TECHNICAL FIELD
[0001] The utility model relates to the field of rescue transportation, in particular to a foldable rescue stretcher. BACKGROUND
[0002] In the rescue situation, most of the traditional rescue stretcher is large in size and fixed in structure, which is difficult to effectively store. In the transportation process, it often needs to occupy a large space, whether it is transported by vehicle or carried by manpower, which is relatively inconvenient. For example, some large metal frame stretchers, the size is usually about two meters, and the width is also relatively wide, which will occupy a lot of space in the rescue vehicle and affect the loading of other rescue equipment.
[0003] The stretcher in the prior art cannot be disassembled, so that when high-temperature disinfection is needed, the whole stretcher needs to be directly put into a high-temperature box for sterilization and disinfection. However, long-term reciprocating will cause the stretcher support rod structure to be damaged due to thermal expansion and contraction at high temperature, and the stretcher structure is easy to be corroded and damaged by contacting with cleaning agent at high temperature.
[0004] The existing telescopic rod type stretcher is easy to break due to the hollow structure of the folding rod, and it is not easy to carry patients with heavy weight. After the existing stretcher is carried, the stretcher rod is not easy to disassemble when the patient is bleeding, or the fixed structure of the stretcher rod leads to the stretcher not easy to clean. The stretcher needs to be disassembled repeatedly, which wastes time and energy, and the disassembly is easy to damage the original structure of the stretcher. Once the stretcher is contaminated by blood stains and infectious agents, the cleanliness of the stretcher will be reduced, and even the use of the stretcher will be affected. Therefore, it is urgent to develop a stretcher with large carrying capacity, easy to carry and easy to disassemble and clean. UTILITY MODEL CONTENTS
[0005] The utility model solves the technical problem that the stretcher cloth is not easy to clean after being contaminated. The problem that the existing telescopic rod is easy to break is solved.
[0006] In order to solve the above problems, the present application is realized by the following technical scheme:
[0007] A foldable rescue stretcher, comprising a plurality of stretcher rods, each of the stretcher rods is fixedly connected with a first clamping block and a second clamping block at the bottom of the symmetrical two ends, and the same side of the first clamping block and the second clamping block is provided with a fixed hole,
[0008] Each stretcher rod is slidably connected with a first folding rod at one end through a fixed shaft, and each stretcher rod is slidably connected with a second folding rod at the other end through a fixed shaft.
[0009] The first folding rod is fixedly provided with a third clamping block at one end, and the third clamping block is provided with a fixed hole at one end; the fixed hole of the third clamping block is installed between the fixed holes of the first clamping block and the second clamping block in alignment, and the inner wall of the fixed hole of the third clamping block and the inner wall of the fixed hole of the first clamping block and the second clamping block are slidably fixedly connected with the outer wall of the fixed shaft.
[0010] The bottom of the fixed shaft is spirally fixedly connected with the side wall of the nut.
[0011] The first folding rod is provided with a handle.
[0012] The third nylon cloth is sleeved between the side walls of every two stretcher rods.
[0013] The second nylon cloth is sleeved between the side walls of every two second folding rods, and spandex cotton cloth is fixedly sewn between the second nylon cloth and the third nylon cloth.
[0014] The first nylon cloth is sleeved between the side walls of every two first folding rods, the cloth tube is sleeved with the first folding rod, the zipper is arranged at the bottom of each cloth tube, and a plurality of chain teeth on the chains on the two sides of the zipper are locked and buckled with each other through the zipper lock, and spandex cotton cloth is fixedly sewn between the first nylon cloth and the third nylon cloth.
[0015] The bottom of the two ends of each stretcher rod is further provided with a buffer groove, and the buffer groove is in contact with the buffer column.
[0016] The inner side of the first folding rod groove is fixedly connected with the buffer column.
[0017] The stretcher rod is two in total.
[0018] Preferably, the first nylon cloth and the second nylon cloth are completely same.
[0019] Preferably, the first folding rod and the second folding rod are completely same.
[0020] Compared with the prior art, the utility model has the beneficial effects of:
[0021] 1. The foldable rescue stretcher is convenient to fold and store and does not occupy space, can be placed in a small storage cabinet and is ready for use at any time. The stretcher will not be scattered, ensuring the safety and convenience of carrying. The portable stretcher overcomes the disadvantage that the traditional stretcher is large in size and not easy to carry, and is more convenient to transport during rescue. The foldable rescue stretcher is small in size and does not occupy too much space.
[0022] 2. By arranging the zipper on the first nylon cloth, the second nylon cloth and the third nylon cloth, after carrying the patient, the nylon cloth can be directly removed by the zipper when cleaning the contaminated nylon cloth. After cleaning, it is very convenient to install it again. BRIEF DESCRIPTION OF DRAWINGS
