The invention provides a sand box with a pressing device. The sand box comprises an upper sand box body and a lower sand box body, and the upper sand box body and the lower sand box body are fixed through the pressing device. The pressing device comprises an arch-shaped connecting rod, a connecting plate and a rotating screw, the connecting plate is fixed to one side of the lower sand box body, the lower end of the arch-shaped connecting rod is fixed to the connecting plate, the upper end of the arch-shaped connecting rod is located at the upper portion of the upper sand box body, and the rotating screw is rotationally connected to the upper end of the arch-shaped connecting rod. A vertical through hole is formed in the upper end of the arch-shaped connecting rod, an internal thread is formed in the through hole, and an external thread matched with the internal thread is arranged on the rotating screw.

The invention discloses a fixing bracket for glass transportation, mainly relates to the field of construction equipment transportation. The fixing bracket for glass transportation comprises a main bracket body, a guide rail mechanism, a glass supporting mechanism, a limiting assembly and a buffering piece. The glass supporting mechanism achieves L-shaped extension adjustment by the bidirectionalguide rail mechanism, and achieves fixing and limiting by the limiting assembly; and the buffering piece achieves rigid shock absorption of glass. The fixing bracket has the beneficial effects of being capable of adapting to different conditions on site according to the glass with different sizes and characteristics to fix and transport the glass, significantly lowering transportation losses and improving resource utilization rate.

The invention discloses a rice steaming cabinet. The rice steaming cabinet comprises a cabinet body and a cabinet door. A hollow steam chamber is arranged inside the cabinet body. A sink is arranged at the bottom wall of the steam chamber, and an electric heating pipe is arranged inside the sink; a pair of rotating shafts are rotationally and horizontally connected to the interior of the cabinet body, and the rotating shafts are distributed at the upper and lower ends of the cabinet body, and a servo motor driving the rotating shafts to rotate is arranged at the outer wall of the cabinet body;the two ends of the rotating shafts are each provided with a gear, the two gears located at the same ends of the rotating shafts is wound by a chain, a plurality of uniformly-distributed supporting rods are horizontally arranged between the pair of chains, a hanging bracket is rotationally connected to each of the two ends of the supporting rods, and trays are arranged between the pair of hangingbrackets. The rice steaming cabinet has the advantages that by arranging the trays capable of rotating inside the steam chamber, each tray can make contact with high heat at the bottom of the steam chamber, and therefore each tray is heated more uniformly, and it is ensured that rice inside each tray can be cooked at the same time. Meanwhile, the rice cooking time is shortened, energy dissipationis saved, and the effect of saving energy is achieved.

The invention discloses application of a welding preheating device, and belongs to the technical field of welding preheating. According to the application of the welding preheating device, the welding preheating device comprises a body, wherein the body comprises a positioning mechanism, a preheating mechanism and an adjustment mechanism, the positioning mechanism is arranged below the weld joint side, the preheating mechanism is arranged on the bottom end face close to a weld joint, and the adjustment mechanism is connected between the positioning mechanism and the preheating mechanism and used for adjusting the pressing degree of the preheating mechanism and the bottom end face of the weld joint; and the application of the welding preheating device comprises the step of assembling, the step of mounting and adjustment, and the step of dismounting. According to the application of the welding preheating device, the preheating mechanism is positioned in the position close to a preheated object through the positioning mechanism, the adjustment mechanism is used for adjusting the preheating mechanism and the pressing degree of the preheated object and the preheating mechanism, and thus the technical problem that the preheating time or temperature cannot be controlled easily is effectively solved.
