Description

Technical Field

[0001] The utility model relates to a bag buckle for a bicycle, belonging to the field of bag accessories. Background Art

[0002] Driven by environmental protection and energy conservation, and driven by the trend of the times, bicycles are no longer just a means of transportation, but are widely used in commuting, sports, and outdoor leisure activities. However, due to their simple structure, they lack designs for carrying items. To meet the needs of different users, many bicycle bag-shaped buckle structures have been designed on the market for carrying items while riding. However, the buckle structures of common bags are mostly designed in front of the handlebars or above the rear rack. However, due to the limited space available in these two locations, the size of the carrying bag is also restricted. For many users, the storage space of the carrying bag is not enough. Moreover, if the bag is installed in front of the handlebars, it will not only affect the overall controllability of the bicycle, but also pose a safety hazard to the rider. Summary of the Invention

[0003] In order to overcome the defects of the prior art, the utility model provides a bicycle front fork bag buckle, comprising: a fixing seat fixed to the bicycle front fork and a buckle plate riveted to the bag; a locking cavity is provided in the buckle plate, and a locking plate is placed in the locking cavity to lock the buckle plate and the fixing seat.

[0004] The fixing seat is provided with an arc-shaped bottom surface that fits the front fork of the bicycle, and strap holes are provided on both sides of the fixing seat, and the fixing seat is fastened to the front fork of the bicycle by passing straps through the strap holes; a bolt hole is provided in the middle of the fixing seat, and the fixing seat is screwed to the front fork of the bicycle by bolts through the bolt hole; a bottom buckle block is provided at the bottom end of the fixing seat, an upper buckle nail is provided at the upper end, and a limiting convex edge is provided on the top of the upper buckle nail.

[0005] The side of the buckle plate is provided with a rivet hole to rivet the buckle plate to the bag, the bottom end of the buckle plate is provided with a bottom buckle groove that matches the bottom buckle block at the bottom end of the fixing seat, the top of the buckle plate is provided with a top buckle groove that matches the top buckle nail at the top of the fixing seat, and the side of the top buckle groove is provided with a limiting boss that can be engaged with the limiting convex edge at the top of the upper buckle nail; the locking cavity in the buckle plate is provided with: a locking plate shaft, a locking plate guide column, a spring groove and a rotating handle groove; the lower end of the locking plate is provided with a shaft hole, A guide hole is provided on the upper part, a locking spring embedded column is provided on the right side, a rotating handle is provided on the upper end, and a locking tongue is provided on the left front end; one end of a locking spring is embedded in the locking spring embedded column, and the other end is pressed into the spring embedded groove; the rotating shaft hole is embedded in the locking plate rotating shaft, and the guide hole is embedded in the locking plate guide column. The locking plate can rotate around the locking plate rotating shaft under the guidance of the guide hole, and the lock tongue extends into the top buckle groove under the action of the locking spring, pressing the limit boss to realize locking of the buckle plate and the fixing seat. When locking, the bottom buckle groove at the bottom end of the buckle plate is correspondingly engaged with the bottom buckle block at the bottom end of the fixing seat, and the top buckle groove at the top end of the buckle plate is correspondingly engaged with the top buckle nail at the top end of the fixing seat. The lock tongue inserted into the top buckle groove is retracted into the locking cavity under the pressure of the top buckle nail when the top buckle nail enters the top buckle groove, so that the top buckle nail enters the end of the top buckle groove, and then, under the action of the locking spring, it is extended into the top buckle groove again and presses against the limiting convex edge to prevent the top buckle nail from withdrawing from the top buckle groove, thereby realizing the locking of the buckle plate and the fixing seat.

[0006] To unlock, you need to use the rotating handle on the upper end of the locking plate to rotate the locking plate to the left to drive the lock tongue out of the top buckle slot, and then pull it upward to remove the buckle plate from the fixed seat.

[0007] In order to realize convenient unlocking, the first embodiment discloses a method of setting a wrench at the end of the rotating handle, and rotating the locking plate by turning the wrench to drive the lock tongue to exit the top buckle groove.

[0008] The second embodiment discloses an unlocking solution: an inclined groove and a button are provided on the side of the rotating handle. The button is provided with an inclined slider that cooperates with the inclined groove to rotate the locking plate to drive the lock tongue out of the top buckle groove. To cooperate with the button to realize the rotation of the locking plate, a pressing spring embedded groove, guide ribs and limit ribs are provided in the locking cavity. A pressing block is provided at the top of the button to facilitate the user's pressing. A pressing spring embedded column is provided at the bottom of the button. A pressing spring is provided with one end embedded in the pressing spring embedded column and the other end is placed in the pressing spring embedded groove. A guide groove and a limit block are provided at the bottom of the button. The guide groove and the guide rib cooperate to guide the button to slide up and down, and the limit block and the limit rib cooperate to limit the travel of the button when it rebounds.

[0009] The utility model locks the buckle plate and the fixing seat through the locking plate, and the fixing seat can be conveniently fixed on the front fork or crossbar of the bicycle. The disassembly and assembly operations are quite convenient, which expands the application scenarios of the bicycle bag and enriches the optional content of the bicycle bag.
