[0032] Annular base 1, annular base 1 top right side is equipped with assembly groove 11, and assembly groove 11 front and back sides are equipped with circular groove 12;

[0033] Limiting ring 2, limiting ring 2 is fixedly installed in annular base 1 interior center;

[0034] Cover body 3, cover body 3 covers in annular base 1 interior and bottom and limiting ring 2 upper side abutment;

[0035] The connecting block 4 is fixedly installed at the lower part of the right side of the cover body 3, is located inside the assembly groove 11, and is provided with sliding grooves 41 on the front and back sides and matching the positions of the circular grooves 12. The sliding grooves 41 are provided with plug-in assemblies inside, and the plug-in assemblies are respectively plugged into the circular grooves 12. The plug-in assembly specifically comprises a plug-in block 42 slidably assembled in the sliding groove 41, one end of the plug-in block 42 extends into the corresponding circular groove 12, and the other end of the plug-in block 42 is fixedly installed with a first spring 44, one end of the first spring 44 is fixedly connected with the inner wall of the sliding groove 41.

[0036] In the initial state, the cover body 3 is in the closed state with the annular base 1, the two plug-in blocks 42 extend into the two circular grooves 12 under the action of the two first springs 44, and the two plug-in blocks 42 are in a circular state. After the cover body 3 is opened, the two plug-in blocks 42 always remain in the connected state with the two circular grooves 12, and together form a hinged structure, so that the cover body 3 always remains connected with the annular base 1, and the cover body 3 is not easy to be taken off, thereby reducing the risk of loss.

[0037] A circular through hole 311 is formed in the top center of the cover body 3, and a rotating mechanism is installed inside the circular through hole 311. The rotating mechanism comprises a rotating assembly and a driving assembly.

[0038] The rotating assembly comprises a first sleeve 411 and a second sleeve 421, which are arranged in an upper and lower distribution and are rotatably assembled in the circular through hole 311. The first sleeve 411 and the second sleeve 421 are provided with annular grooves 43 on the periphery, and are provided with through grooves 441 on the left and right sides of the top. The inner walls of the four through grooves 441 are provided with clamping grooves 45.

[0039] The two plug-in blocks 42 are provided with pull ropes 46 on the sides close to each other, one end of the pull rope 46 is fixedly connected with the inner wall of the lower annular groove 43, and the driving assembly is plugged into the first sleeve 411 and the second sleeve 421.

[0040] In the initial state, the driving assembly is in the removed state and is not inserted with the first sleeve 411 and the second sleeve 421. When the cover body 3 needs to be completely removed, the staff inserts the driving assembly into the first sleeve 411 and the second sleeve 421, drives the first sleeve 411 and the second sleeve 421 to rotate synchronously through the driving assembly, and then generates a pulling force when the second sleeve 421 rotates, drives the two pull ropes 46 to be wound into the lower annular groove 43, and generates a pulling force when being wound, so that the two insertion blocks 42 synchronously enter the two sliding grooves 41 to complete unlocking. In this way, the connection between the cover body 3 and the annular base 1 is released, the cover body 3 is removed, and the cover body 3 is convenient for maintenance and replacement. When the cover body 3 is installed subsequently, the cover body 3 is aligned with the installation position and is placed in, and then the two insertion blocks 42 are inserted into the two circular grooves 12, which is simple and convenient to operate. The driving assembly is kept by the staff, the manhole cover can be effectively prevented from being easily opened by non-construction personnel, and the safety is effectively improved.

[0041] The driving assembly comprises an insertion rod 5 which is inserted into the first sleeve 411 and the second sleeve 421. A handle 51 is fixedly installed at the upper end of the insertion rod 5. Two driving blocks 52 are fixedly installed at the central part and the lower side of the peripheral part of the insertion rod 5.

[0042] The four driving blocks 52 of the peripheral part of the insertion rod 5 are respectively matched with the positions of the upper and lower two groups of insertion grooves 45. When only the first sleeve 411 needs to be driven to rotate, the insertion rod 5 is aligned with the first sleeve 411 and is inserted. When the two driving blocks 52 at the lower side are aligned with the upper group of clamping grooves 45, the staff rotates the insertion rod 5 to drive the two driving blocks 52 to enter the two clamping grooves 45, and then rotates the first sleeve 411. When the second sleeve 521 is driven to rotate, the operation principle is similar to the above case, which will not be described herein. When the second sleeve 521 is driven to rotate, the upper and lower two driving blocks 52 are respectively matched with the upper and lower clamping grooves 45, and the first sleeve 411 and the second sleeve 421 are synchronously driven to rotate, so that the cover body 3 is conveniently removed.

[0043] A locking groove 6 is formed in the left upper part of the cover body 3. A limiting groove 61 matched with the position of the locking groove 6 is formed in the left side of the annular base 1. A locking block 611 is slidably assembled in the locking groove 6. An inclined surface 62 is formed in the left side of the locking block 611. The locking block 611 extends into the limiting groove 61. A plurality of second springs 63 are fixedly installed at the right side of the locking block 611. One end of each of the plurality of second springs 63 is fixedly connected with the inner wall of the locking groove 6. A connecting rope 64 is fixedly installed at the right side of the locking block 611. One end of the connecting rope 64 is fixedly connected with the inner wall of the upper annular groove 43.

[0044] In the initial state, several springs 63 push the locking block 611 into the limiting groove 61, and then the cover 3 cannot be opened. When the cover 3 needs to be opened, the first sleeve 411 is driven to rotate by the insertion rod 5, the first sleeve 411 drives the connecting rope 64 to be wound in the annular groove 43, that is, the locking block 611 is pulled into the locking groove 6, so that the cover 3 can be opened. When the cover 3 is subsequently placed down, the cover 3 is directly placed down. Because the second sleeve 421 is not rotated, the position of the cover 3 remains unchanged. The cover 3 is directly placed down. When the top of the annular base 1 contacts the inclined surface 62 provided by the locking block 611, a pushing force is generated to push the locking block 611 into the locking groove 6. When the bottom surface of the cover 3 contacts the limiting ring 2, the locking groove 6 is aligned with the limiting groove 61. The several second springs 63 can push the locking block 611 to be connected with the limiting groove 61 again. The operation is quick. In this way, in the daily state, the cover 3 and the annular base 1 are in a locked state, which can effectively prevent non-workers from opening the cover 3 and improve the use safety.

[0045] A closure cover 7 is detachably arranged inside the upper side of the circular through hole 311. The closure cover 7 can close the circular through hole 311 in the daily state. The closure cover 7 can be opened when the first sleeve 411 and the second sleeve 421 need to be rotated.

[0046] The use mode of the device is as follows:

[0047] In use, in the initial state, the cover 3 and the annular base 1 are locked by the locking block 611, and the two insertion blocks 42 are respectively inserted into the two circular grooves 12. When the worker needs to open the cover 3, the worker inserts the insertion rod 5 into the first sleeve 411. When the insertion rod 5 is rotated, the lower two driving blocks 52 are driven by the insertion rod 5 to enter two clamping grooves 45 provided in the first sleeve 411. The first sleeve 411 can be rotated by the insertion rod 5 to release the locking of the cover 3, and then the cover 3 can be opened. Because the two insertion blocks 42 always remain connected with the two circular grooves 12, the cover 3 cannot be completely removed. When the cover 3 is subsequently closed, the cover 3 can be directly pushed to close. When the cover 3 needs to be completely removed, the first sleeve 411 and the second sleeve 421 are driven by the insertion rod 5 to completely unlock the cover 3, which is convenient for replacement. This setting avoids that the worker can simply open or take away the cover 3, thereby increasing the use safety.
