The rack of fixed plate connection, the rack is engaged with gear, and the gear is socketed with connecting rod, and case is stretched out in connecting rod one end
Body, the other end and cabinet wall are rotatablely installed, and one end of the connecting rod is provided with rocking bar, the casing away from support bar one
Side outer wall is installed with horizontally disposed handle, and it is fast that the casing is provided with card close to the side outer wall of the first fixed plate.
It is preferred that, ball, the through hole of first fixed plate are provided between the through hole of the fixed block and the first fixed plate
Interior to be provided with leak-proof device, the leak-proof device includes rubber ring and retainer ring.
It is preferred that, the tank wall rotational installation of the connecting rod and casing.
It is preferred that, the surface of the handle and rocking bar is equipped with antiskid thread.
It is preferred that, the outer ring of first fixed plate and valve shaft is fixedly mounted.
It is preferred that, the cross card is fitted close with cross neck soon, and one end of the fixed block is stretched out first and consolidated
Fixed board.
Compared with prior art, the beneficial effects of the invention are as follows：The structure of Handle of butterfly valve and valve shaft is carried out in the present invention
Improve, provided with gear and neck, when needing to use, handle is moved by gear and is connected with valve shaft, thus
The rotation of valve shaft can be controlled to open valve, abrasion of the handle to valve shaft is this construction reduce, making for valve shaft and handle is improved
With the life-span, it is to avoid handle to valve shaft control it is bad and produce leakage, it is to avoid occur leakage and produce security incident, to the person and
Enterprise brings safety guarantee.

Fig. 2 is a kind of overlooking the structure diagram of the mounting structure of handle Handle of butterfly valve and valve shaft proposed by the present invention.
In figure：1 first fixed plate, 2 fixed blocks, 3 necks, 4 valve shafts, 5 support bars, 6 second fixed plates, 7 racks, 8 gears,
9 connecting rods, 10 rocking bars, 11 casings, 12 handles, 13 fixture blocks.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.
Reference picture 1-2, a kind of mounting structure of handle Handle of butterfly valve and valve shaft, including the first fixed plate 1, the first fixed plate
Fixed block 2 is rotatablely equipped with 1, the inside of fixed block 2 offers neck 3, and the bottom of fixed block 2 is fixedly connected with valve shaft 4, the
One side of the fixed plate 1 away from valve shaft 4 is welded with support bar 5, and the one end of support bar 5 away from the first fixed plate 1 is provided with and the
The second parallel fixed plate 6 of one fixed plate 1, the lower section of the second fixed plate 6 be provided with casing 11, casing 11 be socketed with one end with
The rack 7 of second fixed plate 6 connection, the rack 7 is engaged with gear 8, and gear 8 is socketed with connecting rod 9, and the one end of connecting rod 9
Casing 11 is stretched out, the other end is connected with the inwall of casing 11, one end of the connecting rod 9 is provided with rocking bar 10, and casing 11 is away from branch
The side outer wall of strut 5 is installed with horizontally disposed handle 12, and casing 11 is installed close to the side outer wall of the first fixed plate 1
Have and ball is provided between card fast 13, the through hole of the fixed plate 1 of fixed block 2 and first, anti-neglected loading is provided with the through hole of the first fixed plate 1
Put, leak-proof device includes rubber ring and retainer ring, leak-proof device can prevent liquid from the through hole of the fixed plate 1 of valve shaft 4 and first
