Super C type lock cylinder

Abstract

The invention provides a super C type lock cylinder and relates to the technical field of door locks. A locking blade is arranged on one side of a lock inner cylinder. When a key is inserted into thelock inner cylinder, the tooth portion of the key does not make contact with the locking blade, when the key is rotated, the tooth portion of the key pushes the locking blade to move, and the technical problem that in the prior art, in the unlocking process, the tooth portion of the key always influences the position of a spring or a sliding piece, and breaking is achieved through the technical unlocking method is solved. The device comprises the lock inner cylinder containing the key, a blade set arranged on the side, away from the tooth portion of the key, of the lock inner cylinder, a locking plate arranged perpendicular to the blade set, a transmission device connected with the locking plate and the lock inner cylinder, and a lock outer cylinder used for fixing the lock inner cylinderand the transmission device. The super C type lock cylinder is used in a door lock, when the key is inserted or drawn out, the key is away from the blade set, and therefore the problem that the limiting principle is perceived through some technical means, and the door lock is unlocked easily is avoided.

Description

technical field [0001] The invention relates to the technical field of door locks, in particular to a super C type lock cylinder. Background technique [0002] A door lock is, as the name implies, a device used to lock a door to prevent others from opening the door. There are many classifications of door locks, and the requirements for door locks are different in various occasions, but all kinds of door locks are generally based on the matching principle of marbles and keys, even the slide type principle of C-level super C-type lock cylinders is also the same. The principle is similar to that of the marbles. The position of the pins or slides is pushed by the different tooth shapes of the key. When all the pins or slides match the original designed opening position, the inner core and the outer core of the lock will not be affected by the pins or slides. On the contrary, if the key does not match the original design, the inner core will be restricted by the pins or slides a...

Problems solved by technology

[0003] The object of the present invention is to provide a super C type lock cylinder. By arranging the locking blade on one side of the lock inner core, the key tooth part does not contact the locking blade when the key is inserted into the lock inner core. When the key is rotated, the key tooth part Push the locking blade to move, which solves the technical problem in the prior art that the key tooth always affects the position of the pin or slide during the unlocking process, and can be cracked by technical unlocking
