[0015] Preferably, the mounting plate and the side wall of the extension end are provided with a plug hole for inserting the locking screw.

[0016] By adopting the above technical solution, and with the adjustment setting of the mounting plate, the insertion hole is used for the locking screw to be inserted and positioned, thus fixing the mounting plate and the extension end.

[0017] Preferably, a second magnet is fixed to the side wall of the extension end and above the first magnet; when the abutting plate abuts against the adjusting block, the second magnet is magnetically attracted and fixed to the magnetic block.

[0018] By adopting the above technical solution, and with the adjustment setting of the mounting plate, the second magnet is magnetically fixed to the magnetic block, ensuring the positioning of the mounting plate and the extension end.

[0019] Preferably, the threaded end of the locking screw is reduced in diameter and threadedly connected to the side wall of the rear housing.

[0020] By adopting the above technical solution, the threaded end of the locking screw is reduced in diameter, making it easier for the locking screw to pass through the locking plate and the mating plate. At the same time, the distance of the threaded end is reduced, making the fixing of the locking screw faster.

[0021] Preferably, the end of the connecting plate near the slide bar has a deformable sleeve, and the sleeve has an opening groove.

[0022] By adopting the above technical solution, the sleeve with an open groove makes it easier to fit the connecting plate onto the slide rod.

[0023] In summary, this application includes at least one of the following beneficial technical effects: The mounting plate connected to the rear housing is housed in the fixing base and fixed by the locking screw, which improves the convenience of installing and removing the electricity meter, making the installation and use of the electricity meter more convenient and the maintenance more convenient. The first magnet and the magnetic block are positioned in the fixing groove with the magnetic fixing auxiliary extension end. The locking plate and the mating plate are set to provide fixing points for the locking screw. When the locking screw is inserted into the locking plate and the mating plate, the mounting plate and the extension end can be positioned in the fixing groove. The dual fixing method of magnetic attraction and locking screw improves stability. The hanging plate with the hanging hole can hang the electricity meter at the desired position. The corresponding abutment of the limit block and the adjusting block with the abutment plate can adjust the hanging height of the main body. The matching setting of the second magnet and the insertion hole can play a cooperating role when the abutment plate abuts against the adjusting block, so as to fix the main body in this state.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a single-phase electronic prepaid energy meter, referring to... Figure 1 , 2 The system includes a main body 2 mounted on a base plate 1. The main body 2 includes a panel 21 and a rear housing 22. The rear housing 22 is provided with a mounting structure 3. The mounting structure 3 includes a mounting plate 31 movably connected to the rear housing 22 and a fixing seat 32 fixed to the base plate 1. The mounting plate 31 is bent and extended below to form an extension end 311. The fixing seat 32 is provided with a fixing groove 321 that extends through the bottom to accommodate the extension end 311.

[0028] Reference Figure 1 , 2 The mounting structure 3 also includes a slide rod 33 and a connecting plate 34. A support plate 221 is fixed to the upper part of the rear housing 22. The slide rod 33 is fixed between the opposing support plates 221. The connecting plate 34 is fixed above the mounting plate 31. A deformable sleeve 341 is formed at the end of the connecting plate 34 near the slide rod 33. The sleeve 341 has an opening groove and is fitted onto the slide rod 33, so that the connecting plate 34 can slide along the slide rod 33. The extension end 311 can move horizontally to the outside of the fixing groove 321.

[0029] Reference Figure 1 , 3 The rear housing 22 has a receiving groove 222, in which a hanging plate 4 is installed. The hanging plate 4 has a hanging hole 41. A positioning rod that can pass through the hanging hole 41 is fixed on the bottom plate 1 to suspend the main body 2 at the desired position. A limiting block 5 is fixed in the receiving groove 222. An abutment plate 42 extends from the hanging plate 4 and abuts against the bottom of the limiting block 5. The hanging plate 4 has through grooves 42 on both sides of the abutment plate 42 that extend to the bottom, so that the abutment plate 42 can be deformed, making it easier to complete the operation of abutting and disengaging with the limiting block 5. The hanging plate 4 with the hanging hole 41 can suspend the energy meter at the desired position. The abutment plate 42 and the limiting block 5 are used to position the hanging plate 4 and the energy meter.

[0030] Reference Figure 1 , 3 The two sides of the hanging plate 4 extend to form a sliding plate 411. The two sides of the receiving groove 222 are connected to the sliding groove 223 for the sliding plate 411 to slide. An adjusting block 6 is fixed directly above the limiting block 5. The abutting plate 42 can abut against the lower part of the adjusting block 6. The sliding plate 411 slides along the sliding groove 223, and the abutting plate 42 can abut against the adjusting block 6 to adjust the suspension height of the main body 2.

[0031] Reference Figure 1 , 4 The extension end 311, which is housed in the fixing groove 321, is fixed by the locking structure 7. The locking structure 7 includes a first magnet 71 fixed on the side wall of the extension end 311 and a magnetic block 72 fixed below the fixing base 32. When the extension end 311 is fixed in the fixing groove 321, the first magnet 71 and the magnetic block 72 are magnetically attracted and fixed, thus assisting the extension end 311 in being positioned in the fixing groove 321.

[0032] Reference Figure 2 A second magnet 8 is fixed on the side wall of the extension end 311 and directly above the first magnet 71. When the abutting plate 42 abuts against the adjusting block 6, the rear housing 22 descends relative to the hanging plate 4, and the extension end 311 descends in the fixing groove 321. The second magnet 8 is magnetically fixed to the magnetic block 72. With the adjustment of the hanging plate 4, the positioning of the mounting plate 31 and the extension end 311 is ensured.

[0033] Reference Figure 1 , 4 The locking structure 7 also includes a locking screw 73 that passes through and is positioned at the corresponding locations of the mounting plate 31 and the fixing seat 32. A locking plate 312 is fixed to the bottom of the extension end 311, and a mating plate 322 is fixed to the bottom of the fixing seat 32. The locking screw 73 passes through the locking plate 312 and the mating plate 322 and is threadedly connected to the side wall of the rear housing 22. The locking plate 312 and the mating plate 322 are configured to provide fixing points for the locking screw 73. When the locking screw 73 is inserted into the locking plate 312 and the mating plate 322, the mounting plate 31 and the extension end 311 can be positioned in the fixing groove 321. The first magnet 71 and the magnetic block 72 are magnetically fixed to each other, which facilitates the through-positioning of the locking screw 73 and provides a double locking function with the locking screw 73.

[0034] Reference Figure 2 , 4 The threaded end of the locking screw 73 is reduced in diameter and threadedly connected to the side wall of the rear housing 22. The reduced diameter of the threaded end of the locking screw 73 makes it easier for the locking screw 73 to pass through the locking plate 312 and the mating plate 322, and at the same time reduces the distance of the threaded end, making it easier to fix the locking screw 73.

[0035] Reference Figure 2The mounting plate 31 and the extension end 311 have insertion holes 9 on their side walls, above the locking plate 312, for the locking screw 73 to be inserted. When the abutting plate 42 abuts against the adjusting block 6, the rear housing 22 descends relative to the hanging plate 4, and the insertion holes 9 allow the locking screw 73 to be inserted and positioned. This, together with the adjustment of the hanging plate 4, achieves the purpose of fixing the mounting plate 31 and the extension end 311.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
