Abstract
The invention discloses a mechanical lift type seating device which comprises a base and a seat. A rod sleeve and a gear carrier are arranged on the base, a rack rod is arranged in the rod sleeve, racks are arranged on the rack rod, the top of the rack rod is connected with the seat, a gear is arranged on the gear carrier, gear teeth on the gear are connected with the racks arranged on the rack rod, an axle of the gear is connected with a handle, and seating persons can turn the handle to rotate according to height requirements, so that the height of the rack rod can be adjusted, and the mechanical lift type seating device which is a chair can move in an ascending or descending manner. The mechanical lift type seating device has the advantages that the mechanical lift type seating device is simple and compact in structure, convenient to operate and high in reliability and can bring great convenience for the seating persons, and the confinement that the heights of the traditional chairs cannot be adjusted can be broken through.
Description
Technical field
A kind of mechanical lifting thing to sit on of the present invention, belongs to chair lift renovation technique field.
Background technology
At present; along with developing rapidly of social progress and catering trade; the chair that a lot of dining room or family oneself use; highly nearly all can not regulate; therefore the height of no matter people; especially child and old man; all must adapt to the chair of same level altitude; a lot of inconvenience is brought to taking a seat; and existing adjustable chair lift is all regulated by cylinder, but the existing chair lift security being undertaken regulating by cylinder can not be guaranteed, the accident that often can meet accident; user is damaged, so existing chair lift Shortcomings.
Summary of the invention
The object of the invention is: provide that a kind of structure is simple, easy and simple to handle, compact conformation, just can be realized a kind of mechanical lifting thing to sit on of chair height lifting by simple operations, to overcome the deficiencies in the prior art.
The present invention is achieved in that a kind of mechanical lifting thing to sit on, comprise base and seat support, base is provided with bar cover and tooth rest, rack bar is provided with in bar cover, rack bar is provided with tooth bar, and the top of rack bar is connected with seat support, and tooth rest is provided with gear, the gear teeth on gear are connected with the tooth bar that rack bar is arranged, and the wheel shaft of gear is connected with handle.
Bar cover is provided with the opening that wheel and rack can be allowed to be connected.
The top of rack bar is turbination.
Rack bar is arranged with 8 ~ 12 tooth bars from equidistant under upper.
Tooth rest is provided with the latch preventing pinion rotation.
Owing to have employed technique scheme, occupant can according to the height needs of oneself, rotated by turning handle and carry out rack bar Height Adjustment, realize the rising of chair or decline mobile, because its structure is simple, easy to operate, reliability is high, compact conformation, brings larger convenience to occupant, has broken the confinement that conventional chair can not carry out highly regulating.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail, but not as limitation of the present invention.
Embodiments of the invention: a kind of mechanical lifting thing to sit on, comprise base 1 and seat support 2, base 1 is provided with bar cover 3 and tooth rest 4, rack bar 5 is provided with in bar cover 3, rack bar 5 is provided with tooth bar 6, and the top of rack bar 5 is connected with seat support 2, and tooth rest 4 is provided with gear 7, the gear teeth on gear 7 are connected with the tooth bar 6 that rack bar 5 is arranged, and the wheel shaft of gear 7 is connected with handle 8.，
Bar cover 3 is provided with the opening 9 that gear 7 can be allowed to be connected with tooth bar 6.
The top of rack bar 5 is turbination.
Rack bar 5 is arranged with 8 ~ 12 tooth bars 6 from equidistant under upper.
Tooth rest 4 is provided with the latch 10 preventing gear 7 from rotating.
Rack bar 5 is a cylindrical bar, and top is turbination, is fixedly connected with seat support 2, ensures that the contact area of rack bar 5 and seat support 2 is comparatively large, ensures chair security; The trunk portion of rack bar 5 is designed with tooth bar 6, and tooth bar 6 can reasonable coordination with the gear teeth on gear 5.
The internal diameter of bar cover 3 is greater than the trunk external diameter of rack bar 5, and ensure that rack bar 5 can move up and down unobstructed, bar overlaps 3 sides and offers opening 9, facilitates rack bar 5 directly can contact cooperation with gear 7.
In tooth rest 4, be provided with gear 7, the gear teeth of gear 7 can coordinate with the tooth bar 6 on rack bar 5, ensure that gear 7 can drive rack bar 5 to move up and down.
Bar cover 3 be hollow component, and bottom be conical, and larger contact area is arranged at installation rack bars 5 in bar cover 3 and bottom relatively mask, and guarantee chair can steadily be laid.
One end of gear 7 is provided with handle 8, and handle 8 is fixedly connected with the wheel shaft of gear 7, can the rotation of driven gear 7 by turning handle 8.
One end of tooth rest 4 mounting handle 8 is provided with latch 10, and latch 10 can be braked gear, is convenient to after chair height regulates, and by fixing for gear with fixing chair height, prevents chair to be again subjected to displacement.
Manually rotary handle 8 carries out clockwise or is rotated counterclockwise, and drives rack bar 5 motion to realize chair and moves up and down, thus realize the adjustable of chair height; By the braking action of latch 10, chair height can be fixed.
Owing to have employed technique scheme, occupant according to the height needs of oneself, can be rotated by turning handle and carries out rack bar Height Adjustment, realizes the rising of chair or declines mobile.Because its structure is simple, easy to operate, reliability is high, compact conformation, brings larger convenience to occupant, has broken the confinement that conventional chair can not carry out highly regulating.
