity, only the distinction points of Embodiment 2 and Example 1 are described below; this embodiment 2 is different from that of Example 1 is:

[0069]Such asFigure 4 As shown in the present embodiment, the moving member B55 is further included, the moving member B55 is arranged on the screw 53, the screw 53 being inversely rotated to drive the moving parts B55 up and down reciprocating motion, the movement The member B55 hinges the second spring 42 to vary the second spring 42 opposite the first spring 41 angle.

[0070]Further, one end of the screw 53 is set to a right-thread, and the other end is set to the left-handed thread.

[0071]Specifically, the moving member B55 is quickly adjusted to the second spring 42 relative to the first spring 41, so that the elastic force of the back mounting plate 2 is larger, faster adjustment.

Example Embodiment

[0072]Example 3:

[0073]For the sake of simplicity, only the difference points of Example 3 and Example 1 or Example 2 are described below; this embodiment 3 is different from that of Example 1 or Example 2 is:

[0074]Such asFigure 5 ,6As shown in the present embodiment, the number adjustment unit 1 56 is further included, and the number adjustment unit 1 56 is disposed in the end of the first spring 41 to elastically adjust the first spring 41. The ring number adjusting unit 1 56 includes a connecting member 561, a rotary drive wheel A562, a rotary drive wheel A562, a lever 563, and a partition member 564, which connects the first spring 41 and the moving member A54, the turn rod 563 rotation Set in the connector 561, the housing 1 inner wall is provided with a rack 12, and the rotary drive wheel A562 is engaged with the rack 12, and the rotary drive wheel A562 drives the rotor 563 to rotate. The spacer 564 is disposed at the end of the passage 563, the separator 564 inserts into the g...

Abstract

The invention relates to the technical field of swivel chairs, in particular to a multifunctional adjusting device for a swivel chair chassis and a using method thereof.The device comprises a shell and a backrest mounting plate, the backrest mounting plate is hinged to the shell through a main pin shaft, a jacking shaft parallel to the main pin shaft is arranged on the backrest mounting plate, and an elastic assembly, an adjusting assembly and a pushing block are arranged in the shell; the elastic assembly comprises a first spring and a second spring, one end of the first spring and one end of the second spring jointly abut against the adjusting assembly, and the adjusting assembly adjusts the included angle between the first spring and the second spring; the method comprises the following steps: step 1, an unlocking process; step 2, an elastic adjustment procedure, wherein the procedure comprises included angle adjustment and effective turn number adjustment; and 3, a lifting adjustment procedure. The included angle between the first spring and the second spring is rapidly adjusted through the adjusting assembly, meanwhile, the adjusting method of the unlocking procedure, the elastic adjusting procedure and the lifting adjusting procedure is matched with included angle adjustment and effective turn number adjustment, adjustment is rapid, and elasticity is large.

Description

technical field [0001] The invention relates to the technical field of swivel chairs, in particular to a multifunctional adjustment device for a swivel chair chassis and a method for using the same. Background technique [0002] The swivel chair tray, also known as the swivel chair chassis, is an important part installed under the swivel chair seat cushion, which can realize the lifting of the seat cushion and the adjustment of the tilt angle of the backrest. The current swivel chair tray is generally composed of a tray body, a seesaw, a rotating shaft, and a spring device. The seesaw is fixed to the back of the swivel chair seat. There is comfort. The elastic force of the existing swivel chair backrest is not large enough, and the adjustment is troublesome. [0003] Patent No. CN201410479184.4 discloses a seat back rocker locking mechanism for swivel chair chassis, including a locking plate, a torsion spring a, a latch and a latch seat, a row of lock holes is arranged on ...
