Description

T type key

Technical field: the utility model relates to a kind of T type key.

Background technology: present key is generally cross-key or plane spoon, when can only inserting lockhole by a direction, cross-key just can unblank, when unblanking night, direction of insertion to key is difficult to identification, normal wrong plug direction consequently is difficult to extract, even makes a mess of lock core, in addition, the mutual opening rate of cross-key lock is higher, and theftproof performance is low relatively.And but spoon normal tow sides in plane insert or extract lockhole, so that make a mess of lock core, moreover the mutual opening rate of plane lock is higher.Therefore, be necessary to be further improved.

Summary of the invention:

For addressing the above problem, the utility model purpose is to provide a kind of T type key of a kind of comprehensive cross-key and plane spoon feature.

The utility model is achieved in that a kind of T type key, be complementary with the T type keyhole of lock core, comprise the shank of the key and key insertion portion, wherein the key insertion portion comprises the lath of a level, it is characterized in that being convexly equipped with the vertical rib that to insert lock core keyhole, have heel teeth on the lower surface of described vertical rib in the bottom surface of binding piece.

Have on the bottom surface of the binding piece of above-mentioned T type key and the corresponding tartar of lock core marble.

Be equipped with on the end face of the binding piece of above-mentioned T type key and the corresponding magnetic pin of lock core marble.

The both sides of the binding piece of above-mentioned T type key have heel teeth.

The utility model is the T type key of cross-key and plane spoon combination, and mutual opening rate is low, can prevent joining key.Because keyhole is the T type, can better confirm direction of insertion, stops the possibility of multidirectional insertion key; Again because the tartar that has on the bottom surface of key binding piece, and tartar or magnetic pin on the end face of key binding piece, can be complementary with the pellet shot from a slingshot of lock core, stopped multidirectional possibility of extracting key.
