Description

Technical Field

[0001] The utility model relates to the field of aerospace, in particular to a high-pressure outer sleeve nut for aerospace. Background Art

[0002] The aircraft jacket joint nut is a jacket joint nut used on aircraft. The jacket street nut refers to a nut with a thread arranged on the outside, usually in a straight line or an L shape. It is usually used to connect oil pipes, water pipes, etc., and is one of the commonly used nuts. However, the existing aircraft jacket joint nuts have certain shortcomings that need to be improved; the existing aircraft jacket joint nuts have certain disadvantages when used. First, when installing the jacket joint nut, people need to manually put on a gasket for sealing and rust prevention, which is usually made of rubber. In a large amount of installation work, each jacket joint nut needs to be installed with a gasket, which increases the cumbersomeness of the work, and it is also easy to forget that the missing part is not installed, which will affect the sealing effect.

[0003] According to the published patent 201821887357.6, a jacket joint nut for aircraft includes a connecting block, a first connecting end is embedded and installed on the upper part of the connecting block, a second connecting end is embedded and installed on one side of the connecting block, a first gasket is provided on the outer side of the upper part of the connecting block and the first connecting end, and the first gasket is fixedly connected to the connecting block through a tie rod, a second gasket is provided on the outer side of the second connecting end on one side of the connecting block, and the first connecting end and the second connecting end are internally connected. The utility model discloses a jacket joint nut for aircraft, which is provided with a first gasket, a tie rod and a guide strip. Firstly, it can save working steps and also avoid the phenomenon of people missing the installation gasket. Secondly, when the liquid enters the turning point, it can flow out from the other end in a vortex shape in an orderly manner. Compared with the traditional method of directly colliding with the inner wall of the turning point, it saves a lot of flow energy and brings better use prospects. In the process of realizing the utility model, the inventor found that at least the following problems exist in the prior art and have not been solved. Although the first gasket and the tie rod are set, the first gasket is fixed to the connecting block by the tie rod and is sleeved on the outside of the first connecting end, so the first gasket and the connecting block are fixedly connected, people do not need to sleeve a gasket separately when using it, which saves working steps and also avoids the phenomenon of people missing the installation gasket. The existing aircraft jacket joint nuts have certain shortcomings that need to be improved; the existing aircraft jacket joint nuts have certain drawbacks when in use. First, when installing the jacket joint nuts, people need to manually put on the gaskets for sealing and rust prevention, which are usually made of rubber. In a large number of installation works, each jacket joint nut needs to be installed with gaskets, which increases the cumbersomeness of the work, and it is easy to forget that the missing part is not installed, which will affect the sealing effect. However, during use, the traditional aerospace high-pressure jacket nuts still need to fix the gaskets with the connecting blocks through tie bars, which causes the tie bars to break easily during the use of the gaskets, resulting in the loosening and displacement of the gaskets. Moreover, the existing high-pressure jacket nuts cannot promptly notify the staff when loose problems occur during use. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a high-pressure outer sleeve nut for aerospace use to solve the problem that the current traditional aerospace high-pressure outer sleeve nut still needs to fix the gasket to the connecting block through tie rods, which causes the tie rods to break easily during the use of the gasket, causing the gasket to loosen and move. Moreover, the existing high-pressure outer sleeve nut cannot promptly notify the staff when it becomes loose during use.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a high-pressure outer shell nut for aerospace, including a hexagonal screw sleeve, and also including:

[0006] Two gasket bodies are integrally formed at the front and rear ends of the hexagonal screw sleeve;

[0007] The induction mechanism is provided at one end of the gasket body, which can not only set the gasket in an integrated manner, thereby eliminating the need for repeated sleeve installation of the gasket, but also a sensing structure is provided on the surface of the gasket, which can prevent the high-pressure jacket nut from loosening. The integrated gasket mechanism includes a plurality of circular grooves, and the plurality of circular grooves are provided at one end of the gasket body;

[0008] Wireless pressure sensors are installed inside the plurality of circular grooves.

[0009] Preferably, an annular groove is formed at one end of the gasket body, and water-swellable waterproof cotton is fixed inside the annular groove.

[0010] Preferably, a nut body is integrally formed inside the hexagonal screw sleeve, and a threaded wall is formed on the inner wall of the nut body.

[0011] Preferably, six sides of the hexagonal screw sleeve are all provided with slots.

[0012] Preferably, a protective net is fixed on one side inside each of the six card slots.

[0013] Preferably, DFC isolation cotton is fixed on the other side of the six card slots.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model combines a gasket body, a hexagonal screw sleeve and a wireless pressure sensor, and utilizes the integral molding of the gasket body (metal gasket) and the hexagonal screw sleeve, which not only saves the installation of the gasket, but also saves the installation of the tie rod. The direct integral molding increases the stability of the gasket body, and a plurality of wireless pressure sensors are arranged on the surface of the gasket body. When the connection between the pipeline and the high-pressure jacket nut becomes loose, the pressure of the wireless pressure sensor will change. When the wireless pressure sensor is connected to the terminal of the staff, the staff can be directly notified, which solves the technical problem that the traditional aerospace high-pressure jacket nut still needs to fix the gasket to the connecting block through the tie rod, which causes the tie rod to break easily during the use of the gasket, resulting in the loosening and displacement of the gasket. Moreover, the existing high-pressure jacket nut cannot promptly notify the staff when it becomes loose during use.

[0016] 2. The utility model combines an annular groove, water-swellable water-stopping cotton and DFC isolation cotton, which not only can arrange water-swellable water-stopping cotton on the surface of the gasket body, so that the water-swellable water-stopping cotton can quickly expand when encountering water, and can seal the connection position between the pipeline and the high-pressure outer sleeve nut. At the same time, multiple DFC isolation cottons are arranged in the hexagonal screw sleeve, and the moisture outside the high-pressure outer sleeve nut can be absorbed through the multiple DFC isolation cottons to avoid the high-pressure outer sleeve nut from getting damp, and after the DFC isolation cotton is saturated, it can actively discharge water.
