[0014] The above-mentioned technical solutions of one or more technical solutions in the indoor voltage transformer provided by this utility model embodiment have at least one of the following technical effects:

[0015] This utility model, through the above-described technical solution, achieves the following installation: during installation, the mounting plate is inserted into the mounting groove, and the elastic element two pushes the insertion rod into the insertion hole to fix the mounting plate, thus fixing the mounting plate in the mounting groove and achieving the installation and fixation of the current transformer. During disassembly, the insertion rod is pulled out of the insertion hole by pushing the push block. At this time, the elastic element one pushes the push rod, causing the push plate to push the current transformer out of the mounting groove, and then the mounting plate is pulled out of the mounting groove to complete the disassembly. This utility model eliminates the need for screws and operating tools when installing the current transformer, making both installation and disassembly simple and convenient.

[0026] like Figure 1-5 The diagram shown is a structural schematic of an indoor voltage transformer according to a preferred embodiment of the present invention.

[0027] In this embodiment, the device includes a mounting base 1 and a current transformer 2. Mounting plates 3 are provided on both sides of the bottom of the current transformer 2. Rollers 4 are provided on the front and rear sides of the mounting plates 3. Insertion holes 5 are provided on the outer sides of the mounting plates 3. A mounting groove 6 is provided on the top of the mounting base 1. A push rod groove 7 is provided on the rear wall of the mounting groove 6. A push rod 8 is movably mounted in the push rod groove 7. An elastic element 9 is provided in the push rod groove 7, with its two ends abutting against the push rod groove 7 and the push rod 8, respectively. A push plate 10 is provided on the front side of the push rod 8, abutting against the rear side of the current transformer 2. Sliding grooves 11 are provided on both sides of the bottom wall of the mounting groove 6. Insertion rods 12 are slidably mounted in the sliding grooves 11. An elastic element 13 is provided in the sliding grooves 11, with its two ends abutting against the sliding grooves 11 and the insertion rods 12, respectively. The mounting plate 3 is inserted into the mounting groove 6, and the insertion rods 12 are inserted into the insertion holes 5. During installation, the mounting plate 3 is inserted into the mounting groove 6, and the elastic element 13 pushes the insertion rod 12 into the insertion hole 5 to fix the mounting plate 3. By fixing the mounting plate 3 in the mounting groove 6, the current transformer 2 can be installed and fixed. During disassembly, the insertion rod 12 is pulled out of the insertion hole 5 by pushing the push block 15. At that time, the elastic element 9 pushes the push rod 8, which pushes the push plate 10 to move the current transformer 2 out of the mounting groove 6. Then, the mounting plate 3 is pulled out of the mounting groove 6 to complete the disassembly. This utility model makes it possible to install the current transformer 1 without the use of screws and operating tools, thus making the installation and disassembly simple and convenient.

[0028] In this embodiment, both the first elastic element 9 and the second elastic element 13 are springs, which provide power to the push rod 8 and the insertion rod 12, respectively.

[0029] In this embodiment, the outer wall of the sliding groove 11 is provided with a through groove 14, and the outer side of the insertion rod 12 is provided with a push block 15. The push block 15 passes through the through groove 14 and extends to the outside of the mounting base 1. By pushing the push block 15, the insertion rod 12 is pulled out from the insertion hole 5.

[0030] In this embodiment, the top front side of the insertion rod 12 is provided with an inclined surface. When the mounting plate 3 is inserted into the mounting groove 6 and abuts against the top of the insertion rod 12, the insertion rod 12 is squeezed down by the mounting plate 3 and slides into the sliding groove 11.

[0031] In this embodiment, roller grooves 16 are provided on both sides of the bottom wall of the mounting groove 6. The roller 4 is rolled in the roller groove 16. The roller groove 16 plays a guiding role and reduces the friction between the mounting plate 3 and the mounting groove 6, so that the mounting plate 3 slides more smoothly in the mounting groove 6.

[0032] In this embodiment, the mounting base 1 is provided with fixing blocks 17 on both sides, and the mounting base 1 is fixed in the designated area by screws through the fixing blocks 17.

[0033] The indoor voltage transformer of this utility model can be installed, connected or set in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effect.

[0034] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.
