[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The utility model provides Figure 1-4An electric power meter shown in the figure comprises a mounting seat 1 and a meter body 2, a mounting opening adapted to the meter body 2 is provided on the front side of the mounting seat 1, mounting blocks 3 are connected to both sides of the meter body 2, a through opening is provided on the mounting block 3, a clamping structure 4 is connected to the through opening, the clamping structure 4 comprises a rod 5 connected to the through opening, an extension rod 6 is connected to one end of the rod 5, a limiting block 7 is connected to one end of the extension rod 6, a sleeve 8 is connected to one side of the through opening, a spring 9 is connected between the sleeve 8 and the rod 5, clamping openings are provided on both sides of the sleeve 8, a clamping ball 10 is connected to the clamping opening, mounting grooves corresponding to the clamping structure 4 are provided on both sides of the mounting seat 1, so that the meter body 2 and the mounting seat 1 are fixed to each other.

[0018] A first cavity is provided inside the meter body 2, and an anti-interference layer 11 is provided in the first cavity. The specific material of the anti-interference layer 11 is synthetic resin, which prevents the reading of the meter body 2 from being inaccurate due to electromagnetic influence of peripheral electrical equipment.

[0019] A second cavity is provided inside the meter body 2 , and a heat insulating layer 12 is provided inside the second cavity to prevent the meter body 2 from being damaged due to excessive height or low depth.

[0020] The top of the installation opening is connected to a transparent plastic plate 13 by a hinge to protect the surface of the instrument body 2.

[0021] The surfaces of the mounting seat 1 and the clamping structure 4 are coated with anti-corrosion paint, which prolongs the service life of the mounting seat 1 and the clamping structure 4.

[0022] The working principle of the utility model is as follows: the rod 5 is pressed down, the spring 9 is compressed and contracted, and the rod 5 drives the limit block 7 to move through the extension rod 6. Due to the shape of the limit block 7 and the spatial distribution inside the sleeve 8, the clamping ball 10 moves between the limit block 7 and the extension rod 6, and the instrument body 2 is placed in the mounting opening of the mounting seat 1. After the clamping structure 4 is placed in the mounting groove, the rod 5 is no longer pressed down.
