During use, need human body to be close to and lean against, just can make the backguy axle be in tension, just can make securing rod support the desktop treadmill, could normally learn.Otherwise in case bow-backed, lean against and do not stress, the backguy axle is in relaxed state so, and then securing rod is regained under the effect of returning pull-spring, and then treadmill loses to support to turn over and falls, and just can not work.This structure can make the people keep back straight, and has controlled the distance of eyes and desktop, just plays the effect of vision protection.So this tables and chairs are to have played real health-care effect really.
Be illustrated below in conjunction with drawings and Examples:
Fig. 1 is a general structure schematic diagram of the present utility model;
Fig. 2 is the utility model control treadmill upset operation principle structural representation.
As shown in Figures 1 and 2, the utility model is made up of table 1 and chair 2.Desk is made table leg 4 by height-adjustable multistage latch 3 structures, and its rectangle desktop 5 is made of frame 6 and intermediate active flat board 7, and treadmill is provided with a transverse axis 8 by the bottom, and the two ends of axle 8 are fixed on the bottom of frame both sides, and is dull and stereotyped turning.Chair is made chair leg 10 by height-adjustable multistage latch 9 structures, seat 11 bottoms are provided with transverse axis 12, be fixed on two side skeletons 13 of the back of the body, leaning against 14 two side skeletons 15 is movably connected on the axle 12, can rotate around 12, lean against 14 horizontal skeleton 15 by rotate thereupon, laterally skeleton 15 is to adopt multistage latch 21 to make Height Adjustable structure.Table frame is provided with a securing rod 16 and is used for supporting treadmill, and securing rod can rotate around a free bearing 17 (being fixed on the frame), and securing rod one end links to each other with a backguy axle A, and the returning pull-spring 18 that the other end and is fixed on the frame links to each other.When the backguy axle was strained, the pulling force that securing rod overcomes returning pull-spring was in the state of stretching out, and can support treadmill, if the backguy axle is loose, securing rod is regained under the effect of returning pull-spring, and treadmill will lose to support to turn over and fall.And the other end of backguy axle is connecting on the horizontal skeleton 15 in the skeleton that leans against. rotate along with leaning against skeleton, laterally skeleton 15 upwards changes, with backguy axle tension, then securing rod stretches out treadmill is supported, and leans against and will guarantee that horizontal skeleton upwards changes must the health seat just be close to.One leaves and leans against, and laterally skeleton falls, and backguy axle limit is loose, and then securing rod is regained under the returning pull-spring effect, and treadmill turns over, and plays the warning effect.So the utility model can guarantee that really sitting posture is correct, vision protection.Because the leg of chair and lean against and can both regulate height is so can be suitable for various human body height needs.The backguy axle is made of sheath 19 and inner steel wire 20, adopts the bicycle brake axle.
