This invention discloses an automatic dust collection and charging base for vacuum cleaners with a display screen. The display screen allows for real-time monitoring of the device's operation, enhancing visibility and facilitating timely component inspection and adjustment. This ensures efficient and stable operation and ease of use. The charging structure features a charging rack with a clamp and conical guide groove, improving positioning stability during charging. Designed linkages and micro-switches in the charging components prevent accidental contact with conductive plates, enhancing safety. The dust collection structure includes a bottom positioning structure with upper and lower positioning rings that engage and lock together, and an embedded exhaust filter with a pull rod, improving ease of assembly and disassembly. Compared to common dust collection and charging bases, this design achieves efficient dust collection, safe charging, and convenient assembly and maintenance.

The utility model discloses a magnesium alloy prevents displacement support structure, including the telescopic unit of the radial telescopic of support opening and the support connecting rod between connecting in telescopic unit, telescopic unit possesses several mutually far away telescopic point when radial telescopic, interval selects part telescopic point as support function component mounting point, and the connecting position of support connecting rod and telescopic unit is on the telescopic point of support function component mounting point adjacent connection, the utility model discloses a function component is set up in telescopic unit, and function component includes support support arm etc, and the deformation of the region where function component is located and other areas of telescopic unit is controlled by the support connecting rod on the both sides of function component, thereby making the region where function component is located can with the process of support opening automatically to the outer surface of support contour convex, realizes the function such as the anti -displacement support or development of support.

The application discloses a tunnel air pipe winding device, which comprises a supporting seat, a rotating roller fixed on the supporting seat, end plates and exhaust valves fixed on both ends of the rotating roller, a pneumatic device comprising a fixed shaft and a spiral guide plate, the fixed shaft being rotatably connected with the end plates and the supporting seat, the spiral guide plate being fixed on the fixed shaft and abutting against the inner wall of the rotating roller, the end of the fixed shaft being in a hollow tubular structure and provided with a through hole, the first locking structure being arranged between the end plate and the supporting seat, the second locking structure being arranged between the fixed shaft and the supporting seat, and the third locking structure being arranged between the end plate and the fixed shaft, and a connecting pipe connected with the fixed shaft and a high-pressure air pipe. The device can drive the rotating roller to rotate by using the compressed air provided by the high-pressure air pipe, so as to realize the winding of the air pipe, reduce the manpower required for dragging the air pipe and improve the dragging efficiency of the air pipe.
