[0006] A reinforced ball pack is provided on the outer side of the enclosure formed by the first fixing plate, the second fixing plate, and the third fixing plate;
[0007] The overall structure also includes fastening and reinforcement structures.
[0008] Preferably, the first and second fixing plates are provided with first fastening holes, and bolts are installed in the first fastening holes to fix them to the side of the box; the third fixing plate is provided with a second fastening hole, and bolts are installed in the second fastening hole to fix it to the bottom or top corner of the box. The first and second fastening holes form a fastening structure.
[0009] Preferably, a reinforcing ring is provided around the first fastening hole, the reinforcing ring enhancing the structural strength of the first fastening hole area.
[0010] Preferably, a protrusion is provided on the outer side of the second fixing plate. The protrusion increases the impact resistance of the corner, and the reinforcing ring and the protrusion form a reinforcing structure.
[0011] Preferably, the first fixing plate and the second fixing plate are further provided with arc-shaped grooves.
[0012] This utility model has at least the following beneficial effects:
[0013] When the corner of the cover is subjected to an external impact, the reinforced ball pack first contacts the force and disperses the impact. The reinforced ball pack enhances the fit and reinforcement effect between the corner and the edge of the casing, while also acting as a buffer upon impact. The curved groove allows for some cushioning deformation of the corner. Simultaneously, the reinforcing ring ensures the structural strength of the first fastening hole, and the protrusion increases the corner's impact resistance. When the corner is subjected to an external impact, the protrusion disperses the impact force, while the curved groove reduces the overall weight of the corner and increases its flexibility, providing some buffering deformation space upon impact.

[0018] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0019] Please refer to Figure 1 As shown in the embodiment of this utility model, a box body reinforcement corner protection includes an integral structure. The integral structure includes a fixing plate 100, a fixing plate 201, and a fixing plate 300. The fixing plate 100 and the fixing plate 201 are set at a 90-degree angle to fit the corners of two adjacent sides of the box body. The fixing plate 300 is connected below the fixing plate 100 and the fixing plate 201 to reinforce the bottom or top corners of the box body. The included angle between the fixing plate 300 and the fixing plate 100 and the fixing plate 201 is 90 degrees.
[0020] A reinforcing ball pack 300 is provided on the outer side formed by the fixing plate 100, fixing plate 201 and fixing plate 300. The reinforcing ball pack 300 can further enhance the fit between the corner and the corner of the box and the reinforcement effect, and at the same time play a buffering role when it is impacted.
[0021] The overall structure also includes fastening and reinforcement structures.
[0022] The first fastening hole 110 is provided on the first fixing plate 100 and the second fixing plate 101. Bolts are installed in the first fastening hole 110 to fix it to the side of the box. The second fastening hole 210 is provided on the third fixing plate 200. Bolts are installed in the second fastening hole 210 to fix it to the bottom or top corner of the box. The first fastening hole 110 and the second fastening hole 210 form a fastening structure to enhance the installation stability.
[0023] A reinforcing ring 120 is provided around the first fastening hole 110. The reinforcing ring 120 enhances the structural strength of the first fastening hole 110 and prevents cracking or other issues from occurring around the first fastening hole 110 during the installation and use of the fastening components.
[0024] A protrusion 130 is provided on the outer side of the fixing plate 2 101. The protrusion 130 increases the impact resistance of the corner. When the corner is hit by an external force, the protrusion 130 can disperse the impact force. The reinforcing ring 120 and the protrusion 130 form a reinforcing structure.
[0025] The fixing plate 100 and fixing plate 2 101 are also provided with arc-shaped grooves 140. The arc-shaped grooves 140 can reduce the overall weight of the corner wrap and increase the flexibility of the corner wrap, providing a certain buffer deformation space when subjected to impact.
[0026] Installation process: Attach the first fixing plate 100 and the second fixing plate 101 to the two adjacent side corners of the enclosure, and attach the third fixing plate 200 to the bottom corner of the enclosure. Then, use bolts or other fasteners to secure the corners to the side of the enclosure through the first fastening hole 110, and further secure them from the bottom of the enclosure through the second fastening hole 210 to ensure the corners are firmly installed.
[0027] Usage: During use, when the corner of the enclosure is impacted by external force, the reinforcing ball pad 300 first contacts the external force and disperses the impact. The reinforcing ball pad 300 enhances the fit and reinforcement effect between the corner and the enclosure's edges, while also acting as a buffer upon impact. The arc-shaped groove 140 allows the corner to undergo a certain degree of cushioning deformation. Simultaneously, the reinforcing ring 120 ensures the structural strength of the first fastening hole 110, and the protrusion 130 increases the corner's impact resistance. When the corner is impacted by external force, the protrusion 130 disperses the impact force, and the arc-shaped groove 140 reduces the overall weight of the corner while increasing its flexibility, providing some buffering deformation space upon impact.
