[0037] It should be noted that, for the convenience of description, only the parts related to the relevant application are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0038] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0039] See also Figure 1-Figure 16 .

[0040] The present application discloses a locking slider of an invisible zipper, comprising a pull tab 1, a slider body 2 and a hook 3. Specifically, the pull tab 1 and the hook 3 are both mounted on the slider body 2, and the pull tab 1 is fixed to the slider body 2 through the hook 3.

[0041] A first cross bar 11 is provided at one end of the pull tab 1, and the first cross bar 11 includes a hinge portion and a protrusion 111 protruding from the outer peripheral surface of the hinge portion; a hinge groove 211 rotatably matched with the hinge portion is provided on the mold nose 21 of the slider body 2, so that the pull tab 1 can rotate on the slider body 2, and a limiting groove 212 is provided on the slider body 2 to limit the position of the protrusion 111. The limiting groove 212 is opened at the bottom of the hinge groove 211, and the protrusion 111 cooperates with the limiting groove 212 to limit the movement of the pull tab 1 along the axial direction of the first cross bar 11 to reduce the shaking of the pull tab 1.

[0042] At least one end of the hook 3 can be inserted into the chain tooth. The hook 3 is inserted into the chain tooth to lock the slider body 2, and the hook 3 is separated from the chain tooth to release the locking of the slider body 2.

[0043] The protrusion 111 has a touch portion, which can push the hook 3 when the pull tab 1 rotates to form a preset angle with the lower surface of the slider body 2, so that the hook 3 is disengaged from the chain teeth and the slider body 2 is unlocked. In this solution, the slider body 2 is switched between the locked state and the unlocked state by rotating the protrusion 111.

[0044] The touch portion of the protrusion 111 is a portion where the protrusion 111 can contact the hook 3 and apply a thrust to the hook 3. When the pull tab 1 rotates to a preset angle with the lower surface of the slider body 2, the touch portion of the protrusion 111 contacts the hook 3 and applies a thrust to the hook 3. When the pull tab 1 continues to rotate beyond the preset angle, the touch portion of the protrusion 111 continues to push the hook 3, so that the hook 3 is disengaged from the chain teeth, and the slider body 2 is unlocked; the pull tab 1 is rotated in the opposite direction until the pull tab 1 returns to the initial position, and the hook 3 is inserted and connected, locking the slider body 2.

[0045] The lower surface of the slider body 2 is the surface of the slider body 2 located on the inner side of the cloth tape, and the inner side of the cloth tape is the side of the cloth tape close to the inside of the garment.

[0046] The preset angle is flexibly designed by technicians in this field according to actual needs and can be 5°, 10° or other angles, which is not limited here.

[0047] The locking slider of the invisible zipper disclosed in the present application comprises a slider 1, a slider body 2 and a hook 3. A hinged portion and a protrusion 111 are provided on the first crossbar 11 of the slider 1, and a hinged groove 211 for rotationally cooperating with the hinged portion and a limiting groove 212 for limiting the protrusion 111 are provided on the mold nose 21 of the slider body 2. The slider 1 is installed on the slider body 2, the hinged portion is located in the hinged groove 211, and the protrusion 111 is located in the limiting groove 212. When the slider 1 rotates, the hinged portion rotates in the hinged groove 211, and the protrusion 111 moves in the limiting groove 212. When the slider 1 rotates to a preset angle with the lower surface of the slider body 2, the protrusion 111 can push the hook 3. When the slider 1 is continuously rotated, the protrusion 111 pushes the hook 3 out of the chain teeth, thereby unlocking the slider body 2. During the rotation of the pull tab 1, a part of the protrusion 111 is always located in the limiting groove 212. The limiting groove 212 can always limit the protrusion 111, restricting the pull tab 1 from moving along the axial direction of the first cross bar 11, thereby reducing the shaking of the pull tab 1 during flipping and use, and improving the use effect of the invisible zipper.

[0048] In the present application, the protrusion 111 can not only limit the movement of the pull tab 1 along the length direction of the first cross bar 11 , but also push the horse hook 3 to unlock the slider body 2 .

[0049] Preferably, the hinge portion of the first crossbar 11 and the protrusion 111 are integrally formed.

[0050] like Figure 3 As shown, the projection 111 is an arc-shaped projection, and when the side of the arc-shaped projection contacts the horse hook 3, the arc-shaped projection can push the horse hook 3. Preferably, the limiting groove 212 is an arc-shaped limiting groove.

[0051] The curvature of the arc-shaped projection determines the size of the preset angle. Preferably, the projection 111 is coaxially arranged with the hinge portion.

[0052] In some embodiments of the present application, the arc angle of the arc-shaped protrusion is 180°, and the pull tab 1 can push the horse hook 3 by rotating a small angle, thereby improving the reliability of unlocking the slider body 2.

[0053] like Fig.10 As shown, the pull tab 1 is located at the first working position, the pull tab 1 is located at the front end of the slider body 2 and the rotation angle is 0°, the protrusion 111 does not apply thrust to the hook 3, and the hook 3 is inserted into the chain tooth;

[0054] like Fig.11As shown, the pull tab 1 is located at the second working position, the pull tab 1 is located at the front end of the slider body 2 and rotated at a certain angle, the angle is less than 90 degrees, the protrusion 111 applies a thrust to the hook 3, the hook 3 is separated from the chain teeth, but the hook 3 is not pushed up to the highest position, when the pull tab 1 continues to rotate to 90 degrees, the protrusion 111 applies a thrust to the hook 3, and the hook 3 is pushed up to the highest position;

[0055] like Fig.11 As shown, the pull tab 1 is located at the third working position, the pull tab 1 is located at the rear end of the slider body 2 and rotated at a certain angle, the angle is greater than 90° and less than 180°, the protrusion 111 applies a thrust to the hook 3, the hook 3 is separated from the chain teeth, and the height of the hook 3 being pushed up is reduced;

[0056] like Fig.12 As shown, the pull tab 1 is located at the fourth working position, the pull tab 1 is located at the rear end of the slider body 2 and rotated by a certain angle, which is close to 180°. The protrusion 111 applies a thrust to the horse hook 3, the horse hook 3 disengages from the chain teeth, and the pushed height of the horse hook 3 decreases.

[0057] Here, the front and back are explained. An engagement outlet is provided at one end of the slider body 2, and two introduction ports are provided at the other end of the slider body 2. In this scheme, the direction where the introduction port of the slider body 2 is located is named as the front, and the direction where the engagement port of the slider body 2 is located is named as the back.

[0058] In the embodiment where the arc angle of the arc-shaped protrusion is 180°, the arc-shaped protrusion rotates 180° with the pull tab 1, and a part of the arc-shaped protrusion is always located in the limiting groove 212, ensuring that the limiting groove 212 can always limit the protrusion 111, thereby solving the problem of shaking of the pull tab 1 during rotation to the greatest extent.

[0059] Preferably, the arc of the arc-shaped protrusion is not greater than 180°.

[0060] The horse hook 3 can be installed on the slider body 2 through its own structure, and can also be installed on the slider body 2 through the spring cover plate 4.

[0061] In the embodiment where the locking slider of the invisible zipper further includes a spring cover plate 4 , the spring cover plate 4 is connected to the slider body 2 and can press the horse hook 3 onto the slider body 2 .

[0062] like Figure 3 As shown, the slider body 2, the pull tab 1, the horse hook 3 and the spring cover plate 4 are arranged in sequence.

[0063] The spring cover plate 4 is provided with a pressing part, which can apply pressure to the hook 3 to drive the hook 3 to move in the direction of inserting the chain teeth, so as to reduce the swing of the pull tab 1 around the axis direction of the first cross bar 11 when it is stationary or rotating. The force applied by the pressing part to the hook 3 is toward the lower surface of the slider body 2.

[0064] The pull tab 1 rotates, the horse hook 3 is lifted, and the pressing part of the spring cover plate 4 is also lifted together. Since the spring cover plate 4 is fixed on the slider body 2, the pressing part will generate a pressure to press the horse hook 3, and then the horse hook 3 transfers the pressure to the first cross bar 11, increasing the rotation damping of the pull tab 1, thereby reducing the swing of the pull tab 1 around the axial direction of the first cross bar 11 when rotating.

[0065] The pull tab 1 is stationary before it is flipped over. After the spring cover plate 4 is installed on the slider body 2, the clamping portion applies pressure to the horse hook 3, and then the horse hook 3 transmits the pressure to the first cross bar 11, increasing the rotation damping of the pull tab 1, thereby reducing the swing of the pull tab 1 around the axial direction of the first cross bar 11 when it is stationary.

[0066] The arrangement of the pressing portion can effectively reduce the swinging of the pull tab 1 around the axis of the first cross bar 11 as the user moves, thereby avoiding the sound of the pull tab 1 and the chain teeth due to collision, and improving the use effect of the invisible zipper.

[0067] The pressing part can continuously apply pressure to the hook 3 during the rotation of the pull tab 1, and before the hook 3 is lifted to the highest position, the force applied by the pressing part to the hook 3 gradually increases with the rotation of the pull tab 1. The hook 3 transmits the pressure to the first cross bar 11, which to a certain extent presses the protrusion 111 into the limiting groove 212, preventing the protrusion 111 from falling out of the limiting groove 212 during the rotation of the pull tab 1, thereby improving the stability and reliability of the use of the locking slider.

[0068] In some embodiments of the present application, the pressing portion is a spring sheet 41 .

[0069] The clamping part always applies pressure to the hook 3. When the pull tab 1 rotates from the front end of the slider body 2 to the rear end of the slider body 2, the hook 3 can be inserted into the chain tooth under the pressure of the clamping part to effectively lock the slider body 2.

[0070] like Figure 8 As shown, the spring piece 41 includes a horizontal section and an arc section, wherein the horizontal section can fit with the hook 3, one end of the arc section is connected to the horizontal section, and the other end of the arc section is connected to the spring piece cover plate 4. When the pull tab 1 rotates, the protrusion 111 pushes the hook 3 to move, and the hook 3 squeezes the horizontal section of the spring piece 41, and the arc section is deformed, and the arc section can apply force to the horizontal section, so that the horizontal section presses the hook 3 downward.

[0071] The arc segment can be Figure 8 In the structure shown, the depression of the arc segment faces the space between the horizontal segment and the elastic cover plate 4; the depression of the arc segment may also face away from the space between the horizontal segment and the elastic cover plate 4 (not shown in the figure).

[0072] The arc segment can be Figure 8The structure shown in the figure has only one bend, but may also be a wavy structure with multiple arc bends (not shown in the figure).

[0073] like Figure 8 As shown, the front end of the horse hook 3 is not inserted into the chain tooth, and the rear end of the horse hook 3 is inserted into the chain tooth. In this solution, the pressing part is arranged at the front end of the spring cover plate 4 to press the front end of the horse hook 3.

[0074] The pressing part can also be arranged in the middle of the spring cover plate 4 (not shown in the figure), and the pressing part presses the middle of the horse hook 3, at which time the front end and / or rear end of the horse hook 3 can extend into the chain teeth.

[0075] The spring cover plate 4 is formed by stamping and bending a piece of elastic metal sheet. Preferably, the spring cover plate 4 and the pressing part are integrally formed.

[0076] In other embodiments of the present application, Fig.14 and 15 As shown, the pressing part further includes an abutment plate 42, which is connected to the spring cover plate 4 and can abut against the position of the corresponding protrusion 111 of the hook 3. In this embodiment, the abutment plate 42 cooperates with the spring 41 to press the hook 3, and the abutment plate 42 and the spring 41 simultaneously apply pressure to the hook 3, which can further reduce the swing of the pull tab 1 around the axis direction of the first cross bar 11 during the static and rotating processes, and at the same time ensure that the protrusion 111 always rotates in the limiting groove 212.

[0077] The position where the abutment plate 42 is set on the spring cover plate 4 needs to be widened, and the abutment plate 42 is made through a cutting process at the widened position of the spring cover plate 4. After the cutting is completed, the abutment plate 42 is bent toward the direction of the horse hook 3 and can abut against the horse hook 3. At the same time, a clearance groove is formed on the spring cover plate 4 for the abutment plate 42 to move.

[0078] The spring sheet 41 and the contact plate 42 are spaced apart from each other along the length direction of the spring sheet cover plate 4 .

[0079] The spring cover plate 4 is fixedly connected to the slider body 2 .

[0080] In some embodiments of the present application, a raised wall 213 is provided on the mold nose 21 of the slider body 2, and a step surface 214 for supporting the spring cover plate 4 is provided on the raised wall 213. The raised wall 213 is deformed by machine punching to press the spring cover plate 4 on the step surface 214. The pressing part is located below the step surface 214 to press the horse hook 3.

[0081] Preferably, a protruding wall 213 is provided at the front end of the slider body 2 and / or the rear end of the slider body 2 to fix the front end and / or the rear end of the elastic sheet cover plate 4 .

[0082] The mold nose 21 is provided with raised walls 213. Preferably, the raised walls 213 are provided in pairs along an axial direction perpendicular to the first crossbar 11.

[0083] like Figure 4 As shown, the front end of the mold nose 21 is provided with a first raised wall 213, and the rear end of the mold nose 21 is provided with a second raised wall 213. The front end of the fixed spring cover plate 4 is on the step surface 214 by machine deformation of the first raised wall 213, and the rear end of the fixed spring cover plate 4 is on the step surface 214 by striking deformation of the second raised wall 213.

[0084] In order to reduce the installation accuracy of the spring cover plate 4 on the mold nose 21, the present application provides a first limiting portion on the mold nose 21, and a second limiting portion on the spring cover plate 4. The first limiting portion cooperates with the second limiting portion to limit the movement of the spring cover plate 4 along the axial direction perpendicular to the first cross bar 11.

[0085] At least one first limiting portion is disposed on the mold nose 21 , and at least one second limiting portion is disposed on the spring cover plate 4 . The positions of the second limiting portions correspond to those of the first limiting portions one by one and the number of the second limiting portions is equal.

[0086] In some embodiments of the present application, the first limiting portion is a limiting protrusion and / or a limiting groove, and the second limiting portion is a limiting groove and / or a limiting protrusion. Specifically, the first limiting portion is a limiting protrusion, and the second limiting portion is a limiting groove; the first limiting portion is a limiting groove, and the second limiting portion is a limiting protrusion.

[0087] When at least two first limiting portions are provided on the mold nose 21, all the first limiting portions may be limiting grooves or limiting protrusions, or a part of the first limiting portions may be limiting grooves and another part of the first limiting portions may be limiting protrusions.

[0088] like Figure 5 As shown, the front end of the mold nose 21 is provided with a first limiting groove, the rear end of the mold nose 21 is provided with a first limiting protrusion, the front end of the spring cover plate 4 is provided with a second limiting protrusion, and the rear end of the spring cover plate 4 is provided with a second limiting groove. During installation, the front end of the mold nose 21 is limitedly matched with the second limiting protrusion of the spring cover plate 4 through the first limiting groove, and the first limiting protrusion at the rear end of the mold nose 21 is limitedly matched with the second limiting groove of the spring cover plate 4, so as to limit the spring cover plate 4 along the axis direction perpendicular to the first crossbar 11.

[0089] like Figure 3 and Figure 8 As shown, the spring cover plate 4 is provided with a bend, which is toward the horse hook 3, for increasing the distance between the spring cover plate 4 and the horse hook 3, forming a clearance space, ensuring that the horse hook 3 can be pushed and lifted to the highest position by the protrusion 111, and reducing the interference with the flipping of the pull tab 1.

[0090] The horse hook 3 is a U-shaped horse hook, which includes a rear vertical rod, a second horizontal rod and a front vertical rod, and the rear vertical rod and the front vertical rod are located at both ends of the length direction of the second horizontal rod. In this solution, the length of the rear vertical rod is greater than that of the front vertical rod, and the rear vertical rod can be inserted into the chain teeth, the front vertical rod is not inserted into the chain teeth, and the position of the second horizontal rod close to the front vertical rod cooperates with the pressing part of the spring cover plate 4. When the protrusion 111 pushes the horse hook 3, the rear vertical rod and the second horizontal rod are pushed up, and the rear vertical rod is pulled out from the chain teeth.

[0091] As the protrusion 111 is pushed, the rear end vertical rod is lifted. At this time, the height of the connection position between the rear end vertical rod and the second cross rod is higher than that of other positions of the horse hook 3. In order to prevent the connection position between the rear end vertical rod and the second cross rod from contacting the spring cover plate 4, the present application provides an inclined rod at the connection position between the rear end vertical rod and the second cross rod, that is, the rear end vertical rod and the second cross rod are connected by the inclined rod, and the inclined rod is inclined from the second cross rod to the lower surface of the slider body 2, thereby lowering the height there, preventing the spring cover plate 4 from hindering the movement of the horse hook 3, and not affecting the flipping of the pull tab 1.

[0092] The horse hook 3 is formed by punching and bending a hard metal sheet with a certain elasticity.

[0093] like Fig. 9 As shown, the second cross bar includes a first straight segment, an inclined segment and a second straight segment connected to each other, wherein the first straight segment is connected to the front vertical bar, the second straight segment is connected to the diagonal bar, the inclined segment is located between the first straight segment and the second straight segment, there is a height difference between the first straight segment and the second straight segment, and the second straight segment is away from the lower surface of the slider body 2 relative to the first straight segment.

[0094] The hook 3 is mounted on the mold nose 21 of the slider body 2. The front end of the mold nose 21 is provided with a hook front end slot 215. The rear end of the mold nose 21 is provided with a hook hole 216. The hook hole 216 is connected to the inner cavity of the slider body 2. The rear end vertical rod of the hook 3 passes through the hook hole 216 and is inserted into the chain tooth. The front end vertical rod of the hook 3 is inserted into the hook front end slot 215. After the pull tab 1 is mounted on the mold nose 21, the hinge portion of the first crossbar 11 of the pull tab 1 protrudes from the hinge groove 211. The first straight line segment can be pressed against the front end of the mold nose 21, and the second straight line segment can be pressed against the hinge portion protruding from the hinge groove 211.

[0095] In order to further optimize the above technical solution, a slot for embedding the hook 3 is provided on the first crossbar 11, and the width of the slot is close to the width of the hook 3. The slot and the hook 3 are limited to reduce the shaking of the pull tab 1 along the axis direction of the first crossbar 11 during the flipping process. In this embodiment, the first crossbar 11 is effectively limited by the limited cooperation between the slot and the hook 3, and the limited cooperation between the protrusion 111 and the limited groove 212, so as to reduce the shaking of the pull tab 1 along the axis direction of the first crossbar 11 during the flipping process.

[0096] Preferably, the locking groove and the protrusion 111 are arranged opposite to each other on both sides of the axial direction of the first cross bar 11 .

[0097] like Figure 6 As shown, the middle part of the pull tab 1 is provided with a bend. When the pull tab 1 is at the front end of the slider body 2, the rear end height of the pull tab 1 is lower than the front end height of the pull tab 1, thereby reducing the distance between the pull tab 1 and the chain teeth when the pull tab 1 is stationary.

[0098] The locking slider of the invisible zipper disclosed in the present application improves the stability and user experience of the product by changing the structure of the pull tab 1 and the slider body 2, and ensures that the pull tab 1 does not shake; the appearance of the slider is slightly changed and the size of the slider is not increased too much; the structure is simple, and the connection of the components is achieved by machine striking, which is easy to install and produce.

[0099] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used, and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. The scope of application involved in the present application is not limited to the technical solution formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned application concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in this application (but not limited to) to form a technical solution.
