Quadruple steel buckle facilitating buckling

Abstract

A snap steel buckle facilitating buckling comprises a face buckle, a female buckle, a male buckle and a long nail. The female buckle comprises a female buckle face, a spring containing cavity, a face buckle connecting column and a spring. The face buckle connecting column comprises a connecting column body, a limiting table and a spring receding opening. The spring receding opening is arranged in a crescent shape and comprises an arc-shaped edge located on the face buckle connecting column and a right-angle edge located on the buckle face of the female buckle. When the female buckle inserting column is inserted into the through hole of the face buckle connecting column, the female buckle inserting column firstly abuts against the two clamping legs of the spring, so that the clamping legs slide towards the side away from the buckle face of the female buckle along the arc-shaped edge, and then the female buckle inserting column and the face buckle connecting column are inserted into the through hole of the face buckle connecting column. Due to the fact that the outer contour of the arc-shaped edge is inclined on the connecting column body, sliding of the clamping leg becomes easy, the spring or the female buckle inserting column is not prone to being damaged, and the service life of the whole snap steel buckle can be prolonged.

Description

Technical Field

[0001] The utility model relates to the field of snap buckles, in particular to a snap buckle that is easy to buckle. Background Art

[0002] Snap buttons are a common clothing accessory, typically used to secure collars, cuffs, pockets, and other areas of clothing. They consist of four cooperating components: a face button, a female button, a sub-button, and a spike. Their simple and practical design provides excellent fastening and decorative appeal, making them widely used in clothing production and everyday wear.

[0003] In the prior art, the spring sliding opening of a snap buckle is typically square, and the spring can only move vertically up and down. Therefore, the snap buckle's fastening process relies entirely on the spring expanding and releasing the spring when the sub-buckle is pressed down, allowing it to insert into the mother buckle. The fastening force is also entirely provided by the spring's contraction force. Consequently, during use, a significant amount of pressure is often required to secure the sub-buckle to the mother buckle, and each use causes some damage to the spring. Prolonged use can easily damage the spring, shortening its service life. Furthermore, the spring's inherent tension is limited, resulting in weak fastening security and a tendency to break under stress. Summary of the Invention

[0004] In view of this, the utility model provides a four-in-one steel buckle that is easy to buckle in and has a firm buckle, so as to solve the above problems.

[0005] A four-piece steel buckle that facilitates fastening includes a face buckle, a female buckle fixedly connected to the face buckle, a male buckle configured to mate with the female buckle, and a spike for securing the male buckle. The female buckle includes a female buckle face, a spring-receiving cavity disposed on one side of the female buckle face, a face buckle connecting post disposed on one side of the female buckle face, and a spring housed in the spring-receiving cavity. The face buckle connecting post includes a connecting post body, a stopper disposed at one end of the connecting post body, and two spring clearance openings symmetrically disposed on the side walls of the connecting post body. The spring clearance openings are crescent-shaped and include an arcuate edge on the face buckle connecting post and a right-angled edge on the female buckle face. Two engaging legs of the spring are inserted into the spring clearance openings. When the female buckle inserting post is inserted into the through hole of the face buckle connecting post, it first abuts against the two engaging legs of the spring, causing the engaging legs to slide along the arcuate edge toward the side away from the female buckle face.

[0006] Furthermore, the connecting column body is centrally arranged on the buckle surface of the female buckle, and the connecting column body is a cylindrical structure.

[0007] Furthermore, the spring accommodating cavity is arranged on the side of the female buckle surface facing the face buckle.

[0008] Furthermore, the limiting platform is arranged at one end of the connecting column body facing away from the female buckle surface, and the limiting platform is arranged in a circular ring shape.

[0009] Furthermore, the face buckle includes a face buckle body and a female buckle connecting shaft fixedly connected to the face buckle body, and the inner contour diameter of the limit platform is larger than the diameter of the female buckle connecting shaft.

[0010] Furthermore, the spring is a W-shaped spring symmetrically arranged on both sides of the connecting column body.

[0011] Furthermore, the male buckle includes a male buckle buckle surface, and a female buckle plug-in column arranged on one side of the male buckle buckle surface, and the plug-in column includes a plug-in column body, and a plug-in limit portion fixedly arranged at one end of the plug-in column body.

[0012] Furthermore, one end of the plug-in column body is fixedly connected to the male buckle surface, and the other end is fixedly connected to the plug-in limiting portion, and the diameter of the plug-in limiting portion is larger than the diameter of the plug-in column body.

[0013] Compared with the prior art, the four-in-one steel buckle provided by the present invention is convenient for buckling in, and a spring clearance opening is provided on the face buckle connecting column. The spring clearance opening is crescent-shaped and includes an arcuate edge located on the face buckle connecting column, and a right-angled edge located on the buckle surface of the female buckle. The two clamping legs of the spring are inserted into the spring clearance opening. When the female buckle plug-in column is inserted into the through hole of the face buckle connecting column, it will first press against the two clamping legs of the spring, causing the clamping legs to slide along the arcuate edge away from the buckle surface of the female buckle. Due to the existence of the arcuate edge, in the process of the clamping legs sliding along the arcuate edge away from the buckle surface of the female buckle, the distance between the two clamping legs becomes larger, so that the female buckle plug-in column can be inserted into the through hole of the face buckle connecting column, thereby achieving the purpose of buckling the male buckle and the female buckle. Moreover, since the outer contour of the arc-shaped edge is inclined on the connecting column body, the sliding of the clamping leg becomes easy and it is not easy to damage the spring or the female buckle plug-in column, thereby improving the service life of the entire four-in-one steel buckle.

[0017] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the present invention herein is not intended to limit the scope of protection of the present invention.

[0018] like Figures 1 to 3 , which is a schematic structural diagram of a four-piece steel buckle for facilitating fastening provided by the present invention. The four-piece steel buckle for facilitating fastening includes a face buckle 10, a female buckle 20 fixedly connected to the face buckle 10, a male buckle 30 configured to mate with the female buckle 10, and a spike 40 for securing the male buckle 30. It is conceivable that the four-piece steel buckle for facilitating fastening may also include other functional components, such as assembly structures and decorative components, all of which are well known to those skilled in the art and will not be further elaborated here.

[0019] The face buckle 10 is the visible portion of the buckle-fastening, four-piece steel buckle during use. It secures the female buckle 20 and provides a decorative effect. The face buckle 10 comprises a face buckle body 11 and a female buckle connecting shaft 12 fixedly connected to the face buckle body 11. The face buckle body 11 is typically circular, but can be designed with other shapes, such as polygonal, depending on aesthetic requirements. Preferably, a decorative pattern or design can be provided on the side of the face buckle body 11 opposite the female buckle connecting shaft 12, so that the buckle-fastening, four-piece steel buckle not only functions as a fastener but also offers a decorative effect. The female buckle connecting shaft 12 is a hollow tube. The female buckle connecting shaft 12 connects to the female buckle 20 when the four-piece steel buckle is assembled onto a garment, and will be described in further detail below in conjunction with the female buckle 20. The face buckle 10 itself is well known to those skilled in the art and will not be described in detail here.

[0020] The female buckle 20 includes a female buckle surface 21, a spring accommodating cavity 22 arranged on one side of the female buckle surface 21, a face buckle connecting column 23 arranged on one side of the female buckle surface 21, and a spring 24 accommodated in the spring accommodating cavity 22.

[0021] The female buckle surface 21 is circular. When the face buckle 10 and the female buckle 20 are installed together, the female buckle surface 21 and the face buckle body 11 clamp the installation fabric between the female buckle surface 21 and the face buckle body 11.

[0022] The spring accommodating cavity 22 is provided on the side of the female buckle surface 21 facing the face buckle 10 , and is used to accommodate the spring 24 .

[0023] The face buckle connecting column 23 includes a connecting column body 231 , a limiting platform 232 arranged at one end of the connecting column body 231 , and two spring clearance openings 233 symmetrically arranged on the side walls of the connecting column body 231 .

[0024] The connecting post body 231 is centrally located on the female buckle surface 21 and has a cylindrical structure. One end of the connecting post body 231 is fixedly connected to the female buckle surface 21. The connecting post body 231 is also hollow and tubular, facilitating a plug-and-match connection with the male buckle 30.

[0025] The stopper 232 is disposed on the end of the connecting post body 231 facing away from the female buckle surface 21. The stopper 232 is annular in shape, its outer contour matching that of the connecting post body 231 and securely attached thereto. The inner diameter of the stopper 232 is larger than the diameter of the female buckle connecting shaft 12, facilitating insertion of the female buckle connecting shaft 12. To install the face buckle 10 and the female buckle 20, a small hole is first created at the corresponding location on the garment where the snap fastener is to be installed. The female buckle connecting shaft 12 is then inserted through the hole and into the through-hole of the face buckle connecting post 23 from one end of the stopper 232. A specific tool is then used to insert the female buckle connecting shaft 12 into one side of the face buckle connecting post 23 and stretch it open, so that the diameter of one end of the female buckle connecting shaft 12 is larger than the inner diameter of the stopper 232, thereby securing the face buckle 10 and the female buckle 20. The connection structure between the face buckle 10 and the female buckle 20 and the installation tool itself are prior art and will not be described in detail here.

[0026] The spring clearance opening 233 is used to set the spring 24 so that the spring 24 is stretched along the spring clearance opening 233 when subjected to the squeezing force from the male buckle 30, thereby facilitating the insertion and removal of the male buckle 30 from the face buckle connecting column 23. Two spring clearance openings 233 are symmetrically arranged at one end of the connecting column body 231 close to the female buckle buckle surface 21. Figure 3As shown, the spring clearance opening 233 is crescent-shaped, with one side of the crescent facing the side of the female buckle surface 21, so that the outer contour of the spring clearance opening 233 is inclined on the connecting column body 231, which facilitates the sliding of the spring 24 under force, prevents the spring 14 from being damaged due to excessive force during the sliding process, and prolongs the service life of the spring 24. Specifically, in a cross section along the central axis of the face buckle connecting column 23, the spring clearance opening 233 includes an arcuate edge 234 located on the face buckle connecting column 23 and a right-angled edge 235 located on the female buckle surface 21. During manufacturing, the arcuate edge 234 can be formed by punching with an arc shovel in a direction perpendicular to the central axis of the buckle surface connecting column 23. When the two engaging legs of the spring 24 are inserted into the spring clearance opening 233, and when the female buckle plug-in column 32 of the male buckle 30 is inserted into the through-hole of the face buckle connecting column 23, it will first press against the two engaging legs of the spring 24, causing the engaging legs to slide along the arcuate edge 234 away from the female buckle buckle surface 21. Due to the presence of the arcuate edge 234, the sliding of the engaging legs becomes easier and is less likely to damage the spring 24 or the female buckle plug-in column 32, thereby improving the life of the entire four-in-one steel buckle. In addition, due to the presence of the arcuate edge 234, the distance between the two engaging legs increases as the engaging legs slide along the arcuate edge 234 away from the female buckle buckle surface 21, thereby allowing the female buckle plug-in column 32 to be inserted into the through-hole of the face buckle connecting column 23, thereby achieving the purpose of fastening the male buckle 30 with the female buckle 20.

[0027] The spring 24 is a W-shaped spring symmetrically positioned on either side of the connecting column body 231. It has two engaging legs, as described above, that are inserted into the spring clearance openings 233. The spring 24 provides a clamping force for the four-piece steel buckle, facilitating the engagement and disengagement of the female buckle 20 and the male buckle 30. The spring 24 can be made of a metal material with excellent elasticity and durability, such as stainless steel or carbon steel. The spring 24 is constructed from a single, unbroken wire with its ends bent into a W-shape and its center curved to conform to the sidewalls of the spring accommodating cavity 22. When installed in the spring accommodating cavity 22, the two ends of the W-shaped spring 24 are respectively secured within the two spring clearance openings 233, with the center of the arc abutting the inner wall of the spring accommodating cavity 22. The free ends on either side abut against the female buckle buckle surface 21, securing the spring 24. The spring 24 is well known to those skilled in the art and will not be further described here.

[0028] The male buckle 30 includes a male buckle surface 31 and a female buckle plug-in post 32 disposed on one side of the male buckle surface 31. The buckle surface 31 is used to mount the female buckle plug-in post 32 and facilitates the installation of the male buckle 30 on clothing in conjunction with the long nail 40. The plug-in post 32 includes a plug-in post body 321 fixedly connected to the male buckle surface 31 and a plug-in limiter 322 fixedly disposed on one end of the plug-in post body 321. The plug-in limiter 322 has a diameter greater than that of the plug-in post body 321. When the male buckle 30 is engaged with the female buckle 20, one end of the insertion limiter 322 abuts against the spring 24, and the engaging leg of the spring 24 slides along the arcuate edge 234 of the spring clearance opening 233 toward the side away from the female buckle buckle surface 21, increasing the distance between the two engaging legs, thereby allowing the female buckle plug post 32 to be inserted into the through-hole of the face buckle connecting post 23. When the distance between the two engaging legs of the spring 24 is greater than the limiting portion 322, the two engaging legs decrease in distance and slide along the limiting portion 322 onto the plug post body 321. Under the clamping force of the spring 24, the plug post 32 is secured in the through-hole of the face buckle connecting post 23. The male buckle 30 itself is well known to those skilled in the art and will not be described in detail here.

[0029] The long spike 40 is arranged in pairs with the male buckle 30, and the long spike 40 is used to install the male buckle 30 in places where a snap button is required, such as clothing and bags. The long spike 40 itself is a prior art and will not be described in detail here.

[0030] In summary, the face buckle 10 and the female buckle 20 of the four-in-one steel buckle are paired, the male buckle 30 and the long spike 40 are paired, and the female buckle 20 and the male buckle 30 are matched. During installation, the face buckle 10 and the female buckle 20, as well as the male buckle 20 and the long spike 40, are installed in pairs on both sides of the material to be fastened. Then, the female buckle plug-in column 32 is aligned with the center of the female buckle 20. The face buckle 10 is pressed downward, causing the female buckle plug-in column 32 to push the spring 24 down along the spring clearance opening 233, so that the female buckle plug-in column 32 is inserted into the female buckle 20, and the spring 24 is reset. Under the clamping force of the spring 24, the female buckle plug-in column 32 and the female buckle 20 are snapped together to form a buckle.

[0031] Compared to the prior art, the four-piece steel buckle provided by the present invention facilitates snap-on insertion by defining a spring clearance opening 233 on the face buckle connecting post 23. This spring clearance opening 233 is crescent-shaped and includes an arcuate edge 234 located on the face buckle connecting post 23 and a right-angled edge 235 located on the female buckle surface 21. The two engaging legs of the spring 24 are inserted into this spring clearance opening 233. When the female buckle inserting post 32 is inserted into the through-hole of the face buckle connecting post 23, it first abuts against the two engaging legs of the spring 24, causing them to slide along the arcuate edge 234 away from the female buckle surface 21. Due to the presence of the arcuate edge 234, as the locking legs slide along the arcuate edge 234 away from the female buckle surface 21, the distance between the two locking legs increases, thereby allowing the female buckle plug post 32 to be inserted into the through hole of the face buckle connecting post 23, achieving the purpose of fastening the male buckle 30 to the female buckle 20. In addition, because the outer contour of the arcuate edge 234 is inclined on the connecting post body 231, the sliding of the locking legs becomes easier and is less likely to damage the spring 24 or the female buckle plug post 32, thereby increasing the service life of the entire four-in-one steel buckle.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
