Description

Technical Field

[0001] The utility model relates to the technical field of portable stretchers, in particular to a portable stretcher which can be quickly unfolded and used. Background Art

[0002] Stretchers are often used as tools to rescue and transfer the wounded. Portable stretchers are mostly used on the battlefield. Multiple sets of connecting rods and supporting fabrics are connected by buckles and hinges. The shovel stretcher is composed of two left and right aluminum alloy plates. When transporting the wounded, first place the wounded in a supine position and fix the neck. Then, the left and right pieces of the stretcher are inserted into the back from the sides of the wounded, and then buckled before transporting.

[0003] According to a portable N-type folding field stretcher and a suspended cascade combined stretcher set with publication number CN219963278U. The utility model provides a portable N-type folding field stretcher, which is used for a suspended cascade combined stretcher carrier frame. The suspended cascade combined stretcher carrier frame is provided with a support leg socket. The portable N-type folding field stretcher comprises: a stretcher body, the stretcher body comprises a stretcher support leg, a stretcher bed cloth and two N-type folding stretcher rods arranged opposite to each other, the stretcher bed cloth is connected to the two N-type folding stretcher rods and is located between the two N-type folding stretcher rods; the N-type folding stretcher rod comprises three sections of stretcher lifting rods arranged in sequence along the extension direction, and two adjacent stretcher lifting rods are rotatably connected by a connecting structure; stretcher lifting rods at both ends are provided with stretcher support legs, and the stretcher support legs are used to be inserted in the support leg socket, and the connecting structure comprises at least one connecting block arranged at the end of one stretcher lifting rod and a connecting seat arranged at the end of the other stretcher lifting rod; the connecting seat is provided with a shaft and a limiting groove corresponding to the connecting block, the shaft is rotatably connected to one end of the connecting block, and the other end of the connecting block can enter and exit the limiting groove by rotating. When two adjacent stretcher lifting rods are relatively unfolded in a straight line, the connection block is located in the limiting groove; when the two adjacent stretcher lifting rods are relatively folded, one end of the connection block rotates with the shaft and the other end extends out of the limiting groove. The connection structure forms a hinge-type twisted connection.

[0004] The above patent mentions that when two adjacent stretcher lifting rods are folded relative to each other, one end of the connecting block rotates with the shaft, and the other end extends out of the limit groove connecting structure to form a hinge-type twisted connection. The N-type folding field stretcher can be folded and stored in an N shape. However, since the stretcher bed cloth is connected to the two N-type folding stretcher rods and is located between the two N-type folding stretcher rods, after the N-type folding field stretcher is folded, the stretcher bed cloth and the N-type folding stretcher rods are in a separated state, so that when the N-type folding field stretcher is in use, the stretcher bed cloth needs to be connected to the N-type folding stretcher rods, which makes it impossible to put the N-type folding field stretcher into use quickly, and it is inconvenient to use. Utility Model Content

[0005] The utility model aims to provide a portable stretcher that can be quickly unfolded for use, so as to solve the problem that the stretchers currently on the market need to connect the stretcher bed cloth with the N-shaped folding stretcher rod when in use, as mentioned in the background art.

[0007] Preferably, the inner sides of both ends of the two groups of support rods are connected to hinges extending to the inner side of the connecting rod through a rotating shaft, and the hinges are connected to the inner side of the connecting rod through the rotating shaft, and the outer walls of one end of the four groups of connecting rods are all provided with anti-slip handles.

[0008] Preferably, the inner wall of the anti-slip handle is threadedly connected to the outer wall of the connecting rod.

[0009] Preferably, a supporting fabric is arranged between the two groups of connecting sleeves, a connecting belt is sewn on the bottom end of one group of connecting sleeves, and a Velcro hook belt is arranged on the top end of the connecting belt.

[0010] Preferably, a first Velcro strap is provided at the bottom end of the connecting belt, and a second Velcro strap is provided at the bottom end of the supporting fabric.

[0011] Preferably, the Velcro hook surface tape is adhesively connected to the first Velcro fleece surface tape, and the Velcro hook surface tape is adhesively connected to the second Velcro fleece surface tape.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the portable stretcher needs to be used, the Velcro hook surface band is separated from the first Velcro fleece surface band, and the connecting band is untied from the outer wall of the stretcher, and the four groups of connecting rods are rotated upward with the hinge as the axis, and the connecting rod drives the hinge to rotate through the rotating shaft, and the hinge supports the support rod and the connecting rod, and the supporting cloth is unfolded through the anti-slip handle, the connecting rod, the hinge, the support rod and the connecting sleeve, and the wounded is placed on the supporting cloth of the stretcher to transfer the wounded. By directly unfolding the portable stretcher for use, the assembly efficiency of the stretcher is effectively improved, the stretcher is easy to be put into use quickly, and convenience is provided for the user.

[0014] 2. When the connecting sleeve on the portable stretcher needs to be cleaned, the anti-slip handle at one end of the connecting rod is spirally separated from the connecting rod, and the connecting sleeve is pulled out from the outer wall of the supporting rod and the connecting rod, so that the connecting sleeve is separated from the supporting rod and the connecting rod, making it easy to clean and replace the supporting fabric, thereby effectively extending the service life of the portable stretcher.
