DETAILED DESCRIPTION

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show typical embodiments of the present invention. Example

[0031] like Figure 1-Figure 4As shown, the packaging box with a locking function of the utility model comprises a packaging box body 1, a box cover 2, a locking piece 21 and a locking piece 3, wherein the locking piece 3 comprises a mounting seat 31, a movable seat 32 is connected to the inner lower part of the mounting seat 31 through a rotating shaft 36, a connecting shaft 34 runs through the middle of the surface of the movable seat 32, a knob 33 and a gear 35 are respectively installed at both ends of the connecting shaft 34, a rack plate 38 and a stabilizing plate 39 are respectively connected to the bottom of the movable seat 32, a slider 310 is installed on the rack plate 38 and the stabilizing plate 39, a second locking hook 37 is connected to the top of the movable seat 32, and a cutting plate 34 is provided on the locking piece 21. When the lock buckle 3 is in the closed state, the second lock hook 37 is tightly locked with the first lock hook 22 on the lock plate 21, which effectively prevents the package box from being opened without authorization. This design is particularly suitable for occasions where it is necessary to ensure the safety of items and prevent theft. The cutting seam 24 on the lock plate 21 is combined with the first lock hook 22 to form a unique anti-counterfeiting mechanism. When an attempt is made to illegally open the package box, the first lock hook 22 will break at the cutting seam 24, leaving an obvious mark. This design not only enhances the anti-counterfeiting property of the package box, but also provides consumers with a simple method to identify the authenticity.

[0032] See also Figure 1 and Figure 4 The top of the packaging box body 1 is connected to a box cover 2, and the front end of the box cover 2 is connected to a locking piece 21. A first locking hook 22 is fixed to the bottom end of the locking piece 21, and a sticking surface 23 is provided on the back of the locking piece 21. The first locking hook 22 and the second locking hook 37 are arranged opposite to each other, and the first locking hook 22 is fixed to the bottom end of the locking piece 21. This design makes the connection between the first locking hook 22 and the locking piece 21 more stable and not easy to fall off or be damaged. At the same time, the mutual hooking of the first locking hook 22 and the second locking hook 37 forms a reliable locking structure, which ensures the safety of the packaging box. Due to the presence of the sticking surface 23, the locking piece 21 can be conveniently pasted on box covers of different materials and shapes, so that the packaging box with this locking function has strong adaptability and can be widely used in different types of packaging box products.

[0033] See also Figure 2 The inner side of the rack plate 38 is a rack, which is meshed with the gear 35. By rotating the gear 35, the rack plate 38 can be accurately driven to move up and down. This design ensures the accuracy and stability of the transmission, making the operation of the lock more reliable. The transmission method of the rack and the gear is relatively simple and does not require an additional transmission mechanism, which makes the entire lock structure more compact. The compact structure not only reduces the space occupied by the packaging box, but also makes the entire packaging box more beautiful and easy to carry.

[0034] See also Figure 1 and Figure 4The front surfaces of the packaging box body 1 and the box cover 2 are both provided with anti-counterfeiting labels 4. As a special mark, consumers can easily verify the authenticity of the product by scanning, querying, etc., and effectively prevent the emergence of counterfeit and shoddy products. The anti-counterfeiting label usually has a striking design and a unique logo pattern, so that consumers can quickly identify and remember it. When purchasing products, consumers can judge the authenticity of the product based on the anti-counterfeiting label, thereby avoiding purchasing counterfeit and shoddy products. Example

[0035] See also Figure 2 and Figure 3 On the basis of the first embodiment, the utility model provides a technical solution: the back of the movable seat 32 is provided with two vertically arranged and mutually parallel sliding grooves for the sliding of the slider 310. The movable seat 32 slides on the back of the movable seat 32 through the slider 310. The sliding groove provides a clear moving path for the slider 310, ensuring the stability and accuracy of the movable seat 32 during the movement. This guide design reduces the risk of failure caused by offset or shaking during the movement, and improves the reliability of the locking structure. The smooth surface and appropriate size design of the sliding groove enable the slider 310 to slide smoothly therein, reducing friction and resistance, which not only makes the operation easier, but also prolongs the service life of the slider and the movable seat.

[0036] See also Figure 1 The mounting seat 31 is fixed to the front surface of the packaging box body 1, and the mounting seat 31 is slidably connected to the movable seat 32, which ensures the stability of the lock structure. Since the mounting seat is the main supporting part of the lock, its stability directly affects the overall performance of the lock. Therefore, through a firm fixing method, the lock can be effectively prevented from loosening or falling off during use.

[0037] See also Figure 1 The inner side of the front end of the box cover 2 and the outer surface of the packaging box body 1 are both provided with magnets that attract each other. The adsorption force between the magnets enables the box cover 2 to fit tightly on the packaging box body 1, thereby enhancing the sealing performance of the packaging box. This design effectively prevents external dust, moisture or other impurities from entering the interior of the packaging box, and protects the packaged items from contamination and damage. Through the adsorption effect of the magnets, the box cover 2 can automatically align and fit with the packaging box body 1 without the need for additional alignment or fixing steps. This design makes it easier and more convenient for users to close the packaging box, thereby improving operating efficiency.

[0038] During implementation, first, in the closed state of the packaging box, the lock buckle 3 is tightly locked with the lock plate 21. When the consumer needs to open the packaging box, the knob 33 is rotated to rotate the gear 35. The rotation of the gear 35 is transmitted to the movable seat 32 through the rack plate 38, causing the movable seat 32 to move downward. In this process, the movable seat 32 pulls the first lock hook 22 connected to the lock plate 21. Since a cutting seam 24 is provided between the first lock hook and the lock plate, when the pulling force reaches a certain level, the first lock hook 22 will break at the cutting seam 24, thereby realizing the opening of the packaging box. The packaging box is also equipped with an anti-counterfeiting function, and anti-counterfeiting information is printed on the lock plate. Once the lock hook breaks, the consumer can identify the authenticity of the packaging box by checking the anti-counterfeiting information. When the packaging box is closed, corresponding magnet blocks are provided on the inner side of the front surface of the box cover and the outer surface of the packaging box body. When the box cover is close to the packaging box body, the attraction between the magnet blocks will cause the box cover to automatically fit onto the packaging box body to achieve a tight connection.

[0039] The advantages of this technical solution in practical applications include but are not limited to the following:

[0040] 1. By setting the lock buckle and the lock plate, the lock buckle and the lock plate are tightly locked with each other during the production process. When the consumer needs to open it, the lock hook breaks under the action of the cutting seam and cannot be repaired;

[0041] 2. The inner side of the front surface of the box cover and the outer surface of the packaging box body are both provided with corresponding magnet blocks. When the packaging box needs to be closed, the box cover is tightly connected to the packaging box body under the action of the magnet blocks, which is convenient for use.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
