Description

Technical Field

[0001] This utility model relates to the field of insect-proof cover technology, and in particular to an overflow pipe insect-proof cover. Background Technology

[0002] A pipe is generally a device used to maintain a certain liquid level and quickly drain excess liquid. It is often used in devices such as solar water heaters and water tanks that require timely water level monitoring. Containers such as water heaters and water tanks usually have pipe openings to maintain a certain liquid level. The cross-section of the pipe opening must be sufficient so that excess liquid can be quickly overflowed and drained when the liquid level exceeds the limit. However, the opening of a traditional pipe is open, which allows various insects to easily fly into the pipe and then into the water tank, thus affecting the water quality. Utility Model Content

[0003] Therefore, it is necessary to provide an insect-proof cover for the overflow pipe, which addresses the issue that the opening of the traditional pipe is open, allowing various insects to easily fly into the pipe and then into the water tank, thus affecting the water quality.

[0004] An overflow pipe insect-proof cover includes a pipe body, an insect-proof cover, a rotating shaft, a pressure block, and an insect-proof net. The pipe body has an outlet, and the rotating shaft is horizontally positioned at the middle of the outlet of the pipe body, dividing the outlet into a first outlet and a second outlet. The insect-proof net is disposed on the first outlet, and the insect-proof cover is rotatably mounted on the rotating shaft. When the insect-proof cover is in a horizontal position, one side of the insect-proof cover covers the insect-proof net, and the other side of the insect-proof cover covers the second outlet. The pipe body is provided with a limiting component to restrict the rotation of the insect-proof cover from exceeding 90 degrees. The pressure block is disposed on the side of the insect-proof cover that covers the insect-proof net. A fastening component is provided at the end of the pipe body away from the outlet.

[0005] In one embodiment, a first bearing and a second bearing are provided on the same horizontal plane of the tube body, and the two ends of the rotating shaft are respectively provided on the first bearing and the second bearing.

[0006] In one embodiment, the limiting component is a limiting block, the first bearing is provided with an inner ring and an outer ring, the outer ring is disposed on the tube body, the inner ring is disposed inside the outer ring, the rotating shaft is rotatably disposed on the inner ring, and one end of the rotating shaft is disposed on the inner ring and extends out of the inner ring, and the limiting block is disposed on the side of the first bearing away from the center of the tube body.

[0007] In one embodiment, a locking block is provided at one end of the rotating shaft extending outside the inner ring. When the rotating shaft drives the insect-proof cover to rotate to ninety degrees, the locking block abuts against the limiting block.

[0008] In one embodiment, the horizontal cross-section of the insect-proof cover is smaller than the horizontal cross-section of the outlet.

[0009] In one embodiment, the horizontal cross-section of the outlet of the tube and the horizontal cross-section of the insect-proof cover are both circular.

[0010] The aforementioned overflow pipe insect cover includes a pipe body, an insect cover, a rotating shaft, a pressure block, and an insect screen. The pipe body has an outlet. The rotating shaft is horizontally rotatable and positioned at the middle of the outlet, dividing the outlet into a first outlet and a second outlet. The insect screen is positioned on the first outlet. The insect cover is rotatably mounted on the rotating shaft. When the insect cover is in a horizontal position, one side of the cover covers the insect screen, and the other side covers the second outlet. The rotating shaft is equipped with a limiting component to prevent the insect cover from rotating more than 90 degrees. The pressure block is positioned on the side of the cover that is covering the insect screen. A fastening component is located at the end of the pipe body away from the outlet, which secures the insect cover to the overflow pipe. The rotating shaft is horizontally rotatable and positioned on the pipe body. At the center of the outlet, the insect-proof cover is rotatably mounted on a rotating shaft. A limiting component on the pipe body restricts the insect-proof cover from rotating more than 90 degrees. A pressure block is positioned on the side where the insect-proof cover closes to the insect-proof net, ensuring the cover is horizontal when no water overflows from the pipe. One side of the insect-proof cover closes to the insect-proof net, and the other side closes to the second outlet, preventing insects from entering the pipe. When water flows out of the pipe, the water flow impacts the insect-proof cover, causing it to flip towards the second outlet. The limiting component restricts the cover's rotation, ensuring it only rotates to a vertical position at most, preventing excessive rotation that could block the second outlet. This effectively prevents insects from entering the pipe while also allowing water to drain efficiently. Attached Figure Description

[0014] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0015] like Figures 1-3 As shown, an overflow pipe insect cover includes a pipe body 10, an insect cover 20, a rotating shaft 30, a pressure block 40, and an insect screen 50. The pipe body 10 is provided with an outlet 110. The rotating shaft 30 is horizontally positioned in the middle of the outlet 110 of the pipe body 10, dividing the outlet 110 into a first outlet 111 and a second outlet 112. The insect screen 50 is disposed on the first outlet 111. The insect cover 20 is rotatably disposed on the rotating shaft 30. When the insect cover 20 is in a horizontal position, one side of the insect cover 20 covers the insect screen 50, and the other side of the insect cover 20 covers the second outlet 112. The pipe body 10 is provided with a limiting component 130 for limiting the rotation of the insect cover 20 to more than 90 degrees. The pressure block 40 is disposed on the side of the insect cover 20 that covers the insect screen 50. For example, by setting a pressure block 40 inside the side of the insect cover 20 that covers the insect net 50, the insect cover 20 can cover the insect net 50 and the second outlet 112 in a natural state where no water flows out of the pipe body 10. A fastening component 120 is provided at the end of the pipe body 10 away from the outlet 110. By setting the fastening component 120, the pipe body 10 can be fixed to the pipe opening on the overflow pipe. The fastening component 120 can be a hose clamp. When the pipe body 10 is connected to the overflow pipe, half of the hose clamp is fixed to the pipe body 10, and the other half of the hose clamp is used to fasten the overflow pipe. Fixing with a hose clamp is a common technique in the field of water pipe fastening, and will not be described in detail here.

[0016] In one embodiment, a first bearing 60 and a second bearing (not shown) are provided on the same horizontal plane of the tube body 10, and the two ends of the rotating shaft 30 are respectively provided on the first bearing 60 and the second bearing. For example, a first mounting hole (not shown) and a second mounting hole (not shown) are respectively provided on both sides of the tube body 10, the first bearing 60 is provided on the first mounting hole, and the second bearing is provided on the second mounting hole.

[0017] In one embodiment, the limiting component 130 is a limiting block 130. The first bearing 60 is provided with an inner ring 610 and an outer ring 620. The outer ring 620 is disposed on the tube body 10, and the inner ring 610 is disposed inside the outer ring 620. The rotating shaft 30 is rotatably disposed on the inner ring 610, and one end of the rotating shaft 30 extends out of the inner ring 610. The limiting block 130 is disposed on the side of the first bearing 60 away from the center of the tube body 10. For example, a ball bearing layer (not shown) is also provided between the inner ring 610 and the outer ring 620. Sealing rings 630 are provided on both sides of the ball bearing layer. The sealing rings 630 and the ball bearing layer are in clearance fit. The smaller the clearance between the sealing rings 630 and the ball bearing layer, the better, as long as the sealing rings 630 and the inner ring 610 fit together without affecting the rotation of the inner ring 610. By providing sealing rings 630 on both sides of the ball bearing layer, insects can be prevented from entering the tube body 10 from the ball bearing layer.

[0018] In one embodiment, a locking block 310 is provided at one end of the rotating shaft 30 extending outside the inner ring 610. When the rotating shaft 30 drives the insect-proof cover 20 to rotate to ninety degrees, the locking block 310 abuts against the limiting block 130. For example, by the locking block 310 abutting against the limiting block 130, the limiting block 130 can restrict the side of the insect-proof cover 20 that is closed on the insect-proof net 50 from rotating to the second outlet 112, thereby blocking the second outlet 112.

[0019] In one embodiment, the horizontal cross-section of the insect-proof cover 20 is smaller than the horizontal cross-section of the outlet 110. For example, the horizontal cross-section of the insect-proof cover 20 is smaller than the horizontal cross-section of the outlet 110, and the specific size is set according to the horizontal cross-section of the outlet 110. This ensures that the insect-proof cover 20 can be placed inside the inlet / outlet 110 in a horizontal state, and also prevents insects from entering the pipe body 10 when the insect-proof cover 20 is in a horizontal state.

[0020] In one embodiment, the horizontal cross-section of the outlet 110 of the tube 10 and the horizontal cross-section of the insect-proof cover 20 are both circular. For example, the circular cross-section of the outlet 110 of the tube 10 and the horizontal cross-section of the insect-proof cover 20 facilitates the rotation of the insect-proof cover 20 within the tube 10.

[0021] The aforementioned overflow pipe insect cover includes a pipe body 10, an insect cover 20, a rotating shaft 30, a pressure block 40, and an insect screen 50. The pipe body 10 is provided with an outlet 110. The rotating shaft 30 is horizontally rotatably positioned at the middle of the outlet 110 of the pipe body 10, dividing the outlet 110 into a first outlet 111 and a second outlet 112. The insect screen 50 is disposed on the first outlet 111. The insect cover 20 is rotatably disposed on the rotating shaft 30. When the insect cover 20 is in a horizontal position... At this time, one side of the insect-proof cover 20 covers the insect-proof net 50, and the other side of the insect-proof cover 20 covers the second outlet 112. A limiting component 130 is provided on the rotating shaft 30 to limit the rotation of the insect-proof cover 20 beyond 90 degrees. A pressure block 40 is provided on the side of the insect-proof cover 20 that covers the insect-proof net 50. A fastening component 120 is provided at the end of the pipe body 10 away from the outlet 110. By providing the fastening component 120, the pipe body 10 can be fixed to the overflow pipe. At the pipe opening, a rotating shaft 30 is horizontally rotatably positioned in the middle of the outlet 110 of the pipe body 10. An insect-proof cover 20 is rotatably mounted on the rotating shaft 30. A limiting component 130 is provided on the rotating shaft 30 to restrict the insect-proof cover 20 from rotating more than 90 degrees. A pressure block 40 is positioned on one side of the insect-proof cover 20 covering the insect-proof net 50, ensuring that the insect-proof cover 20 is in a horizontal position when no water overflows from the pipe body 10, with both sides of the insect-proof cover 20 precisely covering one side of the insect-proof net 50. The other side is covered to the second outlet 112, preventing insects from entering the pipe body 10. When water flows out of the pipe body 10, the water flow impacts the insect-proof cover 20, causing the insect-proof cover 20 to flip towards the second outlet 112. The limiting component 130 restricts the insect-proof cover 20, allowing it to rotate to a vertical position at most, preventing the insect-proof cover 20 from rotating too much and blocking the second outlet 112. This not only prevents insects from entering the pipe body 10, but also allows the water in the pipe body 10 to be effectively discharged.

[0022] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0023] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
