The utility model relates to the technical field of hairdressing equipment, in particular to a rotary adjustable hair curling rod which comprises a shell, a hair curling assembly, a rotary shifting piece and an upper limiting block. The gear set of the rotary base is meshed with the driven gear, and the second gear teeth of the rotary shifting piece are meshed with the gear set, so that accurate rotation control over the curling iron is achieved, the curling angle and the curling direction can be adjusted more flexibly and stably, the curling effect and the user experience are improved, and the practicability is high. The heating piece is guided through the first moving guide rail and the second moving guide rail, the stability and accuracy of the heating piece in the hair curling process are guaranteed, the problems that a traditional hair curling rod is uneven in heating and unsmooth in hair curling are solved, the hair curling quality is effectively improved, and the upper limiting block and the top cover improve the structural stability of the hair curling rod and improve the hair curling efficiency. And in addition, the use safety is improved, the heating piece is prevented from accidentally falling off or shifting, and safer and more reliable use experience is provided for a user.

This invention discloses a compact high-temperature, high-pressure transmission XAFS in-situ cell, comprising a cell body and a cover that are sealed together. A light-transmitting window assembly is installed on the cell body, allowing X-rays to pass through and irradiate the sample to be tested, which is installed inside the cell body. The cell body and cover are also connected to and equipped with components such as a ball valve, a gas connection, a temperature probe, test electrodes, and a heating element. The heating element is used to regulate the sample temperature, and a water-cooling structure located in the side wall of the cell body is used to regulate the cell body temperature. This invention integrates a ball valve control structure on the same cell body. When the ball valve is closed, a high-pressure atmosphere can be established and maintained inside the cell body to achieve high-temperature, high-pressure transmission XAFS experiments; when the ball valve remains open, the inside of the cell body is in a normal-pressure gas flow state, achieving high-temperature, normal-pressure transmission XAFS experiments. One device can meet the testing requirements of two different operating conditions, significantly reducing the user's equipment investment costs.

The utility model relates to molten iron transfer equipment technical field especially relates to a molten iron transfer equipment with protection function, the utility model provides such a molten iron transfer equipment with protection function, including support frame, transport pipe, collection frame and electronic valve, a plurality of support frames have transport pipe jointly fixed connection, the upper end of transport pipe is connected and has the collection frame, is provided with electronic valve on collection frame, still include the connecting plate, temperature insulation cotton and screw, the outer side of transport pipe is detachably provided with multiple connecting plates, the two connecting plates of mutual contact jointly screw a plurality of screws, and the inner wall of connecting plate is provided with temperature insulation cotton, and temperature insulation cotton is closely contacted with transport pipe, in the transportation process, temperature insulation cotton effectively reduces the heat loss of molten iron through transport pipe wall outward, keeps the molten iron temperature, prevents its premature solidification, simultaneously, temperature insulation cotton insulates the high temperature of transport pipe surface, protects the operator from scalding, and reduces the heat radiation to the surrounding environment.

The application relates to a deviation correction detection device and an oven equipment. The device comprises a detection unit arranged on at least one side of a substrate running path, which is used for detecting the deviation of the substrate edge. The detection unit comprises a photoelectric detection assembly and a reflection assembly, and a detection light path is formed between the photoelectric detection assembly and the reflection assembly. An execution unit comprises a position adjustment mechanism, which is in contact with the substrate and is used for driving the lateral movement of the substrate. A control unit is used for controlling the lateral movement of the position adjustment mechanism to correct the deviation of the substrate according to the deviation signal detected by the detection unit. The reflection assembly and the position adjustment mechanism are arranged in a first temperature region, the photoelectric detection assembly and the control unit are arranged in a second temperature region, and the temperature of the first temperature region is higher than that of the second temperature region. The scheme provided by the application can improve the deviation correction control precision of the substrate in a high-temperature environment, thereby improving the tension uniformity of the substrate in the coating and baking process.
