Description
Affiliated technical field
The utility model relates to a kind of mechanical lock, particularly a kind of lock head device.
Background technology
Lock in the market is various, various in style, but the lock of sample whatsoever, with regard to its substantive structure, can roughly be divided into two big classes: a class is to combine by pearl under the last pearl, pearl is single circular beads with following pearl on it, and the change in size of following pearl is carried out permutation and combination, and how many mutual opening rates of how many decision locks of its permutation and combination is.The mutual opening rate of this conventional lock is very high, usually the mutual opening rate of lock is in two one thousandths, and the more important thing is that this conventional lock is easy to be opened it in a short period of time with unlocking tool (as screwdriver, special iron wire or other special tool etc.) by the robber, make it lose theftproof performance.Two classes are atom locks popular on the existing market, this lockset also is the circular beads structure, just it locks some difference part with descending pearl traditionally, promptly improved with interior pressure or external pressure side bumper sheet locking principle, when this class lock has just been put on market, also obtained customer's approval, but service time is of a specified duration excessively, the robber is more and more familiar to this type of lock structure, and research is arranged deeply, finally also is not reach anti-theft effect, because the tartar conversion of atom lock also produces at the diverse location of circular beads, and circular beads with descend pearl lock the same traditionally, that leans on circular beads during unlatching moves up and down the locking edge catch, it is the most handy that this principle is unblanked to the robber.And the atom lock is single pearl structure owing to be subjected to its structural limitations usually entirely, so mutual opening rate is also than higher.
Summary of the invention
At the deficiencies in the prior art part, the purpose of this utility model provide a kind of safe, technology grind simply, for a long time durable, use lock head device easy and simple to handle.
For achieving the above object, the utility model adopts following technical scheme: a kind of lock head device, comprise the cylindrical shape mesochite in lock housing, the lock housing, the lock cylinder in the mesochite, the lock core external surface is provided with many cannelures, the plug face of cannelure position have one with the lock core side bumper film trap of lock core axially parallel, mesochite and lock housing corresponding position are respectively equipped with a mesochite side bumper film trap and a lock housing groove, and catch is on one side arranged in it; Be provided with an arc page or leaf sheet and a leaf spring in the cannelure, leaf spring one end props up the flange that page sheet outer arc is provided with, and the other end props up lock core; Each page sheet outer arc is provided with one page sheet groove, and each page sheet groove is in same straight line and the side bumper sheet can be in the lock core side bumper film trap when page or leaf sheet tooth portion and key tooth flower coincide.
The beneficial effects of the utility model are: be provided with an arc page or leaf sheet and a leaf spring by adopting in a side bumper sheet and every cannelure, leave core type page or leaf sheet in the realization structure is set, effectively reach anti-theft feature, safe, mill is durable for a long time, and technology is simple, uses easy and simple to handle.
