At present, anti-theft lock for motorcycle has of all kinds, for example patent 98245972.6 anti-theft lock for motorcycle, patent 01203352.9 anti-theft lock for motorcycle, patent 01231183.9 theftproof lock etc., structure is complicated, some need rotate 10 multi-turns could lock the jail, rotates 10 multi-turns certainly again and could open, and uses and feels to bother very much, special time-consuming, so be difficult to promote the use of.
Technology contents
The purpose of this utility model provides a kind of anti-theft lock for motorcycle, and by hinge, pin connects and nut is buckled in the pre-tightening of spring, spring pretension orientation buckles screw pin surely and lock core, drilling-preventing structure combine, locking is firm.
The utility model is made up of lock bridge and lock body; lock bridge (1) is the U font; one end and strip lock body (2); hinge (3) connects; one end of lock body (2) is equipped with drilling-preventing structure (7); drilling-preventing structure (7) is by anti-drilling sheet (8); anti-drilling sheet over cap (9) is formed; drilling-preventing structure (7) is pressed on the lock core (6); lock core (6) is buckled nut (5) with the pre-tightening of spring; spring pretension orientation is buckled screw pin (4) surely and is connected; spring pretension orientation is buckled screw pin (4) surely and is connected with an end of lock bridge (1), buckles nut (5) and spring pretension orientation in the pre-tightening of spring and buckles surely between the screw pin (4) and be provided with spring.
The utility model is reasonable in design, and is simple in structure, can guarantee the lock rotation freely, can screw smoothly or withdraw from, should promote the use of.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model pin connects schematic diagram;
Fig. 3 is the utility model cross lock view;
Fig. 4 is the utility model one letter lock view.
The specific embodiment
As shown in Figure 1, lock bridge and lock body high-quality steel, stainless steel manufacturing.One end of lock bridge connects with lock body by hinge, and as shown in Figure 2, lock bridge one end has pin-and-hole to connect with the pin on the lock body is metastable.Lock body is by drilling-preventing structure, anti-theft lock control, and there is the pre-tightening of spring to buckle that nut, spring pretension orientation are buckled screw pin surely, spring cooperates, when the lock bridge enters the precalculated position, clockwise rotate key, the lock core rotating nut, drive directed screw pin and travel forward, and enter pin-and-hole, lock skillful craftsman's function that bridge and lock body are combined to form closed loop, play locking this moment.When being locked in latched position, rotate counterclockwise key, the lock core rotating nut drives directed screw pin and withdraws from lockhole smoothly, and this moment locks bridge and lock body becomes open loop and loses locking function.Shown in Fig. 3,4, drilling-preventing structure can connect with a cross lock or a letter lock.
