Big space, makes the lower adjusted position of medicated cushion be restricted, brings inconvenience to the operation of patient and doctor, the most special need
Wanting crowd, such as child's and people with disability is medical the most particularly inconvenient, additionally, the position of back of seat mostly is in seat lifting at present
After completing, then adjust by hand, operation more bothers.
Utility model content
The purpose of this utility model is to provide a kind of seat cushion linkage structure for tooth machine, to solve above-mentioned background technology
The problem of middle proposition.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of seat cushion linkage structure for tooth machine, including sliding chute seat, the surface of described sliding chute seat is provided with chute hole, and sliding
Slotted eye connects has the roller mount corresponding with chute hole, the bottom of described sliding chute seat to be provided with back bracket, and sliding chute seat is by rolling
Wheel seat is slidably connected with back bracket, and the bottom of described sliding chute seat connects has linkage rotating shaft, described linkage rotating shaft to be located at linkage base
On seat, described linkage pedestal is provided with seat frame away from one end of linkage rotating shaft, and described linkage pedestal is connected by rocker pivot axis
In linkage pole, described linkage pedestal is positioned at the lower section of sliding chute seat, and sliding chute seat is connected to the rocking bar that links, institute by linkage pole
The other end connection stating linkage rocking bar has linkage push rod, described linkage push rod to be connected to the top of roller mount.
Preferably, the bottom of described linkage pedestal is provided with base.
Preferably, driving motor it is provided with between described sliding chute seat and roller mount.
Preferably, the chute hole on described sliding chute seat is arc shape.
Compared with prior art, the beneficial effects of the utility model are: this is used for the seat cushion linkage structure of tooth machine by driving
Dynamic driven by motor roller mount is slided around sliding chute seat, it is possible to drives linkage push rod, linkage rocking bar and linkage pole to move successively, makes
Obtain the continuous raising and lowering of back bracket of tooth machine chair, it is possible to constantly regulate according to the demand of people, time saving and energy saving, the most just
Just, it is not required that take bigger space, and by regulating the relative dimensions of each gangbar, regulation rotates initial point and gangbar
Between size relationship can be movable to required rotational angle and offset angle very easily.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is that this utility model uses view.
In figure: 1 linkage rotating shaft, 2 linkage push rods, 3 linkage rocking bars, 4 linkage poles, 5 linkage pedestals, 6 back bracket, 7 sliding
Groove seat, 8 roller mount, 9 medicated cushion framves.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Fig. 1-2, a kind of technical scheme of this utility model offer: a kind of seat cushion linkage structure for tooth machine, bag are provided
Including sliding chute seat 7, the surface of sliding chute seat 7 is provided with chute hole, and chute hole connection has the roller mount 8 corresponding with chute hole, chute
The bottom of seat 7 is provided with back bracket 6, and sliding chute seat 7 is slidably connected with back bracket 6 by roller mount 8, the bottom of sliding chute seat 7
Connecting and have linkage rotating shaft 1, linkage rotating shaft 1 is located on linkage pedestal 5, and linkage pedestal 5 is provided with seat cushion away from one end of linkage rotating shaft 1
Frame 9, linkage pedestal 5 is connected to, by rocker pivot axis, pole 4 of linking, and linkage pedestal 5 is positioned at the lower section of sliding chute seat 7, and chute
Seat 7 is connected to, by linkage pole 4, the rocking bar 3 that links, and the other end of linkage rocking bar 3 connects linkage push rod 2, and linkage push rod 2 is even
It is connected to the top of roller mount 8.The bottom of linkage pedestal 5 is provided with base, is provided with driving motor between sliding chute seat 7 and roller mount 8, sliding
Chute hole in groove seat 7 is arc shape.
The seat cushion linkage structure of this tooth machine is slided around sliding chute seat 7 by driving driven by motor roller mount 8, it is possible to carry successively
Dynamic linkage push rod 2, linkage rocking bar 3 and linkage pole 4 are moved so that the continuous raising and lowering of back bracket 6 of tooth machine chair, energy
Enough constantly regulate according to the demand of people, time saving and energy saving, simple and convenient.
In use, when driving motor to realize projecting motion, roller mount 8 is counterclockwise around sliding chute seat 7 for this utility model
Sliding, drive linkage push rod 2 to push away forward, linkage push rod 2 drives linkage rocking bar 3 to turn counterclockwise around linkage pedestal 5 rocker pivot axis
Dynamic, thus drive linkage pole 4 counter-clockwise swing, linkage pole 4 drives sliding chute seat 7 to rotate counterclockwise, finally around linkage rotating shaft 1
