DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0030] Example 1, see Figures 1 to 11 As shown, an embedded outdoor electronic billboard includes a cover body 1. Under normal circumstances, the cover body 1 needs to be embedded in the outer wall of the building. A master control module is fixedly installed in the cover body 1. The master control module is used to distribute power and transmit information. The cover body 1 is connected to a sliding door 2, and the cover body 1 is fixedly connected to a shielding plate 3. A pressure frame 4 is fixedly installed on the upper part of the cover body 1, and the pressure frame 4 is fixedly connected to the shielding plate 3. It also includes:

[0031] A displacement adjustment structure 5 connected to the cover body 1, the displacement adjustment structure 5 includes two groups of first electric telescopic rods 6 fixedly connected to the cover body 1, the moving ends of the first electric telescopic rods 6 are fixedly connected to a track frame 7, the track frame 7 is connected to an equidistant separation mechanism 8, and the equidistant separation mechanism 8 is connected to a synchronous steering mechanism 9;

[0032] Four groups of double-sided display structures 10 are connected to the synchronous steering mechanism 9, and the double-sided display structure 10 includes a center frame 11 connected to the synchronous steering mechanism 9, the center frame 11 is fixedly connected to two groups of symmetrically arranged limit frames 12, the limit frames 12 are movably connected to a connecting frame 13, the connecting frame 13 is movably connected to a pressing frame 4, the connecting frame 13 is fixedly connected to a display screen 14, a limiting groove 15 is provided on the side of the connecting frame 13 away from the display screen 14, a swing block 16 hinged to the connecting frame 13 is arranged in the limiting groove 15, and the swing block 16 is fixedly connected to a handle 17.

[0033] In normal operation, only the row of display screens 14 facing outdoors is powered on and receives signals. The display screens 14 facing the same are arranged in a straight line. Two groups of display screens 14 located in the same row and adjacent to each other abut against each other, so that four groups of display screens 14 facing the same are abutted to form a group of large electronic billboards and the large electronic billboards facing outdoors are in a playing state. The pressing frame 4 abuts against the connecting frame 13, and the cover body 1 contacts the display screens 14 facing outdoors to limit the movement of the connecting frame 13. When at least one group of the row of display screens 14 facing outdoors fails, the first electric telescopic rod 6 drives the track frame 7 to move into the cover body 1, and the track frame 7 drives the synchronous steering mechanism 9 to move through the equidistant separation mechanism 8. The equidistant separation mechanism 8 drives the synchronous steering mechanism 9 to move. The synchronous steering mechanism 9 drives the center frame 11 to move away from each other by performing an equidistant separation movement toward the mechanism 9, and the synchronous steering mechanism 9 drives the center frame 11 to reverse, so that the positions of the two rows of display screens 14 are interchanged. When the damaged display screen 14 needs to be repaired or replaced, the personnel rotate the handle 17 to make the swing block 16 abut against the limit groove 15, and then lift the handle 17 upward to make the swing block 16 push the limit groove 15, so that the connecting frame 13 moves upward and disengages from the limit frame 12, so that the display screen 14 is removed. When no one is performing maintenance work, the first electric telescopic rod 6 is reset, and the equidistant separation mechanism 8 drives the synchronous steering mechanism 9 to move, so that the undamaged display screens 14 in the same row abut against each other and face the outdoors. The present invention changes the orientation of the double-sided display structure 10 through the cooperation between the displacement adjustment structure 5 and the double-sided display structure 10 to quickly restore the function of broadcasting advertisements of the present invention, and by moving the damaged display screen 14 into the cover body 1 and toward personnel, it is convenient for personnel to quickly and easily replace the display screen 14, thereby improving the convenience of maintenance and facilitating the long-term and stable advertising delivery operation of the present invention.
