Description

Embedded in front fork lock for bicycle

The utility model relates to bicycle lock.

The bicycle lock kind is a lot, and according to different rear wheel lock and the front-wheel locks of dividing in installation site, the front and rear wheel lock all is the purpose that reaches the lock car with lock pin resistance steel rolling silk.Another kind of bicycle lock is mounted in the tap, and the rotation of rolling handle-bar with resistance reaches lock car purpose, as:

CN89211663.3

But it is many that existing such locks part, processing, trouble is installed.

The purpose of this utility model is before design a kind of lock body and lock core are embedded in the fork shaft, passes spider and front fork central siphon wall and hinders and roll the bicycle lock that tap rotates with lock pin.

Front fork built-in type bicycle lock of the present utility model, have lock body and lock core, lock body and lock core are installed in the bicycle front fork axis hole, respectively open key hole and lockpin hole on spider and front fork axial wall, lock pin passes spider and front fork central siphon wall, and lock pin matches with lock core.

Front fork built-in type bicycle lock of the present utility model has lock bolt in lock body, lock bolt one end connects spring, and the lock bolt other end matches with groove on the lock pin, in the middle part of the lock bolt chute is arranged, and chute links to each other with lock core.

Front fork built-in type bicycle lock of the present utility model, this lock core middle part is fluted, and groove matches with lock pin.

Front fork built-in type bicycle lock of the present utility model, the structure of this lock is similar to spring padlock commonly used, make the arc link of former spring padlock into the straight-bar lock pin, the lock body of making is embedded in the front fork axis hole together with lock core, on spider and preceding fork shaft, have key hole and lockpin hole.When locking, lock pin inserts spider and preceding fork shaft enters axis hole, and lock pin is stuck under the lock core effect; When unblanking, the key hole that key inserts spider and preceding fork shaft enters in the lock core, reverses behind the lock core lock pin and extracts with bicycle and break away from.The processing of this bicycle lock almost spring padlock with commonly used is identical, produces easily, and cost is low, and it is very convenient to lock, and theftproof performance is good.
