[0001] The utility model relates to the technical field of monitoring rods, in particular to an improved monitoring rod provided with a dovetail through groove. Background Art

[0002] The monitoring pole is a columnar bracket used for installing outdoor monitoring cameras. Road monitoring is usually made with a height of 6 meters and a horizontal arm of 1 meter. Due to the high height of the existing monitoring poles, when the monitoring head is maintained, it is necessary to use a ladder to perform high-altitude operations to remove the monitoring pole for maintenance, which brings safety risks to operators to a certain extent. Therefore, a liftable monitoring pole is set in the prior art.

[0003] A liftable monitoring pole generally has a motor arranged inside the pole body, so a dovetail groove needs to be provided on the pole body to guide the cross arm stably in the vertical direction. However, the applicant found that with wind and rain, rainwater will blow into the pole body through the dovetail groove, causing water accumulation in the pole body, thereby affecting the service life of the motor. For this reason, we propose an improved monitoring pole provided with a dovetail groove. Utility Model Content

[0014] 1. By providing a fixing ring, a circular groove, an arc plate, a connecting plate and a fixing screw, the arc plate can be fixed to block the right side of the dovetail through groove. When it is necessary to lift and lower the monitoring head, the arc plate can be rotated away along the circular groove, thereby avoiding wind and rain. Rainwater will blow into the pole body through the dovetail through groove, causing water accumulation in the pole body, which in turn affects the service life of the motor.

[0015] 2. A liftable top plate is provided on the top of the arc plate through a support spring, so that when the arc plate is rotated, the top plate can be pressed by the handle to avoid hard friction between the top plate and the cross bar, resulting in difficult rotation of the arc plate. After the arc plate is rotated, release the handle, and the top plate can be pressed against the bottom of the cross bar, so that the dovetail through groove can be completely blocked by the arc plate and the top plate, ensuring the rainwater blocking effect.
