Embodiment approach

[0055] The implementation method is as follows: through the preparation process of the fastening screw 7 and the fastening seat 4, the strength, wear resistance and oxidation resistance of the surface coating are improved, and the brightness level and smoothness of the coating are improved through the potassium fluoride modified galvanized brightener. degree, improving overall durability.

[0056] Working principle: When in use, pre-embed the limit hoop 5 into the shell when stamping the shell, and embed the fastening seat 4 in the limit hoop 5, and rotate the connecting rod 603 around to drive the bottom pin around the hinged seat 604 rotates, and the hinged seat 604 rotates to drive the top connecting rod 603 to fit the embedded fastening seat 4. The fastening seat 4 can realize the deflection adaptation to the hinge 602 by fitting with the limit clamp rod, and the tight After the end of the fixing seat 4 is attached, after placing the punching position of the circuit board ...

Abstract

The invention discloses a fastener for household appliance manufacturing and a machining method thereof, and belongs to the technical field of household appliances. The fastener comprises a fastening seat and a fastening screw in threaded connection with the fastening seat; a sleeving ring is fixedly connected to the outer wall of the fastening seat, connecting mechanisms are rotatably connected to the periphery of the sleeving ring, and the tops of the connecting mechanisms are movably connected with adsorption type attaching mechanisms; and the tail end of the fastening screw is movably connected with a clamping mechanism, the clamping mechanism is fixedly connected to the top of the sleeving ring through a limiting hoop, and the connecting mechanisms comprise connecting blocks fixedly connected to one side of the sleeving ring. According to the fastener for household appliance manufacturing and the machining method thereof, through cooperation of the connecting mechanisms and the attaching mechanisms, the multi-axis adjusting capacity of the connecting mechanisms is matched with the attaching requirement of the attaching mechanisms, and the closed supporting effect on a fastening position is guaranteed through the flexible attaching mechanisms; and by means of the clamping mechanism and a limiting clamping hook at the top, fitting supporting of the fastening screw and a fastener body screwed in can be effectively improved, and the stability and the energy absorption effect of overall assembling and fixing are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of household electrical appliances, and in particular relates to a fastener for manufacturing household electrical appliances and a processing method thereof.
