Abstract

The utility model relates to a cover of a bolt, which comprises a hollow casing, wherein, the casing is sheathed on the outer edge of an elastic cover body, and the inner part of the cover body is provided with a containing part. The containing part which is provided with an opening covers on the bolt via the opening, and coats the bolt with the help of the elastic force of the cover body. Because the cover body in the casing of the utility model is elastic, when the containing part of the cover body covers the bolt and a nut, the shape of the cover body deforms corresponding to the shapes of the bolt and the nut with the help of the elastic force of the cover body, and the bolt and the nut are tightly coated by the cover body, which achieves the dual effects of avoiding bump by external force and avoiding the penetration of rain water.

Description

Bolt cover

Technical field

The utility model relates to a kind of clamp structure, relates in particular to a kind of external force of avoiding and touches and prevent the bolt cover that rainwater enters.

Background technique

General public building is as the bridge of street lamp, steel structure etc.; the capital combines with steel structure body with bolt; these are positioned at the bolt on the outdoor building thing; mostly shortage is protected and is directly exposed out; the part building can be painted with antirust at the bolt outside paint, but poor effect, and the bolt on these buildings exposes; passerby is if collision has injured danger accidentally, so necessity of being improved is arranged.

See also novel patent No. 87218100, it introduces a kind of protecting cover of bolt, and this protecting cover inner edge has a plurality of cards and ends bar in order to fasten on nut, makes the protecting cover cover cap on bolt, directly touches bolt or nut to prevent external force.

Yet the card of this protecting cover ends between bar and bolt and nut and has many slits, and after raining, rainwater easily resides in these slits, and makes rainwater be difficult for evaporation to scatter and disappear because of protecting cover covers, and it is stuck easily to cause bolt and nut to get rusty.

The model utility content

In order to overcome that existing bolt cover exists because the rainwater that the slit between bolt and nut is residual is difficult for evaporation, easily cause bolt and the nut stuck shortcoming of getting rusty, the utility model provides a kind of bolt cover, because the cover body in the shell has elasticity, the holding part cover cap that makes cover body is when bolt and nut, make cover body corresponding to the shape of bolt and nut and be out of shape by the elastic force of this cover body, and closely envelope bolt and nut, reach and avoid external force to touch and prevent the double effects that rainwater enters.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of bolt cover is characterized in that it has the shell of a hollow, and this shell is sheathed on rubber-like cover body outer rim, has a holding part in this cover body, and this holding part has an opening, on bolt, coats bolt by the elastic force of this cover body by this opening cover cap.

Aforesaid bolt cover, wherein to close on a section of this opening be one to coat section to the holding part of cover body, and this coatings section has a plurality of axially extended grooves, and this holding part has the lines of a plurality of ring-types.

Aforesaid bolt cover, wherein holding part is to be the big and inner less taper in adjacent openings place.

The beneficial effects of the utility model are, because the cover body in the shell has elasticity, the holding part cover cap that makes cover body is when bolt and nut, make cover body corresponding to the shape of bolt and nut and be out of shape by the elastic force of this cover body, and closely envelope bolt and nut, reach and avoid external force to touch and prevent the double effects that rainwater enters.

Embodiment

See also Fig. 1 to Fig. 4, the utility model is a kind of bolt cover, it has the shell 1 of a hollow, this shell 1 can be hard or soft material is made, this shell 1 is to be sheathed on a cover body 2 outer rims, and its profile is slick and sly moulding, these cover body 2 usefulness elastic materials are made, as: foam material, rubber, moulding material, and has a holding part 21 in this cover body 2, this holding part 21 has an opening 22, it is one to coat section 211 that the holding part 21 of this cover body 2 closes on a section of this opening 22, this coating section 211 has a plurality of axially extended grooves 212, the bore of this coating section 211 is slightly less than nut 31, has the lines 213 of a plurality of ring-types in this holding part 21, and this holding part 21 is to be the big and inner less taper in adjacent openings 22 places, supply by these opening 22 cover caps on bolt 31 and nut 32, and coat bolt 31 and nut 32 by the elastic force of this cover body 2.

Because this cover body 2 has elasticity, and have a plurality of axially extended grooves 212 again on this coating section 211, therefore, when entangling nut 32 with coating section 211, this coating section 211 is strutted the shape that is deformed into nut 32 complementations by nut 32, and by itself elastic force nut 32 is clamped, and prevents that rainwater from entering wherein, and the groove 212 that coats on the section 211 can be embedded on the arm of angle of nut 32 relatively, and has the strength that antagonism cover body 2 is rotated.Moreover, the lines 213 that has a plurality of ring-types in this holding part 21, can be embedded on the screw thread 311 of bolt 31, with the cover body 2 that creates antagonism by axially movable strength, cover body 2 can closely be combined with bolt 31 and nut 32, shell 1 then can be avoided external force direct collision bolt 31, can improve its Security.

In sum, the utility model is because the cover body 2 in the shell 1 has elasticity, holding part 21 cover caps that make cover body 2 are when bolt 31 and nut 32, cover body 2 is out of shape with the shape of nut 32 corresponding to bolt 31, and closely envelope bolt 31 and nut 32, reach and avoid external force to touch and prevent the double effects that rainwater enters.

Claims

1. a bolt cover is characterized in that it has the shell of a hollow, and this shell is sheathed on rubber-like cover body outer rim, has a holding part in this cover body, and this holding part has an opening, by this opening cover cap on bolt.

2, it is one to coat section that bolt cover according to claim 1, the holding part that it is characterized in that described cover body close on a section of this opening, and this coatings section has a plurality of axially extended grooves, and this holding part has the lines of a plurality of ring-types.

3, bolt cover according to claim 1 is characterized in that described holding part is to be the big and inner less taper in adjacent openings place.
