Abstract
The utility model relates to a key of a burglar-proof door lock, whose structure comprises a body, wherein a plurality of tooth tables which are used for matching with marbles inside a lock core are arranged on the body, the tooth tables are arranged on the body in the length direction, and a locating slot is further arranged on the body, a curved groove is arranged on the body and is arranged on the opposite surface of the tooth tables, and the end portion of the curved slot, which is arranged on the body, is provided with a V-shaped open end. The arranged curved slot is matched with an anti-removing mechanism which is arranged in the lock core, and during the inserting and removing process of the key, the curved slot can enable relative components which are in the anti-removing mechanism to act, which is beneficial to improve the anti-removing function of the lock core.
Description
Technical field
The utility model relates to the key on a kind of safe-guard door lock.
Background technology
Key is used for the unlatching to safe-guard door lock, have the plurality of teeth platform of arranging along its length above it, the height of tooth platform on key body differs, and after key is inserted in the lock core, promptly can realize the rotation of lock core after having differential pellet shot from a slingshot in the tooth platform that these just differ and the lock core and cooperating.The theftproof performance of safe-guard door lock is mainly reflected in lock core antitheft, this simple anti-theft lock that constitutes by the stage differential style pellet shot from a slingshot, and its anti-poor-performing of dialling, the burglar can utilize the instrument of stirring with sensation lock core to be pushed aside.On the other hand, also need to be provided with locating slot on the key what have, it be used for lock core in the keyhole set positioning strip cooperate plug that can Key.But existing locating slot generally is arranged on the position of key axis, and locating slot is positioned at the dorsal part of above-mentioned tooth platform, and they are in in the longitudinal section.Because the setting of locating slot, in order not allow the depression between the tooth platform penetrate key body, differential between each tooth platform will be seldom, and be corresponding, and differential between each pellet shot from a slingshot also can be very little, and it is convenient that very little differential pellet shot from a slingshot also seems when utilizing instrument to stir.Therefore, because the set position of described locating slot makes lock core prevent dialling weak effect.
The utility model content
The purpose of this utility model: a kind of Key for anti-theft door lock that can be used with the anti-lock core that to dial performance good is provided.
The purpose of this utility model can realize by following technical proposal: a kind of Key for anti-theft door lock, comprise body, on body, have be used for lock core in the plurality of teeth platform that matches of pellet shot from a slingshot, the tooth platform is provided with on the length direction of body, also has locating slot on the body, described body is provided with a curved groove, and curved groove is on the opposite face of tooth platform, and curved groove has a V-arrangement openend in the end of body.
In this Key for anti-theft door lock, described curved groove is arranged in the bilateral symmetry of body axis.
In this Key for anti-theft door lock, described locating slot is two, and they are positioned on the dual-side of body length direction.
In this Key for anti-theft door lock, described body is provided with open-work, and open-work and tooth platform are on same straight line.
Compared with prior art, the beneficial effects of the utility model are:
On key body, be provided with curved groove, it can be used for lock core on the set anti-mechanism of dialling match, in the process that the lock core interpolation pulls key, the anti-mechanism of dialling can realize release or locking between lock core and tapered end, can increase the anti-group function of lock core.Curved groove on key body for curve trend, it not on the key body trend of tooth platform setting be provided with, this can not have influence on differential between the tooth platform, the pellet shot from a slingshot in the lock core is differential to have assurance.On key body, be provided with open-work, can in lock core, be provided with the anti-pellet shot from a slingshot of dialling, in the time of in key inserts lock core, this open-work can be passed in anti-end of dialling pellet shot from a slingshot, key can not have compressing to anti-end of dialling pellet shot from a slingshot, the anti-length of dialling pellet shot from a slingshot can equal the degree of depth in pellet shot from a slingshot hole on the lock core and the thickness sum of keyhole, prevents that group pellet shot from a slingshot can stop utilization to stir instrument other pellet shot from a slingshot is stirred, and helps to guarantee the anti-function of dialling of lock core.
Description of drawings
Fig. 1 is the front view of this theftproof lock key.
Fig. 2 is along the A-A sectional view among Fig. 1.
The specific embodiment
The specific embodiment of this Key for anti-theft door lock is seen Fig. 1, shown in Figure 2.
The structure of this Key for anti-theft door lock comprises key body 1, is provided with plurality of teeth platform 6 on body 1, and these tooth platforms 6 arrange that on the length direction of body 1 they point-blank.
The dorsal part of tooth platform 6 is provided with the curved groove 3 of curve extension on body 1, and curved groove 3 has V-shaped opening 5 in the end of body 1.When key was inserted in the lock core, the parts that will slide relatively in curved groove 3 in the lock core can more successfully enter in the curved groove 3 under the effect of opening 5.
Curved groove 3 is a symmetrical structure, promptly is that it is arranged in the axis of body 1 bilateral symmetry.If the associated components that slides in curved groove 3 is a plurality of, then can be at the inboard of lock core and the parts of arranged outside same structure, only their directions on lock core are opposite, and this helps to reduce number of components and parts on the lock core, has made things convenient for to produce and management.
On body 1, also be provided with an open-work 4, open-work 4 all is on the same straight line with all tooth platform 6, when key inserts in the lock core, open-work 4 can be passed in the end of the anti-group pellet shot from a slingshot that length in the lock core is consistent with the thickness sum of the degree of depth in pellet shot from a slingshot hole and keyhole, key can not oppressed anti-end of dialling pellet shot from a slingshot, when key was inserted in the lock core, the anti-pellet shot from a slingshot of dialling can not hinder lock core freely rotating in tapered end, and anti-group pellet shot from a slingshot can effectively increase the anti-function of dialling of lock core.
On the dual-side of body 1, also be provided with two locating slots 2, locating slot 2 be used for lock core in the keyhole set positioning strip match, help the plug of key.Locating slot 2 is positioned on the dual-side of body 1, staggers mutually in they and the position of tooth platform 6 on body 1, and the difference of height that this can not have influence between the tooth platform helps to guarantee the extreme difference between the pellet shot from a slingshot in the lock core.
