Description

A kind of axletree lock

Technical field

This practical anti-theft column lock that relates to a kind of bicycle, battery-driven car, motor bike exactly is a kind of axletree lock.

Technical background

Current, the anti-theft column lock of bicycle, battery-driven car, motor bike mainly contains disc lock, little U-shape lock, cable-type padlock, chain lock and large U type lock.Disc lock is carefully easily pounded to be out of shape by sled because of the thin beam of iron sheet to be opened; Little U-shape lock, cable-type padlock, chain lock have no preventive effect to the wire nipper of car thief; The tapered end of large U type lock can be shaken easily with the connecting pin of locking pipe and cause tapered end to be dislocated.So be difficult to really play antitheft effect.

The utility model content

The utility model purpose is at existing defective, provide a kind of axle of bicycle, battery-driven car, motor bike that not only can utilize to do lock body and tapered end to people, the control dead bolt moves in wheel hub, thereby vehicle is pinned in the rotation of control wheel hub, prevent that effectively car thief from utilizing instruments such as reinforced shear, wire nipper, crowbar to prize, twist, cut the lock, and novel, rational in infrastructure, economical and practical axletree lock.

The utility model comprises tapered end, lock core and lock body, it is characterized in that: lock core places in the lock body, and tapered end and lock body connect into a complete axletree.

Lock core, folding bolt, roller, pin, returning spring and nut are housed in the lock body from left to right successively, and the folding bolt is rotated with in lock body by screw thread, and pin passes roller, and two ends is embedded in " one " font caulking groove that has on the lock body inwall.

The cylinder-shaped end of lock core connecting strap is fixedly connected on ball lock head by snap ring, and band steel shape end is plugged in " one " font groove on the folding bolt.

When installing and using, oil sealing, axle bumper, steel ball holder, steel ball are formed the two ends that two antifriction-bearing boxs are installed in wheelboss inner hole respectively, be sleeved on outside the axletree lock, on wheelboss inner hole, open a circular groove and a pair of axial groove simultaneously.Again key is inserted the open keyhole on the tapered end, during unlatching, cw turns key, make the lock core clickwise, drive folding bolt clickwise and move right, compressing roller and pin move right along " one " font caulking groove on the lock body, when the key cw is screwed to the motionless position of commentaries on classics, pin just in time moves to " one " font caulking groove right-hand member, returns stubborn key to the tapered end latched position, extracts key.At this moment, pin is positioned at the circular groove position that wheelboss inner hole is opened, and wheel hub is free to rotate around lock body; When sealed, conter clockwise turns key, make the lock core left-hand revolution, drive folding bolt left-hand revolution and be moved to the left, roller and pin are moved to the left at " one " font caulking groove on the lock body under the effect of returning spring restoring force, and the circular groove position that the two ends of pin are opened by wheelboss inner hole enters the axial groove that wheelboss inner hole is opened left, when the key conter clockwise is screwed to the motionless position of commentaries on classics, pin moves to low order end, returns stubborn key to the tapered end latched position, extracts key.At this moment, pin is positioned at the axial groove position that wheelboss inner hole is opened, and wheel hub can not rotate with respect to lock body.Thereby play the effect of locking wheel.

Effect of the present utility model

1, the utility model utilizes the axle of bicycle, battery-driven car, motor bike to do lock body and tapered end, the control dead bolt moves in wheel hub, thereby vehicle is pinned in the rotation of control wheel hub, prevents that effectively car thief from utilizing instruments such as reinforced shear, wire nipper, crowbar to prize, twist, cut the lock.

2, the utility model is novel, rational in infrastructure, economical and practical, is beneficial to extensive popularization.
