Description
Technical Field
[0001] This application relates to the field of zippers, and more particularly to a corn-tooth zipper. Background Technology
[0002] In existing zipper designs, to improve the meshing performance and stability of the zipper teeth, a groove is usually created on the tooth tip to allow the zipper head to tightly engage the tooth and slide smoothly. However, this groove creates a narrow meshing area between the tooth tip and the tooth body, making the tooth structure in this area relatively weak. Under prolonged use or significant external force, this area is prone to breakage, causing the tooth tip to separate from the tooth body and rendering the zipper unusable. This not only affects the product's lifespan but also causes inconvenience to the user.
[0003] Therefore, there is a need for a corn tooth zipper that prevents breakage between the tooth body and the tooth tip. Utility Model Content

[0032] An embodiment of the present application provides a corn tooth zipper, comprising a zipper cloth and a corn tooth provided on the zipper cloth, wherein the corn tooth comprises:
[0033] a tooth body and a tooth head integrally provided on the tooth body;
[0034] The clamping portion is protruded on the tooth head, and the clamping portion and the tooth body form a clamping groove.
[0035] The clamping portion of one zipper can be inserted into and clamped in the clamping groove of another zipper.
[0036] The corn tooth zipper provided above, through the chain tooth composed of the tooth body and the tooth head integrally arranged thereon, the clamping portion protruded on the tooth head and the tooth body form a clamping groove, when the chain teeth of two zippers cooperate with each other, the clamping portion of one zipper can be precisely inserted into and clamped in the clamping groove of another zipper, which enhances the engagement tightness and engagement area between the chain teeth. Significantly reduces the risk of tooth head and tooth body breaking due to long-term use or external force, thereby prolonging the service life of the zipper and improving the user experience.
[0037] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.
[0038] According to Figures 1-7 , the corn tooth zipper 100 provided in the embodiments of the present application includes a zipper cloth and a chain tooth 10 arranged on the zipper cloth, the chain tooth 10 includes a tooth body 11 and a tooth head 12 integrally arranged on the tooth body 11; a clamping portion 13 protruded on the tooth head 12, and the clamping portion 13 and the tooth body 11 form a clamping groove 14; wherein the clamping portion 13 of one zipper can be inserted into and clamped in the clamping groove 14 of another zipper.
[0039] Specifically, the tooth head 12 and the tooth body 11 form an integrated structure, so that the tooth head 12 and the tooth body 11 form a continuous material structure, and in the length direction of the tooth body 11, the cross-sectional area of the tooth head 12 gradually decreases in the direction of the tooth body 11 towards the tooth head 12, forming a gradual transition structure. The integrated structure significantly improves the overall structural strength of the chain tooth 10, reduces the risk of breaking when used for a long time or subjected to external force.
[0040] Further, the clamping portion 13 is integrally formed with the tooth head 12. The clamping portion 13 extends outwardly from the front edge of the tooth head 12, so that the protruding clamping portion 13 and the side wall of the tooth body 11 form a clamping groove 14, which is used to achieve close engagement between the chain teeth 10. In the length direction of the tooth body 11, the clamping groove 14 is formed from the tooth head 12 to the extension direction of the tooth body 11, so that the clamping groove 14 for engaging the chain teeth 10 is formed in the tooth body 11, so that the clamping groove 14 is adjacent to the continuous tooth body 11, which can abut the tooth head 12 of another chain tooth 10, thereby increasing the contact area when the two chain teeth 10 are engaged, and the engagement force can be dispersed to a wider area, reducing the problem that the stress is concentrated in a narrow engagement area when the traditional engagement groove is arranged on the chain under stress, which easily leads to breakage.
[0041] Further, in the thickness direction of the tooth body 11 and the tooth head 12, the thickness of the tooth head 12 is less than the thickness of the tooth body 11, so that when one chain tooth 10 is engaged with another chain tooth 10, the clamping portion 13 of one chain tooth 10 extends into the clamping groove 14 of another chain tooth 10, and at this time, the tooth head 12 of one chain tooth 10 abuts the tooth body 11 of another chain tooth 10.
[0042] In summary, when two chain teeth 10 on the zipper fabric are close to each other, the clamping portion 13 of one zipper will extend into the clamping groove 14 of the other zipper, forming close engagement, and the tooth head 12 of one chain tooth 10 abuts the tooth body 11 of another chain tooth 10, increasing the engagement area between the two chain teeth 10.
[0043] In a specific embodiment, the clamping portion 13 has a clamping surface 131 and a connecting surface 132, the connecting surface 132 is arranged on the tooth head 12, the clamping surface 131 and the connecting surface 132 are oppositely arranged in the thickness direction of the tooth head 12, and the cross-sectional area of the clamping surface 131 is less than that of the connecting surface 132.
[0044] Specifically, the clamping surface 131 is the surface of the clamping portion 13 for engaging with the clamping groove 14 of another chain tooth 10, thereby ensuring that the zipper can form close engagement when closed, and ensuring the sealing and stability of the zipper. The connecting surface 132 is the part of the clamping portion 13 connected with the tooth head 12.
[0045] Further, since the connecting surface 132 is arranged on the tooth head 12, and the cross-sectional area of the connecting surface 132 is greater than that of the clamping surface 131, so that in the thickness direction of the tooth head 12, when the clamping portion 13 protrudes outwardly, the cross-sectional area of the clamping portion 13 gradually decreases. And the clamping groove 14 engaged with the clamping portion 13 is also arranged to gradually decrease in cross-sectional area along the depth direction of the groove, so that the clamping portion 13 of one chain tooth 10 can engage and clamp the clamping groove 14 of another chain tooth 10.
[0046] In summary, when two fastener elements 10 on two fastener tapes are close to each other, the clamping portion 13 of one fastener element 10 will slide along the clamping groove 14 of the other fastener element 10 and gradually extend into the clamping groove 14.
[0047] In an embodiment, the clamping portion 13 further comprises a first inclined surface 133 and a second inclined surface 134, both of which are connected to the connecting surface 132 at one end and to the clamping surface 131 at the other end; wherein the first inclined surface 133 is arranged towards the clamping groove 14, and the second inclined surface 134 is arranged away from the clamping groove 14.
[0048] Specifically, the first inclined surface 133 and the second inclined surface 134 together form a convex structure of the clamping portion 13 with the connecting surface 132 and the clamping surface 131. The first inclined surface 133 is arranged towards the clamping groove 14, and when two fastener elements 10 are close to each other, the first inclined surface 133 guides the clamping portion 13 of one fastener element 10 to smoothly enter the clamping groove 14 of the other fastener element 10, so that the first inclined surface 133 of one fastener element 10 is in close contact with the first inclined surface 133 of the other fastener element 10. This reduces the friction and resistance during engagement of the fastener elements 10, making the sliding of the fastener more smooth.
[0049] Further, the second inclined surface 134 is arranged away from the clamping groove 14, and when the clamping portion 13 of one fastener element 10 smoothly enters the clamping groove 14 of the other fastener element 10, the second inclined surface 134 of one fastener element 10 is in close contact with one side of the clamping groove 14 of the other fastener element 10 to engage the two fastener elements 10.
[0050] In an embodiment, the clamping groove 14 has a first surface 141, which is arranged opposite to the first inclined surface 133; wherein when the clamping portion 13 of one fastener element 10 can extend into and be clamped in the clamping groove 14 of the other fastener element 10, the first surface 141 of one fastener element 10 can be in close contact with the second inclined surface 134 of the other fastener element 10.
[0051] Specifically, the close contact between the first surface 141 and the second inclined surface 134 increases the contact area between the fastener elements 10 during engagement, thereby improving the stability of engagement. This design allows the fastener to better distribute stress and reduce the risk of breakage when subjected to external forces. Through the close contact between the first surface 141 and the second inclined surface 134, the slider can more smoothly pass through the fastener elements 10 during sliding, reducing jamming and friction and improving the user experience of the fastener. Due to the increase in engagement area and effective stress distribution, the structural strength of the fastener elements 10 is significantly improved, thereby prolonging the service life of the fastener.
[0052] In summary, when the two fasteners 10 on the two fastener tapes are close to each other, the clamping portion 13 of one fastener gradually extends into the clamping groove 14 of the other fastener along the guide of the second slope 134. In this process, the first surface 141 of one fastener gradually contacts and fits the second slope 134 of the other fastener, and the first slope 133 of one fastener contacts and fits the first slope 133 of the other fastener, thereby forming a close engagement. Due to the fitting of the first surface 141 and the second slope 134 and the fitting of the first slope 133 and the second slope 134, the engagement area between the fasteners 10 is significantly increased, thereby improving the stability and sliding performance of the engagement.
[0053] In an embodiment, the clamping groove 14 has a second surface 142 and a third surface 143, the first surface 141 and the third surface 143 are sequentially connected to form the clamping groove 14, and along the length direction of the tooth body 11, a first included angle is formed between the second surface 142 and the first surface 141, a second included angle is formed between the third surface 143 and the first surface 141, and as viewed along the central plane of the first surface 141, the first included angle and the second included angle are symmetrically distributed.
[0054] Specifically, the symmetrically distributed included angles make the shape of the clamping groove 14 more stable, and when the clamping portions 13 of the two fasteners 10 engage with each other, a closer engagement relationship can be formed. This not only improves the engagement stability of the fastener, but also reduces the problem of poor sliding or falling off of the fastener due to loose engagement.
[0055] In an embodiment, the tooth body 11 has a first abutting surface 111 and a second abutting surface 112, the first abutting surface 111 and the second abutting surface 112 are respectively arranged adjacent to the two sides of the clamping groove 14, and the first abutting surface 111 connects the second surface 142, and the second abutting surface 112 connects the third surface 143.
[0056] Specifically, the first abutting surface 111 and the second abutting surface 112 are respectively connected to the two sides (i.e., the second surface 142 and the third surface 143) of the clamping groove 14, and smoothly transitionally connected to the side wall of the clamping groove 14 (40), and the clamping groove 14 extends from the tooth head 12 to the length direction of the tooth body 11 to form two bosses on the two sides of the clamping groove 14, and the first abutting surface 111 and the second abutting surface 112 are the table surfaces of the two bosses. When the two fasteners 10 are connected and clamped, the first abutting surface 111 of one fastener 10 is connected and fitted with the second abutting surface 112 of the other fastener 10, thereby increasing the clamping area between the two fasteners 10.
[0057] Further, when the clamping portion 13 of the two sprocket teeth 10 are engaged with the clamping groove 14, the contact between them will generate certain stress. Through the first abutting surface 111 and the second abutting surface 112, these stresses can be more evenly distributed to the overall structure of the sprocket tooth 10, thereby reducing the stress on a single area and improving the durability of the sprocket tooth 10.
[0058] In a specific embodiment, the tooth head 12 has a third abutting surface 121, which is arranged adjacent to the clamping portion 13, and the third abutting surface 121 is in the same plane as the connecting surface 132.
[0059] Specifically, the third abutting surface 121 serves as the contact surface between the tooth head 12 and the tooth body 11 of the adjacent sprocket tooth 10, ensuring uniform distribution of force during engagement and avoiding local stress concentration. The third abutting surface 121 is coplanar with the connecting surface 132, forming a continuous planar structure that ensures uniform contact of the contact surface during engagement and reduces engagement errors caused by uneven surfaces.
[0060] Further, when the two sprocket teeth 10 are closed, the clamping portion 13 of one sprocket tooth 10 slides along the first inclined surface 133 and the second inclined surface 134 into the clamping groove 14 of the other sprocket tooth 10, and the first abutting surface 111 of one sprocket tooth 10 abuts and abuts with the second abutting surface 112 of the other sprocket tooth 10, so that the third abutting surface 121 of one sprocket tooth 10 abuts with the tooth body 11 of the other sprocket tooth 10, thereby increasing the engagement area between the two sprocket teeth 10, and the engagement force is evenly transmitted to the tooth body 11 main body through the third abutting surface 121, ensuring uniform distribution of force during engagement and avoiding local stress concentration.
[0061] In a specific embodiment, the tooth body 11 has an abutting portion 113, which is arranged adjacent to the clamping groove 14, and the abutting portion 113 can abut with the third abutting surface 121.
[0062] Specifically, during the engagement of the sprocket tooth 10, the abutting portion 113 of the tooth body 11 abuts and closely contacts with the third abutting surface 121 of the tooth head 12, forming an additional support point, increasing the engagement area between the sprocket teeth 10, and helping to prevent the sprocket teeth 10 from deforming or breaking when subjected to external forces. This design significantly improves the durability and reliability of the sprocket tooth 10.
[0063] In a specific embodiment, the tooth body 11 also has a first connecting portion 114 and a second connecting portion 115 arranged opposite to the first connecting portion 114, and the first connecting portion 114 and the second connecting portion 115 are arranged on the abutting portion 113.
[0064] Specifically, the relative arrangement of the first connecting part 114 and the second connecting part 115 allows the first connecting part 114 and the second connecting part 115 to clamp the zipper cloth, so that the tooth body 11 can be more firmly fixed on the zipper cloth, reducing the risk of loosening or falling off of the tooth body 11 due to external force. The first connecting part 114 and the second connecting part 115 are arranged on the abutting part 113, realizing effective connection between the chain tooth 10 and the zipper cloth.
[0065] Further, the tooth head 12 and the tooth body 11 form an integrated structure, so that the tooth head 12 and the tooth body 11 form a continuous material structure, and in the length direction of the tooth body 11, the cross-sectional area of the tooth head 12 gradually decreases in the direction of the tooth body 11 towards the tooth head 12, forming a gradual transition structure, and a connecting angle is formed in the interval between the first connecting part 114 and the second connecting part 115, for clamping the zipper cloth.
[0066] In a specific embodiment, the chain tooth 10 is made of stainless steel.
[0067] Specifically, the chain tooth made of stainless steel enhances the strength of the overall zipper, reduces the risk of breaking of the tooth head 12 and the tooth body 11 due to long-term use or external force, thereby prolonging the service life of the zipper and improving the user experience.
[0068] Therefore, the above-mentioned corn tooth zipper 100 is composed of a chain tooth 10 composed of a tooth body 11 and a tooth head 12 integrally arranged thereon. The clamping part 13 protruding from the tooth head 12 and the tooth body 11 cleverly form a clamping groove 14. When the chain teeth 10 of two zippers cooperate with each other, the clamping part 13 of one zipper can accurately extend into and clamp in the clamping groove 14 of the other zipper, enhancing the engagement tightness and engagement area between the chain teeth 10. Significantly reduces the risk of breaking of the tooth head 12 and the tooth body 11 due to long-term use or external force, thereby prolonging the service life of the zipper and improving the user experience.
[0069] The above-mentioned is only an embodiment of the present application, and it should be pointed out that for those skilled in the art, without departing from the creative concept of the present application, improvements can be made, but these all belong to the protection scope of the present application.
