Detailed Description

The application is described in further detail below with reference to fig. 1-7.

The embodiment of the application discloses a sound-insulation double-opening vertical hinged door. Referring to fig. 1 and 2, a soundproof double-opening vertical hinged door includes a door frame 1 and two door panels 2 installed in the door frame 1, and when in use, the door frame 1 is embedded in a wall. The door plate 2 is provided with a vent 21, the vent 21 penetrates through the door plate 2, the vent 21 is covered with a cover plate 22, and the cover plate 22 is rotatably connected to the upper edge of the vent 21. The upper edge of the vent 21 is provided with a connecting shaft 211, and the connecting shaft 211 penetrates through the cover plate 22, so that the cover plate 22 is rotationally connected with the upper edge of the vent 21 through the connecting shaft 211.

Referring to fig. 2 and 3, the door panel 2 is provided with a control assembly 3, and the control assembly 3 includes a control torsion spring 31, a snap post 32, and a trigger 33. The control torsion spring 31 is coaxially sleeved on the connecting shaft 211, one end of the control torsion spring 31 is connected to the connecting shaft 211, and the other end of the control torsion spring 31 is arranged on one side of the cover plate 22 away from the ventilation opening 21 and is used for pushing the cover plate 22 to be closed. The clamping post 32 is rotatably connected to the door panel 2, and the control torsion spring 31 is disposed at one end of the cover plate 22 facing away from the vent 21 and clamped to the clamping post 32.

Referring to fig. 3 and 4, the trigger 33 includes a push rod 331, a piston 332, and a mounting tube 333. The mounting tube 333 is closed at one end and is filled with a thermally expandable material, such as expanded graphite, and the piston 332 is slidably coupled to the inner wall of the mounting tube 333, so that the material inside the mounting tube 333 can expand when being affected by the ambient temperature, thereby pushing the piston 332 to slide. One end of the push rod 331 is fixedly connected with the piston 332, the other end is hinged with a collar 334, and the collar 334 is sleeved and slidingly connected with the clamping column 32.

In case of fire on one side of the door panel 2, the material inside the installation tube 333 expands at this time, thereby pushing the piston 332 to slide. And under the transmission of the push rod 331, the clamping post 32 can be pushed to rotate, so that the clamping post 32 releases the limit on the control torsion spring 31, the control torsion spring 31 can reset and automatically push the cover plate 22 to close the ventilation opening 21, and the possibility of fire or smoke diffusion is reduced. And the cover plate 22 does not need to be closed manually by surrounding personnel, so that the fireproof performance of the double-opening vertical hinged door is improved. At the same time, the collar 334 can increase the stability of the push rod 331 when acting on the clamping post 32.

In addition, when no fire breaks out around, the mounting tube 333 and the piston 332 are relatively stable, and the push rod 331 is not easily pushed to slide. 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 used normally.

In other embodiments, the trigger 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 is sensed to occur around, the driving motor can be triggered to act, 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 at one side of the cover plate 22 away from the ventilation opening 21. However, in the above-mentioned manner, the elastic force of the control torsion spring 31 is small due to the small rotation amplitude when the movable end of the control torsion spring 31 rotates.

Referring to fig. 5, therefore, in the present embodiment, the connecting shaft 211 is sleeved and rotatably connected with the adjustment sleeve 4, and one end of the control torsion spring 31 connected to the connecting shaft 211 is slidably connected to the adjustment sleeve 4 along the axial direction of the connecting shaft 211. The outer wall of the connecting shaft 211 is provided with an annular clamping groove 212, the clamping groove 212 and the connecting shaft 211 are coaxially arranged, the side wall of the clamping groove 212 is also provided with a plurality of positioning grooves 213, and the positioning grooves 213 are distributed around the axis of the connecting shaft 211. The inner wall of the adjusting sleeve 4 is fixedly connected with a plurality of clamping blocks 41, the clamping blocks 41 are slidably connected in the clamping grooves 212, and the clamping blocks 41 are respectively clamped in the positioning grooves 213 in a one-to-one correspondence manner.

When the movable end of the control torsion spring 31 is clamped to the clamping post 32 and the elastic force of the control torsion spring 31 needs to be increased, the sleeve 4 is only required to be slid to slide the clamping block 41 from the positioning groove 213 and enter the clamping groove 212. The adjusting sleeve 4 is then rotated, and the clamping block 41 can slide in the clamping groove 212, so that the rotation amplitude of the movable end of the control torsion spring 31 is increased, the elastic force of the control torsion spring 31 is increased, the movable end of the control torsion spring 31 can also be kept tightly abutted against the cover plate 22 after the cover plate 22 is closed, the possibility that rebound occurs after the cover plate 22 impacts the edge of the ventilation opening 21 is reduced, and the using effect is improved. Finally, the adjusting sleeve 4 is slipped again, so that the clamping block 41 is clamped in the positioning groove 213 again to clamp the adjusting sleeve 4, so that the torsion spring 31 is controlled to be kept in a compressed state, and the use effect is improved.

Referring to fig. 5, in order to further secure the stability of the fixture block 41 in the positioning groove 213, the connecting shaft 211 is coaxially sleeved with a pushing spring 42, one end of the pushing spring 42 is fixedly connected to the connecting shaft 211, and the other end is abutted to the adjusting sleeve 4. The pushing spring 42 can drive the adjusting sleeve 4 to keep a sliding trend towards the positioning groove 213, so that the clamping block 41 is more stably positioned in the positioning groove 213; and, when the adjustment sleeve 4 is rotated to adjust the elastic force of the control torsion spring 31, the pushing spring 42 is not easy to limit the adjustment sleeve 4, and the pushing spring 42 is not easy to be twisted or damaged due to the traction of the adjustment sleeve 4.

Referring to fig. 6, when the trigger member 33 is actuated and the control torsion spring 31 pushes the cover 22 to close, the edge of the vent 21 is fixedly connected with the fireproof expansion strip 5 to increase the sealing effect at the junction between the edge of the cover 22 and the edge of the vent 21. And, preferably, the temperature of the starting expansion of the material inside the installation tube 333 is lower than the temperature of the starting expansion of the fireproof expansion strip 5, so that after the cover plate 22 is covered, the fireproof expansion strip 5 can expand, and further seal the gap between the cover plate 22 and the edge of the ventilation opening 21, thereby increasing the sealing effect after the cover plate 22 is covered, and further reducing the possibility of smoke drifting.

Referring to fig. 6, the cover plate 22 is formed with grooves 221, and the grooves 221 are provided toward the opening of the fire-protecting 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. The fire-resistant expansion strip 5 can thus clamp the cover plate 22 while sealing the gap between the cover plate 22 and the edge of the vent 21, reducing the likelihood that the closed cover plate 22 will be pushed open by the fire-resistant expansion strip 5.

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-resistant expansion strip 5, the edge of the vent 21 is provided with a plurality of locking pieces 6, and the locking pieces 6 include locking pieces 61 and power springs 62. The locking block 61 is penetrated and glidingly connected to the edge of the ventilation opening 21, and two ends of the power spring 62 are respectively fixedly connected to the locking block 61 and the edge of the ventilation opening 21. 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.

In order to reduce the influence of the lock block 61 on the cover plate 22 when the cover plate 22 is used in a normal state, the locking piece 6 is provided with a locking piece 63, the locking piece 63 is slidingly connected to the edge of the vent 21, and the compressed power spring 62 is locked to the locking piece 63. So that the power spring 62 is not easy to push the locking block 61 to slide during normal use, and the cover plate 22 can be normally opened and closed at this time.

The locking tab 63 is fixedly connected to the pull cord 64, 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. One end of the hauling cable 64 far away from the locking piece 63 bypasses the fireproof expansion strip 5 and is fixedly connected to the edge of the ventilation opening 21. When the fireproof expansion strip 5 expands, the traction rope 64 bound 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 piece 61 can enter the locking hole 222 on the cover plate 22 to further lock the cover plate 22.

The implementation principle of the sound-insulation double-opening vertical hinged door provided by the embodiment of the application is as follows: in case of fire on one side of the door panel 2, the material inside the installation tube 333 expands at this time, thereby pushing the piston 332 to slide. Then, under the transmission of the push rod 331, the clamping post 32 can be pushed to rotate, so that the clamping post 32 releases the limit on the control torsion spring 31, the control torsion spring 31 can reset and automatically push the cover plate 22 to close the ventilation opening 21, and the possibility of fire or smoke diffusion is reduced.

The fireproof expansion strip 5 expands, so that a gap between the cover plate 22 and the edge of the ventilation opening 21 is sealed, the sealing effect of the cover plate 22 after being covered is improved, and the possibility of smoke floating is further reduced. And part of the fireproof expansion strip 5 can enter the groove 221 and is clamped with the groove 221; at the same time, the traction rope 64 bound 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 lock the cover plate 22.

And the surrounding personnel do not need to approach and manually close the cover plate 22, so that the fireproof performance and the safety performance of the double-opening vertical hinged door are improved.
