[0025] As a technical optimization solution of the utility model, by setting the installation component 10, when the user installs the display screen 4, first move the two sides of the bottom of the display screen 4 to the top of the support frame 3, align the bottom of the installation block 103 with the installation groove 102, and then move the display screen 4 downward to make the installation block 103 completely move into the inside of the installation groove 102. The installation groove 102 can be used to limit the moving direction of the installation block 103, so that the connection between the display screen 4 and the support frame 3 is more stable, and then the installation bar 101 is used to facilitate the user to connect the display screen 4 to the support frame 3, thereby achieving the effect of facilitating the user to install the display screen 4.

[0026] refer to Figure 2 The reinforcement assembly 11 includes a reinforcement block 111, four reinforcement blocks 111 are arranged and are equidistantly distributed in a rectangular shape, a reinforcement groove 112 is provided at the top of the support frame 3 and the top of the reinforcement block 111, and a reinforcement rod 113 is threadedly connected to the inner wall of the reinforcement groove 112.

[0027] As a technical optimization scheme of the utility model, by setting a reinforcement component 11, when the user connects the display screen 4 to the support frame 3, the bottom of the reinforcement block 111 is aligned with the top of the support frame 3, so that the reinforcement groove 112 at the bottom of the reinforcement block 111 is aligned with the reinforcement groove 112 at the top of the support frame 3, and then the reinforcement rod 113 is taken out, so that the bottom of the reinforcement rod 113 is aligned with the reinforcement groove 112, and then the reinforcement rod 113 is rotated to move the reinforcement rod 113 to the inside of the reinforcement groove 112, and the reinforcement block 111 and the support frame 3 can be connected together by the reinforcement rod 113, and then the top of the mounting block 103 can be blocked by the reinforcement block 111, so that the mounting block 103 cannot move out of the mounting groove 102, thereby achieving the effect of reinforcing the installation of the display screen 4.

[0028] refer to Figure 4 A slide groove 12 is provided at the top and the bottom of the inner wall of the card slot 5 , and the inner wall of the slide groove 12 is slidably connected to a limit plate 13 .

[0029] As a technical optimization scheme of the utility model, by setting the slide groove 12 and the limit plate 13, when the user installs the protective plate 7, the limit plate 13 is first moved toward the outside of the support frame 3 until the limit plate 13 is out of the slide groove 12. At this time, the limit plate 13 no longer blocks the card slot 5, which is convenient for the user to move the card block 6 to the inside of the card slot 5, and then align the inner side of the limit plate 13 with the slide groove 12, and move the limit plate 13 toward the display screen 4, so that the limit plate 13 is completely moved to the inside of the card slot 5. The limit plate 13 can be used to block the card block 6, so that the card block 6 cannot move out of the card slot 5, thereby achieving the effect of limiting the movement of the card block 6.

[0030] refer to Figure 3 A protection pad 14 is fixedly connected to the back of the protection plate 7, and the material of the protection pad 14 is rubber.

[0031] As a technical optimization solution of the utility model, by setting a protective pad 14, when the user installs the protective plate 7 between the support frames 3, the protective plate 7 will inevitably touch the outside of the display screen 4. The protective pad 14 can reduce the wear caused by the direct contact between the protective plate 7 and the display screen 4. The relatively soft and wear-resistant properties of rubber can be utilized to make the protective pad 14 better protect the display screen 4 and increase the service life of the protective pad 14.

[0032] refer to Figure 4A magnetic block 15 is fixedly connected to the inner side of the limiting plate 13 , and the inner side of the magnetic block 15 is magnetically adsorbed to both sides of the protective plate 7 .

[0033] As a technical optimization solution of the utility model, by setting a magnetic block 15, when the limit plate 13 contacts both sides of the protective plate 7, the limit plate 13 can be adsorbed on both sides of the protective plate 7 by using the magnetic block 15, so that the limiting effect of the limit plate 13 is more stable, avoiding the situation where the limit plate 13 automatically moves out of the card block 6 and causes the card block 6 to move out of the card slot 5, thereby achieving the effect of stabilizing the limit plate 13.

[0034] refer to Figure 4 The outer side of the limiting plate 13 is fixedly connected with an auxiliary bar 16, and a plurality of auxiliary bars 16 are provided and distributed at equal distances.

[0035] As a technical optimization solution of the utility model, by setting an auxiliary strip 16, when the user moves the limit plate 13, the auxiliary strip 16 can be used to increase the friction between the user and the limit plate 13, making it easier for the user to move the limit plate 13, thereby avoiding the effect that the adsorption force of the magnetic block 15 is too large and is not conducive to the user moving out of the limit plate 13, thereby achieving the effect of assisting the movement of the limit plate 13.

[0036] The working principle and use process of the utility model are as follows: first install the display screen 4, move the two sides of the bottom of the display screen 4 to the top of the support frame 3, align the bottom of the mounting block 103 with the mounting groove 102, then move the display screen 4 downward, and move the mounting block 103 completely into the inside of the mounting groove 102. The mounting groove 102 can be used to limit the moving direction of the mounting block 103, so that the connection between the display screen 4 and the support frame 3 is more stable, and then the user can connect the display screen 4 to the support frame 3 through the mounting strip 101. After the user connects the display screen 4 to the support frame 3, the bottom of the reinforcement block 111 is aligned with the top of the support frame 3, so that the reinforcement groove 112 at the bottom of the reinforcement block 111 is aligned with the reinforcement groove 112 at the top of the support frame 3, and then the reinforcement rod 113 is taken out, and the bottom of the reinforcement rod 113 is aligned with the reinforcement groove 112. At this time, the reinforcement rod 113 is rotated to move the reinforcement rod 113 to the inside of the reinforcement groove 112, and the reinforcement block 111 and the support rod can be connected together by the reinforcement rod 113, and then the reinforcement block 113 is used to fix the reinforcement rod 113. The top of the mounting block 103 can be covered by 111, so that the mounting block 103 cannot be moved out of the mounting groove 102. When the user installs the protective plate 7, the limiting plate 13 is first moved toward the outer side of the support frame 3 until the limiting plate 13 is out of the slide groove 12. At this time, the limiting plate 13 no longer blocks the card slot 5, which is convenient for the user to move the card block 6 into the inside of the card slot 5, and then align the inner side of the limiting plate 13 with the slide groove 12, and move the limiting plate 13 toward the display screen 4, so that the limiting plate 13 is completely moved into the inside of the card slot 5. The limiting plate 13 can be used to cover the card block 6, so that the card block 6 cannot move out of the card slot 5. When the user installs the protective plate 7 between the support frames 3, the protective plate 7 will inevitably touch the outer side of the display screen 4. The protective pad 14 can reduce the wear caused by the direct contact between the protective plate 7 and the display screen 4. Then, the relatively soft and wear-resistant characteristics of rubber are used, and the auxiliary block 8 can be used to increase the contact area between the user and the protective plate 7, thereby facilitating the user to carry the display screen 4, thereby achieving the effect of auxiliary carrying.

[0037] To sum up: the spliced ​​LED display screen, by setting the protective plate 7 and the auxiliary block 8, when the user carries the display screen 4, the protective plate 7 can be used to prevent the display screen 4 from being hit by foreign objects, and the auxiliary block 8 can be used to increase the contact area between the user and the protective plate 7, so that the user can move the display screen 4 conveniently. This solves the problem that although the display screen can be easily spliced ​​onto the placement frame and has a certain degree of protection for the display screen, during the transportation process, due to the large exposed area of ​​the display screen, the surface of the display screen is easily hit by foreign objects, thereby causing damage to the display screen.
