[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 screw. , causing the screw to not be lubricated evenly and wasting lubricating oil. If the hole on the surface of the plate wears and becomes larger, the accessories cannot fix the plate stably

Embodiment Construction
[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0027] Such as Figure 1-Figure 7 As shown, a hexagon socket screw fastener according to the present invention includes a disassembly mechanism 1, a connection mechanism 2, a guide column 3, a lubricating mechanism 4, a protection mechanism 5, a waterproof mechanism 6, a pushing mechanism 7 and an oiling mechanism 8; The bottom of the dismounting mechanism 1 for installing and disassembling the overall structure is welded with the connecting mechanism 2 for connecting objects, and the surface of the connecting mechanism 2 is threaded with the protective mechanism for fastening the workpiece 5. The bottom of the protective mechanism 5 is installed with the waterproof mechanism 6 used to prevent rainwater from entering the inside of the connecting m...

Abstract
The present invention relates to the field of fasteners, in particularly to an inner-hexagon screw fastener, comprising: a disassembling mechanism, a connecting mechanism, a guide post, a lubricatingmechanism, a protection mechanism, a water-proofing mechanism, a pushing mechanism and an oiling mechanism; the pushing mechanism is installed inside a screw rod; when a fixing hole of a plate is toolarge to affect the stability of fixing, the screw rod is used to pass through the plate to make a platen in contact with the plate; when two connecting plates are opened from each other, a push rod is pushed towards a rubber cup to jack up the rubber cup, thereby making lubricating oil flow out from the rubber cup so as to lubricate a screw rod and facilitate installation; when flowing out from the rubber cup, the lubricating oil can flow from an oil inlet in the sidewall of the screw rod and into an oil chamber; when disassembled, a nut is loosened to make the platen and the plate separate from each other, thus the angle between the two connecting plates becomes smaller; and the push rod moves towards a fixed block, the rubber cup restores, and a press rod extrudes oil from the oil chamber to the sidewall of the screw rod for lubrication, so it is convenient to unscrew 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 ...
