Description

The adjustable for height sick bed of a kind of electrodynamic type head of a bed

Technical field

This utility model relates to the sick bed of hospital, is specially the adjustable for height sick bed of a kind of electrodynamic type head of a bed.

Background technology

At present, the sick bed majority applied clinically has the head of a bed or tailstock and to steeve adjustable for height function, when the head of a bed or tailstock need be raised, by rotating the distant bar be arranged on bedstead, and then drive the linkage be connected with the head of a bed or tailstock can realize the object of altitude mixture control.This kind of sick bed facilitates the nursery work of families of patients and nurse to a certain extent, but it compares effort in adjustment process, and patient can not operate separately usually.In addition, part sick bed is steady not in adjustment process, easily causes the damage of adjustment structure.

Utility model content

The purpose of this utility model is to provide the adjustable for height sick bed of a kind of electrodynamic type head of a bed, and it highly can regulate steeving of the head of a bed, and in adjustment process, the head of a bed rises steadily, and patient can complete operation separately, uses convenient.

For achieving the above object, the technical solution of the utility model is: the adjustable for height sick bed of a kind of electrodynamic type head of a bed, comprise bedstead and be arranged on the bed board on bedstead, described bed board is made up of the fixed bed board and mobile bed plate laying respectively at tailstock and the head of a bed, chain connection between fixed bed board and mobile bed plate, be provided with in the below of bed board for regulate mobile bed plate steeve height electric adjusting mechanism, this electric adjusting mechanism comprises the motor be arranged on bedstead, decelerator, screw mandrel, and to be hinged on bottom mobile bed plate and symmetrically arranged two support bars, motor coaxle drives two decelerator motions, the hollow output shaft of two decelerators respectively connects a screw mandrel, the two ends of screw mandrel are rotatably supported in screw mandrel bearing that bedstead is arranged, two screw mandrels be arranged in parallel along bedstead length direction, two screw mandrels are equipped with the nut be mated, two nuts are hinged with the bottom of two support bars respectively.

One end that described bedstead is positioned at the head of a bed is provided with the controller for controlling machine operation.

Beneficial effect: this utility model adopts double lead nut body to drive two support bars hinged with the head of a bed mobile bed plate move, and then realization to be steeved adjustment highly to the head of a bed.Two decelerators drive rotations that two screw mandrels are driven by motor coaxle, ensure that the synchronous operation of two screw mandrels, make head of a bed mobile bed plate more steady in height adjustment.Motor is controlled by controller, facilitates the independent operation of patient.

Detailed description of the invention

As shown in Figure 1, the adjustable for height sick bed of a kind of electrodynamic type head of a bed, the bed board comprising bedstead 1 and be arranged on bedstead 1, described bed board is made up of the fixed bed board 2 and mobile bed plate 3 laying respectively at tailstock and the head of a bed, chain connection between fixed bed board 2 and mobile bed plate 3, be provided with in the below of bed board for regulate mobile bed plate 3 steeve height electric adjusting mechanism, this electric adjusting mechanism comprises the motor 4 be arranged on bedstead, decelerator 5, screw mandrel 6, and to be hinged on bottom mobile bed plate 3 and symmetrically arranged two support bars 7, motor 4 Driven by Coaxial two decelerators 5 move, to ensure the synchronous axial system of two screw mandrels 6, the hollow output shaft of two decelerators 5 respectively connects a screw mandrel 6, screw mandrel 6 can adopt trapezoidal screw, key is adopted to be connected between hollow output shaft with screw mandrel 6, the two ends of screw mandrel 6 are rotatably supported in the screw mandrel bearing 8 of setting on bedstead 1, at the head of a bed of bedstead 1 and tailstock, two screw mandrel bearings 8 are respectively set, two screw mandrels 6 be arranged in parallel along bedstead 1 length direction, two screw mandrels 6 are equipped with the nut 9 be mated, two nuts 9 are hinged with the bottom of two support bars 7 respectively.

Under motor 4 drives, drive two screw mandrel 6 synchronous axial system by two decelerators 5, and then nut 9 is moved on screw mandrel 6, thus promote the rotation of mobile bed plate 3 by the support bar 7 hinged with nut 9, mobile bed plate 3 head end is elevated.Change the rotation direction of motor 4, mobile bed plate 3 can be made to recover normal position.The controller that one end setting that can be positioned at the head of a bed at bedstead 1 works for controlling motor 4, comprises the rotating of control motor 4, start stop operation.During client need regulation bed grease head highness, undertaken operating by the control knob on controller, it can operate separately.Further, one is rotated number of turns sensor for measuring screw mandrel 6 can be set in the end of screw mandrel 6, the lap signal of screw mandrel 6 is passed to described controller by this sensor, controller receives this lap signal, and lap information is converted to mobile bed plate 3 steeve height information, this elevation information is presented by the display floater of controller, more intuitively.Like this, in some treatment of diseases, the height of steeving of fine adjustment mobile bed plate 3 can be accomplished.
