Description

Technical Field

[0001] The invention relates to the technical field of sealing devices, in particular to a rubber plug for a deck outboard pipe. Background Art

[0002] The rubber plug for deck outboard pipe is used for deck outboard pipes of various types of ships. When the deck outboard pipe is not in use, it can be sealed with this rubber plug to prevent oil and other pollutants from leaking into the water. If the outboard pipe on the deck of a ship is not properly sealed, oil and other pollutants will leak into the water. The traditional way of blocking and sealing with wooden boards, rags, etc. leads to poor sealing. Although some measures have been taken, there will still be leakage causing water pollution.

[0003] In view of the above problems, we provide a deck outboard pipe rubber plug to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a rubber plug for a deck row outboard tube to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A rubber plug for an outboard pipe of a deck drain comprises a rubber plug for being inserted into a drain outlet of a drain pipe, the drain outlet of the drain pipe being arranged on the outer side of the deck surface, a cavity area being arranged in the middle of the rubber plug, an adjusting portion for squeezing the cavity area from both inside and outside being passed through the axis of the rubber plug, the adjusting end of the adjusting portion being arranged at the outer end of the rubber plug, a deformable section being arranged at a section of the rubber plug located inside the drain pipe, the deformable section being located at the outer circle of the cavity area, and when the adjusting portion squeezes the cavity area, the deformable section bulges outward and presses against the inner wall of the drain pipe.

[0006] As a further solution of the present invention: the rubber plug is axially arranged as a through hole, and the upper and lower openings of the through hole are respectively fixed with a top limit plate and a bottom limit plate, and the top limit plate and the bottom limit plate enclose the middle part of the through hole to form the cavity area.

[0007] As a further solution of the present invention: the adjustment part includes a handle, a screw and a nut, the handle is rotated by the top limit plate to pass through the cavity area, the inner end of the handle is fixed to the screw, the screw slides through the bottom limit plate, and the inner end surface of the bottom limit plate is provided with a nut for cooperating with the screw.

[0008] As a further solution of the present invention: reinforcement layers are provided on both inner and outer end surfaces of the rubber stopper.

[0009] As a further solution of the present invention: the inner side surface of the bottom limiting plate is provided with a limiting groove for limiting the rotation of the nut.

[0010] As a further solution of the present invention: a trumpet-shaped stress-bearing ring is fixed to the edge of the inner end surface of the rubber plug.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention selects a rubber plug of suitable caliber to seal in the pipeline, and rotates the handle to rotate the screw to tighten the fixed plate at the end, so that the middle rubber plug expands and fits tightly against the inner wall of the pipeline, replacing the traditional sealing method. It is also more convenient to install and disassemble, and can be operated by one person.

[0012] 2. The stress ring provided in the present invention can further increase the friction of the rubber plug, which will cause water to be squeezed from the deformable section, causing possible overflow problems. Moreover, after the stress ring is expanded, a more closed stress surface is formed. The water pressure will continue to press the inner end surface of the rubber plug, so that the deformable section will continue to be compressed and compressed more tightly, thereby achieving a better sealing effect.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1

[0020] See also Figure 1-Figure 2In an embodiment of the present invention, a rubber plug for a deck drain outboard pipe includes a rubber plug 3 for being inserted into a drain outlet of a drain pipe 1, the drain outlet of the drain pipe 1 is arranged on the outer side of a deck surface 2, a cavity area is arranged in the middle of the rubber plug 3, an adjusting portion for squeezing the cavity area from both inside and outside is pierced through the axis of the rubber plug 3, the adjusting end of the adjusting portion is arranged at the outer end of the rubber plug 3, a section of the rubber plug 3 located inside the drain pipe 1 is provided with a deformable section, the deformable section is located on the outer circle of the cavity area, when the adjusting portion squeezes the cavity area, the deformable section bulges outward and presses against the inner wall of the drain pipe 1.

[0021] The rubber stopper 3 is axially arranged as a through hole, and the upper and lower openings of the through hole are respectively fixed with a top limit plate 4 and a bottom limit plate 7, and the top limit plate 4 and the bottom limit plate 7 enclose the middle of the through hole to form the cavity area.

[0022] The adjusting part includes a handle 5, a screw 6 and a nut 8. The handle 5 is rotated by the top limit plate 4 to penetrate into the cavity area. The inner end of the handle 5 fixes the screw 6. The screw 6 slides through the bottom limit plate 7. The inner end surface of the bottom limit plate 7 is provided with a nut 8 for matching and connecting with the screw 6. During operation, the handle 5 is used to drive the screw 6 to rotate, and the screw 6 cooperates with the nut 8 to change the length of the bottom limit plate 7, and the top limit plate 4 and the bottom limit plate 7 form support for both sides of the rubber plug 3. The upper and lower sides of the cavity area are exerted with force, and the deformable section of the rubber plug 3 bulges outward, and the bulging part is tightly against the inner wall of the drain pipe 1 to form a firm compression seal.

[0023] Among them, the inner and outer end surfaces of the rubber stopper 3 are both provided with reinforcement layers 9. When working, the reinforcement layers 9 can effectively bear the pressure applied by the adjustment part without deformation, ensuring that the extrusion force is transmitted to the deformable section, thereby ensuring the normal deformation of the deformable section, rather than the inner and outer ends of the rubber stopper 3 causing the problem of inward collapse due to force.

[0024] Wherein, the inner side surface of the bottom limiting plate 7 is provided with a limiting groove for limiting the rotation of the nut 8; During operation, the provided limiting groove can ensure that the nut 8 remains stationary, thereby preventing the screw rod 6 and the nut 8 from rotating simultaneously.

[0025] Example 2

[0026] See also Figure 3-Figure 4 , which is different from the embodiment 1 in that: a trumpet-shaped force ring 10 is fixed to the inner end edge of the rubber plug 3; During operation, when the water pressure in the drain pipe 1 is too high, the water pressure will cause the force ring 10 to expand outward, thereby pressing against the inner wall of the drain pipe 1, thereby further increasing the friction between the rubber plug 3 and the inner wall of the drain pipe 1, and preventing water from being squeezed from the deformable section to cause possible overflow problems. Moreover, after the force ring 10 is expanded, a more closed force surface is formed, and the water pressure will continue to press the inner end surface of the rubber plug 3, so that the deformable section will continue to be compressed and compressed more tightly, thereby achieving a better sealing effect.

[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Although this specification is described in accordance with the implementation modes, not every implementation mode includes only one technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
