Abstract
Description
Technical Field
[0001] This utility model relates to the field of water meter technology, specifically to a rotary anti-drip water meter. Background Technology
[0002] Rotary vane water meters are products used for measuring the total unidirectional water flow in small-diameter pipes. They come in wet and dry types and are widely used in households for accurate water consumption. However, most existing rotary vane water meters connect to external water pipes via threaded connections. Therefore, even slight discrepancies in the dimensions of the external and internal threads can easily cause water to overflow through the gaps between them. Over time, this leads to continuous water waste. Because of this waste, the rotary vane water meter slowly measures the wasted water, directly causing economic losses for residents.

[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a rotary anti-drip water meter, which has the following beneficial effects:
[0015] 1. This rotary vane anti-drip water meter, through its external thread, allows for threaded connections of the inlet and outlet pipes to two sets of external water pipes. The sleeve is then moved outwards until the inner wall of the seal is tightly against the connection points between the inlet and outlet pipes and the two sets of external water pipes. A spring then drives a locking block into the slot, securing the sleeve. The presence of the seal increases the sealing at the connections between the inlet and outlet pipes and the two sets of external water pipes, preventing water from overflowing through gaps. Therefore, it prevents continuous water waste and avoids the situation where leakage at the connection points causes the rotary vane water meter to slowly measure the wasted water, thus preventing direct economic losses for residents.
[0016] 2. This rotary anti-drip water meter uses the reaction force generated by the compression of the return spring to continuously compress the moving block outward, which makes the locking block firmly inserted into the slot, ensuring the stability of the sleeve being locked and indirectly improving the sealing effect of the sealing element.
[0017] 3. This rotary anti-drip water meter uses a limiting block that slides along the inside of the limiting groove to limit the movement of the sleeve. This prevents the sleeve from rotating when the operator moves it, thus preventing the slot from aligning with the block and improving the practicality of the device. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 This utility model provides a technical solution: a rotary vane anti-drip water meter, including a rotary vane water meter body 1. The rotary vane water meter body 1 includes an inlet pipe 101, an outlet pipe 102, an external thread 103, and an instrument body 104. The left and right sides of the outer surface of the rotary vane water meter body 1 are respectively connected to the inlet pipe 101 and the outlet pipe 102. The outer sides of the outer surfaces of the inlet pipe 101 and the outlet pipe 102 are provided with external threads 103. The upper surface of the rotary vane water meter body 1 is provided with the instrument body 104. Because the rotary vane water meter body 1 includes the inlet pipe 101, the outlet pipe 102, the external thread 103, and the instrument body 104, and the rotary vane water meter body 1 is an existing product on the market, these structures will not be described in detail here. They are only used to explain the relationship between the structures and as a basis for reference, and only for the convenience of interpretation and writing.
[0026] Both the inlet pipe 101 and the outlet pipe 102 are fixedly fitted with retaining rings 2. The top and bottom of the outer surface of the retaining ring 2 are movably inserted with locking blocks 3. A movable block 4 is fixedly connected to the inner side of the locking block 3, and the movable block 4 is slidably connected to the retaining ring 2. A spring 5 is fixedly connected to the inner side of the movable block 4, and the spring 5 is currently in a compressed state. The inner end of the spring 5 is fixedly connected to the inner wall of the retaining ring 2. Limiting grooves 6 are provided on both the front and rear sides of the outer surface of the retaining ring 2. The outer surface of the retaining ring 2 is movably fitted with... There is a sleeve 7, and the outer side of the locking block 3 is tightly attached to the inner wall of the sleeve 7. The inner walls of the two sets of sleeves 7 are in movable contact with the outer surfaces of the inlet pipe 101 and the outlet pipe 102, respectively. Limiting blocks 8 are fixedly connected to the front and rear sides of the inner wall of the sleeve 7. The limiting blocks 8 are slidably connected to the limiting groove 6. The inner side of the outer surface of the sleeve 7 is provided with a vertically penetrating locking groove 9. The inner wall of the sleeve 7 is fixedly connected with a sealing element 10. The inner walls of the two sets of sealing elements 10 are in movable contact with the outer surfaces of the inlet pipe 101 and the outlet pipe 102, respectively.
[0027] With the external thread 103, the inlet pipe 101 and outlet pipe 102 can be threadedly connected to two sets of external water pipes respectively. Then, the sleeve 7 is moved outward until the inner wall of the sealing element 10 is tightly attached to the connection between the inlet pipe 101 and outlet pipe 102 and the two sets of external water pipes respectively. Then, the spring 5 drives the locking block 3 to insert into the slot 9 to lock the sleeve 7. Because of the presence of the sealing element 10, the sealing performance of the connection between the inlet pipe 101 and outlet pipe 102 and the two sets of external water pipes can be increased, preventing water from overflowing through the gaps between the connections. Therefore, water resources will not be wasted continuously. At the same time, it also prevents the phenomenon that the rotary vane water meter body 1 will slowly measure the wasted water resources due to water leakage at the connection, which would directly cause economic losses to residents.
[0028] The reaction force generated by the compression of the return spring 5 continuously compresses the moving block 4 outward, which makes the locking block 3 firmly inserted into the slot 9, ensuring the stability of the sleeve 7 being locked and indirectly improving the sealing effect of the sealing element 10.
[0029] By sliding the limiting block 8 along the inside of the limiting groove 6, the moving sleeve 7 can be limited, preventing the sleeve 7 from rotating when the operator moves it, which would cause the slot 9 to fail to align with the block 3, thus improving the practicality of the device.
[0030] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation.
[0031] In order to protect the instrument body 104, this utility model has a connecting ring 11 fixedly sleeved on the top of the outer surface of the rotary vane water meter body 1, and a top cover 12 movably sleeved on the top of the outer surface of the connecting ring 11. Because of the setting of the top cover 12, the instrument body 104 can be shielded, preventing the surface of the instrument body 104 from becoming blurry due to prolonged exposure to the external environment, thus making it inconvenient for staff to read the data of the instrument body 104, thereby achieving the protection of the instrument body 104.
[0032] In order to facilitate the vertical movement of the movable block 4 inside the fixed ring 2, a movable groove is provided inside the fixed ring 2. The inner diameter of the movable groove is adapted to the outer diameter of the movable block 4. Because the two sets of structural dimensions are adapted, it is convenient for the movable block 4 to move vertically inside the fixed ring 2.
[0033] In order to extend the service life of the spring 5, this utility model sets the number of springs 5 to several groups. The material of the several groups of springs 5 is all set to silicon manganese spring steel. Springs 5 made of silicon manganese spring steel have good rebound effect, are not easily deformed, and extend the service life of springs 5.
[0034] In order to achieve the snap-fit of the sleeve 7, the present invention sets the number of slots 9 to several groups. The inner diameter of each group of slots 9 is adapted to the outer diameter of the snap-fit block 3. Therefore, when the sleeve 7 moves the slots 9 to a position perpendicular to the snap-fit block 3, the reaction force generated by the compressed spring 5 can drive the snap-fit block 3 into the inside of the slots 9, thereby achieving the snap-fit of the sleeve 7.
[0035] To ensure that the fixing ring 2, locking block 3, moving block 4, sleeve 7, and limiting block 8 are not easily damaged during use, this utility model uses stainless steel as the material for all of them. The stainless steel support structure has high strength, is not easily deformed, and is not easily rusted or broken. Therefore, it ensures that the fixing ring 2, locking block 3, moving block 4, sleeve 7, and limiting block 8 are not easily damaged during use, thus extending their service life.
[0036] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.
[0037] In use, the operator first prepares two sets of external water pipes. Then, internal threads matching the size of the external thread 103 are cut into the inner walls of the connection ends of each set of external water pipes. Due to the external and internal threads, the operator can thread the two sets of external water pipes to the inlet pipe 101 and outlet pipe 102 respectively. After connection, if a slight deviation in the size of the internal and external threads 103 causes overflow at the connection, the operator can control the sleeve 7 to move the groove 9 and the seal 10 outwards along the outer surface of the fixing ring 2. Simultaneously, the sleeve 7 moves the limiting block 8 outwards along the inside of the limiting groove 6 until it reaches the designated position. The position of the sleeve 7 ensures that the inner wall of the seal 10 is tightly attached to the connection points between the inlet pipe 101 and the outlet pipe 102 and the two sets of external water pipes, respectively. At the same time, the sleeve 7 moves the slot 9 to a position perpendicular to the locking block 3. At this time, the inner wall of the sleeve 7 releases its obstruction of the locking block 3, allowing the reaction force generated by the spring 5 under compression to drive the moving block 4 and the locking block 3 to move outward along the inside of the fixing ring 2 until the locking block 3 is inserted into the inside of the slot 9, which can lock and fix the sleeve 7. This ensures that the seal 10 is firmly attached to the connection points between the inlet pipe 101 and the outlet pipe 102 and the two sets of external water pipes, enhancing the sealing of the connection points and preventing water overflow at the waterproof connection points.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
