Abstract

The utility model relates to a lock for a motorcycle, comprising a lock shell, two lock seats, two lock blocks, a lock core device, a push block, and a lock bolt rod, wherein, rotating the lock core by a key to drive the push block, and thereby, the two lock blocks abutted with a right and a left gaps are rotated to separate from clamping grooves of the lock bolt rod; the lock bolt rod is sprung away from a lock bolt hole by a compression spring arranged in the lock bolt hole of the lock seat, and the pushing end of the compression spring extends upwards to abut with the lock blocks in order to enable the lock blocks not to interfere the lock bolt hole through turning around; when the lock bolt rod is inserted into the lock bolt hole, the pushing end of the compression spring moves downwards due to the pressure to release the pushing to the lock blocks; a turning key enables the lock core to drive the push block, and thereby, the two lock blocks reset; a spring plate arranged on a containing groove of the lock seat pushes the lock blocks to clamp on a clamping groove of the lock bolt.

Description

Lock for motorcycle

The utility model relates to a kind of Lock for motorcycle, particularly a kind of can be with the bilateral snap close of lock bolt rod, make snap close more firm really, can prevent that more the burglar from prizing the Lock for motorcycle that opens.

Known Lock for motorcycle 1 as shown in Figure 1, 2, when it desires snap close, must earlier an end pin 11 oblique cuttings of U-shape sword iron 10 be gone in the oval lockhole 120 on the lock tube 12, and the draw-in groove 110 on the end pin 11 is embedded on the block bolt 13 of lock tube 12 1 ends, and other end pin 14 inserts in the round keyhole 121, again by key 15 rotation lock cores 16, make projection 17 rotations and drive the stop catch plate 18 past superior displacements that are arcuation, and the draw-in groove on the built-in end pin 14 140, so, U-shape sword iron 10 just can't be pulled out in the self-locking tube 12, and then reaches the purpose of snap close; When desiring to trip, by key 15 rotation lock cores 16, drive down homing of stop catch plate 18, again U-shape sword iron 10 is tilted, make the draw-in groove 110 on the end pin 11 throw off block bolt 13, tiltedly pull out U-shape sword iron 10 again, so promptly reach the purpose of triping, though yet the design of this known Lock for motorcycle 1 can combine the purpose of reaching snap close and triping with lock tube 12 for U-shape sword iron 10, still has following shortcoming on it uses:

1, during snap close, U-shape sword iron must be tilted insert in the lock tube, the draw-in groove on the end pin is embedded on the block bolt of lock tube one end.

2, U-shape sword iron must select correct draw-in groove direction to insert in the lock tube, can make block bolt and stop catch plate chimeric (because of the direction difference of draw-in groove on the two end pin, an end pin is located at left surface, and other end pin is then in place, the back side).

3, stop catch plate can only be with the monolateral snap close of end pin, and theftproof is not good.

When 4, triping, the very wide-angle that U-shape sword iron must be tilted can make draw-in groove break away from the block bolt, and is if limit by the space, extremely difficult with U-shape sword iron release lock tube the rib of tire (as be limited by).

In view of this, main purpose of the present utility model is to provide a kind of Lock for motorcycle, and it can be with the bilateral snap close of lock bolt rod, make snap close more firm really, can prevent from more that the burglar from prizing to open.
