Description

Technical Field

[0001] This invention relates to the field of snap fastener technology, and in particular to a rotating fastening structure, a snap fastener, and an assembly method and tool for assembling the rotating fastening structure. Background Technology

[0002] Snap fasteners, also known as four-in-one fasteners, concealed snaps, or mother-and-child snaps, refer to a type of button that combines components with a four-in-one fastener. Component A of the snap fastener is called the female snap, which can be engraved with patterns on its wide edge, has a hole in the middle, and two parallel springs on its side. Component B of the snap fastener is called the male snap, which has a flange in the middle. By pressing the flange into the hole of the female snap, it is clamped by the spring, generating an opening and closing force to secure clothing.

[0003] However, traditional snaps are mainly installed on substrates such as fabric, bags, or leather by riveting. They are usually suitable for deformable materials such as metal or plastic. When snaps are made of materials that cannot be deformed or have poor yield strength, they are difficult to fix and install on substrates such as fabric or leather. Snaps are highly dependent on materials, which limits the range of materials that can be selected for snaps and is not conducive to improving the market competitiveness of snap products. Summary of the Invention

[0004] Therefore, it is necessary to provide a rotating fastening structure, a method for assembling the fastener and the rotating fastening structure, and an assembly tool to address the technical problem of limited material selection for snap fasteners.

[0005] A rotating fastening structure includes a face piece and a rotating base piece that fastens with the face piece. The face piece includes a face piece body, a non-cylindrical boss, and a T-shaped limiting member. The non-cylindrical boss is connected to the face piece body and is used to provide a gripping part for external installation tools. The vertical part of the T-shaped limiting member is connected to the side of the non-cylindrical boss facing away from the face piece body, and a slot is respectively formed at both ends of the horizontal part of the T-shaped limiting member.

[0006] The rotating base includes a base body, on which a mounting hole is provided. Two limiting steps are symmetrically arranged on the inner surface of the mounting hole. Each limiting step is provided with a protrusion that mates with the slot. A through channel is provided between the two limiting steps.

[0007] When the horizontal part of the T-shaped limiting member passes through the mounting hole in the vertical part, it passes through the through-channel. The bottom body is used to drive the protrusion to rotate relative to the horizontal part of the T-shaped limiting member under the action of external torsional force, and to embed the protrusion into the slot.

[0008] In one embodiment, the surface body has a plurality of tapered pins on the side facing the T-shaped limiting member, and the bottom body has a plurality of tapered holes on the side facing the surface body that cooperate with the tapered pins. Each tapered pin is inserted into a corresponding tapered hole and abuts against the inner surface of the tapered hole.

[0009] In one embodiment, the two ends of the horizontal portion have arcuate portions that mate with the inner surface of the mounting hole.

[0010] In one embodiment, a positioning element is provided on the outer side of the base body, and the positioning element is a lug or a recess.

[0011] In one embodiment, the limiting ladder has limiting portions formed on both sides of the protrusion, and the two limiting portions abut against the two opposite sides of the horizontal portion to jointly define the position of the horizontal portion.

[0012] The present invention also provides a snap fastener including the above-described rotating fastening structure, further comprising a male snap fastener with a flange formed on its outer surface and a female snap fastener with a recess formed on its inner surface. The male snap fastener is mounted on the side of the bottom body of one of the rotating fastening structures facing away from the top body, and the female snap fastener is mounted on the side of the bottom body of another rotating fastening structure facing away from the top body and fastens with the male snap fastener.

[0013] The present invention also provides an assembly method for a rotating fastening structure, used to clamp the fastened object between the face piece and the rotating base piece, wherein the fastened object has a positioning hole, and includes the following steps:

[0014] Step S1: A rotating fastening structure is proposed, the rotating fastening structure including a face piece and a rotating bottom piece that fastens with the face piece, characterized in that the face piece includes a face piece body, a non-cylindrical boss and a T-shaped limiting member, the non-cylindrical boss is connected to the face piece body and is used to provide a gripping part for external installation tools; the vertical part of the T-shaped limiting member is connected to the side of the non-cylindrical boss facing away from the face piece body, and a slot is respectively opened at both ends of the horizontal part of the T-shaped limiting member;

[0015] The rotating base includes a base body, on which a mounting hole is provided. Two limiting steps are symmetrically arranged on the inner surface of the mounting hole. Each limiting step is provided with a protrusion that mates with the slot. A through channel is provided between the two limiting steps.

[0016] Step S2: Pass the T-shaped limiting member sequentially through the positioning hole of the fastened object and the mounting hole of the bottom body, and make the horizontal part pass through the through-hole;

[0017] Step S3: Rotate the bottom body to make the bottom body drive the protrusion to rotate relative to the horizontal part of the T-shaped limiting member, and insert the protrusion into the slot to connect the T-shaped limiting member and the rotating bottom body.

[0018] The present invention also provides an assembly tool for the above-mentioned rotating fastening structure, comprising a lower mold and an upper mold.

[0019] The lower mold includes a base and a limiting sheet. The base is installed on the worktable of an external riveting machine. The top surface of the base has a groove for receiving the face piece, and the bottom surface of the groove is used to receive the side of the face piece body facing away from the T-shaped limiting piece. The limiting sheet is slidably connected to the top surface of the base and has a limiting notch corresponding to the groove. The inner surface of the limiting notch is used to cooperate with the outer surface of the non-cylindrical boss of the face piece and limit the displacement of the face piece in the horizontal direction. The edge of the limiting notch is used to press against the face piece body and limit the displacement of the face piece in the vertical direction.

[0020] The upper mold includes a rotating component and a fixed tube. The rotating component is connected to the output end of the drive component of an external riveting machine and is used to grip the rotating bottom component and drive it to rotate relative to the surface component under the drive of the external riveting machine, so as to fasten the surface component and the rotating bottom component. The fixed tube is sleeved on the rotating component and fixedly installed on the external riveting machine. A spiral rotating track is opened on the tube wall of the fixed tube. A limit post is installed on the outer side of the rotating component. The limit post passes through the rotating track and is used to limit the movement trajectory of the rotating component.

[0021] In one embodiment, a pull rod is provided at one end of the limiting sheet away from the limiting notch.

[0022] In one embodiment, the end of the rotating member is provided with a clamping part for gripping the rotating base, the inner contour of the clamping part cooperating with the outer contour of the rotating base.

[0023] The rotating fastening structure of this invention involves passing a T-shaped limiting member of the face piece through a connecting channel, followed by rotating the main body of the base piece. This causes the protrusions on the limiting ladder of the rotating base piece to embed into the slots at both ends of the horizontal portion of the T-shaped limiting member. Thus, the protrusions are constrained by the inner surface of the slots and connected to the T-shaped limiting member, achieving a secure connection between the face piece and the rotating base piece. This allows for connection of the face piece and the rotating base piece on the substrate without deforming the rotating fastening structure when there are openings in the fabric or leather, expanding the material selection range for the rotating fastening structure. This invention also provides a snap fastener including the above-described rotating fastening structure, an assembly method based on the rotating fastening structure, and a tool suitable for assembling the rotating fastening structure, which helps improve the fastening processing efficiency of the rotating fastening structure and thus enhances its market competitiveness.

[0038] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Please refer to the following: Figures 1 to 4 The present invention provides a rotating fastening structure 10, which includes a face piece 110 and a rotating bottom piece 120 that fastens with the face piece 110. The face piece 110 includes a face piece body 111, a non-cylindrical boss 112 and a T-shaped limiting member 113. The non-cylindrical boss 112 is connected to the face piece body 111 and is used to provide a gripping part for external installation tools. The vertical part 113a of the T-shaped limiting member 113 is connected to the side of the non-cylindrical boss 112 that faces away from the face piece body 111, and a slot 113c is respectively opened at both ends of the horizontal part 113b of the T-shaped limiting member 113. The rotating base 120 includes a base body 121, on which a mounting hole 121a is provided. Two limiting steps 122 are symmetrically arranged on the inner surface of the mounting hole 121a. Each limiting step 122 is provided with a corresponding protrusion 123 that mates with the slot 113c. A through channel 124 is provided between the two limiting steps 122. When the horizontal part 113b of the T-shaped limiting member 113 passes through the mounting hole 121a in the vertical part 113a, it passes through the through channel 124. The base body 121 is used to drive the protrusion 123 to rotate relative to the horizontal part 113b of the T-shaped limiting member 113 under the action of external torsional force, and to embed the protrusion 123 into the slot 113c.

[0040] The rotating fastening structure 10 of the present invention is implemented by passing the T-shaped limiting member 113 of the face piece 110 through the through-passing channel 124, and then rotating the bottom body 121 so that the protrusion 123 on the limiting platform 122 of the rotating bottom piece 120 is embedded in the slots 113c at both ends of the horizontal part 113b of the T-shaped limiting member 113. In this way, the protrusion 123 will be connected to the T-shaped limiting member 113 under the constraint of the inner surface of the slot 113c, that is, a firm connection between the face piece 110 and the rotating bottom piece 120 is achieved. In this way, when there are holes in the fabric or leather, the connection between the face piece 110 and the rotating bottom piece 120 on the substrate can be achieved without deforming the rotating fastening structure 10, which expands the material selection range of the rotating fastening structure 10 and thus enhances the market competitiveness of the rotating fastening structure 10.

[0041] It should be noted that the face piece 110 and the rotating base piece 120 of the present invention can be any commercially available material used to produce snaps, such as deformable materials like metal and plastic, or materials with poor plasticity such as wood, ceramics, and glass, which will not be elaborated here.

[0042] The face piece 110 is used to cooperate with the rotating base piece 120 to realize the installation of the rotating fastening structure 10 on the fabric or leather substrate. Specifically, the face piece body 111 is used to abut against the edge of the positioning hole when the T-shaped limiting member 113 passes through the positioning hole of the fastened object, in other words, to fit against the surface of the fastened object to realize the connection between the face piece 110 and the fastened object. In one embodiment, a plurality of conical pins 111a are provided on the side of the face piece body 111 facing the T-shaped limiting member 113, and a plurality of conical holes 121b are provided on the side of the base piece body 121 facing the face piece body 111 to cooperate with the conical pins 111a. Each conical pin 111a is inserted into a corresponding conical hole 121b and abuts against the inner surface of the conical hole 121b. Thus, while the T-shaped limiting member 113 and the limiting ladder 122 are connected, the face piece 110 and the rotating base piece 120 can also be connected by the conical nail 111a and the conical hole 121b, further improving the stability of the connection between the face piece 110 and the rotating base piece 120. In addition, by setting the conical nail 111a on the face piece body 111 and opening the conical hole 121b on the base piece body 121, when the rotating fastening structure 10 is installed on the fabric or leather substrate, the conical nail 111a presses the substrate material and pushes it into the conical hole 121b, increasing the contact area between the rotating fastening structure 10 and the substrate, and helping to improve the stability of the rotating fastening structure 10 on the substrate.

[0043] The non-cylindrical boss 112 provides a gripping area for external installation tools during the assembly of the rotating fastening structure 10, thereby positioning the surface part 110 as a whole and preventing it from shaking or moving during assembly, thus facilitating the effective assembly of the rotating fastening structure 10. In one embodiment, the cross-section of the non-cylindrical boss 112 can be square, hexagonal, octagonal, or any other non-cylindrical boss 112 with two relatively parallel sides, so that the external installation tool can clamp the non-cylindrical boss 112 and assemble the surface part 110 and the rotating base 120.

[0044] The T-shaped limiting member 113 is used to cooperate with the limiting step 122 on the rotating base 120. Specifically, the slot 113c on the horizontal portion 113b of the T-shaped limiting member 113 engages with the protrusion 123 on the limiting step 122. In this way, the rotating base 120 is difficult to rotate relative to the surface member 110 or move in a direction away from the surface member body 111 under the cooperation of the protrusion 123 and the slot 113c, thereby achieving the limiting of the rotating base 120 and improving the stability of the connection between the surface member 110 and the rotating base 120. In one embodiment, the two ends of the horizontal portion 113b respectively have arc portions 113d that cooperate with the inner surface of the mounting hole 121a. In other words, the shapes of the two end faces of the horizontal portion 113b are consistent with the shape of the inner surface shared by the mounting hole 121a and the through channel 124. While facilitating the passage of the horizontal portion 113b of the T-shaped limiting member 113 through the through channel 124, the inner surface of the through channel 124 limits the side of the horizontal portion 113b of the T-shaped limiting member 113. In this way, the passage path of the T-shaped limiting member 113 is further limited, preventing the T-shaped limiting member 113 from shaking relative to the rotating base member 120, thereby improving the assembly efficiency of the surface member 110 and the rotating base member 120. Furthermore, each slot 113c corresponds to one end face of the through-section 113b. Thus, even when the width of the vertical portion 113a of the T-shaped limiting member 113 is less than the width of the through-channel 124, when the two opposite inner sides of the slot 113c surround the two opposite outer sides of the protrusion 123, the protrusion 123 can be embedded in the slot 113c without adjusting the T-shaped limiting member 113 in the width direction of the through-channel 124. This helps to reduce the difficulty of the matching operation between the protrusion 123 and the slot 113c, thereby improving the fastening efficiency.

[0045] The rotating base 120 is used to engage with one end of the T-shaped limiting member 113 that protrudes from the positioning hole of the fastened object, and together with the face member 110, presses the fastened object together to realize the installation of the rotating fastening structure 10 on the fastened object. Among them, the base body 121 is used to abut against the side of the fastened object facing away from the face body 111, and the limiting ladder 122 is used to cooperate with the horizontal part 113b of the T-shaped limiting member 113 and limit the displacement of the horizontal part 113b of the T-shaped limiting member 113 along the axial direction of the vertical part 113a, preventing the horizontal part 113b of the T-shaped limiting member 113 from sliding out of the mounting hole 121a. Furthermore, by providing a protrusion 123 on the limiting ladder 122, the movement of the horizontal portion 113b of the T-shaped limiting member 113 within the plane of the limiting surface of the limiting ladder 122 is limited. This prevents the T-shaped limiting member 113 from rotating under external force or the rotating base member 120 from rotating relative to the T-shaped limiting member 113 under external force, thus preventing the horizontal portion 113b from sliding out of the through channel 124. This improves the reliability of the connection between the surface member 110 and the rotating base member 120.

[0046] In one embodiment, a positioning element 121c is provided on the outer side of the base body 121. The positioning element 121c is a lug or a recess. By providing the positioning element 121c on the outer side of the base body 121, it is convenient for the external clamp to hold the base body 121 during the assembly of the rotating fastening structure 10, so as to facilitate the fastening operation between the face piece 110 and the rotating base piece 120.

[0047] In one embodiment, limiting portions 125 are formed on both sides of the protrusion 123 on the limiting step 122. The two limiting portions 125 abut against the two opposite sides of the horizontal portion 113b, respectively, to jointly limit the position of the horizontal portion 113b. By forming limiting portions 125 on both sides of the protrusion 123 on the limiting step 122, the position of the horizontal portion 113b of the T-shaped limiting member 113 is further limited. In addition, the limiting part 125 can also be used to guide the horizontal part 113b of the T-shaped limiting member 113 during the rotation of the rotating base 120. Specifically, the rotating base 120 rotates relative to the horizontal part 113b of the T-shaped limiting member 113 when the top surface of the limiting part 125 is lower than the bottom surface of the horizontal part 113b of the T-shaped limiting member 113. The top surface of the limiting part 125 being lower than the bottom surface of the horizontal part 113b of the T-shaped limiting member 113 means that there is a gap between the limiting part 125 and the bottom surface of the horizontal part 113b in the length direction of the vertical part 113a. In this case, the bottom surface of the horizontal part 113b can be made to fit against the top surface of the limiting part 125, and the bottom body 121 can be gradually rotated until the protrusion 123 is embedded in the slot 113c of the horizontal part 113b. This avoids blindly rotating the bottom body 121, which helps to improve the accuracy of the engagement between the protrusion 123 and the slot 113c, thereby improving the fastening efficiency between the surface part 110 and the rotating bottom part 120.

[0048] It should be noted that the rotating fastening structure 10 in this embodiment can be used as a rivet, i.e., a stud. In actual production, the area of ​​the main body 111 can be increased, for example, by making the main body 111 a sheet-like sign structure, and by setting multiple T-shaped limiting members 113 on a single main body 111, with a rotating bottom member 120 correspondingly fitted and connected to each T-shaped limiting member 113. Figure 5 As shown, when a single faceplate body 111 is provided with multiple mating bodies consisting of T-shaped limiting members 113 and rotating base members 120, the rotating fastening structure 10 can be used as a label installed on fabric or leather. Furthermore, other components can be added to the rotating fastening structure 10 to expand its function and application range.

[0049] Please refer to the following: Figures 6 to 8 The present invention also provides a snap fastener 20 including the above-mentioned rotating fastening structure 10, and further includes a male snap fastener 210 with a flange formed on its outer surface and a female snap fastener 220 with a recess formed on its inner surface. The male snap fastener 210 is installed on the side of the bottom body 121 of the rotating fastening structure 10 facing away from the face body 111 to form a first snap body. The female snap fastener 220 is installed on the side of the bottom body 121 of the other rotating fastening structure 10 facing away from the face body 111 to form a second snap body. The female snap fastener 220 of the second snap body is used to fasten with the male snap fastener 210 of the first snap body.

[0050] The aforementioned snap fastener 20 connects the two substrates by respectively mounting the first and second snap fasteners with the rotating fastening structure 10 onto two pieces of fabric or leather substrate, and fastening the male snap fastener 210 of the first snap fastener with the female snap fastener 220 of the second snap fastener. Since the material of the rotating fastening structure 10 can be a malleable material such as metal or plastic, or a material with poor plasticity such as wood, ceramic, or glass, similarly, the male snap fastener 210 and the female snap fastener 220 can also be made of malleable materials such as metal or plastic, or materials with poor plasticity such as wood, ceramic, or glass. This helps to expand the range of materials for the snap fastener 20, improve the practicality of the product, and promote the diversified development of the product.

[0051] The present invention also provides an assembly method for the aforementioned rotating fastening structure 10, used to clamp the fastened object between the face piece 110 and the rotating base piece 120, wherein the fastened object has a positioning hole, and includes the following steps:

[0052] The T-shaped limiting member 113 is sequentially inserted into the positioning hole of the fastened object and the mounting hole 121a of the bottom body 121, and the horizontal part 113b is inserted into the through-connection channel 124.

[0053] Rotate the base body 121, causing the base body 121 to drive the protrusion 123 to rotate relative to the horizontal portion 113b of the T-shaped limiting member 113, and insert the protrusion 123 into the slot 113c to connect the T-shaped limiting member 113 and the rotating base body 120. Figure 1 , Figure 2 and Figure 3 As shown, in this state, the bottom body 121 is difficult to detach from the T-shaped limiting member 113 due to the cooperation of the protrusion 123 and the slot 113c of the horizontal part 113b, thereby realizing the connection between the surface part 110 and the rotating bottom part 120.

[0054] Please refer to the following: Figures 9 to 14 The present invention also provides an assembly tool 30 for the aforementioned rotating fastening structure 10, the assembly tool 30 including a lower mold 310 and an upper mold 320. The lower mold 310 provides a platform for the assembly operation of the rotating fastening structure 10 and defines the position of the face piece 110. The lower mold 310 includes a base 311 and a limiting sheet 312. The base 311 is mounted on the workbench of an external riveting machine. The top surface of the base 311 has a groove 311a for receiving the face piece 110, and the bottom surface of the groove 311a is used to receive the side of the face piece body 111 facing away from the T-shaped limiting member 113. That is, when the face piece 110 is placed in the groove 311a, the horizontal portion 113b of the T-shaped limiting member 113 is away from the bottom surface of the groove 311a, so that the horizontal portion 113b passes through the through-passing channel 124 of the rotating base piece 120 and cooperates with the protrusion 123 on the limiting ladder 122. The limiting sheet 312 is slidably connected to the top surface of the base 311 and has a limiting notch 312a corresponding to the groove 311a. Preferably, the base 311 has a sliding groove, and the bottom of the limiting sheet 312 is provided with a sliding rail. The sliding rail is engaged with the sliding groove and slidably connected to the inner surface of the sliding groove, so that the limiting sheet 312 can slide relative to the base 311 under force. The inner surface of the limiting notch 312a is used to cooperate with the outer surface of the non-cylindrical boss 112 of the face piece 110 and limit the horizontal displacement of the face piece 110. That is, the inner surface of the limiting notch 312a can abut against and clamp the non-cylindrical boss 112, preventing the face piece 110 from shaking relative to the rotating base piece 120 during the assembly of the rotating fastening structure 10, thereby improving the reliability of the assembly operation. The edge of the limiting notch 312a is used to press against the main body 111 of the surface piece and limit the displacement of the surface piece 110 in the vertical direction. In other words, it prevents the surface piece 110 from leaving the groove 311a under the action of the rotating base piece 120, so as to facilitate the centralized collection of the assembled finished products.

[0055] In one embodiment, a pull rod 312b is provided at one end of the limiting sheet 312 away from the limiting notch 312a. Specifically, during the assembly process of the rotating fastening structure 10, the face piece 110 is first placed in the groove 311a, and then the pull rod 312b is pushed, causing the pull rod 312b to slide on the base 311 toward the face piece 110 and lock the non-cylindrical boss 112 of the face piece 110, so as to facilitate the assembly of the rotating fastening structure 10; after the rotating fastening structure 10 is assembled, the pull rod 312b is pulled, causing the limiting sheet 312 to leave the face piece 110, and the constraint of the limiting sheet 312 on the face piece 110 is released, so as to facilitate the removal of the finished rotating fastening structure 10 from the groove 311a.

[0056] The upper mold 320 is used to drive the rotating base 120 closer to the surface piece 110 and rotate the rotating base 120, so as to install the rotating base 120 on the surface piece 110. The upper mold 320 includes a rotating member 321 and a fixing tube 322. The rotating member 321 is connected to the output end of the drive component of an external riveting machine, and is used to grip the rotating base 120 and drive it to rotate relative to the surface piece 110 under the drive of the external riveting machine, so as to fasten the surface piece 110 and the rotating base 120. In one embodiment, the end of the rotating member 321 is provided with a clamping part 321a for gripping the rotating base 120. The inner contour of the clamping part 321a matches the outer contour of the rotating base 120, so as to clamp the rotating base 120 and control the movement of the rotating base 120.

[0057] The fixed tube 322 is sleeved on the rotating part 321 and fixedly installed on the external riveting machine. A spiral rotating track 322a is opened on the tube wall of the fixed tube 322. A limit post 323 is installed on the outer side of the rotating part 321. The limit post 323 passes through the rotating track 322a and is used to limit the movement trajectory of the rotating part 321. Specifically, after the rotating component 321 clamps the rotating bottom component 120, it moves linearly and approaches the surface component 110 under the drive of the external riveting machine. When the horizontal part 113b of the T-shaped limiting component 113 of the surface component 110 passes through the through-channel 124 of the rotating bottom component 120, and the distance between the bottom surface of the horizontal part 113b of the T-shaped limiting component 113 and the limiting ladder 122 is greater than the height of the protrusion 123, the external riveting machine drives the rotating component 321 and the rotating bottom component 120 to rotate and move linearly in a direction away from the surface component 110. In other words, the rotating bottom component 120 performs a combined rotation and linear motion, i.e., a spiral motion, under the action of the rotating component 321, so that the protrusion 123 gradually aligns with the slot 113c and is embedded in the slot 113c, thereby realizing the connection between the rotating bottom component 120 and the surface component 110. During this process, the movement trajectory of the rotating part 321 is limited by the cooperation of the limiting post 323 and the spiral rotating track 322a, so as to prevent the rotating part 321 from shaking during rotation or linear movement. This would make it difficult for the rotating bottom part 120 to be fitted onto the T-shaped limiting part 113 or for the protrusion 123 to be unable to be embedded in the slot 113c, thus ensuring the reliability of the assembly operation of the rotating fastening structure 10.

[0058] The assembly tool 30 of the present invention is suitable for the assembly operation of the aforementioned rotating fastening structure 10, which helps to improve the fastening processing efficiency of the rotating fastening structure 10, thereby improving the production efficiency and market competitiveness of the product.

[0059] The technical features of the above embodiments can be combined in any way.
