Description
Technical Field
The invention belongs to the field of mechanical design and manufacture, and particularly relates to a supporting plate self-locking nut.
Background
The standard component is an important component of an aviation product, and has very important significance for shortening the design and manufacturing period of the product, reducing the production cost and improving the product quality.
The existing sealing support plate nut structure is shown in fig. 1 and fig. 2 and consists of a support plate nut and a wrapping rubber cover, or a nut body, a metal sealing outer cover and a sealing ring. FIG. 1 illustrates a supporting plate nut and a wrapped rubber cover, wherein the cover body is damaged by riveting, the amount of movement is lacked, the assembly manufacturability is poor, the rubber cover is easy to age, and the service life is short; the nut shown in fig. 2 has large installation space, is easy to rivet the cover body and has heavy weight.
Disclosure of Invention
The purpose of the invention is as follows: the self-locking nut of the floating sealing supporting plate is easy to install.
The technical scheme of the invention is as follows:
a pallet self-locking nut comprising:
a nut body 1 and a retainer 2;
the top of the nut body 1 is provided with a metal cover 3, a middle part 4 of the nut body is internally provided with threads, and a lower bearing surface 5 of the nut body;
the retainer 2 is sleeved on the nut body 1, and two ends of the retainer are fixed with the structural part.
The bearing surface of the bottom of the nut body 1 is provided with a groove 6, and a sealing ring 7 is arranged in the groove 6.
The back side of the lower bearing surface is provided with a bulge 8 for limiting the retainer 2.
The retainer 2 consists of three conjoined rings.
The rings 9 at the two ends of the retainer 2 are small in diameter, the two rings 9 are flush, and the middle ring 10 is large in diameter.
The middle ring 10 of the retainer 2 bulges towards one side of the nut.
The invention has the beneficial effects that:
the fixed mounting manufacturability is good, and the nut is removable, has solved the ageing problem of rubber, and seal structure is more advanced than original rubber cladding's metal ears seal carrier self-locking nut, improves the maintenance and changes the aspect nature, has alleviateed weight, promotes domestic aviation standard component technical progress.
The mounting, maintenance and dismounting technology is universal with the existing supporting plate nut mounting, maintenance and dismounting technology; the structure form is simple, and the cost and the weight are not increased; the requirement of long service life of the modern airplane is met; the requirement of model development is met, and the technical progress of the domestic aviation standard component is promoted.

Detailed Description
The invention provides a self-locking nut of a movable sealing supporting plate, which consists of a nut body with a sealing ring and a retainer, wherein the nut body consists of a metal shell with internal threads, the upper part of the shell is closed, namely a blind end, the blind end is provided with internal threads, the lower part of the shell is provided with a flange surface, a groove is formed on the flange surface, the sealing ring is embedded in the groove, and the back side of the flange surface is convexly stuck; the retainer consists of 3 conjoined rings, two short rings are used for fixing and installing the nut, and the middle ring is larger and irregular and is used for keeping the nut body.
The technical scheme of the invention is as follows: the outer surface of the nut body extends upwards and converges into a closed space to form a part of the sealing shell, the outer surface of the nut body extends downwards and outwards to form a large circular ring, the interface of the circular ring becomes a bearing surface, a circular groove is carved on the bearing surface, a sealing ring is embedded in the circular groove, the nut compresses the sealing ring to be tightly attached to the structure, and the sealing ring and the outer surface of the nut form a sealing cavity to realize the sealing function. The outer surface of the large circular ring of the nut body is additionally provided with bulges, the retainer is embedded into the large circular ring, and the supporting plate holding function of the nut is realized by adopting small rings which are riveted at two ends of the retainer in the prior art. The layer board of traditional layer board nut is provided by the structure of installation layer board nut, and the layer board provides for the three rings of wire rod or silk material structure to the holding function of nut, simplified structure to weight reduction, realization assembly.
Examples
As shown in fig. 3, 4 and 5, the floating seal pallet self-locking nut comprises:
a nut body 1 and a retainer 2;
the top of the nut body 1 is provided with a metal cover 3, a middle part 4 of the nut body is internally provided with threads, and a lower bearing surface 5 of the nut body;
the retainer 2 is sleeved on the nut body 1, and two ends of the retainer are fixed with the structural part.
The bearing surface of the bottom of the nut body 1 is provided with a groove 6, and a sealing ring 7 is arranged in the groove 6.
The back side of the lower bearing surface is provided with a bulge 8 for limiting the retainer 2.
The retainer 2 consists of three conjoined rings.
The rings 9 at the two ends of the retainer 2 are small in diameter, the two rings 9 are flush, and the middle ring 10 is large in diameter.
The middle ring 10 of the retainer 2 bulges towards one side of the nut.
