Abstract
The utility model relates to a lifting/lowering device, especially to a headrest lifting/lowering device widely used in massage armchairs, lounges, leisure beds, electric elevator chairs, electric elevator beds. The headrest lifting/lowering device comprises an outline border, an underframe fixed at the bottom of the outline border, a elevator upperframe parallel to the underframe, a pair of coplanar sliding chutes symmetrically arranged on the underframe and the upperframe respectively, an elevator rack arranged between the underframe and the upperframe, a plastic wheel which is arranged at the top of the elevator rack and is inserted into said sliding chutes, an electric push rod which is arranged at the bottom of said elevator rack and is used for pushing said elevator rack. The utility model features that the angle between two supporting rods of the elevator rack pushed by the electric push rod controlled by a circuit board changes and the upperframe rises or falls with the plastic wheel to implement the independent adjustment of head height, and that the lift height is controllable by a displacement sensor, and that a stable lift can be obtained with an L-shaped component.
Description
Technical field
The utility model relates to lowering or hoisting gear, is specifically related to a kind of massage armchair, leisure chaise longue, leisure bed, electric up-down chair, occipitalia lowering or hoisting gear on electric up-down bed of can be widely used in.
Background technology
In the prior art, massage armchair, leisure chaise longue, leisure bed, electric up-down chair, all there is not the occipitalia lowering or hoisting gear that is provided with separately on electric up-down bed, usually all be to rely on the angle of regulating backrest to regulate the height of head of a bed head, use inconvenience, can not realize regulating separately the high low-function of head.
The utility model content
The purpose of this utility model is to provide a kind of massage armchair, leisure chaise longue, leisure bed, electric up-down chair, occipitalia lowering or hoisting gear on electric up-down bed of being used for.When needed, can regulate the height of head separately.
The technical scheme that the utility model provides is as follows: construct a kind of occipitalia lowering or hoisting gear, comprise housing, be fixed on the underframe of outer frame bottom, be arranged in parallel with underframe, and liftable upper frame is arranged with chute respectively on the same plane of underframe and upper frame, be provided with crane between described underframe and the upper frame, the end of crane is provided with the rubber tire that can insert in the described chute, is provided with in the bottom of described crane to promote the electric pushrod that described crane moves.
Also be provided with the displacement transducer fixed leg on described crane, the displacement transducer fixed leg is provided with displacement transducer, and displacement transducer is electrically connected with a circuit control panel and display.
Same end at described chute is provided with the L type member that is used for fixing rubber tire.
Described crane comprises by 4 hinged two X type supports that constitute of pole and 4 poles connecting two X type bracket end.
The utlity model has following advantage: the head position place that this occipitalia lowering or hoisting gear can be installed in various massage armchairs, leisure chaise longue, leisure bed, electric up-down chair, product such as electric up-down bed; The angle that electric pushrod promotes under the control of circuit board in the crane between two poles changes, and crane can be controlled upper frame by the end rubber tire and upwards rise or fall downwards, thereby has realized the function of independent adjusting head height; By displacement transducer is set, can also be as required, the height of control lifting; By L type member is set, it is more steady to rise frame.
