Abstract

The invention provides a suspension system of a cryostat. The suspension system comprises fixed blocks, suspension matching elements and a pull ring, wherein the fixed blocks are fixed on an internal container of a compact cryostat, first side surfaces of the suspension matching elements are connected with a corresponding first end of the pull ring, second side surfaces of the suspension matching elements are connected with the fixed blocks in a matching way so that a rotatable rotation pair is formed between the suspension matching elements and the fixed blocks, and a second end of the pull ring is connected with an external container of the compact cryostat. The suspension system is easy to manufacture and use and is provided with an assembly structure with an automatically-adjustable angle, the suspension pull ring can be prevented from being deformed in an S shape, the bending stress is eliminated, and the service lifetime of the pull ring is prolonged; meanwhile, a fixed and connection structure used for the compact cryostat is small in volume, the requirement of the compact cryostat can be met; and moreover, a fixed and bearing structure is good in a stress state and high in bearing capability.

Description

technical field [0001] The invention relates to a suspension system for a multi-layer thermal insulation container, in particular to a suspension system for a cryostat. Background technique [0002] In a compact cryostat, conventional superconducting magnets usually inject a large amount of liquid helium into the cryostat to soak the coils and keep the coils in a low-temperature superconducting state. figure 1 It is a schematic diagram of the structure of a traditional cryostat. like figure 1 As shown, the cryostat adopts a multi-layer container, in which the low-temperature inner container 10 contains a low-temperature medium, and at least one layer of shielding for reflecting heat radiation is arranged in the cavity between the inner container 10 and the outer container 20 The layer 30, the inner container 10 and the shielding layer 30 are completely suspended from the outer container 20 firmly by the supports 40, which are generally rods or rods with a large aspect rati...
