The invention discloses a dustproof net for a case. The dustproof net comprises a first net body and a second net body, wherein the first net body and the second net body are connected in a sliding way to adjust overlap area between the first net body and the second net body, and a positioning piece is arranged between the first net body and the second net body and is used for positioning the first net body and the second net body. By sliding matching of the first net body and the second net body and positioning of the positioning piece, the size of the dustproof net can be flexibly adjusted by simple operation, the dustproof net can be applied to different types of cases after the size is adjusted, a dustproof effect can be achieved after the dustproof net is arranged in a case panel, andthe applicability can be improved. Moreover, the invention also discloses the cast comprising the dustproof net, and the applicability of the dustproof net is relatively good.

The invention provides a cement slurry cleaning apparatus for a building template with a function of integrating shoveling grinding with dust fall by water mist, relating to the field of buildings. With the apparatus, the building template can be reused because cement slurries remaining on the building template are easily cleaned. The cement slurry cleaning apparatus for the building template withthe function of integrating shoveling grinding with dust fall by water mist comprises a control inner housing. The outside of the control inner housing is equipped with a protection housing matchingwith the control inner housing in a sleeved manner. The top of the inner wall of the protection housing is bonded with the top of the control inner housing through a micro protection mechanism. The top of the inner wall of the control inner housing is bonded to an inner top housing box, below which a grinding and shoveling mechanism is arranged. A driving motor controls a double-surface shovel edge to rotate in order to shovel cement slurries. Rotary grinding protrusions contact the cement slurries on the template. Accordingly, cement slurries with strong bonding force can be gradually crushedfrom the template so that the cleaning purpose is fulfilled. The cleaning quality of the cement slurries on the template is effectively ensured.

The invention discloses a novel power generator. The novel power generator comprises a rack, wherein an electric generator and an air purifier are mounted at the bottom of the inner cavity of the rack; an inverter and the air purifier are mounted on the two sides of the electric generator respectively; the bottom of the air purifier is connected with a waste gas exhaust pipe; a partition plate isfurther mounted inside the rack and is fixedly connected with one end of the inverter; a support is arranged on the side, away from the electric generator, of the air purifier; a control panel is mounted above the support, and the other end of the control panel is connected with the partition plate; and a fuel tank and a silencer are mounted above the partition plate. The novel electric generatoris provided with the silencer, so that when the novel electric generator works, noise is lowered, and residents are prevented from being disturbed; as a solar crystal plate is arranged, when a power outage occurs or the novel electric generator is used outdoors during daytime, solar energy can be used for generating electricity, energy is saved, the novel power generator is easy and convenient touse, simple in structure and convenient to use, and energy is saved.

The invention relates to the technical field of woodworking machinery, in particular to a single-spindle woodworking milling machine with a high-speed spindle. The milling machine comprises a machine frame, a workbench, a milling cutter device, a milling cutter lifting device and a motor, wherein the workbench and the machine frame are fixedly connected; a control device is arranged on the machine frame; the milling cutter device comprises a spindle, a milling cutter, a cutter assembling nut, a flat hole sleeve and a cutter pressing screw; and the milling cutter lifting device is composed of a lifting screw, a sliding plate, a sliding plate base, a lifting hand wheel, a lifting nut, a locking device, a worm gear, a worm, a bearing and a bearing base. The milling machine is characterized in that the shaft of the motor extends and is connected with the spindle into a whole; the lower end of the cutter assembling nut is fixedly connected with an upper end cover of the motor; the motor and the sliding plate are fixedly connected; the milling cutter is directly driven by the motor; and parts, such as a motor plate, a transmission belt, a motor wheel, a spindle wheel and the like, are saved, thus the manufacturing cost of a machine tool is effectively lowered, the integral performance of the machine tool is steady, the power consumption of the motor is reduced, and the milling machine is steady to operate.

The invention relates to a lock cylinder dust cover. The lock cylinder dust cover is characterized in that the lock cylinder dust cover comprises a shell (1) which is used for being fixed to a lock cylinder (4) and provided with a containing cavity; penetrating holes (2) are formed in the front wall and the rear wall of the shell (1); two oppositely arranged baffle blocks (3) which can slide left and right are mounted in the containing cavity of the shell (1); and the baffle blocks (3) are restrained in the containing cavity and can rotate with the axes of the penetrating holes (2) as the center. In the normal state, the two baffle blocks get close under the action of an elastic part and cover the penetrating holes, so that the dust prevention function on the lock cylinder is achieved. When a key is inserted into the space between the two baffle blocks, the elastic part is pressed, the two baffle blocks are separated; and due to the fact that the baffle blocks can rotate relative to the shell, after the key pushes away the baffle blocks and penetrates through the penetrating holes to be inserted into the lock cylinder, the key is rotated, the baffle blocks can also rotate along with the key, the unlocking operation through key rotation is easier, and the design is more humanized.

The invention relates to a coat hanger which comprises a base, a main rod, a plurality of hanging rods and a dustproof cover. The lower end of the main rod is connected with the base, the upper end ofthe main rod is connected with the dustproof cover, the hanging rods are arranged on the main rod, a sliding rail is arranged on the annular edge of the lower end of the dustproof cover, a pluralityof sliding blocks are arranged on the sliding rail, a dustproof curtain is further arranged, and the upper end of the dustproof curtain is connected with the sliding block. According to the coat hanger, dust prevention can be effectively conducted on hung clothes, and dismounting is convenient.
