Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a monitoring device with an angle adjustment structure. Background Art

[0002] The monitoring system is mainly composed of two parts: front-end equipment and back-end equipment. The front-end equipment is usually composed of components such as cameras, manual or electric lenses, pan / tilt heads, protective covers, listeners, alarm detectors and multi-function decoders. They each have their own functions and establish corresponding connections with various devices of the central control system through wired, wireless or optical fiber transmission media. Therefore, monitoring devices are needed. However, the existing monitoring equipment is not convenient to swing during work, which limits the scope of monitoring and reduces the timeliness of monitoring. Therefore, we propose a monitoring device with an angle adjustment structure.

[0003] The Chinese utility model patent with authorization announcement number CN217899408U discloses a monitoring device with an angle adjustment structure. By providing a rotating rod, a mounting tube, a universal joint and the mutual cooperation between the first bevel gear, the rotating rod can be conveniently driven to rotate inside the mounting tube through the mutual cooperation between the second bevel gear and the first bevel gear, and the monitoring head can be driven to rotate through the universal joint. By utilizing the extension and retraction of the electric telescopic rod, the monitoring head can be conveniently driven to flip through the movable sleeve, which can effectively improve the monitoring range and increase practicality.

[0004] In the above, although a certain degree of tilt adjustment can be achieved, it is often unable to provide a large adjustment range due to structural design limitations, especially in the horizontal direction. Moreover, when the monitoring head is adjusted in angle, the traditional movable sleeve is in direct contact with the monitoring head, resulting in large friction resistance. This high friction not only affects the smoothness of the monitoring head movement, but also accelerates mechanical wear and reduces the service life of the equipment.

[0005] Therefore, it is necessary to provide a new monitoring device with an angle adjustment structure to solve the above technical problems. Utility Model Content

[0022] In the specific implementation process, Figures 1 to 4 As shown, the monitoring device with an angle adjustment structure provided by the utility model includes a carrying plate 1, a mounting tube 2 is provided on the top of the carrying plate 1, a rotating rod 10 is rotatably installed inside the mounting tube 2, the outer surface of the rotating rod 10 is fixedly connected to a bevel gear 1, a motor 3 is fixedly installed on the rear end of the mounting tube 2, the output end of the motor 3 passes through the mounting tube 2 and is fixedly connected to a bevel gear 2, the bevel gear 2 is meshed with the bevel gear 1, the top of the rotating rod 10 is movably connected to a monitoring head 12 through a universal joint 11, the bottom of the monitoring head 12 is fixedly connected to a rotating rod 13, the bottom of the rotating rod 13 is fixedly connected to the universal joint 11, the side wall of the mounting tube 2 is fixedly connected to a right-angle plate 4, the side wall of the right-angle plate 4 is rotatably connected to an electric telescopic rod 6, the output end of the electric telescopic rod 6 is rotatably connected to a sliding member, and the sliding member is placed at the bottom of the monitoring head 12.

[0023] By rotating the motor 3 and meshing the bevel gear 2 with the bevel gear 1, the rotating rod 10 can rotate inside the mounting tube 2, and the monitoring head 12 can be driven to move through the universal joint 11, thereby achieving the effect of rotating around the rotating rod 10 as the axis.

[0024] The sliding member includes an annular frame 8, and the inner side wall of the annular frame 8 has a plurality of rotating rollers 9 in an annular array along its vertical axis, and the two ends of the rotating rollers 9 are respectively rotatably connected to the annular frame 8, and the plurality of rotating rollers 9 are in contact with the outer surface of the rotating rod 13.

[0025] Through the extension and retraction of the electric telescopic rod 6, during the extension and retraction process, the electric telescopic rod 6 is extended and retracted with the rotating seat 5 on the right-angle plate 4 as a fulcrum. When extended, the rotating rod 13 will tilt forward with the universal joint 11 as the axis, thereby driving the direction angle of the electric telescopic rod 6 to tilt, that is, the rotating seat 5 rotates on the inner side wall of the rotating seat 7, and with the output end of the electric telescopic rod 6 fixed, the overall structure is stable. Compared with the existing method of controlling the monitoring head 12 toward the top of the electric telescopic rod 6 through the movable sleeve, a larger adjustment angle can be provided.

[0026] By arranging multiple rotating rollers 9 in the annular frame 8, when the rotating rod 10 drives the rotating rod 13 and the monitoring head 12 to rotate through the universal joint 11, the multiple rotating rollers 9 roll on the outer wall of the rotating rod 13, which can reduce friction during rotation compared to the existing movable sleeve directly contacting the monitoring head 12.
