DETAILED DESCRIPTION

[0031] See also Figures 1-6In an embodiment of the present invention, a retractable matrix mechanical screen includes a symmetrically arranged first frame 1 and a second frame 2, wherein the first frame 1 and the second frame 2 are symmetrically provided with openings, and the openings form a rectangular structure. The screen ratio of the opening of the rectangular structure can be 16:9, 4:3, or other ratios according to design requirements. A plurality of screen panels 3 are installed in the opening of the rectangular structure by brackets, and the screen panels 3 are electrically connected to each other through wires 31, wherein the edges of the screen panels 3 located at opposite openings on the first frame 1 and the second frame 2 are aligned with the edges of the openings of the first frame 1 and the second frame 2, and the wires 31 between the screen panels 3 on both sides of the opposite openings of the first frame 1 and the second frame 2 move through the sides of the opposite openings of the first frame 1 and the second frame 2. A rotating component 4 is connected between the first frame 1 and the second frame 2, and the first frame 1 and the second frame 2 can rotate relative to each other through the rotating component 4. The edge of the first frame 1 is movably embedded with a sealing strip 11, and the edge of the second frame 2 is embedded with a sealing groove 21 that is arranged opposite to the sealing strip 11 and movably adapted. An assembly hole 12 is embedded on the first frame 1, and an assembly protrusion 22 that is arranged opposite to and corresponds to the assembly hole 12 is fixedly connected on the second frame 2. The assembly hole 12 is transmission-connected to the sealing strip 11 through the transmission component 6. When the assembly protrusion 22 is inserted into the assembly hole 12, the assembly hole 12 drives the sealing strip 11 to move toward the sealing groove 21 through the transmission component 6.

[0032] Normally, the first frame 1 and the second frame 2 form an integral flat plate, the openings of the first frame 1 and the second frame 2 are opposite, and the screen panels 3 on the first frame 1 and the second frame 2 form a plane, the rotating component 4 is in the expanded state and connected between the first frame 1 and the second frame 2. At this time, it can be used as a whole large screen. When it is not needed for a long time, in order to avoid damage to the screen panel 3, the rotating component 4 is rotated relative to each other, so that the screen panels 3 on the first frame 1 and the second frame 2 can be rotated to a relative state. As the edges of the first frame 1 and the second frame 2 gradually fit together, the assembly protrusion 22 on the second frame 2 is gradually inserted into the assembly hole 12 on the first frame 1, and the sealing strip 11 can be pushed out through the transmission component 6 and gradually embedded in the sealing groove 21 to form a sealed protection. In this way, the entry of rain and dust can be reduced, and the maintenance and cleaning of the screen panel 3 are more convenient. Moreover, the opening and closing protection of the first frame 1 and the second frame 2 is convenient to use and can provide effective protection when not in use for a long time.

[0033] Among them, Figure 3As shown, for safety, the rotating assembly 4 is not limited to the two groups set in the figure, and multiple groups can also be set between the first frame 1 and the second frame 2. The rotating assembly 4 includes a fixed rod 42 fixedly connected to the side of the second frame 2 and a sliding rod 41 slidably embedded in the side of the first frame 1. The side of the first frame 1 is embedded with a blind hole 13. The sliding rod 41 is slidably embedded in the blind hole 13, and the sliding rod 41 and the bottom of the blind hole 13 are connected by a spring. A rotating rod 43 is rotatably connected between the end of the sliding rod 41 away from the first frame 1 and the end of the fixed rod 42 away from the second frame 2. The length of the rotating rod 43 is the same as that of the first frame 1 and the second frame 2. After the sliding rod 43 is overlapped, the sliding rod 43 The spacing between the sliding rod 41 and the fixed rod 42 is the same. The sliding rod 41 and the fixed rod 42 are both cylindrical structures. The sizes of the sliding rod 41, the fixed rod 42 and the blind hole 13 match. When the first frame 1 and the second frame 2 are unfolded, the fixed rod 42 and the sliding rod 41 can be received in the blind hole 13. The width of the rotating rod 43 is not greater than the diameter of the sliding rod 41 and the fixed rod 42. When the sliding rod 41, the fixed rod 42 and the rotating rod 43 are unfolded in a straight line, they can all be received in the blind hole 13. The spring at the end of the sliding rod 41 acts to shrink the sliding rod 41 into the blind hole 13. This arrangement facilitates the opening and closing of the first frame 1 and the second frame 2, and compared with the traditional rotating hinge, this structural arrangement can avoid collision of the edge of the screen panel 3 during rotation, reducing the risk of damage. When the first frame 1 and the second frame 2 are deployed, the sliding rod 41, the fixed rod 42, and the rotating rod 43 can all be retracted into the blind hole 13. The cooperation between the fixed rod 42 and the blind hole 13 can facilitate the stability of the first frame 1 and the second frame 2 when deployed. When not in use for a long time, the second frame 2 can be moved away from the first frame 1. At this time, the fixed rod 42 and the rotating rod 43 can be pulled out of the blind hole 13, and the end of the sliding rod 41 is also pulled out of the blind hole 13. At this time, the first frame 1 and the second frame 2 can rotate relative to each other through the cooperation of the sliding rod 41, the fixed rod 42, and the rotating rod 43, thereby achieving the superposition of the first frame 1 and the second frame 2. After alignment is completed, the spring acts to tighten the sliding rod 41 into the blind hole 13, which is also convenient for cooperating to maintain the stability of the first frame 1 and the second frame 2 when superimposed. When the first frame 1 and the second frame 2 rotate relative to each other, the wire 31 can extend from the side of the first frame 1 and the second frame 2, and can be retracted into the first frame 1 and the second frame 2 when the first frame 1 and the second frame 2 form a plane.

[0034] In order to prevent the wire 31 from being exposed when the first frame 1 and the second frame 2 are relatively overlapped, as shown in FIG. Figure 4As shown, a receiving groove 23 is embedded in the side of the second frame 2, and a reel (not shown in the figure) is rotatably connected in the receiving groove 23. The reel is connected to the inner wall of the receiving groove 23 by a torsion spring. A curtain 5 is wound on the reel, and the end of the curtain 5 away from the reel extends from the receiving groove 23 and is fixedly connected to the side of the first frame 1. When the first frame 1 and the second frame 2 form a plane, the reel reels the curtain 5, and when the first frame 1 and the second frame 2 rotate relative to each other and overlap, the curtain 5 on the reel is pulled out and tightly fits on the side of the first frame 1 and the second frame 2. The curtain 5 covers the wires 31 on the side of the first frame 1 and the second frame 2 and the surface of the connection. Preferably, a hook, Velcro or other structure that can movably close the edge of the curtain 5 can be added to protect the wires 31 and the edge of the screen panel 3 to prevent them from being exposed to rain and dust.

[0035] like Figure 5 As shown, the assembly hole 12 is a threaded cylindrical structure, and the assembly hole 12 is convenient for disassembly and maintenance. Guide rails 1201 are symmetrically embedded on both sides of the inner wall of the assembly hole 12, and a sliding gasket 1202 is provided in the assembly hole 12 for sliding cooperation. The side of the sliding gasket 1202 is provided with a protrusion that slides and adapts to the guide rail 1201, and one end of the transmission component 6 is movably engaged with the inner side of the sliding gasket 1202. The diameter of the assembly protrusion 22 is smaller than the opening diameter of the assembly hole 12. In this way, after the second frame 2 rotates relatively, the assembly protrusion 22 is also conveniently inserted into the assembly hole 12. After the assembly protrusion 22 contacts the sliding gasket 1202, the sliding gasket 1202 can be pressed into the assembly hole 12, so that the sealing strip 11 can be driven by the transmission component 6 to move toward the sealing groove 21, thereby forming a seal, avoiding the problem of poor sealing effect caused by squeezing of the conventional fixed sealing strip 11 and the sealing groove 21 during rotation.

[0036] like Figure 6 As shown, the sealing strip 11 includes a "U"-shaped frame that is slidably embedded in the edge of the surface of the first frame 1 and a rubber pad embedded in the surface of the "U"-shaped frame. The sealing strip 11 is embedded in the side of the first frame 1 and is fixedly connected with multiple groups of guide rods 1101. The guide rods 1101 are slidably connected in the first frame 1. A spring is connected between the guide rods 1101 and the first frame 1, and the spring acts to retract the guide rods 1101 into the first frame 1.

[0037] like Figures 6-10As shown, the transmission assembly 6 includes a rotating plate 61, which is rotatably connected to the first frame 1 through a support plate 62. A first strip-shaped hole 64 is provided at one end of the rotating plate 61, and the other end of the rotating plate 61 slides against the side of the sealing strip 11. An elastic member is provided in a sliding fit in the first strip-shaped hole 64. The elastic member is connected to the first frame 1, and the end thereof slides against the surface of the sliding gasket 1202. When the assembly protrusion 22 is inserted into the assembly hole 12, the sliding gasket 1202 presses against the surface of the elastic member, and the elastic member drives the end of the rotating plate 61 to move downward, and the other end of the rotating plate 61 moves upward like a seesaw, thereby driving the sealing strip 11 to move away from the first frame 1, thereby achieving automatic sealing. Among them, the elastic part includes an elastic rod 67 elastically connected to the first frame 1, the elastic rod 67 slides through the first strip hole 64, and the end of the elastic rod 67 slides and abuts against the surface of the sliding gasket 1202. The elastic rod 67 is fixedly connected to the periphery of the elastic rod 67 with an annular gasket 68, and the annular gasket 68 is movably fitted on the surface of the rotating plate 61. In this way, when the sliding gasket 1202 pushes the elastic rod 67 to move into the first frame 1, the annular gasket 68 can be used to press down the end of the rotating plate 61, thereby pushing the sealing strip 11 away from the first frame 1.

[0038] The cam 63 is engaged with the cam 64 and the cam 66, and the cam 66 is engaged with the cam 64 so that the cam 64 is engaged with the cam 66. The support plate 63 is provided with a second strip-shaped hole 65 through which the guide rod 1101 slides. When the support plate 63 pushes the sealing strip 11 to move, the support plate 63 is in contact with the surface of the sealing strip 11, but its position will shift relative to the surface. Therefore, the second strip-shaped hole 65 facilitates the passage of the guide rod 1101 while preventing it from getting stuck.
