Abstract

The utility model provides a micro mechanical patient bed riser relating to a device, which can increase or decrease the patient bed, comprising a motor, a screw, a shaft, a medium hinge shaft, a screw barrel shaft, a roller, internal and external scissors, an upper roller, a chassis, a platform and an electrical limit switch. The platform of the utility model is arranged below the both ends of the patient bed. When in use, press the button on the end of the soft cable, the motor moves clockwise, the internal and external scissors furl upward and inward along the vertical direction, the patient bed rises to normal lying position; press the button again, the motor moves counterclockwise, the internal and external scissors furl outward and downward along the horizontal direction, the patient bed falls down to a desired height, so the riser is suitable for on-bed and off-bed actions and massage care of the patient. The utility model has the advantages of simple structure, convenient operation, and strong applicability. While not in use, the internal and external scissors furl upward and inward along the vertical direction and the patient bed rises to normal lying position.

Description

The miniature sick bed lifter of mechanical type

Technical field this utility model relates to a kind of device that sick bed can be risen, descends.

The sick bed of the present hospital of background technology can only two lifting, makes patient or is in to crouch by crouching, or raise lower limb, and do not have the sick bed of whole energy lifting.Because sick bed can not descend, cause the inconvenient bunk bed of old, young patient; Medical personnel's inconvenience is stood up patient, and patient is cleaned, massages or nursing etc.

Design for this reason a kind of can be with the whole device that descends of sick bed so that get in and out of bed, clean, massage or nurse necessary.

The summary of the invention the purpose of this utility model is according to above-mentioned present situation, aim to provide a kind of simple in structure, easy to operate, the miniature sick bed lifter of mechanical type that sick bed can be risen overally and descend.

Implementation of the present utility model is, the miniature sick bed lifter of mechanical type, inside and outside fork 9, the 5 upper and lower ends of cutting that connected by middle dumpling axle 13 connect with chassis 11, platform 4 dumplings respectively, and the upper roller 14 of upper and lower end, roller 1 place the chute on platform 4, chassis 11 respectively.The motor 10 that is connected with button is housed on the chassis, and motor drives roller 1 by bearing 8, shaft coupling 7, screw rod 3, swivel nut axle 2.The swivel nut axle with in to cut fork 9 support arm hinged.There is electric limit switch at the chute two ends.

This utility model platform 4 is contained in sick bed two ends belows, in cut between fork 9 upper ends and platform and be connected by upper roller 14, chute, upper roller plays motion guide, minimizing resistance.For increasing the lift that rises of platform minimum point, alleviate the motor starting load, cut fork 5 upper ends and the platform 4 dumpling places of connecing outward and also be provided with power assistant spring 12.

During use, the button of the flexible cable termination that links to each other with motor places on the sick bed, patient or medical personnel press button, motor is clockwise, motor is by bearing 8, shaft coupling 7, coupling band 6, screw rod 3 reaches swivel nut axle 2 with power, swivel nut axle 2 is converted to rectilinear motion with screw, the arm of cutting fork in making moves upward, the roller 1 of cutting the fork lower end in the swivel nut axle drives again simultaneously inwardly rolls in the chute of chassis, cutting the upper roller 14 of sticking end outward also inwardly rolls in the chute of platform 4, in, cutting fork outward vertically makes progress, inwardly draw in, sick bed rises to normal clinostatism (see figure 4), this moment, the electric limit switch at chute two ends disconnected, and motor is no longer clockwise, and rising stops.

In the time of sick bed need being descended, press button, motor counter-rotating, in cut fork arm move downward, cut in the swivel nut axle drives again the fork lower end roller 1 in the chute of chassis to outer rolling, simultaneously outer cut stick end upper roller 14 in the chute of platform 4 also to outer rolling, inside and outside cut the fork along continuous straight runs, outwards draw in downwards, sick bed descends, (see figure 1) when dropping to lowest order, the electric limit switch at chute two ends disconnects, and motor no longer reverses, and decline stops.

As the need sick bed not when highest order or the lowest order, as long as rise on one's sick bed or when dropping to desired height, release button, motor no longer rotates, coupling band 6, screw rod self-locking, sick bed location, get in and out of bed medical personnel's treatment, scouring, massage or nursing etc. to be fit to patient.

This utility model is simple in structure, easy to operate, the suitability is strong.

The specific embodiment

This utility model is made of motor 10, screw rod 3, shaft coupling 7, swivel nut axle 2, roller 1, inside and outside

fork

9,5, upper roller 14, chassis 11, the platform 4 etc. cut.Motor connects power supply by flexible cable, button.Press button, motor is clockwise, and motor makes the inside and outside fork of cutting vertically make progress, inwardly draw in by bearing 8, shaft coupling 7, coupling band 6, screw rod 3, coupling band 2, link rod 14, pulley 13, and sick bed rises to normal clinostatism; Press button again, the motor counter-rotating, inside and outside cutting pitched outside, the gathering downwards of along continuous straight runs, and sick bed drops to lowest order.Release button midway, sick bed also can rise or drop to desired height.

Claims
