Description
Technical field
The utility model relates to zipper technology field, particularly relates to a kind of Anti-breakage zipper and chain thereof.
Background technology
Slide fastener, as one locking connecting elements efficiently, the product such as clothes, case and bag is applied extremely extensive.
Slide fastener mainly comprises left chain, right chain and pull head, the corresponding snap close of left and right chain is closed or corresponding unblock separation by the effect of pull head.And left chain or right chain structure are symmetrical, include chain band and chain denture, chain denture is made on chain band by suture.The suture of existing slide fastener is all cooperatively interacted by a foundation line and two upper threads and forms, by bottom line formed multiple continuous print collar respectively corresponding cover share upper thread and form noose, and then form the suture texture of chain-type stitch.
Because suture only has two upper threads, it is very limited to the fixed effect of chain denture, and slide fastener is in moving process repeatedly, or when being subject to external force extruding, often easily there is sprocket dislocation, and cause slide fastener bursts, and the something lost of property in case and bag can be caused to fall or stolen.
For solving above-mentioned slide fastener easily by problem that is damaged, that pop, industry is proposed double-layered slide fastener product, although this double-layered slide fastener product can solve slide fastener preferably easily damage the defect of tearing, it obviously brings the defect that product weight increases.This is very great for impact case and bag, in the transport services such as aviation, the baggage wieight that often can freely carry passenger has strict restriction, if case and bag cause own wt to increase because adopting double-layered slide fastener, the portable effective baggage wieight of passenger must will be made to reduce, and the baggage fee that passenger may be caused to have to pay great number is used.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of chain of Anti-breakage zipper, has better Anti-breakage performance, and lightweight.
The further technical problem to be solved of the utility model provides a kind of Anti-breakage zipper, has better Anti-breakage performance, and lightweight.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of chain of Anti-breakage zipper, comprise chain band and make the chain denture on described chain band by means of suture, described suture comprises at least two foundation lines and at least two upper threads, and described each foundation line is the corresponding and at least one upper thread chain-type stitch that coordinates the quantity that forms noose and quantity of formation and bottom line identical respectively.
Further, described chain denture has multiple sprocket, and the end face of each sprocket is also provided with at least one for holding and spacing described sutural groove.
Further, described suture is sewed up in the corresponding mode of entangling a upper thread of each foundation line and forms chain-type stitch.
Further, described suture is sewed up in the corresponding mode of entangling two upper threads of each foundation line and forms chain-type stitch.
Further, described chain includes two groups of sutures, wherein first group of suture is sewed up in the corresponding mode of entangling a upper thread of each foundation line and forms chain-type stitch, and second group of suture is then sewed up in the corresponding mode of entangling two upper threads of each foundation line and form chain-type stitch.
Further, described sprocket is classified as the wormlike chain denture that resin is made, and it has multiple sprocket.
On the other hand, the utility model also provides a kind of Anti-breakage zipper, the pull head comprising the left chain of the snap close connection that can cooperatively interact, right chain and impel left chain and right chain to coordinate snap close to be connected or to be separated, described left chain and right chain are the chain as above described in any one.
The beneficial effects of the utility model are: by arranging at least two foundation lines and at least two upper threads, and the chain-type stitch that quantity of formation is identical with bottom line quantity, thus can be fixed from multiple spot chain denture, the fixed effect of chain denture is better, effectively can avoid slide fastener bursts; And hold and spacing suture by also arranging corresponding groove on chain denture, each chain dental transition is not easily moved relative to suture, can play better fixed effect.

Detailed description of the invention
In order to more clearly set forth the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1 and Fig. 2, the utility model provides a kind of Anti-breakage zipper, and it comprises left chain 1, right chain 2 and pull head 3, by the effect of pull head 3, impels left chain 1, right chain 2 cooperatively interacts snap close connection or unlock separation.
Left chain 1 and the right chain 2 of the utility model Anti-breakage zipper are symmetrical arranged, but structural principle is identical, namely specifically describes its structure for left chain below.
Described left chain 1 comprises chain band 10 and makes the chain denture 12 on described chain band 10 by means of suture 14, described suture 14 comprises at least two foundation line 140 and at least two foundation lines 142, and described each foundation line 140 is corresponding and at least one upper thread 142 chain-type stitch that coordinates the quantity that forms noose and quantity of formation and bottom line 140 identical respectively.Described chain denture 12 has multiple sprocket, preferably adopts the wormlike chain denture be made of resin, such as: nylon chain denture.
For playing better locating effect, at least one can also be also provided with for holding and spacing described sutural groove 120 further at the end face of each sprocket of described chain denture 12, described groove 120 can be a big groove, all sutures are all contained in same groove (as shown in Figure 3), also can be that a groove is set for each foundation line, hold corresponding suture (as shown in Figure 4, Figure 5) respectively.
Sutural setting of the present utility model can have multiple different embodiment:
Mode one, the mode that described suture 14 entangles two upper threads 142 with each foundation line 140 correspondence is sewed up and forms chain-type stitch, as shown in Figure 3.
Mode two: the mode that described suture 14 entangles a upper thread 142 with each foundation line 140 correspondence is sewed up and forms chain-type stitch, as shown in Figure 4.
Mode three is the combination of above two kinds of modes, that is: the mode that first group of suture 14 entangles a upper thread 142 with each foundation line 140 correspondence is sewed up and forms chain-type stitch, the mode that second group of suture then entangles two upper threads 142 with each foundation line 140 correspondence is sewed up and forms chain-type stitch, as shown in Figure 5.
Be understandable that, sutural quantity can also be more, such as: the quantity of bottom line, upper thread all can be set to 3,4,8, even more.
The utility model is by arranging at least two foundation lines 140 and at least two upper threads 142, and the chain-type stitch that quantity of formation is identical with bottom line 140 quantity, thus can be fixed from multiple spot chain denture 12, the fixed effect of chain denture 12 is better, effectively can avoid slide fastener bursts.And hold and spacing suture 14 by also arranging corresponding groove 120 on chain denture 12, each chain dental transition of chain denture 12 is not easily moved relative to suture 14, can play better fixed effect.
Be only several specific embodiment of the present utility model above, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
