Description

Technical Field

[0001] The utility model relates to the technical field of deck drain port sealing, in particular to a ship deck drain port sealing structure. Background Art

[0002] The deck is an important component of the hull. It is a planar structure located above the inner bottom plate in the ship structure. It is used to cover the space inside the ship and divide it horizontally into layers. Usually, the accumulated water on the ship deck flows into the deck drain pipe through the downspout on the deck, and then is discharged through the drain holes on the side.

[0003] For example, the solution disclosed in the prior art CN214093557U (a deck drain plug) includes a plug body and a pull rod, wherein the plug body includes a first sealing gasket, a first pressure plate and a second pressure plate, wherein the edge of the first sealing gasket is used to abut against the sealed deck drain; and the pull rod is connected to the plug body. The plug body is composed of a first sealing gasket, a first pressure plate and a second pressure plate, and a pull rod is connected to the plug body. Although this solution can effectively prevent sewage from flowing out along the outer plate of the hull and has the advantages of simple structure, easy manufacture and assembly, and convenient use, this solution still has defects. For example, during use, a lot of garbage will accumulate on the top of the first pressure plate, and the garbage will fall into the drain when the plug body is pulled out, and the pressure plate will take up more space in daily use. Therefore, we propose a ship deck drain sealing structure to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a sealing structure for a ship deck water outlet to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ship deck drain port sealing structure, comprising a screw, the bottom of the screw is fixedly connected to a lower pressure plate, the outer ring of the lower pressure plate is provided with two groups of sealing rubber rings, the outer ring of the screw is threadedly connected to an upper pressure plate, the top of the upper pressure plate is welded with a handle, the outer ring of the upper pressure plate is provided with a sealing rubber ring, and the top of the screw is welded with a connecting plate.

[0006] Preferably, a threaded hole is provided on the top of the upper pressing plate.

[0007] Preferably, a fixing hole is opened at the top of the connecting plate, the top of the connecting plate is snap-connected with a pull rod connecting block, a pull rod is welded to the top of the pull rod connecting block, a structural hole is opened in the inner cavity of the pull rod connecting block, and the inner cavity of the structural hole is movably connected with a fixing block.

[0008] Preferably, pressing holes are provided on both sides of the pull rod connecting block, the fixing blocks are arranged in two groups and are symmetrically distributed, and a reset spring is arranged between the two groups of fixing blocks.

[0009] Preferably, the return springs are arranged in three groups.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The sealing structure of the ship deck drain port is to push the lower pressure plate into the drain port, and the sealing rubber ring will seal the drain port. Then, the handle is turned to drive the upper pressure plate to rotate, so that the upper pressure plate moves longitudinally to be flush with the deck, effectively preventing garbage from accumulating on the top of the drain port in daily use, and performing secondary sealing on the drain port, thereby increasing the sealing performance of the solution.

[0012] 2. The sealing structure of the ship deck drain port pushes the fixing blocks on both sides inward so that the fixing blocks squeeze the reset springs inward, and then the fixing blocks are inserted into the bottom of the fixing holes. Then the fixing blocks are released, and the reset springs drive the fixing blocks to reset, thereby fixing the connection between the pull rod connecting plate and the fixing blocks. This solution allows the pull rod to be fixed or removed at any time, which can effectively save the use space on the deck and reduce the manufacturing cost of the solution. Multiple sealing devices only require one pull rod to be used. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Embodiment 1:

[0018] When used specifically, Figure 1 and Figure 2As shown, a sealing structure for a ship deck drain port comprises a screw 1, a lower pressure plate 2 is fixedly connected to the bottom of the screw 1, two groups of sealing rubber rings 3 are arranged on the outer ring of the lower pressure plate 2, an outer ring of the screw 3 is threadedly connected to an upper pressure plate 4, a handle 6 is welded to the top of the upper pressure plate 4, a sealing rubber ring 3 is arranged on the outer ring of the upper pressure plate 4, a connecting plate 5 is welded to the top of the screw 1, a threaded hole is opened on the top of the upper pressure plate 4, a fixing hole 11 is opened on the top of the connecting plate 5, a pull rod connecting block 7 is snap-connected to the top of the connecting plate 5, a pull rod 8 is welded to the top of the pull rod connecting block 7, a structural hole 9 is opened in the inner cavity of the pull rod connecting block 7, a fixing block 10 is movably connected to the inner cavity of the mechanism hole 9, pressing holes are opened on both sides of the pull rod connecting block 7, the fixing blocks 10 are arranged in two groups and are symmetrically distributed, a reset spring 12 is arranged between the two groups of fixing blocks 10, and the reset spring 12 is arranged in three groups.

[0019] Specifically, align the lower pressure plate 2 with the drain outlet and push it in to a suitable depth, then the sealing rubber ring 3 will seal the drain outlet, and then by rotating the handle 6, the handle 6 will drive the upper pressure plate 4 to rotate, and the threaded hole will rotate along the screw and drive the upper pressure plate 4 to move longitudinally until the upper pressure plate 4 is rotated to be flush with the top of the drain outlet. At this time, in daily use, it can effectively prevent garbage from accumulating at the drain outlet sealing, and the sealing rubber ring 3 on the upper pressure plate 4 can perform secondary sealing on the drain outlet, thereby increasing the sealing performance of the drain outlet.

[0020] Furthermore, after the sealing device is pushed into the drain outlet by pressing down the pull rod 8, the two sets of fixing blocks 10 are pushed inward, the fixing blocks 10 move inward and compress the return spring 12, and the fixing blocks 10 are removed from the fixing blocks 11. Then, the pull rod 8 can be separated from the sealing device, and vice versa, they can be quickly assembled. This solution can save space on the deck by quickly disassembling and assembling the pull rod, and multiple sealing devices can be used with only one pull rod, which saves the manufacturing cost of the solution.
