Bolt-nut assembly with different colors

Abstract

The invention relates to the field of aircraft manufacturing and concretely discloses a bolt-nut assembly with different colors. The bolt-nut assembly comprises a bolt part and a nut part. The bolt part comprises a threaded rod, a first gasket and a first nylon plastic part. The first gasket and the first nylon plastic part are arranged on the threaded rod in a sleeving manner. The first nylon plastic part is embedded into the first gasket in a press-fit manner and in threaded connection with the threaded rod. The nut part comprises a second gasket, a nut and a second nylon plastic part. The second gasket is embedded into the second nylon plastic part in a press fit manner. One end of the nut is embedded into a central hole of a metal gasket. The bolt-nut assembly with different colors hasthe following advantages: specifications of bolts and nuts are distinguished by different colors so that assembly speed is high; and by additionally arranging nylon plastic parts, part surfaces are prevented from being scratched.

Description

technical field [0001] The invention relates to the field of aircraft manufacturing, in particular to a rainbow bolt and nut assembly. Background technique [0002] In the field of fasteners, the bolt-nut structure is the most common fastener, which has many advantages such as wide application and strong versatility, and is widely and massively used in many technical fields. Especially in the assembly and positioning of aircraft parts, many bolts and nuts need to be installed, and the existing technological bolts have the following disadvantages: [0003] 1. There are many types of bolts and nuts of various specifications during assembly. When bolts and nuts of similar specifications are mixed together, it is time-consuming and laborious to distinguish, and the efficiency is extremely low; [0004] 2. The process bolts are all pure metal parts. After the connection and positioning, the metal surface directly contacts the parts. It is determined that the paint layer on the s...
