The purpose of this utility model be exactly to provide a kind of and integrate that preventing universal key is opened, the combined antitheft mechanical code lock of anti-other technologies unlatching, anti-eavesdrop, anti-drilling, pick-proof.
For reaching this purpose, the antitheft mechanical code lock that the utility model is designed comprises lock housing body and anti-drilling panel and alarm etc., and the lock housing body is divided into two spaces up and down by the intermediate layer.Be provided with the password gear train that three pairs are made of code wheel and master gear in the front portion in last space, the axle of password gear train is equipped with on the core and pushes away frame, pushes away the other end of frame and links to each other the formation password number of changing mechanism with push rod on being installed in the lock housing body.Correspondingly be provided with three pairs by the key bit wheels that constitute from gear and master key cam at the rear portion in last space, wherein on the secondary key bit wheels warning wheel is housed, the circumference of warning wheel is provided with collets, the warning wheel steel wire of alarm contacts with the warning wheel periphery, on second mate's key bit wheels alert sheet is housed respectively in addition, the circumferential distribution of alert sheet has flange, and the alert sheet steel wire of alarm is arranged between the two flanges and warns the sheet Intermittent Contact.Alarm constitutes alarm circuit by warning wheel steel wire, warning wheel, alert sheet, alert sheet steel wire.Rear portion in following space is provided with main lock core, and the below corresponding to each master key cam on the intermediate layer of main lock core and lock housing body has at least one pellet shot from a slingshot hole, and upper and lower pellet shot from a slingshot and spring are housed in it.Constitute the password pellet shot from a slingshot alarming lock of going up of the present utility model by above-mentioned password gear train, key bit wheels, alarm, pellet shot from a slingshot and main lock core.Be provided with a little lock core that is connected as a single entity with main lock core in the following front portion in space, have several pellet shot from a slingshot holes on little lock core and the corresponding lock housing body thereof, pellet shot from a slingshot and spring are housed in it, control little lock core by key and rotate, constitutes of the present utility model under traditional cylinder lock.On corresponding to little lock core anti-drilling panel foremost, be embedded with anti-drilling dish.
Above-mentioned anti-drilling dish can be made into anti-lock dial, and can be provided with and anti-lock dial common unlock chip assembly that be used, that be mainly used in the safety cabinet class in the rearmost end of above-mentioned main lock core, constitutes password scale dish lock down of the present utility model thus.
Advantage of the present utility model be it will go up password pellet shot from a slingshot alarming lock, down traditional cylinder lock and/or down password scale dish lock organically combine together, several locksets are not only with lock body but also same lock core, interrelated, all linked with one another, automatically report to the police, lack arbitrary link and all can not unblank, have multiple functions such as preventing universal key is opened, anti-drilling, pick-proof, anti-eavesdrop, particularly its anti-technical opening time was greater than 24 hours.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is a kind of structural representation that is used for the combined antitheft mechanical code lock of safe door;
Fig. 2 looks schematic diagram for the left side of Fig. 1;
Fig. 3 is the A-A cross-sectional schematic of Fig. 1;
Fig. 4 is the B-B cross-sectional schematic of Fig. 1;
Fig. 5 is the alarm circuit schematic diagram;
Fig. 6 is the another kind of structural representation that is used for the combined antitheft mechanical code lock of door.
The combined antitheft mechanical code lock that is used for safe door shown in the figure, have lock housing body 4 and with the anti-drilling panel 3 of its riveted and alarm etc., lock housing body 4 is divided into two spaces up and down by the intermediate layer.
The password gear train that three pairs are made of code wheel 31 and master gear 30 is housed on the front axle core 32 in last space and pushes away frame 28, pushing away the other end of frame 28 is threaded with screw putter 29 on being installed in lock housing body 4, loosening push rod 29 can make a core 32 move in axle core hole, thereby make throwing off of master gear 30 and its engagement, change code numbers so that stir code wheel 31 from gear 23.Three pairs correspondingly are housed by the key bit wheels that constitute from gear 23 and master key cam 25 on the rear axle core in last space, on the middle secondary key bit wheels warning wheel 26 are housed, be embedded with collets on the circumference of warning wheel 26.The warning wheel steel wire 22 of alarm is contacted with warning wheel 26 peripheries by the screw location.On second mate's key bit wheels alert sheet 24 is housed respectively in addition, the periphery design of alert sheet 24 has six uniform flanges, and two alert sheet steel wires 20 of alarm are separately positioned between the flange of each alert sheet 24 by two screws, 18 location, with alert sheet 24 Intermittent Contact.Be provided with dottle pin 27 between every secondary key bit wheels with insulation.The power supply of alarm and loudspeaker can be installed in outside the lock housing body 4, electric current by positive source by alert sheet steel wire 20, alert sheet 24, warning wheel 26, warning wheel steel wire 22 to the loudspeaker to power cathode, constitute alarm circuit.
On corresponding to little lock core 37 anti-plane of structure plate 3 foremost, be embedded with anti-lock dial 2, and the unlock chip assembly that is used with anti-lock dial 2 be housed in the rearmost end of main lock core 5.The unlock chip assembly is a prior art, is made up of unlock chip 9, unlock chip dottle pin 10, unlock chip screw 11, cover tower bolt 12, sleeve pipe 13 and sleeve pipe spring 14.Rear plate 8 links to each other with lock housing body 4 by screw 15 among the figure, and label 21 is the cover screw of lock housing body 4.
During the utility model work, the code wheel 31 of a secondary password gear train in the middle of at first stirring, by master gear 30, from gear 23 drive master key cams 25 and warning wheel 26 rotations, make corresponding to the last pellet shot from a slingshot 19 of master key cam 25 belows and following pellet shot from a slingshot 7 displacements to be on the critical surface in main lock core 5 and lock housing body 4 intermediate layers, warning wheel steel wire 22 is on the collets on warning wheel 26 circumference.Stir other second mate's password gear trains then, each code wheel 31 is pulled out to the code number of setting, this moment, all last pellet shot from a slingshot 19 and following pellets shot from a slingshot 7 all were on the above-mentioned critical surface.Again key 1 is inserted in the little lock core 37, aim at the anti-graduation mark of locking on the dial 2, make the breach unanimity of three unlock chips 9 in the unlock chip assembly, safe door can be opened by mode clockwise and counter-rotating.If not by the above-mentioned steps operation, then warning wheel steel wire 22 is in warning wheel 26 and contacts conducting state, when stirring other code wheels drive master key cams 25 and 24 rotations of alert sheet, flange on this alert sheet 24 contacts again and again with corresponding alert sheet steel wire 20, alarm circuit is connected frequently, and loudspeaker pipes and plays the effect of automatic warning.
