[0003] Referring to patent document CN2020213880994, which discloses a die-cast aluminum box for an LED display screen with a handle, the box comprises: a power supply box, a frame, a cross rib, a handle, a lock, and a buckle. The cross rib is disposed within the frame of the frame and is fixedly connected to the frame. The power supply box is fixedly mounted on the cross rib. The frame is provided with a lock and a buckle. During assembly, the lock of one frame is fixedly connected to the buckle of the other frame. The handle is mounted on the frame. The power supply box comprises an upper shell, a lower shell, and a power block. The lower shell is fixedly mounted on the cross rib. The upper shell is connected to the lower shell by a buckle. The power block is placed in a cavity formed by the upper and lower shells. The upper surface of the upper shell is provided with heat dissipation ribs. The upper shell of the box is fixed to the cross rib of the box by a buckle connection. This buckle connection method has the problem of being unstable. During the assembly of the power component, it is easy for the shell to not be fully buckled. When replacing or repairing the power component, it is also easy for the buckle to break, resulting in a short service life. Summary of the Invention

The power supply shell cover is arranged on the power supply base; a plurality of first mounting ears arranged at intervals are extended outward from the outer peripheral side surface of the power supply base, and a plurality of second mounting ears arranged at intervals and corresponding to the first mounting ears are extended outward from the outer peripheral side surface of the power supply shell. The second mounting ears are provided with countersunk holes, and the fastening screws are threadedly connected to the first mounting ears after passing through the countersunk holes.

[0006] Wherein, the first mounting ear is provided with a threaded hole.

[0007] Wherein, the upper side and the lower side of each connecting rib both extend outwards to form a first supporting portion.

[0008] The first supporting portion extends downward to form a first protrusion.

[0009] Wherein, the inner peripheral side surfaces of the frame all extend inwardly to form a second supporting portion.

[0010] The second supporting portion extends downward to form a second protrusion.

[0011] Wherein, handles are formed on the left and right sides of the frame respectively.

[0012] The handle is arranged to be tilted upward.

[0013] The handle is provided with a through hole for inserting a hand, and the hole wall of the through hole is provided with a plurality of grooves arranged at intervals.

[0014] Compared with the prior art, the embodiment of the present invention has the following beneficial effects: the power supply housing is fixedly assembled by screw fastening, replacing the previous snap connection method, which is safer and more secure, and solves the problem of loose installation in the past.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] This utility model discloses a specific implementation of an LED display box, please see Figures 1 to 4 , including a frame 1, a power supply shell 21 and multiple fastening screws (not shown). A power supply base 2 arranged longitudinally is formed in the middle of the frame 1, and connecting ribs 11 extend from the left and right sides of the power supply base 2 toward the inner wall of the frame 1.

[0024] As an improvement, the power supply housing 21 is mounted on the power supply base 2. To enhance safety, multiple first mounting ears 23 are extended outward from the outer peripheral side of the power supply base 2. Multiple second mounting ears 22 are extended outward from the outer peripheral side of the power supply housing 21. The second mounting ears 22 are provided with countersunk holes 24, through which fastening screws pass and are threadedly connected to the first mounting ears 23. It should be noted that the first mounting ears 23 do not need to have holes, and the fastening screws can be self-tapping screws, which are threadedly connected to the first mounting ears 23. If self-tapping screws are not used for the fastening screws, the first mounting ears 23 can optionally be provided with threaded holes, which can be threadedly connected to the fastening screws through the threaded holes to achieve the same tightening effect.

[0025] As another improvement, to better support the LED module, first supporting portions 31 extend outward from the upper and lower sides of each connecting rib 11. These first supporting portions 31 extend downwardly to form first bosses 33, which are primarily designed to engage with the positioning holes of the LED module to better position the module. Similarly, second supporting portions 32 extend inward from the inner circumference of the frame 1. These second bosses 34 extend downwardly to form second bosses 34, which function similarly to the first bosses 33.

[0026] To facilitate the movement and carrying of the frame 1, handles 4 are formed on the left and right sides of the frame 1. As a preferred solution, the handles 4 are tilted upward, which is more ergonomic and easier to handle. Furthermore, the handles 4 have a through hole for inserting a hand. The wall of the through hole is provided with multiple spaced grooves 41. The grooves 41 are designed to fit the fingers of a hand, making it more comfortable to hold. Furthermore, the bottom of the grooves 41 can be provided with multiple spaced bumps to prevent slipping.

[0027] Compared with the prior art, the power supply housing 21 of the box of this embodiment is fixedly assembled by screw fastening, replacing the previous snap connection method, which is safer and more secure to install, and solves the problem of loose installation in the past.

[0028] Finally, it should be noted that the 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.
