Problems solved by technology

[0002] Today's zippers have two toothed belts, each with a row of chain teeth, and the two rows of chain teeth are arranged alternately. The teeth engage or disengage from each other. The action of engaging or disengaging is accomplished by applying lateral pressure on both sides of the chain teeth by the zipper head. Therefore, during the process of engaging or disengaging, there is a lot of friction between the two rows of chain teeth. As a result, the two rows of chain teeth make noise during the process of meshing or disengaging, so that today's zippers cannot be used in related technical industries

Embodiment 1

[0026] like figure 1 and figure 2 As shown, a zipper includes two toothed belts and a zipper head 2 corresponding to the toothed belt. The toothed belt is composed of a cloth belt 11 and a tooth row 12 arranged on the working side of the cloth belt. The zipper head 2 is provided with Two adjacent dentition passages 21, one end of the two dentition passages 21 are connected to form a tightening passage, and the other ends of the two dentition passages 21 are corresponding limiting passages corresponding to the dentition 12; and the zipper head 2 includes an upper splint 23, a lower splint 24, a connecting block 5 and a pull pendant 25, the pull hanger 25 is arranged on the top of the upper splint 23, the upper splint 1 is fixedly connected with the lower splint 24 through the connecting block 5, and the two dentition channels 21 Set in connection block 5.

Embodiment 2

[0031] like image 3 and Figure 4 As shown, compared with Embodiment 1, the difference is that the two tooth row channels 21 are formed by the smooth transition from the tooth-entry end of the limiting channel to the tightening channel, and the rest are the same as in Embodiment 1. There is no special limitation here, and they all belong to the protection scope of the present invention. Its mechanism of action is also the same as in Example 1, so it will not be repeated here.

Embodiment 3

[0033] like Figure 5 and Figure 6 As shown, compared with Embodiment 1, the difference is that one of the passages 21 is a linear passage, and the other tooth row passage 21 is formed by a smooth transition from the inlet end of the limiting passage to the tightening passage, The rest are the same as in Embodiment 1, and are not particularly limited here, and all belong to the protection scope of the present invention. Its mechanism of action is also the same as in Example 1, so it will not be repeated here.

Abstract

The invention discloses a zipper, which comprises two toothed tapes and a slider corresponding to the toothed tapes; each toothed tape consists of a cloth tape and a row of teeth arranged on the working side of the cloth tape; the slider is internally provided with two adjacent tooth passages; one end of one tooth passage and one end of the other tooth passage are communicated and connected with each other to form a closing passage; the other ends of the two tooth passages are both limiting passages corresponding to the two rows of teeth; the height from the bottom surface of the inner side of the tooth inlet end of the limiting passage of one tooth passage to the bottom of the slider is no smaller than the height from the top surface of the inner side of the tooth inlet end of the limiting passage of the other tooth passage to the bottom of the slider. The original engagement or disengagement action which is performed by exerting transverse pressure upon two sides of the teeth by the slider is changed into an action which is performed by exerting longitudinal pressure upon two sides of the teeth by the slider, thus, the friction between two rows of teeth is fundamentally reduced, the service life of the zipper is prolonged, and no noise is produced in the engagement or disengagement action process.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a zipper that emits no noise. Background technique [0002] Today's zippers have two tooth belts, each with a row of chain teeth, and the two rows of chain teeth are arranged alternately. The teeth engage or disengage from each other. The action of engaging or disengaging is accomplished by applying lateral pressure on both sides of the chain teeth by the zipper head. Therefore, during the process of engaging or disengaging, there is a lot of friction between the two rows of chain teeth. Thereby causing the two rows of chain teeth to emit noise during engagement or disengagement, so that the current slide fastener cannot be applied to related technical industries. Contents of the invention [0003] In order to solve the above technical problems, we propose a zipper, the purpose of which is to emit no noise during the process of engaging or disengaging, the friction between the...
