Apart from larger, backrest has the feeling of chopping when rotating, and when 2. backrests rotate, the mounting plate on seat cushion can do front and back compensation fortune
It is dynamic, it drives seat cushion with respect to human motion, the patient feels can be made to be pullled, in patient's treatment, other bodies can be brought to patient
On discomfort, treat patient from feeling at ease, influence therapeutic effect, to sum up the problem of, it is desirable to provide one kind can make backrest and seat
A kind of uncomfortable connection structure will not be brought to human body when pad rotation.
[summary of the invention]
The purpose of the present invention is to provide a kind of comfort height, chopping sense is small and can play rotation benefit during rotation
Repay the connection structure of effect.
To achieve the above object, a kind of connection structure for dentistry chair back of the invention, including it is seat support plate, solid
One end of fixed board, backrest and compensation mechanism, wherein one end of the fixed plate and the seat support plate is rotatablely connected, the other end
It is connected by compensation mechanism and the other end of fixed plate, the compensation mechanism includes rotating bar, the first pull rod, the second pull rod and the
Three pull rods, the rotating bar both ends are equipped with connecting rod, and the seat support plate is equipped with the mounting portion to raise upward, the rotation
Bar is rotatablely connected by connecting rod and mounting portion, and the backrest is fixed in rotating bar, and one end of first pull rod, which rotates, to be connected
It connects in connecting rod, the other end is connect with one end of the second pull rod, and the other end of second pull rod is rotatably connected on seat cushion branch
On fagging, one end of the third pull rod and the second pull rod are rotatablely connected, and the other end is rotatably connected in fixed plate.
Further, crossbeam is additionally provided on the seat support plate, the both ends of the crossbeam are separately fixed at two block pads
In support plate.
Further, the backrest includes curved portion and flat part, and one end of the arc panel is fixed in rotating bar, separately
One end is fixedly connected with flat part.
Further, the crossbeam is equipped with several mounting holes, and the mounting hole is located at seat support plate for fixed
The seat cushion of side.
Contribution of the invention is to provide a kind of connection structure for dentistry chair back, above present advance expenditure fagging
Mounting portion and rotating bar be rotatablely connected, backrest is fixed in rotating bar, and conventional rotary is compared in the position of connection structure rotation point
Point increases the rotation point of backrest for being located at below seat support plate, shorten rotation point and human body waist rotation away from
From to reduce chopping sense, when in addition backrest rotates, seat support plate does compensation campaign by compensation mechanism, and backrest increases, peace
Loading board rotates down, increases the angle of mounting plate and backrest, and constriction when smaller patient is pushed away by back is slept above more
Comfortably, it will not generate uncomfortable, can feel at ease to treat.
[Detailed description of the invention]
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is partial structural diagram of the present invention.
Fig. 3 is another partial structural diagram of the present invention.
