Description

Plug device for water falling opening

Technical Field

The utility model relates to a plug device technical field that rises, concretely relates to mouth of falling into water rises plug device.

Background

Along with the rapid development of the ship industry, the ship industry develops rapidly, so that various ship equipment is presented, but most of the ship equipment is complex to operate and install and low in utilization rate, and installation of other outfitting parts is hindered.

The problems exist in the existing water falling port expansion plug device, the existing common expansion plug device often interferes with a handrail on a ship, so that the common expansion plug device is not easy to assemble and disassemble, the appearance is influenced after the common expansion plug device is installed, the common expansion plug device is difficult to install, the installation is not stable, and the deck cannot be reliably sealed in a water injection state when falling into water.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a mouth that falls into water stopper device that rises solves one or more among the above-mentioned prior art problem.

According to the utility model discloses an aspect provides a drain hole stopper device that rises, including sealing plug, upper cover plate, handle and screw rod, the sealing plug upper end is connected with the upper cover plate, and the upper cover plate upper end is provided with the screw rod, has cup jointed the handle on the screw rod, and the upper cover plate lid connects on the deck, and the sealing plug both sides are laminated with the pipe in the water mutually.

Wherein, upper cover plate, handle and screw rod are detachable device, convenient assembly and dismantlement, labour saving and time saving.

In some embodiments: oil-dredging layers are arranged on the surfaces of the sealing plug and the upper cover plate. Therefore, the oil stain is difficult to stick on the surface, and the cleaning is convenient.

In some embodiments: an elastic layer is arranged inside the sealing plug. Therefore, the sealing performance of the plug expanding device is greatly improved.

In some embodiments: the elastic layer comprises an elastic net and an elastic ball, the elastic ball is positioned in the elastic net, and the mesh of the elastic net is smaller than the diameter of the elastic ball. Thus, the elastic net is used for preventing the elastic ball from leaking.

In some embodiments: the elastic ball is a hollow ball. Therefore, the material is saved, the elasticity of the elastic ball is increased, and the sealing plug receives outward elasticity to be sealed more.

In some embodiments: the main component of the sealing plug is nitrile rubber. Thus, the use of nitrile rubber can provide the sealing plug with good water resistance, tear resistance, abrasion resistance, flexibility, fluid heat dissipation, and oil resistance.

In some embodiments: the upper cover plate, the handle and the screw rod are all made of stainless steel with high corrosion resistance. Therefore, the corrosion resistance of the plug expansion device is greatly improved, and the service life of the plug expansion device is prolonged.

Has the advantages that:

the utility model relates to a mouth of falling into water stopper device that rises has good water resistance, tear resistance, wearability, pliability, fluid thermal diffusivity, corrosion resistance and oil resistance, and not only simple structure can dismantle at any time, still has very big leakproofness.

1. a sealing plug; 11. an elastic layer; 111. an elastic net; 112. a resilient ball; 2. an upper cover plate; 3. a handle; 4. a screw; 5. a deck; 6. a downpipe.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, the device for expanding plug of the water falling port comprises a sealing plug 1, an upper cover plate 2, a handle 3 and a screw rod 4, wherein the upper end of the sealing plug 1 is connected with the upper cover plate 2, the screw rod 4 is arranged at the upper end of the upper cover plate 2, the handle 3 is sleeved on the screw rod 4, the upper cover plate 2 is covered on a deck 5, and two sides of the sealing plug 1 are attached to a water falling pipe 6.

In some embodiments, oil-dispersing layers are distributed on the outer surfaces of the sealing plug 1 and the upper cover plate 2, so that oil stains are difficult to stick on the oil-dispersing layers, and the oil stains are convenient to clean.

In some embodiments, the main component of the sealing plug 1 is nitrile rubber, which provides good water resistance, tear resistance, abrasion resistance, flexibility, fluid heat dissipation, and oil resistance.

In some embodiments, as shown in fig. 2, an elastic layer 11 is disposed inside the sealing plug 1, and the elastic layer applies an outward tension to the side surface of the sealing plug by the elastic force of the elastic layer, so as to greatly improve the sealing performance of the plug expansion device, where the elastic layer 11 includes an elastic net 111 and elastic balls 112, the elastic balls 112 are uniformly distributed inside the elastic net 111, and the mesh of the elastic net 111 is smaller than the diameter of the elastic balls 112, so as to prevent the elastic balls 112 from leaking out of the elastic net 111.

In some embodiments, as shown in fig. 3, the resilient ball 112 is a hollow ball, thereby not only saving material, but also increasing the resilience of the resilient ball, so that the sealing plug receives an outward resilience and is more sealed.

In some embodiments, the upper cover plate 2, the handle 3 and the screw rod 4 are made of stainless steel with high corrosion resistance, so that the corrosion resistance of the plug expansion device is greatly improved, and the service life of the plug expansion device is prolonged.

To sum up, the utility model discloses mainly control the extension of sealing plug 1 through manual turning handle 3 to drive the inside elasticity layer 11 of sealing plug 1, when 3 rotations of handle are motionless, fixed seal the mouth of falling into water promptly.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, similar modifications and improvements can be made without departing from the inventive concept of the present invention, and these are also considered to be within the protection of the present invention.
