Detailed description of the invention

The invention is further described with reference to the following examples and the accompanying drawings.

As shown in fig. 1 and 2, a high contact rigidity altitude mixture control fastener, including bolt 8 and fixed mounting bear post 2 on fixed flat board 1, bear the post 2 and go up the cover and be equipped with adjusting nut 3, adjusting nut 3 upper end is equipped with first spherical gasket 4, and first spherical gasket 4 upper end is equipped with by connecting device 5, is equipped with clamping ring 6 by connecting device 5 upper end, and clamping ring 6 upper end is equipped with second spherical gasket 7, clamping ring 6 are passed in proper order to bolt 8's one end, by connecting device 5, first spherical gasket 4, adjusting nut 3 and bear post 2 fixed connection, between adjusting nut 3 and the first spherical gasket 4, the contact surface between clamping ring 6 and the second spherical gasket 7 is the equal radius sphere.

The adjusting nut 3 is sleeved on the bearing column 2 through a fine thread pair, and the distance between the connected equipment 5 and the fixed flat plate 1 can be adjusted by rotating the adjusting nut 3.

The lower end of the bearing column 2 is fixedly connected with the fixed flat plate 1 through a flange structure.

A bearing column 2, an adjusting nut 3 and a first spherical gasket 4 are arranged between the flange position of the connected device 5 and the fixed platform 1, the bearing column 2 and the adjusting nut 3 are connected through a fine thread pair, and the distance between the connected device 5 and the fixed platform 1 can be adjusted by rotating the adjusting nut 3. The contact surface between adjusting nut 3 and first spherical gasket 4, between clamping ring 6 and the second spherical gasket 7 is the equal radius sphere for whether parallel by jointing equipment 5 and fixed platform 1 in the adjustment process, be face contact between each part of this device all the time, bolt 8 passes adjusting part and is fastened it together by jointing equipment.
