Abstract
The utility model discloses a protective cap of a bolt, comprising a hollow cap body of which one end is opened, wherein the cap body is coaxially provided with a cylindrical bolt cavity and a cylindrical nut cavity from inside to outside, the inner diameter of the bolt cavity is less than that of the nut cavity, and the bolt cavity is internally provided with a screw thread. By adopting the technical scheme, the opening of the cap body is buckled on the bolt and the nut, which are outwards exposed, the bolt is in screwed with the bolt cavity, the nut is arranged in the nut cavity, and the cap body just covers the bolt and the nut which is matched with the bolt, so that the bolt and the nut can not be sprinkled by the rain, polluted by the dust, and radiated by the sunshine, therefore, the bolt and the nut can not be corroded.
Description
Technical field
The utility model relates to a kind of bolt protective hat.
Background technique
At present, have a lot of outdoor equipments or communal facility to be provided with in the open, these equipment or facility use bolt to connect fixing mode usually; Bolt and matching used nut thereof often expose in the middle of air; Receive very easily corrosion behind rain wash and the contamination by dust, can on originally beautiful shell, stay a piece rust staining after the corrosion, influence the attractive in appearance of equipment; Even more serious is; Dismounting is extremely difficult after the corrosion, has to sometimes dismantle with destructive mode, and this puts to no little inconvenience for constructions such as dismounting and telephone-moving.
The model utility content
The utility model provides a kind of bolt protective hat that prevents exposed bolt corrosion in order to solve deficiency of the prior art.
For solving the problems of the technologies described above; The utility model adopts following technological scheme: the bolt protective hat comprises the cap body of a hollow and an end opening, coaxial from inside to outside columned bolt chamber and the nut cavity of being provided with in the cap body; The internal diameter of bolt chamber is provided with screw thread less than the internal diameter of nut cavity in the bolt chamber.
Said bolt chamber outer cap body be shaped as six prisms, nut cavity outer cap body be shaped as cylinder.
Said cap body is by the plastics integrated injection molding.
Adopt technique scheme; The opening of cap body is buckled to exposed screw bolt and nut; Bolt and bolt chamber are spirally connected, and nut is positioned at nut cavity, and the cap body is just in time with on bolt and the nut cap that is used thereof; Thereby avoided that screw bolt and nut is drenched with rain, contamination by dust and sunshine, screw bolt and nut just can not corrode like this; Bolt chamber outer cap body be shaped as six prisms, can use spanner to tighten six prisms like this cap body is tightened; The cap body is by the plastics integrated injection molding, and manufacturing process is simple, with low cost.
