[0028] In this embodiment, the sliding block 12 has an "L" shape, and the telescopic block 13 has a "T" shape. The pull rod 6 forms a positioning structure between the sliding block 12 and the telescopic block 13 and the positioning frame 7. When working, the positioning spring 11 drives the sliding block 12 at the top of the sliding block 10 to engage with the telescopic block 13 through its own elastic force, thereby realizing the positioning operation of the pull rod 6. Example

[0029] like Figure 6 and Figure 7 As shown, the present invention proposes a liquid crystal screen housing. Compared with Example 1, as another embodiment of the present invention, the outer wall of the housing 1 is provided with a heat dissipation hole 14. One side of the heat dissipation hole 14 is located on the outer wall of the housing 1 and is fixedly connected to a mounting frame 15. The inner wall of the mounting frame 15 is penetrated by a threaded rod 16. The top of the threaded rod 16 is fixedly connected to a knob 17. The outer wall of the threaded rod 16 is threadedly connected to a lifting slider 18. The side wall of the lifting slider 18 is screwed with a connecting rod 19. The bottom end of the connecting rod 19 is screwed with a mounting block 20. The inner wall of the mounting block 20 is embedded with a mounting The mounting column 21 and the mounting block 20 are provided with a mounting groove 22. One end of the mounting column 21 is fixedly connected to the mounting plate 23. During operation, the lifting slider 18 slides to drive the two sets of connecting rods 19 to move synchronously, so that the lifting slider 18 slides through the connecting rods 19 to drive the mounting block 20 to slide along the inner wall of the mounting frame 15, so that the spacing between the mounting grooves 22 inside the mounting block 20 is equal to the spacing between the two sets of mounting columns 21. Then, the mounting column 21 is embedded in the mounting block 20 through the mounting groove 22 to achieve quick installation operation of the casing 1.

[0030] In this embodiment, two groups of connecting rods 19 are provided, and the mounting block 20 forms a sliding structure with the mounting frame 15 through the lifting slider 18 and the connecting rod 19. During operation, the lifting slider 18 slides to drive the two groups of connecting rods 19 to move synchronously, so that the lifting slider 18 slides through the connecting rod 19 to drive the mounting block 20 to slide along the inner wall of the mounting frame 15, thereby realizing the control operation of the sliding of the mounting block 20.

[0031] In this embodiment, the mounting posts 21 have a stepped shape, and the mounting frame 15 forms a snap-fit ​​structure with the mounting plate 23 through the mounting posts 21 and the mounting grooves 22. During operation, the spacing between the mounting grooves 22 inside the mounting block 20 is equal to the spacing between the two groups of mounting posts 21. Then, the mounting posts 21 are embedded in the mounting block 20 through the mounting grooves 22, thereby realizing a quick installation operation on the housing 1.

[0032] Working principle: First, the casing 1 is installed. The staff installs the mounting plate 23 on the wall. Then, the knob 17 is turned. The rotation of the knob 17 drives the lifting slider 18 to slide through the threaded rod 16. The sliding of the lifting slider 18 drives the two sets of connecting rods 19 to move synchronously, so that the lifting slider 18 slides through the connecting rods 19 to drive the mounting block 20 to slide along the inner wall of the mounting frame 15, so that the spacing between the mounting grooves 22 inside the mounting block 20 is equal to the spacing between the two sets of mounting columns 21. Then, the mounting columns 21 are embedded in the mounting block 20 through the mounting grooves 22 to achieve quick installation of the casing 1.

[0033] Next, when the display screen 5 is on standby, it is necessary to perform a protective operation on the display screen 5. The user pulls the pull rod 6, and the movement of the pull rod 6 drives the protective cloth 3 to overcome the elastic force of the spring 2 and unfold it, thereby realizing the protective operation of the display screen 5. Then, the positioning spring 11 drives the sliding block 12 at the top of the sliding block 10 to engage with the telescopic block 13 through its own elastic force, thereby realizing the positioning operation of the pull rod 6.

[0034] Finally, when the display screen 5 is working, the user presses the pressure plate 8, and the movement of the pressure plate 8 drives the telescopic block 9 to move synchronously, so that the telescopic block 9 drives the sliding block 10 to overcome the elastic force of the positioning spring 11 and slide along the inner wall of the positioning frame 7. The sliding block 10 slides and drives the sliding block 12 away from the telescopic block 13, so that the mainspring 2 drives the protective cloth 3 to be reeled through its own elastic force, thereby realizing the automatic reeling operation of the protective cloth 3.
