Summary of the invention
The main purpose of the utility model provides a kind of simple in structure, can realize down the head upset couch frame of the back of the body and headrest upset simultaneously.
The utility model is provided with base, seat, back rest, headrest frame, headrest frame switching mechanism and electric pushrod;
Seat rear end and base upper end are rotationally connected, and back rest and base upper end are rotationally connected, and back rest lower end and electric pushrod front end are hinged; Headrest frame and back rest upper end are rotationally connected; Headrest frame switching mechanism is provided with headrest connecting rod, fixedly ear and gear bar, and the headrest small end is hinged with the headrest frame, the connecting rod lower end and fixedly the ear lower end is hinged of resting the head on; Fixedly ear is fixed on the base; Gear bar one end is fixed in the back rest lower end, and the gear bar other end is unsettled and in the face of being located at the gear face on the seat, electric pushrod is fixed on the base.
Said seat front end preferably is provided with little leg support, and little leg support is rotationally connected through little leg connecting rod and back rest lower end, and being rotationally connected is preferably hinged.
Said headrest frame can be provided with fixed head, returning face plate and pillow plate; Fixed head and back rest upper end are connected, and returning face plate one end and fixed head are hinged, and the returning face plate other end and said headrest small end are hinged.
The said gear bar other end preferably is provided with roller, and roller is convenient to contact rolling with said gear face and is cooperated.
Said back rest lower end and electric pushrod front end are hinged, and preferably the back rest lower end is provided with hinged ear, and hinged ear and electric pushrod front end are hinged.
On the said back rest massager core can be installed, the back rest that is provided with massager core can be used for massage armchair.
Compare with prior art, the utlity model has following outstanding advantage:
1, owing to be provided with headrest frame and headrest frame switching mechanism, therefore when electric pushrod was worked, electric pushrod drove back rest and rotates with respect to base; Because fixedly ear is motionless; Headrest connecting rod lower end is with fixedly the ear lower end is hinged, and the connecting rod of then resting the head on can be push-jump forward with the headrest frame, makes the pillow plate of the frame of resting the head on substantially parallel with back rest; Be equivalent to so extended in the back rest upper end, human body head is firmly rested the head on headrest.
2, because headrest frame switching mechanism is provided with the gear bar, and seat is provided with the gear face, gear bar one end is fixed in the back rest lower end; Therefore when back rest rotates; The gear bar can contact at the gear face, so just can seat be rotated lifting around base, thus zero-g function like can realizing intending.
3, owing to can be provided with little leg support, little leg support is hinged through little leg connecting rod and back rest lower end.When back rest rotates, can drive little leg connecting rod simultaneously and move like this, the shank connecting rod can drive little leg support and upwards rotate lifting, therefore can realize the shank stretching and pack up function.
This shows; The utility model only need adopt single push rod just can realize down the back of the body, headrest upset and shank Telescopic simultaneously; Have simple in structurely, easy to use and the outstanding advantage of the more grade of function can be widely used in lying fallow, on the chair of difference in functionalitys such as office, health care massage.
