In security engineering, monitoring racks are an indispensable and important component. Monitoring racks provide a stable installation platform for monitoring cameras. Their installation position and height directly determine the field of view and monitoring effect of monitoring cameras. They can effectively monitor specific areas in real time, detect abnormal situations in time and provide a basis for subsequent processing, thereby playing a key role in maintaining public safety, preventing crime, and protecting property safety.
[0003] Existing monitoring frames used in security projects usually adopt a relatively simple fixed structure design. They are generally composed of a fixed base, an upright support rod and a fixed frame for installing monitoring equipment. The support rod is mostly a single integral structure, fixed to the base by welding or bolting. The monitoring equipment is directly installed on the fixed frame at a predetermined height. After installation, the overall structure is relatively fixed and lacks mechanical components for flexible adjustment of the monitoring height.
[0004] However, this traditional fixed structure makes the monitoring frame for security engineering relatively fixed when in use, and it is impossible to easily adjust the operating height of the monitoring equipment according to actual monitoring needs, resulting in a limited monitoring range and difficulty in meeting the requirements of different monitoring heights in some special scenarios or changing environments, thereby affecting the overall effectiveness of the security monitoring system. Therefore, a monitoring frame for security engineering is proposed to solve the above problems. Utility Model Content

The second shaft 8 is fixedly connected to the outside with a ratchet 11, which is used to cooperate with the pawl 13 to form a one-way locking device. The side wall of the outer frame 3 is fixedly connected to a fixing plate 12, which is used to provide a stable installation base for components such as the pawl 13. The side wall of the fixing plate 12 is rotatably connected to the pawl 13, which is used to effectively prevent the second shaft 8 from rotating when the crank 10 stops rotating, thereby maintaining the second support The height of the rod 2 is stable. The side wall of the fixed plate 12 is fixedly connected to the first connecting rod 14. The side wall of the pawl 13 is fixedly connected to the second connecting rod 15. A spring 16 is fixedly connected between the first connecting rod 14 and the second connecting rod 15. The spring 16 is used to provide elastic force for the pawl 13 to reset, so that the pawl 13 can maintain the engagement state with the ratchet 11 when not disturbed by external forces, ensuring the stability and reliability of the entire lifting mechanism. The first gear 5 is engaged with the rack 6, the third gear 9 is engaged with the second gear 7, and the pawl 13 is engaged with the ratchet 11.
[0033] When using the device, first, turn the crank 10. The crank 10 serves as a power input component, and its rotation can transmit the torque applied by manpower. The crank 10 drives the second shaft 8 to rotate. The second shaft 8 serves as a transmission component, and plays the role of connecting the crank 10 and the third gear 9, so that the third gear 9 rotates accordingly. Under the meshing action of the third gear 9 and the second gear 7, the meshing structure can accurately transmit power and change the direction of force, so that the second gear 7 rotates. The rotation of the second gear 7 drives the first shaft 4 connected thereto to rotate, and then the first gear 5 rotates. Under the action of the meshing of the first gear 5 and the rack 6, the meshing mechanism converts the rotational motion of the gear into the linear motion of the rack 6, driving the rack 6 to move. The rack 6 is a component connected to the second support rod 2, and its movement makes The second support rod 2 also slides inside the first support rod 1. In this way, the height of the second support rod 2 can be accurately adjusted to change the installation height of the monitoring equipment, thereby increasing the monitored range. At the same time, when the crank 10 is turned, the ratchet 11 also rotates. The ratchet 11 and the pawl 13 form a one-way locking structure. When the ratchet 11 rotates, it drives the pawl 13 to move. When the crank 10 stops being turned, the pawl 13 is engaged with the ratchet 11 by the force of the spring 16. The spring 16 provides the pawl 13 with a reset elastic force to enable the pawl 13 to stably engage with the ratchet 11, preventing the crank 10 from rotating, and ensuring that the height of the second support rod 2 can remain stable after adjustment. Through the above structure, the height of the second support rod 2 can be adjusted, thereby increasing the monitored range.
[0034] Reference Figure 4The adjusting mechanism includes a mounting plate 17, which is used to provide a reliable support platform for other components above it. The bottom of the mounting plate 17 is fixedly connected to the top of the second support rod 2, and the second support rod 2 is externally rotatably connected to a carrying plate 22, which is used to carry monitoring equipment. The mounting plate 17 and the side walls of the carrying plate 22 are fixedly connected to a protective cover 18, which is used to protect the internal components from external influences. A first threaded rod 19 is provided at the bottom of the top protective cover 18, and a first motor 20 is fixedly connected to the inside of the top protective cover 18. The output end of the first motor 20 is connected to the first threaded rod 19, and the first threaded rod 19 is externally threadedly connected to a first slider 21, which is used to move linearly along the first threaded rod 19. A first connecting rod 23 is rotatably connected between the first slider 21 and the carrying plate 22, which is used to connect the first slider 21 and the carrying plate 22, and convert the linear motion of the first slider 21 into rotational motion of the carrying plate 22. By changing the position of the first slider 21, The supporting plate 22 is driven to adjust the angle in the up and down directions around the connection point with the second support rod 2. The bottom protective cover 18 is fixedly connected to a second motor 24, which is used to provide power for the horizontal monitoring angle adjustment. A second threaded rod 25 is provided at the bottom of the bottom protective cover 18, and the output end of the second motor 24 is connected to the second threaded rod 25. The second threaded rod 25 is externally threadedly connected to a second slider 26, which is used to move linearly along it when the second threaded rod 25 rotates. A monitoring cover 27 is rotatably connected to the bottom of the supporting plate 22, and a second connecting rod 28 is rotatably connected between the second slider 26 and the monitoring cover 27, which is used to convert the linear motion of the second slider 26 into a rotational motion of the monitoring cover 27. The second threaded rod 25 is driven to rotate by the second motor 24, driving the second slider 26 to move, and then the second connecting rod 28 is used to make the monitoring cover 27 swing left and right around the connection point with the supporting plate 22, thereby realizing the horizontal angle adjustment of the monitoring equipment.
[0035] When the monitoring direction needs to be changed, the first motor 20 can be started. The first motor 20 serves as a power source and can convert electrical energy into mechanical energy, outputting a stable torque to drive the first threaded rod 19 to rotate. When the first threaded rod 19 rotates, due to the cooperation between the thread structure and the first slider 21, the first slider 21 moves outside the first threaded rod 19. The movement of the first slider 21 transmits power through the first connecting rod 23. The first connecting rod 23 plays a role in connection and force transmission, driving the supporting plate 22 to swing up and down, thereby changing the monitoring angle of the camera installed on the supporting plate 22 in the vertical direction. At the same time, the second motor 24 is started. The second motor 24 also serves as a power generating device to drive the second threaded rod 25 to rotate. The second threaded rod 25 transmits power through the second connecting rod 28 during rotation due to its threaded structure and the function of related components. The second connecting rod 28 plays the role of connecting and changing the direction of force, driving the monitoring cover 27 to swing left and right, thereby adjusting the monitoring angle of the camera in the horizontal direction. Through the above structure, the monitoring angle of the camera can be easily adjusted, and the camera can be flexibly aimed at the monitoring areas in different directions, thereby improving the comprehensiveness and accuracy of monitoring and meeting diverse monitoring needs.
[0036] Working principle: When using the device, first, the crank 10 is turned to drive the second rotating shaft 8 to rotate, so that the third gear 9 rotates accordingly. Under the meshing action of the third gear 9 and the second gear 7, the second gear 7 rotates, so that the first rotating shaft 4 drives the first gear 5 to rotate. Under the action of the meshing of the first gear 5 and the rack 6, the rack 6 is driven to move, so that the second support rod 2 also slides inside the first support rod 1 to adjust the height of the second support rod 2. At the same time, when the crank 10 is turned, the ratchet 11 also rotates, driving the pawl 13 to move. When the crank 10 stops being turned, the pawl 13 is engaged with the ratchet 11 by the force of the spring 16 to reset, preventing the crank 10 from rotating. Through the above structure, the height of the second support rod 2 can be adjusted, thereby increasing the monitorable range.
[0037] When the monitoring direction needs to be changed, the first motor 20 can be started to drive the first threaded rod 19 to rotate. At this time, the first slider 21 moves outside the first threaded rod 19, and drives the supporting plate 22 to swing up and down through the first connecting rod 23. At the same time, the second motor 24 is started to drive the second threaded rod 25 to rotate, and drives the monitoring cover 27 to swing left and right through the second connecting rod 28. Through the above structure, the monitoring angle of the camera can be easily adjusted.
[0038] 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. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
