[0027] See also Figure 1-4 The utility model provides a technical solution: an elevator car monitoring device that is easy to adjust, comprising:

[0028] A mounting frame 2, wherein the mounting frame 2 is internally rotatably connected to a rotating seat 3, and a monitoring camera 1 is installed at the bottom of the rotating seat 3;

[0029] A monitoring installation structure, the monitoring installation structure is located on the rotating seat 3;

[0030] The monitoring installation structure includes a plug-in column 8 and two limit sliders 9. The plug-in column 8 is fixedly connected to the top of the monitoring camera 1. The two limit sliders 9 are fixedly connected to the outer surface of the plug-in column 8. A plug-in groove 12 is provided at the bottom of the rotating seat 3. Two limit slides 10 are provided on the inner wall of the plug-in groove 12. The two limit slides 10 are both "L"-shaped. The plug-in column 8 is slidably connected to the inside of the plug-in groove 12, and the two limit sliders 9 are slidably connected to the corresponding limit slides 10.

[0031] The monitoring installation structure also includes two installation rods 4, two springs 14, two limit plates 13 and two trapezoidal blocks 11. Two sliding grooves 15 are opened inside the rotating seat 3. The two limit plates 13 are slidably connected in the corresponding sliding grooves 15. The two installation rods 4 are fixedly connected to the corresponding limit plates 13. The two springs 14 are sleeved on the outside of the corresponding installation rods 4. The side of the two installation rods 4 away from the corresponding limit plates 13 slides through the side of the corresponding sliding groove 15. The two trapezoidal blocks 11 are fixedly connected to the corresponding limit plates 13. The ends of the two trapezoidal blocks 11 away from the corresponding limit plates 13 extend into the plug-in slot 12.

[0032] One end of the two springs 14 is fixedly connected to the corresponding limiting plate 13 , and one end of the two springs 14 away from the corresponding limiting plate 13 is fixedly connected to the inner wall of the corresponding sliding groove 15 .

[0033] The inner wall of the mounting frame 2 is fixedly connected with a driving motor 6, the output end of the driving motor 6 is fixedly connected with a first bevel gear 5, the top of the rotating seat 3 is fixedly connected with a second bevel gear 7, the first bevel gear 5 is meshed with the second bevel gear 7, and the top of the mounting frame 2 is provided with four bolt mounting grooves 16 for facilitating bolt installation.

[0034] Furthermore, when using the device, the driving motor 6 is started by connecting an external power supply, and the driving motor 6 drives the first bevel gear 5 to rotate. Under the meshing connection between the first bevel gear 5 and the second bevel gear 7, the first bevel gear 5 rotates to drive the second bevel gear 7 to rotate the rotating seat 3 in the mounting bracket 2, thereby facilitating the adjustment of the angle of the monitoring camera 1. When installing the monitoring camera 1, the staff will plug the limiting slide grooves 10 corresponding to the two limiting sliders 9 on the top of the monitoring camera 1 into correspondence, so that when the two limiting sliders 9 slide in the corresponding limiting slide grooves 10, they will contact the corresponding trapezoidal card blocks 11. When the plug-in column 8 is slidably connected in the plug-in groove 12, the two limiting sliders 9 will compress the corresponding trapezoidal card blocks 11 and retract them into the corresponding sliding grooves 15. The movement of each trapezoidal block 11 drives the corresponding limit plate 13 to move under the guidance of the corresponding sliding groove 15. The movement of the two limit plates 13 drives the corresponding installation rods 4 to move and compress the corresponding springs 14. Then, the monitoring camera 1 is rotated so that the two limit sliders 9 will slide horizontally in the corresponding limit sliders 10. After the two limit sliders 9 have finished rotating, the two trapezoidal blocks 11 will be reset under the support of the corresponding springs 14, so that the two trapezoidal blocks 11 will contact with the corresponding limit sliders 9, thereby facilitating the limiting and fixing of the two limit sliders 9. When disassembling the monitoring camera 1, it is only necessary to pull the two installation rods 4 to disengage the two trapezoidal blocks 11 from the corresponding limit sliders 9, thereby facilitating the disassembly of the monitoring camera 1.

[0035] Through the cooperation of the plug-in column 8, two installation rods 4, two springs 14, two limit plates 13, two trapezoidal blocks 11 and two limit sliders 9, the two limit sliders 9 can slide in the corresponding limit slide grooves 10, thereby facilitating the rapid fixation of the surveillance camera 1, so that the two trapezoidal blocks 11 will fix the two limit sliders 9 under the support of the corresponding springs 14, thereby preventing the surveillance camera 1 from loosening or detaching when subjected to external collisions, and further improving the stability of the installation of the surveillance camera 1.

[0036] Through the meshing connection between the first bevel gear 5 and the second bevel gear 7 , the first bevel gear 5 can drive the rotating seat 3 to rotate in the mounting bracket 2 , thereby facilitating the adjustment of the angle of the monitoring camera 1 and further improving the use effect of the monitoring camera 1 .

[0037] Working principle: By connecting an external power supply to start the driving motor 6, the driving motor 6 drives the first bevel gear 5 to rotate. Under the meshing connection between the first bevel gear 5 and the second bevel gear 7, the first bevel gear 5 rotates to drive the second bevel gear 7 to rotate the rotating seat 3 in the mounting bracket 2. When installing the monitoring camera 1, the staff will plug the two limit sliders 9 on the top of the monitoring camera 1 into the corresponding limit slide grooves 10, so that when the two limit sliders 9 slide in the corresponding limit slide grooves 10, they will contact with the corresponding trapezoidal card blocks 11. When the plug-in column 8 is slidably connected in the plug-in groove 12, the two limit sliders 9 will compress the corresponding trapezoidal card blocks 11. The trapezoidal blocks 11 are retracted into the corresponding sliding grooves 15, and the two trapezoidal blocks 11 move to drive the corresponding limit plates 13 to move under the guidance of the corresponding sliding grooves 15. The two limit plates 13 move to drive the corresponding installation pull rods 4 to move and compress the corresponding springs 14. Then, the monitoring camera 1 is rotated so that the two limit sliders 9 will slide horizontally in the corresponding limit sliders 10. After the two limit sliders 9 have finished rotating, the two trapezoidal blocks 11 will be reset under the support of the corresponding springs 14, so that the two trapezoidal blocks 11 will contact the corresponding limit sliders 9, thereby facilitating the limiting and fixing of the two limit sliders 9.
