Technical Field

[0001] The utility model relates to the technical field of telescopes, in particular to a telescopic embedded variable truss structure. Background Technique

[0002] Space telescopes, also known as space telescopes, are one of the main observation tools for astronomers. Most optical telescopes used in astronomy use a large curved mirror instead of a lens to focus. Space telescopes can ensure that sensitive detectors can collect light emitted from distant stars to the maximum extent, while lenses will absorb a part of the light when it passes through.

[0003] The secondary mirror module is one of the components of a space telescope. The secondary mirror module needs to cooperate with a corresponding truss when in use. However, the existing trusses are generally fixed to the primary mirror module and the secondary mirror module through bolts, resulting in troublesome installation and disassembly. Therefore, it is necessary to design and transform the telescopic embedded variable truss structure to effectively prevent the phenomenon of inconvenient disassembly and assembly. Content of the Utility Model

[0021] Referring to Figure 1 and Figure 4 , the locking assembly 9 includes a drive box 10 fixedly connected to the surface of the secondary mirror assembly 2. The number of drive boxes 10 is four. A left - hand and right - hand threaded rod 11 is movably connected inside the drive box 10. A turning handle is fixedly connected to the surface of the left - hand and right - hand threaded rod 11. Locking frames 12 are threadedly connected to both sides of the surface of the left - hand and right - hand threaded rod 11. The locking frames 12 are movably connected to the drive box 10. A through - opening 13 is formed on the surface of the square frame 8. The through - opening 13 is movably connected to the locking frame 12.

[0022] As a technical optimization solution of the present invention, through the setting of the locking assembly 9, the operator can rotate the turning handle to drive the left - hand and right - hand threaded rod 11 to rotate, thereby driving the locking frames 12 on both sides inside the drive box 10 to approach each other, so that the locking frames 12 are inserted into the through - opening 13, thereby locking the position of the square frame 8.

[0023] Referring to Figure 1 and Figure 4 , a bearing is fixedly connected inside the drive box 10, and the bearing is fixedly connected to the left - hand and right - hand threaded rod 11. Lubricating oil is arranged inside the bearing, and a sealing shaft cover is arranged inside the bearing.

[0024] As a technical optimization solution of the present utility model, through the arrangement of the bearing, the friction between the drive box 10 and the left - hand and right - hand threaded rod 11 can be reduced, thereby facilitating the rotation of the left - hand and right - hand threaded rod 11.
