Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a detachable metal chain, including a connecting pin 1. From the inside to the outside, inner chain plate 2 and outer chain plate 3 are sequentially arranged at both ends of the connecting pin 1. Connecting ports 4 are symmetrically opened on the surfaces of the inner chain plate 2 and outer chain plate 3, and the connecting ports 4 engage with the connecting pin 1. Rollers 5 are provided on the surface of the connecting pin 1. Threaded grooves are symmetrically opened at both ends of the connecting pin 1. Threaded blocks 6 are threadedly connected inside the threaded grooves. A fixing frame 7 is fixedly connected to the outside of the threaded blocks 6. The fixing frame 7 is symmetrically arranged on the outside. A fastening port 8 is provided. A locking groove 9 is provided on the outer side of the threaded block 6. An embedded pin 10 is engaged inside the locking groove 9. A U-shaped locking block 11 is fixedly connected to the outer side of the embedded pin 10. The cross-sectional area of ​​the locking block 11 is larger than the cross-sectional area of ​​the connection port 4. A locking cavity 12 is provided inside the embedded pin 10. A spring assembly 13 is fixedly connected inside the locking cavity 12. Fastening blocks 14 are fixedly connected to the top and bottom of the spring assembly 13. The fastening blocks 14 pass through the locking cavity 12 and are engaged with the fastening port 8.

[0023] refer to Figure 2 and Figure 5The surface of the fastening block 14 is provided with a reinforcing groove 15, and the inner wall of the fastening port 8 is provided with a reinforcing cavity 16. A reinforcing block 17 is slidably connected inside the reinforcing cavity 16, and the other end of the reinforcing block 17 passes through the reinforcing cavity 16 and is engaged with the reinforcing groove 15. A reinforcing column 18 is threadedly connected to the outside of the reinforcing cavity 16, and the other end of the reinforcing column 18 extends to the surface of the reinforcing block 17 and is rotatably connected to it.

[0024] As a technical optimization of this utility model, the arrangement of the reinforcing groove 15, the reinforcing cavity 16, the reinforcing block 17 and the reinforcing column 18 further enhances the stability of the connection between the fastening block 14 and the fastening port 8, prevents the fastening block 14 from loosening due to vibration or other reasons during the use of the chain, and improves the reliability of the overall chain structure.

[0025] refer to Figure 5 A reinforcing spring 19 is fitted on the surface of the reinforcing column 18, and the reinforcing spring 19 is located between the reinforcing cavity 16 and the reinforcing block 17.

[0026] As a technical optimization of this utility model, the reinforcement spring 19 plays a role in buffering and pre-tightening, which can compensate for the change in connection gap caused by factors such as wear or vibration to a certain extent, so that the reinforcement block 17 and the reinforcement groove 15 always maintain a tight fit, further improving the stability and reliability of the connection.

[0027] refer to Figure 2 and Figure 5 The surfaces of the two symmetrical fastening blocks 14 are fixedly connected with magnets 20, and the two magnets 20 are arranged in a repulsive manner.

[0028] As a technical optimization of this utility model, by setting the magnet 20, it can ensure that the fastening block 14 is more firmly engaged in the fastening port 8, and can also prevent the fastening block 14 from accidentally approaching or sticking to a certain extent, thus ensuring its normal operation.

[0029] refer to Figure 2 The surface of the connecting pin 1 is provided with a groove 21, and the inner wall of the roller 5 is provided with a protrusion 22, and the protrusion 22 fits into the groove 21.

[0030] As a technical optimization of this utility model, the setting of the groove 21 and the protrusion 22 enables the roller 5 to be more stably installed on the connecting pin 1, preventing the roller 5 from undergoing axial or radial displacement during rotation, thus ensuring the smoothness of the metal chain drive.

[0031] refer to Figure 1 The inner chain plate 2 has symmetrically formed snap ring grooves 23 on its surface, and the inner wall of the outer chain plate 3 is symmetrically fixedly connected with snap ring blocks 24, and the snap ring blocks 24 snap into the snap ring grooves 23.

[0032] As a technical optimization of this utility model, the setting of the snap ring groove 23 and the snap ring block 24 increases the tightness and stability of the connection between the inner chain plate 2 and the outer chain plate 3, so that when the metal chain is subjected to tension, the force can be distributed more evenly on each component, thereby improving the overall strength and service life of the metal chain.

[0033] The working principle and usage process of this utility model are as follows: When in use, the connecting pin 1 passes through the connecting port 4 on the inner chain plate 2 and the outer chain plate 3, connecting the inner chain plate 2 and the outer chain plate 3 together to form the basic structure of the metal chain. Rollers 5 are fitted onto the connecting pin 1 and can rotate flexibly on it. When the metal chain comes into contact with other components during transmission, the rollers 5 roll, reducing friction between the metal chain and other components, achieving efficient transmission. Simultaneously, the locking ring groove 23 on the inner chain plate 2 engages with the locking ring block 24 on the outer chain plate 3, increasing the tightness and stability of the connection between the inner chain plate 2 and the outer chain plate 3. This allows the force to be distributed more evenly across the components when the metal chain is under tension, improving the overall strength of the metal chain. When it is necessary to perform maintenance on the metal chain… During disassembly, first rotate the reinforcing column 18 to disengage the reinforcing block 17 from the reinforcing groove 15, then press down the locking block 11 to completely disengage it from the fastening port 8 and retract it into the locking cavity 12, and squeeze the spring assembly 13. Then, the embedded pin 10 can be pulled outward through the locking block 11. Next, the outer chain plate 3 and the inner chain plate 2 can be pulled out from the connecting pin 1 in sequence to complete the disassembly of the metal chain. Then, the metal chain can be installed in the reverse manner. In addition, if the connecting pin 1 and roller 5 of the metal chain are damaged, but the threaded block 6 and its connected parts are not damaged, the threaded block 6 can be rotated out of the threaded groove on the connecting pin 1 and reused. At the same time, the threaded block 6 can be replaced separately as a wear part, thereby reducing the later maintenance cost of the metal chain to a certain extent.
