Description

Technical Field

[0001] This utility model relates to the field of anti-drop technology for flat packaging boxes, specifically a corner structure of a flat packaging box with anti-drop function. Background Technology

[0002] In today's electronic device market, tablet computers have gained popularity among consumers due to their portability, versatility, and powerful processing capabilities. As tablet sales continue to rise, the safety of their transportation and storage processes has become increasingly important. As the first line of defense for protecting tablets, the design of the packaging box is crucial, especially the corner structure of the packaging box, which plays a key role in drop protection.

[0003] Most existing packaging boxes have a relatively conventional structural design, often using simple cardboard folding. During the transportation and handling of flatbeds, the corners of the packaging box are easily damaged first in the event of a drop or collision. Because traditional packaging boxes lack targeted anti-drop reinforcement design at the corners, they cannot effectively disperse and buffer the impact force when subjected to external impacts. This leads to a serious risk of damage to the flatbed inside the packaging box. When the packaging box is dropped from a certain height, the impact force on the corners will be concentrated instantly, which may cause the corners of the flatbed to be bumped, scratched, or even damaged internal components due to vibration. For precision electronic devices such as flatbeds, even minor corner damage may have an adverse effect on their performance, thereby reducing the lifespan of the flatbed and the user experience. In actual transportation, flatbeds undergo multiple loading, unloading, stacking, and bumps under different road conditions, all of which increase the probability of the corners of the packaging box being hit. Therefore, we propose a corner structure for flatbed packaging boxes with anti-drop function. Utility Model Content

The magnetic connection between the magnetic blocks 17 and the magnetic blocks 7 facilitates opening the box. The set of sponge blocks 18 at the bottom of the rotating cover 3 can effectively provide shock absorption and drop protection for the top of the tablet body 4.

[0033] Furthermore, the anti-drop corner assembly includes anti-drop corners 2 and elastic elements 13. The anti-drop corners 2 are provided with three elastic elements 13 that are spatially perpendicular to each other, and the elastic elements 13 are distributed in the same direction as the edges of the packaging box 1. The anti-drop corner assembly can provide efficient shock absorption and anti-drop protection for the eight corners of the packaging box 1, effectively absorb the impact force caused by falling, reduce the impact force transmitted to the inside of the packaging box 1, and provide all-round protection.

[0034] Furthermore, the outer side of the anti-fall corner 2 is provided with three rubber blocks 9 that are spatially perpendicular to each other.

It is magnetically attracted to magnetic block 217 on the rotating cover 3, which facilitates the closing of the rotating cover 3 and protects the flat plate body 4.

[0044] Connection hole 18: There are three connection holes 18 on the eight corners of the outer side of the packaging box 1, which are arranged vertically in space. They are connected to the connection hole 211 of the anti-drop corner 2 by the matching screw to fix the anti-drop corner 2.

[0045] Rubber block 9: Rubber block 9 is distributed vertically in three spaces outside the anti-fall corner 2. It has a rubber ring 10 on the outside and an inner cavity 12 to place an elastic element 13 to absorb the impact force of the collision.

[0046] Rubber rings 10: Rubber rings 10 are evenly distributed on the outside of rubber block 9 to increase the friction between the anti-fall corner 2 and the outside world, reduce slippage during collision, and provide auxiliary protection;

[0047] Connection hole 2 11: Connection hole 2 11 is opened between adjacent rubber blocks 9 on the outside of the anti-drop corner 2, and is connected to connection hole 1 8 of the packaging box 1 by an adapter screw to realize the installation of the anti-drop corner 2;

[0048] Inner cavity 12: The inner cavity 12 has a rectangular frame structure and is opened inside the rubber block 9. It is used to place the elastic element 13, provide the elastic element 13 with room to move, and work together to buffer the impact force.

[0049] Elastic element 13: The elastic element 13 consists of three equally spaced mating plates 15, which are installed in the inner cavity 12 of the anti-fall corner 2. It absorbs the impact force through elastic deformation, and the mating plates 15 support the inner cavity 12.

[0054] Sponge block 18: Sponge blocks 18 are evenly distributed at the bottom of the rotating cover 3 and fit against the top of the tablet body 4, providing shock absorption and drop protection for the tablet 4 at the top.

[0055] Working Principle: Following the diagram, correctly install the corner structure of the anti-drop flat packaging box. When the anti-drop flat packaging box encounters impacts such as drops or collisions, its corner structure will work together through multiple protective mechanisms to protect the flat body 4. First, the anti-drop corners 2 on the eight outer corners of the packaging box 1 serve as the first line of defense. Three rubber blocks 9, spatially perpendicular to each other, with their good elasticity, can contact external objects at the moment of impact, initially absorbing and dispersing the impact force. Simultaneously, the equidistantly distributed rubber rings 10 on the outside of the rubber blocks 9 further increase friction, reducing the risk of secondary collisions caused by slippage. The inner cavity 12 inside the rubber blocks 9 houses the elastic element 13, which consists of three equidistantly distributed mating plates 15. The symmetrical mating plates 15, welded to the two ends of the mating plates 15, fit inside the inner cavity 12. When the impact force is transmitted to the rubber blocks 9, the elastic element 13 undergoes elastic deformation, and the mating plates 15... While supporting the inner cavity 12, it converts the impact force into its own elastic potential energy, further buffering the external force. The anti-drop corner 2 is connected to the corner connection hole 8 of the packaging box 1 through the second connection hole 11 and is securely installed on the packaging box 1 with an adapter screw, ensuring that the entire anti-drop corner assembly functions reliably. In addition, the inflatable card cavity 6 inside the packaging box 1 is interference-fitted with the tablet body 4. When impacted, the air bladder on the side wall and bottom of the inflatable card cavity 6 continuously buffers the impact force through the compression and expansion of the gas, and can be adjusted according to the size and shape of the tablet body 4 to provide a tight fit and protection. The rotating cover 3 is rotated with the connecting rod 5 through the rotating hole 16 on the side, making it easy to open and close. The magnetic block 17 on its top is magnetically attracted to the magnetic block 7 on the top of the packaging box 1 to ensure a tight closure. At the same time, the sponge block 18 at the bottom of the rotating cover 3 is attached to the top of the tablet body 4 to provide shock absorption protection at the top. Multiple protections work together to protect the tablet body 4 in all directions.
