[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3 The utility model provides an embodiment: a manhole cover seat plate that can be precisely positioned, including a base 1, which serves as the foundation of the entire device to ensure that other components are stably positioned. A sealing ring 15 is fixedly connected to the top of the base 1. The sealing ring 15 is used to provide an additional sealing effect when the cover 3 is closed, thereby preventing liquid or gas leakage. The demand for sealing performance in different environments ensures the applicability and reliability of the device. The right side of the base 1 is rotatably connected to a connecting rod 2. The connecting rod 2 is an important component, which is connected to the right side of the base 1 through a rotating mechanism.

[0033] The outside of the base 1 is fixedly connected with a plurality of protrusions 4, which are structures fixed to the outside of the base 1. A cavity 5 is opened inside the protrusion 4, and a telescopic component is provided inside the cavity 5. The telescopic component includes a spring 6, one end of the spring 6 is fixedly connected to the bottom of the cavity 5, and the other end of the spring 6 is fixedly connected to a pressure rod 7. The outside of the pressure rod 7 is slidably connected to the inner wall of the cavity 5. The top of the protrusion 4 is rotatably connected to a rotating plate 8, which is installed on the top of the protrusion 4 and works in conjunction with the telescopic component. The position of the rotating plate 8 can be adjusted according to actual needs to adapt to different usage conditions. The telescopic component can adjust the position of the rotating plate 8. The inside of the base 1 is fixedly connected with a plurality of positioning columns 9, and the top of the base 1 is detachably connected to a cover plate 3, allowing the cover plate 3 to rotate smoothly when opening and closing. This design not only facilitates operation, but also reduces possible damage to the device during operation.

[0034] The bottom of the cover plate 3 contacts the outside of the rotating plate 8, and the bottom of the cover plate 3 contacts the top of the positioning column 9. The cover plate 3 is the main component placed on the top of the base 1. Its bottom contacts the rotating plate 8 and the top of the positioning column 9. A plurality of positioning grooves 10 are provided on the outside of the cover plate 3. A plurality of positioning columns 9 are also fixed inside the base 1. These positioning columns 9 cooperate with the positioning grooves 10 at the bottom of the cover plate 3 to further enhance the accuracy and stability of positioning. The outside of the rotating plate 8 is engaged with the inner wall of the positioning groove 10. A plurality of positioning grooves 10 are provided on the outside of the cover plate 3. These grooves are engaged with the outside of the rotating plate 8 to ensure that the cover plate 3 can be tightly locked in place when closed.

[0035] Reference Figures 4 and 5 The left side of the cover plate 3 is fixedly connected with a handle 2, and the top of the cover plate 3 is provided with a fixing component, which can assist in fixing the connecting rod 2. The fixing component includes a fixing block 11, and the bottom of the fixing block 11 is fixedly connected to the top of the cover plate 3. The top of the cover plate 3 is rotatably connected with an adjusting plate 12. The left internal thread of the connecting rod 2 is connected with a handle 13. Rotate the connecting rod 2 and put the handle 13 into the inside of the adjusting plate 12. As the handle 13 rotates, the left side of the adjusting plate 12 will rotate upward, and while rotating, the left side will slide along the outside of the fixed block 11. The external thread of the handle 13 is connected to the inside of the right side of the adjusting plate 12. By rotating the handle 13, the position of the adjusting plate 12 can be adjusted, thereby assisting in fixing the connecting rod 2.

[0036] The bottom of the handle 13 and the top of the cover 3 and the left side of the fixed block 11 are provided with a slot 14, and the left side of the adjustment plate 12 is engaged with the inner wall of the slot 14, and is engaged with the inner wall of the slot 14 during the movement. When the adjustment plate 12 is clamped with the top of the fixed block 11, stop turning the handle 13, ensuring that the adjustment plate 12 can remain in the appropriate position after adjustment, thereby improving the stability of the entire structure. The internal thread connection of the cover 3 is connected with multiple bolts 16, and the external thread connection of the bolts 16 is connected with nuts. The bolts 16 and the nuts cooperate to finally fix the base 1 and the cover 3. This design ensures the firmness and sealing of the entire structure, so that it can work normally under various environmental conditions.

[0037] Working principle: First, place the base 1 to a suitable position, place the sealing ring 15 on the top of 1, then place the cover 3 on the top of the base 1 and rotate it to adjust. As the cover 3 rotates, the bottom contacts the positioning column 9. At the same time, the bottom of the cover 3 will squeeze the turn plate 8. When the turn plate 8 rotates, the pressure rod 7 is compressed and slides downward inside the spring 6. At this time, the cavity 5 is compressed, and the turn plate 8 is engaged with the positioning groove 10. After being compressed, the spring 6 will generate a reaction force on the pressure rod 7, so that the turn plate 8 and the positioning groove 10 are engaged more tightly.

[0038] Then rotate the connecting rod 2 and put the handle 13 into the inside of the adjustment plate 12. As the handle 13 is rotated, the left side of the adjustment plate 12 will rotate upward. While rotating, the left side slides along the outside of the fixed block 11 and engages with the inner wall of the slot 14 during the movement. When the adjustment plate 12 is clamped with the top of the fixed block 11, stop rotating the handle 13, and the connecting rod 2 can be connected to the cover plate 3. Then use the bolts 16 to fix the base 1 and the cover plate 3.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
