The invention discloses a waterproof floor socket, which comprises a socket body, a panel and a cover plate. The panel is fixedly arranged at the upper end of the socket body. The cover plate and the panel are respectively and fittingly provided with an upper wiring groove and a lower wiring groove at the wire outlet end of a plug. The top surface of the panel is provided with a circle of waterproof groove formed closer to the outer edge of the top surface of the panel. A first soft rubber strip and a second soft rubber strip are arranged in the waterproof groove respectively. A waterproof rib is arranged on the bottom surface of the cover plate. When the cover plate is covered, the first soft rubber strip is pressed by the waterproof rib. Meanwhile, the position of the second soft rubber strip corresponds to the position of the lower wiring groove in the panel, so that the inner end of the lower wiring groove in the panel is plugged by the second soft rubber strip. A third soft rubber strip is arranged on the bottom surface of the cover plate. The inner end of the upper wiring groove in the panel is plugged by the third soft rubber strip. When the cover plate is covered, the second soft rubber strip and the third soft rubber strip are tightly pressed by each other. The panel is provided with a chipper for limiting the opening and closing of the cover plate. By adopting the above technical scheme, no matter the floor socket is in the use state or not, the waterproof effect is effectively realized. The waterproof floor socket is simple in structure, and convenient to use.

The invention discloses a waterproof sealing structure for port connection, comprising a casing (1) having a socket terminal hole (12); a socket (2) installed on the casing (1) having a socket terminal (22), the socket terminal (22) passing through the socket terminal hole (12) on the casing (1), further comprising a sealing piece (3); middle of the sealing piece (3) is definitely formed with a first opening hole (36) passing through the socket terminal (22); and two end faces of the sealing piece (3) are continuous sealing faces; one end face is joined with the casing; the other end face is joined with the relative sealing contact surface (511) on the plug body (51) of the plug (5). The invention further discloses a notebook PC. The invention can realizes the waterproof sealing when using the port; the invention has simple structure, little size and can easily realize thin design without changing the port structure of the existed apparatus.

The invention discloses a watertight method and structure of a marine elevator. The elevator includes a car device, a car door device and a landing door device. The car door device is arranged on the car device, and the landing door device is arranged on the well side wall of the ship corresponding to the deck of the ship. Above, it includes a watertight door device, which can be selectively moved between the car door device and the landing door device, and the watertight door device is watertightly connected with the side wall of the hoistway to seal the landing door device in a watertight manner. By arranging the watertight door device on the side wall of the shaft inside the elevator shaft, and making the watertight door device between the car door device and the landing door device, when the watertight sealing operation of the landing door device is required, the watertight door can be controlled to move to Between the car door device and the landing door device, the watertight connection between the watertight door device and the side wall of the hoistway is realized to realize the watertight sealing of the landing door device.

The invention relates to an outsourcing waterproofing construction method for penetrating metal roof panel components. The frame body protrudes from the upper end surface of the substrate, thereby providing a certain support for the second waterproof coiled material through the frame body, which is beneficial to reduce the damage of the second waterproof coiled material. The hollow is beneficial to reduce the tensile stress received by the second waterproof membrane. After laying the first waterproof roll material and the second waterproof roll material, the external waterproofing is carried out by applying a waterproof paint layer, so as to ensure the waterproof effect of the holes through multi-layer waterproofing. The whole structure cooperates with each other, and the waterproof cover plate is connected with the original roof panel to increase the overall rigidity of the waterproof structure, reduce the relative displacement between the flexible waterproof material and the metal roof panel, and protect the flexible waterproof material; at the same time, it is better to use flexible waterproof materials Excellent flexibility, to avoid the waterproof part being damaged by the vibration and displacement caused by the live load.
