Abstract
The utility model relates to a theft-proof alarm cylinder lock. On the basis of the existing cylinder lock, the external end of a cylinder on an external layer is provided with an insulating rod extending from a lock core sleeve, the insulating rod is provided with one or two conducting rings, and both sides of the insulating rod are respectively provided with a metal spring piece contacted with the insulating rod; after connected in series or in parallel, the metal spring pieces on both sides of each insulating rod are used as two output terminals of a sensor. The utility model has the advantages of simple and reasonable structure, strong key recognition ability, convenient utilization, safety, etc., and can be connected with input terminals of alarm signals of various alarms or theft-proof devices to form a plurality of theft-proof devices or theft-proof alarms.
Description
The utility model relates to a kind of burglar alarm cylinder lock that can be connected with the alarm signal input of burglar alarm and can discern and in time send signal rapidly when inserting key, belongs to a kind of alarming lock.
Anti-theft alarm lock mainly comprises cylinder lock that can output alarm signal and can send the alarm of signals such as sound, light, electricity or cut off alarms compositions such as oil circuit, wherein, can prevent non-bitting from smashing out cylinder lock and send the performance crux particularly of the lock of alarm signal to alarm or alarm, but that existing alarming lock is discerned the ability of non-bitting is relatively poor.
The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, to design a kind of good burglar alarm cylinder lock of performance of discerning key.
Technical measures of the present utility model are to comprise lock core, the lock core cover, the internal layer pellet shot from a slingshot, outer pellet shot from a slingshot, marble spring, on the basis of the existing cylinder lock that single face key or multiaspect key or magnetic key are formed, the outer end of outer pellet shot from a slingshot respectively is connected to an insulating bar stretches out the lock core cover, a pressure spring plate and one deck insulating slab are equipped with in the lock core cover outside, appropriate location on the insulating bar is provided with a circle or two circle conducting rings, the insulating bar both sides have the metal clips that is in contact with it to be contained on the insulating slab respectively, and the metal clips series connection of each insulating bar both sides or two outputs of series connection back parallel connection earlier are connected with the alarm signal input of burglar alarm.
Accompanying drawing 1 is the structural representation of an embodiment of the present utility model;
Accompanying drawing 2 is structural representations of another embodiment of the present utility model.
Referring to accompanying drawing, 1 in the accompanying drawing and 9 is signal output parts of burglar alarm cylinder lock, the 2nd, and the outer ring conducting ring, the 3rd, insulating bar, the 4th, inner ring conducting ring, the 5th, metal clips, the 6th, insulating slab, the 7th, pressure spring plate, the 8th, outer cover, the 10th, marble spring, 11 lock core covers, the 12nd, outer pellet shot from a slingshot, the 13rd, internal layer pellet shot from a slingshot, the 14th, key, the 15th, lock core.Wherein, insulating bar 3 is connected on the outer pellet shot from a slingshot 12 and stretches out lock core cover 11, be respectively equipped with on the insulating bar 3 inner ring conducting ring 2 or outer ring conducting ring 4 (as shown in Figure 2) or in, outer two circle conducting rings 2 and 4 (as shown in Figure 1), the outside of lock core cover 11 is equipped with the marble spring 10 that one deck pressure spring plate 7 will be sleeved on the insulating bar 3 and is press-fited in the pellet shot from a slingshot hole, insulating slab 6 is contained on the pressure spring plate 7, the both sides of insulating bar 3 have the metal clips 5 that is in contact with it to be contained on the insulating slab 6 respectively, in being equipped with on each insulating bar shown in the accompanying drawing 1, outer two circle conducting rings, two outputs 1 after metal clips 5 series connection of each insulating bar 3 both sides and 9 are the alarm signal output ends of alarming lock.It avoids last available outer cover 8 protections destroying.Shown in the accompanying drawing 2 be have in the insulating bar be provided with inner ring conducting ring 2, what have is provided with outer ring conducting ring 4, and its annexation is that two outputs 1 in parallel again after will being provided with the metal clips series connection of inner ring conducting ring both sides respectively earlier and will being provided with the metal clips series connection of conducting ring both sides, outer ring and 9 are the alarm signal output ends of alarming lock.During design, what can decide according to the needs of lock the figure place of pellet shot from a slingshot, and the cylinder lock of forming for multiaspect key such as two-sided or three or four sides or magnetic key can also can all be reequiped arranging pellet shot from a slingshot and reequip wherein arranging pellet shot from a slingshot more.The pellet shot from a slingshot of repacking is many more, and the ability of identification key is strong more.In order accurately to discern valid key, when the set positions of the inner ring conducting ring 4 on the insulating bar 3 is set in key 14 dial-outs with metal clips 5 position contacting, outer ring conducting ring 2 when key 14 inserts and metal clips 5 position contacting.During use, the signal output part 1 of this lock is connected with the alarm signal input of can luminous and sounding type or sending various burglar alarms such as radio signal or alarm respectively with 9.When valid key is inserted lock core, crown can be in the time range of very short delayed alarm changes the contact position of each insulating bar 3 and metal clips 5 into inner ring conducting ring 4 by outer ring conducting ring 2, thus can be under the situation of not reporting to the police rotational lock core 15 and normally unblanking.When non-valid key or other foreign matter insertion lock core, as long as there wherein have one or more crown or the different outer ring conducting rings that make internal layer pellet shot from a slingshot 13 just in time outer pellet shot from a slingshot 12 not pushed back the lock core cover or will contact with metal clips with valid key of foreign matter height to change time of inner ring conducting ring into to be long or when taking out insulating bar, the signal output part of this lock all can become disconnection and output alarm signal makes alarm equipment alarm or alarm is moved by conducting.
Theft-proof alarming cylinder lock of the present utility model has simple and reasonable, the strong and use of the ability of identification key The advantage such as convenient and safe can be used as the alarm signal input of theft-proof sensor and various alarm or antitheft apparatus Connect, form multiple alarm or burglar alarm.
