Abstract

The invention discloses a low-pressure chamber connection throat structure. The low-pressure chamber connection throat structure is characterized by comprising a chamber door component (1), wherein an oil cylinder rod (2) is arranged below the chamber door component (1) and connected with an oil cylinder component (7); an airtight door frame (3) is arranged above the chamber door component (1); a fixed hook (4) for the chamber door component (1) is arranged on the side of the airtight door frame (3); a power ring (5) with a bump is arranged at the inner side of the fixed hook (4) and connected with a pneumatic rotary motor (6). The throat structure has the beneficial effects that: A, a power ring hook opening structure is adopted, so that synchronous opening of the hook is ensured; B, the opening power of the chamber door component is controlled by air pressure, so the reliability is high; the hydraulic cylinder mechanism in the structure can reset the chamber door and also can ensure stable opening of the chamber door; a buffer spring is arranged on the system, so that the chamber door does not rebound after buffer is started, the low-pressure chamber connection throat structure has a reliable sealing effect, is simple in structure, and fast to start, and can be repeatedly used.

Description

[0001] technical field [0002] The invention relates to a connecting throat structure of a low pressure cabin, belonging to the technical field of connection between a decompression simulation cabin and a negative pressure cabin. Background technique [0003] At present, the method of blasting glass between the decompression simulation cabin and the negative pressure cabin is used in the world to connect the two cabins to achieve the purpose of rapid decompression of the decompression cabin. The crushing mechanism is closely related, and the blasting time is not easy to measure and control, and the blasting time is unstable under the same external test conditions, which makes the test analysis results of the test organism or equipment during the rapid decompression process have time uncertainty. Contents of the invention [0004] The purpose of the present invention is to provide a low pressure cabin connecting throat structure. It can start blasting at high speed and ca...
