Aiming at the defects of the prior art, the utility model provides a connecting device of a cargo compartment ventilation hatch cover and a degassing hose, which ensures that the degassing hose and the ventilation hatch cover are connected in a sealing way and cannot fall off.

In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a connecting device of cargo hold ventilation cabin cover and degasification hose, includes joint and clamp, the joint includes the connecting pipe, the bottom girth welding of connecting pipe has annular gland, annular gland terminal surface is provided with three clamp plate, and the contained angle is 120 between the adjacent clamp plate, and U type opening is seted up to the clamp plate outer end, U type opening corresponds with the butterfly nut of ventilation cabin cover, cup joint in the top outside of ventilation cabin cover annular gland bottom, the connecting pipe upper portion outside girth welding has the boss, the clamp cup joints in the boss below. The annular gland is sleeved at the upper part of the ventilation hatch cover, the outer side of the ventilation hatch cover is hinged with a bolt, the end part of the bolt is screwed with a butterfly nut, the bolt is clamped in the U-shaped opening, and the butterfly nut is tightly pressed on the pressing plate, so that the joint is tightly connected with the ventilation hatch cover; with the cover joint of degassing hose on the connecting pipe, degassing hose's tip is located the boss below, locks the clamp, utilizes the fixed clamp position of boss, prevents that the clamp from droing from the connecting pipe, makes the connection between degassing hose and the joint more firm.

Preferably, the boss is made of round steel. The round steel is welded on the outer wall of the connecting pipe in a surrounding manner, so that the process is simple, and the production difficulty is reduced.

Preferably, round steel is welded around the bottom end of the annular gland. The round steel is welded at the bottom end of the annular gland in a surrounding mode, so that the annular gland can be effectively prevented from deforming, the edges and corners of the bottom end of the annular gland can be prevented from being scratched, and the attractiveness of a product is improved.

Preferably, the outer edge of the annular gland is provided with a chamfer. The annular gland outer fringe is provided with the chamfer, prevents that the workman from being by the edges and corners fish tail of annular gland at the dismouting in-process.

Preferably, the clamp is an American-type hose clamp. The American-type hose clamp is adopted and disassembled by a screwdriver, so that the hose clamp is simple to operate, has long service life and can bear larger pressure requirements.

Compared with the prior art, the utility model has the following advantages:

the connection through a tool is not needed, and the butterfly nut carried by the ventilation hatch cover is connected and fixed with the pressing plate of the connector, so that the operation is simple; the degassing hose can not drop in the degassing operation, and the leakproofness between degassing hose and the ventilation hatch cover improves, has solved the gas leakage problem between degassing hose and the ventilation hatch cover, has stronger commonality, can use on various boats and ships repeatedly, and the facilitate promotion is used.
