Description

Technical Field

[0001] The utility model belongs to the technical field of manhole covers, and in particular relates to a high-stability composite manhole cover. Background Art

[0002] Patent application number 202321635163.8 discloses a multifunctional municipal composite manhole cover, including a composite manhole cover, a manhole seat, a drainage hole and a block, etc. Through the structural design of the block, the rotating seat, the rotating block, the first handle and other structures, the rotating block is driven to rotate on the rotating seat by rotating the first handle, and the rotating block drives the block to rotate, so as to adjust the size of the drainage hole, prevent the drainage hole from being blocked by garbage, and avoid danger caused by water accumulation on the road.

[0003] The adjustment of the drainage holes on the composite manhole cover should be uniformly adjusted and controlled by municipal personnel according to weather conditions. Although the above-mentioned disclosed technical solution can achieve the adjustment of the size of the drainage holes, its adjustment method is relatively arbitrary and anyone can directly operate it, such as pulling the rotating block to rotate or moving the block, etc., which can change the size of the drainage hole. After the municipal personnel make adjustments, the drainage holes are maliciously damaged again. For example, when it rains, the municipal personnel enlarge the opening of the drainage hole, and then other personnel maliciously reduce it, causing the rainwater to carry garbage and still block the smaller drainage hole.

[0004] In order to improve the stability of the drainage hole after adjustment, a high-stability composite manhole cover is proposed, which aims to prevent the drainage hole from being maliciously damaged by other personnel after the size of the drainage hole is adjusted. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a high-stability composite manhole cover. The drain hole can only be adjusted by carrying a card block. Other personnel do not have the card block and cannot maliciously adjust the size of the drain hole. After the municipal personnel adjust the drain hole, the size of the drain hole is fixed and is not easily damaged by other personnel, thereby improving the stability of the drain hole after adjustment and preventing it from being maliciously damaged by other personnel.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The top of the fixing plate is connected with the fixing plate of the fixing plate, and the fixing plate has the fixing structure that the fixing plate is connected with the fixing plate.

[0008] Furthermore, there are several limiting grooves, and the limiting grooves are distributed in a circle.

[0009] Furthermore, the shape of the card slot is a straight slot, a cross slot or a plum blossom slot.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. By rotating the block, the slide groove, the spring, the slide rod and the limit plate, when cooperating with the card slot and the card block, the drain hole can be adjusted by carrying the card block. Other personnel do not have the card block and cannot maliciously adjust the size of the drain hole. When cooperating with the limit groove and the limit block, the size of the drain hole can be fixed after the municipal personnel adjust the drain hole, and it is not easy for other personnel to damage it, thereby improving the stability of the drain hole after adjustment and preventing it from being maliciously damaged by other personnel.

[0012] 2. A large number of limit grooves distributed around the circumference can make it easier for the limit grooves to correspond to the limit blocks after the limit plate rotates. By designing slots of different shapes, municipal personnel only need to use the corresponding blocks to adjust the drainage holes, while other personnel lack the corresponding tools, which increases the difficulty of damage and further avoids malicious damage.

Example

[0020] See attached Figure 1-4 As shown, a high-stability composite manhole cover comprises a composite manhole cover 1, a drainage hole 2 is provided on the upper surface of the composite manhole cover 1, a stopper 3 is slidably provided in the drainage hole 2, a connecting rod 4 is fixedly connected to the side wall of the stopper 3, a mounting groove 5 is provided inside the composite manhole cover 1, a rotating block 6 is rotatably connected to the bottom of the mounting groove 5, an end of the connecting rod 4 away from the stopper 3 is fixedly connected to the rotating block 6, two symmetrical sliding grooves 7 are provided on the upper surface of the rotating block 6, a spring 8 is fixedly connected to the bottom of the sliding groove 7, and a spring 8 is fixedly connected to the top of the spring 8. The slide groove 7 is slidably connected to the slide rod 9, and the top ends of the two slide rods 9 are commonly fixedly connected to the limit plate 10. The upper surface of the limit plate 10 is provided with a limit groove 11, and the top of the mounting groove 5 is fixedly connected with a limit block 12 corresponding to the limit groove 11. A card slot 13 is provided in the middle of the upper surface of the limit plate 10, and a matching card block 14 is inserted in the card slot 13. The top of the card block 14 is fixedly connected with a fixing rod 15, and the top of the mounting groove 5 is provided with a through hole 16. The top end of the fixing rod 15 passes through the through hole 16 and is fixedly connected with a handle 17.

[0021] There are several limiting grooves 11 , and the limiting grooves 11 are distributed in a circle.

[0022] The shape of the slot 13 is a straight slot, a cross slot or a plum blossom slot.

[0023] Working principle: In the present utility model, taking the card slot 13 as a straight slot as an example, the municipal staff holds the handle 17, lifts the straight card block 14 through the fixed rod 15, and inserts the card block 14 downward into the card slot 13 through the through hole 16. The municipal staff presses down the handle 17, and then the card block 14 presses down the limit plate 10. At this time, the slide bar 9 moves synchronously with the limit plate 10, squeezing the spring 8 in the slide slot 7 until the limit block 12 is separated from the limit slot 11, and then the handle 17 is rotated, and then the card block 14 is in the card slot 13, driving the limit plate 10 to rotate synchronously, and the rotating block 6 is rotated with the limit plate 10 through the two slide bars 9, and the connecting rod 4 is used to The stopper 3 moves with the rotating block 6, and when the municipal personnel rotate the handle 17, the stopper 3 moves at the drain hole 2 to adjust the size of the drain hole 2. After the adjustment is completed, lift the handle 17 to store the block 14, and the spring 8 pushes the slide bar 9 to reset upward, and the slide bar 9 pushes the limit plate 10 until the limit plate 10 is pushed to the top of the installation groove 5. At this time, the limit block 12 is re-located in the limit groove 11 to prevent the limit plate 10 from rotating, and then the rotating block 6 cannot rotate with the limit plate 10, so that the stopper 3 cannot move. When other personnel buckle the stopper 3 with their hands, the stopper 3 cannot move, and it is not easy to change the size of the drain hole 2.
