Description

Technical Field

[0001] The present disclosure relates to the technical field of electric meters, and in particular to an electric energy meter. Background Art

[0002] Traditional electricity meters are typically mounted on a wall using mounting holes on the back of the meter box. For example, a three-point mounting system secures the meter to the wall or inside a meter box using a single mounting hole at the top and two mounting holes at the bottom of the meter box. This ensures that the mounting holes are fixed relative to the meter box and located within the meter body, preventing adjustment during installation. Because the top mounting hole cannot extend beyond the meter body, this approach cannot meet the diverse market demands for larger installation dimensions.

[0003] Existing electricity meters have additional mounting brackets, which can increase the installation size to meet diverse market requirements. However, these brackets require separate packaging and are complex to install during transportation. Once installed, these brackets extend outside the meter, increasing packaging space and costs. Utility Model Content

[0004] Based on this, in order to solve the above problems, it is necessary to provide an electric energy meter.

[0005] An embodiment of the present disclosure provides an electric energy meter, which includes a shell and a hanging bracket. A hanging slot and a matching structure are provided on the back of the shell. The hanging slot is located at the upper end of the shell, and at least one first hanging hole is provided on the top wall of the hanging slot. The hanging bracket includes a hanging portion and an installation portion. The hanging bracket has a received state and an assembled state. In the received state, the hanging bracket is detachably connected to the matching structure. In the assembled state, the installation portion cooperates with the hanging slot and at least part of the hanging portion protrudes from the shell.

[0006] The electric energy meter provided by the disclosed embodiments has a hanging bracket that can be detachably connected to a mating structure when housed. When the hanging bracket is adapted to the mating structure, it is located inside the housing and can be packaged and transported together with the housing, reducing packaging space and costs while also preventing the hanging bracket from being lost during separate transportation. When needed, the hanging bracket is removed from the mating structure and inserted into the hanging slot so that the second hanging hole extends out of the housing, thereby increasing the installation dimensions in the assembled state and meeting diverse market requirements for installation dimensions. If the installation requirements are met solely by relying on the first hanging hole of the housing, the hanging bracket can be omitted or located inside the housing. This solution simplifies the structure and saves costs.

[0007] In some embodiments, the mounting portion includes a deformable clamping portion; in the assembled state, the clamping portion is clamped to the first hanging hole.

[0008] With this arrangement, the clamping portion deforms to facilitate entry into the first hanging hole and is thus clamped in the first hanging hole, making the connection structure in the assembled state simple, the connection firm, and the repeated disassembly of the clamping portion and the first hook convenient.

[0009] In some embodiments, a second hanging hole is provided on the hanging portion, and in the assembled state, the second hanging hole protrudes from the housing.

[0010] With such arrangement, the second hanging hole facilitates the installation of the electric energy meter with the outside world, and the second hanging hole protruding from the shell can increase the installation size of the electric energy meter, meeting the market's diverse demands for installation size.

[0011] In some embodiments, the matching structure includes a combination slot and a mounting rod at the top. When the hanging tab is in the accommodated state, the hanging tab is located inside the combination slot and the clamping portion is clamped to the mounting rod.

[0012] With this arrangement, the hanging bracket is located inside the combination slot in the stored state, saving packaging space. The clamping portion is clamped to the mounting rod to improve the stability and firmness of the hanging bracket in the combination slot, preventing the hanging bracket from falling out of the combination slot and being lost when the energy meter is transported or moved.

[0013] In some embodiments, the clamping portion is an elastic part, and the clamping portion can move along the thickness direction; when the clamping portion is subjected to a force along the thickness direction, the hanging bracket can be detachably installed on the shell; when the clamping portion is subjected to a force perpendicular to the thickness direction, the mounting rod and the first hanging hole can prevent the hanging bracket from being separated from the shell.

[0014] This arrangement ensures the secureness and stability of the mounting bracket during use, as the mounting bracket is constantly subject to forces perpendicular to the thickness of the bracket after installation, preventing it from separating from the housing. Forces applied along the thickness of the bracket facilitate its removal from the housing, making installation simple, time-saving, and labor-saving.

[0015] In some embodiments, the clamping portion is a protrusion, the mounting portion further includes a fixing portion, the first end of the protrusion is connected to the fixing portion, the second end of the protrusion extends toward the clamping portion, and there is a gap between the second end of the protrusion and the hanging portion.

[0016] With such arrangement, the protrusion can be easily pressed in the thickness direction to generate deformation, and the gap is used for clamping the mounting rod or the first hanging hole.

[0017] In some embodiments, the protrusion is arranged obliquely, the second end is higher than the first end along the thickness direction, and the second end is flush with the hanging portion.

[0018] Because the protrusion is set at an angle and the second end is higher than the first end, the second end is more likely to bounce back and return to a state flush with the hanging part after being pressed in the thickness direction. The second end is not easy to deform along the thickness direction after being clamped, thereby ensuring the reliability and stability of the connection.

[0019] In some embodiments, the combination groove includes a first groove and a second groove connected to each other, the bottom wall of the first groove and the bottom wall of the second groove are in the same plane, the mounting rod is located at the top of the first groove, the distance between the bottom wall of the mounting rod and the bottom wall of the first groove is smaller than the distance between the top of the protrusion and the bottom wall of the first groove, and the width of the mounting rod is smaller than the width of the gap; the first groove, the second groove and the mounting rod are used to accommodate and clamp the hanging climb.

[0020] With this arrangement, the first groove accommodates the mounting portion, the second groove accommodates the hook portion, and the mounting rod secures the hook in place in the combined groove. The first, second, and mounting rods ensure the hook remains stable in position when engaged and does not extend above the housing, facilitating packaging and transportation of the entire meter.

[0021] In some embodiments, the combination groove also includes a third groove connected to the second groove, the second groove is located between the first groove and the third groove, the shape of the third groove is the same as the shape of the hanging part, the depth of the third groove is greater than the thickness of the hanging part, and the depth of the third groove is less than the depth of the second groove; the second groove and the third groove are used to accommodate and remove the hanging rope.

[0022] The protrusion is no longer clamped on the mounting rod after being subjected to a force in the thickness direction, and then the hanging bracket is able to move in the combined groove when subjected to a force perpendicular to the thickness direction. The provision of the third groove facilitates the movement and removal of the hanging bracket.

[0023] In some embodiments, the top wall of the hanging groove is provided with two first hanging holes, which are arranged side by side in the vertical direction. When the hanging bracket is in the assembled state, the clamping portion is clamped in the upper first hanging hole.

[0024] The multiple hanging holes on the top wall of the hanging slot reduce the installation dimensions of the electricity meter. The clipping portion, which snaps into the first hanging hole on the upper side, further increases the installation dimensions of the electricity meter, meeting the diverse market demands for installation dimensions. The small dimensions of the mounting and clipping portions of the hanging bracket enable the clipping portion to snap into the first hanging hole on the upper side, saving costs and facilitating installation and transportation.

[0038] refer to Figure 1 , Figure 1 The overall structure of the electric energy meter 100 when the hanging bracket 2 in the embodiment of the present disclosure is in an assembled state is shown. The present disclosure relates to the technical field of electric energy meters.

[0039] Combine Figures 2 to 6, an embodiment of the present disclosure provides an electric energy meter 100. The electric energy meter 100 includes a shell 1 and a hanging bracket 2. The back of the shell 1 is provided with a hanging slot 11 and a matching structure 12. The hanging slot 11 is located at the upper end of the shell 1. The top wall of the hanging slot 11 is provided with at least one first hanging hole 111. The hanging bracket 2 includes a hanging portion 21 and a mounting portion 22. The hanging bracket 2 has a receiving state and an assembly state. In the receiving state, the hanging bracket 2 is detachably connected to the matching structure 12. Exemplarily, the hanging portion 21 and the mounting portion 22 are both accommodated in the matching structure 12. In the assembled state, the mounting portion 22 is matched with the hanging slot 11 and at least part of the hanging portion 21 protrudes from the shell 1.

[0040] The electric energy meter 100 provided in the disclosed embodiment is in a retracted state when not in use, and the hanging bracket 2 can be positioned within the housing 1 via the mating structure 12. When the installation dimensions of the electric energy meter 100 are larger, the hanging bracket 2 can be removed from the mating structure and installed in the hanging slot 11, so that the hanging portion 21 protrudes from the housing 1, increasing the installation dimensions of the electric energy meter 100. If the installation requirements are met solely by the first hanging hole 111 of the housing 1, the hanging bracket 2 can be omitted. This solution is simple in structure, easy to disassemble, and saves costs.

[0041] In addition, when the hanging rack 2 is in the retracted state, it can be packaged and transported together with the shell 1, reducing packaging space and cost, and avoiding the loss of the hanging rack 2 during separate transportation; the change of the state of the hanging rack 2 can meet the market's diverse demands for installation dimensions.

[0042] For example, the housing 1 of the energy meter 100 has an internal storage space. The housing 1 includes a front and a back. The back of the meter 100 is designed to contact a wall for mounting on a wall or elsewhere. The housing 1 of the energy meter 100 has a hanging slot 11 in the center of the top and two mounting holes near the sides of the bottom. This creates a triangle when installed, which improves the stability of the meter 100.

[0043] For example, the hanging slot 11 is in the shape of a rectangular parallelepiped. The hanging slot 11 extends vertically and opens upward. The mounting portion 22 of the hanging tab 2 can enter the hanging slot 11 from top to bottom, so that at least a portion of the hanging portion 21 is located on the upper side of the housing 1. For example, the hanging portion 21 completely protrudes from the housing 1 and is located on the upper side of the housing 1, or the portion of the hanging portion 21 that can be mounted externally protrudes from the housing 1 and is located on the upper side of the housing 1.

[0044] For example, the mating structure 12 is arranged parallel to the hanging slot 11 and extends in the same direction as the hanging slot 11. The mating structure 12 is arranged in the vertical direction. In other embodiments, the mating structure 12 is arranged perpendicular to the hanging slot 11 and extends in a direction perpendicular to the direction of the hanging slot 11. That is, the mating structure 12 is arranged in the left-right direction.

[0045] refer to Figure 1 and Figure 2 In some embodiments, the mounting portion 22 includes a deformable engaging portion 221; in the assembled state, the engaging portion 221 engages with the first hanging hole 111. This configuration allows the engaging portion 221 to deform and enter the first hanging hole 111, thereby engaging with the first hanging hole 111. This simplifies the connection structure in the assembled state, provides a secure connection, and facilitates repeated removal of the engaging portion 221 from the first hook.

[0046] For example, the first hanging hole 111 is a gourd hole. The clamping portion 221 is clamped in the gourd hole and the upper end of the clamping portion 221 abuts against the small hole on the upper part of the gourd hole, making the installation more secure and not easy to shake.

[0047] refer to Figure 1 and Figure 6 In some embodiments, the top wall of the hanging groove 11 is provided with two first hanging holes 111, which are arranged side by side in the vertical direction. When the hanging bracket 2 is in the assembled state, the clamping portion 221 is clamped into the upper first hanging hole 111. The provision of multiple hanging holes on the top wall of the hanging groove 11 can reduce the installation size of the electric energy meter 100. The clamping portion 221 being clamped into the upper first hanging hole 111 further increases the installation size of the electric energy meter 100, meeting the diverse market demands for installation size. The small size of the mounting portion 22 and the clamping portion 221 of the hanging bracket 2 enables the clamping portion 221 to be clamped into the upper first hanging hole 111. The design of the hanging bracket 2 saves costs and facilitates installation and transportation.

[0048] In other embodiments, the top wall of the hanging groove 11 may be provided with three, four or even more first hanging holes 111 along the vertical direction. When the hanging bracket 2 is in the assembled state, the engaging portion 221 is engaged with the upper first hanging hole 111 .

[0049] refer to Figure 1 and Figure 5 In some embodiments, the attachment portion 21 is provided with a second hanging hole 211. In the assembled state, the second hanging hole 211 protrudes from the housing 1. This arrangement facilitates the installation of the energy meter 100 with respect to the outside world. The protrusion of the second hanging hole 211 from the housing 1 can increase the installation size of the energy meter 100, thereby meeting the diverse market requirements for installation size.

[0050] Exemplarily, the size and shape of the second hanging hole 211 are the same as those of the first hanging hole 111, facilitating installation and positioning of the energy meter 100. For example, the second hanging hole 211 is also a gourd-shaped hole. In other embodiments, the shapes of the first hanging hole 111 and the second hanging hole 211 may differ.

[0051] refer to Figure 3 、 Figure 4 and Figure 6In some embodiments, the mating structure 12 includes a combination slot 121 and a mounting rod 122 at the top. When the hanging bracket 2 is in the stored state, the hanging bracket 2 is located within the combination slot 121, and the engaging portion 221 engages with the mounting rod 122. This arrangement allows the hanging bracket 2 to be located within the combination slot 121 when stored, saving packaging space. The engaging portion 221 engages with the mounting rod 122, improving the stability and firmness of the hanging bracket 2 in the combination slot 121 and preventing the hanging bracket 2 from falling out of the combination slot 121 and being lost during transportation or movement of the energy meter 100.

[0052] refer to Figures 1 to 6 In some embodiments, the engaging portion 221 is a protrusion, and the combination slot 121 includes a first groove 1211 and a second groove 1212 connected to each other. The bottom walls of the first groove 1211 and the second groove 1212 are coplanar. The mounting rod 122 is located at the top of the first groove 1211. The distance between the bottom wall of the mounting rod 122 and the bottom wall of the first groove 1211 is less than the distance between the top of the protrusion and the bottom wall of the first groove 1211. The width of the mounting rod 122 is less than the width of the gap 23. The first groove 1211, the second groove 1212, and the mounting rod 122 are used to accommodate and engage the hanging bracket 2. In this configuration, the first groove 1211 is used to accommodate the mounting portion 22, the second groove 1212 is used to accommodate the hanging portion 21, and the mounting rod 122 is used to secure the hanging bracket 2 in the combination slot 121. The first groove 1211 , the second groove 1212 and the mounting rod 122 ensure the position stability of the hanging bracket 2 in the mating state and ensure that the hanging bracket 2 is not higher than the housing 1 , which facilitates the packaging and transportation of the entire electric energy meter 100 .

[0053] refer to Figures 1 to 6 In some embodiments, the combination slot 121 further includes a third slot 1213 connected to the second slot 1212. The second slot 1212 is located between the first slot 1211 and the third slot 1213. The third slot 1213 has the same shape as the hook portion 21. The depth of the third slot 1213 is greater than the thickness of the hook portion 21, but less than the depth of the second slot 1212. The second and third slots 1212 and 1213 are used to accommodate and remove the hanging tab 2. When a force along the thickness direction is applied to the protrusion, it is no longer engaged with the mounting rod 122. Subsequently, the hanging tab 2 can be moved within the combination slot 121 under a force perpendicular to the thickness direction. The provision of the third slot 1213 facilitates the movement and removal of the hanging tab 2.

[0054] Exemplarily, the combination slot 121 has openings facing rearward and upward, and includes a first groove 1211, a second groove 1212, and a third groove 1213, connected in sequence in the vertical direction. The mounting rod 122 is connected to the sidewall of the first groove 1211 near the second groove 1212 in the horizontal direction. The hook portion 21 of the hanging bracket 2 slides from top to bottom along the upper opening to the second groove 1212, so that the mounting portion 22 is located within the first groove 1211 and the protrusion is higher than the surface of the mounting rod 122 in the thickness direction but lower than the surface of the housing 1, thereby engaging with the mounting rod 122 and stopping sliding. When the protrusion deforms and becomes lower than the surface of the mounting rod 122 in the thickness direction, the hanging bracket 2 continues to move downward, with the hook portion 21 located in the third groove 1213 and the mounting portion 22 located in the second groove 1212, thereby facilitating the removal of the hanging bracket 2.

[0055] refer to Figures 1 to 5 In some embodiments, the clamping portion 221 is an elastic member capable of moving along the thickness direction. When the clamping portion 221 is subjected to a force along the thickness direction, the hanging bracket 2 is removably mounted on the housing 1. When the clamping portion 221 is subjected to a force perpendicular to the thickness direction, the mounting rod 122 and the first hanging hole 111 prevent the hanging bracket 2 from separating from the housing 1. This arrangement ensures the secureness and stability of the hanging bracket 2 during use after installation, as the hanging bracket 2 is constantly subjected to forces perpendicular to the thickness direction after installation, preventing separation from the housing 1. Forces along the thickness direction facilitate removal of the hanging bracket 2 from the housing 1, simplifying installation and saving time and effort.

[0056] For example, the clamping portion 221 in the accommodated state is subjected to a force toward the front, and the clamping portion 221 is deformed toward the front, so that the clamping portion 221 is lower than the surface of the mounting rod 122, and the hanging bracket 2 can move up and down so that the hanging bracket 2 is finally separated from the shell 1.

[0057] For example, the clamping portion 221 in the installed state is subjected to a force toward the front, and the clamping portion 221 is deformed toward the front, so that the clamping portion 221 is lower than the surface of the top wall of the hanging groove 11, and the hanging rack 2 can move up and down so that the hanging rack 2 is finally separated from the shell 1.

[0058] refer to Figure 5 In some embodiments, the mounting portion 22 further includes a fixing portion 222. The protruding first end 2211 is connected to the fixing portion 222, and the protruding second end 2212 extends toward the engaging portion 221. A gap 23 is defined between the protruding second end 2212 and the engaging portion 21. This arrangement facilitates deformation of the protrusion by compression along the thickness direction, and the gap 23 is used to engage the mounting rod 122 or the first hanging hole 111.

[0059] Exemplarily, the fixing portion 222 is square, the first end 2211 of the protrusion is connected to one end of the fixing portion 222 corresponding to the hanging portion 21, and the fixing portion 222 forms a space. After the protrusion is subjected to a force along the thickness direction, it can be accommodated in the space formed by the fixing portion 222.

[0060] For example, the mounting rod 122 can be snapped into the gap 23. The distance between the gourd hole of the first hanging hole 111 and the upper side of the hanging groove 11 is smaller than the gap 23, so as to facilitate the snapping of the protrusion.

[0061] refer to Figures 1 to 5 In some embodiments, the protrusion is tilted, the second end 2212 is higher than the first end 2211 in the thickness direction, and the second end 2212 is flush with the hanging portion 21. Because the protrusion is tilted and the second end 2212 is higher than the first end 2211, the second end 2212 is more likely to bounce back and return to a flush position with the hanging portion 21 after being pressed in the thickness direction. After the second end 2212 is engaged, it is unlikely to deform in the thickness direction, thereby ensuring the reliability and stability of the connection.

[0062] Exemplarily, the first end 2211 is arranged parallel to the surface of the housing 1 and has a shorter extension than the second end 2212. The upper surface of the second end 2212 is an arc surface, which is convenient for snapping into the first hanging hole 111.

[0063] For example, the steps for using the hanging bracket 2 are as follows: the hook portion 21 moves downward from the first groove 1211 to the second groove 1212, and the mounting portion 22 simultaneously moves into the first groove 1211 so that the mounting rod 122 engages with the gap 23. Due to the engagement between the hook portion 21 and the protrusion, the hanging bracket 2 cannot move vertically, and the hanging bracket 2 is completely accommodated in the housing 1, making it easy to transport. When the hanging bracket 2 is needed, the protrusion is pressed toward the front of the housing 1 so that the protrusion is lower than the surface of the mounting rod 122. The hanging bracket 2 then moves downward as a whole until the hook portion 21 is located in the third groove 1213 and the mounting portion 22 is located in the second groove 1212, and the hanging bracket 2 is then removed. Turn the hanging rack 2 upside down, and install the mounting portion 22 into the hanging groove 11 from the top down, with the protrusion facing the rear side. At this time, the second end 2212 of the protrusion is subjected to a force toward the front of the shell 1 until the protrusion enters the first hanging hole 111 and then elastically deforms so that the second end 2212 restores its original height and is thus clamped in the first hanging hole 111. At this time, the hanging portion 21 is located above the shell 1 to expand the installation size, and the second hanging hole 211 thus meets the installation size of the electric energy meter 100, facilitating the installation of the electric energy meter 100.

To make the description concise, not all possible combinations of the various technical features in the above embodiments are described.
