Abstract

The invention relates to the field of fasteners, specifically a hexagon socket screw fastener, including a disassembly mechanism, a connection mechanism, a guide column, a lubrication mechanism, a protection mechanism, a waterproof mechanism, a pushing mechanism and an oiling mechanism; the interior of the lead screw A push mechanism is installed. When the fixing hole of the plate is too large to affect the stability of the fixation, pass the screw through the plate to realize the contact between the pressure plate and the plate. When the two connecting plates are opened, push the push rod towards the direction of the rubber bowl. The rubber bowl is lifted up to realize the lubricating oil inside the rubber bowl flowing out to lubricate the screw, which is convenient for installation. When the lubricating oil inside the rubber bowl flows out, it can flow from the oil inlet on the side wall of the screw to the inside of the oil storage chamber, and loosen it during disassembly The nut is separated from the plate by pressing the pressure plate, and the angle between the two connecting plates becomes smaller, the push rod moves towards the fixed block, the rubber bowl resets, and the pressure rod squeezes the oil received from the inside of the oil storage chamber. Out to the side wall of the screw for lubrication, easy to remove the nut.

Description

technical field

[0001] The invention relates to the field of fasteners, in particular to a hexagon socket screw fastener. Background technique

[0002] Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc., in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments All kinds of fasteners can be seen on the , chemical industry, instruments and supplies, etc., which are the most widely used mechanical basic parts.

[0003] However, when dismantling and lubricating the billboard socket head screws of the existing highways, the lubricating oil is directly poured on the surface of the screw and the nut with an oil gun, and the amount of oil cannot be precisely controlled to apply the lubricating oil to the surface of the ...
