The purpose of this utility model is achieved through the following technical solutions:

Compared with prior art, this utility model technology has the following advantages: a kind of folding Backpack type stretcher, comprise two montants that be arranged in parallel and be connected in the first cross bar between two montants, be provided with stretcher cloth between described two montants, it is characterized in that: also comprise two braces, two connecting rods, two supporting legs and two seat bar, described two connecting rods, two supporting legs, two seat bar and two montants consist of respectively two can make connecting rod, supporting leg, seat bar is drawn close folding four-bar linkage to montant, this four-bar linkage is: an end of described connecting rod and the middle part of seat bar are articulated in respectively the middle part of montant, the other end of described connecting rod is articulated in an end of supporting leg, and described support midleg is articulated in an end of seat bar; Be provided with seat cloth between described two seat bar; Described two braces are connected between montant and the supporting leg.

When four-bar linkage launched, montant, connecting rod, supporting leg, seat bar consisted of seat, and this moment, the wounded can sit on the seat, by the transhipment of the single shoulder back of the body; Also can realize that two people lift altogether by two montants.

On the basis of the above, this utility model can be done following improvement:

Be connected with the second cross bar between two supporting legs described in the utility model, be connected with the 3rd cross bar between described two seat bar; But the first to the 3rd cross bar is the folding rod member of doubling.

The folding direction of the first cross bar described in the utility model and two montants plane parallel of living in, the folding direction of the second cross bar and two supporting legs plane parallel of living in, the folding direction of the 3rd cross bar and two seat bar plane parallel of living in.

The both ends of montant described in the utility model are equipped with for the extension rod that lengthens montant length, and this extension rod and montant are slidingly connected, so that two people lift altogether.

Montant described in the utility model is the hollow stem of both ends open, and described extension rod is plugged in the montant.

Folding Backpack type stretcher described in the utility model also comprises seat belt, is connected between two montants.

Supporting leg described in the utility model is folding rod member.

The folding direction of supporting leg described in the utility model is vertical with described four-bar linkage plane of living in.

Compared with prior art, this utility model technology has following advantage:

This utility model stretcher adaptable, can single shoulder unluckyly turn the wounded, be adapted at the safety transhipment wounded under ground injustice, narrow space (such as high building corridor, stair, elevator, open-air tipping bucket hill path), the undermanned condition, also can doublely lift altogether the transhipment wounded, fast and easy is specially adapted to rugged hill path, also can be by folding of the first to the 3rd cross bar and folding of supporting leg, can reduce the volume of whole stretcher after folding, easy to carry and store.
