[0029] To illustrate the technical solutions described in the present utility model, the following will be described by specific examples, and only the parts related to the embodiments of the present utility model are shown.

[0030] Embodiment 1:

[0031] As Figure 1As shown in the figure, the present utility model provides a sealing structure for an external antenna, which includes a seal 1 and a mounting base 2. The seal 1 is detachably connected to the mounting base 2, and both the seal 1 and the mounting base 2 are correspondingly arranged with the antenna hole 321 of the intelligent single-phase meter housing 3. The seal 1 includes a corresponding first sealing wall 11 and a second sealing wall 12. Both the first sealing wall 11 and the second sealing wall 12 are matched with the mounting base 2. When the first sealing wall 11 is detachably connected to the mounting base 2, the antenna hole 321 can be opened. When the second sealing wall 12 is detachably connected to the mounting base 2, the antenna hole 321 can be sealed. Specifically, the seal 1 is detachably connected to the mounting base 2. Users can detachably connect the first sealing wall 11 or the second sealing wall 12 of the seal 1 to the mounting base 2 according to the need for an external antenna 4, improving the user experience. When an external antenna 4 needs to be installed, the first sealing wall 11 is detachably connected to the mounting base 2, and the antenna hole 321 can be opened, enabling the external antenna 4 to pass through the antenna hole 321. When the external antenna 4 does not need to be installed, the second sealing wall 12 is detachably connected to the mounting base 2, and the seal 1 corresponding to the antenna hole 321 can seal the antenna hole 321, protecting the components inside the intelligent single-phase meter housing and increasing the service life of the intelligent single-phase meter. Since both the first sealing wall 11 and the second sealing wall 12 are detachably connected to the mounting base 2, it is convenient for users to switch the antenna hole 321 between a sealed state and an open state. The first sealing wall 11 and the second sealing wall 12 are symmetrical. By simply rotating the seal 1 by 180 degrees, the positions of the first sealing wall 11 and the second sealing wall 12 can be adjusted, facilitating the installation of the first sealing wall 11 or the second sealing wall 12 on the mounting base 2. The upper end of the first sealing wall 11 is connected to the upper end of the second sealing wall 12 through a connecting part.

[0032] According to the need for an external antenna 4, the present utility model detachably connects the first sealing wall 11 or the second sealing wall 12 of the seal 1 to the mounting base 2, improving the sealing effect of the antenna hole 321 for installing the external antenna 4, being easy to use, and enhancing the user experience.

[0033] As an optional implementation manner, such as Figure 3As shown in the figure, both the first sealing wall 11 and the second sealing wall 12 include ridges 13. The ridges 13 are provided on both sides of the first sealing wall 11 and the second sealing wall 12. The ridges 13 are matched with the card slots 21 of the mounting base 2. The first sealing wall 11 or the second sealing wall 12 is clamped in the card slot 21. Specifically, ridges 13 are provided on both sides of the first sealing wall 11 and both sides of the second sealing wall 12. Since both the first sealing wall 11 and the second sealing wall 12 are matched with the mounting base 2, and the ridges 13 are matched with the card slots 21, when the first sealing wall 11 is placed above the mounting base 2, the ridges 13 of the first sealing wall 11 can be clamped into the card slots 21 to clamp and connect the first sealing wall 11 to the mounting base 2; when the second sealing wall 12 is placed above the mounting base 2, the ridges 13 of the second sealing wall 12 can be clamped into the card slots 21 to clamp and connect the second sealing wall 12 to the mounting base 2. Both the first sealing wall 11 and the second sealing wall 12 are matched with the mounting base 2, and the ridges 13 are matched with the card slots 21, ensuring that the seal 1 can be stably fixed to the mounting base 2.

[0034] As an alternative embodiment, as Figure 4 shown, the first sealing wall 11 further includes a recess 14. The recess 14 is provided at the bottom of the first sealing wall 11; when the ridges 13 of the first sealing wall 11 are clamped in the card slots 21, the recess 14 corresponds to and is matched with the groove 22 of the mounting base 2, and the recess 14 and the groove 22 cooperate to form a through-hole structure 6. The through-hole structure 6 can communicate the antenna hole 321 with the internal space of the intelligent single-phase meter housing 3. Specifically, a recess 14 is provided at the bottom of the first sealing wall 11, and a groove 22 is provided on the mounting base 2. When the ridges 13 of the first sealing wall 11 are clamped in the card slots 21, the corresponding recess 14 and groove 22 cooperate to form a through-hole structure 6. The groove 22 of the mounting base 2 corresponds to the antenna hole 321, so that the through-hole structure 6 corresponds to the antenna hole 321. The antenna hole 321 is communicated with the internal space of the intelligent single-phase meter housing 3 through the through-hole structure 6. One end of the external antenna 4 can sequentially pass through the through-hole structure 6 and the antenna hole 321 and be placed outside the intelligent single-phase meter housing 3.

[0035] As an alternative embodiment, the outer diameter of the cross-section of the through-hole structure 6 is smaller than the outer diameter of the cross-section of the external antenna 4. When the external antenna 4 passes through the through-hole structure 6 and the antenna hole 321, the external antenna 4 is in interference fit with the through-hole structure 6. Specifically, the outer diameter of the cross-section of the through-hole structure 6 is smaller than the outer diameter of the cross-section of the external antenna 4. After the external antenna 4 passes through the through-hole structure 6, the seal 1 with elastic properties restores the deformation that occurs when the external antenna 4 passes through the through-hole structure 6, so that the external antenna 4 is in interference fit with the through-hole structure 6, ensuring the sealing performance at the contact position between the external antenna 4 and the through-hole structure 6. The outer diameter of the cross-section of the external antenna 4 is preferably 3 mm, and the outer diameter of the cross-section of the through-hole structure 6 is preferably 2.8 mm. In addition, external antennas 4 of different sizes can also be selected according to requirements, and the size of the through-hole structure 6 can be adaptively set.

[0036] As an alternative embodiment, as Figure 4 shown, the second sealing wall 12 further includes a convex portion 15. The convex portion 15 is provided at the bottom of the second sealing wall 12. When the ridge 13 of the second sealing wall 12 is engaged in the card slot 21, the convex portion 15 corresponds to and matches the groove 22 of the mounting base 2, and the convex portion 15 is disposed in the groove 22. Specifically, a convex portion 15 is provided at the bottom of the second sealing wall 12, and a groove 22 is provided on the mounting base 2. When the ridge 13 of the second sealing wall 12 is engaged in the card slot 21, since the convex portion 15 and the groove 22 correspond to and match each other, the convex portion 15 can be placed in the groove 22 and fill the groove 22. The groove 22 of the mounting base 2 corresponds to the antenna hole 321. After the groove 22 is filled by the convex portion 15, the convex portion 15 corresponding to the antenna hole 321 and the second sealing wall 12 can seal and block the antenna hole 321.

[0037] As an alternative embodiment, the material of the seal 1 is silicone. Specifically, the silicone material has good elastic properties. When the external antenna 4 passes through the through-hole structure 6, the first sealing wall 11 can undergo elastic deformation by the applied force, and the concave portion 14 of the first sealing wall 11 becomes larger, facilitating the external antenna 4 to pass through the through-hole structure 6. After the external antenna 4 is installed, the elastic deformation of the first sealing wall 11 is restored, and the through-hole structure 6 is in interference fit with the external antenna 4, improving the sealing performance at the contact position between the external antenna 4 and the sealing structure. In addition, when the first sealing wall 11 or the second sealing wall 12 is detachably connected to the mounting base 2, the ridge 13 on the first sealing wall 11 or the second sealing wall 12 undergoes elastic deformation by the action of force. After the ridge 13 on the first sealing wall 11 or the second sealing wall 12 is engaged in the card slot 21 of the mounting base 2, the elastic deformation of the ridge 13 is restored, so that the card slot 21 and the ridge 13 are in interference fit, and the seal 1 is firmly fixed on the mounting base 2.

[0038] As an alternative embodiment, as Figure 2As shown, the mounting seat 2 is provided on the inner wall of the intelligent single-phase meter housing 3, and the seal 1 is fixed on the mounting seat 2 and can abut against the inner wall of the intelligent single-phase meter housing 3. Specifically, since the mounting seat 2 is provided on the inner wall of the intelligent single-phase meter housing 3, when the seal 1 is fixed on the mounting seat 2, the seal 1 can abut against the inner wall of the intelligent single-phase meter housing 3. When the second sealing wall 12 is engaged on the mounting seat 2, since the second sealing wall 12 abuts against the inner wall of the intelligent single-phase meter housing 3, the second sealing wall 12 and the convex portion 15 on the second sealing wall 12 can seal the antenna hole 321 on the intelligent single-phase meter housing 3, meeting the user's sealing requirement for the installation location of the external antenna 4 and improving the user experience.

[0039] As an optional implementation manner, as Figure 1 and Figure 5 shown, the intelligent single-phase meter housing 3 includes a bottom shell 31 and an upper cover 32. The upper cover 32 is matched with the bottom shell 31, and the upper cover 32 is detachably connected to the bottom shell 31; the upper cover 32 includes an antenna hole 321 and a reinforcing rib 322; when the upper cover 32 is connected to the bottom shell 31, the antenna hole 321 corresponds to the groove 22, and the reinforcing rib 322 corresponds to and abuts against the first sealing wall 11 or the second sealing wall 12 fixed in the card slot 21. Specifically, the upper cover 32 is matched with the bottom shell 31, and the upper cover 32 can be snapped onto the bottom shell 31 and is further fixed by screws. The reinforcing rib 322 in the upper cover 32 corresponds to the seal 1 of the sealing structure. After the upper cover 32 is closed on the bottom shell 31, the reinforcing rib 322 can apply pressure to the mutually abutting seal 1, pressing the seal 1 tightly fixed on the mounting seat 2 to prevent the seal 1 from falling off or loosening and ensuring the sealing performance of the seal 1 for the antenna hole 321. When the upper cover 32 is connected to the bottom shell 31, the antenna hole 321 corresponds to the groove 22, ensuring that the seal 1 abutting against the inner wall of the intelligent single-phase meter housing 3 completely seals the antenna hole 321.

[0040] As an optional implementation manner, as Figure 2 shown, the mounting seat 2 and the bottom shell 31 are of an integral structure. Specifically, the mounting seat 2 and the bottom shell 31 being of an integral structure ensures the structural stability and facilitates processing and production.

Specifically, the communication module 5 is arranged inside the intelligent single-phase meter housing 3 and is protected by the intelligent single-phase meter housing 3 to improve the service life of the intelligent single-phase meter. The communication module 5 is used to transmit the collected electricity consumption information. The sealing structure is arranged inside the intelligent single-phase meter housing 3 to seal the antenna hole 321 inside the intelligent single-phase meter housing 3, ensure the sealing performance of the intelligent single-phase meter, and improve the service life of the intelligent single-phase meter. The sealing structure abuts against the antenna hole 321 of the intelligent single-phase meter housing 3, which can improve the sealing of the antenna hole 321. The external antenna 4 is electrically connected to the communication module 5, enabling the communication module 5 to transmit and receive information through the external antenna 4. The external antenna 4 passes through the through-hole structure 6 formed by the sealing structure and the antenna hole 321 and is arranged outside the intelligent single-phase meter, facilitating the external antenna 4 to receive signals.

[0043] The intelligent single-phase meter of the present utility model can adjust the installation of the seal 1 according to whether the user needs the external antenna 4, ensuring that the antenna hole 321 can be sealed whether the external antenna 4 is needed or not. At the same time, when the external antenna 4 is needed, the external antenna 4 can pass through the antenna hole 321 to meet the different needs of users and improve the user experience.
