Embodiment
More fully example embodiment is described referring now to accompanying drawing.But example embodiment can be implemented in a variety of forms, and should not be understood to be limited to mode of execution set forth herein; On the contrary, provide these mode of executions to make the utility model more comprehensively with complete, and the design of example embodiment is conveyed to those skilled in the art all sidedly.
As shown in Figure 4, be the erection drawing of ball valve shutter in the utility model.
The structure of ball valve shutter comprises: swing arm 41, first bearing pin 42, base 43, second bearing pin 44, gear 45 and rack gear arrangement 46.
As shown in Figure 5, be the plan view of base 43 in the utility model; As shown in Figure 6, be the right elevation of base 43 in the utility model.
The structure of base 43 comprises: pedestal 431, herringbone connecting rod 432, pedestal crossbeam 433, first pin shaft hole 434; The end winding support of two herringbone connecting rods 432 is on pedestal 431, and pedestal crossbeam 433 two ends are fixed on pedestal 431, and the first pin shaft hole 434 opens the bending part at herringbone connecting rod 432.Pedestal crossbeam 433 can strengthen the intensity of base 43.
As shown in Figure 7, be the structural drawing of swing arm 41 in the utility model.
The structure of swing arm 41 comprises: bar head 411, the body of rod 412, first swing arm through hole 413, second swing arm through hole 414; Bar head 411 is arranged on the end of the body of rod 412, and bar head 411 is provided with lengthening attachment hole; First swing arm through hole 413 and the second swing arm through hole 414 are arranged on the body of rod 412, first swing arm through hole 413 is positioned at below bar head 411 near middle position, second swing arm through hole 414 is positioned at the below of the first swing arm through hole 413, near another end of bar head 411.
