Description
[technical field]
The utility model relates to a kind of well lid, especially relates to a kind of cable shaft water-inlet-proof well lid.
[background technology]
At present, along with the quickening of urban construction paces, in order to the integrated environment in city, communication, cable television, traffic signals, power cable pass through buried by a lot of districts and cities, to reduce the visual pollution in overhead, city, original like this electric fixtures on the ground also imbeds underground thereupon, conventional cable shaft " allows a small amount of water to exist in shaft bottom " can use conventional well lid, but buried miniature transformers etc. should possess waterproof requirement " can not bubble ", waterproof measure must be taked, so the well lid of routine just can not adapt to.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of cable shaft water-inlet-proof well lid, by arranging rubber ring in upper cover plate lower annular projection, utilizing tegillum to close two holes, effectively having taken precautions against and entered cable shaft rainwater by the gap between rubber ring and annular plate and two holes.
For achieving the above object, the utility model adopts following technical scheme:
A kind of cable shaft water-inlet-proof well lid, comprise upper cover plate, rubber ring, annular plate and annular ring, annular protrusion is provided with near outer rim place in the bottom surfaces of upper cover plate, the outer edge surface of described annular protrusion is provided with rubber ring, the upper side of upper cover plate is interval with two holes, be respectively equipped with lower convexity ring in the upper cover plate bottom in described two holes, closed the end opening of two protruding rings by two tegillums; The bottom surfaces of upper cover plate outer rim is made on the ring-shaped step of annular plate internal orifice and annular ring.
Described cable shaft water-inlet-proof well lid, in the middle part of the outer edge surface of described annular protrusion, be provided with cannelure, rubber ring set is on described cannelure.
Described cable shaft water-inlet-proof well lid, the end opening of two protruding rings is interval with screw, is each passed through with the screw of screw number of matches the described screw being connected two protruding rings after two tegillums.
Described cable shaft water-inlet-proof well lid, is provided with rubber pad or is coated with glass cement between two tegillums and two protruding rings.
Owing to adopting technical scheme as above, the utility model has following beneficial effect:
Cable shaft water-inlet-proof well lid described in the utility model, when meeting rainy, by arranging rubber ring in upper cover plate lower annular projection, and tegillum closes the protection of two holes formation, has effectively taken precautions against and has entered cable shaft rainwater by the gap between rubber ring and annular plate and two holes; The utility model is applicable to the communication well of built-in device, cable television well, traffic signals well and cable shaft.
