A key for a blade lock and a blade lock core matched with the key

Abstract

The invention discloses a key for a blade lock, comprising: a key handle and a key blade, the key blade includes two side surfaces and two flat end surfaces between the two side surfaces, two curved grooves are respectively arranged on the two flat end surfaces, It is characterized in that the two side walls of each curved groove are provided with reference positioning points of locking teeth. Compared with the prior art, the present invention provides reference positioning points for locking teeth on both side walls of the curved groove, and the locking teeth abut against the left or right side walls of the curved groove, effectively reducing the contact between the locking teeth and the right side of the curved groove. The matching tolerance of the curved groove is convenient for processing and the lock has good reliability. The present invention also provides a blade lock cylinder matched with the above key.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a key for a blade lock and a blade lock core matched with the key. Background technique [0002] A lock is a fastener that is placed on an openable object and opened with a key or a password. Common locks can be divided into blade locks, pin locks and combination locks of blade locks and pin locks. From the perspective of technology itself, the blade lock is the lock with the highest performance in preventing key mutual opening and technical opening. [0003] In order to improve the anti-theft performance of the blade lock, people have designed various anti-theft blade lock cylinders. The blade lock cylinder with lock pins is one of them, and usually includes a lock outer tank, a lock inner tank rotatably arranged in the lock outer tank, Number plate and lock pin. A number of slots are arranged parallel to the axial direction and perpendicular to the axis on the lock liner, and ...

Problems solved by technology

[0004] Compared with the combination of traditional pin locks and leaf locks and pin locks, although this leaf lock has better encryption, its number plate usually only has one reference point, and there is a risk of mutual opening and technical opening

Especially when the number of slots is small (less than six), some unscrupulous elements can still open the lock by moving the number to the appropriate position on both sides with special tools, and the safety factor still needs to be further improved.
