[0001] This utility model relates to the field of fire rescue stretchers, specifically a multi-functional rescue stretcher for fire rescue. Background Technology
[0002] Firefighting and rescue are key forces in ensuring public safety and responding to fires and other emergencies. Their core responsibilities are to prevent fires, reduce losses, and protect lives and property. Firefighting and rescue stretchers are key equipment used to transfer the wounded in firefighting and emergency rescue scenarios. Their design must take into account portability, durability, multi-functionality, and the ability to adapt to complex environments.
[0003] However, most existing fire rescue stretchers have simple structures and single functions, and the main body cannot be folded. This makes them large and heavy, making it difficult to pass through narrow passages (such as stairs, elevators, and gaps in rubble) or to be quickly loaded into rescue vehicles (such as helicopters and ambulances). Furthermore, non-folding stretchers require multiple people to carry them, and are difficult to operate in complex terrain (such as mountains and swamps), which can easily lead to fatigue or injury of rescue personnel. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0024] This application discloses a multi-functional rescue stretcher for fire and rescue operations. (Refer to...) Figures 1 to 5A multi-functional rescue stretcher for fire and rescue includes a first support plate 1, a rotating component 2 fixedly connected to one side of the first support plate 1, and a second support plate 3 fixedly connected to one side of the rotating component 2. Both the first support plate 1 and the second support plate 3 have a first through groove 4 on one side. A multi-functional fixing strap 5 is fixedly connected to one side of the first support plate 1. A leg support assembly 6 is provided in the inner cavity of the second support plate 3. The first support plate 1 and the second support plate 3 are connected via the rotating component 2, which mainly serves to connect and assist in the flipping and folding of the first and second support plates 1 and 3. When unfolded, the first and second support plates 1 and 3 form the main body of the stretcher, allowing the injured to be transferred for transport. The multi-functional fixing strap 5 can be used as a carrying strap when the first and second support plates 1 and 3 are folded and stored, allowing rescuers to carry the stretcher on their backs and free their hands. When unfolded, the multi-functional fixing strap 5 can be used as a fixing strap to secure the injured person's shoulders, ensuring stability during transfer.
[0025] Reference Figure 3 and Figure 4 One side of each of the first support plate 1 and the second support plate 3 is fixedly connected to an extension plate 7. Each side of the extension plate 7 has a fixing groove 8. A connecting rod 9 is inserted into the inner wall of the fixing groove 8. One end of the connecting rod 9 is fixedly connected to a stop block 10. A blocking member 17 is threaded onto the surface of the connecting rod 9. One side of the blocking member 17 abuts against one side of the extension plate 7. The outer dimensions of the blocking member 17 are equal to the inner wall dimensions of the fixing groove 8. Through the extension plate 7, when the first support plate 1 and the second support plate 3 are folded together, the extension plate 7 and the fixing groove 8 are aligned. The fixed slots 8 are interconnected. The connecting rod 9 aligns the position of the blocking member 17 with the position of the fixed slot 8 and passes through the extension plate 7. The abutment 10 at one end of the connecting rod 9 first abuts against the extension plate 7. Since the blocking member 17 is threadedly connected to the connecting rod 9, rotating the blocking member 17 causes the position of the blocking member 17 to be misaligned with the fixed slot 8. The rotated blocking member 17 can abut against another set of extension plates 7. Thus, the two sets of extension plates 7 are fixed by the cooperation of the abutment 10 and the blocking member 17. At the same time, the first support plate 1 and the second support plate 3 after being flipped and folded are fixed to ensure stability when carried.
[0026] Reference Figure 3 , Figure 5 and Figure 6The leg support assembly 6 includes a hidden plate 601, which is disposed in the inner cavity of the second support plate 3. A telescopic rod 602 is fixedly connected to one side of the hidden plate 601. An elastic block 603 is slidably connected to the inner cavity of the telescopic rod 602. The surface of the elastic block 603 abuts against the inner wall of the second support plate 3. A second through groove 604 is provided on one side of the hidden plate 601. Through the leg support assembly 6, the hidden plate 601 in the leg support assembly 6 can support the feet or legs of taller injured persons. The hidden plate 601 can be connected to the second support plate 3 through the telescopic rod 602. The abutment between the elastic block 603 and the inner wall of the second support plate 3 ensures the damping of the hidden plate 601 and minimizes the possibility of the telescopic rod 602 and the hidden plate 601 sliding freely.
[0027] Reference Figure 1 , Figure 3 and Figure 5 One side of the first support plate 1 and the second support plate 3 are fixedly connected to a head hook and loop fastener 11. A head fixing block 12 is fixedly connected to the surface of the head hook and loop fastener 11. One side of the second support plate 3 is fixedly connected to a multi-functional hook and loop fastener 13. One side of the multi-functional hook and loop fastener 13 is fixedly connected to a limb fixing block 14 and a storage bag 15. There are four limb fixing blocks 14. One side of the first support plate 1 is fixedly connected to an upper limb hook and loop fastener 16. The limb fixing blocks 14 and the upper limb hook and loop fastener 16 are glued to each other. The hook and loop fasteners are designed such that the two sets of head hook and loop fasteners 11, the multi-functional hook and loop fasteners 13 and the two sets of upper limb hook and loop fasteners 16 all use the hook side of the hook and loop fastener. One side of the head fixing block 12, the four sets of limb fixing blocks 14 and the storage bag 15 are fixedly connected to the loop side of the hook and loop fastener (not shown in the figure).
[0028] When the first support plate 1 and the second support plate 3 are flipped and folded, the head fixing block 12 is attached to the head Velcro 11 of the second support plate 3, and the four sets of limb fixing blocks 14 and the storage bag 15 are attached to the multi-functional Velcro 13. When the first support plate 1 and the second support plate 3 are unfolded and used, the head fixing block 12 is torn off and transferred to the head Velcro 11 of the first support plate 1 to support and protect the head and neck of the injured person. Two of the four sets of limb fixing blocks 14 can be transferred to the upper limb Velcro 16 to fix the upper limb of the injured person. The other two sets of limb fixing blocks 14 are moved to the side of the multi-functional Velcro 13 to fix the legs of the injured person.
[0029] The storage pouch 15 can store additional straps, fixation straps, or medications. The storage pouch 15 is attached to the stretcher via the hook and loop side of the Velcro and the multi-functional Velcro 13, which improves the convenience of carrying other items and ensures the stretcher's multi-functionality.
[0030] Working principle: When the first support plate 1 and the second support plate 3 are folded together, the extension plate 7 and the fixing groove 8 are aligned with each other, and the two sets of fixing grooves 8 are interconnected. The connecting rod 9 aligns the position of the blocking member 17 with the position of the fixing groove 8 and passes through the extension plate 7. The abutment 10 at one end of the connecting rod 9 first abuts against the extension plate 7. Since the blocking member 17 is threadedly connected to the connecting rod 9, rotating the blocking member 17 causes the position of the blocking member 17 to be misaligned with the fixing groove 8, and the rotated blocking member 17 can abut against the other set of extension plates 7. Thus, the two sets of extension plates 7 are fixed by the cooperation of the abutment 10 and the blocking member 17, and at the same time, the first support plate 1 and the second support plate 3 after being flipped and folded are fixed to ensure stability when carried. The storage bag 15 can store additional straps, fixing straps or medicines. Furthermore, the storage bag 15 is attached to the multi-functional Velcro 13 via the hook and loop side and carried along with the stretcher. The multi-functional fixing strap 5 can be used as a carrying strap, allowing rescuers to carry the stretcher on their backs and free their hands. When the first support plate 1 and the second support plate 3 are unfolded, the multi-functional fixing strap 5 can be used as a fixing strap to fix the shoulder position of the injured person and ensure the stability of the injured person during transfer. Then, the head fixing block 12 is torn off and transferred to the head Velcro 11 of the first support plate to support and protect the head and neck of the injured person. Two of the four sets of limb fixing blocks 14 can be transferred to the upper limb Velcro 16 to fix the upper limb of the injured person. The other two sets of limb fixing blocks 14 are moved to the side of the multi-functional Velcro 13 to fix the legs of the injured person.
[0031] In addition, the hidden plate 601 in the leg support assembly 6 can support the feet or legs of taller injured persons. The hidden plate 601 can be connected to the second support plate 3 through the telescopic rod 602. The damping of the hidden plate 601 is ensured by the abutting cooperation between the elastic block 603 and the inner wall of the second support plate 3, so as to avoid the telescopic rod 602 and the hidden plate 601 from sliding freely.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
