傳統鏈條在設計上,主要是由鏈片、鏈滾、襯套,以及鏈軸等元件串接而成。而目前鏈條都是在工廠出廠時,就將鏈條的各個元件一一組裝結合完成,進而形成長度固定的鏈條後再販售。其中,在鏈軸與鏈片間的結合上,主要先使鏈軸的兩端穿過鏈片的穿孔,再利用機具鉚壓以將鏈軸兩端與鏈片固定住,也正因如此,以往的鏈片穿孔通常為一圓形貫孔之設計,但如此就無法讓消費者自行動手組裝鏈條,因為鏈軸與此種穿孔設計的鏈片,必須如上述方式利用機具才能結合。但有些消費者喜歡自行動手組裝,可增加樂趣與方便性,或者可依其需求組裝所需的鏈條,有鑑於此,本案藉由改變鏈片結構來提供一種可供自行組裝的鏈條相關設計。The traditional chain is mainly designed by connecting the elements such as the chain, the chain roller, the bushing, and the chain shaft. At present, when the chain is shipped from the factory, the components of the chain are assembled and assembled one by one, and then the chain of fixed length is formed and sold. Among them, in the combination of the chain shaft and the chain, the two ends of the chain shaft are mainly passed through the perforations of the chain, and then the machine is riveted to fix the both ends of the chain shaft and the chain piece, which is why In the past, the perforation of the chain was usually a circular through hole design, but it was impossible for the consumer to assemble the chain by hand, because the chain shaft and the chain of the perforation design must be combined by the implement as described above. However, some consumers prefer to assemble by hand, which can increase the fun and convenience, or can assemble the required chain according to their needs. In view of this, the case provides a self-assembled chain-related design by changing the structure of the chain.
因此,本新型之目的,即在提供一種結構創新,組裝容易之鏈條的串接單元。Therefore, the object of the present invention is to provide a tandem unit that is structurally innovative and easy to assemble.
