Abstract

The utility model discloses a simple automatic hospital bed, comprising a rotatable back, a supporting bar which can slide, two rotary bars which are connected with the two sides of the bed, a rotary handle which is connected with the rotary bar, a screw rod which can drive the rotary handle to rotate and a bearing which can drive the screw rod to extend and contract. A forward/ reversible rotating dynamoelectric machine is arranged below the bed head, and a speed reducer is driven to rotate forwardly and reversely by the forward/ reversible rotating dynamoelectric machine via the coupling of gears. The speed reducer drives the bearing to rotate via the coupling of gears. An elevator switch is arranged at a position which is adjacent to the bed head and connected with the forward/ reversible rotating dynamoelectric machine. For the simple automatic hospital bed of the utility model, the patient can adjust the angle of the back of the hospital bed freely without being attended so long as the elevator switch is pressed slightly. Different requirements for the angle of the back of the patient that is in different conditions can be satisfied. At the same time, by using the simple automatic hospital bed, the turning of the rotary handle by man can be omitted and the disadvantage that the adjusting of the back is difficult in the prior art is overcome.

Description

Simple and easy hospital bed

Technical field

This utility model relates to a kind of sick bed, specifically, relate to a kind of patient can be self-regulating the sick bed of backrest height, lifting.

Background technology

Traditional sick bed near head of a bed sixth to a three/place, has a backrest that can carry out lift adjustment.This backrest one end is fixed near head of a bed sixth to three/place, the other end support bar of band pulley.Support bar band pulley end model of action supports the liftable backrest, the other end is fixedly connected on dwang, the dwang two ends are connected on two bedside of bed, one fixedly connected handler is arranged on the dwang, the other end of handler is movably connected on can be to the head of a bed, the flexible screw rod of tailstock, this screw rod other end is connected on the hand bearing of tailstock, and a wind is arranged on the hand bearing.It is flexible to the head of a bed, tailstock that rotary handle crank, hand bearing drive screw rod, and the flexible drive handler of screw rod rotates, handler rotates and drives the dwang rotation, dwang rotates and drives the support bar rotation, and support bar rotates the promotion backrest and rotates, and promptly realizes the lift adjustment of backrest.This sick bed needs artificial rotation wind, could realize the lift adjustment of sick bed backrest, the demand of different backrest angles such as satisfy that patient lies, leans on.Generally, patient can not, also ability is shaken wind, regulates backrest angle.Under the situation that does not have patient to accompany, patient will be not being met to the demand of backrest lifting, adjusting backrest angle, simultaneously, manually shake wind and will comparatively take a lot of trouble, requires great effort, and use inconvenient.

Summary of the invention

Goal of the invention of the present utility model is to be to overcome above-mentioned deficiency, provides a kind of and saves trouble, laborsaving, easy to use, and patient can regulate the simple and easy hospital bed of backrest lifting voluntarily.

For achieving the above object, simple and easy hospital bed of the present utility model comprises rotatable backrest, the screw rod of slidably support bar, the dwang that is connected in a both sides, the handler that is connected in dwang and the rotation of drive handler, the flexible bearing of drive screw rod, one suitable, contrary electric rotating machine is arranged under the head of a bed, this motor by gear coupling drive reductor forward, counter-rotating, the reductor back of slowing down drives bearing by gear coupling and rotates;

Near head of a bed position, direction switch is housed, be connected on suitable, the contrary electric rotating machine.

The simple and easy hospital bed of this utility model is installed suitable, contrary electric rotating machine at sick bed near head of a bed position, this motor is controlled it forward or backwards rotation by the direction switch that is positioned on bedside, drive reductor forward or backwards rotation, further drive bearing forward or backwards rotation, bearing forward or backwards rotation drive screw rod to the head of a bed, berth telescopic moving, the telescopic moving of screw rod drives handler and rotates, handler rotates and drives the dwang rotation, dwang rotates and drives the support bar rotation, support bar rotates and promotes the backrest rotation, promptly realizes the lift adjustment of backrest.The simple and easy hospital bed of this utility model, neglected down patient, as long as patient presses direction switch gently, just can regulate the angle of sick bed backrest freely, satisfy patient's different requirements to backrest angle under different conditions.Simultaneously, adopt the simple and easy hospital bed of this utility model, also saved and manually shaken wind, overcome bothersome, the effort of backrest adjusting in the prior art, use inconvenient shortcoming.
