DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 4 , an assembly structure of a single-phase electronic electric energy meter, comprising a box seat 1, a front cover 11, a meter body 12 and a terminal block 13, the terminal block 13 is fixedly installed below the meter body 12, the box seat and the front cover 11 are fixedly connected through a mounting assembly 2, the meter body 12 is fixedly installed on the box seat 1, the front cover 11 is covered on the meter body 12 and the terminal block 13, a threading port is opened at the bottom end of the front cover 11, a fixing assembly 4 is installed on the box seat, and the fixing assembly 4 is used to help the front cover 11 to be installed;

[0024] The mounting assembly 2 includes a bolt 21 , a threaded groove 22 and a threaded opening 23 . The threaded groove 22 is formed at the four corners of the box seat 1 , and the threaded opening 23 is formed at the four corners of the front cover 11 and aligned with the threaded groove 22 . The bolt 21 passes through the threaded opening 23 and is threadedly connected in the threaded groove 22 .

[0025] A maintenance opening is provided on the front cover 11, and the maintenance opening is aligned with the wiring seat 13. A cover plate 3 is hinged on the maintenance opening, and a fixing lock is installed on the cover plate 3. The fixing lock locks the cover plate 3 and the front cover 11, thereby protecting the interior;

[0026] The fixing assembly 4 includes a fixing plate 41, an elastic compression rod 42, a limiting head 5 and a limiting plate 43. The fixing plate 41 is fixedly mounted on the upper and lower ends of the box seat 1, and the elastic compression rod 42 is rotatably mounted on the fixing plate 41. The limiting head 5 is fixedly mounted on the end of the elastic compression rod 42, and the limiting plate 43 is fixedly mounted on the upper and lower ends of the front cover 11. A through-hole of the same shape as the limiting head 5 is opened on the limiting plate 43. After the limiting head 5 passes through the limiting plate 43, it rotates and clamps the limiting plate 43. When the bolts 21 are installed at the four corners, it is inconvenient for one person to install. By first installing the front cover 11 and the fixing assembly 4, it is more convenient to install the installation assembly 2. During installation, the elastic compression rod 42 is first rotated to align the limiting head 5 with the through-hole, and then the elastic compression rod 42 is rotated to misalign the limiting head 5 with the through-hole, and the elastic compression rod 42 retracts to press the limiting plate 43;

[0027] The limiting head 5 includes a middle block 51 and two wings 52. The middle block 51 is fixedly mounted on the elastic compression rod 42. The two wings 52 are symmetrically mounted on both sides of the middle block 51. After the elastic compression rod 42 rotates, the two wings 52 are no longer aligned with the through opening, so that the limiting head 5 presses the limiting plate 43.

[0028] The front cover 11 is provided with an observation port, in which a transparent plate 6 is rotatably installed, and the transparent plate 6 can be used to observe the display data on the meter body 12.

[0029] Card slots are provided on both sides of the lower end of the observation port, and elastic card blocks 7 are symmetrically installed on both sides of the lower end of the transparent plate 6. The elastic card blocks 7 are clamped in the card slots. A handle is installed on the transparent plate 6. The elastic card blocks 7 fix the transparent plate 6. When the transparent plate 6 needs to be opened, the handle is pulled and the elastic card blocks 7 are squeezed, so that the transparent plate 6 can be opened.

[0030] In the utility model, the front cover 11 and the box seat 1 buckle the meter body 12 and the terminal block 13 through the installation component 2, the four corners of the front cover 11 and the box seat 1 are fixed by bolts 21, the connecting wire is connected to the terminal block 13 through the threading port, and the front cover 11 covers the meter body 12 and the terminal block 13 as a whole, so that the terminal block 13 is not easily damaged.

[0031] In general, in response to the technical problem that the terminal socket of the electric energy meter is exposed to the outside and is prone to damage, a technical solution is adopted: the front cover covers the meter body and the terminal socket as a whole; because the implementation process of the technical solution is: the front cover 11 and the box seat 1 buckle the meter body 12 and the terminal socket 13 through the installation component 2, the four corners of the front cover 11 and the box seat 1 are fixed by bolts 21, the connecting wire is connected to the terminal socket 13 through the threading port, and the front cover 11 covers the meter body 12 and the terminal socket 13 as a whole; so the technical problem can definitely be solved, and the technical effect achieved is: making the terminal socket 13 not easily damaged.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
