Abstract

The utility model relates to an anti-theft padlock which comprises a lock body (2), a lock core (3) and a lock rod (1). The utility model is characterized in that the lock core is arranged in a lock core sleeve after the lock core is assembled with marbles, the end part of the lock rod and the visual part of the lock rod when in unlocking form a step shape of which the cross section is different, for example, the lower cross section is small, and the upper cross section is large. A lock hole is also in a step shape of which the upper part is big and the lower part is small, the lock rod is matched with the lock hole, and the lock rod and the lock hole are distributed at the right side and the left side of the lock body and are mutually symmetrical in a step shape with different cross sections. The utility model overcomes the defects that the marble holes of the lock core are disclosed out and the lock rod and the lock hole of the traditional padlock are matched in the same cross section mode, and effectively enhances the anti-theft function.

Description

Theft proof padlock

Technical field: the utility model relates to the improvement invention of common padlock, particularly be a kind of lock

Built-in and locking bar in core pellet shot from a slingshot hole and lockhole all are stairstepping different cross section and coupling mutually

Theft proof padlock.

Background technology: in the prior art, theft proof padlock is of common occurrence, its structure included lock body,

Lock core and locking bar, but after the lock core of this padlock and the pellet shot from a slingshot assembling, its pellet shot from a slingshot hole is located at lock housing

, seal pellet shot from a slingshot with tin sheet or copper sheet outward, the whole process of its locking bar is same cross section, because locking bar

The cross section identical, the cross section of its lockhole also is identical, therefore, in traditional padlock,

This is two big shortcomings, and the burglar scrapes off mounting easily with the special tool prodigiosin first, emits pellet shot from a slingshot and beats

Unlocking tool is committed theft, and second inserts the slit of locking bar and lockhole with iron plate, can prize dead bolt and open

Lock, even can steal in the laggard every trade of the situation of not destroying the lockset profile, stable society given

Environment stays hidden danger.

Summary of the invention: in view of the problem that known technology exists, the purpose of this utility model aims to provide a kind of

Theft proof padlock scientific and reasonable for structure, that theftproof performance is strong.The utility model is as follows

Finish: this theft proof padlock includes lock body, lock core and locking bar, it is characterized in that lock core with

Be located at after the pellet shot from a slingshot assembling in the lock core cover, the end of described locking bar and locking bar when unblanking as seen

The position is the stairstepping of up big and down small different cross section, and described lockhole also is last big following ladder

Shape, described locking bar and lockhole are complementary.Described locking bar and lockhole are the stairstepping of different cross section

Be arranged in about the lock body both sides symmetrical.The utility model is compared with known technology, has

Scientific and reasonable for structure, theftproof performance is strong, according to preventing of the utility model design motif made

Steal padlock, will produce positive effect to social safety.

Description of drawings: the utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment: accompanying drawing has been represented structure of the present utility model and embodiment, below combination again

Accompanying drawing further describes each relevant details of embodiment.Whole lockset include lock body 2,

Lock core 3 and locking bar 1, the metal material of lock body 2 and locking bar 1 is all made with high-frequency quenching,

3 of lock cores are made with brass, its mainly create part be with after lock core 3 and the pellet shot from a slingshot assembling again

The core retainer plate that locks is built-in, and it two is processed into mutual coupling with lockhole and locking bar 1

The stairstepping of up big and down small different cross section, like this, because up big and down small and one-tenth stairstepping is stolen

The thief but can't enter with the slit, top that special tool promptly enables to insert locking bar 1 and lock core 3

Lock core 3 is pried open dead bolt, has greatly improved theftproof performance.Though this innovation and creation are not

High-new difficult technology, but compared with prior art, have substantive distinguishing features and progress, give stable

Social environment will bring positive effect.

Claims (2)

1, a kind of theft proof padlock, include lock core (3), lock body (2) and locking bar (1), it is characterized in that being located in the lock core cover after described lock core (3) and pellet shot from a slingshot assemble, visible position when described locking bar (1) is unblanked with the end of locking bar is the down little stairstepping of different cross section, described lockhole is the up big and down small stairstepping that is different cross section, and described locking bar and lockhole are complementary.

2, theft proof padlock as claimed in claim 1 is characterized in that stairstepping that locking bar and lockhole are different cross section is arranged in about the lock body both sides symmetrically.
