CN2206329Y - Digital code lock - Google Patents

Abstract

The utility model provides a digital code lock, which is composed of a lock body and a lock beam. The lock body comprises a base, an upper cover which is matched with the base and a moving coil which is rotated by winding the base. When a plurality of digital codes combined on the moving coil are wrong, a semi-circular notch on the lock beam is fastened by the moving coil, and the lock is in a closed state. When the combined digital codes are correct, a semi-circular hole on the moving coil and a semi-circular groove on the base compose a complete circle, the complete circle is concentric with the cross section of the lock beam, one end of the lock beam can be pulled out of the lock body, and the lock can be opened. The utility model has the advantages of no spring, no cylinder, high intensity and strong anti-theft performance, and is suitable for being used in bicycles, motorcycles, steel gates and wooden gates.

Description

Digital code lock

The utility model relates to a kind of lock class, particularly relates to a kind of combination padlock.

Lock is of a great variety at present, uses object different, and for example coded lock is mainly used in safe door, and password is set by the user, complex structure.And the lock of uses such as bicycle, motorcycle mostly is mechanical cylinder lock, and its theftproof is relatively poor, needs to use key, uses inconvenient.

The new purpose of this practicality is to provide a kind of combination padlock that bicycle, motorcycle etc. reach steel, wooden gate that can be used for.

The utility model combination padlock is achieved in that it is made up of lock body and U-shape lock beam.Lock body comprises ⊥ type base, the T type loam cake that cooperates with whorl of base, and at least 4 moving-coils that rotate around base between base and loam cake generally are advisable with 4～6.The semi-circular recesses that two symmetries are wherein arranged on the base, a groove forms through hole on seating plane.On be stamped two symmetrical through holes.Moving-coil is the stepped ramp type circle that evenly indicates random order 0-9 numeral on the external surface, and two symmetrical semicircle orifices are arranged on inner ring.Lock bridge one end has the cap head, makes lock bridge have only an end can be drawn out lock body, and the semicircle breach that cooperates with moving-coil is arranged on the lock bridge, and the diameter of lock bridge is slightly less than the diameter of loam cake through hole, moving-coil semicircle orifice and base semi-circular recesses, and lock bridge can be slided therein.

Operating principle of the present utility model is, the numeral of first circular hole correspondence of each moving-coil sets in advance during fabrication, when the numeral of first circular hole correspondence of all moving-coils is vertically alignd, moving-coil semicircle orifice and base semi-circular recesses constitute full circle, and lock bridge one end just can be pulled out from lock body, and lock is opened, otherwise, semicircle breach on the lock bridge will be blocked by moving-coil, and lock bridge can not be pulled out lock body, and lock is in closure state.Even lock bridge is cut off, lock bridge still can not be got lock body.

The advantage of the utility model combination padlock is not have spring, non-marble, no key, intensity height, and shock-resistant, erosion resistant, theftproof are strong, and long service life is suitable for bicycle, motorcycle etc. and steel, wooden gate is used.

Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
