Description

Foot anti-theft safety lock for bike

The utility model belongs to a kind of lockset of the bicycle that avoids theft.

Regular Bicycle often adopts the crab claw to lock the bicycle that avoids theft, this crab claw lock is that lock pin is installed in dull and stereotyped iron plate and the crab claw groove, be packed on the trailing wheel with rivet, the thief is as long as insert the bottle opener of wear down with one, can pry open, perhaps the thief also can promote the bicycle front-wheel to steal, so can not finely avoid theft as long as load onto hook on waist-belt.Also have a kind of chain type bicycle lock, it opens cumbersome, and breaks the bicycle surface lacquer easily, meet careless people and be eager by bike, at will carry and place, lose easily, also may be because the vibrations by bike the time, chain can fall and snap in wheel, causes the accident.

The purpose of this utility model is at above shortcoming, and a kind of foot-operated anti-theft safety lock is provided, and it adopts the built-in type screw that base and retainer ring are installed on the bicycle crotch pipe, and whole lock body embeds in the base.Lock core adopts plate armature, the lock pin employing " " shape elongated slot plate, as long as lock pin is pushed lock body, then lock pin is blocked by lock core; the lock pin head end passes the wheel steel wire ring, is stuck between the steel wire, and bicycle is locked; because lock housing is closed state; the event stealer is had no way of doing it, thus can play the burglary insurance effect preferably, simultaneously; because its adopts foot-operated or the hand mode of pressing opens and closes; thus very easy to use, can finish unlatching and locking a second, convenient and practical.

The utility model is done in such a way that this foot-operated anti-theft safety lock of design, is made up of lock housing, lock pin, lock core, retainer ring, base etc., is shaped on keyhole in the lock housing, and base and retainer ring adopt the built-in type screw to be installed on the bicycle crotch pipe.Whole lock body embeds in the base.Lock core is installed in the top of lock housing, and is corresponding with the keyhole of lock housing, is close to the lock core bottom lock pin is installed, and returning spring is contained in the interior returning spring position groove of lock pin.Lock core adopts plate armature, it is to be assembled by two sheet metals, technically lock core is taked 4 measures, the one, on every sheet metal, be shaped on some difformities and have the hole on the limit of linking closely, and corresponding limit, the hole flange that all is shaped on, the 2nd, between limit, the hole flange on two sheet metals, be buckled into one mutually, connect with stage clip again, wherein the protruding tongue of lock core is that limit, hole flange is made, and relatively rotates fulcrum between two sheet metals, also is that limit, hole flange fastens and forms.The 3rd, the link closely hole on limit of band on two sheet metals, its shape, position and distance are corresponding with shape, position and the distance of tooth in the key 1.The 4th, corresponding at the extension of limit, hole flange with the spacing of two sheet metals.Lock pin 3 be " " be shaped on block and the position groove and the protruding tongue bayonet socket of lock core of returning spring in the shape elongated slot plate.

Below in conjunction with embodiment shown in the drawings, the utility model structure is described further:

Fig. 1 is the utility model structural representation.

Fig. 2 is the lock core structure schematic diagram.

Fig. 3 is the detent configuration schematic diagram.

The 1-key, 2-lock housing, 3-lock pin, 4-base, the 5-spring washer, 6-hexagonal (hexagon)nut, 7-retainer ring, the 8-stage clip, 9-lock core, 9A-lock core metal sheet, another metal sheet of 9B-lock core, the protruding tongue of 10-lock core, 11-bicycle crotch pipe, the 12-returning spring, 121-returning spring position groove, 13-rear fender, the protruding tongue bayonet socket of 14-lock core, 15-link stopper, 16-fulcrum.

Shown in Fig. 1,2,3, during fabrication, two sheet metal 9A, 9B of lock housing 2, lock pin 3, base 4, retainer ring 7, lock core 9, rear fender 13 all adopts the sheet metal punch forming, and lock core 9 adopts plate armature, is to be dressed up by two sheet metal 9A, 9B, technically lock core 9 is taked 4 measures, the one, on every sheet metal, be shaped on some difformities as shown in Figure 2, and have the hole on the limit of linking closely, and corresponding limit, the hole flange of making.The 2nd, between limit, the hole flange on two sheet metal 9A, the 9B, be buckled into one mutually, connect with stage clip 8 again, wherein the protruding tongue 10 of lock core is that limit, hole flange is made, the fulcrum 16 that relatively rotates between two sheet metal 9A, the 9B also is that limit, hole flange fastens and forms.The 3rd, in two sheet metal 9A, 9B, be shaped on the hole of being with the limit of linking closely, its shape, position and distance are corresponding with shape, position and the distance of tooth in the key 1.The 4th, corresponding at the extension of limit, hole flange with the spacing of two sheet metal 9A, 9B.Lock pin 3 make " " shape elongated slot plate, be shaped on block 15 and the returning spring position groove 121 and the protruding tongue bayonet socket 14 of lock core of returning spring 12 in the frid.

Lock core 9 is installed in the top of lock housing 2, corresponding with the keyhole of lock housing 2.Be close to lock core 9 bottoms lock pin 3 is installed, returning spring 12 is contained in 121 grooves of returning spring in the lock pin 3, loads onto rear fender 13, makes 2 one-tenth closed states of lock housing.Adopt built-in type screw 6 to be installed on the bicycle crotch pipe 11 base 4 and retainer ring 7 earlier, then lock body is embedded in the base 4.

As long as key 1 is inserted in the lock body keyhole, foot-operated key or hand are pressed key, then the stage clip 8 on the lock core 9 changes the position of lock core 9B along the direction of arrow shown in Figure 2, returning spring 12 restores at once, lock pin 3 is thrown off lock cores 9 protruding tongues 10 and is just unhinderedly ejected automatically, and lock is just opened, simultaneously since the effect of stage clip 8 the tooth mouth of key is blocked, it can not lost, and cycle wheel just rolls freely.During parking, as long as lock pin 3 is pushed gently, also owing to the effect of returning spring 12, lock core 9 blocks lock pin 3, and lock pin 3 passes the cycle wheel wire loop simultaneously, and wheel can't be rotated, and reaches the purpose of locking.At this moment, key is desirable stays.

The utility model has the advantage of that this lockset adopts the built-in type screw that base 4 and retainer ring 7 are fixed on the bicycle crotch pipe 11, itself is closed state lock body, so stealer is had no way of doing it, can play preferably the burglary insurance effect, simultaneously, because it has adopted foot-operated or hand is pressed mode, so unlatching and locking are all very convenient, is a kind of convenient and practical anti-theft safety lock.
