[0029] The utility model aims to provide an explosion-proof sub-chain, which can prevent the sub-chain from exploding when the sliding chain is bent along the thickness direction of the cloth belt.

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

[0031] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0032] See also Figure 1 and Figure 2 The present embodiment provides an explosion-proof 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 divides the sub-tooth base 130 into a first sub-tooth base 131 and a second sub-tooth base 132, the first tooth 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, the second tooth 120 further comprising two protruding portions located above the second sub-tooth base 132 and connected to the end of the connecting portion 140.

[0033] Specific as Figure 1 and Figure 2 As shown, there are two types of sub-chain teeth 100, namely, first teeth 110 and second teeth 120. The sub-chain is composed of the first teeth 110 and the second teeth 120 staggered. The first teeth 110 and the 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 oppositely arranged with the connecting portion 140 as the central axis, that is, the first protrusion 150 and the second protrusion 160 are oppositely arranged in the first direction, as shown in FIG. Figure 1 As shown, the first protrusion 150 of the first tooth 110 protrudes away from the first direction. It should be noted that one side of the connecting portion 140 along the first direction is flush with the first protrusion 150, that is, the end of the connecting portion 140 is only protruded 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 arranged on the side of the connecting portion 140 facing the first direction. In this way, the first protrusion 150 and the second protrusion 160 are arranged on both sides of the connecting portion 140 with the connecting portion 140 as the central axis, and are staggered on both sides of the connecting portion 140; specifically, the first protrusion 150 is only located above the first sub-tooth base 131, and the second protrusion 160 is only located above the second sub-tooth base 132.

[0034] When the sub-chain composed of a plurality of sub-component teeth 100 is bent inward, that is, the first teeth 110 and the second teeth 120 of the sub-component teeth 100 are located inside the bend, and the sub-tooth base 130 is located outside the bend, as shown in FIG. Figure 2Bending method of the middle and upper 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, the first protrusion 150 on the first tooth 110 will be squeezed to the back side of the second protrusion 160 on the second tooth 120 when bending. Similarly, the second protrusion 160 on the second tooth 120 will be squeezed to the back side of the first protrusion 150 on the first tooth 110. In this way, the teeth 100 of the face component can be squeezed against each other when bending inward, causing the tooth chain to burst, that is, the damage of the teeth.

[0035] Preferably, grooves 133 for installing the cloth belt are provided on both sides of the tooth base 130 in the first direction.

[0036] It can be understood that in this embodiment, the sub-component teeth 100 on the sub-chain are connected together by a long strip of cloth, which is the sub-tooth base belt; the sub-tooth base 130 of the sub-component tooth 100 is used to connect the sub-tooth base belt, and the sub-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-component 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.

[0037] Preferably, both side surfaces of the tooth base 130 in the second direction are provided with chamfers 134 .

[0038] Specifically, when the sub-chain bends inward, the sub-component teeth 100 will be squeezed inwardly against each other, and the sub-tooth base 130 will also be squeezed against each other in the second direction. Therefore, in order to prevent the sub-tooth base 130 from being damaged due to squeezing as much as possible, chamfers 134 are provided on both side edges of the sub-tooth base 130 in the second direction. In this way, more space can be reserved for the sub-tooth base 130 to approach each other. This arrangement can reduce the damage to the sub-tooth base 130 when the sub-chain bends inward.

[0039] Preferably, the connecting portion 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 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 arranged on the upper surface of the sub-tooth base 130, and the connecting portion 140 is located on the symmetry axis of the sub-tooth base 130 in the second direction. This arrangement is to facilitate the use of the sub-chain with the mother chain; in addition, the lengths of the first protrusion 150 and the second protrusion 160 in the second direction in this embodiment are the same as those of the connecting portion 140, which can avoid mutual influence between two adjacent sub-component teeth 100.

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

[0042] It can be understood that when the sub-chain cooperates with the main chain, the sub-component teeth 100 will slide in the inner cavity of the teeth of the main chain. By setting the two side edges of the first protrusion 150 and the second protrusion 160 in the second direction as arc-shaped guide surfaces 170, the jamming of the sub-chain during sliding can be reduced so that it can slide more smoothly relative to the main chain.

[0043] Preferably, the first protruding portion 150 and the second protruding portion 160 are provided with extension portions 180 at both ends in the second direction, the extension portions 180 of two adjacent sub-component teeth 100 abut against each other, and the abutting surface 181 is a smooth arc surface.

[0044] In addition, another embodiment is provided herein. Specifically, based on the embodiment described above, an extension portion 180 is provided at both ends of the first protruding portion 150 and the second protruding portion 160 in the second direction. Figure 3 and Figure 4 As shown; both ends of the first protrusion 150 and the second protrusion 160 are provided with extension portions 180 that exceed the length of the connecting portion 140, and the two adjacent extension portions 180 can abut against each other; it should be noted that the abutting surfaces 181 are both smooth arc-shaped surfaces. In this way, when the sub-chain bends inward, when the adjacent extension portions 180 are squeezed against each other, 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. This arrangement can also prevent the first tooth 110 and the second tooth 120 from being squeezed against each other and causing damage to the teeth.

[0045] Preferably, the sub-component tooth 100 is an integrally-molded part.

[0046] It can be understood that the sub-component tooth 100 in the present application is integrally formed by injection molding, which not only improves the production efficiency of the sub-component tooth 100, but also enhances its overall structural strength.

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

[0048] In addition, in this embodiment, when the sub-chain is bent outward when cooperating with the main chain, the specific bending method is as follows: Figure 2 When the sub-chain is bent in the middle and lower part, the gap between two adjacent sub-component teeth 100 will increase significantly, which makes it easy for the sub-component teeth 100 to escape from the inner cavity of the mother tooth of the mother chain, causing the chain to break. Therefore, in this embodiment, compared with the prior art, the gap between two adjacent sub-component teeth 100 is reduced. Specifically, the ratio of the gap between two adjacent sub-component teeth 100 to the length of the sub-component teeth 100 along the second direction is between 1 / 5-1 / 3. In this way, when the sub-chain is bent outward, the distance between the sub-tooth bases 130 of the sub-component teeth 100 changes less, and thus the sub-component teeth 100 are less likely to escape from the inner cavity of the mother chain.

[0049] The present application also discloses an explosion-proof sliding chain, including a mother chain and the above-mentioned explosion-proof sub-chain. Therefore, the explosion-proof sliding chain with the explosion-proof sub-chain also has all the above-mentioned technical effects, which will not be described one by one here.

[0050] In addition, the present application also discloses a kind of clothing, including the explosion-proof sliding chain as described above. Therefore, the clothing with the explosion-proof sliding chain also has all the above-mentioned technical effects, which will not be described one by one here.

[0051] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0052] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0053] The above is a detailed introduction to the embodiments provided by the utility model. This article uses specific examples to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the method and core ideas of the utility model.
