[0002] In public places, in order to enhance the beauty and visual effects of some buildings, LED display screens are installed outside some pillars or spherical buildings. Such LED display screens are composed of multiple curved boxes.

[0003] Refer to the patent document with application number CN2021234224824, which discloses a curved box and a cylindrical LED display screen, wherein connecting piece mounting surfaces are provided at the four right angles on the back of the curved box, and the connecting piece mounting surfaces are set as a plane; when the curved boxes are spliced, the connecting pieces are fixed to the adjacent connecting piece mounting surfaces to connect the adjacent curved boxes together. After this type of curved box is completed and placed for a period of time, it is easy to have low structural strength problems due to the insufficient reinforcement structure of the box itself. The curvature of some curved boxes deviates from that of other curved boxes. It can be understood that some curved boxes have deformed due to their low structural strength, which brings various difficulties to subsequent installation or use. Summary of the Invention

[0010] A plurality of ventilation holes arranged at intervals are provided on the outer peripheral side of the frame.

[0011] Wherein, a wiring groove which is concave downward is formed in the middle of the first longitudinal reinforcement rib.

[0017] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0018] The terms "first," "second," and so on, in the specification and claims of this utility model and the accompanying drawings are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product, or end comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed therein, or may optionally include other steps or elements inherent to such process, method, product, or end.

[0019] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] This utility model discloses a specific implementation of a curved LED display box, see Figures 1 to 2 , including an arc-shaped bottom plate 1. Preferably, the arc-shaped bottom plate 1 is a die-cast aluminum or magnesium alloy structure.

[0021] As an improvement, the outer edge of the arc-shaped bottom plate 1 is provided with a frame 4 extending upward, and a first longitudinal reinforcing rib 21 is formed in the middle part of the arc-shaped bottom plate 1 (the center position between the left and right sides of the frame 4) and is located inside the frame 4 and arranged longitudinally. Two first transverse reinforcing ribs 31 are arranged longitudinally and transversely at intervals between the first longitudinal reinforcing rib 21 and the inner wall of the frame 4 (the left and right sides of the frame 4). The first transverse reinforcing rib 31 is located between the upper and lower sides of the frame 4.

[0022] In this embodiment, a second longitudinal reinforcing rib 22 arranged longitudinally is provided between the first longitudinal reinforcing rib 21 and the frame 4 (the left side or right side of the frame 4). The second longitudinal reinforcing rib 22 is located at the center position between the left side or right side of the frame 4 and the first longitudinal reinforcing rib 21. Four second transverse reinforcing ribs 32 arranged at intervals along the longitudinal direction and transversely are provided between the second longitudinal reinforcing rib 22 and the frame 4 (the left side or right side of the frame 4) and between the second longitudinal reinforcing rib 22 and the first longitudinal reinforcing rib 21. As a preferred solution, each second transverse reinforcing rib 32 is located between two first transverse reinforcing ribs 31 on the same side.

[0023] In this embodiment, the width of the first longitudinal reinforcing rib 21 is greater than the width of the second longitudinal reinforcing rib 22 , and the width of the first transverse reinforcing rib 31 is greater than the width of the second transverse reinforcing rib 32 .

[0024] Compared with the prior art, the box body of this embodiment improves the structural strength of the box body by providing the first longitudinal reinforcing rib 21, the second longitudinal reinforcing rib 22, the first transverse reinforcing rib 31 and the second transverse reinforcing rib 32. Even if it is placed for a long time, the curvature of the arc-shaped bottom plate 1 will not change, which solves the problem of low structural strength in the past. In addition, under the premise of ensuring sufficient structural strength, the width of the second longitudinal reinforcing rib 22 and the second transverse reinforcing rib 32 is reduced, thereby saving consumables, reducing production costs, and thus improving economic benefits.

[0025] Optionally, the second transverse reinforcement rib 32 is provided with a plurality of studs 321 arranged at intervals along the transverse direction and formed on the bottom plate. The threaded columns of traditional boxes are generally formed directly on the bottom plate, and the studs 321 are prone to breakage. However, the studs 321 of this embodiment are formed on the second transverse reinforcement rib 32. The second transverse reinforcement rib 32 can reinforce the structural strength of the studs 321, thereby improving the structural strength of the studs 321 themselves and reducing the occurrence of breakage.

[0026] In this embodiment, the curved bottom plate 1 is provided with a plurality of spaced-apart wiring holes 11. Furthermore, L-shaped connecting blocks 41 are formed at the four corners of the frame 4, each with an insertion hole 411 formed on the outward-facing end face. These L-shaped connecting blocks 41 enhance the structural strength of the frame 4, thereby increasing the structural strength of the four corners of the box, improving its drop resistance, and further extending the life of the box.

[0027] In this embodiment, to facilitate assembly of the frame 4 and the cover, the frame 4 extends upwardly to form a plurality of protrusions 42 spaced apart along the circumference of the frame 4, each of which is provided with a mounting hole 421. Furthermore, to enhance heat dissipation, the outer circumference of the frame 4 is provided with a plurality of spaced apart ventilation holes 43.

[0028] In order to facilitate wiring, a downwardly concave wiring groove 211 is formed in the middle of the first longitudinal reinforcement rib 21. As a preferred solution, the cross-section of the wiring groove 211 is trapezoidal.

[0029] Finally, it should be noted that the curved LED display screen box disclosed in the embodiment of the present invention is only a preferred embodiment of the present invention, which is only used to illustrate the technical solution of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
