[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a high-strength lightweight trolley case, including a first case body 1 and a second case body 2. A corner of the first case body 1 and a corner of the second case body 2 are rotatably connected. A first reinforcing strip 3 is fixedly installed on the surface of the first case body 1 and the surface of the second case body 2. A second reinforcing strip 4 is fixedly connected between the first reinforcing strips 3. The first reinforcing strips 3 and the second reinforcing strips 4 are perpendicular to each other. A protective pad 5 is fixedly installed at the corner of the edge of the first case body 1. A first anti-collision protrusion 6 is fixedly installed on the surface of the protective pad 5.

[0028] Protective frames 7 are fixedly installed at the edges of the openings of the first housing 1 and the second housing 2. Support blocks 8 are fixedly installed on the outer wall of the second housing 2. Second anti-collision protrusions 9 are fixedly connected to both ends of the support blocks 8. First cavities 10 are opened inside the first anti-collision protrusions 6 and the second anti-collision protrusions 9. Filling blocks 11 are fixedly installed on the inner wall of the first cavity 10. Support blocks 12 are fixedly installed on both sides of the filling blocks 11. The other end of the support blocks 12 is fixedly connected to the inner wall of the first cavity 10. Shaping blocks 13 are fixedly installed at the corners of the inner walls of the first cavity 10. Shaping blocks 13 are fixedly connected to the corners of the filling blocks 11.

[0029] The specific settings and functions of this embodiment are described below. The first box 1 and the second box 2 are rotatably connected to form a complete trolley case. The pull rod is set on the outer wall of the second box 2. In use, the first box 1 serves as the top of the trolley case and the second box 2 serves as the bottom of the trolley case. When placing items, the second box 2 is placed on the ground. At this time, the first reinforcing strip 3 and the second reinforcing strip 4 on the surface of the second box 2 will contact the ground, thereby avoiding excessive friction between the second box 2 and the ground.

[0030] Furthermore, since the first reinforcing strip 3 and the second reinforcing strip 4 are perpendicular to each other, and both the first reinforcing strip 3 and the second reinforcing strip 4 are connected together with the protective frame 7, a frame structure for shaping and reinforcement will be formed on the surface of the first case 1 and the surface of the second case 2. This ensures the structural strength of the first case 1 and the second case 2, and while improving the structural strength, it will not cause the weight of the entire suitcase to become too heavy, making it convenient for quick movement and carrying.

[0031] During the movement of the suitcase, the protective pad 5 and the first anti-collision protrusion 6 set at the edge of the first suitcase 1 can play a role in preventing collisions. The edge of the second suitcase 2 is provided with a support block 8 and a second anti-collision protrusion 9. The first anti-collision protrusion 6 and the second anti-collision protrusion 9 have the same structure, only the length is different. When the second anti-collision protrusion 9 collides with an object, there is a shaping block 13 at its corner to support it and ensure that the corner will not be damaged. Support blocks 12 connected to the filling block 11 are provided on the front and the side to ensure that the surfaces of the first anti-collision protrusion 6 and the second anti-collision protrusion 9 can withstand the impact. The existence of the first cavity 10 ensures that the weight of the first anti-collision protrusion 6 and the second anti-collision protrusion 9 will not be too large, so as not to affect the normal movement of the suitcase.

[0032] Example 2: Figure 3 and Figure 5 As shown, a thickened plate 14 is fixedly installed at the bottom of the second housing 2. A second cavity 15 is opened inside the thickened plate 14. Solid plates 19 are fixedly connected to both ends of the thickened plate 14. The solid plates 19 are fixedly connected inside the second housing 2. A T-shaped rod 17 is fixedly installed at the junction of the second cavity 15 and the solid plate 19. The T-shaped rod 17 is arranged horizontally. A connecting rod 16 is fixedly installed on the inner wall of the second cavity 15. An X-shaped support frame 18 is fixedly connected between two adjacent connecting rods 16.

[0033] The overall effect of this embodiment is that when objects are placed inside the box, the thickened plate 14 can withstand greater pressure. Solid plates 19 are connected to both ends of the thickened plate 14 and directly connected to the second box 2 to ensure the structural stability of the connection. A second cavity 15 is provided inside the thickened plate 14 to reduce its own weight. A T-shaped rod 17 is provided at the connection between the thickened plate 14 and the solid plate 19. When the suitcase is in a vertical position, it can ensure that the bottom of the box can withstand the pressure of the contents inside.

[0034] Multiple connecting rods 16 are evenly spaced inside the second cavity 15, and an X-shaped support frame 18 is provided between two adjacent connecting rods 16. The end of the X-shaped support frame 18 is connected to the junction of the connecting rod 16 and the second cavity 15. When subjected to pressure, the X-shaped support frame 18 can evenly distribute the pressure and impact force to all parts of the second housing 2.

[0035] The usage and working principle of this device are as follows: The first box 1 and the second box 2 are directly rotatably connected to form a complete trolley case. The trolley is set on the outer wall of the second box 2. The first reinforcing strip 3 and the second reinforcing strip 4 on the outer walls of the first box 1 and the second box 2 are perpendicular to each other, and the first reinforcing strip 3 and the second reinforcing strip 4 are both connected to the protective frame 7 to form a frame structure, thereby ensuring the structural strength of the first box 1 and the second box 2.

[0036] When placing items, the second box 2 is placed on the ground. At this time, the first reinforcing strip 3 and the second reinforcing strip 4 on the surface of the second box 2 will be in contact with the ground. When placing objects into the box, the thickened plate 14 can withstand greater pressure. When under pressure, the X-shaped support frame 18 can evenly distribute the pressure and impact force to all parts of the second box 2.

[0037] During the movement of the suitcase, the suitcase is in a vertical position. The T-shaped bar 17 and the solid plate 19 can ensure that the bottom of the suitcase can withstand the pressure of the contents. The protective pad 5 and the first anti-collision protrusion 6 set at the edge of the first suitcase 1 can play the role of anti-collision. The edge of the second suitcase 2 is provided with a support block 8 and a second anti-collision protrusion 9. The first anti-collision protrusion 6 and the second anti-collision protrusion 9 have the same structure, only the length is different, and both are used for anti-collision.

[0038] When the first anti-collision bump 6 and the second anti-collision bump 9 collide with an object, a shaping block 13 is provided at the corner to support it and ensure that the corner is not damaged. Support blocks 12 connected to the filling block 11 are provided on the front and side to ensure that the surfaces of the first anti-collision bump 6 and the second anti-collision bump 9 can withstand the impact.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
