Technical field
The utility model is related to chain, more particularly to a kind of escalator roller chain.
Background technology
With the increasingly raising of social life level, increasing business synthesis is risen in each large- and-medium size cities
Body, be usually mounted with many escalators in large-scale Commercial Complex, it is to avoid is needed because escalator quantity is very few
Wanting people to go on more distance can just find the defect of escalator, especially for those substantial amounts of distances of walking
The multiple escalators of people, as far as possible setting then seem and are even more important.
In recent years, often occur the report that people is gulped down on elevator in newspaper, news, socially gradually generate to elevator
Fear, some people even would rather stair climbing be also unwilling to take a lift, although some people take elevator, but have substantial amounts of Gu
Consider, thus it is guaranteed that the important leverage that lift safety operation is people lives and works in peace and contentment.
At present, Authorization Notice No. is terraced for the Chinese patent of CN205578615 discloses a kind of escalator in existing patent
Level chain, including a plurality of link units that mutual circulation is connected, each link units include central shaft, roller, are arranged in pairs in
The inner chain sheet of roller both sides and the outer chain sheet being arranged on the outside of inner chain sheet, do not rotate between outer chain sheet and central shaft, only logical
Cross the rotation that inner chain sheet realizes step chains, it is to avoid impaired problem of the outer chain sheet in rotation process.
But, the general only one of which active pin of chain of above-mentioned patent and the elevator for referring in the prior art, elsewhere
All it is that pin is dead, when the part-structure of above-mentioned chain is damaged, it is necessary to whole piece chain is changed, can wastes big in Renewal process
The human and material resources of amount.
