[0006] However, in this patent, the adjustment of the width of the entire stretcher is achieved by extending and retracting the connecting tube and the connecting rod, but the stretcher canvas cannot be retracted or extended accordingly following the change in the width of the stretcher.

[0007] Therefore, there is an urgent need for an adjustable emergency stretcher to solve the above technical problems and to enable the size of the stretcher to be flexibly adjusted according to different rescue spaces. Utility Model Content

[0008] In view of the above technical problems, the utility model provides an adjustable stretcher for emergency use, which is used to solve the problem that the width of existing stretchers is fixed and the width cannot be flexibly adjusted according to the rescue space during the rescue process.

[0009] The above technical objectives of the utility model are achieved through the following technical solutions:

[0022] In summary, the beneficial technical effects of the utility model are:

[0023] (1) The telescopic sleeve and the telescopic rod are used to realize the relative movement of the first frame tube and the second frame tube, thereby changing the width of the entire stretcher. At the same time, the brake screw and the brake nut are used to fix the position after the width is adjusted. At the same time, the driving disk drives the first rolling rod to rotate to adjust the stretcher width to achieve real-time retraction and extension of the stretcher cloth, thereby avoiding the exposure of excess stretcher cloth to the outside when the stretcher width becomes smaller, thereby being able to flexibly respond to various rescue spaces during emergency treatment.

[0024] (2) By using the combination of the sleeve and the latch, the first rolling rod can be fixed after the width of the support cloth is adjusted, thereby preventing the support cloth from rotating along the first rolling rod when the patient is lifted.

[0025] (3) The bayonet can be used to fix the latch in the bayonet through the brake column when the first rolling rod rotates to collect the support cloth, so as to prevent the latch from being inserted into the fixing hole.

[0026] (4) The use of bearings can reduce the friction between the first and second reel rods during rotation, thereby reducing wear.

[0027] (5) The handle makes it easier for medical staff to apply force to the entire stretcher during rescue.

[0028] (6) By using universal wheels, when the stretcher is put into the ambulance, one end is attached to the ambulance and the stretcher can be pushed forward by the other end. At this time, the universal wheels make the movement easier and faster.

[0029] (7) A limit ring is used to limit the position of the support cloth wound on the first winding rod when it is being retracted and released, so as to prevent the winding from being misplaced and interfering with the cloth winding mouth. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] See attached Figure 1-4 , an adjustable stretcher for emergency use is shown, comprising a first frame tube 1 and a second frame tube 2 arranged in parallel, specifically, a rectangular cloth rolling opening 11 is opened on one side of the first frame tube 1 and the second frame tube 2 symmetrical to each other, the cloth rolling opening 11 is used for the passage of a cloth 3, and the cloth 3 is stored in the first frame tube 1 and the second frame tube 2 through the cloth rolling opening 11, wherein the first frame tube 1 is provided with a telescopic sleeve 6 at both ends close to the second frame tube 2, and the telescopic sleeve 6 is provided with a travel hole 8 along the length direction, and at the same time, the second frame tube 2 is provided with a telescopic rod 7 at a position corresponding to the telescopic sleeve 6, and the telescopic rod 7 can be inside the telescopic sleeve 6. Reciprocating sliding, at the same time, a brake screw 9 is provided at one end of the telescopic rod 7 close to the telescopic sleeve 6, the brake screw 9 is located in the stroke hole 8, and a brake nut 10 is provided on the brake screw 9. When in use, the telescopic sleeve 6 and the telescopic rod 7 move toward each other to achieve the first frame tube 1 and the second frame tube 2 to move closer to and away from each other, and the brake screw 9 and the brake nut 10 are used to achieve the relative fixation of the telescopic sleeve 6 and the telescopic rod 7, thereby realizing the adjustment of the width of the entire stretcher, adapting to more rescue spaces of different widths, reducing the labor intensity of medical staff during rescue, and making the rescue more efficient;

[0039] Bearings 12 are installed at both ends of the first frame tube 1 and the second frame tube 2. The first frame tube 1 and the second frame tube 2 are sleeved with a first rolling rod 4 and a second rolling rod 5 through the bearings 12. At the same time, a cloth support 3 for receiving a patient is wound on the first rolling rod 4. The other end of the cloth support 3 is connected to the second rolling rod 5 through a cloth rolling opening 11. When in use, the cloth support 3 is stored in the first frame tube 1 by the rotation of the first rolling rod 4. At the same time, a fixing disk 13 is provided at one end of the first frame tube 1. Twelve fixing holes 14 are provided in a circumferential array on the fixing disk 13. A driving disk 15 is provided at one end of the first rolling rod 4 located at the fixing disk 13. A driving handle is provided on the driving disk 15, wherein the driving handle includes a pipe sleeve 16 and a latch 17. A through hole is provided at the position of the pipe sleeve 16 of the driving disk 15. The latch 17 can be inserted into the fixing hole 14 through the through hole to achieve braking of the first rolling rod 4.

[0040] At the same time, travel grooves 18 are provided on both sides of the tube sleeve 16, and brake posts 19 are provided at positions of the latch 17 corresponding to the travel grooves 18. When the latch 17 is inserted into the fixing hole 14, the brake posts 19 just slide in the travel grooves 18;

[0041] At the same time, the ends of the other two sides of the tube sleeve 16 are provided with bayonet holes 20. When the first rolling rod 4 is driven to rotate by the driving handle, the latch 17 can be pulled out from the fixing hole 14 and the brake column 19 can be clamped into the bayonet holes 20.

When the patient is transferred from the stretcher to the ambulance, one end of the stretcher can be attached to the ambulance, and then the other end of the stretcher is pushed forward, and the stretcher can be easily put into the ambulance with the help of the universal wheels 21;

[0043] At the same time, in order to provide a limiting effect on the support cloth 3 when it is retracted and released, a limiting stop ring 24 is fixed at both ends of the first rolling rod 4 and the second rolling rod 5. The two limiting stop rings 24 limit the support cloth 3 between the two to prevent deviation during retraction and release.

[0044] At the same time, in order to facilitate the rotation of the brake nut 10 , a brake handle 23 is provided on the brake nut 10 , and force can be conveniently applied to the brake nut 10 through the brake handle 23 .

[0045] When in use, when the width of the entire stretcher needs to be increased, the brake nut 10 is first loosened by the brake handle 23, and then the first frame tube 1 and the second frame tube 2 are pulled apart from each other by the handle 22. During the process of the first frame tube 1 and the second frame tube 2 being separated from each other, the telescopic rod 7 slides outward along the telescopic sleeve 6, and at the same time, the first rolling rod 4 is driven to rotate and release the cloth 3. When the preset width is reached, the brake nut 10 is used to relatively fix the telescopic sleeve 6 and the telescopic rod 7, and then the latch 17 is inserted into the fixing hole 14 to brake the first rolling rod 4.

[0046] When the width of the stretcher needs to be reduced, the brake nut 10 is loosened by the brake handle 23, and then the driving handle is used to drive the driving disk 15 to rotate, and the driving disk 15 further drives the first rolling rod 4 to rotate and wind the support cloth 3 to be stored in the first frame tube 1, and then the brake nut 10 is used to complete the fixation of the telescopic sleeve 6 and the telescopic rod 7, and finally the pin 17 is inserted into the fixing hole 14.
