[0034] Please refer to Figure 1-Figure 5 This embodiment provides a conveyor chain 200 , which includes a plurality of chain links 210 and at least one hook 100 ; the plurality of chain links 210 are connected in sequence, and the hook 100 is connected to one of the chain links 210 .

[0035] The hook 100 is used to hang materials. Specifically, the hook 100 includes a connecting block 110, a hook body 120, and a stopper 130. The connecting block 110 is connected to the hook body 120, and the connecting block 110 is used to connect to a hanging member or a chain. The hook body 120 is bent to form a hanging portion 121. The stopper 130 is movably connected to the hook body 120 at an opening 122 of the hanging portion 121.

[0036] The stopper 130 is movably connected to the hook body 120 , and is provided with a limiting portion 131 . The limiting portion 131 is used to contact the inner side surface of the hanging portion 121 to limit the rotation of the stopper 130 toward the outer side of the hanging portion 121 .

[0037] Please refer to Figure 1-Figure 5 The working principle of the conveyor chain 200 is:

[0038] The conveyor chain 200 is used to transport materials, and the materials transported are hung on the hooks 100 on the conveyor chain 200. Taking the conveyor chain 200 as an example, it is used in a slaughterhouse. It is equipped with multiple hooks 100, and the hooks 100 are used to hang slaughtered livestock. During the use of the conveyor chain 200, the use of the hooks 100 can improve the stability of the hanging, thereby preventing the hung livestock from slipping during the conveying process.

[0039] Specifically, the hook 100 includes a connecting block 110 , a hook body 120 and a stopper 130 ;

[0040] The connecting block 110 is connected to the hook body 120, and its function is to connect to the chain. When connecting to the chain, it can be directly connected to the chain, or it can be indirectly connected to the chain by setting a hook as an intermediate connecting member.

[0041] The hook body 120 is bent to form a hanging portion 121, and the hanging portion 121 is not bent into a closed ring when bent, that is, an opening 122 is reserved. The purpose of the reserved opening 122 is to facilitate connection with a hanging member such as a hook or a ring for hanging materials; and the stopper 130 and the hook body 120 are movably connected to the opening 122 of the hanging portion 121. As a result, the stopper 130 can be moved relative to the hook body 120, so that the opening 122 of the hanging portion 121 can be relatively opened, so that the aforementioned hanging member such as a hook or a ring can be hung on the hanging portion 121; or, the stopper 130 and the hanging portion 121 form a ring to prevent the aforementioned hanging member such as a hook or a ring from slipping out of the opening 122;

[0042] In addition, please refer to the above content Figure 1-Figure 5 The stopper 130 is provided with a limiting portion 131, which is used to contact the inner side surface of the hanging portion 121 to limit the rotation of the stopper 130 toward the outer side of the hanging portion 121; since the limiting portion 131 adopts a method of contacting the inner side surface of the hanging portion 121, such an arrangement can increase the limiting effect on the stopper 130, and in this way, since the limiting portion 131 abuts against the inner side of the hanging portion 121, the rotation direction of the stopper 130 can be limited, so that the stopper 130 can only rotate in the direction inside the hanging portion 121, and is limited to rotating in the direction outside the hanging portion 121, thereby improving its stability in use;

[0043] In summary, the conveyor chain 200 can improve the stability during the process of hanging materials, and can also prevent the materials from falling off the hook 100 during the conveying process. Moreover, its structure is simple and can be easily replaced and maintained.

[0044] Further, please refer to Figure 1-Figure 5In this embodiment, when configuring the limiting portion 131, it can be seen from the above content that its function is to limit the rotation direction of the stop block 130 and to increase the abutment area with the hanging portion 121, thereby improving the stability in the abutment state. Based on this, the limiting portion 131 includes a first abutment surface 132 and a second abutment surface 133. The first abutment surface 132 is used to abut against the hook body 120 to limit the rotation of the stop block 130 toward the outside of the hanging portion 121; the second abutment surface 133 is used to abut against the hanging part sleeved on the hanging part 121 to limit the movement of the hanging part in the direction of separating from the hanging part 121. Moreover, the first supporting surface 132 is perpendicular to the second supporting surface 133. Such an arrangement enables a hook, a ring or other hanging part hung in the hanging portion 121 to be supported against the first supporting surface 132 when the hanging part is supported against the stop block 130. Since the first supporting surface 132 is perpendicular to the second supporting surface 133, the external force of the hook, the ring or other hanging part acting on the stop block 130 acts perpendicularly to the second supporting surface 133, and the stop block 130 can support the hook or the ring or other hanging part. Under this condition, the surface of the hanging portion 121 that is in contact with the first supporting surface 132 can be set flush. Compared with the curved arrangement in the prior art to prevent falling off, such an arrangement can facilitate the loading and unloading of hanging parts such as hooks or rings.

[0045] For further information, please refer to Figure 1-Figure 5 In this embodiment, to facilitate connection with a hook or chain, a positioning portion 111 is provided on the side of the connecting block 110 facing the hook body 120. Specifically, this embodiment employs a V-shaped groove 112 formed on the side of the connecting block 110 facing the hook body 120. This arrangement is intended to provide automatic centering through the V-shaped groove 112, thereby improving stability during hoisting and transportation.

[0046] In order to improve the stability of the connection, the hook 100 includes connecting bolts 113 , and the connecting block 110 is connected to the hook body 120 via two connecting bolts 113 ; wherein the two connecting bolts 113 are distributed on both sides of the positioning portion 111 .

[0047] When installing the stop block 130, the present embodiment adopts a method in which the stop block 130 is rotatably connected to the hook body 120. Based on this, the hook 100 also includes a connecting pin 141 and a limit pin 142. The stop block 130 is rotatably connected to the hook body 120 through the connecting pin 141. The limit pin 142 is passed through the connecting pin 141 and is used to limit the movement of the connecting pin 141 in the direction of separation from the hook body 120.

[0048] Furthermore, to enhance stability during hoisting and transport, the hook 100 also includes an elastic member disposed at the pivotal connection between the connecting pin 141 and the hook body 120, and configured to cause the stopper 130 to rotate toward a position of abutment against the hook body 120. This arrangement ensures that the stopper 130, under the action of the elastic member, maintains its retaining portion 131 in abutment with the hook portion 121. Furthermore, to enhance the strength of the hook 100, transitional curved surfaces are provided at the bends of the hook body 120.

[0049] In summary, please refer to Figure 1-Figure 5 By adopting the hook 100, the conveyor chain 200 can improve the stability, precision of fit, and flexibility of the hook 100 while ensuring strength and firmness, reduce stress concentration, increase load-bearing capacity, and enhance the service life and economic efficiency of the hook 100. This solves the problem in the prior art of conveyor chains 200 that the hooks 100 degrade in performance due to long-term use and are difficult to replace, as well as the problems of loud noise, easy falling of items, and poor stability during transportation under heavy load conditions.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
