Abstract

The utility model relates to a transverse latch type bicycle lock. A lock assembly has the structure that an axial lug boss of a locking head is formed in the radial direction of a locking head and a groove which can hold the lug boss of a locking head in axial direction is formed in the radial direction of a lock core hole of a lock body; after the locking head is assembled with other components, the components are sheathed in the lock core hole and the groove from the back side of the lock body; the components are fixed on the lock body by a pin of a locking head; when the locking head pin is dug out, the locking head is still positioned in the lock body and a pin rod is continuously locked; therefore, locking the bicycle with the transverse latch type bicycle lock is reliable and safe.

Description

The cross latch type bicycle lock

The utility model relates to a kind of cross latch type bicycle lock.

The cross latch type bicycle lock is a kind of bicycle lock that came into vogue in recent years, because of its locking bar becomes horizontal door bolt shape, can design pole must be thicker, more additional again other measures, make the safety feature of this lock want high more than other bicycle lock, because of the popularization than this lock very fast.But, still also there is defective in this being locked in the design, the tapered end that mainly is the suit lock core is to put into the lock core hole of lock body from the front of lock body, then by tapered end being fixed on the lock core hole from the outside tapered end pin of putting into of lock body (end a screw or end a pinning), therefore in a single day end a screw or end a pinning and be removed, tapered end can be pulled out from lock body easily together with lock core, and bicycle lock has also just lost effect.

The purpose of this utility model provides a kind of cross latch type bicycle lock that locks reliable insurance.

Solution of the present utility model is that the radial direction at the cylindrical tapered end in tapered end upper edge forms the tapered end boss of axial trend and the groove that can hold the tapered end boss that the radial direction in cylindrical tapered end hole, lock body upper edge forms axial trend.

Illustrate particular content of the present utility model below in conjunction with drawings and Examples.

Fig. 1: elevation of the present utility model;

Fig. 2: the assembling drawing of tapered end and lock body;

Fig. 3: the A-A drawing in side sectional elevation of lock body;

As shown in the figure, cross latch type bicycle lock described in the utility model comprises the lock body assembly, locking bar assembly and jam plate assembly three parts, wherein the lock body assembly is by lock body 1, tapered end 2, lock core 3, lock core pin 4, lock core reduction torsion spring 5, lock core marble 6, marble pressuring spring 7 and tapered end pin 8 are formed, the locking bar assembly is by locking bar 9, locking bar case 10, locking bar back-moving spring 11, case bolster 12 and case reduction torsion spring 13 are formed, the utility model has adopted following feature in the design of tapered end 2 and lock body 1: the tapered end boss 14 that forms axial trend in the radial direction of cylindrical tapered end 2, cylindrical tapered end hole, lock body 1 upper edge 15 radially aspect form the groove that can hold tapered end boss 14 16 of axial trend, for this design, can be with lock core pin 4, lock core marble 6, marble pressuring spring 7 members such as grade all are arranged in each corresponding hole in the tapered end boss 14.8 insertions of tapered end pin are located in the pin-and-hole of tapered end boss 14 sides.

After the cross latch type bicycle lock had adopted the lock body assembly of said structure, tapered end was that the back from lock body packs into lock core hole and groove, if the tapered end pin is dug out from the outside, tapered end still is in the lock body so, and continue the locking pin rod, and therefore, more reliably insurance of this cross latch type bicycle lock locking.

Claims

1. cross latch type bicycle lock, comprise lock body assembly, locking bar assembly and jam plate assembly, wherein the lock body assembly is made up of lock body, tapered end, lock core, lock core angle, pin core reduction torsion spring, pin core pellet shot from a slingshot, marble pressuring spring and tapered end pin, and it is characterized in that: the radial direction at the cylindrical tapered end in tapered end (2) upper edge (2) forms the tapered end boss (14) of axial trend and the groove that can hold tapered end boss (14) (16) that the radial direction in cylindrical tapered end hole, lock body (1) upper edge (15) forms axial trend.
