[0002] Helicopter rescue is the use of helicopters for emergency rescue. It can reach work sites that are inaccessible by water or land more quickly, and carry out search and rescue, material transportation, air command and other tasks. It is the most effective emergency rescue commonly used in many countries around the world.

[0003] At present, many helicopter rescue hanger designs are relatively bulky and lack the necessary folding mechanism. This not only causes the hanger to take up a lot of space during transportation and storage, increasing the difficulty and cost of transportation, but also significantly affects the flight performance and load capacity of the helicopter when carrying the hanger. Especially in emergency rescue missions, the rapid response capability and flexibility of the helicopter are crucial, and the bulky hanger design is undoubtedly a major obstacle. The assembly and disassembly process is cumbersome, which not only increases the difficulty of operation, but may also delay precious rescue time and reduce the efficiency of field rescue. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides an auxiliary rescue hanger for a helicopter. Through this design, it effectively solves the problem that the conventional hanger design is relatively bulky and lacks the necessary folding mechanism. This not only causes the hanger to take up a lot of space during transportation and storage, increases the difficulty and cost of transportation, and increases the difficulty of operation, but may also delay precious rescue time and reduce the efficiency of field rescue.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: the present invention includes a base, a plurality of horizontal plates are arranged on the outer circumference of the top of the base, the outer side of each horizontal plate is rotatably connected to a vertical plate, the tops of the vertical plates are commonly connected to a steel cable, two handles are provided in the middle of the steel cable, and the two handles are symmetrically arranged with the base as the symmetry axis, a locking assembly is provided inside the base, a plurality of sliders are arranged on the outer circumference of the locking assembly, the sliders are slidably connected to the base, and hooks are provided on the inner sides of the tops of the vertical plates.

[0006] Preferably, the locking assembly includes a turntable, the bottom of which is rotatably connected to the base, and the top of which is provided with a rectangular block.

[0007] Preferably, a plurality of connecting rods are arranged on the top circumference of the turntable, and the outer sides of the connecting rods are rotatably connected to the inner sides of the sliders.

[0009] Preferably, a threaded block is provided at the bottom of the base, and a threaded pipe is connected to the outer side of the threaded block via threads.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The locking assembly can control the sliding distance of the slider. When the slider moves inward, the horizontal plate and the vertical plate can be folded upward at the same time to complete the folding of the device. The horizontal plate can be blocked by the slider to prevent it from folding upward during the lifting process, causing accidents. The threaded tube will move upward on the outer surface of the threaded block. The top height of the threaded tube is higher than the hinge point of the horizontal plate to prevent the horizontal bar from automatically opening after folding. Hooks are provided on the inner side of the top of the vertical plate. The hooks can be used to hang a nylon cover that matches the entire device, which is convenient for loading items inside the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is combined with Figure 1-Figure 5 The specific implementation methods of the present utility model are further described in detail.

[0019] The utility model includes a base 6, a plurality of horizontal plates 5 are arranged on the outer circumference of the top of the base 6, the horizontal plates 5 are rotatably connected to the base 6, the outer side of each horizontal plate 5 is rotatably connected to the vertical plate 4, and the top of the vertical plate 4 is commonly connected to a steel cable 1, and the steel cable 1 can provide tension for the four vertical plates 4. Two handles 3 are provided in the middle of the steel cable 1. The helicopter fixes the two handles 3 through lifting equipment, etc., and the height of the device is changed by controlling the height of the handles 3. The two handles 3 are symmetrically arranged with the base 6 as the symmetry axis. A locking assembly is provided inside the base 6, and a plurality of sliders 7 are arranged on the outer circumference of the locking assembly. The sliders 7 are slidably connected to the base 6. The locking assembly can control the sliding distance of the sliders 7, and the horizontal plates 5 can be blocked by the sliders 7 to prevent the horizontal plates 5 from folding upward during the lifting process, resulting in accidents. Hooks 2 are provided on the inner sides of the tops of the vertical plates 4.
