CN2918669Y - Synchronous automatic locking for bicycle three-preventing support - Google Patents

Abstract

The utility model relates to a synchronous automatic lockout mechanism for the support with three-prevention effect of the bicycle which replaces the traditional manual-locking mode for the lock of the bicycle by knocking the bicycle with the foot. The utility model retrofits a lock line between the new lock for the bicycle and the support, which makes both ends of the lock line cable separately connected with the set bar of the lock and the support bar of the bicycle. Both ends of the wrap of the lock line are separately connected with the lock body and a mounting plate of the support, which makes the set bar and the support realize synchronizing drive. The end of the set bar of the lock is of spherical head, on top of which a locking hole is arranged. A lock pin is arranged in the lock head. Driven by the lock pin spring, the head of the lock pin extends and remains in the locking chamber to be locked. When the movement of the support rod drives the set bar to rotate via the lock line cable and makes the spherical head inserted into the locking chamber, the lock pin automatically inserts into the locking hole and is locked. Thus, the general performances of the lock pin such as the convenience, the practicability, the reliability and so on reach an unprecedented level.

Description

Bicycle three anti-cars support synchronous automatic locking

The utility model relates to the locking of light traffic, fitness tool bicycle lock and the redesign of maneuverability pattern.This design is the scheme that adopts lock lock bolt and the interlock of car support strut, has simplified operation when improving the locking reliability, and its function and effect are fully reflected, and reaches safe and reliable target.

At present, the lock mode of bicycle lock still rests in the manual operation, and existing defective of manual manipulation mode and operational inconvenience fail to be overcome always.As forget after forgetting the lock car after parking or locking car and win key; Although the various lock on the market is various in style so far for another example, external form is different, and its lock mode is of an identical nature substantially.The various theftproof lock that has come into the market also is only limited to the reinforcement on the lock body part component intensity, and its locking position still is weak.Because bicycle lock not have bigger breakthrough so far on its locking and mode of operation, cause reliability and convenience long stagnant not before, thereby influenced the social benefit and the economic benefit of product.

The purpose of this utility model is to be bicycle designs function admirable, good reliability, the locking device of simple operation.Event when this design utilizes people to stop has action, adopts lock lock bolt and car support strut to realize interlock, and genlocing in bike stand's car need not the manual lock car.Because of key employing " general gets down from horse " formula of this design lock, key can be carried.Therefore, can prevent to forget that lock car or lock are forgotten behind the car wins key.After the locking of this design lock taked the lock bolt spherical head to embed the tapered end latch well, lock pin inserted the mode that locks in the lock hole on lock bolt ballhead top automatically, makes its pick-proof performance reach perfect condition.

The purpose of this utility model realizes by following mode: install a locking wire additional between lock and car support, its locking wire adopts the bicycle brake line.Locking wire cable wire two ends is connected firmly with lock lock bolt and car support strut respectively; Locking wire overcoat two ends connects firmly with lock lock body and car support installing plate respectively, thereby makes lock lock bolt and car support strut realize synchronous interaction.Lock lock bolt termination is band neck ballhead, and a lock hole is established on the ballhead top; The lock pin of device one head band tapering in the tapered end, lock pin its head under the promotion of lock pin spring stretches into and resides in the tapered end latch well, is in the lock state for the treatment of.The locking wire cable wire that moves through at car support strut drives the lock bolt rotation, and when making its ballhead embed tapered end latch well, latch well is the stuck location on each orientation except that import and export with its neck and head, and simultaneously, lock pin promptly inserts lock hole automatically and locks.

Owing to adopt above-mentioned design scheme, broken the situation that conventional manual lock car for a long time unifies.Make its operation more convenient, combination property is more safe and reliable, and its lock is except that with key operated or carry out being difficult to remove its lock-out state the destructive decomposition, thereby reaches pick-proof, anti-ly forget lock, forgets to win three anti-purposes of key behind the anti-lock.This scheme is tested after reequiping, and has confirmed the feasibility and the advance of design scheme.

In the accompanying drawing: 1, give up the throne push rod 9, tapered end 10, lock pin 11, lock core 12, lock pin spring 13, car strut 14, car support installing plate 15, locking wire cable wire guide plate of shank 2, lock bolt position limitation protection cover 3, lock bolt back-moving spring mechanism 4, lock bolt 5, locking wire overcoat 6, locking wire cable wire 7, tapered end assembling case 8, lock bolt

In the accompanying drawings: the spacing guarantee cover of lock bolt (2) connects firmly with lock body (1); Lock bolt (4) connects firmly with lock bolt back-moving spring mechanism (3); The axle and the lock body (1) of lock bolt back-moving spring mechanism (3) connect firmly; The two ends of locking wire cable wire (6) connects firmly with lock bolt (4) and car strut (13) respectively; The two ends of locking wire overcoat (5) connects firmly with lock lock body (1) and car support installing plate (14) respectively; Tapered end assembling case (7) and tapered end (9) connect firmly with lock body (1); Lock bolt is given up the throne in the hole that push rod (8) is installed in the tapered end (9) with latch well communicates, and lock pin (10) and lock bolt push rod (8) state of being orthogonal of giving up the throne is installed in the tapered end (9), and lock pin spring (12) is installed in the tapered end (9) and occupies the lock pin tail end; Locking wire cable wire guide plate (15) connects firmly with car strut (13); Car strut (13) and car support installing plate (14) pin connection.When need bike stand puts, the locking wire cable wire that moves through of car strut (13) drives the axle do synchronously rotation of lock bolt (4) in lock bolt back-moving spring mechanism (3), when car strut (13) moves to the upright point of support position, the spherical type head of lock bolt (4) is embedded into latch well, and lock pin this moment (10) inserts under the thrust of lock pin spring (12) in the lock hole on lock bolt ballhead top and reaches lock-out state.When bicycle lock need be opened, earlier retract lock pin (10) with key rotation lock core (11), the lock bolt ballhead withdraws from latch well under lock bolt is given up the throne the effect of push rod (8) and lock bolt back-moving spring mechanism (3), state unlocks, can play the motor-car strut this moment backward, support under the acting in conjunction of spring with car in lock bolt back-moving spring mechanism (3), lock bolt and car strut reset simultaneously.
