Description

Technical Field

[0001] The utility model relates to the technical field of hardware fasteners, and specifically relates to a hardware fastener convenient for installation. Background Art

[0002] Fasteners are a type of mechanical parts used for fastening connections and are extremely widely applied. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, molds, hydraulics, etc. On various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemical industry, meters, and supplies, various fasteners can be seen, and they are the most widely used mechanical basic parts. Its characteristics are that there are a wide variety of product specifications, different performance uses, and a very high degree of standardization, serialization, and generalization. Therefore, some people also call a type of fastener with existing national standards standard fasteners, or simply standard parts.

[0003] For example, a Chinese patent with the publication number CN220118487U discloses a hardware fastener convenient for installation, including a bolt. A slot is opened on the surface of the bolt, and a pin is arranged in the slot. A first limiting plate and a second limiting plate are respectively connected inside the bolt, a first elastic sheet is connected to the side surface of the first limiting plate, and a second elastic sheet is connected to the surface of the second limiting plate;

[0004] The technical solution recorded in this solution, through the settings of the pin, the first limiting plate, the first elastic sheet, the second limiting plate, and the second elastic sheet, when the nut is sleeved on the surface of the bolt, the first limiting plate and the second limiting plate will be pressed and retracted into the bolt, and at the same time, the two respectively apply pressure to the first elastic sheet and the second elastic sheet to make the two elastic sheets bend and deform. When the nut is tightened and no longer applies pressure to the first limiting plate and the second limiting plate, at this time, through the elastic recovery of the first elastic sheet and the second elastic sheet themselves, there is no need for additional steps to limit and prevent loosening of the bolt, and the operation is simple and the structure is simple with low cost.
