The utility model relates to the technical field of keys, in particular to a silica gel key, which comprises a conductive block and a metal sheet, a pressing cavity is arranged at the bottom of the silica gel key, an elastic cavity is arranged in the pressing cavity, the conductive block is mounted in the elastic cavity, and the metal sheet is detachably mounted on the lower end face of the silica gel key. One end face of the metal piece abuts against the lower end face of the elastic supporting ring, a second connecting hole is formed in the metal piece and communicated with the elastic cavity, the metal piece is provided with an elastic piece, one end of the elastic piece abuts against the upper end face of the elastic cavity, and the other end of the elastic piece is installed on the upper end face of the metal piece. The pressing hand feeling of the silica gel key can be kept by arranging the elastic block in the elastic cavity, after the silica gel key is used for a long time, the elastic piece can support the elastic cavity, meanwhile, the metal sheet is arranged in the pressing cavity, the pressing hand feeling can be further improved, the silica gel key is clearer and more sensitive, and more comfortable pressing feeling is brought to a user.

This invention relates to the field of precision drive and positioning technology, and discloses a three-dimensional macro-micro composite positioning stage, which includes a stage body, an X-axis motion component, a Y-axis motion component, a Z-axis motion component, and a mobile terminal platform connected to the X-axis motion component, Y-axis motion component, and Z-axis motion component respectively. The X-axis motion component includes an X-axis macro-drive and an X-axis micro-drive; the Y-axis motion component includes a Y-axis macro-drive and a Y-axis micro-drive; the Z-axis motion component includes a Z-axis macro-drive and a Z-axis micro-drive, used to jointly drive the mobile terminal platform to linear motion along the X-axis, Y-axis, and Z-axis. This invention balances large stroke and high precision, achieving three-dimensional positioning with millimeter-level stroke and nanometer-level precision. The X-axis, Y-axis, and Z-axis micro-drives use piezoelectric ceramic direct drive, resulting in high positioning accuracy and fast response speed. The overall structure of this invention is reasonable and compact, and its operation is reliable.

The utility model relates to the technical field of decoration engineering, in particular to an intelligent dust removal device for decoration engineering. The technical problems that according to an existing dust removal device, when a handheld dust collector is used for collecting dust, part of wall dust is not adsorbed and falls off, dust on the wall is raised, suspended dust enters air, respiratory tract problems or anaphylaxis is caused, the health of workers is reduced, the height of the handheld dust collector is limited, part of height dead corners of the wall are not easy to clean, and the dust collection effect is poor are solved. And the whole cleaning effect is not good. According to the technical scheme, the intelligent dust removal device for the decoration engineering comprises a driving box, an adjusting dust removal assembly, a sweeping assembly and a spraying assembly; the rotating rod is sleeved with the steel wire to be connected with the sectional rod to adjust the height of the dust collection plate, the height of the dust collection plate is easily adjusted, the dust collection plate is suitable for dust collection work of decoration engineering walls with different heights, the dust collection plate is intelligently controlled to conduct back-and-forth dust collection treatment along the walls, and the requirements of different cleaning requirements and working scenes are met.

The utility model discloses cloth ironing equipment for garment processing, which belongs to the technical field of cloth ironing and comprises a support table, an ironing box is mounted at the top of the support table, an ironing module is arranged in the ironing box, two support plates are connected to the top of the support table, the tops of the two support plates are connected with the same winding device, and the winding device is connected with the ironing module. The winding device comprises a first fixing plate, a bottom block, two connecting rods and a winding drum; according to the device, the rotating disc is rotated to drive the short threaded rod to rotate, so that the short threaded rod moves through the nut, the short threaded rod drives the moving plate to move, the moving plate drives the connecting block to move, the connecting block drives the connecting rod on one side to move through the limiting plate, and the connecting rod slides out of the moving groove; and therefore, the connecting rod loses the fixing effect on the winding drum, the winding drum is taken out, and the situation that the cloth disassembling efficiency is affected by excessive operation when the winding drum is disassembled is avoided.

The present invention discloses a high-tech thermal insulation cotton and a preparation method thereof, which relate to the technical field of thermal insulation filling materials. The high-tech thermal insulation cotton comprises an intermediate layer and two surface layers, wherein the intermediate layer is arranged between the two surface layers; the intermediate layer and the two surface layers are both paved with at least one fiber web; in terms of mass percentage, the material of each of the fiber webs comprises 80%-90% of curled hollow fibers and 10%-20% of low-melting-point fibers; the gram weight range of each of the fiber webs is 5g / m 2 ‑10g / m 2 The fineness of the curled hollow fiber is in the range of 0.5D-4.0D. The present invention adopts a laminated composite structure design, uses the curled hollow fiber as the main material, and uses the low melting point fiber as the auxiliary material, which can effectively ensure the shape retention, resilience, fluffiness and warmth retention of the scientific and technological thermal insulation cotton, thereby significantly improving the application value of the scientific and technological thermal insulation cotton.
