Embodiment approach 1

[0046] image 3 are four views of the fastener element in the first embodiment of the present invention, where image 3 (a) is a stereogram, image 3 (b) is the main view, image 3 (c) is a top view, image 3 (d) is a right view. The fastener element 2 of the first embodiment includes a body portion 21 , a mounting portion 22 , a neck portion 23 and a head portion 24 . The body part 21 includes an upper body part 211 and a lower body part 212 . The mounting part 22 is used for setting the tape of the zipper, and the neck part 23 connects the main body part 21 and the head part 24 .

[0047] At least one of the upper body portion 211 and the lower body portion 212 of the fastener element 2 includes a convex portion 25 and a base portion 28, the convex portion 25 extends from the base portion 28, and the convex portion 25 is located in the middle of the chain element 2 in the front-rear direction And extend along the left-right direction of chain tooth 2. for figure 2 T...

Embodiment approach 2

[0053] Figure 4 are five views of the fastener element in the second embodiment of the present invention, where Figure 4 (a) is a stereogram, Figure 4 (b) is the main view, Figure 4 (c) is a top view, Figure 4 (d) is the right view, Figure 4 (e) is a left view. The following will focus on the points different from the first embodiment, and the description of the same parts as the first embodiment will be omitted.

[0054] The element 2 in the second embodiment also has the convex part 25 and the inclined part 26 similarly to the first embodiment. In the fastener element 2 in the second embodiment, the protrusion 27 is added to the first embodiment. Preferably, the protrusions 27 are symmetrically formed on both sides of the protrusion 25 in the front-rear direction of the fastener element 2 . Further preferably, the centerline of the protruding portion 27 is consistent with the centerline of the mounting portion 22 of the fastener element 2 in the vertical directi...

Abstract

The invention provides a chain tooth, a chain strap and a zipper. The chain tooth and a strap are arranged together to form the chain strap, and the chain tooth comprises a body part, a mounting part,a neck part and a head part. The body part and the head part are connected through the neck part, the mounting part is used for mounting of the strap, the body part comprises an upper body part and alower body part, and at least one of the upper body part and the lower body part comprises a protruding part and a base part. The protruding part extends out of the base part, is located in the middle in the front-back direction and extends in the left-right direction. Furthermore, an inclined part inclined downwards in the left-right direction is formed on at least one side, in the vertical direction, of the head part, and convex parts extending in the front-back direction are formed on the two sides of the protruding part. According to the chain tooth, the chain strap and the zipper, weightreduction can be achieved, and strength and use reliability can be guaranteed.

Description

technical field [0001] The invention relates to a fastener element and a chain belt and a slide fastener made of the fastener element. Background technique [0002] Zippers are widely used in all kinds of clothing. Resin zippers are lighter in weight than metal zippers, so they are widely used in occasions that require lightweight. [0003] figure 1 is an overall schematic diagram of a conventional zipper, showing a conventional zipper 100 including a belt 10 , chain elements 20 and a slider 30 . The belt 10 and the fastener elements 20 are arranged together to constitute a chain belt. figure 2 are four views of the teeth 20 in the existing zipper, where figure 2 (a) is a stereogram, figure 2 (b) is the main view, figure 2 (c) is a top view, figure 2 (d) is a right view. The fastener element 20 includes a body portion 201 , a mounting portion 202 , a neck portion 203 and a head portion 204 . The main body part 201 includes an upper main body part 2011 and a lowe...
