Description

A kind of Novel anti-pick padlock

Technical field

The utility model relates to a kind of padlock, specifically, relates to a kind of Novel anti-pick padlock.

Background technology

Padlock is the most ancient historical lockset in the world, it is owing to use, easy to carry being widely used in everywhere, the padlock general structure is comparatively simple, easily chosen out or destroy lock core with instruments such as choosing pin by the thief on the one hand, cause it to be opened easily or locking bar can't locking, the draw-in groove that arranges at locking bar on the other hand makes locking bar itself, and firmly degree is inadequate, causes the pick-proof poor-performing of present padlock.

The utility model content

The purpose of this utility model is to provide a kind of Novel anti-pick padlock, and the structure that solves present padlock not firmly causes its lock core easily to be chosen out or destroy the problem that causes the pick-proof poor performance.

To achieve these goals, the technical solution adopted in the utility model is as follows:

A kind of Novel anti-pick padlock, comprise lock body, two ends all are inserted in the U-shape lock bar in the lock body, be arranged at the lock core in the lock body, one end of described U-shape lock bar is provided with dead bolt, and an end of lock core is provided with the fixture block that rotates with lock core, is provided with in the lock body for the cavity that lock core, fixture block, dead bolt, U-shape lock boom end are installed, dead bolt and fixture block all are positioned at the cavity of lock body and the locking that cooperatively interacts, and fixture block is provided with the draw-in groove that cooperates with dead bolt.

In order to guarantee sound construction, described U-shape lock bar and the dead bolt structure that is solidified as a whole.

Further, described U-shape lock bar is provided with between the end of an end of dead bolt and the lock body and is provided with return spring; As a kind of preferred, this return spring is Compress Spring.

Unblank and the locking convenience in order to make, described fixture block is fixedly connected with lock core, and fixture block is provided with back-moving spring; As a kind of preferred, this back-moving spring is torsionspring.

In order to guarantee application life and to increase the pick-proof performance, described lock body, U-shape lock bar, dead bolt, lock core and fixture block are made by metal material, wherein U-shape lock bar and dead bolt adopt boron alloy or manganese alloy to make usually, and lock body, lock core and fixture block adopt copper, carbide alloy or kirsite to make usually.

Compared with prior art, the utlity model has following beneficial effect:

(1) the utility model is simple in structure, designs ingeniously, easy to use, is fit to apply.

(2) the utility model utilizes the screens that cooperatively interacts of dead bolt and fixture block to play the purpose of locking, guaranteeing under the original lock function prerequisite of lock core, increased another heavy insurance, even it is bad that lock core is prized, fixture block can also continue to keep and the dead bolt locking, thereby increased the pick-proof ability, improved security performance.

(3) dead bolt of the present utility model makes dead bolt more firm by connected mode and U-shape lock bar formation integral body such as welding, has improved the integrally-built firm degree of U-shape lock bar, thereby has increased the pulling force of padlock, and then improved the pick-proof performance.

(4) the utility model is fixedly connected with fixture block with lock core, thereby guaranteed on the one hand and can regulate the function that the position of draw-in groove is unblanked its realization corresponding to dead bolt by lock core, improved on the other hand the firm degree of fixture block and lock core, jointly cooperate the firm degree that has improved the utility model integral body with lock body inner chamber and dead bolt, thereby increased the pulling force of padlock, further improved security performance.

(5) the utility model is by arranging return spring, unblank be draw-in groove and dead bolt at once, the U-shape lock bar can be upspring automatically opens, so that use the U-shape lock bar to pass other objects that need locking with its locking; By back-moving spring is set, be that dead bolt moves down when breaking away from draw-in groove in locking, make fixture block can automatic rotating with the position of draw-in groove and the dead bolt realization locking that staggers, use operate very convenient.

(6) the utility model locked groove that will have now on the locking bar is designed into lock body inside, and dead bolt is designed on the U-shape lock bar, avoided slotting on the impact of locking bar body solidness at locking bar, thereby improved the intensity of U-shape lock bar, strengthen the pulling force of padlock, and then improved security performance.

(7) the utility model adopts firm metal material to make, and has further improved the security performance of padlock integral body, has strengthened the performance of pick-proof and anti-theft.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples, and embodiment of the present utility model includes but not limited to the following example.

Embodiment

Shown in Fig. 1～3, this Novel anti-pick padlock comprises lock body 1, and two ends all are inserted in the U-shape lock bar 2 in the lock body, is arranged at the lock core 4 in the lock body; One end of U-shape lock bar 2 is provided with dead bolt 3, and in order to guarantee sound construction, U-shape lock bar and dead bolt are by the connected modes such as the welding structure that is solidified as a whole; One end of lock core 4 is provided with the fixture block 5 that rotates with lock core, and in order to strengthen fastness, fixture block is fixedly connected with lock core; Be provided with in the lock body for the cavity that lock core, fixture block, dead bolt, U-shape lock boom end are installed, for improving security performance, the outer part of lock body cavity is hatching solid, and cooperates comparatively closely with miscellaneous part, both guaranteed that it can normal rotation, guaranteed again that it can not become flexible; Dead bolt and fixture block all are positioned at the cavity of lock body and the locking that cooperatively interacts, and fixture block 5 is provided with the draw-in groove 6 that cooperates with dead bolt, and the size of common draw-in groove is big or small corresponding with dead bolt.

In order to improve simple operation, the U-shape lock bar is provided with between the end of an end of dead bolt and the lock body and is provided with return spring 7, this return spring is that draw-in groove and dead bolt are at once unblanking, the U-shape lock bar can be upspring automatically open, so that use the U-shape lock bar to pass other objects that need locking with its locking; As a kind of preferred, this return spring is Compress Spring.For make unblank and locking convenient, fixture block is provided with back-moving spring 8, this back-moving spring is that dead bolt moves down when breaking away from draw-in groove in locking, make fixture block can automatic rotating with the position of draw-in groove and the dead bolt realization locking that staggers; As a kind of preferred, this back-moving spring is torsionspring.

In order to guarantee application life and to increase the pick-proof performance, lock body, U-shape lock bar, dead bolt, lock core and fixture block are made by metal material, wherein U-shape lock bar and dead bolt adopt boron alloy or manganese alloy to make usually, and lock body, lock core and fixture block adopt copper, carbide alloy or kirsite to make usually.

The utility model inserts key in the lock core in use, and the twisting key rotates lock core and fixture block jointly, when draw-in groove turns to the position corresponding with dead bolt with fixture block, the return spring of U-shape lock bar lower end upwards promotes it, moves on the dead bolt to snap in the draw-in groove, can unblank; After unblanking, the U-shape lock bar is passed the object that other need locking, then press the U-shape lock bar it is moved downward with respect to lock body, dead bolt moves down in draw-in groove simultaneously, until dead bolt breaks away from draw-in groove, this moment, back-moving spring made the fixture block rotation cause draw-in groove and dead bolt dislocation, and is namely lockable.

According to above-described embodiment, just can realize well the utility model.
