Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 6 This illustration shows an embodiment of the present invention providing a windproof frame for a display screen, installed in an LED display screen housing 1. The windproof frame includes a main support rod 2, two first movable parts 3, and two second movable parts 4. The LED display screen housing 1 includes a first mounting position 5 and a second mounting position 6 with a predetermined spacing. The two first movable parts 3 are arranged side by side vertically, with one end of each connected to the upper and lower parts of the main support rod 2, respectively. The other end of each of the two first movable parts 3 is rotatably connected to the upper and lower parts of the first mounting positions 5, respectively. The two second movable parts 4 are arranged side by side vertically, with one end of each connected to the upper and lower parts of the first mounting positions 5, respectively. The upper and lower parts of the second mounting position 6 are rotatably connected. The first movable part 3 is provided with a latch 7, and the main support rod 2 is provided with a locking hole 8. When the windproof frame of the display screen is opened, the main support rod 2 rotates away from the LED display screen housing 1, and the other ends of the two second movable parts 4 are respectively locked with the main support rod 2 by inserting elastic pins into the locking holes 8. When the windproof frame of the display screen is closed, the main support rod 2 rotates towards the LED display screen housing 1, and the other ends of the two second movable parts 4 are respectively locked with the first movable part 3 by inserting elastic pins into the latch 7. It can be understood that in practical applications, the positions of the first movable part 3 and the second movable part 4 can be interchanged.

[0025] Specifically, the end of the first movable part 3 is provided with a sleeve 9, the main support rod 2 passes through the sleeve 9 and is fixed to the inner wall of the sleeve 9 by fasteners, the end of the second movable part 4 is provided with the elastic pin, and the sleeve 9 is provided with a through hole 10 corresponding to the lock hole 8. When the windproof frame of the display screen is opened, the elastic pin passes through the through hole 10 and locks with the lock hole 8.

[0026] More specifically, the end of the second movable member 4 is provided with a semi-circular claw portion 11. The semi-circular inner surface of the semi-circular claw portion 11 contacts the outer wall of the sleeve 9. The semi-circular claw portion 11 has a limiting groove 12 and a pin hole 13 communicating with the limiting groove 12. The elastic pin is installed in the limiting groove 12. The elastic pin includes an elastic element 14, an unlock button 15, and a pin element 16 extending into the pin hole 13. The unlock button 15 is fixed to the pin element 16. One end of the elastic element 14 acts on the pin element 16, and the other end acts on the semi-circular claw portion 11.

[0027] More specifically, the groove length direction of the limiting groove 12 is perpendicular to the rod length direction of the main support rod 2 so that the pin 16 can be vertically inserted into the locking hole 8 along the groove length direction, thereby locking the second movable member 4 with the main support rod 2.

[0028] More specifically, the insertion end of the pin 16 has a guide slope 17, which is used to guide the pin 16 into the lock hole 8.

[0029] Specifically, the latch 7 has a through hole 18. When the windproof frame of the display screen is retracted, the surface of the second movable member 4 facing the LED display screen housing 1 is in contact with the surface of the first movable member 3 facing away from the LED display screen housing 1. The center line of the through hole 18 coincides with the center line of the elastic pin so that the elastic pin can be aligned and inserted into the through hole 18, thereby locking the second movable member 4 and the first movable member 3.

[0030] In some specific embodiments, pressing the unlock button 15 retracts the pin 16 elastically, pushes the main support rod 2 inward so that the second movable part 4 fits against the first movable part 3, and the through hole 18 of the latch 7 automatically aligns with the pin 16. The insertion end of the pin 16 is inserted into the through hole 18 under the elastic force of the elastic member 14 to complete the closing and locking action. When it needs to be opened, pressing the unlock button 15 again retracts the pin 16 elastically, pushes the main support rod 2 outward, and drives the pin 16 at the end of the second movable part 4 to slide into the through hole 10 of the sleeve 9 along the guide slope 17. When the pin 16 is aligned with the lock hole 8, the elastic member 14 drives it to be inserted vertically to complete the locking. At this time, the first movable part 3, the second movable part 4 and the main support rod 2 form a stable triangular support structure.

[0031] Specifically, the first movable component 3 can be installed in the second mounting position 6, and the second movable component 4 can be installed in the first mounting position 5 of another adjacent LED display screen cabinet 1, so that the windproof frame of the display screen can be connected across the cabinet. The mounting structure of the first mounting position 5 is the same as the mounting structure of the second mounting position 6. The mounting structure includes a mounting base fixed to the LED display screen cabinet 1. The windproof frame of the display screen also includes a rotating connector. The first movable component 3 and the second movable component 4 can both be rotatably connected to the mounting base through the rotating connector.

[0032] Specifically, the main support rod 2 is vertically connected to the first movable part 3 and the second movable part 4 respectively, and the included angle between the first movable part 3 and the second movable part 4 when the display screen windproof frame is opened is between 90 degrees and 120 degrees.

[0033] Specifically, the windproof frame of the display screen also includes a secondary support assembly. The secondary support assembly has a T-shaped structure and includes a horizontal part 19 and a vertical part 20 that is perpendicularly connected to the horizontal part 19. The two ends of the horizontal part 19 are respectively connected to the middle of the two first movable parts 3, and the vertical part 20 is connected to the middle of the first mounting position 5.

[0034] An LED display cabinet includes a left middle frame and a right middle frame located inside the cabinet frame. The left middle frame and the right middle frame are respectively connected to the windproof frame of the display screen. The left middle frame is the first mounting position 5, and the right middle frame is the second mounting position 6.

[0035] In summary, this type of windproof display frame achieves rapid opening and closing of the windproof frame through the cooperation of elastic pins and locking holes 8 or elastic pins and locking buckles 7, resulting in high work efficiency and convenient use. This type of windproof display frame rotatably connects one end of the first movable part 3 and one end of the second movable part 4 to the left and right middle frames inside the LED display cabinet 1, so that the first movable part 3 and the second movable part 4 can be installed in the same LED display cabinet 1 to support a single display cabinet, or they can be set in different adjacent LED display cabinets 1 to achieve cross-cabinet connection to support two display cabinets, making it flexible in use and highly practical.

[0036] It should be noted that this utility model is not limited to the above-described embodiments. Based on the inventive spirit of this utility model, those skilled in the art can make other changes, and these changes made based on the inventive spirit of this utility model should be included within the scope of protection claimed by this utility model.
