DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] See also Figure 1 , Figure 2 and Figure 3 The utility model provides an external electric operating mechanism of a ring network cabinet, including a body 1. A mounting frame 2 is arranged on the back of the body 1. The mounting frame 2 can be fixed on the ring network cabinet to realize the installation of the body 1 on the ring network cabinet, and the body 1 is connected to the ring network cabinet. The power switch of the ring network cabinet is realized by rotating a switch member 3 arranged at the front end of the body 1. A detachable knob 4 is arranged on the switch member 3.

[0023] See also Figure 2 , Figure 3 and Figure 4 The utility model provides an external electric operating mechanism of a ring main unit, wherein the detachable knob 4 comprises a knob body 41, the knob body 41 is connected to the switch member 3, and the opening where the knob body 41 is connected to the switch member 3 has the same shape as the switch member 3;

[0024] Example: If the switch member 3 is rectangular, the opening of the knob body 41 is also rectangular;

[0025] The knob body 41 has a second docking frame 401 integrally formed inside. The second docking frame 401 has the same shape as the switch member 3. When the knob body 41 is connected to the switch member 3, the switch member 3 will pass through the second docking frame 401, and the switch member 3 will also be connected to the docking frame 42 integrally formed inside the knob body 41. The second docking frame 401 can reduce the skew phenomenon of the switch member 3 when docking with the knob body 41, thereby improving the convenience of docking.

[0026] A docking rod 43 passes through the top of the knob body 41, and a fixing pad 402 is provided at the connection between the knob body 41 and the docking rod 43. The fixing pad 402 is used to prevent the docking rod 43 from being locked unstably due to the arc surface of the knob body 41 after being fixed. The docking rod 43 passes through the fixing pad 402. At the same time, when the docking rod 43 passes through the top of the knob body 41, it will be connected to the guide frame 403 integrally formed at the upper end of the knob body 41, and the docking rod 43 will pass through the guide frame 43, so that the docking rod 43 will not be skewed during docking;

[0027] The docking frame 42 and the switch member 3 are both provided with through holes 44. When the through holes 44 on the switch member 3 are aligned with the through holes 44 on the docking frame 42, the switch member 3 will abut against the inner surface of the knob body 41. The guide frame 403 and the through holes 44 on the docking frame 42 are in the same vertical line, so as to facilitate the docking of the docking rod 43. The docking rod 43 can easily pass through the through holes 44 on the docking frame 42 and the switch member 3. A screw 45 is integrally formed at the bottom of the docking rod 33. The screw 45 is threadedly connected with a threaded seat 46 arranged inside the knob body 41.

[0028] A spring 461 is provided inside the threaded seat 46, and a push piece 462 is provided at the end of the spring 461. When the screw rod 45 is fixed in the threaded seat 46, the push piece 462 fits with the end face of the screw rod 45, and can push the screw rod 45 after the screw rod 45 is locked, so that its thread fits with the internal thread of the threaded seat 46, thereby improving stability. A positioning rod 463 is provided in the middle of the push piece 462, and the positioning rod 463 penetrates the middle of the spring 461 and the bottom end face of the threaded seat 46, and the positioning rod 463 is slidably connected with the threaded seat 46, which can prevent the push piece 462 from being skewed;

[0029] When the knob body 41 is broken or damaged, the docking rod 43 is rotated to rotate the screw 45. Since the screw 45 is threadedly connected to the threaded seat 46, the screw 45 will move out of the threaded seat 46 when the screw 45 rotates. Then the docking rod 43 is slid out to release the docking frame 42 from being fixed on the switch member 3. Then the knob body 41 can be removed to achieve disassembly. This disassembly method is simple and has a stable structure. At the same time, the disassembly is quick. During installation, the knob body 41 is connected to the switch member 3, and then the docking rod 43 is passed through the top of the knob body 41, and then the docking rod 43 is passed through the docking frame 42 and the switch member 3 through the through hole 44. Then the docking rod 43 is rotated to lock the screw 45 in the threaded seat 46, and the installation is completed to achieve the beneficial effect of convenient installation.
