[0002] In the existing technology of power transmission and distribution facilities, the busway series products are in a diversified development trend, while the traditional plug-in box operating mechanism or no operating handle outside the box, the cover of the plug-in box needs to be opened every time the switch is operated, and the operator is extremely Easy access to the electrical circuit inside the box, causing safety hazards
Or install the operating rotary handle on the door cover of the plug-in box. This method is only suitable for vertical installation of the bus duct and cannot meet the operational requirements of high-altitude erection and horizontal installation of the bus duct, and it is more laborious to operate the rotary handle

Embodiment Construction
[0012] As shown in the figure, when the present invention is closed, the operating handle 1 is pulled clockwise, and the operating handle drives the rotating shaft 3 to rotate around the fixed sleeve 4, and the actuating lever assembly 5 moves synchronously. Under the action of the rotating force of the toggle lever assembly, the toggle rocker arm bracket 6 rotates synchronously around the eccentric shaft 8 on the swing base 7 . Thereby promoting the molded case switch 9 to be in the closing position state, the upper and lower contacts of the switch are connected to complete the power-on requirement. When the plastic case switch is in the closing position, the indicator plate 2 outside the plug box points to the closing position nameplate.
[0013] When the brake is opened, the operating handle 1 is pulled counterclockwise, the operating handle drives the rotating shaft 3 to rotate around the fixed sleeve 4, and the actuating lever assembly 5 moves synchronously. Under the ac...

The invention provides a manual operation mechanism for a plug connection box. During switch-on and switch-off, an operating handle 1 is pulled; the operating handle drives a rotor shaft 3 to turn around a fixed sleeve 4; and a pull lever assembly 5 moves synchronously. Under the action of the torsional force of the pull lever assembly, a rocker arm support 6 is pulled to turn synchronously around an eccentric axis 8 on a vibrating bedplate 7, thereby pushing a plastic shell switch 9 in the switch-on position or the switch-off position and completing the power turn-on and the power turn-off actions. When the plastic shell switch is in the switch-on or switch-off position, an indicator 2 outside the plug connection box indicates the nameplate in the switch-on position or the switch-off position.
Description
technical field [0001] The invention relates to a manual operation mechanism of a plug box. Background technique [0002] In the existing technology of power transmission and distribution facilities, the busway series products are in a diversified development trend, while the traditional plug-in box operating mechanism or no operating handle outside the box, the cover of the plug-in box needs to be opened every time the switch is operated, and the operator is extremely It is easy to touch the electrical circuit in the box, causing a safety hazard. Or install the operating rotary handle on the door cover of the plug-in box. This method is only suitable for vertical installation of the bus duct and cannot meet the operational requirements of high-altitude erection and horizontal installation of the bus duct, and it is more laborious to operate the rotary handle. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a re...
