The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application and cannot be understood as a limitation of the present application.

[0039] The core of the present application is to provide a kind of super thin four-dog, can effectively avoid the problem of bottom piece thickness too thick.

[0040] In order for those skilled in the art to better understand the technical solutions provided by the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0041] Specifically, please refer to Fig. 1-8, the present application provides a kind of super thin four-dog, including: female buckle assembly 1, female buckle assembly 1 includes first buckle surface 11 and bow cup 12.

[0042] The first buckle surface 11 has a first cavity and is provided with a first opening, the first cavity of the first buckle surface 11 is provided with a first conical gasket 112 and a first buckle surface gasket 111, the first buckle surface gasket 111 is wrapped on the first conical gasket 112 and forms a second cavity. The first buckle surface gasket 111 is provided with a second opening, and the conical surface of the first conical gasket 112 faces the second opening and the first opening. Wherein, the first conical gasket 112 has a conical surface protruding outward, and the first buckle surface gasket 111 is a bent plate, the shape of the bent plate can be improved adaptively according to the shape of the first conical gasket 112 and the inner wall of the first cavity of the first buckle surface 11, as long as the first conical gasket 112 can be limited in the first buckle surface 11 through the first buckle surface gasket 111, and the second opening is opened on the first buckle surface gasket 111, and the second opening is opposite to the first opening and the conical surface of the first conical gasket 112.

[0043] The upper surface of the bow cup 12 is provided with a first assembly column 121, and the lower surface is provided with a third opening for clamping with the male buckle assembly 2. The first assembly column 121 can be inserted into the second opening of the first buckle surface gasket 111 through the first opening of the first buckle surface 11, and the first assembly column 121 is rolled outward under the guidance of the conical surface of the first conical gasket 112 when being extruded, and a first flange is formed in the second cavity.

[0044] When assembling, the first buckle surface 11 is located on one side of the first fabric, and the bow cup 12 is located on the other side of the first fabric. The first assembly column 121 of the bow cup 12 can penetrate through the first fabric and extrude and cooperate with the first conical gasket 112, so that the first assembly column 121 forms a first flange in the second cavity, the first flange is clamped with the first buckle surface gasket 111, and the first buckle surface 11 and the bow cup 12 are fixed on the first fabric.

[0045] The four-way buckle in the prior art sets the assembly column on the buckle surface, sets the conical gasket in the bow cup 12, and rolls the assembly column in and out of the bow cup 12 when assembling, so as to extrude the space in the bow cup 12, which causes the thickness of the four-way buckle to be too large. The four-way buckle is often arranged at the door collar of the clothes, and the relatively thick size of the bottom piece will cause the clothes to be not close-fitting after being buckled, which causes a slight gap at the door collar of the clothes, affects the product quality and use experience, and also affects the overall beauty of the clothes.

[0046] The four-way buckle provided by the utility model is different from the traditional four-way buckle, the first assembly column 121 is installed on the bow cup 12, the first buckle surface 11 and the bow cup 12 are connected in a reverse beating mode, the first buckle surface 11 is provided with a second cavity for forming the first flange of the first assembly column 121, so that the thickness of the bow cup 12 as the bottom piece is reduced, and the problem of the bottom piece being too thick can be effectively avoided.

[0047] In specific embodiments, the slingshot cup 12 has a third cavity in the shape of a ring, the upper part of the third cavity is communicated with the upper environment through the first assembly column 121, and the lower part of the third cavity is communicated with the lower environment through the third opening. A protective pad 123 is arranged in the third cavity, and the protective pad 123 is used to shield the first assembly column 121 from the third opening.

[0048] The protective pad 123 added in the slingshot cup 12 can prevent the first assembly column 121 from being seen from the third opening in the use of the ultra-thin snap fastener, and can provide a more integrated visual experience for the user. In addition, the head of the button bead 22 in the protective button bead 22 will not be scratched in use, and the appearance of the garment and the fastener is improved.
