[0028] The vertical support frame 3 is symmetrically arranged on the left and right sides above the central fixed guide rail 101. The bottom of the vertical support frame 3 is connected with a translation base 301. The vertical support frame 3 is slidably connected to the central fixed guide rail 101 through the translation base 301.

[0029] The tilt projection frame 102 is arranged on the upper front side of the central base 1, and a projector 103 is installed in the middle of the tilt projection frame 102;

[0030] The storage reel 4 is vertically arranged in the middle of the inner side of the vertical support frame 3, and a winding opening 401 is arranged on the adjacent side of the storage reel 4 symmetrically arranged on the left and right sides, and a winding reel 402 is rotatably connected inside the storage reel 4, and a projection soft screen 404 is wound around the outer side of the winding reel 402, and the left and right ends of the projection soft screen 404 are respectively wound around the outer sides of the winding reel 402 symmetrically arranged on the left and right sides;

[0031] The lateral support frame 5 is symmetrically arranged on the left and right sides of the central base 1. A lateral rotation axis 501 is arranged at the bottom of the lateral support frame 5. The lateral support frame 5 is rotatably connected to the central base 1 through the lateral rotation axis 501. A lateral guide rail 502 is arranged in the middle of the lateral support frame 5. When the lateral support frames 5 symmetrically arranged on the left and right sides are flipped to both sides to a horizontal state through the lateral rotation axis 501, the lateral guide rail 502 is aligned with the central fixed guide rail 101, and the vertical support frame 3 slides along the central fixed guide rail 101 to the lateral guide rail 502 through the translation base 301.

[0032] In this embodiment, the symmetrically arranged lateral support frames 5 on the device can be flipped to the horizontal state to both sides through the lateral rotation axis 501. At this time, the lateral guide rails 502 and the central fixed guide rails 101 are aligned with each other, and the symmetrically arranged vertical support frames 3 can be synchronously translated to both sides to slide along the central fixed guide rails 101 to the lateral guide rails 502 through the translation base 301. The left and right ends of the projection soft screen 404 are respectively wound on the outside of the winding reels 402 symmetrically arranged on the left and right sides. Therefore, when the symmetrically arranged vertical support frames 3 are synchronously translated, the winding reels 402 in the storage reels 4 arranged inside will rotate in the opposite direction synchronously to pull and release the projection soft screen 404 wound thereon, so that when the vertical support frames 3 move to the outermost side of the lateral guide rails 502 on the lateral support frames 5, the projection soft screen 404 is fully unfolded, and the central base 1 The projector 103 on the inclined projection stand 102 arranged on the upper front side can perform display work through the fully unfolded projection soft screen 404, so that the projection soft screen 404 can be automatically unfolded and stored through the symmetrically arranged unfolding and translational structure, without the need to hang the screen, which is more convenient and quick to use, and the overall structure is more compact when folded and stored, which is easy to move. Through the design of the symmetrically arranged lateral support frame 5 and the translational structure, the projection soft screen 404 can be automatically unfolded or stored as the vertical support frame 3 moves, which completely solves the problem that traditional equipment needs to unfold and hang the screen, and greatly simplifies the operation process. When not in use, the lateral support frame 5 can be flipped to a vertical state and tightly combined with the central base 1, and the volume of the entire device is greatly reduced, becoming very compact and easy to carry and store.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, preferably, a guide rack 503 is provided in the middle of the central fixed guide rail 101 and the lateral guide rail 502 of the device, a translation motor 302 is installed in the middle of the translation base 301, and a translation gear 303 is connected to the shaft end of the translation motor 302, and the translation gear 303 and the guide rack 503 are meshed with each other, and a winding motor 403 is connected in the middle of the winding reel 402, so that the winding motor 403 can drive the translation base 301 to automatically translate along the central fixed guide rail 101 and the lateral guide rail 502 through the translation gear 303 and the guide rack 503, thereby driving the vertical support frame 3 to move, so as to realize automatic unfolding and storage of the device, which is more convenient and quick to use.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, preferably, the lateral support frame 5 of the device is symmetrically provided with anti-tilt support frames 6 on both sides of the front and rear, and the outer ends of the anti-tilt support frames 6 are connected with support shafts 601, and the anti-tilt support frames 6 are rotatably connected with the lateral support frames 5 through the support shafts 601, so that when the symmetrically arranged lateral support frames 5 can be flipped to the horizontal state on both sides through the lateral shafts 501, the anti-tilt support frames 6 can be rotated outwardly through the support shafts 601 to support the device body through the anti-tilt support frames 6 on the front and rear sides, thereby improving the stability of the device when it is deployed. And safety, at the same time, the inner end of the anti-tilt support frame 6 is installed with a support screw sleeve 602, the inner side of the support screw sleeve 602 is nested and connected with a support screw 603, the top of the support screw 603 is connected with an adjusting knob 604, and the lower end of the support screw 603 is rotatably connected with a support seat 605. The anti-tilt support frame 6 is supported by the support seat 605, and the support seat 605 drives the support screw 603 to rotate by adjusting the knob 604 to adjust the height to adapt to the uneven installation ground, which is more convenient and quick to use.

When in use, the lifting support frame 202 is completely retracted into the lifting and storing groove 2, and the central base 1 is supported by the supporting foot 201. When it needs to be moved, the lifting support frame 202 lifts up the central base 1, and it can be moved by the supporting roller 203, which is more convenient and quick to use.

At this time, the central base 1 is supported by the supporting feet 201, and then the symmetrically arranged lateral support frames 5 are flipped to a horizontal state on both sides through the lateral rotating shafts 501. At the same time, the anti-tilt support frame 6 is rotated outwardly through the supporting rotating shafts 601 to deploy, so as to support the device body through the anti-tilt support frames 6 on the front and rear sides, and then the winding motor 403 is used to rotate through the translation gear 303 and the guide rack 503. The translation base 301 is driven to automatically translate along the central fixed guide rail 101 and the lateral guide rail 502, thereby driving the vertical support frame 3 to move. When the symmetrically arranged vertical support frame 3 translates synchronously, the winding reel 402 in the internally arranged storage reel 4 rotates in the opposite direction synchronously to pull and release the projection soft screen 404 wound thereon, so that when the vertical support frame 3 moves to the outermost side of the lateral guide rail 502 on the lateral support frame 5, the projection soft screen 404 is fully unfolded, and the projector 103 on the inclined projection frame 102 arranged on the upper front side of the central base 1 can project through the fully unfolded projection soft screen 404 for display.
