the

1 is provided with at least one first ammeter mounting hole 1-1, at least two fixing holes 1-2 and a strip-shaped sliding groove 1-3 arranged along the length direction of the

1; the first electric meter mounting hole 1-1 is formed in the upper end of the

1 and used for mounting an electric meter on an electric meter bracket; the

1 is arranged on the bottom surface of the

3 through screws and the fixing holes 1-2, and the fixing holes 1-2 are waist holes in the example, so that the position of the

1 relative to the

3 can be adjusted according to needs;

the

2 comprises a first bracket 2-1 and a second bracket 2-2 which are hinged with each other, and a hinged shaft of the

2 is slidably arranged in the chute 1-3 so as to realize the relative movement of the

2 relative to the

1 and adapt to electric meters of different models and specifications; the free ends of the first support 2-1 and the second support 2-2 extend towards the bottom surface of the

3 to form a support part 2-4, the bottom of the support part is supported on a

4 on the bottom surface of the

3, and the support part is utilized to provide certain supporting force for the free ends of the first support 2-1 and the second support 2-2, so that the supports are more stable integrally and avoid shaking. The first bracket 2-1 and the second bracket 2-2 are respectively provided with a second ammeter mounting hole 2-3 at the free end, in this case, the second ammeter mounting holes penetrate through the unfolding bracket 2 (the free ends of the first bracket 2-1 and the second bracket 2-2) and the supporting part 2-4; when the electric meter is installed, the upper end of the electric meter is fixed on the

1 through screws and the first electric meter installation holes 1-1, and the lower end of the electric meter is fixed on the

2 through screws and the second electric meter installation holes 2-3.

In this example, the bottom surface of the

3 is symmetrically provided with a plurality of groups of

4, the distance between each group of

4 and the

1 is different, the bosses are used for mounting electric meters of different specifications and models, copper inserts for threaded connection are embedded in the

4, and when the electric meter box is used, fastening

6 can sequentially penetrate through the

5 and the second electric meter mounting holes 2-3 and then are in threaded connection with the copper inserts to fix the electric meter.

In order to ensure the positioning of the

2 at different positions on the

1, in this example, the bottom of the

3 and the position corresponding to the sliding chute 1-3 are provided with a plurality of

7 along the length direction of the sliding chute 1-3, the positioning platforms are provided with threaded holes, the end parts of the hinged shafts of the first bracket 2-1 and the second bracket 2-2 are provided with external threads (the whole structure of the hinged shaft is similar to a sunk screw, the part hinged with the first bracket and the second bracket is a smooth surface and is not provided with threads), when the

2 slides to any

7, one end of the hinged shaft provided with the external threads is screwed into the threaded hole of the

7, so as to realize the positioning of the

2.

As shown in fig. 3-5, the utility model relates to a connection structure of ammeter and ammeter support, including

5 and the aforementioned ammeter support, wherein on the upper end of

5 was fixed in

1 through screw and first ammeter mounting hole 1-1, the lower extreme was fixed in respectively on first support 2-1 and second support 2-2 through two

6 and two second ammeter mounting holes 2-3, specifically was: the

6 sequentially penetrates through the

5 and the second ammeter mounting holes 2-3 and then is in threaded connection with the copper insert, so that the

5, the ammeter support and the

3 are connected into a whole, and the stability is better.

When the sizes of all the groups of

4 do not accord with the size of the electric meter to be installed (specifically: when the copper insert in the boss is not coaxial with the second electric meter installation hole), the lower end of the

5 is installed on the second electric meter installation hole 2-3 through the

6, the

6 is only connected with the

5 and the

2, and the support parts 2-4 are abutted against the upper surface of the

4, so that the integral stability is ensured.

This embodiment is substantially the same as

1 except that the bottom of the

3 has no

4, and the bottoms of the support parts 2-4 are directly supported on the bottom surface of the

3; the

5 forms a connection only with the electricity meter holder.
