Student desk for anti-seismic risk-avoiding safety

Abstract

The invention discloses a student desk for anti-seismic risk-avoiding safety. The student desk includes a desk body, a chair bracket and a seat cushion, the bottom end of the desk body is fixedly connected with a mobile guide device, and the fixed end of the mobile guide device is fixedly connected with the outer side of the bottom end of the chair bracket. According to the student desk for anti-seismic risk-avoiding safety, a lifting supporting device arranged at the bottom end of the chair bracket and the seat cushion are mutually and cooperatively used, when an earthquake occurs, the lifting supporting device drives the seat cushion to move downward in the vertical direction, students can move vertically and downward without deviating from the seat cushion, the phenomenon that the students cannot quickly hide in the bottom end of the desk body due to the fact that the backward pushing range of a seat is limited when the distance between the desk and the desk is relatively close is prevented, when the seat cushion moves to the bottom end of the chair bracket, the students quickly move to the bottom end of the desk body, and then the effect that the students quickly hide in the bottom end of the desk body for effective anti-seismic risk-avoiding is realized.

Description

technical field [0001] The invention relates to the technical field of student desks for earthquake resistance and safety avoidance, in particular to a student desk for earthquake resistance and risk avoidance safety. Background technique [0002] At present, the existing desks for students are relatively single in structure, and the student desks are reinforced at the supporting legs. However, an earthquake is an emergency, and it takes only a few seconds from the prediction of the earthquake to the occurrence of the earthquake. Moreover, the existing earthquake prediction technology is immature, and when students use desks, they are usually used in conjunction with chairs. When an earthquake occurs, students need to stand first, push the chairs behind them, and then hide under the desks. When the distance between the desks is relatively short, the backward push range of the seat is limited, making it difficult for students to hide under the desks, and it is easy to cause p...

[0002] At present, the existing desks for students are relatively single in structure, and the student desks are reinforced at the supporting legs. However, an earthquake is an emergency, and it takes only a few seconds from the prediction of the earthquake to the occurrence of the earthquake. Moreover, the existing earthquake prediction technology is immature, and when students use desks, they are usually used in conjunction with chairs. When an earthquake occurs, students need to stand first, push the chairs behind them, and then hide under the desks. When the distance between the desks is relatively short, the backward push range of the seat is limited, making it difficult for students to hide under the desks, and it is easy to cause panic when an earthquake occurs, and the ability to respond and judge is limited. And thus cause the anti-shock table to be unable to play a role at all, for this reason, we propose a kind of anti-seismic risk-avoiding safe use student desk
