Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cardboard box technology, and specifically relates to a quick-folding cardboard box. Background Technology
[0002] Cardboard boxes are packaging containers made from paper pulp, typically constructed from multiple layers of cardboard (such as corrugated paper or kraft paper) through bonding or stapling processes. Their main functions include protecting goods from damage during transport, facilitating storage and stacking, enhancing the appearance of goods, and conveying brand information. They are considered environmentally friendly packaging materials. Folding cardboard boxes, a type of green packaging container using cardboard as the base material, are primarily used for packaging pharmaceuticals, food, and daily necessities. They are characterized by low cost, convenient storage and transportation, and recyclability.
[0003] While existing cardboard boxes have multiple creases that allow them to be folded, they cannot secure the folded boxes. Folded boxes may lack stability and are prone to collapsing or deforming during transportation or storage, leading to damage to goods or improper stacking. Therefore, we propose a quick-folding cardboard box. Utility Model Content
[0004] The purpose of this invention is to provide a quick-folding cardboard box to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-folding cardboard box, including a base plate, with first side plates symmetrically connected to both ends of the base plate; firstly, first inner layer plates symmetrically connected to both sides of the first side plates; a slot is formed through the surface of the first inner layer plate; secondly, second inner layer plates symmetrically connected to both sides of the first side plates; a locking block is fixedly connected to one end of the second inner layer plate; the locking block and the slot are interlocked; and second side plates are symmetrically connected to both sides of the base plate.
[0006] Preferably, a second folding plate is connected to one side of each of the second side plates, a reinforcing plate is connected to one side of each of the second folding plates, and a third folding plate is connected to one side of each of the reinforcing plates.
[0007] Preferably, a first folding plate is connected to one side of the first side plate, a connecting plate is provided in the middle of one side of the first folding plate, and card plates are symmetrically connected to both sides of the connecting plate.
[0008] Preferably, the surface of the first side plate is provided with a built-in handle.
[0009] Preferably, the surface of the base plate is coated with a waterproof layer.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting the first side plate, connecting plate, second inner layer plate, first inner layer plate and reinforcing plate, the carton has the strength of a double-layer structure and the effect of quick folding.
[0011] 2. The third folding plate is bent and inserted into the gap between the bottom end of the first inner layer plate and the second inner layer plate and the surface of the bottom plate, thereby achieving the function of wrapping the first inner layer plate and the second inner layer plate. According to the spacing between the two symmetrically set reinforcing plates, the clamping plate is bent to a suitable angle, so that the connecting plate is bent to the inside of the two reinforcing plates, which increases the strength of the device structure and the stability of the connection.

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-3 This utility model provides a technical solution: a quick-folding carton, including a base plate 1, with first side plates 2 symmetrically connected to both ends of the base plate 1, and first inner layer plates 7 symmetrically connected to both sides of the first side plates 2. A slot 8 is formed through the surface of the first inner layer plate 7, and second inner layer plates 9 symmetrically connected to both sides of the first side plates 2. A locking block 10 is fixedly connected to one end of the second inner layer plate 9, and the locking block 10 and the slot 8 are locked together. Second side plates 11 are symmetrically connected to both sides of the base plate 1.
[0016] Specifically, a second folding plate 12 is connected to one side of the second side plate 11, a reinforcing plate 13 is connected to one side of the second folding plate 12, and a third folding plate 14 is connected to one side of the reinforcing plate 13.
[0017] Specifically, a first folding plate 4 is connected to one side of the first side plate 2, a connecting plate 5 is provided in the middle of one side of the first folding plate 4, and a clamping plate 6 is symmetrically connected to both sides of the connecting plate 5.
[0018] Specifically, the surface of the first side panel 2 is provided with built-in handles 3.
[0019] Specifically, the surface of the base plate 1 is coated with a waterproof layer 15.
[0020] In this embodiment, the first side plates 2, symmetrically arranged on both sides of the base plate 1, are first bent upwards. Then, the first inner layer plate 7 and the second inner layer plate 9 are fixed together by the locking block 10 and the locking groove 8. Next, the second side plates 11 on both sides of the base plate 1 are bent upwards so that they fit against the outer sides of the first inner layer plate 7 and the second inner layer plate 9. Then, the reinforcing plate 13 is bent to the inner side of the first inner layer plate 7 and the second inner layer plate 9. Finally, the third folding plate 14 is bent and inserted into the gap between the bottom end of the first inner layer plate 7 and the second inner layer plate 9 and the surface of the base plate 1, thereby achieving the function of wrapping the first inner layer plate 7 and the second inner layer plate 9, increasing the strength and stability of the device structure. At this time, the connecting plate 5 is bent. According to the distance between the two symmetrically arranged reinforcing plates 13, the locking plate 6 is bent to a suitable angle so that the connecting plate 5 is bent to the inner side of the two reinforcing plates 13 and parallel to the inner side of the first side plate 2, thereby completing the rapid folding effect of the device. The waterproof layer 15 increases the waterproof effect of the base plate 1. The built-in handle 3 makes it easy to carry and move the device.
