Drive mechanism 2 comprises worm screw 20 and worm gear 21, is installed in the peripheral frame 10 of bedstead 1, and the worm screw 20 in bed side two frames 10 is joined with actuator 3.Main motor-driven master worm screw rotation in the driving mechanism drives worm screw 20 runnings by worm gear 21, drives slide block (30 respectively by worm screw 20,31) radially slide, final drive shaft 331 is by worm screw 20 driven rotary simultaneously, and final drive shaft 331 drives cylinder 330 rotations by belt, finishes the work; Require the various parameter strictnesses of worm screw identical.

Actuator 3 comprises slide block (30,31), rise and fall fork 32, Storage case 33, two of slide blocks (30,31), on establish cover hand-hole 301, be enclosed within respectively on the worm screw 20 in the both sides bed frame 10, be provided with wrom tooth in the cover hand-hole 301 and worm screw 20 is meshing; Slide block 30 32 links to each other with the fork that rises and falls, and rises and falls and pitches 32 yoke (320,321) forward, upwards be convexly curved, and slide block 31 inner surfacies are provided with groove 310, and groove 310 is trapezoidal bending setting in slide block 31, and groove 310 is connected with steady pin sheet 13; Steady pin sheet 13 is plates, head 130 matches with the breach 140 of the plush copper 14 of cross bar 11, afterbody 131 has an opening 1310 to be connected with the recess 101 of bed frame 10, opening 1310 two side columns 1311 are with spring 1312, on the lamellar dignity, upwards hold up a column steady pin 132, steady pin 132 is connected with the groove 310 of slide block 31.Be placed with Storage case 33 between slide block 30 and the slide block 31, Storage case 33 is a rectangular body, box frame 333 firmly links to each other with slide block 30, slide block 31, be provided with many demountable cylinders 330 in the Storage case 33, cylinder 330 and final drive shaft 331 constitute cylinder drive mechanism (330,331), final drive shaft 331 is installed in the slide block 31, final drive shaft 331 1 ends are meshing by worm gear 332 and worm screw 20, and the other end joins by belt and many cylinders 330, and sheet, mattress just volume are placed on the cylinder 330.

Two slide blocks (30,31) are done the footpath and are slided forwards, backwards along with worm screw 20 rotations.The fixed fork 32 that rises and falls in slide block 30 belows has a breach 323, freely hangs down yoke (320 for cross bar 11,321) the two ends circular arc is packed up, and confession cross bar 11 steadily hangs down or rises yoke (320,321) terminal is provided with the end and colludes, the usefulness of unclamping steady pin 132 for top cross bar 11 slightly; Borings are fluted 310 in the slide block 31, and groove 310 two ends are near trapezoidal plush copper 14, and interlude is away from trapezoidal plush copper 14, steady pin 132 slides in groove 310, along with the position difference of groove 310, steady pin sheet 13 injects or extracts out trapezoidal plush copper 14 breach 140, with fixing or unclamp cross bar 11; Two slide blocks (30,31) fixing Storage case 33 between, 2 pairs of poles that can rotate freely 332 of device on box frame 333 end faces, pole 332 and cross bar 11 levels, pole 332 is played interim supporting role, respectively install 2～3 removable cylinders 330 before and after the box frame bottom, cylinder 330 is by the belt transmission rotation, and retractable sheet, cotton are filled up and air cushion respectively; Each one of Storage case 33 front and back stop push rod, when work finish Storage case move to the bed an end time, stop push rod and promote gauge tap, main motor shuts down, lifting motor and inflation motor are started working, lifting motor stops (lifting motor work earlier is promoted to operating position-0.9 meter with the bed body before the main motor rotation) after the bed body is dropped to fixed position (0.6 meter), inflation driven by motor compressor is inflated inflatable packer, stops automatically after finishing.Main motor, lifting motor and inflation motor adopt general technology.

Clean long 2.0 meters of this utility model, 0.7 meter of clear span; 2.5 meters of length overalls, 1.0 meters of beam overalls; Bed surface high 0.6 meter (transferring to 0.9 meter during operation automatically), 1.4 meters of height overalls.

Operation principle is as follows: by 20 rotations of motor-driven worm screw, drive two worm screws in bed both sides 20 with the speed rotation, make two slide blocks (30,31) make longitudinal horizontal movement, the fork 32 that rises and falls of a slide block 30 begins sliding nearly first cross bar 111.This moment, all cross bar 11 1 ends all were enclosed within on the hanging stick 12, and the other end (movable end that trapezoidal plush copper 14 is promptly arranged) is fixed on the frame 10 in plush copper 14 breach 140 because of steady pin sheet 13 is inserted in, human weight on the together support implantation.Since first cross bar 111, the slightly movable cross bar 111 of jack-up of fork 32 bottoms rises and falls during slide block 30 motions, unclamp between the breach 140 of trapezoidal plush copper 14 and the steady pin sheet 13, another slide block moves to trapezoidal groove 310 stage casings (promptly leave trapezoidal plush copper 14 a section) 31 this moments, steady pin sheet 13 is along with the steady pin 132 that is inserted in the groove 310 is pulled to one side of leaving trapezoidal plush copper 14, steady pin sheet 13 is extracted out from the breach 140 of trapezoidal plush copper 14, the plush copper 14 of cross bar 111 loses the fixing of steady pin sheet 13, because of action of gravity leans against the fork 32 yoke 320 circular arc limits formerly of rising and falling downwards, along with slide block 30 travels forward, cross bar 111 slowly slides into fork 32 bottoms of rising and falling downwards by breach 323; In this position, with two slide blocks (30,31) fixing and with two slide blocks (30,31) each cylinder 330 rotates in the Storage case 33 of Hua Donging, the clean sheet (bedding) that twists on the cylinder 330 slowly relays out, one of the sheet of need changing (bedding) is fixed on another cylinder 330 and takes in along with cylinder 330 rotates slowly to change: this moment slide block (30,31) move forward, rise and fall fork 32 on yoke 321 garden arc limit, back jack-up cross bar 111 slowly, the trapezoidal plush copper of cross bar 111 injects the breach 101 of bed frame 10, the fork 32 that rises and falls omits jack-up cross bar 111 in back yoke 321 terminals, trapezoidal groove 310 is being held in the mouth the position that steady pin 132 moves to approaching trapezoidal plush copper 14 at this moment in the slide block 31, steady pin sheet 13 is injected the breach 140 of trapezoidal plush copper 14, the plush copper 14 of cross bar 111 is fixed on the bed frame, finish the action of article one cross bar 111.Slide block (30,31) slides to the other end from an end of bed, finishes the work of the mattress that all more changes the sheet, and the terminal of the clean sheet of just having changed (bedding) also is fixed on the cylinder 330, need not handle, and when treating next the replacing the above-mentioned reversing of motion is got final product; Sheet (bedding) under changing takes off processing together with cylinder 330, disable motor, end-of-job.
