Detailed Implementation

[0024] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0025] This application discloses a head-mounted law enforcement recorder, such as Figure 1 As shown, it includes a wearable device 1 and a law enforcement recording device 2 installed on the side wall of the wearable device 1. An adjustment mechanism 3 is provided between the wearable device 1 and the law enforcement recording device 2.

[0026] like Figure 1 and Figure 2 As shown, the adjustment mechanism 3 includes a first adjustment rod 31 horizontally mounted on the side wall of the law enforcement recorder 2, a rotating plate 32 mounted on the end of the first adjustment rod 31 away from the law enforcement recorder 2 by countersunk bolts, a second adjustment rod 33 horizontally mounted on the side wall of the wearable device 1, and a fixed plate 34 mounted on the end of the second adjustment rod 33 away from the wearable device 1. A rotating groove 341 is provided at the end of the fixed plate 34 away from the second adjustment rod 33. The rotating plate 32 is damped and rotatably connected to the rotating groove 341, which can be understood as having a large frictional force between the rotating plate 32 and the inner wall of the rotating groove 341. A movable limiting ring 35 is sleeved on the first adjustment rod 31, and the movable limiting ring 35 is bolted to the fixed plate 34 by multiple sets of bolts and nuts. The rotating plate 32 and the rotating groove 341 facilitate the rotation of the first adjustment rod 31, thereby facilitating the adjustment of the angle of the law enforcement recorder 2. The movable limiting ring 35 prevents the rotating plate 32 from separating from the rotating groove 341, thus reducing the possibility of the law enforcement recorder 2 being damaged by a fall.

[0027] like Figure 2 andFigure 3 As shown, a cooling mechanism 4 is installed on the first adjusting rod 31. The cooling mechanism 4 includes a cooling plate 41 detachably connected to the side wall of the first adjusting rod 31, two receiving slots 411 respectively opened at both ends of one side of the cooling plate 41, and two cooling fans 42 respectively installed in the two receiving slots 411. The cooling fans 42 are designed to cool the operator's head, thereby reducing the amount of sweat entering the law enforcement recording device 2 and thus extending the service life of the law enforcement recording device 2.

[0028] like Figure 3 and Figure 4 As shown, activated carbon frames 43 are installed in two receiving slots 411, and the activated carbon frames 43 are filled with activated carbon. Each activated carbon frame 43 and the side wall of the cooling fan 42 is fixedly connected to a locking block 431. Multiple connecting cylinders 44 are installed in the receiving slots 411, and the locking blocks 431 are correspondingly engaged with the inner cavities of the connecting cylinders 44. The activated carbon frames 43 are designed to absorb sweat from the operator's head, thereby further reducing the amount of sweat entering the law enforcement recording device 2. The locking blocks 431 and connecting cylinders 44 facilitate the installation of the activated carbon frames 43 and the cooling fan 42.

[0029] like Figure 3 and Figure 4 As shown, a connecting mechanism 5 connected to the first adjusting rod 31 is installed on the cooling plate 41. The connecting mechanism 5 includes a groove 51 opened in the middle of the cooling plate 41, two connecting rods 52 that slide horizontally and are connected to both sides of the groove 51, and two connecting plates 53 that are fixed to one end of the two connecting rods 52 near the first adjusting rod 31. A connecting spring 54 is horizontally fixed to one end of each connecting plate 53 away from the first adjusting rod 31, and the end of the connecting spring 54 away from the connecting plate 53 is fixed to the inner wall of the groove 51. Inclined surfaces 531 are respectively provided on the opposite inner sides of the two connecting plates 53, and the two inclined surfaces 531 are matched with the side walls of the first adjusting rod 31. A pull rod 55 is fixed to the top of the cooling plate 41. When it is necessary to connect the cooling plate 41 to the first adjusting rod 31, first move the cooling plate 41 so that the first adjusting rod 31 is between the two connecting plates 53, and then press the cooling plate 41 down. At this time, the first adjusting rod 31 drives the connecting plate 53 to move away from the first adjusting rod 31 under the action of the inclined surface 531. The moving of the connecting plate 53 away from the first adjusting rod 31 presses against the connecting spring 54. When the cooling plate 41 is in place, the connecting plate 53 fixes the first adjusting rod 31 under the action of the connecting spring 54, so that the cooling plate 41 can be connected to the first adjusting rod 31. In summary, the connection mechanism 5 facilitates the connection of the cooling plate 41 to the first adjusting rod 31.

[0030] like Figure 3 and Figure 4As shown, the inner wall of the receiving groove 411 is provided with a mounting groove 412, and a first through hole 413 for sliding of the connecting rod 52 is provided on the side of the mounting groove 412 near the sink 51; a stabilizing mechanism 6 for improving the stability of the cooling fan 42 and the activated carbon frame 43 is installed in the mounting groove 412. The stabilizing mechanism 6 can improve the stability of the cooling fan 42 and the activated carbon frame 43.

[0031] like Figure 3 and Figure 4 As shown, the stabilizing mechanism 6 includes two second through holes 61 formed on the side of the mounting groove 412 near the receiving groove 411, two stabilizing plates 62 that are vertically slidably connected to the two second through holes 61, and a driving assembly installed in the mounting groove 412 for driving the two stabilizing plates 62 to move. The two stabilizing plates 62 abut against the side walls of the cooling fan 42 and the activated carbon frame 43, respectively. When it is necessary to improve the stability of the cooling fan 42 and the activated carbon frame 43, the two stabilizing plates 62 are first driven downward by the driving assembly. The downward movement of the two stabilizing plates 62 can press the cooling fan 42 and the activated carbon frame 43 together, thereby improving the stability of the cooling fan 42 and the activated carbon frame 43. In summary, the stabilizing mechanism 6 facilitates the improvement of the stability of the cooling fan 42 and the activated carbon frame 43.

[0032] like Figure 3 and Figure 4 As shown, the drive assembly includes a horizontally movable plate 63 that slides horizontally along the inner wall of the mounting groove 412, two push rods 64 hinged to the side of the horizontally movable plate 63 near the stabilizing plate 62, and a vertically movable plate 65 fixed to one end of the horizontally movable plate 63; the ends of the two push rods 64 away from the horizontally movable plate 63 are respectively hinged to the tops of the two stabilizing plates 62; a plurality of drive springs 66 are horizontally fixed to the side of the vertically movable plate 65 away from the horizontally movable plate 63, and the end of each drive spring 66 away from the vertically movable plate 65 is fixed to the inner wall of the mounting groove 412; the end of the connecting rod 52 away from the connecting plate 53 abuts against the side of the vertically movable plate 65 away from the horizontally movable plate 63. When the connecting plate 53 moves away from the first adjusting rod 31 under the action of the first adjusting rod 31, the connecting plate 53 drives the connecting rod 52 to move away from the first adjusting rod 31. The movement of the connecting rod 52 away from the first adjusting rod 31 drives the vertical moving plate 65 to move closer to the stabilizing plate 62. The movement of the vertical moving plate 65 to move closer to the stabilizing plate 62 drives the horizontal moving plate 63 to move closer to the stabilizing plate 62. Then, under the action of the two push rods 64, the horizontal moving plate 63 drives the two stabilizing plates 62 to move downward and press the cooling fan 42 and the activated carbon frame 43 together. In summary, the driving assembly is designed to facilitate the movement of the two stabilizing plates 62.

[0033] like Figure 4 andFigure 5 As shown, both the activated carbon frame 43 and the cooling fan 42 are fixed with clamping plates 7. The clamping plates 7 are staggered with the stabilizing plate 62. Two slots 414 are opened on the side wall of the mounting groove 412, and the two clamping plates 7 are respectively engaged in the two slots 414. A disassembly mechanism 8 is installed in the mounting groove 412 to facilitate the separation of the clamping plates 7 from the slots 414. When the cooling plate 41 is removed from the first adjusting rod 31, and it is necessary to further disassemble the activated carbon frame 43 and the cooling fan 42, the disassembly mechanism 8 facilitates the disassembly of the activated carbon frame 43 and the cooling fan 42.

[0034] like Figure 4 and Figure 5 As shown, the disassembly mechanism 8 includes a disassembly plate 81 fixed to the side of the vertical moving plate 65 near the horizontal moving plate 63, and two push balls 82 fixed to the side wall of the disassembly plate 81; the two push balls 82 can push the two locking plates 7 to move away from the locking slot 414; a drive assembly for driving the disassembly plate 81 to move towards the drive spring 66 is installed in the mounting slot 412. When it is necessary to disassemble the activated carbon frame 43 and the cooling fan 42, the disassembly plate 81 is first moved towards the drive spring 66 by the drive assembly. The movement of the disassembly plate 81 towards the drive spring 66 causes the two push balls 82 to move towards the drive spring 66. Then, the two locking plates 7 separate from the two locking slots 414 under the action of the two spherical plates. When the locking plates 7 separate from the locking slots 414, the locking block 431 separates from the connecting cylinder 44, so that the activated carbon frame 43 and the cooling fan 42 can be disassembled. In summary, the disassembly mechanism 8 facilitates the disassembly of the activated carbon frame 43 and the cooling fan 42.

[0035] like Figure 4 and Figure 5 As shown, the drive assembly includes a countersunk screw 83 that is horizontally rotatably connected to the inner wall of the mounting groove 412 via a bearing, a horizontal rod 84 that is horizontally fixed to the inner wall of the mounting groove 412, and a push plate 85 that is threaded to the side wall of the countersunk screw 83 and slidably connected to the side wall of the horizontal rod 84; the horizontal rod 84 is disposed through the push plate 85, and the push plate 85 abuts against the end of the horizontal moving plate 63 away from the vertical moving plate 65. When it is necessary to drive the disassembly plate 81 to move closer to the drive spring 66, the countersunk screw 83 is first rotated by the tool activation code. The rotation of the countersunk screw 83 drives the push plate 85 to move closer to the drive spring 66. The movement of the push plate 85 towards the drive spring 66 drives the horizontal moving plate 63 to move closer to the drive spring 66. The movement of the horizontal moving plate 63 towards the drive spring 66 drives the vertical moving plate 65 to move closer to the drive spring 66. The movement of the vertical moving plate 65 towards the drive spring 66 then drives the disassembly plate 81 to move closer to the drive spring 66. In summary, the drive assembly facilitates the movement of the disassembly plate 81 towards the drive spring 66.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
