Description

Technical Field

[0001] This utility model relates to the field of water meter technology, and in particular to a highly sealed sewage-saving water meter cover. Background Technology

[0002] In the prior art, such as the high-sensitivity anti-backflow water meter published on the Chinese patent website with announcement number CN 216116191 U, the cover plate is rotated by flipping it, and the cover plate drives the connecting block to rotate. At the same time, the connecting plate and the cover plate are flipped, and the connecting plate and the bearing are connected and moved, which reduces friction and increases the service life of the cover plate.

[0003] However, as the main component protecting the watch body, most of the existing cover plates are made of plastic. When buried underground in a dark room for a long time, they are easily damaged by gravel or even the soil on top. If they are replaced with metal plates, the metal is also prone to corrosion and rust. Moreover, a simple metal cover plate is too hard and is easily flattened when gravel falls and hits it. Utility Model Content

[0004] Based on existing technical problems, this utility model proposes a highly sealed sewage discharge and water-saving meter cover.

[0005] The present invention proposes a highly sealed sewage discharge and water-saving meter cover, which includes a cover plate that is movably hinged to the top side of the meter body.

[0006] A sealing structure is provided at the contact position between the lower surface of the cover plate and the upper surface of the watch body. When the cover plate is hinged and pressed against the upper surface of the watch body, it seals the inside of the watch body.

[0007] After the cover plate has a cavity inside, a buffer mechanism is installed. When the cover plate is impacted or hit, the buffer mechanism forms a circle to resist the impact.

[0008] Preferably, the sealing mechanism includes a sealing ring that is movably fitted onto the upper surface of the cover body, and a rubber sleeve is fixedly installed on the inner top wall of the cover plate.

[0009] When the cover plate covers the watch body, the rubber sleeve presses against the sealing ring to achieve a sealing action.

[0010] The above technical solution can seal and protect the inside of the watch body, preventing stains or impurities in sewage from entering the watch body.

[0011] Preferably, the buffer mechanism includes a spring plate embedded in the cover plate, the surface of the spring plate being arc-shaped, and when multiple spring plates are joined end to end, they form a complete circle.

[0012] The above technical solution embeds the spring plate inside the cover plate, and the cover plate wraps around the spring plate to prevent rusting.

[0013] Preferably, the spring plate has a vortex hole inside, and a vortex spring is movably sleeved inside the vortex hole.

[0014] Through the above technical solutions, the spiral spring can further increase the buffering force of the spring plate.

[0015] Preferably, the surface of the spring plate is provided with a buffer groove. When the cover plate is impacted, the inner walls on both sides of the buffer groove come into close contact and are elastically squeezed to achieve elastic buffering.

[0016] The above technical solution can provide the necessary compression space for the spring plate during cushioning.

[0017] Preferably, a stress-resistant groove is also provided at one bottom end of the buffer groove. When the inner walls on both sides of the buffer groove are pressed together, the opening of the stress-resistant groove elastically opens and closes towards the middle.

[0018] The above technical solution can prevent the spring plate from cracking due to stress.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By setting a sealing structure, the upper surface of the watch body can be effectively sealed to prevent external humidity, dust, or gravel from entering the watch body and damaging it.

[0021] 2. By setting up a buffer mechanism, the cover plate of the plastic part can be effectively embedded in the buffer structure, thereby effectively enhancing the strength and buffer resistance of the cover plate and protecting the internal structure of the watch body from damage.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-5 A high-sealing sewage-saving water meter cover includes a cover plate 2 that is movably hinged to the top side of the meter body 1.

[0030] In order to provide waterproof protection for the internal structure of the watch body 1, a sealing structure is provided at the contact position between the lower surface of the cover plate 2 and the upper surface of the watch body 1. When the cover plate 2 is hinged and pressed against the upper surface of the watch body 1, the interior of the watch body 1 is sealed.

[0031] The sealing is achieved as follows: the sealing mechanism includes a sealing ring 21 that is movably sleeved on the upper surface of the body 1, and a rubber sleeve 22 is fixedly installed on the inner top wall of the cover plate 2.

[0032] When the cover plate 2 covers the meter body 1, the rubber sleeve 22 presses against the sealing ring 21 to achieve a sealing action. This can seal and protect the inside of the meter body 1, preventing stains or impurities in sewage from entering the meter body 1.

[0033] By setting a sealing structure, the upper surface of the watch body 1 can be effectively sealed to prevent external humidity, dust, or gravel from entering the watch body 1 and damaging it.

[0034] To enhance the cushioning effect of the cover plate 2, a cushioning mechanism is installed after a cavity is created inside the cover plate 2. When the cover plate 2 is subjected to impact or collision, the cushioning mechanism forms a complete circle to achieve impact resistance. Simultaneously, to enhance the overall strength of the cover plate 2, reinforcing ribs 23 can be fixedly installed on the back of the cover plate 2 to increase overall strength.

[0035] The buffering mechanism is implemented as follows: The buffer mechanism includes a spring plate 3 embedded within the cover plate 2. The surface of the spring plate 3 is arc-shaped, and when multiple spring plates 3 are joined end-to-end, they form a complete circle. The spring plate 3 is embedded within the cover plate 2, which encloses it to prevent rusting.

[0036] To further enhance the cushioning effect, a vortex hole is provided inside the spring plate 3, and a vortex spring 31 is movably sleeved inside the vortex hole. The vortex spring 31 can further increase the cushioning force of the spring plate 3.

[0037] To provide the necessary space for the spring plate 3 to cushion the impact, a buffer groove 32 is provided on the surface of the spring plate 3. When the cover plate 2 is impacted, the inner walls on both sides of the buffer groove 32 come into close contact and are elastically compressed, thus achieving an elastic cushioning action. This provides the necessary compression space for the spring plate 3 to cushion the impact.

[0038] Furthermore, a stress-resistant groove 33 is also provided at one bottom end of the buffer groove 32. When the inner walls on both sides of the buffer groove 32 are pressed together, the opening of the stress-resistant groove 33 elastically opens and closes towards the middle. This can prevent the spring plate 3 from cracking due to stress.

[0039] By setting a buffer mechanism, the cover plate 2 of the plastic part can be effectively embedded into the buffer structure, thereby effectively enhancing the strength and buffer resistance of the cover plate 2 and protecting the internal structure of the watch body 1 from damage.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
