[0028] Example 1:

[0029] See also Figure 1 - Figure 7 A portable outdoor projection screen structure includes a screen body 1 and a plurality of mounting posts 3. The surface of the screen body 1 is provided with a plurality of mounting holes 2. The surface of the screen body 1 is provided with a mounting structure 4. The mounting structure 4 includes a round block 401. The round block 401 is located on one side of the screen body 1. The surface of the round block 401 is provided with a plurality of grooves 402. The grooves 402 are grouped in pairs. The inner walls of the two groups of grooves 402 are rotatably connected to a first support arm 403 and a second support arm 404. The plurality of mounting posts 3 are fixedly connected to the first support arm 403 and the second support arm 404 respectively. The surface of the round block 401 is rotatably connected to a rotating shaft 405. One end of the rotating shaft 405 is fixedly connected to There is a rotating plate 406, and the end of the rotating shaft 405 away from the rotating plate 406 is fixedly connected to the driving plate 407. The arc surface of the driving plate 407 is fixedly connected to several baffles 408. A card slot 409 is provided on one side of the baffle 408. A latch 410 slides through the surface of the rotating plate 406. Two circular grooves 411 are provided on the surface of the round block 401. The size of the circular groove 411 is adapted to the size of the latch 410. A rectangular groove 412 is provided at the end of the second support arm 404 away from the round block 401. An extension arm 413 is slidably inserted into the inner wall of the rectangular groove 412. One end of the extension arm 413 is fixedly connected to a pointed cone 414. A bolt 415 is threadedly connected to the surface of the second support arm 404. Rectangular holes 416 are formed on both sides of the second support arm 404, communicating with the rectangular slot 412. The end of the extension arm 413, away from the pointed cone 414, is fixedly connected to a limit plate 417, which slides into contact with the inner walls of the two rectangular holes 416. A spring 418 is sheathed around the arcuate surface of the latch 410, with its ends fixedly connected to the latch 410 and the rotating plate 406, respectively. Several limit arms 419 are fixedly connected to the arcuate surface of the circular block 401, with a circular plate 420 fixedly connected to the end of the limit arm 419 away from the circular block 401.

[0030] See also Figure 3The limiting structure 5 includes a limiting structure 5 provided on the surfaces of the first support arm 403 and the second support arm 404. The limiting structure 5 includes several extension plates 51, which are fixedly connected to the first support arm 403 and the second support arm 404 respectively. A threaded rod 52 is threaded through the surface of the extension plate 51. One end of the threaded rod 52 is fixedly connected to a turntable 54. One end of the threaded rod 52 is rotatably connected to a pressure plate 53. The size of the pressure plate 53 is adapted to the size of the mounting column 3. A guide plate 55 is slidably passed through the surface of the extension plate 51. The guide plate 55 is adapted to the size of the pressure plate 53.

[0031] Working principle: When the curtain body 1 needs to be unfolded, first pull the latch 410. The latch 410 moves and slides in the rotating plate 406 and gradually disengages from the circular groove 411. When the latch 410 moves, the spring 418 is stretched. After the latch 410 disengages from the circular groove 411, the rotating plate 406 is rotated. The rotation of the rotating plate 406 drives the rotating shaft 405 to rotate. The rotation of the rotating shaft 405 drives the driving plate 407 to rotate. The rotation of the driving plate 407 drives the baffle 408 to rotate. When the baffle 408 rotates, the first support arm 403 and the second support arm 404 gradually disengage from the slot 409. When the first support arm 403 and the second support arm 404 disengage from the slot 409, the first support arm 403 and the second support arm 404 are rotated. 404, the first support arm 403 and the second support arm 404 will rotate in the groove 402, and when the first support arm 403 and the second support arm 404 are rotated to a suitable angle, the first support arm 403 and the second support arm 404 will respectively fit with the surface of the circular plate 420, and the circular plate 420 reaches an angle that limits the rotation of the first support arm 403 and the second support arm 404, thereby facilitating the positioning of the first support arm 403 and the second support arm 404, and then continue to rotate the baffle 408, and when the baffle 408 is rotated to a suitable angle, the baffle 408 will respectively fit with the surface of the first support arm 403 and the second support arm 404, and the baffle 408 reaches a position that limits the first support arm 403 and the second support arm 404, thereby The first support arm 403 and the second support arm 404 are unfolded, and then the latch 410 is released. The latch 410 is inserted into the circular groove 411 with the help of the contraction force of the spring 418. The latch 410 reaches the limit of the rotation of the rotating plate 406, and then limits the rotation of the baffle 408, thereby limiting the first support arm 403 and the second support arm 404. At this time, the curtain body 1 is unfolded, and then the mounting hole 2 opened on the surface of the curtain body 1 is put on the mounting column 3, so that the curtain body 1 is unfolded and then limited. Then the bolt 415 is rotated. The rotation of the bolt 415 will move in the second support arm 404 with the help of the thread. When the bolt 415 moves to the appropriate position, the bolt 415 will be released from the squeeze on the extension arm 413, and then the cone 414 is pulled, and the cone 415 is pulled. The movement of the extension arm 413 will gradually cause the extension arm 413 to disengage from the rectangular slot 412. When the extension arm 413 moves, the limit plate 417 will slide in the rectangular slot 412. The rectangular slot 412 will limit the movement path of the limit plate 417, thereby limiting the movement path of the extension arm 413, thereby preventing the extension arm 413 from being disengaged from the rectangular slot 412 and being inconvenient to insert. When the extension arm 413 is moved out to a suitable length, the bolt 415 is rotated. The bolt 415 will move toward the extension arm 413 by means of the thread. The bolt 415 will abut against the surface of the extension arm 413. The bolt 415 reaches the position that limits the extension arm 413. At this time, hold the round block 401 and insert the two pointed cones 414 into the ground to unfold the curtain body 1 for use.

[0032] When it is necessary to improve the stability of the curtain body 1 on the mounting post 3, first rotate the turntable 54. The rotation of the turntable 54 will drive the threaded rod 52 to rotate. The rotation of the threaded rod 52 will move in the extension plate 51 with the help of the thread. The movement of the threaded rod 52 will drive the pressure plate 53 to move. When the pressure plate 53 moves, it will drive the guide plate 55 to slide in the extension plate 51. The guide plate 55 limits the movement path of the pressure plate 53, thereby preventing the pressure plate 53 from rotating when moving. During the movement, the pressure plate 53 will gradually be sleeved on the surface of the mounting post 3. The pressure plate 53 will be pressed against the surface of the curtain body 1, thereby squeezing the curtain body 1 against the surface of the mounting post 3, thereby improving the stability of the curtain body 1 installed on the mounting post 3.

[0033] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
