[0025] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0027] Example 1: Refer to Figures 1 - 5 As shown in the figure: An anti-deformation trolley case includes a first box body 8. A trolley body 2 is slidably connected inside the first box body 8. One end of the trolley body 2 is fixedly connected with a handle 1. An adjusting mechanism is arranged on one side of the handle 1. The adjusting mechanism includes a folding frame 14, a connecting shaft 20 and a second limiting bolt 23. One side of the folding frame 14 is fixedly connected with the first box body 8. The other side of the folding frame 14 is fixedly connected with a first zipper assembly 13. One side of the first zipper assembly 13 is fixedly connected with a third box body 11. And an extension block 24 is fixedly connected to one side of the folding frame 14. The second limiting bolt 23 is connected inside the extension block 24 by threads. One end of the second limiting bolt 23 is connected with a limiting rod 19 by threads. A fixing block 22 is fixedly connected to the outer ring surface of the limiting rod 19. One side of the fixing block 22 is fixedly connected with the first box body 8. A support bar 21 is arranged on one side of the first box body 8. The support bars 21 are hinged by the connecting shaft 20. And a rhombus structure is formed by the connecting shaft 20 and the support bars 21. One of the connecting shafts 20 is fixedly connected with the first box body 8. The other connecting shaft 20 is fixedly connected with one side of the folding frame 14.

[0028] By using the connection between the trolley body 2 and the handle 1, it is convenient to adjust the extending length of the trolley body 2, thereby assisting the movement of the entire trolley case. The distance between the first box body 8 and the third box body 11 can be adjusted through the retractable folding frame 14, and then the internal capacity of the entire trolley case can be adjusted. The connection between multiple support bars 21 can be realized through the connecting shaft 20. By using the rhombus structure formed by the connecting shaft 20 and the support bars 21, one side of the folding frame 14 can be strengthened, reducing the damage caused to the folding frame 14 by external forces. The fixing block 22 facilitates the installation and use of the limiting rod 19 on one side of the first box body 8. The extension block 24 can assist in the connection between the folding frame 14 and the second limiting bolt 23, facilitating the support of the extension block 24 for the second limiting bolt 23. By connecting the second limiting bolt 23 and the limiting rod 19, the stretching position of the folding frame 14 can be limited, avoiding the loosening of the folding frame 14 during subsequent use, and thus improving the stability of the entire trolley case during use. By connecting the third box body 11 and the folding frame 14 through the first zipper assembly 13, it is convenient to open and close the trolley case.

[0029] Example 2: As Figures 1 - 4As shown, on one side of the third box body 11, there is a fixed connection with an L-shaped frame 10. On one side of the L-shaped frame 10, there is a fixed connection with a support rod 16. On one side of the support rod 16, there is a rotational connection with the second box body 9. On one side of the second box body 9, there is a fixed connection with a second zipper assembly 15. On one side of the second zipper assembly 15, there is a fixed connection with the third box body 11. On one side of the inner wall of the second box body 9, there is a fixed connection with a first reinforcing rod 17. On one side of the first reinforcing rod 17, there is a second reinforcing rod 18 arranged. On one side of the second reinforcing rod 18, there is a fixed connection with the inner wall of the third box body 11. On one side of both the third box body 11 and the first box body 8, there are bolt connections with second universal wheels 7. On one side of the first box body 8, there is a fixed connection with a clamping strip 12. On one side of the clamping strip 12, there is a clamping connection with a mounting plate 6. On one side of the mounting plate 6, there is a storage groove opened. Inside the storage groove, there is a lapping connection with an auxiliary frame 5. On one side of the auxiliary frame 5, there is a rotational connection with the mounting plate 6 through a damping rotating shaft. On one side of the mounting plate 6, there is a rotational connection with a first universal wheel 4. On one side of the first universal wheel 4, there is a clamping connection with the mounting plate 6. On one side of the mounting plate 6, there is a fixed connection with a positioning block 25. On one side of the positioning block 25, there is a lapping connection with the first universal wheel 4. Inside the positioning block 25, there is a through insertion of a first limit bolt 3. One end of the first limit bolt 3 is threadedly connected with the first universal wheel 4.

[0030] The opening and closing of the second box body 9 can be assisted by the second zipper assembly 15. The L-shaped frame 10 can be used to support and reinforce one side of the third box body 11, improving the use strength of one side of the L-shaped frame 10. The support rod 16 can be used to support one side of the second box body 9. The use strength of the second box body 9 can be improved by the first reinforcing rod 17. The strength of one side of the third box body 11 can be improved by the second reinforcing rod 18, thereby reducing the deformation of the second box body 9 and the third box body 11 during use. The second universal wheels 7 facilitate the vertical movement of the entire luggage case. The clamping strip 12 can assist in the connection between the mounting plate 6 and the first box body 8. The mounting plate 6 can support one side of the auxiliary frame 5, facilitating the use and storage of the auxiliary frame 5. When the auxiliary frame 5 is stored, the volume of the entire device can be reduced. The rotation range of the first universal wheel 4 can be limited by the positioning block 25. The connection between the first universal wheel 4 and the positioning block 25 can be achieved by the first limit bolt 3, further limiting the use position of the first universal wheel 4, improving the stability of the first universal wheel 4 during use, facilitating the sliding of the luggage case when horizontally placed, and reducing the wear on the first box body 8.

[0031] Usage method and working principle of this device: First, the usage width of the folding frame 14 can be adjusted according to the number of luggage items. When there is less luggage, the folding frame 14 is in a contracted state. When there is more luggage, pull the folding frame 14 to the side away from the box body one 8, and the inclination angle of the support bar 21 in the diamond structure changes. After adjustment, connect the end of the limit bolt two 23 to the limit rod 19 to fix the position of the folding frame 14. Then, the luggage can be placed into the entire suitcase. Pull the zipper assembly one 13 to separate one side of the folding frame 14 from the box body three 11, and pull the zipper assembly two 15 to separate one side of the box body two 9 from the box body three 11, which is convenient for taking out the luggage placed in different positions. Rotate the auxiliary frame 5 on one side of the mounting plate 6 so that the auxiliary frame 5 is perpendicular to the mounting plate 6. At this time, small tools such as umbrellas and teacups can be hung on the auxiliary frame 5. When the suitcase needs to be moved horizontally, rotate the universal wheel one 4 on one side of the mounting plate 6 so that one side of the universal wheel one 4 abuts against the positioning block 25, and then rotate the limit bolt one 3 to connect the limit bolt one 3 to the universal wheel one 4, and the suitcase can be pushed to move in the horizontal direction. Through the diamond structure, the strength of one side of the folding frame 14 can be improved, and the box body three 11 can be reinforced by the L-shaped frame 10, thereby reducing the deformation of the suitcase during use.
