Description

Technical Field

[0001] This utility model relates to the field of composite manhole covers that are easy to open. Background Technology

[0002] Manhole covers are usually placed inside the mounting ring. When it is necessary to open the manhole cover, a crowbar is needed to be inserted into the gap between the manhole cover and the mounting ring to pry it open. Due to the long-term placement of the manhole cover, a lot of stones and other debris will accumulate in the gap between the manhole cover and the mounting ring. After being crushed by vehicle wheels, these stones will make the manhole cover and the mounting ring more tightly bonded, making it more difficult to insert the crowbar into the gap, thus making the manhole cover difficult to open. Utility Model Content

[0003] The present invention aims to provide a composite manhole cover that is easy to open, making it convenient to open the manhole cover.

[0004] To solve the above technical problems, the specific solution adopted by this utility model is as follows:

[0005] A composite manhole cover that is easy to open includes an installation ring installed on the ground. The installation ring has a placement groove inside, in which the manhole cover is placed. The installation ring also has cross-arranged connecting rods with connecting blocks on the connecting rods. The connecting blocks are located at the center of the manhole cover. Support rods are provided on both sides of the connecting rods. The support rods have rotating grooves, and rotating rods are rotatably connected inside the rotating grooves. A rocker arm is provided on the rotating rod, and the rotating rod is located at the center of the rocker arm. Pressing holes are provided at the positions corresponding to the connecting blocks on the manhole cover. One end of the rocker arm is located below the pressing hole for the operator to press through the pressing hole. The other end of the rocker arm has a push rod, which lifts the manhole cover from the bottom when pressed.

[0006] The manhole cover has a drainage hole at the top.

[0007] The pressing hole is equipped with a pressing rod for the operator to use.

[0008] The top of the pressing rod is covered with a rubber anti-slip pad.

[0009] The inner wall of the mounting ring is provided with a groove that is recessed downward from the top of the placement slot, and the connecting rod is placed in the groove.

[0010] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:

[0011] By setting a connecting block and a connecting rod inside the mounting ring, and setting a rocker arm that can rotate back and forth on the connecting rod, the manhole cover is struck by pressing one end of the rocker arm with a pressing rod, causing the manhole cover to loosen from the mounting ring, making it easier for the operator to insert a pry bar to open the manhole cover; this utility model has a simple and reasonable structure, which effectively facilitates the opening of the manhole cover.

[0015] Figures 1-2 As shown, a composite manhole cover that is easy to open includes an installation ring 1 installed on the ground. The installation ring 1 has a placement groove 2 inside, in which a manhole cover 3 is placed. The installation ring 1 has cross-arranged connecting rods 9 inside, and a connecting block 8 on the connecting rod 9. The connecting block 8 is located at the center of the manhole cover 3. Support rods 10 are provided on both sides of the connecting rod 9. The support rods 10 have a rotating groove 11. The rotating groove 11 has a rotating rod 12 rotatably connected inside. The rotating rod 12 has a rocker arm 13, which is located at the center of the rocker arm 13. The manhole cover 3 has a pressing hole 5 at the position corresponding to the connecting block 8. One end of the rocker arm 13 is located below the pressing hole 5 for the operator to press from the pressing hole 5. The other end of the rocker arm 13 has a top rod 14. When the top rod 14 is pressed, it lifts the manhole cover 3 from the bottom. By repeatedly pressing the rocker arm 13 with the pressing rod 6, the top rod 14 is repeatedly lifted upward, making the manhole cover 3 loose and easy to open.

[0016] The top of the manhole cover 3 is provided with a drainage hole 4.

[0017] The pressing hole 5 is equipped with a pressing rod 6 for the operator to use, and the pressing rod 6 can be inserted into the pressing hole 5.

[0018] The top of the pressing rod 6 is covered with a rubber anti-slip pad.

[0019] The inner wall of the mounting ring 1 is provided with a groove that is recessed downward from the top of the placement groove 2. The connecting rod 9 is placed in the groove. After opening the well cover 3, the connecting block 8 and the connecting rod 9 can also be taken out.

[0020] The method of using this utility model is briefly described as follows:

[0021] When the manhole cover 3 is not easy to open, the pressing rod 5 is inserted along the pressing hole 5 and the rocker arm 13 is repeatedly struck, so that the top 14 on the other end of the rocker arm 13 strikes the manhole cover 3, thereby loosening the manhole cover and making it easier for the operator to lift the manhole cover 3. When the staff needs to go down into the underground pipeline through the manhole cover to work, the connecting block 8 and the connecting rod 9 can also be taken out from the slot.
