Technical Field

[0001] The utility model relates to the technical field of corrugated paper boxes, in particular to a reusable corrugated paper box. Background Art

[0002] Corrugated boxes are a widely used packaging product. They are made of corrugated cardboard through die-cutting, creasing, nailing or gluing. This type of box has gradually replaced wooden boxes and other transport packaging containers with its superior performance and good processing properties, becoming the main force of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, corrugated boxes also play a role in beautifying and promoting goods. Corrugated boxes are green and environmentally friendly products.

[0003] The current application document with application number (CN202223106478.1) discloses a reusable corrugated cardboard box, including a loading frame, a sealing assembly including corrugated cardboard, a sealing cover and fixing bolts, and buffer assemblies are provided at the four corners of the lower surface of the loading frame. The buffer assembly includes a buffer rod, a buffer seat and a buffer spring, and the protective assembly includes a protective base, a buffer protrusion and a positioning slider. The utility model places the load into the loading frame by arranging the buffer assembly and the protective assembly, and realizes elastic buffering through the buffer spring to reduce the impact force on the loading frame. When vibration occurs during transportation, the buffer rod is positioned and slid in the buffer seat, and the vibration is reduced by the buffer spring, thereby improving the service life. When subjected to external force, a collision occurs between the foreign object and the buffer protrusion, which reduces the impact and vibration caused by the collision, thereby achieving effective protection for the loading frame and the sealing assembly, and is suitable for promotion.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1-7 As shown, this embodiment provides a reusable corrugated box.

[0026] It includes a corrugated cardboard box body 1, both sides of the top of the corrugated cardboard box body 1 are connected to the first flip cover 2, the other two sides of the top of the corrugated cardboard box body 1 are connected to the second flip cover 3, a reinforced support frame 4 is arranged in the corrugated cardboard box body 1, and strip slides 5 are arranged on both sides of the reinforced support frame 4. Under the action of the strip slides 5, the use of the movable support component 6 is facilitated, and a movable support component 6 for top support is arranged in the strip slides 5. Mounting holes 7 are arranged on the front and back sides of the corrugated cardboard box body 1, and an adjustable ventilation component 8 is fixedly connected to the inner side wall of the mounting hole 7. Under the action of the mounting hole 7, the adjustable ventilation component 8 can be positioned and connected to the corrugated cardboard box body 1.

[0027] The movable support assembly 6 includes a return spring 601 fixedly mounted on the inner wall of one side of the strip slide 5, and a sliding connection block 602 is fixedly connected to one end of the return spring 601. The sliding connection block 602 is slidably connected in the strip slide 5, and a U-shaped top support frame 603 is fixedly mounted on the top of the sliding connection block 602. A reinforcing support rod 604 is fixedly connected to the inner side wall of the U-shaped top support frame 603. Under the action of the support rod, the strength of the U-shaped top support frame 603 can be improved. Since the two U-shaped top support frames 603 are arranged in the middle position of the corrugated cardboard box body 1, the possibility of deformation and depression caused by the force on the top of the corrugated cardboard box body 1 is reduced.

[0028] The adjustable ventilation component 8 includes a mounting square frame 801 fixedly connected to the inner wall of the mounting hole 7, a sliding notch is provided on the mounting square frame 801, an air permeability adjustment plate 802 is provided in the sliding notch, a snap lock connecting seat 803 is fixedly connected to the top of the air permeability adjustment plate 802, and there are multiple snap lock connecting seats 803. The outer walls on the front and back sides of the corrugated cardboard box body 1 are fixedly connected with a snap lock body 804, and the fixed end of the snap lock body 804 is sleeved on the snap lock connecting seat 803. The air permeability adjustment plate 802 can move in the sliding notch on the mounting square frame 801. After the air permeability adjustment plate 802 moves, the user can position the fixed end of the snap lock connecting seat 803 on the other snap lock connecting seat 803 above the air permeability adjustment plate 802.

[0029] A waterproof film 9 is provided on the outer side of the corrugated cardboard box body 1, the outer side of the first flip cover plate 2 and the outer side of the second flip cover plate 3. Since the waterproof film 9 is provided on the corrugated cardboard box body 1, the first flip cover plate 2 and the second flip cover plate 3, the waterproof performance is improved, so that the corrugated cardboard box body 1, the first flip cover plate 2 and the second flip cover plate 3 are not easily damaged when exposed to water.

[0030] When the present invention is in use, the user needs to place the articles to be transported and stored in the corrugated cardboard box body 1 first. When placing the articles in the corrugated cardboard box body 1, the user can first move the U-shaped top support frame 603 to one side of the corrugated cardboard box body 1. When the U-shaped top support frame 603 moves, it can drive the sliding connection block 602 to slide in the bar slide 5, and the sliding connection block 602 can squeeze the return spring 601 when sliding. After the U-shaped top support frame 603 moves, it avoids the obstruction of the U-shaped top support frame 603, which makes it inconvenient to place the articles in the corrugated cardboard box body 1. When the user places the articles in the corrugated cardboard box body 1, the sliding connection block 602 and the U-shaped top support frame 603 can be reset under the action of the return spring 601. Then the user can flip the first flip cover plate 2 and the second flip cover plate 3 over and cover them. At this time, the U-shaped top support frame 603 is Under the action of the upper support frame 603, the possibility of the top of the corrugated cardboard box body 1 being subjected to force and causing a dent is reduced, and the overall strength of the utility model is high and it is easy to reuse. If the items placed in the corrugated cardboard box body 1 need to be ventilated, the user can rotate the fixed end of the buckle lock body 804 to release the positioning of the buckle lock connecting seat 803 and the air permeability adjustment plate 802, and then the user can move the air permeability adjustment plate 802 to one side. After the air permeability adjustment plate 802 is moved, a ventilation opening can be generated on the installed square frame 801, and finally the user can fix the fixed end of the buckle lock body 804 on the other buckle lock connecting seat 803 on the air permeability adjustment plate 802. At this time, the air permeability adjustment plate 802 can be fixed. In addition, the user changes the size of the ventilation opening on the installed square frame 801 by moving the distance of the air permeability adjustment plate 802, thereby achieving the effect of adjusting the air permeability.
