In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, a movable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] like Figure 1-3 In the present embodiment, an electric energy meter box that is easy to load and unload includes a meter box body 1 and a mounting base 2. A fixing plate 3 is installed on the rear side of the meter box body 1. The mounting base 2 is installed on the wall by bolts. Two first clamping mechanisms 4 that are symmetrical to each other are provided in the mounting base 2. The first clamping mechanism 4 is composed of a first fixing block 41, a first threaded rod 42, and a first clamping plate 43. A second clamping mechanism 5 is installed on the upper part of the mounting base 2. The second clamping mechanism 5 is composed of a second fixing block 51, a second threaded rod 52, and a second clamping plate 53. A positioning plate 21 is installed on the lower part of the mounting base 2 corresponding to the second clamping mechanism 5. A first positioning groove 31 is opened in the middle of the top end of the fixing plate 3, and a second positioning groove 32 is opened in the middle of the bottom end. The fixing plate 3 can be detachably installed in the mounting base 2 through the first clamping mechanism 4, the second clamping mechanism 5 and the positioning plate 21.

[0020] Through the above technical scheme, when in use, the mounting base 2 is fixed to the wall by bolts, and then the fixing plate 3 is installed on the rear side of the metering box body 1. After assembly, the fixing plate 3 is placed on the positioning plate 21 of the mounting base 2, and then the first threaded rods 42 in the two first clamping mechanisms 4 are driven to rotate and displace in the first fixing block 41, thereby driving the first clamping plate 43 to displace, thereby making the two first clamping plates 43 in the two first clamping mechanisms 4 clamp the two side surfaces of the fixing plate 3, and then the second threaded rod 52 in the second clamping mechanism 5 is rotated, so that the second threaded rod 52 is rotated and displaced in the second fixing block 51, driving the second clamping plate 53 to displace, so that the second clamping plate 53 is pressed down on the top of the fixing plate 3. The first clamping mechanism 4, the second clamping mechanism 5 and the positioning plate 21 are used to stably clamp the fixed plate 3 in the mounting base 2 to complete the installation of the metering box body 1. Due to the adjustability of the first clamping mechanism 4 and the second clamping mechanism 5, the fixed plates 3 of different heights and widths can be clamped, and thus the metering box bodies 1 of different sizes can be clamped. During disassembly, the second clamping mechanism 5 is first driven to move the second clamping plate 53 upward to release the pressure on the top of the fixed plate 3, and then the two first clamping mechanisms 4 are driven to move the first clamping plates 43 to release the clamping on both sides of the fixed plate 3, and then the metering box body 1 together with the fixed plate 3 is removed from the positioning plate 21 on the mounting base 2, so that the maintenance and replacement of the metering box body 1 is more convenient.

[0021] Preferably: the first fixing blocks 41 in the two first clamping mechanisms 4 are fixedly connected to the mounting base 2 in a left-right symmetrical manner, the first threaded rod 42 is threadedly connected to the first fixing block 41, and the first clamping plate 43 is connected to the end of the first threaded rod 42 located on the inner side of the first fixing block 41, the end of the first threaded rod 42 away from the first clamping plate 43 is fixedly connected with a handle, and a layer of rubber anti-slip pad 6 is fixedly provided on the clamping surface of the first clamping plate 43.

[0022] Through the above technical solution, the setting of the handle of the first threaded rod 42 is convenient for driving the first threaded rod 42 to rotate, thereby driving the first clamping plate 43 to move. The setting of the rubber anti-slip pad 8 prevents rigid collision between the first clamping plate 43 and the fixed plate 3 to extend the service life of the equipment, and at the same time increases friction, so that the first clamping plate 43 can clamp the side of the fixed plate 3 more stably.

[0023] Preferably: the second fixing block 51 in the second clamping mechanism 5 is fixedly connected to the upper part of the mounting base 2, the second threaded rod 52 is threadedly connected to the second fixing block 51, and the second clamping plate 53 is connected to the end of the second threaded rod 52 located on the inner side of the second fixing block 51, the end of the second threaded rod 52 away from the second clamping plate 53 is fixedly connected with a handle, the middle part of the clamping surface of the second clamping plate 53 is provided with a first positioning block 54 which is inserted into the first positioning groove 31 in the fixing plate 3, and a layer of rubber anti-slip pad 6 is fixedly provided in the clamping surface of the second clamping plate 53.

[0024] Through the above technical solution, the handle of the second threaded rod 52 is convenient for driving the second threaded rod 52 to rotate, thereby driving the second clamping plate 53 to move. Through the first positioning block 54 in the second clamping plate 53, the first positioning groove 31 on the top of the plug-in fixing plate 3 is inserted, so that the second clamping plate 53 clamps and positions the fixing plate 3 more stably. The setting of the rubber anti-slip pad 7 avoids the rigid collision between the clamping surface of the second clamping plate 53 and the top of the fixing plate 3, which extends the service life of the equipment, and at the same time increases the friction force to make the clamping more stable.

[0025] Preferably, a second positioning block 22 inserted into the second positioning groove 32 in the fixing plate 3 is provided in the middle of the positioning plate 21 , and a layer of rubber anti-skid pad 6 is fixed on the upper surface of the positioning plate 21 .

[0026] Through the above technical scheme, the second positioning block 22 in the positioning plate 21 cooperates with the second positioning groove 32 in the fixing plate 3 to limit the position of the fixing plate 3 in the mounting base 2 during installation, which is convenient for the subsequent operation of the first clamping mechanism 4 and the second clamping mechanism 5, and at the same time can more stably place the fixing plate 3 in the positioning plate 21. The setting of the rubber anti-slip pad 7 can prevent the rigid collision between the bottom of the fixing plate 3 and the positioning plate 21 when the fixing plate 3 is subjected to the pressure of the second clamping plate 53, and at the same time increase the friction force to improve the stability of the clamping.

[0027] Finally, it should be noted that the above implementation cases are only used to illustrate the present invention, rather than to limit the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above-mentioned embodiments, ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention; technologies not described in detail in the present invention are implemented with existing technologies.
