Description

Technical Field

[0001] This utility model relates to the field of clothing accessories technology, and in particular to a pull tab and a pull head. Background Technology

[0002] Zippers generally consist of teeth, a slider, and top and bottom stops or locking mechanisms. The slider includes a pull body and a tab, which facilitates user operation and acts as an aid. Additionally, to improve the user experience, a cord is often included on the cord. However, the cord is usually secured to the cord by a knot after passing through a hole in the cord. In practice, the cord can easily detach from the cord, affecting normal use. Related technologies have an anti-detachment hole at the rear end of the cord for the cord to pass through. The cord needs to bend when passing through the anti-detachment hole to restrict its position and prevent detachment. However, the inner wall of the anti-detachment hole is a smooth surface, which allows the cord to easily shift upwards under stress, causing it to loosen, shift its position, or even detach from the cord.

[0003] Therefore, how to improve the stability of the rope when it is threaded onto the pull plate is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a pull tab and pull head that can reduce the extent of rope upward movement and the possibility of eventual deviation or loosening, thereby improving the stability of the rope when it is threaded onto the pull tab.

[0005] To achieve the above objectives, this utility model provides a pull tab, including a connecting part and a mounting part connected to the lower end of the connecting part. The connecting part is used to connect a pull body, and the mounting part is used to mount a rope. The mounting part is provided with a first rope hole and an obstruction part provided in the first rope hole. The first opening of the first rope hole is located on the side of the mounting part, and the second opening of the first rope hole is located on the lower end face of the mounting part. The obstruction part protrudes from the arc-shaped inner wall of the first rope hole to contact the rope.

[0006] In one possible implementation, the first rope hole includes a first inner wall connected to the lower end of the first opening and the second opening, and an obstruction portion is provided on the first inner wall.

[0007] In one possible implementation, the obstruction includes a first plane and a second plane that is angled to the first plane. The first plane is parallel to the lower end face of the mounting portion, and a rounded corner is provided at the connection between the first plane and the second plane.

[0008] In one possible implementation, the first rope hole includes a second inner wall connected to the upper end of the first opening and the second opening, the second inner wall being opposite to the first inner wall, and the upper end of the second inner wall being provided with a guide arc surface to adapt to the curved section of the rope.

[0009] In one possible implementation, the lower end of the second inner wall is provided with a third plane, which is perpendicular to the lower end surface of the mounting portion.

[0010] In one possible implementation, the ratio of the distance between the upper end of the first inner wall and the lower end face of the mounting portion to the distance between the upper end of the second inner wall and the lower end face of the mounting portion ranges from 1 / 6 to 2 / 3.

[0011] In one possible implementation, the first opening is shaped like a teardrop, narrower at the top and wider at the bottom.

[0012] In one possible implementation, the mounting part is further provided with two second rope holes, which are spaced apart in the width direction of the mounting part, and both second rope holes are closed structures.

[0013] In one possible implementation, the maximum width of the first opening in the width direction of the mounting portion is greater than the maximum width of the second opening in the width direction of the mounting portion.

[0014] Based on the above, this application also provides a pull head, including a pull body and a pull tab as described in any of the above.

[0015] Compared to existing technologies, the technical solution provided by this utility model has at least the following beneficial effects: During use, the pull tab is connected to the pull body through the connecting part, and the rope pulled by the user passes through the first rope hole provided on the mounting part. Since the first opening of the first rope hole is located on the side of the mounting part, and the second opening of the first rope hole is located on the lower end face of the mounting part, the rope needs to be bent when passing through the first rope hole, which restricts the position of the rope and prevents the rope from detaching from the pull tab. The inner wall of the first rope hole is provided with an obstruction part that protrudes from the arc-shaped inner wall of the first rope hole. When the rope in the first rope hole is subjected to force and moves upward, the obstruction part will block part of the rope, increase the friction force against the rope, thereby reducing the upward movement of the rope and the possibility of eventual deviation or loosening, thus improving the stability of the rope when it is threaded on the pull tab.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] In the description of this utility model, it should be understood that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0032] The purpose of this invention is to provide a pull tab and pull head that can reduce the extent of rope upward movement and the possibility of eventual deviation or loosening, thereby improving the stability of the rope when it is threaded onto the pull tab.

[0033] Please see Figure 1 and Figure 2 To achieve the above objectives, this utility model provides a pull tab, including a connecting portion 100 and a mounting portion 200 connected to the lower end of the connecting portion 100. The connecting portion 100 is used to connect to a pull body 300, so that the pull tab is connected to the pull body 300. The mounting portion 200 is used to mount a rope 400, and the mounting portion 200 is provided with a first rope hole 210 and an obstruction portion 220 provided in the first rope hole 210. The first opening 211 of the first rope hole 210 is located on the side of the mounting portion 200, and the second opening 212 of the first rope hole 210 is located on the lower end face of the mounting portion 200. The obstruction portion 220 protrudes from the arc-shaped inner wall of the first rope hole 210 to contact the rope 400.

[0034] During use, the pull tab is connected to the pull body 300 via the connecting part 100, and the rope 400 for the user to pull passes through the first rope hole 210 provided on the mounting part 200. Since the first opening 211 of the first rope hole 210 is located on the side of the mounting part 200, and the second opening 212 of the first rope hole 210 is located on the lower end face of the mounting part 200, the rope 400 needs to be bent when it passes through the first rope hole 210, which serves to limit the position of the rope 400 and prevent the rope 400 from detaching from the pull tab. The inner wall of the first rope hole 210 is provided with an obstruction part 220 that protrudes from the arc-shaped inner wall of the first rope hole 210. When the rope 400 in the first rope hole 210 is subjected to force and moves upward, the obstruction part 220 will block part of the rope 400, increase the friction force against the rope 400, thereby reducing the upward movement of the rope 400 and the possibility of eventual deviation or loosening, and thus improving the stability of the rope 400 when it is threaded on the pull tab.

[0035] The first opening 211 can be located on either the front or the back of the mounting part 200. When the first opening 211 is located on the front of the mounting part 200, it facilitates the assembly of the rope 400 and the mounting part 200, improving assembly efficiency. When the first opening 211 is located on the back of the mounting part 200, the pull tab has a smooth surface when viewed from the front of the zipper, resulting in a more aesthetically pleasing appearance and a better grip.

[0036] Please see Figure 5 , Figure 6 and Figure 7 The mounting part 200 is also provided with two second rope holes 230, which are spaced apart in the width direction of the mounting part 200. The rope 400 can pass through these two second rope holes 230 to form a transverse fold 410 of the rope 400, and hang the rope 400 on the pull tab. Then, the two vertical rope segments of the rope 400 pass through the first opening 211 of the first rope hole 210 from different directions and exit through the second opening 212 of the first rope hole 210. A stitch 420 is provided between the two vertical rope segments of the rope 400 located outside the pull tab. The stitch 420 connects at least the upper end of the folded rope 400 together to form a closed loop, so that the rope 400 cannot fall off the pull tab. In addition, both second rope holes 230 are closed structures, which can avoid the problem of the rope 400 easily falling off caused by the open structure of the rope hole in the prior art.

[0037] Please see Figure 3 and Figure 4 In one possible implementation, the first rope hole 210 includes a first inner wall 213 connected to the lower end of the first opening 211 and the second opening 212. The first opening 211 of the first rope hole 210 is located on the side of the mounting portion 200, while the second opening 212 of the first rope hole 210 is located on the lower end face of the mounting portion 200. This causes the rope 400 to bend when it passes through the first rope hole 210, thus determining the direction of the first rope hole 210. When the rope 400 passes through the first rope hole 210, it will be closer to the side of the first rope hole 210 connected to the lower end of the first opening 211 and the second opening 212 due to gravity. That is, the rope 400 will be closer to the first inner wall 213 of the first rope hole 210 due to gravity. The obstruction portion 220 is provided on the first inner wall 213, which can more effectively restrict the movement of the rope 400, thereby improving the stability of the rope 400 when it is threaded on the pull tab.

[0038] It is worth mentioning that the shape of the obstruction part 220 can be selected as an edge protrusion with rounded corners. The obstruction part 220 includes a first plane 221 and a second plane 222 set at an angle to the first plane 221. The first plane 221 is the upper end surface of the obstruction part 220 and is parallel to the lower end surface of the mounting part 200. The second plane 222 can be set to be perpendicular to the first plane 221 and extend towards the second opening 212. After the rope 400 is passed through the first rope hole 210, the vertical second plane 222 will not interfere too much with the vertical movement of the rope 400 in the direction of gravity. However, when the rope 400 moves towards the first opening 211 on the side of the mounting part 200, the edge protrusion will interfere more with the rope 400 in the direction of movement towards the first opening 211, thereby preventing the rope 400 from moving upward towards the first opening 211. The connection between the first plane 221 and the second plane 222 is provided with rounded corners to reduce the possibility of cutting the rope 400. The shape and position of the obstruction part 220 can also be adjusted according to the actual situation. For example, the shape of the obstruction part 220 can be set as a cylindrical protrusion. The diameter of the cylindrical protrusion can be adjusted to change the degree of fit between the cylindrical protrusion and the rope 400. The position of the obstruction part 220 can also be set at the edge of the first opening 211 to make the first rope hole 210 more flat and beautiful.

[0039] In one possible implementation, the first rope-passing hole 210 includes a second inner wall 214 connected to the upper end of the first opening 211 and the second opening 212. The second inner wall 214 is opposite to the first inner wall 213. The upper end of the second inner wall 214 is provided with a guide arc surface to adapt to the curved section of the rope 400. The guide arc surface is used to guide the rope 400, making it easier for the rope 400 to pass through the first rope-passing hole 210. The lower end of the second inner wall 214 is provided with a third plane, which is perpendicular to the lower end face of the mounting part 200. This third plane is used to guide the rope 400 from the guide arc surface to the second opening 212, restricting the direction of the rope 400. The interaction of the aforementioned angular protrusion, the aforementioned first inner wall 213, and the aforementioned second inner wall 214 makes it easier for the rope 400 to pass through the first rope-passing hole 210 while preventing the rope 400 from moving upwards. It should be noted that when the second plane 222 is parallel to the third plane, a channel of uniform thickness is formed between the second plane 222 and the third plane, which is used for the rope 400 to pass through the channel from the second opening 212, thereby reducing the possibility of the rope 400 shifting or loosening, and thus improving the stability of the rope 400 when it is threaded on the pull plate.

[0040] In one possible implementation, the ratio of the distance between the upper end of the first inner wall 213 and the lower end face of the mounting portion 200 to the distance between the upper end of the second inner wall 214 and the lower end face of the mounting portion 200 ranges from 1 / 6 to 2 / 3. The distance between the upper end of the first inner wall 213 and the lower end face of the mounting portion 200 refers to the distance in the height direction between the upper end of the first inner wall 213 and the lower end face of the mounting portion 200 when the lower end face of the mounting portion 200 is horizontal. Similarly, the distance between the upper end of the second inner wall 214 and the lower end face of the mounting portion 200 refers to the distance in the height direction between the upper end of the second inner wall 214 and the lower end face of the mounting portion 200 when the lower end face of the mounting portion 200 is horizontal. If the ratio of the distance between the upper end of the first inner wall 213 and the lower end face of the mounting part 200 to the distance between the upper end of the second inner wall 214 and the lower end face of the mounting part 200 is too small (e.g., 1 / 8), it will not effectively limit the rope 400. If the ratio of the distance between the upper end of the first inner wall 213 and the lower end face of the mounting part 200 to the distance between the upper end of the second inner wall 214 and the lower end face of the mounting part 200 is too large (e.g., 7 / 8), it will affect the insertion of the rope 400.

[0041] In one possible implementation, the first opening 211 is teardrop-shaped, narrower at the top and wider at the bottom. The wider bottom region facilitates the insertion of the rope 400, while the edge of the narrower top region blocks the rope 400, restricting its movement and reducing the possibility of it becoming loose. The maximum width of the first opening 211 in the width direction of the mounting portion 200 is greater than the maximum width of the second opening 212 in the width direction of the mounting portion 200. The second opening 212 is smaller than the first opening 211, further restricting the movement of the rope 400.

[0042] In summary, this application provides a pull tab, wherein the connecting portion 100 of the pull tab is used to connect to the pull body 300, thereby connecting the pull tab to the pull body 300. The mounting portion 200 of the pull tab is provided with a first rope hole 210 and an obstruction portion 220 provided within the first rope hole 210. The first opening 211 of the first rope hole 210 is located on the side of the mounting portion 200, and the second opening 212 of the first rope hole 210 is located on the lower end face of the mounting portion 200, for mounting a rope 400. The obstruction portion 220 is provided within the first rope hole 210, protruding from the arc-shaped inner wall of the first rope hole 210 to contact the rope 400. The shape of the obstruction portion 220 is an angular protrusion with rounded corners, and the obstruction portion 220 includes a first plane 221 and a second plane 222 that is angled to the first plane 221. The first plane 221 is the upper end face of the obstruction part 220. The first plane 221 is parallel to the lower end face of the mounting part 200. After the rope 400 is threaded through the first rope hole 210, the vertical second plane 222 does not significantly interfere with the vertical movement of the rope 400 in the direction of gravity. However, when the rope 400 moves towards the first opening 211 on the side of the mounting part 200, the angular protrusion will interfere more with the rope 400 in the direction of movement towards the first opening 211, thus hindering the rope 400 from moving upwards towards the first opening 211. This increases the frictional force against the rope 400, thereby reducing the upward movement of the rope 400 and the possibility of eventual deviation or loosening, thus improving the stability of the rope 400 when threaded onto the pull tab. The connection between the first plane 221 and the second plane 222 is rounded to reduce the possibility of cutting the rope 400.

[0043] Based on the foregoing, this application also provides a zipper puller, including a pull body 300 and a pull tab as described above. During use, when the rope 400 is subjected to force and moves upwards, the obstruction part 220 blocks a portion of the rope 400, increasing the friction against the rope 400, reducing the upward movement of the rope 400 and the possibility of eventual deviation or loosening, thereby improving the stability of the rope 400 when threaded onto the pull tab. The structures of other parts of the zipper puller are described in the prior art and will not be repeated here.

[0044] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0045] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0046] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
