[0035] Embodiment 2

[0036] like Figure 1-8 As shown, this embodiment is basically the same as the first embodiment. Preferably, in order to better protect the outdoor display screen and the internal electronic components and prevent the outdoor display screen from malfunctioning or even causing a fire due to a harsh working environment, a basic chassis 1 is provided here including a support pillar 101 and a locking piece. The support pillar 101 includes two sections of a column, and the two sections of the column can be raised and lowered and adjusted. The locking piece is provided at the connection between the two sections of the support pillar 101. The outer side of the column located below the support pillar 101 is provided with reinforcing ribs to help increase the supporting stability of the support pillar 101.

[0037] The protective shielding mechanism includes a shielding plate 7, an adjustable ceiling 8 and protective side blocks 9. The shielding plate 7 is arranged on the inner side of the load-bearing frame 2, so that the shielding plate 7 can shield the side wall of the load-bearing frame 2 where the display screen is placed. The adjustable ceiling 8 is arranged at the end of the shielding plate 7, and the adjustable ceiling 8 is located directly above the load-bearing frame 2. The protective side blocks 9 are arranged on both sides of the shielding plate 7, and the protective side blocks 9 are arranged in contact with the outer wall at the edge of the load-bearing frame 2.

[0038] The adjustable ceiling 8 includes a guide bracket 801, an extendable soft canopy and a pulling member 802. The guide bracket 801 is arranged on both sides of the end of the shielding plate 7, and the guide bracket 801 is horizontally placed at the end of the load-bearing frame 2. The extendable soft canopy is slidably installed on the guide bracket 801. The pulling member 802 is arranged on the guide bracket 801, and the pulling member 802 acts on the extendable soft canopy, so that the extendable soft canopy can be extended and folded on the guide bracket 801 to achieve the adjustability of the ceiling. The pulling member 802 includes a pull rope and an arc block for positioning the pull rope. One end of the pull rope is connected to the moving end of the extendable soft canopy, and the other end passes around the arc block and hangs down, so that the pull rope can be pulled from under the guide bracket 801 and drive the extendable soft canopy to extend.

[0039] The extendable soft shed includes a sliding frame 803 and a leak-proof soft shed 804. The two sections of the sliding frame 803 are respectively slidably mounted on the guide brackets 801 on both sides of the end of the baffle plate 7. The pulling member 802 is connected to the sliding frame 803. The leak-proof soft shed 804 is a shed body made of soft fabric, and its own structure is relatively soft. One end of the leak-proof soft shed 804 is fixedly arranged between the two guide brackets 801 by an axis rod, and the other end is connected to the sliding frame 803, so that when the sliding frame 803 slides along the guide bracket 801, it can drive the two ends of the leak-proof soft shed 804 to move closer or farther, thereby realizing the extension and folding of the leak-proof soft shed 804.

[0040] In this embodiment, when in use, after the outdoor display screen is placed on the inner side of the load-bearing frame 2, the support pillars 101 are used to support the load-bearing frame 2 away from the ground, effectively preventing the moisture on the ground from affecting the outdoor display screen. The shielding plate 7 can be used to protect the rear of the display screen. At the same time, the protective side baffles 9 play a shielding role on the sides of the load-bearing frame 2, and the adjustable ceiling 8 plays a shielding role at the end of the load-bearing frame 2. When it is necessary to adjust the shielding area of ​​the adjustable ceiling 8, the pull rope part of the pulling member 802 can be pulled to pull the sliding frame 803 to slide along the guide bracket 801. At this time, the sliding frame 803 will drive the two ends of the leak-proof soft canopy 804 to move closer or farther away, thereby realizing the extension and folding of the leak-proof soft canopy 804. By controlling the shielding area of ​​the leak-proof soft canopy 804 in this way, the outdoor display screen and the internal electronic components can be effectively prevented from getting wet or damp, thereby better protecting the outdoor display screen.
