Abstract

The utility model relates to an anti-slip rivet nut, which comprises a cylindrical rivet body and a brim arranged at one end of the rivet body, wherein a first inner bore and a second inner bore, which are coaxial, are arranged on the rivet body from the brim to the other end; the diameter of the second inner bore is smaller than that of the first inner bore; and moreover, the second inner bore is internally provided with a thread, and multiple protruding anti-slip bodies are arranged on the inner end face of the brim. According to the utility model, the multiple protruding anti-slip bodies are arranged on the inner end face of the brim, and the anti-slip bodies are tightly pressed into a riveting target during riveting, as a result, the combination effect of the rivet nut and the riveting target is enhanced and the rotating torque is greatly improved.

Description

Anti-skidding Insert Nut

Technical field

The utility model relates to a kind of Insert Nut, specifically a kind of anti-skidding Insert Nut.

Background technique

At present, Insert Nut has been widely used in the riveted joint of metal and nonmetallic plane or non-planar junction member.Compare with general rivet, wherein another structure can be for convenience detach after the Insert Nut riveted joint, combines the function of rivet and nut, is convenient to maintenance and renewal, so machinery manufacturing industry, shipbuilding industry, car industry and aviation field etc. have all begun to utilize.

The design proposal of Insert Nut is: section is shaped with screw thread in the lower hole of riveting body, after the staking, is fixed in the above with another structure of key screw of same size.Owing to match with screw, so whole tension and shearing resistance are all more intense.Certainly Insert Nut also has deficiency, if or smooth surface bigger than normal by the hole of riveting structure for example will affect the riveted joint effect, reduces driving torque, thus affect two structures in conjunction with effect.Although with anti-slip tank, use effect unsatisfactory behind the Insert Nut shade that has now; In addition, although the hexagonal Insert Nut has overcome problem, it is cumbersome to hole.

Summary of the invention

The utility model provides a kind of anti-skidding Insert Nut effective, that driving torque is large of riveting to the problems referred to above.

The technological scheme that provides according to the utility model: a kind of anti-skidding Insert Nut, comprise columnar riveting body and be arranged on the shade of described riveting body one end, be disposed with the first coaxial endoporus and the second endoporus by described shade to the other end in the described riveting body, the internal diameter of described the second endoporus is less than the internal diameter of described the first endoporus, and be provided with screw thread in described the second endoporus, be provided with a plurality of outstanding antislip bodies on the interior edge face of described shade.

Described a plurality of antislip body annular is distributed on the interior edge face of described shade.Described antislip body is hemispherical.Described antislip body has four.

Technique effect of the present utility model is: the utility model is provided with a plurality of outstanding antislip bodies at the interior edge face of shade, and during riveted joint, antislip body tightly is pressed in the riveted joint thing, strengthened Insert Nut and riveted joint thing in conjunction with effect, can greatly improve driving torque.

Description of drawings

Fig. 1 is overall structure schematic representation of the present utility model.

Fig. 2 is the worm's eye view of Fig. 1.

Fig. 3 is working state schematic representation of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

Among Fig. 1 ~ Fig. 3, comprise shade 1, the first endoporus 2, riveting body 3, the second endoporus 4, antislip body 5, riveted joint thing 6 etc.

As shown in Figure 1 and Figure 2, the utility model is a kind of anti-skidding Insert Nut, comprises columnar riveting body 3 and is arranged on the shade 1 of riveting body 3 one ends.

Be disposed with the first coaxial endoporus 2 and the second endoporus 4, the first endoporus 2 and the second endoporus 4 at riveting body 3 interior formation through holes by shade 1 to the other end in the riveting body 3, the internal diameter of the second endoporus 4 is less than the internal diameter of the first endoporus 2.The first endoporus 2 is unthreaded hole, is provided with screw thread in the second endoporus 4,

The utility model is provided with a plurality of outstanding antislip bodies 5 at the interior edge face of shade 1.A plurality of antislip body 5 annulars are distributed on the interior edge face of shade 1.Being shaped as of antislip body 5 is hemispherical, and quantity is four.

As shown in Figure 3, when the utility model used, riveted holes was opened at corresponding position on riveted joint thing 6, again with shade 1 facing to the riveting gun double-screw bolt, then screw in clockwise the riveting gun double-screw bolt, until the exterior edge face of riveting along 1 contacts with the stake outer wall.After connection is finished, riveting gun is passed riveted holes together with Insert Nut, and the interior edge face of shade 1 is contacted with the outer wall of riveted joint thing 6, spur at last riveting gun, after Insert Nut is subject to axial force, the first endoporus 2 has been extruded drum, and to extending all around, the hemispherical antislip body 5 that shade 1 interior edge face is special simultaneously is under the effect of axial compression power, make antislip body 5 be pressed into riveted joint thing 6, it is fully contacted, play skidproof effect, thereby greatly improved driving torque.

The utility model can adopt the material manufacturing of differing texture, and using scope can expand to the riveted joint of any object.The utility model intensity is high, good rigidity, and driving torque is large, and anti-seismic performance is strong, is applicable to machinery, vessel, the riveted joint of automobile and aeronautical material, safe and reliable.
