Description

Technical Field

[0001] This utility model belongs to the field of rescue shovel technology, and specifically relates to a multi-functional rescue shovel. Background Technology

[0002] In emergency rescue scenarios, rescue shovels are a crucial tool. They are typically distinguished from entrenching tools, often featuring a long shovel design. Their long handle and wide head give them a significant advantage in digging through rubble and clearing obstacles, efficiently creating rescue channels and helping rescuers quickly reach the location of trapped individuals.

[0003] However, current rescue shovels have revealed several shortcomings in practical applications. The most prominent is their separate design from stretchers. During a rescue operation, rescue shovels are used to painstakingly dig and clear the scene to create conditions for rescuing the injured; simultaneously, once an injured person is found, a stretcher is urgently needed to transfer them. The fact that these two tools operate independently leads to significant inconvenience. In remote mountainous areas where vehicles cannot easily access, or in narrow streets with complex road conditions where medical personnel cannot quickly reach, rescuers often need to carry heavy loads and trek long distances to the rescue site. Carrying both a rescue shovel and a stretcher at the same time undoubtedly increases their burden greatly, not only hindering their movement but also consuming a great deal of energy and delaying precious rescue time.

[0004] In view of this, this application proposes a multi-functional rescue shovel to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a multi-functional rescue shovel. When it is necessary to transfer the injured, rescuers simply grasp the curved blade and pull it outwards. As the curved blade moves, the nylon fabric rolled up on the outside of the rotating shaft is pulled out from the hollow rotating rod. During this process, the nylon fabric gradually unfolds, ultimately forming a temporary emergency stretcher together with the rescue shovel. This achieves the integration of a stretcher and a rescue shovel, solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A multi-functional rescue shovel includes: a stretcher mechanism comprising a hollow shovel handle, the hollow shovel handle having a rotatable shaft for winding nylon fabric inside, the nylon fabric being disposed outside the shaft, an arc-shaped piece on one side of the nylon fabric, and two sets of handles mounted on the outer side of the arc-shaped piece; the hollow shovel handle, the nylon fabric, and the arc-shaped piece together forming a stretcher; a shovel head mechanism comprising a metal shovel head for digging, the metal shovel head having a cutting edge on one side for cutting obstacles, and a sawing edge on the other side for sawing obstacles; and a positioning mechanism, the hollow shovel handle and the arc-shaped piece having a set of threads on their upper and lower sides respectively, and a set of screw cylinders, number one and number two, for positioning the arc-shaped piece being threadedly connected to the upper and lower sides of the hollow shovel handle respectively.

[0008] In a preferred embodiment, a set of partitions is installed on the upper and lower sides of the hollow shovel, and the upper and lower ends of the rotating shaft are rotatably connected to the two sets of partitions.

[0009] In a preferred embodiment, a rotating head is connected to the hollow shovel rod extending from the upper end of the rotating shaft, and the diameter of the rotating head is greater than the inner diameter of the hollow shovel rod.

[0010] In a preferred embodiment, one end of the nylon fabric is fixedly connected to the rotating shaft, and the other end is fixedly connected to the arc-shaped piece, with the nylon fabric wrapped around the outside of the rotating shaft.

[0011] In a preferred embodiment, the hollow shovel bar has an arc-shaped opening on one side, and the shape of the arc-shaped opening matches the shape of the arc-shaped piece.

[0012] In a preferred embodiment, the grip has an L-shaped structure, and the two sets of grips are installed in a mirror image.

[0013] In a preferred embodiment, a foot pedal is installed above the metal shovel head, and limiting rods are installed on both sides of the foot pedal. The lower end of the hollow shovel is fixedly connected to the foot pedal.

[0014] In a preferred embodiment, a stone-crushing cone is installed at the upper end of the first screw barrel, and the rotating head is located inside the first screw barrel.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In emergency rescue scenarios, time is of the essence, making the efficiency and convenience of rescue tools paramount. To address the numerous inconveniences caused by the separation of traditional rescue shovels and stretchers, an innovative combined rescue shovel has been designed. This rescue shovel incorporates a unique stretcher mechanism on top of a conventional design. Inside the hollow shovel handle, a rotating shaft is installed, with nylon fabric tightly rolled up on its outer side. One end of the nylon fabric is fixed to the rotating shaft, and the other end is connected to an arc-shaped plate. When it is necessary to transfer a casualty, rescuers simply grasp the arc-shaped plate and pull it outwards. As the arc-shaped plate moves, the nylon fabric rolled up on the outer side of the rotating shaft is pulled out from the hollow rotating shaft. During this process, the nylon fabric gradually unfolds, ultimately forming a temporary emergency stretcher together with the rescue shovel. This innovative design integrates the stretcher and rescue shovel, avoiding the inconvenience of carrying two separate tools, significantly reducing the burden on rescuers, and allowing them to move more easily and quickly to the rescue site.

[0017] 2. To ensure the rescue shovel's stability and reliability during excavation, a positioning mechanism was designed. This mechanism utilizes a threaded connection principle to fix the arc-shaped piece. When rescuers need to use the rescue shovel for excavation, they rotate the No. 1 and No. 2 screw barrels to connect them to the arc-shaped piece and the hollow shovel rod, thus positioning the arc-shaped piece. During excavation, the arc-shaped piece remains stable and will not easily fall off or loosen due to vibration or collision, allowing the rescue shovel to smoothly perform its excavation function.

[0018] 3. To enhance the functionality of the rescue shovel, a blade and serrated sections are designed on both sides of the metal shovel head. The blade is sharp and can efficiently cut obstacles; the serrated sections can saw through hard objects such as tree roots. Additionally, a rock-crushing cone is installed above the first screw barrel, which can be used to hammer and break rocks, concrete fragments, etc., improving the overall functionality of the rescue shovel.

[0026] 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 protection scope of the present utility model.

[0027] like Figures 1 to 5 The image shows a multi-functional rescue shovel, comprising: a stretcher mechanism 1, including a hollow shovel bar 11, with a rotating shaft 15 inside the hollow shovel bar 11 for rotatably winding nylon cloth 16, and the nylon cloth 16 located outside the rotating shaft 15. An arc-shaped piece 12 is provided on one side of the nylon cloth 16, and two sets of handles 14 are installed on the outside of the arc-shaped piece 12. The hollow shovel bar 11, the nylon cloth 16, and the arc-shaped piece 12 together form a stretcher; a shovel head mechanism 2, including a metal shovel head 21 for digging, with a cutting edge 25 on one side of the metal shovel head 21 and a saw tooth 22 on the other side for sawing obstacles; and a positioning mechanism 3, with a set of threads on the upper and lower sides of the hollow shovel bar 11 and the arc-shaped piece 12, and a set of screw cylinders 31 and 33 for positioning the arc-shaped piece 12 respectively. The hollow shovel 11 has a set of partitions installed on the upper and lower sides. The upper and lower ends of the rotating shaft 15 are rotatably connected to the two sets of partitions. The blades 25 and serrated parts 22 on both sides of the metal shovel head 21 can be used to cut and split soft obstacles and saw harder objects such as tree roots.

[0028] like Figure 3 and Figure 5 As shown: The upper end of the rotating shaft 15 extends out of the hollow shovel 11 and is connected to the rotating head 17. The diameter of the rotating head 17 is greater than the inner diameter of the hollow shovel 11.

[0029] like Figure 1 and Figure 3 As shown: one end of the nylon cloth 16 is fixedly connected to the rotating shaft 15, and the other end is fixedly connected to the arc-shaped piece 12. The nylon cloth 16 is wrapped around the outside of the rotating shaft 15. When the rotating head 17 is rotated, the rotating shaft 15 is rotated to wind up the nylon cloth 16.

[0030] The hollow shovel 11 has an arc-shaped opening 13 on one side. The shape of the arc-shaped opening 13 matches the shape of the arc-shaped piece 12. The arc-shaped piece 12 is inserted into the arc-shaped opening 13 on the hollow shovel 11. Then, the first screw 31 and the second screw 33 are rotated so that they are tightly screwed into the hollow shovel 11 and the arc-shaped piece 12 inserted into the arc-shaped opening 13 through threads, thereby firmly positioning the arc-shaped piece 12.

[0031] like Figure 1 and Figure 2 As shown: the grip 14 has an L-shaped structure, and the two sets of grips 14 are installed in a mirror image.

[0032] like Figures 1 to 3 As shown: A foot pedal 23 is installed above the metal shovel head 21, and limit rods 24 are installed on both sides of the foot pedal 23. The lower end of the hollow shovel rod 11 is fixedly connected to the foot pedal 23. During the excavation process, the metal shovel head 21 can be subjected to force by stepping on the foot pedal 23, and the design of the limit rods 24 can prevent the foot from slipping off the sides of the foot pedal 23 when stepping on the foot pedal 23.

[0033] like Figures 1 to 3 As shown: A rock-crushing cone 32 is installed at the upper end of the first screw cylinder 31, and the rotating head 17 is located inside the first screw cylinder 31. The rock-crushing cone 32 above the first screw cylinder 31 can powerfully hammer and break hard obstacles such as rocks and concrete fragments.

[0034] In practical use, the working principle of this utility model is as follows:

[0035] In emergency rescue scenarios, when it is necessary to transfer the injured, rescuers only need to grasp the handle 14 and pull the arc-shaped plate 12 outward. The arc-shaped plate 12 then exerts a traction effect, causing the nylon cloth 16 wrapped around the outside of the rotating shaft 15 to gradually unfold. During this process, the movement of the nylon cloth 16 will drive the rotating shaft 15 to rotate smoothly. After the nylon cloth 16 is fully unfolded, it, together with the arc-shaped plate 12 and the hollow shovel 11, forms a temporary emergency stretcher. At this time, the injured person is placed steadily on the nylon cloth 16, and the rescuer firmly grasps the hollow shovel 11 with one hand and the handle 14 with the other hand, and can then lift the injured person to achieve safe transfer.

[0036] During excavation, the first screw barrel 31 is rotated to disengage it from the hollow shovel handle 11. The rotating head 17 is then rotated, causing the shaft 15 to rotate and winding up the nylon cloth 16. After winding, the arc-shaped piece 12 is inserted into the arc-shaped opening 13 on the hollow shovel handle 11. The first screw barrel 31 and the second screw barrel 33 are then rotated to tightly screw themselves onto the hollow shovel handle 11 and the arc-shaped piece 12 embedded in the arc-shaped opening 13, respectively, thus firmly positioning the arc-shaped piece 12. During excavation, even under strong vibrations or frequent collisions, the arc-shaped piece 12 remains stable and will not easily fall off or loosen, ensuring the stable operation of the rescue shovel's excavation function. In rescue practice, the cutting edges 25 and serrated edges 22 on both sides of the metal shovel head 21 can be used to cut and split soft obstacles and saw harder objects such as tree roots, respectively. At the same time, by gripping the hollow shovel handle 11 and using the rock-breaking cone 32 above the screw barrel 31, the shovel can powerfully hammer and break hard obstacles such as rocks and concrete fragments, enhancing its ability to cope with complex rescue environments.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
