[0021] Such as Figure 1 、 Figure 2As shown in the figure, a trackless adapter of the present invention includes a body 11, a sleeve 12, and a pin shaft 13. The body 11 is made of an elastic material. The cross-section of the body 11 is fan-shaped. An accommodation space for placing the sleeve 12 is provided inside the body 11. The sleeve 12 is placed in the accommodation space. A through hole is provided on the top plate of the sleeve 12. The pin shaft 13 is arranged along the radial direction of the body 11. Part of the pin shaft 13 is located inside the sleeve 12 and part of it passes through the through hole and extends outside the sleeve 12. One end of the pin shaft 13 located inside the sleeve 12 is connected to the bottom plate of the sleeve 12. The part of the pin shaft 13 extending outside the sleeve 12 is used to extend into the pin hole of the transported item. Specifically, the sleeve is cylindrical. As Figure 3 shown in the figure, during use, a plurality of trackless adapters 01 of the present invention are placed between the cylindrical packaging box 02 and the transported item 03. In this embodiment, four trackless adapters are placed. The transported item 03 is a large-scale rain enhancement rocket. The inner arc surface of the trackless adapter is in full contact with the outer wall of the large-scale rain enhancement rocket. Four pin holes are provided on the large-scale rain enhancement rocket. The pin shafts 13 of the four trackless adapters are respectively arranged in one pin hole. The outer arc surface of the trackless adapter is in full contact with the inner wall of the cylindrical packaging box 02, playing a role of support and vibration reduction. When the large-scale rain enhancement rocket moves in the cylindrical packaging box, the trackless adapter moves synchronously with the large-scale rain enhancement rocket, and the pin shaft 13 plays a guiding role. A trackless adapter of the present invention, since it includes a body 11, a sleeve 12, and a pin shaft 13, a through hole is provided on the top plate of the sleeve 12, part of the pin shaft 13 is located inside the sleeve 12 and part of it passes through the through hole and extends outside the sleeve 12, and the part of the pin shaft 13 extending outside the sleeve 12 is used to extend into the pin hole of the transported item. Therefore, by placing the trackless adapter of the present invention between the large-scale rain enhancement rocket and the cylindrical packaging box 02, the large-scale rain enhancement rocket can be accurately positioned, supported, and vibration-reduced, avoiding damage during transportation, and providing a guiding role for the large-scale rain enhancement rocket during movement.

[0022] Optionally, it further includes a buffer layer 16. The buffer layer 16 is connected to the inner arc surface of the body 11. The buffer layer 16 is formed by bonding a neoprene sponge layer and a fiberglass cloth layer to each other, avoiding adhesion between the buffer layer 16 and the surface of the large-scale rain enhancement rocket. Specifically, the edge of the inner arc surface of the body 11 is rounded. The buffer layer 16 entirely wraps the edge to avoid stress concentration. After verification by the compression strength test, the maximum deformation of the buffer layer 16 can reach more than 80% of the original thickness, ensuring that buffer protection is provided for the large-scale rain enhancement rocket under extreme transportation conditions and meeting the transportation requirements of the large-scale rain enhancement rocket.

[0023] Optionally, the neoprene sponge layer and the fiberglass cloth layer are bonded to each other through epoxy resin glue.

[0024] Optionally, it further includes a rib plate 14. The rib plate 14 is arranged inside the sleeve 12 and is connected to the bottom plate of the sleeve 12. Specifically, the rib plate 14 is a flat plate, and the rib plate 14 is connected to the bottom plate of the sleeve 12 by screws. By providing the rib plate 14, the strength of the trackless adapter of the present invention is increased.

[0025] Optionally, it further includes a guide ring 15. The hardness of the guide ring 15 is greater than that of the body 11. The guide ring 15 is sleeved outside the pin shaft 13. Part of the guide ring 15 is located inside the sleeve 12, and part of it is located between the part of the pin shaft 13 extending outside the sleeve 12 and the body 11. By providing the guide ring 15, the pin shaft 13 can be prevented from being damaged when subjected to an impact force.

[0026] Optionally, a first boss 151 is provided on the inner wall of the middle part of the guide ring 15, and a second boss is provided on the outer wall of the pin shaft 12. The first boss 151 is matched with the second boss, and the first boss 151 is sleeved on the second boss. During use, when the inner arc surface of the trackless adapter is subjected to the pressure of a large-scale rain enhancement rocket, the guide ring 15 drives the pin shaft 12 to move away from the large-scale rain enhancement rocket through the first boss 151.

[0027] Optionally, a third boss 152 is provided on the outer wall of the bottom of the guide ring 15. The third boss 152 is used to cooperate with the top plate of the sleeve 12 to limit the position of the guide ring 15. By providing the third boss 152, the guide ring 15 is prevented from coming out of the sleeve 12.

[0028] Optionally, a plurality of weight reduction grooves 111 are provided on the body 11. By providing the weight reduction grooves 111, the weight of the body 11 is reduced, thereby reducing the weight of the trackless adapter of the present invention and making the trackless adapter of the present invention more convenient to use.

[0029] Optionally, there are two weight reduction grooves 111. The two weight reduction grooves 111 are symmetrically arranged along the circumferential direction of the body 11 to form a "work" shape for the body 11, which not only reduces the weight of the body 11 but also enables the body 11 to have good pressure-bearing performance.

[0030] Optionally, the body 11 is made of polymethacrylimide material, so that the body 11 has a high compressive strength, high specific strength and specific modulus. The pin shaft 13 and the sleeve 12 are made of metal materials.

[0031] The above-described embodiments are only descriptions of the preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
