Description

The Electrical Bicycle theftproof drum brake lock

Technical field

The utility model relates to a kind of lock, particularly a kind of and the anti-theft lock for vehicle that mechanism becomes one of stopping that rises.

Background technology

At present, the lock that Electrical Bicycle uses is various in style, but cuts both ways, and what have is simple to operate, but theftproof performance is poor, and the theftproof performance that has is good, but complex operation or very heavy.On the market now Band-type brake locks that adopt more, this lock construction is simple, the pick-proof performance is good, but also exists weak point: the one, noise is big during brake, and brake rubber block weares and teares easily, and the strap of the brake ruptures easily; The 2nd, Band-type brake lock is installed inconvenience, and lockset position of coupler usually can be blocked by vehicle frame and cover plate, causes the Electrical Bicycle of most of style not install and use.

Summary of the invention

For overcoming the above-mentioned disadvantage that existing Electrical Bicycle Band-type brake lock exists, problem to be solved in the utility model provides a kind of simple and reasonable, safe and reliable, pick-proof and braking quality is good, applied widely, noise is little Electrical Bicycle theftproof drum brake lock.The technical scheme that its technical matters that solves the utility model adopts, it comprises body skin, locking closure, the dish of stopping rises, shoe piece, rising stop the dish be fixed on the rear-wheel hub, body skin is fixed on the hind axle, shoe piece be arranged in the body skin by crank throw and with the dish coupling of stopping that rises, described rise stop the dish cylindrical be provided with lockhole, in the lock chamber of body skin and locking closure composition, be provided with lock body and link gear, link gear comprises linked block, trace and spring, one side of linked block is connected with the locking bar of lock body, opposite side is connected with trace, the other end of trace stretches out locking closure and corresponding with lockhole, the centre of trace is provided with chimb, and spring is arranged between the chimb and linked block of trace.Described lock body comprises outer lock shell, interior lock tube, lock core, locking bar, pull back spring, slide block, sliding block spring and key, outer lock shell is fixed on the body skin, internal lock is set in the outer lock shell, lock core is arranged in the interior lock tube, the end face of lock tube in locking bar is fixed on, the other end of locking bar stretches out outer lock shell and is connected with linked block, pull back spring is arranged on the locking bar between outer lock shell and the interior lock tube, the bottom surface of lock tube in slide block and sliding block spring are arranged on, the shift fork of lock core cooperates with slide block, and outer lock shell is provided with the knock hole that slide block cooperates.

In order to control the lock core anglec of rotation, internal lock puts the bayonet lock that is provided with the groove coupling of lock core.

In order to prevent that dust and muddy water from entering in the lock core, described outer lock shell is provided with cover of dust.

After adopting said structure, lock is connected as a single entity with the mechanism of stopping of rising, and has solved the problem that the Electrical Bicycle anti-theft column lock is difficult to install; By the key rotary locking cylinder, lock core drives slide block and cooperates with knock hole, and trace drives at locking bar, linked block and directly inserts the lockhole that rises and stop and coil, and interior lock tube and lock core integral body enter in the outer lock shell, so the pick-proof performance has obtained further reinforcement; Because the mechanism of stopping of rising is adopted in brake, braking quality has obtained further raising; Has simple and reasonable, safe and reliable, brake and the pick-proof performance is good, noise is little, advantage such as applied widely.

The specific embodiment

Illustrated in figures 1 and 2, specific embodiments for the utility model Electrical Bicycle theftproof drum brake lock, it comprises body skin 1, locking closure 4, the dish 12 of stopping rises, shoe piece 11, the rising dish of stopping 12 is fixed on the rear-wheel hub 15 of motor 18, body skin 1 is by pad 13, clamp nut 17 is fixed on the hind axle 16, shoe piece 11 be arranged in the body skin 1 by crank throw 14 and with dish 12 couplings of stopping that rise, described dish 12 the cylindrical of stopping of rising is provided with lockhole 9, lockhole 9 can be provided with a plurality of, in the lock chamber that body skin 1 and locking closure 4 are formed, be provided with lock body and link gear, link gear comprises linked block 7, trace 10 and spring 8, one side of linked block 7 is connected with the locking bar 6 of lock body by jump ring 5, opposite side is connected with trace 10 by jump ring 5, the other end of trace 10 stretches out locking closure 4 and corresponding with lockhole 9, the centre of trace 10 is provided with chimb, and spring 8 is arranged between the chimb and linked block 7 of trace 10.

Described lock body comprises outer lock shell 3, interior lock tube 20, lock core 21, locking bar 6, pull back spring 23, slide block 22, sliding block spring 24 and key 27, outer lock shell 20 is fixed on the body skin 1 by fixing jump ring 2, interior lock tube 20 is arranged in the outer lock shell 3, lock core 21 is arranged in the interior lock tube 3, the end face of lock tube 20 in locking bar 6 is fixed on, the other end of locking bar 6 stretches out outer lock shell 3 and is connected with linked block 7, pull back spring 23 is arranged on the locking bar 6 between outer lock shell 3 and the interior lock tube 20, the bottom surface of lock tube 20 in slide block 22 and sliding block spring 24 are arranged on, the shift fork of lock core 21 cooperates with slide block 22, and outer lock shell 3 is provided with the knock hole 26 that slide block 22 cooperates.Interior lock tube 20 can move at the inside and outside straight line of the chamber of outer lock shell 3.Lock tube 20 is provided with the bayonet lock 25 of control lock core 21 anglecs of rotation in described, and lock core 21 can rotate a certain angle in the interior lock tube 20.Described outer lock shell 3 is provided with cover of dust 19.

Working process of the present utility model is as follows: when locking, open cover of dust 19, inwardly promote lock core 21, lock tube 20 and locking bar 6 moved in the chamber of outer lock shell 3 in lock core 21 drove, when slide block 22 is aimed at knock hole 26, slide block 22 inserts knock hole 26 under sliding block spring 24 promotes, the lock body work of locking is finished; Meanwhile, locking bar 6 promotes linked block 7 moving linearly forward again, linked block 7 promotes spring 8, spring 8 drives trace 10 and moves, lock car process is divided into two kinds of situations, and first kind is that trace 10 is just aimed at lockhole 9, and trace 10 inserts lockhole 9, blocking rises stop the dish 12, rear-wheel hub 15 can not be rotated; Second kind is trace 10 mal-alignment lockholes 9, trace 10 contact afterwards slack with the dish 12 of stopping of rising, linked block 7 moves and compression spring 8 along trace 10, and need rotate rear-wheel hub 15 this moment gently, and rear-wheel hub 15 drives dish 12 rotations of stopping of rising, when trace 10 is aimed at lockhole 9, trace 10 inserts lockhole 9 automatically under the elastic force effect of spring 8, blocking rises stop the dish 12, rear-wheel hub 15 can not be rotated, thereby reach the purpose of lock car.

When unblanking, with key 27 rotational lock cores 21, the shift fork of lock core 21 overcomes and drives slide block 22 behind the elastic force of sliding block spring 24 and break away from and the cooperating of knock hole 26, under the elastic force effect of pull back spring 23, lock core 21 and interior lock tube 20 reset, and pulling linked block 7 and trace 10 disengaging lockholes 9, make rear-wheel hub 15 be in no arrested state, thus the purpose that realization is unblanked.
