Abstract
The utility model discloses a self-locking nut with a sealing ring. The self-locking nut comprises a self-locking nut shell, wherein a nut groove of an internal thread is arranged on the self-locking nut shell; the self-locking nut is arranged inside the nut groove; a sealing ring groove is arranged at one end of the nut groove; the sealing ring is arranged inside the sealing ring groove; a blind hole for preventing liquid leakage is arranged at the bottom of the nut groove; a locking groove capable of locking the nut is arranged on the nut groove; and a pivoting hole which can be pivoted on a base through a bolt is arranged on the self-locking nut shell. Compared with the prior art, the self-locking nut has not only the advantages of being simple in structure and practical, but also the advantages of being smart in design, safe and reliable, long in service life and wide in application range, and the liquid or gas leakage is prevented, the service life of a nut assembly is prolonged, the cost is reduced, etc.
Description
Technical field
The utility model relates to a kind of self-locking nut, particularly a kind of self-locking nut with seal ring.
Background technique
At present, self-locking nut all plays important effect at important connection, sealing, the anti-loose assembling position in the fields such as Aeronautics and Astronautics, existing nut structure is the plate nut of whole encapsulate, and sealing place adopts silica gel as sealing, but silica gel suitable environment temperature difference and working life are short, and a lot of nuts directly contact with matrix phase, screw thread is short working life, often has liquids and gases seepage to occur, often change, increased cost, so prior art is still perfect not.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, practical, prevent the liquids and gases seepage, long service life, have wide range of applications, increase the working life of nut assembly self, reduced a kind of self-locking nut with seal ring of cost, to overcome the deficiencies in the prior art.
The utility model is constructed as follows: a kind of self-locking nut with seal ring, comprise the self-locking nut shell, and at the self-locking nut shell female nut groove is set, in nut groove, be provided with self-locking nut; End at nut groove is provided with seal groove, is provided with seal ring in seal groove, and the blind hole that can prevent fluid seepage is set in the bottom of nut groove, nut groove be provided with can locking nut locking slot; Be provided with and be riveted on riveted holes on the matrix by bolt at the self-locking nut shell.
Owing to having adopted technique scheme, at first the self-locking nut shell is riveted on the matrix during use, then nut is passed the bolt hole on the matrix, and the interior set screw nut of the nut groove that is inserted into the self-locking nut shell, seal ring is produced be out of shape, firmly be pressed in matrix surface, match with blind hole structure like this, play dual sealing functions; Compared with prior art, the utility model not only has simple in structure, practical advantage, and design ingenious, safe and reliable, prevent the liquids and gases seepage, long service life has wide range of applications, increases working life of nut assembly self, has reduced the advantages such as cost.

Description of reference numerals: 1-self-locking nut shell, 2-nut groove, 3-seal groove, 4-seal ring, 5-locking slot, 6-riveted holes, 7-self-locking nut, 8-blind hole, 9-matrix.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Enforcement of the present utility model: a kind of self-locking nut with seal ring, comprise self-locking nut shell 1, shown in Fig. 1～2, at self-locking nut shell 1 female nut groove 2 is set, in nut groove 2, be provided with self-locking nut 7; End at nut groove 2 is provided with seal groove 3, is provided with seal ring 4 in seal groove 3, and the blind hole 8 that can prevent fluid seepage is set in the bottom of nut groove 2, nut groove 2 be provided with can locking nut locking slot 5; Be provided with and be riveted on riveted holes 6 on the matrix by bolt at self-locking nut shell 1.
Seal ring 4 is selected the high temperature resistant or low temperature materials such as teflon (SFBN).
At first self-locking nut shell 1 is riveted on the matrix 9 during use, then self-locking nut 7 is passed the bolt hole on the matrix 9, and be inserted into the nut groove 2 interior set screw nuts of self-locking nut shell 1, seal ring 4 is produced be out of shape, firmly be pressed in matrix 9 surfaces, match with blind hole structure like this, play dual sealing functions.
After the assembling of this combination seal self-locking nut screw is not directly contacted with bolt with matrix phase, protected matrix and bolt (screw), play prolongation screw thread working life, increased the intensity that is threaded; Himself locking, double seal characteristics have increased the effects such as screw thread antidetonation, anti-loose, anti-fluid seepage, gas simultaneously; And locking position distortion particularity and practicability, in the working life of increase nut assembly self, reduced cost.
Except above-mentioned, according to the difference of assembling position situation, can change the structure at riveting dress position, can select the forms such as ears or band twisting, satisfy different assembling demands, application area is very extensive.
