Description

Technical Field

[0001] This utility model relates to the field of plastic box technology, and in particular to a stackable transparent plastic storage box. Background Technology

[0002] Plastic boxes are transparent folding boxes, cylinders, hinged boxes, tote bags, hanging tags, and other plastic products made of materials such as PVC and PET. They are plastic containers used for packaging and storing goods, and feature enhanced user experience, durable packaging, moisture resistance, waterproofing, high toughness, strong transportation safety, and improved product quality. Stackable plastic boxes can be stacked vertically to save space and facilitate the storage and transportation of goods.

[0003] Although existing stackable transparent plastic storage boxes are mostly assembled by stacking, which is convenient and quick, improper human placement of the plastic boxes during stacking can cause them to slide under external force, leading to misalignment and tilting. This results in an unbalanced stack, making them prone to collapse after being bumped during transportation, thus causing instability and reduced safety. Utility Model Content

[0004] The purpose of this invention is to provide a stackable transparent plastic storage box to solve the problem that existing storage boxes are prone to tilting and tipping over when stacked.

[0005] To achieve the above objectives, a stackable transparent plastic storage box is provided, comprising: a storage box body, a cover plate at the upper end of the storage box body, two slots on the upper surface of the cover plate, positioning holes through the cover plate at both ends of the two slots, insertion holes at the four corners of the upper surface of the cover plate, insertion rods fixedly connected to the four corners of the lower end of the storage box body, crossbars fixedly connected at intervals on the lower surface of the storage box body, positioning grooves on the outer side of the storage box body, positioning blocks inside the positioning grooves, and mounting plates fixedly connected to the outer side of the positioning blocks.

[0006] According to the aforementioned stackable transparent plastic storage box, both the mounting plate and the positioning block are L-shaped, and the mounting plate is installed on the outside of the two stacked storage boxes.

[0007] According to the aforementioned stackable transparent plastic storage box, a first spring is provided inside both ends of the crossbar, a first limiting plate is provided at the front end of the first spring, and a positioning rod is fixedly connected to the side wall of the first limiting plate.

[0008] According to the aforementioned stackable transparent plastic storage box, sleeves are provided at the four corners of the lower end of the storage box body. A movable rod is slidably connected inside the sleeve, and a knob is threadedly connected to the outside of the movable rod. A pressure plate is fixedly connected to the lower end of the movable rod.

[0009] According to the stackable transparent plastic storage box, a second spring is provided inside the sleeve, and a second limiting plate is fixedly connected to the lower end of the second spring. The lower surface of the second limiting plate is fixedly connected to the upper end of the movable rod.

[0010] According to the aforementioned stackable transparent plastic storage box, a locking block is provided between the storage box body and the cover plate, and handles are provided on both sides of the storage box body.

[0011] According to the aforementioned stackable transparent plastic storage box, two adjacent positioning slots are respectively disposed on the upper and lower halves of the outer side of the stacked storage box.

[0012] According to the stackable transparent plastic storage box, the upper surface of the knob is tightly fitted to the lower end of the sleeve.

[0013] The above-mentioned solution has the following beneficial effects: This utility model features a slot on the upper surface of the cover plate and a locking block on the lower surface. It utilizes a positioning rod and a positioning hole, as well as an insertion rod and an insertion hole, to ensure the stability of the stacked storage boxes and prevent them from tipping over. Additionally, sleeves and movable rods are installed at the four corners of the bottom storage box to cooperate with it. By adjusting the height of the movable rods, the storage box can be kept stable, preventing instability when placed. This facilitates the handling of the stacked storage boxes by workers and prevents them from tipping over.

[0018] Reference Figure 1-6 This utility model discloses a stackable transparent plastic storage box, comprising: a storage box body 1, a cover plate 2 at the upper end of the storage box body 1, two slots 6 on the upper surface of the cover plate 2, the slots 6 cooperating with crossbars 11 to position the stacked storage box bodies 1, keeping them stable and preventing tilting, positioning holes 4 penetrating through the cover plate 2 at both ends of the two slots 6, positioning rods 8 cooperating with the positioning holes 4 to position the stacked storage boxes and prevent misalignment, insertion holes 5 at the four corners of the upper surface of the cover plate 2, and insertion rods 10 fixedly connected to the four corners of the lower end of the storage box body 1 for better positioning of the storage box body 1, crossbars 11 fixedly connected at intervals on the lower surface of the storage box body 1, positioning grooves 9 on the outer side of the storage box body 1, positioning blocks 17 inside the positioning grooves 9, mounting plates 16 fixedly connected to the outer side of the positioning blocks 17, and mounting plates 16 installed on the outer side between two adjacent storage box bodies 1 after stacking, the positioning blocks 17 cooperating with the positioning grooves 9 to ensure the stability of the two connected storage box bodies 1 after stacking.

[0019] Both the mounting plate 16 and the positioning block 17 are L-shaped. The mounting plate 16 is installed on the outside of the two stacked storage boxes. A first spring 12 is installed inside both ends of the crossbar 11, allowing the storage box body 1 to automatically push the positioning rod 8 after stacking, so that the positioning rod 8 passes through the center of the positioning hole 4. A first limiting plate 13 is installed at the front end of the first spring 12, and the positioning rod 8 is fixedly connected to the side wall of the first limiting plate 13. Sleeves 14 are installed at the four corners of the lower end of the storage box body 1. A movable rod 21 is slidably connected inside the sleeve 14, and a knob 20 is threadedly connected to the outside of the movable rod 21. The friction between the outside of the knob 20 and the lower end of the sleeve 14 is used to position the movable rod 21, keeping the storage box body 1 stable and preventing tilting. A pressure plate 15 is fixedly connected to the lower end of the movable rod 21. A second spring 18 is installed inside the cylinder 14. The elasticity of the second spring 18 automatically pushes the movable rod 21 to move, which facilitates the adjustment of the stability of the storage box body 1.
