Detailed description of the invention

In order to overcome the fixing seat that public arena provides, child and old man can not be facilitated to use, and there is the problem of the potential safety hazard fallen, present embodiments provide the liftable arm-chair shown in a kind of Fig. 1, comprise seat board 1, be arranged on the front table leg 2 of corner, seat board 1 bottom surface, 3, rear table leg 4, 5, be arranged on the backrest 6 of seat board 1 rearward end and be arranged on the handrail 12 of the seat board 1 end face left and right sides, 13, special feature is, described front table leg 2, 3, rear table leg 4, 5 are actively coupled with described seat board 1, make seat board 1 can around itself and front table leg 2, 3, rear table leg 4, the connection place of 5 is rotated, rear table leg 4,5 comprises outer tube and is set in the connecting rod in this outer tube, and is actively coupled by this connecting rod and described seat board 1, described connecting rod can pass in and out slip vertically in described outer tube,

Front table leg 2,3, rear table leg 4,5 is all arranged on carrier frame 7, and described front table leg 2,3 is fixed on carrier frame 7; Rear table leg 4,5 and this carrier frame 7 are actively coupled and can follow described seat board 1 around connection place and rotates, and make described connecting rod in the traction lower slider of this seat board 1; The inner side of the front bezel 8 of carrier frame 7 is fixedly connected with a holder 9, and this holder 9 is connected with the bottom surface of seat board 1 by the cylinder 10 of a Non-follow control, and described seat board 1 is rotated under the effect of this cylinder 10; The control valve operating lever 11 of cylinder 10 outwards also extends to described seat board 1 side obliquely from the bottom surface of described seat board 1; Backrest 6 is actively coupled by the rear end of rotating shaft and described handrail 12,13, rotates around junction when described seat board 1 rotates;

Described backrest 6 is connected by the rear frame 15 of telescoping support connecting rod 14 with described carrier frame 7, this telescoping support connecting rod 14 is fixedly connected with to guarantee that described backrest 6 can not tilt forward and back when seat board 1 rotates with described rear frame 15, namely in the process that seat board 1 rotates, along with the rotation of seat board 1, height converts backrest 6, stretch or compression telescoping support connecting rod 14, this telescoping support connecting rod 14 can be ordinary telescopic pipe, as long as its lower end and rear frame 15 are fixed, its upper end and backrest are fixed, when seat board 1 rotates, backrest 6 just drives telescoping support connecting rod 14 flexible along with up and down and under the effect of telescoping support connecting rod 14, keep backrest not rock on horizontal level.

Wherein, front table leg 2,3, rear table leg 4,5 all to be connected with seat board 1 by bearing pin or front table leg 2,3, rear table leg 4,5 all rivets with seat board 1 activity.

State backrest 6 to be connected with the bar hole be opened on handrail 12,13 by bearing pin, when described seat board 1 rotates, described bearing pin slides in described bar hole.

And the end face of seat board 1 arranges an arc groove 16, in order to contribute to human body attachment when seat board 1 tilts, prevent landing.

To sum up, be not difficult to find out, the liftable seat that the present embodiment provides, it is when nobody uses, namely original state is in the state shown in Fig. 2, namely under the effect of cylinder, seat board is upwards rotated, seat board is taken the form of inclined plane state, backrest then keeps and the state under the state shown in Fig. 1 under the effect of support link, when old man uses, first rely on the seat, then by control valve operating lever Non-follow control cylinder, make seat board cylinder pull and human bady gravitational or rely on power effect under slowly decline, until the state shown in Fig. 1, and when old man stands up, by control valve operating lever Non-follow control cylinder, seat board is upwards rotated forward under the jacking force effect of cylinder, play the effect of assisting old man in, very convenient, and effectively prevent the potential safety hazard easily fallen in the process of to sit down because of old man and standing up.
