Technical field

The utility model relates to a kind of coded lock, in particular to a kind of portable acousto-optic alarm cipher lock.

Background technique

Antitheft using the structure progress of simple mechanical, there are the corresponding relationships of volume (weight) and anti-theft capability.Individually Using the product of electronically, volume is reduced there is no apparent, and portability index does not also improve；And its antitheft line Cable is single structure, and antitheft principle is simple.Some is powered mode using dry cell or button cell, has not met now Use habit and its battery the outside for being mounted on locking conjunction, directly battery is removed, the function of lock can fail.Some Coded lock does not make full use of structural advantage, causes code wheel small, operating handle is poor.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of portable acousto-optic alarm cipher locks, solve portability Solve the problems, such as antitheft in such a way that light structure adds electric acousto-optic alarm with the opposed problem of anti-theft capability, cable is independent Multicore structure, antitheft not simple on-off detection, is related to multi-signal detection, power supply source is also designed to that USB is straight Rechargeable type is inserted, more meets environmental protection and the nowadays use habit of people, effectively solves deficiency in the prior art.

The utility model is achieved through the following technical solutions: a kind of portable acousto-optic alarm cipher lock, including the One lock head and the second lock head, the first lock head and the second lock head are locked slotting completion and are assembled, the first lock head and the Using a 4 core conducting wires connection between two lock heads, which is made of four mutual independent cores；

First lock head includes main part and live part, and the main part includes a main body cover, electricity Chi Xin, sound-light alarm component and PCBA mainboard, sound-light alarm component connection PCB A mainboard and by the chip control on PCBA mainboard System issues sound-light alarm information, and the charging interface of live part is installed on the outboard end of battery, which is one straight The structure for the formula of inserting, is incorporated in main body cover together；

The inner end of main body cover is provided with a trigger switch, and the outboard end of trigger switch is provided with a snubber elastomeric part, The contact of the protrusion of corresponding position is provided on second lock head of face trigger switch, the first lock head and the second lock head are mutual Trigger switch is contacted by contact when mutually assembling, and forms a signal；

Code wheel is provided on second lock head, code wheel includes code wheel outer ring and code wheel inner ring, code wheel outer ring suit In the outside of code wheel inner ring, the outboard end of code wheel inner ring and code wheel outer ring installs outer ring door sealing locking, outer ring door Using screw thread rotation assembly locking between the second lock head, contact is installed on the top position of outer ring door.

The wirerope that the every core is woven by more finer wires as a preferred technical solution, is set between core It is equipped with insulating layer, four core process are together.

The sound-light alarm component includes loudspeaker and LED light as a preferred technical solution, and loudspeaker is installed on master The back of body case, downward, LED light is installed on PCBA mainboard upper surface to vocal hole, and entire sound-light alarm component passes through battery Core power supply.
