Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: overcoming the deficiencies of the prior art, providing an integrated heat - resistant and load - bearing spherical detector structure, providing a reliable working platform for detection instruments and equipment, and meeting the needs of near - space environment detection.

[0005] Preferably, a threaded insert is pre - embedded in a circle at the open end of the left spherical head and the left side of the spherical column section. The left flange frame is provided with through - holes corresponding to the threaded inserts at the open end of the left spherical head and the threaded inserts on the left side of the spherical column section.

The assembly of the right spherical head, the right flange frame, and the spherical column section is completed by the cooperation of external bolts with the stepped holes and the threaded holes.

[0007] Preferably, the stepped holes are in an exposed state. After the assembly is completed, heat - resistant putty material is poured to fill them.
