Abstract
The utility model discloses a lock body part capable of preventing an anti-theft door from being opened by destroying a lock core. When a thief destroys the lock core 11 by using a special violent unlocking tool to break the lock core 11, a transmission stressed piece 1 which is adjacent to the lock core is pushed by a spring to move backwardly, a sliding piece 2 which is adjacent to the lock core is pushed by a spring to unlock a bolt 10 in a bolt hole 9, and the bolt 10 is sprung by a spring 15 in the bolt hole 9 to block the bolt hole in the anti-theft door 17, so the thief cannot shift an anti-theft door lock bolt transmission piece 13, cannot open an anti-theft lock and cannot open the door. Therefore, the thief cannot enter a house, so the property safety of a house owner is ensured.
Description
Technical field
The utility model relates to a kind of Mechanical theft-proof door lock technical field
Background technology
The all traditional core of known security door lock body is mixed mechanical system and is formed by connecting, and adopts lock body and core make-up machinery structure and forms, and theftproof performance is very poor; A whole set of lock transmission mechanism is all with lever; Sliding block spring, combinations such as alignment pin, robber's special tool that uses force destroys core; Be easy to open security door and go into indoor theft, its house-owner's property is incurred loss.
The utility model is exactly in the security door lock body, establishes the tamper-proof lock cylinder device of a cover in addition near the core place, when core is destroyed by the invador; Its antitheft lock device starts immediately; Stressed of antitheft transmission and slide motion, slide presses vertical pin of doing to eject stuck safe-guard door lock bolt, makes its invador can't open safe-guard door lock; Avoid invading the robber and get into the room, effectively protect house-owner's property safety.
The summary of the invention type
The purpose of the utility model is to remedy existing safe-guard door lock technical deficiency and a kind of all-round anti-theft device that provides.It is characterized in that by traditional core, a cover novel anti-theft device is installed separately.
Accompanying drawing 1 is formed slide by 2 iron plates, and slide 2 is inserted in 4 locking bolt chocks, the 6 slip film traps during use.
Bore a function screw fixing hole 3A at accompanying drawing 4 slide side-looking faces, accompanying drawing 6 antitheft component body are drilled with function screw hole 3B and overlook face with accompanying drawing 4 slides and on same line, be convenient to installation.
Accompanying drawing 7 antitheft component body side-looking faces are designed with the function screw hole, and slide is pressed and done pin, and pin hole inner spring is in compressive state at ordinary times.
Fig. 9 component body of guarding against theft is overlooked face one pin hole is arranged; Spring is arranged below the pin, below slide, pushes down at ordinary times, when the invasion robber use force core destroyed cause the core fracture after; Stressed of the transmission of antitheft part device is laterally ejected; Slide moves, and pin ejects immediately, stuck security door locking bolt.
The utility model beneficial effect is, utilizes the security door core to destroy the back under spring action, impels slide to move, and pin ejects immediately, and stuck security door locking bolt makes it can't open security door.Compare its safety and reliability with traditional security door.

Accompanying drawing 10 pins,
1. the pin hole 18. anti-theft feature screws on stressed flat spring 17. security doors of screw hole 9. pin holes 10. pins, 11. cores, 12. security door locking bolts, 13. security door locking bolt driver blades, 14. safe-guard door locks, 15. pin sliding springs, 16. transmissions of stressed A of transmission 2. slide B 3. function screw fixing holes 4. antitheft component body 5. spring eyes 6. slip film traps 7. locating slots 8. fixing antitheft component body are formed
The specific embodiment
Do to further describe below in conjunction with 2 pairs of the utility model of accompanying drawing, as shown in the figure, 4. 7 locating slots on the antitheft component body; Be installed in 12 security door locking bolts and be close to, fix with screw, after locking lock with key in 8 place; Pin hole on 17 security doors is just in time aimed at 6 slides pressure and is done 10 pins in the 9 pin holes; After installing 10 cores, remove 18. anti-theft feature screws, stressed promotion of 16 spring handles, 1 transmission makes 11 cores stressed.
Looking face on 4 antitheft component body upside left sides has one 5 slide spring eyes, places spring in the hole in, and the function screw is pushed down slide and made slide overlook face to push down 5 inner springs, make its 5 spring be in compressive state during installation, and 5 slides just in time are close to core at this moment.
When the use force special tool of unblanking of invasion robber destroys 11 cores, cause the fracture of 11 cores, this moment near stressed 2 slide of 1 transmission of core under the spring impetus; Stressed of 1 transmission slides backward, and 10 pins that 2 slides are sealed in the 9 pin holes are opened, and 15 spring handles, 10 pins in the 9 pin holes are upspring simultaneously; Block the pin hole on 17 security doors; Make the invasion robber can't dial 13. security door locking bolt driver blades, cause the invasion robber can't open theftproof lock, the lock door of not opening then can not be opened; Reach like this to prevent to steal and compose entering within doors, thereby guarantee house-owner's property safety.
