The clamping column 32 is rotatably connected to the door panel 2, and the control torsion spring 31 is arranged at one end of the cover plate 22, which is far away from the ventilation opening 21, and clamped on the clamping column 32.

Referring to fig. 3 and 4, the trigger 33 includes a push rod 331, a piston 332, and a mounting tube 333. One end of the installation pipe 333 is closed, the interior of the installation pipe 333 is filled with a thermal expansion material, such as expanded graphite, and the piston 332 is connected to the inner wall of the installation pipe 333 in a sliding manner, so that the material inside the installation pipe 333 can expand when being influenced by the ambient temperature, and the piston 332 is pushed to slide. One end of the push rod 331 is fixedly connected to the piston 332, and the other end is hinged to a lantern ring 334, and the lantern ring 334 is sleeved and slidably connected to the clamping column 32.

If a fire breaks out on one side of the door panel 2, the material inside the mounting tube 333 expands at this time, and the piston 332 is pushed to slide. And under the transmission of push rod 331, can promote the rotation of joint post 32 to make joint post 32 remove the restriction to control torsional spring 31, make control torsional spring 31 can take place to reset and automatic promotion apron 22 close vent 21, in order to reduce the possibility that the intensity of a fire or smog spread. And people around do not need to walk near and manually close the cover plate 22, and the fire resistance of the double-opening vertical hinged door is improved. Simultaneously, the stability when push rod 331 acts on joint post 32 can be increased to the lantern ring 334 that sets up.

In addition, when a fire is not generated around, the mounting tube 333 and the piston 332 are relatively stable, and the push rod 331 is not easily pushed to slide at this time. Therefore, the clamping column 32 can be in a normal state, the control torsion spring 31 is clamped, and the cover plate 22 is not easily influenced by the control torsion spring 31 and can be normally used.

In other embodiments, the triggering member 33 may also be configured as a driving motor, and the driving motor is provided with a temperature sensor or a smoke sensor, so that when a fire around the driving motor is sensed, the driving motor can be triggered to operate, and the cover plate 22 is controlled to rotate.

In use, in order to make the control torsion spring 31 have an elastic force for pushing the cover plate 22 to close, the movable end of the control torsion spring 31 is usually rotated and finally disposed on the side of the cover plate 22 away from the vent 21. However, when the above-mentioned method is adopted, the elastic force of the control torsion spring 31 is small due to the small rotation range when the movable end of the control torsion spring 31 rotates.

Referring to fig. 5, in this embodiment, the connecting shaft 211 is sleeved and rotatably connected with the adjusting sleeve 4, and the control torsion spring 31 is connected to one end of the connecting shaft 211 and slidably connected to the adjusting sleeve 4 along the axial direction of the connecting shaft 211. Annular draw-in groove 212 has been seted up to connecting axle 211 outer wall, and draw-in groove 212 and the coaxial setting of connecting axle 211, and a plurality of constant head tank 213 have still been seted up to draw-in groove 212 lateral wall, and a plurality of constant head tanks 213 encircle the axis distribution of connecting axle 211. The inner wall of the adjusting sleeve 4 is fixedly connected with a plurality of blocks 41, the blocks 41 are slidably connected in the slots 212, and the blocks 41 are respectively and correspondingly clamped in the positioning slots 213.

Moreover, preferably, the temperature at which the material inside the mounting tube 333 begins to expand is lower than the temperature at which the fireproof expansion strip 5 begins to expand, so that after the cover plate 22 is covered, the fireproof expansion strip 5 can expand, and further, a gap between the cover plate 22 and the edge of the vent 21 is sealed, so that the sealing effect after the cover plate 22 is covered is increased, and the possibility of smoke flowing out is further reduced.

Referring to fig. 6, the cover plate 22 is formed with a groove 221, and the groove 221 is disposed to open toward the fire-proof expansion strip 5. After the fireproof expansion strip 5 expands, part of the fireproof expansion strip 5 can enter the groove 221 and be clamped with the groove 221. Therefore, the fireproof expansion strip 5 can seal the gap between the cover plate 22 and the edge of the vent 21, and simultaneously can clamp the cover plate 22, so that the possibility that the closed cover plate 22 is pushed away by the fireproof expansion strip 5 is reduced.

Referring to fig. 6 and 7, at the same time, in order to further reduce the possibility that the cover plate 22 is pushed away by the fire-proof expansion strip 5, the edge of the ventilation opening 21 is provided with a plurality of clamping pieces 6, and the clamping pieces 6 comprise locking blocks 61 and power springs 62. The locking block 61 is inserted and slidably connected to the edge of the vent 21, and two ends of the power spring 62 are fixedly connected to the locking block 61 and the edge of the vent 21 respectively. The cover plate 22 is provided with a locking hole 222 matched with the locking block 61, so that after the cover plate 22 is covered, the power spring 62 can push the locking block 61 to slide, and the locking block 61 can penetrate through the locking hole 222, so that the cover plate 22 is locked.

Moreover, when the cover plate 22 is used in a normal state, in order to reduce the influence of the locking block 61 on the cover plate 22, the locking piece 6 is provided with a locking piece 63, the locking piece 63 is connected to the edge of the ventilation opening 21 in a sliding manner, and the compressed power spring 62 is clamped to the locking piece 63. Therefore, in normal use, the power spring 62 is not easy to push the locking block 61 to slide, and the cover plate 22 can be normally opened and closed.

The locking tab 63 has a pull cord 64 fixedly attached thereto, although the pull cord 64 may be made of metal in order to reduce the likelihood of failure of the pull cord 64 due to heat. The end of the pulling rope 64 far away from the locking piece 63 is wound around the fireproof expansion strip 5 and then fixedly connected to the edge of the ventilation opening 21. When the fireproof expansion strip 5 expands, the pulling rope 64 tied on the fireproof expansion strip 5 is pushed to expand, and the locking piece 63 is pulled to slide, so that the restriction of the power spring 62 is released, and the locking block 61 can enter the locking hole 222 on the cover plate 22 to further lock the cover plate 22.

The implementation principle of this application embodiment a two vertical hinged doors that open give sound insulation does: if a fire breaks out on one side of the door panel 2, the material inside the mounting tube 333 expands at this time, and the piston 332 is pushed to slide.
