Wherein: cover plate 1, frame 2, support 3, bolt 4, spring 5, bowl-shaped piece 6, limit stop device 7, connecting rivet A8, edge A9, edge B10, connecting piece 11, rubber pad 12 and connecting rivet B13
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: cover plate 1, frame 2, support 3, bolt 4, spring 5, bowl 6, limit stop 7, connecting rivet A8, edge A9, edge B10, connecting piece 11, rubber pad 12 and connecting rivet B13. The floor opening cover is formed by connecting and combining a cover plate 1, a frame 2, a supporting piece 3, a bolt 4, a spring 5, a bowl-shaped piece 6 and a limiting and stopping device 7 into a whole; the floor opening frame is connected into a whole by an edge strip A9, an edge strip B10 and a connecting piece 11, a rubber pad 12 is adhered on the supporting opening cover surfaces of an edge strip A9 and an edge strip B10 of the opening frame, and the flange edges at the periphery of the floor opening frame are fixedly arranged below a floor beam and a panel.
The typical use case is that floor flap is when closed floor opening, and the flap is placed in floor opening mouthful frame, inserts through the retractable bolt 4 that sets up at its horizontal both sides and fixes in the pinhole of floor opening mouthful frame strake B10, and bolt 4 utilizes the spring 5 of its installation to realize flexible function, stirs bowl-shaped piece 6 and drives bolt 4 and withdraw from in mouthful frame strake B10's pinhole when opening the flap by bare-handed, takes out the flap from mouthful frame, realizes opening.
When the cover is opened and used as a protective cover plate, the length and the width of the cover are reversed and then placed above the floor opening, and a gap formed by the difference between the length of the floor opening and the width of the cover keeps the air inside and outside the cabin to circulate; and the limit stop device 7 is positioned in the recess of the edge strip A9 of the opening frame, the front edge and the rear edge of the opening frame of the floor limit the movement of the direction of the heading of the opening cover, the concave limit areas on the supporting surfaces of the front edge strip A9 and the rear edge strip A9 of the opening frame limit the movement of the opening cover in the transverse direction, the opening cover is not limited from the bottom to the top, and the opening cover can move upwards and outwards from the inside and the outside of the floor cabin.
The floor covering plate is of a high-strength aluminum alloy frame structure, the upper surface of the frame is connected and covered with an aluminum alloy panel and sealed, the upper panel is a square checkered plate to play a role in skid resistance, a support piece is arranged in the frame and connected with the upper panel and the frame, and the covering plate of the covering plate is riveted. The opening frame of the floor adopts an invagination support type high-strength aluminum alloy structure, so that the upper surface of the cover plate of the opening cover is flush with the surface of the floor; the periphery of the opening frame is provided with sectional type supporting edge strips, and the edge strip sections are in butt joint connection through connecting pieces so as to meet the supporting requirements on the opening cover, personnel and goods.
