Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of fire doors, and in particular to a smoke proof device and a smoke proof door. Background Art
[0002] Fire is a common accident in life. Any place that is in use has the potential for fire. This is because electricity is needed in the place and wires need to be laid. Improper handling of the conductive process of the wires can cause a fire. If there are flammable and explosive items in the place, it will greatly increase the speed of the fire and its spread.
[0003] During a fire, most people die from suffocation due to the thick smoke, while a few are burned to death. Therefore, blocking the thick smoke often provides a greater chance of escape. Currently, the most common fire prevention measure is to install fire doors to prevent the spread of fire. Once installed, a gap exists between the door and the frame, allowing the door to open and close properly. Smoke enters through this gap, causing smoke inhalation and suffocation. Consequently, fire doors cannot effectively block the spread of smoke, nor can they buy time for trapped people to be rescued. Summary of the Invention
[0004] In view of the deficiencies in the prior art, the present invention provides a smoke prevention device and a smoke prevention door.
[0005] The present invention discloses a smoke prevention device, comprising: a support assembly, a pressure supply assembly and a blocking assembly, wherein the blocking assembly comprises a blocking bearing and a blocking member, the pressure supply assembly is arranged on the support assembly, the blocking bearing is connected to the pressure supply assembly, and the blocking member is arranged on the blocking bearing;

[0035] Example 1
[0036] like Figure 1-Figure 2 As shown, Figure 1 A perspective view of a smoke prevention device; Figure 2 This is another schematic diagram of a smoke prevention device. The smoke prevention device of the present application includes a support assembly 1, a pressure supply assembly 2, and a blocking assembly 3. The support assembly 1 is used to carry the pressure supply assembly 2 and the blocking assembly 3. The pressure supply assembly 2 is mounted on the support assembly 1 and is used to provide power. The blocking assembly 3 is movably mounted on the support assembly 1 and is connected to the pressure supply assembly 2. The power provided by the pressure supply assembly 2 drives the blocking assembly 3 to move relative to the support assembly 1, ultimately causing the blocking assembly 3 to move outside the support assembly 1.
[0037] Refer to it again Figure 2 and Figure 3 , Figure 3 The figure is a three-dimensional schematic diagram of the support bar 12. The support assembly 1 includes two support plates 11 and multiple support bars 12. The two support plates 11 are spaced apart from each other, and the multiple support bars 12 are arranged between the two support plates 11 and connected to the two support plates 11. At the same time, the multiple support bars 12 are distributed along the edges of the support plates 11. The support plates 11 and support bars 12 are combined to form a accommodating cavity 13 of the support assembly 1, and the pressure supply assembly 2 is located in the accommodating cavity 13. The support bar 12 has a storage groove 121. When not in use, the blocking assembly 3 is stored in the storage groove 121, so that the overall appearance of the smoke prevention device has no protruding parts and does not affect normal use.
[0038] Refer to it again Figure 2 and Figure 4 , Figure 4This is a partial schematic diagram of the pressure supply assembly 2; the pressure supply assembly 2 includes a pressure storage component 21 and a pressure transmission component 22, both of which are located within the accommodating chamber 13. One end of the pressure transmission component 22 is connected to the pressure storage component 21, and the other end is connected to the blocking assembly 3. The pressure storage component 21 has a pressure storage chamber 211, and the pressure transmission component 22 has a pressure transmission channel 221, and the pressure storage chamber 211 is connected to the pressure transmission channel 221. In specific applications, liquid is introduced into the accommodating chamber 13 within the pressure storage component 21 through a water pipe, and the liquid then flows from the accommodating chamber 13 into the pressure transmission channel 221. When the accommodating chamber 13 is filled with liquid, the pressure generated by the liquid will serve as a driving force and push the blocking assembly 3 to move. Specifically, in order to achieve a better sealing effect, there are four sealing components 3, which are respectively located on the four sides of the support component 1. At the same time, the pressure supply component 2 is also provided with multiple pressure delivery components 22, and the multiple pressure delivery components 22 are respectively connected to the four sealing components 3. The liquid in the pressure storage chamber 211 is continuously rushed in, and the liquid will also continuously flow into the pressure delivery channel 221 corresponding to the water level. After the pressure storage chamber 211 and each pressure delivery channel 221 are filled with liquid, a thrust will be generated on the corresponding sealing component 3 to drive the sealing component 3 to move.
[0039] In another embodiment, the smoke prevention device further includes an interface assembly 4, which connects the blocking assembly 3 and the pressure input member 22. The interface assembly 4 is disposed on the support plate 11, and the blocking assembly 3 is movable relative to the interface assembly 4. Specifically, the interface assembly 4 is a hollow structure, with one end of the pressure input member 22 located within the interface assembly 4, and the end of the blocking assembly 3 connected thereto also located within the interface assembly 4.
[0040] Refer to it again Figure 5-Figure 7 , Figure 5 is a perspective view of the blocking carrier 31; Figure 6 is a side view of the blocking carrier 31; Figure 7 for Figure 4Enlarged view of point A in the middle. The blocking assembly 3 includes a blocking carrier 31 and a blocking member 32. The blocking carrier 31 is movably disposed in the receiving groove 121, and the blocking member 32 is disposed on the side of the blocking carrier 31 away from the support bar 12. The blocking carrier 31 includes a blocking carrier bar 311, a blocking connection block 312, and a blocking connection rod 313. The blocking carrier bar 311 is movably disposed in the receiving groove 121, and the blocking member 32 is disposed on the blocking carrier bar 311. The blocking connection block 312 is disposed on the side of the blocking carrier bar 311 away from the blocking member 32, and the blocking connection block 312 is located in the accommodating cavity 13. One end of the blocking connection rod 313 is connected to the blocking connection block 312, and the other end of the blocking connection rod 313 is movably disposed in the interface assembly 4. The liquid power output by the pressure input channel 221 will drive the blocking connection rod 313 to move relative to the interface assembly 4. The blocking support bar 311 has a first groove 3111, and the blocking member 32 is provided with a fixing portion 33 that fits in the first groove 3111. When the fixing portion 33 is engaged with the first groove 3111, the blocking support bar 311 and the blocking member 32 are fixedly connected. Furthermore, the blocking support bar 311 also has a supporting surface 3112, which mates with the blocking member 32, creating a larger contact area and facilitating force transmission from the blocking support bar 311 to the blocking member 32. Furthermore, the connection between the blocking connecting rod 313 and the blocking connecting block 312 has a flat surface 3131, which mates with the blocking connecting block 312, facilitating connection and fixation between the two.
[0041] Please review Figure 2 , further explained, since the blocking support bar 311 is long, in order to make its movement stable, a plurality of blocking connecting blocks 312 and blocking connecting rods 313 are provided, and are distributed at intervals on one side of the blocking support bar 311. Correspondingly, the number of pressure input parts 22 and interface components 4 is also multiple, and one blocking connecting rod 313 corresponds to one interface component 4, and one interface component 4 corresponds to one pressure input part 22.
[0042] Refer to it again Figures 8-10 , Figure 8 is a three-dimensional diagram of the blocking member 32; Figure 9 is a side view of the blocking member 32; Figure 10This is another three-dimensional diagram of the blocking member 32. The blocking member 32 includes a fixing strip 321 and a blocking strip 322. The fixing strip 321 is adapted to the first groove 3111, and the fixing strip 321 is clamped in the first groove 3111. At this time, the fixing strip 321 will serve as the fixing portion 33 of the blocking assembly 3. The blocking strip 322 is connected to the fixing strip 321, and the local shape of the blocking strip 322 is adapted to the shape of the supporting surface 3112, so that the supporting surface 3112 fits the blocking strip 322. Furthermore, the blocking strip 322 has a deformation hole 3221. When the blocking strip 322 extends out of the support strip 12 and the blocking strip 322 abuts against the outside and is squeezed by pressure, the blocking strip 322 will deform radially. The setting of the deformation hole 3221 improves its deformation effect and space. Furthermore, the side of the blocking strip 322 away from the blocking support strip 311 also has a sealing block 3222. The sealing block 3222 protrudes from the blocking strip 322, and the provision of the sealing block 3222 improves the sealing performance during use. When used on a door, due to the overlapping area of the two door edges at the door corner, to facilitate assembly and improve the sealing effect, the blocking piece 32 is made into two shapes. The first shape is as described above, and the second shape is the structure of the original blocking piece 32 extended at both ends. In specific applications, any two door edges use the first shape of the blocking piece 32, and the other two door panels use the second shape of the blocking piece 32.
[0043] Example 2
[0044] The smoke-proof door of the present application includes a smoke-proof device and a door frame, wherein the smoke-proof device is hinged to the door frame. The smoke-proof device has the same structure as that of the first embodiment, and the detailed structure can be found above, which will not be described here.
[0045] After a fire occurs, the escapees can enter the designated room (bathroom), turn on the faucet to release water, and the water will enter the pressure storage chamber 211 along the water inlet pipe extending from the pressure storage component 21, and then flow from the pressure storage chamber 211 into the pressure delivery channel 221. As the water is continuously replenished, the pressure storage chamber 211 and the pressure delivery channel 221 are filled with water, and then the force generated by the water will act on the blocking connecting rod 313. After the blocking connecting rod 313 is subjected to force, it pushes the blocking connecting block 312 and the blocking bearing bar 311 to move outward. Of course, the blocking bar 322 also moves with the blocking bearing bar 311 until the blocking bar 322 abuts against the door frame, filling the gap between the smoke prevention device and the door frame, and the thick smoke will not be able to spread into the room.
[0046] To sum up, through the coordinated use of the support component 1, the pressure supply component 2 and the blocking component 3, the pressure supply component 2 provides power to the blocking carrier 31, so that the blocking carrier 31 can move relative to the support component 1. At the same time, the blocking carrier 31 also drives the blocking component 32 to move together. Finally, the blocking component 32 moves to the outside of the support component 1, occupying the surrounding space of the support component 1. When used on the door, the blocking component 32 and the door frame abut against each other to form a seal, so as to prevent the entry of thick smoke during a fire and gain more rescue time for the trapped people.
[0047] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
