[0031] The core of the utility model is to disclose a four-joint buckle to have a protective effect.

[0032] 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.

[0033] like Figure 1 As shown, the embodiment of the utility model discloses a female buckle, including a face piece 100 and a slingshot cup 200 .

[0034] The face piece 100 includes a face piece plate 102 and a recorder 101. The recorder 101 is fixed on the face piece plate 102. Specifically, the recorder 101 and the face piece plate 102 can be of an integrated design or a split design, which is not limited here. A first mounting groove matching the recorder 101 is provided on the side of the slingshot cup 200 facing the face piece 100. The slingshot cup 200 includes an annular shell 201. The annular shell 201 is provided on the outside of the slingshot cup 200. The top and bottom of the annular shell 201 are both open designs. The annular shell 201 covers the components provided therein to combine them into one. In order to play a protective role, such as Figure 2 As shown, the extensions of the annular housing 201 at both ends adopt arc transitions. Compared with the right-angle transition in the prior art, the arc transition has a stronger skin-friendly feel, no pressure when touched, and has protective performance. In some embodiments, the material of the annular housing 201 is copper.

[0035] When in use, the face piece 100 and the spring cup 200 are fixed on both sides of a side of a lapel, and the recorder 101 pierces the lapel and enters the first installation groove to complete the installation of the female buckle.

[0036] The female buckle disclosed in the embodiment of the utility model adopts an arc transition method for the extensions of the annular shell 201 to both ends. Whether it is used in the placket, collar or cuffs and other parts that can directly contact the skin, when the female buckle is collided with force in an emergency, the rounded contact surface can well protect the skin, making it less likely to be hurt. It has protective performance and can be applied to children's clothing. The female buckle disclosed in the embodiment of the utility model does not need to increase components and costs, and can be used with a variety of male buckles, and has a wide range of applications.

[0037] like Figure 2-Figure 3 As shown, the female buckle disclosed in the embodiment of the utility model, the elastic cup 200 includes an annular shell 201, an elastic element 202, a base 203, a top plate 204 and a transition piece 205.

[0038] The base 203 is provided with a plug-in slot for plugging with a male buckle. The plug-in slot is provided with an elastic element installation slot, in which the elastic element 202 is provided. The elastic element 202 can be a spring ring, and the material of the spring ring can be copper. The top plate 204 is provided on the base 203. Specifically, the base 203 is provided with an annular groove, and the top plate 204 is provided with an annular protrusion that matches the annular groove.

[0039] A second mounting groove is formed between the top plate 204 and the base 203, and the transition piece 205 is arranged in the second mounting groove. A first mounting groove matching with the recorder 101 is formed between the transition piece 205 and the top plate 204, and a conical protrusion is arranged on the transition piece 205. It should be noted that the recorder 101 is a round tube when not assembled. When the recorder 101 is inserted into the first mounting groove, it will be stretched along the taper of the conical protrusion spike, so that the face piece 100 and the slingshot cup 200 are installed together. The annular shell 201 is coated on the outer periphery of the elastic element 202, the top plate 204 and the base 203. The extension part includes a first extension part extending toward the elastic element 202 and a second extension part extending toward the top plate 204. The top plate 204 is provided with a slot matching with the second extension part. In some embodiments, the material of the top plate 204 and the base 203 is copper, and the material of the transition piece 205 is zinc alloy. The zinc alloy has a relatively low melting point and is easy to cast.

[0040] During assembly, the face piece 100 and the slingshot cup 200 are fixed on both sides of a lapel on one side, and pressure is applied to the face piece plate 102 of the face piece 100 so that the recorder 101 pierces the lapel and enters the first installation groove. The recorder 101 is stretched along the taper of the conical protrusion spikes, so that the face piece 100 and the slingshot cup 200 are installed together.

[0041] On the basis of the above embodiment, the inner and outer rings of the first extension part are both arc-shaped transitions, which can improve the stability of assembly. The end of the first extension part is extended to abut against the elastic element 202. This design can reduce the gap between the annular housing 201 and the elastic element 202. As shown by the number A in the figure, the conventional assembly gap is more than 50 threads. The improved gap-free design can avoid the risk of meat being clamped, and is safer.

[0042] In some embodiments, Figure 3 As shown, the first extension portion includes a first arc angle and a second arc angle, such as Figure 3 As shown in α and β, the first arc angle and the second arc angle are arranged relative to each other, the degree range of the arcs of the first arc angle and the second arc angle are both 20°-30°, and the degrees of the first arc angle and the second arc angle may be equal or unequal.

[0043] The utility model also discloses a snap button, comprising a male button and a female button as in the above embodiment.

[0044] like Figure 1 As shown, the male buckle includes a convex bead 300 and a base nail 400. A second mounting hole matching with the base nail 400 is provided on the side of the male buckle facing the base nail 400. During installation, the base nail 400 is inserted into the convex bead 300 to form the male buckle. The convex bead 300 is provided with a plug-in column matching with the plug-in groove of the elastic cup 200. The convex bead 300 is inserted into the plug-in groove of the female buckle, and the elastic element 202 clamps the plug-in column to complete the assembly.

[0045] Taking the assembly of the snap button on the lapel as an example, the face piece 100 and the spring cup 200 are fixed on both sides of one side of the lapel, and pressure is applied to the face piece plate 102 of the face piece 100, so that the recorder 101 pierces the lapel and enters the first installation groove, and the recorder 101 is stretched along the taper of the conical protrusion spike, so that the face piece 100 and the spring cup 200 are installed together. The convex bead 300 and the bottom nail 400 are fixed on both sides of the lapel on the other side, and then the plug-in column is plugged into the plug-in groove of the spring cup 200, so as to realize the connection of the two sides of the lapel.

[0046] The four-joint buckle disclosed in the embodiment of the utility model has the female buckle disclosed in the above embodiment, so it has a protective function, which makes the skin contact protection stronger.

[0047] It should be noted that 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.
