Abstract

The invention relates to a back locking mechanism of a tapered ned, which consists of a lock body (1), a lock cylinder (2) and a key hole (3). One or more profiled marbles (4) are positioned in the lock cylinder (2); the profiled marble (4) is provided with a sidewall gap (6) and a side marble (7) corresponding to the sidewall gap (6); and a slotted hole (8) corresponding to the side marble (7) is positioned on the lock body (1). The back locking mechanism is characterized in that: a spring (9) or a magnet (10) with mutual reaction formation is positioned in the lock body (1) or the lock cylinder (2) and corresponds to the side marbles (7). The cross section of the slotted hole (8) on the lock body (1) is apparently larger than the caudal cross section of the side marble (7); both cross sections are provided with sharp angles (11); and the afterbody of the side marble (7) can be provided with a transverse gap (12). The mechanism achieves the functions of unlocking and locking by pushing the side marbles (7) in or out through the spring (9) or the magnet (10) which is provided with the mutual reaction formation. The mechanism of the invention can avoid the situation that when a strong twisting force is exerted on, the side marbles (7) of the pin tumbler lock are forced into the lock cylinder by the curved hole of the lock body (1), thereby being opened by the burglar; in the way, the mechanism can effectively prevent the lock from being opened technically or devastatingly, thereby improving the burglar-proof function of the pin tumbler lock.

Description

Tapered end lock office
One, technical field
The present invention relates to a kind of cylinder lock, particularly a kind of cylinder lock of side switch locking is widely used in the occasion use that theftproof performance is had relatively high expectations.
Two, technical background
The general theftproof of present cylinder lock is poor, the cylinder lock that the side switch locking preferably of a kind of theftproof performance is wherein arranged, patent No. ZL98251737.8, title is a kind of special-shaped cylinder lock, mainly comprise lock body, lock core and keyhole, the special-shaped marble of spring and band control flume is housed in the pellet shot from a slingshot hole in the lock core, the groove vertical with the pellet shot from a slingshot hole arranged in the lock core, mobilizable control strip and control spring are housed in the groove, and the position of corresponding groove has arcuate socket on lock body.This is locked in and stirred and during strong torsion by unlocking tool, and control strip can be pressed into by the arcuate socket on the lock body in the lock core and by pirate of the open.
Three, summary of the invention
The objective of the invention is to be turned round the deficiency of dialling and opening by unlocking tool in order to overcome special-shaped cylinder lock, a kind of office of locking is provided, be by spring with mutual acting in opposition or magnet, drive the side pellet shot from a slingshot and push or withdraw from the effect of playing the open and close lock, this lock can effectively prevent to be turned round by unlocking tool and dial out.
The technical solution adopted for the present invention to solve the technical problems is, comprise lock body, lock core and keyhole, one or more special-shaped marble is arranged in the lock core, special-shaped marble has the sidewall breach, to the side pellet shot from a slingshot should be arranged, the slotted eye corresponding with the side pellet shot from a slingshot arranged on the lock body, be primarily characterized in that: corresponding to the side pellet shot from a slingshot spring or the magnet with mutual acting in opposition is arranged in lock body or the lock core, the slotted eye cross section of lock body is obviously greater than the afterbody cross section of side pellet shot from a slingshot, two cross sections all have wedge angle, and the afterbody of side pellet shot from a slingshot can have horizontal breach.Its structure can also be done following several improvement, and promptly supplementary features are: 1. a row or two rejection type pellets shot from a slingshot are arranged in the lock core, or the cover core is arranged between lock body and the lock core, the side pellet shot from a slingshot is made of head and afterbody two parts.2. the special-shaped marble profile is cylindrical, and the sidewall breach is a cannelure, and the profile of side pellet shot from a slingshot is bar shaped, flat, sheet shape or comb teeth shape.3. the special-shaped marble profile is that head is the cylindrical of wedge shape, and the sidewall breach is the hole, and the profile of side pellet shot from a slingshot is bar shaped, flat, sheet shape or comb teeth shape.4. the special-shaped marble profile is arc or annular, and its sidewall breach is a groove, and the profile of side pellet shot from a slingshot is bar shaped, flat, sheet shape or comb teeth shape.5. the special-shaped marble profile is bar shaped or trisquare shape, and its sidewall breach is a groove, and the profile of side pellet shot from a slingshot is bar shaped, flat, sheet shape or comb teeth shape.6. the special-shaped marble profile is a spill or back-shaped, and its sidewall breach is a groove, and the profile of side pellet shot from a slingshot is bar shaped, flat, sheet shape or comb teeth shape.7. special-shaped marble is the composite pellet that is formed by two or more unit constructions, and its sidewall breach is a groove, and the profile of side pellet shot from a slingshot is bar shaped, flat, sheet shape or comb teeth shape.
The invention has the beneficial effects as follows, this structure adopts the spring of mutual acting in opposition or magnet drive side pellet shot from a slingshot to push or withdraw from, play the effect of open and close lock, the side pellet shot from a slingshot of having avoided cylinder lock is suppressed in the lock core by the arcuate socket on the lock body when being subjected to strong torsion and by pirate of the open, can effectively stop technical and destructiveness to be unblanked, thereby improve the theftproof performance of cylinder lock.
