摘要： A reassemblable reel which can easily be assembled and has a capacity as well as strength sufficient to contain and protect a great quantity of chips or other electronic components when in use and, after use, can easily be disassembled into compact parts which are easy to transport. The reassemblable reel generally includes two flanges and a reel hub having flexible plates formed therein. Each flexible plate is provided with tooth-shaped protrusions formed on the front and back ends of the flexible plate. The reel is so designed as to be formed by bringing the flanges into contact with both ends of the reel hub and pushing the flanges to engage the flexible plates with the tooth-shaped protrusions in stopper portions formed in the flanges. The tooth-shaped protrusions of each flexible plate can be disengaged by pushing the flexible plate from the outside of either flange in such a direction as to disengage the tooth-shaped protrusions. A disassemble device including key bars is selectively used to push the flexible plates in such a direction as to disengage their tooth-shaped protrusions. The key bars are removably inserted into through holes formed in the flanges. An abutment piece may also be provided with the disassembly device, positioned to correspond to the center cylinder of the reel hub.
摘要翻译：一种可重新组装的卷轴，其可以容易地组装并且具有足够的能力以及足够的强度以在使用中容纳和保护大量的切屑或其他电子部件，并且在使用后可以容易地拆卸成容易运输的紧凑部件。可重新组装的卷轴通常包括两个凸缘和其中形成有柔性板的卷轴毂。每个柔性板设置有形成在柔性板的前端和后端上的齿形突起。卷轴被设计成通过使凸缘与卷轴毂的两端接触而形成，并且推动凸缘将柔性板与形成在凸缘中的止动部分中的齿形突起接合。每个柔性板的齿形突起可以通过沿着任何一个凸缘的外侧将弹性板沿着使得齿形突起脱离的方向推动而脱离。选择性地使用包括键杆的分解装置以沿着使其齿形突起脱离的方向推动柔性板。键杆可移除地插入形成在凸缘中的通孔中。抵靠件还可以设置有拆卸装置，其被定位成对应于卷轴毂的中心圆筒。
