Floor maintenance cover

Abstract

The invention provides a floor maintenance cover comprising a cover plate body and T-shaped sealing plates arranged at the edges of the cover plate body. The floor maintenance cover is characterized in that the whole cover plate body is square, each of the four corners is provided with a nut hole used for being fixedly connected with a car body, and the cover plate body is provided with a sound-insulation heat-insulation material layer; and each T-shaped sealing plate is fixed on the cover plate body and is clamped between the cover plate body and a maintenance cover rabbet frame. The floor maintenance cover is provided with three kinds of sealing structures, and is better in dust prevention, heat insulation and noise reduction performances; the floor maintenance cover for passenger cars is not affected by the thickness of the floor in cars, and can be widely applied to the car field; the floor maintenance cover for passenger cars has two layers of supporting structures, and has enough bearing strength; the floor maintenance cover for passenger cars is simple in processing, moulding and installation processes, and production benefits can be increased; and the welding process of the maintenance cover rabbet frames is saved.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to a floor maintenance cover. Background technique [0002] The existing maintenance cover is made of bamboo plywood, simple maintenance cover aluminum profile, surface covering (floor leather), galvanized iron box, heat insulation and noise reduction cotton, door sealing strip, processing locking device and screw standard parts . The aluminum profile used is simple, the flange edge is too small, and the support strength is insufficient. People standing on the inspection cover will cause the inspection cover to sink, which is safe and reliable and the interior decoration is smooth; the processing precision of the galvanized steel box is high and Surface treatment and edge trimming and corner removal processes are required, and the welding requirements for the vertical technical parameters of the inspection port seam frame are high. In addition, the floor, frame and floor covering parts ha...

AI Technical Summary

Problems solved by technology

The aluminum profile used is simple, the flange edge is too small, and the support strength is insufficient. People standing on the inspection cover will cause the inspection cover to sink, which is safe and reliable and the interior decoration is smooth; the processing precision of the galvanized steel box is high and Surface treatment and edge trimming and corner removal processes are required, and the welding requirements for the vertical technical parameters of the inspection port seam frame are high. In addition, the floor, frame and floor covering parts have different interlayer tolerances, and the sealant strip is too high. Coarse, the turning of the inspection cover cannot be smooth and excessive, and a good sealing effect cannot be achieved. The processing technology of the inspection cover reinforcement cap in the locking device is complicated and the processing cost is high. When fixing, it is necessary to drill holes first, then tap, and then install bolts and tighten them, etc. shortcoming

as attached figure 1 As shown, the existing inspection cover only has a single-layer sealing structure, and there is no decoration on the edge of the floor inspection opening, which affects the appearance
