Description

A spring clip nut

technical field

The invention belongs to the technical field of aviation standard parts and relates to a spring clip nut.

Background technique

Standard parts are an important part of aviation products, and it is of great significance to shorten the product design and manufacturing cycle, reduce production costs, and improve product quality. Parts such as aircraft interior panels need to be disassembled frequently, and the fixed nuts are required to be easy to install and disassemble, and at the same time require excellent corrosion resistance and fatigue resistance.

The existing spring clip nuts have poor corrosion resistance and fatigue resistance, small twist-off torque and push-out force, and complex structures, which are not conducive to large-scale manufacture and use.

Contents of the invention

The purpose of the present invention is: the present invention uses existing stable materials to develop a spring clamp nut, which is very convenient for installation and disassembly, and at the same time enhances the corrosion resistance of the nut to meet the long life requirements of aircraft.

The technical scheme of the utility model is: a spring clip nut, characterized in that it consists of a nut body 1 and a spring clip 2, the nut body 1 is composed of a base 3 and a nut 4, the main body of the base 3 is a cuboid structure, two Side protruding lug structure, the nut 4 is located in the middle of the base 3, the nut hole runs through the base 3; A bottom plate hole 7 that matches the nut hole is provided, and a nut body mounting seat 8 is provided on the clamping plate 6 corresponding to the bottom plate hole 7. The nut body mounting seat 8 is flanged upwards on both sides and is provided with a flanging hole 9, which is connected with the nut body. 1. The lug structure of the base 3 cooperates to fix the nut body 1 on the splint 6, and a through hole is provided on the nut body mounting seat 8 to ensure that the nut hole penetrates the splint 6.

The bottom plate hole 7 is provided with a flange, which is used to cooperate with the mounting hole on the structure during installation to prevent the bottom plate 5 from moving.

The utility model has the advantages of convenient installation and disassembly, excellent corrosion resistance and anti-fatigue performance, and enhanced twisting torque and push-out force of the nut.

Detailed ways

A spring clip nut is characterized in that it is composed of a nut body 1 and a spring clip 2, the nut body 1 is composed of a base 3 and a nut 4, the main body of the base 3 is a cuboid structure, and the lug structure is protruded from both sides, the nut 4 is located in the middle of the base 3, and the nut hole runs through the base 3; the spring clamp 2 includes a bottom plate 5 and a splint 6, and a U-shaped clamping structure is formed between the bottom plate 5 and the splint 6, and the bottom plate 5 is provided with a bottom plate that matches the nut hole Hole 7, the position corresponding to hole 7 on the splint 6 is provided with a nut body mounting seat 8, the nut body mounting seat 8 is flanged upwards through both sides and the flanging hole 9 is set, and the lug structure of the base 3 of the nut body 1 Cooperate, thereby fix the nut body 1 on the splint 6, and the nut body mounting seat 8 is provided with a through hole at the same time, to ensure that the nut hole runs through the splint 6. The bottom plate hole 7 is provided with a flange, which is used to cooperate with the mounting hole on the structure during installation to prevent the bottom plate 5 from moving.

The utility model can be quickly fixed on the structure through spring clips, and has the advantages of convenient installation and disassembly, high wringing torque value and excellent corrosion resistance. The nut body can swim on the spring clip, and can be adjusted to align with the axis of the bolt when mated with the bolt. The front part of the spring clip is tilted up, which is convenient for inserting into the interlayer. The hole of the spring clip is raised, and can be embedded in the structural hole after installation to prevent the spring clip from moving. The nut body is made of a foreign mature high-temperature alloy steel (brand A286), the spring clip is made of spring steel (65Mn), and the surface treatment of the nut body is: passivation + molybdenum disulfide. The surface treatment of the spring clamp is cadmium-plated, and the diameter of the nut is Φ5mm. According to the model requirements, two kinds of clamping thickness specifications are developed.
