Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "provided," "connected," and the like are to be construed broadly, and the specific meanings of the above terms in the present invention can be understood in specific situations by those skilled in the art. Furthermore, the terms "upper", "lower", "left", "right", "vertical", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 to 13, the specific implementation process of the present invention is as follows:

a ceiling access panel is installed on a single-layer metal ceiling and comprises an access panel 1, a door lock 4 and a connecting part.

The access panel 1 is a single-layer metal ceiling 2 made of the same material as the ceiling 2, one side of the access panel 1 is provided with a door lock 4, and the other side is rotatably connected with the ceiling 2. In this scheme, there are two kinds of opening and shutting directions of access panel, and the specific connected mode is seen in the following example.

The single-layer metal ceiling 2 is a strip-shaped sheet structure, see fig. 13, and comprises a bottom plate 11 and side vertical plates 12 which are folded upwards at two sides of the vertical plate 11, the upper ends of the side vertical plates 12 at two sides are simultaneously bent towards the same side to form an inner folded edge 13 and an outer folded edge 14 respectively, and the outer folded edges 14 and the inner folded edges 13 of two adjacent single-layer metal ceilings 2 are buckled and fixedly connected through rivets 8. Wherein, the length of the outer folding edge 14 is larger than that of the inner folding edge 13, so that a spacing groove 21 is formed between the two single-layer metal ceilings 2.

The access panel 1 is connected side by a plurality of individual layer metal ceilings 2, and the top of two adjacent individual layer metal ceilings 2 is equipped with several font reinforcements 7, and reinforcements 7 include footing 71 and ridge board 72, footing 71 and bottom plate 11 fixed connection, and ridge board 72 is located the junction top of two individual layer metal ceilings 2. The reinforcement 7 is arranged to reinforce the connection between adjacent single-layer metal ceilings 2 without breaking when the access panel is loaded. The shape of the reinforcing member 7 herein includes, but is not limited to, a reinforcing plate, a reinforcing rib, and the like.

Specifically, a fireproof layer 3 is arranged above the bottom plate 11. The material of the fire-proof layer 3 includes but is not limited to rock wool and other fire-proof heat-insulating materials, and is used for improving the fire-proof and safety performance of the access panel.

Be equipped with lock box 5 between door lock 4 and access panel 1 for the vibrations between 4 and the access panel of buffering door lock, restriction door lock 4's rotation route prolongs its life simultaneously. And a bolt backing plate 9 is arranged on the ceiling 2 corresponding to the door lock 4 and positioned between the bolt of the door lock 4 and the ceiling 2, so that the functions of shock absorption and buffering are achieved.

The following embodiments are used to specifically describe the present invention:

example 1: referring to the attached drawing 1, the opening and closing direction of the access panel is perpendicular to the overlapping direction of the single-layer metal ceiling 2, the door lock 4 is arranged on the left side of the access panel, and the front and the back of the right side of the access panel are respectively provided with a rotating shaft 6 which is rotatably connected with the ceiling 2. When the access panel rotates around the rotating shaft 6, the access panel can be opened and closed only by controlling the door lock 4.

Example 2: see figure 7, the direction of opening and shutting of access panel is on a parallel with the overlap joint direction of individual

layer metal ceiling

2, and 2 left side riser 12 of ceiling on access panel right side and access panel rightmost end outer hem 14 stagger this moment for the access panel can be opened smoothly, sets up lock 4 at the access panel front end, and the opposite side sets up row hinge 61 and is connected with ceiling 2.

Example 3: based on embodiment 1 and embodiment 2, when the space of the ceiling board 2 is limited, the size of the access panel needs to be simplified, and in this case, a single-piece single-layer metal ceiling board 2 is used for the access panel on the basis of embodiment 1 and embodiment 2, and the difference is that the simplified access panel reinforcement 7 does not need to be in a zigzag shape, and the reinforcement 7 is replaced or not provided according to the structure of the single-layer metal ceiling board 2.

The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
