[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a multimedia playback device based on an LED screen, comprising a base 1, and a table top 2 is arranged above the base 1.

[0022] The table top 2 includes a Z-shaped folding frame 201, a motor 202 is plugged into the top of the Z-shaped folding frame 201, a first reel 203 is plugged into the output shaft of the motor 202, a V-shaped folding plate 204 is welded to the connecting plate of the first reel 203, a waterproof cloth 205 is plugged into one side of the first reel 203, a second reel 206 is glued to the iron sheet on the other side of the V-shaped folding plate 204, and an LED multimedia screen body 207 is provided above the table top 2.

[0023] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the base 1 includes a fixed plate 106, a sliding rod 102 is inserted inside the fixed plate 106, a slider 107 is inserted on one side of the sliding rod 102, a threaded rod 105 is meshed with the internal thread of the slider 107, a rotating handle 104 is welded on one side of the threaded rod 105, a pulley 101 is installed at the bottom of the base 1 by screws, a cross-folding plate 103 is inserted on one side of the slider 107 by a pin, and the slider 107 forms a sliding structure with the sliding rod 102 through the threaded rod 105; because the existing LED screen playback equipment is generally used for commercial activities, but the existing LED screen is a whole screen, and it is a fixed screen, which needs to be installed by screws and cannot be adjusted in height, now the improvement is that the threaded rod 105 is driven to rotate by rotating the handle 104, and the threaded rod 105 drives the slider 107 to move on the sliding rod 102, and different heights can be adjusted, which is convenient for quick installation, thereby achieving the adjustment function of the slider 107.

[0024] In this embodiment, Figure 1, Figure 2 and Figure 3 As shown, the table top 2 forms a telescopic structure through the cross-folding plate 103 and the slider 107; because the existing LED screen playback equipment is generally used for commercial activities, some places need LED screen playback equipment, which is generally built on site. It is inconvenient to install and disassemble, resulting in too many items to carry and inconvenient to carry. Now the improved slider 107 allows one side plate of the cross-folding plate 103 to be moved to adjust the height of the upper table top 2, which is convenient for quick storage and carrying later, thereby achieving the purpose of adjusting the height of the table top 2.

[0025] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, a plurality of Z-shaped folding frames 201 are provided above the table top 2, and a Z-shaped folding frame 201 is provided between the table top 2 and the first reel 203, a Z-shaped folding frame 201 and another Z-shaped folding frame 201 are horizontally provided on the first reel 203, and a Z-shaped folding frame 201 is provided between the table top 2 and the LED multimedia screen body 207; the existing LED screen playback equipment is generally fixedly installed on the support frame, resulting in the need to disassemble the LED screen playback equipment and the support frame after use, resulting in inconvenience in installation, and now the improved waterproof cloth 205 is connected to the Z-shaped folding frame 201 and another Z-shaped folding frame 201 for folding storage, and the LED multimedia screen body 207 is connected to the Z-shaped folding frame 201 for folding storage, which is convenient for later storage and does not take up space, thereby achieving the effect of folding the Z-shaped folding frame 201.

[0026] In this embodiment, Figure 4 As shown, the first reel 203 forms a rotating structure through the motor 202; because the existing LED screen playback equipment is generally used for commercial activities, some outdoor activities may be easily damaged once it rains. Now the motor 202 is improved to rotate the first reel 203, so that the first reel 203 can tighten and unfold the waterproof cloth 205, thereby achieving the driving effect of the first reel 203.

[0027] In this embodiment, Figure 4 As shown, a first reel 203 and a second reel 206 are horizontally provided below the waterproof cloth 205; because the existing LED screen playback equipment is generally used for commercial activities, some outdoor activities may be affected by rainy weather, and the existing LED is generally not waterproof, so it cannot be used due to weather influence. Now the improved first reel 203 and the second reel 206 support the waterproof cloth 205 through the V-shaped folding plate 204, thereby achieving the supporting effect of the V-shaped folding plate 204.

[0028] The use method and advantages of the utility model: When the multimedia player based on the LED screen is used, the working process is as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, turn the handle 104 clockwise to rotate the threaded rod 105, so that the slider 107 drives the cross-folding plate 103 and the table 2 to move horizontally on the slide rod 102 in turn, pulls the first reel 203 upward vertically to drive the Z-shaped folding frame 201 to move, and the motor 202 drives the first reel 203 to rotate clockwise, so that the second reel 206 moves the waterproof cloth 205 horizontally through the V-shaped folding plate 204, and the LED multimedia screen body 207 moves vertically upward through the Z-shaped folding frame 201.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
