Detailed ways

The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

Please refer to Figures 1 and 2. The utility model provides an electric meter box, including a box body 1, in which an electric meter 2, a current transformer 3 and a fuse module 4 are arranged. A slide rail 5 is fixed in the box body 1, and both sides of the top of the slide rail 5 are provided with convex edges protruding outward. The electric meter 2, the current transformer 3 and the fuse module 4 are all provided with a first slide groove 6 and a locking bolt 7. The shape of the first slide groove 6 is adapted to the slide rail 5 and is sleeved on the slide rail 5. The electric meter 2, the current transformer 3 and the fuse module 4 are all provided with threaded holes. The locking bolt 7 is threadedly connected with the threaded hole and abuts against the box body 1 or the slide rail 5 to fix the electric meter 2, the current transformer 3 and the fuse module 4 on the box body 1.

The electric meter 2, the current transformer 3 and the insurance module 4 are initially positioned in the electric meter 2 box by the cooperation of the slide rail 5 and the first slide groove 6, and then the electric meter 2, the current transformer 3 and the insurance module 4 are completely locked with the locking bolt 7. During maintenance, only one locking bolt 7 needs to be removed to remove the components, which makes the operation more convenient. When replacing components of different models, there is no need to redesign the holes on the box 1, thereby improving the applicability of the box 1.

Furthermore, the slide rail 5 is provided with a positioning hole 52. When connecting, the locking bolt 7 is inserted into the positioning hole 52 to enhance the connection strength between the locking bolt 7 and the box body 1.

Furthermore, a connecting plate 71 is fixed to the electric meter 2 , the current transformer 3 and the insurance module 4 , and threaded holes are provided on the connecting plate 71 .

By setting the connecting plate 71, there is no need to directly open threaded holes on the components, the original structure of the components does not need to be destroyed, and the position of the threaded holes does not need to be restricted by the component structure, so that the installation position of the components in the box body 1 is more flexible and the space of the box body 1 can be better allocated.

Furthermore, the slide rails 5 are arranged at three locations, and the three slide rails 5 are arranged staggered. When the electric meter 2, the current transformer 3 and the insurance module 4 are installed, mutual interference can be avoided, and installation is convenient.

Furthermore, a bracket 8 is disposed in the box body 1 , and the slide rail 5 is disposed on the bracket 8 .

Furthermore, the bracket 8 includes two support plates 81 and a cross plate 82. The support plate 81 is fixed in the box body 1. A second slide groove 86 is provided on the support plate 81. A mounting opening 83 is provided at the bottom of the second slide groove 86. Slide rods 84 are provided on both sides of the cross plate 82. A hook plate 85 is provided at one end of the slide rod 84 facing away from the cross plate 82. A spring is provided between the box body 1 and the cross plate 82.

By setting the bracket 8, the heat dissipation performance of the internal components can be enhanced. By setting the spring and the slidable horizontal plate 82, the vibration of the building can be filtered to prevent the vibration from affecting the operation of the internal components. The design of the hook plate 85 can hook the support plate 81 from both sides to lock the position of the horizontal plate 82. The design of the installation opening 83 allows the hook plate 85 to pass through the installation opening 83, so that the slide bar 84 and the second slide groove 86 can cooperate smoothly, and it is convenient to disassemble and assemble the horizontal plate 82.

The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
