[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 3 The present invention provides an external loading device for a luggage case, including a fixed frame 1 and a movable rod 6. Mounting edges 2 are provided on both sides of the fixed frame 1. Both mounting edges 2 are integrally formed structures on the surface of the fixed frame 1. Open grooves 3 are provided on the surfaces of both mounting edges 2. Both ends of the movable rod 6 are slidably inserted into the open grooves 3 on the surfaces of the mounting edges 2. One of the mounting edges 2 is rotatably connected to a screw rod 5 in the open groove 3 through a bearing. The screw rod 5 is screwed through one end of the movable rod 6. Both ends of the movable rod 6 are integrally formed with a slider structure. Slide grooves are provided on the surfaces of the mounting edges 2 at the open groove 3. The movable rod 6 is slidably connected to the slide grooves at the open groove 3 through the slider. The stability of the movable rod 6 can be further increased, ensuring that it will not be displaced during movement, and having good pressure protection effect. The end of the screw rod 5 passes through the surface of the mounting edge 2 and is keyed to a rotating wheel 4.

[0022] The fixing frame 1 includes an outer shell 11, a cushioning block 12, a reinforcement layer 13, and a pressure-resistant layer 14. The reinforcement layer 13 is laid on the inner wall of the outer shell 11 on one side, and the pressure-resistant layer 14 is laid on the inner wall of the outer shell 11 on the other side. The cushioning blocks 12 are evenly arranged between the pressure-resistant layer 14 and the reinforcement layer 13. The layered structure is provided to increase the pressure and impact resistance of the fixing frame 1, and the safety of the overall structure is enhanced. The reinforcement layer 13 is paved with steel sheet material, the pressure-resistant layer 14 is paved with rubber material, and the cushioning blocks 12 are made of foam material evenly bonded in sequence. The use of the reinforcement layer 13 to ensure overall rigidity and strength can effectively ensure overall resistance and safety. The material of the pressure-resistant layer 14 can effectively provide toughness and ductility to avoid damage due to extrusion.

[0023] The first mounting brackets 7 are symmetrically mounted on both sides of the surface of the movable rod 6 through bearing cooperation. The central parts of the two first mounting brackets 7 are symmetrically mounted with the second mounting brackets 8 through connecting shafts. The two second mounting brackets 8 are symmetrically mounted at one end of the two mounting edges 2 through shaft cooperation. Two fabric layers 10 are sleeved between the two first mounting brackets 7 and the two second mounting brackets 8. The fabric layer 10 includes an outer skin layer 101, an inner lining layer 102 and a reinforcement layer 103. The inner lining layer 102 and the reinforcement layer 103 are sequentially laid between the outer skin layers 101. The fabric layer 10 has good ductility and toughness, and can expand or contract accordingly with the movement of the mounting bracket without being damaged. The outer skin layer 101 is woven from nylon wire material and polyamide fiber material, the inner lining layer 102 is woven from nylon fiber, and the reinforcement layer 103 is filled with rubber material.

[0024] When in use, manually turn the wheel 4 to control the rotation of the screw rod 5, and then adjust the position of the moving rod 6. As the moving rod 6 moves downward, the two first mounting racks 7 are forced to open outward, during which the second mounting rack 8 is also driven to open outward, thereby cooperating with the fabric layer 10 to form a storage frame, which can be used to place some personal items, such as paper towels, tea cups or purchased snacks and milk tea, which are easy to store. After the storage is completed, the wheel 4 can be controlled to retract the mounting rack to a certain angle according to the situation, so that the stored items can be stored more tightly and securely. The fabric layer 10 has good toughness enough to complete such operations. When storage is not needed, the wheel 4 is controlled to move the moving rod 6 upward, and finally the first mounting rack 7 and the second mounting rack 8 are retracted to the limit position to close the loading structure. At this time, it will not take up too much space and can also provide a protective function for the suitcase body.
