Description

Bicycle for prevention of stealing

The utility model relates to a kind of bicycle, particularly a kind of self anti-theft bicycle with lock.

The bicycle of Xiao Shouing in the market, generally himself tool not with lock must add lock so that when not using bicycle is pinned for the purpose of antitheft.The lock that adds is varied, and its antitheft form is to pin bicycle rear it can not be rotated and to play antitheft effect mostly.This lock is because outside being exposed to fully, very easily the stolen car person smashes and car is stolen, or the stolen car person mentions trailing wheel bicycle is pushed away away.

The purpose of this utility model is to add lock at above-mentioned usefulness to pin the existing drawback of the theft-proof method of bicycle rear, manufacture and design a kind of self bicycle with lock, this bicycle can make handlebar and front-wheel be fixed on the position that becomes certain drift angle with the dead ahead, bicycle can not be advanced, promptly can not be ridden away or push away away and play antitheft effect.

The purpose of this utility model realizes by following proposal: be fixed with a lock housing on the three-pronged connector pipe of five cun tubes on the cycle frame and cant beam junction, the lock machine of a band clamp is equipped with in top in the lock housing, and the latch and the hairclipper of band retracing spring is equipped with in the below.Have the latch jack on five cun tubes in latch dead ahead.Bicycle car fork tube rotates 30 degree ┄, 60 degree backs to the left or to the right and also has a latch jack in the place over against five cun tube latch jacks.Like this, also have a latch jack when the place of the good pin jack of bicycle parking.Like this, after bicycle parking is good, when deflection 30 degree ┄ 60 degree make five cun latch jacks on the tube aim at latch jack on the cars fork tube to the left or to the right with handlebar, pressing hairclipper advances latch in two jacks, rotating key makes the clamp on the lock machine block the boss of latch rear end, extract key out, bicycle is promptly by the lock jail.

Below in conjunction with accompanying drawing the utility model is further elaborated.

Fig. 1 is the lock cutaway view on five cun tubes of the utility model anti-theft bicycle

Fig. 2 is the utility model anti-theft bicycle lock locking-in state cutaway view.

With reference to Fig. 1, five cun tubes (1) are equipped with lock housing (3) with cant beam (2) junction, and lock machine (4) is equipped with in the top in the interior space of lock housing (3), and there is clamp (5) rear end of lock machine (4) rotor, and clamp (5) is actually an eccentric cam; Latch (6) and the hairclipper (8) of cover upper reset spring is equipped with in the below, and the rear end of latch (6) is boss (7). All have latch jack (10) on five cun tubes (1) and the car fork tube (9). Be welded with stiffening ring (11) on the inwall that mortise lock jack (10) on the car fork tube (9) is located, to strengthen the rigidity of car fork tube (9). With reference to Fig. 2, during the lock car, at first rotate handlebar, make the latch jack of latch jack on five cun tubes (1) on the car fork tube (9), press hairclipper (8), latch (6) is advanced in the latch jack (10), rotate key the rotor on the lock machine (4) is rotated, the clamp of rotor rear end (5) namely down then the boss (7) that blocks latch (6) rear end can not retreat it is decontroled hairclipper (8) it is resetted under spring action, extract key out, bicycle namely is lockable.

The utility model anti-theft bicycle is simple in structure, and is easy to manufacture, open, lock side just, dependable performance. Bicycle is once pinning, front-wheel and dead ahead 30 Degree ┄ 60 degree angles, bicycle namely can not push away away forward or ride away. Lock is contained in the lock housing, is difficult for by from external damage.

Be an embodiment of the present utility model below: metal lock housing (3) collapses and is welded on five cun tubes (1) and the cant beam (2).The structure of lock machine (4) and common spring are phase-locked together, but the rear end of copper rotor (place, key hole) adds the defeated shape clamp (5) of metal metaphosphate cardiac prominence of weldering.Metal skewer pin (6) is made the T type, and front end is the inclined-plane and makes vertical cambered surface so that make in the car fork tube (9) behind the reeve latch jack enough space mounting handlebars are arranged.Hairclipper (8) available metal or plastics are made cross, can seesaw within the specific limits under the cooperation of retracing spring.For the ease of installing and fixing, lock machine (4), latch (6) and hairclipper (8) can be contained in respectively in separately the chest, and the anchor block (13) on the latch case is tightened and pin cabinet and hairclipper case, the latch case then withstands on five cun tubes (1) and goes up and be fixed in the lock housing (3) by fix screw (12).During installation, on the desired location in the lock housing (3) of earlier hairclipper case and lock machine case being packed into, reinstall the latch case, the anchor block on the latch case (13) is clamping lock cabinet and hairclipper case, puts on fix screw (12) again and it is tightened to get final product.For the purpose of installing, the latch jack on five cun tubes (1) should be greater than the latch jack on the car fork tube (9).
