Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fasteners, and more specifically to a split plastic buckle. Background Art
[0002] Buckles, commonly known as snap-on buckles, are generally made of plastic and are widely used as connecting components in industrial products such as textiles. They are generally divided into integrated and split structures. The split type generally includes a mother buckle and a child buckle, which are fixed by the child buckle movably fastening to the mother buckle. This combination is used in many luggage and clothing industries. Existing buckles usually have a structure in which the child buckle fastens to the mother buckle. This structure is stable, but it also has the disadvantage of being difficult to adjust. In actual use scenarios, buckles need to be able to adjust the tightness to facilitate user use. For example, open backpacks usually have a cover on the top. When the backpack contains a small amount of items, the cover needs to be tightened, and when the backpack contains a large amount of items, the cover needs to be loosened to better cover the backpack opening. Conventional buckles only achieve the function of covering and fixing, which cannot meet user needs. To address this problem, the inventors have proposed a split plastic buckle. The mother buckle and the child buckle are designed separately, and the child buckle is provided with several limit stops, which can be adjusted for tightness, which can be better applied in actual scenarios.
[0003] In order to effectively cover the backpack and make the cover cloth better cover the backpack opening, a Chinese patent (authorization announcement number: CN220734692U) discloses a multifunctional combined quick fixing device for blasting charges. The utility model includes a backpack charging bag. The interior of the backpack charging bag is composed of nine grids. The top of the backpack charging bag is fixedly connected with a water-repellent cover cloth, and the water-repellent cover cloth is made of cowhide. The bottom of the water-repellent cover cloth is fixedly connected with a backpack cover cloth. A buckle is installed on the top of the water-repellent cover cloth, and a buckle is provided at the bottom of the backpack cover cloth. The buckle and the buckle are arranged accordingly. The utility model effectively covers the backpack opening through the water-repellent cover cloth to prevent objects in the backpack from being disturbed by rain and the like.
[0004] This solution still has some shortcomings in application. Since the objects in the backpack are of different sizes, and the cover cloth and the backpack are fastened with ordinary buckles, when the objects in the backpack are small, the gap between the cover cloth and the two sides of the backpack is large, and the covering effect is not good. When the objects in the backpack are large, the buckles of the cover cloth may not reach the buckles of the backpack, resulting in the cover cloth not being able to cover the bag. At the same time, when the buckle can be adjusted, the convenience of adjustment must also be considered. Otherwise, it is easy for the adjustment method to be inflexible, resulting in a poor user experience. Therefore, it is necessary to improve the structure of the buckle so that it can not only achieve tightness adjustment, but also simple and quick adjustment operation, which can overcome the above-mentioned limitations and further improve the practicality of the buckle.
