According to the dustproof cover, the arc spraying opening used for arc spraying and heat dissipation is formed in the first baffle, meanwhile, the second baffle used for shielding the arc spraying opening is additionally arranged on the inner side of the first baffle, and it is guaranteed that the dustproof cover has good heat dissipation and dustproof effects.

This utility model relates to the technical field of pull-out kitchen tool storage boxes. This pull-out kitchen tool storage box includes two dividers and a plastic tool box. The dividers have hooks at the bottom and can be fixed in place via adjustment holes at the bottom of the plastic tool box to prevent movement. The dividers have a slope for easy placement, retrieval, and drainage of tools. The plastic tool box consists of a knife holder area, a cutlery area, a small tool area, and a placement area. Each section of the plastic tool box has drainage holes at the bottom. The plastic tool box can be used with pull-out basket products using the four-sided placement area. The storage function of this utility model, composed of a knife holder area, a cutlery area, and a small tool area, is rationally allocated and has high utilization, meeting the storage needs of a large number of small tools in the kitchen. The sloped dividers facilitate easy retrieval and drainage. The pull-out kitchen tool storage box can be used with pull-out basket products using the four-sided placement area, improving space utilization and providing dust protection.

This utility model belongs to the field of display cabinets, specifically a rotating dustproof display cabinet. Addressing the problem that most existing display cabinets use a fixed structure, limiting their placement to a single location and resulting in limited viewing angles and mediocre display effects, this invention proposes the following solution: a polygonal base and a polygonal display frame rotatably mounted on top of the base. Each face of the polygonal display frame has a door frame rotatably mounted on it. Multiple placement plates are used to hold exhibits, and these plates are fixedly mounted inside the polygonal display frame. During use, the rotation of the polygonal display frame allows for omnidirectional display of multiple exhibits, enabling any exhibit to be moved to the main display area, thus improving the display effect. Furthermore, the internal fixing mechanism provides limiting and fixing for the polygonal display frame and door frames. This display cabinet is dustproof, easy to operate, and offers excellent display results.

The utility model relates to an electric power metering screen, which belongs to the technical field of electric power metering screens, and comprises a main body box body, the inner side of the main body box body is provided with a body assembly used for installing electric power equipment, and the main body box body is internally provided with a heat dissipation assembly used for heat dissipation. The heat dissipation assembly comprises a mounting hole formed in the bottom of the main body box body, a mounting piece which is connected to the inner bottom wall of the main body box body through screws and is located on the outer side of the top of the mounting hole, two fans which penetrate through and are fixed to the top of the mounting piece, and two heat dissipation holes formed in the side face of the main body box body; the dust boards are detachably installed on the inner sides of the heat dissipation holes, the front holes are formed in the front face of the main box body, and the inclined baffles are fixed to the front face of the main box body. According to the electric power metering screen, a good heat dissipation effect can be achieved, meanwhile, a certain dustproof effect is achieved, dust is prevented from entering the electric power metering screen, and the heat dissipation capacity and the practical performance of the electric power metering screen are greatly improved.

The utility model discloses a three-phase asynchronous motor capable of improving assembly stability, which comprises a shell, a rear end cover and a mounting sleeve, and is characterized in that a base is fixed below the shell; a first limiting mechanism is arranged at the right end of the rear end cover and comprises limiting blocks and a mounting rod, the limiting blocks are distributed on the inner side of the rear end cover at equal angles, and the longitudinal section of each limiting block is of an L-shaped structure; and the mounting sleeve is integrally arranged on the right side of the shell, a second limiting mechanism is arranged in the mounting sleeve and comprises limiting frames, supporting springs and positioning blocks, and the limiting frames are distributed in the mounting sleeve at equal angles. The left end clamping groove of the shell is connected with a rear end cover, and a ventilation net is fixed in the left side of the rear end cover. According to the three-phase asynchronous motor capable of improving the assembly stability, parts can be conveniently limited and then installed, the assembly stability is improved, the three-phase asynchronous motor has a dustproof effect, dust can be prevented from entering the motor, and normal operation of the internal parts is ensured.
