The working principle of the invention is as follows:
referring to fig. 1-3, in the initial state, the door panel 12 is in the closed state, the gear 19 is not engaged with the racks 20 on both sides thereof (the engaged and disengaged edges, i.e., the toothed side of the gear 19, are engaged, the teeth of the gear 19 on the left side are directed to the right, the teeth on the gear 19 on the right side are directed to the left in the view of fig. 3), and when the door panel 12 is opened (toward either side), the door panel 12 rotates about the rotation shaft 23, and at the same time, the door panel 12, the rotation shaft 23 and the slider 22 slide along the chute 21; specifically, when the door panel 12 is subjected to an external force, the door panel 12 rotates around the rotation shaft 23, and drives the rotation shaft 23 to rotate together, the gear 19 rotates together with the rotation shaft 23, at this time, the gear 19 is meshed with the rack 20 on one side of the gear 19, no matter which side of the door panel 12 is opened, the gear 19 can move along the rack 20 toward the middle of the door frame 11, and when the door panel 12 is closed from an opened state, the gear 19 reversely rotates, so that the principle is the same.
When the door plate 12 is changed from a closed state to an open state, the sliding block 22 slides along the sliding groove 21, the connecting plate 17 moves along with the sliding block 22, the piston rod of the hydraulic rod 16 and the connecting plate 17 are synchronously pulled out, the oil pressure in the hydraulic rod 16 changes, after the force for opening the door plate 12 is removed, the potential energy accumulated by the hydraulic rod 16 enables the connecting plate 17 to reset, the sliding block 22 is driven to move reversely, the sliding block 22 moves to drive the rotating shaft 23 to rotate, and then the door plate 12 is driven to rotate, so that the door plate 12 can be closed independently and is in a normally closed state; the hydraulic rod 16 of the part refers to the principle of the existing hydraulic door closer, the hydraulic device is similar to a spring, the connecting rod pushes the gear to drive the rack plunger to move, hydraulic oil in the rack plunger is compressed, the potential energy is accumulated by the reset spring, after the door opening process is finished, the spring is compressed in the opening process, the accumulated elastic potential energy is released, the plunger is pushed to the left side, and the transmission gear and the door closer connecting rod are driven to rotate, so that the door is closed; the piston rod of the hydraulic rod 16 is equivalent to a rack plunger, and a return spring, a throttle valve and the like are also arranged in the cylinder barrel of the hydraulic rod 16 and used for buffering the door closing action and enabling the door closing speed to be adjustable; in the spring release process, the hydraulic oil in the left cavity of the door closer is compressed, the one-way valve is closed, and the hydraulic oil can only flow out through a gap between the shell and the plunger and flows back to the right cavity through the small hole in the plunger and the two flow passages provided with the throttle valve cores. Therefore, the hydraulic oil forms resistance to the release of the spring, namely, the buffer effect is achieved through throttling, so that the closing speed of the door is controlled. The throttle valve on the valve body can be adjusted to control the variable closing speed of different stroke sections.
When the door plate 12 is closed, the piston rod of the hydraulic rod 16 has a tendency to shrink into the cylinder, no external force is applied or the applied force is too small (natural factors, wind blowing and the like) to overcome the tensile force of the hydraulic rod 16, and the door plate 12 cannot easily rotate; the door panel 12 will remain in equilibrium with the fire door normally closed.
When the door panel 12 is closed or opened, the sequence of opening or closing the door panel 12 is certain due to the existence of the shielding strip 24, referring to fig. 4, when the door panel 12 is closed in this state, the door panel 12 on the right side needs to be closed first and then the door panel 12 on the left side is closed, and when the door panel 12 is opened towards the other side, the closing sequence is opposite;
in an initial state (a closed state of the door panel 12), the sequencer 13 is horizontally accommodated in the control space 29, the right-angle sleeve 25 is horizontally in a state, and coil springs in the limiting plates 27 have a continuous trend, so that the control belt 28 is kept taut;
referring to fig. 3, when the door panel 12 is changed from the closed state to this state, the control belt 28 is loosened by the movement of the slide block 22, the coil spring is immediately wound up, the slide sleeve 31 rotates counterclockwise, the slide sleeve 31 drives the sequencer 13 to rotate, the right-angle sleeve 25 moves along with the sequencer 13, after the right-angle sleeve 25 extends out of the control space 29, the right-angle sleeve sags under the action of gravity (the joint adopts a ball bearing and can be easily rotated), the horizontal is changed into vertical, ninety degrees of rotation is not allowed to continue to rotate, and at the moment, the sagged part of the right-angle sleeve 25 coincides with the upper edge of the door panel 12 in the vertical direction, namely the right-angle sleeve 25 can block the closing of the door panel 12;
referring to fig. 7 to 8, when the control shaft 26 is rotated by the influence of the coil spring, the screw thread 34 moves the control shaft 26 downward with respect to the door frame 11, the rotation sleeve 30 and the control shaft 26 slide, the horizontal height of the rotation sleeve 30 is unchanged, and the bottom of the rotation sleeve 30 always contacts the limiting plate 27; the control shaft 26 and the sliding sleeve 31 also slide, and the spring in the control spring 32 is compressed to accumulate potential energy; when the sequencer 13 rotates to a position overlapping with the notch 35 (the sequencer 13 cannot continue to rotate in this state, but can move, and can continue to rotate after moving), the sequencer 13 can spring out under the action of the control spring 32, and the control spring 32 releases the pressure; at this time, the sequencer 13 is located at the lower side of the top door frame 11, the door plate 12 is continuously opened, the control belt 28 continuously has a loosening trend, and the coil spring continuously tightens the control belt, so that the sequencer 13 continuously rotates;
still referring to FIG. 3, when the door panel 12 is closed from this condition, movement of the slider 22 pulls the control strap 28, forcing the coil spring to stretch; specifically, referring to fig. 7-8, in this process, the control shaft 26 is driven by the rotating sleeve 30 to rotate, the sliding sleeve 31 is driven by the control shaft 26 to rotate, the sliding sleeve 31 and the limiting plate 27 rotate, the coil spring is stretched, meanwhile, the control shaft 26 moves upwards under the action of the screw thread 34, the control shaft 26 and the sliding sleeve 31 slide, the control spring 32 stretches, potential energy is accumulated, when the sequencer 13 moves to a position overlapping with the notch 35, the control spring 32 releases energy to enable the sequencer 13 to move upwards, the sequencer 13 returns to a state of being flush with the reserved groove 15, the door plate 12 continues to be closed, the control belt 28 is pulled by the sliding block 22, and the sequencer 13 continues to rotate by the control belt 28 until the sequencer 13 is accommodated in the control space 29; when the right-angle sleeve 25 touches the door frame 11, the right-angle sleeve 25 rotates from a vertical state to a horizontal state;
in the above process, when the door panel 12 is closed from the opened state shown in fig. 3, the left door panel 12 will touch the right-angle sleeve 25, so that the left door panel 12 cannot rotate continuously, the right door panel 12 can rotate continuously, when the left door panel 12 does not rotate the right door panel 12, the left control belt 28 is loosened, the right control belt 28 is tightened all the time, the right door panel 12 will be closed first without interference, and the left door panel 12 will be closed after the sequencer 13 is accommodated in the control space 29, so that the closing doors are in sequence, and the shielding strips 24 can be overlapped smoothly; when the sequencer 13 returns to the flush position of the pre-groove 15 and the right-angle sleeve 25 does not contact the door frame 11, the right-angle sleeve 25 moves upwards, but still has a superposition part with the door panel 12 in the vertical direction, and still limits the closing of the door panel 12.
In the present invention, the other parts except the door panel 12 are rotationally symmetrical with the control shaft 26 as the symmetry center, so the principles of the left and right sides are the same, and the principles of the door panel 12 are the same when the door panel 12 is opened forward and backward, i.e. the two rotation shafts 23 are rotated forward and backward, so the same principles are not repeated.
