[0067] In this embodiment, the inspection port can be formed by splicing the first profile body 100, and the first profile body 100 is connected to the ceiling floor 600 through the first groove structure 101 to realize the edging of the inspection port outer frame formed by the first profile body 100, wherein a first fixing portion 200 is provided on the side of the first profile body 100 close to the first opening 102, and the first profile body 100 can be fixed to the wall through the first fixing portion 200 to prevent the outer frame of the inspection port from warping or concave deformation, thereby ensuring that the outer frame of the inspection port is tightly connected to the inspection cover 20.

[0068] For example, please combine Figure 3As shown in the figure, when installing the inspection port outer frame profile 10, the ceiling floor 600 close to the inspection port can be inserted through the first opening 102, so that the first groove structure 101 is engaged with the ceiling floor 600, and then the ceiling floor 600 can be fixed to the roof through the first fixing part 200, which is equivalent to fixing the ceiling floor 600 at the inspection port position through the first fixing part 200 to prevent the ceiling floor 600 from being deformed at the inspection port position. The installation is convenient and the use is easy.

[0069] Specifically, see Figure 2 The first profile body 100 includes: a first plate body 110 and a second plate body 120. One end of the first plate body 110 is connected to a first fixing portion 200, and the other end is connected to a first connecting portion 300. The second plate body 120 is connected to a side of the first connecting portion 300 away from the first plate body 110. The second plate body 120, the first connecting portion 300 and the first plate body 110 are connected in sequence to form a first groove structure 101 with a first opening 102.

[0070] In this embodiment, the first plate body 110 and the second plate body 120 form a first groove structure 101 of the first opening 102. When the inspection port outer frame profile 10 is installed, the ceiling floor 600 can be inserted through the first opening 102, and the first groove structure 101 is clamped on the ceiling floor 600. The first plate body 110 is provided with a first fixing portion 200, that is, the first plate body 110 can be fixed to the wall through the first fixing portion 200. On the one hand, the inspection port outer frame profile 10 can be prevented from being deformed due to the deformation of the ceiling floor 600. On the other hand, the inspection port outer frame profile 10 can prevent the deformation of the ceiling floor 600 at the inspection port position, and strengthen the structural strength of the ceiling floor 600 at the inspection port position to ensure that the inspection port outer frame is tightly connected to the inspection cover 20.

[0071] Specifically, see Figure 2 The first connecting portion 300 includes: a first vertical edge 310, a first step surface 320 and a second vertical edge 330. The first vertical edge 310 is connected to one end of the first plate body 110 away from the first fixing portion 200. The first step surface 320 is connected to one end of the first vertical edge 310 away from the first plate body 110. One end of the second vertical edge 330 is connected to one end of the first step surface 320 away from the first vertical edge 310, and the other end is connected to the second plate body 120. The first vertical edge 310, the first step surface 320 and the second vertical edge 330 are connected to form a step structure.

[0072] In this embodiment, the first vertical edge 310, the first step surface 320 and the second vertical edge 330 are connected to form a step structure. On the one hand, the outer side surface of the step structure is used to cooperate with the inspection cover 20 to prevent the inspection cover 20 from shaking at the inspection port position. On the other hand, the inner side surface of the step structure is clamped with the ceiling floor 600 to fix the ceiling floor 600 to the first groove structure 101, which can strengthen the firm connection between the ceiling floor 600 and the inspection port outer frame profile 10 and prevent the ceiling floor 600 and the inspection port outer frame profile 10 from loosening.

[0073] Specifically, see Figure 2 The first fixing portion 200 includes a third vertical edge 210 , and the third vertical edge 210 is formed by extending upward from the first plate body 110 .

[0074] In this embodiment, the third vertical edge 210 can be fixedly connected to the wall through a leveling assembly 700. For example, the third vertical edge 210 can be fixed to the wall through a keel, providing an installation structure for the inspection port outer frame profile 10. The structure is simple, easy to manufacture, low cost, convenient to install, and highly practical.

[0075] For example, when installing the inspection port outer frame profile 10, the inspection port outer frame profile 10 and the ceiling floor 600 are pre-aligned so that the first groove structure 101 is clamped on the ceiling floor 600, and can be fitted with the vertical keel 720 through the third vertical edge 210. Then, the third vertical edge 210 and the vertical keel 720 can be fixed with screws. At this time, the first plate body 110 can be abutted against the bottom of the vertical keel 720, and then screws can be passed through the second plate body 120, the ceiling floor 600, and the first plate body 110 from the bottom of the ceiling floor 600 in sequence and fixedly connected to the vertical keel 720, so that the ceiling floor 600 is fixed to the vertical keel 720 to prevent the ceiling floor 600 from deformation at the inspection port position.

[0076] Embodiment 2:

[0077] See also Figure 3 and Figure 4 The present embodiment provides an inspection port assembly, which includes: an inspection port outer frame profile 10, an inspection cover plate 20 and an inspection port inner frame 30 as in the above embodiment, the inspection port outer frame profile 10 is used to be installed in the inspection port to form an inspection port outer frame, the inspection cover plate 20 is used to close the inspection port, the inspection port inner frame 30 is wrapped around the edge of the inspection cover plate 20, and the inspection port inner frame 30 is matched with the inspection port outer frame.

[0078] In this embodiment, since the inspection opening outer frame profile 10 has a first fixing portion 200 and the first fixing portion 200 can be fixed to the wall, the inspection opening outer frame profile 10 can strengthen the connection with the wall and avoid deformation due to deformation of the ceiling floor 600, thereby ensuring that the inspection opening outer frame is tightly connected to the inspection cover plate 20.

[0079] For example, four inspection port outer frame profiles 10 can be connected by closing the ends to form an inspection port outer frame, wherein the four inspection port outer frame profiles 10 can include front, rear, left and right inspection port outer frame profiles 10, the left and right inspection port outer frame profiles 10 can be fixedly connected to the vertical keel 720 by screws, and the front and rear inspection port outer frame profiles 10 do not need to be fixedly connected to the vertical keel 720.

[0080] Specifically, see Figure 5 The inspection port inner frame 30 includes: a second profile body 400 and a second connecting portion 500. The second profile body 400 includes a second groove structure 401 having a second opening 402. The second groove structure is used to wrap around the edges of the inspection cover 20. The second connecting portion 500 is arranged on a side of the second profile body 400 away from the second opening 402. The second connecting portion 500 is used to cooperate with the first connecting portion 300 for connection.

[0081] In this embodiment, the second profile body 400 is wrapped around the edges of the inspection cover 20 through the second groove structure 401 to form a edging structure for the inspection cover 20, so as to achieve the purpose of protecting the inspection cover 20, prevent the inspection cover 20 from being damaged due to collision, extend the service life of the inspection cover 20, and facilitate installation and use.

[0082] For example, when the inspection port inner frame 30 is in place, the inspection cover 20 can be inserted from the second opening 402 so that the edges of the inspection cover 20 are wrapped by the inspection port inner frame 30 to prevent the inspection cover 20 from being damaged due to collision, thereby extending the service life of the inspection cover 20.

[0083] Specifically, see Figure 5 The second profile body 400 includes: a third plate body 410 and a fourth plate body 420, and the fourth plate body 420 is connected to the third plate body 410 through the second connecting portion 500 to form a second groove structure.

[0084] In this embodiment, the fourth plate body 420 is connected to the third plate body 410 to form a second groove structure, which has a simple structure, is easy to implement, and has low cost. The inspection cover 20 can be stuck between the third plate body 410 and the fourth plate body 420. The second groove structure 401 can form a edging structure for the inspection cover 20 to achieve the purpose of protecting the inspection cover 20.

[0085] For example, after the inspection cover 20 is inserted from the second opening, the upper surface of the edge of the inspection cover 20 can be fitted with the third plate body 410, that is, the upper surface of the edge of the inspection cover 20 can be wrapped and covered by the third plate body 410 to protect the upper surface of the edge of the inspection cover 20, and the lower surface of the edge of the inspection cover 20 can be fitted with the fourth plate body 420, that is, the lower surface of the edge of the inspection cover 20 can be wrapped and covered by the fourth plate body 420 to protect the lower surface of the edge of the inspection cover 20.

[0086] Specifically, see Figure 5 The second connecting portion 500 includes: a fifth vertical edge 510, a second step surface 520 and a fourth vertical edge 530. The fifth vertical edge 510 extends downward from the third plate body 410. The second step surface 520 is connected to one end of the fifth vertical edge 510 away from the third plate body 410. One end of the fourth vertical edge 530 is connected to one end of the second step surface 520 away from the fifth vertical edge 510, and the other end is connected to the fourth plate body 420. The fifth vertical edge 510, the second step surface 520 and the fourth vertical edge 530 are connected to form an inverted step structure for matching and connecting with the first connecting portion 300.

[0087] In this embodiment, the fifth vertical edge 510, the second step surface 520 and the fourth vertical edge 530 are connected to form an inverted step structure. On the one hand, the outer side surface of the inverted step structure is used to cooperate with the inspection port outer frame profile 10 to prevent the inspection cover 20 from shaking at the inspection port position. On the other hand, the inner side surface of the inverted step structure is clamped with the inspection cover 20 to fix the inspection cover 20 to the second groove structure, which can strengthen the firm connection between the inspection cover 20 and the inspection port inner frame 30 and prevent the inspection cover 20 and the inspection port inner frame 30 from loosening.

[0088] For example, when the inspection port needs to be closed, the inspection cover 20 can be closed on the inspection port outer frame so that the inverted step structure matches the step structure of the inspection port outer frame, thereby achieving a stable connection between the inspection cover 20 and the inspection port outer frame.

[0089] Specifically, see Figure 4 The inspection cover 20 includes: a first substrate layer 21 and a second substrate layer 22. The second substrate layer 22 is stacked and connected to the first substrate layer 21 to form a second stacked body 23 with a second staggered structure 24. The second stacked body 23 is connected to the second groove structure through the second staggered structure 24.

[0090] In this embodiment, the second substrate layer 22 and the first substrate layer 21 are spliced ​​to form the inspection cover 20, and a staggered structure is formed on the edges of the inspection cover 20 to facilitate snap-in with the second groove structure. It is easy to manufacture and install, and can reduce production costs.

[0091] For example, the first substrate layer 21 can be used as a bottom plate, and the second substrate layer 22 is laid on the first substrate layer 21. The size of the second substrate layer 22 can be smaller than that of the first substrate layer 21. Then, the second substrate layer 22 and the first substrate layer 21 can be pressed and bonded together with glue, so that the first substrate layer 21 and the second substrate layer 22 form a second stacked body 23 with a second staggered structure 24, which is easy to manufacture and install, and can reduce production costs.
