In the upper edge, the lower edge, the upper frame opening and the lower frame opening in the embodiment, the vertical direction is the thickness direction of the movable frame 2, when the movable frame 2 is closed, the projection is performed along the vertical direction, and the projection surface of the movable frame 2 is located in the projection surface of the fixed frame 1.

It is understood that the first and

second stopper portions

211 and 221 may have other structures than those described above, and the present invention is not limited thereto as long as the first and second stopper portions can stop the decorative plate in the thickness direction of the movable frame 2 and leak out of the surface of the decorative plate to improve the aesthetic appearance of the access door.

Referring to fig. 3 and 4, the upper frame 21 has no peripheral wall corresponding to the second side 4 of the movable frame 2 to form the above-mentioned notch, and the other positions around the upper frame 21 are all provided with side walls, which are defined as first side walls 212, and the first side walls 212 can limit the position of the decorative plate in the horizontal direction, so as to prevent the decorative plate from falling out from other directions after being installed into the movable frame 2 from the notch.

Referring to fig. 5 and 6, in the present embodiment, the lower frame 22 is provided with a second sidewall 222, and at least a portion of the first sidewall 212 and the second sidewall 222 can be overlapped and fixed to form a sidewall of the movable frame 2. Specifically, the first side wall 212 and the second side wall 222 are provided with a plurality of corresponding screw holes 23 at the overlapping position, and the two can be fixed by fasteners passing through the corresponding screw holes 23. The fastening member may be a screw, a bolt, or the like, or may be another structure, and the upper frame 21 and the lower frame 22 may be fixed by other methods, which is not limited in the present invention, as long as the upper frame 21 and the lower frame 22 can be detachably fixed.

The fixed frame 1 in this embodiment includes the tip lateral wall that is located first side 3, second side 4 both ends, defines the first tip lateral wall, be equipped with pivot hole 11 and arc hole 12 on the first tip lateral wall, as before, the movable frame 2 has first lateral wall 212, wherein the lateral wall that is located the first side 3 of movable frame 2, second side 4 both ends can be defined as the second tip lateral wall, two second tip lateral walls all are equipped with pivot lug 24 and the slip lug 25 that corresponds with above-mentioned pivot hole 11, arc hole 12 respectively, pivot lug 24 can block corresponding pivot hole 11 and rotatable coupling, slip lug 25 can open corresponding arc hole 12 and sliding coupling.

Referring to fig. 3-4 and fig. 7-8, in the present embodiment, the rotating shaft protrusion 24 and the sliding protrusion 25 are both disposed on the side wall of the second end portion of the upper frame 21, when the rotating shaft protrusion 24 and the sliding protrusion 25 of the movable frame 1 are respectively clamped into the rotating shaft hole 11 and the arc hole 12 of the fixed frame 1, the rotating shaft protrusion 24 and the rotating shaft hole 11 which are rotatably connected are used as a rotating shaft therebetween, the arc hole 12 is a sliding rail, and the sliding protrusion 25 is a sliding block, so that the movable frame 2 can rotate relative to the fixed frame 1 around the rotating shaft, thereby opening and closing the access door.

This kind of setting mode can not occupy the inner space of activity frame 2, does benefit to the assembly of decorative board. However, it should be noted that a reserved space should be left between the movable frame 2 and the first side 3 of the fixed frame 1 for the movable frame 2 to rotate relative to the fixed frame 1, so as to prevent the side walls of the first sides 3 of the movable frame and the fixed frame from colliding; alternatively, the upper and lower edges of the sidewall of the first side 3 of the movable frame 2 may be chamfered so as not to contact the fixed frame 1 when rotating.

It can be understood that the fixed frame 1 and the movable frame 2 can also be rotatably connected in other manners to open and close the access door, which is not limited in the present invention, for example, a rotating shaft penetrating through two sides of the fixed frame 1 and the movable frame 2 can be further provided to enable the movable frame 2 to rotate around the rotating shaft relative to the fixed frame 1, and because the arrangement manner needs to occupy the space inside the movable frame 2, i.e., the installation space of the decorative plate, the decorative plate should also adjust the corresponding structure, for example, a groove is provided at the rotating shaft, so as to normally install the decorative plate.

Fixed frame 1 and movable frame 2 still are equipped with fixed subassembly at second side 4 in this embodiment, and the two can be fixed mutually through fixed subassembly, make the access door keep at the closed condition. Specifically, the fixing component in this embodiment is a push switch component.

As shown in fig. 1, the second side 4 of the fixed frame 1 is provided with a mounting plate 13, the bottom of the second side 4 of the movable frame 2 is provided with a pressing block 26, the position of the pressing block 26 corresponds to the mounting plate 13, the push switch assembly can be mounted on the mounting plate 13, and the pressing block 26 can control the opening and closing of the push switch assembly.

When the access door is in a closed state, the fixed frame 1 and the movable frame 2 are fixed through the press switch assembly; when the access door needs to be opened, the second side 4 of the movable frame 2 is pressed, the pressing block 26 at the bottom of the movable frame can trigger the pressing switch assembly, so that the pressing switch assembly is opened, the movable frame 2 is no longer fixed on the fixed frame 1 and rotates to be opened, and the access door is opened.

It is to be understood that the access door may be opened and closed by other structures, and the fixing component may also be other structures besides the push switch component.

In this embodiment, when the access door is in the closed state, the upper surface of the movable frame 2 is flush with the upper surface 1 of the fixed frame 1. After the arrangement, when the access door is in a closed state, the upper surfaces of the fixed frame 1, the movable frame 2 and the decorative plate are kept flat, and after the access door is installed on a wall body or a suspended ceiling, the access door can be integrated with the surrounding wall body or the suspended ceiling, so that the access door is more attractive.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
