Detailed Description

The invention will be further described by way of examples with reference to the accompanying drawings:

as shown in fig. 1-6, a knob type cover plate for facilitating maintenance of a generator, the cover plate 1 is used for shielding a maintenance hole 2a formed in a generator housing 2, at least one clip 1a is disposed at an edge of the cover plate 1, and a notch 2b for facilitating the clip 1a to be inserted is disposed at a position corresponding to the clip 1a on the maintenance hole 2 a. The structure is the prior art and is not described herein again, the knob hole 1b is formed in the cover plate 1 at a position opposite to the clip 1a, the knob 3 and the knob seat 4 are arranged in the knob hole 1b, and the knob 3 penetrates through the knob hole 1b from outside to inside and is fixed on the knob seat 4.

A pressing block 4a is arranged on the rotary seat 4, a first limiting protrusion 2c is arranged on the inner side of the maintenance hole 2a, a second limiting protrusion 1c is arranged on the inner side of the cover plate 1, the first limiting protrusion 2c and the second limiting protrusion 1c are used for limiting the pressing block 4a, the pressing block 4a rotates along with the rotation of the knob 3 when the knob 3 is screwed, when the pressing block 4a is in contact with the first limiting protrusion 2c, the pressing block 4a is pressed on the inner side of the maintenance hole 2a at the moment, the cover plate 1 is installed on the generator shell 2 and is in a closed state, and when the pressing block 4a is in contact with the second limiting protrusion 1c, the pressing block 4a is not pressed on the inner side of the maintenance hole 2a at the moment, and the cover plate 1 can be easily disassembled and is in an open state.
