Description

Technical Field

[0001] The utility model relates to the technical field of water meter actuators, in particular to a fully sealed actuator for an intelligent water meter. Background Art

[0002] A smart water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology, and smart IC card technology to measure water consumption and transmit water usage data and settle transactions. However, existing water meters have a simple structure and average sealing effect, and are easily affected by the outside world. When the outside humidity is too high, some moisture will enter the water meter, causing the water meter display to be blurred, affecting the use of the water meter. When it rains outside, water can easily enter the water meter, affecting the use of the water meter.

[0003] In order to solve the above problems, the national publication number CN207163517U discloses "a water meter actuator with sealing protection function". The positioning column of the box cover is installed into the bottom frame of the actuator box to achieve the purpose of fastening the box cover and the bottom of the box. At this time, the bubble release column with a central hole is automatically inserted into the liquid glue to release the bubbles in it through the central hole to achieve the desired sealing effect. Through the upper glue injection groove and the bottom glue injection groove, the bottom glue injection groove is injected with a sealant that is not easy to flow, and the upper glue injection groove is injected with a sealant that is easy to flow. The liquid level covers the height of the water meter actuator by two-thirds to achieve the sealing purpose, and the sealing effect is excellent. However, the device still has certain defects in actual use. For example, the device uses a glue injection method to ensure the sealing of the water meter actuator. Although this method can ensure the sealing of the water meter actuator, the water meter actuator will be difficult to disassemble after the sealant solidifies, resulting in the water meter actuator being unable to be used normally. It is difficult to repair the electronic components inside the water meter actuator. The entire water meter actuator can only be replaced, increasing the use cost of the water meter actuator.

[0021] The embodiment of the present application provides a fully sealed actuator for a smart water meter, which can realize the installation connection between the actuator housing and the box cover by threaded connection between the threaded rod and the threaded hole, so that the box cover and the actuator housing can be detached and separated, and the sealing inside the actuator housing is ensured by the sealing component, and the threaded rod can be protected by the protective component to avoid the problem of easy corrosion and rust of the threaded rod directly exposed to the air, thereby ensuring that the threaded rod can be normally disassembled. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0022] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example 1

[0023] See also Figure 1-8In the embodiment, a fully sealed actuator of a smart water meter is provided, comprising: an actuator housing 1, a box cover 101, a through hole 102, a threaded rod 103, a sealing component and a protective component. The box cover 101 is arranged on one side of the outer end of the actuator housing 1, and a plurality of through holes 102 are opened on one side of the outer end of the box cover 101. The threaded rod 103 is arranged inside the through hole 102. A sealing component is arranged between the box cover 101 and the actuator housing 1 to ensure the sealing inside the actuator housing 1. The protective component arranged on one side of the outer end of the box cover 101 is used to protect the threaded rod 103.

[0024] The sealing assembly includes: a sealing groove 2 opened on one side of the outer end of the actuator housing 1, a sealing block 201 connected to one side of the outer end of the box cover 101 and slidably connected to the sealing groove 2, and a fitting block 202 installed inside the sealing groove 2. When the box cover 101 needs to be installed and connected with the actuator housing 1, the side of the sealing block 201 away from the box cover 101 is inserted into the sealing groove 2, and one side of the sealing block 201 is fitted with the fitting block 202, and one side of the box cover 101 is fitted with one side of the outer end of the rubber plate 3, and then the threaded rod 101 is inserted into the sealing groove 2. 3 is put into the connecting ring 5 and passes through the through hole and then rotated into the threaded hole 4 to be connected with the inner thread of the threaded hole 4. As one end of the threaded rod 103 is rotated into the threaded hole 4, the box cover 101 can be pushed to fit tightly with the rubber plate 3, and the box cover 101 drives one side of the sealing block 201 to fit tightly with the fitting block 202, thereby ensuring the connection sealing between the box cover 101 and the actuator housing 1, wherein the sealing block 201 and the rubber plate 3 are both made of rubber material, so that the sealing block 201 and the rubber plate 3 have good sealing properties.

[0025] Among them, a rubber plate 3 is installed on one side of the outer end of the actuator housing 1, and a through groove consistent with the shape of the sealing groove 2 is opened on one side of the outer end of the rubber plate 3, wherein the through groove is used to ensure that one side of the sealing block 201 can move into the sealing groove 2, so that the rubber plate 3 will not affect the installation connection between the box cover 101 and the actuator housing 1, and after the box cover 101 and the actuator housing 1 are installed, the actuator housing 1 is assembled on the water meter.

[0026] Among them, one side of the outer end of the actuator housing 1 is provided with a plurality of threaded holes 4 threadedly connected to the threaded rod 103, and one side of the outer end of the rubber plate 3 is provided with a plurality of through holes. When it is necessary to maintain and overhaul the components inside the actuator housing 1, the protective column 501 is rotated to be removed from the outside of the connecting ring 5, and then the threaded rod 103 is rotated to rotate out of the threaded hole 4, and then one end of the threaded rod 103 is taken out from the through hole, and then the box cover 101 is moved to the side away from the actuator housing 1 until the box cover 101 drives the sealing block 201 to slide out of the sealing groove 2. At this time, the components inside the actuator housing 1 can be maintained and overhauled, and the through hole enables one end of the threaded rod 103 to pass through the rubber plate 3 and be inserted into the threaded hole 4, thereby ensuring that the threaded rod 103 can be threadedly connected to the threaded hole 4. Example 2

[0027] Among them, the protection component includes: a plurality of connecting rings 5 ​​connected to one side of the outer end of the box cover 101 in a circular shape, a protection column 501 arranged on the outer side of the connecting ring 5, and a connecting hole 502 opened on the side of the protection column 501 close to the connecting ring 5. When the box cover 101 and the actuator housing 1 are installed using the threaded rod 103, one end of the threaded rod 103 will protrude from one side of the outer end of the box cover 101 and be located in the connecting ring 5. At this time, the protection column 501 can be rotated to the outside of the connecting ring 5 through the connecting hole 502, and the protection column 501 can be installed on the outside of the connecting ring 5 by threading the outer side of the connecting ring 5 with the inner wall of the connecting hole 502. The connecting ring 5 and the threaded rod 103 inside the connecting ring 5 are protected by the protection column 501 to avoid the threaded rod 103 being directly exposed to the air and being easily corroded by moisture, thereby ensuring that the threaded rod 103 can be disassembled later.

[0028] Among them, the outer side of the connecting ring 5 is threadedly connected to the inner wall of the connecting hole 502, and a circular sealing ring 6 is connected to one side of the outer end of the protective column 501. Both sides of the outer end of the protective column 501 are connected to cross bars 601. When the protective column 501 is rotated to be threadedly connected to the connecting ring 5, until the protective column 501 drives the sealing ring 6 to rotate and move until it is tightly fitted with the box cover 101, the sealing ring 6 is made of rubber material, so that the sealing ring 6 can fit tightly with the box cover 101, and the two cross bars 601 are convenient for the user to rotate the protective column 501. Example 3

[0029] A transparent frame 7 is embedded on one side of the outer end of the box cover 101 , and the outer end of the box cover 101 is tightly fitted with the rubber plate 3 , wherein the transparent frame 7 enables electronic components in the actuator housing 1 to be visible without separating the box cover 101 and the actuator housing 1 .
