Description

Steady lifting cart for patients

This utility model relates to a kind of patient's of transporting go-cart, especially refers to the special-purpose go-cart of inconvenient removing patients such as paralytic, patients after surgery.

At present, common hospital transports patient's go-cart (bed or chair) can not lifting, and especially patient moves from operating-table and transports in the go-cart, often needs the lift to move of choosing, and both inconvenient, patient is also uncomfortable, but also the healing of easy damaged wound.Though also occur with worm drive as terminal driving member, support the bed of go-cart or the lifting cart of chair, but, because the rigidity worm drive connect, impact when starting, shake when meshing the impact that brings in the space and promoting go-cart etc. all can make disease feel under the weather, be unfavorable for the improvement of patient's state of an illness, can not reach transhipment patient's purpose.

In view of this, the purpose of this utility model is that a kind of steadily patient trolley of lifting will be provided, and bed is held hung on the flexible end driving member of go-cart elevating mechanism.

The purpose of this utility model is achieved in that it comprises car bearing support, bed chair, worm-drive, on the axle of worm gear, be provided with a capstan winch, be provided with a fixed pulley on car bearing support top, also be provided with the one end and be connected on the capstan winch, and walk around above the fixed pulley, be connected flexible suspender belt on the chair with its other end then.

Owing to adopt such scheme: can transport patient easily, and make patient feel comfortable, help nursing to patient.

Below in conjunction with drawings and Examples this utility model is further specified.

The main body sketch map of Fig. 1 this utility model embodiment.

The worm-drive system diagram of Fig. 2 this utility model embodiment.

The flexible suspender belt connection diagram of Fig. 3 this utility model embodiment.

Among the figure: 1, car bearing support, 2, the bed chair, 21, hook, 22, backrest, 23, protecting band, 24, seat board, 3, worm-drive, 31, motor, 32, worm gear, 34, bevel gear, 35, handle, 4, capstan winch, 5, fixed pulley, 6, flexible suspender belt.

Present embodiment comprises car bearing support 1, bed chair 2, worm-drive 3, capstan winch 4, fixed pulley 5 and flexible suspender belt 6.

Capstan winch 4 is to be installed on the worm-wheel shaft with worm gear 33, and promptly capstan winch 4 rotates synchronously with worm gear 33.

Fixed pulley 5 is to be articulated on the car bearing support 1 top transverse axis, can rotate with moving of flexible suspender belt 6, and support bed chair 2.

Flexible suspender belt 6 is flexible flat belt, in the fixing wedge groove of one end with capstan winch 4, and stretch out, walk around fixed pulley 5 outer rims contacts (fixed pulley 5 outer rim summits are higher than capstan winch 4 outer rim tops) with capstan winch 4 outer rims, be connected to then on the hook 21 of a chair 2 upper ends, the support bed chair 2 hangingly.

Worm-drive 3 is ends that connected worm screw 32 by motor 31, drive worm screw 32 and rotate, worm screw 32 and worm gear 33 engagements (worm and gear of a pair of self-locking), capstan winch 4 again with worm gear 33 coaxial rotation, flexible suspender belt 6 is elongated or shortened, rise or descend thereby drive bed chair 2.Simultaneously worm screw 32 other ends are linked in sequence and several bevel gear 34(is transmitted distance, becomes myriabit), until connecting one handle 35, therefore, except that driven by power, also available crank handle 35 drives worm screws 32, handle 35 desirable F or fold when electronic; Whole worm-drive 3 is supported on the car domination frame 1 vertical frame.

Bed chair 2 hangs on the hook 21 with the protecting band 23 that is connected seat board 24, backrest 22 respectively, supports and the protection patient, can be used as seat; As long as backrest 22 is set level the bed that just becomes support and protection patient.In addition, for the sake of security, limit switch is equipped with in seat board 24 bottom surfaces of bed chair 2, and limit switch is run into barrier in bed chair 2 moves, and as ground, just the circuit of motor 31 is disconnected, motor 31 shuts down at once, and bed chair 2 stops to move.

Car bearing support 1 constitutes the channel-section steel structure-steel framing for upper and lower beam stretches out forward with vertical beam, and roller is contained in F beam bottom.
