Description

Axle anti-theft lock

Affiliated technical field

The utility model relates to a kind of lockset, especially for the anti-theft column lock of locking bicycle back axle.

Background technology

Bicycle has adopted the multiple anti-theft measure that locks in order to prevent loss.Axle anti-theft lock is because of its more hidden, the safety in the position that locks, and the structure of lock and car one more can realize antitheft purpose.From Granted publication number is data such as CN2228115Y, and the lock core of employing, lock pin, lockhole locking method all are at the outside and the caudal furca place of bicycle shaft's axle intracutaneous steel ball, and the problem that their exist is that the slit of rotating mechanism is difficult for waterproof, rust protection.Strengthen the caudal furca socket in addition, need redesign cycle frame caudal furca mouth, lose commonality, opened socket, but taken the position of the lock brake thigh that rises and have mercy on.

The axletree lock will reach practical order ground should satisfy three conditions:

1, have commonality: the caudal furca socket is the general international standard size behind bicycle front fork, the vehicle frame.As 5 millimeters of long 40 mm wides, 10.5 millimeters thick in caudal furca socket both sides, back, be to be used for fixing and to adjust diameter 10 millimeter axletree positions (axletree adapter shaft skin and wheel).Will lay lock core on the axle center, the diameter of dead bolt, axle must surpass 10 millimeters these common-use sizes, and certain intensity will be arranged.

2, have reliability: the axle skin that bicycle connects wheel keeps original mounting structure constant, and the lockhole that is installed in the skin need be contained in the steel ball inboard and certain intensity is arranged, and could guarantee waterproof, the sensitivity, reliable of dead bolt, lockhole transmission device.

3, has safe and practical property: the safety assurance of axletree lock and the convenience that locks.

Summary of the invention

The purpose of this utility model: a kind of general installation dimension that does not change caudal furca socket and axle skin behind the existing bicycle is provided, is implemented in the method that locks between axletree and the skin.The axle intracutaneous cover that contains the dead bolt hole clipping embeds from axle intracutaneous side, and the axletree that contains dead bolt under the locking states can not be extracted, and bicycle is in a single day stolen, can only change a skin and axletree again, and the pilferage purpose can not be reached.

The technical solution adopted in the utility model:

The thick side of axletree one side is thin; lock core is contained in thick axle spindle nose one end; two grooves are by the standard tail prong of bicycle up and down to utilize thick axle, and cross-sectional plane protection dead bolt universal driving shaft hole can make lock core, dead bolt realize adding and be locked in back axle near lock core side shaft skin middle bearing inboard in the groove.The axle intracutaneous cover that contains the dead bolt hole clipping embeds from axle intracutaneous side, and the axletree that contains dead bolt under the locking states can not be extracted.The insurance Metallic card protection axletree lock and the vehicle frame caudal furca socket in the axletree outside.Nut waterproof shaft-cup protection key keyhole.Add the locking bit mark, conveniently lock.

1,, only changes a side of axletree and axle skin at commonality.It is 20 millimeter that one end of spindle nose is increased to diameter, prolongs the axle horizontal center line and makes a call to that a macropore is placed lock core and an aperture is placed the lock core universal driving shaft.Growing 5 millimeters intersections of 40 mm wides, 10.5 millimeters thick with bicycle caudal furca socket, the both sides up and down of axle are milled out two wide grooves of 8 millimeters just in time insert caudal furca, stay thick 10 millimeters of wide 20 millimeter of diameter, the centre just in time allows the aperture of diameter 6 millimeter pass through, aperture communicates with 6 millimeters vertical dead bolt holes of diameter on the axle in the bearing inboard by bearings mounted 15 mm dias.Caudal furca socket junction is by cross section 78.5 square millimeters of 10 millimeters of original diameters, and becoming the thick 10 millimeters cross section of wide 20 millimeters * (deducting 6 millimeters centre hole 28.26 square millimeters of diameter) 170 square millimeter intensity has increased, and the radius of axletree has only increased by 5 millimeters.

2, at reliability, replace ball with bearing, the axle skin side that locks is replaced axle bowl, steel ball, the axle bumper of primitive axis intracutaneous with 6002 bearings (15 millimeters of 32 millimeters internal diameters of external diameter), and an axle skin opposite side need not be changed the direct replacement of available 201 bearings (10 millimeters of 30 millimeters internal diameters of external diameter).The axle skin is made up of interior nested structure, and rectangular distribution 4-6 dead bolt knock hole embeds from axle intracutaneous side above the interior cover, in the key that puts make a skin become integral body with keyway on the skin.It is constant substantially that axle intracutaneous side direction wheel center is widened 10 millimeters (wherein 7 millimeters are used to keep original connection structure) axle skin outward appearance.

3, at safe and practical property, the insurance Metallic card in the axletree outside is selected 2.5 millimeters iron plate punch formings for use, 40 millimeters of long 36 mm wides, and wide both sides up and down have and curve 5 millimeters right angle, and the slotted hole of 10 millimeters of long 28 mm wides is left in the centre.Insert a thick axle groove during installation and be buckled in cycle frame caudal furca socket up and down on two socket supports, the safety of protection vehicle frame and Shaft center lock.Normal has used the effect of protection vehicle frame caudal furca socket, by two the square edges distortion up and down of metal insurance card, axletree breaks away along the tailing axle socket during improper destruction, and wheel and one side vehicle frame are close to wheel can not be rotated.Add locking bit mark 4-6 and be stuck on the spoke bar cap consistently by what the colored plastic part was made, conveniently lock with built-in dead bolt hole clipping orientation.Nut waterproof shaft-cup is by opening and closing the protection key keyhole.

The beneficial effects of the utility model are, inner structure is changed Xiao Yi and implemented, and materials used is few, improves the mechanical characteristics of bicycle simultaneously, can be directly and various bicycles exchanges.The sealing mode of operation of shaft lock unification and insurance Metallic card have been strengthened theftproof performance.Add the locking bit mark and conveniently lock, equally easy to maintenance under the unlocking condition with common car.
