The utility model is provided with a steel protecting cover with strong anti-damage capability on the lock, and the lock core which is weakness of the lock is protected in the cover body so that the direct aggression for the lock core is effectively repressed by utilizing an electric drill or other picklocks, and the utility model performs the actions of reducing and repressing the occurrence of theft cases.

Description

The antitheft guard shield of a kind of lockset

Technical field

The utility model relates to a kind of antitheft parts of lockset, specifically a kind of antitheft guard shield of lockset.

Background technology

Various places bicycle theft at present and burglary phenomenon are very serious, and the anti-theft feature deficiency of used lockset is an one of the main reasons wherein.Traditional lockset is opened for convenient, outside all lock core being exposed to.And lock core plumbous aluminium alloys or the copper materials of adopting are made more, are the weak parts of lockset, and it is difficult to take precautions against the attack of adopting pirate of the open lock modes such as prizing, cut, disclose.Also have some robbers directly to use small-sized Electric portable drill, can within several seconds, the lock core brill be opened, lockset was lost efficacy, and then theft.Therefore, expose the lock structure of lock core, for antitheft work has brought very big difficulty.

The utility model content

The purpose of this utility model just provides a kind of antitheft guard shield of lockset of special protection lock core, to improve the theftproof performance of lockset, suppresses the frequent generation of theft phenomenon.

The utility model is achieved in that the antitheft guard shield of lockset is the capping face that the other end of at one end uncovered tubular cover body is provided with the band centre bore, have the cylindrical void that is communicated with centre bore on capping face, the edge of cylindrical void is communicated with the key socket that is positioned at faceshield side wall end or capping face edge; On cover body, be provided with and be used for lockset is fixed in the guard shield or guard shield is fixed on connecting elements on the lockset.

Corresponding with the use of the antitheft guard shield of this lockset, be the shape of key need be done appropriate change, promptly the rear end of key becomes one section elongated handle, and the rear end of elongated handle can make that flat, U-shaped or T shape etc. are multiple is convenient to the form that hand-held key is unblanked.When unblanking, earlier the key front end is inserted cover body by the key socket that is positioned at faceshield side wall end or capping face edge; With the position of elongated handle along the cylindrical void slippage on the cover body capping face to centre bore of key rear end, make the key front end then over against lock core; By controlling elongated handle the key front end is inserted in the lock core again, rotate elongated handle and can open lockset.Adopt opposite step, can successfully take out key.

Design philosophy of the present utility model is exactly by adding protective cover, the lock core on the lockset blocked protect, and it is not directly exposed; The available steel manufacturing of guard shield and capping face thereof, its impact strength is big, to protect lock core effectively, attack and destruction to lockset such as avoids prizing, cut, disclosing.The diameter of the centre bore on the guard shield capping face is tiny, the drill bit that bores lock core can not directly be inserted over against ground or pierces lock core, thereby avoided with attack and the destruction of Electric portable drill to lock core.Can improve the whole preventing destructing performance of lockset thus.

The utility model is by being provided with a steel protective cover that survivability is strong on lockset; weakest link with lockset---lock core is protected in cover body; so just can suppress to utilize electric drill or other picklocks to the directtissima of lock core effectively, play the effect that reduces and suppress the larceny case generation.

Description of drawings

Fig. 1, Fig. 3 are the structural representations of two kinds of embodiments of the utility model.

Fig. 2 is the cross-sectional view of Fig. 1.

The specific embodiment

As shown in drawings, an end of the cover body 1 in the utility model is uncovered, and the other end has capping face 2.Capping face 2 can be made one with cover body 1, also can weld together.On the capping face 2 of cover body 1, have centre bore and the slice hole 3 of diameter much smaller than lock core diameter.The inner end of cylindrical void 3 is communicated with centre bore, and marginal end is communicated with the key socket 4 (Fig. 1) that is positioned at cover body 1 side.Key socket 4 also can be opened at the edge of capping face 2 (Fig. 3), and its big I designs according to the size of lockset key with matching.

The shaped design of cover body 1, a kind of is that lock body profile with lockset is complementary.Tubular cover body 1 as shown in Figure 1 and Figure 2, use can match with the lock cylinder 10 of the steel wire lock of locking for bicycle; Flat square tube shape cover body 1 is the use that matches with common padlock body.The another kind of shaped design of cover body 1 is to be the use that matches with built-in lock that uses on door leaf or theftproof lock, can be the various forms of tubular or knob formula therefore.

On cover body 1, also be provided with and be used for lockset is fixed in the guard shield or guard shield is fixed on connecting elements on the lockset.Among Fig. 1, connecting elements be used for fixing the cover in lockset, open perforation 6 and drift bolt 8 on faceshield side wall.Perforation 6 can be circular hole or screw, and drift bolt 8 can be rivet or screw.Among Fig. 3, connecting elements be used for cover body be fixed on lockset, be positioned at the flanging 9 of cover body opening end and on flanging 9, leave fixing with the perforation 6.Perforation 6 can be circular hole or screw, by screw or bolt cover body 1 is fixed on the lock body of built-in lock or theftproof lock.

As shown in Figure 2, the cover body 1 in the utility model is a tubular, wherein is placed with the anti-drilling guiding block 7 with tubaeform centre bore.The effect of anti-drilling guiding block 7, the one, can will stretch into the front end of the key in the cover body 1, by anti-tubaeform centre bore, successfully direct in the lock core hole of rear portion on the other side, so that unlock operation; The 2nd, in case there is bit drills fashionable; anti-drilling guiding block 7 can rotate with drill bit in cover body 1; will make electric drill be difficult to bore anti-drilling guiding block 7 like this and arrive the lock core of back, thereby protect the safety of lock core effectively, further improve anti-drilling performance of the present utility model.

For with the supporting use of steel wire lock, the utility model is also left locking bolt socket 5 at the sidewall of tubular cover body 1.During use, lock body 10 that will steel wire lock inserts in the cover bodies 1 and by connecting elements to be fixed, the locking bolt socket 5 of its lockhole on the cover body 1.Like this, the locking bolt head of steel wire lock can pass locking bolt socket 5, inserts in the lockhole on the lock body 10 locked.
