[0004] 1. When applying a traditional chain joint, when the chain needs to be repaired, the disassembly and installation at the chain joint are relatively cumbersome, making it time-consuming and laborious for maintenance personnel to operate;

[0005] 2. When applying most chain joints, since the chain joint is a manually connected structure at the back, it is at the weak part of the strength of the whole chain, and the existing chain joints lack a reinforcement effect, and the structural strength at the chain joint is relatively low. Content of the Utility Model

[0006] The purpose of the utility model is to provide a chain joint with an improved structure to solve the technical problems put forward in the background technique.

[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows: A chain joint with an improved structure includes a fixed rod. A card slot is opened on the surface of the fixed rod. A card block is inserted into the card slot. The other end of the card block is inserted into a sliding slot. The sliding slot is opened on the inner wall of a slot. A spring is fixedly connected to the bottom of the card block. The other end of the spring is fixedly connected to the inner wall of the sliding slot. A dial block is welded to the outside of the card block. The dial block is inserted into a strip-shaped hole. The strip-shaped hole is opened on the surface of a fixing plate.

[0008] Preferably, the slot is opened on the surface of the fixing plate. The fixed rod is inserted into the slot. Two connecting plates are fixedly connected to the top of the fixing plate.

[0009] Preferably, a sleeve is fixedly connected to the surface of an inner link plate. The inner link plate is attached to the surface of an outer link plate.

[0010] Preferably, a shaft rod penetrates through the outer link plate. The shaft rod passes through the inside of the sleeve.

[0027] To better understand the purpose, structure and function of the present invention, the following further describes in detail a chain joint with an improved structure of the present invention with reference to the drawings.

[0028] As Figures 1-4As shown in the figure, an improved structure of a chain joint of the present utility model includes a fixing rod 1. A clamping groove 7 is formed on the surface of the fixing rod 1. A clamping block 13 is inserted into the internal of the clamping groove 7, and the other end of the clamping block 13 is inserted into the internal of a sliding groove 12. Through the provided sliding groove 12 structure, it is convenient for the user to move the clamping block 13 structure. The sliding groove 12 is formed on the inner wall of a slot 14. A spring 16 is fixedly connected to the bottom of the clamping block 13, and the other end of the spring 16 is fixedly connected to the inner wall of the sliding groove 12. A dial block 11 is welded to the outside of the clamping block 13, and the dial block 11 is inserted into a strip-shaped hole 15. The strip-shaped hole 15 is formed on the surface of a fixing plate 8. In this way, when repairing the chain, when disassembling the chain joint, the dial block 11 can be toggled to make the clamping block 13 compress the spring 16 and enter the internal of the sliding groove 12, and no longer insert into the clamping groove 7. In this way, the chain joint structure can be disassembled. The disassembly and installation of the chain joint are relatively simple, saving time and effort for the maintenance personnel during operation.

[0029] The slot 14 is formed on the surface of the fixing plate 8. The fixing rod 1 is inserted into the internal of the slot 14. Two connecting plates 2 are fixedly connected to the top of the fixing plate 8. In this way, the fixing plate 8 is inserted on the fixing rod 1 by using the slot 14 to reinforce and fix the chain joint. And because the connecting plate 2 is fixedly connected above the fixing plate 8, the chain joint is further reinforced. In this way, the chain joint has a reinforcement effect, and the structural strength of the chain joint is relatively strong.

[0030] One end of the fixing rod 1 is fixedly connected to a joint plate 9. The fixing rod 1 passes through the internal of a sleeve 10. Through the provided joint plate 9 and sleeve 10 structures, it is convenient for the user to assemble the chain.

[0031] The sleeve 10 is fixedly connected to the surface of an inner link plate 3. The inner link plate 3 is attached to the surface of an outer link plate 5. Through the provided outer link plate 5 and inner link plate 3 structures, it is convenient for the user to use the chain.

[0032] A shaft rod 6 penetrates through the internal of the outer link plate 5, and the shaft rod 6 passes through the internal of the sleeve 10. Through the provided shaft rod 6 structure, the linkage between the outer link plate 5 and the inner link plate 3 of the chain is effectively increased, facilitating the user to use.

[0033] Rollers 4 are provided outside the sleeve 10. The shape of the rollers 4 is circular. Through the provided effect of the rollers 4, the linkage between the chain and the gear is effectively increased, facilitating the user to use.

[0034] Working principle of the chain joint with the improved structure: When using the chain joint with the improved structure, first, a slot 7 can be opened on the surface of the fixing rod 1, a clamping block 13 is inserted into the slot 7, and the other end of the clamping block 13 is inserted into the sliding groove 12. The sliding groove 12 is opened on the inner wall of the slot 14. Then, a spring 16 is fixedly connected to the bottom of the clamping block 13, and the other end of the spring 16 is fixedly connected to the inner wall of the sliding groove 12. A dial block 11 is welded outside the clamping block 13, and the dial block 11 is inserted into the strip-shaped hole 15. The strip-shaped hole 15 is opened on the surface of the fixing plate 8. In this way, when repairing the chain, when disassembling the chain joint, the dial block 11 can be toggled to make the clamping block 13 compress the spring 16 and enter the sliding groove 12, and no longer insert into the slot 7. In this way, the chain joint structure can be disassembled. The disassembly and installation of the chain joint are relatively simple, saving time and effort for maintenance personnel. Secondly, the slot 14 can be opened on the surface of the fixing plate 8, and the fixing rod 1 is inserted into the slot 14. Two connecting plates 2 are fixedly connected to the top of the fixing plate 8. In this way, the fixing plate 8 is inserted on the fixing rod 1 by using the slot 14 to reinforce and fix the chain joint. Also, because the connecting plate 2 is fixedly connected above the fixing plate 8, the chain joint is further reinforced. In this way, the chain joint has a reinforcement effect, and the structural strength of the chain joint is relatively strong.

[0035] It can be understood that the present invention is described through some embodiments. As is known to those skilled in the art, without departing from the spirit and scope of the present invention, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present invention.
