[0008] Preferably, the portion of the connecting plate located between the top surface of the base plate and the bottom of the external thread is set in an inclined state, with the inclination direction being such that the higher the horizontal height, the smaller the outer diameter.

[0009] Preferably, the outer diameter of the base plate is greater than the maximum outer diameter of the connecting plate, and the outer diameter of the sealing plate is greater than the minimum outer diameter of the connecting plate and less than the maximum outer diameter of the connecting plate.

[0010] Preferably, multiple handles are provided at equal angles on the circumferential surface of the sealing plate.

[0011] Preferably, the maximum vertical distance between the outer side of the handle and the circumferential surface of the sealing plate is set to half the difference between the maximum outer diameter of the connecting plate and the outer diameter of the sealing plate.

[0012] Preferably, multiple sets of fixing rods are arranged at equal angles on the circumferential surface of the sealing plate, and each set of fixing rods is located at the middle of two adjacent handles.

[0013] Preferably, the length of the fixing rod is less than 1 cm.

[0014] Preferably, the bottom of the base plate is provided with multiple positioning plates that simultaneously abut against the inner wall of the septic tank.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] like Figure 1 As shown, a specific embodiment of the rotary sealing cover for septic tanks with a handle provided by this utility model includes a base plate 1 and a sealing plate 3. A connecting plate 2 is provided on the top of the base plate 1, as shown in the figure. Figure 2 As shown, the middle sections of the base plate 1 and the connecting plate 2 are respectively opened up, and the upper part of the connecting plate 2 is provided with external threads 5, as shown. Figure 3As shown, the lower part of the sealing plate 3 is provided with an internal thread 8 that is threaded to the external thread 5. The threaded connection between the sealing plate 3 and the connecting plate 2 is achieved through the external thread 5 and the internal thread 8. After the bottom plate 1 is sealed and connected to the septic tank with bolts, there is no need to change the structure of the septic tank. The threaded connection between the sealing plate 3 and the connecting plate 2 enables convenient installation and removal of the sealing plate 3, which can improve work efficiency in subsequent observation and extraction processes.

[0025] like Figure 2 As shown, the bottom of the base plate 1 is provided with multiple positioning plates 4. The multiple positioning plates 4 simultaneously abut against the inner wall of the septic tank for positioning, which is beneficial for the subsequent installation of the base plate 1 on the septic tank. The part of the connecting plate 2 between the top surface of the base plate 1 and the bottom of the external thread 5 is set in an inclined state. The inclined direction is set so that the higher the height, the smaller the outer diameter. The sealing plate 3 is raised by the connecting plate 2 to prevent the sealing plate 3 from being easily soaked by water when it is on the ground. The inclined part of the connecting plate is narrowed to reduce the volume of the sealing plate 3, which is beneficial for the subsequent installation and removal of the sealing plate 3. The outer diameter of the base plate 1 is larger than the maximum outer diameter of the connecting plate 2, and the outer diameter of the sealing plate 3 is larger than the minimum outer diameter of the connecting plate 2 but smaller than the maximum outer diameter of the connecting plate 2, to ensure the coordination of the products.

[0026] like Figure 3 As shown, multiple handles 6 are arranged at equal angles on the circumferential surface of the sealing plate 3. The handles 6 serve as handles to provide force points when rotating the sealing plate 3, thereby improving work efficiency. Multiple sets of fixing rods 7 are arranged at equal angles on the circumferential surface of the sealing plate 3. Each set of fixing rods 7 is located in the middle of two adjacent handles 6. The fixing rods 7 make the circumferential surface of the sealing plate 3 uneven, making it easier to rotate.

[0027] The maximum vertical distance between the outer side of the handle 6 and the circumferential surface of the sealing plate 3 is set to half the difference between the maximum outer diameter of the connecting plate 2 and the outer diameter of the sealing plate 3. If it is too large, it will increase the cost; if it is too small, it will cause difficulty in bearing force. The length of the fixing rod 7 is less than 1cm. The fixing rod 7 can be used as a protrusion, which will not increase the cost too much.

[0028] In use, place the base plate 1 on the septic tank so that multiple positioning plates 4 simultaneously abut against the inner wall of the septic tank. Install the base plate 1 on the septic tank with bolts. Install the sealing plate 3 on the upper part of the connecting plate 2 through the engagement between the internal thread 8 and the external thread 5. Make a preliminary connection through the fixing rod 7. Lock the sealing plate 3 and the connecting plate 2 through the handle 6 to complete the installation. When disassembling, use the handle 6 to initially disassemble and release the locking state. Then rotate the sealing plate 3 through the fixing rod 7 until the disassembly is completed.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
