Abstract
The utility model discloses a blade lock head, comprising an outer lock shell, a middle liner inside the outer lock shell, a lock liner and a key inside the middle liner, wherein the lock liner is provided with a plurality of groups of blade tanks which are provided with blades; blade springs are arranged on the blades; the lock liner is internally provided with a key chamber; one or two sides of the lock liner are provided with lock pin tanks; lock pins are arranged in the lock pin tanks; one or two sides of the blades are provided with blade tank pits corresponding to the lock pins. When the lock is on, the lock pin ends can be inserted into the corresponding blade tank pits; and outer lock shell and middle liner are internally provided with a plurality of groups of locking mechanisms which are matched with the lock pins. The lock liner can rotate at 360 degrees in the middle liner; as the middle liner is blocked by the lock ball, the middle liner cannot rotate in the outer lock shell, and leads the lock head not to be opened while the lock liner can rotate, thereby preventing the lock core from being damaged due to twisting stress of external force and avoiding the technical opening by skeleton key or other objects.
Description
Technical field
The utility model relates to a kind of tapered end.
Background technology
At present, traditional machinery page or leaf sheet lock core probably is divided into two-layer, and promptly outer lock shell and lock gall are provided with a page film trap in the lock gall, in the page or leaf film trap a page sheet are installed, and are provided with spring eye in the page or leaf film trap, and leaf spring is arranged in the spring eye, and a page sheet chamber is arranged in the outer lock shell.When inserting corresponding key, will move along key setting height at leaf spring effect nextpage sheet, it is deviate from from page or leaf sheet chamber, be positioned at lock housing and lock core interface, lock core can rotate with respect to lock housing, realizes the unlatching of tapered end; Under lock-out state, each group page or leaf sheet partly enters in page sheet chamber under the leaf spring effect, and contact surface and lock core are not overlapped with the interface of lock housing, stops the rotation of lock core with respect to lock housing.Because the latch-up structure of such tapered end is simple, wrong-unlocking rate is higher, makes the safety of tapered end not high, can not effectively prevent to adopt master key or other object to carry out technical unlocking; And tapered end is under lock-out state, and lock core only depends on a page sheet to stop its relative lock housing rotation, when tool using is turned round by force it, can make page sheet occur axial rift, modification along lock core with lock interface place, thereby reach the purpose of unblanking.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of wrong-unlocking rate low and can prevent that external force from turning on the Mortise lock that opens by force.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of page of sheet idle-run lock head, comprise outer lock shell, be installed in the middle cover courage in the outer lock shell, lock gall and key in being installed in the cover courage, described lock gall is provided with some groups of page or leaf film traps, in the page or leaf film trap a page sheet is installed, on the page or leaf sheet leaf spring is installed, be provided with the key chamber in the lock gall, the one or both sides that it is characterized in that described lock gall are provided with the lock pin groove, in the lock pin groove lock pin is installed, the one or both sides of page or leaf sheet are provided with the page or leaf film trap hole corresponding with lock pin, under opening, the lock pin end can be inserted in the corresponding page or leaf film trap hole, in outer lock shell and the middle cover courage the some groups of locking mechanisms that cooperate with lock pin is installed.
Above-mentioned locking mechanism comprises envelope pearl, spring, flat pearl and lock pearl.
Page or leaf film trap of the present utility model hole can be " V " type or " U " type or semi-circular, and correspondingly an end of lock pin can adopt " V " type or " U " type or semi-circular shape.
As the utility model improvement of the technical scheme, middle cover courage is provided with positioning pit, is provided with locating hole in the outer lock shell, is equipped with in the locating hole pearl is installed.
As the utility model further improvement in the technical proposal, be provided with card slot in the middle cover courage, be provided with draw-in groove in the lock gall, the card pin is installed in described card slot and the draw-in groove.
On the cover courage jump ring is installed in above-mentioned.
Described page or leaf sheet is provided with a spoon groove, and is positioned at the spoon groove shape difference of the page or leaf sheet of lock gall diverse location.
The beneficial effects of the utility model are: the utility model is when lock-out state, each page sheet moves down under the leaf spring effect, make lock pin, lock pearl remain on lock gall and middle cover courage tangent line place mutually, this moment, lock gall can be done 360 degree rotations arbitrarily in middle cover courage, middle cover courage is owing to lock stopping of pearl, the cover courage can not be rotated in outer lock shell, make tapered end be in the rotatable and state that can not open of lock gall, damage lock core thereby can prevent to turn round by force, and can reach and prevent to adopt master key or other object to carry out the effect of technical unlocking because of external force.
