[0024] Embodiment 1

[0025] like Figure 4-6 As shown, in this embodiment, an adjusting rod 250 is rotatably connected to one side of the inner side surface of the support frame 210, a worm gear 271 is fixedly sleeved on one end of the connecting rod 270, two worms 251 are fixedly sleeved on the side of the adjusting rod 250 corresponding to the worm gear 271, and the worms 251 are meshed with adjacent worm gears 271 for transmission, and the two worms 251 rotate in opposite directions.

[0026] In this embodiment, after the DC screen body 100 is moved to the installation position, the adjusting rod 250 can be rotated, and the adjusting rod 250 can drive the two connecting rods 270 to rotate through the worm 251 and the worm wheel 271, and the connecting rod 270 can drive the rotating seat 231 to rotate in the fixed seat 230, so that the roller seat 232 rotates toward the inside of the support frame 210, and the roller seat 232 is retracted into the inside of the support frame 210, so that the roller seat 232 is separated from the ground, and the base frame 130 is gradually lowered, so that the bottom surface of the base frame 130 contacts the ground, and the DC screen body 100 is supported by the base frame 130. At this time, the position of the DC screen body 100 can be fixed. Since the rotation directions of the two worm gears 251 are opposite, the roller seats 232 on the two connecting rods 270 can rotate in opposite directions, so that the DC screen body 100 can fall vertically smoothly.

[0027] like Figure 5-6As shown, in this embodiment, the side of the connecting rod 270 corresponds to the fixed seat 230 and is rotatably connected to two limit plates 240, and the bottom of the two limit plates 240 located on the same connecting rod 270 are fixedly connected to abutment blocks 241, and the sides of the abutment blocks 241 are in contact with the sides of the adjacent roller seats 232. The side of the connecting rod 270 is located between the two limit plates 240 and is rotatably connected to a linkage rod 280, and both ends of the linkage rod 280 are fixedly connected to the sides of the adjacent limit plates 240. A worm gear 281 is fixedly sleeved on the side of the linkage rod 280, and an adjusting rod 260 is rotatably connected to the inner side of the support frame 210 corresponding to the worm gear 281, and two worm gears 261 that mesh with the adjacent worm gear 281 are fixedly sleeved on the side of the adjusting rod 260.

[0028] In the specific implementation, the adjusting rod 260 can be rotated, and the adjusting rod 260 can drive the linkage rod 280 to rotate through the worm 261 and the worm gear 281, and the linkage rod 280 can drive the limit plate 240 to rotate upward, so that the limit plate 240 drives the abutment block 241 to rotate, and the abutment block 241 is staggered with the roller seat 232. At this time, the roller seat 232 can rotate relative to the rotating seat 231, so that the DC screen body 100 can be pushed in any direction. When it is necessary to retract the roller seat 232 into the support frame 2 When 10, the adjusting rod 260 can be rotated in the opposite direction to rotate the abutting block 241 downward, the abutting block 241 abuts against the roller seat 232, and pushes the adjacent roller seat 232 to rotate. After the abutting block 241 abuts against the side of the roller seat 232, the roller seat 232 can be rotated to the original angle, and the abutting block 241 can limit the rotation of the roller seat 232 again, so that the rotating seat 231 drives the roller seat 232 to rotate relative to the fixed seat 230, and the roller seat 232 is retracted into the support frame 210.

[0029] Embodiment 2

[0031] During specific implementation, the fixing plate 220 can be connected to the base frame 130 by the limiting screw rod 221, so that the base frame 130 can be fixed on the support frame 210, which is convenient for the support module 200 to support the DC screen body 100. The limiting rod 132 can limit the fixing plate 220. After the limiting screw rod 221 is screwed out, the base frame 130 and the connecting plate 131 are supported by the ball bearings. In this way, after the support module 200 is moved to the installation position, the base frame 130 can move on the ball bearings, which is convenient for fine-tuning the installation angle and position of the DC screen body 100, which is beneficial to the placement and installation of the DC screen body 100.
