Abstract
The utility model discloses an actuator linkage of dental chair. The utility model is provided with a movable side board between a bearing side board and a chair seat, one end of the bearing side board which near a chair back is connected with one end of the movable side board through a rotable pivot point, the other end of the movable side board is connected with the chair back through the pivot point of a chair seat connection frame; one side of the movable side board which is far from the chair back is fixedly equipped with the rotable pivot point, the rotable pivot point is connected with one end of a movable supporting rod, the other end of the movable supporting rod is connected with the other end of the bearing side board through the rotable pivot point; one end of the chair back which is far from the chair back is bended upward to form a drive frame, and the upper end of the drive frame is connected with the rotable pivot point which is arranged at one side of the movable side board that is far from the chair back. The utility model has simple structure, easy processing, low cost and failure rate; furthermore, the utility model can change the degrees of tilt of the chair seat only by changing the position of the rotable pivot point which is arranged at one side of the movable side board, which has very easy use and broad scope of application.
Description
Technical field
This utility model relates to a kind of interlock actuating device of dental chair, relates in particular between a kind of seat support that can make dental chair and the chair back actuating device of interlock automatically, belongs to the dental instruments production field.
Background technology
Dental chair is as the part of dental therapeutic tool, play an important role the same with the dental treatment instrument, owing in therapeutic process, need the patient to change the position of head, and the head that needs the patient leans against on the headrest of the chair back to keep stable for a long time, so present dental chair generally all adopts motor (or hydraulic pressure) to promote the angle of chair back connecting rod with the change chair back, thereby change the position of patient's head.For the patient feels comfortable, when changing chair back angle, need suitably to adjust the gradient of seat support, so at seat support, between chair back connecting rod and the bearing strut corresponding actuating device is installed, in the existing dental chair, this actuating device adopts a movable brace rod is installed between seat support link fulcrum and bearing strut fulcrum, the mode of between seat support link fulcrum and the chair back connecting rod fulcrum movable brace rod being installed realizes, the shortcoming of this device is: because the bearing strut bears big pressure, need just can guarantee safety than the crude steel material, so a waste material is arranged, strengthened cost; And since between seat support link fulcrum and the chair back connecting rod fulcrum distance determine that the size of malleable seat support gradient not is so the scope of application is less, transmutability is relatively poor.
Summary of the invention
The purpose of this utility model provides a kind of interlock actuating device that can make the dental chair that reaches better interlock effect 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:
This utility model is installed between seat support, chair back connecting rod and the bearing side plate, movable side plate is installed between bearing side plate and seat support, end near the chair back on the bearing side plate is connected by rotatable fulcrum with an end of movable side plate, and the other end of movable side plate is connected by seat support link fulcrum with seat support; Side away from the chair back on movable side plate is installed with rotatable fulcrum, and this rotatable fulcrum is connected with an end of movable brace rod, and the other end of movable brace rod is connected by rotatable fulcrum with the other end of bearing side plate; Chair back connecting rod is bent upwards the formation gear frame away from an end of the chair back, the upper end of gear frame be installed on movable side plate on be connected away from the rotatable fulcrum of a side of the chair back.
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 gear frame, gear frame drives chair back connecting rod, chair back connecting rod drives the chair back and raises, simultaneously, chair back connecting rod drives movable brace rod and movable side plate moves to the direction of the chair back, this will inevitably make the distance between seat support link fulcrum and the bearing side plate diminish, because the bearing side plate is fixed, so seat support link fulcrum can move down, and seat support link fulcrum is fixed on close chair back one side on the seat support, so the gradient of seat support can become greatly, promptly realizes automatic angle compensation between the seat support and the chair back, 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:
Because the required material of movable side plate and movable brace rod is few, and the bearing side plate is just to have originally, so this utility model is simple in structure, with low cost and easy processing, fault rate are low, and it is because only need the position of the rotatable fulcrum of change activity side plate one side can change the size of seat support gradient, so very convenient and the scope of application is extensive.
Description of drawings
Fig. 1 is a side-looking structural representation of the present utility model;
Fig. 2 is the enlarged drawing of A among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described in detail:
As depicted in figs. 1 and 2, this utility model is installed between seat support 7, chair back connecting rod 2 and the bearing side plate 12, movable side plate 3 is installed between bearing side plate 12 and seat support 7, end near the chair back 1 on the bearing side plate 12 is connected by rotatable fulcrum 11 with an end of movable side plate 3, and the other end of movable side plate 3 is connected by seat support link fulcrum 4 with seat support 7; Side away from the chair back 1 on movable side plate 3 is installed with rotatable fulcrum 5, and rotatable fulcrum 5 is connected with an end of movable brace rod 9, and the other end of movable brace rod 9 is connected by rotatable fulcrum 6 with the other end of bearing side plate 12; Chair back connecting rod 2 is bent upwards formation gear frame 10 away from an end of the chair back 1, and the upper end of gear frame 10 is connected with rotatable fulcrum 5.
As depicted in figs. 1 and 2, in transmission process, to raise the vertical angle that the chair back 1 promptly reduces the chair back 1 is example, the drive link that at first is motor 8 promotes gear frame 10, gear frame 10 drives chair back connecting rod 2, chair back connecting rod 2 drives the chair back 1 and raises, simultaneously, chair back connecting rod 2 drives movable brace rod 9 and movable side plate 3 moves to the direction of the chair back 1, this will inevitably make the distance between seat support link fulcrum 4 and the bearing side plate 12 diminish, because bearing side plate 12 is fixed, so seat support link fulcrum 4 can move down, and seat support link fulcrum 4 is what to be fixed on the seat support 7 near one side of the chair back 1, so it is big that the gradient of seat support 7 can become, promptly between the seat support 7 and the chair back 1, realize automatic angle compensation, meet the natural angle of human body, make human body sensory more comfortable.Otherwise if will reduce the level angle that the chair back 1 promptly reduces the chair back 1, then whole process is with last opposite, and the gradient of final seat support 7 can diminish the more approaching purpose that lies low.
