Description

Technical Field

[0001] The utility model relates to the technical field of luggage accessories, and more specifically to an adjustable double-sided pull tab. Background Art

[0002] The pull is a component that controls the zipper. The user uses the pull to assist in controlling the opening and closing of the zipper. Conventional pull structures all consist of a pull head and a pull cord, which is tied to the zipper head via the pull cord. Each zipper is equipped with a pull. This simple structure and function cannot meet the needs of some real-life scenarios. For example, many of the common badminton rackets, tennis rackets, and table tennis rackets we often see are stored together, with left and right slots, each equipped with a zipper and a pull, which can be opened and closed separately. However, during sparring training, both rackets are often taken out or put back together, and opening and closing the zipper separately is somewhat inconvenient. In addition, the length of the pull cord of the existing pull is fixed and cannot be adjusted. There is also the problem that the pull cord is too long or too short, resulting in poor control of the zipper, which brings certain inconvenience to the user. In response to this, the inventors propose an adjustable double-sided pull. A single pull cord can open and close two zippers at the same time, improving convenience. At the same time, the length of the pull cord is adjustable, further enabling the pull cord to better control the opening and closing of the zipper and improving practicality.

[0003] To achieve the goal of controlling the opening and closing of two zippers with one pull, a Chinese patent (authorization publication number: CN217337621U) discloses a zipper lock device and zipper structure. The utility model includes a first pull and a second pull. The first pull includes a first connecting portion and a first locking portion that are interconnected. The first connecting portion is used to connect to one zipper in a two-way zipper, and the first locking portion is provided with a first spiral groove. The second pull includes a second connecting portion and a second locking portion that are interconnected. The second connecting portion is used to connect to the other zipper in the two-way zipper, and the second locking portion is provided with a second spiral groove. When the two zippers in the two-way zipper slide close to each other, the first spiral groove and the second spiral groove can engage with each other to securely connect the first locking portion and the second locking portion. By securely connecting the first locking portion and the second locking portion, the utility model can prevent two zippers that are close to each other from sliding apart and opening the zipper tape of a bag, effectively reducing the risk of losing items in the bag.

[0004] This solution still has some shortcomings in application. Although one pull cord controls two zipper heads, it controls the opening and closing of one zipper. In real life, some scenarios require one pull cord to open and close two zippers at the same time, such as table tennis rackets, badminton rackets and tennis rackets. They are usually a set of two and are used for daily sparring. Therefore, it is more convenient to open and close the two zippers at the same time when taking out and putting in. In addition, it is very important that the length of the pull cord is adjustable. Otherwise, it is easy for the pull cord to be too long or too short, which affects the use of the pull cord. Therefore, the structure of the pull cord needs to be improved so that it can realize the simultaneous control of the opening and closing of the two zipper heads according to the actual usage scenario, and at the same time, the length of the pull cord can be flexibly adjusted to further improve the practicality of the pull cord.
