DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figure 2 and Figure 3 As shown, in this embodiment, a remote control operating mechanism inside a DC cabinet includes multiple switches 2 and a DC cabinet body 1, characterized in that: the operating handles of the multiple switches 2 are all equipped with a driving component 4, and the multiple switches 2 are all fixedly installed inside the DC cabinet body 1. The driving component 4 includes a connecting sleeve 401 sleeved on the outside of the operating handle of the switch 2, and a mounting sleeve 402 is rotatably sleeved on the outside of the connecting sleeve 401. A telescopic rod 403 is fixedly connected to an outer wall on one side of the mounting sleeve 402, an electric telescopic rod 404 is fixedly installed on one side of the bottom outer wall of the telescopic rod 403, and an extension plate 405 is fixedly installed on the bottom outer wall of the electric telescopic rod 404.

[0023] The connecting sleeve 401 is put on the outside of the operating handle of the switch 2, and then reinforced with bolts 406, and finally the electric telescopic rod 404 is installed on the top of the extension plate 405 to complete the installation. The process of pushing up the operating handle is: the electric telescopic rod 404 is started, and its output end drives the telescopic rod 1 403 to move upward, and the telescopic rod 1 403 can drive the operating handle of the switch 2 to flip upward through the connecting sleeve 401 and the installation sleeve 402. Since the connecting sleeve 401 and the installation sleeve 402 are rotatably connected, the flipping process of the operating handle can be guaranteed not to be hindered, and the existence of the telescopic rod 1 403 can adapt to the change of the horizontal position of the operating handle, so that the driving process can proceed smoothly.

[0024] like Figure 2 and Figure 4 As shown, a fixing component 3 is installed on the outside of each of the multiple switches 2, and the fixing component 3 includes a fixing frame 301 that is slidably mounted on the outside of the switch 2, and a mounting groove 302 is opened on both sides of the fixing frame 301, wherein a screw rod 303 is rotatably connected inside one of the mounting grooves 302, and a limit rod 304 is fixedly connected inside the other mounting groove 302, and an extrusion plate 305 is threadedly connected to the outside of the screw rod 303, one end of the extrusion plate 305 is slidably mounted on the outside of the limit rod 304, and one end of the extension plate 405 is fixedly connected to the outer wall of one end of the fixing frame 301.

[0025] The fixing frame 301 is put on the outside of the switch 2, and then the screw rod 303 is driven to rotate inside the installation groove 302 through the knob 306. The extrusion plate 305 restricted by the limit rod 304 will be driven by the screw rod 303 to move downward until the extrusion plate 305 is tightly squeezed on the top of the switch 2. At this time, the fixing component 3 is also firmly fixed on the outside of the switch 2, making the assembly and disassembly process simple enough.

[0026] like Figure 3 As shown, a plurality of bolts 406 are threadedly connected to the top of the connecting sleeve 401, and the plurality of bolts 406 are in contact with the operating handle of the switch 2. Under the action of the friction between the bolts 406 and the operating handle, the connection between the connecting sleeve 401 and the operating handle can be ensured to be more stable.

[0027] like Figure 2 As shown, a knob 306 is rotatably connected to one side of the bottom outer wall of the fixed frame 301, and the knob 306 and one end of the screw rod 303 are coaxially fixed, which can increase the transmission force arm, thereby making the driving process easy enough.

[0028] like Figure 3 As shown, the connection sleeve 401 , the installation sleeve 402 and the plurality of bolts 406 are all made of insulating materials, which effectively prevents the current leaking from the switch 2 from being transmitted to the electric telescopic rod 404 through the three.

[0029] As shown in FIG. 4 , the lead angle of the screw rod 303 is smaller than the equivalent friction angle, so that the screw rod 303 has a self-locking property, thereby preventing the position of the extrusion plate 305 from changing with use.

[0030] The utility model provides a remote control operation mechanism inside a DC cabinet, and the specific working principle is as follows:

[0031] When installing the operating mechanism, first put the fixing frame 301 on the outside of the switch 2, then drive the screw rod 303 to rotate inside the installation groove 302 through the knob 306, and the extrusion plate 305 restricted by the limit rod 304 will be driven by the screw rod 303 to move downward until the extrusion plate 305 is tightly squeezed on the top of the switch 2. At this time, the fixing component 3 is also firmly fixed on the outside of the switch 2, making the assembly and disassembly process simple enough. Then put the connecting sleeve 401 on the outside of the switch 2 operating handle, and then use the bolt 406 to reinforce it. Finally, the electric telescopic rod The installation can be completed by installing 404 on the top of the extension plate 405. The process of pushing the operating handle upward is: the electric telescopic rod 404 is started, and its output end drives the telescopic rod 1 403 to move upward. The telescopic rod 1 403 can drive the operating handle of the switch 2 to flip upward through the connecting sleeve 401 and the mounting sleeve 402. Since the connecting sleeve 401 and the mounting sleeve 402 are rotatably connected, the flipping process of the operating handle can be guaranteed to be unobstructed, and the existence of the telescopic rod 1 403 can adapt to the change of the horizontal position of the operating handle, so that the driving process can proceed smoothly.
