The utility model discloses a lid of hidden bolt structure, including lid subassembly and the movable top cover of being located on lid subassembly open, be equipped with the suction nozzle on lid subassembly, the one end of top cover is equipped with the groove body, is equipped with the movable paddle on the groove body, and the one end rotation is connected in the groove body, and the other end is buckled with lid subassembly, and the top cover is unlocked through manual rotation paddle, one side or both sides of groove body is equipped with the connection component and passes into the paddle, and the paddle is installed in the groove body through the connection component, and the connection component hides in the paddle, and the connection component is completely hidden, does not expose, and beautiful, firm and reliable, has reduced the risk that the shaft comes out, loosens because of the size cooperation difference, has greatly promoted product use convenience and the degree of appearance, avoided the abrasion that the lid falls to the shaft caused, therefore will not appear the situation that the shaft abrasion leads to the unlocking resistance feeling even damage.

This invention discloses a magnetically coupled, high-pressure resistant rotary switch, belonging to the technical field of material level detection equipment. Specifically, it comprises a housing cover, a housing, a connecting thread, a drive shaft, a magnet assembly, bearings, a dustproof oil seal, an output shaft, a purge hole, and a wiring inlet. The housing cover is sealed to the top of the housing, forming a sealed, pressure-resistant inner cavity. The drive shaft is vertically mounted inside the housing cavity, and multiple sets of bearings are fixedly fitted around its outer circumference, supporting the drive shaft. The connecting thread is fixedly connected to the bottom of the housing. This invention, by employing a non-contact magnetic coupling transmission structure, eliminates the through-type dynamic sealing structure of traditional rotary switches, fundamentally solving the problem of media leakage under high-pressure conditions. The overall structure is rationally designed, easy to install and maintain, and adaptable to the material level detection needs of various industrial scenarios, possessing good practicality and promotional value.

This utility model relates to a shock-absorbing lifting and moving base for a wire saw cutting device. It includes a lifting and moving base sleeved on the column of the wire saw cutting device. The inner side of the lifting and moving base is provided with several rolling wheels, which abut against the outer wall of the column. The lifting and moving base can move up and down on the column via the rolling wheels. The wheel body of each rolling wheel is covered with a shock-absorbing rubber sleeve. This utility model's lifting and moving base, through the rolling wheels' rolling abutment against the column and the shock-absorbing rubber sleeve on the rolling wheels, reduces the high-frequency vibration during stone cutting, thereby improving the durability of the equipment and the quality of stone cutting.

This invention relates to the field of insulation technology for DC gas-insulated metal-enclosed switchgear, and discloses a self-dispersing charge basin insulator and a self-dispersing method, comprising a central insert, an insulating component, a metal flange ring, and several permanent magnet vibration damping cover assemblies; the central insert is embedded within the insulating component; the metal flange ring surrounds the outer periphery of the insulating component; several annular grooves are formed circumferentially on the metal flange ring; the several permanent magnet vibration damping cover assemblies are correspondingly embedded in the several annular grooves; the permanent magnet vibration damping cover assemblies are used to form a magnetic field parallel to the surface of the insulating component, so as to deflect the charges moving towards the surface of the insulating component through the Lorentz force, thereby reducing charge accumulation. This invention solves the problem that traditional passive protection cannot dynamically suppress charge accumulation, while having a high degree of overall structural integration, without increasing the size of the equipment, and can be adapted to the use scenarios of compactly arranged power stations and converter stations.

The utility model discloses a ball valve reliable in sealing, which comprises a pipe body and a valve body arranged on the pipe body, a valve core assembly is arranged in the valve body, a water passing groove is arranged in the valve core assembly, the water passing groove is communicated with the pipe body, a valve cover assembly is arranged on the valve body, the valve cover assembly comprises a clamping column, the valve core assembly comprises an inserting groove, and the inserting groove is communicated with the clamping column. The clamping column is inserted into the inserting groove, the valve deck assembly drives the valve element assembly to rotate so as to control connection and disconnection of the water passing groove and the pipe body, a supporting ring is arranged between the valve body and the valve deck assembly, and the valve deck assembly is installed on the valve body through the supporting ring. A clamping type structure is adopted to replace a traditional welding mode, the problem of poor sealing possibly caused in the welding process is avoided, and the reliability of the valve is improved.
