Summary of the invention

In order to overcome the weakness that existing door lock on the market can not effectively limit robber's uncaging time, the utility model lock provides a kind of solution of unblanking in limited time. and this cores time-limiting lock can limit the time of unblanking, thereby make the robber in the limited time, use unlocking tool that lock is cracked, thereby reach antitheft effect.

The utility model lock for solving the technical scheme that this technical barrier adopted is:

A kind of time-delay safety anti-theft lock of unblanking, comprise: lock core, the cylindrical metal rod of one end ball-type, one end class concave character type, the lever of rectangular structure, the sheet metal of L font, one end top is the metal bar pintle hook lock of draw-in groove, the metal derby that a hole is arranged, it is characterized in that: the excellent body of metal bar keeper pin is enclosed within the hole of metal derby, metal derby is fixed on the shell of lock, between metal bar keeper pin and metal derby, be filled with a large amount of damping oils, insert keyhole, touch metal bar as object, cause the upwards skew of lever of rectangular structure again, the sheet metal and the metal bar pintle hook lock of L font can be moved up, do usefulness in the hole of metal derby, increase the time that the metal bar pintle hook lock pins dead bolt but damping takes place metal bar pintle hook lock rod.

In lock, use 2 dead bolts, being respectively upper lock tongue (part 11) and following dead bolt (part 11) down. some is the draw-in groove that depression is gone down for the middle front end of upper lock tongue, become the place of vertical angle with the sunk part draw-in groove, putting the metal bar keeper (part 10) of a top band groove. the band groove metal bar keeper (part 10) can with the mutual interlock of draw-in groove of upper lock tongue (part 11), if will be locked after two mutual interlocks of part, thereby door lock is pinned and can not open upper lock tongue (part 11).

The excellent body of the metal bar keeper pin (part 10) of band groove is enclosed within the hole of a metal derby (part 9), metal derby (part 9) is fixed on the shell of lock. putting a spring that upwards pushes away in the middle of metal bar keeper (part 10) and the metal derby (part 9), spring is given thrust that makes progress of metal bar keeper pin (part 10), thereby makes the metal latching (part 10) can be locked upper lock tongue (part 11) automatically.

Lock core (part 6) then the central authorities of face inserting a metal bar connecting rod (part 7). the part that metal bar connecting rod (part 7) inserts lock core becomes dome-type, the other end is cut into the draw-in groove of class concave character type, can with the interlock mutually of the rectangular structure lever (part 7) of anti-groove. metal bar connecting rod (part 7) is exposed at the outer part of lock core (part 6) a spring to lira, and spring is given power that retracts to lock core (part 6) central authorities of metal connecting rod (part 7).

When having object such as key to insert when keyhole, must push the metal bar connecting rod (part 7) that inserts in the lock core, head is that semicircular metal bar connecting rod (part 7) can be moved to the left under the effect of pressure, the class concave character type draw-in groove of the other end shortens with distance between the rectangular structure lever (part 7), two parts fasten. and the downward-sloping angle of rectangular structure lever (part 7) diminishes, make the sheet metal of L font and rectangular structure lever (part 7) under the effect of self spring thrust, can move up, thereby make the metal latching (part 10) can be locked upper lock tongue (part 11) automatically. but filled a large amount of damping oils at metal bar keeper pin (part 10) with between the metal derby (part 9), make metal latching (part 10) so because the decelerating effect of damping oil has been slowed down the rate of climb of self. when keyhole pins the nearly time difference more than 3 seconds the upper lock tongue (part 11) from inserting object to metal latching (part 10).Rotational lock core pulling two dead bolts up and down if in this 3 second short time, have no idea, upper lock tongue (part 11) thus will have been reached the effect of restriction uncaging time by locked.

After upper lock tongue (part 11) is pinned by metal latching (part 10), the object that inserts keyhole is transferred to, metal bar connecting rod (part 7) in the lock core is got back to original position under the active force of self spring, rectangular structure lever (part 7) is forced to again move down under active force, the sheet metal and the metal bar keeper (part 10) that drive the L font also move down, and untie locked the do usefulness of metal bar keeper (part 10) to upper lock tongue (part 11).The tapered end inner body returns to reset condition again.

The beneficial effect of the utility model lock is, can limit the time of unblanking, and makes the robber can't use other unlocking tools to touch the broken lock of examination pellet shot from a slingshot with the method for exhaustion in the limited time. whole lock simple in structure, cheap, extensive easily the generation and sale.
