Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides an embodiment: light nut for aviation, including end 1, internal thread 5 and tail end 8, the appearance of end 1 sets up to the hexagonal structure, the same as conventional hexagon nut appearance, facilitate the screwing nut, the outer wall of end 1 has bar groove 2, bar groove 2 has 6 groups, set up in the middle position of the outside surface of end 1 separately, bar groove 2 is distributed in the annular array, and the sectional shape of bar groove 2 is isosceles triangle, facilitate the insertion of the flaky tool, increase the installation method, make the practicability strengthened, the front of end 1 has caulking groove 3 concentrically, and the cavity of caulking groove 3 has 3 groups of spread grooves 4, the cavity of caulking groove 3 has rubber gasket 6, the thickness of rubber gasket 6 is greater than the thickness of caulking groove 3, as shown in figure 2, when screwing up the bolt, because the thickness setting of rubber gasket 6, rubber gasket 6 contacts with the connecting piece at first, when continuing to twist, can not cause the fish tail to the connecting piece, when rubber gasket 6 was extruded the certain degree, rubber gasket 6 was filled the gap between end 1 and the connecting piece to make the leakproofness between nut and the connecting piece strengthen, strengthen the practicality, rubber gasket 6's the back is provided with spliced pole 7, spliced pole 7 is connected with spread groove 4, inserts spread groove 4 through spliced pole 7 inside, thereby makes and forms the installation between rubber gasket 6 and the caulking groove 3.

The rear end of the end 1 is provided with a tail end 8, the appearance of the tail end 8 is provided with a cylindrical structure, the shape of the tail end 8 is changed, and by combining the figures 2 and 4, it can be seen that the tail end 8 has different appearances, so that the whole volume of the nut is reduced, and the material of the nut is reduced, the end 1 and the tail end 8 are of an integral structure, the production is convenient, the outer wall of the tail end 8 is provided with square grooves 9, the square grooves 9 are provided with 2 groups, the square grooves 9 are symmetrically distributed at two ends of the tail end 8, as shown in figures 2 and 4, the square grooves 9 are arranged at two ends of the tail end 8, and the inner cavity of the square grooves 9 is of a rectangular structure, so that a tip tool can enter conveniently, the tail end 8 can be rotated conveniently, so that different installation is formed, the inner cavity of the end 1 and the inner cavity of the tail end 8 are both provided with internal threads, the outer wall of tail end 8 is provided with 2 sets of reinforcing ring 10, and reinforcing ring 10 welds the outer wall at tail end 8, plays certain reinforcing effect to tail end 8 to as can be seen from figure 4, the outer wall of reinforcing ring 10 is provided with the edges and corners, can rotate through twisting reinforcing ring 10, whole nut.

The working principle is as follows: during the use, at first overlap end 1 on the bolt as the front end, rotate the nut after that for the internal thread 5 of end 1 inside is connected with the external screw thread on the bolt, under the effect of external screw thread and internal thread 5, makes end 1 constantly to the bolt up-moving, and 8 inner chambers of tail end are provided with the internal thread 5 that links up with 1 inner chamber of end, and then 8 covers also on the bolt of tail end.

Because end 1 and tail end 8 different appearance structural design for the material of nut reduces, end 1 and tail end 8 formula structure as an organic whole, convenient production, lighter, end 1 and tail end 8 are stable structure simultaneously, and intensity can obtain guaranteeing, makes the holistic quality of nut reduce, has strengthened the practicality.

When inconvenient use spanner is installed, because be provided with bar groove 2 and square groove 9 on end 1 and the tail end 8 respectively, can adopt slice instrument or tip instrument to install, increased the mounting means of nut, convenient and practical more.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
