[0003] An investigation revealed that a Chinese utility model patent (publication number: CN214150832U) discloses a multi-functional power meter that is easy to install. The meter includes an "L"-shaped mounting bracket and a meter body. Two fixing blocks are symmetrically arranged on the "L"-shaped mounting bracket, forming a mounting cavity for the meter body. Each fixing block has a sliding wedge-shaped adjusting block inside. The inclined surface of the wedge-shaped adjusting block has a groove. One end of a locking block is movably engaged in the groove and connected to the wedge-shaped adjusting block, while the other end passes through a through-groove and is movably connected to a slot on the side wall of the meter body. A connecting piece is fixed to the bottom of the wedge-shaped adjusting block. One end of a movable arm is rotatably mounted on the connecting piece via a rotating shaft, and the other end is connected to a movable arm via a rotating shaft.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides an instrument, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the easy-to-install multi-functional power meter includes a mounting plate 1, a first mounting rod 2 fixedly mounted on the mounting plate 1, a second mounting rod 3 fixedly mounted on the mounting plate 1, a meter body 4 disposed on one side of the mounting plate 1, a fixed frame 5 fixedly mounted on the meter body 4, movable plates 6 fixedly mounted on both sides of the fixed frame 5, and a control mechanism disposed inside the movable plate 6 for facilitating the movement of the meter body 4.

[0027] The control mechanism includes a limiting block 7 slidably installed inside the movable plate 6, a rotating rod 8 rotatably installed inside the movable plate 6 via a rotating shaft, a pressing block 9 slidably installed inside the movable plate 6, a guide post 10 fixedly installed on the pressing block 9, and a limiting groove 11 opened inside the movable plate 6 for the guide post 10 to slide. The movable plate 6 is slidably installed on the first mounting rod 2 and the second mounting rod 3.

[0028] The limiting block 7 passes through the movable plate 6, and one end of the two rotating rods 8 is hinged to both sides of the limiting block 7, while the other end of the two rotating rods 8 is hinged to one side of the pressing block 9.

[0029] When using this easy-to-install multi-functional power meter, first install the mounting plate 1 in a suitable position. Then, align the two through slots on the movable plate 6 with the first mounting rod 2 and the second mounting rod 3, allowing the meter body 4 to slide along the direction of the first mounting rod 2 and the second mounting rod 3. By manually pressing the pressing block 9 upward, the pressing block 9 moves upward, driving the guide column 10 to move along the limiting groove 11, thus limiting the movement of the pressing block 9. The movement of the pressing block 9 drives the rotating rod 8 to rotate around the rotating axis inside the movable plate 6. Since the other end of the rotating rod 8 is hinged to the limiting block 7, the rotating rod 8 drives the limiting block 7 to move downward simultaneously, so that the limiting block 7 no longer contacts the first mounting rod 2, thus reaching the limit. At this time, the meter body 4 can slide along the first mounting rod 2 and the second mounting rod 3, which facilitates the effective dissipation of heat generated by the meter body 4 during use. If the meter body 4 is damaged, there is more space for repair, reducing resource waste.

[0030] Furthermore, in order to re-secure the instrument body 4 after it has been moved, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first spring 12 is provided inside the movable plate 6. One end of the first spring 12 is fixedly connected to the inner wall of the movable plate 6, and the other end of the first spring 12 is fixedly connected to the top of the pressing block 9.

[0031] The movable plate 6 is equipped with a second spring 13. One end of the second spring 13 is fixedly connected to the bottom of the limiting block 7, and the other end of the second spring 13 is fixedly connected to the top of the pressing block 9.

[0032] When using this easy-to-install multi-functional power meter, if it is necessary to move the meter body 4, the pressing block 9 is manually pressed upwards. During the movement of the pressing block 9, the two first springs 12 are compressed. As the pressing block 9 moves upwards and the limiting block 7 moves downwards synchronously through the control mechanism, the second spring 13 is compressed. After the meter body 4 is moved to the appropriate position, the pressing block 9 is released. The elastic potential energy of the first spring 12 and the second spring 13 causes the pressing block 9 to move downwards until the pressing block 9 returns to its initial position. At the same time, the second spring 13 pushes the limiting block 7 upwards until the limiting block 7 returns to its initial position and contacts the bottom of the first mounting rod 2 again, thus completing the fixing and limiting.

[0033] It should be noted that, in order to prevent the instrument body 4 from moving off the first mounting rod 2 and the second mounting rod 3, such as Figure 1 , Figure 2 and Figure 5 As shown, one end of the second mounting rod 3 is rotatably connected to a rotating wheel 14, and a stop rod 15 is fixedly connected to the side surface of the rotating wheel 14. The end of the stop rod 15 away from the rotating wheel 14 is threaded.

[0034] A rotating block 16 is screwed onto the side surface of the stop bar 15. The rotating block 16 has a threaded hole inside, and the mounting plate 1 has multiple mounting holes 17 inside.

[0035] When using this easy-to-install multi-functional power meter, the mounting plate 1 is installed in a suitable position through the mounting hole 17. Then, by aligning the two through slots on the movable plate 6 with the first mounting rod 2 and the second mounting rod 3, the meter body 4 can slide along the direction of the first mounting rod 2 and the second mounting rod 3. Then, by manually rotating the stop bar 15 upwards until it reaches the inside of the first mounting rod 2, the rotating block 16 is moved downwards along the stop bar 15 by manually rotating it until the bottom of the rotating block 16 contacts the top of the first mounting rod 2, blocking the gap between the first mounting rod 2 and the second mounting rod 3.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
