Abstract
The utility model discloses an easily open type watertight hatch board belongs to boats and ships hatch board technical field. The utility model discloses an including embedded installing in the lid frame of watertight hatch, articulating the apron on the lid frame through the hinge, the below of apron and the inner circle fixed mounting of lid frame have the rubber seal who matches, and the four corners of apron is provided with rotatable pressure switch, the one side of keeping away from the hinge on the apron is provided with the pull ring, and this watertight hatch lid is still including being used for driving the rotatory zip fastener mechanism of apron. The utility model discloses an add zip mechanism on the lid frame, through the handle of rotating zip mechanism, can stimulate the pull ring for the apron is opened round the hinge, has avoided being difficult to the direct condition of opening because the inside and outside pressure differential of watertight hatch board is great and the apron that arouses.
Description
Technical Field
The utility model relates to a boats and ships hatch board technical field, concretely relates to type watertight hatch board easily opens.
Background
A watertight compartment is a compartment surrounded by a bulkhead and a deck that remain watertight under a given water pressure. The watertight compartment should minimize the number of openings, all of which have adequate watertight fittings and are effectively sealed. The ship is provided with a certain number of watertight cabins, and the watertight cabins have the main functions of preventing water from overflowing to other cabins after one cabin or a plurality of cabins of the ship are damaged and enter water, ensuring certain floating state and stability and ensuring certain sinking resistance of the ship.
The existing ship body hatch cover has large internal and external pressure difference due to self sealing, and can be difficult to directly open in emergency.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to an easily open type watertight hatch board.
The technical scheme of the utility model is that: the utility model provides an easily open type watertight hatch board, includes embedded installing in the lid frame of watertight hatch, articulates the apron on the lid frame through the hinge, and the below of apron and the inner circle fixed mounting of lid frame have the rubber seal who matches, and the four corners of apron is provided with rotatable pressure switch, and the one side of keeping away from the hinge on the apron is provided with the pull ring, and this watertight hatch board is still including being used for the rotatory zip fastener mechanism of drive apron.
According to a further technical scheme, the zipper mechanism comprises a fixed support fixedly mounted on the cover frame, a rotating shaft fixedly mounted through a bearing seat is arranged on the fixed support, a roller is fixedly mounted on the rotating shaft, and the roller is connected with the pull ring through a rope.
According to a further technical scheme, a handle which is coaxial with the rotating shaft is arranged on the fixing support.
According to the further technical scheme, the number of the handles is 2, and the handles are respectively arranged at two ends of the rotating shaft.
The utility model has the advantages that:
the utility model has the advantages of simple structure, through add the zip fastener mechanism on the apron frame, through the handle that rotates zip fastener mechanism, can stimulate the pull ring for the apron is opened round the hinge, has avoided being difficult to the direct condition of opening because the inside and outside pressure differential of watertight hatch board is great and the apron that arouses.
Drawings
FIG. 1 is a schematic structural view of the present invention,
figure 2 is a left side view of the structure schematic diagram of the present invention,
the device comprises a cover frame 1, a cover frame 2, a cover plate 3, a hinge 4, a rubber sealing ring 5, a compression switch 6, a pull ring 7, a fixing support 8, a rotating shaft 9, a roller 10, a rope 11 and a handle.
Detailed Description
The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.
As shown in fig. 1-2, the utility model relates to an easily open type watertight hatch board, including embedded installing in the lid frame 1 of watertight hatch board, articulating apron 2 on lid frame 1 through hinge 3, the below of apron 2 and the inner circle fixed mounting of lid frame 1 have the rubber seal 4 that matches, the four corners of apron 2 is provided with rotatable pressure switch 5, the one side of keeping away from hinge 3 on the apron 2 is provided with pull ring 6, this watertight hatch board is still including being used for driving the rotatory zip 10 mechanism of apron 2.
The zipper 10 mechanism comprises a fixed support 7 fixedly mounted on the cover frame 1, a rotating shaft 8 fixedly mounted through a bearing seat is arranged on the fixed support 7, a roller 9 is fixedly mounted on the rotating shaft 8, and the roller 9 is connected with the pull ring 6 through a rope 10.
The fixed bracket 7 is provided with a handle 11 which is coaxial with the rotating shaft 8. The number of the handles 11 is 2, and the handles are respectively arranged at two ends of the rotating shaft 8.
Through turning handle 11, pivot 8 can be through rope 10 pulling pull ring 6 for apron 2 opens round hinge 3, has avoided the circumstances that the apron is difficult to directly open that arouses because the inside and outside pressure differential of watertight hatch board is great.
