After the driving member 12 is abutted with the linkage member 8, the abutting member 11 abuts against the limiting post 10 to limit the sliding of the sliding block 6.
The end of the limit post 10 in the first guide rail 4 is inclined from the middle to two sides and forms a first inclined plane and a second inclined plane, so that the limit post 10 is pressed back into the second guide rail 5 when the sliding block 6 moves in the first guide rail 4.
The driving piece 12 comprises a spring 13 arranged between the abutting piece 11 and the limiting column 10, an electromagnetic coil 14 arranged on the positioning block 9, and a control unit 15 for controlling the electromagnetic coil 14 to be powered on or powered off. When the electromagnetic coil 14 is powered on, the electromagnetic coil 14 adsorbs the abutting piece 11 to press the spring 13, and the spring 13 is abutted against the limiting post 10, so that the spring extends into the first guide rail 4, and the inclined surface of the end part of the limiting post 10 abuts against the sliding block 6 to limit the sliding block 6. When the electromagnetic coil 14 is powered off, the spring 13 drives the abutting piece 11 to reset, the limiting column 10 is in a natural state, and the sliding block 6 presses the limiting column 10 back into the second guide rail 5, so that the limiting column 10 loses the limiting effect on the sliding block 6.

The conductive strip 152 may be mounted in various ways, such as on the opposite side wall of the second rail 5 or on one side wall and the bottom plate.
In the process of using the linkage door closer, the opening amplitude of the door can be adjusted by adjusting the position of the limiting assembly 7 in the second guide rail 5. In the prior art, the cable is generally used for conducting electricity to the limiting assembly 7, but if the limiting assembly 7 moves frequently, the cable is often rolled up to wear or break, so that the stability of the linkage door closer is affected. Therefore, the conducting strip 152 fixed on the inner wall of the second guide rail 5 is used for conducting electricity to the limiting assembly 7, so that the danger of damage caused by repeated winding and unwinding of the cable due to frequent movement of the limiting assembly 7 can be avoided, and the linkage door closer can work more stably.
The control unit 15 further includes a fuse 153 connected in series with the first reed pipe 151, and when a fire occurs, the fuse 153 is fused at a high temperature so that the electromagnetic coil 14 is deenergized. The fuse 153 may be mounted outside the link module 1 or in a place where a fire is likely to occur, and is not limited thereto.
The control unit 15 further includes a manual switch 154, where the manual switch 154 is disposed on a circuit formed by the conductive strip 152, the first reed switch 151, and the electromagnetic coil 14, or the manual switch 154 is disposed on a circuit formed by the fuse 153, the conductive strip 152, the first reed switch 151, and the electromagnetic coil 14. When the manual switch 154 and the first reed switch 151 are simultaneously closed, the electromagnetic coil 14 is energized. When it is desired to manually reset the restraint assembly 7, closing the manual switch 154 de-energizes the solenoid 14 to close the fire door.

When the fire door needs to be closed, the manual switch 154 is closed in a manual mode, so that the electromagnetic coil 14 is powered off, after the electromagnetic coil 14 loses magnetic force, the spring 13 drives the abutting piece 11 to reset, the limiting post 10 is in a natural state, the sliding block 6 presses the limiting post 10 back into the second guide rail 5, and therefore the limiting post 10 loses the limiting effect on the sliding block 6, and the sliding block 6 can slide along the second guide rail 5 until the fire door is closed. After the fireproof door is closed, the magnet on the sliding block 6 is opposite to the second reed pipe 161 to close, and the feedback device 16 is electrified to send out a signal that the linkage door closer is in a door closing state.
2. When the fuse 153 is fused along with the gradual rise of the ambient temperature under the dangerous state (in the case of fire), the electromagnetic coil 14 loses magnetic force after losing electricity, the spring 13 drives the interference piece 11 to reset, the limit post 10 is in a natural state, the slide block 6 presses the limit post 10 back into the second guide rail 5, so that the limit post 10 loses the limit function on the slide block 6, and the slide block 6 can slide along the second guide rail 5 until the fireproof door is closed. After the fireproof door is closed, the magnet on the sliding block 6 is opposite to the second reed pipe 161 to close, and the feedback device 16 is electrified to send out a signal that the linkage door closer is in a door closing state.
