Description

The double anti-theft padlock

The utility model relates to a kind of lock, relates to a kind of double anti-theft padlock specifically.

Generally the padlock of usefulness has two kinds at present, be exactly single spring lock and Double-spring lock, the more single spring lock of Double-spring lock theftproof performance is much better, Double-spring lock respectively blocks latch hook by a snap in the section of opening of lock and the fixed position of latch hook, so the user thinks that other more general locks of this type of lock use more reliable, the structure difference of two snaps of Double-spring lock, the snap of kayser hook standing part is a tack, and the snap head at the section of opening position is oblique, and this is convenient when having considered for the lock lock.See that from lock core structure keyhole is up logical.This class two-man act padlock exists following shortcoming: during the lock lock, the plagiocephaly snap of the lock section of opening is toward resilience, when the grab of latch hook during to certain position snap eject again and block latch hook, because during the lock lock, the snap of the lock section of opening ejects when grab is crossed snap again and blocks lock toward resilience, can make snap eject in grab with same reason in the time of the lock keyed so, if make half hole type utensil, insert from snap top along latch hook and also can make snap in grab, eject with tagger.Use Double-spring lock, two snaps are simultaneously toward resilience, in the time of can locking when opening the lock with the key, lock core is not moving, snap rebounds equally and ejects and block latch hook, and this just illustrates that lock core does not rotate, and also can come resilience to snap, if making hook with rigid iron wire injects in the lock from keyhole, rotate the iron wire hook in the time of to the end, the snap that does not eject in the grab can be ejected in grab, even also lock can be opened without key like this, so still there are a lot of problems in the theftproof performance of two-man act padlock.

The purpose of this utility model is to provide a kind of theftproof performance good, simple in structure, the dual padlock that arrives repeatedly that cost is low.

The purpose of this utility model is achieved through the following technical solutions:

The double anti-theft padlock comprises lock body, lock core, snap and latch hook composition, its structural feature is: said snap head is a tack snap head, the groove of kayser spring head is the anti-allocating slot corresponding with the snap head on the said latch hook, and the latch hook head of said latch hook is a plagiocephaly latch hook head.

Anti-plectrum is installed on the lock core of said band keyhole.

Advantage of the present utility model is:

Owing to change the snap head at the lock section of opening place into tack by plagiocephaly, so just can effectively avoid unblanking with iron plate, change the latch hook head into plagiocephaly simultaneously, so just to have avoided because of change influences the lock lock, result of use is good, and theftproof performance is strong, and can unblank smoothly and shut; The utility model is further installed anti-plectrum, can effectively prevent to use in keyhole group locks such as iron wire hook; The utility model theftproof performance is good, and is simple in structure, and cost is low.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1 is the utility model snap schematic diagram;

Fig. 2 is the utility model latch hook schematic diagram;

Fig. 3 is the anti-plectrum schematic diagram of the utility model.

As Figure 1-3, the utility model comprises lock body, lock core, snap 1 and latch hook 3, the snap head of snap is a tack snap head 2, the groove of kayser spring head is the anti-allocating slot 4 corresponding with the snap head on the latch hook, the latch hook head of said latch hook is a plagiocephaly latch hook head 5, and anti-plectrum 6 is installed on the lock core of said band keyhole.Change the snap head into tack snap head, just can effectively avoid unblanking with iron plate, for making the lock lock unaffected, simultaneously the latch hook head is changed into plagiocephaly latch hook head, so just need the degree of depth in lock hole is deepened, the corresponding lock body also should being increased, prevent to dial the anti-plectrum that snap is unblanked owing to be equipped with, thereby can play the double anti-theft performance, can make things convenient for again and unblank smoothly with iron wire etc., the utility model is simple in structure simultaneously, and cost is low.

Claims (2)

1, a kind of double anti-theft padlock, comprise lock body, lock core, snap (1) and latch hook (3) composition, it is characterized in that: said snap head is a tack snap head (2), the groove of kayser spring head is the anti-allocating slot (4) corresponding with the snap head on the said latch hook, and the latch hook head of said latch hook is a plagiocephaly latch hook head (5).
