CN2761772Y - Antitheft lock for motorcycle - Google Patents

Abstract

The utility model relates to an antitheft lock for motorcycles, which adopts the technical scheme that a key track slot is arranged along the direction of a key hole. The key track slot is perpendicular to a rectangular slot of a lock body, so that a key can be directly inserted into the lock hole along a track. A lock core tallies with the track but is not connected with the track, so that even if the track is destroyed, the lock core does not move, and the lock can not be opened, either. The lock core is directly installed in the utility model, and the lock core drives a lock catch to unlock the lock under the rotation of the key. When the key is pulled out, the lock catch automatically resets under the action of a spring and the trouble of pressing a transmission shaft for locking is saved.

Description

Anti-theft lock for motorcycle

The utility model relates to a kind of theftproof lock that curved key track is arranged.

There is a kind of theftproof lock to do case at present in order to make the robber directly insert keyhole with robber's turner tool, a common lock is closed, keyhole is hidden under steel plate, open the hole slot of a right angle type then in the position of keyhole, key is made a curved key, but also have following weak point: the inconvenience of 1, unblanking, particularly evening key are sometimes inserted and just can be inserted in the lockhole several times; 2, enclosed inside is the finished product lock, has caused unnecessary waste; Must press movable axis when 3, locking car could pin, and the utility model can overcome above weak point.

The purpose of this utility model is achieved in that along the direction of keyhole does a key rail groove, and coincides with the trough with straight angle of locking body, makes key directly insert lockhole along track.The lock stamen coincide with track but does not link to each other, and the destroyed lock stamen of track also can not moved, and lock is not still opened.The lock stamen is directly installed in the utility model the inside, drives under the rotation that latches in key lock is opened, and key is extracted under the effect of spring, and snap close automatically resets, and has saved and has pressed the power transmission shaft locking.

Owing to adopt such scheme, unblank, locking is safer, facility.

Below in conjunction with accompanying drawing the utility model is further specified:

Fig. 1 is the utility model principle assumption diagram;

Fig. 2 is the utility model key trajectory diagram;

Fig. 3 is the utility model lock cut-away view;

Fig. 4 is the utility model key track front end face figure;

Fig. 5 is the utility model key track rear end face figure;

Fig. 6 is the utility model Key structure figure;

Among the figure: (1), track body, (2), track, (3), inner orbit, (4), installation handle, (5), lock core, (6) torsion spring, (7), snap close, (8), lock bridge, (9), lock body, (10), curved key.The utility model embodiment 1: torsion spring and lock are installed on the lock core, and lock, embed in the lock body, track is packed in the lock body with pin.The installation handle of swing-around trajectory coincides the trough with straight angle on rail groove and the lock body, and aligns with the lock stamen keyhole of front, with the sulfonium nail lock core, track sulfonium jail is got final product on lock body then.

Claims (1)

1. theftproof lock that curved key track is arranged, it is characterized in that: it is to do a key rail groove along the direction of keyhole, and coincides with the trough with straight angle of lock body, latches under the effect of spring to automatically reset.
