Description
Technical field
The present invention relates to a kind of well lid, particularly relate to a kind of anti-theft cable pit cover.
Background technology
Existing power cable well lid is stolen quantity and is increased year by year.The stolen safe operation to power cable of well lid also exists great hidden danger.And manhole cover loss by cause vehicle, pedestrian injured, cause social danger.
The stolen main cause of existing power cable well lid is:
(1) well lid is that cast iron materials recovery value is high;
(2) well lid inside cable retort stand recovery value is high;
(3) well lid is almost without anti-theft feature.
There is part casting iron well lid to be replaced by glass fibre reinforced plastic manhole covers, but all do not complete so far and more change jobs.Glass fibre reinforced plastic manhole covers because of its recovery value extremely low, sight has been placed on the cable bearer in well lid by stealer, because well lid only has triangle bolt as antitheft.This kind of instrument is copied in a large number in recent years, causes without anti-theft feature.Therefore a novel anti-theft cable well lid is developed extremely urgent.
Summary of the invention
Object of the present invention, exactly in order to solve above-mentioned prior art Problems existing, and provide a kind of anti-theft cable pit cover, can avoid theft well lid.
The technical scheme realizing above-mentioned purpose is: a kind of anti-theft cable pit cover, comprises cylindric base, inner cap, enclosing cover and coded lock, and described coded lock comprises combination disk, lock core pole and unlatching axle, wherein:
The lower nozzle of described cylindric base is with flange;
Described inner cap is round pie structure, and described inner cap is sealed on the lower nozzle of described cylindric base, and is fixedly connected with described cylindric base by some bolts;
Described enclosing cover is round pie structure, and described enclosing cover is sealed on the upper nozzle of described cylindric base, and the soffit of described enclosing cover is in the arc shape protruded downwards;
Described combination disk is arranged on the inside of described enclosing cover;
Described lock core pole is arranged along the axis direction of described cylindric base, and the top of described lock core pole is connected with described enclosing cover, and the bottom of described lock core pole is connected with described inner cap;
Described combination disk is connected with described lock core pole by described unlatching axle.
Above-mentioned a kind of anti-theft cable pit cover, wherein, described enclosing cover adopts glass steel material.
Above-mentioned a kind of anti-theft cable pit cover, wherein, described coded lock adopts 304 stainless steels.
Above-mentioned a kind of anti-theft cable pit cover, wherein, described combination disk adopts two panels mechanical type combination disk, comprises two wheel sheet dishes.
Anti-theft cable pit cover of the present invention, can avoid theft well lid.
Accompanying drawing explanation
Fig. 1 is the structural representation of anti-theft cable pit cover of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the combination disk of anti-theft cable pit cover of the present invention and the connection diagram of enclosing cover.
Detailed description of the invention
In order to make those skilled in the art can understand technical scheme of the present invention better, below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 1, Fig. 2 and Fig. 3, embodiments of the invention, a kind of anti-theft cable pit cover, comprise cylindric base 1, inner cap 2, enclosing cover 3 and coded lock 4, coded lock 4 comprises combination disk 41, lock core pole 42 and opens axle 43.
The lower nozzle of cylindric base 1 is with flange 11; Inner cap 2 is in round pie structure, and inner cap 2 is sealed on the lower nozzle of cylindric base 1, and is fixedly connected with cylindric base 1 by some bolts; Enclosing cover 3 is in round pie structure, and enclosing cover 3 is sealed on the upper nozzle of cylindric base 1, and the soffit 31 of enclosing cover 3 is in the arc shape protruded downwards; Combination disk 41 is arranged on the inside of enclosing cover 3, and combination disk 41 adopts two panels mechanical type combination disk, comprises two wheel sheet dishes 411,412; Lock core pole 42 is arranged along the axis direction of cylindric base 1, and the top of lock core pole 42 is connected with enclosing cover 3, and the bottom of lock core pole 42 is connected with inner cap 2, and namely enclosing cover 3 is connected with inner cap 2 by lock core pole 42; Combination disk 41 is connected with lock core pole 42 by opening axle 43.
Preferably, enclosing cover 3 adopts glass steel material.Coded lock 4 adopts 304 stainless steels, can reach anti-and gets rusty, corrosion-resistant and strength high toughness good, long service life.Coded lock 4 adopts mechanical code lock.
Further, anti-theft cable pit cover of the present invention increases the counterweight of traditional well lid, traditional well lid 40 kilograms, and the weight now through adjustment anti-theft cable pit cover of the present invention reaches 65 kilograms, object is to prevent heavy vehicle through well lid, well lid is upspring and injures automobile or pedestrian by a crashing object.
Anti-theft cable pit cover of the present invention, combination disk 41 adopts two panels mechanical type combination disk, comprise two wheel sheet dishes 411,412, wheel sheet dish 411 and wheel sheet dish 412 form double-digit password, in use, utilize key turns combination disk 41, arrange according to password and answer questions password, opening that axle 43 loosens now can rotation lock core bar 42, is all taken out by lock core pole 42 and can open enclosing cover 3, then twist off some bolts that inner cap 2 is fixedly connected with cylindric base 1, inner cap 2 can be opened.If fruit password is not right, enclosing cover 3 of just not opening, the cable bearer just cannot stolen well lid yet and be placed in well lid.Under coded lock 4 locking-in state, lock core pole 42 can resist the destructive power of 1000 jin.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present invention, should be limited by each claim.
