Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water tank cover technology, and in particular relates to a V-shaped water tank cover structure. Background Technology
[0002] Most radiator caps have pressure relief holes, whose main function is to maintain the cooling system pressure within a reasonable range and protect the cooling system components from excessive pressure. When the pressure in the cooling system rises to a certain level and exceeds the pressure value set on the radiator cap, the valve on the pressure relief hole will be opened, allowing some coolant vapor or high-pressure coolant to be discharged through the pressure relief hole, thereby reducing the pressure in the system. When the pressure drops to a certain level, the valve will automatically close to prevent the coolant from continuing to flow out.
[0003] When a water tank operates for a long time or ages, its internal temperature becomes high. If the pressure relief cover is lifted using the existing pressure, it may not be able to release pressure in time. Therefore, when maintenance is required, the pressure relief speed needs to be accelerated to ensure the normal use of the water tank and to address the shortcomings of the existing technology. Utility Model Content
[0004] The purpose of this invention is to provide a V-shaped water tank cover structure that accelerates the pressure relief speed and ensures the normal use of the water tank, thereby solving the aforementioned technical problems.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A V-shaped water tank cover structure includes an end cover threadedly connected to the inner cavity of a liquid pipe. The bottom of the liquid pipe is connected to a water tank body. A pressure relief cylinder is fixedly connected to the axial center of the inner cavity of the end cover. A spring is fixedly connected to the bottom of the inner cavity of the end cover and inside the pressure relief cylinder. A pressure relief cover is fixedly connected to the top of the spring. A column is fixedly connected to the axial center of the pressure relief cover. A connecting plate is fixedly connected to the top of the surface of the pressure relief cylinder. A threaded rotating rod is rotatably connected to the top of the inner cavity of the connecting plate. A gear is fixedly sleeved on the surface of the threaded rotating rod. A rack is fixedly connected to the surface of the column. The rack meshes with the surface of the gear. A limit nut is threadedly connected to the outer surface of the connecting plate through the threaded rotating rod.
[0006] Preferably, a pressure relief hole is provided at the center of the end cap, the pressure relief hole extends through the interior of the pressure relief cylinder, and the spring is located at the outer ring of the through hole.
[0007] Preferably, the top end face of the end cap has a concave design.
[0008] Preferably, a limiting post is fixedly connected at the center of the bottom of the pressure relief cover, and the limiting post is located in the inner ring of the spring.
[0009] Preferably, a rubber sleeve is fixedly fitted onto the outer surface of the pressure relief cover, and the outer surface of the rubber sleeve is slidably connected to the inner surface of the pressure relief cylinder.
[0010] The beneficial effects of this utility model are:
[0011] 1. When this utility model requires periodic maintenance, simply rotate the limiting nut to rotate the threaded rod surface, thereby releasing the limiting nut. Then rotate the threaded rod, causing the gear to rotate. The rotation of the gear drives the rack to move, which in turn moves the column and causes the pressure relief cover to slide on the inner surface of the pressure relief cylinder. This pulls the spring to stretch and limit the pressure relief, thereby increasing the distance between the spring and the pressure relief cylinder. The limiting nut is then used to fasten the threaded connection to the surface of the threaded rod. By setting the above structure, the pressure relief speed is accelerated, ensuring the normal use of the water tank.
[0012] 2. This utility model, by setting a pressure relief hole, allows pressure to be released by pushing up the pressure relief cover through the pressure relief hole;
[0013] 3. This utility model limits the position of the spring by setting a limiting post in the inner ring of the spring, thus preventing displacement.
[0014] 4. This utility model has a rubber sleeve fixedly attached to the outer surface of the pressure relief cover, which can fill the space between the pressure relief cover and the inner surface of the pressure relief cylinder, reducing the entry of external gas. Attached Figure Description

[0022] In the following description, embodiments of the V-shaped water tank cover structure of this utility model will be described with reference to the accompanying drawings.
[0023] Example 1:
[0024] Figure 1-4 This invention illustrates a V-shaped water tank cover structure according to an embodiment of the present invention, including an end cap 3 threadedly connected to the inner cavity of a liquid pipe 2. The bottom of the liquid pipe 2 is connected to a water tank body 1. A pressure relief cylinder 4 is fixedly connected to the axial center of the inner cavity of the end cap 3. A pressure relief hole is provided at the axial center of the end cap 3, penetrating the interior of the pressure relief cylinder 4. A spring 5 is located at the outer ring of the through hole. The top end face of the end cap 3 has a concave design. A spring 5 is fixedly connected to the bottom of the inner cavity of the end cap 3, located inside the pressure relief cylinder 4. A pressure relief cover 6 is fixedly connected to the top of the spring 5. By providing a pressure relief hole, pressure is released by pushing up the pressure relief cover 6 through the pressure relief hole. A column 7 is fixedly connected to the axial center of the pressure relief cover 6. A connecting plate 8 is fixedly connected to the top of the surface of the pressure relief cylinder 4. A threaded rotating rod 9 is rotatably connected to the top of the inner cavity of the connecting plate 8. A threaded rotating rod 9 is fixedly sleeved on the surface of the threaded rotating rod 9. Gear 10 and rack 11 are fixedly connected to the surface of column 7. The rack 11 meshes with the surface of gear 10. Threaded rod 9 passes through the outer surface of connecting plate 8 and is threadedly connected to limit nut 12. When periodic maintenance is required, simply rotate the limit nut 12, causing the threaded rod 9 to rotate threadedly, thus releasing the limit nut 12. Then, rotate the threaded rod 9, causing gear 10 to rotate. The rotation of gear 10 drives rack 11 to move, thereby moving column 7 and causing pressure relief cover 6 to slide on the inner surface of pressure relief cylinder 4. This pulls spring 5 to stretch and limit its position, thus widening the gap between spring 5 and pressure relief cylinder 4. The limit nut 12 is then used to secure the threaded connection to the surface of threaded rod 9. By setting up the above structure, the pressure relief speed is accelerated, ensuring the normal use of the water tank.
[0025] Example 2:
[0026] Figure 1-4This invention illustrates a V-shaped water tank cover structure according to an embodiment of the present invention, including an end cap 3 threadedly connected to the inner cavity of a liquid pipe 2. The bottom of the liquid pipe 2 is connected to a water tank body 1. A pressure relief cylinder 4 is fixedly connected to the axial center of the inner cavity of the end cap 3. A spring 5 is fixedly connected to the bottom of the inner cavity of the end cap 3 and inside the pressure relief cylinder 4. A pressure relief cover 6 is fixedly connected to the top of the spring 5. A limiting post 13 is fixedly connected to the axial center of the bottom of the pressure relief cover 6. The limiting post 13 is located within the inner ring of the spring 5. A rubber sleeve 14 is fixedly fitted onto the outer surface of the pressure relief cover 6. The outer surface of the rubber sleeve 14 is slidably connected to the inner surface of the pressure relief cylinder 4. By setting the limiting post 13 to be located within the inner ring of the spring 5, the pressure relief cover 6 can be... The position of the spring 5 is limited to prevent displacement. A rubber sleeve 14 is fixedly fitted to the outer surface of the pressure relief cover 6 to fill the space between the pressure relief cover 6 and the inner surface of the pressure relief cylinder 4, reducing the entry of external gas. A column 7 is fixedly connected to the axis of the pressure relief cover 6. A connecting plate 8 is fixedly connected to the top of the surface of the pressure relief cylinder 4. A threaded rod 9 is rotatably connected to the top of the inner cavity of the connecting plate 8. A gear 10 is fixedly fitted to the surface of the threaded rod 9. A rack 11 is fixedly connected to the surface of the column 7. The rack 11 meshes with the surface of the gear 10. A limit nut 12 is threaded through the outer surface of the connecting plate 8.
[0027] Working principle: When this utility model is in use and periodic maintenance is required, simply rotate the limiting nut 12. The threaded rotating rod 9 rotates on the surface of the threaded rod, releasing the limiting nut 12. Then, rotate the threaded rotating rod 9, causing the gear 10 to rotate. The rotation of the gear 10 drives the rack 11 to move, thereby moving the column 7 and causing the pressure relief cover 6 to slide on the inner surface of the pressure relief cylinder 4. This pulls the spring 5 to stretch and limit its position, thereby increasing the distance between the spring 5 and the pressure relief cylinder 4. The limiting nut 12 is then used to tighten the threaded connection to the surface of the threaded rotating rod 9, thus accelerating the pressure relief speed and ensuring the normal use of the water tank.
