Zipper puller

Abstract

The zipper puller can realize automatic walking with simple structure, and simultaneously considers the structural strength and operation effect. The zipper puller comprises a puller body, a gear and a reset component. The puller body has a receiving part for receiving the gear on the side of a chain guide channel. The receiving part has a through hole penetrating the side of the chain guide channel. The rotation of the gear and the movement of the reset component are connected with each other. The gear and the reset component are installed on the receiving part. At least a part of the gear penetrates the through hole and is inserted into the chain guide channel from the side. Through the sliding of the puller body relative to the zipper chain, the gear rotates relative to the zipper chain. The reset component is compressed and generates a reset force through the driving of the gear. The reset force is applied to the gear through the release of the reset component. The gear reversely rotates relative to the zipper chain. The puller body reversely slides relative to the zipper chain through the driving of the gear.

Description

Technical Field

[0001] This utility model relates to the technology of zippers, and in particular to a zipper slider. Background Technology

[0002] In existing technology, a common zipper typically includes a zipper chain consisting of a pair of fastener tapes and element columns mounted on the tapes, and a zipper pull mounted on the zipper chain that opens or closes the element columns by sliding. Furthermore, a zipper tab can be provided on the zipper pull body as needed, which drives the zipper pull to slide along the zipper chain.

[0003] Furthermore, self-propelled zipper pulls capable of automatic movement have also been developed. For example, a drive source (e.g., an electric motor) can be installed on the inside (not the outside) of the zipper pull, allowing it to slide back and forth between opposite sides of the zipper chain via electric drive. Alternatively, considering automatic movement without electricity, a transmission mechanism such as gears, combined with a return component such as a coil spring, can be installed on the inside of the zipper pull. Manual drive causes the zipper pull to slide relative to one side of the zipper chain, converting the displacement into a return force. By releasing the manual drive and releasing the return force, the return force is converted back into displacement, allowing the zipper pull to automatically slide relative to the other side of the zipper chain.

[0004] However, current practices, whether installing the drive unit or gears, tend to place them on the inside of the zipper pull, thus increasing the overall size of the zipper pull in the thickness direction. This leads to user discomfort and an unnatural appearance when the zipper pull is used on clothing. Furthermore, if gears are placed on the inside of the zipper pull, the sliding vibration caused by the engagement of the gears with the zipper chain can easily cause the zipper chain to fluctuate, potentially causing parts of the zipper chain (such as teeth in the chain tooth row) to detach from the zipper pull during sliding. Therefore, it is necessary to improve the zipper pull. Utility Model Content

[0005] This utility model provides a zipper pull that can achieve automatic movement with a simple structure, while taking into account both structural strength and operational efficiency.

[0006] This utility model provides a zipper pull, comprising: a puller body adapted to be mounted on a zipper chain; a gear rotatably mounted on the puller body; and a reset member mounted on the puller body and used to apply a reset force to the gear. The puller body has an upper plate, a lower plate, a connecting post connecting the front ends of the upper plate and the lower plate, a pair of shoulder openings on the left and right sides of the connecting post, a rear opening at the rear end of the puller body, and a tooth guide channel formed between the upper plate and the lower plate and communicating between the shoulder openings and the rear opening. The puller body has a receiving portion for receiving the gear on the side of the tooth guide channel, the receiving portion having a through-feeding portion extending into the side of the tooth guide channel. The gear and the reset component are interconnected through a through hole, so that the rotation of the gear and the movement of the reset component are linked. The gear and the reset component are installed in the receiving part, and at least a portion of the gear passes through the through hole and is inserted into the zipper tooth guide channel from the side. The gear rotates relative to the zipper chain by sliding the zipper head body relative to the zipper chain, and the reset component is compressed by the drive of the gear to generate the reset force. The reset force is applied to the gear by the release of the reset component. The gear rotates in the opposite direction relative to the zipper chain, and the zipper head body slides in the opposite direction relative to the zipper chain by the drive of the gear.

[0007] In an embodiment of the present invention, the rotation center of the gear is located further rearward than the rear end of the connecting column.

[0008] In an embodiment of the present invention, the zipper pull further includes: a pull tab movably mounted on the zipper pull body; and a locking pin movably mounted on the zipper pull body and connected to the pull tab, wherein the pull tab is tilted to one side relative to the zipper pull body to engage the locking pin with a portion of the zipper chain, and the pull tab is tilted or pulled to the other side relative to the zipper pull body to release the engagement of the locking pin with the portion of the zipper chain.

[0009] In an embodiment of the present invention, in the long side direction of the zipper chain, the position where the locking pin is inserted into the zipper tooth guide channel covers the long side range of the receiving part in the long side direction.

[0010] In an embodiment of the present invention, the pull tab tilts to one side relative to the zipper head body, thereby fixing the zipper head body, the gear, and the reset component relative to the zipper chain. The pull tab tilts or pulls to the other side relative to the zipper head body, thereby releasing the reset component. The gear rotates relative to the zipper chain by the reset force, and the zipper head body slides relative to the zipper chain.

[0011] In an embodiment of the present invention, the gear and the reset component are arranged overlapping along the same axis.

[0012] In an embodiment of the present invention, the gear includes a gear body portion having a center through which the axis passes, and a shaft portion extending along the axis, the gear body portion being connected to the shaft portion in the thickness direction with respect to the center, and at least a portion of the reset member being fixed to the shaft portion.

[0013] Based on the above, in the zipper pull of this invention, the interlocking gear and the reset component are installed in a receiving portion provided on the side of the tooth guide channel of the zipper pull body, and at least a portion of the gear is inserted into the tooth guide channel from the side through a through hole. Thus, the gear and the reset component are located on one side of the zipper pull body in the width direction, thereby reducing the overall size of the zipper pull in the thickness direction. This improves user discomfort and reduces unnatural appearance when the zipper pull is used in clothing products. Furthermore, because the gear and the reset component are located on one side of the zipper pull body in the width direction, the sliding vibration caused by the engagement of the gear and the zipper chain is less likely to cause the zipper chain to fluctuate. Therefore, a portion of the zipper chain (e.g., a tooth in the tooth row) is less likely to detach from the zipper pull during sliding. Accordingly, the zipper pull of this invention can achieve automatic movement with a simple structure while simultaneously ensuring structural strength and operational efficiency.

The following pairings... Figures 1 to 8 This invention describes the specific structure and operation of the zipper pull 100 in this embodiment, but this invention is not limited thereto and can be adjusted according to requirements.

[0054] Please refer to Figures 1 to 4In this embodiment, the zipper pull 100 includes a pull body 110, a gear 120, and a reset component 130. The pull body 110 is adapted to be mounted on the zipper chain 50 (as shown by the dashed line). The gear 120 is rotatably mounted on the pull body 110. The reset component 130 is mounted on the pull body 110 and is used to apply a reset force to the gear 120. The pull body 110 has an upper plate 111, a lower plate 112, a connecting post 113 connecting the front ends of the upper plate 111 and the lower plate 112, a pair of shoulder openings 114 opening on the left and right sides of the connecting post 113, a rear opening 115 opening at the rear end of the pull body 110, and a tooth guide channel 116 formed between the upper plate 111 and the lower plate 112 and communicating with the shoulder openings 114 and the rear opening 115. Furthermore, the zipper pull body 110 also has a receiving portion 117 for receiving the gear 120 in the side portion 116a of the zipper tooth guide channel 116. The receiving portion 117 has a through hole 117a extending through the side portion 116a of the zipper tooth guide channel 116. The gear 120 is interconnected with the reset member 130, such that the rotation of the gear 120 and the movement of the reset member 130 are linked together. The gear 120 and the reset member 130 are mounted in the receiving portion 117, and are configured such that at least a portion of the gear 120 passes through the through hole 117a, and is inserted from the side portion 116a into the zipper tooth guide channel 116 (e.g., ...). Figure 4 (As shown).

[0055] Specifically, in this embodiment, as Figures 1 to 4 As shown, the zipper chain 50 includes, for example, a pair of left and right rows of teeth 52 and a pair of left and right zipper straps 54 for setting the rows of teeth 52. Here, although the zipper chain 50 is shown in the figure as a structure with a short dimension in the front-back direction X and a wide dimension in the left-right direction Y, the zipper chain 50 is actually preferably with the extension direction of the rows of teeth 52 (corresponding to the arrangement direction of the teeth), i.e., the front-back direction X, as the long side direction and the left-right direction Y as the width direction, and the zipper head body 110 of the zipper head 100 is mounted on the zipper chain 50 and is suitable for sliding relative to either side of the zipper chain 50 along the front-back direction X, i.e., the long side direction. Specifically, when the zipper pull body 110 slides relative to one side (e.g., the rear side) of the zipper chain 50 in a forward-backward direction X, the chain teeth 52 of the zipper chain 50 are open; conversely, when the zipper pull body 110 slides relative to the other side (e.g., the front side) of the zipper chain 50 in the forward-backward direction X, the chain teeth 52 are closed. However, this invention does not limit the specific structure of the zipper chain 50, which can be adjusted according to requirements.

[0056] Furthermore, in this embodiment, as Figures 1 to 4As shown, the upper plate 111 and lower plate 112 of the slider body 110 are generally plate-shaped extending on horizontal planes in the front-to-back direction X and the left-to-right direction Y, and are spaced apart in the vertical direction Z (equivalent to the thickness direction). The upper plate 111 and lower plate 112 are connected to each other at their front ends by a connecting post 113. The connecting post 113 separates a pair of shoulder openings 114 at the front end of the slider body 110, which are spaced apart in the left-to-right direction Y (equivalent to the width direction) and open outwards (front side), while the rear end of the slider body 110 forms a rear opening 115 that opens outwards (rear side). Thus, the pair of shoulder openings 114 on the front side and the rear opening 115 on the rear side are interconnected by a roughly Y-shaped chain tooth guide channel 116 between the upper plate 111 and the lower plate 112. Thus, when the zipper head body 110 slides relative to the zipper chain 50 in the forward-backward direction X on one side (e.g., the rear side), the zipper chain 50 teeth 52 are opened by separating through the connecting post 113 of the zipper head body 110, and when the zipper head body 110 slides relative to the zipper chain 50 in the forward-backward direction X on the other side (e.g., the front side), the zipper chain 50 teeth 52 are closed by being guided by the zipper head body 110 teeth guide channel 116.

[0057] Furthermore, in this embodiment, such as Figures 1 to 4 As shown, both the gear 120 and the reset component 130 are built into the slider body 110. For example, the lower plate 112 of the slider body 110 is provided as a plate or frame that is thicker than the upper plate 111, and the gear 120 and the reset component 130 are built into the space provided inside the plate or frame that serves as the lower plate 112. In detail, the receiving portion 117 of the slider body 110 is provided on the side portion 116a of the chain tooth guide channel 116. The side portion 116a is, for example, on one side in the left-right direction Y. Thus, the gear 120 and the reset component 130, which are installed in the receiving portion 117, are provided on the side portion 116a of the chain tooth guide channel 116. The junction of the receiving portion 117 and the side portion 116a, i.e., the side portion 116a, is provided with a through hole 117a that extends through the side portion 116a, i.e., the receiving portion 117 communicates with the chain tooth guide channel 116 through the through hole 117a. At least a portion of the gear 120 installed in the receiving part 117 (e.g., the portion near the side 116a) passes through the through hole 117a and is inserted from the side 116a into the chain tooth guide channel 116 (e.g. Figure 4 (As shown). That is, at least a portion of the gear 120 extends into the tooth guide channel 116. Thus, when the zipper pull 100 is installed on the zipper chain 50, at least a portion of the teeth of the gear 120 can be inserted into a portion of the tooth row 52 of the zipper chain 50 passing through the tooth guide channel 116.

[0058] In detail, in this embodiment, such as Figures 1 to 4As shown, although the gear 120 mounted in the receiving section 117 can rotate relative to the zipper head body 110, the relative position of the gear 120 and the zipper head body 110 remains unchanged. Therefore, during the sliding of the zipper head body 110 relative to the zipper chain 50, the gear 120 slides along with the zipper head body 110. The teeth of the gear 120 are pushed in one direction by a portion of the zipper chain teeth 52 that are sliding relatively within the tooth guide channel 116, thereby compressing the reset member 130 and generating a reset force. Conversely, during the process of rotating the gear 120 in the opposite direction by means such as the reset force of the reset member 130 (as explained later), the teeth of the gear 120 push a portion of the zipper chain teeth 52 in the tooth guide channel 116 to slide relatively, causing the zipper head body 110 to slide in the opposite direction relative to the zipper chain 50. Figure 4 In the schematic cross-sectional view of the bottom side of the zipper pull shown, to clearly illustrate the relative relationship between the tooth guide channel 116 of the pull body 110 and the gear 120 (arranged side by side in the width direction), the reset member 130, which is closer to the bottom side (i.e., the lower side) than the gear 120, is omitted. However, in other embodiments not shown, the gear 120 and the reset member 130 may also be located on the inner side (not the outer side) of the pull body 110. That is, the gear 120 and the reset member 130 are not limited to being completely hidden inside the pull body 110. As long as the pull body 110 is provided with a receiving portion 117 for accommodating the gear 120 and the reset member 130, its specific structure can be adjusted according to requirements.

[0059] Additionally, in this embodiment, as Figures 1 to 4 As shown, the reset member 130 is, for example, a coil spring. As an example, the gear 120 and the reset member 130 are arranged overlapping along the same axis A. The gear 120 includes a gear body portion 122 having a center C through which the axis A passes, and a shaft portion 124 extending along the axis A. The gear body portion 122 is connected to the shaft portion 124 in the thickness direction (i.e., the vertical direction Z) with respect to the center C, and is rotatably pivotally connected to the receiving portion 117 of the slider body 110 via the shaft portion 124 (e.g., ...). Figure 3 (As shown). Furthermore, the gear 120 and the reset member 130 are interconnected, for example, they are arranged overlapping in the vertical Z direction (taking the reset member 130 as an example located above the gear 120), and the rotation of the gear 120 and the movement of the reset member 130 are mutually linked. At least a portion of the reset member 130 is fixed to the shaft 124, for example, wound around the shaft 124 (e.g., ...). Figure 3As shown, the gear 120 is connected to the shaft 124 at least at one end, and can be compressed and generate a restoring force by the rotation of the gear body 122. When the gear 120 rotates in one direction, the restoring member 130 is compressed (the two ends move relative to each other) by the drive of the gear 120 and generates a restoring force. When the restoring member 130 is released and a restoring force is applied to the gear 120, the gear 120 rotates in the opposite direction by the restoring force of the restoring member 130. In this way, the gear body 122 and the shaft 124 of the gear 120 are integrated, which can shorten the length of the shaft 124, reduce the number of parts and processes, and bring production advantages. However, the present invention is not limited thereto, and can be adjusted according to needs.

[0060] Therefore, in this embodiment, as Figures 1 to 4 As shown, the operation of the zipper pull 100 includes the following steps: Manually driving the zipper pull 100 to slide relative to the zipper chain 50 to one side converts the displacement into a restoring force. Releasing the manual drive and releasing the restoring force converts the restoring force back into displacement, causing the zipper pull 100 to automatically slide relative to the zipper chain 50 to the other side. For example, the zipper pull body 110 slides relative to the zipper chain 50 to one side (e.g., manually driving the zipper pull body 110 to move it backward). Figure 4 The gear 120 slides along with the zipper head body 110, and simultaneously rotates in one direction due to the pushing of a portion of the zipper chain teeth 52 within the tooth guide channel 116. Furthermore, the reset member 130 is compressed and generates a reset force by the drive of the rotating gear 120. Conversely, when the reset member 130 is released (e.g., the manual drive of the zipper head body 110 is released), a reset force is applied to the gear 120, causing the gear 120 to rotate in the opposite direction, and simultaneously pushing a portion of the zipper chain teeth 52 within the tooth guide channel 116 to slide relative to it. Furthermore, the zipper head body 110 slides in the opposite direction relative to the zipper chain 50 along with the gear 120 (e.g., the zipper head body 110 automatically moves forward). Figure 4 (Sliding on the upper side). In this way, the zipper pull 100 uses a transmission mechanism such as gear 120 and a reset component 130 such as coil spring to move automatically, without the need for an electric motor or other power source.

[0061] With the above settings, in the zipper pull 100 of this embodiment, as follows: Figures 1 to 4As shown, the interlocking gear 120 and reset member 130 are mounted in the receiving portion 117 provided on the side 116a of the zipper tooth guide channel 116 of the zipper head body 110, and at least a portion of the gear 120 is inserted into the zipper tooth guide channel 116 from the side 116a through the through hole 117a. In this way, the gear 120 and reset member 130 are located on one side in the width direction (i.e., the left-right direction Y) of the zipper head body 110, thereby reducing the overall size of the zipper head 100 in the thickness direction (i.e., the vertical direction Z), and thus improving user discomfort and unnatural appearance when the zipper head 100 is used in clothing products. Furthermore, since the gear 120 and the reset component 130 are located on one side of the zipper head body 110 in the width direction, the sliding vibration caused by the engagement of the gear 120 and the zipper chain 50 is less likely to cause the zipper chain 50 to fluctuate. Therefore, a part of the zipper chain 50 (e.g., the teeth in the tooth row 52) is less likely to fall off the zipper head 100 during sliding. Accordingly, the zipper head 100 can achieve automatic movement with a simple structure, while simultaneously taking into account structural strength and operational efficiency.

[0062] Additionally, in this embodiment, as Figure 4 As shown, the rotation center of gear 120 (i.e., the center C of gear body portion 122 where shaft portion 124 is located) is located further rearward than the rear end of connecting post 113 (i.e., corresponding to the meshing portion in the chain tooth row 52 of zipper chain 50). Preferably, the rotation center of gear 120 (i.e., the center C of gear body portion 122 where shaft portion 124 is located) is located near the rear end of connecting post 113, so that the rotation center of gear 120 (i.e., the center C of gear body portion 122 where shaft portion 124 is located) is further rearward than the junction between the non-meshing portion of zipper chain 50 located in front of connecting post 113 and separated by connecting post 113 and the meshing portion of zipper chain 50 located behind connecting post 113 and closed. Thus, at least a portion of the zipper chain 50 (e.g., the non-engaging portion of the zipper chain 50 in the forked portion of the Y-shaped tooth guide channel 116) engages with the circumference of the gear 120 near the rear end of the connecting post 113, thereby improving the engagement effect of the gear 120 with the zipper chain 50. However, this invention is not limited thereto and can be adjusted as needed.

[0063] Furthermore, in this embodiment, as Figures 1 to 4As shown, the zipper pull 100 also includes a pull tab 140 and a locking pin 150. The pull tab 140 is movably mounted on the zipper pull body 110. The locking pin 150 is movably mounted on the zipper pull body 110 and connected to the pull tab 140. In detail, the upper plate 111 of the zipper pull body 110 also has a pull tab mounting post 118 protruding from the upper surface and a recess 119 recessed inward from the upper surface. The pull tab 140 is movably (rotatably) mounted on the zipper pull body 110 by the mounting ring 142 passing through the pull tab mounting post 118, so that the pull tab 140 can tilt and pull relative to the zipper pull body 110 in the front-back direction X (i.e., the length direction) to opposite sides, thereby causing the zipper pull body 110 to slide relative to the zipper chain 50. That is, the manual drive of the zipper pull body 110 described above can be achieved through the pull tab 140. Furthermore, the notch 119 is connected to the tooth guide channel 116. The locking pin 150 is mounted on the pull tab mounting post 118 via the mounting ring portion 142 of the pull tab 140. The insertion portion 152 at the end of the locking pin 150 is inserted into the notch 119. Thus, whether the insertion portion 152 of the locking pin 150 is inserted or not is linked to the moving direction of the pull tab 140. The insertion portion 152 can be moved through the notch 119 into the tooth guide channel 116 (i.e., the lower side) or out of the tooth guide channel 116 (i.e., the upper side) according to the drive of the pull tab 140. This allows the insertion portion 152 to be inserted into a portion of the tooth row 52 in the tooth guide channel 116 for locking, or removed from a portion of the tooth row 52 in the tooth guide channel 116 to release the lock.

[0064] Therefore, in this embodiment, as Figures 1 to 4 As shown, the zipper pull 100 not only has a gear 120 and a reset component 130 that are interconnected mounted on the pull body 110, but also a pull tab 140 and a locking pin 150 that are interconnected mounted on the pull body 110. Therefore, not only can the manual drive of the pull body 110 be achieved through the pull tab 140, but the locking of the locking pin 150 can also be achieved through the pull tab 140. For example, when the manual drive of the pull body 110 is released (e.g., when the pull tab 140 is tilted to one side relative to the pull body 110 or when it is released from pulling), the locking pin 150 engages with a portion of the chain teeth 52 of the zipper chain 50 in the chain tooth guide channel 116, so that the pull body 110 can be fixed in the current position (which can be any position on the zipper chain 50) relative to the zipper chain 50, and will not immediately slide automatically in the opposite direction relative to the zipper chain 50. In contrast, when the zipper head body 110 is manually driven (for example, when the zipper pull 140 is tilted or pulled to the other side relative to the zipper head body 110), the locking pin 150 is disengaged from a portion of the chain teeth 52 of the zipper chain 50 in the chain tooth guide channel 116, so that the zipper head body 110 can automatically slide in the opposite direction relative to the zipper chain 50 by a restoring force.

[0065] For example, in this embodiment, such as Figure 5 and Figure 6 As shown, the pull tab 140 tilts to one side relative to the zipper head body 110, causing the insertion portion 152 at the end of the locking pin 150 to move downwards towards the recess 119 (i.e., into the tooth guide channel 116), thereby engaging the locking pin 150 with a portion of the chain teeth 52 of the zipper chain 50 within the tooth guide channel 116. Thus, the pull tab 140 tilts to one side relative to the zipper head body 110, fixing the zipper head body 110, gear 120, and reset member 130 (compressed and generating a reset force) relative to the zipper chain 50. In contrast, as... Figure 7 and Figure 8 As shown, the pull tab 140 tilts or pulls to the other side relative to the zipper head body 110, causing the insertion portion 152 at the end of the locking pin 150 to move upward towards the recess 119 (i.e., outside the tooth guide channel 116), thereby releasing the locking pin 150 from the engagement of a portion of the chain teeth 52 of the zipper chain 50 within the tooth guide channel 116. Thus, the pull tab 140 tilts or pulls to the other side relative to the zipper head body 110, releasing the reset member 130, causing the gear 120 to rotate in the opposite direction relative to the zipper chain 50 by the reset force, and causing the zipper head body 110 to slide in the opposite direction relative to the zipper chain 50. Preferably, as... Figure 4 As shown, in the long side direction (i.e., the front-to-back direction X) of the zipper chain 50, the position where the locking pin 150 is inserted into the tooth guide channel 116 (i.e., the position of the insertion part 152, corresponding to the position of the notch 119) covers the long side range of the receiving part 117 in the long side direction. That is, the position where the locking pin 150 is inserted into the tooth guide channel 116 overlaps with the gear 120 received by the receiving part 117 in the long side direction (front-to-back direction X), so the locking pin 150 and the gear 120 can be regarded as being arranged side by side in the width direction (i.e., the left-to-right direction Y).

[0066] With the above configuration, in this embodiment, during the sliding of the zipper pull 100 relative to the zipper chain 50, the zipper pull 100 with automatic walking function can be easily manually driven and operated in conjunction with the pull tab 140 and locking pin 150, and then fixed in the desired current position after the operation. Furthermore, the locking pin 150 can be released by simple operation (e.g., manually driving the pull head body 110 via the pull tab 140), and at the same time as the lock is released, automatic walking is achieved via the gear 120 and the reset component 130 (e.g., automatically sliding in the reverse direction due to the reset force and linkage provided by the gear 120 and the reset component 130). During this process, since the gear 120 and the reset component 130 are located on one side of the width direction (i.e., the left-right direction Y) of the zipper head body 110, and especially since the insertion part 152 of the locking pin 150 and the gear 120 can also be considered to be arranged side by side in the width direction (i.e., the left-right direction Y), the sliding vibration caused by the engagement of the gear 120 and the zipper chain 50 is less likely to cause the zipper chain 50 to fluctuate. Therefore, the insertion part 152 of the locking pin 150 is less likely to be misaligned relative to the zipper chain 50 in the tooth guide channel 116, and can be inserted into the zipper chain 50 more accurately for locking. Accordingly, the zipper head 100 can achieve automatic movement with a simple structure, while also taking into account structural strength and operational efficiency. However, this utility model is not limited to this and can be adjusted according to needs.

[0067] In summary, in the zipper pull of this invention, the interlocking gear and the reset component are installed in a receiving portion provided on the side of the tooth guide channel of the zipper pull body, and at least a portion of the gear is inserted into the tooth guide channel from the side through a through hole. Thus, the gear and the reset component are located on one side of the width direction of the zipper pull body, thereby reducing the overall size of the zipper pull in the thickness direction. This improves user discomfort and reduces unnatural appearance when the zipper pull is used in clothing products. Furthermore, because the gear and the reset component are located on one side of the width direction of the zipper pull body, the sliding vibration caused by the engagement of the gear and the zipper chain is less likely to cause the zipper chain to fluctuate, thus preventing a portion of the zipper chain (e.g., a tooth in the tooth row) from easily detaching from the zipper pull during sliding. Preferably, the rotation center of the gear is located further rearward than the rear end of the connecting post, and at least a portion of the zipper chain engages with the circumference of the gear at the rear end of the connecting post, thereby improving the engagement effect of the gear on the zipper chain. Accordingly, the zipper pull of this utility model can achieve automatic movement with a simple structure, while taking into account both structural strength and operational efficiency.
