The application relates to the technical field of automobile parts, in particular to a test tray and an ADAS test device. The test tray comprises a positioning module and a probe module. The positioning module comprises a supporting part and a floating mechanism, the supporting part is installed on a base through the floating mechanism, a supporting surface of the supporting part is provided with a plurality of positioning pins, and at least two of the positioning pins are different in shape. The probe module is detachably installed on the base. The supporting part provides the supporting surface for stably placing a material piece thereon; the supporting surface is provided with the plurality of positioning pins, one of the two positioning pins which are different in shape can be used for primary positioning, and the other one can be used for secondary positioning, so that the tolerance of a hole position of the material piece in a specific direction can be absorbed, the positioning precision can be ensured, and the tolerance problem of hole spacing of the material piece can be ingeniously solved. The probe module is designed to be detachably installed on the base, the maintenance and replacement of the probe are efficiently and flexibly realized, the structural stability of the test tray is avoided from being affected, and the test tray does not need to be recalibrated after replacement.

This invention relates to a standard device for extending the liquid circuit for easy extravehicular operation by astronauts, comprising an extension adapter and an extension housing. The extension adapter is the passive end, installed on the spacecraft cabin and launched with the spacecraft. The extension housing is the active end, installed by the astronaut after exiting the spacecraft and attached to the extension adapter. The extension adapter and the extension housing are connected mechanically, electrically, and through liquid circuits. These interfaces are all standard interfaces, and the connection method is independent of the type of liquid circuit equipment installed inside the extension housing, such as pump assemblies, valve assemblies, and working fluid replenishment assemblies. The standard device for extending the liquid circuit of this invention features standardized interface design, adaptability for astronauts operating while wearing extravehicular spacesuits, no need for auxiliary tools, simple operation, and short operation time, and can meet the requirements for pressurized, leak-free operation of the extravehicular liquid circuit.

This utility model discloses an electric furnace for the thermal regeneration of molten ceramic sand, comprising a furnace body. Inside the furnace body are a first heating component, a second heating component, and a third heating component. A door is hinged to one side of the furnace body. A slide rail is fixedly connected to the inner wall of the furnace body, and the slide rail is symmetrically distributed about the bisector of the furnace body. The third heating component and the first heating component have the same structure as the second heating component. The first, second, and third heating components are located on three sides of the inner wall of the furnace body, respectively. A material rack is fixedly connected between the third heating component and the first heating component. The second heating component includes a mounting box slidably connected to the inner wall of the furnace body. A heating rod is threadedly connected to the inner wall of the mounting box, and the mounting box is movably connected to the inner wall of the furnace body. This device allows for the maintenance and replacement of individual heating rods, thereby reducing the maintenance cost of the heating rods.
