[0016] Example 1 See also Figure 1-Figure 3 In this embodiment, the plug-in electric energy meter assembly and disassembly tool includes a fixing unit 10, an adjustment unit 20 and an operation unit 30, wherein the fixing unit 10 also includes two square tubes 11 arranged in parallel, and connecting columns 12 with square cross-sections can be slidably inserted at both ends of the square tube 11, and a clamping plate 13 is fixed to the outer end of the connecting column 12, and the clamping plate 13 moves synchronously with the connecting column 12. A sliding groove 111 is opened on the outer side wall of the square tube 11, and the sliding groove 111 extends along the longitudinal direction of the square tube 11 as a whole. A limiting rod 121 slidably engaged with the sliding groove 111 is fixed on the connecting column 12. As an example, the connecting column 12 is symmetrically arranged at both ends of the square tube 11.

[0017] In addition, the fixing unit 10 also includes a connecting tube 14 vertically fixed to the middle part of the square tube 11, a slider 15 is slidably inserted in the connecting tube 14, a clearance groove 141 is opened on the outer wall of the connecting tube 14, and the clearance groove 141 extends along the longitudinal direction of the connecting tube 141 as a whole. Pins 151 are fixed to the slider 15 with upper and lower intervals, and the pins 151 can be slidably engaged in the clearance groove 141. A transmission plate 16 is hinged between the limit rod 121 and the pin 151 located at the bottom, and the adjustment unit 20 is hung on the pin 151 located at the top.

[0018] In this embodiment, the adjusting unit 20 includes a support beam 21 suspended above the fixed unit 10, the support beam 21 is arranged vertically with the square tube 11, and both ends of the support beam 21 are fixedly connected with swing arms 22 hinged to the connecting tube 14. The lower end of the swing arm 22 is constructed with a V-shaped limit groove 23, and the two side walls of the limit groove 23 are symmetrically arranged on both sides of the swing arm 22. The pin 151 located above the slider 15 can be slidably hung in the limit groove 23.

[0019] It should be understood that when the swing arm 22 is driven to swing by the support beam 21, the limit slot 23 as a whole swings along with the swing arm 22. At this time, the side wall of the limit slot 23 can generate an upward driving force on the pin column 151 hung therein, thereby driving the slider 15 to move up and down, and then pulling the connecting column 12 into the square tube 11 through the transmission plate 16, so that the clamping plates 13 at both ends of the square tube 11 can move in opposite directions, so that the clamping plates 13 are clamped on the front and rear ends of the meter base 50, thereby realizing a fixed connection between the fixing unit 10 and the meter base 50.

[0020] It should also be understood that, since the pin 151 is hung at the lowest point of the V-shaped limit groove 23 in this state, and the two side walls of the limit groove 23 are symmetrically arranged on both sides of the swing arm 22, the swing arm 22 can achieve a fixed connection between the fixing unit 10 and the meter base 50 when swinging to the left or right, that is, when installing or removing the plug-in electric energy meter 40, the fixing unit 10 can be clamped and fixed to the meter base 50.

[0021] In this embodiment, the operating unit 30 includes two parallel connecting plates 31 and a push rod 32 fixed between the two connecting plates 31. The connecting plates 31 are arranged vertically with the support beam 21. A mounting groove 311 is opened on the connecting plate 31 along the longitudinal direction of the connecting plate 31. The support beam 21 is inserted into the mounting groove 311. The push rod 32 is arranged vertically with the connecting plates 31, and the push rod 32 is arranged symmetrically at both ends of the connecting plate 31.

[0022] It should be noted that the operating unit 30 is constructed as a rectangular frame as a whole. The operating unit 30 as a whole can swing around the support beam 21. At the same time, the support beam 21 can slide relatively inside the mounting groove 311, so that the vertical distance between the two push rods 32 and the support beam 21 is adjustable, that is, when the operating unit 30 swings to push the plug-in electric energy meter 40 to move, the length of the force arm is adjustable.

[0023] Optionally, in order to avoid crushing the plug-in electric energy meter 40 , a rubber sleeve is provided on the outside of the push rod 32 .

[0024] The fixing unit 10 includes a retractable card plate, the adjusting unit is hinged on the fixing unit and is transmission-connected to the card plate, the operating unit is swingably arranged on the adjusting unit, and the operating unit is configured to push the plug-in electric energy meter to move after driving the adjusting unit to swing so that the card plate clamps the meter base.

[0025] It should be noted that the plug-in electric energy meter 40 in this embodiment is a prior art, and the plug-in holes 41 on the plug-in electric energy meter 40 and the plugs 51 on the electric meter base 50 are arranged in a one-to-one correspondence.

[0026] When installing the plug-in electric energy meter 40 on the electric energy meter base 50, first place the plug-in electric energy meter 40 in the card slot on the electric energy meter base 50, and make the plug-in hole 41 and the plug 51 face each other, then place the two square tubes 11 on both sides of the electric energy meter base 50, and then adjust the relative position of the operating unit 30 on the support beam 21 so that the push rod 32 can abut against the upper end of the plug-in electric energy meter 40, and then swing the operating unit 30 with the aforementioned push rod 32 as a pivot. At this time, the support beam 21 will swing under the push of the operating unit 30, and can make the card plate 13 on the fixing unit 10 clamped on the electric energy meter base 50, and then, the support beam 21 will remain fixed, and at this time, the operating unit 30 will swing with the support beam 21 as a pivot, thereby pushing the plug-in electric energy meter 40 toward the plug 51, and completing the installation work.

[0027] When the plug-in electric energy meter 40 is removed from the electric energy meter base 50 , the principle is the same as above, except that the push rod 32 is now in contact with the lower end of the plug-in electric energy meter 40 .

[0028] The present application promotes the movement of the plug-in electric energy meter by swinging the operating unit around the adjusting unit, and utilizes the lever principle to make the assembly and disassembly of the plug-in electric energy meter more labor-saving. Moreover, the operating unit can also maintain the automatic clamping state of the fixing unit on the base of the electric energy meter through the adjusting unit during the process of pushing the plug-in electric energy meter to move. The application has a wide range of uses and is easy to operate.

[0029] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
