[0031] The specific settings and functions of the installation structure 3 and the protective structure 4 are described in detail below.

[0032] Reference Figure 1-Figure 4 As shown, in this embodiment: the mounting structure 3 includes a mounting frame 31 located below the decoding module 1, two screws 33 are inserted into the lower surface of the mounting frame 31, and two shielding frames 35 are slidably connected to the upper side of the mounting frame 31. The shielding frame 35 moves to the upper side of the decoding module 1, and at this time, the limiting shielding work of the decoding module 1 inside the mounting frame 31 can be realized, thereby realizing the rapid installation of the decoding module 1. Two positioning pins 34 are fixedly connected to the surface of the mounting frame 31, and two positioning holes 36 are provided on the lower surface of the decoding module 1, and the size of the positioning holes 36 is adapted to the size of the positioning pins 34. In the process of the decoding module 1 sliding down, the positioning holes 36 on the decoding module 1 are placed on the surface of the positioning pins 34, so as to realize the positioning work of the decoding module 1 and avoid the phenomenon that the decoding module 1 slides inside the mounting frame 31 during the use in the later stage.

[0033] A first spring 38 is fixedly connected between the shielding frame 35 and the mounting frame 31. Two auxiliary blocks 37 are fixedly connected to the upper surface of the shielding frame 35. The upper side of the auxiliary blocks 37 is an inclined structure. The staff can use the screws 33 to fix the mounting frame 31 on the equipment. When it is necessary to install the decoding module 1 and the mounting frame 31, the staff can press down the decoding module 1, and the decoding module 1 will slide along the inclined surface of the auxiliary blocks 37 to the inner side of the mounting frame 31. When the decoding module 1 is completely moved to the inner side of the mounting frame 31, the shielding frame 35 will be driven by the pulling force of the first spring 38 to move the shielding frame 35 to the upper side of the decoding module 1. A connecting block 39 is fixedly connected to the lower surface of the shielding frame 35. The inner part of the connecting block 39 is rotatably connected to the support frame 32. The support frame 32 is an "L"-shaped structure. When it is necessary to disassemble the decoding module 1, first pull the shielding frame 35 to the side away from the decoding module 1. When the shielding frame 35 is moved out from above the decoding module 1, rotate the support frame 32 inside the connecting block 39 to a position where it can be supported on the surface of the mounting frame 31, and release the shielding frame 35. At this time, the support frame 32 can temporarily support and fix the position of the shielding frame 35 after pulling out.

[0034] Reference Figure 1 and Figure 5 As shown, specifically, the protective structure 4 includes a fixed rod 41 fixedly connected to the surface of the decoding module 1, and the other end of the fixed rod 41 is fixedly connected to a groove block 43, and the inner part of the groove block 43 is slidably connected to a limit plate 42. The limit plate 42 inside the sliding groove block 43 is used to put the wire on the plug in the position between the groove block 43 and the limit plate 42, and the plug is inserted into the inner wall of the socket 2 on the decoding module 1, so as to realize the surrounding and limiting work of the wire. A plurality of arc-shaped thorns 44 are fixedly connected to the inner side of the limit plate 42. When the wire is subjected to external force, the wire will be inserted upside down inside the wire, thereby preventing the wire from driving the plug to slide out from the inner side of the socket 2.

[0035] A second spring 46 is fixedly connected between the limit plate 42 and the groove block 43. The limit plate 42 is inserted into the inner side of the reserved hole 45 by the pulling force of the second spring 46 on the groove block 43. The surface of the groove block 43 is provided with a reserved hole 45, and the size of the reserved hole 45 is adapted to the size of the limit plate 42. The limit plate 42 is inserted into the inner wall of the reserved hole 45, so as to improve the tightness of surrounding the wire.

[0036] Working principle: This AHD decoding box is used in the car. The internal circuit board is integrated with a control circuit. It is a device for video surveillance systems and is mainly used to decode AHD signals. AHD is a high-definition analog video transmission technology that can provide high-definition video image quality. The AHD box is used to decode the video output signal of the vehicle system into a high-definition video signal and transmit it to the display screen for display. The staff can use screws 33 to fix the mounting bracket 31 on the equipment. When it is necessary to install the decoding module 1 and the mounting bracket 31, the staff can press down the decoding module 1, and the decoding module 1 will slide along the inclined surface of the auxiliary block 37 to the inner side of the mounting bracket 31. During the sliding of the decoding module 1, the positioning hole 36 on the decoding module 1 is placed on the surface of the positioning pin 34, so as to realize the positioning of the decoding module 1 and avoid the phenomenon that the decoding module 1 slides on the inner side of the mounting bracket 31 during the later use. When the decoding module 1 is completely moved to the inner side of the mounting bracket 31, the shielding bracket 35 will be affected. The pulling force of the first spring 38 drives the shielding frame 35 to move to the upper side of the decoding module 1. At this time, the limiting shielding work of the decoding module 1 inside the mounting frame 31 can be realized, thereby realizing the rapid installation of the decoding module 1. When the decoding module 1 needs to be disassembled, the shielding frame 35 is first pulled to the side away from the decoding module 1. When the shielding frame 35 is moved out from the top of the decoding module 1, the support frame 32 inside the connecting block 39 is rotated, and the support frame 32 is rotated to a position where it can be supported on the surface of the mounting frame 31, and the shielding frame 35 is loosened. At this time, the support frame 32 can realize the temporary support and fixing work of the position of the shielding frame 35 after pulling. By setting the mounting structure 3, the flexible disassembly and assembly of the decoding module 1 inside the mounting frame 31 is facilitated, and no external tools are required during the disassembly and assembly process, thereby avoiding the use of screws in the traditional installation process, and the phenomenon that the screws are easily lost, thereby improving the installation and use efficiency of the decoding module 1 to a certain extent, and facilitating the regular disassembly and assembly and maintenance of the decoding module 1.

[0037] The limiting plate 42 inside the sliding groove block 43 is used to put the wire on the plug in the position between the groove block 43 and the limiting plate 42, and the plug is inserted into the inner wall of the socket 2 on the decoding module 1. At this time, the limiting plate 42 is released, and the limiting plate 42 is inserted into the inner side of the reserved hole 45 by the pulling force of the second spring 46 on the groove block 43, so as to realize the surrounding and limiting work of the wire. When the wire is subjected to external force, the wire will be inserted upside down inside the wire, thereby avoiding the situation that the wire drives the plug to slide out from the inner side of the socket 2, and improving the stability of the decoding module 1 during use. The limiting plate 42 is inserted into the inner wall of the reserved hole 45, and the tightness of the surrounding of the wire is improved. By setting the protective structure 4, it is convenient to prevent the wire on the plug inserted into the socket 2 from falling off, and to a certain extent, the stability of the decoding module 1 during use.
