In order to improve waterproofing between a crimping part and an insulating coating of a coated electric wire in an electric wire connection structure, this electric wire connection structure (1) is provided with: a coated electric wire (100) in which a core wire part (101) is coated by an insulating coating (102); and a terminal (200) which has a crimping part (230) that connects to the core wire part (101) and the insulating coating (102). The crimping part (230) has a closed cross-sectional shape which surrounds the coated electric wire (100). The crimping part (230) has protruding parts (234) at sections of the crimping part (230) corresponding to boundary sections of a pair of male and female dies (300) when crimped. At least one pressing part (235) is provided to the protruding parts (234).

The invention discloses a waterproof and heat-preservation lunch bag processing material, and relates to the technical field of waterproof and heat-insulation material processing, the waterproof and heat-preservation lunch bag processing material comprises a waterproof inner layer, a heat preservation intermediate layer and a decorative outer layer, wherein the waterproof inner layer is processedby using a PVC film, the decorative outer layer is made of a waterproof fabric, and the heat preservation intermediate layer is made of the following raw materials by weight: 30-40 parts of asbestos wool, 10-20 parts of sepiolite fiber powder, 20-30 parts of a gelling agent, 5 to 10 parts of magnesium aluminum silicate, 1 to 5 parts of microcrystalline wax, 1 to 5 parts of cationic polyacrylamide,and 1 to 5 parts of ultrafine tetrafluoroethylene powder. A lunch bag prepared from the waterproof and heat-preservation lunch bag processing material has the triple characteristics of heat preservation, inner layer waterproofing and outer layer waterproofing, and meets people's demand for use of lunch bags in present; and the prepared lunch bag is light in weight, convenient in cleaning and longin service life.

The invention relates to a harbor shore power supply boat control cabinet system. The control cabinet system is characterized by including a cabinet body, a first shore power cabinet interface, and a second shore power cabinet interface, the casing of the cabinet body is in a double-layer waterproofing panel structure, a rubber waterproofing flat pad and a rubber waterproofing U-shaped pad are arranged in the double-layer waterproofing panel, a protective cover is arranged on the first shore power cabinet interface, and a protective cover is also provided on the cabinet body port of the second shore power cabinet interface. Waterproofing washers are arranged at the connection parts of the binding post and the cabinet body port with the cabinet casing, and the cabinet body port has the waterproofing protection on the cable, so that the wet offshore air and seawater can be greatly prevented from entering into the cabinet body to erode the internal structure, and the service life of the shore power supply boat control cabinet is improved.

The invention provides a prefabricated building sealing waterproof intelligent teaching practical training device which is used for prefabricated building sealing waterproof teaching practical training. Cognitive learning of a splicing seam structure, a wall sealing principle and structure waterproofing and material waterproofing intelligent teaching practical training under an informatization condition are satisfied. A real training environment for sealing is created, a waterproof construction outer layer of the wallboard is wrapped with a stainless steel plate, four walls are spliced to form a rectangle and slide to be opened and closed under the driving of an electric guide rail along the diagonals of the rectangle by taking intersection points of the diagonals as starting and ending points, and the splicing seams of the walls are fully displayed; practical trainees can carry out wall body splicing seam construction, sealing principle learning and gluing seam sealing technology repeated practical operation training. An informatization technology is applied to construct a three-dimensional virtual scene of a sealed waterproof construction environment, the three-dimensional virtual scene is presented on a large screen to synchronously demonstrate the sealed waterproof construction operation process of the fabricated building in real time, and the practical training process of practical training students is objectively evaluated and a record report is generated.
