Moreover, the terms first, second, etc. are only used to distinguish a plurality of components or structures having the same or similar structure, and do not denote any particular limitation on the arrangement order or connection relationship.
Referring to fig. 1, an embodiment of the present application provides an explosion-proof zipper 200, including: a left chain 210, a right chain 220, and a slider (not shown). The left chain 210 and the right chain 220 can be mutually matched and connected in a locking way, and the pull head can enable the left chain 210 and the right chain 220 to be matched and connected or separated in a locking way.
The left chain 210 and the right chain 220 of the anti-explosion zipper 200 in the embodiment of the application are symmetrically arranged, but the structural principles are the same, and the anti-explosion chain 100 is specifically described below.
Example 1
Referring to fig. 2 and 3, an explosion-proof chain 100 according to an embodiment of the present application includes: a chain belt 1, an outer sprocket row 2, an inner sprocket row 3 and a protective belt 4. Wherein, the chain belt 1 is a cloth belt, and the materials of the chain belt can be terylene, nylon, cotton and the like; the outer sprocket row 2 is positioned on the upper side of the chain belt 1, the inner sprocket row 3 is positioned on the lower side of the chain belt 1, and the protecting belt 4 is positioned on the side of the outer sprocket row 2 away from the chain belt 1; the outer sprocket row 2, the inner sprocket row 3 and the protective tape 4 are sewn to the chain tape 1 by a sewing thread 5.
In this way, the outer sprocket row 2 can avoid exposing on the surface of the box or bag, so that the damage to the sprocket in the outer sprocket row 2 caused by direct collision and scraping of foreign objects can be reduced, and in addition, the friction and abrasion between the outer sprocket row 2 and the inner wall of the slider are correspondingly reduced in the process of repeatedly opening and closing the zipper by the slider. Thus, the teeth of the anti-explosion chain 100 are not easily worn, so that the anti-explosion chain has the advantages of being not easily worn by the suture lines and the teeth and being good in anti-explosion performance, and further the anti-explosion zipper 200 has the advantage of being not easily exploded.
Alternatively, in the present embodiment, the outer element row 2 and the inner element row 3 have a plurality of elements, alternatively, helical element rows made of resin, for example: nylon sprocket row. The protective tape 4 may be made of the same material and color as the fastener tape 1. Thus, the entire explosion-proof chain 100 is more beautiful. When the protective belt 4 is also made of a cloth belt, the cloth belt is made of a flexible material, and the cloth belt is tightly tied on the surface of the outer sprocket row 2 under the fixation of the suture 5, so that the fixing position of the protective belt 4 is concave relative to the upper surface of the protective belt 4, and the inner wall of the slider is not in direct contact with the suture 5 in the process of repeatedly opening and closing the zipper by the slider, so that the abrasion of the suture 5 is avoided, the burst of the sprocket row due to the abrasion of the suture 5 is avoided, and the service life of the burst-proof chain 100 is prolonged. Of course, the protecting belt 4 may be a hard paillette belt, so that the appearance of the anti-explosion chain 100 can be further improved.
In order to make the sewing thread 5 more accurately sew the protecting belt 4, the outer sprocket row 2, the inner sprocket row 3 and the chain belt 1, no needle jump occurs. Preferably, referring to fig. 4, in the present embodiment, the protecting strip 4 includes a first side 41 and a second side 42 disposed in parallel, and connecting sides 43 disposed at uniform intervals and having one end connected to the first side 41 and the other end connected to the second side 42, wherein the distance between two adjacent connecting sides 43 is equal to the tooth pitch of adjacent teeth in the outer teeth row 2. So, two adjacent connection limit 43 equidistance just equals the tooth pitch of adjacent sprocket, and is formed with the suture hole a that supplies suture 5 to pass between two adjacent connection limit 43, when suture 5 was made the protective tape 4 in outer sprocket row 2 upside, its cooperation was more accurate, the condition of jump needle can not appear, and can not lead to protective tape 4 to warp because of suture 5 makes up the extrusion, influences explosion-proof chain 100's roughness.
In order to further enhance the fixing effect of the sewing thread 5 to the protecting band 4, the outer sprocket row 2 and the inner sprocket row 3, it is preferable that the sewing thread 5 includes at least two base threads 51 and at least two upper threads 52, and each base thread 51 forms the same number of chain stitches as the base threads 51 in correspondence with the cooperation of at least one upper thread 52 to form a loop. As shown in fig. 3, in the present embodiment, the sewing thread 5 includes two base threads 51 and two upper threads 52, and each base thread 51 forms a loop corresponding to one upper thread 52 to form the same number of chain stitches as the base threads 51. Of course, the sewing threads 5 may be sewn to form chain stitches in such a manner that each base thread 51 is sleeved with two upper threads 52. There is no particular limitation herein.
It will be appreciated that the number of sutures 5 may also be greater, for example: the number of the bottom threads 51 and the upper threads 52 can be set to 3, 4, 8 or even more.
In order to avoid interference of the plurality of sewing threads 5 in the sewing process, the sewing accuracy is improved, and the strength of the protecting belt 4 is improved. Preferably, as shown in fig. 4, a separation edge 44 separating the suture 5 is provided between the first side 41 and the second side 42.
In order to avoid the protective tape 4 from affecting the lock connection or separation of the explosion-proof slide fastener 200, the width of the protective tape 4 is smaller than or equal to the width of the outer element row 2 and/or the inner element row 3. Thus, the lock connection or separation process of the explosion-proof zipper 200 can be smoother.
Example two
This embodiment is substantially identical to the first embodiment except that the protective strip 4 is located on the side of the inner row of teeth 3 facing away from the chain belt 1. In this way, the inner element row 3 in the explosion-proof chain 100 can be prevented from directly facing the articles in the case or bag, that is, collision and friction between the elements in the inner element row 3 and the articles can be reduced, and in addition, friction between the inner element row 3 and the inner wall of the slider can be reduced in the process of repeatedly opening and closing the zipper by the slider. This makes the explosion-proof chain 100 have the advantages of less wear of the sprocket, less damage, and less explosion.
Example III
The present embodiment is substantially the same as the first embodiment except that the protective tape 4 is located on the protective tape 4 on the side of the outer and inner rows of teeth 2, 3 facing away from the chain belt 1. So arranged, it has all the advantages of the first and second embodiments, and has better explosion-proof performance.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
