Abstract
The utility model discloses an anti-theft lock which comprises a lock shell 9 and a rotating shaft 7 used for driving a lock tongue 19 to stretch and shrink. The utility model is characterized in that a supporting shell 11 is arranged on the lock shell 9, the rotating shaft 7 is positioned in the supporting shell 11, and a spring 6 is arranged between the rotating shaft 7 and the supporting shell 1. One end of the spring 6 is abutted on a spring gear 13, and a bearing 8 is arranged between the spring gear 13 and the supporting shell 11. A lock core connected with the rotating shaft 7 is positioned in a lock head 4, and the lock head 4 is positioned in an inner steel jacket 5. The other end of the spring 6 is abutted on the inner steel jacket 5, and the inner steel jacket 5 is positioned in an outer steel jacket 3 and is in key joint with the outer steel jacket 3. The utility model has the advantages of prizing prevention, drilling prevention, etc.
Description
The utility model belongs to a kind of lockset, particularly a kind of pick-proof, anti-drilling door lock.
Existing door lock structure is to be supported with a movable plate in the lock housing, and a termination of movable plate connects dead bolt, and movable plate is complementary with the cam that is supported on the lock housing, cam leans on the driving lever that links with rotating shaft to stir, move and drive movable plate, make dead bolt flexible, reach the purpose of open and close door.Rotating shaft links with the lock core that is positioned at tapered end.Tapered end is embedded in the body during installation, and the rotation of rotating shaft drives lock core by key and rotates and drive.Its shortcoming is not have anti-drilling, tamper-resistant function, and is destroyed easily, so safety factor is little.
The purpose of this utility model provides a kind of door lock of anti-drilling, pick-proof, to improve security performance.
Technical solution of the present utility model is: a kind of lock, it comprises lock housing 9 and drives the rotating shaft 7 that dead bolt 19 stretches, it is characterized in that: support shell 11 is housed on the lock housing 9, rotating shaft 7 is positioned at it, between rotating shaft 7 and support shell 1, be provided with spring 6, one end of spring 6 leans against on the spring shelves 13, be provided with bearing 8 between spring shelves 13 and the support shell 11, the lock core that connects with rotating shaft 7 is positioned at tapered end 4, tapered end 4 is positioned at steel bushing 5, in the other end of spring 6 leans against on the steel bushing 5, interior steel bushing 5 be positioned at outer steel sleeve 3 and with its key connecting.
Be with a rubber cushion 12 in the described rotating shaft 7.
The termination of described tapered end 4 is provided with backplate 2.
Advantages such as that the utility model compared with prior art has is anti-drilling, pick-proof.
Below in conjunction with the drawings and the specific embodiments the utility model is further described:
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is the structural representation of lock housing in the utility model, movable plate, cam.
As shown in the figure: 9 is lock housing, and two support slots 17 are arranged in the lock housing 9, and support slot 17 upper supports have movable plate 18, and a termination of movable plate 18 has dead bolt 19, when movable plate 18 moves, and dead bolt 19 extended or withdrawals, the purpose that reaches lock or open the door.Movable plate 18 matches with cam 16, and cam 16 is supported in the lock housing 19, and rotatable with respect to lock housing, moves so that drive movable plate.Fixedly be connected to a shelves axle 15 on the cam 16.Lock housing 9 inner bolts are connected with a support shell 11, rotating shaft 7 is positioned at it, be with the rubber cushion 12, spring shelves 13, the spring 6 that are positioned at support shell 11 in the rotating shaft 7 respectively, one end of spring 6 leans on spring shelves 13, be provided with bearing 8 between at the bottom of spring shelves 13 and support shell 11 shells, rotating shaft 7 is provided with driving lever 14, is mobilizable key connecting between driving lever 14 and the rotating shaft 7.Driving lever 14 rides against on the shelves axle 15.The other end and the lock core of rotating shaft 7 join, and the other end of spring 6 leans on interior steel bushing 5, and tapered end 4 is positioned at steel bushing 5, and lock core is positioned at tapered end 4.Interior steel bushing 5 is positioned at outer steel sleeve 3, and with its key connecting.The outer steel sleeve port is inlaid with backplate 2.
By screw hole 10 usefulness screws outer steel sleeve 3 fixedly is embedded in the door during installation, lock housing 9 is fixed on the inboard of door.Stretch in the lock core with the hole 1 of key on backplate 2 when opening the door and rotate, lock core drives rotating shaft 7 and stirs shelves axle 15 by driving lever 14 cam 16 is rotated, thereby drives movable plate 18, dead bolt 19 is flexible.Prized, when drilled, because lock core is subjected to an axial force to the door inboard, make lock core, rotating shaft 7, tapered end 4 when lock core, interior steel bushing 5 is together to the door medial movement, and this moment, spring 6 was compressed, and played cushioning effect, can prevent being prized damage.When interior steel bushing 15 move a certain distance and make it and outer steel sleeve 3 between key when breaking away from, key between driving lever 14 and the rotating shaft 7 also breaks away from, lock core, rotating shaft 7, tapered end 4, interior steel bushing 5, spring 6 are together with drill bit rotation (i.e. idle running at this moment, can not drive cam 16 rotates, dead bolt 19 also maintains static), to prevent the thief door is opened.
