Abstract

The utility model relates to an anti-theft lock cylinder and a key, which are formed by a lock case movable toggling fork, pins, a lock core hole, a lock cylinder core, a key hole and a key. The lock cylinder core is assembled inside the lock core hole, pin holes are arranged on the lock cylinder core, each pin hole is provided with a core pin which is a straight-through pin, and length of the straight-through pins is sum of length of the pin holes and thickness of the key. Length of each pin of the lock cylinder core is a fixed value, and one value is set as a number which is a key code. The anti-theft lock cylinder and a key have the advantages of capability of preventing various technical unlock tools, drilling and tamper resistance, simple manufacturing and low cost.

Description

A kind of anti-theft lock and key

Technical field

The utility model relates to a kind of lockset, especially relates to a kind of anti-theft lock and key.

Background technology

In the improvement that all has aspect pellet shot from a slingshot arrangement and the Key structure in various degree, but still there is the mutual opening rate height in various locks in the market and copys easier defective.Most of anti-theft locks and key, the plane of its lock core or arc surface are the initial sum end of atom, and atom does not have straight-through pearl, its defective is, cause the one's share of expenses for a joint undertaking of committing theft to invade from the side with unlocking tool, the instrument of being beneficial to refers to directly invade and bump is unblanked, and its theftproof performance is relatively poor; Key does not have password, increases trouble when falling key.

Summary of the invention

The utility model anti-theft lock goes purpose just to be a kind of anti-theft lock and key are provided, and has to prevent various skilled unlocking instruments, anti-drilling pick-proof, making advantage simple, with low cost.

The technical scheme that the utility model provides for achieving the above object comprises, by the lock housing lock core, keyhole, movable shift fork and lock heart hole are formed, and wherein the lock core heart is assemblied in the heart hole, be provided with 7 atom holes in its lock core in the heart, each atom hole all has a heart atom to be straight-through pearl, and the straight-through pearl length thickness sum that is atom hole length and key, and each atomic length of lock core is a fixed value, a value is made as a numeral, and its numeral is a key cipher.

Described keyhole is made as the M type, and the hole length direction is the high direction unanimity in heart cylinder center, vertical keyhole plane, atom hole or arc surface and tangent.

The plane of described key body or arc surface are the flower flank of tooth, and the pond groove face is a reverse side.Every key all has a perforation.

Described each atom all has a fixed value, and its value is made as password.Straight-through pearl is a code name.

Advantage of the present utility model is:

When 1, lock core was closed, unlocking tool can't be from the impouring of atom adjacency, and any instrument enters from the front can be stirred straight-through pearl and can't open.

2,, but, have the loss and the difficulty that can prevent that key from bringing in no key bitting because this lock core key has password.

3, consistent novel anti-theft lock core has anti-various technology unlockings, and Prying-resistant and drilling-resistant is made simply, and cost hangs down multiple advantage.

The specific embodiment

Embodiment, as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6 is made up of lock housing 1 movable shift fork 2, atom 3, lock heart hole 4, lock core heart 5, keyhole 6 and key 7.Wherein lock core heart 5 is assemblied in the heart hole 4, and its lock core heart 5 is provided with 7 atom holes, and each atom hole all has a heart atom 3 to be straight-through pearl, and straight-through pearl length is the thickness sum of atom hole length and key 7.Each atomic length of lock core heart is a fixed value, and a value is made as a number, and its number is key cipher.

Described keyhole 6 is made as the M type, and the hole length direction is the high direction unanimity in heart cylinder center, vertical keyhole 6 planes, atom hole or arc surface and tangent.

Described key 4 planes or arc surface are the flower flank of tooth 8, and pond groove face 9 is a reverse side.Every key all has a perforation.

Described each atom 3 all has a fixed value, and its value is made as password.Straight-through pearl is a code name.
