[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figures 1 to 5 A law enforcement recorder with a noise filtering function comprises a law enforcement recorder body, a connecting plate 2 is arranged at the rear of the law enforcement recorder body, a shoulder clip is arranged on the connecting plate 2, the shoulder clip comprises a mounting frame 3, a torsion spring 4, a bottom plate 5 and a clamping plate 6, the bottom plate 5 is arranged on the connecting plate 2, the mounting frame 3 is arranged on the bottom plate 5, the torsion spring 4 is arranged in the mounting frame 3, the clamping plate 6 is connected in the mounting frame 3 through a rotating shaft, the other end of the clamping plate 6 is connected to one side of the torsion spring 4, a groove 7 is arranged on one side of the clamping plate 6, a connecting belt 8 is arranged in the groove 7, a Velcro mother surface 9 is arranged on one side of the connecting belt 8, and a Velcro sub-surface 10 is arranged on the upper side of the clamping plate 6.

[0024] When the present device is in use, the clamping plate 6 can be pressed to wear the law enforcement recorder body where it can be clamped and fixed, such as a pocket. If the law enforcement recorder body needs to be worn in other places, such as arms, etc., it is only necessary to rotate the bottom plate 5 90 degrees, wrap the connecting belt 8 around the arm, and fix the law enforcement recorder body by fitting the Velcro sub-surface 10 to the Velcro mother surface 9. In this way, the law enforcement recorder body is fixed on the arm. Compared with the prior art, the present device has a connecting belt 8, and when in use, the connecting belt 8 can be used to fix the law enforcement recorder body in different positions to adapt to different law enforcement scenarios. This solves the problem that the wearing method of the law enforcement recorder in the prior art is relatively single and some wearing methods are also relatively inconvenient in special law enforcement processes.

[0025] Furthermore, the law enforcement recorder body includes a shell 1, a video acquisition module 11, an audio acquisition module 12 and a display screen 13. The display screen 13 is arranged on one side of the shell 1, the video acquisition module 11 is arranged above the display screen 13, and the audio acquisition module 12 is arranged above the shell 1. The video acquisition module 11 is a camera that can shoot video, and the audio acquisition module 12 is a microphone that can record the scene. A control processor is also arranged in the shell 1. The signal output ends of the video acquisition module 11 and the audio acquisition module 12 are connected to the signal input end of the control processor, and the signal output end of the control processor is connected to a memory, which can store the collected content as law enforcement evidence.

[0026] Furthermore, limiting mechanisms are provided on both sides of the clamping plate 6, and the limiting mechanisms include two second springs 14, two slide grooves 15 and two limiting blocks 16. The two slide grooves 15 are provided on both sides of the clamping plate 6, and the two second springs 14 are provided in the corresponding slide grooves 15. The two limiting blocks 16 are provided on the other side of the corresponding second springs 14. The limiting blocks 16 are L-shaped, and limiting grooves 17 are provided on the two limiting blocks 16. The connecting belt 8 passes through the two limiting blocks 16, and the limiting blocks 16 can be connected by the provided springs. The end of the connecting belt 8 is T-shaped, and the folded connecting belt 8 can be fixed in the two limiting grooves 17 through the limiting blocks 16 (the T-shaped end of the connecting belt 8 cannot pass through the limiting groove 17 and needs to be taken out first, and the rear part of the connecting belt 8 can pass through). At this time, it is convenient to use the clamping plate 6 for clamping, and the limiting groove 17 can continuously pull out the rear part of the connecting belt 8 after the T-shaped end of the connecting belt 8 is pulled out, so as to facilitate the use of the connecting belt 8 for clamping.

[0027] Furthermore, the width of the groove 7 is greater than the thickness of the connecting belt 8 , and the connecting belt 8 is folded and stored in the groove 7 , so that the connecting belt 8 can be stored in the groove 7 .

[0028] Furthermore, a first fixing mechanism is provided on the clamping plate 6, and the first fixing mechanism includes two first threaded holes 18. The two first threaded holes 18 are provided on one side of the clamping plate 6, and the first threaded holes 18 extend into the groove 7. A bolt 19 is provided on one side of the first threaded hole 18, and the bolt 19 is adapted to the first threaded hole 18. The bolt 19 is a butterfly bolt 19. When the folded connecting belt 8 is in the groove 7, the bolt 19 can be rotated to resist the connecting belt 8 and restrict it in the groove 7. Since the bolt 19 is a butterfly bolt 19, it is convenient to manually twist it.

[0029] Furthermore, the base plate 5 is rotatably connected to the connecting plate 2 via a rotating shaft, and one end of the base plate 5 is detachably connected to the connecting plate via a second fixing mechanism, and the second fixing mechanism includes a fixing hole 22, two second threaded holes 20 and a screw 21, and the two second threaded holes 20 are both arranged on the connecting plate 2, and the fixing hole 22 is arranged on the base plate 5, and the positions of the two second threaded holes 20 correspond to the fixing holes 22, and the screw 21 passes through the fixing hole 22 and is threadedly connected to the second threaded hole 20. The connection between the screw 21 and the second threaded hole 20 can prevent the base plate 5 from rotating via the rotating shaft, and when the connecting belt 8 needs to be pulled out, the direction of the connecting belt 8 can be changed by removing the screw 21 from the second threaded hole 20 and rotating the base plate 5, so that the connecting belt 8 is convenient to use.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that:

[0032] In this embodiment, a waterproof sound-permeable membrane 23 is provided on one side of the audio acquisition module 12, a first sound-gathering layer 24 is provided on the inner side of the waterproof sound-permeable membrane 23, a sound receiving head 25 is provided on the inner side of the audio acquisition module 12 close to the first sound-gathering layer 24, and a second sound-gathering layer 26 is provided on the outer side of the sound receiving head 25, so as to effectively reduce the interference of external noise on the sound signal recorded by the audio acquisition module 12, and ensure that the user's voice is confined in the sound-gathering layer and does not leak out, thereby improving the effect of filtering noise by the audio acquisition module 12 and ensuring the effect of using the audio acquisition module 12. At the same time, a denoising module is provided inside the shell 1, which can further improve the effect of removing noise and effectively reduce the impact of environmental noise on the audience.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
