[0002] Plastic storage boxes are a common type of storage container, widely used in homes, offices, factories, and other places to store various items such as clothing, toys, documents, and tools.

[0003] Traditional plastic storage boxes typically have a flat-bottomed structure, which is convenient for stacking. However, moving them, especially when they are filled with heavy items, becomes very difficult and strenuous. To address this issue, some storage boxes with wheels on the bottom have appeared on the market. However, when the boxes are stationary, especially on smooth surfaces, they are prone to sliding due to external forces, resulting in poor stability and safety hazards. When multiple boxes need to be stacked, the protruding wheels can make the upper boxes unstable, affecting stacking stability and space utilization. Therefore, a new type of plastic storage box is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] A type of plastic storage box, such as Figures 1-6 As shown, the device includes a plastic box body 1, with an inner groove 6 at the bottom of the plastic box body 1. A rotating shaft 7 is rotatably installed at the bottom of the box body, and two sets of rollers 8 are fixed to the side wall of the rotating shaft 7. The rollers 8 are located in the inner groove 6, which is used to store the rollers 8.

[0026] Both ends of the rotating shaft 7 are rotatably mounted with limiting seats 11. The two sets of limiting seats 11 are respectively snapped onto the two sides of the plastic box 1. Both ends of the recessed groove 6 are provided with inclined upward arc grooves 9. Both ends of the rotating shaft 7 slide in the two sets of arc grooves 9 respectively. An elastic support component is slidably mounted on the lower end of the plastic box 1. The upper end of the elastic support component is located in the arc groove 9. The rotating shaft 7 and the elastic support component are pressed together.

[0027] The roller 8 can be raised or lowered by sliding the pivot 7 within the upward-sloping arc-shaped groove 9. When movement is required, the pivot 7 is at the bottom of the arc-shaped groove 9, the roller 8 descends and protrudes from the bottom of the box, and the pivot 7 is positioned by inserting the limiting seat 11 into the side wall of the plastic box body 1. The box can then be easily moved by rotating the roller 8 and the pivot 7, saving time and effort. When the box needs to be placed still, the pivot 7 slides to the top of the arc-shaped groove 9, the roller 8 rises and is completely retracted into the recessed groove 6 at the bottom of the box, and the pivot 7 is positioned by inserting the limiting seat 11 into the side wall of the plastic box body 1. The bottom plane of the box is in stable contact with the ground or other boxes, effectively preventing accidental sliding, ensuring high safety, and making it suitable for stacking.

[0028] Multiple rectangular slots 10 are provided on both sides of the plastic box 1. An insertion port 12 is provided on the limiting seat 11. The insertion port 12 is the same size as the rectangular slot 10. Elastic fixing components are fixedly connected to both sides of the plastic box 1. One side of the elastic fixing component passes through the slot and the end is inserted into the rectangular slot 10 to fix the limiting seat 11.

[0029] When the rotating shaft 7 moves, the limiting seat 11 moves accordingly. After the rotating shaft 7 is in position, the elastic fixing component inserts into the slot and the rectangular slot 10, so that the limiting seat 11 is fixed on the side wall of the plastic box 1 and cannot be rotated or moved, thus preventing the rotating shaft 7 from moving automatically.

[0030] Multiple rectangular grooves 10 are located above the arc groove 9. The elastic fixing component includes a connecting plate 13. Multiple sets of plugs 14 are fixed to one side of the connecting plate 13. The multiple sets of plugs 14 are respectively plugged into the multiple sets of rectangular grooves 10, and the plugs 14 are plugged into the sockets 12.

[0031] Since the limiting seat 11 always faces upward, the rectangular groove 10 needs to be above the arc groove 9 to facilitate the installation of the limiting seat 11. To slide the rotating shaft 7 and the limiting seat 11, the connecting plate 13 needs to be pulled to disengage the insert 14 from the socket 12 and the rectangular groove 10. After adjusting the position of the rotating shaft 7, the insert 14 is inserted into the socket 12 and the rectangular groove 10 to position the limiting seat 11.

[0032] A spring 15 is fixedly connected to one side of the connecting plate 13. The end of the spring 15 is fixedly connected to the side wall of the plastic box 1. The spring 15 is in a stretched state to prevent the insert block 14 from dislodging from the rectangular groove 10.

[0033] Spring 15 is always in a stretched state, pulling the connecting plate 13 to prevent the insert 14 on the connecting plate 13 from accidentally detaching from the plastic box 1.

[0034] The bottom of the plastic box 1 is provided with a sliding groove 16, which is connected to the arc groove 9. The elastic support component includes a sliding seat 17, one end of which is slidably installed in the sliding groove 16. The rotating shaft 7 is pressed and engaged with the upper end of the sliding seat 17, and the lower end of the sliding seat 17 is in contact with the ground. The inside of the plastic box 1 is provided with a cavity 18, and a second spring 19 is fixedly connected in the cavity 18. The end of the second spring 19 is fixedly connected to the sliding seat 17.

[0035] When the rotating shaft 7 slides to the upper end of the arc groove 9, the rotating shaft 7 presses against the sliding seat 17, causing the sliding seat 17 to descend. This increases the friction between the plastic box 1 and the ground, and also supports the plastic box 1 to a certain height. When the rotating shaft 7 moves to the bottom of the arc groove 9, the sliding seat 17 is released from the pressure, and the spring 19 pulls the sliding seat 17, causing it to rise and preventing the sliding seat 17 from contacting the ground and causing friction that affects sliding.

[0036] A lid 2 is snapped onto the upper end of the plastic box body 1. A groove 3 is provided on the upper end of the lid 2. A telescopic rod 4 is rotatably installed in the groove 3. A handle 5 is fixed to the end of the telescopic rod 4.

[0037] The lid 2 is sealed and snapped onto the upper end of the plastic box 1. When moving the plastic storage box, pull the handle 5 and extend the telescopic rod 4 to facilitate dragging the plastic box 1. When the plastic storage box does not need to be moved, retract the telescopic rod 4 and store the telescopic rod 4 and the handle 5 in the groove 3 for easy storage of the handle 5.

[0038] The working principle of the plastic storage box provided by this utility model is as follows:

[0039] When movement is required, the pivot 7 is located at the bottom of the arc-shaped groove 9, the roller 8 descends and protrudes from the bottom of the box, and the limiting seat 11 is inserted into the side wall of the plastic box 1 to position the pivot 7. The box can be easily moved by rotating the roller 8 and the pivot 7, saving time and effort. When it needs to be placed still, the pivot 7 slides to the upper end of the arc-shaped groove 9, the roller 8 rises and is completely stored in the recessed groove 6 at the bottom of the box, and the limiting seat 11 is inserted into the side wall of the plastic box 1 to position the pivot 7. The bottom plane of the box is in stable contact with the ground or other boxes, effectively preventing accidental sliding, ensuring high safety, and making it suitable for stacking.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
