Abstract
The utility model discloses a bolt connecting pair with a protecting jacket. The bolt connecting pair with the protecting jacket comprises a bolt and a nut. The nut is of the shape of a circular truncated cone. An antirust protection layer is arranged on the surface of the head of the bolt. An elastic washer is sheathed on the screw rod of the bolt. A cylindrical protecting jacket is arranged at the tail of the bolt. The protecting jacket is of a hollow structure. The internal surface of the protecting jacket is in close contact with the bolt, the nut and the elastic washer. The open end of the protecting jacket is hermetically connected with the elastic washer. The bolt connecting pair with the protecting jacket has the advantages of novel design, high strength and good antirust performance, and is suitable for popularization and application.
Description
Technical field
The utility model relates to a kind of bolt auxiliary connection, particularly a kind of bolt auxiliary connection with protecting jacket.
Background technique
The bolt auxiliary connection is one of most widely used fastening connection piece on the engineering, mainly comprise screw bolt and nut, because the screw bolt and nut long term exposure is moist and be full of in the rugged environment such as impurity particle, the corrosion aging speed of himself is very fast, and, bolt is being subjected to the external object bump can cause the damage of screw thread, thereby can cause bolt to connect getting loose and lost efficacy.
Summary of the invention
The purpose of this utility model just is to provide a kind of modern design, intensity height, the bolt auxiliary connection of the band protecting jacket of good antirust property.
To achieve these goals; the technical solution adopted in the utility model is such: the bolt auxiliary connection of band protecting jacket of the present utility model; comprise screw bolt and nut; described nut is frustoconic shape, and described bolt head surface is provided with the corrosion protection layer, is socketed with elastic washer on the screw rod of bolt; bolt tail is provided with the protecting jacket of tubular; protecting jacket is hollow structure, and its internal surface closely contacts with bolt, nut, elastic washer, and protecting jacket opening end and elastic washer are tightly connected.
As preferably, the corrosion protection layer is arranged on the inwall of described nut.
As preferably, described corrosion protection layer is spelter coating or zinc-chromium coating.
Compared with prior art; advantage of the present utility model is: the utility model modern design; the bolt head surface is provided with the corrosion protection layer; make bolt have higher antirust ability; protecting jacket can be included in bolt tail and nut, elastic washer in the protecting jacket; thereby realize the circle face protection to bolt integral body, make bolt not be subjected to extraneous bump and destroy, and prevent that corrosion liquid from invading the attachment portion of connected piece.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1; the bolt auxiliary connection of band protecting jacket of the present utility model; comprise bolt 1 and nut 2; described nut 2 is frustoconic shape; described bolt 1 head surface is provided with corrosion protection layer 3; be socketed with elastic washer 5 on the screw rod of bolt 1; bolt 1 afterbody is provided with the protecting jacket 4 of tubular; protecting jacket 4 is hollow structure; its internal surface closely contacts with bolt 1, nut 2, elastic washer 5; protecting jacket 4 opening ends and elastic washer 5 are tightly connected, and corrosion protection layer 3 is arranged on the inwall of described nut 2, and described corrosion protection layer 3 is spelter coating or zinc-chromium coating.
During use; earlier bolt 1 is passed the screw of workpiece 6; again elastic washer 5 is socketed on the bolt 1; spiro cap is connected on the bolt 1 then; at last protecting jacket 4 is socketed in bolt 1 afterbody; bolt 1 head surface is provided with corrosion protection layer 3; make bolt 1 have higher antirust ability; protecting jacket 4 selects for use plastic processing to form; can be subjected to thermal shrinkage, also can under certain pressure, shrink and be close to bolt 1; the outer surface of packing ring and nut 2, thus realize the circle face of bolt 1 integral body is protected; make bolt 1 not be subjected to extraneous bump and destroy, and prevent that corrosion liquid from invading the attachment portion of connected piece.
