Description

The antitheft lock device of innovative well lid rain grate

Affiliated technical field

The utility model relates to a kind of novel antitheft well cover locking device, and its function is to set up this lock back city manhole cover can prevent stolenly, belongs to municipal engineering building and maintenance supply.

Background technology

In China city, some well lids that are laid on the road are often stolen by the people at present, and these do not have the well head of lid to give the people's the life and the property band tremendous loss of country.People were in order to address this problem many methods of finding out in the past, as above the iron latticing, go up double-deck well lid or tighten up a screw for the well lid hole and seal wellhole etc.But these new technologies not only do not stop to live well lid to be lost, but also it is huge to inject capital into, and causes double property loss.

The utility model content

The purpose of this utility model provides a kind of well lock and key and well lid, the relevant corollary apparatus of rain grate.As being installed on the old well lid in city, the rain grate, this well lock just can very effectively prevent loss.Bring safety for people's trip.This technology is not only transformed old well lid, rain grate, also can be used on the new product.

The utility model is achieved in that the side in original well lid, rain grate loads onto dead bolt, when manhole cover or rain grate, be inserted in dead bolt in the annular well head or in the catch-basin big lock iron descend to pin.Opposite side (phase the other side) wellhole limit or well lock break iron below mounting shaft lock in well lid or rain grate.Mill out a little side in wellhole or well lock break iron by well lock direction, this side is to the key positioner effect.During the lock well lid, earlier a side of tongue with lock or well lid hook, insert in the well head or lock under the iron greatly well lid is built, key is inserted in the wellhole, in key round bar centre position bilateral symmetry and respectively to mill a long flat side, this flat side mills the locating piece that a restriction height is being overlapped at flat place with the square opening sliding fit on the well lid at locking bar, and this locating piece can guarantee that the angle of casing head on the key faces the spindle nose connection side that well is locked in the time of in key bar inserts wellhole.During the lock well lid, as long as the handle on the key, knob power passed to well lock gear and was with its rotation by key this moment, and tooth bar is moved forward by gear driven, not at annular well head or rainy well lid or the grate of pinning of little lock iron.This well lid has the dead bolt another side tooth bar side to be arranged respectively not under annular well head on one side, therefore well lid or rain grate can't be stolen.Drive a well when covering, key is inserted in wellhole or the keyhole, rotate counterclockwise handle, torsion reaches well lock gear shaft by transmission mechanism and rotates, turn tooth bar withdrawal in well head or little lock iron, hook well lock wellhole or keyhole here again and can open once carrying well lid rain grate.

Owing to adopt such scheme, can make the well lid rain grate cover avoid losing, and also simple in structure easy for installation.
