Abstract

The utility model relates to a sickbed, which comprises castors, a chassis, a transfer bed surface composed of a supporting plate, a bearing seat, a roller and a bed surface, a lifting transmission portion composed of a hand wheel, a bidirectional screw rod, a swing rod, a connecting rod and a draw rod, and an auxiliary function portion composed of columns and hooks. The lifting transmission portion is arranged between the moving bed surface and the chassis. The hand wheel is rotated to drive the bidirectional screw rod in rotation. The swing rod is swung driven by a nut, in order to realize lifting of the bed surface on the top of a transferring vehicle and regulate the height to adapt to different requirements of the height of a work top. Since the swing rod, the draw rod, the chassis and the supporting plate form two parallelogram mechanisms, the utility model guarantees no inclination of the vehicle top, ensures smooth transfer of the patient, and saves labor.

Description

Sickbed

This utility model belongs to the equipment of transferring patient, relates in particular to a kind of Sickbed.

At present, when handicapped patient or critical patient seek medical advice in hospital, mostly use the horizontal sliding car to finish patient's turnover, this horizontal sliding car car face height can not be adjusted, do not adapt to varying mesa height requirements of one's work such as sick bed, examining table, operating-table, when therefore using, need to lift by the people, it is this that to carry on the transfer movement of carrying off very not steady, easily the particularly postoperative patient of patient is damaged, influence patient's rehabilitation, reduce the safety of patient's circular flow, also increase patients' relatives and medical personnel's labor intensity simultaneously.

The purpose of this utility model is to provide a kind of Sickbed, and its car face height can arbitrarily be adjusted, and adapts to the needs of different occasions, and patient moves steadily between table top simultaneously, thereby overcomes the defective that present hospital uses the horizontal sliding car.

This utility model adopts following technical scheme:

Sickbed of the present utility model, comprise castor, the chassis, bed surface and the miscellaneous function part of forming by column and hook, bed surface is row's cylinder 11 that two ends is equipped with rolling bearing, be contained on the rolling bearing pedestal of two strips, and with the middle part of its overall fixed at supporting plate, make the both sides of bearing block stretch out supporting plate, fix two bed surfaces at the two ends of supporting plate, with conveyer belt one row's cylinder is surrounded and the mobile bed surface of composition, the lifting running part is housed between the supporting plate of chassis and mobile bed surface, the lifting running part is by handwheel, fork, connecting rod, pull bar, nut and two-way screw mandrel are formed, with handwheel, nut and two-way screw mandrel are installed in forms two-way leading screw and nut mechanism on two supports, two stands is fixed on the chassis, 4 forks are installed on the chassis, bearing pin on the nut is placed in the chute of fork, two connecting rods with the fork equal in length are installed before and after the chassis opposite side, 6 connecting rods of same length are loaded on the supporting plate bottom, again with these 6 connecting rods respectively with the chassis on 4 forks installing be connected with bearing pin with 2 connecting rods, a pull bar is installed by central authorities at upper and lower strut, conveyer belt is made by the intensified nylon material, and column and hook are installed in bed surface edge, right side.

Specifically narrate embodiment below in conjunction with accompanying drawing:

Fig. 1 is a stereochemical structure exploded view of the present utility model

Fig. 2 is the A-A face cutaway view of Fig. 1

Among the figure, 1 castor, 2 chassis, 3 handwheels, 4 two-way screw mandrels, 5 nuts, 6 forks, 7 connecting rods, 8 supporting plates, 9 bed surfaces, 10 bearing blocks, 11 cylinders, 12 pull bars, 13 columns, 14 hooks, 15 conveyer belts, 16 supports

During enforcement, as shown in Figure 1,4 castors 1 are installed on the chassis 2, supporting as tote cart, two direction-casters are selected in the left side for use, two caster wheels are selected on the right side for use, so that tote cart promotes laborsaving and turns to flexibly, the row's cylinder 11 that two ends is equipped with rolling bearing is contained on two strip rolling bearing pedestals 10, and with the middle part of its overall fixed at supporting plate 8, make the both sides of bearing block 10 stretch out supporting plate 8 (as shown in Figure 2), fix two bed surfaces 9 at the two ends of supporting plate 8, the conveyer belt made from the intensified nylon material 15 surrounds row's cylinder, form mobile bed surface, with handwheel 3, nut 5 and two-way screw mandrel 4 are installed on two supports 16, form two-way leading screw and nut mechanism, two stands 16 is fixed on the

chassis

2,4 forks 6 are installed on chassis 2, bearing pin on the nut 5 is placed in the chute of fork 6, two connecting rods 7 with fork 6 equal in length are installed before and after chassis 2 opposite sides, 6 connecting rods 7 of length equally are loaded on the bottom of supporting plate 8, again with these 6 connecting rods 7 respectively with chassis 2 on 4 forks 6 of installation be connected with 2 connecting rods, 7 usefulness bearing pins, a pull bar 12 is installed by central authorities at upper and lower strut, and bed surface edge, right side is equipped with column 13 and hook 14.During use, tote cart is shifted onto by sick bed or the operating board, and tight with it row is close together, rotate handwheel 3, adjust car face height, as shown in Figure 2, make the B face be adjacent to the workbench edge, the A face is pressed on the work top, at this moment, and the handover part at tote cart bed surface middle part (two bearing blocks and the cylinder that surrounds by conveyer belt), part reaches on the work top, rotate handwheel 3 and drive two-way screw mandrel 4 rotations, under the promotion of nut 5, make fork 6 swings, realize the elevating movement of tote cart top bed surface by fork 6 and connecting rod 7, thereby regulate height, patient is shifted onto on the workbench from tote cart, or move on the tote cart from workbench, because the effect of rolling bearing and conveyer belt, make the above-mentioned handover process that pushes away or draw steadily strong, more laborsaving and finish patient's turnover safely, hook 14 is used to hang transfusion bag or the medicine bottle that patient uses.Patient's tote cart of the present utility model, fork 6, connecting rod 7, pull bar 12 and chassis 2, supporting plate 8 is formed two parallel-crank mechanisms, guarantee that the tote cart end face does not tilt, the composite structure of being made up of two parallelogrames can make the caused elevating movement of fork 6 swings be amplified again, shortened the length of screw mandrel 4, can make the rapid lifting of tote cart end face to adapt to the needs of different operating occasion height, row's cylinder 11 that rolling bearing is equipped with by two ends in its top is transmitted is with 15 to surround, in the course of the work, the gravity that patient body weight forms has strengthened the frictional force of conveyer belt and cylinder surface, as long as push hard or draw patient's cylinder just to roll a little, transmit the steady and safety of patient like this thereby make.

In sum, patient's tote cart of the present utility model, novel in design, reasonable, practical, safety again easy to use overcomes the defective of traditional product, reaches design purpose.
