Description

Steering lock

Technical field the utility model relates to a kind of steering lock, particularly a kind of steering lock with good pick-proof performance.

Background technology is present, in the prior art, " the recessive anti-theft column lock of bicycle " that a kind of patent No. 99243889.6 is arranged, lock is installed in the vertical tube of front fork of bicycle, recessed race is arranged on the core external cylindrical surface, being fixed on cam pin on the lock body is inserted in the recessed race on the core, the anglec of rotation of the recessed race on the core and helical pitch are limiting the distance that core advances and the angle of rotation, lock Che Shiyong key screws out core in lock body, the core that is positioned on the lock body with the location pellet shot from a slingshot crosses vertical tube of front fork and preceding connecting leg, vertical tube of front fork and preceding connecting leg can not be relatively rotated, two shock resistance pellets shot from a slingshot are arranged at core stroke not-go-end.This type of steering lock has certain disguise, but its " ten " word or " one " letter lock heart become and turn the fulcrum that a spanner utilizes lever principle to commit theft.

The summary of the invention the purpose of this utility model is exactly in order to improve the deficiency of above-mentioned steering lock, to design a kind of new steering lock, reaching theft-proof purpose.

The technical solution of the utility model is: the steering lock in a kind of vertical tube of front fork that is installed under bicycle, motor bike or the vehicle steering, steering lock belongs to spring lock, is made up of lock body, core, key, spring and pellet shot from a slingshot.Lock body is a cylindrical structural, core is columnar structured, columnar structured endoporus is a key hole, a pin is arranged in the key hole of core, key is played the role of positioning, an also available groove plays the role of positioning to key in the key hole of core, recessed screw thread or the recessed race of taking turns arranged on the core external cylindrical surface, be fixed on cam screw thread on the lock body or cam pin and be inserted in recessed the wheel in screw thread or the recessed race on the core, recessed on the core taken turns the anglec of rotation of screw thread or recessed race and helical pitch and limited the distance that core advances and the angle of rotation.Knock hole is arranged on the lock body, positioning groove is arranged on the core, knock hole, positioning groove and pellet shot from a slingshot are formed one group of location pellet shot from a slingshot, and this location pellet shot from a slingshot is limited in core between the core stroke 2mm-10mm, core is traveling under the key effect crosses desired position in vertical tube of front fork, preceding connecting leg and the lock body.Steering lock is installed in the vertical tube of front fork under bicycle, motor bike or the vehicle steering, respectively have a lock core hole in the core position of vertical tube of front fork and preceding connecting leg, lock Che Shiyong key screws out core in lock body, the core that is fixed on the lock body crosses vertical tube of front fork and preceding connecting leg, vertical tube of front fork and preceding connecting leg can not be relatively rotated, thereby the direction of control tap or bearing circle reaches theft-proof purpose; With key core is screwed in position in the vertical tube of front fork when unblanking, tap or bearing circle are free to rotate.

The beneficial effects of the utility model are, the utility model and core thereof are applicable to the direction lock of manufacturing various steering locks, particularly bicycle, motor bike, automobile and since the structure of this steering lock have be difficult for by sled bad, thereby strengthened anti-theft effect.

Description of drawings is described in further detail the utility model below in conjunction with the drawings and specific embodiments.
