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 a ship, and belongs to the field of fastening devices for ships. According to the fastening device for emergency maintenance of the ship, after a nail is shot by a nail gun, a nail body of the shot nail can be embedded into a to-be-fastened piece under the action of kinetic energy, and the kinetic energy is converted into heat energy, so that the temperature of the shot nail body is increased, softening of hot melt adhesive for inner sealing of capillary cracks is further caused, and the sealing effect is reduced; after the to-be-fastened piece makes contact with a lubricating ring, due to the fact that the diameter of the nail body is increased, lubricating oil loaded in a rotating groove is squeezed out along the capillary cracks and smeared on the surface of the nail body, the resistance encountered when the nail body is embedded into the to-be-fastened piece is reduced, the shot nail can be embedded into the to-be-fastened piece only through small initial kinetic energy to be fixed, the kinetic energy needed by the shot nail can be greatly reduced while the fastening strength of the shot nail is guaranteed, and serious casualties caused by accidental use of the nail gun in a relatively bumpy environment in the ship are not likely to happen.

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...
