Thus, through the above-mentioned structure, the installation of the movable pull rod 200 can be completed by rotating and matching the rotating connecting rod 220 with one of the rotating connecting parts 110, and the use angle can be adjusted according to the actual use during use.

[0051] In addition, in order to facilitate the storage of the movable pull rod 200, one side of the box body 100 is provided with a containing groove 112, the containing groove 112 is communicated with the rotating connecting groove 111 and is used for containing the main rod body 210. Thus, through the above-mentioned structure, the movable pull rod 200 can be stored in the containing groove 112, so that the structure size is reduced and the storage or movement is facilitated. In the embodiment, the containing groove 112 is arranged on one of the sides provided with the rotating connecting part 110, that is, the movable pull rod 200 can be stored in the containing groove 112 on the side. In other embodiments of the utility model, the containing groove 112 can also be arranged on each side provided with the rotating connecting part 110.

[0052] It should be further explained that, when the rotating connecting part 110 is configured, the rotating connecting part 110 is arranged as the rotating connecting groove 111 arranged on the box body 100. The purpose of the above-mentioned structure is that the rotating connecting rod 220 can be assembled into the rotating connecting groove 111 for use, so that the structure of the movable connecting rod and the rotating connecting part 110 protruding from the box body 100 is reduced, and the neatness and the appearance of the box body 100 are improved.

[0053] Please refer to Figures 1-7 When the main rod body 210 is configured, the main rod body 210 comprises a handle 211 and an extension rod 212, two ends of the extension rod 212 are connected with the handle 211 and the rotating connecting rod 220 respectively. The height of the extension rod 212 can be adjusted through the extension rod 212, and the handle 211 facilitates the pushing and pulling action of the user.

[0054] On the basis of the above structure with the accommodating groove 112, in order to keep the movable pull rod 200 in the state of being located in the accommodating groove 112 during use, the corresponding structure is arranged to limit the movement of the movable pull rod 200 relative to the accommodating groove 112. Specifically, the abutting part that abuts against the main rod body 210 is arranged in the accommodating groove 112. Such arrangement makes the main rod body 210 of the movable pull rod 200 relatively tightly located in the accommodating groove 112 when cooperating with the accommodating groove 112, thereby avoiding sliding out of the accommodating groove 112. In addition, at least one movable buckle 113 is arranged at the slot opening of the accommodating groove 112. The movable buckle 113 is arranged in a clamped manner with the box body 100. When clamped with the box body 100, the movable buckle 113 spans the slot opening of the accommodating groove 112, and the movable buckle 113 can abut against the main rod body 210 located in the accommodating groove 112, thereby avoiding sliding out of the accommodating groove 112.

[0055] It should be noted that based on the above content, the pull rod box 10 is arranged with the corresponding structure to keep the main rod body 210 of the movable pull rod 200 cooperating with the accommodating groove 112 of the box body 100. Such state makes the main rod body 210 in the storage state be stored in the accommodating groove 112, thereby facilitating the reduction of the structure size and convenient storage and transfer. Moreover, in this state, the movable pull rod 200 is relatively fixed with the box body 100, so that it can be easily pushed. When the main rod body 210 of the movable pull rod 200 is located outside the accommodating groove 112, the movable pull rod 200 can rotate relative to the aforementioned rotating connection part 110. Therefore, the angle can be flexibly adjusted according to the needs at this time, thereby facilitating the pulling.

[0056] Further, please refer to Figures 1-9 In this embodiment, during use, the movable pull rod 200 can be detachably connected with the rotating connection part 110 and can also rotate relative to the rotating connection part 110. Therefore, on the basis of the above structure of the box body 100, at least one end of the rotating link 220 is movably provided with a positioning pin 221, and the rotating connection groove 111 is provided with a positioning hole 114. The positioning pin 221 has a state of extending out of the rotating link 220 and cooperating with the positioning hole 114, and a state of being located in the rotating link 220 and being disengaged from the positioning hole 114.

[0057] Moreover, the rotating link 220 is provided with a mounting hole 222, and the mounting hole 222 is provided with an elastic member 223. The positioning pin 221 is slidably connected with the mounting hole 222 along the axis of the rotating link 220 and abuts against the elastic member 223 in the mounting hole 222. The elastic member 223 is used to make the positioning pin 221 have a tendency to move outwardly from the mounting hole 222.

[0058] Thus, through such a setting mode, the positioning pin 221 can be operated to extend into the mounting hole 222 of the rotating connecting rod 220 against the elastic force of the elastic member 223, so that the rotating connecting rod 220 can move out of or into the rotating connecting groove 111; the positioning pin 221 can also extend out of the rotating connecting rod 220 under the elastic force of the elastic member 223 without external force, and cooperate with the positioning hole 114 in the rotating connecting groove 111, so that the rotating connecting rod 220 can rotate relative to the rotating connecting groove 111, and the rotating connecting rod 220 can also be prevented from sliding out of the rotating connecting groove 111; and in the embodiment, in order to improve the stability of the rotating connection, the positioning pin 221 is arranged at both ends of the rotating connecting rod 220.

[0059] On the basis of the foregoing structure, in order to facilitate the user to adjust the positioning pin 221 so that the positioning pin 221 extends into the mounting hole 222 of the rotating connecting rod 220, a limiting hole 224 in communication with the mounting hole 222 is formed in the side wall of the rotating connecting rod 220, and the positioning pin 221 is provided with a movable tab 225 slidingly fitted with the limiting hole 224; the movable tab 225 is used to drive the positioning pin 221 to move along the axis of the rotating connecting rod 220 relative to the mounting hole 222 under the action of external force, so as to extend out of or into the mounting hole 222. Thus, the user can operate the movable tab 225 during use, that is, by pulling the movable tab 225 to make the positioning pin 221 move into the mounting hole 222 against the elastic force of the elastic member 223, so that the positioning pin 221 can move out of the corresponding positioning hole 114, thereby enabling the positioning pin 221 to disengage from the positioning hole 114, so that it can be conveniently removed, or it can be conveniently installed in the reverse manner of the foregoing steps; thus, through the foregoing structure and setting mode, the movable connecting rod can be conveniently switched between the fitting positions in the plurality of rotating connecting portions 110, so as to improve the use flexibility of the trolley case 10.

[0060] Further, please refer to Figures 1-10, in the above structure, in order to avoid the rotation of the movable pull rod 200 to contact with the ground when it is rotatable relative to the rotating connecting part 110, therefore, the rotating connecting part 110 also includes a limiting table 115 arranged at the slot opening of the rotating connecting slot 111, the limiting table 115 is used to abut with the main rod body 210 or the rotating connecting rod 220 to limit the rotation of the rotating connecting rod 220 relative to the rotating connecting slot 111. That is, in this way, when the movable pull rod 200 is rotatable relative to the rotating connecting part 110, the angle of its rotation towards the ground is limited, so as to avoid the contact with the ground and the occurrence of bruise or scratch; and when the limiting table 115 is arranged, it is located on the side of the movable pull rod 200 towards the ground, so as to abut with the movable pull rod 200, and now the maximum angle of its rotation towards the ground. And on the basis of the rotating connecting part 110 being provided with the limiting table 115, when it abuts with the rotating connecting rod 220 to limit the rotation, a boss 226 abutting with the limiting table 115 can also be arranged on the outer periphery of the rotating connecting rod 220.

[0061] Based on the above content, please refer to Figures 1-10 The box body 100 is provided with the rotating connecting part 110 on both adjacent sides, and one side is provided with the accommodating slot 112 and the movable buckle 113, for example, the use steps of the pull rod box 10 are as follows:

[0062] The movable pull rod 200 cooperates with one of the rotating connecting parts 110, and the main rod body 210 cooperates with the accommodating slot 112 as the initial installation position. In the initial installation position, the movable buckle 113 is clamped, so as to avoid the main rod body 210 from moving out of the accommodating slot 112. At this time, the length of the telescopic rod 212 can be adjusted, and then the position of the handle 211 can be adjusted, so as to facilitate the user to use. In this position, the user can push or pull;

[0063] When the movable buckle 113 is unlocked, the movable pull rod 200 can rotate relative to the box body 100, and then the angle position can be adjusted, so as to conveniently pull. In this way, the occurrence of tilting during pulling can be effectively avoided;

[0064] According to the needs of use, when it is needed to switch to the other side of the rotating connecting part 110 for use, the user can operate the movable tab 225 to drive the positioning pin 221 to disengage from the positioning hole 114 and extend into the mounting hole 222, so as to take it out of the rotating connecting slot 111. After inserting it into the rotating connecting slot 111 of the rotating connecting part 110 on the other side, releasing the movable tab 225, the switching of the movable pull rod 200 can be completed after the positioning pin 221 cooperates with the corresponding positioning hole 114;

[0065] Therefore, through the above structure, the installation position of the movable pull rod 200 and the rotating connection state of the movable pull rod 200 can be switched according to the use requirement, so that the movable pull rod 200 can be used flexibly and conveniently, and the inconvenience in the process of pushing and pulling or the tilting of the box body 100 caused by the fixed position of the pull rod and the box body 100 can be avoided.

[0066] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
