Three-point two-piece reverse security door lock cylinder of lock
The invention discloses a three-point two-piece reverse security door lock cylinder of a lock. The three-point two-piece reverse security door lock cylinder comprises a lock cylinder shell, a lock cylinder body, a plurality of insertion pieces and tension springs. The two sides of the inner side wall of the lock cylinder shell are each provided with a horizontal insertion piece protrusion groove. The multiple insertion pieces are arranged inside the lock cylinder body. The opposite sides of every two adjacent insertion pieces are each provided with a protrusion corresponding to the insertion piece protrusion grooves in the two sides. An insertion piece sliding pushing block is arranged inside a key insertion hole in each insertion piece. A stop piece groove corresponding to a lock key groove is further formed in each insertion piece. Each insertion piece is connected with the lock cylinder body through one tension spring, so that the insertion piece moves transversely inside the lock cylinder body and elastically resets through the tension spring. Due to the fact that the opposite sides of the every two adjacent insertion pieces are each provided with one protrusion corresponding to the insertion piece protrusion grooves in the two sides, after lock keys are added, three points inside the same vertical plane are used for unlocking, the opening difficulty of the lock cylinder is greatly increased, and then the safety of the security door lock is improved.
