A live broadcast display device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A live broadcast screen display device includes a display screen, a bottom plate, an extension rod, and running wheels. Mounting grooves are provided at both ends of the bottom plate, extension rods are symmetrically rotatably connected in the mounting grooves, running wheels are rotatably connected to the heads of the extension rods, a vertical rod is movably inserted into the top of the bottom plate along the vertical direction, a docking ring is movably inserted into the head of the vertical rod, a side surface of the docking ring is fixedly connected to the rear side surface of the display screen, and an adjustment component for unfolding or storing four sets of running wheels is provided on the top of the bottom plate.

[0007] An adjusting bolt is screwed into the side surface of the docking ring, and the vertical rod is provided with adjusting holes equidistantly along the vertical direction. The tail of the adjusting bolt is screwed into any adjusting hole on the side surface of the vertical rod.

[0008] An auxiliary shoulder is fixedly provided at the bottom of the outer wall of the vertical rod, and the bottom of the auxiliary shoulder abuts against the top of the bottom plate. A mounting bolt is threaded into the front side of the bottom plate, and the mounting bolt is threaded into the adjustment hole at the bottom of the vertical rod.

[0009] The adjustment assembly comprises an incomplete toothed disc, a locking bolt, and a protection box, and an incomplete toothed disc is fixedly arranged on the top of the extension rod rotating shaft.

[0010] Optionally, the incomplete toothed discs at the ends of the extension rods arranged in pairs are meshed with each other, and a protection box is fixedly provided on the top of the incomplete toothed discs on the top of the bottom plate.

[0011] Optionally, the protection box has a locking bolt threaded into the top of the incomplete toothed disc, and the bottom of the locking bolt contacts the top of the incomplete toothed disc.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model is provided with a bottom plate and four groups of extension rods at the bottom of the display screen to form a stable support structure for the display screen, and an adjustment component is provided on the top of the bottom plate at the rotation position of the extension rods. The adjustment component can drive the four groups of extension rods to unfold to stably support the display screen when the entire display screen needs to be used. The adjustment component can store and fold the four groups of extension rods when the entire display device needs to be stored to avoid occupying a large storage space.

[0014] 2. The display screen of the utility model is indirectly connected to the bottom plate through the vertical rod and the docking ring. Since the vertical rod is provided with adjustment holes equidistantly along the vertical direction, the setting of the adjustment bolt allows the user to adjust the height of the display screen according to the use requirements within a certain degree.

[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 1-3 A live broadcast screen display device includes a display screen 4, a bottom plate 12, an extension rod 8, and a running wheel 9. Both ends of the bottom plate 12 are provided with mounting grooves 14. The mounting grooves 14 are symmetrically rotatably connected with the extension rod 8. The head of the extension rod 8 is rotatably connected with the running wheel 9, and the running wheel 9 is selected as a universal wheel.

[0021] A vertical rod 2 is movably inserted into the top of the bottom plate 12 along the vertical direction, a protective slope 1 is provided on the top of the vertical rod 2, a docking ring 5 is movably inserted into the head of the vertical rod 2, the side of the docking ring 5 is fixedly connected to the rear side of the display screen 4, and an adjustment component for unfolding or storing the four sets of running wheels 9 is provided on the top of the bottom plate 12. An adjusting bolt 6 is threaded into the side of the docking ring 5, and the vertical rod 2 is provided with adjustment holes 3 equidistantly along the vertical direction. The tail end of the adjusting bolt 6 is threaded into any adjustment hole 3 on the side of the vertical rod 2. By controlling the adjusting bolt 6 to be screwed into any adjustment hole 3, the display height of the display screen 4 can be controlled to a certain extent.

[0022] An auxiliary shoulder 11 is fixedly provided at the bottom of the outer wall of the vertical rod 2, and the bottom of the auxiliary shoulder 11 is against the top of the bottom plate 12. A mounting bolt 15 is threaded into the front side of the bottom plate 12, and the mounting bolt 15 is threaded into the adjustment hole 3 at the bottom of the vertical rod 2. The adjustment assembly includes an incomplete toothed disc 13, a locking bolt 7, and a protective box 10. An incomplete toothed disc 13 is fixedly provided on the top of the rotating shaft of the extension rod 8.

[0023] The incomplete toothed discs 13 at the ends of the extension rods 8 arranged in pairs are meshed with each other, and a protection box 10 is fixedly arranged on the top of the bottom plate 12 at the top of the incomplete toothed disc 13. The protection box 10 has a locking bolt 7 threaded into the top of the incomplete toothed disc 13, and the bottom of the locking bolt 7 contacts the top of the incomplete toothed disc 13. The locking bolt 7 is used to limit the rotation of the incomplete toothed disc 13.

[0024] The specific implementation steps and principles of the utility model are as follows:

[0025] When the entire display device is in the storage state, the four groups of extension rods 8 are at the shortest distance from each other. At this time, the locking bolts 7 are in a tightened state. When the four groups of extension rods 8 need to be unfolded, the two locking bolts 7 are loosened. At this time, the four incomplete toothed discs 13 can rotate freely. The user bends the two extension rods 8, and after the four extension rods 8 are driven by the incomplete toothed discs 13 to unfold to the appropriate positions, the locking bolts 7 are tightened again.

[0026] The above 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 substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
