Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be further described below with reference to the accompanying drawings.

Referring to fig. 1, a waist traction office chair includes a mounting frame 6, a seat body 3, a backrest 11, armrests 1, a body fixing component and a seat angle adjuster 7. The seat body 3 is positioned on the mounting frame 6, and the backrest 11 is arranged at one side of the seat body 3. The number of the armrests 1 is 2, and the 2 armrests 1 are respectively and fixedly arranged on the left side and the right side of the chair cushion. The armrest 1 is fixed on the seat body 3 by the armrest 1 frame, so that the comfort level of the office chair is improved.

The body-securing component includes an inner bandage 12 and an elastic bandage 13.

The inner bandage 12 and the elastic bandage 13 are divided into two sections, and a magic tape is disconnected and fixed between the two sections.

The inner bandage 12 is fixed with a first magic tape, and the elastic bandage 13 is fixed with a second magic tape. After sitting on the office chair, the two sections of bandages are fixed between the waist through the magic tapes.

The back of the bandage (inner bandage 12 and elastic bandage 13) is connected with a sliding block 10, and the sliding block 10 is pushed to slide by the air cylinder 8, so that the bandage is just between the waist.

Referring to fig. 2, the right bottom of the office chair is provided with an air bag 5, the right armrest 1 is provided with a deflation valve 14, and the air pipe 4 is connected with the air bag 5 and is connected with the air cylinder 8 through the deflation valve 14. The air bag 5 functions to inflate the air cylinder 8 and includes a hinge shaft 19, a foot plate 18, a bottom plate 21, an intake check valve 20, and the air bag 5. The hinge shaft 19 is connected with the pedal plate 18 and the bottom plate 21, the air in the air bag 5 is input into the air cylinder 8 through the air pipe 4 by pressing the pedal plate 18 by the foot, after the foot is lifted, the pedal plate 18 returns to the original position, the air enters the air bag 5 through the air inlet one-way valve 20, and the process is repeated until the bandage of the air cylinder 8 reaches the required position. If the gas is too much carelessly or the use is changed, the air release valve 14 on the handrail 1 is unscrewed, the gas is released, then the handrail is screwed down again, and the inflation process is repeated until the required effect is achieved.

Referring to fig. 3, the cylinder 8 includes an intake hole 17, a piston 16, a telescopic column 9, an exhaust hole 15 and the cylinder 8. The air pipe 4 is connected with an air inlet 17 of the air cylinder 8, when the air cylinder 8 is inflated, air pushes the piston 16 to move upwards, one end of the telescopic column 9 is connected with the piston 16 to move upwards together, the other end of the telescopic column is connected with the sliding block 10, the sliding block 10 is embedded on the backrest 11, and the telescopic column 9 pushes the telescopic column to slide up and down to adjust the position of the bandage. The exhaust hole 15 is used for communicating the piston 16 with the external atmosphere by separating the upper cavity of the cylinder 8, so that when the lower cavity of the piston 16 is filled with gas, the pressure of the upper cavity is unchanged, and the lower cavity pushes the piston 16 to move upwards for balancing the pressure.

The seat angle adjuster 7 is arranged on the right hand side of the office chair, is not different from other automobile angle adjusters, and can be released after people lean against or fall forwards according to own feeling after breaking the inclined rod, namely the angle position is fixed.

The working process is as follows:

the office chair is firstly taken, then the inclined rod of the chair regulator is pulled to adjust the angle, then the bandage is put in place by hands, the air bag 5 is stepped on by feet until the bandage reaches the proper waist position, and the bandage is stuck and fixed. When the bandage is not used for a while, the bandage can be separated after being disassembled. When the air-release valve is used by a user, the air-release valve 14 on the right handrail 1 is opened to release air, and the air-release valve is screwed down after the air release is finished.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
