Abstract

The utility model discloses a single-side open and close wind and water proof hatch adjustable seal locking device, the structure of which is that a press board 7 is fixedly arranged on the cover board 11 of the hatch, a sealing ring 10 is fixedly arranged inside the cover board 11, and an ear board 1 is fixedly arranged on the corresponding position of the profile of the hatch boarding 13 and the press board 7. A pin axis 8 is inserted into the round hole of the ear board 1. An eyelet bolt 5 is used to cover the pin axis 8. A thumb nut 6 is screwed into the eyelet bolt 5. A square groove 12 is arranged in the inner side of the ear board 1, while an adjusting shim 3 is arranged at the bottom of the square groove 12. A support block 2 is arranged on the adjusting shim 3. A tightening screw 4 is inserted into the orientating screw on the square groove to allocate the support block 2. The eyelet bolt is arranged into the breach of the press board. The sealing ring of the hatch can carry out insulation when the thumb nut is tightened. The height of the support block can be adjusted to confirm the compression value by decreasing or increasing the amount of the shims of the sealing ring, thereby getting a reasonable and reliable seal to prolong the service life of the rubber sealing ring.

Description

Single face opens and closes the adjustable sealing-locking device of weather tightness hatch cover

One, technical field

This use is novel, and what relate to is small-sized hatch cover sealing-locking device on a kind of ship, and a kind of specifically single face opens and closes the adjustable sealing-locking device of weather tightness hatch cover.

Two, background technology

At present, the boats and ships of International Association of Classification Societies's code requirement manufacturing after 2004, the small-sized hatch cover of exposed section in its bow 0.25 captain's scope needs the hatch cover that adopts cover plate and latching device to strengthen.Both the locking place back-up block that requires to be provided with on otic placode contacted with side edge thereof, and applied certain predetermincd tension by jam nut.Because the back-up block seam is on otic placode, limited cover plate to bottom offset, make that the gap when loosening and lock is a definite value between cover plate and the back-up block, after using a period of time, because variation of temperature and rubber is aging, the hatch cover in use suffered pressure of the rubber seal between cover plate and the hatch changes to some extent, and its variation can not change with operation conditions change, cause the rubber seal can not positiver sealing, cause wind and rain to enter in the cabin.

Three, summary of the invention

In order to solve the deficiencies in the prior art, the purpose of this utility model provides the reasonable failure-free single face of a kind of sealing and opens and closes the adjustable sealing-locking device of weather tightness hatch cover.

Realize that the technical scheme that the purpose of this utility model adopts is: this single face opens and closes the adjustable sealing-locking device of weather tightness hatch cover and mainly is made up of otic placode, back-up block, adjusting backing plate, holding screw, eyelet bolt, fly nut, pressing plate, bearing pin, spring cotter; Relevant position on the cover plate of hatch cover is fixed with the pressing plate of the band gap that leans out cover plate, be fixed with rubber seal on the periphery in the cover plate with the hatch coaming sealing contact, hatch coaming side and pressing plate correspondence position crosswise fixed have cooresponding two otic placodes, be inserted with bearing pin in the circular hole of otic placode by the spring cotter locking, activity is with eyelet bolt on the bearing pin, is screwed with fly nut on the eyelet bolt; Otic placode is inboard to have square groove with cover plate outer rim corresponding section, cell wall has positioning screw hole, trench bottom is placed with the adjusting pad, regulates on the pad and is placed with the cuboid back-up block that the upper surface heads on cover plate outer rim lower surface, is screwed with the holding screw with the back-up block location in the positioning screw hole on the cell wall.Eyelet bolt is placed in the gap of pressing plate, tighten fly nut, the seal ring in the hatch cover can make in the cabin and be hedged off from the outer world; Regulate the amount of compression that the back-up block height is determined seal ring by the quantity that reduces or increase pad.

The beneficial effects of the utility model are: owing to adopted the adjusting pad, the height of back-up block can be adjusted, regulate the amount of compression of rubber seal to optimum regime according to working condition by reducing or increase the quantity of regulating pad, thereby obtain reasonable failure-free sealing, prolonged the service life of rubber seal.

Fig. 1 opens and closes the assembly structure figure of the adjustable sealing-locking device of weather tightness hatch cover for the utility model single face.

Fig. 2 opens and closes the A-A sectional structure chart of the adjustable sealing-locking device Fig. 1 of weather tightness hatch cover for the utility model single face.

Five, the specific embodiment

In the accompanying drawings, for opening and closing the adjustable sealing-locking device of weather tightness hatch cover, the utility model single face mainly forms by otic placode, back-up block, adjusting backing plate, holding screw, eyelet bolt, fly nut, pressing plate, bearing pin, spring cotter; Relevant position on the cover plate 11 of hatch cover is fixed with the pressing plate 7 of the band gap that leans out cover plate, be fixed with rubber seal 10 on the periphery in the cover plate 11 with hatch coaming 13 sealing contacts, hatch coaming 13 sides and pressing plate 7 correspondence position crosswise fixed have cooresponding two otic placodes 1, be inserted with bearing pin 8 in the circular hole of otic placode 1 by spring cotter 9 lockings, activity is with eyelet bolt 5 on the bearing pin 8, is screwed with fly nut 6 on the eyelet bolt 5; Eyelet bolt 5 and fly nut 6 all adopt and meet bolt, the nut that International Association of Classification Societies (IACS) requires.Otic placode 1 inboard has square groove 12 with cover plate outer rim corresponding section, and cell wall has positioning screw hole, and trench bottom is placed with regulates pad 3, regulates the quantity and the thickness of pad and selects as required; Be placed with the cuboid back-up block 2 that the upper surface heads on cover plate 11 outer rim lower surfaces above regulating pad 3; The profile of regulating pad 3 is identical with the profile of back-up block 2, and there is detent the two sides of back-up block 2; Be screwed with the holding screw 4 that makes back-up block 2 location in the positioning screw hole on the cell wall of square groove 12.Cover plate outer rim lower surface was pressed on the back-up block when hatch cover was closed, and seal ring compresses hatch coaming, regulated the amount of compression that the back-up block height is determined seal ring by the quantity that reduces or increase pad.
