[0030] A drop-proof trolley case, such as Figure 1 and Figure 3 As shown, it includes a main box body 1 with an opening on the top surface, two upper end flaps 2 hinged on both sides of the opening on the top surface of the main box body 1, a plurality of universal wheels 6 are fixedly connected to the bottom surface of the main box body 1, a turning handle 3 is hinged on the upper end flap 2, and the two upper end flaps 2 are detachably connected. Specifically, a buckle sub-component 4 and a buckle mother component 5 are fixedly connected to the two upper end flaps 2, and the two upper end flaps 2 are detachably connected through the buckle sub-component 4 and the buckle mother component 5.

[0031] Both sides of the main box body 1 are provided with a pull rod assembly, the length of the pull rod assembly is adjustable, and the telescopic end of the pull rod assembly can be detachably connected to the upper end flip cover 2.

[0032] like Figure 2 and Figure 4 As shown, the pull rod assembly includes an outer rod 7 fixedly connected to the side of the main box body 1 through a connecting seat 8 and with the length direction consistent with the main box body 1, an inner rod 10, and a handle 13 fixedly connected to the end of the inner rod 10. The outer rod 7 is hollow, and the inner rod 10 is slidably connected to the outer rod 7. The inner rod 10 can be detachably connected to the upper end flip cover 2.

[0033] Specifically, a fastener is detachably connected to the handle 13. The outer ring of the inner rod 10 is provided with a through hole 11 which passes through it and is arranged toward the upper end flip cover 2. The opening of the through hole 11 is provided with a rounded corner 12. After the fastener passes through the through hole 11, it is detachably connected to the upper end flip cover 2. The fastener includes a connecting bolt 16. The screw head of the connecting bolt 16 is provided with a cross groove 17. The upper end flip cover 2 is provided with a threaded groove 9 which can be coaxially arranged with the through hole 11. The stud of the connecting bolt 16 can pass through the through hole. 11 is threadedly connected with the thread groove 9, the outer ring of the screw head of the connecting bolt 16 is provided with a hole for passing it through, and a rotating shaft 18 is rotatably connected in the hole. Both ends of the rotating shaft 18 are fixedly connected with a connecting piece 19 that can be deflected to the outer ring of the screw head of the connecting bolt 16. A sink groove 14 is provided on the end surface of the handle 13, and a threaded groove 15 is provided in the sink groove 14.

[0034] When the utility model is actually in use, people only need to flip the upper flap 2 so that the upper flaps 2 on both sides can be closed, and the opening on the top surface of the main box body 1 is opened. Then, the upper flaps 2 on both sides are detachably connected through the buckle sub-component 4 and the buckle mother component 5. Normally, people can carry the trolley case by turning the handle 3.

[0035] If people need to pull the suitcase, they only need to hold the handle 13, and then make the inner rod 10 and the outer rod 7 of the pull rod assembly move relative to each other, so that the available length of the pull rod assembly is increased, so that people can hold the handle 13 and then drag the suitcase to move using the universal wheel 6;

[0036] If the suitcase needs to be checked or stored, people can adjust the tie rod assembly to a suitable length, insert the matching tool (screwdriver) into the cross slot 17, and then remove the connecting bolt 16 from the recessed groove 14 and the threaded groove 15. If there is no matching tool, people can also manually use their fingernails to move the connecting piece 19, so that the connecting piece 19 rotates in the hole through the rotating shaft 18, and then people can pinch the connecting piece 19 and transmit the force through the rotating shaft 18, so that the connecting bolt 16 can be withdrawn from the recessed groove 14 and the threaded groove 15.

[0037] After that, after aligning the through hole 11 and the thread groove 9, people pass the connecting bolt 16 through the through hole 11 under the guidance of the rounded corner 12, so that the connecting bolt 16 can be threadedly connected with the thread groove 9, and then the length of the pull rod assembly is fixed, so that the pull rod assemblies on both sides can serve as external skeletons to protect the main box body 1 and the upper end flap 2, to prevent the pull rod box from falling or bumping and causing damage during the check-in or storage process.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
