    For holes (1) expanding conically inwards, expanding dowels can be used which have an expanding cone (3) positioned at the base of the hole, onto which an expanding sleeve (4) can be pushed. In this way, a positively locking connection is produced between the expanding dowel and the masonry (9). …<??>The expanding sleeve (4) is pushed on according to the application by the attachment part (5) projecting from the hole (1) being turned by means of a screw or the like, it being ensured that the expanding cone (3), which is connected to the attachment part (5) via a thread (10, 11), does not turn with the attachment part (5). …<IMAGE>…

    专利说明:

    The invention relates to mechanical engineering, in particular to fasteners fastened in drilled holes having conical expansion.
    The purpose of the invention is to facilitate the installation of dowels.
    FIG. 1 shows the expansion plug in working condition: FIG. 2 — Single-sided end of a spacer cone to prevent rotation; in fig. 3, also, an embodiment with several elements to prevent rotation.
    Expansion plug has pin 1 with thread 2 at one end and spacer cone 3 at the other end. A splined spreader sleeve 4 is mounted on a finger. A pin fastener 5 with an external thread 6 is screwed on a thread 2 of a finger 1 and has engagement elements 7 for a mounting tool at the free end. The engagement elements can be made in the form of flats or hex. At the end of the distance cone, at least one element 8 is made to prevent from turning. The element is made in the form of ribs, tapering outward. In an embodiment, several elements 9 can be made at the end of the spacer cone to prevent rotation. Elements 9 can be made in the form of cams or protrusions.
    On the side surface of the spacer cone 3 there is a protrusion 10 placed in the slot of the expanding sleeve.
    A sliding element 11 in the form of a plastic washer is installed between the fastener 5 and the expansion sleeve 4.
    The dowel is fixed as follows. . ,,. :
    The pin 1 is brought into engagement with the screw threading of the inner axial hole 12 of the fastener 5. As the fastener 5 rotates, it moves in the direction of the distance cone 3 and simultaneously moves the expansion sleeve until it takes up the position. Sliding element 11 reduces friction between fastener 5 and expanding sleeve 4. Elements 8 or 9 cut into the base
    holes 13, prevent rotation of the finger 1 relative to this hole. The protrusion prevents the expansion sleeve from being rotated relative to the finger 1. After securing the dowel in the drilled hole 13 of the base 14, fasten the object 15 and fix the nut 16 on the fastener 5.
    Preventing the dowel from turning in the hole during the fixing process makes it easier
    his installation) {s.
    The Invention 1. Spacing dowel for fastening in the holes conically widened inwards, comprising a threaded finger and an expansion cone for fastening a hole at the bottom, a splined crimping sleeve mounted on the finger and a rod fastener with an internal axial threaded hole screwed on
    the thread of the finger, which is made so that, in order to facilitate the installation of the dowel in the hole, the finger is made with at least one element to prevent the spreading cone on the end face and one protrusion on the lateral surface of the cone placed G slot of the expansion sleeve, and the dowel is equipped with a sliding element located between the fastener and the expansion sleeve.
    2. The dowel according to claim 1, of which is that the fastener at the free end is made with engagement elements for a mounting tool.
    3.Dyubel on PP. 1 and 2, that is, that the sliding element is made in
    form of plastic washer.
    4.Dubel on PP. 2 and 3, that is, that the engagement elements are made
    in the form of bald spots or hexagon.
