Description

Anti-theft handle of bicycle

The utility model relates to a kind of bicycle assembly parts, particularly relates to a kind of bicycle theft-prevention handlebar.

Prevent that at present the various lock of the stolen most employing of bicycle from pinning bicycle rear, design the various bicycle front forks that pin later on again, frame lock integrated directed latching device or lock, as the turning of bicycle automatic lock, the directed pick-proof lock of front fork, directed latching device, the directed anti-joyride device of front-wheel etc., generally design on bicycle front fork or main shaft, pin back bicycle front-wheel can not about turn to, thereby can't ride.But this design can reduce front fork or main axe intensity, also easily causes lock to damage when firmly rotating handlebar.Chinese patent 1056086A discloses a kind of anti-joyride device, promptly on main shaft and handlebar geared assembly is set, and bicycle not time spent handlebar and main shaft jump out of mesh can't be ridden it.This geared assembly structure is very complicated, and handlebar takes off big, the Heavy Weight of back volume, carries inconvenience.

The bicycle theft-prevention handlebar that the purpose of this utility model is to provide a kind of simple in structure, lock and handlebar to be integrated.

The utility model is to realize like this, it comprises and is fixed on the fixer that turns to that has the U-shaped groove on the front-wheel main shaft, generally be connected as a single entity with Type of Welding and main shaft, be connected by turning cylinder and turn in the fixer groove, and abutting end is step left hand handle and the right handgrip that moving axis rotates that can rotate, with the nut that turning cylinder one end cooperates, its effect is turning cylinder to be fixed on turn on the fixer, and pass left hand and right hand abutting end with turn to fixer bonded assembly latch.Wherein be connected with lock hole element and the tapered end spare that corresponds to each other respectively on left hand handle and the right handgrip.Can be fixed on handgrip interlude place with welding or the form that is threaded,, be convenient to lock and damage back replacing lock hole element and tapered end spare wherein to be threaded to.Lock hole element and tapered end spare constitute general common pellet shot from a slingshot latch, and lock hole element is provided with the lock core that comprises big pellet shot from a slingshot, little pellet shot from a slingshot, shell fragment and spring, and the tapered end of tapered end spare inserts in the lock hole element lock core, lock can be pinned.

The utility model bicycle theft-prevention handlebar is installed on the bicycle, takes off when stopping latch, left and right handles is upwards rotated 90 ° to be closed up parallel, lock hole element and tapered end spare on the left and right handles are collided, tapered end inserts in the lock core left and right handles is locked together, the handlebar that bicycle lost balance and turned to this moment is so can not ride.Otherwise, during use left and right handles is rotated 90 ° respectively and becomes a horizontal linear, and latch is plugged to prevent that handgrip rotates in the use.

The advantage of the utility model bicycle theft-prevention handlebar is that handlebar and lock are combined as a whole, and pins bicycle by pinning handlebar, and is simple in structure, anti-theft is strong, and is easy to use, moreover, because left and right handles closes up upwards when stopping, so reduced the bicycle floor area, helps transport administration.

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