Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof doors, in particular to an embedded sound insulation fireproof door. Background Art

[0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. They are fireproof partitions with certain fire resistance, located between fire compartments, evacuation stairwells, vertical shafts, etc. They are specially used to isolate fire sources in housing buildings and play a huge role in firefighting work. Once a fire occurs, people can get a chance to escape through fire doors.

[0003] The utility model with publication number CN219840549U discloses an embedded soundproof fire door, including a frame, a soundproof fire door and a storage bin, the outer wall of the frame is provided with a button, and the storage bin is provided with an opening component for opening the soundproof fire door. In the above application document, the winding roller is driven to reverse by controlling the operation of the motor, and at the same time, the spring pushes the slider to slide to a specified position on the inner wall of the slide groove and the outer wall of the slide rod, thereby driving the soundproof fire door to close and ensuring the fire prevention effect. It is necessary to control the start of the motor to drive the fire door to close. In a fire environment, the control motor may be damaged by high temperature, which may easily cause the fire door to fail to close in time to prevent the spread of fire. Utility Model Content

[0008] Furthermore, in the initial state, one-half of the clamping block is in the clamping slot, the push rod is in the clamping slot, and the clamping block is stuck in the clamping slot so that the soundproof fire door body cannot fall.

[0009] Furthermore, the guide tube is located directly below the pressure rod, and the material of the guide tube is metallic copper. When the thermal expansion airbag expands due to heat, the guide tube will squeeze the pressure rod to drive it to move upward. The guide tube made of metallic copper has good thermal conductivity and can quickly transfer the heat from the surrounding environment to the thermal expansion airbag.

[0010] Furthermore, the buffering noise reduction mechanism includes a slide groove, which is opened inside the door frame, and a buffer spring is provided at the inner bottom of the slide groove. A buffer plate is slidably connected to the inside of the slide groove through the buffer spring, and a contact rod is fixedly connected to the side of the buffer plate, and deceleration particles are fixedly connected to the inner wall of the slide groove.

[0014] 1. The utility model is provided with an automatic closing mechanism, so that through the cooperation of the guide cylinder, the heat expansion airbag, the air pressure chamber and other components, when the surrounding temperature exceeds the standard in the event of a fire, the card block will leave the card slot and retract into the groove. At this time, the soundproof fire door body will fall quickly under the action of gravity and the compression spring to close the passage to prevent the fire.

[0015] 2. The utility model is provided with a buffer noise reduction mechanism, thereby achieving the effect of buffering the falling of the main body of the soundproof fire door through the cooperation of the buffer plate, buffer spring, contact rod and other components, thereby preventing the main body of the soundproof fire door from falling too fast and hitting the bottom of the door frame to cause damage and noise.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

A clamping block 62 is slidably connected to the inside of the groove 61 through the telescopic spring 69. The clamping groove 63 is opened on the inner wall of the door frame 1. The air pressure chamber 64 passes through and is fixedly connected to the side of the door frame 1. A pressure rod 65 is slidably connected to the inner wall piston at one end of the air pressure chamber 64, and a push rod 66 is slidably connected to the inner wall piston at the other end of the air pressure chamber 64. A guide cylinder 67 is fixedly connected to the side of the door frame 1, and a heat expansion airbag 68 is arranged inside the guide cylinder 67.

[0027] The size of the soundproof fire door body 4 is larger than the passage 2. The compression spring 3 is in a taut state in the initial state. The soundproof fire door body 4 moves downward to completely close the passage 2. When the compression spring 3 rebounds, it can drive the soundproof fire door body 4 to fall quickly.

[0028] In the initial state, one half of the block 62 is in the slot 63, and the push rod 66 is in the slot 63. The block 62 is stuck in the slot 63 so that the soundproof and fireproof door body 4 cannot fall.

[0029] The guide tube 67 is located directly below the pressure rod 65, and the material of the guide tube 67 is metallic copper. When the thermal expansion airbag 68 expands due to heat, the guide tube 67 will squeeze the pressure rod 65 and drive it to move upward. The guide tube 67 made of metallic copper has good thermal conductivity and can quickly transfer the heat of the surrounding environment to the thermal expansion airbag 68.

[0030] The buffering noise reduction mechanism 7 includes a slide groove 71, which is opened inside the door frame 1. A buffer spring 72 is provided at the inner bottom of the slide groove 71. A buffer plate 73 is slidably connected to the inside of the slide groove 71 through the buffer spring 72. A contact rod 74 is fixedly connected to the side of the buffer plate 73. The inner wall of the slide groove 71 is fixedly connected to deceleration particles 75.

[0031] The slide groove 71 is located directly below the insertion block 5 , and the opening size of the slide groove 71 is larger than the insertion block 5 . When the soundproof fire door body 4 falls, the insertion block 5 will enter the slide groove 71 and contact the buffer plate 73 .

[0032] The length of the contact rod 74 is greater than the distance from the side of the buffer plate 73 to the deceleration particles 75. The buffer plate 73 and the deceleration particles 75 are both made of rubber. When the contact rod 74 moves downward, it will contact the deceleration particles 75. The rubber buffer plate 73 has a certain elasticity and can play a buffering role. When the contact rod 74 and the rubber deceleration particles 75 are squeezed, a certain resistance will be generated.

[0033] A specific application of this embodiment is as follows: at the beginning, the passage 2 is in an open state, and people and air can pass through normally. When a fire occurs, the ambient temperature continues to rise, and the heat expansion airbag 68 begins to expand due to the heat. When the heat expansion airbag 68 expands due to the heat, the guide tube 67 squeezes the pressure rod 65 to drive it to move upward. The pressure rod 65 moves upward and drives the push rod 66 to move outward through the air pressure in the air pressure chamber 64. The push rod 66 moves outward and squeezes the block 62 to make it leave the card slot 63 and retract into the groove 61. The telescopic spring 69 is tightened. At this time, the soundproof fire door body 4 will fall quickly under the action of gravity and the compression spring 3 to close the passage 2 to prevent the fire. When the soundproof fire door body 4 is lifted, the groove 61 and the card slot 6 When the soundproof and fireproof door body 4 overlaps, the rebound of the telescopic spring 69 will drive the card block 62 to re-enter the card slot 63 so that the soundproof and fireproof door body 4 is fixed, and when the soundproof and fireproof door body 4 falls, the insertion block 5 will enter the slide slot 71 and contact the buffer plate 73. The buffer plate 73 made of rubber has a certain elasticity and can play a buffering role. The buffer plate 73 moves downward so that the buffer spring 72 absorbs the impact force and gradually tightens. In the process of the buffer plate 73 moving downward, the contact rod 74 will also be driven to move downward and release the deceleration particles 75. At this time, the contact rod 74 will be squeezed with the deceleration particles 75 to generate a certain resistance to further improve the buffering effect, thereby preventing the soundproof and fireproof door body 4 from falling too fast and hitting the bottom of the door frame 1 to cause damage and noise.
