[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] In the description of this application, it should be understood that the terms "middle," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0028] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0029] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature. Specific implementation method one:
[0031] like Figure 1 and Figure 2 As shown, an electricity meter and its power supply structure include a power supply housing 1 behind the meter, a power supply mounting base 2 that is longitudinally slidably inserted and locked inside the power supply housing 1, and two regulators 3 respectively provided at both ends of the power supply housing 1. The outer ends of the regulators 3 are pushed into and fit against the power supply mounting base 2.
[0032] The working principle and beneficial effects of this embodiment are as follows: The power supply housing 1 is connected to the rear end of the power transformer. The power mounting base 2 is slidably inserted into the power supply housing 1 and locked. The center of the power mounting base 2 is connected to the mounting post through a screw. Two adjusters 3 are adjusted on the power supply housing 1 so that the two adjusters 3 push the two ends of the power mounting base 2 to make arc-shaped adjustment, so that the power mounting base 2 can fit in an arc shape and be used on mounting posts of different shapes. Thus, the power meter can be fully fitted on mounting posts of different shapes.
[0033] This addresses the problem that replacing the battery in an electricity meter requires repeated installation and removal, which is quite cumbersome.
[0034] This solves the problem of the inability to install and fit the meter on different shaped mounting posts, both on-site and outdoors, thus preventing the meter from fitting properly and causing damage due to vibration during outdoor installation. It also effectively saves installation space. Specific Implementation Method Two:
[0036] like Figure 1 — Figure 8 As shown, an electricity meter and its power supply structure are disclosed. The power supply housing 1 of the meter includes a rear housing 4. The outer walls at both ends of the rear housing 4 are provided with side grooves 5. The rear end of the side grooves 5 is provided with side sliding grooves 6 that pass through the rear housing 4 from left to right. The outer wall of the side grooves 5 is provided with side push-lock grooves 7 at the upper end of the side sliding grooves 6. The upper end of the inner wall of the rear housing 4 is provided with a power source conductive plate 8.
[0037] The working principle and beneficial effects of this embodiment are as follows: By setting the rear housing 4 at the rear end of the energy meter, the outer walls at both ends of the rear housing 4 are provided with side grooves 5 and side sliding grooves 6 that run through the rear housing 4 from left to right. The outer wall of the side groove 5 is provided with a side push-lock groove 7 at the upper end of the side sliding groove 6. The side groove 5 is used to limit the use and installation of the regulator 3, and the side sliding groove 6 is used to slide and limit the use and installation of the power supply mounting base 2, while facilitating the replacement of the energy meter's battery. The side push-lock groove 7 is used to lock the power supply mounting base 2 as it slides on the side sliding groove 6. The upper end of the inner wall of the rear housing 4 is provided with a point source conductive plate 8, which is used to electrically connect to the power supply 16 to provide real-time charging power for the energy meter. The upper end of the inner wall of the rear housing 4 is provided with a wire hole for electrically connecting the point source conductive plate 8 to facilitate the passage of connecting wires. Specific implementation method three:
[0039] like Figure 1 — Figure 8 As shown, an electricity meter and its power supply structure are disclosed. The regulator 3 includes an upper push arc rod 9 and a lower push arc rod 10, which are connected by a connecting rack 11. The connecting rack 11 meshes with a gear on a transmission adjustment gear shaft 12, which is rotatably connected in the rear housing 4. The upper push arc rod 9, the lower push arc rod 10, and the connecting rack 11 are all inserted into the side groove 5.
[0040] The working principle and beneficial effects of this embodiment are as follows: the surfaces of the upper push arc rod 9 and the lower push arc rod 10 are both chamfered arc shapes, which facilitates the prevention of damage and interference when pushing the elastic deformation plate 20 of the power supply mounting base 2; by rotating the adjusting gear shaft 12 near the side groove 5, the connecting rack 11 is driven to slide within the side groove 5, thereby pushing the upper push arc rod 9 and the lower push arc rod 10 to slide within the power supply mounting base 2, thereby causing the extended upper push arc rod 9 and the lower push arc rod 10 to deform the elastic deformation plate 20 of the power supply mounting base 2 to fit the shape. Specific implementation method four:
[0042] like Figure 1 — Figure 8As shown, an energy meter and its power supply structure are disclosed. The upper end of the adjusting gear shaft 12 engages with the locking gear seat 13. The locking gear seat 13 is longitudinally inserted into the limiting frame 14, and the limiting frame 14 is fixed to the outer wall of the side end of the rear housing 4.
[0043] The working principle and beneficial effects of this embodiment are as follows: by rotating the adjusting gear shaft 12, the upper pushing arc rod 9 and the lower pushing arc rod 10 are pushed and retracted. By pressing down the locking gear seat 13 within the limiting frame 14, the locking gear seat 13 is engaged and locked to the adjusting gear shaft 12, thereby locking the adjusting gear shaft 12 and preventing loosening caused by force contraction and retraction. Specific implementation method five:
[0045] like Figure 1 — Figure 8 As shown, an electricity meter and its power supply structure are disclosed. The power supply mounting base 2 includes a power supply slide 15, in which a power supply 16 is disposed. Two side slide rods 17 are fixed at both ends of the power supply slide 15. The power supply slide 15 is slidably inserted into the side slide groove 6 through the two side slide rods 17. A central hanging plate 18 is fixed at the center of the rear end of the power supply slide 15. Two ends of the central hanging plate 18 are respectively hinged to elastic deformation plates 20 through short shafts. The side slide rods 17 are connected to the screws on the locking push plate 19 by bolts. The locking push plate 19 is pushed into the side push lock groove 7 by threaded engagement. The upper and lower ends of the elastic deformation plate 20 respectively abut against the upper push arc rod 9 and the lower push arc rod 10. The elastic deformation plate 20 is provided with multiple threaded holes for installation at corresponding positions.
[0046] The working principle and beneficial effects of this embodiment are as follows: By adding the power slide 15 of the power mounting base 2 into the side slide groove 6 of the rear shell base 4, and combining the addition by longitudinally limiting the sliding of two side slide rods 17 in the side slide groove 6, the power supply 16 is provided in the power slide 15 so that the power supply 16 can be used to supply and display power. The center hanging plate 18 at the rear end of the power slide 15 is fixed to the designated position of the mounting column by bolts. Then, by adjusting the adjusting gear shaft 12 of the adjuster 3, the upper pushing arc rod 9 and the lower pushing arc rod 10 are pushed into the elastic deformation plate 20 hinged at both ends of the center hanging plate 18, so that the elastic deformation plate 20 can deform and fit against the mounting column. After locking, the fitting installation of different shapes of outdoor mounting columns is completed, thereby solving the problem of vibration damage during outdoor installation.
[0047] The elastic deformation plate 20 is provided with multiple threaded holes for installation at corresponding positions, which facilitates connection and fixation in the lateral direction. Specific implementation method six:
[0049] An electricity meter, wherein a power supply housing 1 is provided at the rear end of the electricity meter.
[0050] The working principle and beneficial effects of this embodiment are as follows: by installing and adapting the power supply housing 1 behind the meter to the rear end of the electricity meter, it adapts to the corresponding power supply structure and solves the problems encountered in the outdoor installation and use of electricity transformers.
