Specific implementation

[0022] In order to more clearly and completely explain the technical scheme of the utility model, the utility model will be further explained below in combination with the drawings. Embodiment

[0023] As Figures 1-4 shown, an embodiment of the utility model proposes an electric meter convenient to overhaul, which is mainly composed of mounting box body 1 and buckle cover 2. The inside of mounting box body 1 is installed with circuit board 3, which is used for realizing the main function of the electric meter. In order to facilitate the overhaul and maintenance of the electric meter, the application specially designs a dismounting assembly, which comprises U-shaped plate 4 fixedly installed at the side of mounting box body 1 and connecting frame 5 fixedly installed at the opening end surface of buckle cover 2. The both ends of U-shaped plate 4 are throughly provided with limiting slot 6, and these limiting slots are used for cooperating with limiting insert plate 12 on connecting frame 5, so as to realize the stable connection of buckle cover 2 and mounting box body 1. Lap plate 11 is slidably connected at the inner wall of connecting frame 5, limiting insert plate 12 is fixedly connected to the surface of the end wall of connecting frame 5, when buckle cover 2 is covered on mounting box body 1, limiting insert plate 12 will be inserted into limiting slot 6, so as to realize the preliminary fixing. In addition, reciprocating component is further connected between connecting frame 5 and lap plate 11, which is used for assisting the insertion and extraction operation of limiting insert plate 12. At the same time, resisting structure is further connected between buckle cover 2 and circuit board 3, which is used for ensuring the stable position of circuit board 3 in mounting box body 1, preventing it from shaking when working.

[0024] Further, the reciprocating component comprises a strip-shaped recess 7 formed in the inner side wall of the connecting frame 5, two end walls of the strip-shaped recess 7 are fixedly connected with a horizontal fixing rod 8, the outer periphery of the horizontal fixing rod 8 is sleeved with a spring 9, and the spring 9 provides elastic force for reciprocating movement. The outer periphery of the horizontal fixing rod 8 is slidably sleeved with a moving sleeve block 10, and the moving sleeve block 10 can reciprocate on the horizontal fixing rod 8 under the action of the spring 9. When it is needed to open the buckling cover 2, the moving sleeve block 10 can be manually pushed to drive the overlapping plate 11 and the limiting plug 12 to move, so as to be pulled out of the limiting insertion slot 6. After being loosened, the elastic force of the spring 9 can reset the moving sleeve block 10 to drive the limiting plug 12 to be reinserted into the limiting insertion slot 6; the design of the reciprocating component makes the disassembly and assembly of the buckling cover 2 more convenient and fast, and improves the maintenance efficiency of the electric meter.

[0025] Further, the resisting structure comprises a resisting rod 13 fixedly connected to the inner top wall of the buckling cover 2 and a sleeving cylinder 14 fixedly connected to the surface of the circuit board 3. When the buckling cover 2 is covered on the mounting box body 1, the lower end of the resisting rod 13 is inserted into the inner wall of the sleeving cylinder 14 and contacts the surface of the circuit board 3, so as to realize the fixation of the circuit board 3. This design is not only simple and effective, but also can ensure the stable position of the circuit board 3 in the mounting box body 1 and prevent the circuit board 3 from shaking during work; the design of the resisting structure improves the stability of the circuit board 3 and guarantees the working performance and reliability of the electric meter.

[0026] Further, the moving sleeve block 10 is slidably connected at the inner wall of the strip-shaped recess 7, which ensures the stable sliding of the moving sleeve block 10 on the horizontal fixing rod 8. Meanwhile, the opposite surfaces of the two moving sleeve blocks 10 are fixedly connected with the two end surfaces of the overlapping plate 11, so that when the moving sleeve block 10 slides on the horizontal fixing rod 8, the overlapping plate 11 and the limiting plug 12 are driven to move together to realize the insertion and pulling-out operation of the limiting plug 12; the fixed connection of the moving sleeve block 10 and the overlapping plate 11 ensures the cooperative work of the disassembly and assembly component and improves the disassembly and assembly efficiency of the electric meter.

[0027] Further, one end of the limiting plug 12 is inserted into the inner wall of the limiting insertion slot 6, and the opening size of the limiting insertion slot 6 and the design size of the limiting plug 12 are adapted to each other. This design ensures that the limiting plug 12 can be stably inserted into the limiting insertion slot 6 to realize the firm connection of the buckling cover 2 and the mounting box body 1. Meanwhile, it is also convenient to pull out the limiting plug 12 by pushing the moving sleeve block 10 when needed to realize the disassembly of the buckling cover 2; the adaptive design of the limiting plug 12 and the limiting insertion slot 6 improves the connection stability and disassembly and assembly convenience of the electric meter.

[0028] Further, one end of the spring 9 is fixedly connected to the end wall of the strip-shaped groove 7, and the other end is fixedly connected to the end surface of the moving sleeve block 10. This design ensures that the spring 9 can provide stable elastic support for the reciprocating movement of the moving sleeve block 10. When the moving sleeve block 10 is pushed, the spring 9 will be compressed; when the moving sleeve block 10 is released, the elastic force of the spring 9 will reset the moving sleeve block 10, driving the limiting insertion plate 12 to reinsert into the limiting insertion slot 6; the fixed connection of the spring 9 provides reliable elastic support for the reciprocating movement of the disassembly component, improving the disassembly efficiency and convenience of the electric meter.
