Description

Technical Field

[0001] This utility model relates to zippers, and more specifically to a new type of zipper. Background Technology

[0002] In modern life, zippers, as an extremely common connecting component, are widely used in clothing, bags, tents, and many other fields, greatly facilitating people's daily lives. Since its inception, although the basic structure and working principle of the zipper have undergone improvements, the core has remained largely unchanged. The pull handle plays a crucial role in the use of the zipper. By operating the pull handle, people move the zipper head along the zipper belt, achieving the engagement and disengagement of the teeth, thus completing the opening and closing action of the zipper.

[0003] However, existing zipper designs have certain limitations in terms of the pull handle, the most prominent being that the handle cannot be detached. In practical use, this non-detachable handle causes many inconveniences for users. For example, when the pull handle wears or becomes damaged due to long-term use, or when users want to replace it with a handle that has a different appearance and function according to personal preference, the connection structure between the handle and the zipper head makes it difficult to remove the handle from the zipper head for individual replacement. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a new type of zipper, which has the advantage of having a detachable handle connected to the zipper head for easy replacement.

[0027] The following describes the common knowledge about zippers:

[0028] A zipper is a fastener used to connect or separate the openings of an article, composed of two toothed chain belts and a puller that moves the chain belts to engage or separate their teeth. It is widely used in clothing, bags, tents and other articles, playing the role of opening and closing, and fixing. The principle of zipper is mainly based on the following points:

[0029] Tooth engagement principle: The two chain belts of the zipper are respectively arranged with many corresponding teeth, and the shape and size of these teeth are precisely designed. When the puller moves along the chain belt, the special structure inside the puller will force the teeth of the two chain belts to engage with each other, forming a tight connection, thereby closing the opening of the article. This tooth engagement can withstand a certain pulling force to maintain the closed state.

[0030] Inclined surface and wedge principle: The design of the puller utilizes the principle of inclined surface and wedge. The front end of the puller is usually a wedge-shaped structure, which gradually separates the teeth of the two chain belts when the puller moves forward, creating conditions for the engagement or separation of the teeth. At the same time, the inclined surface structure inside the puller guides the teeth to accurately engage or disengage each other, ensuring the smooth operation of the zipper.

[0031] The connection relationship and working principle between the puller 11 and the chain belt 12 have been disclosed in the anti-pinch zipper patent with patent number 202111506942.3. This application mainly improves the pull handle, and the connection relationship and working principle between the puller 11 and the chain belt 12 belong to common knowledge and will not be repeated here.

[0032] As shown in Figures 1-4 , this example can achieve the effect that the pull handle can be detached and replaced separately.

[0033] Due to the zipper slider 11 and the two chain belts 12, the slider 11 is arranged on the two chain belts 12, and the slider 11 controls the connection or separation of the two chain belts 12. The fixed ring 1 is arranged on the slider 11 and can be integrally formed with the slider 11 or fixed on the slider 11 by other means, such as the fixed ring 1 being tightly embedded in the groove on the slider 11 by interference fit. The detachable pull handle is rotatably connected to the fixed ring 1. The user controls the up and down movement of the slider 11 by pulling the pull handle, thereby controlling the connection or separation of the two chain belts 12. For more detailed working principle, see the anti-pinch zipper patent with patent number 202111506942.3, which is common knowledge and will not be repeated here. When the pull handle is worn out or damaged due to long-term use, or the user wants to replace the pull handle with different appearance and function according to personal preference, it can be detached and replaced separately to avoid wasting resources.

[0034] As shown in Figures 8-10 , this example can achieve the effect of easily replacing the pull handle.

[0035] The pull handle is composed of a holding part and a rotating part. The holding part is the end of the pull handle away from the fixed ring 1, and is used for the user to pull with his hand, so that the user pulls the slider 11 by pulling the holding part with his hand. The rotating part is the end of the pull handle close to the fixed ring 1, and is used for rotatably connecting the entire pull handle to the fixed ring 1 and also can be detached from the fixed ring 1. Since the rotating part of the pull handle is provided with a spring body 13 on both sides of the end away from the holding part, the two spring bodies 13 have elasticity, and are made of metal materials with certain elasticity, such as spring steel and copper alloy. The ends of the two spring bodies 13 that are not connected can separate from each other under the action of external force, and restore to each other under the action of elastic force after the external force is removed. The ends of the two spring bodies 13 that are not connected are provided with a cylindrical body 14, which can be integrally formed with the spring body 13 or fixed on the spring body 13 by other conventional means. The two cylindrical bodies 14 are detachably rotatably connected to the fixed ring 1. When the two spring bodies 13 separate from each other, the distance between the two cylindrical bodies 14 increases, thereby making it easier to install and remove the two cylindrical bodies 14 from the fixed ring 1, and thereby making it easier to replace the pull handle. A tension spring 15 is arranged between the two spring bodies 13, so that the two spring bodies 13 always have a tendency to approach each other, thereby making the two cylindrical bodies 14 always have a tendency to approach each other, and making the two cylindrical bodies 14 stably inserted into the fixed ring 1, thereby avoiding the two cylindrical bodies 14 from easily separating from the fixed ring 1.

[0036] As shown in Figures 1-3 and 5, this example can achieve the effect of allowing the user to pull the zipper more easily at different angles and positions.

[0037] Since the rotating part of the pull handle is detachably connected with the rotating shaft 3 at one end away from the holding part, the rotating shaft 3 is rotatably connected with the fixed ring 1, since the pull handle can be rotatably connected with the fixed ring 1 through the rotating shaft 3, and then the user can more easily pull the zipper at different angles and positions. The rotating shaft 3 can be detached from the rotating part of the pull handle, and then the entire pull handle can be easily detached from the fixed ring 1 after the rotating shaft 3 is detached, so that the pull handle can be easily detached and replaced.

[0038] As shown in Figure 5 , this example can achieve the effect of allowing the pull handle to be easily detached and replaced.

[0039] Since the pull handle includes two side rods 4, a plurality of connecting rods 5 are integrally formed between the two side rods 4, and the two ends of the rotating shaft 3 are respectively inserted into the end portions of the two side rods 4 in a clearance fit, one end of the two side rods 4 near the fixed ring 1 is the rotating part of the pull handle, and the other end is the holding part of the pull handle. The rotating shaft 3 can be detached from the two side rods 4, and then the entire pull handle can be easily detached from the fixed ring 1 after the rotating shaft 3 is detached, so that the pull handle can be easily detached and replaced.

[0040] As shown in Figures 1-3 and 5, this example can achieve the effect of preventing the rotating shaft 3 from being separated from the two side rods 4.

[0041] Since the two ends of the rotating shaft 3 are provided with a blocking cap 2, the two ends of the rotating shaft 3 are blocked to prevent the rotating shaft 3 from sliding relative to the two side rods 4, and to prevent the rotating shaft 3 from being separated from the two side rods 4. At least one of the blocking caps 2 is detachably connected to the rotating shaft 3, such as both blocking caps 2 being inserted into the two ends of the rotating shaft 3 in an interference fit, thereby preventing the rotating shaft 3 from being separated from the two side rods 4. Alternatively, one of the blocking caps 2 is integrally formed with the rotating shaft 3, and the other blocking cap 2 is inserted into the other end of the rotating shaft 3 in an interference fit. When the two side rods 4 are to be detached from the fixed ring 1, at least one of the blocking caps 2 is pulled off the rotating shaft 3 by overcoming the frictional resistance of the interference fit by external force, thereby removing the blockage of the two side rods 4, so that the pull handle can be detached and replaced.

[0042] As shown in Figures 1-3 and 5-7, this example can achieve the effect of adjusting the total length of the pull handle.

[0043] Since the zipper further includes a rear plate 6, the rear plate 6 is uniformly provided with a plurality of groove seats 10, and the plurality of connecting rods 5 are inserted into the plurality of groove seats 10. Taking two connecting rods 5 as an example: the two connecting rods 5 can be inserted into different two groove seats 10 on the rear plate 6, thereby adjusting the length of the side rod 4 and the rear plate 6, and thereby adjusting the total length of the pull handle. Everyone has different preferences for the length of the pull handle, and the adjustable pull handle can meet the personal use habits and comfort requirements, improving the user experience.

[0044] As shown in Figures 1-3As shown in Figs. 5-7, this example can achieve the effect of preventing the rear plate 6 from falling off the two side rods 4 during use.

[0045] Since the upper side cover of the plurality of slots 10 has a front plate 9, the front plate 9 can cover the plurality of slots 10, thereby preventing the two connecting rods 5 from being separated from the corresponding two slots 10 and preventing the rear plate 6 from falling off the two side rods 4 during use.

[0046] As shown in Figs. 5-7, this example can achieve the effect of preventing the rear plate 6 from falling off the two side rods 4 during use. Figures 1-3 Figures 1-3 As shown in Figs. 5-7, this example can achieve the effect of preventing the rear plate 6 from falling off the two side rods 4 during use.

[0047] Since the end of the rear plate 6 is integrally formed with a recess 7, the recess 7 is provided with a socket, and the end of the front plate 9 is fixed with a plug 8, the plug 8 is inserted into the recess 7 in interference fit. By inserting the plug 8 into the recess 7 in interference fit, the rear plate 6 and the front plate 9 are connected as one, and the plug 8 inserted into the recess 7 in interference fit makes the rear plate 6 and the front plate 9 not separated by a small force.
