Safe lifting chair

Abstract

The invention discloses a safe lifting chair. The safe lifting chair comprises a cushion, a tray, a pneumatic rod and chair feet, the safe lifting chair is characterized in that an anti-explosion steel plate is arranged above a connection hole of the tray, an arc guiding board is arranged below the anti-explosion steel plate, an inner sleeve is arranged on the upper surfaces of the chair feet, andan outer sleeve is arranged under the tray. According to the safe lifting chair, through the inner sleeve and the outer sleeve which are matched, damage of lateral gas pressure impact force to humanbody legs when the pneumatic rod explodes is prevented, and meanwhile, through the anti-explosion steel plate and the arc guiding board which are matched, damage of forward upward impact force and parts to human body hips when the pneumatic rod explodes is prevented.

Description

Technical field [0001] The invention relates to the technical field of sitting equipment, in particular to a safety lift chair. Background technique [0002] Lifting office chair is a kind of chair often used in office places. Because it is convenient and comfortable to use, many families are also using lifting office chairs. The lifting mechanism of the lifting office chair is implemented by air pressure rods. Filling with nitrogen can prevent combustion during an explosion, but because the built-in pressure of the pressure rod is equivalent to 24 atmospheres, once an explosion occurs, its destructive power is equally strong. The tray of the existing office chair is located on the top of the pressure rod There is a hole on the top. Once an explosion occurs, the air pressure and fragments generated by the explosion will directly rush up, resulting in human body injury. The prior art uses steel plates to plug the holes in the tray, although the frontal rushing debris and direct im...

[0002] The lift-type office chair is a kind of chair that is often used in the office. Because it is convenient and comfortable to use, many families are also using the lift-type office chair now. The lifting mechanism of the lift-type office chair is implemented by a pneumatic rod. Filled with nitrogen, although it can prevent combustion during an explosion, but because the air pressure built into the air pressure rod is equivalent to 24 atmospheres, so once an explosion occurs, its destructive power is as strong. The tray of the existing office chair is located on the top of the air pressure rod There is a hole above. Once an explosion occurs, the air pressure and debris generated by the explosion will directly rush up, causing serious injury to the human body. In the prior art, the hole of the tray is blocked with a steel plate, although it prevents the debris and the impact force from directly rushing up. Damage to the human body, but the scattered parts will scatter from the side of the tray after being blocked by the steel plate, and the fragments scattered to the front will directly damage the legs of the human body. Since the position of the tray is close to the knee of the human body, if the scattered fragments are inserted into the knee, It is easy to cause ligament injury at the knee, causing equally significant trauma
