[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0024] Example 1
[0025] Refer to attached figure Figure 1- Appendix Figure 3 This is the first embodiment of the present invention, which provides a large-screen display device, including a base 1, a display device 2, a protective structure 3, and a fixing structure 4. The display device 2 and the protective structure 3 are respectively installed on the base 1, and the fixing structure 4 is installed on the protective structure 3. The display device 2 includes a display screen 21, a protective frame 22, a support rod 23, and a support block 24. The protective frame 22 is installed on the outside of the display screen 21 to protect the display screen 21. The support rod 23 is fixedly installed at the bottom end of the protective frame 22, and the support block 24 is fixedly installed at the bottom end of the support rod 23 to support the display screen 21.
[0026] The protective structure 3 includes a protective shell 31, a guide rail 32, a limiting plate 33, a one-way screw 34, and a motor 35. The protective shell 31 is fixedly installed on the top of the base 1 to protect the display screen 21. The guide rail 32 is fixedly installed on both sides of the top of the base 1. The limiting plate 33 is fixedly installed on the top of the base 1 and on one side of the guide rail 32. The one-way screw 34 is rotatably installed between the protective shell 31 and the limiting plate 33 and is located between the guide rail 32. The motor 35 is fixedly installed on the outside of the protective shell 31, and the motor shaft of the motor 35 is fixedly connected to one end of the one-way screw 34. A mounting plate 36 is threaded on the one-way screw 34. Both ends of the mounting plate 36 are clamped on the guide rail 32, and the mounting plate 36 and the guide rail 32 are slidably connected. A limiting groove 37 is provided at the top of the mounting plate 36, and the support block 24 is inside the limiting groove 37.
[0027] During use, when it is necessary to view the display screen 21, the motor 35 is started. The motor shaft of the motor 35 drives the one-way screw 34 to rotate. The one-way screw 34 controls the mounting plate 36 to slide on the guide rail 32. The mounting plate 36 drives the display screen 21 to move, so that the display screen 21 slides out of the protective shell 31 for people to view. After viewing, the motor 35 reverses, so that the mounting plate 36 moves into the inside of the protective shell 31, so that the display screen 21 enters the protective shell 31 and is protected by the protective shell 31.
[0028] Example 2
[0029] Refer to attached figure Figure 4 and attached Figure 5 This is the second embodiment of the present invention, which differs from the first embodiment in that:
[0030] The fixed structure 4 includes a fixed frame 401, a drive box 402, a rotating seat 403, and a connecting rod 406. The fixed frame 401 is fixedly installed on the top of the mounting plate 36 and covers the limiting groove 37. The drive box 402 is fixedly installed on one side of the fixed frame 401. The rotating seats 403 are configured as a pair and are respectively fixedly installed on the mounting plate 36. A bidirectional lead screw 404 is rotatably installed between the rotating seats 403. The bidirectional lead screw 404 passes through the drive box 402 and is rotatably connected to the drive box 402. A threaded block 405 is threadedly installed on the bidirectional lead screw 404. A limiting rod 407 is fixedly installed on the connecting rod 406. The limiting rod 407 passes through the side wall of the fixed frame 401 and extends into the interior of the fixed frame 401. The limiting rod 407 and the fixed frame 401 are slidably connected. The support block 24 is provided with a limiting hole 411 that matches the limiting rod 407. The connecting shaft 409 is rotatably installed on the drive box 402. The bottom end of the connecting shaft 409 is fixedly installed with a first bevel gear 408. The top end of the connecting shaft 409 is fixedly installed with a turntable. The bidirectional lead screw 404 is fixedly installed with a second bevel gear 410. The second bevel gear 410 and the first bevel gear 408 mesh with each other.
[0031] During use, when the support block 24 is inserted into the limiting groove 37, the limiting hole 411 and the limiting rod 407 are aligned. Rotating the turntable causes the first bevel gear 408 to rotate via the connecting shaft 409. The first bevel gear 408 then drives the bidirectional lead screw 404 to rotate via the second bevel gear 410. The bidirectional lead screw 404 drives the threaded block 405 to slide, causing the threaded block 405 to move relative to the support block. The threaded block 405 then drives the limiting rod 407 to slide via the connecting rod 406, thereby extending the limiting rod 407 into the limiting hole 411. This limits and fixes the support block 24, ensuring that the support block 24 is stably installed inside the limiting groove 37. By rotating the turntable, the limiting rod 407 can slide, thus limiting and releasing the support block 24, facilitating the installation and removal of the display screen 21.
[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
