Summary of the invention
The purpose of this utility model is to provide a kind of flame-proof switch device valve mechanisms, can overcome and exist in the prior art Deficiency, and structure is simple, and components are few, reliable in action.
According to technical solution provided by the utility model:Flame-proof switch device valve mechanism, it is characterised in that:In Anti-breakage It closes and first bearing seat, second bearing seat, guide rail and 3rd bearing seat is installed on device interior plate, mandril utilizes the first axle It holds seat and the second bearing seat is slidably mounted on the interior plate, including shaft is using 3rd bearing seat rotational installation On side plate;Slide plate and rocker arm are fixedly connected in the shaft, the slide plate is flexibly connected with mandril, the company of sliding on the guide rail It takes over a job door-plate, the end of the valve plate is flexibly connected with the end of rocker arm.
Press spring base, the pressure are installed on flame-proof switch device interior plate as a further improvement of the utility model, Spring abutment one end connects retaining ring, is equipped with pressure spring in the press spring base, pressure spring be located at the retaining ring and the mandril step surface it Between.
The movable plate is insulation board as a further improvement of the utility model,.
The mandril is parallel to the interior plate as a further improvement of the utility model, and the shaft is perpendicular to institute Interior plate is stated, and the shaft is located at below the end of the mandril.
Long hole is had on the slide plate as a further improvement of the utility model, pivot pin is set on the mandril, it is described Pivot pin can slide in the long hole.The slide plate is connected with each other by pivot pin and mandril.
There is angle between the slide plate and rocker arm as a further improvement of the utility model,.
Elongated slot, the end position of the rocker arm is arranged in the end of the valve plate as a further improvement of the utility model, In in the elongated slot;The valve plate can move up and down under the drive of the rocker arm.
The utility model compared with prior art, has the following advantages that:
1, the utility model when the door is opened it can automatic breaking-off contact charging zone, to guarantee staff's person 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 Shaft 8 rotates counterclockwise for axle center, and the rocker arm 9 being fixedly connected in shaft 8 with sliding block 7 is driven to do counterclockwise also with shaft 8 Rotation, while the end of rocker arm 9 is also slided in the elongated slot of 10 end of valve plate, makes valve plate 10 along the straight line side of guide rail 11 It is moved in yearning, thus the charging zone of breaking-off contact.When flame-proof switch unclamps, preload that pressure spring 3 is generated by flexible deformation The step surface of force pushing mandril 1 moves right mandril 1, so that slide plate 7, rocker arm 9 be driven to rotate clockwise, realizes valve plate Automatic homing.
