Problems solved by technology

[0002] At present, in the rescue and transport of the wounded, the stretcher is an indispensable transport tool, especially after the earthquake and other disasters, the role of the stretcher in use is becoming more and more important, and the requirements for the stretcher are also getting higher and higher. Now known stretchers all place the wounded and sick on the stretcher, and the inclination angle of the stretcher is constantly changing with the change of the height of the road under the feet. If the position is no longer kept level, it may cause undue secondary injuries such as nerve compression and cerebral congestion to the body of the wounded and sick
Therefore existing stretchers run into places with slopes in emergency rescue, such as stairs, hillsides or in the process of crossing obstacles and crossing rivers. The horizontal posture occupies a large number of people, and it is very inconvenient to use, and it is also difficult to make the body of the wounded and sick reach a horizontal posture when using it

Embodiment 1

[0024] Embodiment 1: with reference to attached Figure 1~4 , is a structural schematic diagram of Embodiment 1 of the present invention, including an outer frame 1 and an inner frame 3, the outer frame 1 is composed of an outer frame straight beam 103 and an outer frame crossbeam to form a rectangular frame-shaped body, and the longitudinal ends of the rectangular frame-shaped body A stretcher handle 101 is provided, and the outer frame beam is composed of a pair of telescopic outer sleeve 102 and an inner tube 105, and a sleeve locking mechanism is arranged between the outer sleeve 102 and the inner tube 105, and the sleeve locking mechanism is a pin . The inner frame 3 is composed of two inner frame straight beams 301 and several inner frame beams 302 to form a rectangular grid-shaped bed body, and the inner frame 3 is arranged on the inner side of the outer frame 1 . The middle parts of the outer frame 1 and the inner frame 3 are hinged to each other: the inner sides of t...

Embodiment 2

[0025] Embodiment 2: with reference to attached Figure 5 , is a structural schematic diagram of the horizontal adjustment mechanism in Embodiment 2 of the present invention. Compared with Embodiment 1, the difference of this embodiment is that the bushing is divided into two sections, one of which is connected to the crank rod 204 described above, The other section is connected to the inner frame straight beam 301 of the inner frame 3, and the two sections of bushes are engaged in a slit shape and can be separated.

Embodiment 3

[0026] Embodiment 3: with reference to attached Figure 6~Figure 7 , is a schematic structural diagram of the sleeve locking mechanism in Embodiment 3 of the present invention. Compared with Embodiment 1, the difference of this embodiment is that the sleeve locking mechanism has the following structure: a slot is provided on the outer sleeve 102, and The inner tube 105 is provided with a "V"-shaped hook 108, the upper end of the "V"-shaped hook 108 is provided with a return spring 109 and the upper end of the "V"-shaped hook 108 can be stuck in the slot of the outer sleeve 102 Among them, the lower part of the "V"-shaped hook 108 is hinged with each other and the inner side is provided with a pull wire 107. There is no switch button 106 on the stretcher handle 101. The switch button 106 is connected to the pull wire 107 and pulls the pull wire 107, thereby making the "V" The upper end of the shaped hook 108 shrinks inward and withdraws from the said slot.

Abstract

The invention discloses an automatic leveling stretcher which comprises an outer frame (1) and an inner frame (3), wherein the middle parts of the outer frame (1) and the inner frame (3) are hinged with each other, and a leveling mechanism (2) is arranged between the outer frame (1) and the inner frame (3). Compared with the prior art, the inclination angle of the stretcher body can be changed through the linkage of the arms of people carrying the stretcher, and thus, the automatic leveling stretcher is simple to operate and saves the labor; the automatic leveling of the stretcher body can bemaintained when people are tramping over the hill and dale and going across the river; the automatic leveling stretcher is convenient and practical; and since the inner frame and the outer frame of the stretcher can be separated, the wounded person can be always fixed on the inner frame, and the outer frame can be removed, thereby preventing the wounded person from secondary injury in the salvageand rescue process.
