A quick connection device with an open container body and a sealing cap

Abstract

The invention discloses a quick connection device for a container body with an opening and a sealing cover, which comprises a joint bolt, a locking hook and a nut. One end of the joint bolt is integrally formed with a The hinged and fixed lifting ring, the other end of the swing bolt is provided with an external thread that can be screwed and fixed with the nut, the locking hook is slidably fitted on the swing bolt, and the locking The hook is correspondingly provided with a locking hook head that can be hooked and fixed with the flange on the container body or the sealing cover, and the nut is screwed on the swing bolt, and forms the shaft of the locking hook correspondingly. Fixed to the limit. Adopting the above-mentioned structure, not only can realize the fast loading and unloading connection between the sealing cap and the opening end of the container body, but also relatively reduce the processing steps, and will not affect the rigidity of the flange that cooperates with the locking hook, so that people do not need to increase the The thickness of the flange can achieve the purpose of saving materials.

Description

technical field [0001] The invention relates to a quick connection device, in particular to a quick connection device capable of quickly assembling a sealing cap on an opening of a container body with an opening. Background technique [0002] At present, most of the container bodies with openings and the sealing caps are connected by flanges, that is, corresponding flanges are first provided on the open end of the container and the sealing cap, and then openings for bolts to pass through are provided on the corresponding flanges. Bolts through holes, and finally locked and fixed by bolts and nuts. This structure of the prior art not only makes the opening and closing of the sealing cover on the opening of the container body need to disassemble many bolt groups, which seems very troublesome (that is, when the sealing cover is opened every time, all bolts on the flange need to be removed first). The nut is completely loosened and unscrewed from the bolt, and then the bolt is ...

AI Technical Summary

Problems solved by technology

This structure of the prior art not only makes the opening and closing of the sealing cover on the opening of the container body need to disassemble many bolt groups, which seems very troublesome (that is, when the sealing cover is opened every time, all bolts on the flange need to be removed first). The nut is completely loosened and unscrewed from the bolt, and then the bolt is pulled out; after the sealing cover is covered, the bolt needs to be reinserted, the nut is installed, and tightened), and because the bolt through hole is opened, the corresponding method will be greatly reduced. The rigidity of the flange itself, in order to improve the rigidity of the flange, it is usually necessary to greatly increase the thickness of the flange, which in turn causes a waste of material for the flange
