The utility model discloses a high stability shielding wall, including wallboard, the wallboard includes double -deck main shielding layer, and is equipped with aluminium alloy honeycomb core layer between adjacent main shielding layer and main shielding layer mutually far away one side, be equipped with water guide subassembly in aluminium alloy honeycomb core layer, the aluminium alloy honeycomb core layer outer wall located wallboard one side is equipped with dampproof insulating layer, the waterproof layer is covered to wallboard other parts, the waterproof layer is insulating waterproof layer, and the adjacent wallboard is connected with the assembly block of electric conduction, the assembly block all is equipped with conducting adhesive around, in the utility model, through setting waterproof layer, main shielding layer, dampproof insulating layer and aluminium alloy honeycomb core layer, on one hand, utilize waterproof layer and dampproof insulating layer, restrain main shielding layer and aluminium alloy honeycomb core layer produce oxidation, on the other hand, prevent the shielding effect from being influenced because of somewhere main shielding layer and aluminium alloy honeycomb core layer failure, improve the working stability of wallboard.

This utility model discloses a novel low-cost, compact transmission cable, comprising an outer sheath layer, inside which is a cotton paper layer, which is a hollow, thin-walled structure. Several parallel conductors are disposed within the cotton paper layer. Furthermore, a first shielding layer, a second shielding layer, a third shielding layer, and a fourth shielding layer are disposed within the cotton paper layer. Each of the first, second, third, and fourth shielding layers has an aluminum foil layer, and each of these layers contains a conductor. This novel low-cost, compact transmission cable employs a shielding method of adding a ground wire and aluminum foil to its data transmission unit. This achieves cost savings while maintaining a certain shielding effect, making it more economical and achieving structural optimization. It effectively achieves shielding while reducing the space occupied.

This utility model provides a shielding door structure with a downward-pressing lifting blade, comprising a shielding chamber, an entrance to which is equipped with two door frames, and a shielding door between the two door frames. Each of the two door frames has two outer blades, and the shielding door has an inner blade on each of its left and right sides. A fixed gap exists between the apexes of two adjacent outer blades, allowing one of the inner blades to be tightly inserted to achieve shielding, and they can be combined to form a blade group. A connecting rod is installed inside the shielding door, and a guide rail seat is installed inside the bottom of the shielding door. A lifting blade is installed at the bottom of the shielding door, and the connecting rod can drive the lifting blade to move downwards along the guide rail seat. Two beryllium copper springs are installed at the bottom of the lifting blade, and a bladeless threshold seat is installed below the lifting blade. The two beryllium copper springs can engage with the bladeless threshold seat to achieve electromagnetic wave isolation.

The utility model discloses a convection assembly for preventing microwave leakage and cooking equipment, the convection assembly comprises an inner plate, a fan and a motor main body, the inner plate is configured to be a part of a cooking liner; the fan is arranged on one side of the inner plate and located in the cooking inner container. The motor body is arranged on the other side of the inner plate and located outside the cooking inner container. The motor further comprises a motor shaft arranged on the motor body, a through hole is formed in the inner plate, and the motor shaft penetrates through the through hole and is connected with the fan. The motor shaft is made of a non-metal material. Therefore, the metal motor shaft penetrating through the through hole is replaced by the non-metal shaft, and the non-metal shaft is non-conductive and cannot form an antenna effect to lead out the microwaves, so that the microwaves can be prevented from leaking at the through hole to the greatest extent, the influence on the body health of a user is avoided, and the product performance is better and safer.
