Description

Multiple lockable bicycle locks

The present invention relates to a bicycle lock which can be locked by a plurality of links, in particular to a bicycle lock which can provide a bicycle seat quick release handle and an external object interlocking lock, thereby preventing the bicycle seat cushion and the front and rear wheels or other objects attached to the vehicle. It is stolen and easy to lock and unlock.

According to the bicycle, it is convenient to adjust the height of the seat cushion, and the replacement of the front and rear wheels. Usually, the quick release handle is used as the connecting component in the part connected with the frame, so as to facilitate the assembly and replacement operations, although these quick release The handle can bring great convenience, but it also has some new problems. When the bicycle is parked outside, the thief can easily remove the seat cushion and the front and rear wheels from the frame by releasing the quick release handle. To prevent the bicycle from being stolen, the owner will purchase a bicycle lock as an anti-theft device for these vehicles.

However, the problem lies in that most of the bicycle locks currently available on the market are mostly locked for the whole vehicle. The front and rear wheels can be worn by the steel cable to achieve the anti-theft lock operation, but in the seat cushion part. Because there is no space to wear, some owners can only use the quick release link of the quick release handle, and remove the seat cushion and carry it with it when parking, which is very inconvenient. For this reason, the industry has developed a so-called quick release lock, which directly adds a lock head to the quick release handle to lock the seat cushion. However, the structure of the quick release lock is limited to the anti-theft of the seat cushion, and other vehicle parts such as The anti-theft of the front and rear wheels and the whole vehicle is not applicable; therefore, for the purpose of anti-theft, it has to be added to Less than one or more locks are not only difficult to lock, but the cost of purchasing locks also increases, and where too many locks should be placed during riding is also a problem.

In view of this, the creator of this case has undergone many research and improvement, and finally completed a bicycle lock with multiple interlocking locks. The purpose of this case is to provide a bicycle that can provide bicycle seat cushion quick release handle and external object link lock. The lock is used to prevent the bicycle seat cushion and the front and rear wheels or other objects attached to the vehicle from being stolen, and the locking and unlocking operations are convenient.

The outer locking member B is provided with a fixing head B1 at one end thereof and is fixed to a fixing slot A4 of the main body 1. The fixing head B1 is connected to one end of the body B0 (the winding body B0 is a steel cable or a chain). The lockable body B0 is connected to a latch B2 at the other end for insertion into the latch insertion hole A5 of the body 1.

The outer connector 3 is correspondingly wedged with the connecting portion 112 of the main body 1 , and is provided with two limiting slots 32 , and a wedge portion 31 is disposed on each side thereof, corresponding to the clamping slot 114 wedged in the connecting portion 112 . .

With the composition of the above structure, during the locking operation (as shown in the third, fourth, fifth, and seventh figures), the body 1 and the socket 2 are first connected to the seat cushion 91 of the bicycle 9. Fast The first insertion hole A2 and the second insertion hole A3 are simultaneously inserted into the first insertion hole A2 and the second insertion hole A3, because the first engagement tooth row 222 and the second card are inserted. The dentition row 232 is a unidirectional helical tooth row, and the first engaging tooth row 222 is unidirectionally clamped by the first internal tooth row 42 as it advances inward, and the second engaging tooth row 232 is subjected to the first The two internal tooth rows 45 are unidirectionally clamped and pushed to a position where the first limiting hole edge 111 and the second limiting hole edge 21 completely meet each other. At this time, the quick release handle 92 is received by the body 1 and the sleeve. The bracket 2 is surrounded by the wedge portion 31 of the connecting portion 112, and then the wheel 93 of the bicycle 9 is wound around the body B0 of the outer locking member B ( After the front wheel and the rear wheel, the lock bolt B2 of the outer lock member B is inserted into the latch insertion hole A5 of the body 1, and the second steel ball C2 is displaced into the card slot B21 of the lock bolt B2 to form a lock. The first clamping block 6 is no longer engaged by the second steel ball C2. At this time, the second spring S2 pushes the first clamping block 6 to be displaced by its return elastic force, and rotates the side of the driving rod 52. The protrusion 523 is correspondingly inserted into the first groove 43 To restrict the displacement of the push rod 4, the body 1 and the sleeve 2 are in a locked state, and the first eccentric column 522 of the driving rod 52 is interlocked with the second clamping block 7 to make the first A ball limiting slot 72 forces the first steel ball C1 to be locked into the limiting slot 32 of the outer connector 3 to form a lock, and finally the key K is pulled out of the key insertion hole, thereby completing the locking operation, thereby preventing the thief from opening. The quick release handle 92 prevents the seat cushion from being stolen, and the outer lock member B can be worn around the wheel 93 of the bicycle 9 (such as the front and rear wheels), or other vehicle-mounted objects, or the entire bicycle 9 can be locked in the parking. On the column to prevent theft.

In addition, the external component 3 can be a vehicle accessory such as a fender, an illumination warning lamp holder, etc., for example, when the external component 3 is an illumination warning lamp holder (as shown in the seventh figure), the connection of the bicycle lock A can be wedged. The portion 112 is used to generate a warning effect; and the external member 3 can also be a part of the lock body L1 of a U-shaped lock L (as shown in the eighth and ninth views), thereby being fixed in the bicycle lock A of the present invention. The connecting portion 112 is provided to accommodate the storage of the U-shaped lock L.

As shown in the tenth figure, the key insertion hole is first inserted into the key insertion hole by the key K, and the lock core 51 is rotated to the unlocking position to interlock the driving rod 52 to withdraw the side protrusion 523 from the first groove 43, The push rod 4 is no longer restricted. At this time, the first spring S1 is displaced by the return elastic force of the push rod 4, and the first engaging tooth row 222 is no longer locked with the first internal tooth row 42. The second engaging tooth row 232 is no longer engaged with the second internal tooth row 45, and the socket seat 2 can be pulled away from the first insertion hole A2 and the second insertion hole A3 of the body 1 while the driving The second eccentric post 524 of the rod 52 is displaced outward by interlocking the first clamping block 6, so that the second steel ball C2 enters the second steel ball limiting slot 62 and is disengaged from the locking slot B2 of the locking bolt B2. The first eccentric post 522 of the driving rod 52 is displaced by the second clamping block 7 to cause the first steel ball C1 to enter the first steel ball limit. The slot 72 is disengaged from the locking slot 32 of the outer connector 3 so that it can be detached from the connecting portion 112 to complete the unlocking operation.

In summary, the present invention provides a plurality of interlocking bicycle locks, which provide a bicycle seat quick release handle and an external object interlocking lock, thereby preventing the bicycle seat cushion and the front and rear wheels or other vehicle-mounted objects from being stolen, and The lock and unlocking operation is convenient, and the multiple locks can be used to solve the lack of the conventional bicycle lock, and the technical means of the creation is none of the prior art, and thus the novelty and progressive requirements of the new patent are unique.

The specific embodiments set forth in the present disclosure are merely for convenience of explanation of the technical content of the present invention, and the present invention is not limited to the above embodiments, and does not exceed the spirit of the present invention and the following patent application scope. In the case of the implementation of the various changes, still belongs to the scope of this creation.
