[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Example 1

[0022] The present application embodiment discloses an embedded LED screen structure, referring to Figure 1 , Figure 2 and Figure 3 , including a screen mounting frame and a plurality of LED screens 3. The screen mounting frame includes a fixed screen frame 1 and a movable screen frame 2. The fixed screen frame 1 is fixedly connected to the working wall surface by a first connecting member. The first connecting member can be a connecting bolt. The working wall surface is provided with a screw hole adapted to the connecting bolt. After the fixed screen frame 1 is attached to the working wall surface, the connecting bolt passes through the fixed screen frame 1 and is threadedly connected with the screw hole on the working wall surface. The upper edge of the movable screen frame 2 is hingedly connected to the upper edge of the fixed screen frame 1 by an HL050 square hinge. The side of the movable screen frame 2 away from the fixed screen frame 1 is provided with an installation cavity 21 for accommodating the LED screen 3. The inner bottom wall of the installation cavity 21 is hollowed out. The LED screen 3 is detachably fixedly installed on the inner bottom wall of the installation cavity 21 by means of screw connection.

[0023] A support member for supporting the movable screen frame 2 in the flipped state is provided between the movable screen frame 2 and the fixed screen frame 1. After the movable screen frame 2 is flipped up relative to the fixed screen frame 1, the staff can disassemble the LED screen 3 from the bottom of the movable screen frame 2. Specifically, the angle of the flip screen frame should be no less than 45°. The support member is a hydraulic support rod 4, and a 650-type hydraulic support rod 4 can be selected. One end of the hydraulic support rod 4 is hinged to the fixed screen frame 1, and the other end is hinged to the movable screen frame 2. At least two groups of hydraulic support rods 4 are arranged parallel to each other along the hinge axis of the movable screen frame 2. After the movable screen frame 2 is flipped open, the hydraulic support rod 4 is used to support between the fixed screen frame 1 and the movable screen frame 2, so that the support structure of the flipped movable screen frame 2 is stable. In the embodiment of the present application, a plurality of connecting rods are vertically integrated onto the fixed screen frame 1, and one end of the hydraulic support rod 4 close to the fixed screen frame 1 is hinged on the side wall of the connecting rod. When the movable screen frame 2 is retracted to fit with the fixed screen frame 1, the hydraulic support rod 4 can be stored in parallel on one side of the connecting rod, thereby improving the structural compactness of the screen mounting frame.

[0024] By providing a flip-type movable screen frame 2, the maintenance and installation gap between the LED screen 3 and the working wall can be reduced. When the LED screen 3 needs to be repaired or installed, the movable screen frame 2 is flipped up, and the staff can conveniently install the LED screen 3. In addition, by embedding the LED screen 3 in the installation cavity 21 of the movable screen frame 2, when the movable screen frame 2 is fitted on the fixed screen frame 1, the LED screen 3 can be prevented from protruding from the working wall, reducing direct contact with the LED screen 3 during personnel activities, and extending the service life of the LED screen 3.

[0025] Furthermore, in order to make the structure of the movable screen frame 2 stable when it is fitted with the fixed screen frame 1, in the embodiment of the present application, a limit assembly is also included, and the limit assembly is used to limit the movable screen frame 2 from flipping open relative to the fixed screen frame 1. In the embodiment of the present application, the limit assembly includes a lock buckle, and the fixed part and the movable part of the lock buckle are respectively fixedly installed on the lower edges of the fixed screen frame 1 and the movable screen frame 2 by screws. The fixed part of the lock buckle can be a buckle body with a U-shaped closed loop, and the movable part can be a flip-up loose-leaf piece that can be sleeved on the outside of the buckle body. After the movable part of the lock buckle is connected to the fixed part, a common lock is used to lock it to prevent unauthorized personnel from opening the movable screen frame 2.

[0026] Example 2

[0027] Reference Figure 4 , Figure 5 and Figure 6 The difference between Example 2 and Example 1 is that the structure of the limiting component is different.

[0028] In the embodiment of the present application, the limit component can also be a panel 6, and a mounting groove 5 for accommodating the screen mounting frame is opened on the working wall surface. The panel 6 is detachably connected to the working wall surface at the opening of the mounting groove 5 by screws, and an opening matching the opening size of the mounting cavity 21 is opened through the panel 6. After the movable screen frame 2 is rotated to fit the fixed screen frame 1, the panel 6 is used to be installed and fixed on the working wall surface by moving the working wall surface, and the LED display screen on the movable screen frame 2 is exposed through the opening on the panel 6, which can effectively press the movable screen frame 2 to prevent it from flipping up, and can also make the panel 6 and the LED display screen basically fit the working wall surface, avoiding the LED display screen from being hit.

[0029] In the embodiment of the present application, a heat dissipation cavity 22 is also provided on one side of the movable screen frame 2 away from the installation cavity 21. The heat dissipation cavity 22 is hollowed out and connected to the installation cavity 21, and a criss-cross frame for installing the LED screen 3 is left between the heat dissipation cavity 22 and the installation cavity 21. The four side walls of the movable screen frame 2 are all penetrated with first ventilation holes 23 connected to the heat dissipation cavity 22, and a plurality of second ventilation holes 61 are provided on the panel 6 around the heat dissipation cavity 22. A heat dissipation gap is left around the inner wall of the installation slot 5 on the working wall and the screen installation frame. The panel 6 covers the heat dissipation gap, and the second ventilation holes 61 face the heat dissipation gap, so that the second ventilation holes 61 are connected to the first ventilation holes 23 on the four sides of the movable screen frame 2. A heat dissipation fan 24 is provided on the outside of the first ventilation holes 23 on the outer walls and the lower edge of the movable screen frame 2. The heat dissipation fan 24 is fixedly connected to the movable screen frame 2 by screws, and the air outlet of the heat dissipation fan 24 faces the heat dissipation cavity 22 inside the movable screen frame 2.

[0030] The cooling fan 24 can inhale air from the second ventilation hole 61 on the panel 6, and blow air into the heat dissipation cavity 22 from both sides and the lower edge of the movable screen frame 2. In addition to the wind force blown in by the cooling fan 24, the hot air will naturally rise and be discharged from the first ventilation hole 23 on the movable screen frame 2 at the top of the heat dissipation cavity 22. The compactly installed LED screen 3 is cooled. At the same time, since the LED screen 3 is overall higher after installation, the hot air is discharged from the second ventilation hole 61 on the panel 6 above the LED screen 3, which also prevents the hot air from blowing to pedestrians outside, thereby optimizing the user experience.
