[0002] At present, general picture frame screens are provided with an inner frame, a flexible screen and a screen tensioning device, etc. The flexible screen is arranged on the inner frame and stretched and tensioned by the tensioning device. For example, the patent number is: 202021394834.2, and the patent name is: A patent for a screen tensioning device, in which the adjusting part of the tensioning device is directly arranged on the inner frame and is driven and connected to the connecting card strip, and the flexible screen is arranged on the connecting card strip through a connecting part. During assembly, the adjusting member is rotated by an auxiliary tool to drive the connecting strip to move and then drive the connecting member to move to tighten or relax the flexible screen. As shown in the patent drawing, the adjusting part of the adjusting member is facing the inside of the inner frame. When adjusting the tensioned flexible screen, the auxiliary tool is easy to interfere with or touch the flexible screen, which is very likely to scratch the flexible screen, making it inconvenient to assemble and ensure the quality of the picture frame screen; at the same time, the adjusting member is connected through the fixed holes on the inner frame corresponding to the fixed holes on the connecting strip. When multiple tensioning devices are arranged on the same horizontal frame or vertical frame on the inner frame, it is difficult for the fixed holes on the horizontal frame or vertical frame to correspond accurately to the fixed holes on the connecting strip. Therefore, it is necessary to have higher requirements on the position accuracy of the fixed holes on the horizontal frame or vertical frame and the fixed holes on the connecting strip, thereby increasing the difficulty of workpiece processing and assembly.

For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". The subsequent description of the specification is a preferred embodiment of the present utility model, but the description is for the purpose of illustrating the general principles of the present utility model, and is not used to limit the scope of the present utility model. The scope of protection of the present utility model shall be determined as defined in the attached claims.

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings, but the present invention is not limited thereto.

[0021] Example

[0022] like Figure 1-7 As shown, a pre-installed picture frame screen comprises an inner frame assembly 1 and a flexible screen 7, wherein the inner frame assembly 1 is surrounded by frames on all sides to form a square structure; a plurality of sliders 2 are sleeved on the frames on all sides of the inner frame assembly 1, and driving rods 3 are arranged at the positions of the frames on all sides of the inner frame assembly 1, and the driving rods 3 are connected to the sliders 2 through adjusting bolts 4, and the adjusting portion 4a of the adjusting bolts 4 is arranged on the outside of the inner frame assembly 1, and the adjusting portion 4a can be adjusted to drive the driving rod 3 away from or close to the inner frame assembly 1, and the four sides of the flexible screen 7 are movably connected to the driving rods 3 arranged at the positions of the frames on all sides of the inner frame assembly 1 through connecting rods 6.

[0023] Preferably, an optical projection screen layer 8 is also provided on the flexible screen 7 .

[0024] More preferably, the frame of the inner frame assembly 1 is a square tubular structure, and the frames are detachably connected via angle codes 1a. The slider 2 is sleeved on the frame of the inner frame assembly 1 via a connecting hole 2a and can slide axially but cannot rotate radially.

[0025] like Figure 3As shown, the slider 2 is sleeved on the frame of the inner frame assembly 1 and can slide freely on the frame. During assembly, the position of the slider 2 can be adjusted in real time according to the specific position of the driving thread of the driving rod 3 to correspond thereto, so as to facilitate the corresponding assembly of the adjustment bolt 4 and the driving hole position on the driving rod 3, thereby improving the convenience of assembly and reducing the difficulty of component processing; further, as Figure 4 As shown, the slider 2 is in a 6-shaped structure, and its closed connecting hole 2a is sleeved on the frame of the inner frame assembly 1. The driving rod 3 is arranged at the notch position of the 6-shaped slider 2. The adjusting bolt 4 fixes the driving rod 3 on the slider 2 from the outer side of the frame of the inner frame assembly 1, and the adjusting part 4a of the adjusting bolt 4 can be rotated to drive the driving rod 3 away from or close to the frame of the inner frame assembly 1, thereby driving the connecting rod 6 to drive the flexible screen 7 to be in a tensioned or relaxed state. During this process, one side of the driving rod 3 abuts against the slider 2, and the other side is connected to the flexible screen 7 through the connecting rod 6 and is in a tensioned state, which can effectively maintain its stable state. At the same time, the adjusting bolt 4 adjusts the position of the driving rod 3 from the outer side of the frame of the inner frame assembly 1, so that assembly and adjustment are also more convenient, and auxiliary tools will not interfere with or touch the flexible screen 7, which can effectively ensure the assembly quality of the pre-installed picture frame screen.

[0026] More preferably, Figure 5 As shown, a snap-in groove 2b is provided at the connection position between the slider 2 and the adjustment bolt 4, and a limiting recessed groove 2c which matches the adjustment portion 4a is provided at the axial position of the snap-in groove 2b. During assembly, the adjustment bolt 4 can be pre-installed on the drive rod 3, and the adjustment bolt 4 can be quickly clamped on the slider 2 through the snap-in groove 2b, and the adjustment portion 4a can be limited by the limiting recessed groove 2c. Under the predetermined tension of the flexible screen 7, the adjustment bolt 4 can be prevented from falling out, and the adjustment portion 4a is further rotated to drive the drive rod 3 to move in the frame direction away from the inner frame assembly 1, so as to further tighten the flexible screen 7, thereby improving the convenience of assembly.

[0027] More preferably, an outer frame assembly 5 is further provided on the outer side of the inner frame assembly 1, and the outer frame buckle of the outer frame assembly 5 is provided on the frame around the inner frame assembly 1 to cover the inner frame assembly 1, the slider 2, the drive rod 3, the adjustment bolt 4 and the connecting rod 6, and a decorative corner 9 is further provided at the corner position. The method of providing the outer frame assembly 5 on the outer side of the inner frame assembly 1 and providing the decorative corner 9 at the corner can effectively cover the inner frame assembly 1, the slider 2, the drive rod 3, the adjustment bolt 4 and the connecting rod 6, improve the overall aesthetics, and at the same time effectively protect the above components, and improve the overall performance of the pre-installed picture frame screen.

[0028] More preferably, Figure 6 As shown, the inner frame assembly 1 is further provided with two or more vertical mounting rods 10, and the vertical mounting rods 10 are detachably provided with mounting ears 11 through mounting bolts 10a.

[0029] More preferably, Figure 7 As shown, the mounting lug 11 is provided with a T-shaped mounting groove, the vertical snap-in groove 11b of the T-shaped mounting groove is connected with the horizontal adjustment groove 11c, and the entrance position of the vertical snap-in groove 11b is provided with an inclined guide portion 11a. When the pre-installed picture frame screen is mounted on the mounting bolts preset on the wall through the mounting lug 11, it can be snapped into the horizontal adjustment groove 11c through the vertical snap-in groove 11b, and after both snap-in ends are snapped in, the horizontal position of the pre-installed picture frame screen can be adjusted through the horizontal adjustment groove 11c to adapt to the projection position of the laser projector for certain fine adjustment. At the same time, by providing the inclined guide portion 11a at the entrance position of the vertical snap-in groove 11b, it is convenient to achieve guidance, so as to facilitate smooth snapping into the head of the preset mounting bolt on the wall.
