DETAILED DESCRIPTION

[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0033] like Figure 1 - Figure 2As shown, the present invention provides a magnetic dot matrix screen, including a mounting bracket 1 and a plurality of modules 3. The surface of the mounting bracket 1 is fixedly connected to a plurality of profiles 2. The plurality of modules 3 are all located within the mounting bracket 1. The surface of the module 3 is mounted with a plurality of back panels 4. The surface of the back panels 4 is mounted with a magnetic screen 5. The surface of the profile 2 is provided with a limiting structure 6. By providing the limiting structure 6, the entire module 3 can be easily divided into a plurality of small modules 3 for fixing, so that when a certain magnetic screen 5 is damaged, it can be quickly removed for repair or replacement, avoiding the tedious steps of removing the entire module 3 and improving the efficiency of repair. The surface of the mounting bracket 1 is provided with an adjustment structure 7. By providing the adjustment structure 7, the position of the fixing plate 74 on the mounting bracket 1 can be easily adjusted, thereby avoiding the problem of being unable to install the mounting bracket 1 on the wall due to deviation in the position of the hole in the wall, thereby facilitating the installation of the mounting bracket 1 on the wall.

[0034] The specific settings and functions of the limiting structure 6 and the adjusting structure 7 are described in detail below.

[0035] like Figure 3 and Figure 4 As shown, the limiting structure 6 includes several cylinders 61, each of which is fixedly connected to the surface of the profile 2. A screw 62 is fixedly connected to the surface of the cylinder 61, and a pressure plate 63 is mounted on the surface of the screw 62. A nut 64 is threadedly connected to the surface of the screw 62. Several clamping blocks 65 are fixedly connected to the surface of the cylinder 61. The clamping blocks 65 on the surface of the cylinder 61 will clamp the module 3, thereby positioning the module 3 and facilitating the limiting of the magnetic shield 5. The surface of the module 3 is provided with a number of grooves 66. The arcuate surface of the pressure plate 63 is fixedly connected to a number of extension plates 67. The end of the extension plate 67 away from the pressure plate 63 is fixedly connected to a limit rod 68. The size of the limit rod 68 matches the size of the groove 66. The pressure plate 63 drives the extension plate 67, which in turn drives the limit rod 68 to insert into the groove 66. When the pressure plate 63 is in contact with the surface of the module 3, the limit rod 68 is fully inserted into the groove 66. The limit rod 68 further improves the limit effect on the module 3, thereby preventing the module 3 from shaking. The surface of the nut 64 is fixedly connected to a turntable 69. The vertical cross-section of the turntable 69 is "cross" shaped. Rotating the turntable 69 drives the nut 64 to rotate. The turntable 69 facilitates the rotation of the nut 64 and avoids the need for special tools to rotate the nut 64.

[0036] like Figure 5 and Figure 6As shown, the adjustment structure 7 comprises two rectangular plates 71, each fixedly connected to either side of the mounting bracket 1. Several circular holes 72 are formed on the surfaces of the rectangular plates 71. Two frames 73 are slidably connected to the surfaces of the rectangular plates 71. A fixing plate 74 is fixedly connected to the surfaces of the frames 73. A latch 75 slidably extends through the surface of the frames 73. The dimensions of the latch 75 match those of the circular holes 72. A spring 76 is sleeved around the arcuate surface of the latch 75. The ends of the spring 76 are fixedly connected to the latch 75 and the frame 73, respectively. The latch 75 is inserted into the circular hole 72 by the contraction force of the spring 76. The spring 76 ensures the secure insertion of the latch 75 within the circular hole 72. A limiter 77 is fixedly connected to the side of the rectangular plate 71 facing away from the mounting bracket 1. During movement, the frame 73 slides along the surfaces of the rectangular plate 71 and the limiter 77. The limiter 77 limits the movement of the frame 73, preventing it from detaching from the surface of the rectangular plate 71.

[0037] Its overall working principle is that when it is necessary to limit the module 3 equipped with the magnetic screen 5 in the mounting bracket 1, first rotate the turntable 69. The rotation of the turntable 69 will drive the nut 64 to rotate. The rotation of the nut 64 will move on the surface of the screw rod 62 with the help of the thread. The movement of the nut 64 will move in the direction away from the cylinder 61. When the nut 64 is removed from the screw rod 62, the pressure plate 63 is removed from the screw rod 62, and then the module 3 is placed in the mounting bracket 1. At this time, the module 3 will be sleeved on the screw rod 62, and the module 3 will also fit on the surface of the cylinder 61. The block 65 on the surface of the cylinder 61 will clamp the module 3, thereby positioning the module 3, which is convenient for limiting the magnetic screen 5, and then the pressure plate 63 is Sleeved on the surface of the screw rod 62, the pressure plate 63 will drive the extension plate 67, and the extension plate 67 will drive the limiting rod 68 to insert into the groove 66. When the pressure plate 63 is in contact with the surface of the module 3, the limiting rod 68 will be completely inserted into the groove 66. The limiting rod 68 further improves the limiting effect on the module 3, thereby preventing the module 3 from shaking. Then the nut 64 is screwed on the surface of the screw rod 62, and the turntable 69 is rotated. The nut 64 will move toward the direction close to the pressure plate 63 with the help of the turntable 69. When the nut 64 moves to the appropriate position, it will squeeze the pressure plate 63. The pressure plate 63 will apply pressure to the module 3 with the help of the squeezing of the nut 64 until the module 3 is tightly limited in the mounting bracket 1.

[0038] When the mounting bracket 1 needs to be installed, a hole is first drilled in the wall, and then the latch 75 is pulled. The latch 75 moves within the frame 73 and gradually disengages from the circular hole 72. The movement of the latch 75 stretches the spring 76. When the latch 75 disengages from the circular hole 72, the frame 73 is moved. When the frame 73 moves, it slides along the surface of the rectangular plate 71 and the limit frame 77. The limit frame 77 limits the movement path of the frame 73, preventing the frame 73 from disengaging from the surface of the rectangular plate 71 when moving. The frame 73 drives the fixing plate 7 4 moves. When the fixing plate 74 moves to the appropriate position, the latch 75 is released. The latch 75 is inserted into the circular hole 72 with the help of the contraction force of the spring 76. The latch 75 reaches the position of the limit frame 73, thereby limiting the position of the fixing plate 74. The spring 76 improves the stability of the latch 75 inserted into the circular hole 72, thereby preventing the latch 75 from falling out of the circular hole 72 due to shaking. At this time, the fixing plate 74 coincides with the hole opened in the wall, thereby avoiding the use of bolts to fix the mounting bracket 1 to the wall, thereby facilitating the installation of the magnetic dot matrix screen on the wall.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
