Description

Bicycle lock

The utility model relates to the lock that a kind of bicycle uses.

At present the lock that uses of bicycle, trishaw mainly contains crab shape lock and chain (or steel cable) lock, and using such lock lock car all is that front-wheel or trailing wheel are locked, and loses or stolen with anti-vehicle.Because the relation of lock construction, lock is very easily pried open or is destroyed, so that often the generation vehicle is lost or be stolen.

The purpose of this utility model provides a kind of by front-wheel and vehicle body are carried out directional lock, and vehicle frame is can not the left and right sides rotating, and lock body intensity is big, be difficult for being pried open or ruined, is suitable for the lock that bicycle and trishaw use.

Lock rotates return spring (14) by lock body (1), lock pin (2), lock core (4), lock pin return spring (3), lock core marble (12), marble spring (13) and lock core and constitutes, connecting thread is arranged on the lock body, can be on the handlebar axis axle sleeve by connecting thread with the lock fixed connection.The lock body lockpin hole is a through hole, and lock pin is positioned at through hole, and the upper and lower displacement of lock pin has annular shoulder on the extended lock body lock pin in lock pin end, and the lock pin hole wall has annular shoulder, and the lock pin return spring is loaded between two shoulders, and is located by shoulder backstop.Lock core is vertical with lock pin, and lock core, pellet shot from a slingshot, marble spring and lock body assembly structure are identical with existing billiards lock structure.There is the tangential section breach lock core and lock pin cooperation place, and there is the arc groove that adapts with the lock core external cylindrical surface lock pin and tangential section breach cooperation place.

Lock monomer lock core hole has radially half groove, and half groove of symmetry is with it arranged on the half groove opposite position lock core, and the two halves groove constitutes the pin core and rotates the return spring hole, and lock core rotates return spring and is loaded in the hole.

When using the lock that the utility model provides, plug out a lock pin perforation at lamp in advance, axle bumper bowl circular fold on the handlebar bearing is left cloth lock pin backstop groove along circumference.Lock is tightened and can uses on the handlebar axis axle sleeve.

Further improving of lock is that lock pin has pin (5), to prevent that lock pin is by deviating from the lockhole.

The unlatching of lock and sealed process are: use key turn lock core when unblanking, lock core is removed the block effect to lock pin when lock core breach plane is parallel with the lock pin cylinder, lock pin is return under the return spring effect, lock pin is by withdrawing from the axle bumper bowl backstop groove on the handlebar axis, lock promptly is unlocked, the vehicle state that unlocks.When sealed, lock pin is stretched in the clamping groove with lock pin under the hand.At this moment, the groove on the lock pin is corresponding with the lock core breach, and lock core return under the transposition spring action stretches in the groove lock core face of cylinder, and lock core is with the locking of lock pin block, and lock is promptly by sealed.

The lock that utilizes the utility model to provide is fixed with lock, can make front-wheel and vehicle body keep a fixing angle, vehicle can not be ridden also can't carry out.Lock lock body intensity is big, is difficult for being pried open and destroying, and is safe in utilization, reliable.

Accompanying drawing is an embodiment of the present utility model, further specifies the utility model below in conjunction with embodiment.

Fig. 1 is the assembly structure figure of lock.

Fig. 2 is Vehicle lock structure figure.

Fig. 3 is Fig. 2 upward view.

Fig. 4 is an A-A sectional view among Fig. 3.

Fig. 5 is axle bumper bowl structure figure on the handlebar bearing.

As shown in the figure, lock rotates return spring (14) formation by lock body (1), lock pin (2), lock core (4), lock pin return spring (3), lock core marble (12), marble spring (13) and lock core.The lock body annulus partly has the connection internal thread, is fixedly connected by screw thread lock body and handlebar (11) axle sleeve.The lock pin of lock body is a through hole, and annular shoulder is arranged at lockpin hole top.Lock pin is loaded in the lockpin hole, has on the lock pin and the corresponding annular shoulder of lockhole annular shoulder.The lock pin return spring is loaded on two shoulders of lock pin, and return spring backstop is located.Positioning runner is arranged at the lock pin bottom, and the corresponding chute of lock body lockpin hole place is fixed with the location pin (5) vertical with lock pin, to prevent that lock pin is by deviating from the lockpin hole.Lock core (4) is vertical with lock pin, and there is the tangential section breach its end.With on the lock pin bar of lock core breach corresponding position the arc groove that adapts with the lock core external cylindrical surface is arranged, lock core has pellet shot from a slingshot (12) and marble spring (13), lock core, pellet shot from a slingshot, marble spring assembly structure are identical with existing billiards lock structure.Radially half groove is arranged on the lock core, with the lock body lock core hole wall place of the radially half groove corresponding position of lock core half groove of symmetry is arranged, lock core half groove constitutes lock core with lockhole half groove and rotates the return spring hole, and lock core rotation return spring is loaded in the hole.Rotational lock core when unblanking, return spring is compressed.After discharging lock core, lock core rotates return under spring action.When utilizing lock lock car, insert with the lock pin corresponding position at lamp and to make a call to an open-work that lockpin ventilating is crossed, handlebar bearing upper bearing (metal) retaining bowl is made the backstop groove along axle bumper bowl circle distribution as graph structure.When sealed lock pin is depressed, the lock pin bottom is stretched in the backstop groove car front-wheel wheel face and vehicle frame is locked on a certain angle position, and vehicle can not be ridden can not be carried out.When unblanking, utilize key turn lock core, the plane of lock core flat-cut indentation, there and lock pin line parallel, the lock core face of cylinder is by withdrawing from the lock pin arc groove, lock pin is mentioned automatically in the return spring effect, and the lock pin bottom is by withdrawing from the bearing retaining bowl groove, and vehicle unlocks.Lock core rotates return spring and is compressed when unblanking rotational lock core, and lock is opened the back lock pin and mentioned automatically, and lock core flat-cut breach plane and lock face contact can not return, and lock core rotation return spring is in confined state all the time.It is corresponding with the lock core breach that the lock car is depressed behind the lock pin on the lock pin arc groove, and lock core rotates return rotating under the return spring effect, the lock core face of cylinder is stretched in the groove lock pin block is located, and lock is in locked state.
