Abstract
A sealing structure for a Stirling cooler includes a bellows, a first connecting block disposed at an end of the bellows, and a second connecting block disposed at another end of the bellows. The sealing structure for a Stirling cooler can generate both off-axis movements and lateral movements so as to produce corresponding harmonic motions, such that vibrations can be isolated, excellent vacuum can be obtained, and superior sealing quality can be ensured. Thereupon, possible leakage for the Stirling cooler operated under a significant pressure difference can be substantially resolved.

A sealing structure for a Stirling cooler, comprising:
- a bellows;
- a first connecting block, disposed at an end of the bellows;
- and
- a second connecting block, disposed at another end of the bellows.
A Stirling cooler, comprising:
- a cooling cylinder, having thereinside an expansion chamber, a displacer and a regenerator, the displacer being furnished outside to the regenerator, a cooling head being provided exterior to the cooling cylinder;
- and
- a compression cylinder, having thereinside a compression chamber, a connecting mechanism and a sealing structure for a Stirling cooler, the connecting mechanism connecting the sealing structure, the compression chamber being communicated spatially with the cooling cylinder, the sealing structure being connected with the regenerator, the sealing structure having a bellows, a first connecting block disposed at an end of the bellows, and a second connecting block disposed at another end of the bellows.
