[0034] Furthermore, the telescopic component includes a storage opening 18 opened on the multifunctional playback table 1, and a screw column 16 is rotatably connected to the bottom of the storage opening 18. A movable opening is opened in the telescopic plate 2, and a screw nut 17 threadedly connected to the screw column 16 is fixedly connected in the movable opening. When the screw column 16 rotates, the telescopic plate 2 connected to it through the screw nut 17 will be telescoped up and down, thereby realizing the switching between use and storage.

[0035] A folding opening 5 is provided on the side wall of the multifunctional playback table 1, and the folding opening 5 is connected to a pull plate 6 through a linkage component. Furthermore, the linkage component includes a rectangular opening provided in the folding opening 5 and connected to the storage opening 18, and a linkage rack 19 fixedly connected to the pull plate 6 is provided in the rectangular opening, and a linkage gear 20 meshing with the linkage rack 19 is fixedly connected to the outer wall of the screw column 16.

[0036] A further advantage of adopting the above method is that when the pull plate 6 is pulled outward for use, the linkage rack 19 arranged on the back of the pull plate 6 will move. When the linkage rack 19 moves, it will drive the linkage gear 20 meshing with it to rotate, thereby driving the screw column 16 to rotate, achieving the effect of automatically moving the telescopic plate 2 upward.

[0037] A width compensation plate 7 is provided on the pull plate 6 . A T-shaped expansion opening is provided on the pull plate 6 . The width compensation plate 7 is located in the T-shaped expansion opening and is fixedly connected to a limit stopper 21 .

[0038] The side wall of the width compensation plate 7 is fixedly connected with a support plate 8, and the support plate 8 is connected with an assembly rod 10 through a plurality of support rods 9, and a winding drum 11 is connected with a mounting member on the assembly rod 10, and a projection light curtain 12 is arranged on the winding drum 11;

[0039] Furthermore, the connecting mounting part includes a connecting shaft 22 which is sleeved with the winding drum 11, and an "I"-shaped connecting ring 23 is fixedly connected to the connecting shaft 22. A circular groove for installing the "I"-shaped connecting ring 23 is provided on the assembly rod 10. Rectangular hidden openings are provided on the side walls of the assembly rod 10 and multiple support rods 9. A connecting strip 24 is provided in the rectangular hidden opening, and a T-shaped connecting opening is provided on the connecting strip 24. T-shaped connecting openings are provided on both sides of the projection light curtain 12.

[0040] The setting of the rubber T-shaped connecting strip 25 enables the projection light curtain 12 to be rolled up and stored. During installation, the T-shaped connecting strips 25 on both sides of the projection light curtain 12 are inserted into the T-shaped connecting openings on the corresponding connecting strips 24 to effectively support and pull the projection light curtain 12, making it smooth and ensuring the projection quality.

[0041] Adjacent support members 9 are connected by an angle limiting assembly. Furthermore, the angle limiting assembly includes two turning rods 26 arranged between the two support members 9. Both ends of the turning rod 26 are connected to the support member 9 through a rotating shaft. A rectangular connecting port is opened on the turning rod 26, and a limiting rectangular block 27 for limiting the rotation of the support member 9 is arranged in the rectangular connecting port.

[0042] It is worth noting that a rectangular opening is opened in the middle position of the support rod member 9 for sliding connection with the limiting rectangular block 27. When it is necessary to prevent the two turning rods 26 from rotating, the limiting rectangular block 27 is inserted into the gap between the two turning rods 26 so that the limiting rectangular block 27 contacts the ends of the two turning rods 26, thereby limiting the rotation of the turning rod 26 and making it stable in different states.

[0043] Auxiliary support components are provided on multiple support rod members 9, and the auxiliary support components include a rectangular support opening opened on the support rod member 9, a horizontal rectangular groove 28 is opened in the rectangular support opening, and multiple limiting rectangular openings 29 are opened at the bottom of the horizontal rectangular groove 28, a support shaft 30 is provided in the horizontal rectangular groove 28, and the support shaft 30 is fixedly connected to a support rod 31 located in the rectangular support opening, and a triangular stopper 32 is provided on the side wall of the support rod 31.

[0044] The advantage of adopting the above method is that when the support rod members 9 are in a turning state, the support rod 31 can be moved so that the support rod 31 is tilted, and the support shaft 30 at its bottom is limited in the limiting rectangular opening 29, and its top is in conflict with the triangular stopper 32 on the other support rod 31, thereby achieving the effective limiting effect of the support rod member 9 at the turning point.

[0045] A horizontal sensor 13 is arranged on the side wall of the support rod member 9, and a projection optical device is arranged inside the projector 4. The projection optical device controls the optical distance adjustment through an electric controller. A plurality of horizontal sensors 13 are electrically connected to the electric controller. When the horizontal sensor 13 is horizontal with the ground, it will not generate a signal, and it will generate a signal only when it is in a vertical state. At this time, the horizontal sensor 13 can be numbered to distinguish where to turn, so as to determine the height and length of the projection, so as to effectively adjust the projection optical device through the electric controller to achieve the effect of self-adjusting the angle and projection distance. The projection optical device is a prior art, and its adjustment through the electric controller is also an existing adjustment method, which will not be described in detail here.

[0046] When the present invention is used for screen projection at home, the multifunctional playback table 1 is placed on the ground, and the pull plate 6 stored on the multifunctional playback table 1 is pulled outward. During the outward movement of the pull plate 6, the linkage rack 19 arranged on the back thereof drives the linkage gear 20 to rotate. During the rotation of the linkage gear 20, the lead screw column 16 connected thereto is rotated, and the lead screw nut 17 threadedly connected to the lead screw column 16 realizes the upward movement of the telescopic plate 2, so that the display screen 3 and the projector 4 are moved out from the original storage state for use;

[0047] Adjust the positions of the multiple support rods 9 connected to the support plate 8, and make reasonable self-selection to rotate at the appropriate support rod 9 according to the location of the family and the height of the projection required. After the support rod 9 turns, move out the support rod 31 set on the support rod 9 near the turning point, make one end of the support rod 31 contact with the triangular stopper 32, and move the support shaft 30 on the other end to the corresponding position of the limiting rectangular opening 29 to achieve locking, so as to strengthen the supporting force between the support rods 9;

[0048] Then, the projection light curtain 12 rolled up on the winding drum 11 is unfolded, and the connecting shaft 22 on the winding drum 11 is placed correspondingly in the circular groove arranged on the assembling rod 10, and the "I"-shaped connecting ring 23 arranged on the connecting shaft 22 effectively realizes the effective horizontal support of the two groups of support rods 9, and the projection light curtain 12 is inserted into the connecting strip 24 to realize the unfolding of the projection light curtain 12. At this time, the projection light curtain 12 does not need to be installed against the wall, and the equipment can be installed at any position for use, which has little impact on the indoor environment, and can be effectively stored when not in use, saving indoor space.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
