The utility model content
For the shortcoming of the theftproof performance difference that overcomes existing safe-guard door lock, it is a kind of simple in structure that the utility model provides, the Guan Tayong safe-guard door lock that theftproof performance is good.
The Guan Tayong safe-guard door lock comprises knocker, crossette, lock core and key, and knocker is fixed on the doorframe, and crossette is fixed on the door-plate;
It is characterized in that: crossette is provided with through hole, and lock core comprises screw rod and head, the screw rod of lock core pass crossette and with knocker through being threaded; The head of lock core is provided with the key slot, and the key slot is eccentric to be provided with;
Key comprises sleeve part and spanner portion, and sleeve part is fixedly connected with spanner portion, and sleeve part allows the head of lock core to get in it, and the key inserted block adaptive with the key slot arranged in the sleeve part.
Further, the through hole of crossette is a counter sink, and crossette and door-plate welding are fixing; Knocker and doorframe welding are fixing.
Further, the external diameter of the sleeve part of key and the through hole of crossette are adaptive, and the internal diameter of sleeve part and the head of lock core are adaptive; The key inserted block is provided with external screw thread; The key slot is provided with the internal thread with the engagement of key inserted block, and the key inserted block departs from the axis of sleeve part, spanner portion and the coaxial setting of sleeve part.
Further, spanner portion comprises the Handheld Division that is fixedly coupled portion and is convenient to hand with the sleeve part welding.
The advantage of the utility model is:
1, knocker and door-plate are welded into one, are different from traditional door lock, are to adopt bolt etc. to be fixed on the door-plate, and welded construction can be resisted outside destroy.
2, lock core is the eccentric screw structure of machining.
3, the sleeve part external diameter of key and crossette counterbore coincide, and the head dimensions of the sleeve part internal diameter of key and lock core is identical, and the key inserted block in the sleeve part of key just can be opened door lock with the key slot on the head that is arranged at lock core prejudicially is identical; Safe.

The specific embodiment
With reference to accompanying drawing, further specify the utility model:
The Guan Tayong safe-guard door lock comprises knocker 1, crossette 2, lock core 3 and key 4, and knocker 1 is fixed on the doorframe 5, and crossette 2 is fixed on the door-plate 6;
Crossette 2 is provided with through hole 21, and lock core 3 comprises screw rod 32 and head 31, the screw rod 32 of lock core 3 pass crossette 2 and with knocker 1 through being threaded; The head 31 of lock core 3 is provided with key slot 33, key slot 33 eccentric settings.That is to say that lock core 3 is provided with the screw of counterbore for head, and counterbore is eccentric is provided with.
The through hole 21 of crossette 2 is a counter sink, and crossette 2 is fixing with door-plate 6 welding; Knocker 1 is fixing with doorframe 5 welding.
The external diameter of the sleeve part 41 of key 4 and the through hole 21 of crossette 2 are adaptive, and the head 31 of the internal diameter of sleeve part 41 and lock core 3 is adaptive, and key inserted block 43 is provided with external screw thread, and key slot 33 is provided with the internal thread with 43 engagements of key inserted block.The external diameter of the sleeve part 41 of key 3 and the through hole of the crossette 2 21 adaptive sleeve parts 41 of key 3 that are meant can insert in the through hole of crossette 2 just.The head 31 adaptive heads 31 of lock core 3 that are meant of the internal diameter of sleeve part 41 and lock core 3 can insert in the sleeve part 41 just.
The technical conceive of the utility model is: crossette 2 is fixedly welded on the door-plate 6, and crossette 2 serves as the effect of handle simultaneously.The screw rod 32 of lock core 3 passes crossette 2 and knocker 1 and is fixedly connected through screw thread.When unblanking, elder generation inserts head 31, the key inserted block 43 that the sleeve part 41 of key 4 entangles lock core 3 in the key slots 33.Rotary spanner portion 42 then, key inserted block 43 moves in a circle around the axis of sleeve part 41, thereby lock core 31 is screwed out in knocker 1 and crossette 2.When locking, the head 31, key inserted block 43 that the sleeve part 41 of key 4 is entangled lock core 3 inserts in the key slots 33, and reverse rotation spanner portion 42 again is in screwing in lock core 3 knocker 1 and crossette 2 fully.
The advantage of the utility model is:
1, knocker 1 is welded into one with door-plate 6, is different from traditional door lock, is to adopt bolt etc. to be fixed on the door-plate, and welded construction can be resisted outside destroy.
