[0028] The sealing assembly 4 includes an annular mounting block 401. A soft sealing body 402 and a hard sealing body 403 are fixedly mounted on the outer wall of the annular mounting block 401. A cylinder 404 is fixedly mounted on the inner wall of the annular mounting block 401. A cylinder 405 is fixedly mounted on the outer wall of the cylinder 404. A groove 406 is provided on the outer wall of the cylinder 404. A handle 407 is provided on the outer wall of the handle 407. One end of a steel wire rope 408 is fixedly connected to the outer wall of the handle 407. A sliding plate 409 is fixedly connected to the other end of the steel wire rope 408. A cylinder 410 is provided on the inner wall of the cylinder 405. A take-up wheel 411 is rotatably connected to the inner wall of the cylinder 405. One end of a steel wire rope 412 is fixedly connected to the outer wall of the sliding plate 409. A fixing post 414 is fixedly connected to the other end of the steel wire rope 412. A spring 413 is provided in the inner cavity of the cylinder 410.
[0029] In the above structure, by setting the soft sealing body 402 and the hard sealing body 403, the gap between the baffle door body 3 and the door panel body 1 can be sealed by installing the soft sealing body 402 and the hard sealing body 403.
[0030] In a preferred embodiment: the smoke leak warning component 7 includes an alarm body 701, the inner wall of the alarm body 701 is provided with a circular groove 702, the inner wall of the circular groove 702 is provided with an electrode plate 703 and a diaphragm 704 respectively, the outer wall of the alarm body 701 is fixedly mounted with a circular plate 705, the bottom of the circular plate 705 is fixedly connected to one end of a glass tube 706, the other end of the glass tube 706 is fixedly connected to a sliding plate 709, the outer wall of the circular plate 705 is provided with a sliding groove 708, the bottom of the circular plate 705 is fixedly installed with an air pipe 707, the inner wall of the air pipe 707 is provided with a valve 710, and the bottom of the sliding plate 709 is provided with a spring 711.
[0031] In a preferred embodiment: the outer shape of the air tube 707 is wavy, and the air tube 707 is made of soft PVC. There are two glass tubes 706, and the inner cavities of the two glass tubes 706 are respectively filled with liquid. The outer wall shape of the second sliding plate 709 is the same as the inner wall shape of the second sliding groove 708, and the outer wall of the second sliding plate 709 and the inner wall of the second sliding groove 708 are slidably fitted together. The electrode plate 703 is electrically connected to the alarm body 701.
[0032] In the above structure, the arrangement of the air tube 707, electrode plate 703, and diaphragm 704 allows the liquid inside the two glass tubes 706 to boil and evaporate when the gas reaches abnormally high temperatures. This causes the two glass tubes 706 to burst under the pressure of the evaporating gas. Then, the slide plate 709, compressed and rebounded by the spring 711, slides along the slide groove 708, which compresses the air tube 707 made of soft PVC. During compression, the gas inside the wavy-shaped air tube 707 is pushed to the top of the air tube 707 through the valve 710. This causes the bottom of the diaphragm 704 to bulge upwards under the pressure of the gas, and the bulging end of the diaphragm 704 comes into contact with the bottom of the electrode plate 703. This causes the electrode plate 703 to send an electrical activation signal to the alarm body 701.
[0033] In a preferred embodiment: the outer wall shape of the first cylinder 405 is the same as the inner wall shape of the second circular groove 5, and the outer wall of the first cylinder 405 and the inner wall of the second circular groove 5 are slidably fitted together.
[0034] In the above structure, by setting up the first cylinder 405 and the second circular groove 5, the first cylinder 405 can slide along the inner wall of the second circular groove 5.
[0035] In a preferred embodiment: the outer wall shape of the fixing post 414 is the same as the inner wall shape of the arc groove 6, and the outer wall of the fixing post 414 is adapted to the inner wall of the arc groove 6.
[0036] In the above structure, by setting the fixing post 414 and the arc groove 6, when the outer wall of the fixing post 414 comes into contact with the inner wall of the arc groove 6, the fixing post 414, whose outer wall and inner wall have the same shape, will fit and fix with the arc groove 6.
[0037] In a preferred embodiment: the outer wall of the steel wire rope 412 is shaped at a 90-degree angle and is fitted to the outer wall of the take-up reel 411;
[0038] In the above structure, by setting up the take-up pulley 411 and the second wire rope 412, when one end of the second wire rope 412 pulls the fixed column 414, the other end of the second wire rope 412 will be in contact with the outer wall of the take-up pulley 411. The take-up pulley 411 will bend the extension angle of the second wire rope 412 to ninety degrees, so that the outer wall of the other end of the second wire rope 412 will not contact the inner wall of the second cylinder 410 when it extends.
[0039] In a preferred embodiment: there are two of each of the fixed column 414, cylinder 2 410, spring 1 413, wire rope 2 412 and take-up wheel 411, and each fixed column 414, cylinder 2 410, spring 1 413, wire rope 2 412 and take-up wheel 411 are arranged symmetrically with wire rope 1 408 as the center. The inner wall shape of the slide groove 1 406 is the same as the outer wall shape of the slide plate 1 409, and the inner wall of the slide groove 1 406 and the outer wall of the slide plate 1 409 are fitted together and slidably disposed.
[0040] In the above structure, by setting up the fixed column 414, the second cylinder 410, the first spring 413, the second steel wire rope 412, and the take-up wheel 411, pulling the handle 407 will cause one end of the first steel wire rope 408 to extend outward, and the other end of the first steel wire rope 408 will cause the slide plate 409 to slide along the inner wall of the slide groove 406. As the slide plate 409 slides, it will cause the fixed column 414, the second cylinder 410, the first spring 413, the second steel wire rope 412, and the take-up wheel 411, which are symmetrical about the first steel wire rope 408, to move and retract.
[0041] Working principle: During use, when installing the soft sealing body 402 and the hard sealing body 403, the cylinder 405 slides along the inner wall of the circular groove 5. This causes the outer wall of the fixing column 414 to contact the inner wall of the circular groove 5, compressing the spring 413 and moving it towards the inner wall of the cylinder 410. When the outer wall of the fixing column 414 moves to the inner wall of the arc-shaped groove 6, the spring 413 rebounds and fixes the fixing column 414 to the inner wall of the arc-shaped groove 6. This achieves the installation of the soft sealing body 402 and the hard sealing body 403 onto the baffle door body 3. Furthermore, when it is necessary to replace the soft sealing body 402 and the hard sealing body 403... When the handle 407 is pulled, one end of the steel wire rope 408 extends outward, and the other end of the steel wire rope 408 slides the slide plate 409 along the inner wall of the groove 406. The bottom of the slide plate 409 extends one end of the steel wire rope 412, and the other end of the steel wire rope 412 pulls the fixing post 414. The outer wall of the fixing post 414 is separated from the inner wall of the arc groove 6 under the pull of the steel wire rope 412, thereby removing the cylinder 405 from the inner wall of the circular groove 5. This allows for the quick replacement of the soft sealing body 402 and the hard sealing body 403 on the outer wall of the annular mounting block 401.
[0042] Simultaneously, when the gas reaches abnormally high temperatures, the liquid inside the two glass tubes 706 will boil and evaporate, causing the two glass tubes 706 to burst under the pressure of the evaporating gas. Then, under the compression and rebound of the second spring 711, the second slide plate 709 slides along the direction of the second slide groove 708, which will drive the air pipe 707 made of soft PVC to be compressed. This causes the air pipe 707, which has a wavy external shape, to burst during compression. The gas in the cavity is compressed and pushed to the top of the air tube 707 by the valve 710. This causes the bottom of the diaphragm 704 to bulge upwards under the push of the gas, so that the bulging end of the diaphragm 704 comes into contact with the bottom of the electrode plate 703. This causes the electrode plate 703 to send an electrical activation signal to the alarm body 701, so that the alarm body 701 can provide a danger warning to people outside the baffle door body 3, and thus better pre-treat the dangerous gas inside the baffle door body 3.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
