Abstract

The utility model relates to an anti-theft safety lock in a double-lock type for a bicycle, which comprises a lock frame, a lock core with a spring lock head, and a lock rod, wherein the lock core with a spring lock head and the lock rod are arranged in a lock body of the lock frame. The utility model is characterized in that a digital cipher lock which is matched with a common spring lock is simultaneously arranged in the lock body of the lock frame in an integrative mode. The spring lock can be unlocked only after the cipher lock is unlocked, a lock head of the lock frame is arranged on a front oblique pipe of a bicycle frame, and the lock rod matched with the lock head of the lock frame is a U-shaped lock rod which can be inserted. Compared with the prior art, because the cipher lock and the spring lock are simultaneously arranged on the lock frame in an integrative mode, the utility model has advantages of good anti-theft and anti-prying effects, simple structure and convenient installation, and is suitable for the bicycles with various models.

Description

Twin-lock head dummy bicycle theft-prevention safety lock

The utility model belongs to a kind of anti-theft lock for bicycle designing technique, especially a kind of twin-lock head dummy bicycle theft-prevention safety lock with integral structure.

Though existing anti-theft lock for bicycle is various in style, form of structure variation, pick-proof poor performance.Though the bicycle tamper-resistant safety lock of selling the pick-proof better performances is arranged in the market, because the overall shape of these pick-proof locks and the position (generally being installed on the trailing wheel limit) of installation are the same with traditional bicycle lock, though thief's sled does not for the moment unblank, but the thief with hang on the waistband dark hook hook block car after-frame by trailing wheel liftoff a little the time, can as usual with hand car be pushed away away, car owner or other people all are difficult to find.Sometimes with behind the rear wheel lock again at front-wheel with soft lock as lock, front-wheel is locked, but the thief can push away away car equally easily as long as cut the soft lock of front-wheel with " break joint pliers ".

The purpose of this utility model provides a kind of twin-lock head dummy bicycle theft-prevention safety lock, makes to have easy to installly, and the anti-theft pick-proof good effectiveness can allow the burglar can only hope car heave a sigh.

The utility model is realized with following technical scheme: it comprises the lock frame, be installed in ball lock head, lock core (for the common spring lock core) in lock frame one end lock (shell) body, and locking bar constitutes, it is characterized in that in lock frame lock body (lock housing body) that also integral type is provided with a digital cipher lock that is used with this common spring lock simultaneously, and make and open ability unlocking spring lock behind the coded lock; To lock the frame tapered end in addition and be installed on the forward inclined tube of taking turns of vehicle frame, the locking bar (bolt) that face cooperates with lock frame tapered end is that system is the pluggable locking bar of " U " shape, and after locking, this locking bar can be with the front-wheel locking.

Compared with the prior art, the utility model is owing to install coded lock and two kinds of tapered ends of cylinder lock simultaneously on a lock frame, coded lock and cylinder lock all can adopt the lock structure of common prior art (generally can be designed to the structural principle of similar safety cabinet cipher door lock, must open unlocking spring lock behind the coded lock earlier), have following technological merit:

1, can prevent effectively that the thief from unblanking with MASTERKRY.

2, lockset is installed on the preceding inclined tube position of vehicle body, when adopting the pluggable locking bar of " U " shape sealed with front wheel steel ring and tire locking together, handlebar can not swing, front-wheel can not about turn to, the dark hook that the thief be difficult for to be utilized hang on the waistband is dragged car away.

3, with the lock critical piece as " U " shape locking bar, lock bodies etc. adopt the alloy steel manufacturing, through Overheating Treatment, and the intensity height, no matter the thief can not open with instruments such as pliers, hammer, wrench, screw rotating tool, hacksaw, cutter, file even large-scale disconnected joint pliers, the pick-proof and anti-theft performance is good.

If 4, the dress lock is convenient, the dress time is short (only needing about one minute time), almost any vehicle all can be loaded onto this lock.

Below in conjunction with accompanying drawing embodiment concrete structure of the present utility model is described in further detail.

Fig. 1 is a kind of assembly structure schematic diagram of the present utility model.

Fig. 2 is that the utility model safety lock is installed in the schematic diagram on the preceding inclined tube of vehicle frame.

Wherein: 1～lock (shell) body, 2～lock frame, inclined tube before 3～vehicle frame, 4～ball lock head, 5～lock cylinder, the lockhole at 5.1～lock cylinder place (inserting key uses), 6～mechanical code lock, 6.1～inserting bolt type locking bar, 7～numerical ciphers knob, 8～hold-down screw, 9～installation sheet, 10～" U " the pluggable locking bars of shape, 11～front-wheel fender, 12～front tyre, 13～front wheel steel ring, 14～steel wire, 15～handlebar.

With reference to accompanying drawing as can be known, its used digital cipher lock can be to adopt standard machinery coded lock (for example: can be the coded lock of knob or the coded lock of push button) when the utility model was made in specific design, the tapered end lock core of this coded lock can be installed in the same end of lock frame with cylinder of spring lock, also can public not be installed in the two ends of lock frame.

The coded lock of opening earlier of the present utility model, after could unlocking spring lock, promptly the mode with coded lock control or restriction cylinder lock has multiple (control structure of the cipher door lock of reference safe door of the prior art flexibly).And in the utility model, when the tapered end lock core with coded lock is installed in the same end of lock frame with cylinder of spring lock, can adopt the inserting bolt type locking bar of using coded lock 6.1 shown in the accompanying drawing 1 to hide the structure of lockholes 5.1, the locking bar that is about to coded lock is made the structure of inserting bolt type, before unlocking coded lock, allow an end of its inserting bolt type locking bar cover in pellet shot from a slingshot lockhole 5.1, make key can't insert the lockhole unlocking spring lock, after coded lock is unlocked, allow its inserting bolt type locking bar backward (to the right) move the pellet shot from a slingshot lockhole exposed, can insert key operated cylinder lock; When the tapered end lock core of coded lock and cylinder of spring lock were installed in lock frame two ends respectively, structure such as can adopt password locking bar push-type or inlaid type (can with reference to the restriction syndeton of safety cabinet door lock, figure slightly) was unlocked earlier with the restriction cylinder lock.
