Description

Technical Field

[0001] The invention relates to the technical field of protective equipment, and in particular to a supporting and protective mechanism and method for an outdoor large-scale spliced ​​display. Background Art

[0002] Spliced ​​display is an industrial display that uses liquid crystal splicing technology to achieve splicing. The biggest feature is that it can be freely spliced ​​and combined into a larger display. Therefore, it is widely used in various industries, such as hydropower production scheduling, military command, urban management, mining safety, environmental monitoring, fire meteorology and maritime affairs, government and enterprise video conferencing, financial securities, airports, subways, shopping malls, hotels, communication information, theaters, stadiums, exhibitions, gatherings, concerts, parties, media advertising and other display systems, as well as commercial leasing of display equipment. In the equipment application of spliced ​​display, a protective mechanism will be set on the display to reduce the damage or failure rate of the display.

[0003] For example, the prior art CN116312273B proposes an all-round protective assembly for an LED billboard that is easy to disassemble, comprising an LED screen body, a support column rotatably mounted on the bottom of the LED screen body, a base fixedly mounted on one end of the support column away from the LED screen body, and a first motor fixedly mounted on the side of the base away from the support column. The device can protect the display screen by providing an movable protective cover.

[0004] However, the above-mentioned equipment still has certain defects in practical application. Although the existing technology can protect the display screen by shielding, this method does not have wind resistance. In the application of large-scale displays, the display screen is exposed to a large area, and the setting of the protective cover will further increase the area exposed to the wind. Therefore, it is very easy to be damaged in severe weather such as strong winds and hail. In view of the above problems, we provide a support and protection mechanism and method for outdoor large-scale spliced ​​displays to solve the problems existing in the existing technology.

[0054] The working principle of the present invention is: when working, the driving motor 601 drives the second synchronous belt 602 and the third synchronous wheel 603 to operate, the third synchronous wheel 603 rotates to drive the driving shaft 604 to rotate, the driving shaft 604 rotates to drive the first bevel gear 606 to rotate, the first bevel gear 606 rotates to drive the third bevel gear 608 to rotate, the third bevel gear 608 rotates to drive the side connecting shaft 609 to rotate, the side connecting shaft 609 rotates to drive the second bevel gear 607, the second bevel gear 607 rotates to drive the second screw rod 704 to rotate, the second screw rod 704 rotates to drive the top threaded block 701 to move upward, the top threaded block 701 moves upward, it will drive the connecting rod 706 to move, the movement of the connecting rod 706 will drive the first gear 707 to rotate, so that multiple intermediate sliders 70 5. When the top threaded block 701 moves to the top, the unfolding is completed. At the same time, the L-shaped mounting rod 702 drives the screen mounting plate 703 to form a vertical plane, so as to realize the splicing of the spliced ​​screen 7031 and form a large-area display screen. When unfolding, the driving shaft 604 also drives the second synchronous belt 3083 to rotate, and the second synchronous belt 3083 rotates to drive the first synchronous belt 3082, and the first synchronous belt 3082 drives the first synchronous wheel 3081, and the first synchronous wheel 3081 rotates to drive the first screw rod 308, and the first screw rod 308 rotates to drive the unfolding rod 310 to move to the end of the front arm 302, and then the rainproof sunshade cloth 301 is pulled to unfold, and then the traction rope 306 rotates to drive the first winding roller 207 to rotate, and the PET high-transmittance film 202 is put down to protect the spliced ​​screen 7031;

[0055] When encountering severe weather such as strong winds or hail, the PET high-transmittance film 202 is first rolled up, and then the driving assembly 600 drives the second screw rod 704 to rotate in the opposite direction. The rotation of the second screw rod 704 drives the top threaded block 701 to move. When the top threaded block 701 moves downward, the first gear 707 at the lower end of the top threaded block 701 rotates under the action of the connecting rod 706. The rotation of the first gear 707 at the lower end drives the first gear 707 at the upper end to rotate, and then drives the L-shaped mounting rod 702 to rotate. The rotation of the L-shaped mounting rod 702 turns the screen mounting plate 703 into an inclined state. At the same time, the downward movement of the top threaded block 701 will drive the connecting rod 706 to gradually reduce the distance between the middle sliders 705, and finally the screen mounting plate 703 will be stored in the protective box 102 for protection. At the same time, the first screw rod 308 will also reverse at the same time, so that the unfolding rod 310 moves toward the winding wheel 303. At the same time, the winding wheel 303 rotates under the action of the gravity of the traction rope 306 and the counterweight slider 304 to wind the retracted rainproof sunshade cloth 301 around the second winding roller 307 to complete the winding, so as to prevent the rainproof sunshade cloth 301, the PET high-transmittance film 202 and the spliced ​​screen 7031 from being damaged by bad weather.
