[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Please see Figure 1 , Figure 3 and Figure 4This utility model provides a technical solution: a skylight inspection port with a switch and lock function, including a frame 1, which serves as the fixed frame and basic carrier of the skylight inspection port. A cover plate 2 is rotatably connected inside the frame 1 for closing or opening the skylight inspection port. Under normal conditions, it covers the opening. A switch mechanism 3 is fixedly connected to the top of the frame 1. The switch mechanism 3 includes a connecting piece 31 for stably connecting a limiting groove plate 32 to the frame 1, providing an installation base for the limiting groove plate. The bottom of the connecting piece 31 is fixedly connected to the top of the frame 1, and the top of the connecting piece 31 is fixedly connected to the limiting groove plate 32. Through the groove and the rotating plate 34, the cover plate 2 is closed and locked to prevent accidental opening. The groove of the limiting groove plate 32 is slidably connected to the outside of the rotating plate 34, and the bottom of the rotating plate 34 is rotatably connected to... The top of the cover plate 2 is fixedly connected to a connecting disc 33, which provides a fulcrum for the rotating plate and ensures that the rotating plate can rotate flexibly around it to cooperate with the limiting groove plate 32. The external of the connecting disc 33 is rotatably connected to a rotating plate 34, which realizes the locking and unlocking of the cover plate 2 and is the core action of the inspection port switch operation. The external of the rotating plate 34 is fixedly connected to a limiting spring 35, which provides continuous tension to the rotating plate and ensures that it is stably inserted into the limiting groove plate 32 in the locked state. At the same time, it drives the rotating plate to reset after unlocking. The other end of the limiting spring 35 is fixedly connected to a fixing block 36, which provides a stable fixed end point for the limiting spring and ensures that the spring tension direction is accurate. The bottom of the fixing block 36 is fixedly connected to the top of the cover plate 2, and the bottom of the cover plate 2 is in contact with the top of the sealing ring 41.

[0025] A limiting component 37 is fixedly connected to the outer left side of the cover plate 2. The limiting component 37 includes a telescopic column 371, which is used to initially fix the cover plate 2 in the closed state. The auxiliary switch mechanism 3 enhances the locking effect. The other end of the telescopic column 371 is slidably connected to the inner groove of the frame 1. The other end of the return spring 372 is fixedly connected to the outer left side of the cover plate 2. One end of the telescopic column 371 is fixedly connected to the outer left side of the cover plate 2. The telescopic column 371 is provided with a return spring 372 inside, which provides an outward pushing force to the telescopic column, ensuring that it can automatically slide into the groove of the frame 1 when the cover plate is closed, so as to achieve initial fixation. A circular groove is opened on the inner left side of the frame 1 to restrict the telescopic column 371 sliding on the frame 1, thus initially fixing the cover plate 2.

[0026] like Figure 1 and Figure 2As shown, a waterproof mechanism 4 is fixedly connected inside the frame 1. The waterproof mechanism 4 includes a sealing ring 41, which is used to fill the gap between the cover plate and the frame when the cover plate 2 is closed. The sealing ring 41 is fixedly connected to the inside of the frame 1. Barrier strips 42 are fixedly connected to the top four sides of the frame 1, which are used to prevent liquid from flowing directly to the inside when it flows to the top of the frame. Multiple drainage protrusions 43 are fixedly connected to the top of the barrier strips 42, which are used to guide the rainwater on the barrier strips into droplets and prevent the rainwater from forming a water flow along the edge of the barrier strips, thus reducing the possibility of water flowing over the barrier strips.

[0027] Water-absorbing components 44 are fixedly connected to the top four sides of the frame 1. Each water-absorbing component 44 includes water-absorbing cotton 441, which is used to absorb a small amount of rainwater or dew that passes through the barrier strip 42, preventing it from flowing further to the sealing ring 41 or seeping into the skylight. Multiple placement slots 442 are fixedly connected to the top four sides of the frame 1. Placement slots 442 are opened on the top four sides of the frame 1 to accommodate water-absorbing cotton and prevent the water-absorbing cotton from shifting or being lost.

[0028] Working principle: First, maintenance personnel can directly rotate the rotating plate 34, causing it to rotate around the connecting disc 33. This gradually disengages the rotating plate 34 from the groove of the limiting slot 32. Simultaneously, the limiting spring 35, which is in its natural state, is stretched, generating elastic tension. As the rotating plate 34 completely disengages from the limiting slot 32, the locking state of the cover plate 2 is released, allowing maintenance personnel to flip the cover plate 2. Under the force of the rotating cover plate 2, the telescopic column 371 slides out from the internal groove of the frame 1, compressing its internal return spring 372, thus no longer restricting the cover plate 2. The cover plate 2 can then... After the cover plate 2 is opened smoothly, revealing the interior space of the courtyard, and the maintenance work is completed, when closing the cover plate 2, first flip the cover plate 2 downwards until it contacts the frame 1. During the closing process of the cover plate 2, the telescopic column 371 automatically slides into the inner circular groove of the frame 1 under the elastic thrust of the return spring 372, forming a preliminary fixation for the cover plate 2. Then, the maintenance personnel release the external force on the rotating plate 34, restrict the spring 35 to contract under its own elastic restoring force, and pull the rotating plate 34 to rotate in the opposite direction around the connecting disc 33 until the rotating plate 34 is re-locked into the groove of the limiting groove plate 32, thus achieving complete locking of the cover plate 2.

[0029] In daily use, when encountering liquids such as rainwater, the barrier strips 42 on the four sides of the top of the frame 1 first block the liquid, and most of the liquid is blocked on the outside. When a small amount of liquid crosses the barrier strip 42, it will be guided by the drainage protrusion 43 on the top of the barrier strip 42 and fall in droplets. As for the residual trace amount of liquid, it will be absorbed by the absorbent cotton 441 placed in the groove 442 on the top of the frame 1. At the same time, the bottom of the cover plate 2 is in close contact with the sealing ring 41 inside the frame 1, further preventing liquid from seeping in and ensuring the waterproof effect of the well inspection port in all aspects.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
