DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes the present utility model in conjunction with embodiments.

[0021] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement to the method of the present utility model under the premise of the concept of the present utility model belongs to the scope of protection required by the present utility model.

[0022] Please refer to Figures 1-3 , the present utility model provides a carton convenient for transportation, including a box body 1, fixed columns 2 and a moving component 3. There are four fixed columns 2, and the four fixed columns 2 are respectively fixedly connected to the four corners of the box body 1. The fixed columns 2 can support and reinforce the four corners of the box body 1. A box cover 11 is provided on the top of the box body 1. Plug-in blocks 12 are fixedly connected to the four corners of the bottom surface of the box cover 11. By setting the plug-in blocks 12, when the box cover 11 is closed, the plug-in blocks 12 will be inserted into the upper ends of the fixed columns 2 for clamping. Concave handles 13 are provided on both sides of the box body 1. By setting the concave handles 13, when the goods in the box body 1 are lighter or the box is empty, it is convenient to manually carry the box body 1.

[0023] Refer to Figure 3 , the moving component 3 is arranged in the fixed column 2. The moving component 3 includes a support plate 31, a screw rod 32, a support block 33, a universal wheel 34 and a driving component 35. The support plate 31 is fixedly connected in the fixed column 2. The screw rod 32 is rotatably installed on the support plate 31. The support block 33 is sleeved on the lower end of the screw rod 32 and is threadedly connected to the screw rod 32. The support block 33 is slidably attached to the inner wall of the fixed column 2. The universal wheel 34 is rotatably installed at the bottom of the support block 33. The driving component 35 is connected to the upper end of the screw rod 32. By setting the moving component 3, when the goods in the box body 1 are heavier, the driving component 35 can be used to rotate the screw rod 32, so that the screw rod 32 drives the support block 33 to descend along the fixed column 2, so that the support block 33 drives the universal wheel 34 to extend out from the lower end of the fixed column 2 and contact the ground, so that the universal wheel 34 can be used to conveniently move the box body 1, reducing the labor of manual handling and facilitating handling.

[0024] Specifically, the driving component 35 includes a knob 351, a worm 352 and a worm gear 353. The knob 351 is arranged on the side wall of the fixed column 2 and is fixedly connected to the worm 352. The worm 352 is rotatably installed in the fixed column 2. The worm gear 353 is fixedly connected to the upper end of the screw rod 32 and meshes with the worm 352. By setting the driving component 35, only by rotating the knob 351, the knob 351 drives the worm 352 to rotate, the worm 352 drives the worm gear 353 to rotate, and the worm gear 353 drives the screw rod 32 to rotate, the adjustment of the universal wheel 34 can be completed, and the operation is convenient.

[0025] Further, an annular groove 311 is formed inside the support plate 31, and a limiting ring 321 is provided on the surface of the screw rod 32. The limiting ring 321 slides in the annular groove 311. Through the cooperation of the annular groove 311 and the limiting ring 321, the screw rod 32 can be limited, so that the screw rod 32 maintains relatively stable sliding with the support plate 31. The lower end of the screw rod 32 extends into the support block 33 and is fixedly connected with a limiting block 322. By providing the limiting block 322, the support block 33 can be prevented from detaching from the lower end of the screw rod 32.

[0026] The working principle and usage process of the present utility model are as follows: First, by setting the moving component 3, when the goods in the box body 1 are heavy, only need to rotate the knob 351, so that the knob 351 drives the worm 352 to rotate, the worm 352 drives the worm wheel 353 to rotate, the worm wheel 353 drives the screw rod 32 to rotate, the screw rod 32 drives the support block 33 to descend along the fixed column 2, and the support block 33 drives the universal wheel 34 to extend out from the lower end of the fixed column 2 and contact the ground. Thus, the box body 1 can be conveniently moved by using the universal wheel 34, reducing the labor of manual handling and facilitating the handling.

[0027] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
