Description
Technical field
The utility model relates to the direction locking that a kind of bicycle, motor bike and three-wheel vehicle are waited for bus.
Background technology
The lock that uses at present, the installation position is low, must bend over or squat down during operation, and particularly the elderly is more inconvenient, and anti-theft is poor.Change lock and leave no trace, stolen vehicle transaction is spread unchecked.
Summary of the invention
Again designing car lock pin structure and installation position, changing the locking wheel is locking direction, is installed on vehicle frame and front fork joint portion, and the position height is convenient to operate, and theftproof performance is good.The lockset pick-proof is anti-to be cut, as is destroyed, and can on vehicle frame, stay significantly vestige permanently, and the stolen back of vehicle foul is difficult to sell.
The present invention realizes content:
1, bicycle theft-prevention direction lock is made up of idle-run lock pin (1), lock core cover (2), lock cylinder (8), spring (5), pellet shot from a slingshot hole group (3) and (4), dead bolt (7), locating dowel pin (9), lock body (11) and key, pellet shot from a slingshot etc.; Lockset is positioned at vehicle frame head pipe position, with locking front fork (12).
2, lock body (11) is welded on the vehicle frame head pipe (13), and lock core cover (2) is welded in the lock body (11).
3, set up two groups of pellet shot from a slingshot hole groups (3) and (4) separately on the lock core cover (2), two groups of pellet shot from a slingshot holes on lock core cover (2) vertically, radially all be in staggered distribution.
4, lock core partly is made up of idle-run lock pin (1) and lock cylinder (8) two, and idle-run lock pin does not shoot son.
Description of drawings:
Fig. 1 is a bicycle theft-prevention direction lock assembly.Wherein in pellet shot from a slingshot hole group (3) and (4), the pellet shot from a slingshot hole number is decided according to the lock size; Lock core marble does not mark; Locating dowel pin (9) is not dead with sealing point (10) weldering, repairs so that change.
Fig. 2 is a bicycle theft-prevention direction lock assembly drowing.Wherein sealing point (10) quantity is decided according to the lock size; Lock body (11) inside diameter D 1 is a running-fit with lock core cover (2).
Fig. 3 is a bicycle theft-prevention direction lock installation portion bitmap.Lock body is welded in vehicle frame head pipe (13) left side or right side, and is placed in the middle up and down.
The specific embodiment:
1, lock body (11) is welded on the vehicle frame head pipe (13), and dead bolt (7) is used to control the interaction of vehicle frame head pipe (13) and front fork tube (12), and then locking car direction.
2, lock core cover (2) is welded in the lock body (11), except that replacing left by brill, and manual non-exchange lockset.
3, the isometry position after vehicle frame head pipe (13) and front fork tube (12) cooperation is established the hole, and the aperture is greater than dead bolt (7) diameter.The radial position in two holes is on handlebar and the vehicle frame coaxial line when angled.
4, lock core is for can move vertically, and is divided into idling core (1) and lock cylinder (8) two parts.Idling core (1) does not shoot son, can only dally.(1) and (8) two lock cores pack into behind the lock core cover (2), fixing with screw (6).
5, on lock core cover (2), set up (4) two groups of pellet shot from a slingshot holes of pellet shot from a slingshot hole group (3) and pellet shot from a slingshot hole group separately, two groups of pellets shot from a slingshot along lock core cover (2) axially, radially all be in staggered distribution.The pellet shot from a slingshot hole group (4) of lock cylinder (8) pellet shot from a slingshot under unlocking condition and on the lock core cover (2) aligns; The pellet shot from a slingshot of lock cylinder (8) and pellet shot from a slingshot hole group (4) is staggered, and pellet shot from a slingshot is no longer staggered after inserting key, pushes vertically and rotates; Pellet shot from a slingshot and pellet shot from a slingshot hole group (3) on the lock cylinder (8) are aligned; Lock cylinder (8) is staggered with the pellet shot from a slingshot on the pellet shot from a slingshot hole group (3), and key is extracted smoothly, makes lock be in the strong attitude of locking.At this moment, dead bolt (7) stretches out vehicle frame head pipe (13) and gets into front fork tube (12), and the car direction is locked.
When 6, unblanking; The key counter-rotating; Under spring (5) effect, dead bolt (7) and idle-run lock pin (1), lock cylinder (8) return to the initial position vertically, and vehicle frame head pipe (13) loses the interspersed locking of dead bolt (7) with front fork tube (12) and separates; Make vehicle frame and front fork recover to produce relative active state, the direction lock is opened.
