Abstract
The invention discloses an elastic-pin braking lifting-type seating device. The seating device comprises a seat composed of a backrest, handrails and a chair seat and a base, wherein a column sleeve is arranged on the base, a braking frame is arranged on the column sleeve, an inverted tooth column is arranged inside the column sleeve, inverted teeth are arranged on the inverted tooth column, a braking pin is arranged inside the braking frame, and one end of the braking pin is inserted into a gap between the inverted teeth. A seating person can manually operate the chair and a pull ring to make the chair ascend or descend according to own height requirements. Because the seating device is simple in structure, convenient to operate, high in reliability and compact in structure, great convenience is brought to the seating person, and the defect that the height of a traditional chair can not be adjusted is overcome.
Description
Technical field
A kind of bullet pin braking lift thing to sit on of the present invention, particularly a kind of bullet pin braking chair lift, 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 bullet pin braking lift 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 bullet pin braking lift thing to sit on, comprise the seat and base that are made up of backrest, handrail and seat support, base is provided with column sleeve, column sleeve is provided with damper frame, pawl post is provided with in column sleeve, pawl post is provided with pawl, in damper frame, is provided with banking pin, one end of banking pin is inserted in the slot of pawl.
Banking pin is provided with spacing ring, between spacing ring and damper frame inside casing wall, is provided with spring, one end of banking pin is provided with draw ring.
Banking pin is closed by screw and dome and is fixed in damper frame.
Pawl column top is back taper.
Pawl post from be arranged with 10 ~ 30 pawls, form teeth groove between two often adjacent pawls.
Owing to have employed technique scheme, occupant can according to the height needs of oneself, and manually operation of chair and draw ring 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 bullet pin braking lift thing to sit on, comprise the seat and base 14 that are made up of backrest 1, handrail 2 and seat support 3, base 14 is provided with column sleeve 5, column sleeve 5 is provided with damper frame 7, pawl post 4 is provided with in column sleeve 5, pawl post 4 is provided with pawl 6, is provided with banking pin 8 in damper frame 7, one end of banking pin 8 is inserted in the slot of pawl 6.
Banking pin 8 is provided with spacing ring 12, between spacing ring 12 and damper frame 7 inside casing wall, is provided with spring 13, one end of banking pin 8 is provided with draw ring 10.
Banking pin 8 is closed by screw 11 and dome 9 and is fixed in damper frame 7.
Pawl post 4 top is back taper.
Pawl post 4 from be arranged with 10 ~ 30 pawls 6, form teeth groove between two often adjacent pawls 6.
Pawl post 4 is a cylindrical bar, and primary stem portion is provided with pawl 6, and top is back taper, ensures that the contact area of seat support 3 and pawl post 4 is larger.
Column sleeve 5 is hollow part, and its internal diameter is greater than the maximum outside diameter of pawl post 4 trunk portion, ensures that pawl post 4 can move up and down unobstructed; Column sleeve 5 side is designed with the aperture facilitating banking pin 8 to work, and bottom it, external diameter is comparatively large, ensures that chair can steadily be laid.
Be provided with damper frame 7 in the side of column sleeve 5, damper frame 7 inside is provided with banking pin 8 and spring 13, and is undertaken closed fixing by screw 11 dome 9.
Banking pin 8 is provided with spacing ring 12 and draw ring 10, spring 13 by withstanding spacing ring 12, thus realizes effect banking pin 8 being applied to elastic force; When chair height needs to reduce, draw ring 10 is pulled outwardly, banking pin 8 to outer displacement, the braking action of brake off pin 8 pairs of pawl posts 4, thus pawl post 4 can be moved down.
Owing to have employed technique scheme, occupant can according to the height needs of oneself, and manually operation of chair and draw ring 10 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 eater, has broken the confinement that conventional chair can not carry out highly regulating.
