[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] The core of the present invention is to provide a pull tab structure that is convenient for assembly. Another core of the present invention is to provide a zipper including the above pull tab structure, and its pull tab is convenient for assembly.

[0047] In the first specific embodiment of the pull tab structure provided by the present invention, it can be applied to zippers, sleeping bags, and tents. Please refer to FIGS. 1 to Figure 16 , and this pull tab structure includes a pull tab 300, a first protective cover 100, and a second protective cover 200.

[0048] The pull tab 300 includes an upper bottom plate 311, a lower bottom plate 312, and a connecting column 310. The upper bottom plate 311 is fixed above the lower bottom plate 312 through the connecting column 310 to form the main body of the pull tab 300. Specifically, the upper and lower ends of the connecting column 310 are respectively connected to the front end of the bottom surface of the upper bottom plate 311 and the front end of the top surface of the lower bottom plate 312. Specifically, as Figure 5 shown, when the connecting column 310 makes a cross-section in the horizontal direction, the cross-section presents a cam shape, so that the teeth on both sides of the zipper are separated and joined at the tail end of the connecting column 310.

[0049] As Figures 2 to 5As shown in the figure, two protruding blocks 112 are sequentially arranged on the upper edge of the first protective cover 100 in the left-right direction. An accommodation gap L extending in the front-back direction is formed between the two protruding blocks 112. The front end of the bottom surface of the protruding block 112 is fixed to the top surface of the first protective cover 100, and the rear half part of the bottom surface of the protruding block 112 is suspended, and includes a positioning surface 112b and a cutting surface 112a which are sequentially arranged and butt-jointed from front to back. The cutting surface 112a extends obliquely upward from front to back. Specifically, as Figure 2 shown, the positioning surface 112b is a horizontal plane, and the included angle A between the rearward extension surface of the positioning surface 112b and the cutting surface 112a is specifically an acute angle. Of course, the positioning surface 112b can also be a plane in other orientations with an included angle greater than 0 with the cutting surface 112a. The top surface of the lower bottom plate 312 can move along the cutting surface 112a, so that the connecting column 310 enters the accommodation gap L, and then the positioning surface 112b contacts the top surface of the lower bottom plate 312 by swinging the pull head 300.

[0050] As Figure 7 shown, the second protective cover 200 is snap-connected above the first protective cover 100 to form a main cover body, and at least part of the structure of the pull head 300 is built into the main cover body to be protected by the main cover body.

[0051] When assembling the first protective cover 100 and the pull head 300, as Figure 3 shown, the front end of the top surface of the lower bottom plate 312 of the pull head 300 slides forward along the cutting surface 112a on the protruding block 112, so that the connecting column 310 gradually enters the accommodation gap L. After that, as Figure 4 shown, with the connecting column 310 as a fulcrum, the pull head 300 is swung, so that the positioning surface 112b abuts against the top surface of the lower bottom plate 312 and the bottom surface of the upper bottom plate 311 abuts against the top surface of the protruding block 112, and the assembly between the pull head 300 and the first protective cover 100 is completed. After that, the second protective cover 200 is installed above the first protective cover 100 and snap-connected. Among them, the second protective cover 200 is snap-connected above the first protective cover 100 to form a main cover body, and at least part of the structure of the pull head 300 is built into the main cover body.

[0052] In this embodiment, based on the setting of the cutting surface 112a, when the pull head 300 is installed on the first protective cover 100, the possibility of interference between the structure on the lower bottom plate 312 and the first protective cover 100 can be reduced, and the assembly of the first protective cover 100 and the pull head 300 can be completed by means of the accommodation gap L, the connecting column 310, and the cooperation between the protruding block 112 and the upper and lower bottom plates. After that, the second protective cover 200 can be buckled and snap-connected above the first protective cover 100, and the assembly is convenient.

[0053] Further, the first protective cover 100 includes a first front rod 118, a first tail rod 117 disposed behind the first front rod 118, and two first side rods 119 disposed between the first front rod 118 and the first tail rod 117. The first front rod 118, the first tail rod 117, and the two first side rods 119 enclose an annular structure and a first through hole 130 is formed in the middle. A lower side tab mounting portion 330 is fixedly provided on the bottom surface of the lower bottom plate 312, and is specifically connected to the lower bottom plate 312 through a lower side mounting base 331. In addition, a protrusion block 112 is provided on the first front rod 118, specifically at the rear end of the top surface of the first front rod 118, and the two protrusion blocks 112 are specifically symmetrically arranged. Two lower blocking portions 313 are sequentially arranged along the left-right direction at the tail end of the top surface of the lower bottom plate 312, and the two lower blocking portions 313 are symmetrically arranged. The lower side tab mounting portion 330 extends downward through the first through hole 130 for connecting a tab.

[0054] Further, as Figure 1 shown, the second protective cover 200 includes a second front rod 217, a second tail rod 216 disposed behind the second front rod 217, and two second side rods 218 disposed between the second front rod 217 and the second tail rod 216. The second front rod 217, the second tail rod 216, and the two second side rods 218 enclose an annular structure and a second through hole 230 is formed in the middle. An upper side tab mounting portion 320 is fixedly provided on the top surface of the upper bottom plate 311, and is specifically connected to the upper bottom plate 311 through an upper side mounting base 321. The upper side tab mounting portion 320 extends upward through the second through hole 230. By setting the second protective cover 200 as an annular structure, the protection effect on the upper bottom plate 311 can be ensured.

[0055] In addition, as Figure 1 shown, two upper blocking portions 314 are sequentially arranged along the left-right direction at the tail end of the bottom surface of the upper bottom plate 311, and the two upper blocking portions 314 are symmetrically arranged. The two upper blocking portions 314 and the two lower blocking portions 313 are oppositely arranged along the up-down direction, and the upper blocking portions 314 and the lower blocking portions 313 limit the chain teeth in the inner cavity of the slider 300 body.

[0056] Among them, since the slider is provided with an upper side tab mounting portion 320 and a lower side tab mounting portion 330, tabs can be respectively connected, and this slider structure constitutes a slider structure for double-sided use. Of course, in other embodiments, the slider structure can also be provided with only one of the upper side tab mounting portion 320 and the lower side tab mounting portion 330, which connects a tab to form a slider for single-sided use, and the protective cover has strong versatility.

[0057] Further, as Figure 8 and Figure 13As shown, a snap-through hole 211 is provided through the second front-end rod 217 in the up-down direction. A snap block 211c is fixedly provided on the hole wall of the snap-through hole 211. A snap portion 111 is provided on the top surface of the first front-end rod 118. The snap portion 111 has a certain elasticity, specifically a plastic part or a metal part. The snap portion 111 extends into the snap-through hole 211 and is snapped onto the snap block 211c. Since the snap position is inside the snap-through hole 211, the reliability of the snap connection can be ensured, and the snap position can be prevented from unlocking by itself during use.

[0058] Further, as Figures 13 to 15 shown, the top surface and the bottom surface of the snap block 211c are gradually inclined downward from the middle of the snap-through hole 211 towards its hole wall. Optionally, two snap blocks 211c are provided in the left-right direction, specifically symmetrically. Optionally, on the same snap block 211c, the top surface of the snap block 211c is a locking surface 211b, and the bottom surface is a locking inclined surface 211a, and both are in the same inclined direction as the snap block 211c. The snap portion 111 passes through the snap block 211c by deformation, and then the snap portion 111 hooks the snap block 211c through its reset movement with its barb structure 111a. The inclined setting of the snap block 211c has a guiding effect on the snap portion 111 and can further ensure the reliability of the snap connection.

[0059] Further, as Figure 11 and Figure 12 shown, a limiting recess 110 is provided on the front edge of the top surface of the first front-end rod 118, specifically in a strip shape. A limiting protrusion 210 is provided at the front end of the bottom surface of the second front-end rod 217. The limiting protrusion 210 extends downward into the limiting recess 110, and the rear end surface of the limiting protrusion 210 contacts the front end surface of the limiting recess 110 to limit the first protective cover 100 and the second protective cover 200 in the front-rear direction. Optionally, on the first protective cover 100, the limiting recess 110, the snap portion 111, and the protrusion block 112 are arranged in sequence from front to back, where the protrusion block 112 and the snap portion 111 are both higher than the top surface of the first front-end rod 118.

[0060] Further, as Figure 1 shown, a receiving groove 212 is provided at the tail end of the bottom surface of the second front-end rod 217. The protrusion block 112 extends upward into the receiving groove 212, and the protrusion block 112 contacts and cooperates with the side surface of the receiving groove 212 in the left-right direction to limit the first protective cover 100 and the second protective cover 200 in the left-right direction. Of course, the front end of the protrusion block 112 and the front end of the receiving groove 212 can also contact to limit in the front-rear direction.

[0061] During the assembly process, the second protective cover 200 and the first protective cover 100 are assembled after the first protective cover 100 and the pull head 300 are assembled. At this time, as Figure 6 and Figure 7As shown, the buckle portion 111 contacts the locking inclined surface 211a through the buckle through-hole 211. Through the action of the inclined surface, the buckle portion 111 is extruded and gradually approaches the locking surface 211b. The buckle portion 111 returns to the normal state through elasticity. The barb structure 111a at the tail end of the buckle portion 111 contacts and engages with the locking surface 211b, making it impossible to separate the first protective cover 100 and the second protective cover 200, and positioning the first protective cover 100 and the second protective cover 200 in the up and down directions. At the same time, the limiting protrusion 210 reaches the limiting recess 110, positioning the first protective cover 100 and the second protective cover 200 in the front and back directions. The protruding block 112 reaches the receiving groove 212, positioning the first protective cover 100 and the second protective cover 200 in the left and right directions. Through multi-point positioning, the first protective cover 100 and the second protective cover 200 are positioned in six three-dimensional directions, and the installation of the two protective covers is more secure. The second protective cover 200 is arranged on the upper side of the pull head 300 and contacts the upper bottom plate 311.

[0062] Furthermore, as Figure 8 shown, on the top surface of the first side rod 119, the first front plane 122, the slope surface 114, and the first rear plane 115 that are butt-jointed in sequence from front to back. The first front plane 122 and the first rear plane 115 are horizontally arranged, and the slope surface 114 gradually decreases from front to back. Specifically, the first rear plane 115 is lower than the first front plane 122. As Figure 12 shown, a horizontal second cover plane 214 is provided on the bottom surface of the second side rod 218. Different parts of the second cover plane 214 are respectively located above the first front plane 122, the slope surface 114, and the first rear plane 115, and there is a gap between the first front plane 122 and the second cover plane 214.

[0063] Among them, as Figure 11 shown, at both ends of the top surface of the first front rod 118 in the left and right directions, first channels 113 are respectively provided at the butt-joints with the first side rod 119. As Figure 15 shown, at both ends of the bottom surface of the second front rod 217 in the left and right directions, second channels 213 are respectively provided at the butt-joints with the second side rod 218. The two second channels 213 are respectively buckled above the two first channels 113 in a one-to-one correspondence to form two complete chain tooth channels, which are respectively used for the two chain tooth strips in the zipper to pass through. Preferably, the first channel 113 and the second channel 213 can be curved grooves, and the curves fit the surface of the chain teeth, so that the unilateral chain tooth strip in the zipper can pass through without obstruction.

[0064] In this embodiment, since the front plane 122 of the first cover body at the front end of the top surface of the first side rod 119 is slightly higher than the rear plane 115 of the first cover body at its rear side, and the front plane 122 of the first cover body is relatively close to the plane 214 of the second cover body, the zipper tape in the zipper cannot enter the inner cavity of the slider 300 from the front end, which can prevent the fabric from getting stuck.

[0065] Furthermore, the bottom surface of the first protective cover 100 and the top surface of the second protective cover 200 include curved surfaces. Optionally, the middle of the bottom surface of the first protective cover 100 is low and the periphery is high, and the middle of the top surface of the second protective cover 200 is high and the periphery is low.

[0066] Optionally, as Figure 9 shown, the bottom surface of the first side rod 119 includes a first arc surface 121, the bottom surface of the first front rod 118 is a front curved surface 120, and the left and right ends of the front curved surface 120 are respectively butted against the first arc surfaces 121 of the two first side rods 119.

[0067] Among them, since the slider 300 is assembled and limited with the first protective cover 100 through its connecting column 310, without relying on the abutment between the first protective cover 100 and the lower bottom plate 312 in the up and down direction, the shape and size setting of the first through hole 130 has greater freedom.

[0068] Specifically, as Figure 5 shown, the outer side surface of the lower bottom plate 312 is located inside the inner peripheral surface of the first through hole 130, which can reduce the limitation of the swing angle range of the tab on the lower tab mounting portion 330 by the first protective cover 100 and increase the swing angle range of the tab on the lower tab mounting portion 330 thereon.

[0069] More specifically, as Figure 5 and Figure 9 shown, the inner side surface 116 of the first side rod of the first side rod 119 for forming the hole wall of the first through hole 130 is arranged in imitation of the cross section of the lower bottom plate 312. In addition, as Figure 10 shown, the first through hole 130 includes a first main hole and a U-shaped first receiving through hole 131 docked in front of it, and the protruding block 112 extends backward into the upper part of the first receiving through hole 131, so as to install the protruding block 112 with the lower bottom plate 312 and adapt to the shape of the lower bottom plate 312.

[0070] Among them, since the slider 300 is assembled and limited with the first protective cover 100 through its connecting column 310, without relying on the abutment between the first protective cover 100 and the lower bottom plate 312 in the up and down direction, the shape and size setting of the first through hole 130 has greater freedom. Specifically, as Figure 5As shown, the outer side surface of the lower bottom plate 312 is located inside the inner peripheral surface of the first through hole 130, which can reduce the limitation of the swing angle range of the tab on the lower tab mounting portion 330 by the first protective cover 100 and increase the swing angle range of the tab on the lower tab mounting portion 330. More specifically,

[0071] Optionally, as Figure 13 shown, the top surface of the second side rod 218 is a second arc surface 220.

[0072] Among them, since the slider 300 realizes the assembly and limit with the first protective cover 100 through its connecting column 310, and the first protective cover 100 and the second protective cover 200 are snap-connected, without the need to limit the two through the abutment of the second protective cover 200 and the upper bottom plate 311 in the up and down direction, the shape and size setting of the second through hole 230 has greater freedom.

[0073] Specifically, the outer side surface of the upper bottom plate 311 is located inside the inner peripheral surface of the second through hole 230, which can reduce the limitation of the swing angle range of the tab on the upper tab mounting portion 320 by the second protective cover 200 and increase the swing angle range of the tab on the upper tab mounting portion 320.

[0074] More specifically, the inner side surface 215 of the second side rod 218 that forms the hole wall of the second through hole 230 is arranged in imitation of the cross section of the upper bottom plate 311. In addition, the second through hole 230 includes a second main hole and a U-shaped second receiving through hole 231 docked in front of it to adapt to the shape of the upper bottom plate 311.

[0075] Optionally, as Figure 5 shown, the outer side surface 132 of the first side rod 119 includes a convex arc surface. On the first side rod 119, the inner side surface 116 and the outer side surface 132 of the first side rod are oppositely arranged. As Figure 13 shown, the outer side surface 232 of the second side rod 218 includes a convex arc surface. On the second side rod 218, the inner side surface 215 and the outer side surface 232 of the second side rod are oppositely arranged. Preferably, the outer side surface 132 of the left first side rod is aligned with the outer side surface 232 of the second side rod up and down, and the outer side surface 132 of the right first side rod is aligned with the outer side surface 232 of the second side rod up and down. As Figure 16 shown, based on the convex shape setting of the outer side surface 132 of the first side rod and the outer side surface 232 of the second side rod, the width of the first side rod 119 and the second side rod 218 in the left and right directions can be enlarged, and the left and right sides of the main cover body are in a bulging structure, which can reduce the risk of cloth jamming.

[0076] After the first protective cover 100 is assembled with the lower bottom plate 312, the first protective cover 100 contacts the lower bottom plate 312, and the lower bottom plate 312 reaches the first through hole 130. Under specific circumstances, the lower bottom plate 312, the lower blocking portion 313, and the inner side surface 116 of the first side rod may contact each other. The lower bottom plate 312 is slightly smaller than the first through hole 130 to ensure that the slider 300 will not escape from the first through hole 130. The rear plane 115 of the first cover body can block the contact between the inner cavity of the slider 300 and the outside world, preventing foreign objects from getting stuck.

[0077] In this embodiment, due to the setting of the curved surface, the connection between different positions of the bottom surface of the first protective cover 100 and the top surface of the second protective cover 200 is gentle and the transition is natural. At the same time, the slider structure contacts the skin through a large arc surface, making it more skin-friendly.

[0078] In the slider structure of this embodiment, the installation of the slider and the first protective cover is achieved by means of the connecting column 310, which makes the operation more convenient and not prone to misoperation. By setting the changing trend of the gap between the top surface of the first protective cover and the second protective cover, it is possible to prevent the cloth from getting stuck. Pull tabs 400 are provided on both the upper and lower sides of the slider.

[0079] In addition to the above slider structure, the present invention also provides a zipper, which includes a slider structure, specifically the slider structure provided in any of the above embodiments, and the beneficial effects can be correspondingly referred to the above respective embodiments. In addition, the zipper further includes zipper tapes 510. On the edges of the two zipper tapes 510 close to each other, there are respectively provided chain tooth strips composed of continuously arranged spiral chain teeth 520, and the chain tooth strips extend into the slider 300. The protective cover and the slider 300 limit each other, that is, the protective cover slides together with the slider 300. In addition, the overall shape of the protective cover is wider and thicker than the slider 300, and during the pulling and sliding process, the inner cavity of the slider 300 is kept away from the cloth, which can effectively prevent foreign objects from getting stuck in the inner cavity of the slider.
