Abstract
The utility model relates to a twist lock core. The utility model is characterized in that existing springs arranged straight are changed to the springs arranged spirally, a straight key wing trough used for the insertion of a key is changed to a spiral key wing trough, the straight key wing of the key is also changed into the spiral key wing, and spring particles are arranged, mixed and combined with one another in equidistance and unequal distance; the variation of the utility model is extremely large, the key is not easy to imitate and replicate, the theftproof ability of the utility model is strong, and the utility model is a novel lock core; the utility model can be widely used on various locksets such as gate locks, bicycle locks, padlocks, chain locks, etc.
Description
The utility model relates to a kind of lock core, especially relates to the lock core that a kind of pellet shot from a slingshot twist shape is arranged.
The pellet shot from a slingshot of present cylinder of spring lock is arranged as the equidistant arranged type of straight shape, though the combination of the different length by each pellet shot from a slingshot and have certain theftproof performance, the position of its pellet shot from a slingshot easily to be detected and easily by with other key runin and easy by hand or on the market existing bitting machine duplicate the deficiency of usurping.
The purpose of this utility model is to provide a kind of combined amount big, and repetitive rate is low, the lock core of transreplication and imitation not.
The purpose of this utility model be achieved in that feature of the present utility model be in the lock core keyhole spoon wing groove in the direction of the clock ecto-entad rotation make twist shape spoon wing groove and corresponding one by one with the twist shape installation site of pellet shot from a slingshot, the spoon wing of key also is processed into identical with the shape of spoon wing groove, distance between each pellet shot from a slingshot can equate also can be unequal, but the anglec of rotation of all spoon wing grooves in each lock core must be consistent, otherwise key can't insert and extract, during unlatching key is inwardly screwed in the direction of the clock, outwards screw out counter clockwise when extracting key, spoon wing groove can be one, immediate shipment one row's pellet shot from a slingshot, also can be many, pellet shot from a slingshot is arranged in immediate shipment more, and others are identical with existing cylinder of spring lock.
The utility model adopts the single row or multiple rows twist shape to arrange equidistantly or not equidistantly to arrange between pellet shot from a slingshot grain and the grain that to have the combination and variation amount big, and difficult imitated and duplicate, repetitive rate is low, and is difficult by other key runin, has stronger theftproof performance.
Fig. 1 is a side view of the present utility model.
Fig. 2 is a front view of the present utility model.
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
On lock core 7, have keyhole 16, is furnished with spoon wing groove 1 on the keyhole 16,2,3,4 grades one or more, each bar spoon wing groove is all by the smooth clockwise A that inwardly rotates a certain angle, B etc., the installation site 11 of each pellet shot from a slingshot of each bar, 12,13,14 grades are done rotary twist shape in the direction of the clock and are installed, distance D between the distance C homology functor 12 and 13 between the pellet shot from a slingshot 11 and 12 can be that equate or unequal, the anglec of rotation A of each pellet shot from a slingshot or B etc. must be identical, 5 be wherein one row pellet shot from a slingshot the position, 6,8 part positions for other two row's pellets shot from a slingshot, 9 only move step for lock core, 10 is the tag mark of key direction of insertion, and 15 is the pellet shot from a slingshot head.
