[0028] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0029] See Figures 1 to 7 This invention provides an electrical quantity measuring device for medium-voltage electrical equipment, comprising a measuring device body 1, with slots 2 on both sides of the measuring device body 1; two rotating legs 3, which are rotatably connected to both sides of the measuring device body 1 via rotating shafts, with sliding grooves 4 on the rear side of each rotating leg 3 and movable grooves 5 on the front side of each rotating leg 3; wherein a fixing mechanism 6 is provided inside the movable groove 5; and two telescopic legs 7, which are respectively disposed inside the sliding grooves 4, with support feet 8 rotatably connected to the rear side of each telescopic leg 7 via rotating shafts.

[0030] Anti-slip pads are fixedly connected to both sides of the bottom rear side of the measuring device body 1. There are several slots 2, which are evenly distributed on both sides of the measuring device body 1. The sliding groove 4 is connected to the movable groove 5.

[0031] Limiting blocks 15 are fixedly connected to the top of the front and rear sides of the telescopic outrigger 7. The side of the limiting block 15 closest to the inner wall of the slide 4 contacts the inner wall of the slide 4. A cavity 10 is provided inside the telescopic outrigger 7. A clamping mechanism 11 that works with the fixing mechanism 6 is provided inside the cavity 10.

[0032] A fixing hole 12 is provided on the side of the cavity 10 away from the measuring device body 1, which is used in conjunction with the clamping mechanism 11. There are several fixing holes 12, which are evenly distributed on the side of the cavity 10 away from the measuring device body 1.

[0033] By using the measuring device body 1, rotating support leg 3, telescopic support leg 7, and support foot 8 in combination, the problem of existing electrical quantity measuring equipment being prone to movement during use, causing the connecting wires to be dragged and resulting in poor contact at the line connection points is solved.

[0034] In use, rotate the rotating leg 3 to a suitable angle, then fix the rotating leg 3 by operating the fixing mechanism 6. Operate the clamping mechanism 11 and extend the telescopic leg 7 to the required position. Then, operate the clamping mechanism 11 to fix the telescopic leg 7. Rotate the foot 8 to make the anti-slip pad on the foot 8 contact the placement platform. If the placement platform is made of ferrous metal, the magnet 14 will adhere to the placement platform, thus fixing the position of the measuring device body 1 and completing the use.

[0035] Example 2

[0036] Based on the above embodiments, the following settings are also made:

[0037] Please see Figure 4 and Figure 5 The fixing mechanism 6 includes a first spring 601. A movable plate 602 is fixedly connected to the side of the first spring 601 near the measuring device body 1. A locking block 603 is fixedly connected to the side of the movable plate 602 away from the first spring 601. The side of the locking block 603 near the slot 2 passes through the rotating adjustment block and extends into the inside of the slot 2. A pressing block 604 is fixedly connected to the rear side of the movable plate 602 near the first spring 601. The side of the pressing block 604 away from the movable plate 602 passes through the rotating support leg 3 and extends to the outside of the rotating support leg 3.

[0038] The side of the first spring 601 away from the movable plate 602 is fixedly connected to the inner wall of the movable groove 5. The side of the locking block 603 close to the inner wall of the locking groove 2 is in contact with the inner wall of the locking groove 2. The top and bottom of the movable plate 602 are rotatably connected to the inner wall of the movable groove 5 through a rotating shaft. Sliding holes 9 are respectively opened on both sides of the movable groove 5 to cooperate with the locking block 603 and the pressing block 604.

[0039] The push plate 606 is in contact with the inner wall of the groove 605 on the side closest to the inner wall of the groove 605. The positioning block 607 is in contact with the inner wall of the movable groove 5 on the side closest to the inner wall of the movable groove 5. A protrusion 16 that works with the slide rail 608 is fixedly connected to the top of the sliding hole 9 on the side furthest from the measuring device body 1. There are three protrusions 16, which are distributed in a stepped manner on the top of the sliding hole 9 on the side furthest from the measuring device body 1.

[0040] By setting the fixing mechanism 6, the rotating support leg 3 can be positioned, making it convenient for the user to adjust the pitch angle of the measuring device body 1 for easy use. By setting the first spring 601, the movable plate 602 can be reset. By setting the locking block 603 and the locking groove 2, the rotating support leg 3 can be fixed. By setting the movable plate 602, the locking block 603 can be moved, allowing the locking block 603 to be pulled out from the inside of the locking groove 2. By setting the sliding hole 9, the locking block 603 and the pressing block 604 can be moved easily. By setting the pressing block 604, the push plate 606 can be moved. By setting the push plate 606, the movable plate 602 can be rotated. By setting the positioning block 607, the pressing block 604 can be limited. By setting the protrusion 16 and the slide 608, the movement of the pressing block 604 can be restricted.

[0041] In use, press the pressing block 604. The pressing block 604 pushes the movable plate 602 to rotate through the push plate 606, causing the movable plate 602 to squeeze the first spring 601 and drive the locking block 603 to be pulled out from the inside of the slot 2. Rotate the rotating support leg 3 until it rotates to the appropriate position. Then release the pressing block 604. The force released after the first spring 601 is squeezed pushes the movable plate 602 to rotate in the opposite direction and enter the inside of the slot 2. At the same time, the movable plate 602 pushes the pressing block 604 to reset through the push plate 606, thus completing the adjustment.

[0042] Example 3

[0043] Based on the above embodiments, the following settings are also made:

[0044] Please see Figure 4 and Figure 6 The clamping mechanism 11 includes a connecting plate 1101. The front side of the connecting plate 1101 extends into the interior of the movable groove 5. A fixing block 1102 is fixedly connected to the front side of the connecting plate 1101 away from the measuring device body 1. The side of the fixing block 1102 away from the connecting plate 1101 extends into the interior of the fixing hole 12. A positioning post 1103 is provided on the front side of the connecting plate 1101 near the measuring device body 1. A second spring 1104 is sleeved on the surface of the positioning post 1103. The side of the connecting plate 1101 near the positioning post 1103 is sleeved on the surface of the positioning post 1103.

[0045] The side of the connecting plate 1101 closest to the inner wall of the cavity 10 contacts the inner wall of the cavity 10. The front side of the right side of the connecting plate 1101 contacts the movable plate 602. The side of the fixing block 1102 closest to the inner wall of the fixing hole 12 contacts the inner wall of the fixing hole 12. The side of the positioning column 1103 closest to the measuring device body 1 is fixedly connected to the inside of the movable groove 5. The two sides of the second spring 1104 are fixedly connected to the inner wall of the movable groove and the connecting plate 1101, respectively.

[0046] By setting the clamping mechanism 11, the telescopic outrigger 7 can be fixed, making it convenient to use the adjusted telescopic outrigger 7. By setting the connecting plate 1101, the fixing block 1102 can be pulled out from the inside of the fixing hole 12. By setting the fixing block 1102 to the fixing hole 12, the telescopic outrigger 7 can be fixed. By setting the second spring 1104, the connecting plate 1101 can be reset. By setting the positioning post 1103, the connecting plate 1101 can be positioned.

[0047] In use, the user pulls the pressing block 604, which slides in the inner cavity of the sliding hole 9. At the same time, the rear protrusion 16 enters the inner cavity of the slide rail 608, causing the push plate 606 to be pulled out from the inner cavity of the groove 605. Pressing the pressing block 604 pushes the connecting plate 1101 to slide on the surface of the positioning post 1103 through the push plate 606. While squeezing the second spring 1104, the connecting plate 1101 drives the fixing block 1102 to be pulled out from the inner cavity of the fixing hole 12. Pulling the telescopic support leg 7 moves it to the appropriate length. Then, the user releases the pressing block 604. The force released after the second spring 1104 is squeezed pushes the connecting plate 1101 to slide in the opposite direction on the surface of the positioning post 1103, and drives the fixing block 1102 into the inner cavity of the fixing hole 12, thus completing the use.

[0048] Working principle of the invention:

[0049] When adjusting the rotating support leg 3, pull the pressing block 604 so that the front protrusion 16 enters the inner cavity of the slide 608. Then press the pressing block 604. The pressing block 604 pushes the movable plate 602 to rotate through the push plate 606. This causes the movable plate 602 to squeeze the first spring 601 and pull the locking block 603 out of the slot 2. Rotate the rotating support leg 3 to the appropriate position. Then release the pressing block 604. The force released after the first spring 601 is squeezed pushes the movable plate 602 to rotate in the opposite direction and enter the slot 2. At the same time, the movable plate 602 pushes the pressing block 604 to reset through the push plate 606, thus completing the adjustment.

[0050] When adjusting the telescopic support leg 7, the user pulls the pressing block 604, which slides in the inner cavity of the sliding hole 9. At the same time, the rear protrusion 16 enters the inner cavity of the slide rail 608, causing the push plate 606 to be pulled out from the inner cavity of the groove 605. Pressing the pressing block 604 pushes the connecting plate 1101 to slide on the surface of the positioning post 1103 through the push plate 606. While squeezing the second spring 1104, the connecting plate 1101 drives the fixing block 1102 to be pulled out from the inner cavity of the fixing hole 12. Pulling the telescopic support leg 7, the user moves the telescopic support leg 7 to the appropriate length. Then, the user releases the pressing block 604. The force released after the second spring 1104 is squeezed pushes the connecting plate 1101 to slide in the opposite direction on the surface of the positioning post 1103. At the same time, the fixing block 1102 enters the inner cavity of the fixing hole 12, and the connecting plate 1101 pushes the push plate 606 to move in the opposite direction and reset, thus completing the use.

[0051] When the rotating support leg 3 and the telescopic support leg 7 are adjusted simultaneously, pulling the pressing block 604 causes the middle side protrusion 16 to slide into the inner cavity of the slide rail 608. Pressing the pressing block 604 simultaneously pushes the movable plate 602 and the connecting plate 1101 through the push plate 606. When the push plate 606 pushes the connecting plate 602 to rotate, it causes the movable plate 602 to squeeze the first spring 601 and simultaneously causes the locking block 603 to be pulled out from the inside of the locking groove 2. At the same time, the push plate 606 pushes the connecting plate 1101 to slide on the surface of the positioning post 1103 and squeezes the second spring 1104. Simultaneously, the connecting plate 1101 drives the fixing block. 1102 is pulled out from the inner cavity of the fixing hole, the rotating support leg 3 is rotated to the appropriate position, and the telescopic support leg 7 is pulled to the appropriate length. Then, the pressing block 604 is released. The force released after the first spring 601 is squeezed pushes the movable plate 602 to rotate in the opposite direction and enter the slot 2. At the same time, the force released after the second spring 1104 is squeezed pushes the connecting plate 1101 to slide in the opposite direction on the surface of the positioning post 1103. At the same time, the fixing block 1102 enters the inner cavity of the fixing hole 12. The movable plate 602 and the connecting plate 1101 push the push plate 606 to move in the opposite direction and reset.

[0052] Rotate the support leg 8 so that the anti-slip pad on the support leg 8 contacts the placement platform. If the placement platform is made of ferrous metal, the magnet 14 will adhere to the placement platform, thus fixing the position of the measuring device body 1 and completing the use.

[0053] In summary, this electrical quantity measuring device for medium-voltage electrical equipment, through the coordinated use of the measuring device body 1, rotating support leg 3, telescopic support leg 7, and support foot 8, solves the problems of existing electrical quantity measuring devices being prone to movement during use, causing dragging of connecting cables and resulting in poor contact at the line connection points. Furthermore, due to the different heights of operators and the different operating angles when operators are standing or sitting, the electrical quantity measuring device cannot be specifically adjusted according to the suitability of the operator.

[0054] The beneficial effects of this invention are as follows:

[0055] 1. This invention solves the problem that existing electrical quantity measuring equipment is prone to movement during use, causing the connecting wires to be dragged and resulting in poor contact at the wiring connection. Furthermore, due to the different heights of operators and the different operating angles when standing or sitting, the electrical quantity measuring equipment cannot be specifically adjusted according to the operator's suitability. This is achieved by setting up a measuring device body, a rotating support leg, a telescopic support leg, and a support foot in coordination. Pressing the pressing block pushes the movable plate to rotate, causing the movable plate to squeeze the first spring and drive the locking block to be pulled out from the inside of the locking slot. Rotating the rotating support leg solves the problem that existing electrical quantity measuring equipment is prone to movement during use, causing the connecting wires to be dragged and resulting in poor contact at the wiring connection. In addition, because the operating angles of operators are different when standing and sitting, the electrical quantity measuring equipment cannot be specifically adjusted according to the operator's suitability.

[0056] 2. By setting anti-slip pads, the present invention can increase the friction between the measuring device body and the table surface, making the measuring device less prone to movement.

[0057] 3. By setting a fixing mechanism, the present invention can position the rotating support leg, making it convenient for the user to adjust the pitch angle of the measuring device body, thus facilitating the use of the measuring device body.

[0058] 4. The present invention can reset the movable plate by setting the first spring, fix the rotating support leg by setting the locking block and the locking groove, drive the locking block to move by setting the movable plate, so that the locking block can be pulled out from the inside of the locking groove, and facilitate the movement of the locking block and the pressing block by setting the sliding hole.

[0059] 5. The present invention can push the push plate to move by setting a pressing block, push the movable plate to rotate by setting a push plate, limit the pressing block by setting a positioning block, and restrict the movement of the pressing block by setting a protrusion and a slide.

[0060] 6. By setting telescopic outriggers, the present invention can increase the pitch angle of the measuring device body, so as to facilitate the use of the measuring device body by the staff when standing.

[0061] 7. The present invention, by setting a clamping mechanism, can fix the telescopic outrigger, making it convenient to use the adjusted telescopic outrigger.

[0062] 8. By setting a connecting plate, the present invention can drive the fixing block to be pulled out from the inside of the fixing hole. By setting the fixing block to the fixing hole, the telescopic outrigger can be fixed. By setting a second spring, the connecting plate can be reset. By setting a positioning post, the connecting plate can be positioned.

[0063] 9. By setting support legs, the present invention can increase the contact area between the adjustable support legs and the table surface. By setting anti-slip pads, the friction between the support legs and the table surface can be enhanced. By setting magnets, when the table surface is made of ferrous metal, the support legs can be positioned and the anti-slip pads can make the support legs difficult to move.
