specific Embodiment I

[0056] Specific embodiment I: the first connecting piece 303 is L-shaped; the end of one side of the first connecting piece 303 is connected to the first connecting shaft 301 through a long hole 303A; the first connecting piece 303 The other side of the second connecting shaft 302 is connected through a through hole; the junction of the two sides of the first connecting piece 303 is connected with the third connecting shaft 305; axial movement occurs in the gear shaft 203 , the first connecting piece 303 rotates along the third connecting shaft 305, and on the premise that the third connecting shaft 305 is fixed, it generates a pulling force on the second slider 104, driving the second slider 104 to move in the second chute 103, The latch body 103 is directly pulled out from the fixing portion 106 .

[0057] Preferably, in order to prevent interference, the first connecting piece 303 is arranged parallel to the second connecting piece 304; the second connecting shaft 302 is co...

Abstract

In order to solve the problem that in the prior art, rapid opening cannot be achieved, an emergency lock assembly and a shielding door are provided. The emergency lock assembly comprises a plunger latch mechanism, a lifting mechanism and an emergency unlocking mechanism. The lifting mechanism is connected with the plunger latch mechanism and used for lifting the plunger latch mechanism so as to lock the plunger latch mechanism; and the emergency unlocking mechanism is connected with the lifting mechanism and used for changing the plunger latch mechanism from a locked state to an unlocked statethrough axial movement of the lifting mechanism in an emergency state. The lifting mechanism is connected with the plunger latch mechanism, and the plunger latch mechanism is lifted, so that lockingis completed; the emergency unlocking mechanism is connected with the lifting mechanism, and in an emergency state, the plunger latch mechanism is changed into an unlocking state from a locking statethrough axial movement of the lifting mechanism. The structure is simple, mechanical action is adopted, reliability is high, and the safety index of a shielding chamber can be greatly improved.

Description

technical field [0001] The invention relates to the field of screen doors, in particular to an emergency lock assembly and a screen door. Background technique [0002] The shielding door is a shielding device specially set up for shielding electromagnetic waves in some important occasions. Existing screen doors are driven by motors to be closed and opened, which is relatively convenient. [0003] However, after the screen door is closed, if it needs to open the door quickly in emergency situations such as a fire, it will be in a shutdown state due to the lack of power supply due to the fire, such as the motor. Generally, when the screen door is locked, it is necessary for the bolt to cooperate with the fixed plate, such as figure 1 , lock the door. [0004] Therefore, when accidents such as fire occur, the handle needs to be turned manually to remove the bolt from the fixing plate, thereby opening the door. This just causes the opening speed to be very slow, has increase...
