[0008] By adopting the above technical solution, when the placement platform drives the rest of the monitoring equipment to move, the lead wire drives the movable block to move in the slide groove, and the wire roller retracts the redundant lead wire.

[0009] Preferably, shaft rods are provided at both ends of the wire roller, sleeves are axially symmetrically provided on the inner wall of the fixing rod, and the shaft rods are axially connected to the sleeves.

[0010] By adopting the above technical solution, the line roller rotates in the fixed rod through the cooperation of the shaft rod and the sleeve.

[0011] Preferably, a torsion spring is arranged in the sleeve, and the torsion spring is sleeved on the outer side of the shaft rod.

[0012] By adopting the above technical solution, the torsion spring reset drives the wire roller to reset through the shaft rod.

[0013] Preferably, the top surface and the bottom surface of the movable block are respectively connected to two ends of a sealing belt.

[0014] By adopting the above technical solution, the movable block moves to drive the sealing belt to rotate, and the sealing belt blocks the slide groove 1 to prevent rainwater from entering the interior of the fixed rod.

[0015] Preferably, an annular groove is provided in the fixing rod, rollers are provided on the top and bottom surfaces of the annular groove, the sealing belt is movably connected in the annular groove, and the sealing belt is tightly wrapped around the outer side of the roller.

[0016] By adopting the above technical solution, the sealing belt is rotated in the annular groove by the roller.

[0017] Compared with the prior art, the utility model has the following beneficial effects: a security monitor with automatic lifting lead drives the screw to rotate through a motor, drives the monitoring device to move up and down through the cooperation of the movable ring and the placement platform, drives the movable block to move up and down in the slide slot one through the lead when the monitoring device moves, recycles the excess lead through the wire roller, avoids the lead from aging and damage due to exposure, prolongs the service life of the lead, and ensures the stability of data transmission.
