Description

A kind of have a radially idle-run lock pin of clutch component

Technical field:

A kind of have radially that the idle-run lock pin of clutch component belongs to the mechanical lock field, is applicable to prevent that the bad person from unblanking with non-former key or violence.

Background technology:

The kind of mechanical lock is a lot, probably can be divided into cylinder lock, the lock of blade lock and magnetic class, the structure of mechanical lock is mainly by lock housing, lock body, lock core, dead bolt and page or leaf sheet pellet shot from a slingshot (or pellet shot from a slingshot or magnetic grain) lock housing are entangled lock body, lock body entangles lock core, lock core can rotate, movable pellet shot from a slingshot is housed in the hole of lock body and lock core correspondence, be locked in when using (closure state), the pellet shot from a slingshot of lock body enters the pellet shot from a slingshot hole of lock core, lock core is fixed can not rotate, dead bolt is just inactive yet, unblank, inject keyhole with key, the tartar on the spoon can promote the pellet shot from a slingshot of lock core, the pellet shot from a slingshot of lock body and the pellet shot from a slingshot contact surface of lock core are overlapped with the contact surface of lock body and lock core just, so reverse key energy rotational lock core, lock core drives dead bolt and leaves fixing lock housing, lock is opened.

But the safety of mechanical lock also has problem, not only can use skilled unlocking, also can unblank by force, as: available non-original key inserts lock core, reverses lock core by force and destroys pellet shot from a slingshot, also can borrow some instruments, destroy the retaining element of lock core or lock body, powerfully take out lock body or lock core and unblank.At present, also there are some locks to adopt the structure of idle-run lock pins to prevent technical or violence nature is unblanked, as Chinese patent application number: 200710035991.7 (titles: a kind of idle-run lock head); 200910043795.3 (titles: a kind of clutch structure of idle-run lock pin) and for example.In order to realize idle running, section lock core (the back segment lock core connects dead bolt) before and after adopting, before and after the connection of section lock core be by the lock pin on the control back segment lock core along lock core shaft to the structure that enters or withdraw from the leading portion lock core, a realization front and back section lock core rotates simultaneously or has only the leading portion lock core to rotate, but not original key can only make the leading portion Lock cylinder idling, the back segment lock core can not change, so non-original key is not driven lock.But the clutch structure of these lockpin-types (axially) exists the lock pin rapid wear, be difficult for resetting, thereby functional reliability is relatively poor; In addition, for make lock pin along lock core shaft to entering or withdraw from, need to increase parts such as slide block, for pellet shot from a slingshot is installed, need to increase lock tube etc., thereby increased cost and volume.

The utility model content:

What the utility model proposes a kind ofly has a radially idle-run lock pin of clutch component, its objective is to prevent that non-original key or violence from reversing the malfeasance that lock core is unblanked, and the clutch structure of simplifying idle-run lock pin, improve the reliability of clutch.

The technical solution adopted in the utility model is: adopting radially, clutch component makes Lock cylinder idling.

A kind of have a radially idle-run lock pin of clutch component, comprises lock housing, lock body, front and back lock core, dead bolt and page or leaf sheet pellet shot from a slingshot, and front and back lock core is enclosed within the lock body and can rotates; It is characterized in that front and back lock core passes through radially clutch component interlock, described radially clutch component comprises axial depression bar, spring, spring and ball; Axially on the depression bar groove fixing spring bar is arranged, the surperficial porose spring and the ball of being installed with of axial depression bar, ball is pressed in by the spring in the hole on the inner headed face of lock body, and preceding lock core and rear lock core have axial groove and axial depression bar movingly, and the axial groove of preceding lock core communicates with a page sheet pellet shot from a slingshot hole on the preceding lock core.

Above-mentioned a kind of radially idle-run lock pin of clutch component that has, described radially clutch component has two to be distributed on the front and back lock core symmetrically.

Above-mentioned a kind of radially idle-run lock pin of clutch component that has has annular arc shaped groove to cooperate with ball on the inner headed face of described lock body.

Above-described a kind of radially idle-run lock pin of clutch component that has, described rear lock core has cylindrical step, has on the step and axial depression bar axial groove movingly.

The utility model is owing to adopted the clutch component of axial depression bar, and this member moves in radial direction, makes front and back lock core clutch, and its required part is few and simple in structure, and axially the depression bar combination is firm, not fragile, reliable operation.

Among the figure: lock body 1, preceding lock core 2, spring 3, ball 4, axial depression bar 5, spring 6, page or leaf sheet pellet shot from a slingshot 7, preceding lock core axial groove 8, rear lock core axial groove 9, rear lock core 10, inserted bar of lock hole 11, keyhole 12, step 13, groove 14, inserted bar of lock 15, page or leaf sheet pellet shot from a slingshot hole 16, annular arc shaped groove 17.

The specific embodiment

Now demonstrate this programme, Fig. 1-6 has shown structure of the present utility model, and by lock body 1, preceding lock core 2, rear lock core 10 and page or leaf sheet pellet shot from a slingshot 7, front and back lock core also can rotate in lock body; Radially clutch component interlock is passed through in the interlock of front and back lock core, and described radially clutch component comprises axial depression bar 5, spring 6, spring 3 and ball 4; Axially on the depression bar groove 14 fixing spring bars (Fig. 1) are arranged, the axial surperficial porose spring 3 and the ball 4 of being installed with of depression bar, ball are pressed in by the spring in the hole on the annular arc shaped groove 17 of inner headed face of lock body (Fig. 2).This routine rear lock core outside cylinder has step 13, have on the step rear lock core axial groove 9 and axial depression bar 5 movingly, preceding lock core axial groove 8 and axial depression bar 5 movingly, before lock core have hole 16 and page or leaf sheet pellet shot from a slingshot 7 movingly, this Kong Yuqian lock core axial groove and spoon groove 12 communicate, and rear lock core 10 ends have inserted bar of lock hole 11 pin inserted links 15.

Operating principle of the present utility model is, unblank if enter keyhole 12 with non-former spoon, page or leaf sheet pellet shot from a slingshot 7 does not have change, the still axial depression bar 5 of jack-up in the position in page or leaf sheet pellet shot from a slingshot hole 16, ball 4 is pressed to lock body 1 annular camber groove face 17, axially depression bar can not fall into rear lock core axial groove 9, at this moment, reverses key, lock core changes before can only making, and rear lock core 10 and inserted bar of lock 15 do not rotate, so inserted bar of lock 15 can not be stirred dead bolt and unblank.If unblank with former spoon, the shift in position of page or leaf sheet pellet shot from a slingshot makes axial depression bar enter rear lock core axial groove 9 downwards, reverses key, and at this moment, front and back lock core all rotates, and inserted link 15 is also along with rotating and stirring dead bolt and unblank.
