Description

Bicycle, the motor bike anti-theft column lock that automatically locks

The utility model belongs to a kind of bicycle, the motor bike anti-theft column lock that automatically locks.

At present, the car anti-theft column lock has varied, as patent 94227569.1 anti-theft lock for motorcycle, and patent 95211133.0 bicycles, motor bike lockset, structure is complicated, and anti-theft capability is strong inadequately, and it is convenient inadequately to use, and can not automatically lock.

The purpose of this utility model is to provide a kind of fixed-site that is installed in, and can make the lockset that bicycle, motor bike automatically lock, anti-theft capability is strong, easy to use.

The utility model is made up of push rod (1), gear (2), retracing spring (3), lock ring (4), tapered end (5), dead bolt (6), main shaft (8), retainer spring (10), support (12), lock box (13).Support (12) is fixed on fixed-site, and lock box (13) is contained on the support (12) by main shaft (8), and push rod (1) is housed on the lock box (13), and retracing spring (3) is arranged on the push rod (1), and push rod has tooth bar on (1); Gear (2) and gear wheel shaft are housed in the lock box (13); Lock ring (4) is housed in the lock box (13), and lock ring has tooth bar on (4); Gear (2) and the engagement of push rod (1) tooth bar, gear (2) and the engagement of lock ring (4) tooth bar; One end of lock box (13) is equipped with tapered end (5); (4) one of lock rings are pulled to tapered end (5) when locating, the recess interlock on dead bolt (6) on the tapered end (5) and the lock ring (4).

The utility model is simple in structure, and support (12) is equipped with about 20-50 centimetre place on the foundation by swell fixture (7), and bicycle or bike wheel are aimed at lock ring (4) and advanced and can lock, and save the loaded down with trivial details action that the people bends over to bend knee and locks, and use easily.In addition, the utility model anti-theft capability is strong, and cost is low.Manufacture easily.

Description of drawings:

Fig. 1 is the utility model structural representation.

As shown in Figure 1, lock box (13) has the swing space of 30 degree in support (12), between main shaft (8) and support (12) retainer spring (10) is housed, and is torsion spring, and lock box (13) is done the swing back slightly and resetted by retainer spring (10).Push rod (1) head has push rod top (9), accepts the thrust of wheel.Lock ring can be equipped with retracing spring on (4), and retracing spring (3) can be replaced by the retracing spring that is contained on the lock ring (4), also can on lock ring (4) and push rod (1) retracing spring be installed all, to increase reset capability.Gear (2) is made up of concentric gear, and the radius ratio of concentric gear is about 1: 2.Gear (2) also can be meshed by two out-of-alignment gears and form, and tapered end this moment (5) is contained in the opposite end of lock box (13).

As shown in Figure 1, when locking, wheel thrust makes push rod (1) motion in push rod top (9), drives concentric gear (2) and rotates, and power is passed to lock ring (4), and lock ring (4) directly reaches dead bolt (6) till the recess (11) of lock ring is locked.When unblanking, open tapered end (5) with key, dead bolt (6) withdrawal because retracing spring (3) thrust in push rod (1), makes concentric gear (2) rotate, drives in lock ring (4) the withdrawal lock box (13), finishes the program of unblanking.

If wheel thrust is when push rod top (9), lock ring (4) just in time bumps the spoke in wheel, and at this moment the spring of main shaft (8) can twist the scope of 60 degree, makes lock ring (4) avoid vehicle wheel spoke and locks.
