[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] The core of the utility model is to provide a slider structure, which is easy to assemble, not limited by the influence of materials, has good structural integrity and reliability, avoids skin getting stuck in the slider body, and ensures reliable protection effect. Another core of the utility model is to provide a zipper including the slider structure.

[0036] The slider structure provided by the utility model includes a slider body 2, a track member 1 and a pull tab 3. Please refer to Figure 1-2 .

[0037] The slider body 2 is the main part of the slider structure, and the track member 1 is hinged to the slider body 2. Specifically, the track member 1 includes a horizontal end 11 and an arc end 12. The horizontal end 11 is hinged to the tail end of the slider body 2, and the hinge can be realized by a pin. The tail end here corresponds to the lowermost end of the zipper when it is pulled and closed.

[0038] One end of the horizontal end 11 is provided with an arc end 12, that is, one end of the horizontal end 11 is the arc end 12, and the other end is an end hinged to the tail end of the slider body 2. The arc end 12 is bent inward relative to the slider body 2 to cover the head end of the slider body 2. During the movement of the slider body 2, due to the covering effect of the arc end 12, even if the slider body 2 is pulled faster, the arc end 12 will first contact the skin to prevent the skin from being stuck in the slider body 2.

[0039] The pull tab 3 slides on the track member 1 and can drive the slider body 2 to move up and down, corresponding to the opening and closing operation of the zipper. During this process, the track member 1 remains connected to the slider body 2, and the pull tab 3 drives the two to move together. There is no interference with the movement of the pull tab 3, so the opening and closing operation can be carried out smoothly.

[0040] In this embodiment, the track member 1 and the slider body 2 are hinged, and are not limited by the materials of the two, which facilitates assembly and processing, simplifies the processing difficulty, and ensures that the track member 1 has a long-term stable and reliable protective effect when the pull tab 3 moves.

[0041] Preferably, the arc end 12 is covered at the head end of the slider body 2 at an angle greater than 90 degrees and less than 180 degrees, so as to prevent the slider body 2 from contacting the skin first and thus achieve a protective effect.

[0042] Optionally, the track member installed on the slider body 2 is easy to install, so the material selection has more flexibility. The material can be metal, injection molding material, or soft injection molding.

[0043] The above-mentioned slider structure includes a slider body 2, a track member 1 and a pull tab 3. The track member 1 includes a horizontal end 11 and an arc end 12. The tail end of the slider body 2 is hinged to the horizontal end 11 of the track member 1 to achieve a connection between the two. One end of the horizontal end 11 is bent inward toward the slider body 2 to form an arc end 12, and the arc end 12 is covered at the head end of the slider body 2; due to the covering effect of the arc end 12, even if the slider 3 is pulled faster, the arc end 12 of the track member 1 will contact the human skin, and the head end of the slider body 2 will not contact the skin, so the skin will not be stuck in the slider body 2. The arc end 12 contacts the human skin, effectively reducing damage to the skin; in addition, the pull tab 3 slides on the track member 1 and drives the slider body 2 to move up and down. Corresponding to the opening and closing operation of the zipper, the pull tab 3, the slider body 2 and the track member 1 are easy to assemble, and the structural integrity and reliability are good. The slider structure is simple to install and process, has good reliability, avoids skin getting stuck in the slider body, and improves the user experience.

[0044] On the basis of the above-mentioned embodiment, a slideway 6 is formed between the slider body 2 and the rail member 1, and an upper limit portion 61 and a lower limit portion 62 are provided at both ends of the slideway 6 respectively. The upper limit portion 61 and the lower limit portion 62 are used to limit the flipping angle of the pull tab 3 so that the top of the pull tab 3 is lower than the top of the rail member 1.

[0045] Please refer to Figure 3-4 The gap between the slider body 2 and the track member 1 forms a slideway 6, and an upper limit portion 61 and a lower limit portion 62 are correspondingly provided at both ends of the slideway 6, and the upper limit portion 61 and the lower limit portion 62 limit the flipping angle of the pull tab 3.

[0046] The pull tab 3 slides in the slide 6. Specifically, the upper limit portion 61 is set at the connection between the horizontal end 11 and the arc end 12. When the pull tab 3 reaches the upper limit portion 61, it is in a vertical state with the slider body 2. The pull tab 3 will not flip upward again, so that the pull tab 3 will not flip to the top of which is higher than the top of the track member 1. When the pull tab 3 is pulled to close, the pull tab 3 will not come into contact with human skin, thereby avoiding scratching the human skin.

[0047] The lower limit portion 62 is set at the lower end of the track member 1. When the zipper needs to be opened, the pull tab 3 will slide to the position of the lower limit portion 62 and drive the slider body 2 to move downward for opening. The pull tab 3 is in a parallel state with the slider body 2 at the position of the lower limit portion 62.

[0048] During the closing operation, if the pull tab 3 has driven the slider body 2 to move up to the correct position, the pull tab 3 is released and the pull tab 3 returns to the position of the lower limit portion 62 under the action of gravity and becomes parallel to the slider body 2 .

[0049] Please refer to Figure 4 The upper limit portion 61 and the lower limit portion 62 limit the rotation range of the pull tab 3 to 0-180°, so as to prevent the pull tab 3 from over-turning and scratching the skin, and make it difficult for the pull tab 3 to turn to the inside of the clothes, so as to facilitate grabbing the pull tab 3.

[0050] On the basis of any of the above embodiments, the bottom surface of the arc end 12 is flush with the lower bottom surface of the slider body 2 .

[0051] Please refer to Figure 2 , Figure 4 The horizontal end 11 of the track member 1 is arranged along the central axis direction on the upper surface of the slider body 2, and the arc end 12 is bent inward relative to the horizontal end 11 and extends to be flush with the lower bottom surface of the head end of the slider body 2. When the pull tab 3 is pulled to the upper limit position 61, the bottom surface of the slider body 2 will contact the skin and will not press against the skin, thereby avoiding scratching the skin.

[0052] It should be noted that the bottom surface of the arc end 12 is flush with the lower bottom surface of the slider body 2. Figure 2 In terms of.

[0053] Based on any of the above embodiments, an elastic sheet 4 is provided on the top of the slider body 2, and the two ends of the elastic sheet 4 are respectively a movable end 41 and a limit end 42. The movable end 41 extends into the inner side of the arc end 12 and can move with the pull tab 3, so that the limit end 42 moves out of or extends into the tooth channel 21 on the slider body 2.

[0054] Please refer to the figure. An elastic sheet 4 is provided on the top of the slider body 2. It should be noted here that the elastic sheet 4 is located between the slider body 2 and the track member 1. When the pull tab 3 is pulled, the movable end 41 can extend into the inner side of the arc end 12 to exert a force on the slider body 2, so that the limit end 42 in the tooth channel 21 on the slider body 2 moves out or extends in.

[0055] Specifically, the elastic sheet 4 here can be regarded as a lever structure as a whole, and the tail end of the slider body 2 is hinged to the track member 1. Therefore, when the pull tab 3 is pulling, a misalignment may occur between the slider body 2 and the track member 1. The misalignment here can also refer to a certain inclination, so that the limit end 42 can be moved into the tooth channel 21; when the pull tab 3 finishes pulling, the limit end 42 can be automatically retracted into the tooth channel 21 with the help of auxiliary parts, such as tension springs, springs, etc., to prevent the slider body 2 from continuing to slide.

[0056] Based on any of the above embodiments, a spring 5 is provided between the movable end 41 and the slider body 2, a clearance groove 13 is provided on the track member 1, and a swing end 43 is provided on the top of the elastic sheet 4. The movement of the pull tab 3 allows the swing end 43 to swing in the clearance groove 13, thereby driving the movable end 41 to compress the spring 5.

[0057] Please refer to Figure 2 An elastic sheet 4 is provided on the top of the slider body 2 , and the elastic sheet 4 specifically includes a moving end 41 and a limiting end 42 , wherein the moving end 41 extends into the inner side of the arc end 12 and a spring 5 is provided between the moving end 41 and the slider body 2 .

[0058] In a specific embodiment, two ends of the spring 5 can be fixed to the moving end 41 and the slider body 2 respectively, and the spring 5 can be compressed or rebounded when the moving end 41 moves.

[0059] In another specific embodiment, one end of the spring 5 is connected to the moving end 41 , and the other end is embedded in the slider body 2 .

[0060] In another specific embodiment, one end of the spring 5 abuts against the moving end 41 , and the other end is fixed in the slider body 2 .

[0061] The movement of the pull tab 3 can drive the movable end 41 to move left and right. In the initial state, the limiting end 42 extends into the tooth channel 21 to limit the movement of the slider body 2.

[0062] Please refer to Figure 2-3When the pull tab 3 moves downward to the lower limit portion 62 to pull the slider body 2, the track member 1 also moves and generates a force, causing the swing end 43 to swing in the clearance groove 13, thereby causing the movable end 41 to move to the right to compress the spring 5. The compression of the spring 5 releases the limit end 42 from the initial state and moves out of the tooth channel 21. At this time, under the force of manual pulling, the slider body 2 can be pulled smoothly. After the manual force disappears, the force generated by the elastic compression of the spring 5 can reset the swing end 43 and the limit end 42 to re-enter the tooth channel 21. At this time, the slider body 2 no longer moves.

[0063] When the pull tab 3 moves upward to the upper limit portion 61 to pull the slider body 2, the track member 1 also moves accordingly and generates a force, causing the swing end 43 to swing in the yielding groove 13, thereby causing the movable end 41 to act to compress the spring 5. The compression of the spring 5 releases the limit end 42 from the initial state and moves out of the tooth channel 21. At this time, under the force of manual pulling, the slider body 2 can be pulled smoothly. After the manual operating force disappears, the compression force of the spring 5 can cause the limit end 42 to extend into the tooth channel 21 again to reset.

[0064] Based on any of the above embodiments, a mounting groove is provided on the slider body 2, one end of the spring 5 is provided between the arc end 12 and the top of the mounting groove, and the other end of the spring 5 abuts against the bottom of the mounting groove.

[0065] Please refer to the figure. In this embodiment, a long strip of mounting groove is provided on the slider body 2. One end of the spring 5 is arranged between the arc end 12 and the top of the mounting groove. In essence, this end of the spring 5 is connected to the arc end 12. The other end of the spring 5 abuts against the bottom of the mounting groove. When the spring 5 is compressed, the mounting groove can limit the deformation direction of the spring 5, thereby ensuring the reliability of its auxiliary unlocking and locking tooth operations.

[0066] Preferably, the length of the spring 5 is slightly greater than the depth of the mounting groove, so as to ensure reliable deformation when the spring 5 is compressed, so as to realize automatic locking of the teeth.

[0067] Based on any of the above embodiments, the distance between the end surface of the head body 2 and the top end surface of the track member 1 is 8-10 mm.

[0068] In this embodiment, the distance a between the end surface of the first end of the slider body 2 and the top end surface of the track member 1 is set to 8-10 mm. Figure 8 , while preventing the skin from getting stuck, it also avoids the problem of unstable center of gravity, ensures the convenience and reliability of the installation of the track member 1, and in addition, avoids the large spacing affecting the sliding of the pull tab 3, ensuring the reliability and smoothness of the pull tab 3 pulling the slider body 2 to open and close.

[0069] On the basis of any of the above embodiments, the outer side of the arc end 12 is an arc, and the inner side of the arc end 12 has an inclined surface to support the limiting movable end 41 .

[0070] Please refer to Figure 1-2 The outer side of the arc end 12 is an arc with a smooth surface, so that it has a better protective effect when in contact with human skin, avoiding scratching the skin and preventing the flesh from getting stuck.

[0071] Preferably, the transition positions between the arc end 12 and the horizontal end 11, as well as the transition position between the arc end 12 and its lower bottom surface are all arc-shaped to prevent scratching the skin.

[0072] The inner side of the arc end 12 has an inclined surface to support the limit moving end 41. Figure 2 The inner side of the arc end 12 has a vertical surface, an inclined surface and a transition surface, wherein the vertical surface and the inclined surface are used for guiding and limiting the moving end 41 when it moves. When the moving end 41 moves to fit with the vertical surface, it cannot move any further and has moved to the leftmost limit. The transition surface on the lower side of the inclined surface is used to limit the downward movement of the moving end 41, ensuring that the moving end 41 can directly and accurately act on the spring 5 to perform the unlocking and locking operations of the slider.

[0073] In this embodiment, the protective effect can be achieved by limiting the outer side of the arc end 12 to be an arc, and the structure of the horizontal end is not limited. Its cross section can be square, trapezoidal or other shapes, such as Figure 7-8 shown.

[0074] On the basis of any of the above embodiments, the track member 1 and the slider body 2 are coaxially arranged, and the width of the track member 1 is smaller than the width of the slider body 2 and larger than the width of the clearance groove 13 on the track member 1 .

[0075] Please refer to Figure 5-6 The central axes of the track member 1 and the slider body 2 coincide with each other, so that the track member 1 is centered as a whole, which is convenient for installation and ensures the stability of the entire component.

[0076] The width b of the track member 1 is smaller than the width of the slider body 2 and larger than the width d of the clearance groove 13. Fig. 9 The width of the track member 1 needs to ensure comfort when in contact with the skin. Therefore, in this embodiment, the width of the track member 1 is limited to avoid being too narrow and pressuring the skin.

[0077] Here, the width b of the track member 1 can be the width of the top of the track member 1 minus the width of the arc end 12; or it can be the width of the entire track member 1. In this case, the track member 1 is an overall square structure, and the width of each part is consistent.

[0078] In addition to the above-mentioned slider structure, the utility model also provides a zipper including the slider structure disclosed in the above-mentioned embodiments, the zipper includes any of the above-mentioned slider structures and two groups of zipper strips 7 corresponding thereto, and when the pull tab 3 is pulled, the minimum spacing between the zipper strips 7 is greater than the width of the track member 1.

[0079] Please refer to Fig. 9 The minimum spacing between the zipper strips 7 when the pull tab 3 is pulled, i.e., the width c of the fan-shaped opening of the teeth of the zipper strips 7 on both sides of the head body 2, limits the width of the track member 1 to b<c, and combined with the above, d<b<c, to avoid the width being too narrow to affect the comfort when in contact with the skin, and to avoid the track member 1 being too wide to affect the smooth pulling of the slider body 2.
