Description

Pusher-bar double-bolt theft-proof lock

The utility model relates to a kind of bicycle theft-prevention protective device.

Existing bicycle lock generally has three kinds of form of structure: a kind of is the annular enclosed type structure, and second kind is cross-latch type (not sealing) structure, and the third is a chain structure.The annular enclosed type bicycle lock generally is installed on the mud breeches pipe under the bike saddle saddle, is mainly used in the trailing wheel of lock bicycle, and the cross-latch type bicycle lock is installed on the front fork tube of bicycle, is mainly used in the front-wheel of lock bicycle.The common drawback of these two kinds of bicycle locks is, only is applicable to the self-locking of single bicycle, and can not realizes the interlocking of many bicycles, and the perhaps interlocking of bicycle and certain fixture (railing, electric pole etc.), thereby theftproof performance is relatively poor.Though the chain type bicycle lock can solve the interlocking problem of many bicycles, the chain of locking owing to bolt is very easily destroyed by pliers one class hardware ﹠ tools, so antitheft reliability is relatively poor.In addition, these three kinds of bicycle locks also exist locking bar and lock body is inseparable, dead bolt is single, when unblanking, car key need rotate to an angle, after unblanking, key such as can not take out at shortcoming, like this, not only brought inconvenience, and influenced the reliability of lock and the application life of lock to the user.

The utility model is intended to overcome the problem of above-mentioned existence, and a kind of single bicycle self-locking that both can be used for is provided, and also can be used for many bicycles interlockings, push-down double lock tongue theftproof lock sturdy and durable, easy to use.

For realizing the task of above-mentioned proposition, the utility model has been taked following measure: the lock body of push-down double lock tongue theftproof lock and locking bar adopt separate type; Locking bar adopts U type structure, and the two ends of U type structure are provided with locked groove; Be provided with the double lock tongue structure in the lock body, the push-down control mode is adopted in the unlatching of dead bolt, and promptly as long as key is inserted in the lock core, inside one pushes away, and can open lock.

Provided structural representation of the present utility model in the accompanying drawing, wherein:

Fig. 1 is the utility model appearance structure schematic diagram

Fig. 2 is the structural representation of the utility model lock body socket

A-front view b-vertical view c-sectional view

Fig. 3 is the utility model cut-away view

Fig. 4, Fig. 5 are other two kinds of structural representations of the utility model lock body

Below in conjunction with accompanying drawing the utility model is elaborated: push-down double lock tongue theftproof lock is made up of theftproof lock 1 and lock body socket 2 two large divisions.Lock body socket 2 contains a receptacle ferrule 3 and a receptacle ferrule positioning sleeve 4, and receptacle ferrule 3 and receptacle ferrule positioning sleeve 4 adopts bolts 5 to be connected, and is fixed in by positioning bolt 6 on the standpipe of hundle-bar, so that the hanging of the theftproof lock after the unlatching.

Theftproof lock is made up of lock body 7 and locking bar 8 two parts.Lock body 7 and lock body bar 8 are designed to separate type.Lock body 7 is a bar shape structure, on lock body 7, is provided with two locking bar jacks 13, and locking bar is inserted in 13 and is provided with dead bolt 11 and spring 12.Dead bolt 11 in the locking bar inserted link can be that to be provided with in the same way also can be incorgruous setting.One end of lock body 7 is provided with lock core 15, and the other end is equipped with end cap 17.In lock body, be provided with one and be used to control the push rod 10 that dead bolt 11 is opened, an end of push rod 10 is connected with lock core 15 by bolt 14.For ease of the making and the installation of push rod, push rod 10 adopts with dead bolt 11 and directly promotes control mode, and promptly push rod and dead bolt are to adopt the pushing tow mode to control the unlatching of dead bolt.In addition, push rod 10 can also adopt push rod to add the promotion control mode (seeing Fig. 4, shown in Figure 5) of connecting rod with dead bolt 11, be to adopt connecting rod 18 to connect between push rod 10 and two dead bolts 11 to be one, directly control the unlatching of dead bolt 11 by push rod, connecting rod, or dead bolt is connected with pushing away mutually by connecting rod 18, and on the connecting rod 18 of another dead bolt, is equipped with a fulcrum 19, push rod 10 makes connecting rod 18 rotate around fulcrum 19 and reaches the purpose that two dead bolts are opened simultaneously by promoting connecting rod 18.

The locking bar 8 of theftproof lock is designed to a steel tubular structure that is the U type, and its two ends are respectively arranged with dead bolt draw-in groove 9.At the self-locking of bicycle different parts, the interlocking of many bicycles, reach the interlocking of bicycle and certain fixture for ease of theftproof lock, the length of U-shape lock bar 8 can be mated arbitrarily.

Working method of the present utility model is achieved like this: earlier lock body socket 2 is fixed on the standpipe of hundle-bar by positioning bolt 6.By bike the time, the lock body 7 of theftproof lock can be inserted in the sleeve pipe 3 of lock body socket, so both attractive in appearance, reliable and stable again.During parking, lock body 7 is taken out in receptacle ferrule, because lock body 7 can be separated from each other with receptacle ferrule 3 and U-shape lock bar 8, the U-shape lock bar can mate arbitrarily in addition, so not only can realize self-locking, and can realize the interlocking of many bicycles and the interlocking of bicycle and fixture at any position of bicycle.When locking, U-shape lock bar 8 is inserted in the locking bar jack 13 of lock body, the spring 12 in the locking bar jack promotes dead bolt 11 and snaps in the dead bolt draw-in groove 9 of U-shape lock bar, thereby finishes the action of lock car.When unblanking, car key 16 is inserted in the lock core 15, and lock core 15 pushed inward, at this moment, lock core inwardly moves and promotes push rod 10, and push rod 10 promotes the elastic force that dead bolts 11 overcome spring 12, makes dead bolt 11 jump out dead bolt draw-in groove 9 on the U-shape lock bar, U-shape lock bar 8 can take out from lock body 7, thereby realizes the unlatching of lock.Lock body after the unlatching can be reentered in the lock body socket sleeve pipe, so that carry and prevent loss.

The utility model novel structure, installation, easy to use, because the lock body and the U-shape lock bar of theftproof lock have adopted separate type, and the length of U-shape lock bar can be mated arbitrarily, so not only solved self-locking problem at any part of bicycle, and realized the interlocking of many bicycles and the interlocking of bicycle and fixture, thereby improved the theftproof performance of bicycle on the whole widely.
