Description

Technical Field

[0001] The utility model relates to the technical field of zippers and their supporting components, in particular to a slider device. The utility model also relates to a zipper assembly using the slider device. Background Art

[0002] In people's daily life, zippers are a very common operating component that can be opened and closed. Especially in the processing and manufacturing of products in the fields of clothing, shoes, hats, and bags, zippers are generally used as direct operating mechanisms to help put on and take off clothing and hats, or to open and close bags.

[0003] At present, the industry usually assembles and connects zippers by assembling the zippers onto the main structure of the product after the main structure of the clothing, coats or bags has been roughly processed and formed. After that, these products assembled with zippers are further processed to improve the processing effect, thereby obtaining the final formed product.

[0004] However, although the above-mentioned zipper assembly operation and use at this stage can meet the basic application needs in the industry, the assembly method of the common zipper assembly in the industry is limited by the structure of the existing zipper assembly itself. The zipper can only be assembled on the main structure of the product after the main structure of the product such as clothing, shoes, hats and bags is roughly processed and formed. When the zipper is sewn and assembled with the main structure of the product such as clothing, shoes, hats and bags, the pull tab of the zipper will swing freely, resulting in structural interference or even collision with the needle and other moving parts of the sewing machine when the main structure of the product with the zipper is sewn. This will not only cause damage to the operating equipment such as the sewing machine, affecting the operating efficiency of the equipment, but also have an adverse effect on the product processing quality of the corresponding clothing, shoes, hats and bags, and restrict the production efficiency of the corresponding products.

[0005] In view of this, how to optimize the component structure of the zipper to avoid its pull tab and other components from having an adverse effect on the overall sewing process of the product and to ensure the overall product processing quality is an important technical problem that technical personnel in this field currently need to solve. Utility Model Content

Another purpose of the utility model is to provide a zipper assembly using the above-mentioned slider device.

[0007] In order to solve the above technical problems, the utility model provides a pull head device, comprising a pull head seat movably arranged on a chain and a pull tab linked to the pull head seat, wherein the assembly end of the pull tab has a linkage clamp ring;

[0008] A positioning curved beam is arranged above the slider seat, and the positioning curved beam can be inserted into the linkage clamp ring in a position, and the rear end of the positioning curved beam is fixedly arranged at the rear end of the top surface of the slider seat, and the bottom surface of the middle part of the positioning curved beam is matched with the gap of the top surface of the slider seat to form a linkage groove adapted to the pull tab, and the bottom surface of the front end of the positioning curved beam is matched with the gap of the top surface of the slider seat to form a pre-positioning gap for the pull tab to pass through, and the pre-positioning gap is connected with the linkage groove;

[0009] A blocking block is hinged on the positioning curved beam, and the blocking block can rotate around its hinge axis to the bottom of the positioning curved beam and block the pre-positioning gap. The slider seat is provided with a locking piece that cooperates with the blocking block to limit and fix the blocking block at the pre-positioning gap.

[0010] Preferably, the bottom surface of the blocking block has a locking hole, and the locking piece is a locking boss protruding from the top surface of the slider seat and capable of being aligned and embedded in the locking hole. When the blocking block rotates around its hinge axis to the bottom of the positioning bent beam, the locking boss can be aligned and embedded in the locking hole to clamp and lock the blocking block in the positioning gap.

[0011] Preferably, after the locking boss is embedded in the locking hole, the front end surface of the locking boss is tightly attached to and abuts against the front inner wall of the locking hole to prevent the locking boss from rotating backward around its hinge axis.

[0012] Preferably, after the locking boss is embedded in the locking hole, the rear end surface of the locking boss is tightly attached to and abuts against the rear inner wall of the locking hole to prevent the locking boss from rotating forward around its hinge axis.

[0013] Preferably, the top surface of the slider seat is a plane, and the distance between the rear end surface of the locking boss and the top surface of the slider seat increases from the back to the front.

[0014] Preferably, the top surface of the slider seat and the front end surface of the locking boss are both planes, and the front end surface of the locking boss is perpendicular to the top surface of the slider seat.

[0015] Preferably, the top end of the locking boss has a limiting flange portion, and the outer surface of the limiting flange portion is smoothly connected between the upper edge of the front end surface and the upper edge of the rear end surface of the locking boss;

[0016] The lower edge portion of the front inner wall of the locking hole is pressed and fitted with the limiting flange portion so that the limiting flange portion is elastically deformed.

[0017] Preferably, the outer surface of the limiting flange portion is an arc surface protruding toward the locking hole.

[0018] Preferably, the side wall of the front end portion of the positioning bending beam has a limiting slot adapted to the blocking block, the inner annular wall of the limiting slot is arranged in a fan shape with the hinge shaft of the blocking block as the axis, the hinge end of the blocking block is located in the limiting slot, and the inner annular wall of the limiting slot is abutted and adapted to the outer wall of the blocking block.

[0019] The utility model also provides a zipper assembly, comprising two chains arranged symmetrically and in parallel, and also comprising a pull head device adapted to the chains, wherein the pull head device is the pull head device as described in any one of the above items.

[0020] Compared with the above-mentioned background technology, the pull head device provided by the utility model uses the pull head seat as the assembly basis during its assembly and use, and the end of the pull tab close to the linkage clamp ring is the assembly end. The assembly end of the pull tab can be passed through the pre-positioning gap from the outside to the inside and continue to move appropriately until the assembly end of the pull tab is inserted into the linkage groove. At this time, the linkage clamp ring is positioned on the blocking block. After that, the staff can pull the pull tab in the opposite direction, that is, drive the pull tab to move along the direction of withdrawing from the linkage groove from the inside to the outside. In this process, since the blocking block has been inserted into the linkage clamp ring, the blocking block and the linkage clamp ring form a linkage, so that the pull tab is used to drive the blocking block to move along the direction of withdrawing from the linkage groove from the inside to the outside. The zipper is then moved back and forth between the sliding block and the sliding block, and the sliding block is moved back and forth between the sliding block and the sliding block, so that the sliding block can move back and forth along the sliding block to form a reliable structural seal for the pre-positioned gap. In addition, since the zipper is always inserted in the linkage clamping ring, the linkage clamping ring can be reliably mounted on the zipper and the positioning bent beam that is structurally connected to the zipper. During the subsequent operation of the zipper, the user can pull the pull tab to realize the linkage pulling of the slider seat, thereby realizing the overall operation of the slider device, which is convenient for controlling the slider device to move back and forth along the chain, thereby realizing the opening or closing of the zipper assembly. In addition, by reliably blocking the pre-positioning gap with the blocking block, the structural gap or matching gap of the linkage clamp removed from the positioning curved beam and the blocking block can be completely closed, so that the pull tab can be reliably linked and assembled on the slider seat, and the assembly end of the pull tab is encapsulated in the linkage groove, thereby effectively preventing the pull tab from falling off the slider seat, and realizing the reliable assembly of the main assembly of the slider device. On this basis, since the assembly process between the pull tab and the slider seat can be implemented at any time without the need for specific process requirements such as pre-assembly, when the slider device is assembled on the main structure of clothing, shoes, hats or bags, the slider seat can be assembled with the corresponding main structure first, and then the corresponding sewing or other deep processing processes can be completed. During this period, since the pull tab is not assembled on the slider seat, the adverse effects of the free swing of the pull tab on the corresponding product sewing and other processing processes are effectively avoided, and the corresponding product processing quality is fully guaranteed. After the apparel, shoes, hats or bags are basically processed and formed, the pull tabs are assembled to the slider seat using the assembly operation steps described above, thereby completing the overall assembly of the slider device. In this way, by optimizing the assembly structure of the slider device, the pull tab assembly of the slider device is freed from the implementation order requirements of specific processes, so that the pull tabs can be assembled to the slider seat after the corresponding apparel, shoes, hats or bags are basically processed, thereby effectively avoiding the adverse effects of free swinging parts such as pull tabs on the overall sewing of the product, ensuring the overall processing quality of the product, and optimizing the product processing process layout accordingly, and improving production efficiency accordingly.

[0021] In another preferred embodiment of the present invention, the bottom surface of the blocking block has a locking hole, and the locking piece is a locking boss protruding from the top surface of the slider seat and capable of being aligned and embedded in the locking hole. When the blocking block rotates around its hinge axis to the bottom of the positioning bent beam, the locking boss can be aligned and embedded in the locking hole to clamp and lock the blocking block in the positioning gap. The locking protrusion is then moved forwards to lock the locking member in the locking state, and the locking member is engaged with the locking member so that the locking member can be reliably locked in the locking state.

[0037] The core of the utility model is to provide a slider device, the component adaptation and component assembly structure of the slider device are relatively reasonable, which can effectively prevent the pull tab and other components from causing adverse effects on the overall sewing process of the product, thereby ensuring the overall product processing quality; in addition, a zipper assembly using the above-mentioned slider device is also provided.

[0038] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] Please refer to Figures 1 to 8 .

[0040] In a specific embodiment, the slider device provided by the utility model includes a slider seat 11 movably arranged on a chain and a pull tab 12 linked to the slider seat 11, and the assembly end of the pull tab 12 has a linkage clamp ring 121;

[0041] A positioning curved beam 13 is arranged above the slider seat 11. The positioning curved beam 13 can be inserted into the linkage clamp ring 121 in a aligned manner. The rear end of the positioning curved beam 13 is fixedly arranged at the rear end of the top surface of the slider seat 11. The middle bottom surface of the positioning curved beam 13 is gap-matched with the top surface of the slider seat 11 to form a linkage groove 111 adapted to the pull tab 12. The bottom surface of the front end of the positioning curved beam 13 is gap-matched with the top surface of the slider seat 11 to form a pre-positioning gap 112 for the pull tab 12 to pass through. The pre-positioning gap 112 is connected to the linkage groove 111.

[0042] A blocking block 14 is hinged on the positioning curved beam 13, and the blocking block 14 can rotate around its hinge axis to the bottom of the positioning curved beam 13 and block the pre-positioning gap 112. A locking member is provided on the slider seat 11 to cooperate with the blocking block 14 to limit and fix the blocking block 14 at the pre-positioning gap 112.

[0043] During its assembly and use, the slider seat 11 is used as the assembly basis, and the end of the pull tab 12 close to the linkage snap ring 121 is the assembly end. The assembly end of the pull tab 12 can be passed through the pre-positioning gap 112 from the outside to the inside and continue to move appropriately until the assembly end of the pull tab 12 is inserted into the linkage groove 111. At this time, the linkage snap ring 121 is aligned and sleeved on the blocking block 14. After that, the staff can pull the pull tab 12 in the reverse direction, that is, drive the pull tab 12 to move in the direction of withdrawing from the linkage groove 111 from the inside to the outside. In this process, since the blocking block 14 has been inserted into the linkage snap ring 121, the blocking block 14 and the linkage snap ring 121 form a linkage, so that the pull tab 12 is used to drive the blocking block 14 to move along the movement trend of withdrawing from the linkage groove 111 from the inside to the outside. The blocking block 14 rotates around its hinge axis toward the front end of the slider seat 11 under this moving trend until the free end edge of the blocking block 14 abuts against and presses the top surface of the slider seat 11, so that the blocking block 14 can form a reliable structural blockage for the pre-positioning gap 112, and because the blocking block 14 is always inserted in the linkage snap ring 121, the linkage snap ring 121 can be reliably mounted on the blocking block 14 and the positioning bent beam 13 that is structurally connected to the blocking block 14, so that during the subsequent zipper operation, the user can pull the pull tab 12 to achieve the linkage pulling of the slider seat 11, thereby achieving the overall operation of the slider device, which is convenient for controlling the slider device to move back and forth along the chain, thereby achieving the opening or closing of the zipper assembly.

[0044] In addition, by reliably sealing the pre-positioning gap 112 using the blocking block 14, the structural gap or matching gap in which the linkage clamp 121 is removed from the positioning bending beam 13 and the blocking block 14 can be completely closed, so that the pull tab 12 can be reliably linked and assembled on the slider seat 11, and the assembly end of the pull tab 12 can be encapsulated in the linkage groove 111, thereby effectively preventing the pull tab 12 from falling off the slider seat 11, thereby achieving reliable assembly of the main components of the slider device.

[0045] On this basis, since the assembly process between the pull tab 12 and the slider seat 11 can be implemented at any time without specific process requirements such as pre-assembly, when the slider device is assembled on the main structure of clothing, shoes, hats or bags, the slider seat 11 can be assembled with the corresponding main structure first, and then the corresponding sewing or other deep processing steps can be completed. During this period, since the pull tab 12 is not assembled on the slider seat 11, the adverse effects of the free swing of the pull tab 12 on the sewing and other processing techniques of the corresponding products are effectively avoided, and the processing quality of the corresponding products is fully guaranteed.

[0046] After the apparel, shoes, hats or bags are basically processed and formed, the pull tab 12 is assembled to the slider seat 11 using the assembly steps described above, so as to complete the overall assembly of the slider device. In this way, by optimizing the assembly structure of the slider device, the assembly of the pull tab 12 of the slider device is freed from the implementation order requirements of specific processes, so that the pull tab 12 can be assembled to the slider seat 11 after the corresponding apparel, shoes, hats or bags are basically processed. This effectively avoids the adverse effects of free-swinging parts such as the pull tab 12 on the overall sewing of the product, ensures the overall processing quality of the product, and optimizes the arrangement of the product processing procedures accordingly, thereby improving production efficiency accordingly.

[0047] Generally, one end of the pull tab 12 is an assembly end that can be connected to the slider seat 11, and the other end is a control end that can be pinched or held by the user's fingers when the zipper assembly is in use. Considering that the pull tab 12 is usually a long strip structure, the assembly end and the control end are respectively located at the two ends of the pull tab 12 in the length direction, and the linkage pull ring is located at the assembly end of the pull tab 12. In addition, an assembly ring 122 with a ring structure similar to the linkage pull ring can also be arranged at the control end of the pull tab 12 to hang or tie some ornaments or accessories that can be matched with corresponding clothing, shoes, hats, bags, etc., so as to further optimize the overall product consistency of the zipper assembly with clothing, shoes, hats, bags, etc., and make the zipper assembly more beautiful and practical.

[0048] It is not difficult to understand that the determination of the "front" and "rear" directions mentioned in this solution is based on the length direction of the slider seat 11, that is, based on the reciprocating direction of the slider seat 11 along the chain. It can also be understood that the length direction of the chain is the reference. Referring to the figures of this solution, generally, when the slider seat 11 moves along the length direction of the chain to close the two chains, the end facing the forward direction is the front end of the slider seat 11, and correspondingly, the end of the slider seat 11 opposite to the front end in the length direction is the rear end of the slider seat 11. Figure 3 For example, Figure 3In the middle paper direction, the left end of the slider seat 11 is the front end of the slider seat 11, and the right end of the slider seat 11 is the rear end of the slider seat 11. Accordingly, Figure 3 The pull tab 12 shown in the figure is now in the front position of the slider seat 11. Figure 7 and Figure 8 For example, Figure 7 and Figure 8 In the embodiment, the left end of the slider seat 11 is the rear end of the slider seat 11, and the right end of the slider seat 11 is the front end of the slider seat 11. Accordingly, Figure 7 and Figure 8 The pull tab 12 shown in the figure is located at the front of the slider seat 11. The relative positions of the components in the remaining figures of this scheme can be understood by referring to this, and no further description is given.

[0049] On this basis, the directional expressions of "front" in the rest of the content of this solution are consistent with the front end determination criteria of the slider seat 11, that is, the position close to the front end relative to the main structure of the slider seat 11; and the directional expressions of "rear" in this solution are the position close to the rear end relative to the main structure of the slider seat 11. Unless otherwise specified, the directional determination criteria of "front" and "rear" in this solution can be understood by referring to the corresponding references here and will not be repeated.

[0050] Specifically, the bottom surface of the blocking block 14 has a locking hole 141, and the locking piece is a locking boss 15 protruding from the top surface of the slider seat 11 and capable of being aligned and embedded in the locking hole 141. When the blocking block 14 rotates around its hinge axis to the bottom of the positioning bent beam 13, the locking boss 15 can be aligned and embedded in the locking hole 141 to lock the blocking block 14 in the positioning gap.

[0051] In the process that the pull tab 12 relies on the linkage clamping ring 121 to drive the blocking block 14 to swing around its hinge axis toward the front end of the slider seat 11, the bottom end of the blocking block 14 gradually approaches the locking boss 15 until the front end inner wall of the locking hole 141 passes through the locking boss 15 from back to front, so that the locking boss 15 is aligned and inserted into the locking hole 141. After that, the blocking block 14 continues to swing forward moderately around its hinge axis for a distance until the blocking block 14 reliably blocks the pre-positioning gap 112 and enables the locking boss 15 to be completely embedded in the locking hole 141 and reliably snap-fitted and assembled with the locking hole 141. At this time, the locking boss 15 can be used to The embedded card connection between 15 and the locking hole 141 realizes the reliable locking of the position of the blocking block 14 to prevent the blocking block 14 from rotating backward or forward around its hinge axis from the current position, thereby preventing the blocking block 14 from loosening or dislocating due to further rotation of the blocking block 14 in the current blocking position, and avoiding the pre-positioning gap 112 being reopened due to this, thereby preventing the pull tab 12 from escaping through the reopened pre-positioning gap 112, thereby further ensuring the assembly reliability of the pull tab 12 and the slider seat 11, and making the component structure of the slider device more stable and reliable.

[0052] After the slider device is assembled, the positioning bent beam 13 and the blocking block 14 can both pass through the linkage snap ring 121 and cooperate with the linkage snap ring 121 along the radial clearance respectively, so that the linkage snap ring 121 is sleeved on the annular support structure formed by the smooth connection between the positioning bent beam 13 and the blocking block 14, so as to meet the subsequent user's operational requirements of grasping and holding the pull tab 12 to drive the slider seat 11 to move back and forth synchronously along the length direction of the chain, thereby realizing the overall closing and opening of the zipper assembly.

[0053] More specifically, after the locking boss 15 is inserted into the locking hole 141, the front end face 151 of the locking boss 15 is tightly attached to and abuts against the front inner wall of the locking hole 141, so as to prevent the locking boss 15 from rotating backward around its hinge axis. In this way, the surface contact between the front end face 151 of the locking boss 15 and the front inner wall of the locking hole 141 is utilized to optimize the embedded card-fitting effect between the locking boss 15 and the locking hole 141, optimize the corresponding contact stress distribution, avoid the problem of excessive stress concentration under the contact adaptation structure such as line contact or point contact, and thus make the locking boss 15 more reliable in limiting the backward movement trend of the blocking block 14.

[0054] Correspondingly, after the locking boss 15 is inserted into the locking hole 141, the rear end face 152 of the locking boss 15 is tightly fitted and abutted against the rear inner wall of the locking hole 141 to prevent the locking boss 15 from rotating forward around its hinge axis. Similar to the surface contact adaptation structure between the front end face 151 of the locking boss 15 and the front inner wall of the locking hole 141 mentioned above, the surface contact adaptation structure formed by the fit and abutment between the rear end face 152 of the locking boss 15 and the rear inner wall of the locking hole 141 can also optimize the embedded card-connection adaptation effect between the locking boss 15 and the locking hole 141, optimize the corresponding contact stress distribution, avoid the problem of excessive stress concentration under the contact adaptation structure such as line contact or point contact, and thereby make the locking boss 15 more reliable in limiting the forward movement trend of the blocking block 14.

[0055] In order to further optimize the matching effect between the locking boss 15 and the locking hole 141, the top surface of the slider seat 11 is a plane, and the distance between the rear end surface 152 of the locking boss 15 and the top surface of the slider seat 11 increases from the back to the front, so that the rear end surface 152 of the locking boss 15 forms a slope structure with a high front and a low back.

[0056] In addition, the front end face 151 of the locking boss 15 is a plane, and the front end face 151 of the locking boss 15 is perpendicular to the top surface of the slider seat 11, so that the front end face 151 of the locking boss 15 and the rear end face 152 of its inclined structure cooperate with each other, so that the locking boss 15 can form a horizontal triangular prism structure parallel to the top surface of the slider seat 11 in the height direction, thereby further optimizing the overall stress distribution of the locking boss 15 and enabling the locking boss 15 to be more smoothly embedded in the locking hole 141, so that the embedded card connection between the locking boss 15 and the locking hole 141 is more stable and reliable, and the locking and limiting effect of the blocking block 14 is better.

[0057] Furthermore, the top of the locking boss 15 has a limiting flange 153, and the outer surface of the limiting flange 153 is smoothly connected between the upper edge of the front end face 151 and the upper edge of the rear end face 152 of the locking boss 15; the lower edge of the front inner wall of the locking hole 141 is pressed and adapted with the limiting flange 153, so that the limiting flange 153 is elastically deformed. Under the linkage action of the linkage clamp 121, the blocking block 14 moves from back to front along with the pull tab 12. When the bottom front end of the blocking block 14 reaches the matching position of the locking boss 15, the lower edge of the front inner wall of the locking hole 141 will moderately abut against the limiting flange 153, so that the limiting flange 153 blocks the movement trend of the blocking block 14 to continue to rotate forward around the hinge axis. At this time, the pull tab 12 is continuously pulled forward, thereby driving the blocking block 14 to press the limiting flange 153, so that The limiting flange portion 153 forms a certain degree of elastic deformation and sinks to leave a structural space sufficient for the lower edge portion of the front end surface 151 of the locking hole 141 to pass through, thereby allowing the blocking block 14 to overcome the structural resistance at the limiting flange portion 153 under the linked pulling action of the pull tab 12 and continue to rotate forward until the bottom surface of the blocking block 14 can be fully fitted and reliably pressed against the top surface of the slider seat 11, so that the blocking block 14 can reliably block the pre-positioning gap 112. Among them, when the lower edge of the front inner wall of the locking hole 141 overcomes the abutment resistance at the limiting flange portion 153 and passes through the limiting flange portion 153, the limiting flange portion 153 is no longer subjected to structural pressure, so the elastic deformation of the structure is released and the original state is restored, thereby allowing the limiting flange portion 153 after restoration to be aligned and extended into the locking hole 141, and then the blocking block 14 continues to rotate forward around its hinge axis until the rear inner wall of the locking hole 141 is pressed and fitted with the rear end face 152 of the locking boss 15, thereby forming a reliable snap-fit ​​installation between the locking boss 15 and the locking hole 141, and thereby achieving reliable limiting locking of the blocking block 14.

[0058] It is not difficult to understand that in actual applications, the limiting flange portion 153 should be made of a metal material or non-metal material with a certain elastic deformation ability. Considering that the limiting flange portion 153 is generally integrally formed on the locking boss 15, the locking boss 15 should be made of a metal or non-metal part with a certain elastic deformation ability.

[0059] Furthermore, the outer surface of the limiting flange 153 is an arc surface protruding toward the locking hole 141. The arc surface structure can further optimize the adaptation effect between the limiting flange 153 and the blocking block 14, especially facilitate the structural deformation formed by pressing the limiting flange 153 to release the abutment of the limiting flange 153 on the lower edge of the front inner wall of the locking hole 141, and avoid the limiting flange 153 and the lower edge of the front inner wall of the locking hole 141 from being completely stuck, so as to prevent the blocking block 14 from being completely stuck at the rear side of the locking boss 15 and being unable to complete the continued forward movement and the blocking of the pre-positioning gap 112.

[0060] It should be noted that, in actual applications, the boss-like structure arranged on the top surface of the slider seat 11 is only a better application form of the locking member. The specific structural shape of the locking member and its adaptation form with the slider seat 11 and the blocking member are not limited to those described above. Depending on the actual assembly working conditions, the locking member can also be a buckle arranged at the front end of the positioning curved beam 13 and capable of adapting to the blocking block 14, or a locking pin capable of cooperating with the pin shaft of the blocking block 14 and other types of locking components. In actual applications, the staff can flexibly select and adjust the specific structural type of the locking member and its adaptation method with related matching parts according to the specific working conditions and in combination with the actual assembly conditions. In principle, any structure that can meet the actual application needs of the slider device is acceptable.

[0061] On the other hand, the side wall of the front end of the positioning curved beam 13 is provided with a limiting card slot 131 adapted to the blocking block 14, the inner ring wall of the limiting card slot 131 is arranged in a fan shape with the hinge axis of the blocking block 14 as the axis, the hinge end of the blocking block 14 is located in the limiting card slot 131, and the inner ring wall of the limiting card slot 131 is abutted and adapted to the outer wall of the blocking block 14. The limiting card slot 131 can reliably adapt to the hinge end of the blocking block 14, thereby limiting the front and rear limit positions of the blocking block 14 when rotating around its hinge axis, so as to prevent the blocking block 14 from being loosened or misplaced during the rotation process around its hinge axis, ensure the tracking performance of the blocking block 14, and thereby ensure the alignment accuracy and blocking effect of the blocking block 14 and the pre-positioning gap 112. There can be only one limiting slot 131, which can be arranged on either side of the positioning curved beam 13; or a limiting slot 131 can be symmetrically arranged on both sides of the front end of the positioning curved beam 13 to further optimize the limiting adaptation effect on the hinged end of the blocking block 14.

[0062] Specifically in the actual assembly, a main shaft hole 132 can be arranged in the middle of the limiting slot 131 and penetrates the front end of the positioning bent beam 13 along the width direction of the slider seat 11, and a secondary shaft hole 142 penetrating along the width direction is also arranged accordingly at the top of the blocking block 14. In this way, the blocking block 14 and the positioning bent beam 13 are hingedly assembled by using an axle pin 143 coaxially inserted in the main shaft hole 132 and the secondary shaft hole 142, and the axis of the axle pin 143 is the hinged rotation axis of the blocking block 14.

[0063] In addition, the bottom surface of the blocking block 14 should be a smooth plane to ensure that the bottom surface of the blocking block 14 can be fully attached to and reliably pressed against the top surface of the slider seat 11 , thereby further ensuring the sealing effect of the blocking block 14 on the pre-positioning gap 112 .

[0064] In a specific embodiment, the zipper assembly provided by the utility model includes two chains arranged symmetrically and in parallel, and also includes a pull head device adapted to the chain, and the pull head device is the pull head device described above. The pull head device of the zipper assembly can effectively prevent the pull tab and other components from causing adverse effects on the overall sewing process of the product, thereby ensuring the overall product processing quality.

[0065] In summary, it can be seen that during the assembly and use of the slider device provided in the utility model, the slider seat is used as the assembly basis, and the end of the pull tab close to the linkage clamp ring is the assembly end. The assembly end of the pull tab can be passed through the pre-positioning gap from the outside to the inside and continue to move appropriately until the assembly end of the pull tab is inserted into the linkage groove. At this time, the linkage clamp ring is positioned on the blocking block. After that, the staff can pull the pull tab in the opposite direction, that is, drive the pull tab to move in the direction of withdrawing from the linkage groove from the inside to the outside. In this process, since the blocking block has been inserted into the linkage clamp ring, the blocking block and the linkage clamp ring are linked, so that the pull tab is used to drive the blocking block to move together along the direction of withdrawing from the linkage groove from the inside to the outside. The blocking block moves around its hinge axis toward the front end of the slider seat under this moving trend until the free end edge of the blocking block abuts against and presses the top surface of the slider seat, so that the blocking block can form a reliable structural blockage for the pre-positioning gap, and because the blocking block is always inserted in the linkage clamping ring, the linkage clamping ring can be reliably sleeved on the blocking block and the positioning bent beam that is structurally connected to the blocking block, so that during the subsequent zipper operation, the user can pull the pull tab to realize the linkage pulling of the slider seat, thereby realizing the overall operation of the slider device, which is convenient for controlling the slider device to move back and forth along the chain, thereby realizing the opening or closing of the zipper assembly. In addition, by reliably blocking the pre-positioning gap with the blocking block, the structural gap or matching gap of the linkage clamp removed from the positioning curved beam and the blocking block can be completely closed, so that the pull tab can be reliably linked and assembled on the slider seat, and the assembly end of the pull tab is encapsulated in the linkage groove, thereby effectively preventing the pull tab from falling off the slider seat, and realizing the reliable assembly of the main assembly of the slider device. On this basis, since the assembly process between the pull tab and the slider seat can be implemented at any time without the need for specific process requirements such as pre-assembly, when the slider device is assembled on the main structure of clothing, shoes, hats or bags, the slider seat can be assembled with the corresponding main structure first, and then the corresponding sewing or other deep processing processes can be completed. During this period, since the pull tab is not assembled on the slider seat, the adverse effects of the free swing of the pull tab on the corresponding product sewing and other processing processes are effectively avoided, and the corresponding product processing quality is fully guaranteed. After the apparel, shoes, hats or bags are basically processed and formed, the pull tabs are assembled to the slider seat using the assembly operation steps described above, thereby completing the overall assembly of the slider device. In this way, by optimizing the assembly structure of the slider device, the pull tab assembly of the slider device is freed from the implementation order requirements of specific processes, so that the pull tabs can be assembled to the slider seat after the corresponding apparel, shoes, hats or bags are basically processed, thereby effectively avoiding the adverse effects of free swinging parts such as pull tabs on the overall sewing of the product, ensuring the overall processing quality of the product, and optimizing the product processing process layout accordingly, and improving production efficiency accordingly.

[0066] The utility model also provides a zipper assembly, the component adaptation and component assembly structure of the pull head device of which are relatively reasonable, which can effectively prevent the pull tab and other components from causing adverse effects on the overall sewing process of the product, thereby ensuring the overall product processing quality.

It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
