[0037] Among them, the display screen 3 and the rotating piece 6 rotate synchronously, and the rotating piece 6 does not drive the rotation of the mounting frame 5 due to the arrangement of the bearing 63. Moreover, the mounting frame 5 includes a main body 56, and the main body 56 is provided with a mounting piece 51, and the bearing 63 is arranged between the mounting piece 51 and the rotating shaft two 62. At the same time, the connecting plate 52 is arranged on the top of the main body 56, and the connecting plate 52 is used to shield the structure below the connecting plate 52 to play a protective role, and make the appearance good-looking.

[0038] Moreover, the rotation of the display screen 3 needs to be limited, so the main body 56 is provided with a limiting plate one 53 and a limiting plate two 54, and the limiting plate one 53 and the limiting plate two 54 are both provided with a gasket 55.

[0039] Therefore, in actual use, the gasket 55 of the limiting plate one 53 is used to contact the display screen 3 after rotation, and the gasket 55 of the limiting plate two 54 is used to contact the display screen 3 before rotation. Moreover, the limiting plate one 53 and the limiting plate two 54 can be arranged on the main body 56 by screws, or be integrally formed with the main body 56.

[0040] Secondly, the mounting structure of the mounting frame 5 is that: Figure 6 As shown, first, the base 1 is provided with a mounting plate 12 on both sides of the placing groove 11, one side of the mounting plate 12 is located in the placing groove 11, and the slot rail 121 is opened on the mounting plate 12, and the fastener passes through the mounting frame 5 and enters the slot rail 121 to set the mounting frame 5 in the placing groove 11.

[0041] Among them, the fastener is a screw, and the slot rail 121 is arranged, so that the position of the mounting frame 5 can be adjusted according to the different positions of the fastener. Therefore, it can be applied to different sizes of display screens 3.

[0042] As shown in the figure and Figure 3 , the structure related to the driving source 4 is that: first, the base 1 and the display screen 3 are provided with a telescopic rod 7, and the telescopic rod 7 is located on one side of the driving source 4.

[0043] Meanwhile, the telescopic rod 7 comprises an outer rod 71 and a movable inner rod 72, the bottom of the outer rod 71 is connected with the inner bottom surface of the placing groove 11, and the two ends of the inner rod 72 are connected with the outer rod 71 and the display screen 3 respectively, and the inner rod 72 can move on the outer rod 71 along with the rotation of the display screen 3 and support the display screen 3.

[0044] Therefore, in actual use, the telescopic rod 7 can support the display screen 3, and the mounting structure of the telescopic rod 7 and the driving source 4 is that the inner bottom surface of the placing groove 11 is provided with a bracket 14, the display screen 3 is provided with a bracket 13, and the two ends of the telescopic rod 7 and the two ends of the driving source 4 are rotatably connected with the bracket 13 and the bracket 14 respectively.

[0045] The rotation connection generally adopts a shaft hole matching structure. The driving source 4 is an existing structure, i.e. an electric push rod, and its principle is that the electric motor provides power, drives the screw nut after one-stage gear deceleration, converts the rotary motion of the electric motor into the linear motion of the push rod along the guide rail, and realizes the reciprocating motion of the push rod through the forward and reverse rotation of the electric motor.

[0046] As shown in Figure 5 , the display screen 3 comprises a front plate 32, a rear plate 33 and a circuit board 34 between the front plate 32 and the rear plate 33, and the front plate 32 and the rear plate 33 are connected through connecting rods 35, and adjacent two connecting rods 35 are connected through connecting blocks 36.

[0047] Therefore, in actual use, the shell of the display screen 3 is not only two front and rear shells, but is divided into multiple shells, so that it is more convenient to process, is a relatively simple component, and can be replaced in the corresponding part during maintenance and replacement, without the need for full replacement.

[0048] The structure between the connecting block 36 and the connecting rod 35 is that the connecting block 36 is provided with a protruding block 361, the connecting rod 35 is provided with a mounting groove 352 corresponding to the protruding block 361, and the protruding block 361 and the mounting groove 352 are fastened through screws after being matched.

[0049] The structure between the front plate 32, the rear plate 33 and the connecting rod 35 is that the connecting rod 35 is provided with a connecting groove 351, and the front plate 32 is located in the connecting groove 351 of the four connecting rods 35 respectively.

[0050] As shown in Figure 7 , the structure of the lamp body 2 is that the inner wall of the lamp body 2 is shaped into the inner side wall of the placing groove 11, and the lamp body 2 comprises a lamp body 21 and a lamp body 22.

[0051] The lamp body 1 21 has a built-in lamp bead 23 and is located on the front and rear sides of the base 1; while the lamp body 22 is located on the front and rear sides of the base 1 and includes the outer shell 24 and three built-in lamp beads 23. Two of the three lamp beads 23 are symmetrically arranged and the included angle between the two lamp beads 23 is 90 degrees to 120 degrees. At the same time, another lamp bead 23 is located between the two lamp beads 23, and the outer shell 24 is provided with a transparent plate 25 corresponding to the other lamp bead 23.

[0052] Therefore, in actual use, different lamp bodies 2 are used for different positions, thus adapting to different usage scenarios. Moreover, the transparent plate 25 serves as an illumination device because although the outer shells of lamp body one 21 and lamp body two 22 are translucent, they are colored, resulting in poor illumination. At the same time, both outer shell one 26 and outer shell two 24 cover the upper and lower shells, and the LED 23 is located between the upper and lower shells.

[0053] like Figure 2 As shown, two protective covers 8 are symmetrically arranged at the bottom of the base 1, and each protective cover 8 has a sound outlet 81 and a built-in speaker 9, and the two speakers 9 are located on both sides of the placement slot 11.

[0054] Therefore, in actual use, the horn 9 serves as a warning device, meaning the warning light provides not only visual but also audible warnings. Furthermore, both are located on the same component, without requiring additional audio output devices.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
