Abstract
The utility model discloses a lock core, and particularly relates to a lock core of a tenon and mortise joint structure. The lock core consists of a lock core plug and a lock core shell, wherein plug beads are arranged in the lock core plug; shell beads are arranged in the lock core shell; the inner ends of the plug beads and the shell beads are butted to form one-piece lock beads; the lock core is provided with a plurality of one-piece lock beads; the outer ends of the shell beads are provided with springs; the lock core is characterized in that: the inner ends of the plug beads are provided with mortises, and the inner ends of the shell beads are provided with tenons, so that the butting of the plug beads and the shell beads forms tenon and mortise joint; the waist of each plug bead is provided with a step, so that the plug bead is clamped on the inner edge of the plug core plug through the plug bead; the other end of each plug bead extends out of the lock core plug, the end part of the plug bead is provided with a taper corner; a notch is formed on the taper corner; the notches of the plurality of plug beads are different from one another; and the sections of the mortises and the tenons can be transverse H-shaped, triangular, oblong and trapezoidal. In the utility model, the connection relation of the shell beads and the plug beads is designed into an interleaving tenon and mortise joint state, so that the performance of anti-theft, anti-pry and anti-damage opening is greatly improved.
Description
Technical field
The utility model is a kind of lock core, particularly a kind of mortise structure lock core.
Background technology
Existing lock core; All be Spring cylinder lock core, the plug pearl of Spring cylinder lock core and the contact form of shell pearl contact with point for point or face contact with face, and point contacts or defective that face contacts with face is that the contact site is and point or face and face contact with each other together with putting; The dynamics of its contact is very small and weak; Under external force, be easy to pried open, so theftproof performance is not good enough.
Summary of the invention
The purpose of the utility model is in order to overcome the existing not good enough defective of Spring cylinder lock core theftproof performance, invents a kind ofly will fill in the mortise structure lock core that pearl and contacting of shell pearl are made the joggle form into.
The purpose of the utility model is to realize by following form: said mortise structure lock core; Form by lock core plug and lock core shell, be provided with the plug pearl in the lock core plug, be provided with the shell pearl in the lock core shell; The inner of plug pearl and shell pearl connects and constitutes the Body linked lock pearl, and lock core is provided with a plurality of Body linked lock pearls; The outer end of shell pearl is provided with spring, it is characterized in that: the inner of plug pearl is provided with tongue-and-groove, and the inner of shell pearl is provided with tenon, thereby makes the butt joint of plug pearl and shell pearl form joggle; The waist of plug pearl is provided with a step, through step the plug pearl is stuck on the interior rib of lock core plug; The other end of plug pearl stretches out from the lock core plug, and its end is provided with a cone angle, and cone angle is provided with notch, and the notch on a plurality of plug pearl is different.
That the section of said tongue-and-groove and tenon comprises is I-shaped, triangle, rectangle, trapezoidal.
The plug pearl of said mortise structure and shell pearl comprise single pearl and the two pearl structures of primary and secondary.
The good effect of the utility model is following: the utility model is designed to staggered joggle state to the annexation of shell pearl and plug pearl, so promoted the performance that antitheft, pick-proof, anti-destructive are opened greatly.

The specific embodiment
Shown in Figure 3 like Fig. 1 Fig. 2, said mortise structure lock core is made up of lock core plug 1 and lock core shell 2, is provided with plug pearl 3 in the lock core plug 1, is provided with shell pearl 4 in the lock core shell 2, and the inner of plug pearl 3 and shell pearl 4 connects and constitutes the Body linked lock pearl, and lock core is provided with a plurality of Body linked lock pearls; The outer end of shell pearl 4 is provided with spring 5, it is characterized in that: the inner of plug pearl 3 is provided with tongue-and-groove 6, and the inner of shell pearl 4 is provided with tenon 7, thereby makes the butt joint of plug pearl 3 and shell pearl 4 form joggle; The waist of plug pearl 3 is provided with a step 8, through step 8 plug pearl 3 is stuck on the interior rib 9 of lock core plug 1; The other end of plug pearl 3 stretches out from lock core plug 1, and its end is provided with a cone angle 10, and cone angle is provided with notch 11, and the notch 11 on a plurality of plug pearl 3 is different.
That the section of said tongue-and-groove 6 and tenon 7 comprises is I-shaped, triangle, rectangle, trapezoidal.
The plug pearl 3 and the shell pearl 4 of said mortise structure comprises single pearl and the two pearl structures of primary and secondary.
When key inserted lock core fully, key bit on the key connected airtight with the notch of plug pearl end, forces the Body linked lock pearl to rotate; The joggle position and the key shaped that make plug pearl and shell pearl are at an angle of 90; At this moment key just can rotate, and along with the rotation of key, the plug pearl will break away from the shell pearl; Lock mechanism in the releasing, lock just is opened; When key went back to original position and extracts out, key bit on the key was just from forcing the Body linked lock pearl to be turned back to original position in the other direction, and on original position, joggle position and the key of plug pearl and shell pearl are not 90 ° of angles, so lock is just locked.This moment, the Body linked lock pearl can only be up and down, thereby the lock core plug is fixed, and sets up lock mechanism thus, and lock core can't be opened.Because joggle Body linked lock pearl closely connects as one, and blocks the lock core plug, institute so that lock core have quite high anti-ly take off, prevent choosing, tamper-resistant function.
