Problems solved by technology

[0004] Ships are mostly made of steel structure materials. When encountering extreme weather such as wind and waves, once the ship is damaged, maintenance work needs to be carried out in time. Maintenance personnel can use nails and nail guns to perform fast fastening and repair work. However, inside the ship In a relatively bumpy environment, the use of high-energy nails and nail guns can easily cause casualties in the event of an accident, while the use of low-kinetic nails and nail guns is prone to insufficient fastening strength and failure to stop damage in time

Embodiment 1

[0040] see figure 1 and Figure 7-10 , a fastening device for emergency maintenance of ships, comprising a nail body 1, the nail body 1 includes a nail body and a nail cap fixedly connected to each other, the diameter of the nail body away from the top cap gradually decreases, the nail body is covered A gear ring 2 and a lubricating ring 3 are provided. The lubricating ring 3 is located on the side of the gear ring 2 away from the top cap. The lubricating ring 3 includes an elastic rubber ring 301. A filling cavity 303 is dug in the elastic rubber ring 301. The filling cavity 303 is filled with Lubricating oil, the inner wall of the elastic rubber ring 301 has a plurality of capillary cracks 305, and the plurality of capillary cracks 305 run through the elastic rubber ring 301 to connect the filling cavity 303 with the outside world, and the capillary cracks 305 are closed by hot melt adhesive. It is fixedly connected with an elastic net 306 matching itself.

Abstract

The invention discloses a fastening device for emergency maintenance of ships, which belongs to the field of fastening devices for ships, and relates to a fastening device for emergency maintenance of ships. Under the action of the above kinetic energy, the body will be embedded into the fastener to be fastened, and the kinetic energy will be converted into heat energy, so that the temperature of the nailing body will rise, which will cause the hot melt adhesive used for sealing the capillary cracks to soften, and the sealing effect will be reduced. After the lubricating ring is in contact, due to the increase in the diameter of the nail body, the lubricating oil loaded in the rotating groove will be squeezed out along the capillary cracks, and coated on the surface of the nail body, reducing the resistance encountered by the nail body embedded in the fastener, so that the nail It can be embedded in the fastener to be fixed with only a small initial kinetic energy, which can greatly reduce the kinetic energy required for the nail while ensuring the fastening strength of the nail, and is not easy to be damaged in the relatively turbulent environment of the ship. The accidental use of the nail gun caused serious casualties.

Description

technical field [0001] The invention relates to the field of fastening devices for ships, more specifically, to a fastening device for emergency maintenance of ships. Background technique [0002] Nail shooting refers to the use of gunpowder gas or compressed air generated by firing empty shells as power to drive nails into the building. It usually consists of a nail plus a gear ring or a plastic positioning collar. The role of the gear ring and the plastic positioning collar It is to fix the nail body in the barrel of the nail gun to avoid sideways when firing. The function of the nail is to drive the nail into the matrix such as concrete or steel plate to fasten the connection. [0003] Because the nails are driven by gas or compressed air, they usually have relatively large kinetic energy, so they can easily penetrate steel plates and concrete panels and play a fastening role. Therefore, they are often used in home improvement and other processing fields, including home i...
