Abstract
The utility model discloses a fastening screw structure, which comprises a nut part and a bolt part, wherein the bolt part comprises a screw and a screw cap, the nut part comprises a nut with internal threads and a nut cap fixed on one end of the nut, the nut cap has a conical protrusion in the middle, a conical cavity with internal threads of the nut is positioned closely to the nut cap, the front end of the screw is equipped with a column groove which is provided with four openings around, the nut is similar to the screw in length, the screw cap is equal to the nut cap in size and the groove is divided into four parts with the same size by the four openings thereof. The four openings are positioned around the column groove on the front end of the screw, therefore, when the bolt is screwed into the nut, the conical protrusion positioned in the nut part enters the column groove positioned in the bolt part, thus the four openings of the column groove are rolled out the bolt and the nut are locked.
Description
Technical field
The utility model belongs to the five metals field, particularly a kind of screw.
Background technique
Screw, also someone is its " screw " [Screw] (screw), " screw rod " (lead screw).Screw is common name in fact, and screw, lead screw are all distinguishing mutually.Screw generally is WOOD SCREWS; Be that front end is acuminous the sort of, pitch is larger, generally is used for fastening ligneous piece, working of plastics.Lead screw is machine screw (MACHINE SCREWS), is the sort of of front end tack, and pitch is less, evenly, generally is used for fastening metal, machine part.Rivet: in riveted joint, utilize self deformation or interference to connect by the part of riveting parts.The rivet kind is a lot, and informal.Commonly used have cup head, tack, semitubular rivet, solid rivet, sunk head rivet, self-plugging rivet, a tubular-shank rivet, and these normally utilize self deformation to connect by riveting parts.Be generally less than the cold riveting of using of 8 millimeters, greater than the rivet hot of using of this size.But exception is also arranged,, such as the nameplate on three ring locks, utilize the magnitude of interference riveted joint of rivet and lock body opening.
Summary of the invention
Main purpose of the present utility model is to provide a kind of screw structural of similar rivet.
For achieving the above object, the technical solution of the utility model is: screw structural comprises nut portion and bolt part; Bolt part is divided and is comprised screw rod and spiro rod cap, it is characterized in that described nut portion comprises female nut and the nut cap that is fixed on nut one end, there is a conical projections at the nut cap middle part, nut is female cone shape cavity near the part of nut cap, the front end of described screw rod has a cylinder shape groove, and described groove periphery has four openings.
As optimization, the threaded length of the length of described nut approaches.Described spiro rod cap is identical with described nut cap size.Four openings of described groove, be divided into four identical parts of size with groove.
The utility model fastening screw structure, be screwed in the process of nut at bolt, the nose circle cylindrical groove periphery of screw rod has four openings, the conical projections of nut portion setting enters bolt part and divides the cylindrical groove of setting, make four opening spreadings of garden cylindrical groove, thereby make screw bolt and nut locking.Spiro rod cap is identical with described nut cap size, can play the effect of rivet.
Description of drawings
Fig. 1 is the utility model fastening screw structure structural representation.
Embodiment
The utility model is described in further detail for embodiment's plan given below; but can not be interpreted as it is restriction to the utility model protection domain; those skilled in the art, to nonessential improvement and adjustment more of the present utility model, still belong to protection domain of the present utility model according to the utility model content.
The fastening screw structure, as shown in Figure 1, comprise nut portion and bolt part; Bolt part is divided and is comprised screw rod 1 and spiro rod cap 2, described nut portion comprises female nut 4 and is fixed on the nut cap 5 of nut 4 one ends, there is a conical projections 6 at nut cap 5 middle parts, nut 4 is female cone shape cavity near the part of nut cap 5, the front end of described screw rod 1 has a cylinder shape groove 3, described groove 3 peripheries have four openings, and groove 3 is divided into four identical parts of size.Threaded 1 length of the length of described nut 4 approaches.Described spiro rod cap 2 is identical with described nut cap 5 sizes.
This fastening screw structure, be screwed in the process of nut at bolt, the nose circle cylindrical groove periphery of screw rod has four openings, and the conical projections of nut portion setting enters bolt part and divides the cylindrical groove of setting, make four opening spreadings of garden cylindrical groove, thereby make screw bolt and nut locking.Spiro rod cap is identical with described nut cap size, can play the effect of rivet.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
