The utility model discloses the optimum proportion of neck and trunk on the preferred zipper tooth to improve the reliability of being connected between neck and the meshing head, can keep the rigidity of zip fastener, can keep the zip fastener to use crooked flexibility again.
Description
Technical Field
The utility model relates to a zip fastener technical field, the more specifically waterproof zip fastener that says so.
Background
Waterproof zipper, including a pair of chain belt of following their length direction amalgamation side by side, the chain belt is provided with the chain tooth of following its length direction clearance arrangement at the amalgamation end edge, the chain belt end edge of chain tooth installation each other in close contact with each other when the chain tooth meshing, the chain tooth has table tooth and back of the body tooth at chain belt amalgamation end edge table back integrated into one piece, have on the chain belt and allow the perforating hole that the connecting portion that table tooth and back of the body tooth meet passed through, table tooth and back of the body tooth include meshing head, neck and trunk portion.
In practice, the inventor finds that if the proportion is too large, the neck part is too thin, the head part is easy to deform and damage in the using process, and the rigidity is reduced; conversely, if the ratio is too small, the neck part is too thick, the bending property of the zipper is limited, and the zipper is too stiff to bend.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the above defect of prior art, provide one kind and can keep the rigidity of zip fastener, can keep the waterproof zip fastener of zip fastener use crooked flexibility again.
In order to achieve the above purpose, the utility model discloses a realize through following technical scheme: a waterproof zipper comprises a pair of chain belts spliced side by side along the length direction of the chain belts, wherein the chain belts are provided with chain teeth arranged at intervals along the length direction at spliced end edges, the opposite chain belt end surfaces of the chain belt end edges installed on the chain teeth are mutually and tightly contacted when the chain teeth are meshed, the chain teeth comprise surface teeth and back teeth which are integrally formed at the front and back parts of the spliced end edges of the chain belts, the chain belts are provided with through holes for allowing connecting parts connected with the surface teeth and the back teeth to pass through, and the surface teeth and the back teeth comprise meshed head parts, neck parts and main parts.
The utility model discloses the optimum proportion of neck and trunk on the preferred zipper tooth to improve the reliability of being connected between neck and the meshing head, can keep the rigidity of zip fastener, can keep the zip fastener to use crooked flexibility again.
Preferably, a connecting head with a thickness larger than that of the chain belt is arranged on the end edge of the chain belt mounted with the chain teeth.
The utility model discloses set up the connector that thickness is greater than chain belt self at the chain belt end edge of chain tooth installation, make two chain belt terminal surfaces each other in close contact with's contact surface increase to guarantee to distort at will on its length direction and still can keep its gas tightness and water proofness.
Preferably, the through hole is a square hole, and a portion of the connecting portion passing through the through hole is a square shaft.
In the process of engaging and disengaging the zipper head with the zipper teeth, a lateral impact force is given to the zipper teeth, the surface teeth and the back teeth of the zipper teeth are fixed in the through holes of the zipper belt only through the connecting parts, the zipper teeth are easily twisted and damaged in the fixing mode, the through holes are designed into square holes, and the parts of the connecting parts passing through the through holes are square shafts, so that the lateral impact force resistance of the zipper teeth can be effectively improved, and the fixing strength of the zipper teeth is improved.
Preferably, the surface teeth and the back teeth are respectively provided with a groove on the exposed end surface within the front and back projection range of the chain belt.
The surface and the exposed end surface of the back tooth main body part are provided with grooves, so that the contact area between the surface and the zipper puller can be reduced, and the contact friction between the surface and the zipper puller is further reduced, and the smoothness of the zipper puller passing through the contact area is ensured.
Has the advantages that: the utility model discloses the optimum proportion of neck and trunk on the preferred zipper tooth to improve the reliability of being connected between neck and the meshing head, can keep the rigidity of zip fastener, can keep the zip fastener to use crooked flexibility again.

Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the single chain belt of the present invention.
In the figure: 1-chain belt, 2-chain teeth, 3-surface teeth, 4-back teeth, 5-through holes, 6-grooves and 7-connectors.
Detailed Description
In order to make the technical means, the creation features and the achievement objects of the present invention easy to understand, the present invention will be further explained with reference to the specific embodiments.
Example (b): as shown in fig. 1 and 2, a waterproof slide fastener includes a pair of fastener tapes 1 spliced side by side along their length direction, the fastener tapes 1 are provided at spliced end edges with fastener elements 2 arranged intermittently along their length direction, and the fastener tape end surfaces facing each other at the end edges where the fastener elements 2 are attached are brought into close contact with each other when the fastener elements are engaged. The end edge of the chain belt mounted with the chain teeth is provided with a connector 7 with the thickness larger than that of the chain belt.
The chain teeth 2 are provided with a front tooth 3 and a back tooth 4 which are integrally formed at the front and back parts of the spliced end edge of the chain belt 1, the chain belt 1 is provided with a through hole 5 for allowing the connection part connected with the front tooth 3 and the back tooth 4 to pass through, the through hole 5 is a square hole, the part of the connection part passing through the through hole 5 is a square shaft, and the front tooth 3 and the back tooth 4 are respectively provided with a groove 6 on the exposed end surface in the front and back projection range of the chain belt 1.
