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.

The specific embodiment
Below in conjunction with specific embodiment this utility model is further set forth.
Such as Fig. 1-a kind of folding Backpack type stretcher shown in Figure 4, comprise two montants that be arranged in parallel 1, be connected in the first cross bar 2, two braces 3, two connecting rods 4, two supporting legs 5 and two seat bar 6 between two montants 1, this stretcher integral body is symmetrical structure.Be provided with stretcher cloth 7 between two montants 1, two connecting rods 4, two supporting legs 5, two seat bar 6 and two montants 1 consist of respectively two can make connecting rod 4, supporting leg 5, seat bar 6 draw close folding four-bar linkage to montant 1, this four-bar linkage is: an end of connecting rod 4 and the middle part of seat bar 6 are articulated in respectively the middle part of montant 1, the other end of connecting rod 4 is articulated in an end of supporting leg 5, and the middle part of supporting leg 5 is articulated in an end of seat bar 6; Be provided with seat cloth 8 between two seat bar 6; Two braces 3 are connected between montant 1 and the supporting leg 5.Wherein, montant 1, the first cross bar 2, supporting leg 5 all can adopt aluminum alloy materials to make, and connecting rod 4 is a connection steel disc.
Be connected with between two supporting legs 5 between the second cross bar 9, two seat bar 6 and be connected with the 3rd cross bar 10; But the first to the 3rd cross bar is the folding rod member of doubling.The folding direction of the first cross bar 2 and two montants, 1 plane parallel of living in, the folding direction of the second cross bar 9 and two supporting legs, 5 plane parallel of living in, the folding direction of the 3rd cross bar 10 and two seat bar, 6 plane parallel of living in; After four-bar linkage was folding, the first to the 3rd cross bar was all only folding in the same direction.Second, third cross bar is two, and the end that two second cross bars 9 are connected to two seat bar 6 forms seat frame.Supporting leg 5 also is folding rod member, and the folding direction of supporting leg 5 is vertical with four-bar linkage plane of living in.
The both ends of montant 1 are equipped with for the extension rod 11 that lengthens montant length, and montant 1 is the hollow stem of both ends open, and this extension rod 11 is plugged in perpendicular 1 bar, is slidingly connected with montant 1.One rod end of extension rod 11 also is provided with the handle of being convenient to grasp, and is beneficial to staff for increasing friction and lifts safely stretcher, and extension rod 11 another rod ends have the bent handle of being convenient to pull out extension rod 11.Also be connected with seat belt 12 between two montants 1, be used for the constraint wounded, shield.
When the transhipment narrow space, as shown in Figure 1, deployable four-bar linkage, montant 1, connecting rod 4, supporting leg 5, seat bar 6 consist of seats at this moment, and the wounded can sit on the seat, fasten seat belt 12 again, by the transhipment of the single shoulder back of the body; Enough and personnel are sufficient when needing rapid transport again or when running into rugged mountain path when the transhipment space, such as Fig. 2-shown in Figure 3, can pull out extension rod 11, can directly will sit fast the wounded that form on the seat sitting posture and be lifted by two people this moment, the wounded still can keep the downward comfort conditions of foot on rugged hill path, fasten again seat belt 12 and guarantee safety, also can shed braces this moment and be convenient to transportation; Do not use this stretcher or carry when mobile, as shown in Figure 4, also can by the first to the 3rd cross bar, supporting leg fold dwindle the stretcher volume, easy to carry and store.
Embodiment of the present utility model is not limited to this, according to foregoing, ordinary skill knowledge and customary means according to this area, do not breaking away under the above-mentioned basic fundamental thought of this utility model prerequisite, equivalent modifications, replacement or change that this utility model can also be made other various ways all can realize this utility model purpose.
