Description
Affiliated technical field
The utility model relates to a kind of theftproof lock.It is the anti-theft device of using on a kind of well mouth of oil well door.
Background technology
In the oil well field, the heapstead door lock often takes place to be opened, produce the stolen incident of crude oil, this phenomenon is on the rise.The well mouth of oil well room is opened, and well head and equipment are destroyed, and substantial oil is stolen, has a strong impact on the crude oil ordinary production, makes national wealth be subjected to heavy losses.The analysis main cause is: many oil wells are positioned at rural area or more remote area, and it is unfavorable to keep an eye on; In addition, the theftproof lock that uses at present is that a kind of mechanism is broken or prepares easily key simply, easily and is unlocked.Cause oil well crude oil stolen, even stop production, influence ordinary production.Adopt the coded lock operation more loaded down with trivial details, sometimes the decrypted anti-theft feature that loses of password.Therefore, be opened, produce the stolen phenomenon of crude oil and develop a kind of well mouth of oil well room theftproof lock at the heapstead door lock.
Summary of the invention
The purpose of this utility model provides a kind of well mouth of oil well room theftproof lock, possesses the heapstead theftproof lock that is not easy to be smashed, be not easy to prepare key.The utility model is installed in the well head door, prevents that effectively well head crude oil is stolen, reduce the oilfield economic loss.
The utility model is that the technical scheme that its technical problem of solution is taked is: the utility model mainly is made up of urceolus, inner core and key etc., and it is characterized in that: urceolus is cylindric.Have two tongue holes on the outer tube inner wall at least, the degree of depth in tongue hole is between the 2-8 millimeter.Inner core be one with the mutually inverted cylinder of urceolus, there is 1 screw at the inner core center.Screw is keyhole just.The urceolus internal diameter is than the big 0.3-1 millimeter of inner core external diameter.Interior tube bottom is fixed with at least 2 sliding sleeves.Spring and dead bolt are arranged in the sliding sleeve.What spring adopted is helical spring, and dead bolt is a column, and dead bolt can slide in sliding sleeve.The dead bolt end is fixed with steel wire.The other end of steel wire is fixed on the bearing holder (housing, cover) by pulley.Bearing holder (housing, cover) is circular, and bearing fixing is in bearing holder (housing, cover).The internal diameter of inner core center screw is less than brearing bore, and the external diameter of inner core center screw is greater than brearing bore.Key is made up of handle and screw rod.The screw flight external diameter is greater than brearing bore, and when the screw rod of key screws in the center screw of inner core, the end of screw rod can be pressed on the bearing plane.When the screw rod of key continues to screw in toward the center screw of inner core, the end of screw rod can thrust bearing and bearing holder (housing, cover) move down together.Fixation with steel wire is on bearing holder (housing, cover), and bearing holder (housing, cover) moves down, the pulling steel wire.Steel wire drives dead bolt and moves, and the compression spring.Urceolus barrel hole is withdrawed from the dead bolt end.Urceolus just can separate with inner core, presents unlocking condition; When the screw rod reverse rotation of key, screw out from the inner core center screw, spring releases energy and promotes dead bolt insertion urceolus cinclides.Simultaneously bearing and bearing holder (housing, cover) drive next at steel wire and rise and move up.At this moment, urceolus can not separate with inner core, presents locking state.Key is taken away from locking interior the back-out, do not had the people of key can not open this lock.
The beneficial effects of the utility model are: inner core and urceolus are very firm, are not easy to be broken.The key screw rod is buckled and is adopted the special shape of buckleing, and other screw rod can not screw in.Having the screw rod that adapts with well mouth of oil well room theftproof lock could screw in, and just can open well mouth of oil well room theftproof lock.Special screw rod is not easy by imitated.The utlity model has good anti-theft feature.The utility model is installed in the well head door, can prevents effectively that well head crude oil is stolen, can reduce the oilfield economic loss.
