It is typically a ring structure and functions to transmit force, guide motion, or transport goods. It has wide applications in machinery, lifting, transportation, and many other fields. Special-shaped chains, in contrast to standard chains, are non-standard chains formed through special structural designs, material selection, or functional innovations. Their link shapes, connection methods, or overall form deviate from conventional practices to adapt to specific working conditions.

[0003] Both irregular and standard chains are mostly fixed with screws. However, if the chain length is inconsistent with the required length or is damaged and needs to be replaced, it needs to be disassembled with disassembly tools, which takes a long time and affects work efficiency. Therefore, there is a need to propose an irregular chain. Utility Model Content

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0023] like Figures 1 to 5 As shown, this utility model proposes an irregularly shaped chain, including an irregularly shaped chain body 1, which includes multiple irregularly shaped chain blocks 2. Each irregularly shaped chain block 2 includes a connecting tail block 201, and a connecting head block 202 is provided on the rear side of the connecting tail block 201. The connecting tail block 201 and the connecting head block 202 are fixedly connected. A connecting groove 203 is provided on the rear side of the connecting head block 202. The width of the connecting tail block 201 is the same as the width of the connecting groove 203. The connecting tail block 201 and the corresponding connecting groove 203 are slidably connected, facilitating the connection of two adjacent irregularly shaped chain blocks 2. For assembly, pin holes 204 are provided through the left and right sides of the connecting tail block 201, and pin holes 205 are provided through the left and right sides of the connecting head block 202. When assembly is required, the same connecting pin 6 can be installed inside the pin holes 204 and 205 for assembly. Fixing blocks 3 are provided on both the left and right sides of the connecting head block 202, and the left and right sides of the connecting head block 202 are fixedly connected to the fixing blocks 3. Connecting plates 4 are provided on the upper and lower sides of each fixing block 3, and the fixing blocks 3 are fixedly connected to the connecting plates 4. The connecting plates 4 have the ability to recover from bending deformation.

[0024] Triangular blocks 5 are provided on the opposite sides of the two connecting plates 4. The connecting plates 4 and the triangular blocks 5 are fixedly connected. The triangular blocks 5 are right-angled triangles, with the right-angled sides of the two triangular blocks 5 fixedly connected to the opposite sides of the two connecting plates 4. The inclined surfaces face outwards, allowing the two triangular blocks 5 to pass through the U-shaped limiting block 9. The same connecting pin 6 is slidably provided inside the corresponding pin holes 1 204 and 205. The connecting pin 6 can connect two adjacent irregular chain blocks 2. A pin head 7 is provided on the left end of the connecting pin 6. The left end of pin 6 is fixedly connected to the right side of pin head 7. Pin cap 8 is slidably provided on the right end of connecting pin 6. U-shaped limiting blocks 9 are provided on the front side of pin head 7 and pin cap 8. The front side of pin head 7 and pin cap 8 is fixedly connected to U-shaped limiting blocks 9. The two U-shaped limiting blocks 9 are mutually separated on the side that abuts against the corresponding triangular block 5. The triangular block 5 passes from one side of U-shaped limiting block 9 to the other side, and the right angle side can abut against U-shaped limiting block 9 so that pin head 7 and pin cap 8 can be stably installed on both sides of connecting head block 202 to ensure connection stability.

[0025] Each U-shaped limiting block 9 has two slots 10 on one side, and a groove 11 is formed between the two slots 10. A rubber strip 12 is installed inside the groove 11, and the rubber strip 12 is embedded in the groove 11. The rubber strip 12 has high friction, which allows it to be stably placed inside the groove 11. Each end of the rubber strip 12 has a baffle 13, and the rubber strip 12 and the baffle 13 are fixedly connected. Each baffle 13 is slidably connected to the corresponding slot 10. The position of the rubber strip 12 ensures that the baffle 13 is stably installed inside the slot 10. The two baffles 13 are attached to the opposite sides of the two corresponding connecting plates 4. The baffles 13 can limit the connecting plates 4 to prevent the connecting plates 4 from bending and causing the triangular block 5 to pass through the U-shaped limiting block 9. This ensures the stability of the connection between the connecting head block 202 and the pin head 7 and pin cap 8. The front side of the pin head 7 and pin cap 8 is provided with a set of ear plates 14. The pin head 7 and pin cap 8 are fixedly connected to the ear plates 14.

[0026] Each set of ear plates 14 is provided with a limit rod 15, which is fixedly installed between each set of ear plates 14. A spring 16 is sleeved around the outer ring of each limit rod 15, and each spring 16 has a pressing plate 17 at both ends. The spring 16 provides a constant force to the two pressing plates 17, keeping them at the ends of the limit rod 15. The pressing plates 17 are slidably connected to the limit rod 15, and the limit rod 15 guides and limits the pressing plates 17, ensuring they maintain a straight-line running state. The pressure plates 17 are located on the upper and lower sides of the two triangular blocks 5 respectively. Each pressure plate 17 has a hook plate 18 on one side. The pressure plates 17 and hook plates 18 are fixedly connected. When it is necessary to disassemble the connection between the pin head 7, the pin cap 8 and the connecting head block 202, the two hook plates 18 can be moved in a direction closer to each other, thereby driving the two pressure plates 17 to press the triangular blocks 5, thereby completing the connection of the two connecting plates 4, and then causing the triangular blocks 5 to detach from one side of the U-shaped limiting block 9 to the other side, so that the pin head 7 or the pin cap 8 can be disassembled from the left and right sides of the connecting head block 202.

[0027] In this embodiment, when using this device, firstly, when assembling multiple irregularly shaped chain blocks 2 into an irregularly shaped chain body 1, the connecting tail block 201 needs to be slid into the connecting groove 203 so that pin hole one 204 and pin hole two 205 are aligned. Holding the pin head 7, the right end of the connecting pin 6 is passed through pin hole one 204 and pin hole two 205. When the right side of the pin head 7 is in contact with the left side of the connecting head block 202, the two triangular blocks 5 will pass through the U-shaped limiting block 9 on the front side of the pin head 7, from the right side of the U-shaped limiting block 9 to the left side of the U-shaped limiting block 9, and the position of the pin head 7 is limited by the right side of the triangular blocks 5 being in contact with the left side of the U-shaped limiting block 9. Then, the baffle 13 passes through the inside of the slot 10 to limit the connecting plate 4, and the baffle 13 is limited by the rubber strip 12 installed inside the slot 11, so that the baffle 13 is stable on one side of the connecting plate 4. To prevent the connecting plate 4 from bending and ensure the stability of the connection between the pin head 7 and the connecting head block 202, the pin cap 8 is then slidably installed on the outer right end of the connecting pin 6. The two triangular blocks 5 on the right side are then passed through the right side of the U-shaped limiting block 9 from the left side, so that the pin cap 8 is stably connected to the right side of the connecting head block 202. The irregular chain body 1 can be assembled by following the above steps. When disassembly is required, the rubber strip 12 needs to be pried out from the inside of the slot 11, and the baffle 13 needs to be removed from the inside of the slot 10 to release the bending limitation on the connecting plate 4. Then, the two hook plates 18 are moved to the side that is closer to each other, which drives the two pressing plates 17 to move in the direction that is closer to each other, thereby giving the two triangular blocks 5 a force, causing the triangular blocks 5 to drive the connecting plate 4 to bend, thereby moving from one side of the U-shaped limiting block 9 to the other side, completing the disassembly.

[0028] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
