Problems solved by technology

Since the elastic circlip is only clamped on both sides of the buckle bead, the clamping force is not uniform. Therefore, when it is separated from the buckle bead and pulled apart at different positions, different pulling forces will be required, and the elasticity of the elastic circlip is very large during use. It is easy to weaken and cannot clamp the buckle beads, so it cannot be used normally
In addition, such a complex structure is difficult to realize the automation of production.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Figure 8 It is a schematic diagram of the structure of the four-button buckle with the spring surface of the circular circlip. It can be seen from the figure that there are buckle surfaces 1 such as buckle surfaces that are used to be riveted with the fabric and can be fastened or separated from each other. Figure 9 as shown and snap bead 2 as Figure 10 As shown in the composition, the buckle surface 1 wherein is provided with an opening circular retaining spring 4 with an inner hole smaller than the outer diameter of the head of the buckle bead 2 by the surface member 3 and the orifice. Figure 11 The spring surface 5 shown is as Figure 12 Riveted as shown, the orifice of the spring surface 5 is provided with an annular sinkhole 6, and the opening circular retaining spring 4 with an inner hole smaller than the outer diameter of t...

Abstract

The invention discloses a snap fastener of a spring surface with a round snap spring. The snap fastener of the spring surface with the round snap spring has a simple structure and reliable connection, is easy to achieve production automation and is composed of female fasteners and male fasteners which are respectively riveted with fabric and can be fastened and released with each other, wherein the female fasteners are formed by riveting the fabric with the spring surface with orifices provided with elastic snap springs. The snap fastener of the spring surface with the round snap spring is characterized in that the elastic snap spring is an round opening snap spring with the size of an inner hole smaller than the external diameter of the head of the male fastener; a ring sink pit is arranged on the orifice of the spring surface, the round opening snap spring is arranged in the ring sink pit, the end face of the orifice of the spring surface is fixed with a block piece which can prevent the round opening snap spring from coming off from the sink pit. By almost snapping the male fastener all around, the connection between the female fastener and the male fastener is very reliable. Besides, an elastic round snap spring with the structure has a long service life and is difficult to lead to a fatigue damage, thereby being more applicable to large-scale automatic production.

Description

technical field [0001] The invention relates to a connecting piece on clothing, in particular to a four-button buckle with a circular spring surface. Background technique [0002] The usual four-button button includes a button surface and a button bead that are riveted with the fabric and can be fastened or separated from each other. figure 1 As shown, the buckle surface is as figure 2 Shown is by surface pieces such as image 3 As shown, the elastic clamping springs on both sides of the orifice are clamped as Figure 4 The spring surface shown is Figure 5 , Image 6 , Figure 7 Riveted as shown. Utilize the elasticity of the elastic circlip to clamp the button ball in the hole on the spring surface. Since the elastic circlip is only clamped on both sides of the buckle bead, the clamping force is not uniform. Therefore, when it is separated from the buckle bead and pulled apart at different positions, different pulling forces will be required, and the elasticity of ...
