[0029] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figure 1-Figure 5As shown, the utility model proposes a combined three-phase multi-meter metal meter box, including a base 1, a combined box body is installed on the top of the base 1, and the combined box body is composed of several U-shaped assembly boxes 2. The horizontal direction is composed of two symmetrically arranged U-shaped assembly boxes 2 spliced ​​together, and the vertical direction is composed of multiple stacked and spliced ​​U-shaped assembly boxes 2. The tops of the two U-shaped assembly boxes 2 on the top are jointly snap-fitted with a box cover 3, and a box door 4 is rotatably installed on the front metal plate of each U-shaped assembly box 2. When the box door 4 is in a closed state, the above-mentioned base 1, U-shaped assembly box 2 and box cover 3 can form a closed box body to ensure that electrical components such as meters and control switches can be protected by the metal box; the above-mentioned U-shaped assembly box 2 is an open structure at the top, bottom and one side. The multi-opening structure is convenient for assembly, and the weight of the independent assembly box is also reduced, which is convenient for moving; a heat dissipation port 8 is cut on the rear metal plate of the above-mentioned U-shaped assembly box 2, and the heat dissipation port 8 is mainly used for heat dissipation of the metering box, and wires can be threaded through the heat dissipation port 8 so that the external cables can be electrically connected to the electrical components inside the metal box; a built-in mounting bracket 5 is fixedly installed on the inner wall of the above-mentioned U-shaped assembly box 2, and the built-in mounting bracket 5 can be adjusted up and down. The height of the built-in mounting bracket 5 can be adjusted according to the actual installation situation, which is convenient for adjusting the distance between adjacent electrical components in the vertical direction. With the free combination of the U-shaped assembly box 2, the limited internal space of the metering box can avoid hindering the installation of the meter, thereby effectively improving the flexibility of the meter installation.

[0032] Furthermore, slots 6 are bored on the top of the base 1 and the U-shaped assembly box 2, and positioning plates 9 and limiting plates 10 are fixedly installed on the bottom of the U-shaped assembly box 2 and the box cover 3. The above-mentioned positioning plates 9 and limiting plates 10 are inserted into the slots 6 set below them and engaged with them, and second bolts 7 are threadedly installed on the base 1 and the U-shaped assembly box 2. When the positioning plates 9 are inserted into the corresponding slots 6, the second bolts 7 are rotated toward the inside of the slots 6. When the second bolts 7 are threadedly connected with the positioning plates 9, the positioning plates 9 can be locked and fixed. Combined with the limitation of one side of the U-shaped assembly box 2 by the limiting plates 10, a firm connection can be formed between the two U-shaped assembly boxes 2 adjacent to each other in the vertical direction, between the base 1 and the U-shaped assembly box 2 set above it, and between the box cover 3 and the U-shaped assembly box 2 set below it, thereby effectively improving the firmness of the combined box body after assembly.

[0033] Secondly, a rectangular opening is cut out on the front metal plate of the U-shaped assembly box 2, and the box door 4 is rotatably installed at the above-mentioned rectangular opening. A rotary lock 41 is fixedly installed on the above-mentioned box door 4. When the box door 4 is closed, the lock of the rotary lock 41 is rotated by the key to lock the box door 4 on the U-shaped assembly box 2. After opening the box door 4, the electrical components inside the metering box can be installed and maintained; a glass window 42 is fixedly installed on the above-mentioned box door 4, through which the data displayed on the meter can be observed, which is convenient for observation and recording.

[0034] Furthermore, the above-mentioned built-in mounting frame 5 is composed of an L-shaped limiting plate 51, a lifting plate 52, a support plate 54 and a reinforcement plate 55. There are at least two L-shaped limiting plates 51, and a lifting plate 52 is movably installed between the two L-shaped limiting plates 51. The two ends of the lifting plate 52 are inserted into the gap between the L-shaped limiting plate 51 and the inner wall of the U-shaped assembly box 2, which can limit the two ends of the lifting plate 52 to ensure its stable lifting and lowering adjustment; there are at least two above-mentioned support plates 54, which are fixed on one side of the lifting plate 52, and a plurality of reinforcement plates 55 are fixedly installed between the two support plates 54. The reinforcement plates 55 can allow the two support plates 5 4 is connected as one body to make its structure more solid. The above-mentioned support plate 54 and reinforcement plate 55 form a stable support surface for installing electrical components such as meters and control switches, ensuring that the electrical components can be stably installed in the meter box; the above-mentioned L-shaped limit plate 51 is threadedly installed with a first bolt 53, and a positioning groove 524 is cut on the lifting plate 52. The end of the above-mentioned first bolt 53 passes through the L-shaped limit plate 51 and is inserted into the positioning groove 524 and movably connected thereto, thereby locking and fixing the lifting plate 52 to prevent it from sliding down. After removing the first bolt 53, the height of the lifting plate 52 can be adjusted, which facilitates adjustment of the spacing between electrical components.

[0035] Secondly, grooves 521 are carved at both ends of the lifting plate 52 away from each other, and a number of rollers 522 are rotatably installed in the grooves 521. One end of the roller 522 extends to the outside of the groove 521 and contacts the inner wall of the L-shaped limit plate 51. When the lifting plate 52 is raised and lowered, the rollers 522 can improve its smoothness and facilitate the lifting and lowering of the lifting plate 52; a rubber plate 523 is fixedly installed on the side of the lifting plate 52 close to the U-shaped assembly box 2, and the end of the first bolt 53 is not inserted When inside the positioning groove 524, a gap remains between the rubber plate 523 and the U-shaped assembly box 2. Therefore, when adjusting the height of the lifting plate 52, no resistance is caused to the lifting plate 52. When the end of the first bolt 53 is inserted into the positioning groove 524, the lifting plate 52 is pushed toward the inner wall of the U-shaped assembly box 2. At this time, the rubber plate 523 fits tightly against the inner wall of the U-shaped assembly box 2, thereby increasing the friction between the lifting plate 52 and the inner wall of the U-shaped assembly box 2, further reducing the chance of the lifting plate 52 sliding down.

[0036] In this embodiment, first, during the assembly of the metering box, the U-shaped assembly box 2 is installed on the top of the base 1. After the positioning plug plate 9 and the limit plug plate 10 are inserted into the slot 6 opened at the top of the base 1, the second bolt 7 threadedly installed on the base 1 is rotated to lock the positioning plug plate 9, so that the two U-shaped assembly boxes 2 can be fixed on the base 1. Then, the box cover 3 is installed on the top of the U-shaped assembly box 2. At this time, the positioning plug plate 9 and the limit plug plate 10 on the box cover 3 are inserted into the slot 6 at the top of the U-shaped assembly box 2. The U-shaped assembly box 2 is rotated. The second bolt 7 is threadedly installed and the positioning plug plate 9 is locked and fixed to ensure that the box cover 3 can be firmly installed on the U-shaped assembly box 2. The closed box body is composed of the base 1, two U-shaped assembly boxes 2 and the box cover 3. At this time, the capacity of the metering box is the smallest. If more electrical components such as meters and control switches need to be installed, more U-shaped assembly boxes 2 can be installed on the top of the U-shaped assembly box 2. According to actual needs, after installing the corresponding number, the box cover 3 can be fixed on the top of the top-level U-shaped assembly box 2, which is convenient for expanding the capacity of the metering box.

[0037] During the installation stage of electrical components such as meters and control switches, the electrical components are fixed on the top of the support plate 54 or the reinforcement plate 55. The support surface composed of the support plate 54 and the reinforcement plate 55 can allow the electrical components to be firmly mounted inside the meter box; during the actual installation process, if the installation spacing between two adjacent electrical components in the vertical direction is insufficient, the height of the lifting plate 52 can be adjusted. Since the lifting plate 52 is movably installed in the gap between the L-shaped limit plate 51 and the inner wall of the U-shaped assembly box 2, the lock of the lifting plate 52 can be released by removing the first bolt 53 installed on the L-shaped limit plate 51, so that it is convenient to lift and adjust it; adjust the lifting plate 52 located at the bottom downward and the lifting plate 52 located at the top upward, and then increase the spacing between the two groups of support surfaces composed of the support plate 54 and the reinforcement plate 55 in the vertical direction, so that electrical components with large height can be installed and the spacing between the electrical component installation structures can be avoided. The distance is limited, and large electrical components cannot be installed; after the height adjustment of the lifting plate 52 is completed, the first bolt 53 threadedly installed on the L-shaped limit plate 51 is rotated, and when the end of the first bolt 53 is embedded in the positioning groove 524 excavated on the lifting plate 52, the lifting plate 52 can be locked and fixed, which can prevent the electrical components installed on the top of the support plate 54 and the reinforcement plate 55 from sliding down, thereby improving the stability of the electrical components after installation; the metal meter box in the present application is assembled by multiple U-shaped assembly boxes 2, which is convenient for expanding the overall capacity inside the meter box, and more meters can be installed in the meter box, which is suitable for multi-meter installation operations, and the support structure for installing electrical components such as meters can be raised and lowered, which can cope with the installation of electrical components of different sizes, solves the problem of limited installation space inside the meter box, which is difficult to adapt to the installation of electrical components of different sizes, and effectively improves the flexibility of meter installation.
