For many years, people attempt to address the above problem, mostly is to set about from anti-electricity-theft aspect: propose to adopt the self-locking anti-theft arrangement, as Chinese patent 93205454.4,99237403.0 etc., but this class device has also brought problem to the supvr simultaneously, and measuring apparatus goes wrong sometimes, need open metering outfit inspection by the supvr, but the self-locking anti-theft arrangement often can not be taken apart, takes operation apart and can damage device self, and more changing device has increased bigger extra cost again again.

The utility model content

The device of the invention has a shell and a screw, and screw can be tightened the seat of metering outfit with lid, and is hidden in the shell, plays the characteristics to the device protective action.

Screw of the present utility model and shell constitute loose fit, can make when turning shell, and shell is around screw turns, therefore, have and only turn the advantage that shell can't make screw separate with seat, lid.

The screw of this device is lived its top by lead sealing after seat and lid are tightened, and the operation that makes screw break away from seat, lid must could realize after destroying lead sealing, thereby have the advantages that to allow stealer's change equipment leave a trace.

Therefore, the purpose of this utility model is a kind of anti-pressure ability and antitorque kinetic force with certain intensity will be provided, can leave a trace so that discern the device that makes things convenient for the supvr to open check, can encapsulate again again simultaneously when unauthorized people is changed equipment.

The purpose of this utility model is achieved in that

A kind of identification locking device of lead-sealable actuation comprises screw, shell and the lead nail that is used to seal, and is characterized in, shell is tubular, base seal has a through hole on the bottom, screw is not held by this through hole and stretched out, screw head is limited in the shell inner bottom part, be provided with inner core in the shell, the uncovered of inner core covers the inner core base seal facing to the bottom of shell and with screw head, also have a hole on it, inner core is sealed by lead nail.

During use, tip of screw is coated cementing agent, and the screw of screw aligning equipment lead sealing place is screwed in and tightens, put inner core, fill plumbous material then in the enclosure, adopt specific purpose tool that its extrusion is pushed in the shell together with outshot, can play in the enclosure encapsulation such as inner cores as Fig. 2.

The utlity model has following advantage: when one, installing, tip of screw and bar portion are spun in the equipment screw, and screw head is then stayed in the shell, can't directly touch the screw operation of unpacking from the outside, play the effect to the device protection; Two, because screw head and shell are not fixed, and during rotation case, screw can not followed rotation, therefore, also can't attempt to open equipment, device is played further protective action again by the turn shell; Three, will must cut out plumbous material earlier from turn screw in the shell, this leaves a trace just for change equipment, can be for people's identification; When four, installing, coat cementing agent at tip of screw and can make and terminally fix, play prevention and spur shell and counter-rotating simultaneously and screw is followed closely rotate the effect that breaks away from screw with the equipment screw; Five, above-mentioned safeguard procedures can play sluggish criminal's crime time, so that it is found that, the more important thing is, help preventing that large-scale damage from causing supvr's blurred vision, and the stealer brings difficulty to identification; Six, for the supvr, can cut out lead nail, the screw of outwarding winding is opened equipment, be correlated with unpack after, screw on screw again, and squeeze into lead nail in addition, encapsulate again.
