DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3A cabinet for an LED billboard for business activities and exhibitions includes a base 1, a storage groove 16 is provided on the upper end surface of the base 1, a billboard body 3 is provided in the storage groove 16 through a lifting frame 2, a bottom groove 4 is provided on the bottom wall of the base 1, a driving motor is provided in the bottom groove 4 through a supporting frame 5, a horizontal screw 8 is provided in the bottom groove 4 through a fixing plate 7, the horizontal screw 8 is connected to the driving motor through a transmission mechanism, a vertical screw 17 connected to the driving motor is provided in the storage groove 16, a threaded connection groove 18 matching the vertical screw 17 is provided on the billboard body 3, a fixed shaft 13 is fixedly provided in the bottom groove 4, a rotating gear 14 is rotatably provided on the fixed shaft 13, a universal wheel 15 is provided on the rotating gear 14, a movable frame 10 is threadedly sleeved on the horizontal screw 8, and the rotating gear 14 is connected to the movable frame 10 through a rotating mechanism.

[0021] The transmission mechanism includes a driving gear 6 arranged on the output shaft of the driving motor, and a transmission gear 9 meshing with the driving gear 6 is installed on the end of the horizontal screw 8. As shown in the figure, the driving gear 6 and the transmission gear 9 are both bevel gears, and the transmission gear 9 meshes with the driving gear 6 vertically.

[0022] The rotating mechanism includes a rack 12 arranged on the movable frame 10 , the rack 12 is meshed with the rotating gear 14 , and the rack 12 is arranged on the bottom wall of the movable frame 10 . The movable frame 10 is U-shaped in top view, and two racks 12 are arranged on one movable frame 10 .

[0023] A limiting rod 11 connected to the fixed plate 7 is provided in the bottom groove 4. The limiting rod 11 slides through the movable frame 10. The limiting rod 11 is arranged parallel to the transverse screw 8, which limits the movable frame 10 and effectively prevents it from rotating with the transverse screw 8.

[0024] Limit blocks are provided on the outer walls on both sides of the lifting frame 2, and limit grooves 19 corresponding to the limit blocks are provided on the inner walls on both sides of the storage groove 16. The limit blocks firstly limit the lifting frame 2 to prevent it from rotating with the vertical screw 17, and secondly have a limiting function to prevent the lifting frame 2 from being separated from the storage groove 16.

[0025] A rubber pad is provided on the surface of the base 1 that contacts the ground, and anti-skid patterns are provided on the surface of the rubber pad that contacts the ground. The rubber pad protects the bottom wall of the base 1 and the ground to prevent wear and tear between the two. Secondly, the anti-skid patterns ensure the anti-skid property of the base 1 when placed on the ground.

[0026] When the utility model is used, Figure 1 As shown, at this time, the billboard body 3 rises and unfolds along with the lifting frame 2, realizing the exposure and display operation of the billboard body 3. In this state, the universal wheels 15 are in a folded and stored state, and the entire device is supported by the base 1.

[0027] When the exhibition is over, the driving motor is started, and the driving motor drives the active gear 6 and the vertical screw 17 to rotate synchronously. When the vertical screw 17 rotates, the lifting frame 2 descends into the storage groove 16 to drive the billboard body 3 to complete the storage. When the active gear 6 rotates, it can drive the transmission gear 9 to rotate. The transmission gear 9 can drive the horizontal screw 8 to rotate. When the horizontal screw 8 rotates, the movable frame 10 on the outer wall moves. The movable frame 10 drives the rotating gear 14 to rotate with the help of the rack 12, and the rotating gear 14 drives the universal wheel 15 to rotate. The universal wheel 15 finally rotates 90 degrees to expand to support the base 1 and other components. At this time, it can be conveniently moved and transported with the help of the universal wheel 15.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
