[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0022] Example: See Figure 1-4 The utility model provides a technical solution: a LED display screen mask structure, including a mounting plate 1 and a lamp bead body 11, a plurality of lamp holes 2 are distributed on the mounting plate 1, the lamp bead body 11 is located in the inner cavity of the lamp hole 2, a plurality of positioning columns 6 are arranged at the bottom of the mounting plate 1, and a plurality of fixing frames 3 are fixedly arranged at the top of the mounting plate 1.

[0023] Among them, a plurality of positioning columns 6 are evenly distributed in a rectangular shape at the bottom of the mounting plate 1 , and a plurality of anti-sliding blocks 7 are arranged on the outer ring of the positioning columns 6 .

[0024] In this embodiment, the mounting plate 1 is covered on the top of the LED display screen, and then the mounting plate 1 is pressed downward so that the positioning column 6 is engaged with the corresponding connection hole on the display screen;

[0025] Reference Figure 2 , a plurality of positioning posts 6 are evenly distributed below the mounting plate 1, which play a limiting role, so that the connection between the mounting plate 1 and the display screen is not prone to shaking;

[0026] The anti-sliding block 7 is made of silicone. When the positioning column 6 is engaged with the connecting hole of the display screen, the anti-sliding block 7 is inserted into the gap between the positioning column 6 and the connecting hole to increase the friction damping when the positioning column 6 is pulled out, so that the connection between the mounting plate 1 and the display screen is more firm and not easy to fall off, thereby improving the practicality of the device.

[0027] Among them, several lamp holes 2 correspond to several fixing frames 3 one by one, and a trapezoidal groove 10 is opened on the top of the fixing frame 3. The trapezoidal groove 10 is an inverted trapezoid, that is, the top diameter of the trapezoidal groove 10 is larger than the bottom diameter, and the top of the fixing frame 3 is horizontal with the top of the lamp bead body 11.

[0028] In this embodiment, when the mounting plate 1 is connected to the display screen, the lamp bead body 11 is located in the inner cavity of the lamp hole 2. Affected by the position limitation of the positioning column 6, the lamp hole 2 and the lamp bead body 11 can be more accurately connected;

[0029] Reference Figure 4 After the device is installed, the top of the lamp bead body 11 is in the inner cavity of the fixing frame 3, so that the lamp bead body 11 is protected by the fixing frame 3 to prevent foreign objects from directly contacting the lamp bead body 11, thereby eventually causing damage to the lamp bead body 11, so as to further improve the practicality of the device;

[0030] The trapezoidal groove 10 is used to expand the opening diameter of the fixing frame 3 to expand the light-emitting range of the lamp bead body 11, reduce or avoid the influence of the fixing frame 3 on the light-emitting effect of the lamp bead body 11, and avoid the situation where the lamp bead body 11 is lacking in color or the red light is diffused when the display screen is viewed from the side. In this way, while ensuring that the lamp bead body 11 can be protected, the light-emitting performance of the lamp bead body 11 will not be affected, so as to further improve the practicality of the device.

[0031] There are multiple screw holes 5 evenly distributed on the bottom of the mounting plate 1 , and the top of the positioning column 6 is connected with a stud 8 , which is connected to the screw hole 5 through a threaded connection.

After the device is processed in the factory, the positioning column 6 can be stored separately, and the positioning column 6 and the mounting plate 1 can be sent out at the same time as an accessory. After the customer receives it, the positioning column 6 can be connected to the screw hole 5 through the stud 8 to reduce the space occupied by the device, so that a large number of mounting plates 1 can be stacked for storage or transportation, so as to improve the convenience of use of the device.

[0033] Wherein, a plurality of rubber strips 9 are arranged at the bottom of the mounting plate 1 .

[0034] In this embodiment, the rubber strip 9 is used to prevent the mounting plate 1 from causing friction damage to the display screen, thereby improving the safety of the device;

[0035] When the mounting plate 1 is connected to the display screen, there is a certain gap between the mounting plate 1 and the display screen due to the influence of the rubber strip 9. The heat generated by the lamp bead body 11 during operation can be discharged through the gap to prevent the mounting plate 1 from directly absorbing the heat and causing reverse heating of the display screen.

[0036] Wherein, a plurality of grooves 4 are provided on both sides of the mounting plate 1 .

[0037] In this embodiment, the groove 4 can facilitate the staff to remove the installation plate 1, so as to improve the convenience of using the device.
