Abstract
The utility model relates to a bolt, in particular to a flat head expansion bolt, aiming to provide a dismountable expansion bolt with attractive appearance and repeatable using performance. The utility model comprises an expansion bolt body, an expansion pipe and a gasket, and is characterized in that: a fin (6) is arranged on the cone-shaped expansion nut (3), a fin slot (7) is installed on the expansion pipe (2), and a hexagonal bolt head (4) and a screw thread (5) are mounted on the expansion bolt body (1). The flat head expansion bolt of the utility model has rational design, simple structure and installation process and fast installation speed, and can be directly bored and installed in and after the installation of the equipment. Moreover, for the bolt head is not exposed, the utility model is provided with attractive appearance and anti-corrosion performance, and when the equipment is required to be dismounted, the operation is easy.
Description
Technical field
The utility model relates to a kind of bolt, especially a kind of tack EXPANSION ANCHOR BOLTS.。
Background technique
In our daily life, expansion screw is used very extensive at present, brings great convenience for people's work and life.But, the expansion screw that present people use always also has its deficiency, the EXPANSION ANCHOR BOLTS of prior art, general all by long bolt, the swelling cover of overcoat and nut constitute, though can finish above-mentioned said installing and fixing of task, but still have following defective in being to use: can not use during installation and the isodiametric bit bore of bolt, must earlier put equipment in advance and decide the hole, the equipment of removing then punches, and loads onto behind the bolt placement devices again, adding nut tightening fixes, could realize installing, the program complexity, installation rate is slow: EXPANSION ANCHOR BOLTS has long screw rod line head to be exposed after installing, look very not attractive in appearance, also very dangerous.After particularly fixation was removed, EXPANSION ANCHOR BOLTS was not easy to take out very much.People stay among the building often to removing the EXPANSION ANCHOR BOLTS of fixation.
Summary of the invention
The utility model provides a kind of novel EXPANSION ANCHOR BOLTS, is used to overcome the above-mentioned drawback of existing in prior technology.The purpose of this utility model provides and a kind ofly can take out reuse, dismountable expansion bolt attractive in appearance.
The utility model is to improve to realize on the basis of prior art EXPANSION ANCHOR BOLTS, it comprises EXPANSION ANCHOR BOLTS body, expansion tube and packing ring, it is characterized in that being provided with fin for the expanding nut of taper, expansion tube is provided with the fin groove, and the EXPANSION ANCHOR BOLTS body is provided with hex head bolt head and screw thread.
The utility model tack EXPANSION ANCHOR BOLTS is provided with 4 fins on expanding nut, expansion tube is provided with 4 fin grooves.
The utility model tack EXPANSION ANCHOR BOLTS is reasonable in design, and is simple in structure, and when being used for erection unit, after the placement devices, directly punching is installed, and installation procedure is simple, and speed is quick; Bolt head is not exposed, not only attractive in appearance but also be difficult for corrosion, need move when tearing equipment open, easily dismounting.
