[0001] The present application relates to the technical field of electric energy meter boxes, and in particular to electric shock-proof safe electric energy meter boxes. Background Art

[0002] The electric energy meter box is a combination of metering instruments and auxiliary equipment necessary for measuring electric energy, which mainly includes electric energy meters, voltage and current transformers for measurement and their secondary circuits, electric energy metering panels, cabinets, boxes, etc.

[0003] The box body of the existing metal energy meter box is generally made of metal material to adapt to different environments. However, corresponding insulation protection should be made in the box to avoid electric shock. As described in the patent with application number CN202320227596.3, an insulating protective shell is installed in the box, and the insulating protective shell is fixedly installed in the box. Electronic components are installed in the insulating protective shell, and the installation position of the electronic components is difficult to adjust. When the electronic components in the energy meter box are working, they will emit heat. When the box body is dissipating heat, the insulating protective shell has a certain barrier effect, and the heat dissipation effect of the box body needs to be improved. Summary of the invention

[0004] In order to facilitate heat dissipation of electronic components in an electric energy meter box and to flexibly adjust their positions, the present application provides an electric shock-proof safe electric energy meter box.

[0006] By adopting the above technical solution, the meter box isolates the internal electronic components from the box body through the insulating mounting frame, which effectively prevents the risk of electric shock. At the same time, the spherical structure on the heat sink is used to increase the heat dissipation area and improve the heat dissipation efficiency. The adjacent spherical structures are in a tangent state and the height positions of the centers of the two adjacent rows of spheres are different. The side walls of the box body are provided with heat dissipation grooves to facilitate the heat exchange between the air inside the box and the external air. If wind or dust enters the box body through the heat dissipation grooves of the box body, the spherical structures on the two rows of mounting rods are tangent, and the spherical structures are staggered with each other. The heat sink can not only dissipate heat for the electronic components on the mounting seat, but also have a barrier effect. In addition, the spherical structure can also slide on the mounting rod and be limited by the pressure block. This design allows the spherical structure to slide and be fixed on the mounting rod. Installation The seat provides a stable installation foundation through the fixed connection between the mounting ring and the mounting plate; the design of the perforation and the give way groove enables the mounting seat to fit closely with the spherical structure on the heat sink to ensure the stable installation of the connector; the linkage rod connects the mounting rods in the same row and allows them to slide relative to the base plate. This design allows the heat sink to be adjusted as needed to adapt to different working environments or heat dissipation requirements, and when the spherical structures of the two rows of mounting rods are tangent, the two rows of spherical structures limit each other, so that the mounting seat is stably installed on the heat sink, and when the linkage rod carries one row of mounting rods away from the other row of mounting rods, the abutment block is rotated to leave the spherical structure, the spherical structure can be moved, and the installation position of the mounting seat can be adjusted, so that the electronic components can be installed on the insulating mounting frame, which is convenient for heat dissipation and can flexibly adjust its own position.

[0007] Optionally, a groove is formed on a side wall of the mounting plate close to the mounting ring.

[0011] Optionally, the support rod includes a first support half ring and a second support half ring, the first support half ring is fixedly mounted on the base plate, and the second support half ring is rotatably mounted on the first support half ring.

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1 -Attached Fig. 9 This application is described in further detail.

[0019] The embodiment of the present application discloses an anti-electric shock safety electric energy meter box. Figure 1 The electric shock-proof safety energy meter box includes a box body 100, an insulating mounting frame 200 installed in the box body 100, and the mounting frame 200 includes a bottom plate 210 and a top plate 220, and a heat sink 230 installed between the bottom plate 210 and the top plate 220. A mounting seat 300 for mounting electronic components is installed on the heat sink 230. There is a gap between the bottom plate 210, the top plate 220, the heat sink 230 and the inner wall of the box body 100. The bottom plate 210 and the inner bottom wall of the box body 100 are connected with a support rod 240. There are multiple support rods 240, so that the mounting frame 200 can be stably installed in the box body 100. When the electronic components are installed on the heat sink 230 through the mounting seat 300, the heat sink 230 can achieve a good heat dissipation effect when the electronic components are working.

[0020] Reference Figure 2 and Figure 3The heat sink 230 includes at least two rows of mounting rods 231, and the embodiment of the present application preferably includes two rows of mounting rods 231. The multiple mounting rods 231 in one row of mounting rods 231 are spaced apart along the length direction of the bottom plate 210, and the adjacent mounting rods 231 in the two rows of mounting rods 231 are staggered with each other. A plurality of spherical structures 232 are connected in series on one mounting rod 231, and the spherical structures 232 have the same outer diameter. The adjacent spherical structures 232 in the same mounting rod 231 are tangent to each other, the spherical structures 232 in the adjacent mounting rods 231 in one row of mounting rods 231 are tangent to each other, and the sphere centers of the adjacent spherical structures 232 in the adjacent mounting rods 231 are located at the same height. In order to make the sphere center height positions of the adjacent spherical structures 232 in the two rows of mounting rods 231 different, the spherical structures 232 in the adjacent mounting rods 231 in the two adjacent rows of mounting rods 231 have different installation starting positions. The lower end of the mounting rod 231 of one row of mounting rods 231 is connected in series with a cushion block 233, and the cushion block 233 contacts the first spherical structure 232 at the lower end of the mounting rod 231. The side wall of the box 100 is provided with a heat dissipation slot 110, and the heat dissipation slot 110 is close to the heat dissipation frame 230. If wind or dust enters the box 100 through the heat dissipation slot 110 of the box 100, when the spherical structures 232 on the two rows of mounting rods 231 are tangent, the spherical structures 232 are staggered with each other, so that the electric meter is installed on the heat dissipation frame 230, and the heat dissipation frame 230 can not only achieve a heat dissipation effect, but also a barrier effect.

[0021] Reference Figure 2 and Figure 3 , the lower end of one row of mounting rods 231 is connected with a linkage rod 235, the linkage rod 235 is in sliding contact with the bottom plate 210, and the linkage rod 235 can slide close to or away from the mounting rods 231 of other rows. In the embodiment of the present application, a row of mounting rods 231 close to the mounting seat 300 is slidably mounted on the bottom plate 210, and a groove 221 is provided on the lower surface of the top plate 220. After the upper end of the mounting rod 231 is inserted into the groove 221, the lower end of the mounting rod 231 is fixedly connected with the linkage rod 235. When the linkage rod 235 slides, the upper end surface of the mounting rod 231 slides with the bottom wall of the groove 221. A receiving groove 212 is provided on the upper surface of the bottom plate 210, and the linkage rod 235 is located in the receiving groove 212. A guide rod 211 is penetrated through the bottom plate 210, and the guide rod 211 passes through the linkage rod 235. The length direction of the guide rod 211 is the same as the sliding direction of the linkage rod 235. The guide rod 211 guides the linkage rod 235 so that the linkage rod 235 can be stably slidably installed in the receiving groove 212 .

[0022] Reference Figure 3A pressing block 234 is installed on the upper end of the mounting rod 231. The pressing block 234 is threadedly connected to the mounting rod 231. The pressing block 234 contacts the ball structure 232 at the upper end of the mounting rod 231, so that the ball structure 232 is limited. If the pressing block 234 is rotated away from the ball structure 232, the ball can slide up and down on the mounting rod 231. Reference Figure 4 When the linkage rod 235 moves the spherical structures 232 of one row of mounting rods 231 away from the spherical structures 232 of another row of mounting rods 231 , the pressing block 234 is rotated away from the spherical structures 232 , so that the spherical structures 232 can slide up and down.

[0023] Reference Figure 5 and Figure 6 The mounting seat 300 includes a mounting ring 310 and a mounting plate 320, and the mounting plate 320 is fixedly connected to the outer wall of the mounting ring 310. The mounting ring 310 is provided with a through hole 311 for the mounting rod 231 to pass through, and a clearance groove 312 for contacting the outer wall of the spherical structure 232. When the mounting seat 300 is installed on the heat dissipation frame 230, the mounting rod 231 passes through the mounting ring 310, and a mounting ring 310 is installed between two spherical structures 232. The two spherical structures 232 remain in a tangent state, and the spherical structure 232 contacts the inner wall of the clearance groove 312. The spherical structure 232 has a limiting and fixing effect on the mounting ring 310, so that the mounting ring 310 is stably installed between the two spheres. After installing the mounting seat 300, the position of the mounting seat 300 can also be adjusted according to the situation to improve the flexibility of the position adjustment of the mounting seat 300.

[0024] Reference Figure 6 The mounting ring 310 may be provided with a notch 313, through which the mounting rod 231 may directly enter the mounting ring 310. When adjusting the position of the mounting seat 300, the linkage rod 235 and the pressing block 234 may be appropriately moved to allow the ball structure 232 to move up and down. When the mounting ring 310 is installed, the ball structure 232 does not need to leave the mounting rod 231, which facilitates the connection of the mounting ring 310.

[0025] There are at least two mounting rings 310 on a mounting seat 300. The embodiment of the present application has two mounting rings 310. When the mounting rings 310 are distributed up and down on the mounting plate 320, the two mounting rings 310 are simultaneously installed on different spherical structures 232 of a mounting rod 231.

The hollow structure is preferably an array of threaded holes 321, and the threaded holes 321 are threadedly connected with bolts 322. The array of threaded holes 321 is convenient for the installation of electrical components of different models and also helps to dissipate heat. Electronic components are generally installed in the box 100 by bolts 322. For example, before the installation of the electric energy meter, the electric energy meter connector 400 is first threadedly installed. The electric energy meter connector 400 is provided with a waist-shaped hole for the bolt 322 to pass through. The bolt 322 fixes the electric energy meter connector 400 on the mounting plate 320. The mounting seat 300 and the heat dissipation frame 230 are convenient for the installation of electronic components, and also convenient for changing the installation position of electronic components according to the circuit plan, and can also achieve a good heat dissipation effect.

When the mounting seat 300 is mounted on the heat sink 230 , the spherical structure 232 contacts the inner wall of the groove 323 of the mounting plate 320 , thereby increasing the stability of the mounting plate 320 .

[0028] Reference Figure 7 , a plurality of first wiring ports 213 are arranged on the bottom plate 210, and a second wiring port 120 is arranged on the inner bottom wall of the box body 100. The support rod 240 is a hollow structure with openings at both ends. The upper end of the support rod 240 is connected to the first wiring port 213, and the lower end of the support rod 240 is connected to the second wiring port 120. The support rod 240 guides and limits the electric wires. A blocking component is arranged at the second wiring port 120 on the outer wall of the box body 100. The blocking component includes filling particles and a mounting cylinder 500 for containing the filling particles. One end of the mounting cylinder 500 is fixedly mounted on the outer wall of the box body 100. The mounting cylinder 500 is a variable diameter structure. The outer diameter of the end of the mounting cylinder 500 close to the box body 100 is larger, and the outer diameter of the end of the mounting cylinder 500 away from the box body 100 is smaller. The opening with a smaller outer diameter only allows the electric wire to pass through, and the filling particles can only be filled in the mounting cylinder 500. The filling particles are not shown in the embodiment of the present application. The filling particles can be granular activated carbon desiccant. The activated carbon desiccant is made of high-quality sawdust, coconut shells, etc., and is processed by high-temperature activation and special pore size adjustment process. It has a large specific surface area and rich meso and microporous structure. It can not only effectively remove moisture, but also absorb odors and pollutants. It is suitable for moisture-proofing and purification of electrical boxes.

[0029] Reference Figure 8 and Fig. 9In order to facilitate the filling of filling particles, the support rod 240 includes a first support half ring 241 and a second support half ring 242.
