Description

Technical Field

[0001] This application relates to the field of smart meters, and in particular to a smart meter. Background Technology

[0002] In current smart meter metering management, a lead seal structure is installed between the meter body and the outer cover to protect the meter. The commonly used lead seal structure has a locking component with a lead seal hole through its head. During installation, workers typically use a screwdriver to twist the locking component, thus locking the meter body and the outer cover together. Then, a lead seal wire is threaded through the lead seal hole between the outer cover and the locking component to complete the lead seal installation. After removing the lead seal, workers again use a screwdriver to turn the locking component to loosen the meter body, allowing them to remove the locking component from the outer cover. Both the installation and removal of the locking component require tools such as screwdrivers, and the process is cumbersome, time-consuming, and increases labor costs. Utility Model Content

[0029] Figure 1 and Figure 2 A schematic diagram of the structure of a smart meter is shown. Figure 1 The smart meter is in a locked state. Figure 2 The smart meter is in a state where the lead seal is removed.

[0030] This application discloses a smart meter, which includes a meter body 1, an outer cover 2, a locking component 3, and an operating component 4.

[0031] The outer cover 2 is fitted onto the meter body 1, and a lead seal groove 21 is provided on the outer side wall of the outer cover 2. The bottom of the lead seal groove 21 is provided with a mounting hole 22.

[0032] Reference Figure 1 The top of the locking member 3 is located within the lead seal groove 21, and the locking member 3 is used to lock the outer cover 2 with the lead seal. The bottom of the locking member 3 passes through the mounting hole 22 and is locked and connected to the meter body 1. The locking member 3 is rotatably disposed within the mounting hole 22, and the locking member 3 can rotate relative to the mounting hole 22 to lock or unlock the bottom of the locking member 3 with the meter body 1. The operating member 4 is located within the lead seal groove 21. The operating member 4 has a spaced-apart rotating side and a swinging side. The rotating side of the operating member 4 is rotatably connected to the top of the locking member 3, so that the swinging side of the operating member 4 can rotate relative to the locking member 3 and protrude from the top of the locking member 3.

[0033] In the smart meter of this application, the operator can rotate the operating member 4 relative to the locking member 3, so that the operating member 4 can flip out relative to the locking member 3 until it protrudes beyond the top of the locking member 3, such as... Figure 2 As shown, this allows the operator to easily rotate the operating component 4 by grasping the locking component 3, thereby facilitating the rotation of the locking component 3 relative to the mounting hole 22 on the outer cover 2. This allows the bottom of the locking component 3 to be locked or unlocked against the meter body 1. This application, through the design of the operating component 4, enables tool-free installation and removal of the locking component 3 on the smart meter. The operation is simple and easy to apply force, allowing operators to quickly and manually install and remove the locking component 3 between the meter body 1 and the outer cover 2, reducing installation and maintenance costs. Figure 1 As shown, after the installation of the locking member 3 is completed, the operating member 4 can rotate relative to the locking member 3 and be housed in the lead seal groove 21.

[0034] Figure 3 An exploded view of the structure of a smart meter is shown. Figure 4 A schematic diagram of the locking element 3 is shown.

[0035] Reference Figure 3 and Figure 4 The locking member 3 includes a rod 31 and a head 32. One axial end of the rod 31 is connected to the bottom of the head 32, and the other axial end of the rod 31 passes through the mounting hole 22 and can rotate relative to the outer cover 2.

[0036] Specifically, the outer diameter of the head 32 is larger than the inner diameter of the mounting hole 22, allowing the head 32 to be engaged outside the mounting hole 22 and accommodated within the lead seal groove 21. The top end of the rod 31 connects to the head 32, and the outer diameter of the rod 31 is smaller than the inner diameter of the mounting hole 22, allowing the rod 31 to pass through the mounting hole 22, thus positioning the locking member 3 on the outer cover 2. The rod 31 can rotate within the mounting hole 22, thereby locking or unlocking its bottom to the meter body 1. The head 32 can be locked with the lead seal of the outer cover 2. The operating member 4 is rotatably connected to the head 32. The operating member 4 can protrude from the top of the head 32 by rotating relative to it, facilitating the operator to control the rotation of the entire locking member 3 by twisting the operating member 4.

[0037] Furthermore, the bottom surface of the head 32 is provided with a mounting groove 33, and the operating member 4 is provided with a rotating shaft 41, which is detachably locked in the mounting groove 33. During installation, the rotating shaft 41 of the operating member 4 is locked in the mounting groove 33, which is convenient and quick. In addition, the mounting groove 33 can restrict the movement of the rotating shaft 41 towards the top of the locking member 3. When it is necessary to adjust the locking state between the locking member 3 and the meter body 1, the operating member 4 flips to the top of the locking member 3 and can control the rotation of the locking member 3, thereby reducing the possibility of the operating member 4 falling off the locking member 3 and improving the installation stability of the operating member 4. It should be noted that the axial extension direction of the rotating shaft 41 is the same as the extension direction of the rotation axis of the operating member 4.

[0038] In some embodiments, the cross-sectional shape of the mounting groove 33 may be inverted U-shaped. Specifically, the mounting groove 33 includes an extension section and a rotating section. One side of the extension section is connected to the rotating section, and the other side of the extension section extends to the bottom surface of the head 32. The rotating shaft 41 is engaged in the rotating section. The width of the extension section relative to the two side walls gradually decreases towards the rotating section to be smaller than the outer diameter of the rotating shaft 41, so that the rotating shaft 41 can be stably engaged in the rotating section without falling off.

[0039] In some other embodiments, the side wall of the head 32 is provided with a rotating shaft 41, and the top surface of the operating member 4 is provided with a mounting groove 33. The rotating shaft 41 is detachably locked in the mounting groove 33 to facilitate the installation of the operating member 4.

[0040] In order to determine the rotation angle of the locking member 3 relative to the mounting hole 22 so that the locking member 3 can rotate into place, the bottom of the lead seal groove 21 is provided with a limiting protrusion spaced apart from the mounting hole 22, and the top side wall of the locking member 3 is formed with a stop surface 321. The stop surface 321 can abut against the limiting protrusion as the locking member 3 rotates relative to the outer cover 2, which can limit the continued rotation of the locking member 3 relative to the outer cover 2, thereby ensuring that the locking member 3 rotates into place to lock or unlock with the meter body 1.

[0041] Specifically, the limiting protrusions include a first protrusion 23 and a second protrusion 24. The first protrusion 23 and the second protrusion 24 are located on the rotational trajectory of the locking member 3, and at the beginning and end of the range of rotation of the stop surface 321 with the locking member 3, so that the stop surface 321 can abut against the sidewall of the first protrusion 23 or the second protrusion 24. (Combined) Figure 2 and Figure 3 The first protrusion 23 is located at the end of the rotation range of the locking member 3. When the locking member 3 is rotated so that the stop surface 321 abuts against the first protrusion 23, the locking member 3 is locked to the meter body 1. At this time, the first lead seal hole 27 and the second lead seal hole 35 are aligned. The second protrusion 24 is located at the beginning of the rotation range of the locking member 3. When the stop surface 321 on the locking member 3 abuts against the side wall of the second protrusion 24, the locking member 3 is released from the meter body 1. At this time, the first lead seal hole 27 and the second lead seal hole 35 are offset from each other.

[0042] In practice, the first protrusion 23 and the second protrusion 24 can be two block-shaped structures spaced apart. Alternatively, the first protrusion 23 and the second protrusion 24 can be integrally formed, creating two different sidewalls that abut against the locking member 3.

[0043] In this embodiment, a stop surface 321 is formed on the side wall of the head 32. The stop surface 321 is planar.

[0044] Figure 3 As shown, the lead seal groove 21 includes a semi-circular groove and a receiving groove. The semi-circular groove is semi-circular, and the mounting hole 22 is located at the center of the bottom of the semi-circular groove. Figure 4 As shown, the sidewall of the head 32 includes a superior circular arc surface and a stop surface 321 connected sequentially in the circumferential direction. Correspondingly, the rod portion 31 is connected to the center of the superior circular arc surface and passes through the center of the semi-circular groove portion. The diameter of the semi-circular groove portion is larger than the diameter of the superior circular arc surface, so that the head 32 can rotate smoothly in the semi-circular groove portion. One side of the receiving groove portion is connected to the semi-circular opening of the semi-circular groove portion, and the operating member 4 is received in the receiving groove.

[0045] The top surface of the outer cover 2 is provided with locking marks 25 and unlocking marks 26 spaced apart around the outer periphery of the semi-circular groove. The top surface of the head 32 is provided with an indicator mark 322. When the rod 31 is locked to the meter body 1, the indicator mark 322 points to the locking mark 25. The locking member 3 can rotate axially relative to the mounting hole 22 to release the rod 31 from the meter body 1. At this time, the indicator mark 322 switches to point to the unlocking mark 26 as the locking member 3 rotates. In this embodiment, the indicator mark 322 points to the position of the curved surface.

[0046] In other embodiments, the head may also be in the shape of a cylinder, a polygonal cylinder, a semi-cylinder, etc.

[0047] Furthermore, a locking block 34 is provided on the bottom side wall of the locking member 3. The meter body 1 is provided with a locking hole opposite to the mounting hole 22. The locking member 3 is sequentially inserted into the mounting hole 22 and the locking hole. The locking block 34 is offset from the mounting hole 22 and the locking hole. The locking member 3 can rotate relative to the outer cover 2 in the mounting hole 22 so that the locking block 34 can be directly aligned with the mounting hole 22 and the locking hole.

[0048] Specifically, the side wall of the mounting hole 22 is provided with a slot that extends axially through the mounting hole 22. The lock hole on the meter body 1 is located at the bottom of the mounting hole 22 and is opposite to the mounting hole 22. The side wall of the lock hole is provided with a clearance opening, which is directly opposite the slot. In this embodiment, the locking block 34 is provided at the bottom of the side wall of the rod 31. The rod 31 passes through the mounting hole 22 and the lock hole in sequence. The rod 31 can rotate axially relative to the outer cover 2 so that the locking block 34 is vertically directly opposite the slot and the clearance opening, or vertically offset from the slot and the clearance opening.

[0049] In some other embodiments, the locking element 3 may also be a screw with threads on its bottom outer periphery, which can be threaded to the meter body 1.

[0050] The outer cover 2 and the locking member 3 are secured by a lead seal wire 5. In some embodiments, the outer cover 2 has a first lead seal hole 27, and the top of the locking member 3 has a second lead seal hole 35. After rotating the locking member 3 to lock the bottom of the meter body 1, the first lead seal hole 27 and the second lead seal hole 35 face each other, allowing the same lead seal wire 5 to pass through the first lead seal hole 27 and the second lead seal hole 35 in sequence, thus achieving the lead seal securing of the outer cover 2 and the locking member 3. In some embodiments, the operating member 4 can be independent of the lead seal securing structure between the outer cover 2 and the locking member 3, that is, the operating member 4 can be rotated whether the locking member 3 and the meter body 1 are in the lead seal securing state or the lead seal is released.

[0051] In this embodiment, in order to further improve the lead seal protection effect of the smart meter, the top of the outer cover 2, the locking member 3 and the operating member 4 can work together to complete the lead seal fixation.

[0052] Specifically, the lead-sealing groove 21 has two opposite inner sidewalls with first lead-sealing holes 27, which extend to the outer sidewall of the outer cover 2. The top sidewall of the locking member 3 has a through second lead-sealing hole 35. Furthermore, the operating member 4 has a through third lead-sealing hole 42, the axis of which is offset from the rotation axis of the operating member 4. The first lead-sealing hole 27, the second lead-sealing hole 35, and the third lead-sealing hole 42 are arranged opposite each other to allow the same lead-sealing wire 5 to pass through.

[0053] like Figure 1As shown, after the locking member 3 locks the meter body 1 onto the outer cover 2, the second lead-sealing hole 35 of the locking member 3 is aligned with the first lead-sealing hole 27 of the outer cover 2. That is, the two first lead-sealing holes 27 on the inner wall of the lead-sealing groove 21 are respectively aligned with the axial ends of the second lead-sealing hole 35. Next, the operating member 4 is rotated until the third lead-sealing hole 42 is aligned with the second lead-sealing hole 35. A lead-sealing wire 5 can then be threaded between the first lead-sealing hole 27, the second lead-sealing hole 35, and the third lead-sealing hole 42 to complete the lead-sealing installation of the smart meter.

[0054] This application uses locking member 3 and operating member 4 as the lead seal structure. Because the axis of the third lead seal hole 42 is misaligned with the rotation axis of the operating member 4, the lead seal line 5 can restrict the rotation of the operating member 4 relative to the locking member 3 without damaging the lead seal line 5 and the lead seal structure. This further prevents the operating member 4 from rotating relative to the outer cover 2, maintaining the locking member 3 and the meter body 1 locked together, improving the security of the lead seal, and effectively protecting the internal buttons of the smart meter. After the lead seal is released, the operator can control the operating member 4 to flip relative to the locking member 3 into place and push the operating member 4 to achieve the rotation of the locking member 3.

[0055] In fact, one end of the first lead-sealing hole 27 is located on the inner sidewall of the lead-sealing groove 21, and the other end of the first lead-sealing hole 27 can extend to the top surface of the outer cover 2 and be spaced apart from the lead-sealing groove 21 to facilitate the insertion of the lead-sealing line 5. In addition, the end of the first lead-sealing hole 27 away from the lead-sealing groove 21 can also extend to the sidewall of the outer cover 2.

[0056] In this embodiment, the second lead-sealing hole 35 is disposed through the side wall of the head 32 of the locking member 3. Specifically, the second lead-sealing hole 35 penetrates the side wall of the superior arc surface, and the axis of the second lead-sealing hole 35 passes through the center of the arc of the superior arc portion.

[0057] Furthermore, such as Figure 3 As shown, the top surface of the locking member 3 is provided with a receiving notch 36, which extends to the side wall of the locking member 3. The second lead-sealing hole 35 is connected to the receiving notch 36. The extension direction of the receiving notch 36 from the top surface of the locking member 3 to the side wall of the locking member 3 is intersected with the through direction of the second lead-sealing hole 35. That is, the second lead-sealing hole 35 penetrates the two opposite inner side walls of the receiving notch 36, so that the second lead-sealing hole 35 has a multi-segmented channel structure.

[0058] The rotating side of the operating component 4 is rotatably connected to the inner wall of the receiving notch 36. (Connection) Figure 1When the smart meter is in the lead-sealed state, the swing side of the operating member 4 extends toward the side wall of the locking member 3 and passes through the receiving notch 36. The third lead-sealed hole 42 is connected to the receiving notch 36 and is directly opposite the second lead-sealed hole 35 of the locking member 3. That is, the part of the operating member 4 with the third lead-sealed hole 42 is accommodated in the receiving notch 36 so that the lead-sealed wire 5 can pass through the second lead-sealed hole 35 and the third lead-sealed hole 42.

[0059] Furthermore, the swing side of the operating component 4 has a receiving notch 36 for easy operation by the staff. Combined with... Figure 2 When the smart meter is unsealed, the operator can rotate the operating component 4 so that the swing side of the operating component 4 protrudes from the top of the locking component 3, making it convenient for the operator to rotate the locking component 3 through the operating component 4. At this time, the part of the operating component 4 with the third lead seal hole 42 is offset from the second lead seal hole 35 and can be positioned outside the receiving notch 36.

[0060] This application connects one side of the operating member 4 to the inner wall of the receiving notch 36. When the smart meter is in a sealed state, the operating member 4 is embedded between the locking members 3. The sealing line 5 can first pass through one end of the second sealing hole 35 and enter the position of the receiving notch 36. After passing through the third sealing hole 42, it can then pass out of the other end of the second sealing hole 35. This allows the sealing line 5 to pass through the operating member 4 and the locking members 3 in an alternating manner, further increasing the security of the sealing.

[0061] In this embodiment, the receiving notch 36 is provided on the top surface of the head 32 of the locking member 3, the receiving notch 36 extends through to the bottom surface of the head 32, and the receiving notch 36 extends to the outer side wall of the head 32.

[0062] Figure 5 A schematic diagram of the structure of the operating component 4 is shown.

[0063] Reference Figure 5 The operating component 4 includes a toggle block 44 and at least two rotating arms 43. One side of the rotating arm 43 is connected to the toggle block 44, and the other side of the rotating arm 43 is rotatably connected to the locking component 3. The toggle block 44 can swing relative to the locking component 3 to enter or exit the lead seal groove 21.

[0064] The rotating side of the operating element 4 is located on the rotating arm 43, and the swinging side of the operating element 4 is located on the actuating block 44. The operating element 4 is connected to the locking element 3 through at least two rotating arms 43, increasing the rotational connection points of the operating element 4 on the locking element 3 and improving the stability of the operating element 4 relative to the locking element 3 during installation and rotation. The actuating block 44 connects multiple rotating arms 43, making the actuating block 44 and the multiple rotating arms 43 form a whole. When the operating element 4 is flipped up, the actuating block 44 protrudes from the top of the locking element 3. The actuating block 44 can be held by the operator to drive the locking element 3 to rotate within the mounting hole 22.

[0065] Furthermore, at least one rotating arm 43 is provided on each of the opposite sides of the rotation center of the locking member 3. When the operating member 4 is flipped up and the actuating block 44 is twisted, the rotating arms 43 located on both sides of the rotation center of the locking member 3 can jointly drive the locking member 3 to twist, effectively increasing the torque of the locking member 3 and making it easier for the operator to apply force.

[0066] Furthermore, when the actuating block 44 of the operating member 4 is located in the lead seal groove 21, the two opposite inner sidewalls of the lead seal groove 21 stop the actuating block 44 on opposite sides, thereby restricting the actuating block 44 from swinging in the lead seal groove 21, further preventing the operating member 4 from driving the locking member 3 to rotate, and ensuring that the locking member 3 can only be driven to rotate when the operating member 4 rotates to the top of the locking member.

[0067] In this embodiment, the operating member 4 includes two rotating arms 43, which are rod-shaped, and the actuating block 44 is block-shaped and connects the two rotating arms 43.

[0068] like Figure 5 In the specific embodiment shown, the operating member 4 is rotatably connected to the inside of the locking member 3.

[0069] Specifically, one side of the rotating arm 43 is rotatably connected to the inner wall of the receiving notch 36. The rotating arm 43 can be rotated so that the other side of the rotating arm 43 is received in the receiving notch 36 or flipped up relative to the receiving notch 36 and protrudes from the top of the locking member 3. In this embodiment, the third lead-sealing hole 42 is provided on the side wall of the rotating arm 43. In this embodiment, the rotating shaft 41 is provided on the side wall of the rotating arm 43 and is spaced apart from the third lead-sealing hole 42. In this embodiment, the head 32 is provided with two receiving notches 36 spaced apart, the rotating shaft 41 is provided on the side wall of the two rotating arms 43 that are far apart from each other, and the bottom surface of the head 32 is provided with two mounting grooves 33. One end of the mounting groove 33 communicates with a receiving notch 36. After the rotating shaft 41 is locked in the mounting groove 33, the rotating arms 43 can be received in the receiving notches 36 one by one.

[0070] In another embodiment, the operating member 4 may also be rotatably connected to the outer wall of the locking member 3.

[0071] Specifically, a rotating shaft 41 is provided on the side wall of the two rotating arms 43 that are close to each other, and a mounting groove 33 is provided on the head 32 and extends to the outer side wall of the head 32. The rotating shaft 41 is locked in the mounting groove 33, and the two rotating arms 43 are located on opposite sides of the outside of the locking member 3.

[0072] In other embodiments, the operating element 4 may also include one or more rotating arms 43.

[0073] Furthermore, the operating component 4 protrudes on the side away from the locking component 3 in the direction opposite to the locking component 3 to form a paddle 45. When the operating component 4 is located in the lead seal groove 21, there is a gap between the paddle 45 and the bottom of the lead seal groove 21, which makes it easy for the operator to pry the paddle 45 through the gap, thereby prying the operating component 4 relative to the locking component 3, which is convenient for the operator to operate.

[0074] Specifically, the paddle 45 is formed on the actuating block 44, and the swing side of the operating member 4 has a plate-like structure, which makes it easy for the operator to apply force and twist the locking member 3 to rotate.

[0075] In other embodiments, the operating element 4 may also be in the form of a rod, block, sheet, L-shape, or other structures.

[0076] Firstly, the smart meter of this application achieves tool-free installation and removal of the locking member 3 by rotating the operating component 4 onto the locking member 3. This simplifies operation, facilitates force application, and allows workers to quickly install and remove the locking member 3 by hand between the meter body 1 and the outer cover 2, reducing installation and maintenance costs. After the locking member 3 is installed, the operating component 4 can rotate relative to the locking member 3 and be housed within the lead seal groove 21.

[0077] Furthermore, the first lead-sealing hole 27 of the outer cover 2, the second lead-sealing hole 35 at the top of the locking member 3, and the third lead-sealing hole 42 of the operating member 4 can be opposite each other so that the same lead-sealing line 5 can pass through, so that the outer cover 2, the top of the locking member 3, and the operating member 4 can jointly complete the lead-sealing fixation. After the lead-sealing is fixed, the lead-sealing line 5 can restrict the rotation of the operating member 4 relative to the locking member 3, thereby further preventing the operating member 4 from rotating relative to the outer cover 2, keeping the locking member 3 locked to the meter body 1, improving the lead-sealing security, and effectively protecting the device buttons inside the smart meter.

[0078] Furthermore, this application provides a receiving notch 36 on the top surface of the locking member 3, and the second lead seal hole 35 is connected to the receiving notch 36. The operating member 4 is rotatably connected to the inner side wall of the receiving notch 36. When the smart meter is in the lead seal state, the operating member 4 is embedded between the locking members 3, so that the part of the operating member 4 with the third lead seal hole 42 is received in the receiving notch 36, thereby allowing the lead seal line 5 to pass through the operating member 4 and the locking member 3 in an alternating manner, further increasing the lead seal security.

This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.
