The utility model is adaptable to electric assisted bicycles and motorcycles.
Description
Technical field
The utility model relates to the servo brake lock that uses in a kind of electric motor car, relates more specifically to a kind of novel follow-up gate lock with angle.
Background technology
The electric motor car that uses is gone up by society at present, because the volume of electric motor car can not can conveniently be installed lock as bicycle greatly, therefore, people's end on electric vehicle brake is provided with lock.Disclosed Chinese patent 2004200216353.X, this lock be because complex structure, and decorative panel is housed in the electric motor car, causes unlatching very inconvenient; In addition, Chinese patent 200620165349.1 disclosed tapered ends and 200620073867.0,200720039964.2 disclosed binomial servo brake locks, all be to insert key could open from the rear end, therefore after being installed in the electric motor car, servo brake lock is close to motor casing, and motor casing and Wheel are connected as a single entity, when hand takes key to insert tapered end, arm at first will enter wheel face, and it is very inconvenient to open.I apply for 2008201521222 locks, though improve to some extent on opening angle, have the hole on the lock core, and the inboard in hole has recess, complex structure, and run into lock core diameter hour, and intensity reduces and influences the life-span.
Summary of the invention
The utility model is to overcome in the prior art not bring close shortcoming of opening inconvenience with wheel because of tapered end has angle, a kind of not only opened convenient but also servo brake lock simple in structure are provided, the utility model purpose is to realize like this, comprise key, lock body, lock core, roller ball, drive link, screw-casing, spring latch, the front end and the roller ball of lock core fixedly are connected as a single entity, roller ball is provided with scroll box, have the roller ball hole on the connecting rod, the both sides in hole have recess, and roller ball places in the rolling hole, and the recess in scroll box and rolling hole is complementary, the angle of lock core and drive link is greater than 5 °, the drive link other end places in the screw-casing, and the screw-casing inboard has helicla flute, and the axis of rolling is set on the drive link, the axis of rolling and helicla flute are complementary, swivel nut one end is provided with spring, dead bolt, the lock body inboard is provided with projection, has groove around the drive link, projection and groove are complementary, or the lock body inboard has groove, and drive link is provided with projection, and groove and projection are complementary.
The utility model is owing to disposed roller ball between lock core and power transmission shaft, roller ball is provided with scroll box, rolls to fixedly connected with lock core soon, and the angle between the drive link is greater than 5 °, can not solve and open inconvenient shortcoming thereby make to be locked in when using near wheel.
