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 insufficient. Moreover, if the bag is installed in front of the handlebars, it will not only affect the overall controllability of the bicycle, but also cause safety concerns for the rider.

[0003] CN201512051U discloses a bicycle side bag buckle assembly structure, which consists of a hook seat and a clamping seat fixed to the upper and lower parts of the rear side of the bag body; wherein the hook seat has a hook on each of the left and right sides of the base plate, and a movable hook body is provided between the two hooks, which can be hooked and fixed to the side rod of the rear rack of the bicycle; and an axial hole is provided in the center of the horizontal rod of the lower clamping seat, and a buckle rod rotatable along the axis is axially engaged with the axial hole, and the buckle rod can be clamped between the rod bodies of the rear rack support rod, thereby enabling the side bag to be firmly mounted on the side of the bicycle rack side rod and can be quickly removed when not in use. The technical solution adopted by the aforementioned clip to hook onto the side rod of the bicycle rack is that a hook is provided on each of the left and right sides of the base of the hook seat, and a movable hook body is provided between the two hooks. The hook seat and the side rod of the bicycle rack are hooked and clamped by the movable hook body provided between the two hooks. During the up and down shaking, there are no fastening components at both ends, and the stress is concentrated on the middle movable hook body, which can easily cause excessive fatigue of the components of the movable hook body and seriously affect the service life of the movable hook body. Summary of the Invention

[0004] In order to overcome the defects of the prior art, the utility model provides a bicycle side-hanging bag buckle, comprising: a cross bar supported by two support seats, two adjustable hooks arranged on the cross bar, and a carrying strap; the cross bar has a polygonal cross section; the hook comprises a main hook, a rotating buckle and a spring; one end of the main hook is provided with a hook body for hanging with the side bar of the bicycle rack, and the other end is provided with a cross bar through hole for cooperating with the cross bar for limiting the position, and an elastic groove is provided to adjust the tightness of the cooperation between the main hook and the cross bar; an adjusting connecting rod is provided in the middle of the main hook, and two-way limiting protrusions are provided at both ends of the adjusting connecting rod, and a two-way spring column is provided in the middle; a vertical supporting surface and an oblique supporting surface are provided at the bottom of the two-way spring column; an adjusting hook is provided at one end of the rotating buckle to cooperate with the adjusting connecting rod, and the other end of the rotating buckle is provided with a frame limiting block and a pull rod that are jointly clamped with the hook body of the main hook The bicycle rack sidebar has a vertical stop on one side of the adjustment hook and a diagonal stop on the other side. A spring-loaded post protrudes downward from the bottom of the frame limit block, one end of the spring being embedded in the spring-loaded post and the other end being nested in the bidirectional spring-loaded post. When the pull rod is pulled and the rotating buckle is rotated so that the spring presses against the vertical support surface on the adjustment link, the rotating buckle becomes parallel to the inner side of the main hook, the frame limit block is hidden within the main hook, and the buckle is in the open state, allowing a bag attached to the buckle to be removed from the bicycle rack sidebar. After the main hook is hooked to the bicycle rack sidebar, the pull rod is pulled and the rotating buckle is rotated so that the spring presses against the diagonal support surface on the adjustment link. The rotating buckle rotates inwardly of the main hook, causing the frame limit block to extend from the main hook and, together with the hook body, enclose the bicycle rack sidebar. The buckle is locked, and the bag attached to the buckle is locked to the bicycle rack sidebar. In the aforementioned open and locked states, the vertical stop and the diagonal stop cooperate with the bidirectional limit protrusions to limit the rotation direction of the rotating buckle. The pull rod has handle holes at its end, and a handle is secured to each of the two holes. Pulling the handle simultaneously unlocks the buckle, and the bag can be lifted upwards, making it very convenient to operate. The support base has rivet holes at its bottom for riveting the support base to the bag body; the support base has crossbar holes at its top, into which both ends of the crossbar are secured. This utility model utilizes a rotating buckle and a main hook that rotate and elastically fit, providing a secure lock, stable performance, easy unlocking, and convenient hooking and hooking.
