Abstract
The utility model relates to a semi-automatic lock for bicycles. A lock body is composed of a lock core, a lock bolt and a lock rod. The utility model is characterized in that a discoid lock casing is used and the discoid lock and a rear wheel of the bicycle are coaxially arranged. The lock rod is a cambered rod which propels along the periphery of the lock casing and rotates along a heel brace of the bicycle. A gear ring is arranged and fixedly connected to a rear wheel shaft of the bicycle and forms corresponding rotation with the lock casing. An on-off cambered gear rack is engaged with the gear ring. One end of the gear rack is hinged on the side wall of the lock casing, and the other end is connected with the tail part of the lock rod by a tension spring. The parking and the locking of the utility model are completed once, so that the utility model has the advantage of convenient and reliable use.
Description
The utility model relates to lockset, more particularly, is a kind of bicycle lock.
At present the bicycle lock that generally uses all is that for bicycle heel brace Zhi Wenhou is gone with lock on hand again, and all is to interlock with the dead bolt that locking bar passes wheel and core part, the wheel of bicycle can not be rotated, to reach the purpose of pinning bicycle.Tired rope and parking and two ones of the branches of locking are walked owing to lock, and have often stopped car and have just forgotten lock, so that lose car, cause unnecessary loss, make troubles to use simultaneously
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of semiautomatic bicycle lock is provided, and parking and lock car are once finished, the convenient use.
The purpose of this utility model is achieved through the following technical solutions.
The utility model cooperates the locking bar of locking to constitute lock body by lock core, dead bolt with dead bolt.
Design feature of the present utility model is:
The discoid lock housing of a, employing and the coaxial setting of bicycle rear, described locking bar is a bow that can advance along the lock housing circumference with the rotation of bicycle support leg;
B, be provided with and connect firmly on bicycle rear shaft, can form gear ring in relative rotation with lock housing, but with this tooth on the gear teeth mutually interlock be the arc-shaped rack of clutch, arc-shaped rack one end is hinged on the lock housing sidewall, the other end is connected the locking bar afterbody by extension spring.
The utility model is after parking, also having finished bicycle when propping up the stable car body with bicycle support leg locks, accomplish to stop to lock and accomplish without any letup, so both can avoid bicycle of the prior art only after putting stable car, remove the tired Suo Fangfa that locks again, also can avoid sometimes forgetting to lock behind the stable car and causing losing of bicycle because of putting.The utility model lock car is reliable, easy to use, simple and practical.
Accompanying drawing is the utility model structural representation.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to accompanying drawing, present embodiment is to cooperate the locking bar 3 of locking to constitute lock body by lock core 1, dead bolt 2 with dead bolt 2.
In the present embodiment, adopt the discoid lock housing 4 with the coaxial setting of bicycle rear, locking bar 3 is one can be with the rotation of bicycle support leg along the bow of lock housing 4 circumference propelling.
Setting connects firmly on bicycle rear shaft, can form gear ring 5 in relative rotation with lock housing 4, but with the gear teeth on this gear ring 5 mutually interlock be the arc-shaped rack 6 of clutch, arc-shaped rack 6 one ends are hinged on lock housing 4 sidewalls, the other end is connected the afterbody of locking bar 3 by extension spring 7, and what be oppositely arranged with extension spring 7 is tooth bar return spring 8.
Whole lockset divides the two major parts assembling, and one is that lock core 1, dead bolt 2, locking bar 3, arc-shaped rack 6 and extension spring 7 and tooth bar return spring 8 are installed in the lock housing 4; Another piece is the installation of relevant gear ring 5, gear ring 5 can be movable gear ring, its mounting method is earlier gear ring 5 to be enclosed within on the bicycle left rear axle bowl, the gear ring stator is set, the gear ring stator is stuck on the central siphon of left rear axle floral disc inboard, pass the spoke slit and the gear ring fixing hole of gear ring stator and Y-axis floral disc top with bolt, gear ring is fixed on the left rear axle bowl, gear ring is with wheel.The gear ring of this frame mode is detachable, on the bicycle that is installed in different model.In addition, gear ring also can be directly to be fixedly installed between bicycle left rear axle bowl and the left back floral disc, with wheel with press.After the gear ring fixed installation, the lock housing integral part that assembles is passed through trailing wheel left side bottom bracket axle outside gear ring, fixing cycle frame back vent and body support in its outside.Available book iron sheet or book aluminium flake by bolt on the crossbeam that is fixedly mounted on the vehicle frame back vent of lock housing, to reinforce the stable of lock housing integral part.
In concrete the enforcement, locking bar 3 connects firmly on bicycle support leg.Rotate heel brace and prop up when stopping bicycle, locking bar 3 is pushed into, and until interlocking with dead bolt 2, at this moment, arc-shaped rack 6 is owing to the tractive of locking bar 3, and with the gear teeth interlock on the gear ring 5, bicycle rear is locked.Unblank process in contrast, at first, promote heel brace, with key rotation lock core 1, the lock tongue slot that dead bolt 2 is broken away from the locking bar 3, because the effect of tooth bar return spring 8, arc-shaped rack 6 resets, and separates with gear ring 5, at this moment, gear ring 5 can freely rotate, and is unlocking condition.
Arc-shaped rack 6 in the present embodiment and the occlusion structure between the gear ring 5 also can be substituted by friction plate.
