Description

Technical Field

[0001] The utility model relates to the technical field of rescue equipment, in particular to a backpack suspension device for rescue equipment. Background Art

[0002] Rescue equipment refers to equipment and tools specifically used to perform emergency rescue missions. They are widely used in disaster relief, rescue drills, accident site cleanup and other work. These equipment are of various types and have different functions. They are designed to improve rescue efficiency, ensure the safety of rescue personnel, and minimize losses caused by disasters and accidents.

[0003] In order to ensure that rescuers can carry various rescue equipment easily and freely, and maintain a high degree of mobility during the tense rescue process, we usually use a backpack suspension device as an important auxiliary tool. This device is not only used to carry rescue equipment, but also has a suspension function, allowing rescuers to perform suspension activities smoothly. Through the backpack suspension device, rescuers can perform various operations in the air, such as crossing obstacles, approaching trapped people, etc., so as to better cope with various complex and dangerous rescue scenarios.

[0004] For example, a rescue equipment carrying suspension device disclosed in publication number CN212178490U provides a rescue equipment carrying suspension device, including a backpack for carrying on both shoulders, a suspension frame provided above the backpack for hanging the rescue equipment, and a transmission device provided inside the suspension frame for suspending the rescue equipment at any position. The utility model carries the rescue equipment on the backpack, with a shoulder-carrying structure, which is easy to wear. A suspension frame is provided above the backpack, and the rescue equipment is fixed by the suspension frame. A transmission device is provided inside the suspension frame. After wearing, it is only necessary to pull the pull ring and use the carabiner and the load-bearing nylon rope to fix the rescue equipment. The transmission device includes a movable pulley set and a gas spring. According to the mechanical principles of physics, the movable pulley can reduce the nominal load force of the gas spring by multiples to reduce the pulling force of the rescuer. The entire system adopts the principle of gas compressibility to realize the up and down translation and suspension of the rescue equipment during the rescue process, thereby improving the rescue efficiency of the rescuer.

[0005] However, most of the rescue equipment currently on the market still require rescuers to manually adjust the lifting height of the back suspension device. This manual adjustment method will increase the difficulty and workload of rescuers when performing tasks. When manually adjusting the lifting height, rescuers need to invest extra energy and time, which will cause a certain consumption of their physical strength. Especially in emergency rescue situations, manual adjustment may not only delay the rescue time, but also may cause other safety problems due to improper operation. In addition, there are certain safety hazards in manually adjusting the lifting height of the back suspension device. During the operation, rescuers may be distracted or make operational errors, causing the equipment to fall off or lose control, which may not only endanger the safety of the rescuers themselves, but may also cause unnecessary harm to the trapped persons or other rescuers.

[0023] A transmission structure 2 is provided on one side of the top of the main back frame 11 .

[0024] The transmission structure 2 includes a working box 21 fixedly connected to the main backpack 11, and the inner cavity of the working box 21 is provided with a dual-axis motor 22. The two output shafts of the dual-axis motor 22 are fixedly connected to a worm 23. One side of the inner cavity of the working box 21 is rotatably connected to two symmetrically arranged adjusting wheels 24, and one side of the adjusting wheel 24 is fixedly connected to a worm gear 25, which is engaged with the worm gear 23. The inner cavity of the adjusting wheel 24 is rotatably connected to a rope 26, and one end of the rope 26 passes through the top of the working box 21 and is fixedly connected to a connecting buckle 27.

[0025] Specifically, both ends of the top of the shoulder strap 14 are fixedly connected with an adjustment buckle 16, the inner cavity of the adjustment buckle 16 is snapped with the two ends of the bottom of the shoulder strap 14, and both sides of the shoulder strap 14 are fixedly connected with an auxiliary belt 17, and the two auxiliary belts 17 are connected by a fixed buckle.

[0026] In this embodiment, by adjusting the buckle 16 and the auxiliary strap 17, firstly, it is convenient for the user to adjust the length of the shoulder strap 14 according to his or her own physique, thereby improving the adaptability to the user; secondly, it can further improve the stability of the user when wearing it.

[0027] Specifically, a support rod 28 is fixedly connected to one side of the worm gear 25 , and one end of the support rod 28 is rotatably connected to the working box 21 .
