Description

The Height Adjustable stretcher of supporting leg
Technical field
The present invention relates to medical salvage device technical field, specifically is a kind of supporting leg adjustable height stretcher.
Background technology
Stretcher on the market can not satisfy the uneven occasion in open-air ground or highly need the user demand of adjusting situation now.Existing simultaneously stretcher bottom is bigger, moves inconvenience, and shank can't pack up, so stretcher need take very big space.Also occurred hand elevating stretcher car on the market, but its all supporting legs are to regulate simultaneously, can not realize the independent regulation of four lower limbs; And its structure is complicated; Involve great expense, and be only applicable to the situation of indoor ground grading, can not satisfy the needs of open-air relief.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the present invention provides a kind of supporting leg adjustable height stretcher, and the stretcher shank can be realized independently regulating fast, can also be stowed in the bottom of stretcher simultaneously in adjusting shank later, has saved the space.
The present invention realizes with following technical scheme: the Height Adjustable stretcher of a kind of supporting leg comprises the stretcher main body, is installed in the handrail on the stretcher main body and is used to support the supporting leg of stretcher main body; Supporting leg adopts the supporting leg that highly can regulate, and the bottom of each supporting leg all is equipped with runner; Described supporting leg comprises lower limb and is installed in the following lower limb that lower limb inside can move up and down; Bottom at last lower limb is fixed with positioner, has on the positioner and hole that following lower limb matches, and following lower limb passes hole on the positioner and packs that to go up lower limb inner into; Have a plurality of draw-in grooves from top to bottom on the following lower limb, be set with ring-like brake(-holder) block on the infra lower limb, overlap ring-like brake(-holder) block and pass positioner and be connected with DOCK LEVELER; The hands that the supporting leg level of packing up is placed on stretcher main body below is installed between supporting leg and the stretcher main body pinches the receipts leg device.
The invention has the beneficial effects as follows: 1, the height of independent regulation supporting leg fast, so that use in different occasions; 2, utilize hands to pinch the receipts leg device and can quick and conveniently pack up supporting leg, time saving and energy saving; 3, simple in structure, easy to operate, be easy to promote.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is a structure chart of the present invention;
Fig. 2 supporting leg collapsed configuration sketch map;
Fig. 3 supporting leg and stretcher main body syndeton sketch map;
Fig. 4 is the partial enlarged drawing of Fig. 1.
Among the figure: 1, runner, 2, supporting leg, 21, go up lower limb, 22, lower limb down, 3, hands pinches the receipts leg device, 31, drive pinion; 32, transmission sector gear, 33, handle, 34, rotating shaft, 4, handrail, 41, the handrail connecting rod, 42, bar; 43, handrail support bar, 5, the stretcher main body, 6, pin, 7, positioner, 8, DOCK LEVELER; 9, compression spring, 10, stopper slot, 11, draw-in groove, 12, overlap ring-like brake(-holder) block, 13, reel bar.
The specific embodiment
Like Fig. 1, shown in Figure 4, the Height Adjustable stretcher of supporting leg has a stretcher main body 5, be installed in the handrail 4 on the stretcher main body 5 and be used to support the supporting leg 2 of stretcher main body 5; Supporting leg 2 adopts the supporting leg that highly can regulate, and the bottom of each supporting leg 2 all is equipped with runner 1, and runner 1 is a Universal castor.Described supporting leg 2 comprises lower limb 21 and is installed in the following lower limb 22 that lower limb 21 inside can move up and down; Be fixed with positioner 7 in the bottom of last lower limb 21, have on the positioner 7 and hole that following lower limb 22 matches, following lower limb 22 passes hole on the positioner and packs into and go up lower limb 21 inside.Have a plurality of draw-in grooves 11 on the following lower limb 22 from top to bottom; Be set with ring-like brake(-holder) block 12 on the infra lower limb 22; Overlapping ring-like brake(-holder) block 12 just in time snaps in down in the draw-in groove 11 on the lower limb 22; Under the effect of positioner 7, this at present the height of lower limb 22 realized fixingly, overlap ring-like brake(-holder) block 12 in addition and pass positioner and be connected with DOCK LEVELER 8.Compression spring 9 is installed between cover ring-like brake(-holder) block 12 bottom surfaces and positioner 7.Hands is installed between supporting leg 2 and the stretcher main body 5 pinches receipts leg device 3, can supporting leg be packed up the below that lies in a horizontal plane in stretcher main body 5.In order to prevent down that lower limb 22 in use rotates, the location is exerted an influence, a side of infra lower limb 22 has stopper slot 10, and pin 6 is installed on last lower limb, and pin 6 passes lower limb and is stuck in the stopper slot 10.Can realize down that in pin 6 effect lower limb 22 moves up and down a fixed position down, the while has prevented that also time lower limb 22 from deviating from from last lower limb 21.
As shown in Figures 2 and 3; Hands is pinched receipts leg device 3 and is comprised the drive pinion 31 that is fixed on lower limb 21 upper ends, the transmission sector gear 32 that matches with drive pinion 31; Handle 33 is installed on the transmission sector gear 32; Transmission sector gear 32 is installed in the below of stretcher main body 5 through rotating shaft 34.Drive pinion 31 is fixed together with last lower limb 21 can realize the rotation of position in the same way; Transmission sector gear 32 is a pair of one group of gear with fixed drive ratio with drive pinion 31; The sector gear 32 of transmission simultaneously is an one with handle 33; Can under the effect of rotating shaft 34, rotate, realize lifting and putting down of supporting leg.Between last lower limb 21 and stretcher main body 5, be equipped with and reel bar 13, reel bar 13 and can realize that a supporting leg 2 is fixed on horizontal level, after handle 33 unclamps, still keep parallel, be used as stretcher to stretcher and lift enforcement usefulness with stretcher main body 5; If when stretcher uses, only need to reel bar 13 and opened in 2 minutes, make supporting leg 2 prop up stretcher main body 5 and get final product with supporting leg.The cross bar of stretcher main body 5 both sides is to be formed by two straight-bar hinges, when rescue finishes, can stretcher main body 5 be folded through hinge, and it is little that stretcher is taken up room, and is convenient for carrying.
Handrail 4 comprises 4 handrail connecting rods 41 that vertically are installed on the stretcher main body 5, and the bar 42 that can horizontally rotate is installed on the handrail connecting rod 41, and two rotary handrail support bars 43 respectively are installed on the both sides cross bar of stretcher main body 5.
Method for using: if in the open air or other place, when running into the ground out-of-flatness, when upwards lifting DOCK LEVELER 8 with instep slightly; Following lower limb 22 can be to lower slider in last lower limb 21; When being adjusted to required height, only need unclamp DOCK LEVELER 8, overlap 12 of ring-like brake(-holder) blocks and snap in down in the draw-in groove 11 on the lower limb 22; Under the effect of positioner 7, realized the fixing of time lower limb 22.Because each supporting leg 2 all adopts this device to regulate height, can be according to condition, the height of independent each supporting leg of adjustment, thus satisfy the demand of using.After rescue once finishes, under two people's operation, pack up supporting leg 2 easily through joystick, quick and convenient.
