Spiral compaction sealing type quick-opening device

Abstract

The invention discloses a spiral compaction sealing type quick-opening device. The spiral compaction sealing type quick-opening device mainly comprises a container main body, a quick-opening end cover part and a seal assembly, wherein a boss and container main body meshing teeth are sequentially machined on an end flange of the container main body from inside to outside of the container main body, the boss is provided with a groove, and the meshing surface of the container main body meshing teeth is a spiral surface with a certain lead angle; the quick-opening end cover part mainly comprises an end cover, end cover meshing teeth, a support, a guide shaft and a torsion shaft, the end cover meshing teeth and the container main body meshing teeth can form similar thread connection matching, a cover plate can move along the axial direction by being rotated anticlockwise, a sealing element is compacted, and zero clearance between the cover plate and the boss of a container is guaranteed. A spiral compaction mechanism is designed on the basis of a tooth-locked quick-opening structure, and sealing of the container is realized through mechanism self-adaption; meanwhile, quick opening of the end cover is guaranteed, and the spiral compaction sealing type quick-opening device is compact in structure and convenient to operate, and has good engineering application prospects.

Description

technical field [0001] The invention relates to a device for realizing quick opening and closing, in particular to a screw compression and sealing type quick opening device. Background technique [0002] Anti-explosion containers play a very important role in the field of public safety. They can effectively limit or suppress the destructive effects of explosives and ensure the safety of people and public property. Due to the particularity of the usage scenarios, in addition to meeting the basic protection requirements, the explosive container also needs to have the characteristics of convenient and fast operation. The toothed quick-opening mechanism can better meet the above requirements, so it is widely used in the design of anti-explosion containers. However, the principle of use of the toothed end cap determines that there must be a gap in the contact between the meshing teeth, because if there is no gap or the gap is small, the operation will be difficult, and the inher...

Problems solved by technology

However, the principle of use of the toothed end cap determines that there must be a gap in the contact between the meshing teeth, because if there is no gap or the gap is small, the operation will be difficult, and the inherent gap will be very unfavorable for the suppression of the explosion damage effect. In the test In the process, we found that there will be shock waves and flames rushing out of the gap of the end cover. This situation will bring great inconvenience and even danger in actual scientific research and production.
