Abstract

The utility model relates to an anti-theft device of a packing box on a petroleum mine, which is composed of an anti-theft box [1], a one-way self-locking device [2] and a cipher screw bolt [3]. The utility model is characterized in that ratchet wheels of the one-way self-locking device are fixed on the body of the packing box, and ratchet pawls are fixed on the anti-theft box. The anti-theft box [1] is locked by the cipher screw bolt [3]. An upper opening of the anti-theft box [1] is clamped on a press cap of the packing box, and a lower opening is clamped on the body of the packing box. The press cap of the one-way self-locking device used to control the packing box can only rotate positively and can not rotate oppositely. When packing is fastened, the anti-theft box does not need to be opened. If the press cap of the packing box needs rotating oppositely, an exclusive cipher key has to be adopted to open the anti-theft box to relieve the one-way self-locking device. When used, the device provides convenience for oil well operators to fasten packing and prevents lawbreakers from secretly opening the packing box to steal crude oil.

Description

The packing box anti-theft device

Affiliated technical field

The utility model relates to a kind of packing box anti-theft device on the oilfield, and it is used to prevent that the lawless person from dismantling packing box theft crude oil privately.

Background technology

At present, the major defect of known packing box anti-theft device is: must dismantle anti-theft box during tight packing, and especially evening or severe winter, anti-theft box both had been difficult to dismantle, and was difficult to again load onto, and brought greater inconvenience for tight packing.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of packing box anti-theft device, does not need to open anti-theft box during tight packing, has both made things convenient for the tight packing of oil recovery worker, prevents that again the lawless person from dismantling the pressure cap theft crude oil of packing box privately.

The technical scheme that its technical problem that solves the utility model adopts is: the packing box anti-theft device is made of anti-theft box [1], unidirectional self-lock device [2] and password bolt [3].The ratchet of unidirectional self-lock device is fixed on the packing box body, and ratchet is fixed on the anti-theft box, and anti-theft box [1] locks with password bolt [3].Anti-theft box [1] suitable for reading is stuck on the pressure cap of packing box, and end opening is stuck on the packing box body.The pressure cap that unidirectional self-lock device is used to control packing box can only just change, can not reverse, do not need to open anti-theft box during tight packing, want to reverse and to adopt proprietary cipher key to open anti-theft box, remove the individual event self-locking device, therefore, use this device both to make things convenient for the tight packing of oil recovery worker, prevent that again the lawless person from dismantling the pressure cap theft crude oil of packing box privately.

The beneficial effects of the utility model: by field trial, the utility model compared with prior art uses the packing box anti-theft device, has both made things convenient for the tight packing of oil recovery worker, prevents that again the lawless person from dismantling the pressure cap theft crude oil of packing box privately.
