A display screen packaging box

Abstract

This application provides a display screen packaging box, relating to the field of display screen packaging boxes. It includes a box body with two packaging lids fixedly connected to its upper surface. The display screen body is housed inside the box body, and a lower pad is also provided inside. A limiting component is provided on the upper surface of the lower pad. This application, through the cooperation of a handle, a first flexible cardboard, a rigid cardboard, a second flexible cardboard, a flexible bending cardboard, a rotating plate, a fixing plate, and a torsion spring, enables the side panels to bend into a triangular support structure when the box body is placed on the ground. Due to the non-deformable geometric stability of a triangle, the support range of the box can be extended from the bottom four corners to the triangular areas on both sides, increasing the contact area with the ground, lowering the overall center of gravity, effectively preventing tipping due to uneven ground or minor collisions, and significantly reducing the risk of damage to the display screen caused by tipping.

Description

Technical Field

[0001] This utility model relates to the field of display screen packaging boxes, and more specifically, to a display screen packaging box. Background Technology

[0002] Liquid crystal displays (LCDs) are a type of display used in digital clocks and many portable computers. They consist of two polarized materials and a liquid crystal solution placed between them. LCDs have become the mainstream of information products due to their advantages such as low power consumption, small size and low radiation, providing users with the best visual environment.

[0003] As precision electronic devices, displays require packaging that simultaneously meets the needs of transportation protection and storage stability. Currently, most mainstream display packaging boxes use a rectangular paper or plastic structure, employing internal cushioning components (such as foam and bubble wrap) to protect the display from impacts. However, in actual use, the support points of the rectangular structure are concentrated only at the bottom four corners. When the packaging box containing the display is slightly uneven in the warehouse or subjected to minor external impacts, it is prone to tipping over due to a shift in the center of gravity, causing pressure and damage to the display inside, resulting in scratches on the exterior or damage to internal components. This increases transportation and storage costs and demonstrates poor stability in actual use. Therefore, we propose a new display packaging box to address these issues. Utility Model Content

[0004] The purpose of this invention is to solve the problem that some display screen packaging boxes are not very stable when placed and are prone to tipping over due to a shift in the center of gravity.

[0005] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a display screen packaging box, including a packaging box body. Two packaging covers are fixedly connected to the upper surface of the packaging box body. A display screen body is disposed inside the packaging box body, and a lower pad is disposed inside the packaging box body. A limiting component is disposed on the upper surface of the lower pad. A C-shaped connecting cardboard is fixedly connected to the front surface of the packaging box body. A rigid cardboard is disposed inside the C-shaped connecting cardboard. A first flexible cardboard and a second flexible cardboard are fixedly connected to both ends of the rigid cardboard, respectively. A handle is fixedly connected to the upper end of the first flexible cardboard, and a flexible bending cardboard is fixedly connected to the lower end of the second flexible cardboard. The flexible bending cardboard is fixedly connected to the packaging box body. Reset components are disposed on both sides of the packaging box body.

[0006] As a preferred technical solution of this application, the reset assembly includes two fixing plates, both of which are fixedly connected to the front surface of the packaging box body. The two fixing plates are respectively located on both sides of the flexible bent cardboard. A rotating plate is provided between the two fixing plates. Rotating shafts are fixedly connected to both sides of the rotating plate. The rotating plate is rotatably connected to the fixing plates on both sides through the rotating shafts on both sides.

[0007] As a preferred technical solution of this application, torsion springs are fixedly connected between the two sides of the rotating plate and the adjacent side of the two fixed plates, and the two torsion springs are respectively movably sleeved on the outside of the rotating shaft.

[0008] As a preferred technical solution of this application, the end of the rotating plate away from the fixed plate is provided with an arc-shaped contact plate.

[0009] As a preferred technical solution of this application, the limiting component includes two lower partitions, both of which are fixedly connected to the surface of the lower pad. The interior of the packaging box body is provided with two upper partitions, and a first groove is formed on the adjacent side surface of the two lower partitions and the two upper partitions.

[0010] As a preferred technical solution of this application, the display screen body is located between the upper and lower partition blocks, and the display screen body is located inside the first groove.

[0011] As a preferred technical solution of this application, the interior of the packaging box body is provided with two lower protective edges and two upper protective edges. The two lower protective edges are fixedly connected to the lower pad. A second groove is provided on the adjacent side surface of the two lower protective edges and the two upper protective edges. The display screen body is also located inside the second groove.

[0012] As a preferred technical solution of this application, four paper corner protectors are fixedly connected inside the packaging box body, and packing straps are provided on the outside of the packaging box body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. Through the coordination of the handle, first flexible cardboard, hard cardboard, second flexible cardboard, flexible bending cardboard, rotating plate, fixed plate and torsion spring, the side panels can be bent to form a triangular support structure when the packaging box is placed on the ground. Since the triangle has the geometric stability of being non-deformable, the support range of the packaging box can be extended from the four corners at the bottom to the triangular areas on both sides, increasing the contact area with the ground, lowering the overall center of gravity, effectively avoiding tipping caused by uneven ground or slight collisions, and greatly reducing the risk of damage to the display screen caused by tipping.

[0016] 2. The coordination between the lower pad, lower middle partition, upper middle partition, lower guard ridge, and upper guard ridge further improves the stability of the internal display screen body, effectively preventing collisions between display screen bodies and enhancing the protective effect.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A display screen packaging box includes a box body 1. Two packaging covers 2 for sealing the box body 1 are fixedly connected to the upper surface of the box body 1. Several display screen bodies 3 are disposed inside the box body 1. A lower pad 14 is disposed inside the box body 1, and a limiting component is disposed on the upper surface of the lower pad 14. The structures on both sides of the box body 1 are identical; therefore, the following description focuses on the front side of the box body 1. Several U-shaped connecting cardboard 4 are fixedly connected to the front surface of the box body 1. Hard cardboard 5 is disposed inside the U-shaped connecting cardboard 4. 5 can move vertically inside the C-shaped connecting cardboard 4, and the C-shaped connecting cardboard 4 can restrict the movement trajectory of the cardboard 5. The two ends of the cardboard 5 are respectively fixedly connected to the first flexible cardboard 6 and the second flexible cardboard 7. The upper end of the first flexible cardboard 6 is fixedly connected to the handle 23, and the lower end of the second flexible cardboard 7 is fixedly connected to the flexible bending cardboard 8. The flexible bending cardboard 8 is fixedly connected to the packaging box body 1. Both sides of the packaging box body 1 are provided with reset components. Since the reset components on both sides have the same structure, the following description will focus on the front reset component.

[0030] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the reset assembly includes two fixing plates 9, both of which are fixedly connected to the front surface of the packaging box body 1. The two fixing plates 9 are located on both sides of the flexible bent cardboard 8, and a rotating plate 10 is provided between the two fixing plates 9. Rotating shafts 11 are fixedly connected to both sides of the rotating plate 10, and the rotating plate 10 is rotatably connected to the fixing plates 9 on both sides through the rotating shafts 11 on both sides.

[0031] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, torsion springs 12 are fixedly connected between the two sides of the rotating plate 10 and the adjacent side of the two fixed plates 9. The two torsion springs 12 are respectively movably sleeved on the outside of the rotating shaft 11. When the user lifts the packaging box body 1 through the handle 23, the packaging box body 1 will move downward due to its own weight. Then, the handle 23 will drive the first flexible cardboard 6, the hard cardboard 5 and the second flexible cardboard 7 to move, and limit them through the C-shaped connecting cardboard 4. At the same time, the second flexible cardboard 7 will drive the flexible bending cardboard 8 to rotate. At this time, the flexible bending cardboard 8 will drive the rotating plate 10 to rotate between the two fixed plates 9, and the torsion springs 12 will produce elastic deformation. After the handle 23 is no longer subjected to external force, the rotating plate 10 can be reset by the elastic force of the torsion spring 12 itself. Thus, when the rotating plate 10 rotates, it forces the second flexible cardboard 7 to bend. Finally, the cooperation of the flexible bending cardboard 8, the second flexible cardboard 7 and the rotating plate 10 forms a triangular support structure, thereby improving the stability of the packaging box body 1 when placed.

[0032] In the above embodiments, when the packaging box body 1 is lifted and transported, the triangular support structures on both sides automatically retract, reducing the overall volume of the packaging box body 1 and the side protrusions, avoiding the side panels from snagging on other items during transport, and improving the ease of transport; when the packaging box body 1 is placed on the ground, the triangular structure formed by the bending on both sides does not require additional assembly and can be quickly switched to a stable state, adapting to various scenarios such as temporary storage, and the operation is simple and efficient.

[0033] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, an arc-shaped contact plate 13 is provided at the end of the rotating plate 10 away from the fixed plate 9. The arc-shaped contact plate 13 further reduces the friction between the rotating plate 10 and the second flexible paperboard 7, and also effectively prevents the rotating plate 10 from damaging the second flexible paperboard 7.

[0034] Example 2

[0035] The display packaging box provided in Example 1 is further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the limiting component includes two lower partitions 15, both of which are fixedly connected to the surface of the lower pad 14. The inside of the packaging box body 1 is provided with two upper partitions 17. The two lower partitions 15 and the two upper partitions 17 are provided with a first groove 16 on the side surface that is close to each other.

[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the display body 3 is located between the upper partition block 17 and the lower partition block 15, and the display body 3 is located inside the first groove 16.

[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the interior of the packaging box body 1 is provided with two lower guard ribs 18 and two upper guard ribs 20. The two lower guard ribs 18 are fixedly connected to the lower pad plate 14. The two lower guard ribs 18 and the two upper guard ribs 20 are provided with a second groove 19 on their adjacent side surfaces. The display body 3 is also located inside the second groove 19. Through the cooperation between the lower middle partition block 15, the upper middle partition block 17, the lower guard ribs 18 and the upper guard ribs 20, the display body 3 is effectively limited, and the collision between the display bodies 3 during transportation is effectively avoided, further improving the safety of the display body 3.

[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, four paper corner protectors 21 are fixedly connected inside the packaging box body 1. The paper corner protectors 21 effectively prevent the packaging box body 1 from deforming. Packing straps 22 are provided on the outside of the packaging box body 1.

[0039] In the above embodiments, the materials of the packaging box body 1, cardboard 5, first flexible cardboard 6, second flexible cardboard 7, flexible bending cardboard 8, and handle 23 are all known technologies in the art. Since they are not the main structures of this solution, they will not be described in detail here.

[0040] The usage process of the display screen packaging box provided by this utility model is as follows:

[0041] First, the lower pad 14 and paper corner protectors 21 are placed inside the packaging box body 1. Then, the display screen body 3 is placed inside the first groove 16 and the second groove 19. Subsequently, the upper partition block 17 and the upper guard 20 are clipped onto the outside of the display screen body 3. Then, the packaging cover 2 is sealed and encapsulated with tape or other objects, thereby achieving the encapsulation of the packaging box body 1. Finally, the packing strap 22 is placed on the outside of the packaging box body 1 for secondary fixation to ensure the sealing effect.

[0042] When it is necessary to move the packaging box body 1, the user lifts the packaging box body 1 through the handle 23. At this time, the packaging box body 1 will move downward due to its own weight and the weight of the internal display screen body 3. Then the handle 23 will drive the first flexible cardboard 6, the hard cardboard 5 and the second flexible cardboard 7 to move. During the movement, the cardboard 4 of the U-shaped connecting cardboard will limit the movement. At the same time, the second flexible cardboard 7 will drive the flexible bending cardboard 8 to rotate. At this time, the flexible bending cardboard 8 will drive the rotating plate 10 to rotate between the two fixed plates 9, and the torsion spring 12 will produce elastic deformation.

[0043] When the packaging box body 1 is placed, once the handle 23 is no longer subjected to external force, the rotating plate 10 can be reset by the elastic force of the torsion spring 12 itself. This forces the second flexible cardboard 7 to bend when the rotating plate 10 rotates, ultimately achieving a triangular support structure formed by the flexible bending cardboard 8, the second flexible cardboard 7, and the rotating plate 10, thereby improving the stability of the packaging box body 1 when placed.
