Specific implementation mode
With the drawings and specific embodiments, the present invention is described in further detail below.
As shown in Figure 2, Figure 3, Figure 4, a kind of locking device of outlet valve, the locking device include being mounted on valve seat 10
Mounting base 1, open up opening type groove in the mounting base 1, which is arranged spring 2, and connection lock core connects on spring 2
Bar 3, lock core connecting rod 3 are vertically connected with lock core 4；The locking device further includes ∠ types connection grab 5, which connects grab 5
One end be fixed on machine casing 7, the other end is connected with release tab 6, and the corners of ∠ types connection grab 5 arrives and machine
The bevel edge of the connected one end of device shell is contacted with lock core connecting rod 3, when release tab 6 is pressed, the wedge angle of the ∠ types connection grab 5
Spring 2 is inwardly compressed along opening type groove in the bevel edge pushing lock cylinder connecting rod 3 of portion to the one end that is connected with machine casing, to movable lock core
4 movement unlocks.
Circular hole 8 is set on the machine casing 7, and one end of ∠ types connection grab 5, which is inserted into the circular hole 8, to be fixed.
U-shaped card slot 9 is set on the release tab 6, the other end of ∠ types connection grab 5 be inserted into the U-shaped card slot 9 into
Row is fixed.
A strip hole can be also opened up in heretofore described mounting base 1, the strip is stretched out in one end of the lock core connecting rod 3
Hole, and lock core connecting rod 3 is made to be limited to movement in the strip hole.
The present invention provides a kind of valve locking device of the one-touch unlock of Fast Installation so that convenient when dismounting installation outlet valve
Succinctly.Fig. 1 is outside the appearance equipped with outlet valve and its release tab, release tab and 11 profile of outlet valve and lung ventilator
See perfect adaptation, beautiful coordination.Fig. 2 is outlet valve mounted state.The mounting base of locking device is fixed on valve seat at this time
On, spring and lock core are mounted on inside mounting base, and spring, which is compressed, awards the power of lock core one to the left so that lock core top is stuck in
