Abstract
A night lock and a key of the night lock comprise a lock case, a lock cylinder and a key. A key groove is formed in the lock cylinder, two bead grooves which are perpendicular to the key groove are formed in the lock cylinder, a plurality of plugging beads and ladder-shaped beads which are in staggered arrangement are arranged in the bead grooves, the plugging beads extend to the key groove, bits which are matched with the plugging beads and the ladder-shaped beads are arranged on the key, and the plugging beads which are matched with the bits are of through-hole structure. According to the night lock and the key of the night lock, a plurality of plugging beads are arranged in the lock cylinder key groove, the plugging beads extend to the key groove, and the plugging beads which are matched with the bits are of through-hole structure, accordingly the plugging beads extend into the key hole completely, and seal the front face of the key groove completely. Besides, the staggered arrangement of the plugging beads ensures that an unlocking tool is hard to bypass blocking of the plugging beads, meanwhile the key groove is made to be deep and narrow, the ladder-shaped beads are hidden in the hollow of the key groove, the unlocking tool can not move the ladder-shaped beads, and thus anti-theft effect is good.
Description
Technical field
The utility model relates to a kind of cylinder lock head and key thereof, specifically a kind of supporting cylinder lock head and key that is applicable to the products such as security door, interior door, safety cabinet, automobile and motorcycle.
Background technology
The tapered end of commonly using in the market mainly contains two kinds of anti-technology unlocking modes: a kind of S of being groove tapered end, principle are crooked by the S shape of key, hinder unlocking tool and stir pellet, and another kind is to realize the anti-function of dialling by various Special-shaped marbles.S groove tapered end is for the unlocking tool of today, technical difficulty far from; Although Special-shaped marble structure unlocking difficulty has increased, fault rate also increases on year-on-year basis.
Summary of the invention
Technical problem to be solved in the utility model is the above-mentioned shortcoming that exists for existing tapered end, provide a kind of good anti-theft effect cylinder lock head and key thereof.
The utility model solves the problems of the technologies described above the technical scheme that adopts:
A kind of cylinder lock head and key thereof, include lock housing, lock core and key, described lock core is provided with key, described lock core is provided with and the vertically arranged bullet groove of described key, be provided with shutoff pellet and the trapezoidal pellet of some interlaced arrangement in described bullet groove, described shutoff pellet extends to key, the described tartar that coordinates with shutoff pellet and trapezoidal pellet that is provided with on the key, and the described tartar that coordinates with the shutoff pellet is through-hole structure.
Described bullet groove is two rows, is arranged in parallel.
Compared with prior art, the utility model: 1, be furnished with many shutoff pellets in the core key, the bullet of shutoff pellet extends in key, and the key tooth flower that coordinates with the shutoff pellet is through-hole structure, illustrate that the shutoff pellet extends to key fully, the key front is sealed fully, also have shutoff pellet interlaced arrangement, unlocking tool is difficult to get around stopping of shutoff pellet; 2, key is done deeply done narrowly, trapezoidal pellet is hidden in the key recess, and unlocking tool can't push trapezoidal pellet, good anti-theft effect from the side.
