Description
Technical field:
The utility model relates to a kind of Shaped lock barrel, is used for door lock, belongs to the hardware ﹠ tools technical field.
Technical background:
Before the utility model was made, in prior art, the lock core tapered end was a monolithic, and it mainly is made up of tapered end, lock core, pellet shot from a slingshot, spring.Adopt row's pellet shot from a slingshot in the lock core, the different numbers of key only are 6000 variations, and easily by technical opening, key is replicated easily.
Technology contents:
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple in structure, compactness, rationally, and low cost of manufacture, key is difficult for being replicated, and can prevent the Shaped lock barrel of technical unlocking effectively.
Main solution of the present utility model is achieved in that
It mainly adopts lock core 2 to be installed in the tapered end 1, divides four rows to be shaped on 18 holes at lock core 2 circumference, and 36 pellet shot from a slingshot 4,3 and springs 5 up and down are housed in 18 holes altogether.
Description of drawings:
Fig. 1 is the utility model structural representation:
Fig. 2 is the utility model structure A-A sectional view:
