DETAILED DESCRIPTION

[0030] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0031] Embodiment 1

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the zipper slider of the present application comprises:

[0033] Slider base 100;

[0034] Pull tab 200;

[0035] A rotating assembly, wherein the lower end of the rotating assembly is connected to the upper surface of the slider base, and the upper end of the rotating assembly is connected to the pull tab;

[0036] The rotating assembly is used to drive the pull tab 200 to rotate around the rotating assembly on the upper surface and above the slider base 100 .

[0037] The zipper puller of the present application includes a puller base, a pull tab and a rotating assembly, wherein the lower end of the rotating assembly is connected to the upper surface of the puller base, and the upper end of the rotating assembly is connected to the pull tab. Due to the existence of the rotating assembly, the rotating assembly can drive the pull tab to rotate on the upper surface and above the puller base with the rotating assembly as the center. In this way, the pull tab can rotate around the rotating assembly. The zipper puller of the present application has a pull tab that can rotate, and the movement mode is flexible. Moreover, the rotation is a novel movement mode in the field of zipper pullers, and is unique.

[0038] In practice, the rotating assembly is specifically used to drive the pull tab to rotate at any angle in both clockwise and counterclockwise directions.

[0039] In this way, the pull tab can rotate in both clockwise and counterclockwise directions at any angle. That is, the pull tab can rotate in both clockwise and counterclockwise directions, and the rotation angle can be any angle, which can be a 360-degree circular rotation. The pull tab has flexible rotation methods, innovative content, and is more entertaining, ornamental, and experiential.

[0040] In implementation, the rotating assembly is also used to drive the open end of the pull tab to rotate to a preset angle in a direction away from the initial position of the pull tab with the rotating assembly as the rotation axis;

[0041] The initial position of the pull tab is the position where the pull tab is located above the slider base when the pull tab is not acted upon by an external force.

[0042] The rotating assembly can not only drive the pull tab to rotate on the upper surface and above the slider base, but also drive the open end of the pull tab to rotate at a preset angle with the rotating assembly as the rotation axis. In this way, the movement of the pull tab is diverse, innovative, entertaining, and enjoyable.

[0043] Specifically, the preset rotation angle is any angle between 90 degrees and 180 degrees.

[0044] Embodiment 2

[0045] The zipper slider of the present application, based on the first embodiment, also has the following features.

[0046] The structure of the rotating assembly has the following structure.

[0047] In implementation, such as Figure 5 and Figure 6 As shown, the rotating assembly includes:

[0048] The mounting shaft 311 is vertically fixed on the upper surface of the slider base 100;

[0049] The bearing 312 has an inner ring which is sleeved on the outer circumference of the mounting shaft 311 and has an interference fit with the mounting shaft 311;

[0050] The mounting ring 313 is sleeved on the outer circumferential surface of the outer ring of the bearing 312, and the fitting between the mounting ring 313 and the outer ring of the bearing 312 is an interference fit;

[0051] The pull tab 200 is connected to the mounting ring 313 , and the mounting ring 313 and the outer ring of the bearing 312 can drive the pull tab 200 to rotate in clockwise and counterclockwise directions at any angle around the inner ring of the bearing 312 and the mounting shaft 311 .

[0052] The mounting shaft and the inner ring of the bearing are fixed as one and are immovable; the mounting collar and the outer ring of the bearing are fixed as one and can rotate at any angle in both clockwise and counterclockwise directions relative to the inner ring of the bearing and the mounting shaft. Because the pull tab is connected to the mounting collar, the pull tab can also rotate at any angle in both clockwise and counterclockwise directions with the inner ring of the bearing and the mounting shaft as the center. The rotating assembly realizes the pull tab to rotate at any angle in both clockwise and counterclockwise directions through a simple structure. The structure is simple and compact, and easy to implement.

[0053] In implementation, such as Figure 5 and Figure 6 As shown, the mounting collar 313 has two mounting collar axial holes arranged opposite to each other;

[0054] The end of the pull tab opposite to the open end has a pull tab avoidance gap, and the two ends of the pull tab avoidance gap are respectively the pull tab installation arms 210 of the pull tab, and the pull tab installation arm 210 has a pull tab installation arm shaft hole;

[0055] The rotating assembly also includes a pull tab first assembly shaft 314;

[0056] Among them, the first assembly axis 314 of the pull tab passes through the axis hole of the pull tab mounting arm and the axis hole of the mounting ring, the first assembly axis 314 of the pull tab is fixed to the mounting ring 313, and there is a clearance fit between the first assembly axis 314 of the pull tab and the axis hole of the pull tab mounting arm so that the pull tab 200 can rotate on the upper surface of the slider base with the first assembly axis 314 of the pull tab as the rotation axis.

[0057] In this way, the open end of the pull tab can rotate on the upper surface of the slider base with the first assembly axis of the pull tab as the rotation axis.

[0058] In implementation, such as Figure 1 As shown, the rotating assembly also includes:

[0059] The built-in top cover 315-1 includes a built-in top cover cover plate and a built-in top cover side wall 315-12 connected below the built-in top cover cover plate, the built-in top cover cover plate covers the upper surface of the mounting collar 313, and the built-in top cover side wall 315-12 covers the side of the mounting collar 313; the built-in top cover side wall 315-12 has two oppositely arranged built-in top cover shaft holes; the built-in top cover side wall is annular or semi-annular;

[0060] The built-in top cover side wall 315-12 is located between the mounting ring 313 and the pull-tab mounting arm 210, and the pull-tab first assembly axis 314 passes through the pull-tab mounting arm axis hole, the built-in top cover axis hole and the mounting ring axis hole in sequence, so that the open end of the pull tab is rotated to 180 degrees in the direction away from the initial position of the pull tab with the pull-tab first assembly axis as the rotation axis.

[0061] In this way, the pull tab can be turned upside down.

[0062] As an alternative, Figure 2 , Figure 5 and Figure 6 As shown, the rotating assembly also includes:

[0063] The external top cover 315-2 includes an external top cover cover plate and a semi-circular external top cover side wall 315-22 connected below the external top cover cover plate. The external top cover cover plate covers the upper surface of the mounting ring 313, and the external top cover side wall 315-22 covers the outer side of the pull-tab mounting arm 210; the external top cover side wall 315-22 has two external top cover shaft holes arranged opposite to each other;

[0064] The external top cover side wall 315-22 is located on the outside of the mounting ring 313 and the pull-tab mounting arm 210, and the pull-tab first assembly axis 314 passes through the external top cover axis hole, the pull-tab mounting arm axis hole and the mounting ring axis hole in sequence, so that the open end of the pull tab is rotated to a preset angle in the direction away from the initial position of the pull tab with the pull-tab first assembly axis 314 as the rotation axis.

[0065] In this way, the pull tab can be lifted upward to a preset angle.

[0066] The semi-circular external cover side wall covers the connection between the pull tab mounting arm and the mounting collar, and the notch formed by the semi-circular external cover side wall is used for the pull tab to extend. In this way, the first assembly axis of the pull tab is basically surrounded by the external cover, and the overall structure of the zipper slider is more compact and more beautiful.

[0067] In implementation, such as Figure 5 and Figure 6 As shown, the top cover has a top cover through hole 315-3, and the slider base 100 has a first locking through hole 110; the top cover includes a built-in top cover or an external top cover;

[0068] The zipper slider also includes a slider first locking assembly with a self-resetting function; the slider first locking assembly is installed between the slider base 100 and the top cover, and the upper end of the slider first locking assembly is exposed from the through hole of the top cover;

[0069] Among them, when the first locking assembly of the slider is subjected to the downward pressure and twisting force at its upper end, the lower end of the slider assembly extends from the first locking through hole 110 into the zipper matched with the zipper slider and gets stuck, thereby preventing the zipper slider from being pulled along the zipper, and the first locking assembly of the slider is locked in the vertical direction; when the first locking assembly of the slider is subjected to the downward pressure and twisting force at its upper end, the lower end of the first locking assembly of the slider is reset, and the first locking assembly of the slider is unlocked in the vertical direction.

[0070] In this way, by pressing and twisting the upper end of the first locking assembly of the slider protruding from the through hole of the top cover, it is possible to prevent the zipper slider from being pulled along the zipper; pressing and twisting again can reset the first locking assembly of the slider.

[0071] By pressing down the upper end of the first locking assembly of the slider, the slider for the zipper can be prevented from being pulled along the zipper, that is, the slider for the zipper can be locked; at the same time, by applying a twisting force to the upper end of the first locking assembly of the slider, the first locking assembly of the slider can be locked in the vertical direction, that is, the slider for the zipper can be prevented from being pulled along the zipper. Pressing and twisting again can reset the first locking assembly of the slider. The locking and resetting method is simple and easy to operate.

[0072] In implementation, such as Figure 5 and Figure 6 As shown, the installation shaft 311 is a hollow installation shaft, and the first locking through hole 110 is provided on the upper surface of the slider base 100 and is located in the hollow part of the installation shaft 311;

[0073] The top cover through hole is located at the center of the cover plate of the top cover.

[0074] In this way, the rotating assembly and the first locking assembly of the slider are not two completely separate components, but are cross-arranged, which is beneficial to improving the utilization of space and making the structure of the zipper slider more compact.

[0075] In implementation, such as Figure 5 and Figure 6 As shown, there are two first locking through holes 110, and the mounting shaft 311 is a mounting shaft with a notch;

[0076] like Figure 5 and Figure 6 As shown, the first locking assembly of the slider includes:

[0077] A first return spring 321 is fixed on the upper surface of the slider base and is located between the two first locking through holes 110;

[0078] An inverted V-shaped locking head 322, the connection of which is pressed onto the first return spring 321, and the long arm 322-1 of the locking head is downwardly disposed opposite to the two first locking through holes 110;

[0079] The locking buckle 323, the first locking column has a horizontal locking ring 323-1 and a locking plate 323-2 extending downward, and the locking plate 323-2 has an L-shaped locking hole 323-21; the locking buckle 323 is fixed to the installation shaft 311, the locking ring 323-1 is located on the upper surface of the installation shaft 311, and the locking plate 323-2 extends into the notch of the installation shaft 311;

[0080] A first locking column 324, the first locking column 324 includes a columnar body and a locking transverse hook 324-1 formed at the bottom end of the columnar body;

[0081] The upper end of the first locking column 324 passes through the locking ring 323-1 and the top cover through hole 315-3, protrudes from the top cover through hole 315-3, and the locking transverse hook 324-1 is located in the vertical part of the L-shaped locking hole 323-21, and the bottom end of the locking transverse hook 324-1 presses against the upper surface of the locking head.

[0082] The locking process is as follows:

[0083] First, the upper end of the first locking column 324 is pressed down, and a twisting force is applied to drive the locking transverse hook 324-1 at the bottom end of the first locking column 324 to move downward along the vertical hole of the L-shaped locking hole. During this process, the bottom end of the locking transverse hook 324-1 keeps against the upper surface of the locking head 322, pressing the locking head 322 to move downward, the first return spring 321 is compressed, and the long arm of the locking head 322 passes through the first locking through hole 110 and extends into the zipper that cooperates with the zipper pull head to get stuck;

[0084] Then, the locking transverse hook 324-1 moves down to the bottom of the L-shaped locking hole, and the locking transverse hook 324-1 slides into the transverse hole of the L-shaped locking hole, and the entire first locking column 324 maintains this position, that is, the zipper slider remains in a locked state.

[0085] The process of achieving unlocking is as follows:

[0086] First, the upper end of the first locking column applies a reverse twisting force, and the locking transverse hook leaves the transverse hole of the L-shaped locking hole and enters the vertical hole of the L-shaped locking hole. Due to the reset action of the first reset spring, the first locking column is automatically driven to move upward, so that the long arm of the locking head exits the first locking through hole, and the zipper pull head can be pulled along the zipper.

[0087] In implementation, such as Figure 5 and Figure 6 As shown, the first locking assembly of the slider also includes:

[0088] The first return spring positioning blind hole 120 is arranged on the upper surface of the slider base 100 and is located in the hollow part of the mounting shaft; the first locking through holes 110 are two and symmetrically arranged on both sides of the first return spring positioning blind hole 120;

[0089] The lower end of the first return spring 321 is fixed in the first return spring positioning blind hole 120 .

[0090] The existence of the first return spring positioning blind hole facilitates the positioning of the first return spring during installation.

[0091] In implementation, such as Figure 2 and Figure 5 As shown, the upper end of the cylindrical body has a locking button 324-2, the locking button 324-2 protrudes from the top cover through hole, and the radial dimension of the locking button is larger than the radial dimension of the cylindrical body.

[0092] The radial dimension of the locking button is larger than the radial dimension of the cylindrical body, which is convenient for users to perform locking and unlocking operations. It is entertaining, ornamental and experiential, with a novel appearance and a smooth feel.

[0093] It provides users with a zipper that is both noble and fun, especially for those who like to pursue differentiated fashion.

[0094] It also meets the market demand for today's fashion products, and the research and development of matching zippers is more unique.

[0095] Embodiment 3

[0096] The zipper slider of the present application, based on the first embodiment, also has the following characteristics.

[0097] like Figure 3 , Figure 4 and Figure 7 As shown, the rotating assembly includes:

[0098] The base column 411 is vertically fixed on the upper surface of the slider base 100;

[0099] A rotating ring 412 is sleeved on the outer circumference of the base column 411 and can rotate around the base column 411;

[0100] The pull tab 200 is connected to the rotating ring 412 .

[0101] The base column is fixed on the upper surface of the slider base and is immovable. The rotating ring is sleeved on the outer peripheral surface of the base column 411 and can rotate around the base column at any angle in both clockwise and counterclockwise directions. Because the pull tab is connected to the rotating ring, the pull tab can also rotate at any angle in both clockwise and counterclockwise directions with the base column as the center. The rotating component realizes the rotation of the pull tab at any angle in both clockwise and counterclockwise directions through a simple structure. The structure is simple and compact, and easy to implement.

[0102] In implementation, such as Figure 3 , Figure 4 and Figure 7 As shown, the base column 411 has an annular groove 411-1, and the rotating ring 412 has a rotating ring shaft hole arranged oppositely;

[0103] The end of the pull tab opposite to the open end has a pull tab avoidance gap, and the two ends of the pull tab avoidance gap are pull tab mounting arms 210 respectively, and the pull tab mounting arm 210 has a pull tab mounting arm shaft hole;

[0104] The rotating assembly also includes a pull-tab second assembly shaft 413;

[0105] Among them, the second assembly axis 413 of the pull tab passes through the axis hole of the pull tab mounting arm and the axis hole of the rotating ring. The second assembly axis 413 of the pull tab is fixed to the rotating ring 412 and the second assembly axis 413 of the pull tab extends into the annular groove 411-1. There is a clearance fit between the second assembly axis 413 of the pull tab and the axis hole of the pull tab mounting arm, so that the pull tab 200 can rotate on the upper surface of the slider base 100 with the second assembly axis 413 of the pull tab as the rotating axis.

[0106] In this way, the open end of the pull tab can rotate on the upper surface of the slider base with the second assembly axis of the pull tab as the rotation axis.

[0107] During implementation, the rotating assembly further includes:

[0108] The first upper cover comprises a first upper cover plate and a first upper cover side wall connected to the first upper cover plate, the first upper cover plate covers the upper surface of the rotating ring, and the first upper cover side wall covers the side of the rotating ring; the first upper cover side wall has two first upper cover shaft holes arranged oppositely; the first upper cover side wall is annular or semi-annular;

[0109] The first upper cover side wall is located between the pull-tab mounting arm and the rotating ring, and the second assembly axis of the pull-tab passes through the pull-tab mounting arm axis hole, the second upper cover axis hole and the rotating ring axis hole in sequence, so that the open end of the pull-tab is rotated to 180 degrees in the direction away from the initial position of the pull-tab with the second assembly axis of the pull-tab as the rotation axis.

[0110] In this way, the pull tab can be turned upside down.

[0111] As an alternative, Figure 3 , Figure 4 and Figure 7 As shown, the rotating assembly also includes:

[0112] The second upper cover 414 includes a second upper cover plate and a semi-circular second upper cover side wall 414-1 connected below the second upper cover plate. The second upper cover plate covers the upper surface of the rotating ring 412, and the second upper cover side wall 414-1 covers the connection between the pull-tab mounting arm 210 and the rotating ring 412; the second upper cover side wall 414-1 has two second upper cover shaft holes arranged opposite to each other;

[0113] The second upper cover side wall 414-1 is located on the outside of the rotating ring 412 and the pull-tab mounting arm 210, and the pull-tab second assembly axis 413 passes through the second upper cover axis hole, the pull-tab mounting arm axis hole and the rotating ring axis hole in sequence, so that the open end of the pull tab is rotated to a preset angle in the direction away from the initial position of the pull tab with the pull-tab second assembly axis 413 as the rotation axis.

[0114] The preset angle at which the open end of the pull tab rotates in a direction away from the initial position of the pull tab with the second assembly axis of the pull tab as the rotation axis is any angle between 90 degrees and 180 degrees.

[0115] In this way, the pull tab can be lifted upward to a preset angle.

[0116] The semi-circular second upper cover side wall, on the one hand, covers the connection between the pull-tab mounting arm and the rotating ring, and on the other hand, the notch formed by the semi-circular second upper cover side wall is used for the pull-tab to extend out. In this way, the second assembly axis of the pull-tab is basically surrounded by the second upper cover, and the overall structure of the zipper slider is more compact and more beautiful.

[0117] In implementation, such as Figure 3 , Figure 4 and Figure 7 As shown, the upper cover has an upper cover through hole 414-2, and the slider base has a second locking through hole 130; the upper cover includes a first upper cover or a second upper cover;

[0118] The zipper slider also includes a slider second locking assembly with a self-resetting function; the slider second locking assembly is installed between the slider base and the upper cover, and the upper end of the slider second locking assembly is exposed from the through hole 414-2 of the upper cover;

[0119] Among them, when the second locking assembly of the slider is pressed downward at its upper end and the pull tab 200 rotates to a preset vertical locking position, the lower end of the second locking assembly of the slider extends from the second locking through hole 130 into the zipper that cooperates with the zipper slider and gets stuck, thereby preventing the zipper slider from being pulled along the zipper, and the second locking assembly of the slider is locked in the vertical direction; when the pull tab 200 rotates away from the preset vertical locking position, the lower end of the second locking assembly of the slider is reset, and the second locking assembly of the slider is unlocked in the vertical direction.

[0120] The second locking assembly of the slider with a self-resetting function, when locking the slider, applies a downward pressure to the upper end of the second locking assembly of the slider to prevent the slider from being pulled along the zipper; by rotating the pull tab to a preset vertical locking position, the second locking assembly is locked in the vertical direction, that is, the slider is prevented from being pulled along the zipper. When the pull tab of the second locking assembly of the slider rotates away from the preset vertical locking position, the locking in the vertical direction is released, and the lower end of the second locking assembly of the slider is reset.

[0121] In implementation, such as Figure 7 As shown, the base column 411 is a hollow base column, and the second locking through hole 130 is provided on the upper surface of the slider base and is located in the hollow part of the base column 411;

[0122] The upper cover through hole 414 - 2 is located at the center of the cover plate of the upper cover.

[0123] In this way, the rotating assembly and the second locking assembly of the slider are not two completely separate components, but are cross-arranged, which is beneficial to improving the utilization of space and making the structure of the zipper slider more compact.

[0124] In implementation, such as Figure 7 As shown, the second locking assembly of the slider includes:

[0125] The locking seat 421 is located in the hollow part of the base column 411 and is fixed to the inner top of the upper cover. The locking seat 421 has a locking seat through hole 421-1 that runs through the upper and lower parts, and a transverse positioning groove 421-2 is provided on the side of the locking seat 421;

[0126] A second locking column 422 and a second return spring 423; a locking protrusion 422-1 is convexly provided at the lower end of the second locking column 422, and a transverse expansion head 422-2 is provided on the side of the second locking column;

[0127] The upper end of the second locking column 422 passes through the locking seat through hole 421-1 and the upper cover through hole 414-2 to press the second return spring 423 onto the upper surface of the slider base 100, and the locking protrusion 422-1 is located above the locking seat through hole 421-1;

[0128] Among them, when the upper end of the second locking column 422 is subjected to a downward pressure force, the locking protrusion 422-1 extends from the locking seat through hole 421-1 into the zipper where the zipper slider cooperates and gets stuck, thereby preventing the zipper slider from being pulled along the zipper; the pull tab 200 is rotated to drive the upper cover and the locking seat 421 to rotate together, and the second locking column 422 does not move. When the transverse positioning groove 421-2 rotates to the outside of the transverse expansion head 422-2, the transverse expansion head 422-2 extends into the transverse positioning groove 421-2 to prevent the second locking column 422 from resetting upward; that is, the transverse positioning groove serves as a preset vertical locking position.
