This invention discloses a steam curing device for cement-based materials, comprising a mounting frame and a cover. The cover is rotatably connected to the mounting frame, and a locking block is rotatably connected to the cover for fixing it in place. This invention achieves automatic adjustment of the curing temperature through an electrical connection between a temperature detector and the closing assembly, eliminating the need for frequent manual intervention, reducing labor costs, and preventing temperature fluctuations from adversely affecting the curing effect. It provides a stable high-temperature and high-humidity curing environment for cement-based materials, promoting material strength improvement and performance optimization, and ensuring that curing quality meets standards.

The utility model discloses a front -positioned cleaning spray gun subassembly of angle can automatic regulation relates to cleaning spray gun field, including seat convenient, the inside installation of seat convenient has the cleaning subassembly, the cleaning subassembly contains water supply pipe, the end of water supply pipe is provided with the cleaner, one side of cleaner is provided with drive assembly. The utility model hydraulic cylinder is pushed to the outside by moving plate to connecting column, and servo motor is rotated through drive link and drives first bevel gear, and first bevel gear is rotated through second bevel gear and drives rotating disc, and in the rotating disc rotating process, first drive column drives first drive plate and rotates, and first drive plate is displaced through connecting rod and drives second drive plate, so that second drive plate moves to first drive plate one side, and second drive plate drives cleaner and rotates with second drive column as center, thereby making the spray head of cleaner front end installation can change the direction of play.

The utility model relates to a fuse, and specifically relates to a melt structure and a fuse with high arc extinguishing capability. Comprising two connecting pieces used for being connected with conductive terminals of the fuse, a plurality of connecting parts and a plurality of fusing parts. The plurality of fusing parts and the plurality of connecting parts are sequentially and alternately connected to form a fuse body, and two ends of the fuse body are respectively connected with the two connecting pieces; protective plates are arranged on the upper surface and the lower surface of the fusing part; a gap is reserved between the protection plate and the fusing part, and the gap is filled with an arc extinguishing medium. According to the utility model, an unextinguished electric arc is blocked through the protection plate, the spraying direction of the electric arc is changed, and the transmission path of the electric arc between the protection plate and the fusing part is changed, so that the energy of the electric arc is continuously weakened in the transmission process, the impact strength of the electric arc on the wall of the ceramic tube of the fuse is greatly reduced, and the ceramic tube is prevented from being broken.
