[0041] Please refer to Figure 1-Figure 6 , this embodiment provides an accessory link 100, the accessory link 100 includes a connecting plate 110, a supporting plate 120, a rubber plate 130 and two attachment plates 140;

[0042] The connecting plate 110 is bent to form a first connecting portion 111 and a second connecting portion 112. The first connecting portion 111 and the second connecting portion 112 are arranged at an angle.

[0043] The support plate 120 is connected to the first connection portion 111 , the rubber plate 130 is connected to the side of the support plate 120 away from the first connection portion 111 , and the second connection portion 112 is connected to the two attachment plates 140 ;

[0044] The two attachment plates 140 are both used to connect with the main chain body 220 .

[0045] Please refer to Figure 1-Figure 6 , and combined with Figure 7-Figure 9 , the working principle of the accessory link 100 is:

[0046] First, the accessory connection is applied to the accessory chain 200. During use, the accessory structure formed by the connecting plate 110, the supporting plate 120 and the rubber plate 130 can be used for lifting materials or carrying materials. Therefore, during use, the accessory structure, that is, the connecting plate 110, the supporting plate 120 and the rubber plate 130, will act as a load on the external material or structure.

[0047] Based on this, during the setting process of the accessory link 100, a structural setting method is adopted, which includes a connecting plate 110, a support plate 120, a rubber plate 130 and two attached plates 140, and its connecting plate 110 is bent to form a first connecting portion 111 and a second connecting portion 112, and the first connecting portion 111 and the second connecting portion 112 are set at an angle; wherein, the first connecting portion 111 and the second connecting portion 112 in this embodiment are vertically set, and in other embodiments of the utility model, the angles may be other angles.

[0048] The support plate 120 is connected to the first connection portion 111 , the rubber plate 130 is connected to the side of the support plate 120 away from the first connection portion 111 , and the second connection portion 112 is connected to the two attachment plates 140 ;

[0049] Therefore, after the attachment plate 140 is connected to the main chain body 220, it can contact with external materials through the rubber plate 130 under the driving action of the external power structure to carry or lift the materials. In the process of the rubber plate 130 contacting and carrying the external materials, a stable supporting effect can be formed by the arrangement of the support plate 120 and the connecting plate 110, which can improve its use strength and anti-deformation ability, that is, the rubber plate 130 can be stably supported by the bent connecting plate 110 and the support plate 120 to improve its load capacity and avoid damage such as breakage or deformation during use. Therefore, its service life can be extended, its maintenance frequency can be reduced, and its use and maintenance costs can be reduced.

[0050] In summary, the accessory link 100 is applied to the accessory chain 200, which can improve the use strength, reduce the deformation during use, improve its load-bearing capacity and use performance, thereby reducing the probability of structural fracture and rubber deformation and bending, thereby extending the service life, avoiding the impact on production efficiency, and reducing its maintenance cost. Based on this, in summary, please refer to Figure 1-Figure 9 The present embodiment also provides an accessory chain 200, which includes a connecting link 210, a main chain body 220, and at least one of the above-mentioned accessory links 100; the connecting link 210 is connected to the two free ends of the main chain body 220; the main chain body 220 includes a plurality of inner links 230 and a plurality of outer links 240 arranged in a staggered order; and the accessory link 100 is connected to the main chain body 220. It should be noted that the structure of the connecting link 210, the structure of the inner link 230 and the outer link 240 of the main chain body 220 can all adopt the existing technology.

[0051] Please refer to Figure 1-Figure 10In this embodiment, the inner link 230 is composed of an inner link plate 231, a sleeve 232 and a roller 233; the outer link 240 is composed of an outer link plate 241 and a pin 242; and the connecting link 210 is composed of a connecting outer link plate 211, a threaded connecting pin 212, a connecting link plate 213 and a locking nut 214; the specific connection method is the same as that in the prior art, so it will not be repeated here.

[0052] For further information, please refer to Figure 1-Figure 10 In this embodiment, when configuring the rubber plate 130 , in order to improve the supporting effect of the support plate 120 on the rubber plate 130 , the rubber plate 130 is bent, and the support plate 120 has a curvature that matches the rubber plate 130 .

[0053] Such a configuration can increase the contact area between the rubber plate 130 and the support plate 120 , thereby improving the supporting effect of the support plate 120 on the rubber plate 130 , thereby increasing the overall structural strength and anti-deformation capability.

[0054] For further information, please refer to Figure 1-Figure 10 In this embodiment, when configuring the above-mentioned connecting plate 110, a method of bending it to form a first connecting portion 111 and a second connecting portion 112 is adopted. Such a configuration is intended to facilitate the connection of the connecting plate 110 with the attachment plate 140 and the support plate 120;

The second connection members 116 are used to connect the second connection portion 112 and the attachment plate 140 .

[0058] The first connecting member 114 and the second connecting member 116 can both be rivet connecting members, that is, the second connecting portion 112 and the attachment plate 140 can be connected, and the first connecting portion 111, the support plate 120 and the rubber plate 130 can be connected by rivet connection; here, since the first connecting portion 111, the support plate 120 and the rubber plate 130 are connected by the same rivet, the structure can be simplified in this way, and the assembly cost can be reduced while the connection stability is improved.

[0059] In addition, based on the above structure, please refer to Figure 1-Figure 11 In order to improve the connection stability between the rubber plate 130 and the support plate 120, the accessory link 100 further includes a locking piece 150, which is connected to the first connecting member 114 and abuts against the side of the rubber plate 130 away from the support plate 120. That is, the first connecting portion 111, the support plate 120, the rubber plate 130 and the locking piece 150 can be fixed by rivets, so that the structure can be simplified in this way, and the assembly cost can be reduced while improving the connection stability.

[0060] In order to improve the connection stability, when configuring the attachment plate 140, the attachment plate 140 includes a plate body 141 and a third connection portion 142 arranged at an angle to the plate body 141, and the third connection portion 142 is used to connect with the second connection portion 112. The third connection portion 142 protrudes toward the outside of the plate body 141. It should be noted that the third connection portion 142 is arranged outward relative to the plate body 141, and the bending angle of the third connection portion 142 relative to the plate body 141 can be set according to the needs of use, for example, the third connection portion 142 can be made perpendicular to the plate body 141.

[0061] Furthermore, in order to facilitate the connection between the plate body 141 and the main chain body 220 , both ends of the plate body 141 along its extension direction are configured with third connection holes 143 , and the third connection holes 143 are used to connect with the main chain body 220 .

[0062] In summary, please refer to Figure 1-Figure 11 The accessory chain 200 using the accessory link 100 has good structural strength, which can reduce the deformation during use, improve its load-bearing capacity and performance, thereby reducing the probability of structural fracture and rubber deformation and bending, thereby extending its service life, avoiding the impact on production efficiency, and reducing its maintenance cost.
