DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Please refer to Figure 1 The commercial LED display screen in the embodiment comprises a box 1 and a display screen main body 3 arranged above the box 1, an adjusting disc 5 is rotatably connected to the inner wall of the inner cavity of the box 1 and close to the top of the box 1, the adjusting mechanism 2 for the rotation of the display screen main body 3 is arranged in the box 1, and the stabilizing mechanism 4 for the stability of the box 1 is arranged in the box 1.

[0023] Four grooves are formed in the bottom of the box 1, and the wheel group 6 is arranged in the bottom of the box 1.

[0024] It is understood that the commercial LED display screen is transported to a commercial plaza or other commercial area by a transport device, and then moved to the area where it needs to be placed using the wheel set 6. The wheel set 6 is then self-locked using its self-locking device. Existing wheel sets 6 generally have a self-locking function, which is a well-known technology known to those skilled in the art, so this application will not elaborate on it further.

[0025] Please see Figure 2 In this embodiment, the adjustment mechanism 2 includes a first electric push rod 203 and a mounting cylinder 202 fixed at the center of the bottom of the adjustment disk 5. A connecting plate 204 is fixed to the outer side of the output shaft of the first electric push rod 203. Two cylinders 205 are vertically fixed to the upper surface of the adjustment disk 5. Connecting blocks 206 slide vertically between the front and rear side walls of the inner cavities of the two cylinders 205. A fixing post 207 is fixed to the top of each of the two connecting blocks 206. A motor 208 is fixed to the inner bottom wall of the housing 1. A first gear 209 is fixed to the outer side of the output shaft of the motor 208. A second gear 210 meshes with the outer side of the first gear 209.

[0026] The bottom of the mounting cylinder 202 is rotatably connected to the inner bottom wall of the housing 1 via a bearing, with a connecting column 201. The mounting cylinder 202 is located outside the first electric push rod 203. The two connecting blocks 206 are fixed to the upper surface of the connecting plate 204 by bolts and are located near its left and right ends respectively. The display body 3 is fixed to the top of the two fixing columns 207. The second gear 210 is fixed to the outside of the mounting cylinder 202. The outer diameter of the second gear 210 is larger than the outer diameter of the first gear 209. By activating the first electric push rod 203, the display body can be moved up and down to adjust its height, making it easier for more people to view.

[0027] It is understandable that by starting the motor 208, the first gear 209 can drive the second gear 210 to rotate, causing the mounting cylinder 202 to rotate, which in turn causes the display screen body 3 to rotate and adjust the angle, thus improving practicality.

[0028] Please see Figures 3-4 In this embodiment, the stabilizing mechanism 4 includes a second electric push rod 401 fixed to the bottom wall of the housing 1. A disc 402 is fixed to the outside of the output shaft of the second electric push rod 401. Four columns 403 are vertically fixed to the lower surface of the disc 402. A base plate 404 is fixed to the bottom end of each of the four columns 403.

[0029] The left and right side walls of the inner cavity of the housing 1 are fixed with slide rails, and the left and right ends of the disc 402 are fixed with positioning blocks that slide perpendicularly to the slide rails. By activating the second electric push rod 401, the disc 402 is moved downward, so that the chassis 404 contacts the ground, improving the stability of the equipment. At the same time, the audience can watch through the main body of the display screen 3. The upper surface of the disc 402 is provided with a slot that extends to its lower surface. The slot can avoid contact with the second gear 210.

[0030] Understandably, activating the second electric push rod 401 moves the disc 402 downward, bringing the chassis 404 into contact with the ground, thus improving equipment stability. Simultaneously, viewers can view the screen through the main body 3. Activating the first electric push rod 203 allows the main body of the display to be moved up and down to adjust its height for easier viewing. Activating the motor 208 causes the first gear 209 to drive the second gear 210 to rotate, causing the mounting cylinder 202 to rotate, which in turn allows the main body 3 of the display to rotate and adjust its angle, improving practicality.

[0031] All electrical components mentioned in this article are electrically connected to the main controller and power supply, and all electrical components mentioned are conventional and known devices. This application will not elaborate further. The main controller can be a conventional and known device such as a computer that performs control. The control circuit of the main controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so this utility model will not explain the control method and circuit connection in detail. At the same time, any parts of this utility model that are not described in detail are all common technologies known to those skilled in the art.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The working principle of the above embodiments is as follows:

[0034] When the commercial LED display screen is needed, it is transported to a commercial plaza or other commercial area by a transport device. Then, it is moved to the desired placement area using wheel set 6. The wheel set 6 is then self-locked using its self-locking device. By activating the second electric push rod 401, the disc 402 is moved downwards, so that the chassis 404 contacts the ground, improving the stability of the equipment. At the same time, viewers can view the screen through the main body 3. By activating the first electric push rod 203, the main body of the display screen can be moved up and down to adjust its height, making it easier for more people to view. By activating the motor 208, the first gear 209 drives the second gear 210 to rotate, causing the mounting cylinder 202 to rotate, which in turn causes the main body 3 of the display screen to rotate and adjust its angle, improving its practicality.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
