Abstract
The utility model relates to a pry-proof lock which comprises a latch bolt frame arranged in a shell body, wherein a pin hook is arranged in the latch bolt frame; the latch bolt frame is connected with a deflector rod; the pin hook is provided with a rotary shaft which is connected with the latch bolt frame; the pin hook is provided with a guiding post; the shell body is provided with a guiding groove in which the guiding post can move. The guiding groove on the shell body presents a star shape. Because the action of the pin hook of the utility model is controlled by the guiding post on the pin hook and a channel on the shell body, the pin hook which is positioned at the lower side of the utility model does not extend in advance because of self gravity action, and the utility model ensures that the after the pin hook extends into a door frame, the pin hook is opened. The utility model has the advantages of reliable operation and good pry-proof performance.
Description
Technical field:
The utility model relates to security door accessory technical field, particularly a kind of Anti-picking lock.
Background technology:
At present, in the security door technical field, for increasing the pick-proof performance of security door, often be provided with several lock points between the Men Tiyu doorframe, these lock points adopt rod shaped structure mostly, and its pick-proof performance is undesirable.Be head it off, Chinese patent discloses " a kind of lock pin with pin hook " for No. 00205084.6.After having made this kind lock pin on the security door, can make the combination between the Men Tiyu doorframe more reliable.The pin hook that is in downside makes that lock pin work is unreliable because the self gravitation effect often when dead bolt does not also stretch into doorframe, is sold hook and just stretched out.
Summary of the invention:
For solving above defective, the inventor proposed a kind of simple in structure, pick-proof is good, the Anti-picking lock of reliable operation.It comprises: be located at the dead bolt frame in the housing, be provided with the pin hook in the dead bolt frame, the dead bolt frame is connected with driving lever; Described pin hook is provided with rotating shaft, and this rotating shaft is connected on the dead bolt frame; The pin hook is provided with guide pillar, and housing is provided with and can holds the guide groove that this guide pillar moves therein.Guide groove on the described housing is
Shape.
The course of work of the present utility model is as follows: at closing time, locking bar drives driving lever, and driving lever drives the dead bolt frame and stretches out housing, the guide pillar edge on the pin hook
The shape guide groove moves, and when the dead bolt frame stretches out certain-length, forces the pin hook to rotate around its rotating shaft; The pin hook is opened, with the door body and the doorframe locking of security door.
When opening the door, locking bar drives driving lever, and driving lever drives the dead bolt frame and shrinks, the guide pillar edge on the pin hook
The shape guide groove moves, and when dead bolt frame withdrawal certain-length, forces the pin hook to rotate around its rotating shaft; The pin hook is packed up, and finishes the process of unblanking.
Because pin hook action of the present utility model is controlled by guide pillar on the pin hook and the conduit on the housing, the pin hook that is in downside can be owing to the self gravitation effect is stretched out in advance, guarantee just to open after the pin hook stretches into doorframe, its reliable operation, and have better pick-proof performance.
In the utility model, the dead bolt frame is two blocks of sheet materials that link into an integrated entity by steady pin, and the two pin hooks that are provided with relatively are divided into the steady pin both sides, and it is simple in structure, is convenient to manufacture.Housing is provided with dead bolt frame gathering sill, has guaranteed that the dead bolt frame moves at the housing cathetus.Be provided with torsion spring between driving lever and housing; The active force of torsion spring has guaranteed that the dead bolt frame is flexible and has put in place.Described pin hook comprises the pin hook sheet that some plate shapes are identical, the superimposed pin hook that connects into of several pin hook sheet, and the production that it is beneficial to the lock point reduces production costs.Certainly the pin hook also can be made by integral die-cast.
In the utility model, link to each other by pin between described driving lever and dead bolt frame, driving lever is provided with the microscler perforate that is used to pass this pin.Driving lever can be
Shape, a termination portion is provided with rotating shaft, and a termination portion is provided with microscler perforate; Other end head matches with locking bar; It is applicable to the horizontal locking of security door.Certainly, it is shaft-like that driving lever also can be, and its termination portion is provided with rotating shaft, and other end head is provided with the microscler perforate that matches with the dead bolt frame; The middle part is provided with the microscler perforate that matches with locking bar; It is applicable to vertical locking of security door.
