Detailed ways

The embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings, but the following embodiments and accompanying drawings are only used to understand the present utility model, and cannot limit the present utility model. The present utility model can be defined and covered by claims implemented in different ways.

Fig. 1 shows a schematic structural view of a pressure plate fastener according to an embodiment of the present invention; Fig. 2a shows a schematic view of a side structure of a rotating sleeve according to an embodiment of the present invention; Schematic diagram of the cross-sectional structure of the rotating sleeve of the example.

As shown in Figure 1, Figure 2a and Figure 2b, the clamping plate fastener of the substation panel cabinet includes a knob sleeve 1. The fixed end 12 is provided with a rectangular groove 13, and also includes a blocking block 2 and a handle 3, wherein one end of the blocking block 2 is a hand-held end 21, and the other end is a protruding protruding end 22, which extends into the rectangular groove 13 and connects with the rectangular groove. 13, the handle 3 is wrapped around the outside of the knob sleeve 1 and the blocking block 2. In order to be easy to carry, the top of the handle 3 is provided with a hanging ring 4. Usually, the block 2 is made of PA66 plastic, and the handle 3 is made of V0 grade plastic, both of which are insulating materials, and the CTI (Current Tracking Index) of V0 grade plastic is greater than or equal to 600. That is, the insulation strength of the material is very high, and the safety factor is high.

Fig. 3a shows a schematic top view of a block according to an embodiment of the utility model; Fig. 3b shows a schematic diagram of a front view of a block according to an embodiment of the utility model; Fig. 3c shows a schematic diagram of a block according to an embodiment of the utility model Schematic diagram of the cross-sectional structure of the blockage.
