Figure 4-6As shown, the quick-release mechanism 5 includes: a fixing rod 51, an inner rod 52 disposed within the fixing rod 51, and an extension plate 57 disposed on the inner wall of the housing 1; the fixing rod 51 has multiple strip-shaped through holes 511, and a snap-fit ​​member 54 is disposed inside it. The snap-fit ​​member 54 can pass through the strip-shaped through holes 511, and the strip-shaped through holes 511 limit and guide the movement direction of the snap-fit ​​member 54; the snap-fit ​​member 54 abuts against the extension plate 57, thereby firmly fixing the upper cover 2 and the housing 1, ensuring that the various components will not loosen due to vibration or external force during normal operation of the energy meter, and maintaining the stability of the energy meter structure; one end of the inner rod 52 is provided with a pressure plate 56, and the other end is connected to a protrusion 55, which can be engaged with a slot 59 disposed on the inner wall of the housing 1; the opening and closing angle of the snap-fit ​​member 54 is controlled by pressing the pressure plate 56; specifically, the operator presses the pressure plate 56 to control the opening and closing angle of the snap-fit ​​member 54.

The circular through hole 58 is adapted to the working size of the guide cylinder 4, providing precise guidance for the installation and positioning of the fixing cylinder 531; the fixing rod 51 is symmetrically provided with positioning members 53 near the pressure plate 56. The positioning members 53 are inserted into the recessed part 521 opened on the inner rod 52. The positioning members 53 are used to limit the inner rod 52; when the inner rod 52 moves to the preset position, the positioning members 53 are inserted into the recessed part 521 to ensure that the inner rod 52 will not slide at will, thereby maintaining the stable state of the quick-release mechanism 5 and ensuring the reliability of the energy meter when it is fixed.

[0034] Figure 7 This is a schematic diagram of the internal structure of a quick-release mechanism for an easily detachable electricity meter disclosed in this utility model; as shown... Figure 7As shown, the snap-fit ​​component 54 includes: a second spring 542, a receiving plate 543 connected to the telescopic end of the second spring 542, and a stop plate 541 hinged to the receiving plate 543; there are multiple stop plates 541, made of high-strength engineering plastic, with preset elasticity, enabling them to flexibly adapt and stably fix under complex working conditions; the stop plate 541 can pass through the strip-shaped through hole 511 and abut against the extension plate 57; one end of the stop plate 541 is hinged to the ear plate 544 provided on the receiving plate 543, ensuring that the stop plate 541 can adapt to different opening and closing angles to better fit and abut against the extension plate 57, and also providing the necessary flexibility and adaptability for the movement of the entire snap-fit ​​component 54 during the quick-release operation; The receiving plate 543 can slide freely along the internal trajectory of the fixing rod 51. As the receiving plate 543 slides, the second spring 542 will compress or extend, thereby changing the contact state between the abutment plate 541 and the extension plate 57. When the receiving plate 543 slides towards the extension plate 57, the second spring 542 returns to its original state, pushing the abutment plate 541 and the extension plate 57 to a tight contact, enhancing the fixing effect. Conversely, when the receiving plate 543 slides in the opposite direction, the second spring 542 is compressed and undergoes elastic deformation. At this time, the receiving plate 543 drives the abutment plate 541 to retract into the fixing rod 51 along the trajectory of the strip-shaped through hole 511 through the ear plate 544, creating conditions for the disassembly of the electricity meter.

[0035] Figure 8 This is an enlarged view of the internal structure of the positioning component of an easily disassembled electricity meter disclosed in this utility model; Figure 9 This is a partial schematic diagram of the inner rod of an easily detachable electricity meter disclosed in this utility model; as shown. Figure 8-9As shown, the positioning component 53 includes: a fixed cylinder 531 disposed on the fixed rod 51 and an insert rod 532 slidably connected to the fixed cylinder 531; the fixed cylinder 531 passes through the fixed rod 51, with small holes on both sides of the top and a hole on the bottom working surface; the bottom working surface of the fixed cylinder 531 is slidably connected to the inner rod 52, which ensures that the movement of the inner rod 52 is not affected by the fixed cylinder 531, and also ensures that the inner rod 52 can move accurately between the two fixed cylinders 531, thus playing a guiding role; a connecting plate 534 is provided inside the fixed cylinder 531, one working surface of the connecting plate 534 is connected to the insert rod 532, and the other working surface is connected to the positioning pin 536, so that the three components can work together. The connecting plate 534 and the positioning pin The positioning pin 536 moves in the direction of movement of the insertion rod 532. The insertion rod 532 is equipped with an elastic ball 533, which engages with the small hole to position the insertion rod 532, preventing it from sliding freely and ensuring the stability of the positioning pin 536. The elastic ball 533 is existing technology and will not be described in detail here. The positioning pin 536 is sleeved with a first spring 535, the telescopic end of which is connected to the connecting plate 534, providing elastic support to the connecting plate 534. The positioning pin 536 passes through the hole and engages with the recess 521, thereby firmly limiting the inner rod 52 and ensuring the stability of the inner rod 52's position during operation, thus ensuring the accuracy and reliability of the entire quick-release operation.

[0036] Working principle: When installing an electricity meter, the operator first inserts the insert plate 21 into the limiting groove 13, initially fixing the upper cover 2 and the housing 1. Then, the operator presses the pressure plate 56, which, through the inner rod 52, drives the receiving plate 543 downward. At this time, the receiving plate 543 is compressed by the second spring 542, causing the abutment plate 541 to retract into the fixing rod 51. Then, the operator passes the fixing rod 51 through the guide tube 4 and inserts it into the extension plate 57 on the upper cover 2 and the housing 1 until the protrusion 55 is embedded in the slot 59. At this time, the operator releases the pressure plate 56, the second spring 542 returns to its original position, and the elastic potential energy pushes the receiving plate 543 to move in the opposite direction, pushing the abutment plate 541 to tightly contact the extension plate 57, thereby fixing the upper cover 2 and the housing 1. Then, the operator presses the insert rod 532 until the elastic ball 533 is inserted into the small hole. At this time, the insert rod 532... The connecting plate 534 drives the positioning pin 536 to insert into the recess 521, thereby fixing the position of the inner rod 52 and realizing the quick installation of the upper cover 2 and the housing 1. Then, the operator manually screws the quick-release screw 7 into the mounting base 6 to realize the quick connection between the tail cover 3 and the wiring assembly 8, thereby completing the installation of the electricity meter. When it is necessary to disassemble the electricity meter, the operator presses the elastic balls 533 on both sides and pulls the plug rod 532 upward. At this time, the positioning pin 536 and the connecting plate 534 follow the plug rod 532 upward until the positioning pin 536 disengages from the recess 521 and enters the fixed cylinder 531. Then, the operator presses the pressure plate 56 in the same way to retract the abutment plate 541 into the fixed rod 51 and pulls the fixed rod 51 out of the upper cover 2. Then, the operator twists the quick-release screw 7 in the opposite direction to separate the tail cover 3 and the wiring assembly 8, thereby completing the disassembly of the electricity meter.
