DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0026] The utility model provides a concrete well ring structure with good sealing stability, comprising:

[0027] Concrete well frame 1;

[0028] The well ring 2 is arranged in the opening at the top of the concrete well frame 1;

[0029] An annular connecting block is fixedly installed on the outer wall of the well ring 2, and the annular connecting block is fixedly installed on the inner wall of the concrete well frame 1, so that the well ring 2 and the concrete well frame 1 can be relatively fixed;

[0030] A manhole cover 3 is provided above the manhole ring 2;

[0031] The manhole cover 3 can seal the manhole ring 2 to prevent rainwater from outside from flowing into the concrete manhole frame 1;

[0032] An annular groove 4 is formed on the upper end surface of the well ring 2;

[0033] The annular member 5 is fixedly mounted on the lower end surface of the manhole cover 3 and is inserted into the annular groove 4;

[0034] Under the action of the annular groove 4 and the annular member 5, the positions of the manhole cover 3 and the manhole ring 2 can be relatively fixed, so that the manhole cover 3 can better seal the manhole ring 2;

[0035] The locking mechanism is provided on the lower end surface of the manhole cover 3 and is used to lock the manhole cover 3 and the manhole ring 2 with each other.

[0036] Specifically, the locking mechanism includes;

[0037] A pair of fixed blocks 6 are fixedly mounted on the lower end surface of the manhole cover 3;

[0038] A bidirectional threaded rod 7 is rotatably mounted between a pair of fixed blocks 6, with both ends passing through the pair of fixed blocks 6 respectively;

[0039] The sliding blocks 8 are a pair and are respectively threadedly connected to both ends of the bidirectional threaded rod 7;

[0040] An L-shaped locking frame 9, one end of which is fixedly connected to the lower end surface of the sliding block 8, and the outer surface of the other end is in contact with the lower end surface of the well ring 2;

[0041] The rotation of the bidirectional threaded rod 7 can drive a pair of sliding blocks 8 to move closer to or away from each other. When moving away from each other, it can drive a pair of L-shaped locking frames 9 to move away from each other, so that the outer surface of one end of the L-shaped locking frame 9 contacts the lower end surface of the well ring 2, so that the manhole cover 3 is relatively locked to the well ring 2 to prevent the manhole cover 3 from opening. At the same time, when the pair of L-shaped locking frames 9 are close to each other, they can move away from the well ring 2, making it convenient for the staff to separate the manhole cover 3 from the well ring 2.

[0042] Specifically, a first bevel gear 10 is fixedly mounted on the outer surface of the bidirectional threaded rod 7, a rotating shaft 11 is rotatably mounted inside the manhole cover 3, a second bevel gear 12 meshing with the first bevel gear 10 is fixedly mounted on the lower end surface of the rotating shaft 11, and a square groove 13 is formed in the upper end surface of the rotating shaft 11;

[0043] The staff inserts one end of an external square wrench into the square slot 13 and rotates the square wrench at the same time, so that the rotating shaft 11 drives the second bevel gear 12 to rotate. The rotation of the second bevel gear 12 can drive the first bevel gear 10 and the bidirectional threaded rod 7 to rotate simultaneously.

[0044] Specifically, a rubber pad 14 is provided on the inner lower end surface of the annular groove 4, and an annular placement groove 15 is formed on the lower end surface of the annular member 5. A rubber ring 16 is provided in the annular placement groove 15, and the lower end of the outer surface of the rubber ring 16 contacts the upper end surface of the rubber pad 15;

[0045] Under the action of the rubber pad 14 and the rubber ring 16, the gap between the annular groove 4 and the annular member 5 can be sealed to prevent external rainwater from penetrating.

[0046] Specifically, a limiting groove 17 is formed on the lower end surface of the manhole cover 3, and a limiting block 18 is fixedly mounted on the upper end surface of the sliding block 8 and is slidably connected to the limiting groove 17;

[0047] Under the action of the limiting groove 17 and the limiting block 18, the sliding block 8 can remain stable while sliding.

[0048] Working principle: When in use, the staff lifts the manhole cover 3 and inserts the annular member 5 into the annular groove 4. At this time, the staff stands on the upper end surface of the manhole cover 3. At this time, under the action of gravity, the rubber pad 14 and the rubber ring 16 are compressed. At this time, the staff inserts one end of the external square wrench into the square groove 13 and rotates the square wrench at the same time. The rotation of the square wrench drives the rotating shaft 11 and the second bevel gear 12 to rotate. The rotation of the second bevel gear 12 can drive the first bevel gear 10 and the bidirectional threaded rod 7 to rotate at the same time. At this time, the rotation of the bidirectional threaded rod 7 can drive A pair of sliding blocks 8 move away from each other. When moving away from each other, they can drive a pair of L-shaped locking frames 9 to move away from each other, so that the outer surface of one end of the L-shaped locking frame 9 contacts the lower end surface of the well ring 2, so that the manhole cover 3 and the well ring 2 are relatively locked, and the well ring 2 is sealed to prevent external rainwater from seeping into the concrete well frame 1, bringing convenience to people. At the same time, when the manhole cover 3 needs to be disassembled, it is only necessary to rotate the square wrench in the opposite direction to make the pair of L-shaped locking frames 9 approach each other and move away from the well ring 2, making it convenient for the staff to separate the manhole cover 3 from the well ring 2, bringing convenience to people.
