The latch type anti-theft door lock has the characteristics that the anti-theft door lock has a simple structure, can be dually anti-theft, can defend the master key and can be anti-prying, has very high safety performance and is suitable for being installed on the doors of the house and the vehicle.

Description

No lock core bolt-type safe-guard door lock
Technical field
The utility model relates to a kind of lockset, particularly a kind of no lock core bolt-type safe-guard door lock.
Background technology
Existing safe-guard door lock, great majority all are to adopt key unlocking, and the lock core of this safe-guard door lock generally all is to be exposed to outdoors, so the lawless person is easy to by master key just door-lock opening, or by applying violence door lock are pried open; Some distance type electric door locks also occurred on the market now, though this door lock does not have lock core to be exposed to outdoors, structure is more complicated all, and antijamming capability is relatively poor.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of simple in structure, no lock core bolt-type safe-guard door lock that security performance is high is provided.
The technical scheme that solves the problems of the technologies described above is: a kind of no lock core bolt-type safe-guard door lock, this theftproof lock is directly installed on the door back that has former lock, it comprises housing, be installed in the power supply on the housing base plate respectively, receiver of remote-control sytem, electromagnetic valve and be positioned at housing outer and with the matching used remote control transmitter of receiver of remote-control sytem, described power supply, receiver of remote-control sytem, electromagnetic valve connects by circuit successively, described electromagnetic valve has a valve rod, the end of valve rod is connected with at least one latch by junction plate, also be provided with spring between described electromagnetic valve end face and the junction plate end face, a holder that has the latch pilot hole also is installed on the described housing base plate, and the latch pilot hole that described latch passes this holder stretches out outside the housing.
Further technical scheme of the present utility model is: described power supply reaches the charger that is connected with dry cell by dry cell and forms.
Described housing base plate is made by the steel plate of 4~6mm.
Described latch is the stainless steel latch.
Because adopt said structure, the no lock core bolt-type safe-guard door lock of the utility model is compared with existing safe-guard door lock, has following beneficial effect.
1, simple in structure:
The utility model only comprises housing, is installed in power supply, receiver of remote-control sytem, electromagnetic valve and remote control transmitter on the housing base plate respectively, and wherein each component all can directly be bought back from the market, and structure is very simple, and cost of production is also lower.
2, security performance is very high:
(1) but double anti-theft:
Because the utility model is to be directly installed on the door back that has former lock, therefore, on the antitheft basis of the former lock in first road, installs this nothing lock core bolt-type safe-guard door lock at the door back side, can reach the purpose of double anti-theft.
(2) but preventing universal key and pick-proof:
Because the utility model is mounted in a back, there is not the lock core of this theftproof lock to be exposed to outdoors, therefore can not only effectively prevent the lawless person by master key door-lock opening, can also prevent to apply the purpose that the violence damage theftproof lock reaches pick-proof by other illegal solution lock tool.
(3), anti-drilling:
Owing to can't know at all that outdoors a back also is equipped with this theftproof lock, more can't judge the particular location that door lock is installed, so the utility model can prevent from effectively to hole at the lock core place.
(4), anti-pulling out:
Thick steel plate is done the housing base plate because this nothing lock core bolt-type safe-guard door lock adopts 4~6mm, and is connected on the door-plate by many rivets, applies violence and opens by force so can keep out effectively with various, reaches and prevents pulling out purpose.
(5), anti-tampering:
Because the utility model is to utilize spring thrust to promote latch to lock, so no matter how the external world disturbs and can both normally lock.
(6) prevent Danger Electric shock risk:
Because the utility model is to use six volts of dry cells to do power supply, can not cause Danger Electric shock risk to human body, and works as the situation that family has a power failure, also can normally use in the same old way.
(7), anti-expert's level technical opening:
Because this theftproof lock is mounted in indoor, add that no lock core is exposed to outdoors, and latch is the stainless steel latch that adopts stainless steel material to be made, in the position that can't know the dress lock outdoors at all, want to unblank or picking lock all can't be set about, thereby reach the purpose of anti-expert's release.
3, install, use simple:
Because this anti-stealing and selling is to be directly installed on the door back that has former lock, therefore, need not dismantle former lock during installation, also need not do very big change to door-plate, its installation process is very simple.
The utility model in use, when owner presses down the unlock key of remote control transmitter, receiver of remote-control sytem receives signal and control electromagnetic valve makes its energising, can drive the latch retraction by valve rod after the electromagnetic valve energising, thereby reach the purpose of unblanking; And after electromagnetic valve outage, latch is resetted stretch out outside the housing by being installed in spring between electromagnetic valve end face and the latch end face, thereby reach self-locking purpose, its use operate also fairly simple.
Below, the technical characterictic to the no lock core bolt-type safe-guard door lock of the utility model is further described in conjunction with the accompanying drawings and embodiments.
