Rust-proof metal door plank fastener

Abstract

The invention discloses a rust-proof metal door plank fastener, and relates to the field of decoration. The fastener comprises screw heads, a screw rod and nuts, threads I are arranged on the periphery of the screw heads, the inner end of each screw head is fixedly connected with one end of the screw rod, the other end of the screw rod is matched with the screw port of each nut for use, and an outer hexagonal bulge is arranged on the outer end of each screw head; each screw head is externally connected with a cap body I through the corresponding thread I, a thread II is arranged on the periphery of each nut, and an outer hexagonal extension part is arranged on the outer end of each nut; the nuts are connected with a cap body II through the threads II, the inner rim of the cap body I is provided with grooves I, rubber rings I are arranged inside the grooves I, and the inner rim of the cap body II is provided with grooves II internally provided with rubber rings II. According to the rust-roof metal door plank fastener, tiny structures of bolts and the nuts are improved, decorative caps are arranged on the bolts and the nuts, and moreover, the rubber rings are installed on the bottoms of the decorative caps to insulate connecting parts of all screw ports, and the problem that normal bolts and nuts are easy to oxidize and erode is overcome.

Description

technical field [0001] The invention relates to the field of decoration, in particular to an antirust fastener for a metal door panel. Background technique [0002] With the development of the national economy and the progress of society, the requirements of the market are getting higher and higher. In order to adapt to the gradual transformation of modern architectural decoration to factory-like centralized production, and to meet the social requirements for environmental protection, recycling, material saving, and energy saving of materials, many public decoration spaces use metal veneer panels. Most of the traditional metal veneer building decoration structures adopt the construction technology of nailing directly on the steel skeleton. This process is relatively complicated, and the connection with the decorative parts needs to be fixed with bolts and nuts. These connections have the following disadvantages: Aware that the exposed bolts or nuts will affect the appearanc...

Problems solved by technology

Most of the traditional metal veneer building decoration structures adopt the construction technology of nailing directly on the steel skeleton. This process is relatively complicated, and the connection with the decorative parts needs to be fixed with bolts and nuts. These connections have the following disadvantages: Aware that the exposed bolts or nuts will affect the appearance and the decorative effect is not good; if the bolts and nuts are not used for fixing, the fastening effect will also be lacking.
