Description

Technical Field

[0001] The utility model relates to the technical field of gardening, in particular to a garden manhole cover which is easy to open. Background Art

[0002] Decorative covers play an important role in landscape and municipal roads. They are used to decorate various pipe covers on community square roads, so that they can be integrated with adjacent pavements and increase their aesthetics. However, in actual use, during inspection and maintenance, they are relatively heavy and often require two people to open them at the same time. The pavement on the decorative cover is usually related to the overall pavement. After the inspection is completed, the workers do not realize that the decorative cover needs to be placed according to the original pavement, resulting in the cover being replaced and the surrounding pavement being inconsistent and affecting the appearance. In addition, during heavy rains, the cover may be pushed open, causing pedestrians to fall in. Summary of the invention

[0003] The utility model overcomes the deficiencies of the prior art and provides a garden manhole cover that is easy to open and can be opened by one person. After inspection and replacement, it can be consistent with the original paving, reducing labor expenditure costs, ensuring the original overall paving form is beautiful, and can prevent it from being pushed open by rainwater, thereby increasing its safety in use.

[0004] In order to achieve the above purpose, a garden manhole cover that is easy to open is designed, including a metal base. A metal tray is provided above the metal base. Telescopic spring cylinders are respectively connected to the four corners of the metal base. The upper end of one of the telescopic spring cylinders is fixedly connected to the metal tray. One end of a locking bolt is connected to the metal base, and the other end of the locking bolt passes through the upper end of the metal tray and is provided with a key slot.

[0005] The lower end of the metal tray is connected to a universal pulley, and a height difference is arranged between the lower end of the universal pulley and the metal base.

[0006] The height of the universal pulley is consistent with the height of the telescopic spring tube after it is bounced up.

[0007] The upper end of the metal tray is connected to the paving layer through an adhesive layer.

[0008] A plurality of reinforcing ribs are arranged inside the metal tray.

[0009] The structure of the metal base is a rectangular structure.

[0010] The locking bolt has an L-shaped structure.

[0011] The four corners of the metal base are provided with mounting holes for mounting the telescopic spring tube.

[0012] Compared with the prior art, the utility model adopts the combination of telescopic spring tube, metal tray and locking bolt, so that one person can easily open the cover plate; at the same time, the cover plate is restored to its original position to ensure the beautiful paving; in addition, it can prevent the cover plate from being pushed open by rainwater in heavy rain, thus ensuring safety.

[0020] The utility model is further described below with reference to the accompanying drawings. Example

[0021] like Figures 1 to 5 As shown, a metal tray 2 is provided above the metal base 1, and telescopic spring tubes 3 are connected to the four corners of the metal base 1, and the upper end of one of the telescopic spring tubes 3 is fixedly connected to the metal tray 2. One end of the locking bolt 5 is connected to the metal base 1, and the other end of the locking bolt 5 passes through the upper end of the metal tray 2 and is provided with a key slot to prevent it from being opened at will. The outer side of the locking bolt 5 is treated with rust prevention or made of stainless steel. When used specifically, Figure 6 to Figure 7 As shown, the locking bolt is opened by means of a key 6 which fits into a key slot.

[0022] The lower end of the metal tray 2 is connected to the universal pulley 4 , and a height difference is provided between the lower end of the universal pulley 4 and the metal base 1 to ensure that the universal pulley 4 does not contact the metal base 1 .

[0023] The height of the universal pulley 4 is consistent with the height of the telescopic spring tube 3 after it is bounced up.

[0024] The upper end of the metal tray 2 is connected to the paving layer 7 through an adhesive layer 8. A plurality of reinforcing ribs 9 are provided inside the metal tray 2 to increase the strength of the metal tray 2 and prevent the paving layer 7 from breaking.

[0025] The metal base 1 is a rectangular structure. The four corners of the metal base are provided with mounting holes for mounting the telescopic spring tube 3, so as to ensure that the telescopic spring tube 3 is flush with the upper end of the metal base 1 after being compressed.

[0026] The locking bolt 5 has an L-shaped structure.

[0027] When this embodiment is used, there are two locking bolts 5 , which are respectively located on the left and right sides of the metal base 1 .

[0028] When the utility model is installed, the metal cover plate 1 is fixed to the pre-buried civil engineering metal parts at the edge of the wellhead. When the wellhead cover is in a closed state, Figure 3 As shown in the figure, the locking bolt 5 is locked, the telescopic spring tube 3 is in a compressed state, and the paving layer 7 is on the same plane as the surrounding paving. At this time, the staff standing on it inserts the special opening key 6 into the key slot of the locking bolt 5 and rotates it forcefully to open the manhole cover. Figure 4 As shown in the figure, the manhole cover is in the open state and still on the top of the manhole. At this time, the locking bolt 5 is in the open state and the spring tube 3 is in the pop-up state. At this time, the metal tray 2 is moved away from the top of the manhole by rotating the telescopic spring tube 3 fixedly connected to the metal tray 2. Figure 5 As shown, at this time, the entire metal tray 2 is supported by the telescopic spring tube 3 and the universal pulley 4.
