Detailed implementation manners

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] As Figures 1 - 10 shown, an embodiment of a split-type electric energy meter case is provided in this embodiment.

[0030] A split-type electric energy meter case includes a case main body 1 and an upper case 2. A cover plate 3 is installed on the top of the upper case 2. A splicing structure 4 is arranged on the upper case 2. The splicing structure 4 includes a plurality of fixed columns 5 fixedly installed at the bottom of the upper case 2. A plurality of installation holes 6 are formed in the fixed columns 5. A spring 7 is fixedly installed inside the installation hole 6. One end of the spring 7 is fixedly installed with a clamping block 8. A plurality of fixed sleeves 9 are fixedly installed inside the case main body 1. A plurality of clamping holes adapted to the clamping blocks 8 are formed inside the fixed sleeves 9. A plurality of clamping sleeves 10 are fixedly installed on the upper case 2. A plurality of buckles 11 adapted to the clamping sleeves 10 are fixedly installed inside the case main body 1. Through the setting of the splicing structure 4, the traditional design of the case main body 1 as an integral type is changed, so that the case main body 1 and the upper case 2 can be spliced. While integrating measurement modules, display modules, communication modules, etc. in one case, it is also convenient to install the case in a narrow space. When the case main body 1 and the upper case 2 are spliced, first buckle the clamping sleeve 10 on the buckle 11, and then align the fixed column 5 with the fixed sleeve 9 and insert it. During the process of inserting the fixed column 5 into the fixed sleeve 9, the clamping block 8 will be squeezed and contracted into the installation hole 6. When the clamping block 8 moves to the clamping hole formed on the fixed sleeve 9, the clamping block 8 can pop out under the elastic action of the spring 7 and be clamped inside the clamping hole, so as to fix the fixed column 5 inside the fixed sleeve 9, and the splicing of the case main body 1 and the upper case 2 can be completed. When pulling the upper case 2, the clamping block 8 will be squeezed and contracted into the installation hole 6. When the clamping block 8 disengages from the clamping hole, the fixed column 5 can be pulled out of the fixed sleeve 9. When the fixed column 5 is pulled out, the clamping sleeve 10 can be removed from the buckle 11 to complete the disassembly of the case main body 1 and the upper case 2. The advantage of this structure is that the installation efficiency of the case main body 1 and the upper case 2 is greatly improved. And when a certain module such as a measurement chip is damaged, there is no need to disassemble the entire case for maintenance, reducing the maintenance time and cost. In this way, the difficulty of installation, maintenance and upgrade is greatly reduced.

[0031] As Figure 3 and Figure 5As shown, the opening of the fixed sleeve 9 is provided with rounded edges, and one end of the clamping block 8 is provided with an arc. Through the settings of the rounded edges and the arc, the frictions at the port of the fixed sleeve 9 and one end of the clamping block 8 can be greatly reduced, making the sliding of the clamping block 8 smoother. Therefore, not only can the wear of the clamping block 8 and the fixed sleeve 9 be reduced, but also it is more labor-saving for personnel to disassemble and install the watch case body 1 and the upper case 2.

[0032] As Figure 4 and Figure 6 shown, a plurality of air inlet holes 12 are provided on one side of the watch case body 1, and a plurality of heat dissipation holes 13 are provided on the other side of the watch case body 1. An exhaust fan 14 connected to the watch case body 1 is fixedly installed inside the heat dissipation hole 13. Through the settings of the air inlet holes 12, the heat dissipation holes 13 and the exhaust fan 14, the outside air can circulate inside the watch case body 1, thereby dissipating heat from the electronic components inside the watch case body 1. The design of the exhaust fan 14 can accelerate the speed of heat dissipation from the inside of the watch case body 1, and the gas circulation can also prevent the humidity inside the watch case body 1 from increasing and causing the electronic components to get damp.

[0033] As Figure 6 shown, a dust-proof cover 15 is provided inside the air inlet hole 12. A first magnetic ring 16 is fixedly installed on the watch case body 1, and a second magnetic ring 17 magnetically connected to the first magnetic ring 16 is fixedly installed inside the dust-proof cover 15. Through the settings of the dust-proof cover 15, the first magnetic ring 16 and the second magnetic ring 17, the dust-proof cover 15 can be fixed on the watch case body 1 to prevent it from falling off when the first magnetic ring 16 and the second magnetic ring 17 are adsorbed. The dust-proof cover 15 can isolate dust or sundries outside when the air inlet hole 12 intakes air, preventing dust from entering the inside of the watch case body 1 through the air inlet hole 12 and affecting the electronic components. Due to the characteristics of the first magnetic ring 16 and the second magnetic ring 17, the dust-proof cover 15 can be disassembled by directly pulling it, which is convenient for personnel to disassemble and replace the dust-proof cover 15 when it is damaged.

[0034] As Figure 7 and Figure 8 shown, a plurality of notches are provided at the bottom of the cover plate 3. A plurality of first magnetic blocks 18 are fixedly installed inside the notches. A plurality of insertion blocks 19 adapted to the notches are fixedly installed on the upper case 2. A plurality of second magnetic blocks 20 magnetically connected to the first magnetic blocks 18 are fixedly installed at both ends of the insertion blocks 19. Through the settings of the notches, the first magnetic blocks 18, the insertion blocks 19 and the second magnetic blocks 20, after the notches provided at the bottom of the cover plate 3 are aligned with the insertion blocks 19 and inserted, the plurality of first magnetic blocks 18 on the cover plate 3 can be adsorbed to the second magnetic blocks 20 on both sides of the insertion blocks 19, thereby fixing the cover plate 3 on the upper case 2. Correspondingly, the cover plate 3 can be opened by directly pulling it, which is convenient for personnel to open the cover plate 3 to repair the electronic components inside the watch case body 1.

[0035] AsFigure 9 and Figure 10 As shown in Figure 10 , a limiting plate 21 is fixedly installed at the bottom of the upper case 2, and a limiting hole 22 adapted to the limiting plate 21 is provided on the main case body 1. Through the arrangement of the limiting plate 21 and the limiting hole 22, after inserting the limiting plate 21 at the bottom of the upper case 2 into the interior of the limiting hole 22, the splicing of the main case body 1 and the upper case 2 can be further limited, thereby making the connection between the two more stable.

[0036] As Figure 10 shown in Figure 10 , an installation groove 23 is provided at the bottom of the main case body 1, and a plurality of telescopic bolts 24 are provided on the main case body 1. Through the arrangement of the installation groove 23 and the telescopic bolts 24, the main case body 1 can be conveniently hung on the wall. When the main case body 1 is suspended, the telescopic bolts 24 will be squeezed and contracted by the installation plate on the wall. When the installation plate is engaged inside the installation groove 23, the telescopic bolts 24 will pop out to further fix the installation plate, thereby improving the stability of the installation of the main case body 1.

[0037] In this embodiment, as Figures 1 - 10 shown in Figures 1 - 10 , the working process of a split-type electric energy meter case provided in this embodiment is as follows:

[0038] When the main case body 1 and the upper case 2 are spliced, first, the card sleeve 10 is buckled on the buckle 11, and then the fixing column 5 is aligned with the fixing sleeve 9 and inserted. During the process of inserting the fixing column 5 into the fixing sleeve 9, the clamping block 8 will be squeezed and contracted into the installation hole 6. When the clamping block 8 moves to the clamping hole provided on the fixing sleeve 9, the clamping block 8 can pop out under the elastic action of the spring 7 and be engaged in the clamping hole, thereby fixing the fixing column 5 inside the fixing sleeve 9, and the splicing of the main case body 1 and the upper case 2 can be completed. When the upper case 2 is pulled, the clamping block 8 will be squeezed and contracted into the installation hole 6. When the clamping block 8 disengages from the clamping hole, the fixing column 5 can be pulled out of the fixing sleeve 9. When the fixing column 5 is pulled out, the card sleeve 10 is removed from the buckle 11, and the disassembly of the main case body 1 and the upper case 2 can be completed.
