Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 、 Figure 2 and Figure 4The cam 6 of the embodiment of the present invention is a kind of head-mounted monitoring device, comprises a front plate 1, and both ends of the front plate 1 are fixedly connected with a strap 3, and the rear ends of the two straps 3 are fixedly connected with a connecting block 4, and a card slot 6 is provided on the right side of the left connecting block 4, and a card buckle 5 is fixedly connected to the left side of the right connecting block 4, and then the card buckle 5 is inserted into the corresponding card slot 6 for fixing. The original plate 13 and the left and right sides of the front end of the front plate 1 are fixedly connected to the fixed plate 14, and the fixed plate 14 provides support. The adjacent sides of the two fixed plates 14 are provided with a U-shaped plate 16, and the two sides of the U-shaped plate 16 are provided with a rotating assembly. The front side of the U-shaped plate 16 is slidably connected to the camera 20. The front side of the front plate 1 is provided with a mounting mechanism 2, and the mounting mechanism 2 is used to install the camera 20. The rotating assembly includes two rotating shafts 15. The two rotating shafts 15 are respectively rotatably connected to the adjacent sides of the fixed plate 14 to provide a rotating mechanism for the U-shaped plate 16. One end of the two rotating shafts 15 is respectively fixedly connected to the two sides of the U-shaped plate 16. The outer wall of the right rotating shaft 15 is fixedly connected to the driven gear 17. The right side of the right fixed plate 14 is rotatably connected to the rotating rod 18. The rotating rod 18 can drive the driving gear 19 to rotate. The left end of the rotating rod 18 passes through the fixed plate 14 and is fixedly connected to the driving gear 19. The driving gear 19 is meshed with the driven gear 17, and the driving gear 19 can drive the driven gear 17 to rotate.

[0033] Specifically, two straps 3 are wrapped around the head so as to fit on both sides of the head, and then the buckle 5 is inserted into the corresponding slot 6 to ensure that the buckle 5 fits the slot 6. After the buckle 5 is successfully inserted into the slot 6, the position of the top strap 8 needs to be adjusted so that it can move smoothly in the hollow block 7. The top strap 8 is carefully adjusted until a suitable position is found so that the wearer feels comfortable and stable. Once the top strap 8 is adjusted into place, the spring 11 will automatically pop up and push the limiter 12 out so that it is accurately stuck in the corresponding limit hole 9. The entire device can be worn stably on the head and will not slip or shift easily. If the angle of the camera 20 needs to be adjusted, the rotating rod 18 can be rotated. Rotating the rotating rod 18 will drive the active gear 19 to rotate together, and then the right rotating shaft 15 will rotate accordingly, so that the angle of the camera 20 can be easily adjusted.

[0034] Reference Figure 2 and Figure 3The mounting mechanism 2 includes two limit blocks 201, which are fixedly connected to the two ends of the rear side of the camera 20. The two limit blocks 201 are respectively provided with limit slots 202 at both ends of the inner front side of the U-shaped plate 16. The two limit blocks 201 slide inside the corresponding limit slots 202. The top of the U-shaped plate 16 is fixedly connected to the second rotating shaft 203. The top of the second rotating shaft 203 is rotatably connected to the cover plate 204. The top front end of the cover plate 204 is rotatably connected to the limit bolts 205 at both ends.

[0035] Specifically, first, the limit block 201 is accurately aligned with the position of the limit slot 202, and then the camera 20 is gently pushed to ensure that the limit block 201 can slide smoothly inside the limit slot 202, and the cover plate 204 is rotated, rotated and placed above the camera 20. At this time, the limit bolt 205 is rotated, rotated and pushed into the U-shaped plate 16. The limit bolt 205 will be fixed in the U-shaped plate 16, thereby ensuring that the cover plate 204 is fixed above the camera 20. This installation and disassembly method is very simple and improves the work efficiency of the staff.

[0036] Reference Figure 2 and Figure 3 , the left and right sides of the two limit slots 202 are provided with slide grooves 21, and both sides of the two limit blocks 201 are fixedly connected with sliders 22. Multiple sliders 22 slide in the corresponding slide grooves 21, which can make the limit blocks 201 move more smoothly and stably in the limit slots 202. Grooves 23 are provided at both ends of the rear side of the front plate 1, and springs 24 are fixedly connected to the inside of the two grooves 23.

[0037] Specifically, the slide groove 21 and the slider 22 can allow the limit block 201 to move more smoothly and stably in the limit groove 202. The spring 24 and the pad 25 can protect the user's head and reduce the impact caused by the shaking when the device shakes. The soft pad 27 can prevent the front of the device from sliding and play a buffering role.

[0038] Reference Figure 1 and Figure 5 The top of the front plate 1 is fixedly connected with an arc-shaped plate 26. The top of the arc-shaped plate 26 is fixedly connected to the front side of the connecting original plate 13. The arc-shaped plate 26 plays a fixing role for the connecting original plate 13. The front end of the limiter 12 passes through the corresponding limit hole 9 in sequence. The size of the limiter 12 is consistent with that of the limit hole 9, which makes it more stable when fixed.

[0039] Specifically, the arc-shaped plate 26 plays a fixing role on the connecting original plate 13 so that the top belt 8 will not fall off during use. The size of the limiter 12 is consistent with that of the limiting hole 9, making it more stable when fixed and limited.

[0040] Working principle: When using a head-mounted monitoring device, first wrap the two straps 3 around the head, and snap the buckle 5 on the right connecting block 4 into the slot 6 of the left connecting block 4 to achieve preliminary fixation. The hollow block 7 in the middle of the two straps 3 is used to adjust the length of the top strap 8. The top strap 8 slides in the hollow block 7. When adjusted to the appropriate position, the spring 11 in the circular groove 10 pops out the limiter 12, causing it to snap into the corresponding limit hole 9, thereby fixing the length of the top strap 8 and ensuring that the entire device is firmly worn on the head. During the monitoring process, the camera 20 at the front end of the front plate 1 is responsible for collecting image information. When the angle of the camera 20 needs to be adjusted, turn the rotating rod 18, and the rotating rod 18 drives the active gear 19 to rotate. The active gear 19 engages with the driven gear 17, thereby rotating the right shaft 15, and then drives the U-shaped plate 16 to rotate, achieving adjustment of the angle of the camera 20.

[0041] When installing the camera 20, align the limit blocks 201 at both ends of the rear side of the camera 20 with the limit grooves 202 at both ends of the front side inside the U-shaped plate 16, and then push the camera 20 so that the limit blocks 201 slide inside the limit grooves 202 to achieve the initial positioning of the camera 20. Then, rotate the cover plate 204 around the second rotation axis 203 so that it covers the top of the camera 20, and then rotate the limit bolt 205 so that the limit bolt 205 is rotated into the U-shaped plate 16, thereby fixing the cover plate 204 and then firmly installing the camera 20 on the U-shaped plate 16.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
