Description

Technical Field

[0001] The utility model relates to the technical field of trip equipment, more specifically to a telescopic trip structure. Background Art

[0002] The pull cord is the component that controls the zipper, and the user uses it to assist in controlling the zipper's opening and closing. However, existing pull cords are all fixed in length, which can make it difficult for the user to control the zipper during movement due to the pull cord being too long, causing certain inconvenience to the user. Therefore, a structure with a retractable pull cord is needed to facilitate the user's opening and closing of the zipper. To address this issue, the inventors have proposed a retractable pull cord structure. By integrating a rotating ring and a limiting ring into the pull cord, the length of the pull cord can be quickly adjusted, achieving a simple and effective retraction effect and greatly improving the practicality of the pull cord.

[0003] To address the issue of the inability to adjust the length of a pull cord, a Chinese patent (Granted Publication No.: CN210747612U) discloses a retractable and adjustable clothing pull cord. The utility model comprises a housing, wherein the left and right sides of the housing inner wall are provided with a slide groove, and the lower surface of the housing inner wall is fixedly connected to the lower surface of a plastic block via a first spring. The left and right sides of the plastic block are respectively slidably connected within the two slide grooves, and the front of the plastic block is fixedly connected to the back of a jumping bean button via a second spring. The jumping bean button is engaged within a limiting hole provided in the front of the housing. The utility model arranges a first spring within the housing. When a user presses the jumping bean button, the tension of the first spring, through the plastic block, drives the pull cord to retract into the housing, thereby bringing the housing and the locking member closer together. At this time, two limiting rods automatically engage in the two limiting grooves, securing the housing and the connecting member so that both do not swing when the user moves, thereby bringing convenience to people during use.

[0004] This solution still has some shortcomings in application. Since the pull cord used in the matching clothing zipper is small in size and limited in length, if the pull cord is only pulled downward from the top of the pull cord for adjustment, the adjustment length is limited, and it is easy to fail to meet the demand for pull cord adjustment. At the same time, if the pull cord is to be able to be adjusted to a longer length, it is also necessary to consider the effective retraction of the pull cord, otherwise the problem of the pull cord being entangled will easily occur. Therefore, it is necessary to improve the structure of the pull cord so that it can be quickly and easily adjusted in length, and can overcome the above-mentioned limitations and further improve the practicality of the pull cord.
