Description

Technical Field

[0001] This application relates to the field of garment accessories, and more specifically, to a zipper. Background Technology

[0002] Zippers are connectors used to close the openings of clothing and bags.

[0003] In existing technology, when zipping up a zipper, the zipper pull must first be pulled back to the bottom, and after confirming that the zipper pull is aligned with the square socket at the bottom, the insert pin is inserted, and finally the zipper pull is pulled upwards. The above method is relatively cumbersome to operate when zipping up a zipper, and requires alignment confirmation to ensure that the insert pin is inserted in place; otherwise, it is easy to cause misalignment of the zipper teeth.

[0004] In conclusion, how to improve the efficiency of zipper operation is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this application is to provide a zipper that not only improves the efficiency of zipping but also prevents misalignment of the zipper teeth when zipping.

[0006] To achieve the above objectives, this application provides a zipper, comprising: a sub-chain and a main chain, and further comprising: a square socket disposed at one end of the main chain; a slidable zipper head disposed on the main chain and having a hook; and an insert pin disposed at one end of the sub-chain and opposite to the square socket. When the insert pin is inserted into the zipper head, one end of the hook is lifted to engage the insert pin, so that the insert pin can drive the hook to move in a direction closer to the square socket, thereby moving the zipper head to the square socket.

[0007] Preferably, the top of the insert pin is provided with a locking groove, which extends along the length of the insert pin. When the insert pin is inserted into the pull head, one end of the hook falls into the locking groove.

[0008] Preferably, the width of the snap-fit ​​groove gradually increases along the direction close to the square socket.

[0009] Preferably, the side of the snap-fit ​​groove closest to the block socket is sloped so that the hook can disengage from the snap-fit ​​groove.

[0010] Preferably, the insert pin includes a first pin and a second pin connected to each other, the first pin being used to insert into the block socket, the second pin being used to insert into the pull head, and the snap-fit ​​groove being provided at the top of the first pin or the second pin.

[0011] Preferably, the zipper pull includes: an upper base; a lower base, which is vertically corresponding to the upper base and forms a first channel for the mother chain to pass through and a second channel for the insert pin to pass through; a positioning groove, which is provided on the upper base for fixing one end of the hook; and a self-locking hole, which is provided on the upper base and spaced apart from the positioning groove along the length of the upper base, and the self-locking hole connects the first channel and the second channel for the other end of the hook to pass through.

[0012] Preferably, the hook includes: a positioning hook that engages with the positioning groove; a connecting portion that connects one end to the positioning hook; and a self-locking hook that connects to the other end of the connecting portion, passes through the self-locking hole to abut against the mother chain, and the bottom end of the self-locking hook extends into the second channel in a direction perpendicular to the mother chain, so as to engage the inserting pin when the inserting pin is inserted into the second channel.

[0013] Preferably, when the self-locking hook engages with the insert pin, the side of the self-locking hook that abuts against the insert pin is vertical, so as to prevent the self-locking hook from disengaging from the insert pin when the insert pin moves closer to the square socket.

[0014] Preferably, the side of the self-locking hook facing the second channel is an inclined surface, and the end of the inclined surface closer to the first channel is higher than the end closer to the second channel.

[0015] Preferably, it further includes: a fixing pin, disposed inside the block socket and connected to the mother chain, having a limiting groove, and the inserting pin having a limiting protrusion corresponding to the limiting groove, wherein when the inserting pin is inserted into the block socket, the limiting protrusion is used to insert into the limiting groove.

[0016] Compared to the aforementioned background technology, the insert pin provided in this application adds a locking groove, and one end of the hook is located inside the zipper head and offset from the center of the zipper head. This allows the offset end of the hook to be lifted when the insert pin is inserted into the zipper head. As the insert pin moves closer to the zipper head, the hook falls into the locking groove and is locked, thus moving with the insert pin. In this way, when pulling the zipper, the zipper does not need to be fully pulled to align with the lower square socket, avoiding the problem of misalignment of the zipper teeth due to misalignment between the zipper head and the square socket, and improving the efficiency of pulling the zipper.

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] This application provides a zipper, including a sub-chain 60 and a main chain 70, as well as a square socket 50, a zipper pull 20, and a locking pin 10. The square socket 50 is located at one end of the main chain 70; the zipper pull 20 is slidably mounted on the main chain 70 and has a hook 30; the locking pin 10 is located at one end of the sub-chain 60 and is positioned opposite the square socket 50. When the locking pin 10 is inserted into the zipper pull 20, one end of the hook 30 is lifted to engage the locking pin 10, allowing the locking pin 10 to move the hook 30 towards the square socket 50, thereby moving the zipper pull 20 to the square socket 50.

[0034] Specifically, the insert pin 10 is equipped with a locking mechanism, and one end of the hook 30 is located inside the zipper pull 20, offset from the center of the zipper pull 20. When the zipper is pulled, the insert pin 10 is inserted into the zipper pull 20, and the offset end of the hook 30 hooks onto the insert pin 10, thus moving with the insert pin 10 in a direction close to the zipper pull 20. During the movement, the offset end of the hook 30 deviates further from the center of the zipper pull 20, biased towards the insert pin 10. In this way, when pulling the zipper, the zipper does not need to be pulled all the way to align with the lower square socket 50, avoiding the problem of misalignment of the zipper teeth due to misalignment between the zipper pull 20 and the square socket 50, and improving the efficiency of pulling the zipper.

[0035] The aforementioned snap-fit ​​component can be the snap-fit ​​slot 11, or other structures that can be hooked by the hook 30 and play a driving role; this article does not limit it.

[0036] When the insert pin 10 drives the zipper head 20 back to its original position, lift the hook 30 to unlock it, and at the same time push the insert pin 10 into the square socket 50, then you can pull up the zipper.

[0037] In some embodiments, the top end of the insert pin 10 is provided with a snap-fit ​​groove 11, which extends along the length of the insert pin 10. When the insert pin 10 is inserted into the pull head 20, one end of the hook 30 falls into the snap-fit ​​groove 11.

[0038] Specifically, when the insert pin 10 is inserted into the pull head 20, one end of the insert pin 10 will push up the hook 30. Then, the insert pin 10 is pushed in, and the hook 30 will fall into the pre-set snap-fit ​​slot 11. At this time, the hook 30 has hooked the insert pin 10, and the insert pin 10 can drive the pull head 20 to move to the block socket 50.

[0039] In some embodiments, the width of the snap-fit ​​slot 11 gradually increases along the direction close to the square socket 50.

[0040] In other words, when the hook 30 moves together with the insert pin 10, the hook 30 abuts against one side of the locking groove 11 along its length, and the width of the abutting end is relatively small. This effectively prevents the hook 30 from moving along the width of the locking groove 11 when the insert pin 10 moves the hook 30, ensuring stable movement of the hook 30. Furthermore, the side of the locking groove 11 that abuts against the hook 30 is a transitional arc surface to prevent the hook 30 from disengaging from the locking groove 11 during movement, providing a limiting function.

[0041] In some embodiments, the side of the snap-fit ​​groove 11 near the block socket 50 is a ramp 111 so that the hook 30 can be disengaged from the snap-fit ​​groove 11.

[0042] Specifically, the side of the locking groove 11 that is not locked to the hook 30 is a steeply sloped transition surface so that when the insert pin 10 is pulled outward, it can smoothly disengage from the restriction of the rear tip of the hook 30 from this side.

[0043] In some embodiments, the insert pin 10 includes a first pin 13 and a second pin 14 connected to each other. The first pin 13 is used to insert into the block socket 50, and the second pin 14 is used to insert into the pull head 20. The snap-fit ​​groove 11 is provided at the top of the first pin 13 or the second pin 14.

[0044] Specifically, the insertion pin 10 is positioned so that one side gradually approaches the other side in the width direction. That is, the width of the first pin 13 is smaller than the width of the second pin 14. Since the width of the snap-fit ​​groove 11 gradually increases in the direction close to the square socket 50, when the snap-fit ​​groove 11 is located at the upper end of the first pin 13, the snap-fit ​​groove 11 is inclined.

[0045] When the slot 11 is located at the upper end of the second pin 14, the inserting pin 10 drives the pull head 20 to move until it is aligned with the square socket 50. At the same time, the first pin 13 is also inserted into the square socket 50. At this time, you can simply pull up the zipper.

[0046] In some embodiments, the zipper pull 20 includes an upper base 21, a lower base 22, a positioning groove 24, and a self-locking hole 25. The lower base 22 is vertically aligned with the upper base 21, forming a first channel for the female chain 70 to pass through and a second channel for the insertion pin 10 to pass through. The positioning groove 24 is located on the upper base 21 and is used to fix one end of the hook 30. The self-locking hole 25 is located on the upper base 21 and is spaced apart from the positioning groove 24 along the length of the upper base 21. The self-locking hole 25 connects the first channel and the second channel, allowing the other end of the hook 30 to pass through.

[0047] With attachment Figure 3 With the orientation as a reference, the positioning groove 24 and the self-locking hole 25 are located in the middle of the upper base 21. The side of the positioning groove 24 away from the self-locking hole 25 is a limiting slope 23, which contacts the front protrusion of the hook 30 and serves as a limit. A limiting platform 26 is provided on the side of the self-locking hole 25 away from the positioning groove 24, which contacts the rear protrusion of the hook 30, keeping the front and rear ends of the hook 30 at a set depth position and preventing the hook 30 from falling when not in motion. Furthermore, chamfers are made on both sides of the width direction of the self-locking hole 25 to facilitate lifting the hook 30 when not in motion, serving as a transition.

[0048] In some embodiments, the hook 30 includes a positioning hook 31, a connecting portion 32, and a self-locking hook 33. The positioning hook 31 engages with the positioning groove 24; one end of the connecting portion 32 is connected to the positioning hook 31; the self-locking hook 33 is connected to the other end of the connecting portion 32, passes through a self-locking hole 25 to abut against the main chain 70, and the bottom end of the self-locking hook 33 extends into the second channel in a direction perpendicular to the main chain 70, so as to engage the inserting pin 10 when the inserting pin 10 is inserted into the second channel.

[0049] Specifically, the positioning hook 31 and the self-locking hook 33 are located on the same side of the connecting part 32, and their concave surfaces are arranged in the same direction. Of course, the shape of the hook 30 is not limited in this article, as long as it can hook the insert pin 10 and make it drive the pull head 20 to move.

[0050] In some embodiments, when the self-locking hook 33 engages with the insert pin 10, the side of the self-locking hook 33 that abuts against the insert pin 10 is a vertical surface, which prevents the self-locking hook 33 from disengaging from the insert pin 10 when the insert pin 10 moves close to the block socket 50.

[0051] With attachment Figure 6 With the orientation as a reference, when the self-locking hook 33 engages with the inserting pin 10, the side of the self-locking hook 33 facing the positioning hook 31 is vertically downward, and the side facing away from the positioning hook 31 is concave downward, so that when the hook 30 moves, it can increase the contact force with the inserting pin 10, thereby further preventing it from disengaging from the inserting pin 10.

[0052] In some embodiments, the side of the self-locking hook 33 facing the second channel is an inclined surface, with the end of the inclined surface closer to the first channel being higher than the end closer to the second channel.

[0053] In some embodiments, the zipper further includes a fixing pin 80 disposed in the block socket 50 and connected to the mother chain 70, having a limiting groove 81, and the inserting pin 10 having a limiting protrusion 12 corresponding to the limiting groove 81. When the inserting pin 10 is inserted into the block socket 50, the limiting protrusion 12 is used to insert into the limiting groove 81.

[0054] Specifically, a limiting groove 81 is provided along the side wall of the end face of the fixing pin 80 that is not inserted into the square socket 50. The opening of the limiting groove 81 is set towards the insertion pin 10. Correspondingly, the side of the insertion pin 10 facing the limiting groove 81 is provided with an outwardly extending limiting protrusion 12.

[0055] The zipper also includes a cap 40, one end of which is located on the mounting groove of the upper base 21, and the other end is located on the self-locking hole 25 of the upper base 21, for fixing the hook 30.

[0056] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0057] The measuring device provided in this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
