Description
Technical field
The utility model discloses a kind of protective equipment that matches with fastening piece and use, relate to more particularly effectively to prevent that fastening piece is corroded and by the protective equipment of corrosion.
Background technique
Fastening piece commonly used mainly includes screw; bolt and nut; and these fastening pieces in use be mostly be exposed to outdoor; it is not carried out special protection; particularly in the use of chemical field; the interior space of factory is often with corrosive liquid or gas; these have the parts that corrosive liquid or gas will expose equipment for a long time at leisure and corrode; especially to the corrosion failure maximum of fastening piece; when equipment need overhaul or keep in repair; some is corroded or the fastening piece of corrosion just is difficult to be removed; even can't pull down; commonly used bolt and nut in the fastening piece for example; if bolt and nut by heavy corrosion or corrosion after; because the screw thread on the bolt is destroyed; nut is by being corroded or corrosion; the nut that is screwed in like this on the bolt just almost can't turn; also just can't remove; have to carry out destructive dismounting; just can overhaul or maintenance operation; so not only can expend a large amount of artificial and man-hours; and the fastening piece of removing through destructiveness also can't re-use; thereby caused a large amount of wastes; in the needs emergency service; when big the and price of emergency maintenance or fastening piece quantity was more expensive, it is especially obvious that above-mentioned deficiency just seems.
The model utility content
The purpose of this utility model provides a kind of simple in structure in order to solve above-mentioned deficiency exactly, and cost of production is low, easy to use and fastening piece protective equipment that protection effect is good.
The technical solution that the utility model adopts in order to solve above-mentioned deficiency is as follows:
The fastening piece protective equipment, it mainly is made of main body, the inside of described main body offers the hole of matching with fastener bolt, and the outer upper end portion of described main body is provided with and is hemispherical or plane, the multiaspect shape that the sidepiece setting of main body is round shape or matches with spanner.
Described main body endoporus downside offers the cavity that matches with the fastening piece nut.
The lower ending opening place of described main body is provided with the soft shade that extends internally.
Be provided with the screw thread that matches with fastener bolt in the hole of described main body.
Be placed with rust preventive grease in the cavity of described main body and the hole.
The outer upper end portion of described main body offers " one " font or " * " flower shape.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: simple in structure, integral body is hollow structure, entire body adopts engineering plastics to make, cost of production is low, during use, directly the utility model is twisted to put on fastening piece by screw-driver or spanner and get final product, use very convenient, the lower ending opening place of main body is provided with soft shade on the one hand can well be with external corrosion gas and liquid and internal insulation, in the exposed parts of fastening piece all is wrapped in, protection effect is good, can play fastening effect on the other hand.
