Abstract
The utility model discloses an inverse hook type anti-drawing expanding screw bolt which is composed of a screw bolt, a screw cap and an expanding plug, wherein the screw bolt is hollow and the front end of the hollow inner part of the screw bolt is provided with a conical surface. A circular ring type inverse hook is arranged on the surface of an outer cylinder on the front end of the screw bolt, and an open groove is arranged in the front end of the screw bolt along the axial direction. The expanding plug is installed in the hollow inner part of the screw bolt and is a cylinder, and the front end of the expanding plug forms a spherical surface shape. The screw cap is provided with the screw threads of the screw bolt. The utility model has the advantages of favorable anti-drawing performance and convenient installation. After installed, the utility model is difficult to be drawn out even if a crowbar is adopted. When installed, the utility model is put into a drilled hole and the screw bolt can be fixed by using a hammer to strike the expanding plug through an iron rod.
Description
The utility model relates to a kind of EXPANSION ANCHOR BOLTS.
At present, EXPANSION ANCHOR BOLTS commonly used generally all is to lean on the conical surface of bolt front end that a hollow bloated tube that has opening slot is swollen in the prior art, thereby reach the fixing purpose that expands, the shortcoming of this EXPANSION ANCHOR BOLTS of the prior art is: because the nose circle conical surface of bolt is directly through less, after the tube that make to expand expands directly through also smaller, and the tube that expands generally all is ganoid cylinder, even thereby after bolt tightens, the frictional force of its bolt and mounting hole is also less, is easy to be pulled out; Secondly when mounted, bolt skids easily, installs very inconvenient.
The purpose of this utility model is: provide a kind of extraction-resistant behavior fluking type resistance to plucking EXPANSION ANCHOR BOLTS better, easy for installation.
The utility model is to constitute like this: it is made up of bolt (1), nut (2), the plug (3) that expands, bolt (1) is hollow, and the front end in bolt (1) hollow interior has conical surface (4), circular ring type barb (5) is arranged on the outer cylinder surface of bolt (1) front end, prolonging axial direction at the front end of bolt (1) opening slot (6) is being arranged, the plug (3) that expands is contained in bolt (1) hollow, and the plug (3) that expands is a spherical shape for cylindrical body and its front end, and nut (2) is gone up on the screw thread of bolt (1).
The utility model is compared with traditional expansion bolt, has good, the easy for installation advantage of extraction-resistant behavior, after it is installed, even adopt crowbar also to be not easy it is extracted.During installation, bore individual straight through the same hole earlier on the wall with bolt (1), bolt (1) is put into the hole, in the hollow hole with the higher iron rod inserting bolt (1) of intensity, and impact this iron rod with hammer, can swell by the front end of bloated plug (3) like this, its barb (5) is embedded in the wall brick bolt (1), thus bolt is fixing firmly on the wall.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the left view of accompanying drawing 1.
Embodiment of the present utility model: bolt (1) is made into surperficial screwed hollow cylinder, and produce conical surface (4) at the front end of its hollow interior, the tapering of conical surface (4) can not be too big, the plug (3) that guarantees to expand can form self-locking when being in contact with it, on the outer cylinder surface of bolt (1) front end, produce 1～5 circle circular ring type barb (5), and prolonging axial direction at the front end of bolt (1) and driving a criss-cross opening slot (6), the height that the degree of depth of opening slot (6) is about above the conical surface (4) gets final product, the plug (3) that will expand is made into the cylindrical body that front end is a spherical shape, and it is contained in bolt (1) hollow, nut (2) is gone up on the screw thread of bolt (1).
Claims (1)
1, a kind of fluking type resistance to plucking EXPANSION ANCHOR BOLTS, it is made up of bolt (1), nut (2), the plug (3) that expands, it is characterized in that: bolt (1) is for hollow, and the front end in bolt (1) hollow interior has conical surface (4), circular ring type barb (5) is arranged on the outer cylinder surface of bolt (1) front end, prolonging axial direction at the front end of bolt (1) opening slot (6) is being arranged, the plug (3) that expands is contained in bolt (1) hollow, the plug (3) that expands is that cylindrical body and its front end are spherical shape, and nut (2) is gone up on the screw thread of bolt (1).
