[0001] The present application claims priority to the Chinese patent application No. 202410831003.3, filed on June 25, 2024, and entitled "Anti-explosion sub chain, anti-explosion slide chain and clothing", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of clothing accessory manufacturing, in particular to an anti-explosion sub chain, an anti-explosion slide chain and clothing. BACKGROUND

[0003] The existing slide chain usually includes a sub chain and a mother chain, the mother chain is provided with a tooth cavity, and the sub chain is provided with a tooth part corresponding to the tooth cavity. The relative movement between the mother chain and the sub chain is realized by the tooth part of the sub chain sliding in the tooth cavity of the mother chain. Now a large number of slide chains are used in clothing, packaging, pockets, tents, etc., and the tooth of the sub chain usually slides in the tooth cavity of the mother chain. However, in the prior art, when the sub chain of the slide chain is transported, it will be bent along the thickness direction of the cloth belt. At this time, the tooth of the sub chain will collide and be forced to extrude, and the tooth may be broken, i.e., the tooth will be damaged.

[0004] Therefore, how to avoid the sub chain from being broken when the slide chain is bent along the thickness direction of the cloth belt is a technical problem to be solved by those skilled in the art. SUMMARY

[0005] The present application aims to provide an anti-explosion sub chain which can avoid the sub chain from being broken when the slide chain is bent along the thickness direction of the cloth belt. The present application also provides an anti-explosion slide chain comprising the anti-explosion sub chain and a clothing comprising the anti-explosion slide chain.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0007] An anti-explosion sub chain comprises: a plurality of sub piece teeth arranged at intervals, the sub piece teeth comprising first teeth and second teeth arranged alternately, the first teeth and the second teeth each comprising a tooth base and a connecting part arranged on the tooth base, the connecting part dividing the tooth base into a first tooth base and a second tooth base, the first teeth further comprising a first protruding part above the first tooth base and connected to the end of the connecting part, and the second teeth further comprising a second protruding part above the second tooth base and connected to the end of the connecting part.

[0008] Preferably, the tooth base is provided with grooves on both sides in the first direction for mounting the cloth belt.

[0009] Preferably, the tooth base is provided with chamfers on both sides in the second direction.

[0010] As preferred, the connecting part is arranged on the sub-implant base on the symmetry axis in the second direction, and the lengths of the first protruding part and the second protruding part in the second direction match the connecting part;

[0011] The connecting part is perpendicular to the upper surface of the sub-implant base, and the connecting part is also perpendicular to the first protruding part and the second protruding part.

[0012] As preferred, the two side edges of the first protruding part and the second protruding part in the second direction are provided with arc-shaped guide surfaces.

[0013] As preferred, the two ends of the first protruding part and the second protruding part in the second direction are provided with extension parts, the extension parts of the two adjacent sub-implant teeth abut against each other, and the abutting surfaces are smooth arc-shaped surfaces.

[0014] As preferred, the sub-implant teeth are integrally formed by injection molding.

[0015] As preferred, the proportion of the gap between the two adjacent sub-implant teeth relative to the length of the sub-implant teeth in the second direction is specifically between 1 / 5 and 1 / 3.

[0016] An explosion-proof sliding chain, comprising a female chain, and further comprising the explosion-proof sub-chain of any one of the above.

[0017] A garment, comprising the explosion-proof sliding chain as described above.

[0018] With respect to the above background technology, the explosion-proof sub-chain provided by the present application comprises: a plurality of sub-implant teeth arranged at intervals, the sub-implant teeth comprising first teeth and second teeth arranged alternately, the first teeth and the second teeth each comprising a sub-implant base and a connecting part arranged on the sub-implant base, the connecting part dividing the sub-implant base into a first sub-implant base and a second sub-implant base, the first tooth further comprising a first protruding part located above the first sub-implant base and connected to the end of the connecting part, and the second tooth further comprising a second protruding part located above the second sub-implant base and connected to the end of the connecting part.

[0019] Specifically, when the sub-chain composed of a plurality of sub-implant teeth is bent inward, i.e., when the first teeth and the second teeth of the sub-implant teeth are located inside the bending and the sub-implant bases are located outside the bending, at this time, the inner diameter of the bending will gradually decrease, and the first teeth and the second teeth will be squeezed inward. Since the first teeth and the second teeth are arranged alternately, the first protruding part on the first tooth will be squeezed to the back of the second protruding part on the second tooth when the first tooth is bent, and similarly, the second protruding part on the second tooth will be squeezed to the back of the first protruding part on the first tooth. In this way, the mutual squeezing of the teeth of the sub-implant teeth when they are bent inward can cause the explosion of the teeth, i.e., the damage of the teeth. BRIEF DESCRIPTION OF DRAWINGS

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.

[0028] In order to make the technical personnel in the art better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0029] In the description of the present application, it should be understood that the terms "upper", "lower", "end" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present application.

[0030] The purpose of the present application is to provide an anti-explosion sub-chain, which can avoid the sub-chain from being broken when the sliding chain is bent along the thickness direction of the belt.

[0031] It should be noted that the direction of X in the drawing is defined as the first direction, and the direction of Y is defined as the second direction, and the first direction and the second direction are perpendicular to each other.

[0032] To achieve the above object, the present application provides the following technical solutions.

[0033] Please refer to FIG. 1 and FIG. 2, the present embodiment provides an anti-explosion sub-chain, comprising: a plurality of sub-component teeth 100 arranged at intervals, the sub-component teeth 100 comprising first teeth 110 and second teeth 120 arranged alternately, the first teeth 110 and the second teeth 120 both comprising a sub-tooth base 130 and a connecting portion 140 arranged on the sub-tooth base 130, the connecting portion 140 dividing the sub-tooth base 130 into a first sub-tooth base 131 and a second sub-tooth base 132, the first teeth 110 further comprising a first protruding portion 150 located above the first sub-tooth base 131 and connected to the end of the connecting portion 140, and the second teeth 120 further comprising a second protruding portion 160 located above the second sub-tooth base 132 and connected to the end of the connecting portion 140.

[0034] Specifically as shown in FIG. 1 and FIG. 2, the sub-chain has two kinds of sub-component teeth 100, which are the first teeth 110 and the second teeth 120, and the sub-chain is composed of the first teeth 110 and the second teeth 120 alternately, the first teeth 110 and the second teeth 120 have the same overall shape, but the first protruding portion 150 of the first teeth 110 and the second protruding portion 160 of the second teeth 120 are oppositely arranged with the connecting portion 140 as the central axis, that is, the first protruding portion 150 and the second protruding portion 160 are reversely arranged in the first direction, as shown in FIG. 1, the first protruding portion 150 of the first teeth 110 protrudes away from the first direction, it should be noted that the side of the connecting portion 140 along the first direction is flush with the first protruding portion 150, that is, the end of the connecting portion 140 is provided with a protrusion on only one side, and by analogy, the second teeth 120 have the same overall shape as the first teeth 110, except that the second protruding portion 160 is arranged on the side of the connecting portion 140 facing the first direction, in this way, the first protruding portion 150 and the second protruding portion 160 are alternately arranged on both sides of the connecting portion 140 with the connecting portion 140 as the central axis; specifically, the first protruding portion 150 is located only above the first sub-tooth base 131, and the second protruding portion 160 is located only above the second sub-tooth base 132.

[0035] When the sub-chain composed of several sub-teeth 100 is bent inward, i.e. the first tooth 110 and the second tooth 120 of the sub-teeth 100 are located inside the bend, and the tooth base 130 is located outside the bend, as shown in the upper bend mode in FIG. 2. At this time, the inner diameter of the bend will gradually decrease, and the first tooth 110 and the second tooth 120 will be squeezed inward. Since the first tooth 110 and the second tooth 120 are staggered, the first protrusion 150 on the first tooth 110 will be squeezed to the back of the second protrusion 160 on the second tooth 120 when the sub-chain is bent. Similarly, the second protrusion 160 on the second tooth 120 will be squeezed to the back of the first protrusion 150 on the first tooth 110. In this way, the sub-teeth 100 can be squeezed when the sub-chain is bent inward, causing the chain to break, i.e. the teeth are damaged.

[0036] Preferably, the tooth base 130 is provided with a groove 133 on both sides in the first direction for installing the cloth belt.

[0037] It can be understood that in the present embodiment, the sub-teeth 100 on the sub-chain are connected together by a long strip cloth belt, which is the sub-tooth base belt. The tooth base 130 of the sub-teeth 100 is used to connect the sub-tooth base belt. The tooth base 130 is provided with a horizontal groove 133 in the middle of both sides in the first direction. The sub-tooth base belt can be installed in the groove 133 by strong glue, so that several sub-teeth 100 form a sub-chain. Of course, the sub-tooth base belt can also be installed in the groove 133 by other connection methods.

[0038] Preferably, the tooth base 130 is provided with a chamfer 134 on both sides in the second direction.

[0039] Specifically, when the sub-chain is bent inward, the sub-teeth 100 will be squeezed inward, and the tooth base 130 will also be squeezed in the second direction. Therefore, in order to prevent the tooth base 130 from being damaged due to squeezing, the tooth base 130 is provided with a chamfer 134 on both sides in the second direction. This can provide more space for the tooth base 130 to move closer to each other, which can reduce the damage to the tooth base 130 when the sub-chain is bent inward.

[0040] Preferably, the connecting part 140 is arranged on the symmetry axis of the tooth base 130 in the second direction, and the lengths of the first protrusion 150 and the second protrusion 160 in the second direction match the connecting part 140. The connecting part 140 is perpendicular to the upper surface of the tooth base 130, and the connecting part 140 is also perpendicular to the first protrusion 150 and the second protrusion 160.

[0041] In the embodiment, the connecting portion 140 is vertically arranged on the upper surface of the sub dental base 130, and the connecting portion 140 is located on the symmetry axis of the sub dental base 130 in the second direction, which is arranged to facilitate the cooperation of the sub chain with the female chain; in addition, the lengths of the first protruding portion 150 and the second protruding portion 160 in the second direction are the same as the length of the connecting portion 140, which can avoid the mutual influence of the adjacent two sub teeth 100.

[0042] Preferably, the two side edges of the first protruding portion 150 and the second protruding portion 160 in the second direction are provided with arc-shaped guide surfaces 170.

[0043] It can be understood that when the sub chain cooperates with the female chain, the sub teeth 100 will slide in the tooth cavity of the female chain, and by arranging the two side edges of the first protruding portion 150 and the second protruding portion 160 in the second direction as arc-shaped guide surfaces 170, the jamming during sliding of the sub chain can be reduced to make it smoother during relative sliding of the female chain.

[0044] Preferably, the two ends of the first protruding portion 150 and the second protruding portion 160 in the second direction are provided with extension portions 180, the extension portions 180 of the two adjacent sub teeth 100 abut each other, and the abutting surfaces 181 are smooth arc-shaped surfaces.

[0045] In addition, another embodiment is also provided, which is specifically provided with extension portions 180 at the two ends of the first protruding portion 150 and the second protruding portion 160 in the second direction on the basis of the above-mentioned embodiment, as shown in FIGS. 3 and 4; the two ends of the first protruding portion 150 and the second protruding portion 160 are each provided with an extension portion 180 which exceeds the length of the connecting portion 140, and the two adjacent extension portions 180 can abut each other; it should be noted that the abutting surfaces 181 are all smooth arc-shaped surfaces, so that when the sub chain is bent inward, the adjacent extension portions 180 abut each other, and since the abutting surfaces 181 are smooth arc-shaped surfaces, the abutting surfaces 181 will force the first tooth 110 and the second tooth 120 to tilt in opposite directions, which can also prevent the first tooth 110 and the second tooth 120 from being damaged due to mutual extrusion.

[0046] Preferably, the sub teeth 100 are injection-molded integral parts.

[0047] It can be understood that the sub teeth 100 in the present application are injection-molded integral parts, which not only improves the production efficiency of the sub teeth 100, but also enhances the overall structural strength.

[0048] Preferably, the proportion of the gap between the two adjacent sub teeth 100 relative to the length of the sub teeth 100 in the second direction is specifically between 1 / 5 and 1 / 3.

[0049] In addition, in the embodiment, when the sub-chain is bent outwardly when cooperating with the master chain, the gap between the two adjacent sub-element teeth 100 of the sub-chain is greatly increased, which is easy to cause the sub-element teeth 100 to be separated from the inner cavity of the master tooth of the master chain and cause the chain to break, therefore, in the embodiment, the gap between the two adjacent sub-element teeth 100 is reduced compared with the prior art, specifically, the ratio of the gap between the two adjacent sub-element teeth 100 to the length of the sub-element teeth 100 in the second direction is between 1 / 5 and 1 / 3, in this way, when the chain is bent outwardly, the distance between the sub-tooth bases 130 of the sub-element teeth 100 changes less, and thus the sub-element teeth 100 are less likely to be separated from the inner cavity of the master chain.

[0050] The application also discloses a breakage-proof sliding chain, which comprises a master chain and the breakage-proof sub-chain.

[0051] In addition, the application also discloses a garment, which comprises the breakage-proof sliding chain.

[0052] It should be noted that in the present specification, the relationship terms such as first and second are only used to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between the entities.

[0053] The various embodiments in the present specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be mutually referred to.

[0054] The above has carried on the detailed introduction to the embodiment provided by the application. The principle and implementation mode of the application are described by applying specific examples in this paper, and the above embodiment description is only used to help understand the method and core idea of the application. It should be pointed out that for ordinary skilled in the art, without departing from the principle of the application, the application can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the claims of the application.
