Abstract

Изобретение относитс  к машиностроению, в частности к средствам дл  анкерного креплени  оборудовани . Цель изобретени  - повышение надежности путем создани  предварительного распора втулки в начальный момент распора. Распорный дюбель содержит стержень 1 с резьбой 2 на одном конце и шейкой 3 на другом конце, переход щей в расшир ющийс  конический хвостовик 4. В шейке 3 размещена разрезна  втулка 7. Шейка стержн  имеет овальное поперечное сечение, при этом часть поверхности шейки расположена в прорези втулки, на поверхности которой выполнены выступы. После установки дюбел  в отверстие основани  эти выступы обеспечивают предотвращение движени  втулки. При некотором повороте стержн  овальное поперечное сечение его в зоне шейки обеспечивает начальный распор втулки. Окончательный распор производит конический хвостовик стержн . Повышение надежности достигаетс  за счет предотвращени  движени  втулки и ее предварительного распора. 2 ил.The invention relates to mechanical engineering, in particular to means for anchoring equipment. The purpose of the invention is to increase reliability by creating a pre-expansion sleeve at the initial moment of expansion. The expansion bolt shield has a rod 1 with a thread 2 at one end and a neck 3 at the other end, passing into an expanding tapered shank 4. In the neck 3 there is a spacing of sleeve 7. The neck of the rod has an oval cross section, and sleeve, on the surface of which the protrusions are made. After inserting the dowel into the hole of the base, these protrusions prevent movement of the sleeve. With a certain rotation of the rod, its oval cross-section in the area of the neck provides the initial thrust of the bushings. The final thrust produces a tapered shank rod. Increased reliability is achieved by preventing the sleeve from moving and pre-expanding it. 2 Il.
