[0001] This utility model relates to the field of stretchers, and in particular to a multi-purpose roll-up stretcher. Background Technology
[0002] Roll-up stretchers are a type of lightweight and portable stretcher widely used in various occasions such as medical emergency, disaster relief, sports events, outdoor activities, and military rescue. Roll-up stretchers can be rolled up in a roller or backpack for carrying, taking up little space and being lightweight, and have multiple uses in various situations.
[0003] When using a roll-up stretcher, unfold the stretcher body, then pass the straps through the through holes on both sides to secure the injured person before using the roll-up stretcher. When dragging the stretcher body on an uneven surface, the bottom of the stretcher body is in direct contact with the ground, resulting in high friction between the stretcher body and the ground. This requires more force to drag, which can affect the effectiveness of using the stretcher body. Utility Model Content
[0004] The technical problem this utility model aims to solve is that when the stretcher body is dragged on an uneven surface, the bottom of the stretcher body directly contacts the ground, resulting in greater friction between the stretcher body and the ground. This requires more force to drag, which in turn affects the effectiveness of the stretcher body.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a multi-purpose roll-up stretcher, including a stretcher body, a plurality of through holes on one side of the stretcher body, straps provided at the plurality of through holes on one side of the stretcher body, a moving device provided at the bottom of the stretcher body, the moving device including a placement block, one side of the placement block being fixedly connected to the stretcher body, a bolt being threaded into one side of the placement block, a connecting plate being threaded to one side of the bolt, a U-shaped block being fixedly connected to one side of the connecting plate, a round rod being rotatably connected to one side of the U-shaped block, and a roller being fixedly connected to one side of the round rod.
[0006] The aforementioned components achieve the following effects: When using a roll-up stretcher, the stretcher body is unfolded, and the straps are passed through the through holes on both sides to secure the injured person before use. When it is necessary to drag the stretcher body on the ground, the U-shaped block can be moved so that the connecting plate on one side of the U-shaped block is inserted into the placement block. Then, the bolt is turned so that it passes through the placement block and is fixed to the connecting plate. When the stretcher body is dragged, the roller drives the round rod to rotate on the U-shaped block, thus moving the stretcher body on the ground. By using the moving device, rollers can be fixed at the bottom of the stretcher body, allowing the stretcher body to be dragged quickly on uneven surfaces, avoiding excessive friction between the stretcher body and the ground, which would otherwise require a lot of force to drag, thereby improving the effectiveness of the stretcher body.
[0007] Preferably, one side of the bolt abuts against a washer, and one side of the washer abuts against the placement block.
[0008] The effect achieved by the above components is to increase the contact area between the bolt and the placement block by using shims, so that the bolt can more firmly fix the connecting plate.
[0009] Preferably, an operating block is fixedly connected to one side of the bolt, and the size of the operating block is adapted to the size of the bolt.
[0010] The effect achieved by the above components is to increase the contact area between the bolt and the operator by using the operating block, making the bolt easier to rotate.
[0011] Preferably, bearings are fixedly connected to both sides of the round rod, and the outer ring of the bearing is fixedly connected to the U-shaped block.
[0012] The effect achieved by the above components is to reduce the friction between the round rod and the U-shaped block by using bearings, making the roller roll more easily, thereby improving the performance of the roller.
[0013] Preferably, a plurality of anti-slip blocks are fixedly connected to both sides of the U-shaped block, and the plurality of anti-slip blocks are arranged at equal intervals on both sides of the U-shaped block.
[0014] The effect achieved by the above components is to increase the friction between the operator and the U-shaped block by using anti-slip blocks, making it easier for the operator to move the U-shaped block.

A hook and loop fastener is fixedly connected to one side of the stretcher body, and a loop fastener is fixedly connected to one side of the stretcher body.
[0016] The aforementioned components achieve the following effects: When the auxiliary strap is not in use, it is moved to the side where the hook and loop sides of the Velcro are close to each other, and then the hook and loop sides are glued together to secure the auxiliary strap. When the stretcher body is pulled, the auxiliary strap can be removed to increase the contact area between the operator and the stretcher body, assisting the operator in dragging the stretcher body. By using the auxiliary components, it is easier for the operator to drag the stretcher body, thereby improving the usability of the stretcher body.
[0017] Preferably, a reinforcing block is fixedly connected to one side of the Velcro hook, and one side of the reinforcing block is fixedly connected to the stretcher body.

[0031] Figures 1 to 4 The multi-purpose roll-up stretcher shown includes a stretcher body 1, a number of through holes 4 on one side of the stretcher body 1, straps 5 at the number of through holes 4 on one side of the stretcher body 1, and a moving device 2 at the bottom of the stretcher body 1.
[0032] Figures 1 to 4The movable device 2 shown includes a placement block 21. One side of the placement block 21 is fixedly connected to the stretcher body 1. A bolt 22 is threaded into one side of the placement block 21. A connecting plate 23 is threaded to one side of the bolt 22. A U-shaped block 24 is fixedly connected to one side of the connecting plate 23. A round rod 25 is rotatably connected to one side of the U-shaped block 24. A roller 26 is fixedly connected to one side of the round rod 25. When using the roll-up stretcher, the stretcher body 1 is unfolded, and then the straps 5 are passed through the through holes 4 on both sides to fix the injured person before using the roll-up stretcher. When the stretcher body 1 needs to be dragged on the ground, the U-shaped block 24 can be moved so that the connecting plate 23 on one side of the U-shaped block 24 can be inserted into the placement block 21. Then, the bolt 22 can be rotated so that the bolt 22 passes through the placement block 21 and is fixed to the connecting plate 23. When the stretcher body 1 is dragged, the roller 26 drives the round rod 25 to rotate on the U-shaped block 24, thus moving the stretcher body 1 on the ground. By using the moving device 2, the roller 26 can be fixed at the bottom of the stretcher body 1, so that the stretcher body 1 can be dragged quickly on the uneven ground, avoiding the large friction between the stretcher body 1 and the ground, which would otherwise require a lot of force to drag, thereby improving the use effect of the stretcher body 1.
[0033] Figures 1 to 4 One side of the bolt 22 is abutted against a washer 27, and one side of the washer 27 abuts against a placement block 21. By using the washer 27, the contact area between the bolt 22 and the placement block 21 is increased, making the bolt 22 more securely fixed to the connecting plate 23. An operating block 28 is fixedly connected to one side of the bolt 22, and the size of the operating block 28 is adapted to the size of the bolt 22. By using the operating block 28, the contact area between the bolt 22 and the operator is increased, making the bolt 22 easier to rotate. Bearings 29 are fixedly connected to both sides of the round rod 25, and the outer ring of the bearing 29 is fixedly connected to the U-shaped block 24. By using the bearings 29, the friction between the round rod 25 and the U-shaped block 24 is reduced, making the roller 26 roll more easily, thereby improving the performance of the roller 26. Several anti-slip blocks 210 are fixedly connected to both sides of the U-shaped block 24, and the anti-slip blocks 210 are arranged equidistantly on both sides of the U-shaped block 24. By using the anti-slip block 210, the friction between the operator and the U-shaped block 24 is increased, making it easier for the operator to move the U-shaped block 24.
[0034] Figures 1 to 4The stretcher body 1 shown has an auxiliary component 3 on one side. The auxiliary component 3 includes an auxiliary strap 31, which is fixedly connected to the stretcher body 1. A hook and loop fastener 32 and a loop fastener 33 are fixedly connected to one side of the stretcher body 1. When the auxiliary strap 31 is not in use, it is moved to the side where the hook and loop fastener 32 and the loop fastener 33 are close to each other, and then the hook and loop fastener 32 and the loop fastener 33 are glued together to fix the auxiliary strap 31. When the stretcher body 1 is pulled, the auxiliary strap 31 can be removed to increase the contact area between the operator and the stretcher body 1, assisting the operator in dragging the stretcher body. By using the auxiliary component 3, it is easier for the operator to drag the stretcher body 1, thereby improving the usability of the stretcher body 1.
[0035] Figures 1 to 4 A reinforcing block 34 is fixedly connected to one side of the Velcro hook face 32, and one side of the reinforcing block 34 is fixedly connected to the stretcher body 1. The reinforcing block 34 enhances the connection strength between the stretcher body 1 and the reinforcing block 34, preventing the Velcro hook face 32 and the stretcher body 1 from separating under force. A rubber sleeve 35 is fixedly connected to one side of the auxiliary strap 31, and the size of the rubber sleeve 35 is adapted to the size of the auxiliary strap 31. The rubber sleeve 35 increases the friction between the auxiliary strap 31 and the operator, allowing the operator to grip the auxiliary strap 31 more firmly for use.
[0036] Working principle: When using the roll-up stretcher, unfold the stretcher body 1, then pass the straps 5 through the through holes 4 on both sides to secure the injured person, and then use the roll-up stretcher. When it is necessary to drag the stretcher body 1 on the ground, the U-shaped block 24 can be moved so that the connecting plate 23 on one side of the U-shaped block 24 is inserted into the placement block 21. Then, by operating the block 28, the bolt 22 is rotated so that the bolt 22 passes through the placement block 21 and is fixed to the connecting plate 23. When the stretcher body 1 is dragged, the roller 26 drives the round rod 25 with the bearing 29 to rotate on the U-shaped block 24, thus moving the stretcher body 1 on the ground. By using the moving device 2, the roller 26 can be fixed at the bottom of the stretcher body 1, so that the stretcher body 1 can be dragged quickly on uneven ground, avoiding excessive friction between the stretcher body 1 and the ground, which would otherwise require a lot of force to drag, thereby improving the use of the stretcher body 1.
[0037] When the auxiliary strap 31 is not in use, move the auxiliary strap 31 to the side where the hook and loop sides 32 and 33 are close to each other, and then stick the hook and loop sides 32 and 33 together to fix the auxiliary strap 31. When pulling the stretcher body 1, the auxiliary strap 31 with the rubber sleeve 35 can be removed to increase the contact area between the operator and the stretcher body 1, and assist the operator in dragging the stretcher body. By using the auxiliary component 3, it is easier for the operator to drag the stretcher body 1, thereby improving the use effect of the stretcher body 1.
[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
