Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figure 1-6 The utility model provides the following technical solutions: a high heat dissipation LED display screen, including a heat dissipation base 1, a display screen body 3 is arranged on the upper end of the heat dissipation base 1, the display screen body 3 and the heat dissipation base 1 are fixedly connected by a display screen fixing mechanism 4, a heat dissipation mechanism 2 is arranged inside the heat dissipation base 1, and a heat dissipation groove 5 is opened at the lower end of the display screen body 3 corresponding to the position of the heat dissipation mechanism 2.

[0027] Specifically, the display screen fixing mechanism 4 includes a fixing component 41, a slot 42, a block 43 and a fixing hole 44. A block 43 is provided at the lower corner of the display screen body 3, and a fixing hole 44 is provided on the side of the block 43. A slot 42 corresponding to the block 43 is provided at the upper end of the heat dissipation base 1, and a fixing component 41 is provided inside the side of the slot 42.

[0028] By adopting the above technical solution, in order to ensure the heat dissipation effect of the display screen body 3, the block 43 at the lower end of the display screen body 3 is inserted into the card slot 42 inside the heat dissipation base 1, and then the fixing component 41 and the fixing hole 44 are used to fix the display screen body 3.

[0029] Specifically, the fixing assembly 41 includes a latch 411 and a spring 413 . The spring 413 is disposed inside the side of the slot 42 , and the latch 411 is disposed at the other end of the spring 413 .

[0030] By adopting the above technical solution, when disassembling the display screen body 3, the display screen body 3 is pried with force, so that the display screen body 3 drives the block 43 to slide out from the inside of the slot 42. At the same time, the block 43 squeezes the pin 411 and the spring 413, and makes the pin 411 slide out from the inside of the fixing hole 44, so that the display screen body 3 can be disassembled.

[0031] Specifically, a limiting plate 412 is provided at the connection between the latch 411 and the spring 413 , and the other end of the latch 411 is provided as an arc structure.

[0032] By adopting the above technical solution, the setting of the limiting plate 412 can prevent the vertical portion of the latch 411 from being inserted into the interior of the fixing hole 44, resulting in the inability to disassemble the display screen body 3 later.

At the same time, the block 43 will squeeze the bayonet 411 and the spring 413, and make the bayonet 411 slide out from the inside of the fixing hole 44, so that the display screen body 3 can be disassembled. The setting of the limit plate 412 can prevent the vertical part of the bayonet 411 from being inserted into the inside of the fixing hole 44, which makes it impossible to disassemble the display screen body 3 later.

[0034] Example 2

[0035] The difference between this embodiment and the first embodiment is that the heat dissipation mechanism 2 includes a mounting channel 21 and a heat dissipation component 22 . The mounting channel 21 is provided inside the heat dissipation base 1 , and the heat dissipation component 22 is provided inside the mounting channel 21 .

The other end of the heat dissipation channel 223 is arranged with a installation box 222, and the interior of the installation box 222 is arranged with a heat dissipation fan 225.

[0038] By adopting the above technical solution, the cooling fan 225 inside the installation box 222 is turned on, and the cooling fan 225 sends the cold air out through the cooling channel 223, and then blows the cold air out through the blowing port 224, so that the cold air can enter the interior of the display screen body 3 through the heat dissipation slot 5, and directly dissipate heat and cool the display screen body 3.

[0039] Specifically, the installation box 222 is fixedly connected to the heat dissipation base 1 by screws.

[0040] By adopting the above technical solution, the arrangement of the structure can facilitate the installation and fixation of the installation box 222.

[0041] Specifically, a dustproof net 221 is fixedly connected to the side of the installation box 222 .

[0042] By adopting the above technical solution, the provision of the dustproof net 221 can prevent dust from being blown into the interior of the display screen body 3 .

[0043] When this embodiment is in use, the cooling fan 225 inside the installation box 222 is turned on, and the cooling fan 225 sends cold air through the cooling channel 223, and then blows the cold air out through the blowing port 224, so that the cold air can enter the interior of the display screen body 3 through the heat dissipation slot 5, and directly dissipate heat and cool the display screen body 3.

[0044] Working principle and use process of the utility model: When the utility model is used, in order to ensure the heat dissipation effect of the display screen body 3, the card block 43 at the lower end of the display screen body 3 is inserted into the card slot 42 inside the heat dissipation base 1, and then the fixing component 41 and the fixing hole 44 are matched to realize the fixing of the display screen body 3. When the display screen body 3 is disassembled, the display screen body 3 is pried with force, so that the display screen body 3 drives the card block 43 to slide out from the inside of the card slot 42, and at the same time, the card block 43 will squeeze the card pin 411 and the spring 413, and make The latch 411 can slide out from the inside of the fixing hole 44, and the display screen body 3 can be removed. The setting of the limit plate 412 can prevent the vertical part of the latch 411 from being inserted into the inside of the fixing hole 44, which makes it impossible to remove the display screen body 3 later; turn on the cooling fan 225 inside the installation box 222, and the cooling fan 225 sends the cold air through the cooling channel 223, and then blows the cold air out through the blowing port 224, so that the cold air can enter the inside of the display screen body 3 through the heat dissipation slot 5, and directly dissipate the heat and cool the display screen body 3.
