Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown, a telescopic video conferencing set includes a longitudinally arranged fixed plate 1 and a telescopic plate 18 movably connected to the fixed plate 1. A telescopic structure 10 connects the telescopic plate 18 and the fixed plate 1. The telescopic structure 10 includes a first guide post 11 mounted on the fixed plate 1, with a pair of spaced-apart first sliding sleeves 12 slidably mounted on the first guide post 11. A second guide post 13 is mounted on the telescopic plate 18, with a pair of spaced-apart second sliding sleeves 14 slidably mounted on the second guide post 13. Two sets of [unclear text - possibly referring to a specific type of device] are provided between the telescopic plate 18 and the fixed plate 1. The upper folding module 15 is rotatably connected to two adjacent folding modules 15. The inner folding module 15 is hinged to the first sliding sleeve 12, and the outer folding module 15 is hinged to the second sliding sleeve 14. The fixed plate 1 is provided with a locking mechanism 2 to lock the first sliding sleeve 12. The telescopic plate 18 is equipped with a lifting plate 40, and the lifting plate 40 is equipped with a conference display 19. The lifting plate 40 can adjust its height by moving vertically in the telescopic plate 18. The telescopic plate 18 is provided with a lifting drive 4, and the driving end of the lifting drive 4 is connected to the lifting plate 40.

[0022] By pulling the telescopic plate 18, in conjunction with multiple folding modules 15, the telescopic plate 18 can move closer to or further away from the fixed plate 1. The lifting plate 40 can move independently on the telescopic plate 18 to meet the needs of users of different heights and meeting scenarios. During the telescopic movement, the two folding modules 15 unfold, the first sliding sleeve 12 slides along the first guide post 11, and the second sliding sleeve 14 slides along the second guide post 13 to adapt to different telescopic length adjustments. The first guide post 11 of the fixed plate 1 and the second guide post 13 of the telescopic plate 18 form a double guide, ensuring that the movement trajectory of the telescopic plate 18 remains stable during forward and backward movement, significantly improving display stability. When not in use, it can be completely folded for storage, reducing the space occupied on the wall or floor and solving the problem of large conference display equipment occupying space for a long time.

[0023] Specifically, the folding module 15 includes a first rotating rod 16 and a second rotating rod 17 that are rotatably connected. The middle ends of the first rotating rod 16 and the second rotating rod 17 are rotatably connected. A shaft-hole connection is used, allowing the first rotating rod 16 and the second rotating rod 17 to be folded or unfolded. When unfolded, they are arranged in an X-shape; when folded, they are in a straight line. The bottom ends of the first rotating rod 16 and the second rotating rod 17 on the inner side of the folding module 15 are hinged to the corresponding first sliding sleeves 12; the bottom ends of the first rotating rod 16 and the second rotating rod 17 on the outer side of the folding module 15 are hinged to the corresponding second sliding sleeves 14. When the first rotating rod 16 and the second rotating rod 17 are folded or unfolded, the corresponding first sliding sleeves 12 and the second sliding sleeves 14 slide along the corresponding first guide post 11 or second guide post 13 to coordinate with the overall unfolding or folding and ensure stability.

[0024] Furthermore, the outer walls of the first guide post 11 and the second guide post 13 are respectively formed with guide strips along the axial direction, and the first sliding sleeve 12 and the second sliding sleeve 14 are respectively formed with guide grooves that slide in cooperation with the guide strips. The sliding cooperation between the guide grooves and the guide strips prevents the first sliding sleeve 12 and the second sliding sleeve 14 from rotating axially, ensuring linear movement, stable connection with the telescopic module, and providing guiding sliding.

[0025] Furthermore, the locking mechanism 2 includes a first locking rod 21 mounted on the fixed plate 1. The first locking rod 21 is located inside the first guide post 11 and is a threaded rod. Multiple first locking sleeves 22 are fitted onto the first locking rod 21, and these sleeves can move along the length of the first locking rod 21. Each first locking sleeve 22 is fitted with a first stop plate 23 that cooperates with the stop of the first sliding sleeve 12. After the telescopic plate 18 extends to the required length via the folding module 15, the first sliding sleeve 12 moves accordingly along the first guide post 11 to the corresponding position. When its posture needs to be fixed, the first locking sleeves 22 are twisted, causing the first stop plates 23 of the two first locking sleeves 22 to abut against the front and rear ends of the first sliding sleeve 12 respectively. At this time, the first sliding sleeve 12 will not move, and the folding module 15 located inside will not continue to fold or unfold, maintaining a stable posture.

[0026] Similarly, the locking mechanism 2 also includes a second locking rod 24 installed on the telescopic plate 18. The second locking rod 24 is located outside the second guide post 13. The second locking rod 24 is a threaded rod, and multiple second locking sleeves 25 are fitted on the second locking rod 24. The multiple second locking sleeves 25 can move along the length direction of the second locking rod 24. The second locking sleeves 25 are fitted with second stop plates 26 that cooperate with the stop of the second sliding sleeve 14. After the telescopic plate 18 is extended and retracted to the required length by the folding module 15, the second sliding sleeve 14 moves accordingly along the second guide post 13 to the corresponding position. When it is necessary to fix its posture, the second locking sleeves 25 are twisted so that the second stop plates 26 of the two second locking sleeves 25 abut against the front and rear ends of the second sliding sleeve 14 respectively. At this time, the second sliding sleeve 14 will not move, and the folding module 15 located on the outside will not continue to fold or unfold, maintaining a stable posture.

[0027] It should be noted that the first guide post 11 is also slidably fitted with a stop sleeve 27, which is connected to the first baffle. When the first locking sleeve 22 moves, the stop sleeve 27 moves synchronously. The second guide post 13 is also slidably fitted with a stop sleeve 27, which is connected to the second baffle. When the second locking sleeve 25 moves, the stop sleeve 27 moves synchronously. The stop sleeves 27 can respectively stop the corresponding first sliding sleeve 12 or second sliding sleeve 14 from folding forward or backward, preventing the folding module 15 from folding or unfolding further and maintaining a stable posture.

[0028] The fixed plate 1 is also provided with a support structure 3 for movably supporting the telescopic plate 18. The support structure 3 includes a first support arm 31 that is laterally swingable and mounted on the fixed plate 1. A second support arm 32 is rotatably mounted on the outer end of the first support arm 31, and the outer end of the second support arm 32 is rotatably connected to the telescopic plate 18. The support structure 3 also includes a support plate 33 mounted on the bottom of the fixed plate 1. The support plate 33 is formed with an arc-shaped groove 34. A hinge shaft 35 connects the first support arm 31 and the second support arm 32. A guide sliding block 36 that moves along the length direction of the arc-shaped groove 34 is installed at the bottom of the hinge shaft 35. In this embodiment, when the telescopic plate 18 achieves telescopic movement through the folding module 15, the first support arm 31 and the second support arm 32 swing synchronously. The guide sliding block 36 connected to the hinge shaft 35 moves along the arc-shaped groove 34, limiting the movement trajectory of the telescopic plate 18, preventing accidental deviation or falling, and evenly transferring the weight of the screen to the fixed plate 1 through the double support arms, increasing the load-bearing capacity and preventing the telescopic plate 18 loaded with the display from falling.

[0029] The lifting drive component 4 includes synchronous pulleys 41 mounted at both ends of the telescopic plate 18. A synchronous belt 42 is sleeved between the two synchronous pulleys 41. A transmission seat 44 is mounted on one long side of the synchronous belt 42, and the transmission seat 44 is connected to the lifting plate 40. An adjusting shaft 43 is coaxially mounted on one of the synchronous pulleys 41, and the adjusting shaft 43 extends outward. A transmission rod 45 is arranged along the length direction of the telescopic plate 18. A first bevel gear 46 is mounted at the end of the transmission rod 45, and a second bevel gear 47 that meshes with the first bevel gear 46 is mounted at the outer end of the adjusting shaft 43. When it is necessary to adjust the height of the lifting plate 40, the transmission rod 45 is rotated, causing the first bevel gear 46 and the second bevel gear 47 to mesh and drive each other. The adjusting shaft 43 rotates, driving the synchronous belt 42 to move. The synchronous belt 42 drives the lifting plate 40 to move through the transmission seat 44, thereby realizing the lifting movement of the lifting plate 40.

[0030] In addition, the telescopic plate 18 is equipped with a lifting motor. The lifting motor has a large torque, and once the lifting plate 40 is raised to the required height, it can be held in place and will not fall.

[0031] In addition, the telescopic plate 18 has a guide sliding groove 48 formed along its length on its side, and the lifting plate 40 is equipped with a guide slider 49 that slides in cooperation with the guide sliding groove 48, which can ensure the lifting movement of the lifting plate 40. In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0032] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
