Abstract

The utility model discloses a zipper. The zipper comprises a pair of cloth straps, wherein the opposite side edges of the pair of cloth straps are respectively provided with a row of zipper teeth, the zipper teeth are fixed to the cloth straps through sewing threads, a puller which allows the two rows of zipper teeth to be meshed with or separated from each other is arranged between the two rows of zipper teeth, and an upper stopping piece and a lower stopping piece are arranged on the portion, at the upper endpoint of each row of zipper teeth, of each cloth strap and on the portion, at the lower endpoint of each row of zipper teeth, of each cloth strap respectively. Each zipper tooth is of an arc-shaped structure, the zipper teeth are fixed to the cloth straps in a unified and inclined mode, each zipper tooth connection point on one of the cloth straps is higher than each free point on the one of the cloth straps, and each zipper tooth connecting point on the other cloth strap is lower than each free point on the other cloth strap, namely, every two zipper teeth which are meshed with each other and arranged on the different cloth straps are also arranged in an inclined mode. Due to the fact that every two zipper teeth which are meshed with each other and arranged on the different cloth straps are arranged in the inclined mode, after every two zipper teeth are meshed with each other, the whole zipper has the spiral effect and can meet the requirement for combining fabrics in peculiar shapes such as inclined shapes and spiral shapes, and folded shapes, twisted shapes and the like can not appear in the combination positions of the fabrics.

Description

Slide fastener

Technical field

The utility model relates to the slide fastener technical field, more specifically says a kind of slide fastener that has spiral effect after engagement.

Background technology

Slide fastener, rely on continuously arranged chain tooth, and the connector that makes fabric and close or separate is existing in a large number for clothes, bag, tent etc.Structure is as follows: comprise a pair of strap, on this edge of opposite side to strap, row are provided with a row chain tooth respectively, the chain tooth is fixed on strap by sewing thread, be provided with the pull head that makes their engagements and separate between two row chain teeth, be respectively arranged with only part and lower only part on the strap of the upper and lower end points of every row chain tooth.

At present, slide fastener coupling element homogeneity on the market is vertical connection with strap, be that the tie point level of each the chain tooth on strap is in its free point, such slide fastener is after engagement, whole piece cloth zone face is smooth, so the slide fastener that we see is be applied to the fabric linear pattern and close or separate basically.Yet, along with the product category become increasingly abundant on market, the fabric of the peculiar forms such as some are oblique, spiral the demand appearance of closing or separating, the only single linear pattern of conventional zipper just can not satisfy the demands, even reluctantly by linear pattern and close or the conventional zipper of separating is applied up, and the place of closing just there will be the form of fabric crease, distortion, very ugly.

The utility model content

The purpose of this utility model is to overcome the above defect of prior art, a kind of spiral effect that has after engagement is provided, can cater to the fabric of the peculiar forms such as some are oblique, spiral the demand of closing, and the place of closing not there will be the slide fastener of the forms such as fabric crease, distortion.

In order to reach above purpose, the utility model is achieved through the following technical solutions: a kind of slide fastener, comprise a pair of strap, on this edge of opposite side to strap, row are provided with a row chain tooth respectively, the chain tooth is fixed on strap by sewing thread, be provided with the pull head that makes their engagements and separate between two row chain teeth, be respectively arranged with only part and lower only part on the strap of the upper and lower end points of every row chain tooth; It is characterized in that, the shape of described chain tooth is convex structure, and the fixing mode unification on strap of each chain tooth is oblique layout, wherein each the chain tooth tie point on a strap is higher than free point, each chain tooth tie point on another strap is just lower than free point, and two chain teeth on different straps of the engagement that matches also are oblique layout.

The utility model match the engagement two chain teeth on different straps be oblique layout, after engagement, whole slide fastener has spiral effect, can cater to the fabric of the peculiar forms such as some are oblique, spiral the demand of closing, and the place of closing not there will be the slide fastener of the forms such as fabric crease, distortion.

As preferably, pull head comprises slip lid, lower sliding cover, guide pillar and pulling-on piece, upper slip lid and lower sliding cover are connected in one by guide pillar and hollow is formed with the teeth cavity of taking in the chain tooth, and pulling-on piece is hinged on slip lid, and the jointed shaft cross section that pulling-on piece is hinged on slip lid is rectangle; Be provided with the window of interior logical teeth cavity on upper slip lid, be provided with a shell fragment in window, shell fragment one end is fixed on slip lid, on shell fragment other end free end, is provided with latch, the shell fragment middle part is pressed against on the jointed shaft of pulling-on piece, and in the rotation process of jointed shaft, latch can stretch into and stretch out inside and outside teeth cavity.

When pulling-on piece fits in upper slip lid end face, now the shell fragment middle part is pressed against on the narrow limit of jointed shaft, and latch extend in teeth cavity under the pressure-acting of shell fragment, embeds in two chain teeth of engagement, plays the effect that pull head is lived in location.When pulling-on piece is peeled off upper slip lid end face, now the shell fragment middle part is pressed against on the broadside of jointed shaft, and shell fragment is backed down, and latch just stretches out outside teeth cavity, and now pull head is in free state.

As preferably, be connected with an axle sleeve freely rotated on the free end of pulling-on piece, the axis of axle sleeve and pulling-on piece length direction are perpendicular.

We in the process zipped along with the difference of height, the adjustment that will adapt of the gradient of pulling-on piece, between two fingers of kneading pulling-on piece, also just adjust thereupon, active force between pulling-on piece refers to for a side can increase gradually, active force between opposite side refers to reduces gradually, thereby there will be impression between referring to, refer to that sense is very uncomfortable, therefore the utility model has been set up an axle sleeve at the free end of pulling-on piece, it can keep the adjustment of pulling-on piece gradient in slide fastener moves, can keep again constant to active force between two fingers of kneading, make and refer to that sense is comfortable.

As preferably, the both side edges opposite position of upper slip lid and lower sliding cover is provided with extended upper flange and lower flange laterally respectively, and upper flange and lower flange are the strap end face and parallel.

Often there will be the fabric that clips to the strap both sides in the process zipped at us, then block pull head, at this moment will be by pull head slippage being difficult for very out, serious consequence is pulled out openning by fabric exactly, for this situation, the utility model sums up the reason that fabric sandwiched by pull head: also there is embeddable gap (this gap is inevitable) in foreign aid side entrance that slip lid and lower sliding cover contraposition are gone up in the pull head both sides after taking in strap, the utility model is provided with flange at this place, make the entrance in this gap obtain obstruction, so fabric just is not easy to sandwich, played protective effect.

Beneficial effect: the utility model match the engagement two chain teeth on different straps be oblique layout, after engagement, whole slide fastener has spiral effect, can cater to the fabric of the peculiar forms such as some are oblique, spiral the demand of closing, and the place of closing not there will be the slide fastener of the forms such as fabric crease, distortion.
