Abstract
The utility model discloses a porous antitheft door lock sleeve. The porous antitheft door lock sleeve comprises a lock sleeve cover plate arranged on an indoor antitheft lock, wherein at least two lock holes which are the same as antitheft door lock holes are formed in the lock sleeve cover plate, one lock hole is a true hole, and the other hole is a trapping hole; a first alarm switch is arranged in the trapping hole; a second alarm switch is arranged on a mounting surface of the lock sleeve cover plate and the antitheft lock; and the first alarm switch and the second alarm switch are connected with an alarm loop. After the original door lock is provided with the novel practical door lock sleeve, an antitheft alarming function can be increased, and safety performance can be greatly improved. In addition, an alarm, an alarm lamp, a battery and the like are arranged in the inner side of a door, so that the parts are difficult to damage and are extremely convenient to mount and maintain. In general, the porous antitheft door lock sleeve has a simple principle and low cost, is convenient to manufacture and does not influence the normal use of the original door lock.
Description
Technical field
The utility model relates to a kind of security door lock tube that adopts a plurality of lockhole apparatus, it is contained in common door locks and can increase anti-theft feature.
Background technology
Current general door lock perhaps is easy to pried open by the robber no matter how ingenious design is, and perhaps price is very high.The security door manufacturing enterprise in the whole nation all is " mechanical anti-theft lock " standard of carrying out Ministry of Public Security's promulgation.This standard code, the protection level of lockset are divided into two of A, B, and the anti-technical unlocking time of A level theftproof lock, it was qualified to be greater than 1 minute; The anti-technical unlocking time of B level theftproof lock was qualified greater than 5 minutes.Obviously, the B level is locked in and is higher than A level lock on the anti-technical unlocking far away, is A level lock but the security door of selling in the market generally adopts.Because it is too high to install the lockset cost of special-shaped pellet shot from a slingshot additional, according to " security door safety specification " regulation, anti-theft door lock cylinder is necessary for the lock of non-single-row billiard structure.Under the ordering about of interests, some little factories do not add special-shaped pellet shot from a slingshot for practicing thrift cost, adopting, and the not high lockset of perhaps special-shaped pellet shot from a slingshot precision causes safe-guard door lock non-anti-theft, is easy to opened by the thief.Existing other safe-guard door lock also often has the false alarm or the untimely problem of reporting to the police, and burglary-resisting installation generally is placed in the lock outside, has both reminded the robber, makes equipment be prone to go to pot, and theftproof performance itself is also reliable inadequately.
Summary of the invention
The utility model technical problem to be solved is the deficiency to above-mentioned prior art, and a kind of porous type security door lock tube that collects non-destructive door lock and the warning of destructive door lock is provided.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of porous type security door lock tube; Comprise the lock tube cover plate that is installed on the interior theftproof lock, in described lock tube cover plate, be provided with at least two lockholes identical with the security door lockhole, one of them lockhole is true hole; All the other lockholes are the trap hole; In described trap hole, be provided with first alarm switch, on lock tube cover plate and theftproof lock installed surface, also be provided with second alarm switch, described first alarm switch is connected with alarm circuit with second alarm switch.
Be connected with warning light and alarm buzzer on the described alarm circuit.
Described first alarm switch comprises spring foil metal and fixing metal sheet, and described spring foil metal is arranged in the trap hole.
On original door lock, install after this utility model door lock cover, can increase anti-theft alarm function, greatly improve its security performance.In addition, alarm, alarm lamp, battery etc. all are installed in an inboard, neither subject to destroy very convenient again installation and maintenance.Generally speaking, this utility model principle is simple, easy to make, with low cost, and does not influence the normal use of original door lock, therefore is prone to accepted by the producers and consumers, will have good market prospects.
The beneficial effect of the utility model is: under the certain condition of existing door lock security performance; Through increasing the number of lockhole; Can improve the security performance of non-destructive door lock greatly, the probability of being pried open when supposing to adopt existing certain door lock is P, then adopt porous after; The probability that door lock is pried open under the situation of not touching alarm is P/n, and n is the lockhole number.Simultaneously, the utility model also is provided with alarm switch between theftproof lock and lock tube, in case destructive dismounting door lock occurs, then will inevitably make warning circuit work, starts alarm buzzer and warning light.The indoor design in trap hole can be tried one's best simply on the lock tube, as long as be as good as with true hole in appearance.Can significantly reduce workload and the material usage of making lock tube like this, thereby reduce cost, make consumers in general be more prone to accept.
