In one possible embodiment, a first inclined surface is connected between the rib 140 and the tooth body 110, and the first inclined surface is in arc transition connection with the tooth body 110. In a specific application, the first inclined surface is connected between the reinforcing rib 140 and the tooth body 110, and the first inclined surface can enhance the connection strength between the engaging head 120 and the tooth body 110, and in addition, the first inclined surface is in arc transitional connection with the tooth body 110, so that the extrusion stress applied to the engaging head 120 and the tooth body 110 can be prevented from being concentrated on the root parts of the engaging head 120 and the tooth body 110, and the engaging head 120 and the tooth body 110 can be prevented from being separated.

Referring to fig. 1 to 3, as an embodiment, two engaging grooves 130 are provided, and the two engaging grooves 130 are respectively provided at opposite sides of the tooth body 110. In a specific application, since the engaging grooves 130 are provided at both sides of the body 110, in the slide fastener 200, the coupling elements 100 at both sides are alternately engaged, that is, during use of the slide fastener 200, the engaging head 120 of one coupling element 100 is engaged with the engaging groove 130 at one side of the body 110, and the engaging head 120 of the other coupling element 100 is engaged with the engaging groove 130 at the other side of the body 110. Thereby effecting interdigitation of the fastener elements 100.

Referring to fig. 1-3, as an embodiment, the fastener element 100 further includes a connecting portion 150, and the connecting portion 150 is connected to an end of the body 110 away from the engaging head 120. In a specific application, the connecting portion 150 is connected to one end of the tooth body 110, and the connecting portion 150 is used for sewing the chain belt to fix the fastener element 100 to the chain belt. The connecting portion 150 has a rectangular block shape, although the shape of the connecting portion 150 is not limited thereto in specific applications, and for example, the shape of the connecting portion 150 may be a semicircular shape or other shapes as an alternative. In the present embodiment, the connecting portion 150 and the tooth body 110 may be integrally formed, or may be separately provided and connected. Further, the connection part 150 may be provided with a through hole through which a suture is connected with the connection part 150 when suturing. Of course, in a specific application, the connection part 150 is not limited to the chain belt, and for example, the connection part 150 may be fixed on the chain belt by gluing as an alternative. Meanwhile, the width of the connecting portion 150 in the second direction is smaller than that of the tooth profile 110, that is, the connecting portion 150 is protruded from the outer surface of the tooth profile 110 to be extended into the engaging groove 130.

Referring to fig. 1-3, as an embodiment, the direction of the body 110 toward the engaging head 120 is a second direction, the first direction is perpendicular to the second direction, and the cross section of the engaging head 120 along the second direction is an ellipse, and the cross section of the ellipse is gradually reduced from the center of the engaging head 120 to both sides of the second direction. In a specific application, in order to prevent the fracture separation of the engaging head and the tooth body 110, the cross section of the engaging head 120 along the second direction is elliptical, the elliptical engaging head 120 is not only beneficial to improving the connection strength between the engaging head 120 and the tooth body 110, but also smoother entering or leaving of the elliptical contact surface and the engaging groove 130, and avoiding the friction loss between the engaging head 120 and the engaging groove 130.

Referring to fig. 1 to 3, as an embodiment, a cross section of the engagement groove 130 along the second direction is arc-shaped, and the cross section of the arc-shaped is gradually reduced from the center of the engagement groove 130 to both sides of the second direction. In a specific application, in order to prevent the fatigue crack from occurring on the engaging groove 130, the cross section of the engaging groove 130 is gradually reduced from the center of the engaging groove 130 to both sides of the second direction, and the contact surface of the engaging groove 130 is smooth, which is beneficial to avoiding the problem of friction loss of the engaging head 120 caused by the unevenness of the surface of the engaging groove 130, thereby avoiding affecting the degree of convenience of the engagement of the fastener elements 100 of the slide fastener 200.

Referring to fig. 1 to 3, as an embodiment, the engaging groove 130 is formed along a third direction, the first direction, the second direction and the third direction are perpendicular to each other, and the engaging groove 130 extends through the tooth body 110 along the third direction. In specific application, the first direction, the second direction and the third direction are combined to form a three-axis coordinate system, the engaging groove 130 penetrates through the tooth body 110, so that the engaging groove 130 and the engaging head 120 can be engaged and rotated better, and meanwhile, the structure with the engaging groove 130 is also beneficial to processing.

Referring to fig. 1 to 3, as an embodiment, the engaging head 120 has a width in the third direction smaller than that of the body 110. In a specific application, the width of the engaging head 120 is smaller than that of the tooth body 110, such a structure design is beneficial to protecting the engaging head 120, and since the engaging head 120 is matched with the engaging groove 130, abrasion is difficult to avoid during use, therefore, the width of the engaging head 120 is set to be smaller than that of the tooth body 110, such a structure is beneficial to protecting the engaging head 120 to a certain extent, so that abrasion of the engaging head 120 is reduced as much as possible during use of the slide fastener 200 by a user.

Referring to fig. 4, a second object of the present invention is to provide a zipper 200. The slide fastener 200 is a coupling member for coupling or separating articles by means of the coupling elements 100 arranged in series, and is now widely used for clothes, bags, tents, and the like.

Referring to fig. 4, a zipper 200 includes the above-mentioned fastener elements 100 and two fastener tapes. The plurality of elements 100 are sequentially arranged at an interval at one side edge of the fastener tapes, and the elements 100 on the two fastener tapes are oppositely arranged, so that the elements 100 on the two fastener tapes are engaged with each other to form the slide fastener 200. In specific application, when the fastener elements 100 on two fastener tapes are engaged with each other, the engaging head 120 of each fastener element 100 is clamped in the engaging groove 130 of another fastener element 100, so that the two fastener elements 100 which are oppositely arranged are engaged with each other at intervals along a first direction, and it is worth noting that the engagement at intervals between the fastener elements 100 can effectively improve the engagement resistance of the fastener elements 100, so that the fastener elements 100 are convenient to engage, and the engagement wear of the fastener elements 100 is reduced, and meanwhile, the thickness of the tooth body 110 is greater than that of the engaging head 120, so that the interval between two adjacent fastener elements 100 in the process of engaging with each other of the fastener elements 100 is further ensured, and meanwhile, the increase in thickness of the tooth body 110 is also beneficial to enhancing the strength of the fastener elements 100, so that the fastener elements 100 are not easy to be damaged in the using process, and further the service life of the zipper 200 is prolonged. The material of the fastener element 100 may be a nylon material, a resin material, or a metal material.

Referring to fig. 4, as an embodiment, when two adjacent coupling elements 100 are coupled, a distance between an edge of the coupling head 120 and an edge of the coupling groove 130 is 0.15mm to 0.2mm. In a specific application, in order to make the coupling elements 100 smoothly engage at intervals and avoid the phenomenon of jamming of the engagement, the distance between the edge of the engaging head 120 and the edge of the engaging groove 130 is 0.15mm to 0.2mm, and preferably, the distance between the edge of the engaging head 120112 and the edge of the engaging groove 130 is 0.18mm.
