[0023] In order to facilitate the understanding of the utility model, the following will be combined with the drawings and specific embodiments, the utility model is explained in more detail. The drawings show the preferred embodiments of the utility model. However, the utility model can be realized in many different forms, and is not limited to the embodiments described in the specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on another element or there can be a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or a middle element can exist at the same time. The terms "fixed", "integrally formed", "left", "right" and similar expressions used in the specification are only for the purpose of illustration, and in the drawings, similar units are indicated by the same reference numerals.

[0025] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0026] Example 1 Figures 1-4 As shown, when the display screen body 2 needs maintenance or replacement, press the controller 11. The controller 11 controls the motor in the drive assembly 5 to rotate forward. The motor drives the gear 51 to rotate. Due to the engagement relationship between the gear 51 and the rack 42, the lifting frame 4 with the rack 42 is lowered. The lifting frame 4 drives the display screen body 2 to move down to the designated position for maintenance through the connecting frame 43.

[0027] After maintenance is completed, the motor is reversed by the controller 11, causing the lifting frame 4 to rise, thereby moving the display screen body 2 to the initial position.

[0028] Example 2: In order to ensure that the lifting frame 4 does not sway during the up and down movement, two grooves 3 are provided on the two corresponding inner walls of the support; a first crack 32 is provided on one side of the groove 3, and the size of the extension 41 on the outside of the lifting frame 4 matches the size of the first crack 32; this ensures that the extension 41 on the outside of the lifting frame 4 can move within the groove 3, thereby ensuring the stability of the lifting frame 4.

[0029] Furthermore, due to the excessive size and weight of the outdoor display screen, accidents may occur during its upward or downward movement, necessitating a reduction in the movement speed of the lifting frame; therefore, buffer blocks 31 are installed on both sides of the upper end of the first crack 32.

[0030] Furthermore, in order to slow down the movement of the lifting frame and ensure the safety of the outdoor display screen during the descent or ascent, so that the display screen body is always on the support 1, a second slit 6 is provided on one side of the support 1, and a telescopic plate is installed in the second slit 6; the bottom of the telescopic plate is fixed to the bottom of the second slit 6, and the top of the telescopic plate is fixed to the bottom of the display screen body 1.

[0031] The bottom of the outdoor display screen is always within the second crack 6 of the bracket 1, and the telescopic plate also provides a cushioning effect.

[0032] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
