Description

Technical Field

[0001] The utility model relates to the technical field of clothing parts, in particular to a keyhole structure for leather fabrics. Background Art

[0002] Buttonholes are widely used in various types of clothing. Buttons are connected to different parts of the clothing through buttonholes. The shape and material of buttonholes vary according to the fabric and the shape of the buttons. For leather fabric clothing, due to the limited elasticity and flexibility of the fabric, the buttons installed by extrusion and stitching will damage the leather fabric clothing during use. For special buttons, different buttonholes are required for connection. Therefore, a keyhole structure for leather fabrics is needed.

[0003] After retrieval, the patent number "CN214340382U" provides "The utility model provides a keyhole structure for rough fabrics that can prevent the fabric fibers around the buttonhole from fraying, belonging to the technical field of clothing. It solves the problem of keyhole opening for rough fabrics. The utility model includes: a rough fabric, a buttonhole is arranged on the rough fabric, a keyhole edge line is arranged along the contour of the buttonhole, and a reinforcing line sutured to the rough fabric is arranged in the area covered by the keyhole edge line. The reinforcing line is obtained by running a line along the contour of the buttonhole with a flat head eye device. The utility model uses the organic combination of a flat head eye device and a round head eye device to overcome the problem of fiber fraying caused by keyhole opening for rough fabrics, breaking the limitation that rough fabrics cannot have buttonholes or using press buttons instead. At the same time, the reduction in the use of decorative buttons saves costs. The utility model has the characteristics of simple structure, convenient operation, and cost savings". When in use, through the arrangement of the buttonhole and the keyhole edge line, the rough fabric can have a buttonhole. However, when in use, due to the insufficient toughness and elasticity of the leather material, elastic deformation will cause damage to the leather fabric. At the same time, since the pin on the back of the button is easy to scratch the fabric during installation, the outward-mounted button will also affect the aesthetics of the clothes to a certain extent. During use, it is also easy for the sewing thread to fall off due to friction, damaging the keyhole structure. The aesthetics of this device has limitations during use and is prone to breakage during long-term use, affecting the user experience.

[0004] Therefore, we provide a keyhole structure for leather fabrics to solve the above problems. Summary of the Utility Model

[0024] Please refer to Figure 1-6 , the present invention provides a technical solution: a buttonhole structure for a leather fabric, including an outer placket 1 and a buttoning mechanism 5. A clip 2 is provided at the bottom end of the outer placket 1, a button body 3 is welded to the bottom end of the clip 2, a first cushion layer 4 is provided at the top end of the outer placket 1, and a buttoning mechanism 5 is provided at the top end of the first cushion layer 4;

[0025] The buttoning mechanism 5 includes a buttoning component 51 and a buttonhole component 52. The buttoning component 51 is provided at the top end of the first cushion layer 4, and the buttonhole component 52 is provided between the clip 2 and the button body 3.

[0026] Further, the button fastening assembly 51 includes an outer auxiliary ring 511, a buckle 512, and an inner auxiliary ring 513. The outer auxiliary ring 511 is provided at the top end of the first cushion layer 4. The buckle 512 is provided inside the outer auxiliary ring 511. The inner auxiliary ring 513 is provided inside the buckle 512. The buckle 512 penetrates through the first cushion layer 4. The buckle 512 is adhesively connected to the clip 2. By squeezing the buckle 512 downward, the buckle 512 locks the outer auxiliary ring 511, so that the clip 2 is fixed to the outer front piece 1. At the same time, the buckle 512 locks the inner auxiliary ring 513, further improving the fixing effect. The first cushion layer 4 serves as a protective layer for the outer front piece 1 to prevent damage to the outer front piece 1 when the buckle 512 is squeezed between the outer auxiliary ring 511 and the inner auxiliary ring 513.

[0027] Further, the buttonhole assembly 52 includes an outer auxiliary layer 521, a suture 522, a second cushion layer 523, an inner auxiliary line 524, an outer auxiliary line 525, and an inner front piece 526. The outer auxiliary layer 521 is provided between the clip 2 and the button body 3. The suture 522 is provided on the surface of the outer auxiliary layer 521. The second cushion layer 523 is adhesively connected to the inside of the outer auxiliary layer 521. The inner auxiliary line 524 is provided inside the second cushion layer 523. The outer auxiliary line 525 is provided on one side of the inner auxiliary line 524. The inner front piece 526 is provided at the bottom end of the outer auxiliary line 525. The top and bottom ends of the inner front piece 526 are sutured to the second cushion layer 523 and the outer auxiliary layer 521 by the suture 522. Both the inner auxiliary line 524 and the outer auxiliary line 525 are made of a mixture of polyester fiber and cotton thread. Assisted by the second cushion layer 523, it prevents damage to the inner front piece 526 when the suture 522 penetrates through the inner front piece 526. At the same time, it also increases the contact area between the suture 522 and the inner front piece 526 to prevent the inner front piece 526 from being strained when fastening the button, effectively protecting the inner front piece 526. The outer auxiliary layer 521 reduces the friction of the button body 3 on the inner front piece 526, effectively protecting the second cushion layer 523 and the inner front piece 526. The inner auxiliary line 524 and the outer auxiliary line 525 play a role in limiting the suture 522 to prevent excessive pulling of the inner front piece 526 by the suture 522 during production and causing damage.

[0028] Working principle: First, move the keyhole structure of a leather fabric to the working position. In the first step, stack the outer front piece 1 and the first cushion layer 4, and punch holes corresponding to the snap fastener 512. In the second step, insert and pass the snap fastener 512 through the first cushion layer 4 via the holes. In the third step, place the outer auxiliary ring 511 outside the snap fastener 512, and place the inner auxiliary ring 513 at the bent part inside the snap fastener 512. In the fourth step, squeeze the snap fastener 512 to lock the outer auxiliary ring 511 and the inner auxiliary ring 513 by the snap fastener 512, completing the installation of the buttoning component 51. In the fifth step, make a suitable opening on the inner front piece 526, wrap the second cushion layer 523 around the opening edge of the inner front piece 526, and place the inner auxiliary thread 524 and the outer auxiliary thread 525 between the second cushion layer 523 and the inner front piece 526. In the sixth step, let the outer auxiliary layer 521 complete the wrapping of the second cushion layer 523, and use the sewing thread 522 to stagger and complete the stitching around the inner auxiliary thread 524 and the outer auxiliary thread 525, completing the production of the keyhole component 52. In the seventh step, when the button body 3 pulls the outer front piece 1, assisted by the first cushion layer 4 and the buttoning component 51 together, reduce the pulling force of the snap fastener 512 on the outer front piece 1 to avoid damage to the outer front piece 1. In the eighth step, when buttoning, with the combined action of the outer auxiliary layer 521 and the second cushion layer 523, reduce the friction on the inner front piece 526 and the pulling force of the sewing thread 522 on the inner front piece 526 to avoid damaging the inner front piece 526. In this way, the production and use process of a keyhole structure of a leather fabric are completed.
