Abstract

The utility model relates to a head lock for motorcycles and electric vehicles, which comprises a lock body, a lock cylinder, an inner core, a key, a lock shaft, a cylindrical fastener, a small spring, a small plug, a big spring and a positioning pin, the outer side of the lock cylinder is provided with a guide tooth and a guide positioning tooth, which are matched with a slide way in a lock hole, so that the lock cylinder can move to the left and the right in the lock hole but cannot rotate, and the lock body is provided with a positioning hole. After the lock cylinder is mounted into the lock hole, the positioning pin is inserted into the positioning hole of the lock body, and when the lock cylinder moves to the right for a certain distance under the action of the tensile force of the big spring, the guide positioning tooth is blocked by the positioning pin, so that the lock cylinder cannot move to the right further, and therefore the lock cylinder is positioned. The utility model has the advantages of simple structure, convenient unlocking and lock and good anti-theft property, and is applicable to the anti-theft devices of various motorcycles and electric vehicles.

Description

A kind of motorcycle, electric motor car headstock lock

Technical field

The utility model relates to a kind of motorcycle, electronic lock, refers in particular to the motorcycle, the electric motor car headstock lock that directly are fixed on motorcycle, the electric motor car headstock.

Background technology

Known motorcycle, electronic lock are switch band head locks, and this lock is opened by technology unlocking and violence easily by force owing to the defective that exists simple in structure.

Summary of the invention

In order to overcome the defective of existing motorcycle, electronic lock, the invention provides a kind of structural integrity, difficult motorcycle, electric motor car headstock lock are opened in technology unlocking and violence.

The technical scheme that its technical problem that solves the utility model adopts is: motorcycle, electric motor car headstock lock comprise: lock body, lock core, inner core, key, lock shaft, cylinder buckle, little spring, little sprue, big spring, alignment pin.There are a guiding tooth and a guide-localization tooth in the lock core outside, matches with chute in the lockhole, makes lock core move left and right in lockhole, but can not rotate.One locating hole is arranged on the lock body, in lock core is installed into lockhole after, alignment pin inserts in the lock body locating hole, when lock core behind the certain distance that moves right under the effect of big spring tension force, the guide-localization tooth pin that is positioned blocks, lock core can not be turned right moving again, plays the role of positioning.One locked groove vertical with the lock shaft direction arranged on the lock shaft, lock shaft hole inwall has a last pellet shot from a slingshot hole, after in little spring, the cylinder card spiral-lock hand-hole, block little spring with little sprue, after lock shaft is moved to the left certain distance, cylinder card is buckled in the locked groove that slips under the effect of little spring tension force on the lock shaft, and lock shaft is stuck can not move left and right, reaches the locking purpose.Lock body divides T shape and two kinds of structures of U-shaped, and U type opening two end internal diameters equal motorcycle, electric motor car front fork outer shaft diameter.Two screw holes are established at U type opening two ends, and are corresponding with two screw holes of lock on the fixed block, and fixed block is directly fixing or be welded on the front fork outer shaft.U-shape lock body and fixed block are just in time embraced the front fork outer shaft after fixing by two fixed screws.Axle respectively has a lockhole that size is identical with a side of outer shaft in the front fork, when axle in the front fork turn an angle and the front fork outer shaft on lockhole when overlapping, lock shaft can enter in two lockholes, outer shaft is blocked by lock shaft in making, and makes in the front fork axle can not do the direction rotation.(screw hole is respectively established at the two ends of T shape lock body, directly with motorcycle, the preceding fork shaft fixed block of electric motor car on two screw holes fix with screw.T shape lock body internal construction is identical with U-shaped lock body internal construction.)

The beneficial effects of the utility model are: by locked groove, settings such as big spring open and close flexibly lock.Lock body U-shaped structure theftproof is good, and when lock was in blocking, even the fixed screw of dismounting U-shaped lock body two ends, lock also can't take out.

The specific embodiment

Installation process, lock shaft 24 is inserted in big spring 7 in Fig. 2, on the lock core 9 two guiding teeth 10,11 are aimed in the lockhole 16 of packing into behind lockholes 16 chutes 15, alignment pin 5 insertion locating holes 6 pass from two guiding teeth 10,11 centres on the lock core 9 in Fig. 1, guide-localization tooth 10 pin 5 that is positioned blocks under the effect of big spring 7 tension force, can not be toward moving right.After cylinder buckle 1, little spring 2 are packed in the pellet shot from a slingshot hole 4, block with little sprue 3 and to seal the head lock installation.

U-shaped lock body 22 installs and fixes with vehicle frame: fixed block 14 is welded on the front fork outer shaft 21, and U-shaped lock body 22 openings simultaneously are inserted in car front fork outer shaft 21, and the screw hole 23 on opening two ends overlaps with screw hole 13 on fixed block two limits, fixes with screw.

T shape lock body 25 installs and fixes with vehicle frame: fixed block 27 is welded on the front fork outer shaft 21, and two screw holes 26 of T shape lock body one end overlap with two screw holes 25 on the fixed block 27, fix with screw.

Use, in Fig. 4, lock core 9 is moved to the left under external force, and big spring 7 is compressed, and lock core 9 drives lock shaft 24 and is moved to the left together, after moving a certain distance, cylinder buckles 1 in the lock marble hole 4 slip in the locked groove 8 on the lock 24, and lock shaft 24 is stuck, can not move left and right, lock shaft 24 also enters in the lockhole 20 after axle 19 outer shafts 21 overlap in the front fork simultaneously, and this moment, Fig. 5 was a blocking.

In Fig. 5, when blocking, insertion key 18 rotational lock cores 9 of unblanking, lock core 9 drive lock shafts 24 and rotates together, and the rotation afterwards cylinder buckle 1 on the locked groove 8 skids off outside the locked groove 8, pellet shot from a slingshot buckle 1 is pressed in the pellet shot from a slingshot hole 4 by lock shaft, lock core 9 is repositioned to Fig. 4 position under the effect of big spring 7 tension force, after key 18 drives lock core 9 rotation returns, extract key 18, be unlocking condition (as Fig. 4).
