Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box technology, specifically to an adaptive folding packaging box structure. Background Technology
[0002] Plastic packaging boxes are widely used, primarily for storing machinery, electronics, and other products, or semi-finished products in the production process. Traditionally, packaging boxes are broadly categorized by material: cardboard, wood, and hard plastic. Cardboard boxes are susceptible to moisture and are relatively expensive; wooden boxes are heavy, inconvenient to handle, and excessive logging can cause environmental damage, hindering sustainable development. Therefore, plastic packaging boxes are currently the most commonly used material.
[0003] However, existing plastic packaging boxes also have some problems in use. For example, the shape of existing plastic packaging boxes is fixed. When they are not in use, they take up a lot of space when stored. In addition, existing plastic packaging boxes are usually of fixed volume, which is not convenient to expand the capacity for loading as needed, and their practicality is poor. Utility Model Content
[0004] The purpose of this invention is to provide an adaptive folding packaging box structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adaptive folding packaging box structure, comprising: A base plate has connecting seats fixedly bonded to its top walls at both ends. A first side plate is hinged to the top of each of the two connecting seats. A second side plate is hinged to the top walls at both the front and rear ends of the base plate. A first expansion plate is hinged to the top of each of the two first side plates, and a second expansion plate is hinged to the top of each of the two second side plates. A locking frame is provided at the top of each of the first side plates. Four pairs of insertion posts are fixedly bonded to the bottom wall of the locking frame. A pair of first insertion slots are provided on the top walls of both the first and second side plates. The first insertion slots are adapted to the insertion posts, and the insertion posts are movably inserted into the first insertion slots.
[0006] Preferably, the top wall of the locking frame has two symmetrically arranged grooves, and a locking bolt is provided in the groove. The top walls of the two first side plates are each provided with a first threaded groove, and the locking bolt is threaded into the first threaded groove.
[0007] Preferably, a second threaded groove is provided in the middle of the bottom wall of each of the two first expansion plates, and the second threaded groove is adapted to the locking bolt.
[0008] Preferably, the bottom walls of both the first expansion plate and the second expansion plate are provided with a second insertion groove that is compatible with the insertion post.
[0009] Preferably, a first magnetic block is installed on the outer wall of both the first side plate and the second side plate, and a second magnetic block that is magnetically attracted to the first magnetic block is installed on the inner wall of both the first expansion plate and the second expansion plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are: The first and second side panels of this utility model can be folded inwards to the top wall of the bottom plate when not in use, thus facilitating folding and storage and reducing space occupation. With the first expansion plate provided on the first side panel and the second expansion plate provided on the second side panel, when expansion is needed, the first expansion plate can be folded to the top side of the first side panel and the second expansion plate can be folded to the top side of the second side panel. Then, the first and second expansion plates are locked by the insertion of the plug on the locking frame and the second plug slot, thereby facilitating the expansion of the packaging box and making the loading capacity of the packaging box adjustable, which greatly improves the practicality of the packaging box.

[0013] 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.
[0014] Please see Figure 1-4 This utility model provides a technical solution: an adaptive folding packaging box structure, comprising: A base plate 1 has connecting seats 2 fixedly bonded to the top walls at both ends. A first side plate 3 is hinged to the top of each of the two connecting seats 2. A second side plate 4 is hinged to the top walls at both ends of the base plate 1. A first expansion plate 5 is hinged to the top of each of the two first side plates 3. A second expansion plate 6 is hinged to the top of each of the two second side plates 4. A locking frame 7 is provided at the top of each of the first side plates 3. Four pairs of insertion posts 8 are fixedly bonded to the bottom wall of the locking frame 7. A pair of first insertion slots 9 are provided on the top walls of both first side plates 3 and both second side plates 4. The first insertion slots 9 are adapted to the insertion posts 8, and the insertion posts 8 are movably inserted into the first insertion slots 9.
[0015] The top wall of the locking frame 7 has two symmetrically arranged grooves 10, and a locking bolt 11 is provided in the groove 10. The top walls of the two first side plates 3 are each provided with a first threaded groove 12. The locking bolt 11 is threaded into the first threaded groove 12. By the cooperation of the locking bolt 11 and the first threaded groove 12, the locking frame 7 can be easily locked and fixed to the top of the two first side plates 3.
[0016] A second threaded groove 13 is provided in the middle of the bottom wall of each of the two first expansion plates 5. The second threaded groove 13 is adapted to the locking bolt 11. The second threaded groove 13 can lock the locking frame 7 onto the first expansion plate 5 by the cooperation of the locking bolt 11 and the second threaded groove 13 after the first expansion plate 5 is flipped up.
[0017] The bottom walls of the first expansion plate 5 and the second expansion plate 6 are each provided with a second insertion groove 14 that is adapted to the insertion post 8. The second insertion groove 14 facilitates the first expansion plate 5 and the second expansion plate 6 to be fixed in place by the insertion of the insertion post 8 and the second insertion groove 14 after the first expansion plate 5 and the second expansion plate 6 are flipped up.
[0018] A first magnetic block 15 is installed on the outer wall of the first side plate 3 and the second side plate 4. A second magnetic block 16 that is magnetically attracted to the first magnetic block 15 is installed on the inner wall of the first expansion plate 5 and the second expansion plate 6. By magnetically attracting the first magnetic block 15 and the second magnetic block 16, the first expansion plate 5 and the second expansion plate 6 can be easily fixed on the first side plate 3 and the second side plate 4 respectively when not in use.
[0019] Working principle: The first side plate 3 and the second side plate 4 of this utility model can be folded inward to the top wall of the bottom plate 1 when not in use, so as to facilitate folding and storage when not in use and reduce the space occupied. With the first expansion plate 5 provided on the first side plate 3 and the second expansion plate 6 provided on the second side plate 4, when expansion is required, the first expansion plate 5 is folded to the top side of the first side plate 3 and the second expansion plate 6 is folded to the top side of the second side plate 4. Then, the first expansion plate 5 and the second expansion plate 6 are limited and locked by the insertion of the insertion post 8 on the locking frame 7 and the second insertion slot 14, so as to facilitate the expansion of the packaging box, making the loading capacity of the packaging box adjustable and greatly improving the practicality of the packaging box.
