Description

Technical Field

[0001] This utility model relates to the field of conference display technology, specifically to an LED display screen for conference presentations. Background Technology

[0002] A conference display screen is a large display device used in conference rooms. It can be used to display various information such as computer signals, video signals, and image signals, making it convenient for participants to view and communicate. There are various types of conference display screens, such as LCD video walls, LED full-color displays, and conference flat-panel TVs. Each of them has its own advantages and disadvantages and is suitable for different occasions and needs.

[0003] The utility model with publication number CN217843202U discloses a display screen bracket for conference room information display, including a support base, a support frame fixedly installed at the edge of the upper surface of the support base, a mounting frame fixedly installed at the upper end of the support frame, a display screen positioning strip fixedly installed on the front surface of the mounting frame, and an auxiliary device suspended above the support base.

[0004] The above technical solution uses two anti-detachment clamping arms to hold the display screen under the action of rebound force. The anti-detachment clamping arms, together with the storage tray, can conveniently support the display screen during installation, eliminating the trouble of manual lifting and thus adapting to single-person installation work. During use, the storage tray slides on the surface of the support frame through the guide sleeve and adjusts its height, facilitating convenient subsequent placement and retrieval of items. However, the display angle of the display screen cannot be adjusted and fixed after installation, and the corners of the display screen are easily damaged by external impacts, affecting its continued use. Utility Model Content

[0005] The purpose of this invention is to provide an LED display screen for conference presentations, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An LED display screen for conference presentations includes a lifting column and a screen protector assembly connected near the top of the lifting column. The lifting column includes a support column and an electric lifting rod inside the support column. A T-slot is provided at the top of the support column, and a lifting block is provided in the T-slot. The screen protector assembly includes two fixed housings arranged in a cross shape. Each fixed housing has two extension frames inside. Several racks are evenly spaced on the inner side of each extension frame. A gear meshes with the two racks inside the same fixed housing. One end of each extension frame has a limiting block and the other end has a corner protector. A back plate is provided on the front side of the front fixed housing, and a screen is provided on the front side of the back plate.

[0008] The screen protector assembly has a hinge seat in the middle of the fixed shell at the rear end, and a connecting block at the rear end of the hinge seat. The rear end of the connecting block is welded and fixed to the lifting block, and a storage component is provided at the bottom end of the lifting column.

[0009] Preferably, the bottom end of the electric lifting rod is fixed to the bottom of the support column by screws, the lifting block is welded to the top of the telescopic arm of the electric lifting rod, and the width of the inner wall of the T-slot is adapted to the width of the outer wall of the lifting block.

[0038] In this utility model, the electric lifting rod 33 is electrically connected to an external power source through a wire, and the control switch on the outer wall of the electric lifting rod 33 is activated to extend or shorten the telescopic arm of the electric lifting rod 33, thereby enabling the lifting block 31 to slide along the vertical direction of the T-slot 34.

[0039] Furthermore, the bottom of the lifting column 3 is provided with a storage component 4, which includes a cabinet 41 and a drawer 42 fitted inside the cabinet 41. The drawer slot of the cabinet 41 is adapted to the size of the drawer 42.

[0040] In this utility model, the drawer slot cooperates with the drawer 42 to make the drawer 42 easy to open and close, and the cabinet body 41 has two drawers 42 set up inside the upper and lower parts to facilitate classified storage.

[0041] Specifically, the lifting column 3 is welded and fixed to the storage component 4, and the bottom of the cabinet 41 is provided with a counterweight 43, which is welded and fixed to the bottom of the cabinet 41.

[0042] In this invention, welding and fixing increase the structural stability of the lifting column 3 and the storage component 4, and the counterweight 43 stabilizes the overall center of gravity, preventing the top gravity from pressing down and causing it to tip over, thus affecting the overall use of the meeting.

[0043] It should be noted that the screen protection assembly 2 includes two fixed housings 23, which are arranged in a cross shape. Each fixed housing 23 has two extension brackets 24 inside. Each extension bracket 24 has several racks 29 evenly distributed on its inner side. A gear 26 meshes with the two racks 29 inside the same fixed housing 23. One end of the extension bracket 24 has a limiting block 25 and the other end has a corner guard 27. A back plate 28 is located on the front side of the front fixed housing 23.
