CN2501769Y - Theft-proof lock for electric switch of motorcycle - Google Patents

Abstract

An antitheft lock of the motorcycle electric simulation switch adopts a method of indirect driving between a key and a lock biliary, i.e. the key drives the cassette lock blade which drives the lock biliary to rotate. When the lock blade group matches the key teeth, the external detent in the lock biliary can be retracted to the small groove on the inside wall within the lock biliary so that the key keeps rotating until opening the lock gate and the electric simulation switch. When the key does not mesh with the cassette lock blade group, the external detent can not enter into the small groove on the inside wall within the lock biliary and the lock biliary can not rotate so that a stronger rotation will lead to a total breaking of the internal clip leaving only an empty circle in the lock blade group, thereby any tool only being able to rotate in vain in the lock biliary so as to guard against theft effectively.

Description

Motor bike electric switch anti-theft column lock

The utility model relates to motor bike electric switch anti-theft column lock.

Traditional motor bike electric door lock uses the design of locking plate resistance formula cuboid lockhole, adopt the mode of through-coupling lock gall to drive lock grid and switch, when meeting destructiveness and unblanking, because the cuboid lockhole is inserted by steel disc easily, rotating lock gall energetically can make locking plate fracture, make lock gall rotate immediately, thereby drive the lock grid, cause electric switch to open.

The purpose of this utility model is to provide the motor bike electric door lock of the good indirect drive of a kind of theftproof performance.

The purpose of this utility model can realize like this: a kind of motor bike electric switch anti-theft column lock, comprise switch, lock body and the key that matches with lock body, described key inserts the lock gall that can drive in the lock body in the lock body and rotates, and cause unlatching lock grid and switch to be switched on, it is characterized in that: described lock gall comprises some interior identical circular lock sheet groups of external diameter, this group locking plate is offered an identical little groove along external diameter, shim and cassette locking plate by interspersed arrangement are mutually formed, this shim outer circumferentially is provided with identical small lugs, this small lugs is identical with the gap width that the lock gall sidewall is offered, this cassette locking plate is interior, periphery upwards respectively extends the small lugs of an identical or different angular separation width, described lock gall comprises that also one is arranged near the lock sheet groups, with the corresponding outer lock pin of the little groove of locking plate, there is a groove to take on the madial wall of this lock gall for outer lock pin, the center of lock gall is provided with for the corresponding center circular shaft that inserts of key, the external diameter of this lock sheet groups is identical with the lock gall internal diameter, and described key is for cooperating the hollow circular cylinder of cassette locking plate combination.

Because the utility model adopts the described indirect drive lock gall of technique scheme mode to drive lock grid and switch, if the key that matches with the combination of cassette locking plate inserts lock gall, pulling locking plate rotates, outer lock pin promptly snaps in the little groove of lock sheet groups, key can continue to drive lock gall and rotate, outer lock pin is promptly taken in the little groove of lock gall inwall, and lock gall can be rotated further to opening lock grid and switch; If key is not meshed with the combination of cassette locking plate, outer lock pin can not enter in the little groove of lock gall inwall, and lock gall is not rotatable, if through rotating energetically, the interior card on the cassette locking plate can all cut off again, only surplus empty circle in the lock sheet groups, any instrument all can only dally in lock gall, thereby reaches antitheft purpose.

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

Fig. 1 is the assembly decomposing schematic representation of embodiment 1 of the present utility model.

This embodiment 1 described motor bike electric switch anti-theft column lock comprises switch plug 18, lock body 1, lock grid 2, lock gall 3, locking closure 16, the outer bayonet lock 19 of circle strip, the cylindrical key 17 of hollow, in the lock gall 3 there be by being the circular identical lock sheet groups of interior external diameter generally device, this lock sheet groups is by cassette locking plate 4,6,8,10,12,14 and shim 5,7,9,11,13 compartment of terrains rearrange, the outer identical small lugs of angular separation 20 that circumferentially is provided with of shim wherein, this small lugs 20 is identical with breach 21 width that lock gall 3 sidewalls are offered, the cassette locking plate is interior, periphery upwards respectively extends the small lugs of an identical or different angular separation width, offer identical little groove 22 simultaneously in the outer of lock sheet groups, in the lock gall 3 also the lock sheet groups outer be provided with the little groove 22 of lock sheet groups corresponding outside lock pin 19, there is a groove to take on the madial wall of lock gall 3 for outer lock pin 19, the center of lock gall 3 is provided with for the key 17 corresponding center circular shafts 23 that insert, the external diameter of this lock sheet groups is identical with the internal diameter of lock gall 3, key 17 is for cooperating the hollow circular cylinder of cassette locking plate combination, pick-proof locking closure 15 devices are between lock sheet groups and trim, to withstand lock sheet groups.

The assembly method of this motor bike electric switch anti-theft column lock is as follows: will lock the lock grid groove that grid 2 are put into lock body 1 earlier, again lock gall 3 is inserted in the lock body 1, to put into lock gall 3 with cassette locking plate, shim that key 17 coincide successively then, and alignment is inserted in the wild card cotter way for outer bayonet lock 19, put into pick-proof locking closure 15 at last, stamp rivet, trim 16 is covered.
