[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a splicing and expandable video special effects display stand, including a base plate 1, a support column 2, a top plate 3, a mounting platform 4, a main display screen 5, a square sleeve 6, locking bolts 7, locking nuts 8, a track groove 9, a support rod 10, an expansion sleeve 11, a bottom limiting column 12, a limiting groove 13, a stabilizing rod 14, a stabilizing hole 15, an expansion mounting hole 16, a bottom positioning groove 17, and a top positioning groove 18. A support column 2 is fixed to the center of the top surface of the base plate 1, and the top of the support column 2 is connected and fixed to the center of the bottom surface of the top plate 3. A mounting platform 4 is fixed to the center of the top surface of the top plate 3, and the main display screen 5 is mounted on the top of the mounting platform 4. A square sleeve 6 is installed at the bottom of the support column 2, and a lock is installed through a hole opened on the bottom side of the square sleeve 6. A locking nut 8 is installed on one end of a fixing bolt 7, and the other end of the locking bolt 7 is fitted to the inner wall of the track groove 9. The track groove 9 is opened on the side of the support column 2. A support rod 10 is rotatably installed on the top side of the square sleeve 6. The top of the support rod 10 is rotatably connected to the bottom surface of the expansion sleeve 11. The inner wall of the expansion sleeve 11 is fitted to one end of the top plate 3. A bottom limiting post 12 is fixed to one end of the bottom surface of the inner side of the expansion sleeve 11. The bottom limiting post 12 is fitted to the inner wall of the limiting groove 13. The limiting groove 13 is opened on the bottom surface of the top plate 3. A stabilizing rod 14 is fixed to the inner side of the other end of the expansion sleeve 11. The stabilizing rod 14 is fitted to the inner wall of the stabilizing hole 15. The stabilizing hole 15 is opened on the side of the top plate 3. An expansion installation hole 16 is opened at the top end of the expansion sleeve 11.

[0016] In this example, the locking bolts 7 are symmetrically distributed about the center of the square sleeve 6. The locking bolts 7 are slidably connected to the track groove 9. The top view of the track groove 9 is T-shaped. The above structural design allows the square sleeve 6 to slide stably and linearly along the track groove 9 with the locking bolts 7, and the locking bolts 7 will not detach from the track groove 9.

[0017] The length of the support rod 10 is greater than half the length of the support column 2. The support rod 10 is symmetrically distributed about the center of the support column 2. The above structural design makes the length of the support rod 10 sufficient to stably drive and support the extension sleeve 11.

[0018] The expansion sleeve 11 is symmetrically distributed about the center of the top plate 3. The expansion sleeve 11 and the top plate 3 are slidably connected. The above structural design enables the expansion sleeve 11 to be stably stored and horizontally moved and unfolded.

[0019] The bottom limiting post 12 and the stabilizing rod 14 are slidably connected to the limiting groove 13 and the stabilizing hole 15, respectively. The side view cross-sectional shape of the bottom limiting post 12 and the limiting groove 13 is "T" shaped. The length of the limiting groove 13 and the stabilizing hole 15 is not less than 1 / 3 of the front view length of the top plate 3. The above structural design makes the expansion sleeve 11 highly stable when stored and slidably unfolded.

[0020] The expansion sleeve 11 has a bottom positioning groove 17 at the top center of one side and a top positioning groove 18 at the bottom center of one side. The inner wall of the bottom positioning groove 17 fits against the top side of the support column 2, and the inner wall of the top positioning groove 18 fits against the side of the mounting platform 4. The above structural design allows the expansion sleeve 11 to fit stably against the mounting platform 4 and the support column 2 when stored, ensuring a tight overall structure and a certain degree of aesthetics.

[0021] Working principle: When using, push... Figure 2 The square sleeve 6 slides vertically upward along the support column 2. The square sleeve 6, with the locking bolt 7, slides vertically upward along the track groove 9. The square sleeve 6 pushes the bottom end of the support rod 10. The support rod 10 rotates and pushes the extension sleeve 11 to slide horizontally to both sides along the top plate 3. The extension sleeve 11, with the bottom limit post 12, slides steadily in a straight line along the limit groove 13. The stabilizing rod 14 also slides steadily relative to the stabilizing hole 15. Once the expansion sleeve 11 is positioned correctly, rotate the locking nut 8 to press the square sleeve 6 into contact with and fix it to the support column 2. The square sleeve 6 and the expansion sleeve 11 provide stable support and positioning for the expansion sleeve 11. Different professional equipment can be installed through the multiple expansion mounting holes 16, and a comprehensive video effects display can be carried out in conjunction with the main display screen 5. This is the working principle of the splicing expansion video effects display stand.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
