Technical field

The utility model relates to a kind of lockset, more specifically is meant a kind of theftproof lock.

Background technology

Lockset is used very extensive in daily life, mechanical anti-theft lock and electronic safety lock etc. are generally arranged, electronic safety lock is limited to because of its fancy price application very much, common mechanical anti-theft lock has mechanical latch lock and mechanical shell fragment lock, it is ripe that its application technology has been tending towards, and the appearance of the unlocking tool of each style and the mode of manually unblanking makes traditional lock in the face of very big challenge, no matter be door lock, or the most antitheft institute that uses on the lock for motorcycle, all in use find, increasing people's thief is cut by hydraulic pressure and is stolen, because its lock body of existing theftproof lock or locking bar do not possess anti-structure of cutting, therefore be easy to be cut off.

In addition, because existing theftproof lock keyhole all exposes, cause thief to adopt key of the same type that core is destroyed easily.

Summary of the invention

Main purpose of the present utility model is a kind of theftproof lock simple in structure, easy to use.

Another purpose of the present utility model is to provide a kind of hardness strong, can prevent effectively that other people from adopting hydraulic pressure to cut off the theftproof lock of U-shape lock bar of the present utility model or locking bolt.

The technical solution adopted in the utility model is: a kind of theftproof lock, comprise the U-shape lock bar, locking bolt and lock core, wherein, this U-shape lock bar has first end and the second end, wherein, this first end is corresponding with this second end, this first end is provided with sleeve, this the second end is provided with lockhole to position that should sleeve, this locking bolt is movably set in this sleeve and to being provided with the limited block that can be inserted in this lockhole by the second end, this lock core is fixedly installed on this second end inside, this lock core is provided with locking plate, this locking plate extends to the inboard of this lockhole, and rotatable the moving to this limited block of this locking plate contacts, and this limited block is locked in the inside of this second end by this locking plate.

The inside of this U-shape lock bar and this locking bolt is provided with the anti-layer of cutting.

Layer be should anti-cut and cement layer or layer of concrete were.

This second end sidepiece offers through hole to top that should lock core.

This limited block is provided with locked groove, and this locking plate is rotatable to be moved in this locked groove.

The beneficial effects of the utility model are: the utility model structurally comprises the U-shape lock bar, locking bolt and lock core, wherein, this U-shape lock bar has first end and the second end, wherein, this first end is corresponding with this second end, this first end is provided with sleeve, this the second end is provided with lockhole to position that should sleeve, this locking bolt is movably set in this sleeve and to being provided with the limited block that can be inserted in this lockhole by the second end, this lock core is fixedly installed on this second end inside, this lock core is provided with locking plate, this locking plate extends to the inboard of this lockhole, rotatable the moving to this limited block of this locking plate contacts, and this limited block is locked in the inside of this second end by this locking plate.The inside of this U-shape lock bar and this locking bolt is provided with the anti-layer of cutting.By its special structure design, the utlity model has theftproof lock simple in structure, easy to use, and can realize preventing that other people from adopting hydraulic pressure to cut off the effect of U-shape lock bar of the present utility model or locking bolt.

The specific embodiment

As Fig. 1 to Figure 5 shows that a kind of preferable specific embodiment of the present utility model, a kind of theftproof lock, as shown in Figure 1 to Figure 3, comprise U-shape lock bar 10, locking bolt 20 and lock core 30, wherein, this U-shape lock bar 10 has first end 11 and the second end 12, wherein, this first end 11 is corresponding with this second end 12, and this first end 11 is provided with sleeve 111, and the position that 12 pairs of this second ends should sleeve 111 is provided with lockhole 121.

This locking bolt 20 is movably set in this sleeve 111 and to should being provided with the limited block 21 that can be inserted in this lockhole 121 by the second end 12,

This lock core 30 is fixedly installed on this second end 12 inside, this lock core 30 is provided with locking plate 31, this locking plate 31 extends to the inboard of this lockhole 121, and these locking plate 31 rotatable moving to this limited block 21 contact, and this limited block 21 are locked in the inside of this second end 12 by this locking plate 31.

Further, as shown in Figure 5, the inside of this U-shape lock bar 10 and this locking bolt 20 is provided with the anti-layer 40 of cutting.

Further, this anti-layer of cutting is cement layer or layer of concrete.Physical characteristic by this cement layer or layer of concrete itself strengthens hardness of the present utility model, prevents from easily to be cut off the utility model by other people.Particularly, these the second end 12 sidepieces offer through hole 122 to top that should lock core 30, when the key that is complementary with this lock core 30 inserted the keyhole of this lock core 30, whether the user can observe key from this through hole 122 and be inserted in the keyhole, makes things convenient for the user to unblank or locking.

It should be noted that as shown in Figure 4 this limited block 21 is provided with locked groove 211, these locking plate 31 rotatable moving in this locked groove 211.When this locking plate 31 screwed in to this locked groove 211, the utility model was in lock-out state, is released state on the contrary.

Particularly, through hole 122 has certain distance apart from the top of this second end 12, and because the top of this lock core 30 is corresponding with this through hole 122, that is to say, this lock core 30 is placed in this second end 12 certain degree of depth, the space lengthening so that unblank, and the long enough that must be provided with key that lock core 30 of the present utility model is complementary, could unblank smoothly or locking, on the contrary, if key length can't be unblanked or locking inadequately, the utility model lengthening unblanks can prevent that other people from using key of the same type to open in the space.

What deserves to be mentioned is that the place of unblanking at the top of this second end 12 is provided with the obstruction piece 123 of a crescent shape, increase the difficulty of unblanking by this obstruction piece 123.

Embodiment of the present utility model and accompanying drawing are just in order to show design concept of the present utility model, and protection domain of the present utility model should not be confined to this embodiment.

Can effectively implement by top narration purpose of design of the present utility model as can be seen.The part of embodiment has been showed the purpose of this utility model and has been implemented function and structural themes, and comprised other the replacement that is equal to.

Therefore, right of the present utility model constitutes the equivalence that comprises other to be implemented, and the concrete right scope is with reference to claim.
