[0044] 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.

[0045] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0046] In the description of the present invention, it is necessary to understand that the terms "upper center" and "lower center", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0047] The utility model aims to provide an adjustable zipper, which solves the problem that the uppermost button of a shirt cannot be tightened or is inconvenient to tighten.

[0048] It should be noted that in this embodiment, the direction of X in the drawings is defined as the first direction, the direction of Y is defined as the second direction, and the directions of X and Y are opposite, for example, when X is clockwise, Y is counterclockwise.

[0049] See also Figure 1 and Figure 2 To achieve the above-mentioned purpose, the utility model provides an adjustable zipper, including a chain 2 and a pull body slidably connected to sprocket teeth 21 spaced apart in the extending direction of the chain 2, the pull body including a slider base 1, a limit assembly and a button base.

[0050] The slider base 1 can be slidably connected to the chain teeth 21, and two spaced side plates 11 are provided at the end of the slider base 1 away from the chain teeth 21; the chain 2 can adopt a single chain 2, that is, the slider base 1 is only slidably connected to the single chain 2, and the position of the slider base 1 on the chain 2 can be changed by pulling the slider base 1.

[0051] The limiting assembly includes a fixing portion 31, a groove portion 32 and a handle portion 33 connected to the fixing portion 31 and the groove portion 32. The fixing portion 31 is rotatably connected to the side plate 11, and an end of the fixing portion 31 away from the handle portion 33 is provided with a locking portion 311 which can be rotated along a first direction to between adjacent sprocket teeth 21 to limit the sliding of the slider base 1 relative to the sprocket teeth 21 after being moved to a preset position; the fixing portion 31, the groove portion 32 and the handle portion 33 are preferably an integrated structure to enhance the structural strength of the limiting assembly and avoid deformation of the limiting assembly during the pulling process. At the same time, it can reduce the assembly of related parts, reduce the difficulty of assembly, and improve production efficiency under large-scale production.

[0052] Among them, the selection of the preset position can be selected according to each person's requirement for tightness, or it can be a certain range of the position of the slider machine base 1 on the chain 2. For example, when user A likes a looser collar of a shirt, etc., he can pull down the slider machine base 1 to the middle and lower part of the chain 2, so that when the following button bottom piece is connected to the corresponding button top piece 5, the collar is looser; when user B likes a looser collar of a shirt, etc., he can pull up the slider machine base 1 to the middle and upper part of the chain 2, so that when the following button bottom piece is connected to the corresponding button top piece 5, the collar is tighter.

[0053] The button bottom piece is connected to the groove portion 32 and can be snapped onto the button top piece 5 that matches the button bottom piece. Usually, the chain 2 is sewn to the fabric 8 through a cloth tape 6, and a top piece is provided on the fabric 8 at the other end. The two pieces of fabric 8 can be connected by the cooperation between the button bottom piece and the button top piece 5. The button bottom piece slides on the chain 2 through an adjustable zipper to adjust the distance between the two pieces of fabric 8.

[0054] The slider base 1 can be used to make the adjustable zipper slide along the extension direction of the chain 2. The limit assembly is rotatably connected to the side plate 11 provided on the slider base 1 through the fixed portion 31, so that the lock portion 311 provided at one end of the fixed portion 31 can be rotated along the first direction to between adjacent sprockets 21 to limit the sliding of the slider base 1 relative to the sprockets 21 after being moved to the preset position. The groove portion 32 on which the button base is installed is connected to the fixed portion 31 through the handle portion 33, and the button base can be clamped with the corresponding button top portion 5 to achieve the fastening of the button. With this arrangement, the position of the button base can be adjusted through the slider base 1, which can solve the problem that the buttons at the top of the shirt cannot be loosened or are inconvenient to loosen.

[0055] In this embodiment, the groove portion 32 is a plate structure, and the groove portion 32 is provided with a first through hole 321 whose axis is perpendicular to the plate structure. To facilitate the opening of the first through hole 321, the first through hole 321 can be set in the middle of the plate structure. The button base includes a base 41, a connecting member 42, a fixing member 43 and a blocking member 44. The connecting member 42 is passed through the first through hole 321 and one end is vertically connected to the middle of the base 41; an installation position is provided inside the fixing member 43, and the installation position is connected to the end of the connecting member 42 away from the base 41, so that the base 41 and the fixing member 43 are relatively fixed on both sides of the groove portion 32, which is used for axially limiting the button base relative to the slider machine base 1.

[0056] Among them, the blocking member 44 is connected to the bottom of the fixing member 43, and the cross-sectional diameter of the blocking member 44 perpendicular to the axis of the first through hole 321 is larger than the cross-sectional diameter of the fixing member 43 perpendicular to the axis of the first through hole 321, so that when the fixing member 43 is inserted into the button top member 5, the blocking member 44 can abut against the bottom of the button top member 5.

[0057] In one embodiment, first planes parallel to each other are provided on the opposite sides of the side panels 11, and the side panels 11 are provided with second through holes with axes perpendicular to the first planes, and the axial directions of the two second through holes are consistent. Both sides of the fixing portion 31 are provided with cylindrical first protrusions 312 adapted to the corresponding second through holes, and the first protrusions 312 installed in the second through holes can rotate relative to each other to realize the relative rotation of the side panel 11 and the fixing portion 31. The cylindrical first protrusion 312 can also be set as a rotation axis passing through the fixing portion 31, and the fixing portion 31 can rotate relative to the rotation axis, and the rotation axis can rotate relative to the second through hole, so as to reduce the wear of the fixing portion 31 during rotation.

[0058] In another embodiment, first planes parallel to each other are provided on the opposite sides of the side panels 11, and the side panels 11 are provided with a cylindrical second protrusion with an axis perpendicular to the first plane. The fixing portion 31 is provided with a third through hole for rotational cooperation of the second protrusion. The third through hole can also be set as countersunk holes located on both sides of the fixing portion 31 and with consistent axial directions, which can also realize the rotational connection between the side panel 11 and the fixing portion 31.

[0059] It should be noted that the length of the remaining part of the above-mentioned fixing part 31 except the first protrusion 312 on the axis of the second through hole should be smaller than the distance between the two side panels 11 to realize the rotation of the fixing part 31 between the side panels 11. Preferably, the thickness of the fixing part 31, the groove part 32 and the handle part 33 are consistent, so as to facilitate being made by stamping the same plate body.

[0060] In the present embodiment, considering that the locking portion 311 can move to the gap between adjacent sprockets 21 by rotation, it is preferred that an inclined surface is provided on the opposite side of the sprocket 21 to provide the space required for the locking portion 311 to rotate, and the locking portion 311 is provided with an arc surface adapted to the outer wall of the sprocket 21, so that when the locking portion 311 is rotated in the second direction, it can be disengaged from the gap between adjacent sprockets 21 without getting stuck during the rotation process, and the fixing portion 31 and the groove portion 32 are perpendicular to each other, and when the fixing portion 31 is vertically arranged so that the locking portion 311 is stuck in the gap between adjacent sprockets 21, the groove portion 32 on which the button bottom piece is installed can be parallel to the fabric 8, so as to facilitate the clamping of the button bottom piece with the button top piece 5 provided on another fabric 8, and the distance between the middle of the arc surface and the groove portion 32 on the axis of the first through hole 321 is smaller than the distance between the two ends of the arc surface and the groove portion 32 on the axis of the first through hole 321.

[0061] See also Figures 7 to 10 When the limiting component rotates along the first direction, it drives the locking step to rotate along the first direction until the locking portion 311 rotates to be perpendicular to the fabric 8 used to install the chain 2. At this time, the slider base 1 is in a locked state and cannot slide along the extension direction of the chain 2; when the limiting component rotates along the second direction (the opposite direction of the first direction), it drives the locking step to rotate along the second direction until the locking portion 311 disengages from the gap between adjacent chain teeth 21. At this time, the slider base 1 is in an unlocked state, and the slider base 1 can slide relative to the chain 2 to adjust the position of the slider base 1 on the chain 2.

[0062] See also Figures 3 to 6The adjustable zipper in this embodiment also includes a cloth tape 6. Both ends of the chain 2 are provided with stoppers 22 connected to the cloth tape 6 through ribs 7. A plurality of sprockets 21 spaced apart from each other along the extension direction of the chain 2 are provided between the two stoppers 22. All sprockets 21 are U-shaped structures, and the slider base 1 is provided with a U-shaped shell 12 capable of accommodating the sprockets 21. The cross-sectional dimension of the stopper 22 perpendicular to the extension direction of the U-shaped shell 12 is greater than the cross-sectional dimension of the U-shaped shell 12 perpendicular to its own extension direction, so as to limit the slider base 1 from being separated from the chain 2.

[0063] Among them, when the sprocket 21 is U-shaped, it is convenient for the slider base 1 to slide along the extension direction of the chain 2. The specific shapes of the sprocket 21 and the U-shaped housing 12 can be adjusted according to actual conditions to achieve the above purpose.

[0064] See also Fig.11 In addition, the present embodiment also includes a garment equipped with the above-mentioned adjustable zipper, which also has the beneficial effects of the above-mentioned adjustable zipper. The garment also includes a cloth 8 provided with a button top piece 5, and the button top piece 5 includes a contact piece 51 and a positioning piece 52 located on both sides of the cloth 8. The positioning piece 52 is used to fix the contact piece 51 to the cloth 8, and the contact piece 51 can be snapped into the fixing piece 43 of the button bottom piece. The specific method and process of installing the contact piece 51 and the positioning piece 52 on the cloth 8 can refer to the existing technology, and will not be described in detail here. In addition, the button top piece 5 can be multiple, and the interval between adjacent button top pieces 5 can be set according to actual needs, as long as the above-mentioned purpose can be achieved.

[0065] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0066] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0067] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
