Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example one
Referring to fig. 1 and 2, the utility model discloses a fire door is prevented to two divisions that sealing performance is good, it includes door frame 1, door leaf A2 and door leaf B3. The top of door frame 1 has set firmly roof 11, has seted up a complete guide way 4 on door frame 1 and the roof 11, and it has baffle 5 to articulate on the door leaf A, and the rigid coupling has slide bar 6 on the baffle 5, and the last swivelling joint of slide bar 6 has pulley 61, and pulley 61 is sliding connection with guide way 4 and sets up.
Referring to fig. 3, the sliding rod is shaped like L, one end of which is fixed at the center of the baffle 5, and the other end of which is rotatably connected with the pulley 61.
Referring to fig. 3 and 4, the guide groove 4 includes a transverse groove 41 and a longitudinal groove 42, the transverse groove 41 is formed on the top plate 11, the longitudinal groove 42 is formed on the door frame 1, one end of the longitudinal groove 42 is connected to the transverse groove 42, and the other end is an opening through which the pulley 61 can enter, and when the door is closed, the pulley 61 can slide into the guide groove 4 from the opening of the longitudinal groove 42.
Referring to fig. 3 and 4, the blocking plate 5 is a curved plate having a circular arc shape and has the same length as the height of the door leaf a. The top and the bottom of baffle 5 all the rigid coupling have arc 51, and when taking place conflagration, arc 51 can effectually block the smog that gets into in the baffle 5. One side of the baffle 5 is hinged on the door leaf A2 of the double-open fireproof door through a hinge, and the other side is sleeved with the fireproof strip 52.
The implementation principle of the above embodiment is as follows: when the double-open fireproof door is closed, the fireproof strip 52 and the arc-shaped plate 51 of the baffle 5 abut against the door leaf B3, and the pulley 61 is positioned in the transverse groove 41; when the double-opening fireproof door is opened, the pulley 61 slides from the transverse groove 41 to the longitudinal groove 42, the baffle 5 starts to open towards the hinged end of the door leaf A2 along with the sliding of the pulley 61, and when the pulley 61 completely slides out of the longitudinal groove 42, the baffle 5 can be opened and closed to a certain angle, so that the closing of the door leaf B3 is just not blocked. Even if the door B3 is closed first when the door a2 is closed and the shutter 5 is in the open state at this time and does not interfere with the door B3 when the door is ready to be closed, the slide bar 6 enters the guide groove during the closing of the door a2, so that the shutter 5 starts to turn over in the direction of the door B3, and the shutter 5 abuts against the door B3 when the door a2 is completely closed. The arc-shaped plate 51 and the fire-proof strip 52 of the baffle 5 are tightly attached to the door leaf B3, and the double-opening fire-proof door has the fire-proof function.
Example two
The difference from the first embodiment is that a spring 7 is connected between the barrier 5 and the door leaf a 2.
Referring to fig. 5 and 6, one end of the spring 7 is fixed inside the barrier 5, and the other end is fixed to the door leaf a 2. When the spring 7 returns to its original length, the support flap 5 is opened, and when the fire door is closed, even if the door B3 is closed first, the flap 5 does not obstruct the closing of the door B3, and when the door a2 is closed, the pulley 61 can just enter the guide groove 4 from the opening of the guide groove 4.
The implementation principle of the above embodiment is as follows: when the double-open fireproof door is closed, the fireproof strip 52 and the arc-shaped plate 51 of the baffle 5 abut against the door leaf B3, the spring 7 is in a compressed state, and the pulley 61 is positioned in the transverse groove 41; when the double-opening fireproof door is opened, the pulley 61 slides from the transverse groove 41 to the longitudinal groove 42, the spring 7 also starts to restore the original length, the baffle 5 is supported to be opened towards the hinged end of the door leaf A2, and when the pulley 61 completely slides out of the longitudinal groove 42, the spring 7 restores the original length, so that the baffle 5 is opened and closed to an angle which just does not block the closing of the door leaf B3. In preparation for closing the door, even if the door B3 is closed first, the flap 5 is more easily held in one position by the spring 7, and the pulley 61 can more accurately enter the opening when the door a2 is closed, so that the flap 5 starts to turn in the direction of the door B3. When the door A2 is completely closed, the baffle 5 abuts against the door B3, the arc-shaped plate 51 and the fireproof strip 52 of the baffle 5 are tightly attached to the door B3, and the fireproof function of the double-opening fireproof door is achieved.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
