Long door bolt push rod 5 is inserted in the hole of switch press plate 6, so as to play the role of guiding, reset, control travel switch pressing plate 6.
Specific work process is as follows：
1）It opens the door：Spring operating mechanism 22 is located at the top of the utility model, using operation lever by spring operating mechanism 22
Get to earthing position, the cam in mechanism no longer compresses ground connection door bolt push rod cup 7, under the action of door bolt resetting spring 9 is grounded,
Ground connection door bolt push rod 8 is moved upwards along ground connection door bolt push rod guide sleeve 18, drives ground connection door bolt push rod cup 7 and travel switch pressing plate
6 move upwards, until ground connection door bolt push rod cup 7 is contacted with the cam short side on spring operating mechanism 22；At this point, ground connection door bolt pushes away
Bar 8 departs from the ground connection door bolt push-rod hole 24 of Xiamen 21, and travel switch is in the raw.
Chain 2 handle of baffle is grasped up to carry, drive chain 1 baffle of stent, door bolt stent 3, elastic cylindrical pin 4,
Long door bolt push rod 5 and hatch pin push rod 13 are moved upwards along door bolt push rod guide sleeve 14；When door bolt stent 3 reaches certain position,
Chain buckle 15 is under the action of chain buckle reduction torsion spring 16, and chain buckle 15 moves out, its notch just props up door
Pin support 3 forces it that cannot move downward, and locks the position；Long door bolt push rod 5 and hatch pin push rod 13 also depart from Xiamen 21
Long door bolt push-rod hole 23 and hatch pin push-rod hole 25, Xiamen 21 can smooth opening at this time.
2）It closes the door：Spring operating mechanism 22 is in earthing position, and Xiamen 21 is pushed into cabinet, Xiamen forward edge and Xiamen
Chain button plectrum 12 contacts, and exerts oneself slightly forward, and the chain button plectrum 12 in Xiamen is around 17 clockwise movement of pin bolt；The chain button in Xiamen
12 top edge of plectrum is contacted with chain 15 lower edge of buckle, chain buckle 15 is forced to be rotated counterclockwise around pin bolt 17, chain button
Plate 15 is not propping up door bolt stent 3；Door bolt stent 3 is answered from the effect of chain 15 upward power of buckle in gravity and door bolt push rod
Under the action of the spring 19 of position, long door bolt push rod 5 and hatch pin push rod 13 are moved downward along door bolt push rod guide sleeve 14, drive chain branch
Frame baffle 1, chain baffle 2, door bolt stent 3 and elastic cylindrical pin 4 move downward.Long door bolt push rod 5 and hatch pin push rod 13 divide
Not Cha Ru Xiamen 21 long door bolt push-rod hole 23 and hatch pin push-rod hole 25, realize that Xiamen is chain, do not carry chain baffle 2 above at this time
Xiamen 21 can not just be opened；
3）It is grounded chain：In spring operating mechanism 22 when carrying out ground connection separating brake, the long edge of cam in mechanism starts to connect
Ground door bolt push rod cup 7 contacts, it is forced to move downward, and ground connection 7 drive travel switch pressing plates 6 of door bolt push rod and ground connection door bolt push away
Bar 8 moves downward；Ground connection door bolt push rod 8 is moved along ground connection 18 guide sleeve of door bolt push rod, and travel switch pressing plate 6 is pushed away in ground connection door bolt
It under the action of head 7, long door bolt push rod 5, is moved along specific direction, reaches final position and push down travel switch, export electric signal,
Judge the position of the switch.Ground connection door bolt push rod 8 can be inserted into the ground connection door bolt push-rod hole 24 of Xiamen 21, whether above carry chain baffle at this time
2, Xiamen 21 can not be all opened, it is chain to realize that Xiamen 21 is grounded.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, several improvement and deformation can also be made, these change
The scope of protection of the utility model is also should be regarded as into deformation.
