Description

Technical Field

[0001] This utility model relates to the field of electricity meter installation technology, specifically an adjustable angle electricity meter mounting and positioning plate. Background Technology

[0002] As the core equipment for electricity metering, the installation accuracy of the electricity meter directly affects the metering accuracy. According to national metrological standards, the tilt angle of the electricity meter should be controlled within 1°. If the tilt exceeds this angle, it may cause uneven force on mechanical parts or electromagnetic field deviation, resulting in metering errors.

[0003] The meter box needs to be fixed to the wall with expansion bolts. However, outdoor walls are often not flat enough due to construction errors, foundation settlement, and long-term exposure to wind, vibration and temperature difference deformation. This makes the fixing structure of the box easy to loosen, causing the internal electricity meter to deviate from the vertical position, especially the phenomenon of tilting in the front and back direction. All of the above problems will affect the meter reading and cause inaccurate measurement.

[0004] Current electricity meters are directly installed on the base plate of the meter box. Traditional meter box base plates use a rigid fixed structure, which cannot be finely adjusted after installation. They require manual disassembly and alignment, which is inefficient and easily damages the wiring terminals. Utility Model Content

[0005] To address the technical problems mentioned above, this utility model provides an adjustable angle energy meter mounting and positioning plate.

[0006] The technical solution of this utility model is as follows:

[0007] An adjustable angle energy meter mounting and positioning plate is set on the bottom plate of the meter box, including a positioning plate body, a rotating shaft is set in the middle of the side of the positioning plate body near the bottom plate in the horizontal direction, and a rotating seat adapted to the rotating shaft is provided on the bottom plate.

[0008] An adjustment unit is provided on the lower part of the base plate near the positioning plate body. The adjustment unit includes a wedge that is adjustable in the vertical direction. The wedge has an adjustment slope. The adjustment slope is inclined from bottom to top towards the base plate. The adjustment slope part abuts against the side of the positioning plate body near the base plate.

[0009] The upper part of the base plate near the positioning plate body is provided with multiple reset units. Each reset unit includes an elastic element whose two ends are respectively connected to the base plate and the positioning plate body.

[0010] The lower part of the base plate is provided with a first connecting piece that connects the base plate and the wedge; the four corners of the positioning plate body are connected to the base plate through connecting units.

[0011] The connecting unit includes connecting bolts located at the four corners of the base plate. The positioning plate body is provided with multiple connecting holes corresponding to the connecting bolts. The positioning plate body is connected to the base plate through a second connecting piece adapted to the connecting bolts.

[0012] The specific structure of the wedge block that can be adjusted in the vertical direction is as follows: the adjustment unit also includes an adjustment seat, on which an adjustment bolt is threadedly connected in the vertical direction. The adjustment bolt passes through the adjustment seat and is rotatably connected to the lower part of the wedge block.

[0013] To facilitate the adjustment of the positioning plate body, the inner diameter of the connecting hole is set to be 0.5-2 mm larger than the outer diameter of the connecting bolt, which facilitates the adjustment of the front and rear tilt angle of the positioning plate body.

[0014] To allow for adjustment of the tilt angle of the positioning plate body in the front and rear directions, the vertical distance between the positioning plate body and the base plate is 0.5-2 cm.

[0015] Furthermore, the elastic element is a compression spring, which is used to support the upper part of the positioning plate body when the wedge moves up and down.

[0016] The specific structure of the first connecting member is as follows: the first connecting member includes an L-shaped plate and a first tightening bolt. The L-shaped plate includes a short plate and a long plate that are vertically connected. The short plate is vertically connected to the adjusting seat. The long plate is parallel to the base plate and is on the outside of the positioning plate body. The first tightening bolt is threadedly connected to the long plate, and one end of the bolt passes through the long plate and is tightened to the outer surface of the positioning plate body.

[0017] To facilitate the stable support and fine-tuning of the positioning plate body by the wedge, the wedge is set horizontally along its length, and the length of the wedge is greater than half of the horizontal length of the positioning plate body.

[0018] To facilitate stable vertical movement of the wedge and enable fine-tuning of the front-to-back angle of the positioning plate body, both the adjusting seat and the wedge are provided with corresponding guide holes in the vertical direction. A guide rod is slidably connected in the guide hole, and one end of the guide rod is connected to the housing of the meter box.

[0019] Preferably, the upper part of the positioning plate body is provided with a threaded hole corresponding to the compression spring, and a limit bolt is connected to the threaded hole. One end of the limit bolt passes through the compression spring and abuts against the inner surface of the base plate. The inner surface of the base plate is the side of the base plate that is close to the positioning plate body.

[0020] The beneficial effects of this utility model are as follows:

[0021] The positioning plate body is installed on one side of the inner surface of the bottom plate of the meter box. The middle part of the positioning plate body is rotatably connected to the rotating seat on the bottom plate through a rotating shaft, so that the upper and lower parts of the positioning plate body can move back and forth. This makes it easy to adjust the positioning plate body to a vertical state according to the tilt angle of the front and rear sides of the positioning plate body, so that the energy meter installed on the positioning plate body remains vertical and can achieve normal metering work.

[0022] The lower part of the positioning plate body is adjusted to be closer to or further away from the base plate by the adjustment unit. Under the action of the rotating shaft, the adjustment unit controls the lower part of the positioning plate body to be closer to the base plate by a certain position, and the upper part of the positioning plate body to be further away from the base plate by a certain distance. The lower part of the positioning plate body is further away from the base plate by a certain position, and the upper part of the positioning plate body is closer to the base plate, which is used to drive the adjustment of the front and rear angle of the energy meter on it.

[0023] The wedge of the adjustment unit can move linearly in the vertical direction. The adjustment slope of the wedge gradually tilts upward, so that when the wedge moves upward, the lower part of the positioning plate body is pushed outward by the wedge and away from the bottom plate. When the wedge moves downward, the lower part of the positioning plate body rotates close to the bottom plate under the action of the compression spring, so that the lower end of the positioning plate body is pressed against the adjustment slope. The positioning plate body is adjusted according to the tilt direction until the positioning plate body is adjusted to the desired position. The position of the positioning plate body is fixed by tightening the first tightening bolt and the second connecting piece.

[0024] When adjusting the positioning plate body, after the tilt angle is detected by external devices such as miniature pendulum inclinometers, laser crosshair projectors or MEMS digital tilt sensors used to detect the tilt of the energy meter or the positioning plate body, the position of the positioning plate body is finely adjusted in the vertical direction by moving the wedge until the positioning plate body is vertical.

[0034] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an adjustable angle electricity meter mounting and positioning plate is set on the base plate 101 of the meter box 1. The base plate 101 is provided with connecting bolts 102 at all four corners. The electricity meter mounting and positioning plate includes a positioning plate body 2. A rotating shaft 3 is set in the middle of the side of the positioning plate body 2 near the base plate 101 along the horizontal direction. The base plate 101 is provided with a rotating seat 4 adapted to the rotating shaft 3. The rotating seat 4 is provided with a rotating groove. The axis of the rotating groove is parallel to the rotating shaft 3. The central angle of the rotating groove is greater than 180°. The rotating shaft 3 is rotatably connected to the rotating seat 4, and the rotating shaft 3 will not detach from the rotating seat 4.

[0035] To allow for adjustment of the tilt angle of the positioning plate body 2 in the front and rear directions, the vertical distance between the positioning plate body 2 and the base plate 101 is 0.5-2 cm.

[0036] The four corners of the positioning plate body 2 are connected to the base plate 101 via connecting units, which include connecting bolts 102 located at the four corners of the base plate 101. The positioning plate body 2 has four connecting holes 201 corresponding to the connecting bolts 102. The positioning plate body 2 is connected to the base plate 101 via second connecting parts 8 adapted to the connecting bolts 102. The second connecting parts 8 can be nuts, which need to be loosened before adjusting the position of the adjustment unit. To facilitate the adjustment of the positioning plate body, the inner diameter of the connecting holes 201 is set to be 0.5-2 mm larger than the outer diameter of the connecting bolts 102, which facilitates the adjustment of the front and rear tilt angle of the positioning plate body 2.

[0037] See Figure 5As shown, an adjustment unit is provided on the lower part of the base plate 101 near the positioning plate body 2. The adjustment unit includes an adjustment seat 9 and a wedge 5 whose position is adjustable in the vertical direction. An adjustment bolt 10 is provided on the adjustment seat 9 in the vertical direction and is threadedly connected to it. The adjustment bolt 10 passes through the adjustment seat 9 and is rotatably connected to the lower part of the wedge 5. A first circular groove 502 is provided on the end of the wedge 5 near the adjustment seat 9 in the vertical direction. A second circular groove 503 is provided on the bottom surface of the first circular groove 502. The size of the second circular groove 503 is larger than the size of the first circular groove 502. The first circular groove 502 and the second circular groove 503 are coaxial. A stop block adapted to the second circular groove 503 is provided on one end of the adjustment bolt 10. The inner diameter of the first circular groove 502 is larger than the outer diameter of the screw of the adjustment bolt 10, so that the adjustment bolt 10 can drive the wedge 5 to move up and down, and the adjustment bolt 10 will not disengage from the wedge 5.

[0038] The wedge 5 has an adjusting slope 501, which is inclined from bottom to top towards the base plate 101. The lower width of the wedge 5 is greater than the upper width, and part of the adjusting slope 501 abuts against the side of the positioning plate body near the base plate 101.

[0039] See Figure 6 As shown, the wedge 5 of the adjustment unit can move linearly in the vertical direction. The adjustment slope 501 of the wedge 5 gradually tilts upward, so that when the wedge 5 moves upward, the lower part of the positioning plate body 2 is pushed outward by the wedge 5 and away from the bottom plate 101. When the wedge 5 moves downward, the lower part of the positioning plate body 2 rotates close to the bottom plate 101 under the action of the compression spring, so that the lower end of the positioning plate body 2 is pressed against the adjustment slope 501. Adjustment is made according to the tilt direction of the positioning plate body 2 until the positioning plate body 2 is adjusted to the desired position. The position of the positioning plate body 2 is fixed by turning the first connecting piece 7 and the second connecting piece 8.

[0040] Three reset units are provided on the upper part of the base plate 101 near the positioning plate body 2. The three reset units are arranged horizontally. Each reset unit includes an elastic element 6 that is connected at both ends to the base plate 101 and the positioning plate body 2, respectively. The elastic element 6 can be a compression spring and can be made of stainless steel. The elastic element 6 can be replaced periodically. The elastic element 6 is used to support the upper part of the positioning plate body 2 when the wedge 5 moves up and down.

[0041] The lower part of the base plate 101 is provided with a first connecting member 7 that connects the base plate 101 and the wedge block 5. Before adjusting the position of the wedge block 5, the first connecting member 7 needs to be loosened. The specific structure of the first connecting member 7 is as follows: the first connecting member 7 includes an L-shaped plate 701 and a first tightening bolt 702. The L-shaped plate 701 includes a short plate and a long plate that are vertically connected. The short plate is vertically connected to the adjusting seat 9. The long plate is parallel to the base plate 101 and is located on the outside of the positioning plate body 2. The first tightening bolt 702 is threadedly connected to the long plate, and one end of the bolt passes through the long plate and is tightened to the outer surface of the positioning plate body 2.

[0042] To facilitate the stable support and fine-tuning of the positioning plate body 2 by the wedge block 5, the length of the wedge block 5 is set horizontally, and the length of the wedge block 5 is greater than half of the horizontal length of the positioning plate body 2.

[0043] To facilitate the stable vertical movement of the wedge 5 and to achieve fine-tuning of the front-to-back angle of the positioning plate body 2, the adjusting seat 9 and the wedge 5 are both provided with corresponding guide holes 11 in the vertical direction. A guide rod 12 is slidably connected in the guide hole 11, and one end of the guide rod 12 is connected to the housing of the meter box 1.

[0044] The upper part of the positioning plate body 2 is provided with a threaded hole 202 corresponding to the compression spring. The threaded hole 202 is internally threaded with a limit bolt 13, and one end of the limit bolt 13 passes through the compression spring and abuts against the inner surface of the base plate 101. After the adjustment unit is adjusted, the first tightening bolt 702 and the second connecting piece 8 are tightened to the appropriate position in sequence, and then the limit bolt 13 is tightened to the appropriate position, so that the end of the limit bolt 13 can abut against the inner surface of the base plate 101. With the cooperation of the first tightening bolt 702 and the second connecting piece 8, the positioning plate body 2 is fixed on the base plate 101.
