Quick connecting device with open container body and sealing cover

Abstract

The invention discloses a quick connecting device with an open container body and a sealing cover. The quick connecting device comprises a swing bolt, a locking hook and a nut; a ring which can be fixedly hinged to the container body or the sealing cover is integrally formed on the end part of one end of the swing bolt; the end part of the other end of the swing bolt is provided with external threads which can be fixedly spirally connected with the nut; the locking hook sleeves the swing bolts in a sliding manner, and is correspondingly provided with a locking hook head which can be fixedly matched with a flange on the container body or the sealing cover; the nut is spirally connected to the swing bolt, and the axial limiting fixation to the locking hook is correspondingly formed. By adopting the structure, the sealing cover and the open end of the container body are quickly detached and connected, processing procedures are relatively reduced, and the rigidity of the flange matched with the locking hook head cannot be influenced, so that the thickness of the flange is not required to be increased, and the aim of saving materials is fulfilled.

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
