Abstract

The utility model relates to the lock field, particularly a safe theft-proof lock, which comprises a lock body of which the interior is provided with a main lock core and a lock bolt extended into an outer lock body. The utility model has the characteristics that the interior of the lock body is also provided with an auxiliary lock core; the upper end of the lock body is provided with a gear box, and a pair of gears which are arranged in the gear box are engaged; the front end of a gear shaft a of a gear a is connected with the main lock core, and the rear end is connected with the lock bolt extended into the outer lock body; the front end of a gear shaft b of a gear b is connected with the auxiliary lock core, and the front end of gear shaft b of the gear b is connected with a rotary lock body sheathed on the auxiliary lock core; the main lock core is composed of a front and a rear two sections of the lock core. As the lock core adopts a main and an auxiliary double-lock core structure, the main and the auxiliary double lock cores are close, the main and the auxiliary double lock cores have the front and rear two section lock core structure and the gears which are engaged also have a conducting and constraining function, the utility model has the advantages of good theft-proof effect, high safety performance, etc.

Description

Safety anti-theft lock

Technical field

The utility model relates to the lock field, is a kind of safety anti-theft lock.

Background technology

Existing lock all is the monolock cored structure, for being engaged in lock Industry Personnel or robber, without this lock private key, uses general unlocking tool, and just can pry open lock within a short period of time, and therefore, anti-theft effect is poor, exists unsafe factor.

Summary of the invention

The purpose of this utility model is, prior art is improved, and a kind of safety anti-theft lock is provided.

The purpose of this utility model is realized by following technical scheme: a kind of safety anti-theft lock, it comprises lock body 19, be built-in with main lock core 2 at lock body 19, be provided with the dead bolt 10 that stretches in the outer lock body 9, its special character is, in lock body 19, also be equipped with and pay lock core 16, in the upper end of lock body 19 gear-box 7 is set, gear-box 7 built-in a pair of gear 6a, 12b are meshed, the gear shaft 5a front end of gear 6a is connected with main lock core 2, its rear end is connected with the dead bolt 10 that stretches into outer lock body 9, and the gear shaft 11b front end of gear 12b is connected with a pair lock core 16.The gear shaft 11b front end of gear 12b be placed on the rotational lock of paying on the lock core 16 15 and be connected.Described main lock core 2 is made up of forward and backward two-phase lock core 2a, 2b.

Safety anti-theft lock of the present utility model is with the phase-locked ratio of existing monolock core, and, pair twin-lock cored structure main owing to the lock core employing, and main, pair twin-lock core close proximity even use general unlocking tool to pry open single core, also can't be pried open twin-core; Also because main lock core has forward and backward two-phase lock cored structure, use general unlocking tool can only pry open the leading portion lock core, and prize less than the back segment lock core, the leading portion lock core is when lock body rotates, owing to fail to pry open the back segment lock core, the back segment lock core still can not rotate; Also have the conduction constraint effect owing to a pair of gear that is meshed again, so, the utlity model has good anti-theft effect, the security performance advantages of higher.

The specific embodiment

Utilize drawings and Examples that the utility model is further described below.

Embodiment 1: with reference to Fig. 1, this safety anti-theft lock is main, pair twin-lock core rotation lock, must use two keys just can unblank.It has lock housing 1, is installed with lock body 19 in lock housing 1.Be built-in with main lock core 2, pair lock core 16 that matches with it at lock body 19.In lock housing 1, the upper end that is positioned at lock body 19 is provided with gear-box 7.Gear-box 7 built-in a pair of gear 6a, 12b are meshed, and the gear shaft 5a front end of gear 6a is connected with main lock core 2, and its rear end is connected with the dead bolt 10 that stretches into outer lock body 9, and the gear shaft 11b front end of gear 12b is connected with a pair lock core 16.Lock body 19 and main, pay in the

lock core

2,16 and be equipped with several pellets shot from a slingshot 4, main, pay the spacer pin 3 of

lock core

2,16 by separately and be loaded on lock body 19 desired locations, make main, pay

lock core

2,16 and can only rotate by dead axle relative to lock body 19.Gear-box 7 is connected with junction plate 8 with lock body 19.In the lower surface of lock body 19, be positioned at key socket 17a, the 18b place all is equipped with anti-drilling catch 18a, 18b.

Embodiment 2: with reference to Fig. 2, this safety anti-theft lock is that main lock core rotates, and pays not rotation lock of lock core, and its basic structure is identical with embodiment 1, and difference is, the gear shaft 11b front end of gear 12b is connected with rotational lock 15 on being placed on pair lock core 16.Pay lock core 16 and be loaded on lock body 19 desired locations, a pair lock core 16 is not rotated relative to lock body 19, and rotational lock 15 tackles lock core 16 rotations mutually by spacer pin 3.Setting prevents that rotational lock 15 is along the spacing jump ring 14 of paying lock core 16 axial motions on the lock core 16 paying.For ease of assembling, on rotational lock 15, be connected with junction plate 13.
