Abstract

The invention discloses an anti-falling locking type cable well plugging head device which aims to effectively solve the problem that a plugging device in a cable wiring channel is close to a port of the cable wiring channel in the prior art, so that the plugging device is easy to fall off in the use process. The device comprises a sealing plug which comprises an inner pressing plate, an outer pressing plate and a rubber plugging air bag located between the inner pressing plate and the outer pressing plate, wherein an air bag via hole penetrating through the rubber plugging air bag is formed in the middle of the rubber plugging air bag, and bolt via holes are formed in the middle of the inner pressing plate and the middle of the outer pressing plate respectively; a plug mounting indicating plate which is connected into a wholewith the outer pressing plate through a connecting piece, wherein a bolt through hole is also formed in the middle of the plug mounting indicating plate; and a connecting bolt on which a nut is arranged, and which sequentially penetrates through the bolt via hole of the plug mounting indicating plate, the bolt via hole in the outer pressing plate, the air bag via hole and the bolt via hole in the inner pressing plate.

Description

technical field [0001] The invention relates to a plugging device, in particular to an anti-loosening locking type cable well plugging head device. Background technique [0002] Outdoor cable wells often have rainwater and intrusion of external water sources causing water accumulation in the well. Therefore, during the construction of the cable well project or after the completion of the construction, when no cables are laid in the cable wiring channels between the cable wells, a plugging device is required. Block the ports of the cable wiring channels in the cable wells to avoid the water level between the cable wells being connected through the cable wiring channels, resulting in water ingress in one cable well, causing water inflow in multiple or even dozens of cable wells . [0003] At present, the plugging device for the cable routing channel generally uses a rubber plug to directly block the port of the cable routing channel, or presses the rubber plug through a bolt ...
