Description

Technical Field

[0001] This application belongs to the field of communication technology, and more specifically, relates to a thin and light zipper pull, a double-opening zipper, and zipper products. Background Technology

[0002] A double-opening zipper is a zipper design with two independent slider heads. The two heads can slide independently without interfering with each other, allowing the user to pull both heads simultaneously or operate either one individually. However, a problem with related double-opening zippers is that the overall thickness of the two slider heads is relatively large when they touch. Utility Model Content

[0003] The purpose of this application is to provide a thin and light zipper pull, a double-opening zipper, and a zipper product to solve the technical problem in the prior art where the overall thickness of the two zipper pulls is large after they abut against each other.

[0004] Firstly, embodiments of this application provide a thin and light zipper puller.

[0005] The slim zipper pull provided in this application embodiment includes a body for moving relative to a chain belt along a first direction. The body includes a first outer wing plate, a first mechanism, and a first inner wing plate. The first outer wing plate and the first inner wing plate are arranged parallel to each other and spaced apart. The first mechanism is connected between the first outer wing plate and the first inner wing plate. A crossbar is provided at the end of the first outer wing plate in the first direction. The crossbar is spaced apart from the first outer wing plate and extends along a second direction, which is orthogonal to the first direction. A first pull tab is provided, at least a portion of which is arranged around the crossbar. The first pull tab is used to pull the body.

[0006] The beneficial effects of the thin and light zipper pull provided in this application embodiment are as follows: Compared with the prior art, the crossbar of the thin and light zipper pull provided in this application embodiment is located on one side of the first outer wing plate in the first direction. When the pull tab installed on the crossbar is parallel to the first outer wing plate, the pull tab is prevented from protruding from the first outer wing plate in the thickness direction of the zipper pull, thereby reducing the thickness dimension of the thin and light zipper pull provided in this application embodiment in the arrangement direction of the first outer wing plate and the first inner wing plate, so that the thin and light zipper pull provided in this application embodiment has the advantage of smaller thickness.

[0007] Optionally, the surface of the crossbar is provided with at least one groove, and at least a portion of the first pull tab corresponds to the groove;

[0008] The sinkhole is located on the side of the crossbar away from the first outer wing plate in the first direction;

[0009] And / or, the sinkhole is located on at least one side of the crossbar in a third direction, the third direction being orthogonal to the first direction and the third direction being orthogonal to the second direction.

[0010] Optionally, the distance between the sinkhole and one end of the crossbar in the second direction is the same as the distance between the sinkhole and the other end of the crossbar in the second direction.

[0011] Optionally, the first pull tab includes a handle portion and a first annular portion, the first annular portion being connected to the end of the handle portion, the first annular portion being arranged around the crossbar, and the first annular portion fitting into the sink groove.

[0012] Optionally, the crossbar is connected to two connecting portions at both ends along the second direction, and the connecting portions are connected to the first outer wing plate; the first pull tab includes a second annular portion, the second annular portion is sleeved on the outer periphery of the crossbar, and the two ends of the second annular portion in the second direction respectively abut against the two connecting portions.

[0013] Secondly, embodiments of this application provide a double-opening zipper.

[0014] The double-opening zipper provided in this application embodiment includes a first zipper belt, a second zipper belt, a first zipper head, and a second zipper head. Both the first zipper head and the second zipper head can be slidably mounted on the first zipper belt and the second zipper belt. At least one of the first zipper head and the second zipper head is the thin zipper head described in any of the above embodiments.

[0015] The beneficial effects of the double-opening zipper provided in this application embodiment are that, compared with the prior art, at least one of the two zipper pulls provided in this application embodiment includes a thin zipper pull provided in this application embodiment. On the one hand, when both the first and second zipper pulls of the double-opening zipper provided in this application embodiment are thin zipper pulls provided in this application embodiment, the thin zipper pulls provided in this application embodiment have the advantage of smaller thickness, thereby reducing the overall thickness of the first and second zipper pulls when they abut against each other. On the other hand, when the first zipper pull of the double-opening zipper provided in this application embodiment is a thin zipper pull, the pull tab of the second zipper pull can rest against the first outer wing plate of the first zipper pull, thereby preventing the first zipper pull from lifting the pull tab of the second zipper pull, and reducing the overall thickness of the first and second zipper pulls when they abut against each other.

[0016] In summary, the double-opening zipper provided in this application has the advantage that the overall thickness of the two zipper heads is relatively small after they abut against each other.

[0017] Optionally, the first zipper head is the thin zipper head described in any of the above embodiments, and the second zipper head includes a second zipper tab, a second outer wing plate, a second mechanism, and a second inner wing plate. The second outer wing plate and the second inner wing plate are arranged parallel to each other and spaced apart. The second mechanism is connected between the second outer wing plate and the second inner wing plate. The second outer wing plate is provided with a hinge seat on the side away from the second inner wing plate, and the second zipper tab is rotatably mounted on the hinge seat.

[0018] When the first pull head and the second pull head come into contact, a portion of the second pull tab can be located on the side of the first outer wing plate away from the first inner wing plate, and the second pull tab can be parallel to the first outer wing plate.

[0019] Optionally, the second pull tab includes a protrusion that protrudes toward the first outer wing plate when a portion of the second pull tab is located on the side of the first outer wing plate away from the first inner wing plate;

[0020] At least a portion of the protrusion is located between the crossbar and the first outer wing plate.

[0021] Optionally, one of the first zipper and the second zipper may be provided with a mounting groove, and the other of the first zipper and the second zipper may be provided with a mounting part, which can be fitted into the mounting groove.

[0022] Thirdly, this application provides a zipper product.

[0023] The zipper products provided in this application include the double-opening zipper described in the above embodiments.

[0024] It is understandable that the beneficial effects of the third aspect mentioned above can be found in the relevant descriptions in the second aspect above, and will not be repeated here. Attached Figure Description

[0039] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0040] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0041] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] A double-opening zipper is a zipper design with two independent zipper pulls. The two zipper pulls can slide independently without interfering with each other. Users can pull both zipper pulls at the same time or operate either of the two zipper pulls individually.

[0044] However, in the related technology, after the two zipper pulls of a double zipper come into contact, the tab of one of the zipper pulls rests on the other of the two zipper pulls, such as... Figure 1 As shown, the pull tab of one of the two zipper heads is lifted up, which causes the double-opening zipper in the related technology to have a problem where the overall thickness of the combined body of the two zipper heads is large when the two zipper heads are pressed together.

[0045] To address the aforementioned technical problems, embodiments of this application provide a thin and light zipper pull, a double-opening zipper using the thin and light zipper pull, and a zipper product using the double-opening zipper. The zipper product provided in this application embodiment can be clothing, backpacks, handbags, or other items containing double-opening zippers.

[0046] Please refer to the following: Figures 2 to 5 The thin and light zipper puller 100a provided in the embodiments of this application will now be described.

[0047] It should be noted that the first direction in the following text is the x-direction shown in the figure, the second direction in the following text is the y-direction shown in the figure, and the third direction in the following text is the z-direction shown in the figure.

[0048] The thin and light zipper puller 100a provided in this application embodiment includes a body 101 and a first zipper tab 102.

[0049] The body 101 is used to move relative to the chain belt along a first direction x. The body 101 includes a first outer wing plate 110, a first mechanism 130 and a first inner wing plate 120. The first outer wing plate 110 and the first inner wing plate 120 are arranged parallel to each other and spaced apart. The first mechanism 130 is connected between the first outer wing plate 110 and the first inner wing plate 120. The first outer wing plate 110 has a crossbar 140 at its end in the first direction x. The crossbar 140 is arranged spaced apart from the first outer wing plate 110. The crossbar 140 extends along a second direction y, which is orthogonal to the first direction x.

[0050] like Figure 1 As shown, both the first outer wing plate 110 and the first inner wing plate 120 are parallel to... Figure 1 As shown in the xOy plane extension, the first outer wing plate 110 and the first inner wing plate 120 are arranged at intervals along the third direction z. The first mechanism 130 is connected between the end of the first outer wing plate 110 in the first direction x and the end of the first inner wing plate 120 in the first direction x. The first mechanism 130 divides the space between the first outer wing plate 110 and the first inner wing plate 120 to form a Y-shaped first channel. When the body 101 moves relative to the two parallel chain belts in the first direction x, the chain teeth on the two parallel and spaced chain belts mesh with each other in the first channel, or the chain teeth on the two meshing chain belts disengage from each other in the first channel, thereby changing the opening and closing state of the chain belts by the movement of the body 101 relative to the chain belts.

[0051] like Figures 3 to 5 As shown, the crossbar 140 is located on one side of the first outer wing plate 110 in the first direction x. The crossbar 140 extends along the second direction y. The crossbar 140 is used to connect the first pull tab 102 to the first outer wing plate 110. At least part of the first pull tab 102 is arranged around the crossbar 140. The first pull tab 102 is used to pull the body 101.

[0052] The beneficial effects of the thin and light zipper pull 100a provided in this application embodiment are as follows: Compared with the prior art, the crossbar 140 of the thin and light zipper pull 100a provided in this application embodiment is disposed on one side of the first outer wing plate 110 in the first direction x. When the pull tab installed on the crossbar 140 is parallel to the first outer wing plate 110, the pull tab is prevented from protruding from the first outer wing plate 110 in the thickness direction of the zipper pull, thereby reducing the thickness dimension of the thin and light zipper pull 100a provided in this application embodiment in the arrangement direction of the first outer wing plate 110 and the first inner wing plate 120, so that the thin and light zipper pull 100a provided in this application embodiment has the advantage of smaller thickness.

[0053] In some embodiments provided in this application, such as Figure 2As shown, the surface of the first outer wing plate 110 facing away from the second outer wing plate 210 has a recess 111. Thus, on the one hand, the recess 111 prevents the user's fingers from sliding relative to the body 101 when the user's fingers pinch the body 101, and on the other hand, the recess 111 further reduces the average thickness of the first outer wing plate 110.

[0054] In some embodiments, the first mechanism 130 is connected to one end of the first outer wing plate 110 in the first direction x, and the crossbar 140 is disposed on the other side of the first outer wing plate 110 in the first direction x.

[0055] In other embodiments, the first mechanism 130 and the crossbar 140 are located on the same side of the first outer wing plate 110 in the first direction x.

[0056] In some embodiments provided in this application, the surface of the crossbar 140 is provided with at least one groove 141, and at least a portion of the first pull tab 102 corresponds to the groove 141;

[0057] The sink 141 is located on the side of the crossbar 140 away from the first outer wing plate 110 in the first direction x;

[0058] And / or, the settling trough 141 is provided on at least one side of the crossbar 140 in the third direction z, which is orthogonal to the first direction x and the third direction z is orthogonal to the second direction y.

[0059] In some embodiments, such as Figure 4 As shown, at least part of the first pull tab 102 is engaged between the inner walls of the two sides of the sink 141 in the second direction y.

[0060] In other embodiments, such as Figure 5 As shown, at least a portion of the first pull tab 102 is located at the opening of the sink 141.

[0061] In some embodiments, such as Figure 2 and Figure 3 As shown, a portion of the sinkhole 141 is located on the side of the crossbar 140 away from the first outer wing plate 110 in the first direction x, and a portion of the sinkhole 141 is located on both sides of the crossbar 140 in the third direction z.

[0062] In other embodiments (not shown in the figures), a portion of the sinkhole 141 is located on one side of the crossbar 140 in the first direction x, and a portion of the sinkhole 141 is located on the side of the crossbar 140 away from the first inner wing plate 120 in the third direction z.

[0063] In other embodiments (not shown in the figures), a portion of the sinkhole 141 is located on one side of the crossbar 140 in the first direction x, and a portion of the sinkhole 141 is located on the side of the crossbar 140 in the third direction z facing the first inner wing plate 120.

[0064] In another embodiment (not shown in the figure), the sink 141 is located entirely on the side of the crossbar 140 away from the first outer wing plate 110 in the first direction x.

[0065] In other embodiments (not shown in the figures), the sink 141 is located entirely on the side of the crossbar 140 away from the first inner wing plate 120 in the third direction z.

[0066] In other embodiments (not shown in the figures), the sink 141 is located entirely on the side of the crossbar 140 in the third direction z, near the first inner wing plate 120.

[0067] Therefore, on the one hand, the radial dimension of the crossbar 140 at the bottom of the sink 141 is smaller than the radial dimension at other positions, and the first pull tab 102 can be snapped into the sink 141, and the position of the first pull tab 102 in the second direction y is restricted by the two inner walls of the sink 141 in the second direction y; on the other hand, the sink 141 is not set on the side of the crossbar 140 facing the first outer wing plate 110 in the first direction x, so that the surface of the crossbar 140 facing the first outer wing plate 110 in the first direction x remains flat. When the width dimension of the first pull tab 102 in the second direction y is greater than the width dimension of the sink 141 in the second direction y, the first pull tab 102 can remain flat when it overlaps the surface of the crossbar 140 facing the first outer wing plate 110 in the first direction x.

[0068] In some embodiments, such as Figure 2 and Figure 3 As shown, there is a single settling tank 141.

[0069] In other embodiments (not shown in the figures), there are multiple sinks 141, which are arranged at intervals along the second direction y.

[0070] In other embodiments (not shown in the figures), there are multiple sinks 141, which are arranged at circumferential intervals along the crossbar 140.

[0071] In some embodiments provided in this application, the distance between the sink 141 and one end of the crossbar 140 in the second direction y is the same as the distance between the sink 141 and the other end of the crossbar 140 in the second direction y.

[0072] like Figure 2 and Figure 3 As shown, there is one sink 141, which is located in the middle section of the crossbar 140 in the second direction y. Thus, when the first pull tab 102 is fastened in the sink 141 by the buckle, the central axis of the first pull tab 102 in the second direction y coincides with the central axis of the body 101 in the second direction y.

[0073] Therefore, when the first pull tab 102 is pulled in the first direction x, the connection position between the first pull tab 102 and the body 101 is located on the axis of the body 101 moving in the first direction x, so that the force on the body 101 is also along the first direction x, and the body 101 is prevented from shifting in the second direction y due to uneven force.

[0074] In some embodiments provided in this application, the first pull tab 102 includes a handle portion 150 and a first annular portion 160. The first annular portion 160 is connected to the end of the handle portion 150, the first annular portion 160 is arranged around the crossbar 140, and the first annular portion 160 fits into the sink 141.

[0075] like Figure 4 As shown, the first pull tab 102 is a clip pull tab, with the annular portion arranged around the crossbar 140. The handle portion 150 extends radially along the first annular portion 160. The handle portion 150 is thin and the thickness of the middle part of the handle portion 150 is smaller than the thickness of the edge of the handle portion 150, so as to facilitate the user's fingers to hold the handle portion 150.

[0076] Therefore, when the first annular portion 160 is rotatably assembled into the groove 141 of the horizontal bar 140, the handle portion 150 extends radially along the horizontal bar 140. When the first direction x is vertical, the handle portion 150 can extend along the first direction x under the action of gravity, thereby reducing the thickness of the thin and light zipper pull head 100a provided in this application embodiment.

[0077] In some embodiments, the first annular portion 160 is made of a hard material such as PVC, plastic, stainless steel, or metal.

[0078] In other embodiments, the first annular portion 160 is made of a flexible material such as fabric or rubber.

[0079] In some embodiments, the first annular portion 160 and the handheld portion 150 are made of the same material and are integrally formed.

[0080] In other embodiments, the first annular portion 160 and the handheld portion 150 are made of different materials.

[0081] In some embodiments provided in this application, the first annular portion 160 includes a notch 161 that extends radially through the first annular portion 160 and connects the through hole and the outer wall of the first annular portion 160. The notch 161 is located at one end of the first annular portion 160 away from the handheld portion 150.

[0082] Therefore, when the first annular portion 160 is made of a rigid material, the crossbar 140 can be engaged with the first annular portion 160 on the outer periphery of the crossbar 140 through the notch 161161.

[0083] In some embodiments provided in this application, the first pull tab 102 includes a second annular portion 170, which is sleeved on the outer periphery of the crossbar 140, and both ends of the crossbar 140 in the second direction y are located inside the second annular portion 170.

[0084] like Figure 5 As shown, the first pull tab 102 is a fabric strip or a leather piece. The end of the first pull tab 102 is wound around the second direction y to form a second annular portion 170. The second annular portion 170 can be sleeved on the outer periphery of the crossbar 140, and the inner wall of the second annular portion 170 can abut against the side of the crossbar 140 facing the first outer wing plate 110. Since the groove 141 is located on the side of the crossbar 140 away from the first outer wing plate 110 or the groove 141 is located on both sides of the crossbar 140 in the third direction z, the side of the crossbar 140 facing the first outer wing plate 110 is flat, thereby keeping the end of the leather piece or the first pull tab 102 without material flat, improving the appearance and optimizing the user experience.

[0085] In some embodiments, the crossbar 140 is provided with a connecting portion 142 on both sides in the second direction y. The connecting portion 142 extends along the first direction x. One end of the connecting portion 142 is connected to the first outer wing plate 110, and the other end of the connecting portion 142 is connected to one end of the crossbar 142 in the second direction y.

[0086] Thus, the crossbar 140, the first outer wing plate 110, and the two connecting parts 142 together form a through hole, and part of the second annular part 170 passes through the through hole. The two connecting parts 142 can clamp the two ends of the second annular part 170 in the second direction, thereby fixing the position of the second annular part 170 in the second direction y through the two connecting parts 142, and preventing the first pull tab 102 from moving in the second direction 170.

[0087] The double-opening zipper provided in the embodiments of this application is described below with reference to the accompanying drawings.

[0088] The double-opening zipper provided in this application embodiment includes a first zipper belt (not shown in the figure), a second zipper belt (not shown in the figure), a first zipper pull 100, and a second zipper pull 200.

[0089] Both the first zipper 100 and the second zipper 200 can be slidably mounted on the first chain and the second chain, and at least one of the first zipper 100 and the second zipper 200 is the thin zipper 100a in any of the above embodiments.

[0090] like Figure 6 As shown, both the first chain and the second chain extend along the first direction x, and the first chain and the second chain are arranged opposite each other about the second direction y, and the first chain and the second chain can mesh with each other.

[0091] In some embodiments, both the first zipper pull 100 and the second zipper pull 200 are provided as thin and light zipper pulls 100a in the embodiments of this application.

[0092] In other embodiments, the first zipper pull 100 is the thin and light zipper pull 100a provided in the embodiments of this application, and the second zipper pull 200 is... Figure 6 The structure shown.

[0093] Both the first pull head 100 and the second pull head 200 can be slidably mounted on the first chain and the second chain, and both the first pull head 100 and the second pull head 200 can switch the chain teeth of the first chain (not shown in the figure) and the chain teeth of the second chain (not shown in the figure) between an engaged state and a disengaged state.

[0094] Therefore, as Figure 6 As shown, the second pull tab 230 of the second zipper 200 can overlap the first outer wing plate 110 of the first zipper 100, thereby preventing the second pull tab 230 from being lifted up by the first zipper 100 and reducing the thickness of the combination of the first zipper 100 and the second zipper 200.

[0095] The beneficial effect of the double-opening zipper provided in this application embodiment is that, compared with the prior art, the double-opening zipper provided in this application embodiment includes at least one of the two zipper heads, namely the thin and light zipper head 100a provided in this application embodiment. On the one hand, when both the first zipper head 100 and the second zipper head 200 of the double-opening zipper provided in this application embodiment are thin and light zipper heads 100a provided in this application embodiment, the thin and light zipper head 100a provided in this application embodiment has the advantage of smaller thickness, thereby reducing the impact of the first zipper head 100 and the second zipper head 200 of the double-opening zipper provided in this application embodiment on the thickness of the zipper head 100 and the second zipper head 200. When the zipper pulls 200 abut against each other, the overall thickness of the first zipper pull 100 and the second zipper pull 200 is reduced. On the other hand, when the first zipper pull 100 of the double-opening zipper provided in this application embodiment is a thin zipper provided in this application embodiment, the pull tab of the second zipper pull 200 can rest on the first outer wing plate 110 of the first zipper pull 100, thereby preventing the first zipper pull 100 from lifting the pull tab of the second zipper pull 200 and reducing the overall thickness of the first zipper pull 100 and the second zipper pull 200 when they abut against each other.

[0096] In summary, the double-opening zipper provided in this application has the advantage that the overall thickness of the two zipper heads is relatively small after they abut against each other.

[0097] In some embodiments provided in this application, the first zipper 100 is the thin zipper 100a of any of the above embodiments, and the second zipper 200 includes a second zipper tab 230, a second outer wing plate 210, a second mechanism and a second inner wing plate 220. The second outer wing plate 210 and the second inner wing plate 220 are arranged parallel and spaced apart. The second mechanism is connected between the second outer wing plate 210 and the second inner wing plate 220. The second outer wing plate 210 is provided with a hinge seat 211 on the side away from the second inner wing plate 220. The second zipper tab 230 is rotatably mounted on the hinge seat 211.

[0098] When the first pull head 100 and the second pull head 200 come into contact, a portion of the second pull tab 230 can be located on the side of the first outer wing plate 110 away from the first inner wing plate 120, and the second pull tab 230 can be parallel to the first outer wing plate 110.

[0099] like Figure 6 As shown, by setting the hinge 211, the rotation axis of the second pull tab 230 is located on the side of the second outer wing plate 210 away from the second inner wing plate 220. Thus, when the second pull tab 230 rests on the surface of the first outer wing plate 110, the second pull tab 230 is parallel to the first outer wing plate 110, and the second pull tab 230 is located between the end of the hinge 211 away from the second outer wing plate 210 and the second outer wing plate 210.

[0100] In some embodiments provided in this application, the second pull tab 230 includes a protrusion 231, which protrudes toward the first outer wing plate 110 when a portion of the second pull tab 230 is located on the side of the first outer wing plate 110 away from the first inner wing plate 120.

[0101] At least part of the protrusion 231 is located between the crossbar 140 and the first outer wing plate 110.

[0102] As shown in Figure 7, the second pull tab 230 includes a main body and a protrusion 231. The main body extends radially along the hinge 211 and can rotate relative to the hinge 211. The protrusion 231 is provided on one side in the thickness direction of the main body to prevent the second pull tab 230 from sliding relative to the user's fingers when the user pinches the second pull tab 230.

[0103] The crossbar 140 of the first pull head 100 and the first outer wing plate 110 are arranged at intervals along the first direction x. The protrusion 231 can be fitted into the gap between the crossbar 140 and the first outer wing plate 110, so that the first pull head 100 avoids the protrusion 231, further preventing the second pull tab 230 from being lifted by the first pull head 100 when it rests against the first pull head 100, and reducing the overall thickness of the first pull head 100 and the second pull head 200 when they abut against each other.

[0104] In some embodiments provided in this application, one of the first pull head 100 and the second pull head 200 is provided with an assembly groove 121, and the other of the first pull head 100 and the second pull head 200 may be provided with an assembly part 221, which can be fitted into the assembly groove 121.

[0105] Therefore, when the first zipper pull 100 and the second zipper pull 200 abut against each other, the assembly part 221 can fit into the assembly groove 121, thereby combining the first zipper pull 100 and the second zipper pull 200 to form an integral structure, preventing the first zipper pull 100 and the second zipper pull 200 from deflecting each other, so that the first pull tab 102 and the second pull tab 230 both extend along the first direction x, thereby reducing the size of the combination of the first zipper pull 100 and the second zipper pull 200 in the second direction y, so that the double-opening zipper provided in this application embodiment has the advantage of smaller size.

[0106] In some embodiments, such as Figure 7 As shown, the first inner wing plate 120 has a mounting groove 121 on the side facing the second inner wing plate 220, and the end of the second inner wing plate 220 facing the first inner wing plate 120 can be fitted into the mounting groove 121.

[0107] In some other embodiments (not shown in the figures), the second inner wing plate 220 is provided with a mounting groove 121 on the side facing the first inner wing plate 120, and the end of the first inner wing plate 120 facing the second inner wing plate 220 can be fitted into the mounting groove 121.

[0108] In some other embodiments (not shown in the figures), the first outer wing plate 110 is provided with a mounting groove 121 on the side facing the second outer wing plate 210, and the end of the second outer wing plate 210 facing the first outer wing plate 110 can be fitted into the mounting groove 121.

[0109] In some other embodiments (not shown in the figures), the second outer wing plate 210 is provided with a mounting groove 121 on the side facing the first outer wing plate 110, and the end of the first outer wing plate 110 facing the second outer wing plate 210 can be fitted into the mounting groove 121.

[0110] In some embodiments, as shown in the figure, the mounting groove 121 is provided on the side of the first inner wing plate 120 facing the first outer wing plate 110 in the third direction z, and the opening of the mounting groove 121 faces the first outer wing plate 110. Part of the second inner wing plate 220 can be snapped into the mounting groove 121.

[0111] The zipper products provided in this application are described below.

[0112] The zipper products provided in this application include the double-opening zipper in the above embodiments.

[0113] The double-opening zipper provided in this application embodiment can be any type of toothed zipper, toothed zipper, or injection-molded zipper. The zipper products provided in this application embodiment can be any type of zipper-containing product such as clothing, bags, outdoor equipment, and household goods.

[0114] The double-opening zipper provided in this application embodiment has the advantage that the overall thickness of the two zipper heads is small after they abut against each other, thus making the zipper product provided in this application embodiment aesthetically pleasing after the zipper is closed.

[0115] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
