Abstract
The utility model relates to a suspended expansion rod, comprising a draw rod and an expansion sleeve. The utility model is characterized in that one end of the draw rod is flat cone, and the other end is provided with a ring; the draw rod is provided with the expansion sleeve; one end of the expansion sleeve is a cylinder, and the other end is an ellipsoid; longitudinal seam is arranged on the ellipsoid; two longitudinal seams are symmetrically arranged on the ellipsoid body; two connecting bars are arranged between the cylinder and the ellipsoid. Owing to the fact that the end of the draw rod of the utility model forms a flat cone, two longitudinal seams are symmetrically distributed on the ellipsoid on the expansion sleeve, and a combined suspended expansion rod is inserted into a hole during construction, the draw rod can be expanded tightly when rotated 90 DEG. Therefore, the utility model has the advantages of convenient construction and high efficiency.
Description
The utility model relates to a kind of mechanical fasteners technology, particularly a kind of supending roll type expansion rod.
When hanging article in finishing or engineering, the EXPANSION ANCHOR BOLTS of using all needs nut is screwed, and is during its construction cost, extremely inconvenient.
The purpose of this utility model provides a kind of supending roll type expansion rod, only needs pull bar to revolve during construction and turn 90 degrees and can swelling hang article.
Task of the present utility model is to realize like this, it comprises pull bar and expansion sleeve, it is characterized in that: an end of pull bar is the flat cone, the other end has a ring, and an expansion sleeve is arranged on the pull bar, and the one end is a cylinder, the other end is a cylindroid, have longitudinal joint on cylindrical body, symmetry has two longitudinal joints on ellipsoid, and two even muscle are arranged between two.
The utility model is owing to the end at pull bar is a flat cone, be symmetrically distributed with two longitudinal joints on the cylindroid of expansion sleeve, when construction, the supending roll type expansion rod of combination is inserted in the hole, only need rotating rod 90 degree to get final product swelling, therefore compared with prior art, has the high advantage of easy construction and efficient.
Fig. 1 is the plan view of the utility model supending roll type expansion rod.
Fig. 2 is the plan view of Fig. 1.
Drawing explanation: 1. pull bar 2. expansion sleeves
Now embodiment of the present utility model is described further in conjunction with above accompanying drawing.This supending roll type expansion rod comprises pull bar 1 and expansion sleeve 2, one end of pull bar 1 is an annulus, the other end is the flat cone, one expansion sleeve 2 is arranged on the pull bar 1, and its structure is that an end is a cylinder, and the other end is a cylindroid, opening a longitudinal joint on cylindrical body vertically separates it, symmetry has two longitudinal joints vertically on elliptical cylinder, with its dimidiation, is provided with two muscle between two cylindrical shells it is fused.Add man-hour, press earlier plate and die-cut sealing under the expansion shape of expansion sleeve, itself and pull bar are placed in the forming die are formed on the pull bar then.During construction, the supending roll type expansion rod is put into the acrosome hole, rotating rod annulus 90 degree, the flat cone of pull bar makes the expansion sleeve distending, at this moment, the supending roll type expansion rod securely by swelling in the hole of acrosome.
