Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic water meter technology, specifically relating to an electromagnetic water meter with good sealing performance. Background Technology

[0002] An electromagnetic water meter is a high-precision smart water meter based on the Faraday principle of electromagnetic induction, primarily used for the accurate measurement and monitoring of water flow. Its core principle is that when a conductive fluid (such as water) flows through a magnetic field, it cuts the magnetic field lines, generating an induced electromotive force. This electromotive force is proportional to the flow velocity and is detected by electrodes, converting it into flow rate data.

[0003] Electromagnetic water meters require a sealed connection with external water pipes during installation. However, existing electromagnetic water meters often only use a snap-fit ​​mechanism to achieve this connection, resulting in insufficient clamping between the meter and the pipe. This allows for the creation of large gaps under environmental influences, compromising the seal. Therefore, a more reliable electromagnetic water meter with superior sealing performance is urgently needed.

[0004] A patent with publication number CN220649661U discloses a water meter that is easy to clean. It includes a water meter, a water pipe, a first connecting ring, a second connecting ring, an L-shaped rod, a slot, a turntable, a lead screw, a sliding plate, a push rod, and a spring. When connecting the water meter to the water pipe, the first and second connecting rings are aligned, allowing the L-shaped rod to insert into the slot. Subsequently, rotating the turntable causes the lead screw to rotate, and the sliding plate pushes the push rod, thereby using the elasticity of the spring to lock the L-shaped rod into the slot, thus completing the engagement of the first and second connecting rings.

[0005] However, the above solution, which relies on the elasticity of the spring, can only achieve the engagement between the first and second connecting rings. There is no clamping force between the first and second connecting rings, making them prone to gaps under the influence of the external environment, resulting in poor sealing performance and mediocre practical effect. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model provides an electromagnetic water meter with good sealing performance.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An electromagnetic water meter with good sealing performance includes an electromagnetic water meter body and water pipes located at both ends of the electromagnetic water meter body. An installation plate is fixedly mounted on both the input and output ends of the electromagnetic water meter body, and a fixing plate is fixedly mounted on each of the two water pipes, with the installation plate and fixing plate corresponding one-to-one. Each installation plate has two sets of linkage mechanisms, each set of linkage mechanisms including two sliding frames that slide towards or away from each other, each sliding frame being inclined. Each sliding frame is slidably connected to an L-shaped rod via a connector, the sliding direction of the L-shaped rod being the same as the inclination direction of the sliding frame. Several slots are formed on the fixing plate, and the L-shaped rods are correspondingly engaged with the slots for transmission and locking.

[0009] Furthermore, the linkage mechanism also includes a bidirectional threaded rod, which is rotatably mounted inside the mounting plate. One end of the bidirectional threaded rod rotatably passes through the mounting plate and is fixedly mounted with a knob, while the other end of the bidirectional threaded rod is rotatably connected to the mounting plate. A moving block is fixedly mounted on the outer surface of each sliding frame, and the moving blocks in the same linkage mechanism are threadedly connected to the threaded sections of the bidirectional threaded rod in a one-to-one correspondence.

[0010] Furthermore, a sliding block is fixedly provided on the outer surface of each sliding frame, and a second guide rod is fixedly provided inside the mounting plate, with the sliding block slidably sleeved on the outer surface of the second guide rod.

[0011] Furthermore, the connector includes a first guide rod, and the sliding frame is provided with a groove along its own inclined direction and the first guide rod is fixedly installed along its own inclined direction; the L-shaped rod is both limited and slidably installed in the groove and slidably sleeved on the outer surface of the first guide rod.

[0012] Furthermore, an elastic element is provided between the L-shaped rod and the sliding frame. The elastic element includes a spring, which is sleeved on the outer surface of the first guide rod. One end of the spring is fixedly connected to the sliding frame, and the other end is fixedly connected to the L-shaped rod.

[0013] Furthermore, a first sealing ring is fixedly installed inside the mounting plate, and a second sealing ring is fixedly installed inside the fixing plate, with the first sealing ring and the second sealing ring being compatible.

[0014] This application has the following beneficial effects:

[0015] After the mounting plate and the fixing plate are attached, the linkage mechanism drives the two sliding frames to slide back and forth, thereby engaging the L-shaped rod into the slot, thus completing the engagement between the mounting plate and the fixing plate. Simultaneously, after the L-shaped rod is engaged, the sliding frame pulls the L-shaped rod through the connector, creating a clamping force between the mounting plate and the fixing plate. This prevents gaps from forming between the mounting plate and the fixing plate due to external environmental influences, ensuring a good seal and improving practicality. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: an electromagnetic water meter with good sealing performance includes an electromagnetic water meter body 1 and water pipes 2 located at both ends of the electromagnetic water meter body 1. The input end and the output end of the electromagnetic water meter body 1 are both fixedly provided with mounting plates 3. The ends of the two water pipes 2 facing the electromagnetic water meter body 1 are both fixedly provided with fixing plates 4. The mounting plates 3 and fixing plates 4 correspond one-to-one.

[0025] Each mounting plate 3 is equipped with two sets of linkage mechanisms. Each set of linkage mechanisms includes two sliding frames 9 that slide towards or away from each other, and each sliding frame 9 is inclined. Each sliding frame 9 is limited and slidably equipped with an L-shaped rod 12 by a connector. The sliding direction of the L-shaped rod 12 is the same as the inclination direction of the sliding frame 9. Each fixing plate 4 has several slots 15. The number of L-shaped rods 12 and slots 15 are equal and correspond one-to-one. Each L-shaped rod 12 is engaged with the corresponding slot 15.

[0026] The linkage mechanism also includes a bidirectional threaded rod 7, which is rotatably mounted inside the mounting plate 3. One end of the bidirectional threaded rod 7 rotatably passes through the mounting plate 3 and is fixedly mounted with a knob 14. The other end of the bidirectional threaded rod 7 is rotatably connected to the mounting plate 3. A moving block 8 is fixedly mounted on the outer surface of each sliding frame 9. The moving blocks 8 in the same linkage mechanism are threadedly connected to the threaded sections of the bidirectional threaded rod 7 one-to-one.

[0027] Furthermore, a sliding block (not shown in the figure) is fixedly installed on the outer surface of each sliding frame 9, and a second guide rod 13 is fixedly installed inside the mounting plate 3, with the sliding block slidably sleeved on the outer surface of the second guide rod 13.

[0028] The connector includes a first guide rod 10, and the sliding frame 9 has a groove along its own inclined direction and the first guide rod 10 is fixedly installed along its own inclined direction. The L-shaped rod 12 is both limited and slidably installed in the groove and slidably sleeved on the outer surface of the first guide rod 10. At the same time, an elastic element is provided between the L-shaped rod 12 and the sliding frame 9.

[0029] Specifically, the elastic element includes a spring 11, which is sleeved on the outer surface of the first guide rod 10. One end of the spring 11 is fixedly connected to the sliding frame 9, and the other end is fixedly connected to the L-shaped rod 12.

[0030] In addition, a first sealing ring 5 is fixedly installed inside the mounting plate 3, and a second sealing ring 6 is fixedly installed inside the fixing plate 4. The first sealing ring 5 and the second sealing ring 6 are compatible.

[0031] Working principle: During installation, the mounting plate 3 of the electromagnetic water meter body 1 is attached to the fixing plate 4 of the water pipe 2, so that the second sealing ring 6 and the first sealing ring 5 are sealed and attached, and the L-shaped rod 12 on the mounting plate 3 is inserted into the slot 15 opened in the fixing plate 4.

[0032] Subsequently, the knob 14 is turned, causing the bidirectional threaded rod 7 to rotate. The bidirectional threaded rod 7, through the moving block 8, causes the two sliding frames 9 to slide away from each other. During this process, the sliding block slides on the outer surface of the second guide rod 13 to ensure the stability of the sliding frames 9 during sliding.

[0033] Under the elastic resistance of the spring 11, the sliding frame 9 slides and drives the L-shaped rod 12 to slide synchronously, so that the L-shaped rod 12 is inserted into the slot 15 to complete the engagement between the mounting plate 3 and the fixing plate 4.

[0034] As the sliding frame 9 continues to move, the L-shaped rod 12 abuts against the slot 15 and no longer slides. Subsequently, the sliding frame 9 drives the L-shaped rod 12 to slide on the outer surface of the first guide rod 10 and compress the spring 11. Because the first guide rod 10 is inclined, the L-shaped rod 12 slides towards one side of the mounting plate 3, causing the mounting plate 3 and the fixing plate 4 to fit tightly together, and causing the first sealing ring 5 and the second sealing ring 6 to fit tightly together.

[0035] At the same time, the L-shaped rod 12 will also generate a clamping force between the mounting plate 3 and the fixing plate 4, thereby preventing gaps from forming between the mounting plate 3 and the fixing plate 4 under the influence of the external environment, ensuring a sealing effect and providing better practicality.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
