Abstract

The utility model relates to an anti-theft, anti-knocking and anti-prizing lock. When the utility model is anti-theft, current flows from a contact point on a key (18) to a parallel winding (29), binding posts (36) (37), a return circuit binding post (8), a lock body (17), a gear set (15), a tongue sheet (26), a lock core (27) and a key body (18) to form a return circuit to start a miniature motor (35) and inch an alarm device inching switch (33), therefore, alarm signals are sent out. When the utility model is knocked and prized, the current flows out of a battery unit (38) in an alarm device switch box and a binding post (43) through a conducting wire, a phase contact point, the binding post (8), a binding post (39) to start a miniature motor (44) and the inching switch, therefore, the alarm device works and sends out alarm signals. When the utility model is unlocked, the current flows from a contact point on the key (18) through an unlocking conducting wire (28), a binding post (7) and the lock binding post (8) of a lock body to start a miniature motor (6) for driving a clamping pin to leave a position. The key is rotate, and the lock can be instantly unlocked.

Description

Antitheft crashproof picking lock

The dynamo-electric antitheft crashproof skid that input power supply and external power matched outside the utility model related to is put.

Reaching nearest newly-designed door lock form at present on the market differs, be difficult to state to the greatest extent, controlling of full machinery with the number machine is two, or the full control of electronic program, they all are by key or by strong, or be converted into the Push And Release that mechanical energy is come control lock by electric energy, and the former key is easy to imitated or the tongue person that decodes is because it makes complexity increases its cost, is difficult to popularize by the people, and they all are that a common shortcoming is arranged for analysis-by-synthesis.No matter in the face of good person or bad person, all be noiselessly quietly to let alone to tease.

The purpose of this utility model is: provide a kind of and modern stereo set that uses at home to match, antitheft, the crashproof lock of forcing open the door of signal can give the alarm, it is no matter you are owner or bad person, an as long as wrong key of usefulness or hit and force open the door, it can both connect the warning device signal that gives the alarm automatically, its warning device can be with ad hoc high pitch alarm or existing equipment, as television set, radio, radio cassette player, video recording video recorder, tranquillization video camera; No matter perhaps various stereo sets and light fixture are that power of alterating and direct current all can use, and particularly car door because of being provided with tweeter on the car, needing only control line is directly inserted at once.

Of the present utility model being achieved in that on lock body (17), key (18) pellet shot from a slingshot group seat (22) lock core (27) gear train (15) dead bolt connecting rod (12) (16) dead bolt (9) (13) is connected, outer input power pack (32) is set is with free dot circuit, the key of contact (18), the band spring contact, unblanking, lead (28) is reported to the police and the insulation plate (42) of company's lead (29), prap (7) micromachine (6), gear (5), bayonet lock (10), static contact (1) (3) and prap (4), breach (19) (20), circuit connection post (8), the warning device switch enclosure, battery pack (38) in the box, micromachine (35) (44), cam (34) (45), point driving switch (33, outer 12～220 volts of praps of warning device of box, knob resets, prap (36) (37 (39) (43), when unblanking, insert the lead (28) that the contact inlet flow of the inside and outside input current of lock core (27) cavity from the key is connected through the spring contact of insulating slab sheet (42) with the key (18) of free dot circuit contact, prap (7), motor (6), from circuit connection post (18) lock body (17) gear train (15), tongue piece (26), lock core (27) key body (18) constitutes loop start motor (6) and is contained in gear (5) on the motor (6) and drives kayser (10) and leave breach on the connecting rod (12), rotates key (18) and drives lock core (27) tongue piece (26) gear train (15) connecting rod (12) (16) dead bolt (9) (13) lock and can open.When stolen, insertion input current outside the not right key of reconnaissance (18) is imported from the contact on the key (18), insulation plate (42) through having spring contact and connect lead (29) prap (36) micromachine (35) prap (37) circuit connection post (8) lock body (17) gear train (15) tongue piece (26) lock core (27) key body (18) and constitute loop start micromachine (35) driving cam (34) crawl warning device switch (33) and connect warning device 12-220 volt power supply, warning device (40) (41) work, signal gives the alarm, when being hit sled, dead bolt fixed frame (2) or lock body (17) modification or off normal and static contact (1) (3) contacts, electric current flows out from the battery pack (38) in the warning device switch enclosure, from prap (43), lead, prap (4), the contact joins, loop line prap (8) lead, prap (39) micromachine (44) constitutes loop start micromachine (44) driving cam (45) crawl warning device switch (33) and connects warning device 12-220 volt power supply, alarm signal is sent in warning device (40) (41) work.Because the warning device switch is a dynamic formula, it need only moment electric current start micromachine (35) (44), this moment, the spring copper sheet of point driving switch promptly played two kinds of effects, the one, as electric conductor, the 2nd, limit cam from horizontal reset as the spacing bayonet lock of cam, guarantee the unimpeded of circuit.Have only with manually removing to press the knob that resets this moment, copper sheet flicked and blocks power supply after cam resetted, report to the police and just can stop, therefore the warning device switch enclosure needs only them mutually with after the lead connection, can be installed in Anywhere in confidence, in case after the warning device work, and be communicated with lead onrelevant, you are exactly with its cut-out, and alarm can not stop yet.So can reach purpose antitheft, crashproof sled reliably.

Owing to taked such scheme, the manufacturing maintenance of this lock easily, its wide accommodation, lock pin off normal and voltage, electric current that the employed micromachine of warning device switch is consumed all little, its power is offed normal as bayonet lock, the required of the closure of switch is pure having a surplus.Therefore brought condition easily to input current, the structure of whole lock is also just simple.
