The invention belongs to the field of automobile door interior trim panels, particularly relates to an automobile plastic automobile door interior trim panel with noise reduction and sealing functions, and provides the automobile plastic automobile door interior trim panel with the noise reduction and sealing functions aiming at the problem that the noise reduction and sealing effects are limited in the prior art, the automobile plastic automobile door interior trim panel with the noise reduction and sealing functions comprises an interior trim panel, and the interior trim panel is formed in a three-layer injection mode. The inner side face of the interior trim panel is sequentially provided with a hollow glass layer and a protective layer, and the interior trim panel, the hollow glass layer and the protective layer are bonded and fixed through sound insulation colloid. The interior trim panel adopts the synergistic noise reduction design that a three-layer composite structure is matched with the hollow glass layer and the multi-material honeycomb noise reduction filter element; compared with a traditional single noise reduction structure, the multi-frequency-band noise isolation and absorption system can effectively improve the noise isolation amount and remarkably improve quietness in a vehicle.

The invention relates to the technical field of fire-fighting reels, and discloses an automatic winding fire-fighting reel which comprises a base support and a center pipe. A reel pipe is wound on the reel; the control mechanism is used for controlling winding of the reel pipe and drainage during winding; one end of the central pipe is connected with a valve pipe, and a connector is arranged on the valve pipe. According to the automatic winding fire-fighting reel, automatic electric winding of the reel can be achieved through the arranged servo motor, meanwhile, the servo motor is disconnected with the reel, the overall water pipe pulling-out resistance is reduced, the water pipe is pulled out more smoothly, and therefore the winding efficiency of the water pipe is improved. A circulating inflating structure is formed by utilizing the rotating power of the water pipe in the winding process, the wound water pipe is continuously inflated, then accumulated water in the water pipe is subjected to air pressure type inflating and self-discharging, it is guaranteed that the accumulated water in the water pipe can be effectively discharged, therefore, the protection performance of the water pipe is improved, and the material hardening condition caused by long-time water accumulation is avoided.

The utility model relates to the related technical field of floor tile splicing, in particular to a greening floor tile connecting structure which comprises a floor tile body and a connecting frame, a planting groove is formed in the center of the top end of the floor tile body, a greening part is arranged in the planting groove, and a widened base part is arranged on the periphery of the bottom of the floor tile body. A first inserting groove is formed in the top end of the widened base part, a plurality of water conveying holes are formed in the side portion of the floor tile body, the bottom end of the connecting frame is symmetrically connected with two first inserting plate parts matched with the first inserting groove, a net plate is placed in the connecting frame, and a plurality of through holes in butt joint with the water conveying holes are formed in the two sides of the bottom of the connecting frame; the bottom ends of the floor tile bodies are provided with water storage plates, the bottoms of the planting grooves are provided with water discharging ports communicated with the water storage plates, the connecting structure connects and fixes the two adjacent floor tile bodies through the connecting frames, meanwhile, water is conveniently guided into the planting grooves and drained out of the planting grooves, and the using effect is better.
