The advantage that this utility model is compared with prior art had is: simple in structure, volume is little, and is cheap for manufacturing cost, and it is reliable to operate steadily, and torsion spring has more safety as the elastic force-applying element, can not push the problem of human body or equipment damage.This utility model is in the folding movement of the elevating movement of dental chair backrest and seat cushion; Utilize the push-and-pull campaign of dental chair backrest drive motors in elevating movement; Make the sole of putting of seat cushion front end produce synchronous interaction through the torsion of torsion spring and the transmission of backguy, realize flexible automatically.Adopt the backguy principle, the complex spatial transmission is converted into simple stretching transmission.Utilize torsion spring as thrust component, reduce structure space, more enlarged patient's the space of taking.
Four, description of drawings
Accompanying drawing is this utility model overall structure sketch map.
Five, the specific embodiment
Combine accompanying drawing this utility model to be explained further details with specific embodiments at present:
A kind of dental chair seat cushion is folding and put the sole automatic extending-contracting apparatus, and it is made up of base and support, on support, is provided with seat cushion.Be fixed with connecting plate 11 on the base 12, back cushion rack 10 is fixedly connected with base 12 through connecting plate 11, is fixed with back seat cushion (not shown in FIG.) above the back cushion rack 10; Be fixed with back connecting plate 8 on the back cushion rack 10, preceding cushion rack 6 is connected seat cushion 3 before being fixed with on the preceding cushion rack 6 through rotating shaft 7 with back connecting plate 8; Put sole support 2 and be fixedly connected with preceding cushion rack 6, put sole 1 through slide rail 24 with put sole support 2 and be slidingly connected, torsion spring 4 one ends are connected through torsion spring post 23 and put on the sole support 2; The other end is connected and puts on the sole 1 through putting on the sole 1 second torsion spring post, and guide pad 5 is fixedly connected with preceding cushion rack 6, and electric machine support 21 is fixedly connected with connecting plate 11; Linear electric motors 9 one ends are connected with electric machine support 21; One end is connected with backrest connector 18, on base 12, is provided with arc chute, and chute is provided with carriage; Described carriage is in chute, to be provided with slide block 16; Slide block connector 17 is fixedly connected with slide block 16, and connecting rod 13 1 ends are connected on the slide block connector 17, and an end and guide pad 5 are slidingly connected; Connecting rod is provided with connecting rod directive wheel 20 and connecting rod spacer pin 19 in both sides about in the of 13, and backguy 14 1 ends utilize backguy hold-down screw 15 to be fixed on the connecting rod 13, and an end is fixed in to be put on the sole 1.On base 12, be provided with electronic push-pull device at fixed, described electronic push-pull device at fixed is on base 12, to be fixed with linear electric motors 9, and the other end of linear electric motors 9 is connected with backrest connector 18; Linear electric motors 9 promote backrest connector 18 and in arc chute, move when original state is done stretching motion, and backrest connector 18 drives slide blocks 16 and moves together with slide block connector 17 and drivening rod 13; Because the effect of connecting rod directive wheel 20 and connecting rod spacer pin 19, connecting rod 13 can only be pressed the desired trajectory motion, connecting rod 13 1 ends move on guide pad 5; The jackknife action of seat cushion 3 before accomplishing, simultaneously, because the motion of connecting rod 13; Drive backguy 14, backguy 14 drives again puts sole 1 and does contractile motion; On the contrary, when linear electric motors 9 were done contractile motion, pulling backrest connector 18 moved in arc chute; Backrest connector 18 drives slide block 16 and moves together with slide block connector 17 and drivening rod 13, and seat cushion 3 is done stretching before driving, simultaneously; Because the motion of connecting rod 13; Discharge backguy 14, at this moment, put sole 1 and under the thrust of torsion spring 4, do stretching motion.
On base 12, be provided with arc chute, the slide block 16 that is provided with that in arc chute, slides connects into an integral body with slide block connector 17; Connecting rod 13 1 ends and guide pad 5 are slidingly connected, and the other end is connected with slide block connector 17, during linear electric motors 9 motions, drive preceding seat cushion 3 through slide block connector 17 and fold; Simultaneously, the complex spatial transmission is converted into simple stretching transmission, drives and put sole 1 contraction through backguy 14 putting sole 1 and being provided with backguy 14 between the fixed guy wire support 22 and connecting rod 13 through putting on the sole support 2; Torsion spring 4 is installed putting sole 1 and put between the sole support 2, the effect of torsion spring 4 is in the lax process of backguy 14, promotes to put sole 1 and stretches out, and realizes putting the automatic Telescopic of sole 1.
When dental chair was positioned at the initial position state, stretched out for the longest the motion end of linear electric motors 9, and backrest connector 18 is in the position of bowing most, and preceding seat cushion 3 is turned up, and puts sole 1 and be pulled to complete contraction state by backguy 14.
Need backrest connector 18 to face upward following time, linear electric motors 9 tache motorices shrink gradually and shorten, and pulling backrest connector 18 is faced upward downwards, and drives slide block 16 in the cambered way slides forwards, and connecting rod 13 travels forward, with preceding seat cushion 3 jack-up, and the stretching of seat cushion 3 before realizing.
Simultaneously,, make backguy 14 loosen gradually, put sole 1 and under the thrust of torsion spring 4, stretch out gradually because connecting rod 13 travels forward, the synchronous interaction that sole is put in realization, flexible automatically.
Vice versa.
