[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] See also Figure 1-5An electronic billboard, in the technical solution proposed by the utility model, comprises a lamp pole 1 and an electronic billboard body 2 mounted on the lamp pole 1, a first arc plate 31 is fixedly mounted on the electronic billboard body 2, a second arc plate 32 is mounted on the first arc plate 31 by bolts 33, and further comprises: a limiting mechanism, the limiting mechanism comprises a limiting block 41 slidably mounted in the second arc plate 32, a connecting plate 42 is fixedly mounted between the two second arc plates 32, a screw rod 43 is rotatably mounted on one side of the connecting plate 42, and a screw rod 43 is threadedly connected to a vertical sliding arrangement on one side of the connecting plate 42 The lifting mechanism includes a support rod 52 arranged on the bottom side of the second curved plate 32 at the bottom, and a rotating rod 53 is rotatably installed on one side of the support rod 52, and the rotating rod 53 is clamped with the screw 43; wherein a first inclined surface is arranged at the bottom of one end of the limit block 41 close to the abutment block 45, and a second inclined surface is arranged at the top of one end of the abutment block 45 close to the limit block 41, and the abutment block 45 abuts against the first inclined surface on the limit block 41 through the second inclined surface thereon, so that the limit block 41 slides, and the electronic billboard body 2 is lifted up by the first curved plate 31 and the second curved plate 32 through the screw The bolt 33 is installed on the lamp pole 1, and the first curved plate 31 and the second curved plate 32 are combined to form a ring so as to be sleeved on the lamp pole 1. Then the electronic billboard body 2 is moved upward until the distance between the bottom end of the electronic billboard body 2 and the ground is enough to put down the support rod 52. At this time, the support rod 52 is placed under the bottom second curved plate 32 to support it, and then the support rod 52 is used to push the bottom second curved plate 32 upward. At this time, the bottom second curved plate 32 will drive the top second curved plate 32 to move through the connecting plate 42, and the electronic billboard body 2 will move upward. The support rod 52 is placed on the bottom side of the second curved plate 32 below, and the rotating rod 53 is inserted into the screw rod 43 until the electronic billboard body 2 is pushed to the specified height by the support rod 52. The rotating rod 53 is then rotated. At this time, the rotating rod 53 will drive the screw rod 43 to rotate, and the screw rod 43 will drive the abutment block 45 threadedly connected thereto to slide upward. As the abutment block 45 moves upward, the abutment block 45 will abut the limit block 41 so that the limit block 41 moves toward the direction of the lamp pole 1 and is squeezed on the lamp pole 1, thereby limiting the downward movement of the first curved plate 31 and the second curved plate 32.

[0024] Specifically, a connecting block 421 is fixedly mounted on the connecting plate 42 , and the screw rod 43 is rotatably mounted in the connecting block 421 ; the connecting block 421 facilitates the screw rod 43 to be mounted on one side of the connecting plate 42 .

[0025] Specifically, there are two abutment blocks 45 , between which a slide bar 44 is fixedly installed, and the slide bar 44 is vertically slidably installed in the connection block 421 ; the abutment block 45 is vertically slidably installed on one side of the connection plate 42 through the slide bar 44 .

[0026] Specifically, a connector 46 with a T-shaped cross section is horizontally slidably mounted on the connecting block 421, a plurality of slots 431 adapted to the connector 46 are provided on the screw rod 43, a spring is fixedly connected between the short arm end of the connector 46 and the connecting block 421, and a bevel 461 is provided on the connector 46; a plurality of slots 431 are arranged in a circumferential array on the screw rod 43, and when the rotating rod 53 drives the screw rod 43 as shown in FIG. Figure 4 When the screw 43 is rotated clockwise as shown, it will abut against the bevel 461 of the connector 46. At this time, the bevel 461 will be pressed and move out of the connecting block 421 until the connector 46 is aligned with the next slot 431. At this time, the spring will pull the connector 46 into the slot 431. At the same time, the end of the connector 46 inserted into the slot 431 will prevent the screw 43 from being Figure 4 Rotate counterclockwise, and when disassembly is required, a long strip can be provided so that the long strip will overlap the short arm end of the connector 46, and then the connector 46 will be pulled out of the slot 431 to facilitate the rotation of the screw rod 43.

[0027] Specifically, a rubber pad is fixedly installed on one end of the limit block 41 close to the lamp pole 1; when the screw 43 rotates to drive the abutment block 45 to slide and squeeze the limit block 41, the limit block 41 will move toward the lamp pole 1. At this time, the limit block 41 will increase the friction between the lamp pole 1 through the rubber pad, thereby making it difficult for the first curved plate 31 and the second curved plate 32 to slide easily when they are mounted on the lamp pole 1.

[0028] Specifically, the top of the support rod 52 is fixedly connected to a support plate 51, a protrusion 511 is fixedly connected to the support plate 51, and the rotating rod 53 is rotatably installed in the protrusion 511; wherein the support plate 51 is arc-shaped, and the support plate 51 is abutted against the second arc-shaped plate 32 below through the support frame, and at this time the inner wall of the support plate 51 abuts against the lamp pole 1.

[0029] Specifically, a long plate 54 is fixedly connected to the rotating rod 53, and a long groove 432 adapted to the long plate 54 is opened at the bottom end of the screw rod 43; when the support plate 51 is set under the second arc-shaped plate 32 below, the long plate 54 on the rotating rod 53 will be inserted into the long groove 432 at the same time, and then the rotating rod 53 is rotated. At this time, the rotating rod 53 will drive the screw rod 43 to rotate through the cooperation of the long plate 54 and the long groove 432.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
