Bicycle seat cushion lock structure

The present invention relates to a bicycle lock, and more particularly to a bicycle seat lock structure which is mounted on a bicycle seat cushion and has the effect of preventing theft of the seat cushion, the wheel and the whole vehicle.

According to the bicycle, in order to facilitate the adjustment of the height of the seat cushion and the replacement of the front and rear wheels, the quick-release is usually used as the connecting component in the part connected with the frame, so as to facilitate the assembly and replacement operations, although these quick-releases It can bring a lot of convenience, but it also has some new problems. When the bicycle is parked outside, the thief can easily release the seat cushion and the front and rear wheels by the quick release, in order to prevent the bicycle. When the car is stolen, the owner will buy a bicycle lock as an anti-theft device for these cars.

However, most of the existing bicycle locks on the market are only for the locking of the whole vehicle. The front and rear wheels can be worn by the steel cable to achieve the anti-theft lock operation, but the seat cushion is not available. The space that is worn around, so that some owners can only use the quick release, the seat cushion is removed and carried with it when parking, so it is very inconvenient. For this reason, the industry has developed a quick release lock, directly set a quick release on the quick release of the entire wrap, but this quick release lock is directly exposed and large, not only will damage the beauty of the bicycle, and It is easy to cause obstacles when riding a bicycle. In addition, it can only lock the quick release, prevent the seat cushion from being stolen, and cannot achieve the anti-theft of the front and rear wheels and the whole vehicle. At the same time, the purpose of the front and rear wheels and the whole vehicle anti-theft should be achieved. Can only be added at least More than one pair of locks, not only the trouble of use, but also the cost of purchasing locks.

The creator has the effect of destroying the beauty of the bicycle in view of the conventional quick release lock. It is a hindrance to bicycle riding, and it can only prevent the seat cushion from being stolen. It can not simultaneously achieve the shortcomings of the front and rear wheels and the whole vehicle anti-theft. It is the idea of creation and trial, and the design and test sample test by many parties. After the revision was improved, the creation was finally designed.

The present invention provides a bicycle seat cushion lock structure which is assembled in a bicycle seat The seat bow of the pad comprises: a lock head, a joint seat and a steel cable, wherein the lock head is provided with a lock seat, a linkage member and a card bead in a lock case, and the lock seat is fixed to the lock case The lock seat is provided with a lock core and a lock hole, and the lock core is combined with a driving member, and the linkage member can be laterally slid by the driving member, and the card bead can be restricted or released according to the sliding of the linkage member. Restricting, the binding seat is fixed on the locking head, the binding seat has at least one clamping hole, and the clamping hole is suspended by the clamping hole of the bicycle seat cushion, the cable has a predetermined length, and one end is provided with a locking bolt. The other end is provided with a ring, and the bolt can be locked in the lock hole of the lock seat through the lock case, and the ring can be used to form a fixed ring for the lock bolt to provide a circle around the wheel, the parking column, and the like. Things.

The main purpose of this creation is that the lock head set is suspended from the bicycle seat cushion. The seat bow is hidden under the bicycle seat cushion, so it does not damage the beauty of the bicycle, and does not cause obstacles when the bicycle is riding.

Another purpose of this creation is that the lock head set is suspended from the bicycle seat cushion. The seat bow is matched with a steel cable that is locked at one end and the lock head, and is wound around a fixed object such as a wheel and a parking column to achieve theft prevention of the seat cushion, the wheel and the whole vehicle.

Please refer to the first figure, the second figure and the third figure. The bicycle seat cushion lock structure is set on the seat bow of the bicycle seat cushion, and comprises: a lock head 1, a joint seat 2 and a steel cable 3 The lock head 1 is disposed in a lock housing 11 and is provided with a lock seat 12, a linkage member 13 and a card bead 14. The lock seat 12 is fixed to the lock case 11, and the lock seat 12 is provided with a lock core 15 And a locking hole 121 is coupled to the driving core 151 and a torsion spring 152. The torsion spring 152 is configured to have an elastic force of automatic recovery when the locking core 15 rotates, and the linking member 13 can be driven by the driving member 151. The slider 14 is restrained or unrestricted by the sliding of the linkage member 13. The coupling seat 2 has a first seat body 21 and a second seat body 22, and the first seat body 21 is consolidated. The second base 22 is oppositely coupled to the first base 21, and at least one clamping hole 23 is formed between the second base 22 and the first base 21 (this embodiment is Two clamping holes 23), the cable 3 has a predetermined length, one end is provided with a locking bolt 31, and the other end is provided with a ring 32, and the locking bolt 31 is provided with an annular locking groove 311.

When using the locking operation, please refer to the fourth and fifth figures, and the binding seat 2 is clamped by the two clamping holes 23 to the seat bow 41 of the bicycle seat cushion 4, and the locking bolt 31 of the steel cable 3 is worn. Winding ring 32, the cable 3 is formed into a fixed ring 3A, and the fixing ring 3A is used to wrap around the bicycle wheel (such as the front wheel, the rear wheel), the parking column and the like, and then the locking bolt 31 is inserted through the lock housing 11 Lock seat 12 The locking hole 121 is inserted into the slot 311 of the latch 31 by the card bead 14 and is locked by the linkage 13 to lock the latch 31 so that the latch 31 cannot be disengaged from the lock seat 1 to prevent the seat cushion 4 from being removed. The wheel is stolen, and the entire bicycle can be locked in a fixed object such as a parking column.

When the unlocking operation is performed, the lock core 15 is inserted into the lock core 15 and the lock core 15 is driven to drive the drive. The piece 151 drives the linking member 13 to slide laterally to release the restriction of the ball 14 from the slot 311 of the locking bolt 31, so that the locking bolt 31 can be withdrawn from the locking hole 121 of the locking seat 12 to complete the unlocking operation.

From the structure of the above specific embodiment, the following benefits can be obtained:

1. The bicycle seat cushion lock structure of the present invention has a lock head 1 which is suspended from the seat cushion 41 of the bicycle seat cushion 4 by a joint seat 2, and is hidden under the bicycle seat cushion 4, thereby not damaging the bicycle exterior shape. Beautiful, and will not cause obstacles when cycling.

2. The bicycle seat cushion lock structure of the present invention has a lock head 1 which is suspended from the seat bow 41 of the bicycle seat cushion 4 by a joint seat 2, and a cable 3 which is locked with one end and the lock head 1 is wound around the lock head 3 Fixing objects such as wheels and parking columns prevent the seat cushion 4 and the wheels from being stolen. At the same time, the entire bicycle can be locked in a fixed object such as a parking column, and the utility is improved, and the cost of purchasing the lock is reduced.

In summary, this creation has indeed reached a breakthrough structure, and has improved content of creation, while at the same time achieving industrial use and progress.
