Description

Technical Field

[0001] This utility model relates to the field of picture frame screen technology, and in particular to the structure of an aluminum alloy picture frame screen. Background Technology

[0002] Projection screens are used in cinemas, offices, home theaters, large conferences, and other settings to display images and video files. They come in many sizes and specifications, and the choice of projection screen varies depending on the space. For example, for a large number of viewers or horizontal viewing, a wide-viewing-angle, low-gain screen is suitable, while for viewing in narrow spaces, a narrow-viewing-angle, high-gain screen is preferable. Choosing a screen with appropriate gain helps improve screen contrast, increasing image grayscale and color vibrancy, thus enhancing image viewing quality. Framed projection screens are a widely recommended design. Their simple structure consists of an aluminum alloy frame resembling a picture frame, with the screen enclosed on the outside. However, framed projection screens currently on the market still have the following problems in practical use:

[0003] 1. There are many parts, and the assembly process is complicated. Some parts cannot be reused after assembly.

[0004] 2. In order to reinforce the frame, multiple support rods will be installed on the inside of the frame. The existing support rods are fixed by friction, which poses a risk of tilting or falling. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a structure for an aluminum alloy picture frame screen. This structure offers greater overall stability during use and is easier to assemble and disassemble. Furthermore, the support rods are connected using screw-based locking mechanisms, resulting in higher overall strength.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A structure for an aluminum alloy picture frame screen includes a mounting frame, a screen body, and a U-shaped frame. The mounting frame consists of two horizontal bars and two vertical bars. An L-shaped connecting plate is provided on the rear side of the contact point between each horizontal bar and the corresponding vertical bar. Each L-shaped connecting plate is fixedly connected to the corresponding horizontal bar and vertical bar by a first connecting screw. A reinforcing mechanism includes multiple support rods disposed between the two horizontal bars. Each support rod has a horizontal connecting plate fixedly connected to its upper and lower ends. Each horizontal connecting plate is connected to the corresponding horizontal bar by multiple second connecting screws.

[0008] Preferably, both sides of each horizontal bar and both sides of each vertical bar are inclined surfaces with an angle of 45°.

[0009] Preferably, the front side of the loop frame is symmetrically fixed with two pull rings.

[0010] Preferably, the herringbone frame is magnetic.

[0011] Preferably, the front sides of the two horizontal bars are provided with horizontal grooves, and the front sides of the two vertical bars are provided with vertical grooves. The two horizontal grooves and the two vertical grooves together form a spiral groove, which cooperates with the spiral frame.

[0012] Preferably, both horizontal bars and both vertical bars are made of an iron-aluminum alloy.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] The system is equipped with support rods, which are connected via a second connecting screw. This method provides reinforcement. The screen is connected using a magnetic clasp, which confines the edge of the screen body within the clasp. This makes installation and disassembly simple and convenient. Furthermore, the clasp further reinforces the system, enhancing overall stability. The system can also be disassembled into multiple parts, allowing for individual replacement of any damaged components, thus increasing its adaptability. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Reference Figures 1-3 A structure of an aluminum alloy picture frame screen includes a mounting frame, a screen body 3 and a U-shaped frame 4. Two pull rings 5 ​​are symmetrically fixed to the front side of the U-shaped frame 4, and the U-shaped frame 4 is magnetic.

[0022] The mounting frame consists of two horizontal bars 1 and two vertical bars 2. Each horizontal bar 1 and the corresponding vertical bar 2 has an L-shaped connecting plate 7 at the rear of the contact point. Each L-shaped connecting plate 7 is fixedly connected to the corresponding horizontal bar 1 and vertical bar 2 by a first connecting screw 8. Both sides of each horizontal bar 1 and both sides of each vertical bar 2 are inclined surfaces with an angle of 45°.

[0023] It also includes a reinforcement mechanism, which includes multiple support rods 6 arranged between two crossbars 1. Each support rod 6 has a horizontal connecting plate 9 fixedly connected to its upper and lower ends. Each horizontal connecting plate 9 is connected to the corresponding crossbar 1 by multiple second connecting screws 10.

[0024] The front sides of the two horizontal bars 1 are provided with horizontal grooves, and the front sides of the two vertical bars 2 are provided with vertical grooves. The two horizontal grooves and the two vertical grooves together form a spiral groove 11, which cooperates with the spiral frame 4. The two horizontal bars 1 and the two vertical bars 2 are all made of iron-aluminum alloy.

[0025] In this utility model, during specific operation, the connecting frame is first assembled by placing the two horizontal bars 1 and the two vertical bars 2 with their front sides facing down on the table. Then, by using multiple L-shaped connecting plates 7 in conjunction with the first connecting screws 8, the connecting frame can be assembled. Then, by using multiple second connecting screws 10, multiple support rods 6 are installed between the two horizontal bars 1 to improve the stability of the actual connecting frame.

[0026] Then, place the connecting frame with the back side facing down on the table, and lay the screen body 3 flat on top of the connecting frame. Cover the four sides of the screen body 3 with the herringbone groove 11, and then insert the herringbone frame 4 into the herringbone groove 11, limiting the edge of the screen body 3 in the herringbone groove 11. The herringbone frame 4 is tightly limited in the herringbone groove 11 by magnetic force, completing the overall installation. The use of the herringbone frame 4 can also further strengthen the overall stability. Subsequent disassembly and replacement of the screen is relatively convenient because of the magnetic connection.
