[0002] An LED display screen is a flat panel display composed of small LED module panels, and is a device used to display various information such as text, images, videos, and video signals. An LED light-emitting diode is a diode made of a compound of gallium and arsenic, phosphorus, nitrogen, indium, and controls the display mode of semiconductor light-emitting diodes. When electrons and holes recombine, visible light can be radiated, so it can be used to make light-emitting diodes, and can be used as an indicator light in circuits and instruments, or to form text or digital displays. Gallium phosphide arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and indium gallium nitride diodes emit blue light.

[0003] In large-scale occasions, LED display screens are often composed of multiple display screens connected in combination. Therefore, a special installation bottom case for LED display screens is required during installation.

[0004] At present, during the installation of the LED bottom case, most of them are fixedly assembled between multiple bottom cases through multiple bolts, resulting in the need to rely on external tools for assembly, which is relatively cumbersome. Moreover, the bolts and threaded holes are prone to looseness over time, affecting the stability of the bottom case assembly. Therefore, it is necessary to propose an LED bottom case convenient for assembly to solve the above-mentioned problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an LED bottom case convenient for assembly, which has the characteristics of being convenient for assembling the first bottom case and the second bottom case, and achieving stable assembly of the first bottom case and the second bottom case.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an LED bottom case convenient for assembly, including a first bottom case and a second bottom case located on the right side of the first bottom case. Installation cavities are opened on the front end faces of the first bottom case and the second bottom case. Two positioning cylinders are fixedly connected to the right side of the first bottom case. Limiting holes are penetrated and opened on the upper and lower sides of the outer wall of the positioning cylinder. Two fixing cylinders are fixedly connected to the left side of the second bottom case. A positioning plate matching the positioning cylinder is arranged inside the fixing cylinder. A spring is installed between one end of the positioning plate and the inside of the fixing cylinder. Limiting rods matching the limiting holes are installed on the upper and lower sides of the outer wall of the positioning plate. Grooves are opened on the upper and lower sides of the positioning plate. Telescopic springs are installed between the inside of the two grooves and the limiting rods;

[0007] A connecting piece is installed on the rear end face between the first bottom case and the second bottom case. Two grooves are opened on the rear end face of the connecting piece. Reinforcing plates are installed inside the two grooves.

[0008] To stably assemble the first bottom shell and the second bottom shell, as an optimized LED bottom shell for convenient assembly of the present utility model, threaded holes are provided on both the upper and lower sides of the positioning cylinder, and limiting members located outside the limiting rods are provided on both the upper and lower sides of the positioning cylinder.

[0009] To stably install the limiting rod in the limiting hole, as an optimized LED bottom shell for convenient assembly of the present utility model, the other end of the limiting rod is fixedly connected with a limiting disk, and the diameter of the limiting disk is smaller than the diameter of the limiting hole.

[0010] To limit and fix the reinforcing plate between the first bottom shell and the second bottom shell, as an optimized LED bottom shell for convenient assembly of the present utility model, the reinforcing plate is connected to the first bottom shell and the second bottom shell by bolts.

[0011] To assemble and fix the first bottom shell and the second bottom shell, as an optimized LED bottom shell for convenient assembly of the present utility model, the connecting member has a C-shaped structure.

[0020] Please refer to Figures 1 to 4 , a conveniently assembled LED bottom shell, including a first bottom shell 1 and a second bottom shell 101 located on the right side of the first bottom shell 1. Installation cavities 102 are provided on the front end faces of both the first bottom shell 1 and the second bottom shell 101. Two positioning cylinders 2 are fixedly connected to the right side of the first bottom shell 1. Limit holes 201 are penetrated and provided on both the upper and lower sides of the outer wall of the positioning cylinder 2. Two fixed cylinders 3 are fixedly connected to the left side of the second bottom shell 101. A positioning plate 301 matching the positioning cylinder 2 is arranged inside the fixed cylinder 3. A spring 302 is installed between one end of the positioning plate 301 and the inside of the fixed cylinder 3. Limit rods 303 matching the limit holes 201 are installed on both the upper and lower sides of the outer wall of the positioning plate 301. Grooves are provided on both the upper and lower sides of the positioning plate 301. A telescopic spring 306 is installed between the inside of the two grooves and the limit rods 303;

[0021] A connecting member 4 is installed on the rear end face between the first bottom shell 1 and the second bottom shell 101. Two grooves are provided on the rear end face of the connecting member 4. Reinforcing plates 401 are installed inside the two grooves.

[0022] In this embodiment: Bring the first bottom shell 1 and the second bottom shell 101 close to each other and abut. At the same time, pinch the two limit rods 303 to move closer to each other, causing the telescopic spring 306 to compress, so that the two limit discs 304 and the positioning plate 301 enter the positioning cylinder 2 under the elastic force of the spring 302 until the limit rods 303 are aligned with the limit holes 201. At the same time, the telescopic spring 306 loses the extrusion force and can push the limit rods 303 through the limit holes 201, thereby limiting and fixing the positioning cylinder 2 and the fixed cylinder 3, realizing the convenient assembly of the first bottom shell 1 and the second bottom shell 101;

[0023] Secondly, slide the connecting member 4 from the left side of the first bottom shell 1 and install it on the rear end face of the first bottom shell 1, and move the connecting member 4 towards the connection part of the first bottom shell 1 and the second bottom shell 101 until the connecting member 4 slides to the connection part of the first bottom shell 1 and the second bottom shell 101. Then, fix the reinforcing plate 401 to the first bottom shell 1 and the second bottom shell 101 through bolts, and the connection area between the connecting member 4 and the first bottom shell 1 and the second bottom shell 101 can be increased through the reinforcing plate 401, thereby achieving the effect of stable assembly of the first bottom shell 1 and the second bottom shell 101.

[0024] As a technical optimization solution of the present utility model, threaded holes 202 are provided on both the upper and lower sides of the positioning cylinder 2, and limiting members 305 located outside the limiting rod 303 are provided on both the upper and lower sides of the positioning cylinder 2.

[0025] In this embodiment: The limiting member 305 is stuck on the outer wall of the limiting rod 303 from its notch, and the limiting member 305 is rotated so that the lower end surface of the limiting member 305 is threadedly connected to the threaded hole 202, thereby realizing the limitation of the limiting disc 304, so that the limiting rod 303 is stably connected to the limiting hole 201, achieving the effect of stable assembly of the first bottom shell 1 and the second bottom shell 101.

[0026] As a technical optimization solution of the present utility model, the other end of the limiting rod 303 is fixedly connected with a limiting disc 304, and the diameter of the limiting disc 304 is smaller than the diameter of the limiting hole 201.

[0027] In this embodiment: The limiting rod 303 can be limited by the cooperation of the limiting disc 304 and the limiting member 305, so that the limiting rod 303 is stably installed in the limiting hole 201. Since the diameter of the limiting disc 304 is smaller than the diameter of the limiting hole 201, the limiting disc 304 can smoothly pass through the limiting hole 201.

[0028] As a technical optimization solution of the present utility model, the reinforcing plate 401 is bolted to the first bottom shell 1 and the second bottom shell 101.

[0029] In this embodiment: The reinforcing plate 401 can be limited and fixed to the first bottom shell 1 and the second bottom shell 101 through bolts.

[0030] As a technical optimization solution of the present utility model, the connecting member 4 has a C-shaped structure.

[0031] In this embodiment: Since the connecting member 4 has a C-shaped structure, it is convenient to better assemble and fix the first bottom shell 1 and the second bottom shell 101.

[0032] Working principle: First, bring the first bottom shell 1 into close contact with the second bottom shell 101. At the same time, pinch the two limit disks 304 to move closer to each other, causing the telescopic spring 306 to compress. The limit rod 303 partially enters the groove until the distance between the two limit disks 304 and the positioning plate 301 can enter the positioning cylinder 2. Then, under the elastic force of the spring 302, both the two limit disks 304 and the positioning plate 301 enter the positioning cylinder 2. Due to the elastic force of the telescopic spring 306, the limit disk 304 can contact the inner wall of the positioning cylinder 2 until the limit rod 303 is aligned with the limit hole 201. At the same time, the telescopic spring 306 loses the extrusion force and can push the limit rod 303 through the limit hole 201. Then, snap the limiting member 305 onto the outer wall of the limit rod 303, so that the limit rod 303 is located in the middle of the limiting member 305, and rotate the limiting member 305 to thread the lower end surface of the limiting member 305 with the threaded hole 202. Since the diameter of the hole in the middle of the limit disk 304 is smaller than the diameter of the limit disk 304, the limit disk 304 can be limited by the limiting member 305, and thus the positioning cylinder 2 and the fixed cylinder 3 can be limited and fixed, realizing the convenient assembly of the first bottom shell 1 and the second bottom shell 101;

[0033] Secondly, slide the connecting member 4 from the left side of the first bottom shell 1 and install it on the rear end surface of the first bottom shell 1, and move the connecting member 4 towards the connecting part of the first bottom shell 1 and the second bottom shell 101 until the connecting member 4 slides to the connection between the first bottom shell 1 and the second bottom shell 101. Then, fix the reinforcing plate 401 to the first bottom shell 1 and the second bottom shell 101 with bolts, and the connection area between the connecting member 4 and the first bottom shell 1 and the second bottom shell 101 can be increased through the reinforcing plate 401, thereby achieving the effect of stable assembly of the first bottom shell 1 and the second bottom shell 101.

[0034] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
