Abstract

The invention discloses a key and a lock cylinder. The key comprises a key bar and a key grip, wherein the key bar consists of a round bar sleeve, a bar core and a key piece with bits; the bar core is positioned in the bar sleeve; the key piece is provided with skewed slots, is arranged in the through groove of the bar sleeve, and is matched with the pin arranged on the bar core through the skewed slots; the bar sleeve is in clearance fit with the key grip axially; the bar core is fixed on the key grip; and a bar sleeve return spring is arranged between the bar sleeve and the key grip. The lock cylinder matched with the key comprises a lockhole, a dead bolt hole vertical to the lock hole, and a dead bolt arranged in the dead bolt hole, wherein the head of the dead bolt is positioned in the dead bolt hole. When the key is not in use, the bits are positioned in the bar sleeve, when the key is in use, the bits extend out, the dead bolt is not in the lockhole of the lock cylinder, the unlocking tool can not act on the lock cylinder to pry up the lock. The lock with the lock cylinder can prevent the lock from being pried and has better safety.

Description

A kind of key and lock core

Technical field

The invention belongs to lockset, particularly relate to a kind of key and lock core.

Background technology

Existing key can be divided into sheet bar type, half-moon-shaped and round bar type substantially according to its spoon rod-shape, and their common feature is the surface that tartar all is located at spoon bar, utilizes the realization that matches of pellet shot from a slingshot in the lockhole of tartar and lock core on the spoon bar when unblanking.The lock core lockhole shape supporting with these keys also is divided into rectangle, semilune and circle.Because the head of pellet shot from a slingshot extend in the lockhole in the lock core, therefore can tool using insertion lockhole be pried open by lock, most of picking locks stealing cases all are to belong to this situation in the society.

Summary of the invention

Technical problem to be solved by this invention is that prior art is improved, and a kind of key and lock core are provided, and to prevent carrying out picking lock by lockhole, improves the safety of lockset.

The technical solution adopted for the present invention to solve the technical problems is:

Key case spatula bar of the present invention and the shank of the key, the spoon bar by circular pin cover, bar core, have tartar the spoon sheet form, have through slot on the described bar jacket wall, the bar core is positioned at the bar cover, and the spoon sheet is provided with skewed slot, and the spoon sheet is arranged in the through slot of bar cover, the spoon sheet matches with pin on being located at the bar core by the skewed slot on it, the bar cover cooperates in axial activity with the shank of the key, and the bar core is fixed on the shank of the key, is provided with bar cover return spring between bar cover and the shank of the key.

Key of the present invention can also overlap external surface at bar one circle boss is set, and the front end that overlaps at bar is provided for the stops to the axial stop bit of spoon sheet simultaneously.

The present invention and the supporting lock core of described key comprise lockhole, the pellet shot from a slingshot hole vertical with lockhole, the pellet shot from a slingshot in the pellet shot from a slingshot hole, and the head of described pellet shot from a slingshot is positioned at the pellet shot from a slingshot hole.

Lock core of the present invention also can be provided with a circle concave station in the entrance of lockhole, matches to overlap lip-deep boss with described key bar.

The invention has the beneficial effects as follows: because behind key and the lock core employing said structure, the spoon bar of key is the circular pin cover, and the tartar of spoon on the sheet is positioned at the bar cover, and the pellet shot from a slingshot on the lock core is located in the pellet shot from a slingshot hole and do not stretch in the lockhole, no ridge in the lockhole like this, keep one cylindric.When with the instrument picking lock, no matter which kind of shape it adopts, and because of no fulcrum, can only can rotate and can't apply active force to lock core at lockhole behind the insertion lockhole, and lock core is played a protective role.When unblanking, only need the shank of the key is pressed forward, under the effect of bar core, the spoon sheet will be outwards outstanding from the bar cover, and the tartar on the spoon sheet stretches into to be made in pellet shot from a slingshot in the pellet shot from a slingshot hole lock is opened.The lock core tool supporting with key of the present invention can thoroughly solve the not problem of pick-proof of existing lock core, and good safety is arranged.

Further specify technical scheme of the present invention below in conjunction with accompanying drawing.

The specific embodiment

Embodiment 1

See Fig. 1, Fig. 2, key case spatula bar of the present invention and the shank of the key 6, the spoon bar is by circular pin cover 4, bar core 8, the spoon sheet 2 that has tartar 1 is formed, described bar overlaps and has through slot 3 on 4 walls, bar core 8 is positioned at bar cover 4, bar core 8 upper edge axis have the mounting groove 9 of perforation, spoon sheet 2 is located in the mounting groove 9 on the bar core 8, and spoon sheet 2 places in the through slot 3 of bar cover 4, spoon sheet 2 is provided with the skewed slot 11 of two perforations, and spoon sheet 2 matches with pin 10 on being located at bar core 8 by the skewed slot on it 11, and bar cover 4 cooperates in axial activity with the shank of the key 6, bar core 8 is fixed on the shank of the key 6 by steady pin 7, is being provided with bar cover return spring 5 on the bar core 8 between bar cover 4 and the shank of the key 6.

See Fig. 3, the lock core 12 that the present invention and described key are supporting, comprise the lockhole 16 that do not connect on the lock core 12, the pellet shot from a slingshot hole 14 vertical, the pellet shot from a slingshot 13 in the pellet shot from a slingshot hole 14 with lockhole 16, the lower end in pellet shot from a slingshot hole 14 is provided with reducing 15, and reducing 15 places that the head of pellet shot from a slingshot 13 is positioned at pellet shot from a slingshot hole 14 do not stretch into lockhole 16.

Lock core 12 also can adopt structure as shown in Figure 5, and its pellet shot from a slingshot 13 is provided with raised line 19 and matches with groove 18 on 14 walls of pellet shot from a slingshot hole, and the end 20 of groove 18 makes the head of pellet shot from a slingshot 13 be positioned at pellet shot from a slingshot hole 14 and do not stretch into lockhole.

Operating principle:

As shown in Figure 4, after key spoon bar inserts the lockhole of lock core, the bottom 17 of lockhole 16 is with spoon sheet 2 stop bits, with the shank of the key 6 ejection forward, bar core 8 acts on spoon sheet 2 by the pin on it 10 makes spoon sheet 2 interior protruding from bar cover 4, simultaneously key makes the pellet shot from a slingshot hole that the tartar 1 on spoon sheet 2 is aimed on the lock core, and this moment, the spoon sheet 2 continued outwards motion, and the tartar 1 on the spoon sheet 2 stretches into to be made in pellet shot from a slingshot 13 lock is opened in the pellet shot from a slingshot hole.The reverse operating key can be closed lock.When lock cut out, because of lockhole is a rounded cylindrical, if want to use the way picking lock of picklock with the insertion lockhole, picklock can only dally in lockhole because of no fulcrum, can not act on lock core, can't destroy lock core lock is pried open.

Embodiment 2

For the lock core of lockhole for connecting, as shown in Figure 6, key of the present invention can overlap 4 external surfaces at bar one circle boss 21 is set, and is provided for stops 23 to spoon sheet 2 axial stop bits at the front end of bar cover 4 simultaneously.Corresponding, the boss 21 corresponding concave stations 22 on a circle and the key bar cover 4 are set in the entrance of lock core lockhole 16.All the other are with embodiment 1
