Abstract
The utility model relates to a burglarproof device which can strengthen the safety of a built-in lock, and belongs to a burglarproof device matching with the built-in lock. A slide sleeve is connected with a casing by a U-shaped clamp fixedly connected with the casing. A guide pin fixed on the slide sleeve glidingly matches and is connected with a slide way milled at the left end of a lock pin. A fixing bolt is glidingly connected with the lock pin through a connecting pin. A self-locking spring is arranged in a lock pin hole. A door-locking push button is screwed with a fixing bolt. an unlocking spring is sleeved on a fixing bolt, an electromagnet is fixed on the casing, a clamping head vertically fixed on an armature restored by a spring is clamped with the fixing bolt through a groove on the slide sleeve, and a miniature moving-beak switch is fixed on the casing to be connected mutually with the door locking push button through the moving sheet of the miniature moving-break switch. The burglarproof device has the advantages of novel structure and prevention of technical unlocking of locks and destructive unlocking of locks, if cashbox doors, safes, automobiles adopt the timing opening and closing, the doors can not be opened even though the code is known by other people, and the safety of the built-in locks is improved.
Description
Technical field
The utility model belongs to the anti-theft device that the built-in lock with common resident family door, security door, automotive door, national treasury door and safety cabinet is used.
Background technology
In the reality, the built-in lock on the various door is than the advantage of the bright lock of peace, the one, can not judge whether unmanned within doors, the 2nd, relative difficult is destructive opens.But all difficult incessantly skilled unlocking, if the burglar learns unlocking technique or brute force twists off snap or bores lock core down, pacified so any door of built-in lock all dangerous also do not claim antitheft.National treasury door and safety cabinet have transcoding lock in addition except that built-in lock, decryption neither a difficult problem, even coded lock is arranged, compels also can obtain down password in association, in addition defalcates.
Summary of the invention
The utility model provides a kind of anti-theft device that strengthens safety of hidden lock door, with the problem that technical solution is unblanked, destructiveness unblanks to exist.The technical scheme that the utility model is taked is: sliding sleeve 5 is connected with shell by the U-shaped clamp 10 that fixedly is connected on the shell 6, be fixed on the chute sliding connection that guide finger 9 and lock pin 1 left end on the sliding sleeve mill out, positioning bolt 4 is slidingly connected by connecting pin 3 and lock pin or connecting bolt 3 is slidingly connected with lock pin, self-locking spring 2 is in lockpin hole, the button 8 of locking a door is threaded with positioning bolt, the spring 7 of unblanking is socketed on the positioning bolt, electromagnet 11 is fixed on the shell, by groove on the sliding sleeve and positioning bolt clamping, miniature moving disconnection is closed 13 and is fixed on and joins with the button of locking a door by its moving plate on the shell or fixing the contact with dop 12 in the enclosure is connected by the dop 12 of the vertical fixing on the armature of spring reset; Circuit comprises: power supply and electromagnet R11, the moving disconnection are closed Kw13, main switch Kz and connects, and emergency pushbutton switch An disconnects with moving that to close Kw13 in parallel, and main switch backup circuit breaker Kb, hot to lead to K switch t in parallel with main switch Kz.
Main switch Kz adopts regular tap, remote control switch, time switch; The logical K switch t of heat adopts the moving pass of running jointly of thermoswitch, thermistor or bimetallic type.
Its operating principle: a left side is pressed and is locked a door button on earth in the time will locking a door, electromagnet armature dop 12 pops up the positioning bolt right-hand member in the sliding sleeve is blocked, coaxial lock pin moves to left under the elastic force of self-locking spring promotes and puts in the doorframe dead bolt hole, lock a door this moment, dead bolt promotes the lock pin inclined-plane moves to right it, treats that self-locking spring behind the lock tongue slot promoted lock pin again and moves to left and fall into groove and block dead bolt and finish lock again to lock.Unblanking therebetween, spring is compressed accumulation of energy, the moving rotor contact that disconnects pass 13 is pushed down and the still closing of contact by part 8, or after locking a door, sound sheet contact auto-closing; Make power supply, electromagnet R11, moving disconnection close KW13, main switch Kz, electric power loop in the place's connection of moving disconnection pass.This moment, no matter owner, stranger, true key, master key all can't open the door, and twisted off snap, bored that lock core is same down, as long as lock pin is not cut off.
Connect earlier main switch Kz before opening the door, the electromagnet energising is inhaled the moving armature dop and is fallen to discharging positioning bolt, and the spring of unblanking drives the button of locking a door, positioning bolt, connecting pin pulling lock pin and moves to right and discharge the dead bolt release, turns the key in the lock afterwards.The moving disconnection closed the moving plate decompression in the process, or dop inhaled the whereabouts, depresses moving plate, and the sound contact separation is cut off the electricity supply automatically, prevents that electromagnet from continuing that energising is unhelpful to be held heating or burn.The moving disconnection closed also available mini button switch, and rated current is 5-10 a times of operating current.The logical on-off action of heat is in the contingency breaking out of fire, before burning and door or the circuit, and can the automatic processing circuit release.
The utility model advantage is, novel structure can prevent that skilled unlocking, destructiveness from unblanking, and as adopting time switch, even know the password door of also not opening, can eliminate above-mentioned hidden danger to national treasury door, safety cabinet, automobile, improves the safety of built-in lock.
