Abstract
The utility model relates to a cylinder structure, in particular to a burglar alarm cylinder which comprises a movable cylinder and an unlocking driver, a cylinder moving body and a lock core transmission shaft that are installed in the movable cylinder, wherein the lock core transmission shaft is locked with the cylinder moving body through a spring sheet movably installed in a spring sheet hole; the cylinder is characterized in that the cylinder moving body is provided with a trigger block; the movable cylinder is sheathed in a limiting ring; the position of the limiting ring, corresponding to the trigger block, is provided with installing grooves; the installing grooves at two sides of the trigger block are respectively provided with a microswitch; and the trigger end of the microswitch faces towards the trigger block. When a person forcibly twists the cylinder, the trigger block triggers the microswitch, and the alarming device connected with the microswitch can give an alarm, thus achieving the aims of twisting preventing and alarming.
Description
Technical field
The utility model relates to a kind of structure of tapered end, is a kind of Theft-proof and alarming lock specifically.
Background technology
Do not having under the situation of original key, offender's picking lock means are modal to be with boring, cut a hole, bore after the tapered end destruction, twist tapered end by force, lock being opened.This violence damage active methods proportion in theft crime is very high.
Summary of the invention
The purpose of this utility model provides and a kind ofly can prevent that violence from twisting the Theft-proof and alarming lock that tapered end is opened lock by force.
For achieving the above object, the utility model adopts following technical scheme:
Theft-proof and alarming lock described in the utility model comprises movable tapered end, is installed in the driver of unblanking, tapered end mobile, core power transmission shaft in the movable tapered end, the core power transmission shaft locks together by pellet shot from a slingshot and the tapered end mobile that is movably arranged in the pellet shot from a slingshot hole, it is characterized in that: have the triggering piece in the tapered end mobile, movable tapered end is sleeved in the spacing collar, position corresponding with triggering piece in the spacing collar has mounting groove, in the mounting groove of triggering piece both sides a microswitch is installed respectively, the trigger end of microswitch is towards triggering piece.
Between microswitch and triggering piece, return spring is installed.
Adopt after the utility model, when the people twists core by force, trigger piece and can trigger microswitch, the warning device that is connected with microswitch will be reported to the police, and reaches the anti-purpose of turning round warning; When using original key to unblank, trigger piece and can not trigger microswitch.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present utility model;
Fig. 2 is the assembly structure schematic diagram of an embodiment of the present utility model;
The specific embodiment
As Fig. 1, shown in Figure 2, Theft-proof and alarming lock described in the utility model, comprise movable tapered end 1, be installed in the driver 2 of unblanking in the movable tapered end 1, tapered end mobile 3, core power transmission shaft 4, core power transmission shaft 4 locks together by pellet shot from a slingshot and the tapered end mobile 3 that is movably arranged in the pellet shot from a slingshot hole, have in the tapered end mobile 3 and trigger piece 31, movable tapered end 1 is sleeved in the spacing collar 5, position corresponding with triggering piece 31 in the spacing collar 5 has mounting groove 51, in the mounting groove 51 of triggering piece 31 both sides a microswitch 6 is installed respectively, the trigger end of microswitch 6 is towards triggering piece 31.Two microswitch 6 warning devices that are connected to later in parallel.The form of warning device can have multiple, no longer is described in detail at this.
If the trigger end return strength of microswitch 6 is smaller,, can also and triggers at microswitch 6 return spring 7 is installed between the piece 31 in order to make its fine return.
During normal the use, original key is injected in the keyhole at core power transmission shaft 4 centers, the pellet shot from a slingshot on the core power transmission shaft 4 forms same straight line in tapered end mobile 3.Directly unblank driver 2 of core power transmission shaft 4 is opened or is locked, and tapered end mobile 3 can not follow core power transmission shaft 4 and rotates, and can not trigger microswitch 6 and report to the police.
When using other key or unlocking tool to use to exceed the power of normally unblanking when twisting tapered end by force, the state that still misplaces of the pellet shot from a slingshot between core power transmission shaft 4 and the tapered end mobile 3.So tapered end mobile 3 will follow core power transmission shaft 4 and rotate.Tapered end mobile 3 triggers microswitch 6 when rotating and causes warning.When stopping to tapered end twisting destruction.The return spring 7 that is installed in spacing collar 5 both sides is with core power transmission shaft 4 homings.
