Description

A chain of antitheft lock set

The utility model belongs to the bicycle lock technical field, is the antitheft lock set of a kind of chain of rings.

Bicycle is one of people's main tool of riding instead of walk.At present, the stolen phenomenon of bicycle is very serious, and this has not only caused the certain economic loss to the car owner, has brought many inconvenience and worried also for car owner's work, studying and living.For antitheft, the way of taking usually is: 1. lock simultaneously on the front and back wheel of bicycle.Though this method can play antitheft effect to a certain extent because outside the lock that adds usefulness often all is exposed to, still easily by the burglar with the reinforcing bar pincers or change tools used in crime such as cutter or master key and cut off, pry open or breakdown, lose antitheft effect.2. together with Ring lock with steel wire or chain lock and other bicycle Series lock.Though this method is than preceding a kind of method, got rid of easily the move stolen phenomenon of single bicycle because of the robber, but still easily clamped on the one hand or tool used in crime such as master key destroys by reinforcing bar, ineffective, and on the other hand to extremely inconvenient by taking of Series lock last bicycle car owner together, all the more so when not knowing each other especially mutually.

The purpose of this utility model is intended to solve the problem that prior art exists, and modes such as intending providing a kind of burglar of preventing to adopt and cut, prize, open is destroyed, and can conveniently take a chain of antitheft lock set of bicycle again.

The purpose of this utility model is reached by a kind of like this technical scheme: should the antitheft lock set of the chain of rings be to be made of main lock and secondary lock promptly, and main lock and secondary lock are made up of fixed cover, connecting rod, lock tube and cylinder lock respectively.Fixed cover is " U " shape, and its two ends are connected in connecting rod one end termination by the rivet activity.The connecting rod other end termination lock tube that is connected, lock tube is a groove shaped, notch is outside, notch two ends correspondence respectively have through hole and blind hole, and internal thread is arranged on the blind hole, and through hole and blind hole be shaped as Long Circle.The cylinder lock profile is "T"-shaped, and the lock core leading section has external screw thread, is fixedly connected on lock tube can pass lock tube through hole and blind hole internal thread.Pellet shot from a slingshot in the cylinder lock has at least one to be stairstepping.

During use, main lock and secondary the lock fixed cover by separately respectively are installed on the fork thick stick under the bike saddle with rivet.Because the cylinder lock on its major and minor lock lock tube all can be opened and unscrews and withdraw from blind hole to through hole one side by key, thereby the cylinder lock of working as major and minor lock retreats to through hole one rear flank, the notch of its lock tube is open, just can make the main lock of two bicycles of left and right sides or the inboard that the cylinder lock in the secondary lock lock tube enters notch, at this moment again cylinder lock is passed notch and enter blind hole and tighten and lock, just can interlock in the bicycle of the left and right sides.And also very convenient when taking, only need with key with the main lock of bicycle or/and the secondary cylinder lock of locking open and unscrew withdraw from blind hole to through hole one side just can with other bicycle lock disengagement.Owing to the stress point that does not have after the utility model installation Gong to prize; and after major and minor lock butt joint is chain; lock tube is about in cylinder lock all is coated on; carried out seal protection; add the step-like pellet shot from a slingshot of at least one grain has been installed again in cylinder lock, the theft conduct that causes so prevented robber's the destruction of methods such as cutting, prize, open fully.

Fig. 2 is the main TV structure schematic diagram of secondary lock;

Fig. 3 is the contour structures schematic diagram of cylinder lock;

Fig. 4 is the structural representation of the stairstepping pellet shot from a slingshot in the cylinder lock;

Fig. 5 is the cross-sectional view of major-minor lock butt joint back lock tube.

Also the utility model is described in further detail to provide embodiment below in conjunction with accompanying drawing.

As shown in Figure 1, 2, a chain of antitheft lock set that present embodiment provides is to be made of main lock 1 and secondary lock 2, and main lock 1 and secondary lock 2 are made up of fixed cover 3, connecting rod 5, lock tube 6 and cylinder lock 10 respectively.

Fixed cover 3 is " U " shape, and its two ends correspondence has through hole, and when being installed on the bicycle fork thick stick, is connected in connecting rod 5 one end terminations with a rivet 4 bolt knot activities, and making connecting rod 5 can serve as the rotations that axle is made 180 degree with rivet 4, with convenient chain and fixing.Connecting rod 5 other end terminations lock tube 6 that is connected.Lock tube 6 is a groove shaped, and notch is outside, and notch both ends correspondence respectively have through hole 8 and blind hole 9, on the blind hole 9 internal thread are arranged.Through hole 8 and blind hole 9 be shaped as Long Circle, do not allow it rotate with shell cross sectional shape coupling with core 11 with cylinder lock 10.Cylinder lock 10 profiles are "T"-shaped, and lock core 11 leading sections have external screw thread, see Fig. 3, are connected and fixed with blind hole 9 screw-internal thread fit can pass lock tube through hole 8.Pellet shot from a slingshot 12 in cylinder of spring lock 11 has at least one to be step-like, as shown in Figure 4, robber's master key just can not be squeezed into it outer pellet shot from a slingshot hole to make lock core be hollow playing a role like this, and then core 11 is rotated withdraw from blind hole 9 screw threads and untie chain together with whole cylinder lock 10 retreats to lock tube through hole 8 one sides.In order to protect "T"-shaped lock not cut off by the robber, it is partly fan-shaped that cell wall 7 cross sections of lock tube are, and its fan arc length is the  of circumference; so that major and minor lock 1,2 chain after; one of the cross section formation of base lock tube 6 is just round, in two cylinder locks 10 all are coated on, sees Fig. 5.In order to allow another bicycle car owner be connected with pair lock 2 butt joints of this car easily at main lock 1 with oneself, the outer bottom land of the lock tube of secondary lock 2 extends to form a sleeve 13 along the limit, make it and to slide along connecting rod 5, adapt to different variable in distance between car and the car with the length that changes secondary lock 2.

Use the utility model can be with several, tens, hundreds of ... bicycle (no matter whether the car owner is familiar with) all side by side locks together, make the robber can't steal any bicycle, and for the car owner, though who car owner first or after arrive, only need main lock and the secondary car that just can take oneself easily away of locking with key breakdown oneself.In order to prevent to ride the time spent, major and minor lock rocks, and major and minor lock can be snapped in respectively in the Spring Card that is fixed on the back fork of bicycle bar of a side separately.

The utility model compared with the prior art, have the design ingenious, theftproof performance is good, and is easy to use, chain knot Structure also can make storing cycle compactness, orderly, has both saved parking space, can safeguard the appearance of the city again.
