Abstract
The utility model discloses a key-hole built-in-typed antitheft lock, and comprises a lock bolt, a lock body, a lock core and a key, wherein, the lock core controls the lock bolt, the structure of which is characterized in that the key comprises a handle and a barb-shaped jugged end that is arranged at the front part of the handle and is matched with the billiard of the lock core; a key insertion hole is arranged on the lock body; a space that facilitate the appropriate rotation of the key after the jugged end of the key is inserted from the key insertion hole is arranged inside the lock body; a lock core is arranged to be adjacent to the key insertion hole of the lock body; the key hole of the lock core faces towards the space inside the lock body that can facilitate the rotation of the key in an appropriate angle, so that the barb-shaped jugged end of the key can be inserted into the key hole of the lock core. Therefore, the lock core can only be opened with the key with a jugged end being matched with the lock core billiard, thereby improving the antitheft performance.
Description
Affiliated technical field:
The utility model relates to a kind of anti-theft device, especially the theftproof lock that existing any type of master key all can't be opened except that private key.
Background technology:
At present, known all is that keyhole exposes with key operated theftproof lock, in the time will unblanking with key directly insert keyhole then screw key drive lock core and rotate and open.Because the keyhole of lock core exposes, so any type of master key except that the key of unblanking of specially joining can be opened, more brilliant robber uses and moves back and forth some such as fines such as iron wire steel wire insertion keyhole and also can open.
Summary of the invention:
The purpose of this utility model is to provide a kind of except that special bitting other such as master key, steel wire, and things such as iron wire are opened the keyhole internally-arranged type theftproof lock that is difficult for.
The purpose of this utility model is to realize like this, described keyhole internally-arranged type theftproof lock, comprise locking bolt, lock body, lock core and key, lock core control locking bolt, its design feature is the barb-shaped profile of tooth end that matches with lock core marble that described key comprises handle and handle front portion, on lock body, be provided with key insertion hole, the profile of tooth end that is provided with key in lock body enters the space that can allow key rotate proper angle through key insertion hole, key insertion hole adjacent at lock body is equipped with lock core, the keyhole of lock core rotates the space of proper angle facing to the key that can allow in the lock body inwardly, and the barb-shaped profile of tooth end of key can be inserted in the keyhole of lock core.The purpose of this utility model also can be achieved through the following technical solutions, described keyhole internally-arranged type theftproof lock, and its characteristics are cylindrical space or sector space for the space of key rotation proper angle that can allow that is provided with in lock body.
The utlity model has advantage is: any type of master key or other object except that the key of unblanking of specially joining all can not be opened, have only the key of the barb-shaped profile of tooth end that matches with lock core marble that adopts the handle front portion just can open, make theftproof performance more comprehensively, stronger.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a Key structure schematic diagram of the present utility model.
Fig. 3 is that each parts of the present utility model decompose distribution schematic diagram.
Fig. 4 is a structural representation of the present utility model.
Among the figure: locking bolt 1, lock body 2, key 3, lock core 4, latch 5, spring 6, profile of tooth end 7, key insertion hole 8, the space 9 of proper angle.
The specific embodiment:
Below in conjunction with drawings and Examples structure of the present utility model and operating principle and the course of work are elaborated:
As Fig. 1, shown in Figure 2, the utility model comprises locking bolt 1, lock body 2, lock core 4 and key 3, lock core 4 control locking bolts 1, general lock core 4 control latches 5 make it to break away from the draw-in groove position of locking bolt 1, locking bolt 1 ejects under the effect of spring 6, it is characterized in that described key 3 comprises the barb-shaped profile of tooth end 7 that matches with lock core marble of handle and handle front portion, on lock body 2, be provided with key insertion hole 8, the profile of tooth end 7 that is provided with key in lock body 2 enters the space 9 that can allow key 3 rotate proper angles through key insertion hole 8, key insertion hole adjacent at lock body 2 is equipped with lock core 4, the keyhole of lock core 4 inwardly facing in the lock body 2 can allow key rotation proper angle the space and the barb-shaped profile of tooth end 7 of key is inserted in the keyhole of lock cores 4.The space of key rotation proper angle that can allow that is provided with in lock body 2 is generally cylindrical space or sector space, is used to install the lock cylinder (hereinafter to be referred as lock core) of theftproof lock, and the axial length of this cylindrical space is the twice of lock core axial length.The wherein side of cylindrical space have the hole of a lonely shape be called key insertion hole can be described as outside keyhole, an end in this hole is used to insert barb-shaped key through to the lock body outside, the other end communicates with cylindrical space.Lock core is contained in the cylindrical space in lock body front, the keyhole of lock core is towards the inboard of cylindrical space, the keyhole of this lock core 4 is called interior keyhole, the other end of lock core (end that does not have keyhole) is flat with the front of lock body, cylindrical space other half be empty because the axial length of lock core has only the cylindrical space axial length half.This theftproof lock provides a kind of barb-shaped key in addition, when unblanking, the hook-type key inserts then from key insertion hole, and screw key 40 degree (specify: because the axial length of the cylindrical space of lock body is the twice of lock core axial length, the inside still has the remaining space of half behind the former lock core of packing into, and the profile of tooth end length of returning hook portion of barb-shaped key slightly is shorter than the axial length of remaining space, so key can rotate), at this moment keyhole in the buckle of key part is just aimed at, then toward pulling back key, keyhole in the buckle profile of tooth end partly of key all inserts, screw key can be opened again, because the key----of unblanking is hidden in the lock body the inside with colluding the interior keyhole that the hook-type key is complementary, so existing master key or other object can not be opened.
