Description
Technical Field
[0001] The utility model belongs to the technical field of containers, and specifically relates to a threshold structure and a heat-insulating container. Background Art
[0002] The drainage and insulation performance of insulated containers are important indicators for measuring such containers. The door end of an insulated container is usually equipped with a threshold, and the structure of the threshold is directly related to the waterproof and thermal insulation performance of the insulated container. The threshold of an insulated container generally includes an outer threshold, a threshold PVC that acts as an insulation, a threshold aluminum connector, and a threshold non-metallic pad. The structure of a conventional insulated container is to use an aluminum profile threshold with a flat upper surface to connect with the threshold PVC and the outer threshold, and then weld it to the aluminum profile floor during container assembly. Sometimes, it is necessary to install a guide support at the threshold to facilitate forklifts to enter and exit the insulated container to load and unload goods. If the guide support is welded directly on the existing threshold aluminum profile, two additional welds are required. First, the amount of welding is increased, which reduces production efficiency; second, the increase in welding makes it easy to deform here. In addition, for the inverted T floor according to the special track, the threshold aluminum profile is connected to the aluminum profile floor by lap welding. At this time, a blocking plate is required at the end of the aluminum profile floor, and two upper and lower welds will be added.
[0003] Therefore, developing a threshold structure and an insulated container that can combine the function of a guide support to facilitate forklifts and other equipment to enter and exit the insulated container to load and unload goods without adding more welds, saving welding materials, and avoiding the reduction in structural strength of the threshold structure due to welding quality problems, as well as a decrease in waterproof and sealing performance, is a technical problem that needs to be solved urgently.
