Abstract

The utility model discloses a bicycle expansion brake lock that is used to solve the problem that locks of prior technology are separated from bicycles and the bicycles are easy to steal. The lock comprises a shell and a brake plate that is on the inner side of the shell and fixed with the bicycle back wheel. The circumferential side of the shell is provided with a locking head with a lock pin and the end of the lock pin is provided coaxially with a small cam. The brake plate is a cover-shaped round plate with an opening facing the shell. At least one lockhole is arranged around the brake plate. The shell is provided with a locking arrangement matching the brake plate on the side facing the brake plate. The expansion brake lock that adopts the above structure and combines the brake system and the lock device into one. The brake system and the lock device are interlocked and do not disturb each other. When the bicycle is locked, the back wheel can not rotate, and even if the locking head is destroyed, the bicycle can not be taken away. When the bicycle is unlocked, the back wheel is free, and the property of running and the function of brake are not affected. The utility model can be used for various bicycles, especially for existing electric bicycles.

Description

The bicycle expansion brake lock
Technical field
The utility model relates to a kind of lockset, particularly a kind of Electrical Bicycle expansion brake lock.
Background technology
The lock that rises is a kind of service brake device of bicycle, normally by being fixed on coaxial on a bicycle rear wheel shaft brake disc with wheel shaft, two shoe pieces compositions that are positioned at the outer housing of brake disc and are arranged on housing, shoe piece is crescent shape and is fixed in the interior brake disc circumference of housing, one end of its two shoe pieces is fixed together and is installed on the housing, the other end and balance pivot are connected, pass through brake linkage, like this, when the tension brake cable, shoe piece then outwards expands on the inside circumference of brake disc, form bigger friction force, thereby reach the brake purpose.This brake modes is simple in structure, and braking effect is better, has been subjected to people's welcome.But this brake gear function singleness belongs to two independently parts with existing anti-theft lock for bicycle, and the anti-theft column lock thief that is stolen destroys, and bicycle promptly can be had things stolen.
The utility model content
In order to overcome above-mentioned defective, the utility model purpose is to provide that a kind of to collect rise lock and anti-theft column lock of improvement be the bicycle expansion brake lock of one.
For achieving the above object, bicycle expansion brake lock of the present utility model comprises housing and is positioned at housing one side being fixed on brake disc on the wheel, is provided with the tapered end with lock core in described housing circumference one side, is coaxially arranged with a little cam in the end of lock core; Described brake disc is the lid shape disk of an opening towards housing, is provided with at least one lockhole along the brake disc circumference; On described housing, also be equipped with one with the suitable lock device of brake disc, described lock device is in a side of brake disc; In described lock device, be provided with a little cam, it connects the tapered end of lock core: be provided with a suitable locking bolt of described lockhole above described little cam, be provided with and the suitable chute of described little cam in described locking bolt bottom one side, on described housing, be provided with and the suitable rail groove of described locking bolt; When reversing lock core, rotate little cam by tapered end, drive the chute be located at the locking bolt bottom surface, make the rail groove telescopic slide of locking bolt on the housing.
Adopt the expansion brake lock of said structure, be brake system and lock device to be combined closely be integral mutual interlock and do not disturb mutually again, when car is locked, even can not being rotated, wheel destroys tapered end, also car can't be ridden away, trailing wheel is in free state when lock is opened, and does not influence train operation performance and brake holding function.

Fig. 2 is the structural representation of the utility model bicycle expansion brake lock brake disc part.
Fig. 3 is the structural representation of the utility model bicycle expansion brake lock back portion.
Fig. 4 is the structural representation of the utility model bicycle expansion brake lock front portion.
Fig. 5 is the utility model bicycle expansion brake lock cross-sectional schematic shown in Figure 1.
Fig. 6 is the little cam structure scheme drawing of the utility model bicycle expansion brake lock shown in Figure 1.
The specific embodiment
Extremely shown in Figure 6 as Fig. 1, the utility model bicycle expansion brake lock, comprise housing 1, be positioned at housing 1 one sides and be fixed on brake disc 3 on the wheel, be provided with tapered end 2, be coaxially arranged with a little cam 8 in the end of lock core with lock core in described housing 1 circumference one side; As shown in Figure 2, above-mentioned brake disc 3 is the lid shape disk of an opening towards housing, is provided with at least one lockhole 15 along the brake disc circumference; As shown in Figure 5, on above-mentioned housing 1, also be equipped with one with the suitable lock device of brake disc 3, described lock device is in a side of brake disc 3; Be provided with a little cam 8 in described lock device, it connects the tapered end 2 of lock core; Above described little cam 8, be provided with a suitable locking bolt 6 of described lockhole 15, be provided with the chute suitable, on described housing 1, be provided with the rail groove 16 suitable with described locking bolt 6 with described little cam 8 in described locking bolt 6 bottoms one side; When reversing lock core, by the little cam 8 of tapered end 2 rotation, drive the chute that is located at locking bolt 6 bottom surfaces, make rail groove 16 telescopic slide of locking bolt 6 on the housing 1.
Lockhole 15 on the above-mentioned brake disc 3 and locking bolt 6 can be provided with a plurality of according to actual needs, as three, six etc.A plurality of lockholes are set have increased the probability that locking bolt in the lock car process stretches into lockhole.Square locking bolt is set increases lock car intensity.
The utility model working process is such, and when needs locks car, screw key drives little cam 8 and rotates, and makes locking bolt 6 along with rail groove 16 outside (or interior) shifts out, and makes locking bolt 6 stretch to lockhole 15 on the brake disc 3, thereby finishes the lock car.
But above-mentioned structure needs rotating-wheel in lock car process, make locking bolt 6 just match just can reach and lock the car purpose with lockhole 15, therefore as further improvement of the utility model, the width of above-mentioned chute and rail groove 16 degree of depth add that the lift of little cam 8 is suitable, and are provided with spring 7 in the lower end of above-mentioned locking bolt 6.Like this, when lock is in locking state, if lockhole and locking bolt 6 can not be when last, because width≤rail groove 16 degree of depth of chute add the lift of little cam 8,, and before bicycle, carry out a segment distance or wheel certain angle so that lock core can't be twisted is motionless, when making locking bolt 6 relative with lockhole, since the effect of spring 7, and locking bolt 6 is ejected, thereby make locking bolt stretch into lockhole lock is lived.
The utility model expansion brake lock is brake system and lock device to be combined closely be integral mutual interlock and do not disturb mutually again.When car is locked, even can not being rotated, wheel destroys tapered end, also car can't be ridden away.Trailing wheel is in free state when lock is opened, and does not influence train operation performance and brake holding function.
