Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a zipper which is convenient for replacing a zipper head. Background Art

[0002] Zipper is a common connection method, usually used to close items and clothing. It is mainly composed of two or more metal or plastic chain teeth, which bite each other to form a continuous channel to hold items. The main function of the zipper is to connect two items conveniently and quickly, while providing sealing. No tools or fasteners are required. The connection can be completed by sliding the zipper head along the zipper strip. Zippers can not only be used to connect items, but also to fix items to prevent them from slipping. Usually, the zipper head is detachable from the head of the zipper strip for easy replacement;

[0003] However, if the zipper pull is used for a long time and becomes worn, it may get stuck when sliding on the zipper teeth, which makes it inconvenient to replace the zipper pull.

[0004] In order to solve the above problems, the present application proposes a zipper that is easy to replace the zipper head. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] like Figure 1-4 As shown, the utility model provides a zipper that is convenient for replacing zipper heads, comprising two zipper strips 1;

[0022] In this embodiment, zipper teeth 2 are connected to opposite sides of two zipper strips 1 , and a zipper head body 3 slidably connected to the zipper teeth 2 is disposed between the two zipper strips 1 .

[0023] In this embodiment, the zipper head body 3 is provided with an opening disposed toward the zipper teeth 2, and a lubricating member 4 for lubricating the zipper teeth 2 is installed in the opening. The lubricating member 4 includes a lubricating shaft cylinder 41, a through lubricating chamber is provided in the lubricating shaft cylinder 41, an elastic cone thorn portion 42 inserted into the lubricating chamber is installed on the lubricating shaft cylinder 41, a sealing film 43 is connected to the bottom of the lubricating chamber, and lubricating oil is provided in the lubricating chamber. The elastic cone thorn portion 42 includes a cone thorn rod 421, an end block 422, a first spring 423 and a cone head 424. The cone thorn rod 421 is inserted into the lubrication chamber, and the end block 422 is installed at one end of the cone thorn rod 421. The first spring 423 is sleeved on the cone thorn rod 421 and is located between the lubrication shaft cylinder 41 and the end block 422, and the two ends of the first spring 423 are respectively connected to the lubrication shaft cylinder 41 and the end block 422. The cone head 424 is installed at one end of the cone thorn rod 421 away from the end block 422, and the cone head 424 is located in the lubrication chamber.

[0024] It should be noted that: in order to facilitate the replacement of the zipper head body 3, when the zipper head body 3 slides on the zipper teeth 2 and gets stuck, the end block 422 can be pressed so that the cone head 424 at the bottom of the cone rod 421 pierces the sealing film 43, and the lubricating oil in the lubrication chamber drips onto the zipper teeth 2, and then the zipper head body 3 is pulled to evenly distribute the lubricating oil on the zipper teeth 2, so that the zipper head body 3 can slide on the zipper teeth 2 more smoothly, reduce jams, and facilitate people to replace it. This structure evenly distributes the lubricating oil on the zipper teeth 2 by pressing the lubricating part 4, so that the replacement process of the zipper head body 3 is smoother and the difficulty and time of replacement are reduced.

[0025] In the specific embodiment, two elastic limiting parts 44 are also included. The inner walls on both sides of the lubricating shaft cylinder 41 are provided with receiving channels. The two elastic limiting parts 44 are respectively installed in the two receiving channels, and the elastic limiting parts 44 are used to limit the cone head 424. The elastic limiting part 44 includes a second spring 441. The two second springs 441 are respectively installed in the two receiving channels. The two second springs 441 are both installed with a limiting block 442 located in the lubricating chamber at the opposite end. The two limiting blocks 442 are both formed with an inclined surface at the opposite side.

[0026] It should be noted that: in order to prevent people from accidentally touching the end block 422 and causing the sealing membrane 43 to be punctured, the first spring 423 between the end block 422 and the lubrication shaft cylinder 41 can play a first layer of buffering role. When the cone head 424 at the bottom end of the cone rod 421 approaches the sealing membrane 43, the end block 422 can play a certain blocking role, and the limit block 442 compresses the second spring 441, and the second spring 441 plays a second layer of buffering role. This structure can effectively prevent the sealing membrane 43 from being punctured due to accidental touching of the end block 422.

[0027] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
