Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof.
Referring to fig. 1 to 2, in a specific embodiment, the direct-acting grounding switch provided by the present invention includes a cabinet body, a pair of guide plates 2 perpendicular to the bottom of the cabinet body is disposed in the cabinet body, a sliding plate 1 is sleeved on each of the two guide plates 2, and an upper end of the sliding plate 1 extends upward out of the cabinet body.
The top of slide 1 is connected with horizontal mounting panel 10, install a plurality of ground contact 11 on the mounting panel 10.
The sliding plate 1 can slide up and down along the corresponding guide post 2, so that the switching on/off of the direct-acting grounding switch is realized. Specifically, the method comprises the following steps: when the sliding plate 1 slides upwards to a first limit position, a moving contact and a fixed contact which are arranged in the cabinet body are contacted, and the direct-acting grounding switch is switched on; when the sliding plate slides downwards to a second limit position, the moving contact and the static contact which are arranged in the cabinet body are separated, and the direct-acting grounding switch is switched off.
In this embodiment, the internal horizontal pivot 6 that is equipped with of cabinet, the one end of pivot 6 link in on a lateral wall of the cabinet body, the other end link of pivot 6 is in on another lateral wall of the cabinet body, be connected with between the lower extreme of two slide 1 with the connecting rod 3 that pivot 6 is parallel, pivot 6 with be connected with a pair of crank 4 between the connecting rod 3. The lower end of the crank 4 is sleeved on the rotating shaft 6, the upper end of the crank 4 is sleeved on the connecting rod 3, and when the rotating shaft 6 rotates, the rotating torque is transmitted to the connecting rod 3 through the crank 4, so that the sliding plate 1 is driven to slide up and down, and the switching-on/off of the direct-acting grounding switch is realized.
In this embodiment, the rotating shaft 6 may be driven to rotate in two modes, i.e., a manual mode and an automatic mode, so as to implement switching on/off of the grounding switch, wherein: one end of the rotating shaft 6 is connected with a crank arm 7, and the rotating shaft 6 can be driven to rotate in a manual mode by shaking the crank arm 7; the cabinet is internally provided with a driving motor 8, the rotating shaft 6 is sleeved with a gear 9, an output shaft of the driving motor 8 is meshed with the gear 9, and the driving motor 8 is driven by the gear 9 to rotate the rotating shaft 6.
