    • PROBLEM TO BE SOLVED: To form a mushrooming expandable anchor as a socket for driving a device so as to facilitate an installing method regarding the expandable anchor as a self-fixing and fastening device to be installed in a support body for suspending a pipe wire or the other article to a ceiling. SOLUTION: The expandable anchor contains a freely crushable anchor part having an anchor strip to be expanded in the radial direction and the anchor part can not be pulled out from a bored hole inside the support body. A hole is bored by a drill inside the support body and the freely inflatable anchor is inserted to the bored hole. The anchor strip is provided on the bored hole so that the expandable anchor can not be pulled out of the bored hole by crushing the expandable anchor in cooperation with an internal thread of the expandable anchor and a thread on a screw that is screwed there. A threaded part of the base of the screw is suitable for mounting an article to be suspended. The base may be a revolving head part type. The drill may be located on an assembly of the expandable anchor. COPYRIGHT: (C)2004,JPO
    • 要解决的问题:形成一种可膨胀的可膨胀锚定件作为用于驱动装置的插座,以便于将可膨胀锚固件的安装方法作为安装在支撑体中的自固定和紧固装置,用于悬挂 管线或其他物品到天花板。 解决方案:可膨胀锚固件包含可自由压碎的锚固部件,其具有在径向方向上扩张的锚固带,并且锚固部件不能从支撑体内的钻孔中拉出。 钻孔在支撑体内部钻孔,并且可自由充气的锚固件插入到钻孔中。 锚定带设置在钻孔上,使得可膨胀锚固体不能通过与可膨胀锚固件的内螺纹和螺钉上的螺纹相配合地破碎可膨胀锚固件而从钻孔中拉出。 螺钉的基部的螺纹部分适于安装待悬挂的物品。 基座可以是旋转头部型。 钻头可以位于可膨胀锚固件的组件上。 版权所有(C)2004,JPO
