Description

Insert wushu cipher anti theft lock

The utility model relates to a kind of theftproof lock that is applicable to vehicles such as bicycle, motorcycle, relates to a kind of slotting wushu cipher anti theft lock specifically.

In recent years, bicycle, motorcycle stolen to become a comparatively general bad social phenomenon, for preventing the rising of this type of case, it is that bicycle, motorcycle have been designed multiple theftproof lock that many inventions are gone into, and is exactly a kind of a kind of lockset that has been widely used at present and insert the wushu cylinder lock.Above-mentioned this lock is that the U-shaped that lock body that lock cylinder is housed is arranged, be used for that lock body is fixed in the solid locker plate on the vehicle frame (fork) and be plugged in the lock body lockhole is inserted forming, the lock of this structure was compared with former lock, and its theftproof performance is significantly improved.But also exist weak point in actual use, though being difficult for the scene as stealer pries open it, but the thief often can adopt the way of destroying lock core lock to be opened (lock core mostly is copper structure as occasion serves, the thief adopts the method for brill that it is destroyed more), can easily lock body be unloaded from vehicle frame after unblanking.

The purpose of this utility model is in order more effectively to solve bicycle, the stolen problem of motorcycle, provide a kind of whole anti-destructive of lock body better on the basis of above-mentioned weak point of the prior art overcoming, and other people difficulty or ease a kind of slotting wushu cipher anti theft lock that lock body is separated with vehicle frame.

The purpose of this utility model can adopt following measure to realize:

The U-shaped that slotting wushu cipher anti theft lock of the present utility model comprises lock body, be used for that lock body is fixed in the solid locker plate on the vehicle frame and be plugged in the lock body lockhole is inserted; Its lock body is provided with the blank chamber that cipher wheel is installed, and the two side in the blank chamber of lock body is provided with the installing hole that is used for plug-in mounting coded shaft bolt, and this hole communicates and its intersect vertical axis with lockhole on the lock body, and a plurality of cipher wheel are sleeved on the coded shaft bolt; Being arranged on the screw hole that being used on the lock body connect solid locker plate is the hole countersunk structure, and the countersunk head end in this hole is positioned on the stomach wall that the blank chamber of cipher wheel is installed.

The construction profile of lock body can be the concave shape structure in the utility model, and cipher wheel is contained in the formed blank chamber, depression position of concave shape structure; Lock body in the utility model also can be a three-back-shaped structure, and cipher wheel is arranged in the blank chamber of lock body middle part; Be positioned on the lock body on the coded shaft bolt that leaks cavity segment and be set with four cipher wheel, adopt affixed mode that a cipher wheel is installed at the end of coded shaft bolt.

Because due to the integral structure characteristic of lock of the present utility model, make that each component all can adopt pick-proof, anti-drilling, anti-ly pounds, the good material of anti-saw property is made; The utility model is the unlatching that realizes locking with permutation and combination digital on five digit wheels in addition, and this just makes the utility model reliability, confidentiality be improved; In addition lock body and vehicle frame to be connected what adopt be to hide the screw-type connected mode, thereby realized not destroying the purpose (experimental results show that the intensity of the intensity of lock) that cryptography architecture just can't separate lock body and vehicle frame far above vehicle frame, even make the thief that car is stolen also and car can't be sold, reach the purpose that stops the car thief to continue to steal.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a front view of the present utility model.

Fig. 2 is the sectional view of lock body among Fig. 1.

Fig. 3 is the sectional view of second kind of embodiment of the utility model lock body.

The utility model is done with detailed description below with reference to embodiment (accompanying drawing):

As shown in Figure 1, 2, the slotting wushu cipher anti theft lock of the present utility model U-shaped that comprises lock body (1), be used for that lock body is fixed in the solid locker plate (4) on the vehicle frame and be plugged in lock body lockhole (10) is inserted (2); Its lock body (1) construction profile is concave shape structure (as shown in Figure 2), the two side at lock body depression position (11) is provided with the installing hole (9) that is used for plug-in mounting coded shaft bolt (5), this hole (9) communicates and its intersect vertical axis with lockhole (10) on the lock body (1), be positioned on the coded shaft bolt (5) of the formed space segment in lock body (1) depression position (11) and be set with four cipher wheel (6), a cipher wheel (12) is installed in the affixed mode of end employing of coded shaft bolt (5); Being arranged on the screw hole that being used on the lock body (1) connect the screw (3) of solid locker plate (4) is the hole countersunk structure, and the countersunk head end (8) in this hole is positioned on the stomach wall (13) that the blank chamber of cipher wheel is installed.Figure mesopore (7) is to insert the jack that U-shaped is inserted handle after being used to unblank.

As shown in Figure 3, the lock body of lockset (1) also can be a three-back-shaped structure in the utility model, and the blank chamber (11) of lock body (1) middle part is the installation place of cipher wheel (6), and other structure is same as last embodiment.

Mounting method of the present utility model is as follows:

Earlier cipher wheel and coded shaft bolt are unloaded from lock body, lock body and solid locker plate spiral-lock (are being processed and the similar arc groove of vehicle frame shape of cross section respectively on lock body and the solid locker plate) on the rear crotch or front fork of bicycle or motorcycle, from the screw mounting hole that is positioned on the stomach wall of the blank chamber of lock body installation cipher wheel attachment screw is inserted and tightens then, again cipher wheel and coded shaft bolt are loaded onto afterwards and are got final product, attachment screw is hidden bury and cipher ring and lock body wall between.Even this structure and its mounting means have guaranteed that the bicycle that the utility model lockset is installed goes adrift, also lock can't be uncarted (component on the lockset all adopt pick-proof, anti-drilling, the anti-good material of pounding property to form), stolen vehicle can't be sold.
