Embodiment Construction

[0039] The invention will be further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention.

[0040] Please refer to Figure 1-3 , Embodiment 1 of the present invention will be described below.

[0041] like figure 1 As shown, the present invention provides a self-locking nut for a sealing pallet, which includes a self-locking nut 1 for a pallet and a bottom gasket 2 made of metal.

[0042] The two sides of the pallet nut are provided with ear-shaped flanges for assembling and fixing, and each of the symmetrically distributed ear-shaped flanges has a bolt through hole for assembling.

[0043] The top of the support plate self-locking nut is closed, and the inner self-locking threaded hole is a blind hole, which can not only prevent the sealing material from being exposed to the outside, but also has better sealing and pressure resistance capability.

[0044] The bottom of the self-locki...

Abstract

The invention provides a sealing supporting plate self-locking nut. The sealing supporting plate self-locking nut comprises a supporting plate self-locking nut body and a sealing gasket installed on the bottom face of the supporting plate self-locking nut body, wherein bolt via holes are formed in flanges on the two sides of the supporting plate self-locking nut body, and a self-locking threaded hole is formed in the middle of the bottom face of the supporting plate self-locking nut body. The sealing supporting plate self-locking nut is characterized in that the sealing gasket is oval or in ashape similar to an oval, and the long axis of the sealing gasket coincides with the connecting line of the two bolt via holes. The sealing pressure resistance is improved by enlarging the sealing area of the sealing gasket, and the edge of the sealing gasket is prevented from making direct contact with the external environment through a sealing gasket counter bore or a flange on the edge of the bottom face of the supporting plate self-locking nut body. Higher sealing pressure resistance is obtained, and meanwhile the sealing supporting plate self-locking nut has better ageing resistance compared with the prior art.

Description

technical field [0001] The invention belongs to the field of mechanical fasteners, in particular to an airtight pallet self-locking nut. Background technique [0002] In modern production and manufacturing, especially in the fields of aerospace and other fields that have high airtight requirements for mechanical assembly, the requirements for airtight performance and anti-aging performance are getting higher and higher. Airtight binoculars commonly used in the existing machinery industry The pallet self-locking nut GB933-1988 has the following problems in the application process of the aviation field: [0003] 1. The sealing material is exposed to the outside for a long time. In the air or in a complex use environment, it often ages and falls off, causing the installation site to fail to seal. [0004] 2. The manufacturing process is not good. During the manufacturing process of the sealing material, the thread and the bottom of the hole are prone to accumulation of the sea...
