Abstract
Disclosed is an electromagnetic cipher safety lock, mainly comprising a lock tongue. The utility model is characterized in that the rear part of the lock tongue is combined with the electromagnetic core of an electromagnet into a whole, and a number disc with keystrokes is connected with the electromagnet by a power switch circuit. The utility model has the advantages of favorable sealing performance, reliable theft-proof performance, simple structure, easy manufacture and low cost.
Description
The utility model relates to a kind of cipher lock, relates to a kind of electromagnetic type cipher lock specifically.
Traditional all kinds of locksets mostly are with key operated cylinder lock, and due to its structure, the theftproof performance of this type of lock is relatively poor.For addressing this problem, occurred some theftproofs electronic type coded lock preferably recently, but this class lock is higher because of its manufacturing cost, and fails to obtain large-area applying.
The purpose of this utility model provides a kind of safety performance good with regard to being to overcome above-mentioned weak point of the prior art, electromagnetic type cipher lock simple in structure.
The purpose of this utility model can adopt following measure to realize:
The dead bolt rear portion of electromagnetic type cipher lock of the present utility model and the electromagnetic core of electromagnet combine; The figure disc that has button links together by power switch circuit and electromagnet.
Figure disc in the utility model is provided with 15 numerical keys, device for fusing, resetkey, power key and warning, power supply, number indicator lamp; Contact in its power switch circuit is that adjustable password is compiled the accent sheet, and the setting of this structure is to reset password at any time for the ease of the user.
Advantage of the present utility model is not only have good confidentiality, and theftproof also has advantage simple in structure, easy to manufacture, that cost is low simultaneously reliably.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the front view of the utility model tapered end part.
Fig. 2 is the front view of figure disc.
Fig. 3 is power switch circuit figure.
Fig. 4 is another embodiment of power switch circuit figure.
The utility model is done with detailed description below with reference to embodiment (accompanying drawing):
As shown in Figure 1, electromagnetic type cipher lock of the present utility model is made up of tapered end (1), lock body shell (2) and dead bolt (3); The dead bolt rear portion combines by the electromagnetic core (4) of attachment screw and electromagnet; The figure disc (7) that has button links together by the terminal plate (6) on power switch circuit and the electromagnet (5).
As shown in Figure 2, the figure disc in the utility model is provided with 15 numerical keys (8), and device for fusing (14), resetkey (12), power key (10) and warning, power supply, number indicator lamp (13), (11), (9).
Fig. 3 is a kind of embodiment of the utility model power switch circuit, the elementary direct and civil power of transformer ZB joins in this circuit, low-tension current after the transformation is sent into contact (15) (adjustable password is compiled and transferred sheet) after an end of transformer secondary output is by rectifies, when pressing numerical key in proper order by prior programmed password figure, each adjustable password is compiled transferred sheet (15) closure, when entire circuit was connected, electromagnet DT conducting adhesive can be opened door.If when pressing button (or any key pushes the wrong) not according to the program of establishment in advance, ac circuit is by electric capacity c or directly form path, all will make and protect alert device DD and form ac circuit and report to the police, and only press resetkey this moment and upspring in closed contact to remove warning.Adjustable password in the circuit is compiled and transferred the setting of sheet (15) is to reset password at any time for the ease of the user.
Fig. 4 is a kind of embodiment of the utility model power switch circuit, and T is a bouncer in this circuit, and D1 is a fuse, when pressing numerical key in proper order, make each contact (15) closure, when entire circuit is connected by prior programmed password figure, electromagnet DT conducting adhesive can be opened door.If when pressing button (or any key pushes the wrong) not according to the program of establishment in advance, the capital makes the ac circuit short circuit, forming big electric current blows a fuse, this moment bouncer T closure, alarm circuit is connected reports to the police, only open device for fusing, change insurance bouncer is opened, can stop reporting to the police.
Claims (3)
1, a kind of electromagnetic type cipher lock, it mainly comprises dead bolt (3), it is characterized in that: the electromagnetic core (4) of the rear portion of dead bolt (3) and electromagnet combines; The figure disc (7) that has button links together by power switch circuit and electromagnet (5).
2, electromagnetic type cipher lock according to claim 1, it is characterized in that: figure disc (7) is provided with 15 numerical keys (8), device for fusing (14), resetkey (12), power key (10) and warning, power supply, number indicator lamp (13), (11), (9).
