For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figure 1-5 As shown, a luggage case that can be used in combination comprises a body 1 and a front cover 2 covering the body 1, a pull rod 3 is provided at the upper end of the body 1, and universal wheels 4 are provided at the lower ends of the body 1 and the front cover 2, respectively, a square groove 6 is provided on a side 5 of the body 1 opposite to the front cover 2, a flap 7 is installed in the square groove 6, and the flap 7 comprises an upper bottom edge 8, a lower bottom edge 9 and two side edges 10, wherein the two sides of the lower bottom edge 9 are respectively installed in the square groove 6 through a rotating shaft, and the rotating shaft is parallel to the lower bottom edge 9, and the rotating shaft can be rotated to turn the flap 7 in a horizontal state (such as Figure 2 as shown) and vertical state (as shown Figure 1When the flap 7 is in a vertical state, it is embedded in the square groove 6. The two sides 10 are respectively provided with notches 11 near the upper bottom edge 8. The part between the notch 11 and the upper bottom edge 8 is set as a mounting portion 12. The mounting portion 12 is provided with a threaded hole. The two ends of the threaded hole are respectively connected to the notch 11 and the upper bottom edge 8. The threaded hole is connected with a screw 13. The nut 14 of the screw 13 is located in the notch 11. When a family travels, they carry two such suitcases. The flap 7 is buckled from the square groove 6 so that the flap 7 is in a horizontal state, and the two flaps are relatively close. The threaded holes of the two flaps are respectively connected, and one of the nuts 14 is turned so that the screw 13 enters the threaded hole of the other flap, and the splicing of the two flaps is completed, so that a space for children to sit is formed between the two suitcases. The two suitcases can be quickly connected into one. The child sits between the two suitcases, the center of gravity is low, and there is no risk of the suitcases overturning. Plastic bags, school bags and other items can also be placed on the two connected flaps 7. The two suitcases can be easily moved by pushing one of the pull rods or both pull rods at the same time. When not in use, the nut 14 can be turned in the opposite direction to quickly separate the two suitcases, and the flap 7 is turned to insert the flap 7 into the square groove 6, and the suitcases can be used normally. When the suitcase is used alone, the flap 7 is lowered so that the flap 7 is in a horizontal state, and a tablet computer, a mobile phone, a lunch box, etc. can be placed on the flap 7 and used as a table.

[0021] Furthermore, long grooves 15 are respectively provided on both sides of the square groove 6. The long grooves 15 are vertically arranged and higher than the square grooves 6. A baffle rod 16 is installed in the long groove 15. The lower end of the baffle rod 16 is rotatably installed in the long groove 15 through an upper rotating shaft. The baffle rod 16 can be switched between a horizontal state and a vertical state by rotating the upper rotating shaft. The baffle rod 16 is embedded in the long groove 15 in the vertical state. A connecting tube 17 is sleeved on the baffle rod 16. The baffle rod 16 is provided with an external thread. The inner wall of the connecting tube 17 is provided with an internal thread matching the external thread. The function of the baffle rod 16 is to further improve the safety of children when riding on the flap 7 of the suitcase. When two suitcases are spliced, the baffle rods 16 in the horizontal state are relatively close to each other. Any connecting tube 17 is rotated to make the connecting tube 17 move on two opposite baffle rods 16. The two baffle rods 16 are connected to form a guardrail under the action of the connecting tube 17. The state of the two suitcases after splicing is as follows. Figure 3 shown.

[0022] Furthermore, a support block 18 is provided below the square groove 6, and after the flap 7 is rotated so that the flap 7 is in a horizontal state, the support block 18 supports the flap 7. The support block 18 improves the stability of the flap 7 in a horizontal state.

[0023] Furthermore, the four corners of the side 5 of the body 1 opposite to the front cover 2 are respectively provided with protrusions 19, and the height of the protrusions 19 is equal to the height of the support blocks 18. When a single suitcase is laid flat, the protrusions 19 and the support blocks 18 form a support foot, and the items in the suitcase can be taken out by opening the front cover 2.

[0024] Furthermore, the upper end of the blocking rod 16 is clamped with the long groove 15 , and the upper bottom sides of the flap 7 are clamped with the square groove 6 .

[0025] Furthermore, a hand buckle portion 20 is provided at the upper end of the long groove 15 and the middle of the upper end of the square groove 6 respectively, so as to facilitate the removal of the blocking rod 16 or the flap 7 from the long groove 15 or the square groove 6 .

[0026] Furthermore, the notch 11 includes a front stop surface 21 close to the upper bottom edge 8 and a rear stop surface 22 opposite to the front stop surface 21. The threaded hole is located on the front stop surface 21, and the threaded hole forms a docking interface on the upper bottom edge 8. When the nut 14 is rotated so that the front end of the screw 13 extends out of the docking interface when the nut 14 is close to the front stop surface 21, and when the nut 14 is rotated in the opposite direction so that the front end of the screw 13 is located in the threaded hole when the nut 14 is close to the rear stop surface 22. In this way, the screw 13 cannot be removed from the threaded hole, thereby preventing the screw 13 from being lost. The connection process of the screw 13 is as follows: Figure 4 and Figure 5 In order to facilitate the screw rod 13 to be screwed into the corresponding threaded hole of another suitcase, the docking port can be designed to be trumpet-shaped for easy centering.

[0027] Furthermore, the surface of the connecting pipe 17 is elastic.

[0028] It is worth mentioning that the technical features such as the pull rod 3, the front cover 2, the universal wheel 4, etc. involved in the patent application of the present invention should be regarded as the prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and should not be regarded as the inventive point of the patent of the present invention. The patent of the present invention will not be further elaborated.

[0029] The preferred specific embodiments of the present invention are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the existing technology should be within the scope of protection determined by the claims.
