Description

Technical Field

[0001] This utility model relates to the technical field of cycling equipment, and in particular to a quick-release buckle. Background Technology

[0002] In cycling, bicycles are widely used as a primary mode of transportation. However, traditional bicycle designs do not consider the cyclist's need for convenient storage of personal belongings such as mobile phones, documents, and wallets, leading to numerous inconveniences during actual use. To address this issue, various cycling bags that can be mounted on bicycle frames have emerged on the market. However, existing cycling bags typically can only be directly fixed to the frame or completely detached, lacking a quick-release feature. When cyclists need to leave their vehicles, they can only remove the items from the cycling bag one by one and carry them manually, unable to quickly remove the entire cycling bag and use it directly as a handbag. This design is not only cumbersome but also reduces the practicality and convenience of cycling bags, failing to meet the diverse needs of cyclists. Therefore, how to design a cycling bag buckle that allows for quick detachment and reattachment, ensuring it is both securely fixed to the bicycle frame and easily removed and carried when the cyclist leaves, has become an urgent technical problem to be solved. Utility Model Content

[0003] The purpose of this invention is to provide a fastener that can be quickly assembled and disassembled, so as to overcome the shortcomings of the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A quick-release buckle includes an upper buckle and a lower buckle. The upper buckle is used to install on a cycling bag, while the lower buckle is fixed to a bicycle frame. The upper buckle has a slidably mounted pin, which is slidably connected to the upper buckle via a main spring, and the end of the pin is designed with a rounded corner. When the pin contacts the lower buckle, its rounded end face is compressed and displaced; after assembly, the pin springs back under the force of the main spring, completing the engagement with the second fastening part of the lower buckle. Furthermore, the upper buckle has a fastening interface, and a slightly raised anti-fastening strip is fixed at the bottom of the fastening interface for engaging with the first fastening part of the lower buckle.

[0006] Particularly, the lower buckle includes a fixed counter buckle and a soft rubber pad, which is fixedly arranged at the bottom of the fixed counter buckle to enhance the anti-skid performance. The fixed counter buckle is provided with a first buckle part and a second buckle part integrally formed and extending obliquely upward at both ends, respectively. The first buckle part is buckled with the reverse buckle stop bar, and the second buckle part is buckled with the latch. In order to improve the stability after assembly, a positioning boss extending downward is arranged at the bottom of the upper buckle, and the middle part of the fixed counter buckle is recessed inward to form a reverse buckle groove matched with the positioning boss. After assembly, the positioning boss is abutted in the reverse buckle groove to limit the position of the fixed counter buckle, preventing it from moving or deviating.

[0007] Further, the upper buckle is composed of a bottom shell and an upper shell, which are fixedly assembled by screws to form a buckle interface. A pull rod is slidably arranged in the bottom shell and covered by a cover plate. One end of the pull rod is symmetrically provided with a pair of reset guide frames buckled with guide pins integrally formed on the bottom shell, and a reset spring is arranged inside. The other end of the pull rod extends outward through the bottom shell to form a handle, and pulling the pull rod can drive the latch to move to release the buckling with the second buckle part, thereby achieving quick disassembly. After the pull rod is loosened, the pull rod is automatically reset under the action of the reset spring to restore the initial state.

[0008] Particularly, a pair of symmetrically arranged guide grooves are arranged at both inner sides of the pull rod, and both ends of the latch are inserted into the guide grooves. When the pull rod is pulled, the guide grooves correspondingly pull the latch to move in the sliding direction, thereby releasing the buckling with the second buckle part. In addition, a positioning column is arranged at the middle part of one end of the latch, and the positioning column is sleeved with a main spring, both ends of the main spring being abutted against the inner wall of the bottom shell and the side wall of the latch, respectively, to provide elastic support for the main spring.

[0009] Further, the utility model also includes a design scheme for enhancing the fixing effect. In the second embodiment, a pair of straps are added between the upper buckle and the lower buckle, which are sleeved between the upper buckle and the lower buckle to further enhance the fixing ability of the buckle on the bicycle frame. This design is particularly suitable for bumpy roads or high-intensity riding scenes to ensure that the buckle will not loosen during riding.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] Firstly, the cooperation of the latch and the second buckle part and the quick release design of the pull rod realize the quick assembly and disassembly of the cycling bag, greatly improving the convenience of use. Secondly, the cooperation of the positioning boss and the reverse buckle groove ensures the stability of the upper buckle and the lower buckle after assembly, avoiding loosening or deviation. Thirdly, the cycling bag can be quickly removed from the bicycle frame by the buckle and used as a handbag, meeting the needs of cyclists when leaving the car. Finally, the strap design in the second embodiment further enhances the fixing ability of the buckle on the bicycle frame, suitable for different scenes and use requirements.
