Abstract

The utility model discloses a theft-proof lock. The theft-proof lock comprises a lock beam and a lock body, wherein the middle part of the lock body is provided with a groove, two sides of the groove are respectively provided with a shaft hole, a lock shaft is arranged in the shaft holes, a password modification key is arranged on the lock shaft, a password key is arranged on the password modification key, and a lock cylinder is arranged at the bottom of one side of the lock body. The theft-proof lock has the advantages of attractive appearance, simple and reasonable structural design, double protection of the lock cylinder and the password and safe and reliable performance, and can be used as a perfect theft-proof lock and widely applied.

Description

Theftproof lock

Technical field

The utility model relates to a kind of lockset, relates in particular to a kind of theftproof lock.

Background technology

Raising along with expanding economy and people's living standard; Steal phenomenon also happens occasionally; Thereby the safety problem of property has also caused people's care more, but traditional lockset all is to lock with single lock core, because of its anti-theft effect simple in structure unsatisfactory; The robber in flagrant delict uses unlocking tool just can in a short period of time lock be opened, thereby can't effectively ensure property safety.

Summary of the invention

In order to overcome the deficiency of prior art, the utility model provides a kind of good looking appearance, structure design advantages of simple, lock core and password duplicate protection, safe and reliable theftproof lock.

The utility model solves the technical scheme that its technical problem adopted:

Theftproof lock comprises lock bridge and lock body, and the middle part of said lock body is provided with groove; The dual-side of groove is provided with axis hole, in the said axis hole lock shaft is installed, and password is installed on the lock shaft revises key; Said password is revised on the key cryptographic key is installed, and at a side bottom of said lock body lock core is installed also.

As the optimization of above-mentioned embodiment, said password is revised key and cryptographic key is the hollow circular cylinder that shape, size are complementary, and said cryptographic key is socketed in and is fixed together with screw after password is revised on the key; Said cryptographic key is several, is provided with from zero to nine totally ten numerals at the external surface of cryptographic key.

The beneficial effect of the utility model is: the utility model structure design is ingenious rationally; Middle part at said lock body is provided with groove; The dual-side of groove is provided with axis hole, in the said axis hole lock shaft is installed, and password is installed on the lock shaft revises key; Said password is revised on the key cryptographic key is installed, and at a side bottom of said lock body lock core is installed also; The utility model adopts lock core and password duplicate protection, and good anti-theft effect is safe and reliable, can be used as desirable lock extensive use.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the overall structure sketch map of the utility model;

Fig. 2 is the structural representation after the utility model removes cryptographic key;

Fig. 3 is the sketch map after the utility model removes cryptographic key and password modification key.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, theftproof lock comprises lock bridge 1 and lock body 2; The middle part of said lock body 2 is provided with groove 3; The dual-side of groove 3 is provided with axis hole 4, in the said axis hole 4 lock shaft 5 is installed, and password is installed on the lock shaft 5 revises key (6); Said password is revised on the key 6 cryptographic key 7 is installed, and at a side bottom of said lock body 2 lock core 8 is installed also.

As the optimization of above-mentioned embodiment, it is the hollow circular cylinder that shape, size are complementary with cryptographic key 7 that said password is revised key 6, and said cryptographic key 7 is socketed in and is fixed together with screw after password is revised on the key 6; Said cryptographic key 7 is several, is provided with from zero to nine totally ten numerals at the external surface of cryptographic key 7, and certainly as required, said numeral also can substitute with English alphabet.

The utility model structure design advantages of simple adopts lock core and password duplicate protection, when wanting to open lockset; Must be earlier with password position transfer to after could open lock core with key; If input password mistake also can't be opened lockset with original-pack key or with lock core sled evil idea, the utility model good looking appearance, good anti-theft effect, performance are safe and reliable; Thereby can be used as desirable lock extensive use, and can effectively ensure people's property safety.

In addition, the utility model is not limited to above-mentioned embodiment, needs only the technique effect that reaches the utility model with essentially identical means, all should belong to the protection domain of the utility model.
