[0031] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: an electric manhole cover that is easy to lift, including a base 1, a cover body 2 is arranged on the top of the base 1, a sealing ring 3 is arranged between the base 1 and the cover body 2, the sealing ring 3 is convenient for sealing the connection between the base 1 and the cover body 2, the middle part of the cover body 2 is rotatably connected with a connecting rod 7, the outer periphery of the connecting rod 7 is fixedly connected with a gear 8, when the connecting rod 7 rotates, it will drive the gear 8 to rotate at the same time, the inside of the cover body 2 is slidably connected with a rack plate 2 10 and a rack plate 1 9, the rack plate 2 10 and the rack plate 1 9 are meshed with the gear 8, when the gear 8 rotates, it will drive the rack plate 1 9 and the rack plate 2 10 to move at the same time.
[0032] Reference Figure 2 and Figure 3One end of the rack plate 2 10 and the rack plate 1 9 are fixedly connected with a buckle 11, and a slot 12 is opened inside the base 1, and the buckle 11 and the slot 12 are snapped together. When the rack plate 2 10 and the rack plate 1 9 move, the buckle 11 will be driven to move at the same time, so that the buckle 11 is disengaged from the slot 12. When the buckle 11 is disengaged from the slot 12, the base 1 and the cover body 2 can be easily separated. On the contrary, the base 1 and the cover body 2 can be conveniently connected and fixed, thereby preventing the manhole cover from being displaced and lost when subjected to external force.
[0033] Reference Figure 3 and Figure 4 Specifically, there are two buckles 11, and both buckles 11 are slidably connected to the inside of the cover body 2. The two buckles 11 can make the cover body 2 and the base 1 connected more firmly, thereby preventing deviation. A connecting assembly is provided on the top of the connecting rod 7, and the connecting assembly includes a knob 5. The knob 5 is arranged on the top of the connecting rod 7, and the bottom of the knob 5 is fixedly connected to a limiting block 13. A limiting groove 14 is provided on the top of the connecting rod 7. The limiting block 13 and the limiting groove 14 can conveniently connect the connecting rod 7 and the knob 5, and the knob 5 is convenient for the staff to drive the connecting rod 7 to rotate, and the limiting block 13 is slidably connected to the middle of the limiting groove 14.
[0034] Reference Figure 4 and Figure 5 A slide groove 6 and a connecting groove 17 are provided on the top of the cover body 2, and a handle 4 is slidably connected to the middle of the slide groove 6, and the handle 4 and the connecting groove 17 are snap-fitted. Specifically, two handles 4 are provided, and the two handles 4 are slidably connected to the middle of the cover body 2. The two handles 4 are convenient for the staff to drive the cover body 2 to move, so that the cover body 2 and the base 1 are separated.

[0035] Working principle: When the base 1 and the cover body 2 are separated or connected and fixed, the limit block 13 is inserted into the middle of the limit groove 14 through the knob 5. When the limit block 13 is inserted into the middle of the limit groove 14, the knob 5 is turned. When the knob 5 is turned, the connecting rod 7 is driven to rotate. When the connecting rod 7 rotates, the gear 8 is driven to rotate. When the gear 8 rotates, the rack plate 1 9 and the rack plate 2 10 are driven to move at the same time. When the rack plate 1 9 and the rack plate 2 10 move, the buckle 11 is driven to move, so that the buckle 11 is disengaged from the slot 12. When the buckle 11 is disengaged from the slot 12, the base 1 and the cover body 2 can be easily separated. On the contrary, the base 1 and the cover body 2 can be conveniently connected and fixed, thereby preventing the manhole cover from being displaced and lost when subjected to external force.
[0036] When the cover body 2 needs to be lifted, the handle 4 is placed into the middle of the slide groove 6 and the handle 4 is pressed to squeeze the top plate 16. When the top plate 16 is squeezed, the spring 15 is squeezed, and the handle 4 squeezes the top plate 16 and drives the handle 4 to slide, so that the handle 4 slides into the middle of the connecting groove 17. When the handle 4 slides into the middle of the connecting groove 17, it is convenient for the staff to lift the cover body 2, and then it is convenient to separate the cover body 2 and the base 1.
