[0026] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0027] In the description of the present invention, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] Among the existing inspection openings, one type of inspection opening uses screws to directly fix the shielding plate to the galvanized plate on the back. When the ceiling needs to be inspected, the screws need to be removed first before the shielding plate can be removed and the inspection opening can be opened. After the inspection is completed, the shielding plate needs to be reinstalled on the inspection opening and screwed in to fix it. At the same time, repaint it to complete the decoration. Another type of inspection opening is to fix an inverted Ω steel plate on the back of the shielding plate, which is placed on the top reinforcement. When disassembling, the shielding plate needs to be pushed up and moved to one side before it can be opened. This type of inspection opening requires a large space for pushing upwards in order to install and disassemble.

[0030] Therefore, the above two installation methods of shielding plates will cause difficulty in installing or removing the shielding plates, increase the workload of installing and removing the shielding plates, and thus affect the daily maintenance work of the staff. Therefore, a maintenance port assembly that is easy to disassemble and install is proposed to solve the above problems.

[0031] In this embodiment, the inspection port assembly can be installed on the modular building to facilitate the inspection of the top of the modular building. The modular building includes a box-type body and an inspection port assembly. Specifically, an indoor space is provided inside the box-type body, and the inspection port assembly is installed on the box-type body and is located in the indoor space and below the ceiling. At the same time, the inspection port assembly is spaced apart from the top of the indoor space so that a space is formed between the inspection port assembly and the ceiling for maintenance personnel to inspect the top of the indoor space.

[0032] In this embodiment, the modular building is a steel structure building. Providing an inspection port assembly on the modular building can facilitate maintenance personnel to check or inspect the connection status of the steel structure and perform waterproofing.

[0033] See also Figure 1 and Figure 2 The inspection opening assembly for easy assembly and disassembly of this embodiment includes a fixing member 10, a covering member 20 and a connecting member 30. The fixing member 10 is provided with a maintenance window 11, the covering member 20 covers the maintenance window 11, and the connecting member 30 is connected between the fixing member 10 and the covering member 20, and fastens the covering member 20 to the fixing member 10.

[0034] Specifically, the fixing member 10 is connected to the building and is spaced apart from the ceiling of the building. Specifically, the fixing member 10 can also be set as a decorative plate on the building body and is spaced apart from the ceiling of the building, so that there is space between the fixing member 10 and the ceiling for maintenance personnel to inspect the structure on the top of the building. In this embodiment, a maintenance window 11 for maintenance is provided on the fixing member 10, and the maintenance window 11 vertically penetrates the fixing member 10, so that maintenance personnel can enter the space between the fixing member 10 and the ceiling through the maintenance window 11, or observe the structure on the top of the building through the maintenance window 11.

[0035] At the same time, the shape of the cover 20 is adapted to the maintenance window 11, so that the cover 20 can cover the maintenance window 11 upwards and close the maintenance window 11. That is, the shape and size of the cover 20 are adapted to the maintenance window 11, so that when the cover 20 covers the maintenance window 11, the cover 20 can close the maintenance window 11.

[0036] In addition, the connecting member 30 is provided with a first end and a second end, and the first end is connected to the upper surface of the covering member 20, and the second end can extend from the first end toward the fixing member 10 and abut against the upper surface of the fixing member 10 to fasten the covering member 20 in the maintenance window 11.

[0037] In this embodiment, a protruding first boss 12 is formed on the inner peripheral wall of the maintenance window 11, and a protruding second boss 21 is arranged on the outer peripheral wall of the cover member 20, and the upper end of the second boss 21 is used to abut against the lower surface of the first boss 12, so that when the cover member 20 is tightly covered in the maintenance window 11 by the connecting member 30, the upper surface of the second boss 21 can be pressed on the lower surface of the first boss 12, and a limit is formed between the cover member 20 and the fixing member 10.

[0038] It should be noted that the cover 20 covers and seals the maintenance window 11 of the fixing member 10 from bottom to top, and under the tightening action of the connecting member 30, the cover 20 can be stably retained in the maintenance window 11, thereby completing the installation of the cover 20. When the maintenance window 11 needs to be opened, the connecting member 30 needs to be separated from the fixing member 10 and the cover 20 needs to be moved downward to open the maintenance window 11.

[0039] See also Figure 1In this embodiment, the maintenance window 11 is set as a rectangular through hole, so that maintenance personnel can inspect the structure on the top of the building through the maintenance window 11 to ensure the safety of the building. It should be noted that the maintenance window 11 can also be set as a through hole in a circular, triangular or diamond shape according to actual needs to facilitate the use of maintenance personnel.

[0040] Meanwhile, the cover 20 is a gypsum board, so that the cover 20 can be fireproof, ensuring the safety of the inspection port assembly. Of course, the cover 20 can also be set as a calcium silicate board, a cement fiber board or a glass magnesium board, so that the cover 20 has fireproof performance.

[0041] In addition, it should be noted that when the covering member 20 is covered in the maintenance window 11, the bottom of the covering member 20 is kept flush with the bottom of the fixing member 10 to ensure the beauty of the inspection opening.

[0042] See also Figure 2 A metal edge strip 22 is provided on the outer peripheral wall of the covering member 20 to enhance the structural strength of the edge of the covering member 20 .

[0043] See also Figure 1 and Figure 2 In this embodiment, the connecting member 30 can be configured as a spring clip 31. The first end of the spring clip 31 is fixed to the top of the cover 20, and the second end of the spring clip 31 can rotate relative to the cover 20. When the cover 20 is covered in the maintenance window 11, the second end of the spring clip 31 can rotate toward the top of the fixing member 10 under the action of elastic force, and abut against the upper surface of the fixing member 10, so as to fix the cover 20 on the fixing member 10. That is, when the cover 20 is covered in the maintenance window 11, the second end of the spring clip 31 is rotated toward the upper surface of the cover 20 in advance to avoid the first boss 12. After the cover 20 is placed in the maintenance window 11, the second end of the spring clip 31 automatically rotates toward the upper surface of the fixing member 10 under the action of elastic force, and abuts against the upper surface of the fixing member 10, so as to fasten and press the cover 20 in the maintenance window 11.

[0044] When it is necessary to remove the cover 20 from the maintenance window 11, a downward pulling force is applied to the cover 20, so that the second end of the spring clip 31 rotates toward the side away from the fixing member 10, and after the second end of the spring clip 31 is disengaged from the top of the fixing member 10, the cover 20 can be removed from the maintenance window 11.

[0045] It should be noted that there are at least two spring clips 31 , which are distributed on two opposite sides of the cover 20 , so that the cover 20 can be stably covered in the maintenance window 11 .

[0046] See also Figure 3 and Figure 4 In some other embodiments, the connecting member 30 may be configured as a rotating member 32 and a locking member 33. The locking member 33 is fixed to the rotating member 32, and the rotating member 32 is configured as the first end of the connecting member 30, and the locking member 33 is configured as the second end of the connecting member 30. Specifically, the rotating member 32 is rotatably connected to the covering member 20 and protrudes from the upper surface of the covering member 20, and the locking member 33 is fixed to the top of the rotating member 32, and can be driven by the rotating member 32 to rotate toward the top of the fixing member 10, so as to be able to abut against the upper surface of the fixing member 10. That is, the locking member 33 is installed on the top of the rotating member 32 and is located above the covering member 20, and can rotate with the rotation of the rotating member 32, so that one end of the locking member 33 rotates to the top of the fixing member 10, so that under the action of gravity, one end of the locking member 33 abuts against the upper surface of the fixing member 10, thereby supporting the covering member 20, so that the covering member 20 is retained in the maintenance window 11.

[0047] When the cover 20 needs to be removed from the maintenance window 11 , the rotating member 32 only needs to be rotated to drive the locking member 33 to rotate, so that the locking member 33 and the upper surface of the fixing member 10 are disengaged from each other, and then the cover 20 is moved downward to be removed from the maintenance window 11 .

[0048] See also Figure 5 and Figure 6 In some other embodiments, the connecting member 30 may also be configured as a push lock 34 and a lock hook 35. The lock hook 35 is configured as a first end portion of the connecting member 30, and the push lock 34 is configured as a second end portion of the connecting member 30. Specifically, the push lock 34 is fixed to the upper surface of the fixing member 10 and extends toward the maintenance window 11. One end portion of the lock hook 35 is fixed to the upper surface of the covering member 20, and the other end extends upward and can be locked in the push lock 34, so that when the covering member 20 is covered in the maintenance window 11, the lock hook 35 can be locked in the push lock 34, thereby enabling the covering member 20 to be installed in the maintenance window 11.

[0049] It should be noted that since the push lock 34 can lock or unlock the lock hook 35 by pressing, the cover 20 can be fixed in the maintenance window 11 by pressing, and the cover 20 can also be released from the maintenance window 11 by pressing, thereby facilitating the closing or opening of the cover 20.

[0050] See also Figure 2 In this embodiment, the inspection port assembly further includes a plugging member 40. The plugging member 40 is connected between the fixing member 10 and the covering member 20, so that when the covering member 20 is covered in the maintenance window 11, the plugging member 40 can fill the gap between the fixing member 10 and the covering member 20 to prevent water leakage between the fixing member 10 and the covering member 20.

[0051] Meanwhile, the blocking member 40 is a fireproof adhesive, and the fireproof adhesive is arranged on the peripheral side of the cover member 20, so that when the cover member 20 is covered in the maintenance window 11, the blocking member 40 can be sealed between the fixing member 10 and the cover member 20. It should be noted that the blocking member 40 can be set as a material with fireproof function such as an intumescent fireproof tape and a fireproof adhesive.

[0052] To sum up, in the inspection port assembly, the cover 20 is installed in the maintenance window 11 of the fixing member 10 through the connecting member 30, so that the cover 20 can be installed in the maintenance window 11 from bottom to top, and the cover 20 can be removed from the maintenance window 11 from top to bottom, thereby facilitating the assembly and disassembly of the cover 20 and avoiding the opening and closing of the cover 20 being affected by the spacing space between the inspection port assembly and the ceiling being too small.
