Safety.
2, the utility model can be after cabinet door closing, valve plate energy automatic homing.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model embodiment.
Specific embodiment
Below with reference to specific drawings and examples, the utility model is described in further detail.
In Fig. 1, including mandril 1, press spring base 2, pressure spring 3, retaining ring 4, second bearing seat 5, pivot pin 6, slide plate 7, shaft 8 are surveyed
Template 9, valve plate 10, guide rail 11, first bearing seat 12,3rd bearing seat 13,
As shown in Figure 1, the flame-proof switch device valve mechanism in embodiment, is equipped on flame-proof switch device interior plate
First bearing seat 12, press spring base 2, second bearing seat 5, guide rail 11 and 3rd bearing seat 13, first bearing seat 12 and second bearing
Seat 5 is respectively arranged with linear bearing, and 3rd bearing seat 13 is equipped with deep groove ball bearing, and mandril 1 utilizes first bearing seat 12 and the second axis
It holds seat 5 to be slidably mounted on interior plate, mandril 1 is parallel to interior plate, and 2 one end of press spring base connects retaining ring 4, and retaining ring 4 is used to limit
The inside side plate left-hand of pressure spring 3 movement in press spring base 2, the pressure spring 3 in press spring base 2 be located at retaining ring 4 and mandril 1 step surface it
Between, for realizing the automatic homing of valve plate, shaft 8 is vertically rotatably installed on interior plate using 3rd bearing seat 13, shaft 8
Below the end of mandril 1, it is fixedly connected with slide plate 7 and rocker arm 9 in shaft 8, has angle between slide plate 7 and rocker arm 9.Slide plate
Long hole is had on 7, pivot pin 6 is set on mandril 1, and pivot pin 6 can slide in slot hole, and slide plate 7 is mutual by pivot pin 6 and mandril 1
Connection.Valve plate 10 is slidably fitted on guide rail 11, valve plate 10 can slide up and down on guide rail 11, and movable plate 10 is insulation
Plate can preferably protect operator.Elongated slot is arranged in the end of valve plate 10, and the end of rocker arm 9 is located in the elongated slot, living
Door-plate 10 can move up and down under the drive of rocker arm 9, realize the function of the charging zone of breaking-off contact.
The specific installation applicable cases of the utility model are as follows：
The utility model when flame-proof switch is opened, turn left in first bearing seat 12 and second bearing seat 5 from the right side by mandril 1
Sliding, pressure spring 3 generate the trend moved downward as the step surface of mandril 1 is moved to the left, generate bullet because of the limit of block 4
Property deforms and has pretightning force to the right, and the pin shaft 6 of 1 one end of mandril slides in the long hole of slide plate 7, thus drive slide plate 7 with
