DETAILED DESCRIPTION

[0016] Reference Figures 1 to 3 The utility model is further described in detail.

[0017] An electric energy meter that is easy to disassemble comprises an electric energy meter body 1, a bottom plate 2, a shell 3, a clamping piece 4, a fixing piece 10 and a first annular plate 9. A limiting groove 8 is provided on the bottom plate 2. The first annular plate 9 is fixed in the limiting groove 8. The electric energy meter body 1 is fixedly connected to the fixing piece 10 and the electric energy meter body 1 is placed on the first annular plate 9. The electric energy meter body 1 is detachably connected to the first annular plate 9 through the fixing piece 10. The shell 3 is detachably connected to the bottom plate 2 through the clamping piece 4.

[0018] The clamping member 4 includes a connecting block 41, a spring 42, a limiting block 43 and a U-shaped plate 44. The connecting block 41 is fixed to the housing 3. A first positioning groove 5 is formed on the connecting block 41. The spring 42 extends into the first positioning groove 5 and one end of the spring 42 is fixed to the inner wall of the first positioning groove 5. The limiting block 43 extends into the first positioning groove 5 and is fixedly connected to the other end of the spring 42. The U-shaped plate 44 is fixed to the bottom plate 2 and corresponds to the connecting block 41. A second positioning groove 6 corresponding to the first positioning groove 5 is formed on the U-shaped plate 44. The U-shaped plate 44 is fixed to the bottom plate 2 to form a storage space 7. The connecting block 41 extends into the storage space 7, and one end of the limiting block 43 extends into the second positioning groove 6.

[0019] By squeezing the limit block 43, the limit block 43 moves into the first positioning groove 5, and the limit block 43 squeezes the spring 42, so that the spring 42 shrinks and deforms, until the limit block 43 is moved out of the second positioning groove 6, and the connecting block 41 is moved out of the storage space 7, so that the shell 3 is separated from the bottom plate 2, and the electric energy meter body 1 is exposed, so that the structure is simple to install and disassemble, thereby improving the work efficiency of installation and disassembly.

[0020] The fixing member 10 includes a connecting plate 101 and a hook 102. The connecting plate 101 is fixed to both sides of the electric energy meter body 1. The hook 102 is fixedly connected to the connecting plate 101. The electric energy meter body 1 extends into the limiting groove 8 and the hook 102 is clamped with the first annular plate 9.

[0021] The electric energy meter body 1 is extended into the limiting groove 8 and contacts the first annular plate 9, and at the same time the connecting plate 101 passes through the first annular plate 9 and the hook 102 on the connecting plate 101 is engaged with the first annular plate 9, thereby fixing the electric energy meter body 1 on the first annular plate 9, and then the electric energy meter body 1 is easy to disassemble by engaging the hook 102 with the first annular plate 9.

[0022] A second annular plate 11 and a sealing ring 14 are provided on the bottom plate 2. The sealing ring 14 is sleeved on the second annular plate 11. An annular groove 12 is provided on the second annular plate 11. An annular protrusion 13 is provided on the inner wall of the housing 3. The housing 3 is clamped with the second annular plate 11 and the annular protrusion 13 is placed in the annular groove 12.

[0023] The electric energy meter body 1 is sealed by providing a sealing ring 14 to prevent dust from entering the electric energy meter body 1 and causing damage to the electric energy meter body 1. At the same time, the annular protrusion 13 on the inner wall of the shell 3 is placed in the annular groove 12 on the second annular plate 11 for clamping, so that it can be further fixed on the base plate 2.

[0024] Working principle: When the electric energy meter needs to be disassembled, first squeeze the limit blocks 43 on both sides of the bottom plate 2, so that the limit blocks 43 extend into the first positioning groove 5, and at the same time, the limit blocks 43 squeeze the spring 42, so that the spring 42 contracts and generates elasticity, until the limit blocks 43 are disengaged from the second positioning groove 6, and then the connecting block 41 is disengaged from the storage space 7, and then the shell 3 is pulled out from the bottom plate 2, and at the same time, the annular protrusion 13 on the inner wall of the shell 3 is disengaged from the annular groove 12 on the second annular plate 11, and then the shell 3 is separated from the bottom plate 2, and then the electric energy meter body 1 is exposed, and finally the electric energy meter body 1 is pulled out from the first annular plate 9, and then the electric energy meter body 1 is separated from the bottom plate 2, and then the electric energy meter body 1 is disassembled.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
