The specific embodiment
Below in conjunction with accompanying drawing concrete structure of the present utility model and principle are described further.
As shown in the figure, but the stretcher of stair activity of the present utility model, it has the front leg strut and the rear support leg of movable stretcher 5 and belt wheel, two groups of wheels are installed in front-wheel strut 13 two ends respectively by wheels bearing 1, left front supporting leg 801 is connected on the front-wheel strut 13 of described wheels inboard with the lower end of right front supporting leg 8, and the two ends of front rail 12 are connected to left front supporting leg 801 and right front supporting leg 8 middle parts; Other has two groups of wheels to be installed in trailing wheel strut 9 two ends respectively by wheels bearing 1, left back supporting leg 301 is connected on the trailing wheel strut 9 of described wheels inboard with right back supporting leg 3 lower ends, and the two ends of rear transverse rod 10 are connected to left back supporting leg 301 and right back supporting leg 3 middle parts; Left front supporting leg 801 upper ends and left back supporting leg 301 upper ends are hinged at 11 left ends of setting a roof beam in place, right front supporting leg 8 upper ends and right back supporting leg 3 upper ends are hinged at 11 right-hand members of setting a roof beam in place, cross bar 401 two ends, a left side are hinged respectively at left front supporting leg 801 and left back supporting leg 301 middle parts, and right cross bar 4 two ends are hinged respectively at right front supporting leg 8 and right back supporting leg 3 middle parts; The lower plane middle part of movable stretcher 1 is provided with and can clamps 11 the draw-in groove 6 of setting a roof beam in place; Described wheels are made up of 3 steamboats that are mutually 120 degree angles that are installed on the wheels bearing 1, and 3 steamboats are equal to the distance of wheels bearing 1; Above-mentioned front leg strut 8,801 length are greater than rear support leg 3,301 length, left side cross bar 401 comprises cross bar cover 402 that has bolt button pin 403 and the inserted link that has pin-and-hole 404 405 that is sleeved in the cross bar cover 402 with right cross bar 4, movable stretcher 5 middle parts are provided with stretcher handrail 7, movable stretcher 5 two ends are provided with four stretcher handles 2 altogether, stretcher handle 2 bottoms cover is buckled with semicircle stretcher lower limb 202, stretcher lower limb 202 can be rotated down 90 degree around fixed axis 201, and stretcher handle 2 is provided with kayser 203.
The general every rank of stairway step height is 15-18CM, wide 20-30CM at present, and for adapting to this situation, when manufacturing stretcher, the radial design of steamboat is 5-6CM in the wheels, and the distance at two steamboat centers is 15-18CM.
When using this stretcher, the draw-in groove 6 of movable stretcher 5 by the middle part is installed in sets a roof beam in place on 11, and the angle of movable stretcher 5 can artificially be controlled in pushing course, can make patient remain horizontal position.A left side cross bar 401 and right cross bar 4 is owing to be that inserted link 405 is installed in the cross bar cover 402 and fixing by bolt button pin 403, can fasten button pin 403 length that left cross bar 401 and right cross bar 4 are regulated in the position of pin-and-hole 404 on inserted link 405 by adjusting, with the height of adjusting movable stretcher 5 and the distance between the wheels of front and back.When stretcher promoted on the plane, every group of wheels had the motion that lands of two steamboats.When stretcher when stair promote downwards, steamboat A14 at first steps on sky, at this moment, wheels can be that the strong point is rotated down with steamboat B15 just, and steamboat A14 and steamboat C16 can land at next step again, push away forward again, steamboat C16 can step on sky again, wheels can be that the strong point is rotated down with steamboat A14 just, and steamboat 16C and steamboat B15 can land at next step again, and promotion on stair is finished in alternating movement repeatedly like this.When stretcher when stair upwards promote because the stopping of step, wheels can serve as axially to go up upset with the steamboat that is blocked, and realize climbing the building and move.
When left cross bar 401 and right cross bar 4 were decontroled fully, movable stretcher 5 can lie on front-wheel strut 13, trailing wheel strut 9, front rail 12, the rear transverse rod 10.At this moment stretcher just becomes the horizontal sliding stretcher, and it is convenient to move patient so in the plane.Can be rotated down 90 degree to stretcher lower limb 202 around fixed axis 201 after static, use fixedly stretcher lower limb 202 of kayser 203, so just can do interim sick bed to stretcher and use.
The required kayser 203 of this utility model is a conventional design, by those skilled in the art of the present technique are known, no longer encyclopaedizes.
