Action process: install the device on the door frame, and set a toggle block on the moving door. Assume that initially, the slider 8 and the toggle hook 81 are located in the middle of the housing 1, that is, in the middle of the two dampers. At this time, the damper Neither the damping tube nor the spring is stretched, the left guide slide part 33 on the left linkage hook 31 turns into the left linkage hook inflection point groove 12, and the right guide slide part 63 of the right linkage hook 61 turns into the right linkage hook inflection point in slot 14. In order to allow the shifting block on the moving door to enter into the shifting groove 86 and toggle the toggle hook 81, the shifting block will extrude the left elastic hook 84 or the right elastic hook 85 to make it retract in the housing 1, and the shifting block will Can slide into the toggle groove 86. When the door slides to the right, the toggle block toggles the right elastic hook 85, so that the toggle hook 81 moves to the right, and the slider 8 is driven to move to the right. At this time, the left toggle portion 82 leans against the first right wall 36 side, turn the left linkage hook 31 to make the left sliding part 33 turn out from the inflection point groove 12 of the left linkage hook, the left linkage block 3 moves to the right, and pulls the damping tube and the left elastic part of the left damper 2 4 stretch until the toggle hook 81 moves to the right toggle hook inflection point groove 15, the right guide column 88 on the toggle hook 81 slides into the right toggle hook inflection point groove 15, and the slider 8 will no longer be able to move. At this time, the right elastic Hook 85 turns downwards, and right elastic hook 85 is no longer blocking shifting block, and mobile door can continue to walk like this. When the movable door moved to the left again, the shifting block directly entered the toggle groove 86, and the shifting block moved the left elastic hook 84 to make the shifting hook 81 rotate, and the right guide sliding column 88 turned out from the right shifting hook inflection point groove 15. In the chute 11, the right elastic hook 85 rotates up again, and the slider 8 moves to the left. At this time, the left toggle part 82 is still in the left linkage toggle groove 34, and the first left wall 35 will be toggled to make the left linkage block 3 Move to the left, the damping tube of the left damper 2 and the left elastic piece 4 retract, and the left elastic piece 4 can help the damping tube reset. At this time, under the action of no external force, the moving door can move to the left with the help of the left elastic piece 4 Move, when the toggle hook 81 moves to the middle of the housing 1, the movable door moves in place, when the movable door continues to be pushed to move to the left, the slider 8 continues to move to the left, and the left toggle part 82 toggles the first left wall 35, Make the left interlocking hook 31 rotate, the left guide slide part 33 on the left interlocking hook 31 turns into in the left interlocking hook inflection point groove 12, the first left wall 35 rotates downward, the first left wall 35 is no longer blocking the shifting block, the door can Continue to move to the left, and now the right toggle part 83 will toggle the right linkage hook 61 to rotate, and the follow-up moving process is the same as the process of moving to the right, but in the opposite direction. The best use of this device is on the three-door system. The housing 1 is installed in the middle of the beam, and the movable door is the middle door. A shift block is set on the middle door. In the closed state, move to the right to open to the right, and move to the left to open to the left.
