Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.

nullRefer to Fig. 1，This utility model provides a kind of technical scheme: a kind of student uses anti-down tablet chair，Including seat 1，The side of seat 1 connects the chair back 101，The one side of seat 1 is provided with controller 16，The back side of the chair back 101 is sequentially provided with two fixing seats 11 and two soft sheaths 14 from top to bottom，The side of fixing seat 11 is provided with baffle plate，The width of baffle plate is the half of fixing seat 11 one side width，The central shaft of fixing seat 11 offers hole slot，Connect in hole slot and have bolt，Make structure more firm，When pillar 12 is softened，Support is to maximum angle，Baffle plate can block the slip of pillar 12，Make to support stronger，Pillar 12 all it is hinged with on two fixing seats 11，The end of pillar 12 is provided with Anti-slip cover，When pillar 12 is softened and contacts ground，The power of moment is overweight，It is prone to partially slide，Anti-slip cover is possible to prevent pillar 12 the most sliding，It is connected by back-moving spring 13 between pillar 12 with the chair back 101，And the end of pillar 12 is interspersed in soft sheath 14，The bottom of seat 1 is provided with four supporting legs 2，Connect between the supporting leg 2 of two, the same side and have crossbeam 3，The side of crossbeam 3 is provided with glove room 4，The side of the intracavity bottom of glove room 4 is provided with pressure transducer 5，The side inwall of glove room 4 is provided with driving motor 6，The output shaft driving motor 6 connects the first rotating disk 7，And the middle part of the supporting leg 2 adjacent with glove room 4 is connected by rotating shaft the second rotating disk 8，The surface of the second rotating disk 8 is provided with guard shield，Guard shield is connected on supporting leg 2 by screw，Guard shield is steel，In order to avoid tablet chair falls down to the ground breaks the second rotating disk 8，It is connected by the first cable wire 9 between first rotating disk 7 and the second rotating disk 8，Top, glove room 4 is interted the surface of hole of cable wire and is provided with dust ring，In order to avoid dust enters glove room 4，The entrance preventing dust can protect assembly normally to work，And second the top of one side of rotating disk 8 be provided with wire clamp 10，And connected by the second cable wire 15 between wire clamp 10 and soft sheath 14，Controller 16 is electrically connected with pressure transducer 5 and drives motor 6.
