Abstract
The utility model provides a cone-shaped nut expansion type expansion bolt. The structure of the cone-shaped nut expansion type expansion bolt is composed of a crimpling screw bolt, the cone-shaped nut, and an expansion tube, wherein, the expansion tube is sheathed outside the crimpling screw bolt; the cone-shaped nut is arranged on the crimpling screw bolt by screw threads and is arranged on the lower end of the expansion tube; the center of the crimpling screw bolt is provided with a central hole with the screw threads. The cone-shaped nut expansion type expansion bolt is characterized in reasonable design, simple structure, easy processing, small size, convenient operation, safety, anti-theft performance, etc.
Description
The utility model relates to a kind of metal fixing for building, specifically a kind of tapered nut expansion-fastening type expansion bolt.
EXPANSION ANCHOR BOLTS is widely used among the decorations construction of construction or indoor and outdoor, and among the installation of household electric appliance.Traditional expansion bolt is to be taper by screwing one, the nut of a threaded shank outer end makes taper that expansion tube is strutted and is fixed among the body of wall, and the in use existing deficiency of above-mentioned EXPANSION ANCHOR BOLTS is can leave long bolt head and influence the attractive in appearance of body of wall outside body of wall.
The purpose of this utility model provides a kind of body of wall tapered nut expansion-fastening type expansion bolt attractive in appearance that do not destroy.
The purpose of this utility model realizes in the following manner, the bolt of the band taper of prior art EXPANSION ANCHOR BOLTS is removed conical head, use general six square bolts as tightening bolt, nut is designed to tapered cup nut, expansion tube uses common expansion tube, tapered cup nut is placed an end of expansion tube, the other end of common six square bolts from expansion tube pierced into and be screwed on the tapered cup nut.The same during use with common EXPANSION ANCHOR BOLTS, an end of being with the expansion tube of tapered cup nut is injected in the fixed hole pre-drilled on the body of wall, screw common six square bolts from the other end of expansion tube, tapered cup nut is tightened in expansion tube, the end of expansion tube is strutted be fixed among the body of wall.Engineering construction for convenience is processed with screwed hole of centre at the center of common six square bolts and is used for as indoor furred ceiling, constructions such as the suspension of light fixture.
Accompanying drawing is the structural representation of tapered nut expansion-fastening type expansion bolt;
Explain below with reference to Figure of description tapered nut expansion-fastening type expansion bolt of the present utility model being done.
Tapered nut expansion-fastening type expansion bolt of the present utility model, its structure is to constitute by tightening bolt 3, tapered cup nut 4 and expansion tube 2, expansion tube 2 is enclosed within the outside that tightens bolt 3, tapered cup nut 4 is arranged on by screw thread and tightens the lower end that is positioned at expansion tube 2 on the bolt 3, and the center that tightens bolt 3 has threaded center hole 1.
Embodiment:
Tapered its processing and fabricating of nut expansion-fastening type expansion bolt of the present utility model is comparatively simple and convenient, processing and fabricating gets final product shown in the by specification accompanying drawing, processing technology is identical with the expansion spiral shell of prior art, use more simple and convenient, after having openning hole on the body of wall, together place the hole on the body of wall to locate together with the object that is fixed expansion bolt with percussion drill, screw bolt with wrench and get final product, on bolt, fix other objects as needs, on the bolt of available trumpet in the screwed hole of centre of bolt.
Tapered nut expansion-fastening type expansion bolt of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, little, the easy to use, safe characteristics such as antitheft of volume, thereby, have good value for applications.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
