Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a packaging box that is not easily bent. Background Technology

[0002] Packaging boxes play an important role in daily life and industrial production, typically used to protect, store, and display various products. However, traditional packaging boxes often have design and structural flaws, making them susceptible to bending or deformation during transportation and use. This not only affects the aesthetics of the packaging box but may also damage the internal products, causing economic losses to consumers and manufacturers. Patent publication number CN115180289A discloses a novel packaging box, including a packaging box body and a rotating sealing cap. The inner side of the packaging box body is provided with a rope winding component, on which a rope is connected. One end of the rope is fixedly connected to the rope winding component. The rope winding component includes a winding wheel fixed disc and a winding wheel movable disc, with the movable disc mounted on the winding wheel fixed disc. One end of the rope in this invention is connected to the inside of the rotating sealing cap, and the other end is fixedly connected to the rope winding component. On the one hand, the rotating sealing cap can be subjected to force, so that the rotating sealing cap can automatically seal the packaging box body under the action of the rope. On the other hand, it stores force on the rigid spring. After releasing, the rigid spring returns to its original shape under the action of elastic potential energy, and the rope is retracted. After use, the rigid spring pulls the rope to automatically snap the rotating sealing cap onto the packaging box body, thereby improving the sealing performance and safety of the packaging box body.

[0003] In the above solutions, the box structure does not have an anti-bending design. Traditional box shells cannot effectively disperse local impact forces, making them prone to bending. Secondly, sealing the box during handling can prevent items from falling and reduce bending caused by impacts from internal items. Therefore, this utility model proposes a packaging box that is not easily bent to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0005] The present invention adopts the following technical solution: a packaging box that is not easily bent, comprising a box body, a cover plate and a locking mechanism, wherein the cover plate is disposed on the left and right sides of the top of the box body, the cover plate is rotatably connected to the box body by a hinge, and the locking mechanism is fixedly installed on the cover plate.

[0006] Preferably, the number of the cover plates is set to two.

[0007] Preferably, the housing includes an outer panel, reinforcing ribs, and an inner panel, wherein the outer panel is fixedly connected to the inner panel via the reinforcing ribs.

[0008] Preferably, the reinforcing rib includes a front pin and a rear pin, the front pin is fixedly connected to the outer plate, the rear pin is fixedly connected to the inner plate, and the front pin and the rear pin are fixedly connected in an arc shape towards one side.

[0009] Preferably, the locking mechanism includes a mounting base, on which a rotating block is provided, and locking blocks are provided on the left and right sides of the rotating block. The rotating block is fixedly connected to one side of the locking block through an elastic block, and a driving rotating ring is fixedly connected to the other side of the locking block. The driving rotating ring cooperates with the outer locking rotating ring.

[0010] Preferably, the mounting base is provided with a matching slider, and the rotating block is provided with a sliding groove, and the rotating block is slidably connected to the mounting base through the matching slider.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting the box body to be composed of an outer plate, reinforcing ribs and an inner plate, when the box body is subjected to external impact, the outer plate transmits the local stress to the rear pin through the front pin. The front pin and the rear pin deform at the same time, absorbing part of the stress. The remaining stress continues to be transmitted to the inner plate through the rear pin. At the same time, the inner plate transmits the local stress to the entire crushed surface. This energy absorption method can effectively reduce the bending resistance of the packaging box.

[0013] 2. In this utility model, by setting a method in which the locking block squeezes the driving rotating ring and the locking rotating ring to engage, when it is necessary to lock the box, the driving rotating ring drives the locking rotating ring to rotate to the other side cover plate to achieve the locking effect. After the locking is completed, the external force is removed, and the locking block will drive the driving rotating ring to disengage from the locking rotating ring under the action of the elastic block, preventing the locking and unlocking caused by accidental contact during transportation, thus improving the stability of the system.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1

[0025] Please see Figure 1-6This utility model provides a technical solution: a packaging box that is not easily bent, comprising a box body 1, a cover plate 3, and a locking mechanism 4. The cover plate 3 is disposed on the left and right sides of the top of the box body 1, and is rotatably connected to the box body 1 via hinges 2. The locking mechanism 4 is fixedly installed on the cover plate 3. There are two cover plates 3. The box body 1 includes an outer plate 11, a reinforcing rib 12, and an inner plate 13. The outer plate 11 is fixedly connected to the inner plate 13 via the reinforcing rib 12. The reinforcing rib 12 includes a front pin 121 and a rear pin 122. Pin 121 is fixedly connected to the outer plate 11, and the rear pin 122 is fixedly connected to the inner plate 13. The front pin 121 and the rear pin 122 are fixedly connected in an arc shape to one side. The housing 1 is configured with a structure composed of an outer plate 11, a reinforcing rib 12, and an inner plate 13. When the housing 1 is subjected to an external impact, the outer plate 11 transmits the local stress to the rear pin 122 through the front pin 121. The front pin 121 and the rear pin 122 deform simultaneously, absorbing part of the stress, and the remaining stress continues to be transmitted through the rear pin 122. The inner plate 13 is guided to absorb local stress, which in turn transmits the stress to the entire compressed surface. This method effectively reduces the bending resistance of the packaging box. The box body 1 is the main body of the packaging box, used to contain and protect the contents. The cover plate 3 is located on the left and right sides of the top of the box body 1 to close the opening of the box body 1. It is rotatably connected to the box body 1 by the hinge 2, so that the cover plate 3 can be easily opened and closed. There are two of them, located on the left and right sides of the box body 1, which enhances the sealing and stability of the packaging box. The hinge 2 connects the cover plate 3 and the box body 1, allowing the cover plate 3 to rotate around a certain axis, providing the degree of freedom of movement required for the cover plate 3 to open and close. The outer plate 11 and the inner plate 13 are located on the inner and outer sides of the box body 1, respectively, providing basic structural support. The reinforcing rib 12 connects the outer plate 11 and the inner plate 13, increasing the strength and rigidity of the box body 1 and preventing it from bending and deforming. The front pin 121 and the rear pin 122 of the reinforcing rib 12 are fixedly connected inward in an arc shape, further enhancing the integrity and stability of the box body 1.

[0026] Example 2

[0027] Please see Figure 1-4The locking mechanism 4 includes a mounting base 41, on which a rotating block 42 is mounted. Locking blocks 43 are located on both sides of the rotating block 42. The rotating block 42 is fixedly connected to one side of the locking block 43 via an elastic block 44. A driving ring 47 is fixedly connected to the other side of the locking block 43. The driving ring 47 engages with an outer locking ring 48. A sliding block 45 is mounted on the mounting base 41. A groove 46 is formed on the rotating block 42. The rotating block 42 is slidably connected to the mounting base 41 via the sliding block 45. The locking mechanism is designed so that the locking block 43 presses the driving ring 47 and the locking ring 48 into contact. When it is necessary to lock the housing 1, the driving ring 47 drives the locking ring 48 to rotate onto the other side cover plate 3, achieving the locking effect. After completion, the external force is removed, and the locking block 43, under the action of the elastic block 44, will drive the drive ring 47 to disengage from the locking ring 48, preventing accidental locking and unlocking during transportation and improving the stability of the system. By rotating the drive ring 47, the locking block 43 can be engaged or disengaged from the outer locking ring 48, thereby realizing the locking and unlocking functions. The elastic block 44 connects the rotating block 42 and the locking block 43, providing the elastic restoring force of the locking mechanism 4 during the locking and unlocking process, ensuring the reliability and stability of the locking mechanism 4. Together with the slider 45 and the slide groove 46, the rotating block 42 can slide on the mounting base 41, providing the required degree of freedom of movement for the locking mechanism 4 during operation.

[0028] Working principle: When locking the packaging box, push the locking block 43 to both sides with two fingers to overcome the contraction force of the elastic block 44. The locking block 43 pushes the drive ring 47 to engage with the locking ring 48. By manually rotating the locking block 43, the rotating block 42 is driven to rotate along the slide groove 46 relative to the mounting base 41 to complete the locking. The unlocking process is the reverse operation.

[0029] When the packaging box is subjected to external pressure, the outer plate 11 transmits the local stress to the rear pin 122 through the front pin 121. The front pin 121 and the rear pin 122 deform simultaneously to absorb part of the stress. The remaining stress continues to be transmitted to the inner plate 13 through the rear pin 122. At the same time, the inner plate 13 transmits the local stress to the entire pressure-bearing surface. The reinforcing ribs 12 on the pressure-bearing surface deform to different degrees to absorb the remaining stress.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
