Its weak point is: because the chain is often exposed to the air, the joints between the pin shaft and the inner chain plate, the pin shaft and the outer chain plate, and the inner chain plate and the outer chain plate are prone to rust, and it is easy to get stuck after rusting. Affects normal work and is difficult to disassemble

Embodiment Construction
[0025] like figure 1 As mentioned above, it is a kind of anti-rust chain, including a closed structure surrounded by several chain links 1, each chain link 1 includes two inner chain plates 101, two outer chain plates 102 and a chain pin 103, and the chain pins 103 are sequentially socketed There are outer link plate 102, inner link plate 101, inner link plate 101 and outer link plate 102. There is a gap between the two inner link plates 101 for sprocket tooth insertion, and the adjacent inner link plate 101 and outer link plate 102 Fitting, the outer link plate 102 and the inner link plate 101 are pressed together with an annular oily cotton 5. The annular oily cotton 5 not only ensures the relative rotation between the outer link plate 102 and the inner link plate 101, but also seals the outer link plate 102 and the inner link plate 101. The gap between the inner chain plates 101 is to avoid rusting. The inner wall of the connecting hole 104 of the outer chain plate 102 is c...

The invention relates to an antirust chain and a manufacturing method thereof. According to the device, a closed structure is defined by a plurality of chain links. Each chain link comprises two innerchain plates, two outer chain plates and a chain pin, wherein the chain pin is sequentially sleeved with one outer chain plate, one inner chain plate, the other inner chain plate and the other outerchain plate, a gap for inserting and connecting of chain wheel teeth is reserved between the two inner chain plates, the adjacent inner chain plates and outer chain plates are attached, end covers areconnected to the inner walls of connecting holes of the outer chain plates, and the end covers are used for sealing ends of the chain pin into the outer chain plates. Due to existence of the end covers, the end covers seal the corresponding chain pin ends into the connecting holes, and therefore the ends of the chain pins are prevented from being exposed in air and getting rust, and accordingly the situation that the chain pin ends and the outer chain plates rust, and later detachment is influenced is avoided.
Description
technical field [0001] The invention relates to the technical field of chains, in particular to an antirust chain and a manufacturing method thereof. Background technique [0002] The existing Chinese patent database discloses a patent named a self-lubricating chain structure, its patent application number is 200920309955.X, the application date is 2009.09.09, the authorization announcement number is CN201517585U, and the authorization announcement date is 2010.06.30 , the device includes an inner chain plate, an outer chain plate, a sleeve fixed at both ends on the inner chain plate, a roller set on the sleeve, a pin shaft riveted on the outer chain plate through the sleeve and the inner chain plate , The two ends of the pin are provided with concave holes. Its weak point is: because the chain is often exposed to the air, the joints between the pin shaft and the inner chain plate, the pin shaft and the outer chain plate, and the inner chain plate and the outer chain plate ...
