Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] AsFigures 1-8 As shown in the figure, an embodiment of an electricity meter case that is easy to disassemble and assemble is provided in this embodiment.

[0028] An electricity meter case that is easy to disassemble and assemble includes a lower case 1 and an upper case 2. A plurality of flip covers 3 are movably installed on the upper case 2. A connection structure 4 is provided on the lower case 1. The connection structure 4 includes a plurality of first fixing blocks 5 fixedly installed inside the upper case 2. A plurality of first mounting holes 6 are formed in the first fixing blocks 5. A first spring 7 is fixedly installed inside the first mounting holes 6. One end of the first spring 7 is fixedly installed with a first locking block 8. A plurality of connection frames 9 that cooperate with the first fixing blocks 5 are fixedly installed inside the lower case 1. A plurality of first locking holes 10 that are adapted to the first locking blocks 8 are formed in the connection frames 9. Through the setting of the connection structure 4, the traditional method of using bolts and nuts to fix the connection between the lower case 1 and the upper case 2 is changed. Thus, there is no need to specially prepare specific tools, such as screwdrivers, wrenches, etc., to install and disassemble the lower case 1 and the upper case 2. When connecting the lower case 1 and the upper case 2, first align the first fixing blocks 5 on the upper case 2 with the positions of the connection frames 9 on the lower case 1, and then splice the lower case 1 and the upper case 2. During the splicing process, the first locking blocks 8 will be squeezed and contracted into the first mounting holes 6. When the first locking blocks 8 move to the positions of the first locking holes 10, the first locking blocks 8 can pop out under the elastic action of the first springs 7 and be clamped inside the first locking holes 10, so as to fix the first fixing blocks 5 inside the connection frames 9, and thus complete the splicing of the lower case 1 and the upper case 2. Correspondingly, since both sides of the first locking blocks 8 are arranged in an arc shape, when disassembling the lower case 1 and the upper case 2, directly pulling the upper case 2 can cause the first locking blocks 8 to be squeezed and contracted, so as to complete the disassembly of the lower case 1 and the upper case 2. The advantage of this structure is that there is no need for the complexity of installation and the need for professional tools. At the same time, the disassembly process does not require loosening bolts or nuts one by one, thus saving time, and during the disassembly process, damage to the case or internal components caused by violent means can be avoided.

[0029] As Figure 5 and Figure 6 shown, a plurality of limiting rods 11 are fixedly installed at the bottom of the upper case 2. A plurality of limiting holes 12 that are adapted to the limiting rods 11 are formed in the lower case 1. Through the setting of the limiting rods 11 and the limiting holes 12, when the lower case 1 and the upper case 2 are spliced, the plurality of limiting rods 11 at the bottom of the upper case 2 can be inserted into the plurality of limiting holes 12 in the lower case 1, which can improve the installation stability of the lower case 1 and the upper case 2 and avoid the situation that the lower case 1 and the upper case 2 are separated when the lower case 1 is collided.

[0030] As Figure 5As shown, a plurality of heat dissipation holes 13 are formed in the upper housing 2, and a dust-proof plate 14 connected to the upper housing 2 is arranged inside the heat dissipation holes 13. Through the arrangement of the heat dissipation holes 13 and the dust-proof plate 14, the heat inside the upper housing 2 can be dissipated, avoiding the failure of the electric energy meter caused by excessive internal temperature. At the same time, the dust-proof plate 14 can prevent dust from entering the inside of the upper housing 2 through the heat dissipation holes 13, preventing dust from accumulating inside the upper housing 2 and causing poor contact of the electric energy meter.

[0031] As Figure 5 shown, a first magnetic ring 15 is fixedly installed inside the dust-proof plate 14, and a second magnetic ring 16 magnetically connected to the first magnetic ring 15 is fixedly installed on the upper housing 2. Through the arrangement of the first magnetic ring 15 and the second magnetic ring 16, after the two attract each other, the dust-proof plate 14 can be fixed on the inner wall of the upper housing 2 to prevent it from falling off. Due to the characteristics of the first magnetic ring 15 and the second magnetic ring 16, the dust-proof plate 14 can be removed by directly pulling it, so as to facilitate the disassembly and replacement of the dust-proof plate 14 when it is damaged.

[0032] As Figure 8 shown, a second fixing block 17 is fixedly installed at the bottom of the flip cover 3. A plurality of second mounting holes 18 are formed in the second fixing block 17. A second spring 19 is fixedly installed inside the second mounting holes 18. One end of the second spring 19 is fixedly installed with a second clamping block 20. A plurality of fixing plates 21 are fixedly installed on the upper housing 2. The fixing plates 21 are provided with second clamping holes 22 for cooperating with the second clamping block 20. Through the arrangement of the second fixing block 17, the second mounting holes 18, the second spring 19, the second clamping block 20, the fixing plates 21 and the second clamping holes 22, when the flip cover 3 is covered on the upper housing 2, the second fixing block 17 will be inserted between the fixing plates 21, and at the same time, the second clamping block 20 will be compressed and retracted into the inside of the second mounting holes 18. When the second clamping block 20 moves to the position of the second clamping hole 22, the second clamping block 20 can pop out under the elastic action of the second spring 19 and be clamped inside the second clamping hole 22, so as to improve the stability of the flip cover 3 covered on the upper housing 2.

[0033] As Figure 8 shown, a rounded edge 23 is arranged on one side of the second clamping hole 22, and one end of the second clamping block 20 is set to be arc-shaped. Through the arrangement of the rounded edge 23 and the arc shape, the friction force at one end of the second clamping block 20 can be reduced, and at the same time, the design of the rounded edge 23 can also reduce the friction force on its surface, so that the second clamping block 20 can slide more smoothly on the fixing plate 21, which can not only reduce the wear between the fixing plate 21 and the second clamping block 20, but also make it more labor-saving for personnel to open and close the flip cover 3.

[0034] As Figure 1 and Figure 2As shown, a display screen 24 is provided at the top of the upper housing 2. A plurality of query buttons 25 are installed on one side of the display screen 24. Through the settings of the display screen 24 and the query buttons 25, various information can be displayed on the display screen 24, such as total power consumption, power consumption at each rate, time, etc. This enables personnel to observe conveniently and make effective adjustments in a timely manner when a failure occurs. The query buttons 25 enable personnel to query the detailed conditions of the electricity meter, such as usage date, usage time, electricity meter reading, electricity price per unit, electricity fee balance, etc.

[0035] In this embodiment, as Figures 1-8 shown, the working process of an easily disassembled and assembled electricity meter housing provided in this embodiment is as follows:

[0036] When connecting the lower housing 1 and the upper housing 2, first align the first fixing block 5 on the upper housing 2 with the position of the connection frame 9 on the lower housing 1, and then splice the lower housing 1 and the upper housing 2. During the splicing process, the first clamping block 8 will be squeezed and contracted into the interior of the first mounting hole 6. When the first clamping block 8 moves to the position of the first clamping hole 10, the first clamping block 8 can pop out under the elastic action of the first spring 7 and be clamped inside the first clamping hole 10, so that the first fixing block 5 can be fixed inside the connection frame 9, and thus the splicing of the lower housing 1 and the upper housing 2 can be completed. Correspondingly, since both sides of the first clamping block 8 are provided with arc shapes, when disassembling the lower housing 1 and the upper housing 2, directly pulling the upper housing 2 can cause the first clamping block 8 to be squeezed and contracted, and thus the disassembly of the lower housing 1 and the upper housing 2 can be completed.
