[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0022] like Figures 1 to 5 As shown, the present invention proposes a double-row chain structure, including chain 1 and chain 2. A T-shaped plate 3 is provided on the side of chain 1 near chain 2, and chain 1 and T-shaped plate 3 are fixedly connected. Two connecting plates 4 are provided on the bottom surface of T-shaped plate 3, and the bottom surface of T-shaped plate 3 is fixedly connected to the top surface of connecting plate 4. Each connecting plate 4 has elastic deformation capability. Triangular blocks 5 are provided on the bottom surface of both connecting plates 4, and the connecting plates 4 and triangular blocks 5 are fixedly connected. 5 is arranged in a right-angled triangle. Both ends of the top surface of the T-shaped plate 3 are rotatably equipped with a screw cap 6. The top surface of the screw cap 6 has a slot 18, which is convenient to insert a flathead screwdriver into the slot 18 to drive the screw cap 6 to rotate. The top surface of the screw cap 6 and the top surface of the T-shaped plate 3 are respectively provided with a set of limiting grooves. The same U-shaped block 19 is slidably installed inside each set of limiting grooves. The U-shaped block 19 is made of a material with strong friction to prevent it from falling out of the limiting groove and to ensure that the screw cap 6 will not rotate arbitrarily.

[0023] Each rotating cap 6 has an elliptical locking post 7 on its bottom surface. The bottom surface of the rotating cap 6 is fixedly connected to the top surface of the elliptical locking post 7. The elliptical locking post 7 is rotatably connected to the T-shaped plate 3. Each elliptical locking post 7 has a triangular locking groove 8 on both its left and right sides. A T-shaped plate 9 is provided on the side of the chain 2 near the chain 1. The chain 2 and the T-shaped plate 9 are fixedly connected. The top surface of each triangular locking block 5 fits against the bottom surface of the T-shaped plate 9, facilitating the limiting of the T-shaped plate 3 and the T-shaped plate 9, so that the T-shaped plate 3... The first type plate 3 and the second type plate 9 are stably connected. The top surface of the second type plate 9 is provided with a rectangular through groove 10. The two connecting plates 4 are respectively in a state of mutual contact with the inner walls of the left and right sides of the rectangular through groove 10, which facilitates the installation and disassembly of the connecting plates 4 and limits the position of the connecting plates 4. The bottom surface of the second type plate 9 is provided with two support plates 11. The bottom surface of the second type plate 9 is fixedly connected to the top surface of the support plate 11. A knob 12 is rotatably provided on the right side of the support plate 11 located on the right side.

[0024] A bidirectional screw 13 is located on the left side of the knob 12. The left side of the knob 12 is fixedly connected to the right end of the bidirectional screw 13. The left end of the bidirectional screw 13 extends through to the space between the two support plates 11. Both ends of the bidirectional screw 13 are threaded with pressing plates 14. Rotation of the bidirectional screw 13 can drive the two pressing plates 14 to move closer to each other. The two pressing plates 14 are located on the opposite sides of the two triangular blocks 5. By bringing the two pressing plates 14 closer together, the two triangular blocks 5 can be pressed inward, causing the connecting plate 4 to deform. The connecting plate 4 and the triangular locking block 5 are removed from the rectangular through slot 10 to facilitate the disassembly of the T-shaped plate 3 and the T-shaped plate 9. Each extrusion plate 14 has a trapezoidal block 20 on its top surface. The top surface of the extrusion plate 14 is fixedly connected to the bottom surface of the trapezoidal block 20. The bottom surface of the T-shaped plate 9 is provided with a trapezoidal groove at the position corresponding to each extrusion plate 14. The trapezoidal block 20 is slidably connected to the trapezoidal groove. The trapezoidal groove can guide and limit the trapezoidal block 20, thereby guiding and limiting the running trajectory of the extrusion plate 14, so that the extrusion plate 14 always maintains a straight running state.

[0025] A spring 15 is provided between the two extrusion plates 14. The spring 15 is fixedly installed between the two extrusion plates 14 and is sleeved on the outer ring of the double-acting screw 13. The double-acting screw 13 can be used to limit and guide the spring 15. Both ends of the top surface of the T-shaped plate 9 are provided with through holes 16. The elliptical locking post 7 is slidably connected to the through hole 16, which facilitates the passage of the elliptical locking post 7. A set of Z-shaped locking parts 17 is provided on the bottom surface of the T-shaped plate 9 at the position of each through hole 16. The T-shaped plate 9 and the Z-shaped locking parts 17 are connected. The Z-shaped clips 17 are fixedly connected, and each triangular slot 8 is engaged with a corresponding Z-shaped clip 17. By having the Z-shaped clip 17 engage with the interior of the triangular slot 8, the stability of the elliptical post 7 can be ensured, preventing the elliptical post 7 from coming out of the interior of the through hole 16, and ensuring the stability of the connection between the T-shaped plate 1 3 and the T-shaped plate 2 9. The Z-shaped clips 17 have elastic deformation capability, which facilitates the expansion of the two Z-shaped clips 17 to both sides when the elliptical post 7 is rotated, and facilitates the disassembly of the elliptical post 7 and the Z-shaped clips 17.

[0026] In this embodiment, when using this device, firstly, T-shaped plate 3 is fixedly connected to chain 1, and T-shaped plate 9 is fixedly connected to chain 2. Then, when installation is required, T-shaped plate 9 is placed directly below T-shaped plate 3, and then T-shaped plate 3 and T-shaped plate 9 are brought close together, so that the two triangular locking blocks 5 are installed on the bottom surface of T-shaped plate 9 through the rectangular through-slot 10, and the bottom ends of the two elliptical locking posts 7 are inserted into the bottom surface of T-shaped plate 9 through the through-hole 16, so that the Z-shaped locking piece 17 is engaged in the corresponding triangular locking slot 8. Then, the U-shaped block 19 is installed into the limiting slot, ensuring that the rotating cap 6 does not rotate arbitrarily, thus completing the connection of chain 1 and chain 2. When it is necessary to disassemble chain 1... When using chain 2, first remove the U-shaped block 19 from the inside of the limiting groove. Then, use a flathead screwdriver to insert into the inside of the slot 18 and rotate the screw cap 6 to rotate the rounded side of the elliptical locking post 7 to the front and rear sides, thereby expanding the two Z-shaped locking pieces 17. This facilitates the separation of the elliptical locking post 7 from the Z-shaped locking pieces 17. Then, rotate the knob 12. The rotation of the knob 12 drives the bidirectional screw 13 to rotate. The rotation of the bidirectional screw 13 drives the two pressing plates 14 to move closer to each other, thereby squeezing the two triangular locking blocks 5 inward. This causes the connecting plate 4 to deform, thereby allowing the connecting plate 4 and the triangular locking blocks 5 to come out through the rectangular through slot 10, thus achieving the disassembly of T-shaped plate 1 3 and T-shaped plate 2 9.

[0027] 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.
