Abstract
The utility model relates to a stop nut belongs to machinery. The utility model discloses a hexagon nut, round boss, hexagon nut is located non - fastening end, and round boss is located the fastening end, and is threaded in the hexagon nut. The round boss head front end face is the conical surface, the hole is fluted. The universal connecting device of the flexible shaft has a simple structure and is convenient in use. When appearing slightly becoming flexible because of reasons such as vibration and slips between the ridge of bolt and nut, elastic deformation power still exists to guarantee that the friction self -locking action between the ridge is still effective, reach locking purpose.
Description
Technical field
This utility model relates to a kind of stop nut, belongs to mechanical field.
Background technology
Bolt and nut fastening is to be connected between mechanical field part and part and fasten modal connected mode, and bolts and nuts ensure the fastening connected by the friction self-locking effect between ridge.The change of the working conditions such as mechanical vibration in engineering reality, the creep failure of material, stress relaxation and material corrosion all may cause loosening of bolt and nut, even occurs nut to come off, brings safety problem and accident.Common anti-loose method has increase spring washer, elastic washer, lock washer and stop washer etc..The method installing packing ring additional meets different requirements by the various combination of selection bolt, packing ring and nut, and the deficiency existed is that the selection correctness to packing ring is heavily dependent on experience and Professional knowledge.
Summary of the invention
This utility model provides a kind of stop nut, for solving bolted loosening problem.
The technical solution of the utility model is: a kind of stop nut, including hex nut 11, circular bosses 12；
Described hex nut 11 is positioned at non-fastening end, and circular bosses 12 is positioned at fastening end, has screw thread 15 in hex nut 11.
Described circular bosses 12 head front end face is the conical surface 13, endoporus fluted 14.
Operation principle of the present utility model is:
When fastening nut, the circular bosses 12 front end conical surface 13 withstands connected piece surface, and elastic deformation occurs at circular bosses 12 endoporus groove 14, and whole circular bosses 12 caves inward so that remain with the presence of certain elastic force between connected piece surface and nut；When threaded because of vibration and slide occur loosen time, elastic deformation force can compress connected piece to a certain extent, play locking effect.
The beneficial effects of the utility model are: simple in construction, easy to use；Between the ridge of bolts and nuts because of vibration and the reason such as slip occur slightly loosening time, elastic deformation force there is also, thus ensures that the friction self-locking effect between ridge is also effective, reaches locking purpose.

Detailed description of the invention
Embodiment 1: as Figure 1-4, a kind of stop nut, including hex nut 11, circular bosses 12；
Described hex nut 11 is positioned at non-fastening end, and circular bosses 12 is positioned at fastening end, has screw thread 15 in hex nut 11.
Described circular bosses 12 head front end face is the conical surface 13, endoporus fluted 14.
Embodiment 2: as Figure 1-4, a kind of stop nut, including hex nut 11, circular bosses 12；
Described hex nut 11 is positioned at non-fastening end, and circular bosses 12 is positioned at fastening end, has screw thread 15 in hex nut 11.
Embodiment 3: as Figure 1-4, a kind of stop nut, including hex nut 11, circular bosses 12；
Described hex nut 11 is positioned at non-fastening end, and circular bosses 12 is positioned at fastening end, has screw thread 15 in hex nut 11.
Described circular bosses 12 head front end face is the conical surface 13, endoporus fluted 14.
As it is shown on figure 3, utilize stop nut and bolt 2 A connected pieces 3 and B connected piece 4 to tighten up.
As shown in Figure 4, the circular bosses 12 head stress deformation of stop nut when bolt is tightened, profile becomes profile shown in 1'.
Above in conjunction with figure, detailed description of the invention of the present utility model is explained in detail, but this utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art are possessed, it is also possible on the premise of without departing from this utility model objective, various changes can be made.
