Specific embodiment
The application is described further in the following with reference to the drawings and specific embodiments, so that those skilled in the art can be with
It more fully understands the application and can be practiced, but illustrated embodiment is not as the restriction to the application.
As shown, the blocking device includes the first closing piece this application provides a kind of air switch blocking device
1, the second closing piece 2, the blocking device further include a screw rod 3, and the one end of the screw rod 3 is fixed on second lock
On block 2, first closing piece 1 is provided with a mounting hole passed through for the screw rod 3, the other end of the screw rod 3
Across the mounting hole, a nut 4 is also threaded on the screw rod 3, the nut 4 is located at first lock
The side far from second closing piece 2 of block 1, first closing piece 1 and the second closing piece 2, which are respectively arranged with, to be oppositely arranged
First latch hook 11 and the second latch hook 21.A spring 5 is also arranged on the screw rod 3, the spring 5 is located at the first closing piece 1
Between second closing piece 2, one end of the spring 5 acts on first closing piece 1, the spring 5 it is another
One end acts on second closing piece 2.The one end far from second closing piece 2 of the screw rod 3 is additionally provided with head
Portion 31, the diameter on the head 31 are greater than the diameter of the screw rod 3.The screw rod 3 passes through with second closing piece 2
The mode of threaded connection is mutually fixedly connected.A lockhole 32 is additionally provided on the screw rod 3, the blocking device, which has, unlocks
State and blocking, when the blocking device is in unlocking condition, the lockhole 32 is located at first closing piece 1
