[0003] In the prior art, the adjustment part uses structures such as Velcro and elastic bands to adjust the tightness.

[0004] However, as the number of times or the time spent using Velcro and elastic bands increases, their adhesive strength and elasticity will weaken or even fail, making it impossible to adjust the size of the cuffs. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable snap fastener whose adjustment performance will not fail.

[0006] To achieve the above objectives, this utility model provides an adjustable snap fastener, comprising:

[0007] A slide rail, wherein multiple limiting blocks are provided along the length direction;

The slide rail passes through the mounting groove. The top wall of the female buckle has a deformation groove that passes through the first end and the second end. A mounting part is provided in the middle of the deformation groove. The mounting part is used to engage with the male buckle. The first end is also provided with a deformable adjusting arm. The adjusting arm has a locking part on the side facing the mounting groove. The locking part and the side wall of the mounting groove form an engaging part. The limiting block is locked in the engaging part by the locking part.

[0011] Furthermore, the free end of the adjusting cantilever is provided with a protrusion facing the mounting groove, and the protrusion and the side wall of the adjusting cantilever facing the mounting groove constitute the locking part.

[0012] Furthermore, the distance of the limiting block along the length of the slide rail is less than or equal to the distance between the two groove walls of the locking part.

[0013] Furthermore, the deformation groove is linear.

[0014] Furthermore, the male buckle includes a buckle face and a button bead, with the button bead being engaged and installed in the buckle face.

[0015] Furthermore, the tail end of the button bead is provided with a mounting claw, which engages and is installed in the buckle surface.

[0016] Furthermore, the mounting portion is circular, and the diameter of the mounting portion is smaller than the diameter of the bead.

[0017] Furthermore, the slide rail is provided with at least three limiting blocks at different positions along its length, and two of the limiting blocks are at the same length.

[0018] Furthermore, the width of the adjusting cantilever gradually decreases in the outward direction along the deformation groove.

[0019] Furthermore, this utility model also provides a garment, including fabric and an adjustable snap fastener as described in any of the above claims, wherein the slide rail is disposed on the fabric and the male snap fastener is disposed on the fabric at one end of the slide rail.

[0020] Compared with existing technologies, this utility model provides an adjustable snap fastener with the following advantages: By providing an elastic adjusting arm on the female snap, the pinching or releasing of the adjusting arm drives the locking part below it to fix or adjust the upper limit block of the slide rail, thereby fixing or moving the position of the female snap on the slide rail.

[0036] like Figures 1 to 8 As shown, an adjustable snap fastener 100 according to a preferred embodiment of the present invention includes: a slide rail 1, wherein a plurality of limiting blocks 11 are provided along the length direction of the slide rail 1; a male snap fastener 2; and a female snap fastener 3.

[0037] One of the adjustable snap fasteners 100 includes a slide rail 1, a male snap fastener 2 and a female snap fastener 3. The female snap fastener 3 moves on the slide rail 1, and the male snap fastener 2 is engaged in the female snap fastener 3.

[0038] See Figure 7 and Figure 8As shown, this utility model embodiment also provides a garment, including fabric and an adjustable snap fastener 100, wherein the slide rail 1 is disposed on the fabric, and the male buckle 2 is disposed on the fabric at one end of the slide rail 1.

[0039] Specifically, as is known from the background art, in the field of button technology, the demand for adjusting the tightness of clothing is increasing, and currently, adjustment devices such as Velcro and elastic bands are used to adjust the tightness. However, after repeated use, the adhesive force between the hooks of the Velcro and the fleece will weaken, and the elasticity of the elastic band may fail.

[0040] The garment described in this application allows for adjustment of tightness without altering the garment's shape, such as at the cuffs, collar, or waistband, enabling users to adjust the circumference of the cuffs, collar, or pants according to changes in their body shape. The slide rail 1, female snap 3, and male snap 2 have a simple structure and are easy to install. The two ends of the slide rail 1 are sewn to the collar, and the male snap 2 is fixed to the other side of the collar. The adjusting arm 34 of the female snap 3 is pinched to move the female snap 3 to the desired position, and then the male snap 2 is fastened into the female snap 3, thus securing the two sides of the collar together. The four-piece snap 100 of this embodiment is lightweight and thin, requires minimal installation conditions, is simple to attach, and does not require specialized sewing machines, reducing production costs and improving economic efficiency. In terms of aesthetics, it offers a variety of styles and novel designs. Furthermore, its adjustment function is self-adjusting and its elasticity does not weaken with increased use.

[0041] See Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, specifically, the slide rail 1 is flat and long, and multiple protruding limiting blocks 11 are provided on the slide rail 1. The limiting blocks 11 are arranged along the length direction of the slide rail 1. The limiting blocks 11 can be cuboids or cubes. The limiting blocks 11 restrict the female buckle 3 to a certain position to achieve the purpose of fixing the female buckle 3.

[0042] Thus, by setting a female buckle 3 that can move on the slide rail 1, the tightness of the cuff can be adjusted.

[0043] See Figures 1 to 5As shown, specifically, the female buckle 3 is made of an elastic material, such as rubber, silicone, polyurethane (PU), or elastomers (TPE, TPU, etc.). The female buckle 3 has a first end and a second end, and the female buckle 3 has a mounting groove 31 that passes through the first end and the second end. The slide rail 1 passes through the mounting groove 31. The top wall of the female buckle 3 has a deformation groove 32 that passes through the first end and the second end. A mounting part 33 is provided in the middle of the deformation groove 32. The mounting part 33 is used to engage with the male buckle 2. The first end is also provided with a deformable adjusting cantilever 34. A locking part 35 is provided on the side of the adjusting cantilever facing the mounting groove 31. The locking part 35 and the side wall of the mounting groove 31 form an engaging part 36. The limiting block 11 is locked by the locking part 35 in the engaging part 36.

[0044] It should be noted that in this application, the first end of the female buckle 3 refers to the position where the adjustment cantilever 34 is provided on both sides of the deformation groove 32, and the second end refers to the position where the adjustment cantilever 34 is not provided on both sides of the deformation groove 32.

[0045] Specifically, the mounting groove 31 passes through the first and second ends of the female buckle 3. The width of the mounting groove 31 is slightly larger than the width of the slide rail 1. The height of the mounting groove 31 is the same as the height of the slide rail 1 without the limit block 11.

[0046] Specifically, the deformation groove 32 is formed from the top wall of the female buckle 3 and extends through the first and second ends of the female buckle 3. The female buckle 3 is symmetrical about the deformation groove 32. An adjusting cantilever 34 is provided at one end of the deformation groove 32, and no other structure is provided at the other end of the deformation groove 32. When the female buckle 3 is fixed on the slide rail 1, the side walls at both ends of the deformation groove 32 are parallel. When it is necessary to move the female buckle 3, the adjusting cantilever 34 can be engaged to achieve this. During this process, the distance between the side walls of the deformation groove 32 at the first end decreases, and the distance between the side walls gradually increases from the first end to the second end, with the distance between the side walls of the deformation groove 32 at the second end being the largest. After the adjustment is completed, the adjusting cantilever 34 is released. Since the female buckle 3 is made of elastic material, its side walls can return to a parallel state. If it cannot return to a parallel state, the two adjusting cantilever 34 can be pushed outward in the deformation groove 32 to achieve a parallel side wall state.

[0047] Specifically, a mounting part 33 is provided in the middle of the deformation groove 32, and the mounting part 33 is used to connect with the male buckle 2. Since the part of the male buckle 2 that is mounted on the mounting part 33 is spherical or cylindrical, the sidewall of the mounting part 33 is curved.

[0048] Specifically, the adjusting arm 34 is located at the first end of the female buckle 3, protruding from the outer wall of the female buckle 3 for easy gripping during use. This allows for easy operation of the adjusting arm 34 to change the state of the female buckle 3. The states of the female buckle 3 include fixed and movable states. During use, by pinching the adjusting arm 34 at the first end, the female buckle 3 is prevented from engaging with the limiting block 11, thus moving the female buckle 3. By releasing the adjusting arm 34 or pushing it outward, the female buckle 3 engages with the limiting block 11, thus fixing the female buckle 3.

[0049] Specifically, the adjusting cantilever 34 is provided with a locking part 35 on the side facing the mounting groove 31. That is, the locking part 35 is located at the lower end of the adjusting cantilever 34, and there is a gap between the locking part 35 and the inner wall of the female buckle 3, at the position of the engaging part 36. When the female buckle 3 is in the fixed state, the deformation groove 32 is in a parallel state. At this time, the locking part 35 presses the limiting block 11 against the inner wall of the female buckle 3, and the engaging part 36 formed by the locking part 35 and the inner wall of the female buckle 3 clamps the limiting block 11, thereby preventing the limiting block 11 from moving and thus fixing it. When the female buckle 3 is in the moving state, the engaging part 36 formed by the locking part 35 and the inner wall of the female buckle 3 becomes larger, and the limiting block 11 is not stuck between the locking part 35 and the inner wall, thereby allowing the female buckle 3 to move.

[0050] In some embodiments, the free end of the adjusting cantilever 34 is provided with a protrusion on the side facing the mounting groove 31, and the protrusion and the side wall of the adjusting cantilever on the side facing the mounting groove 31 constitute the locking part 35.

[0051] Specifically, the locking part 35 is concave, with the groove of the locking part 35 facing the side wall of the adjusting member. When the locking part 35 is concave, the groove of the locking part 35 faces the side wall of the adjusting member. The distance between the two groove walls of the locking part 35 can be the same as the length of the limiting block 11 along the slide rail 1, or the distance between the two groove walls of the locking part 35 can be greater than the length of the limiting block 11 along the slide rail 1. This arrangement can restrict the limiting block 11 between the locking part 35 and the inner side wall of the female buckle 3. At the same time, the two protruding edges of the groove are relatively short and do not need to completely overlap with the limiting block 11. They only need to protrude a small portion to lock the limiting block 11 into the engaging part 36.

[0052] This embodiment of the utility model improves the stability of the female buckle 3 on the slide rail 1 by setting the locking part 35 to a concave shape, thereby preventing the female buckle 3 from being easily moved.

[0053] In some embodiments, the distance of the limiting block 11 along the length of the slide rail 1 is less than or equal to the distance between the two groove walls of the locking part 35.

[0054] Specifically, the limiting block 11 can be restricted between the locking part 35 and the inner wall of the female buckle 3.

[0055] In some embodiments, the deformation groove 32 is linear.

[0056] In addition, other shapes of deformation grooves 32, such as arcs, should also be included in the scope of this embodiment. During the installation process, it is sufficient that the distance between the two side walls of the deformation groove 32 is less than the distance between the mounting portions 33 for mounting the male buckle 2. With this configuration, the male buckle 2 can be locked in the mounting portion 33 without detaching from the mounting portion 33 into the deformation groove 32.

[0057] See Figure 6 As shown, in some embodiments, the male buckle 2 includes a buckle face 21 and a button 22, the button 22 being engaged and installed in the buckle face 21.

[0058] Specifically, the male buckle 2 is a device that fastens onto the female buckle 3. The male buckle 2 and the female buckle 3 are fixed together by the button 22 of the male buckle 2 being fixed to the mounting part 33 of the female buckle 3. The buckle face 21 is disc-shaped, with a recess on one side. The head of the button 22 is spindle-shaped, and the tail of the button 22 can be directly installed into the recess. That is, the installation is completed by matching the size of the tail of the button 22 with the size of the recess. The buckle face 21 and the button 22 are located on both sides of the fabric of the garment. The button 22 passes through the fabric and is installed in the buckle face 21 to fix the male buckle 2 onto the garment.

[0059] In some embodiments, the tail end of the button bead 22 is provided with a mounting claw 23, which engages with the buckle surface 21.

[0060] Specifically, the mounting claw 23 at the tail of the button bead 22 is curved, and the mounting claw 23 is bent outward from the middle position of the button bead 22. When the button bead 22 is installed onto the buckle surface 21, the mounting claw 23 is locked inside the buckle surface 21.

[0061] In some embodiments, the mounting portion 33 is circular, and the diameter of the mounting portion 33 is smaller than the diameter of the bead 22.

[0062] Specifically, during the process of fastening the male buckle 2 to the mounting part 33 of the female buckle 3, the head of the button 22 of the male buckle 2 presses the mounting part 33 of the female buckle 3, causing the mounting part 33 of the female buckle 3 to deform outward, thereby inserting the button 22 into the mounting part 33, thus completing the operation of fastening the male buckle 2 to the female buckle 3.

[0063] In some embodiments, the slide rail 1 is provided with at least three limiting blocks 11 at different positions along its length, and there are two limiting blocks 11 at the same length.

[0064] Specifically, since the female buckle 3 has a symmetrical structure with respect to the deformation groove 32, it is provided with two adjusting cantilever 34, two locking parts 35 and two engaging parts 36. In order to enable the female buckle 3 to be stably installed and connected to the slide groove, two limiting blocks 11 are provided at the same length position of the slide groove so that the two limiting blocks 11 can be locked between the engaging parts 36.

[0065] In some embodiments, the width of the adjusting cantilever 34 gradually decreases in the outward direction along the deformation groove 32.

[0066] Specifically, the shape formed by the gradually decreasing width of the adjusting cantilever 34 is designed to be easy for the operator to hold by hand. The operator can quickly complete the adjustment without the aid of tools, and according to the principle of torque, the force used by the operator can also be relatively small.

[0067] The working process of this utility model is as follows: the slide rail 1 can be installed by passing through the mounting groove 31 of the female buckle 3. By pinching or releasing the adjusting cantilever 34 of the female buckle 3, the locking part 35 at its lower end is moved to the middle or outward, so that the limiting block 11 of the slide rail 1 is disengaged or locked from the engaging part 36, so that the female buckle 3 is moved to a suitable position on the slide rail 1. Then, the male buckle 2 is fastened into the mounting part 33 of the female buckle 3, thus completing the adjustment and fixing of the tightness.

[0068] Sew the two ends of the slide rail 1 to the neckline, fix the male buckle 2 on the other side of the neckline, pinch the adjusting arm 34 of the female buckle 3 to move the female buckle 3 to the desired position, and then fasten the male buckle 2 into the female buckle 3, thereby fixing the two sides of the collar together.

[0069] In summary, this utility model embodiment provides an adjustable snap fastener and garment. Its slide rail, female snap fastener, and male snap fastener have a simple structure, are easy to install, and can be moved on the slide rail to adjust the distance between it and the male snap fastener, thereby achieving different tightness adjustments according to needs. It is convenient to operate during use, will not lose its elasticity with the increase of use, has a long service life, is inexpensive, and is aesthetically pleasing and not exposed.

[0070] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
