Description

Technical Field

[0001] This invention relates to the field of clothing accessories manufacturing technology, and in particular to an explosion-proof sub-chain, an explosion-proof slip chain, and clothing. Background Technology

[0002] Existing slip chains typically consist of a main chain and a secondary chain. The main chain has a toothed cavity, and the secondary chain has corresponding teeth that fit within that cavity. Relative movement between the main and secondary chains is achieved by the sliding of the secondary chain's teeth within the main chain's toothed cavity. Currently, they are widely used in clothing, packaging, pockets, tents, etc., where the teeth of the secondary chain typically slide within the toothed cavity of the main chain. However, in existing technology, when the secondary chain bends along the thickness of the fabric during transport, the teeth of the secondary chain will collide and be forced together, potentially causing the teeth to break or burst.

[0003] Therefore, how to prevent the sub-chain from bursting when the slip chain bends along the thickness direction of the fabric belt is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide an explosion-proof sub-chain that prevents the sub-chain from bursting when the slip chain bends along the thickness direction of the fabric tape. This invention also provides an explosion-proof slip chain including the aforementioned explosion-proof sub-chain, and clothing including the aforementioned explosion-proof slip chain.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An explosion-proof sub-chain includes: a plurality of spaced sub-tooths, each sub-tooth including staggered first teeth and second teeth, each first tooth and second tooth including a tooth base and a connecting portion disposed on the tooth base, the connecting portion dividing the tooth base into a first tooth base and a second tooth base, the first tooth further including a first protrusion located above the first tooth base and connected to the end of the connecting portion, and the second tooth further including a second protrusion located above the second tooth base and connected to the end of the connecting portion.

[0007] Preferably, the tooth base has grooves on both sides in the first direction for mounting the fabric tape.

[0008] Preferably, the tooth base has chamfers on both sides in the second direction.

[0009] Preferably, the connecting portion is disposed on the tooth base on the axis of symmetry in the second direction, and the lengths of the first protrusion and the second protrusion in the second direction match the lengths of the connecting portion.

[0010] The connecting part is perpendicular to the upper surface of the tooth base, and the connecting part is also perpendicular to the first protrusion and the second protrusion.

[0011] Preferably, the first protrusion and the second protrusion have arc-shaped guide surfaces on both sides in the second direction.

[0012] Preferably, the first protrusion and the second protrusion are provided with extensions at both ends in the second direction, and the extensions of the teeth of the two adjacent sub-pieces abut against each other, and the abutting surface is a smooth arc-shaped surface.

[0013] Preferably, the teeth of the sub-parts are injection molded integral parts.

[0014] Preferably, the ratio of the gap between two adjacent teeth of the sub-component to the length of the teeth of the sub-component along the second direction is specifically between 1 / 5 and 1 / 3.

[0015] An explosion-proof slip chain includes a main chain and an explosion-proof sub-chain, as described above.

[0016] A garment, including the aforementioned explosion-proof slip chain.

[0017] Compared with the above-mentioned background technology, the explosion-proof sub-chain provided by the present invention includes: a plurality of spaced sub-piece teeth, the sub-piece teeth including staggered first teeth and second teeth, each of the first teeth and second teeth including a sub-piece base and a connecting portion disposed on the sub-piece base, the connecting portion dividing the sub-piece base into a first sub-piece base and a second sub-piece base, the first tooth also including a first protrusion located above the first sub-piece base and connected to the end of the connecting portion, the second tooth also including two protrusions located above the second sub-piece base and connected to the end of the connecting portion.

[0018] Specifically, when a sub-chain composed of several sub-piece teeth bends inward, that is, when bending, the first and second teeth of the sub-piece teeth are located inside the bend, while the base of the sub-piece teeth is located outside the bend. At this time, the inner diameter of the bend will gradually decrease, and the first and second teeth will be squeezed inward. Since the first and second teeth are staggered, when bending, the first protrusion on the first tooth will be squeezed against the back of the second protrusion on the second tooth. Similarly, the second protrusion on the second tooth will be squeezed against the back of the first protrusion on the first tooth. In this way, the teeth of the sub-piece teeth can be squeezed against each other when bending inward, causing the teeth to burst, that is, the teeth to be damaged. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the description of this invention, it should be understood that the terms "upper", "lower", "end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0029] The purpose of this invention is to provide an explosion-proof sub-chain that can prevent the sub-chain from bursting when the slip chain bends along the thickness direction of the fabric tape.

[0030] It should be noted that in this embodiment, the X direction in the attached figure is defined as the first direction, and the Y direction is defined as the second direction. The first direction and the second direction are perpendicular to each other.

[0031] To achieve the above objectives, the present invention provides the following technical solution:

[0032] Please see Figure 1 and Figure 2 This embodiment provides an explosion-proof sub-chain, including: a plurality of spaced sub-tooths 100, each sub-tooth 100 including staggered first teeth 110 and second teeth 120, each first tooth 110 and second tooth 120 including a tooth base 130 and a connecting portion 140 disposed on the tooth base 130, the connecting portion 140 dividing the tooth base 130 into a first tooth base 131 and a second tooth base 132, the first tooth 110 also including a first protrusion 150 located above the first tooth base 131 and connected to the end of the connecting portion 140, the second tooth 120 also including two protrusions located above the second tooth base 132 and connected to the end of the connecting portion 140.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, the sub-chain has two types of teeth 100: a first tooth 110 and a second tooth 120. The sub-chain is composed of alternating first teeth 110 and second teeth 120. The first teeth 110 and second teeth 120 have the same overall shape, but the first protrusion 150 of the first tooth 110 and the second protrusion 160 of the second tooth 120 are arranged oppositely with the connecting part 140 as the central axis. That is, the first protrusion 150 and the second protrusion 160 are arranged oppositely in the first direction. Figure 1 As shown, the first protrusion 150 of the first tooth 110 protrudes away from the first direction. It should be noted that the connecting part 140 is flush with the first protrusion 150 on one side along the first direction. That is, the end of the connecting part 140 is only provided with a protrusion on one side. Similarly, the overall shape of the second tooth 120 is the same as that of the first tooth 110, except that the second protrusion 160 is provided on the side of the connecting part 140 facing the first direction. In this way, the first protrusion 150 and the second protrusion 160 are respectively staggered on both sides of the connecting part 140 with the connecting part 140 as the central axis. Specifically, the first protrusion 150 is only located above the first tooth base 131, and the second protrusion 160 is only located above the second tooth base 132.

[0034] When the sub-chain composed of several sub-piece teeth 100 bends inward, that is, when bending, the first tooth 110 and the second tooth 120 of the sub-piece teeth 100 are located inside the bend, while the tooth base 130 is located outside the bend, specifically as follows: Figure 2The bending method in the upper middle part; 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, when bending, the first protrusion 150 on the first tooth 110 will be squeezed against the back of the second protrusion 160 on the second tooth 120. Similarly, the second protrusion 160 on the second tooth 120 will be squeezed against the back of the first protrusion 150 on the first tooth 110. In this way, when the tooth 100 of the surface part is bent inward, the teeth will squeeze each other and cause the teeth to burst, that is, the teeth will be damaged.

[0035] Preferably, the tooth base 130 has grooves 133 on both sides in the first direction for mounting the cloth tape.

[0036] Understandably, in this embodiment, the teeth 100 of the sub-chain are connected together by a long strip of cloth, which is the tooth base strip; the tooth base 130 of the tooth 100 is used to connect the tooth base strip. The tooth base 130 has horizontal grooves 133 in the middle of both sides in the first direction. The tooth base strip can be installed in the grooves 133 by strong adhesive, so that several teeth 100 form a sub-chain. Of course, the tooth base strip can also be installed in the grooves 133 by other connection methods.

[0037] Preferably, the tooth base 130 has chamfers 134 on both sides in the second direction.

[0038] Specifically, when the sub-chain bends inward, the teeth 100 of the sub-component will squeeze each other inward, and the tooth bases 130 will also squeeze each other in the second direction. Therefore, in order to prevent damage to the tooth bases 130 due to squeezing, chamfers 134 are provided on both sides of the tooth bases 130 in the second direction. This allows for more space for the tooth bases 130 to approach each other, which can reduce the damage to the tooth bases 130 when the sub-chain bends inward.

[0039] Preferably, the connecting portion 140 is disposed on the tooth base 130 on the axis of symmetry in the second direction, and the lengths of the first protrusion 150 and the second protrusion 160 in the second direction match the lengths of the connecting portion 140; the connecting portion 140 is perpendicular to the upper surface of the tooth base 130, and the connecting portion 140 is also perpendicular to the first protrusion 150 and the second protrusion 160.

[0040] In this embodiment, the connecting portion 140 is vertically disposed on the upper surface of the tooth base 130, and the connecting portion 140 is located on the axis of symmetry of the tooth base 130 in the second direction. This arrangement is to facilitate the use of the sub-chain and the mother chain. In addition, in this embodiment, the lengths of the first protrusion 150 and the second protrusion 160 in the second direction are the same as those of the connecting portion 140, which can avoid mutual interference between adjacent teeth 100.

[0041] Preferably, the first protrusion 150 and the second protrusion 160 are provided with arc-shaped guide surfaces 170 on both sides in the second direction.

[0042] Understandably, when the sub-chain and the mother chain are engaged, the teeth 100 of the sub-chain will slide within the inner cavity of the teeth of the mother chain. By setting the two sides of the first protrusion 150 and the second protrusion 160 in the second direction as arc-shaped guide surfaces 170, the jamming when the sub-chain slides can be reduced so that it slides more smoothly relative to the mother chain.

[0043] Preferably, the first protrusion 150 and the second protrusion 160 are provided with extensions 180 at both ends in the second direction, the extensions 180 of the two adjacent sub-piece teeth 100 abut against each other, and the abutment surface 181 is a smooth arc surface.

[0044] Furthermore, this document also provides another embodiment, specifically, based on the embodiment described above, an extension portion 180 is provided at both ends of the first protrusion 150 and the second protrusion 160 in the second direction, as detailed below. Figure 3 and Figure 4 As shown; both ends of the first protrusion 150 and the second protrusion 160 are provided with extensions 180 that exceed the length of the connecting portion 140, and adjacent extensions 180 can abut against each other; it should be noted that the abutting surfaces 181 are all smooth arc surfaces. In this way, when the sub-chain bends inward, when adjacent extensions 180 are squeezed against each other, the abutting surfaces 181 will force the first tooth 110 and the second tooth 120 to tilt in opposite directions because the abutting surfaces 181 are smooth arc surfaces. This arrangement can also prevent the first tooth 110 and the second tooth 120 from squeezing against each other and causing damage to the teeth.

[0045] Preferably, the tooth 100 is an injection-molded integral part.

[0046] Understandably, the sub-part tooth 100 in this application is integrally molded by injection molding, which not only improves the production efficiency of the sub-part tooth 100, but also enhances its overall structural strength.

[0047] Preferably, the ratio of the gap between two adjacent sub-piece teeth 100 to the length of the sub-piece teeth 100 along the second direction is specifically between 1 / 5 and 1 / 3.

[0048] Furthermore, in this embodiment, when the sub-chain bends outward in conjunction with the parent chain, the specific bending method is as follows: Figure 2 The bending at the lower middle section will significantly increase the gap between two adjacent teeth 100 of the sub-chain. This makes it easy for the teeth 100 of the sub-chain to detach from the inner cavity of the mother chain, resulting in a chain breakage. Therefore, in this embodiment, the gap between two adjacent teeth 100 of the sub-chain is reduced compared to the prior art. Specifically, the ratio of the gap between two adjacent teeth 100 of the sub-chain to the length of the teeth 100 along the second direction is between 1 / 5 and 1 / 3. In this way, when the sub-chain bends outward, the distance between the tooth bases 130 of the sub-chain teeth 100 changes less, and the teeth 100 of the sub-chain are less likely to detach from the inner cavity of the mother chain.

[0049] This application also discloses an explosion-proof slip chain, including a main chain and the explosion-proof sub-chain described above. Therefore, the explosion-proof slip chain with this explosion-proof sub-chain also has all the above-mentioned technical effects, which will not be elaborated further here.

[0050] Furthermore, this application also discloses a garment including the aforementioned explosion-proof slip chain. Therefore, garments incorporating this explosion-proof slip chain also possess all the aforementioned technical effects, which will not be elaborated upon further here.
