At present, when most chairs are placed, because the ground and the base are hard objects, when office workers sit on the chairs to slide, when the chairs meet uneven ground, the chairs bump greatly, the comfort level of the chairs is poor, and the impact of the uneven ground can cause great abrasion to the chair wheels.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a double damping office chair with reasonable structure and good use effect.
In order to achieve the above object, the present invention provides a technical solution: a double-damping office chair comprises a base and a traveling wheel, wherein the bottom of the base is provided with a mounting groove with an n-shaped vertical section, a mounting plate is arranged in the mounting groove, the base at the edge of the bottom of the mounting groove horizontally shrinks inwards to form a limit edge, the bottom of the mounting plate is limited by the limit edge, a base damping spring is arranged in the mounting groove above the mounting plate, the top of the base damping spring is abutted against the base at the top of the mounting groove, the bottom of the base damping spring is abutted against the top of the mounting plate, the bottom of the mounting plate is vertically provided with a mounting rod, the bottom of the mounting rod penetrates downwards to be connected with the traveling wheel through the mounting groove, the top of the base is vertically provided with a lifting cylinder, the top of the lifting cylinder is provided with a lifting plate, a chair cushion mounting seat is arranged above the lifting, the bottom of the guide screw penetrates through the lifting plate downwards to form an adjusting end, an adjusting nut is connected to the adjusting end, a mounting seat damping spring is sleeved on the guide screw between the lifting plate and the seat cushion mounting seat, the top of the mounting seat damping spring is abutted to the bottom of the seat cushion mounting seat, the bottom of the mounting seat damping spring is abutted to the top of the lifting plate, the seat cushion is mounted at the top of the seat cushion mounting seat, back frames are fixed on two sides of the seat cushion mounting seat, and a back is mounted between the upper portions of the two back frames.
The bottom of the chair cushion mounting seat is provided with an inwards concave thread groove, and the upper part of the guide screw is connected in the thread groove.
The top of the lifting cylinder is provided with a rotating seat through a rotating bearing, and the lifting plate is fixedly arranged at the top of the rotating seat.
After the scheme is adopted, the buffering height of the base damping spring is 1-3cm, when office workers sit on the chair to slide, when the chair meets uneven ground, the base damping spring at the position buffers for one time, and the cushion mounting seat buffers the human body again through the mounting seat damping spring (falling force and impact force), so that the bumpiness during moving is reduced, and the abrasion of the uneven ground to the chair wheel is also reduced; the buffering force of the seat cushion mounting seat can be adjusted by screwing or unscrewing the adjusting nut; rational in infrastructure, excellent in use effect after this scheme of adoption.
