Multifunctional desk integrating earthquake resistance and sitting posture correction

Abstract

The invention discloses a multifunctional desk integrating earthquake resistance and sitting posture correction. The desk comprises a supporting frame resistant to earthquakes, a desk box, a screw lifting mechanism and a double-layer desk plate provided with an adjustable buffering mechanism arranged in an interlayer, wherein the desk box is fixed to the upper end of the supporting frame resistant to earthquakes. The front side of the double-layer desk plate is hinged to the desk box in a movable mode through hinges, the screw lifting mechanism is vertically fixed to the rear side of the supporting frame resistant to earthquakes, the top end of the screw lifting mechanism is movably connected with the rear side of the double-layer desk plate and used for adjusting an inclined angle of the double-layer desk plate, and a regular triangle support is further vertically arranged on the rear side of the supporting frame resistant to earthquakes. The multifunctional desk integrating earthquake resistance and sitting posture correction can be transformed into an ordinary form, an anti-seismic form, a sitting posture correcting form, a drawing form and the like. Buffer and removal effects are achieved on heavy falling objects through the screw lifting mechanism and the like to protect personnel under the desk. The multifunctional desk integrating earthquake resistance and sitting posture correction is mainly applied to self-rescue of middle and primary schools dealing with emergency disasters such as earthquakes and daily study and life.

Description

technical field [0001] The invention relates to a multifunctional table, in particular to a multifunctional table which integrates anti-shock and correction of sitting posture. Background technique [0002] Earthquakes are one of the major natural disasters on Earth. Earthquakes occur every day on Earth, most of which are small in magnitude or occur in remote areas such as the ocean floor, where they are not felt by people. However, strong earthquakes in human activity areas often cause huge property losses and casualties. [0003] The seismic waves generated by earthquakes can directly cause damage or even collapse of buildings; damage the ground, produce ground cracks, subsidence, etc.; occur in mountainous areas and may cause landslides, avalanches, etc.; and strong earthquakes that occur on the seabed may cause tsunamis. Aftershocks can make the damage worse. The secondary disasters caused by the earthquake mainly include fires, floods and poisonous gas leakage caused...

AI Technical Summary

Problems solved by technology

[0006] 1. Poor adaptability, it can only simply provide a shelter for escapees, and has no other functions. When too many heavy objects fall, it cannot achieve the unloading function. It is a test for the carrying capacity of the table body

[0007] 2. The table body is heavy. In order to make the table withstand greater impact, designers often use a large-volume structure to withstand greater impact, but this will make the table heavy and unsuitable for school use.

[0008] 3. The cost is too high and it is not easy to popularize, because the existing anti-shock table mainly improves the anti-seismic performance from the material and structure, and some special anti-seismic and impact-resistant materials are often very expensive, so the cost of a single finished table is generally very high

[0009] 4. The function is single. The functions of the existing anti-shock desks are only anti-seismic and learning, and no consideration is given to linking the anti-seismic function with other functions through a certain mechanism to realize the multi-functionality of the desk.
