Description

The four anti-theftproof locks of hiding

Technical field

The utility model belongs to lock technology field, relates in particular to a kind of four anti-theftproof locks of hiding.

Background technology

The lockset that the control room of existing pumping unit of well uses all is three general ring locks or has the lockset of wearing bar.This lockset is installed in the control room behind the door, and the position, next door of lockset offers the opening that hand only can stretch on door, by this mouth lockset cuts out and opens.This lockset by manual saw draw wear bar and lock nose or pound with hammering into shape, crowbar sled etc. is easy to lockset is destroyed, and changes to make illegal oil stealer steal national crude oil insanely, causes greater loss to country.

Summary of the invention

At the problem that above-mentioned lockset exists, it is a kind of simple in structure that the utility model provides, and can prevent saw, pick-proof, anti-pounding, a kind of four antifouling anti-theftproof locks of hiding.

For achieving the above object, the technical solution of the utility model is as follows: this four anti-theftproof lock of hiding has housing and the spring marble head lock core that is positioned at housing, the link gear of the interlock that cooperates with lock core, dead bolt, and the bar of wearing that is arranged on hull outside, and prior art improved, spring marble head lock core is placed and enclosure interior, on housing, be provided with and the corresponding keyhole of spring marble head lock core, on the housing wall of keyhole opposite, be provided with corresponding anti-hole blocking, wear bar and have tapered end in its end, tapered end is provided with draw-in groove, is provided with columniform cavity at the middle part of wearing bar, be provided with anti-in it according to pipe, wear bar and be sleeved in the sleeve pipe, be provided with on sleeve pipe along the slotted eye of quill to setting, manually shift fork is fixed on by slotted eye and wears on the bar; The lockset housing is provided with the Tiaokou of wearing of tapered end insertion, is provided with and wears the insertable guide bushings of bar in wearing the corresponding housing of Tiaokou, and the guide bushings middle part offers the groove that dead bolt can pass through.

Four anti-hiding antitheft Key for lock have key bit, extension bar and handle, and the two ends of extension bar are connected mutually with key bit and handle respectively.

Adopt its beneficial effect of technique scheme as follows: the described four anti-middle parts of wearing bar that hide theftproof lock are provided with columniform cavity, in cavity, be provided with anti-saw pipe, and wearing bar is sleeved in the sleeve pipe, when this is worn bar and uses is to be welded on the iron gate, when drawing when wearing bar sawing in one direction with sawing, when the anti-saw pipe of sawing in wearing bar, because the rolling of anti-saw pipe can't be carried out sawing, reaches the effect of anti-saw.The lockset housing is provided with the Tiaokou of wearing of tapered end insertion, be provided with in wearing the corresponding housing of Tiaokou and wear the insertable guide bushings of bar, the guide bushings middle part offers the groove that dead bolt passes through, when lockset is sealed, wear bar and stretch in the guide bushings, dead bolt is stuck in the draw-in groove on the tapered end by groove.Because guide bushings is to wearing the guiding of bar, and guide bushings and to wear the gap of bar very little, the destruction of crowbar effectively prevented to lockset.Because the spring marble head lock core of this lock and the link gear that cooperates with lock core are arranged on enclosure interior, and spring marble head lock core front shrinking away from theshell body has certain distance, plays and prevents the effect of pounding.On housing, be provided with and the corresponding keyhole of spring marble head lock core, on the housing wall of keyhole opposite, be provided with corresponding anti-hole blocking, can prevent artificial obstruction lockhole.
