CN2262594Y - Double bolt bicycle lock - Google Patents

Abstract

The utility model relates to a bicycle lock with double inserting bolts, which is composed of a lock body, a lock core, inserting bolts, a pressing plate, etc., wherein, the inserting bolts are composed of two inserting bolts; one inserting bolt is an active inserting bolt which is controlled by the lock core; the other inserting bolt is a passive inserting bolt which is connected with the active inserting bolt; the two inserting bolts are connected by the handle of the inserting bolt to form a U-shaped structure. The lock is arranged on the front fork leg of a bicycle; owing to the two inserting bolts, the spokes of a wheel can be blocked when the lock is rotated or is knocked to the bottom, and thus the utility model has high theftproof performance. The hole of passive inserting bolt is a swinging hole for the swinging of the inserting bolts; after the lock is opened, the active inserting bolt can rotate slightly; bayonets on the inserting bolts are blocked by pins, obtaining the purpose of self-locking prevention.

Description

Two plug bicycle locks

The utility model relates to bicycle lock, is specially adapted to be installed on the bicycle front fork leg.

The kind of bicycle lock is a lot, but presses the shape difference of its plug, can be divided into crab claw lock and straight-bar lock, and crab claw lock generally is installed in the back vehicle frame, the pinning trailing wheel; And the straight-bar lock generally is installed on the fork blade, pins front-wheel.Be installed in the straight-bar type bicycle lock on the fork blade, be single plug, if the angle of lock is rotated, perhaps with the upper coarse and lower fine characteristics of fork blade, will lock down and strike, lock is changeed a direction, plug just can not block the steel ring spoke like this, and car just can freely be carried out.Therefore, the disadvantage of existing such lock is that theftproof performance is poor.

The purpose of this utility model is a kind of being installed on the bicycle front fork leg of design, and lock is rotated, and perhaps will lock and down strike the bottom, is parked on the unspecified angle, can both block the lock of width of cloth bar.

The technical design scheme of the two plug bicycle locks of the utility model is: be made up of institutes such as lock body, lock core, plug and pressing plates, its so-called plug is two, an active plug of controlling for lock core, and another root is for connecting the initiatively passive plug of plug.

Of the present utility model pair of plug bicycle lock, its active plug is linked to each other by the plug handle with passive plug, and whole plug is the U font structure.

Of the present utility model pair of plug bicycle lock, the keyhole of passive plug are greater than the diameter of plug, and preferably long trough is one and can supplies the pendulum hole of plug swing.

The utility model discloses a kind of pair of plug bicycle lock, compared with the prior art, it is good to have a theftproof performance, after lock is rotated, is perhaps down struck the bottom, is parked on any angle, and spoke is always blocked by plug.And after unblanking, passive plug can be swung, and makes initiatively a little rotation of plug, and the bayonet fittings by on pin in the lock body and the active plug produces anti-auto-lock function.

Fig. 1 is the two plug bicycle lock schematic perspective views of the utility model;

Fig. 2 is the two plug bicycle lock vertical views of the utility model;

Fig. 3 is that the two plugs of the utility model are the U font, and initiatively on the plug chute and bayonet arrangement schematic diagram is arranged.

Below in conjunction with Fig. 1～Fig. 3 embodiment of the present utility model is done detailed explanation.

1. lock body; 2. lock core; 3. key; 4. plug initiatively; 5. pressing plate; 6. passive plug; 7. pendulum hole; 8. plug handle; 9. screw; 10. chute; 11. anti-self-locking bayonet.

The utility model relates to bicycle lock, particularly relates to the bicycle lock that is installed on the fork blade.A lock body 1 is arranged, lock core 2 is installed in the lock body, the key 3 of unblanking fixes the pressing plate 5 of usefulness by screw 9 and lock body, lives steel wire (or claiming spoke) with the structure shelves of two plugs, be divided into initiatively plug 4 and passive plug 6, two plugs link to each other together, preferably adopt U font structure, and plug handle 8 is arranged, two plugs are locked simultaneously, withdraw from simultaneously.Two plugs have been arranged, be rotated at lock, perhaps struck the bottom of front fork, the front-wheel spoke is still lived by the plug shelves.It is big that want in the aperture of passive plug 6, preferably long trough, or title pendulum hole 7, after unblanking, passive plug produces swing, and causes initiatively a little rotation of plug, owing in the lock body pin is arranged, pin matches with the chute 10 of active plug, after rotation, pin enters anti-self-locking bayonet 11, reach the rear defence self-locking purpose of unblanking, because be to enter automatically, can human error, this effect is very reliable, avoids producing " self-locking " and causing accident in when driving.When locking, with passive plug holder once, make pin disengagement bayonet socket 11 and enter chute 10, more whole plug is pushed away inward.

Claims (3)

1. two plug bicycle locks are made up of institutes such as lock body, lock core, plug and pressing plates, it is characterized in that plug is two, an active plug of controlling for lock core, and another root is for connecting the initiatively passive plug of plug.

2. as claimed in claim 1 pair of plug bicycle lock is characterized in that initiatively plug (4) is linked to each other by plug handle (8) with passive plug (6), and whole plug is the U font structure.

3. as claimed in claim 1 pair of plug bicycle lock, the keyhole that it is characterized in that passive plug are pendulum holes (7) greater than the plug diameter.
