The second limiting plate 49 is used to limit the maximum rotation angle of the first connecting rod 43 rotating in the other direction, when the second limiting plate 49 is in contact with the first connecting rod 43, the first connecting rod 43 is in the second position.

[0034] At the same time, the second limiting plate 49 and the first limiting plate 48 have an included angle greater than 90°, so that the included angle between the first connecting rod 43 and the horizontal plane is greater than 90° when the first connecting rod 43 is in contact with the second limiting plate 49, reducing the rotation of the first connecting rod 43 in the direction of separating from the cabinet body 2 when the box 3 is placed in the cabinet body 2.

[0035] The mounting plate 41 comprises a base plate 411 and a connecting plate 412 connected to the base plate 411, one end of the first connecting rod 43 and the second connecting rod 44 is mounted on the connecting plate 412, a fixing piece 413 is connected between the connecting plate 412 and the side plate 21, the fixing piece 413 is above the connecting plate 412, the fixing piece 413 connects the connecting plate 412 and the side plate 21, so that part of the weight of the box 3 is transmitted to the cabinet body 2, improving the installation stability of the box 3 in the cabinet body 2, and the first limiting plate 48 and the second limiting plate 49 are mounted on the connecting plate 412.

[0036] The parallel arrangement of the first connecting rod 43 and the second connecting rod 44 can ensure that the first connecting rod 43 and the second connecting rod 44 maintain consistent motion trajectories and speeds during motion, the rotational motion of the first connecting rod 43 and the second connecting rod 44 is converted into stable downward pulling operation and pushing upward retracting operation of the box 3, the height of the box 3 on the workbench 1 can be adjusted, the size specifications of the first connecting rod 43 and the second connecting rod 44 can be selected according to the actual size of the cabinet body 2, and the convenience of use is ensured.

[0037] In order to facilitate the pulling of the box 3, connecting pieces 46 are hingedly connected to the two sides of the box 3, one end of each connecting piece 46 is connected to a handle 47, and the handle 47 can be operated to quickly realize the pulling of the box 3.

[0038] When the electric appliance element metering device is installed and maintained, adjusted, and replaced, the staff can pull the handle 47 to apply an external force to the box 3, the hinge point of the first connecting rod 43 on the box 3 rotates, and the hinge point of the first connecting rod 43 on the mounting plate 41 rotates. Since the hinge points of the first connecting rod 43 and the second connecting rod 44 are both on the mounting plate 41, the hinge points of the second connecting rod 44 on the box 3 and the mounting plate 41 both rotate, and the first connecting rod 43 rotates to the first limiting plate 48 to reach the maximum limit, that is, the box 3 can be stably pulled out to the outside of the cabinet 2. In this embodiment, since the box 3 stores the electric appliance element metering device related to the electric appliance element metering device, the hinge shafts of the first connecting rod 43 and the second connecting rod 44 are both damping shafts, which provide damping for the movement of the first connecting rod 43 and the second connecting rod 44, effectively slow down the speed of the box 3 being pulled down or pushed up, and can realize the hovering of the box 3 at any suspended position for convenient maintenance and installation operation.

[0039] When the box 3 is pulled out to the outside of the cabinet 2 and the electric appliance element metering device is installed, the operator applies an external force to the box 3 to the inside of the cabinet 2, the hinge point of the first connecting rod 43 on the box 3 rotates, the hinge point of the first connecting rod 43 on the mounting plate 41 rotates, and the hinge points of the second connecting rod 44 on the box 3 and the mounting plate 41 both rotate with the rotation of the first connecting rod 43.

In this embodiment, in order to improve the stability of the box 3 when placed in the cabinet 2, a weighing plate is arranged between the two side plates 21. When the box 3 is pushed into the cabinet 2, the bottom of the box 3 abuts against the weighing plate. Since the movement track of the box 3 is a parabola, the width of the weighing plate is set according to the size of the box 3, and the movement of the box 3 does not interfere with the weighing plate during the pulling process. Embodiment Two

[0040] Reference Figure 5 and Figure 6The difference of the meter box quick push-pull mechanism of the electric energy meter calibration device in the embodiment is that a buffering assembly 42 is arranged on the connecting plate 412. The buffering assembly 42 comprises a telescopic rod 421 and a sleeve 422. One end of the telescopic rod 421 is connected with the second connecting rod 44, and the other end of the telescopic rod 421 is sleeved in the sleeve 422. An elastic element 423 is arranged in the sleeve 422. One end of the elastic element 423 is connected with the sleeve 422, and the other end of the elastic element 423 is connected with the telescopic rod 421. The end of the sleeve 422 is rotationally connected with the connecting plate 412. The arrangement of the elastic element 423 forces the telescopic rod 421 to always have a movement trend of extending out of the sleeve 422. In turn, when the box body 3 is pulled out of the cabinet body 2, the telescopic rod 421 compresses the elastic element 423 to achieve a buffering effect. When the box body 3 is pushed into the cabinet body 2, the elastic element 423 drives the telescopic rod 421 to extend out to provide a certain locking force for the second connecting rod 44, thereby improving the stability of the box body 3 placed in the cabinet body 2. In the embodiment, the elastic element 423 is a spring, and a rubber elastic element can also be used.

[0041] The second connecting rod 44 is hingedly connected with a third connecting rod 45 at one end. The other end of the third connecting rod 45 is rotationally connected with one end of the telescopic rod 421. The movement of the second connecting rod 44 is driven to the telescopic rod 421 through the third connecting rod 45, thereby improving the flexibility of the telescopic rod 412 when extending and retracting.

[0042] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
