Abstract
The utility model provides an anti-theft manhole cover which is composed of the manhole cover, a manhole cover base and a gear type key. A bolt is arranged on an outer circle of the manhole cover, and is corresponding to an upper lock mouth arranged on an inner circle of the manhole cover base. The reverse side of the manhole cover is provided with a main and an auxiliary pins which are corresponding to a pin clamp arranged on the inner circle of the manhole cover base. The manhole cover and the manhole cover base are locked and fixed together by the bolt, the lock mouth, the main and the auxiliary pins and the pin clamp. The anti-theft manhole cover of the utility model has the advantages of reasonable design, simple structure, easy manufacture, convenient operation, safety, etc.
Description
The utility model relates to a kind of cable trench, sewer, water-gas underground pipeline well lid that is used to be installed in the highway road surface, specifically a kind of anti-stealing manhole cover that well lid and manhole cover base are locked together.
Be installed in cable trench, sewer, the water-gas underground pipeline well lid on highway road surface, belong to municipal communal facility, but more employed well lids are gone to sell when wastes of iron and steel by some lawless person's thefts often in some local municipal communal facility at present, thereby some uncovered well heads that lack well lid appear on public way, Pedestrians and vehicles was seen to detour and was escaped daytime, but one to night, these well heads that lack lid then were traps one by one, the traffic accident of car crash happens occasionally, and the people's lives and property is caused unnecessary loss.Also there is not at present good way to solve the problem that well lid is stolen by the lawless person.
The purpose of this utility model provides and a kind of well lid and manhole cover base is locked together the anti-stealing manhole cover that prevents that the lawless person from stealing.
The purpose of this utility model realizes in the following manner, anti-stealing manhole cover is to be made of well lid and manhole cover base, circle is provided with dead bolt in the edge of well lid and the manhole cover base that joins with well lid, fore shaft, on the interior circle of manhole cover base, also be provided with keyhole, also be provided with tooth on the edge of well lid, after fore shaft on dead bolt on the well lid edge is justified in manhole cover base enters groove, in the keyhole on the interior circle of gear type key reeve manhole cover base, the wheeled handle on the key of turning gear, stir on the well lid edge tooth by gear and in groove, rotate and the fore shaft dislocation, well lid and manhole cover base are stuck by dead bolt.For tightening security property, again will the gear type key inject in the keyhole in the middle of the well lid and stir main latch with same method, an end of main latch is injected in the manhole cover base in the lock-joint on the circle, well lid and manhole cover base are locked together.Secondary latch has been auxiliary locking effect, when the gear type key is stirred main latch displacement when excessive, secondary latch can inject secondary latch among the lock-joint under the stirring of pusher dog, and the inoperative personnel are difficult to well lid is opened, and main purpose is to increase the difficulty that the thief opens well lid.
Accompanying drawing 1 is the plan structure schematic diagram of anti-stealing manhole cover.
Accompanying drawing 2 is that the A-A of anti-stealing manhole cover is to the cross section structure schematic diagram.
Accompanying drawing 3 is looked up structural representation for anti-stealing manhole cover.
Accompanying drawing 4 is the gear type Key structure schematic diagram of anti-stealing manhole cover.
Explain below with reference to Figure of description anti-stealing manhole cover of the present utility model being done.
