With the development of science and technology and the improvement of energy-saving and environment-friendly consciousness, new requirements are continuously put forward on the related fastening connection of mechanical equipment and tools in the fields of aerospace, traffic, electronics, photovoltaic, new energy industries and the like; however, the existing fastener is matched with a single helical surface in rigidity, so that the bolt, the thread of the bolt and a connected piece are damaged due to large pretightening force and uneven thread stress, particularly, in threaded connection in the environment with vibration machinery and wind power and large temperature difference, a shockproof and antiskid accessory device must be additionally arranged, and when the special requirements of precise and safe threaded connection exist, the requirements on the material and the manufacturing process of the bolt and the hexagon nut are particularly high; in addition, for equipment with light weight requirements, the fastening piece cannot be realized at present, and for the fastening piece with sealing requirements, the adhesive dispensing treatment is often carried out, so that not only is the risk that the adhesive dispensing is easy to age and lose effectiveness under external force, but also the assembling and disassembling difficulty of installation and maintenance is brought.
Therefore, it is desirable to develop a seal spring nut assembly that solves the above problems.
Disclosure of Invention
The invention aims to provide a sealing spring nut assembly, and provides a spring nut and an external sealing shell which are manufactured by a deep drawing and stamping forming technology, which not only do not influence the anti-loose fastening function of the spring nut, but also can effectively seal a fastener and a connecting piece, and keep the light weight characteristic of the spring nut so as to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: sealing spring nut subassembly, including sealed shell and spring nut, sealed shell internally mounted has spring nut, its characterized in that: the improved spring nut structure is characterized in that a sealing shell hemispherical head is arranged at the top end of the sealing shell, a first transition circular arc is arranged at the bottom end of the sealing shell hemispherical head, a second transition circular arc is arranged at the bottom end of the first transition circular arc, a hexagonal transition cavity body is fixedly connected to the bottom end of the second transition circular arc, a third transition circular arc is arranged at the bottom end of the hexagonal transition cavity body, a forming riveting cambered surface is arranged at the bottom end of the third transition circular arc, a spring ring is arranged at the top end of the spring nut, six supporting bodies are fixedly connected to the bottom ends of the spring nut, and the bottom ends.
Preferably, the hemispherical head inner cavity space can accommodate at least two thread pitches of the bolt rail.
Preferably, the size of the inner circle of the truncated cone-shaped hollow circular ring formed after the hollow cylinder of the sealing shell is riveted on the spring washer of the spring nut is larger than the maximum outer diameter of the spring nut which needs to be installed in the sealing shell and contains the spring washer, so that elastic deformation of the sealing spring nut in the fastening and connecting process is met.
The invention has the technical effects and advantages that:
the invention integrates the sealing shell and the spring nut by arranging the sealing shell, the hemispherical head of the sealing shell, the first transition arc, the second transition arc, the third transition arc, the forming riveting arc surface, the hexagonal transition cavity body, the spring nut, the spring ring, the thread major diameter vertex of the spring nut and the six-sided support body, thereby reducing the number of parts, facilitating the fastening, the connection, the disassembly and the assembly, having simple structure and strong universality, being compliant with the elastic deformation of the spring nut without fracture, having the same durable sealing effect as the use of the spring, having simple manufacturing process, light weight and low cost.
