According to the rotary foldable stretcher, M-type stretching folding of a stretcher can be achieved. The rotary foldable stretcher is safe and reliable, fast in stretching and retracting, small in volume, and light in weight.
Description
Technical field
This utility model relates to a kind of Folding stretcher, particularly a kind of rotary type folding stretcher.
Background technology
Stretcher is a kind of important wounded's handbarrow, is mainly used in the transfer of injury personnel's in flat wartime short distance carrying and various health means of transports or takes.Generally by range of application it is divided into General stretcher and special stretcher two classes.Wherein, Folding stretcher is a kind of General stretcher, can adopt two foldings, three-bend or four-folding structure, and folding mode is generally also adopted in stull, is made of parts such as stretcher rod, handle, supporting leg, stretcher face, horizontal support and wounded's fixing bands.Also can be equipped with as required corresponding adnexa, such as drip stand, medicated pillow and packaging bag etc.Traditional folding stretcher makes easily the sick and wounded overturn and topples because can only unidirectional-folding, causes secondary damage.
The utility model content
This utility model both can satisfy folding requirement, the rotary type folding stretcher that can not make the sick and wounded overturn and topple again for the technical problem that exists in the solution known technology provides a kind of.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is: a kind of rotary type folding stretcher, two stretcher rods about comprising, between two described stretcher rods, be provided with the horizontal support of twice, be fixed with the soft stretcher pad in described horizontal support and described stretcher rod, end at described stretcher rod is provided with handle, the bottom is provided with supporting leg, the described horizontal support of per pass comprises the section of parting on the left side and the section of parting on the right side that connects by connecting plate, the inner of the described section of parting on the right side is respectively hinged by a vertical bearing pin and described connecting plate with the inner of the described section of parting on the left side, and the outer end of the described section of parting on the right side is respectively hinged by the described stretcher rod of a vertical bearing pin and respective side with the outer end of the described section of parting on the left side; Every described stretcher rod comprises four segmentations that set gradually, the first segmentation and the second segmentation are by the first stretcher rod chain connection, the second segmentation and the 3rd segmentation are by the second stretcher rod chain connection, the 3rd segmentation and the 4th segmentation are by the 3rd stretcher rod chain connection, described the first stretcher rod hinge is identical with the structure of described the 3rd stretcher rod hinge, be counterrotating castellated structure downwards, described the second stretcher rod hinge is the counterrotating castellated structure that makes progress.
Described supporting leg is connected with described stretcher rod by the supporting leg hinge, and described supporting leg hinge is the castellated structure of inwardly rotating.
Described Air cushion used on stretcher adopts sorptive material to make.
The transverse section of described stretcher rod is square structure or circular configuration.
The advantage that the utlity model has with good effect is: by at horizontal support middle part vertical bearing pin being set, and it is connected by vertical bearing pin with stretcher rod, simultaneously, at stretcher rod castellated hinge is set, and make the adjacent hinge rotation direction opposite, realized the M shape unfolded of stretcher, safe and reliable, exhibition is received fast, volume is little, lightweight, widely dual-use DEVELOPMENT PROSPECT is arranged, especially be fit to pre hospital care and First aid station and use.Compare price low about 25% with external traditional unidirectional-folding stretcher.
