Summary of the invention
The purpose of this utility model provides a kind of actuator linkage of realizing the treatment chair of interlock easily between the seat support and the chair back with regard to being to address the above problem.
In order to achieve the above object, this utility model is realized in the following manner:
In this utility model, between seat support, chair back connecting rod and bearing strut, the movable brace rod that two ends all adopt the mode of rotatable flexible connection to connect is installed, when changing chair back angle, to change the gradient of seat support, reach the seat support and the chair back purpose of interlock automatically, it is characterized in that being equipped with between seat support, chair back connecting rod and bearing strut the movable brace rod more than three or three, the mode by the rotatable flexible connection of head and the tail between the piecemeal activity strut connects separately.
In these movable brace rods that connect separately by modes of the rotatable flexible connection of head and the tail owing to there is not fixed pivot, so its rotatable connection fulcrum can in transmission process, move, thereby in transmission process, played steady over-drastic effect.
As best mode of the present utility model, three movable brace rods are installed between seat support, chair back connecting rod and bearing strut, the fulcrum of chair back connecting rod is connected with an end of article one movable brace rod, the other end of this movable brace rod is connected by fulcrum with an end of second movable brace rod, the other end of second movable brace rod is connected with seat support link fulcrum, part between the two ends of second movable brace rod is provided with fulcrum, this fulcrum is connected with an end of the 3rd movable brace rod, and the other end of the 3rd movable brace rod is connected with the fulcrum of bearing strut.
Said structure is in transmission process, to raise the vertical angle that the chair back promptly reduces the chair back is example, the drive link that at first is motor (or hydraulic means) promotes chair back connecting rod, at this moment chair back connecting rod can rotate under the control of bearing fulcrum, thereby driving the chair back raises, simultaneously, chair back connecting rod drives three movable brace rods and all moves to the direction of the chair back, this will inevitably make the distance between seat support link fulcrum and the bearing strut fulcrum diminish, because bearing strut fulcrum is a fixing point, so seat support link fulcrum can move down, the close chair back so the gradient of seat support can become greatly, has promptly compensated respective angles on one side automatically on the seat support between the seat support and the chair back and seat support link fulcrum is fixed on, meet the natural angle of human body, make human body sensory more comfortable.Otherwise if will reduce the level angle that the chair back promptly reduces the chair back, then whole process is with last opposite, and the gradient of final seat support can diminish the more approaching purpose that lies low.
The beneficial effects of the utility model are: as from the foregoing, transmission process of the present utility model is stable, at the uniform velocity, human body sensory is comfortable, and can reach treatment chair that adapts to different size and the purpose that changes the gradient size of seat support by the length of adjustment movable brace rod and the position of fulcrum, so the scope of application is extensive, transmutability is strong.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described in detail:
As shown in drawings, at seat support 4, it is movable brace rod 9 that the movable brace rod that all adopts the mode of rotatable flexible connection to connect in three two ends is installed between the strut 15 of chair back connecting rod 11 and bearing 10, movable brace rod 8 and movable brace rod 12, the fulcrum 13 of chair back connecting rod 11 is connected with an end of movable brace rod 9, the other end of movable brace rod 9 is connected by fulcrum 7 with an end of movable brace rod 8, the other end of movable brace rod 8 is connected with seat support link fulcrum 3, part between the two ends of movable brace rod 8 is provided with fulcrum 2, fulcrum 2 is connected with an end of movable brace rod 12, and the other end of movable brace rod 12 is connected with the fulcrum 6 of bearing strut 15.
