Description

Theft-proof lock for motor cycle

The utility model relates to a kind of vehicle lock, particularly anti-theft lock for motorcycle.

At present, establishing by cable that motorcycle uses shuts and the direction lock, has the shortcoming of anti-theft capability difference.On April 10th, 1993, the anti-theft lock for motorcycle of a kind of application number for " 922389063 " authorized by Chinese Patent Office, this lock construction is comparatively simple, it is light, flexible that lock bridge is shifted one's position, azimuth design has mutually perpendicular two base plates under the lock body of this lock, and the one base plate is provided with the hidden bolt that can not arbitrarily dismantle.If the user need change this lock, in the time of must being opening lock bridge is evacuated to and turns an angle, when making long arc groove in the rotating shaft with bolt hole maintenance plumbness, this bolt just can be presented on the external world, and is promptly detachable.That is to say: when this was locked in locking or unlatching, bolt head was in hidden state all the time, can't take apart.But this is latched in following deficiency: 1, when lock is opened, must take out with hand, the zip beam, when being evacuated to the stopper slot place, after 90 ° of rotating shaft rotations, artificially the U-shaped lock bridge is inserted two holes on another base plate again, press lock bridge at last, lock bridge and motorcycle pillar ability keeping parallelism state, could drive a vehicle this moment, so use cumbersome, inconvenient.Though 2, not readily removable from facts have proved hidden bolt, it is meant that bolt head is in hidden state, the hitching post junction is to be exposed to the external world, as long as with the instrument hitching post that reverses, or directly destroys hitching post, and the theftproof performance of this lock just greatly weakens, and sees accompanying drawing 1.

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of easy to use, lock bridge can withdraw from automatically, rotate automatically, location automatically, the more reliable anti-theft lock for motorcycle of rational in infrastructure, theftproof performance.

The design scheme of the utility model anti-theft lock for motorcycle is such: this lock is formed rectangular anti-theft lock for motorcycle by parts such as lock body, latch plate, lock bridge, rotating shafts.It is characterized in that the lock core design is on latch plate; Lock body and latch plate corresponding section are respectively equipped with two through holes that can allow lock bridge pass through, and two holes on the lock body are the semicircle orifice of lower opening.Be connected with two rotating shafts on the corresponding lock body of semicircle orifice, the U-shaped lock bridge passes the two through hole on two shaft holes, semicircle orifice and the latch plate respectively, lock is lock-out state this moment.The U-shaped lock bridge is that L shaped lock bridge is fixedlyed connected as a whole with locking bar.In the junction of lock bridge and locking bar, be provided with an automatic drawing-out mechanism of forming by spring and link stopper; In lock body and the corresponding rotational position of another rotating shaft, also be provided with an automatic positioning equipment, when lock core was opened, the U-shaped lock bridge can withdraw from latch plate automatically, and rotated 90 ° automatically, located automatically then.

Now be described in detail as follows to the utility model anti-theft lock for motorcycle in conjunction with the accompanying drawings:

The utility model anti-theft lock for motorcycle is made up of latch plate 1, lock body 2, U-shaped lock bridge, rotating shaft 5,6, and lock core 9 is to be fixedly mounted on the latch plate 1 by pin 12, bolt 23.The U-shaped lock bridge is to be connected to become integral body by L shaped lock bridge 3 and locking bar 4 by steady pin 7, and the skin in the junction is provided with a gum cover pipe 8, also is provided with in the junction when lock core 9 is opened, and the U-shaped lock bridge can withdraw from the mechanism of latch plate 1 automatically.This mechanism is made up of link stopper 21, spring 20.Locking bar 4 is to offer an elongated slot 25 that communicates with endoporus one side on a thick walled steel tube, the pipe, link stopper 21 1 ends are fixed in the rotating shaft 5, and the other end inserts in the elongated slot 25 simultaneously, and spring 20 places pipe right-hand member in the locking bar 4, when this lock is lock-out state, 20 one-tenth compressive states of spring; When lock was opened, spring 20 restored to the original state.Rotating shaft 5 is provided with a torsion spring 22 with lock body 2 equipped positions; Rotating shaft 6 and lock body 2 relative rotation positions are provided with a detent mechanism; This mechanism is made up of push rod 19, spring 18 and push rod 17.Spring 18 and push rod 17 are installed on the lock body 2, and push rod 19 designs are in rotating shaft 6, and its two rod axis equates that with the pivot center distance of lock body 2 when lock-out state, push rod 19 axis and push rod 17 axis are spent at an angle of 90 from rotating shaft 6.

When lock is opening: when the U-shaped lock bridge has just withdrawed from latch plate 1, be rotated down because of the action of gravity of U-shaped lock bridge on the one hand; Below the effect of torsion spring 22 and lock body 2 two ends, be provided with the reason of two semicircle orifices of opening on the other hand, the U-shaped lock bridge is rotated down at once automatically, when rotating to 90 ° of positions, 19 one-tenth same axis of push rod 17 and push rod, push rod 17 promptly partly enter in the hole of push rod 19 under the effect of spring 18, rotating shaft 6 again can not be rotated thus, the U-shaped lock bridge reaches the purpose of location, U-shaped lock bridge and motorcycle pillar keeping parallelism state, and can drive a vehicle this moment.When stopping, only with hand push rod 19 is pinned slightly, and the U-shaped lock bridge is upwards rotated, change some positions slightly, push rod 19 is just return the original place, and rotating shaft 6 is rotatable.When the U-shaped lock bridge upwards rotated and inserts latch plate 1, dead bolt 10 entered the positioning port on the locking bar 4, and this lock is lock-out state.If someone destroys gum cover pipe 8 and steady pin 7, even extracted L shaped lock bridge 3 out, but locking bar 4 is to extract out, this lock still is lock-out state, and Here it is should the strong place of lock theftproof performance.

This anti-theft lock for motorcycle is rational in infrastructure, and easy to use, lock bridge is realized withdrawing from automatically, rotates automatically, located automatically, and the more reliable anti-theft lock for motorcycle of theftproof performance is worth extensive use.
