Background technology

Existing various motor bike or the theft-proof means of battery-driven car be mostly rely on head lock or with common steel cable lock as electronic lock, front-wheel or trailing wheel by the locking battery-driven car prevent stealing, but the theftproof performance of head lock is very limited, and the lockset of this class of steel cable lock and battery-driven car itself are independent of each other, lack disguise simultaneously, be easy to be found and picking lock robber car by the robber.

Summary of the invention

The purpose of this utility model is at the not enough defective in the above-mentioned battery-driven car lock technology, and a kind of and motor bike or electric bicycle brake wheel hub one, brake hublock tapered end easy to use are provided.

For achieving the above object, the utility model adopts a kind of brake hublock tapered end, comprise outer lock body, interior lock body, lock core and lock, outer lock body is provided with the slippage chamber of the ccontaining interior lock body of axial perforation, interior lock body is a column, the tail end of interior lock body is provided with retracing spring, the other end of retracing spring is pressed on the slippage chamber, be provided with the storage chamber that holds lock core and lock in the interior lock body vertically, lock core can be rotatably set in an end in storage chamber, lock is arranged on the lock core tail end, and it is external that the free end of lock exposes internal lock, is provided with between outer lock body and the lock core the rotation-sliding action of lock core and the link gear that constitutes interlock that moves axially of lock.

As further setting of the present utility model: the tail end of lock core radially is vertically installed with the transmission pin, offer the positioning groove that rotates for the transmission pin with the cooresponding interior lock body upper edge of transmission pin circumferencial direction, offer the positioning runner at band turning outside on the slippage chamber wall of lock body, the diameter of the width of positioning runner and transmission pin adapts, transmission pin one end drops on and constitutes the rotation-sliding cooperation in the positioning runner, forms above-mentioned link gear.

In order to improve the locking of tapered end, this practicality further is set to storage chamber one end that lock is arranged on interior lock body movably, constitute free-running fit with the through hole on the interior lock body, between lock core and lock, be provided with grid plate, the fixed end of lock forms the spring perch of compression spring, and the other end of compression spring is pressed on grid plate one side.

In order to prevent that the transmission pin from coming off, the positioning runner outside that this practicality further is set on the outer lock body is correspondingly provided with the pin baffle plate.

As further setting of the present utility model: corresponding grid plate position offers open slot on the interior lock body circumference, offer the location square hole on the lock body circumference in the opposite side of open slot relatively, grid plate one side is provided with and locatees the locating piece that square hole formation location cooperates.

The utility model is by providing the brake hublock tapered end that only is made of inside and outside lock body, lock core and lock, structure is very compact, directly design and installation forms one on hub shell, during use with usually seemingly phase-locked, make the lock slippage that the hublock ring of motor bike or battery-driven car is formed the purpose that locking reaches the pinning vehicle, therefore very convenient.

The specific embodiment

As Fig. 1,2,3, shown in 4, this practical specific embodiment is that a kind of brake hublock tapered end comprises outer lock body 1, interior lock body 2, lock core 3 and lock 4, as shown in Figure 5, outer lock body 1 is provided with the slippage chamber 11 of the ccontaining interior lock body 2 of axial perforation, as Fig. 6, shown in 7, interior lock body 2 is a column, the tail end of interior lock body 2 is provided with retracing spring 5, the other end of retracing spring 5 is pressed on the slippage chamber 11, be provided with the storage chamber 21 that holds lock core 3 and lock 4 in the interior lock body 2 vertically, lock core 3 can be rotatably set in an end in storage chamber 21, the tail end of lock core 3 radially is vertically installed with transmission pin 6, with the positioning groove 22 that along the circumferential direction offers on the transmission pin 6 cooresponding interior lock bodies 2 for 6 rotations of transmission pin, offer the V-shaped positioning runner 12 at band turning outside on slippage chamber 11 walls of lock body 1, the width of positioning runner 12 is greater than the diameter of transmission pin 6, transmission pin 6 one ends drop on and constitute the rotation-sliding cooperation in the positioning runner 12, and positioning runner 12 outsides on the outer lock body 1 are correspondingly provided with pin baffle plate 9.Lock 4 is arranged on storage chamber 21 other ends movably, constitute free-running fit with the through hole 23 on the interior lock body 2, the free end of lock 4 is by outside the lock body 2 in exposing, between lock core 3 and lock 4, be set with grid plate 7, corresponding grid plate 7 positions offer open slot 24 on interior lock body 2 circumference, offer location square hole 25 relatively in the opposite side of open slot 24 on lock body 2 circumference, grid plate 7 one sides are provided with and locate the locating piece 71 that square hole 25 formation location cooperate.The fixed end of lock 4 forms the spring perch of compression spring 8, and the other end of compression spring 8 is pressed on grid plate 7 one sides.

Lock 4 in the foregoing description is storage chamber 21 other ends of lock body 2 in being movably arranged on, corresponding compression spring 8 is set for simultaneously lock 4.Constitute locking as long as can allow lock 4 stretch out, also can adopt through hole 23 to constitute interference fit method lock 4 and interior lock body 2 with interior lock body 2 slippages and from the exterior lockhole 13 of outer lock body 1.

As shown in Figure 8, the brake hublock tapered end that this practicality is implemented is fixed on wheel hub shell 15 1 sides of motor bike or battery-driven car, and relative set constitutes the lockhole that locking radial cooperates with the lock 4 of brake hublock tapered end on the circumference of wheel hub lock ring 16.When wanting locking, key is inserted rotational lock core 3 in the lock core 3, transmission pin 6 on the lock core 3 positioning groove on interior lock body 2 22 earlier rotates, move along vee-type positioning runner 12 then, make whole interior lock body 2 slippage chamber 11 interior the slips and compression reseting springs 5 of lock body 1 outside, the locks 4 in the interior lock body 2 are compressed in the tapered end, in case the wheel hub rotation, can realize locking, need not be specially for aligning the lockhole rotating-wheel.

The utility model after guaranteeing to unblank, has only key could realize locking by transmission pin 6 positioning runner 12 motions of lock body 1 outside, and the situation of mistake lock can not take place.Positioning runner 12 outsides on the lock body 1 are correspondingly provided with pin baffle plate 9 outside, even transmission pin 6 is loosening like this, also can not come off, and have guaranteed the anti-error lock function of transmission pin 6, have also reduced the pollution of dust to lock core 3 simultaneously, prolong the life-span of lock core 3.

Brake hublock tapered end of the present utility model both can be used for band-type brake also can be used to the lock that rises.
