Abstract

The utility model relates to a cipher lock with an alarm and a theft-proof functions. The utility model is characterized in that the upper side of a lock core is sheathed with a groovy wheel and a spline wheel 2, an alarm switch 11 is arranged on a lock cover 16 which is corresponding to the groovy wheel 13, and a dialing wheel 3 is sheathed on the spline wheel and a handle. When the numerical code which is composed of the dialing wheel and a scale fixed plate 10 is uniform with the cipher number, a door can be opened. When the dialed numerical code is uniform with the cipher part, the lock is locked automatically, a knock pin 12 on the alarm switch falls into the groove of the groovy wheel, and an alarm conducts alarming. The utility model collects the functions of the theft protection, the alarm and the automatic lock into one body, has the free performance for giving the cipher, has the disposable performance for the cipher selection of opening the door, and has the advantages of safe operation and no key.

Description

The crypto-alarm theftproof lock

The utility model relates to a kind of lockset, especially the crypto-alarm theftproof lock.

In existing lockset, no matter be mechanical lock, electronic lock, or coded lock, do not have locked voluntarily function, more can not integrate password, warning and locked voluntarily.Disclose a kind of " safety cabinet case coded lock " as Chinese patent 9323658 5.X,, groped through repeatedly checking the number one by one though it has password, easily decoded, because locked warning device is not set, thereby this lock uses still dangerous reliable.

The purpose of this utility model provides a kind of password, warning, locked crypto-alarm theftproof lock voluntarily of integrating.It can not only send warning in locked, and safe and reliable.

The purpose of this utility model is achieved in that in the coded lock that comprises lock core, lock cover, scale fixed head, fixed head, handle, increases spline wheel, dialing wheel, sheave and alarm switch.Its structural feature is: 1. boss and alignment pin are arranged on the lock core, and one of lock core is connected with handle, and one is passed scale fixed head, lock cover and fixed head; 2. between handle and lock cover, be set with the spline wheel, the two ends of spline wheel are set with baffle plate, baffle plate contacts with the spline wheel through the top spring, lean on screw on the spline wheel, outer ring at the spline wheel is set with dialing wheel, the character cut in bas-relief number is carved with on the surface, outer ring of dialing wheel, has spring catch to withstand the spline gear teeth by same direction on the inner ring, at spline wheel inner ring small boss is arranged; 3. be set with sheave on the inner lock core of lock cover, sheave is connected with fixed head through spring, on the lock cover of sheave correspondence is whole alarm switch is arranged, and the ejector pin of alarm switch contacts with sheave; 4. alarm switch is connected with alarm outside the lock through lead.

The utility model is installed on when last, and its scale fixed head is fixed on the external surface of door, and fixed head is fixed on the inner surface of door, and lock core is connected with indoor built-in lock dead bolt in the prior art.

The utility model is setting code when installing, and the scale fixed head is fixing number, and dialing wheel is for rotating number.After password setting was good, in the time of need opening door, direction rotary dialing wheel got final product when pressing along pin.When the number on scale fixed head and the dialing wheel (comprising the dialing wheel on the handle) is that the password that sets is when counting, boss on the lock core and baffle plate center shrinkage pool match, lock core rotates and laterally moves with handle, this moment, the ejector pin of alarm switch contacted with the sheave crossbeam, do not carry out warning, boss is arranged especially as key on the preceding top of lock core,, door can be opened the tongue switching of built-in lock in the room.When rotating dialing wheel, when its number conforms to the password fractional part, lock core has trace to rotate with handle and moves, alignment pin on the lock core is screwed in the gap of small boss of spline wheel inner ring, the ejector pin of alarm switch breaks away from the sheave crossbeam and falls in the groove of sheave, be that alarm is opened, send chimes of doom.Thereby realize locked voluntarily and warning function, reach and prevent that the thief from deciphering the purpose of stealing key.If will eliminate warning, door must be opened, alarm switch is taken off, change new alarm switch.If want Change Password, only need lock core is pulled out half, get final product by rotating counterclockwise the dialing wheel setting code.

Adopt such scheme, can realize locked voluntarily and warning function, have password setting with sex change, door-opening password is selected disposable; Can avoid using listening, door lock is opened in the method deciphering of armrest sense; Cancelled key, the worry that has disappeared and brought by key.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is A-A sectional view of Fig. 1;

Fig. 4 is warning circuit figure of the present utility model.

Fig. 1, Fig. 4 are embodiment of the present utility model.

In the accompanying drawings, the utility model mainly is made up of lock core 1, spline wheel 2, dialing wheel 3, baffle plate 4, scale fixed head 10, alarm switch 11, alarm 18, sheave 13, spring 14, fixed head 15, lock cover 16, handle 17, its architectural feature is: 1. boss 5 and alignment pin 6 are arranged on the lock core 1,1 one of lock cores are connected with handle 17, and one is passed scale fixed head 10, lock cover 16 and fixed head 15; 2. between handle 17 and lock cover 16, be set with three spline wheels 2, the two ends of spline wheel 2 are set with baffle plate 4, baffle plate 4 contacts with spline wheel 2 through top spring 8, be screwed on spline wheel 2, outer ring at spline wheel 2 is set with dialing wheel 3, the character cut in bas-relief number is carved with on the surface, outer ring of dialing wheel 3, and the spring catch 9 on the inner ring withstands spline by same direction and takes turns 2 teeth, and taking turns 2 inner rings at spline has and protrudingly close 7 for a short time; 3. be set with sheave 13 on the lock core 1 of lock cover 16 inside, sheave 13 is connected with fixed head 15 through spring 14, and covering at the lock of sheave 13 correspondences has alarm switch 11 on 16 walls, and the ejector pin 12 of alarm switch 11 contacts with sheave 13; 4. alarm switch 11 is connected with the alarm 18 of lock body outside through lead.

The utility model is installed on after door goes up, and when stirring the number of 4 dialing wheels (dialing wheel on three spline wheels and the handle), if dialing wheel 3 conforms to set password with the number of scale fixed head 10 compositions, then can open; If part conforms to, then can send warning and be automatically locked simultaneously; If not identical, then handle and lock core only rotate and can not move, and door is not opened.
