[0034] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 shown, the embodiment of the present application provides a translational airtight door applicable to a pressurized sleep cabin, including a door frame 100 and a door leaf 200. The door leaf 200 is slidably connected to the door frame 100 in the horizontal direction, and the door leaf 200 opens or closes the door frame 100 when sliding in the horizontal direction; a door lock 500 and a lock seat corresponding to the door lock 500 are connected to the door leaf 200 and the door frame 100, and when the door leaf 200 closes the door frame 100, the door leaf 200 and the door frame 100 are locked or unlocked through the door lock 500.
[0035] Among them, the door frame 100 is a frame structure welded by rectangular tubes. On one side of the door frame 100 facing the door leaf 200, rubber strip receiving grooves 120 corresponding to the four sides of the door leaf 200 are respectively provided on the four sides. A sealing rubber strip 130 is respectively arranged in each rubber strip receiving groove 120. One end of the sealing rubber strip 130 away from the door frame 100 extends out of the rubber strip receiving groove 120; at the top of the door frame 100, a carrying guide rail 110 extending along the sliding direction of the door leaf 200 is provided. The carrying guide rail 110 forms two upper and lower arranged sliding rails 111 with a semi-circular cross-section. A carrying vehicle 310 is slidably arranged in the carrying guide rail 110. The carrying vehicle 310 is respectively connected with four carrying wheels 360 through four core shafts 311 and rolling bearings 312 sleeved on the corresponding core shafts 311. Two carrying wheels 360 rollingly press against the upper sliding rail 111 of the carrying guide rail 110, and two carrying wheels 360 rollingly press against the lower sliding rail 111 of the carrying guide rail 110. Buffer plates 370 are respectively arranged at both ends of the carrying guide rail 110, and buffer sealing plates 380 elastically matched with the two buffer plates 370 are respectively arranged at both ends of the carrying vehicle 310;
[0036] The door leaf 200 is connected to the carrying vehicle 310 through a carrying mechanism 300. The carrying mechanism 300 is configured to be rotatable along a vertical plane perpendicular to the door leaf 200; the carrying mechanism 300 includes a door carrying frame 320 and two connection brackets 330 respectively connected to both ends of the top of the door leaf 200. Both ends of the bottom of the door carrying frame 320 are respectively connected to the two connection brackets 330 through rotating shafts 321 that can rotate along a horizontal axis. Both ends of the top of the door carrying frame 320 are respectively connected with connection shafts 350 that can rotate along a horizontal axis through spherical plain bearings 340. The two connection shafts 350 are respectively connected to both ends of the carrying vehicle 310.
[0037] The door leaf 200 is a frame structure welded by rods. Reinforcing ribs are connected between two adjacent rods. Rib plates 210 are respectively protruded on the outer walls of the inner side and the outer side of the door leaf 200. A layer of skin 220 is respectively wrapped on the inner side and the outer side of the door leaf 200. The edges of the two layers of skin 220 are respectively bent to wrap the rib plates 210 protruded on the outer walls of the inner side and the outer side of the door leaf 200. An observation hole 230 is provided in the middle of the door leaf 200. An observation window frame 240 is connected in the observation hole 230. Glass 250 is arranged in the observation window frame 240. The glass 250 is double-layer insulating glass. Glass sealing rubber strips 260 are respectively arranged between the inner wall and the outer wall of the glass 250 and the observation window frame 240; Card slots 270 are respectively provided at both ends of the door leaf 200, and end buffer rubber strips 280 extending to the outside are respectively connected in the card slots 270. A rotatable and elastic balance wheel pressing block 140 is connected to the carrying guide rail 110, and a rotatable balance wheel 290 is connected to the door leaf 200; when the door leaf 200 moves to close the door frame 100, the balance wheel pressing block 140 presses and limits the position of the balance wheel 290.
[0038] The door frame 100 and the door leaf 200 are connected through a guiding mechanism; the guiding mechanism includes three guiding rails 400 and three guiding wheels 420 corresponding to the guiding rails 400 one by one. Among them, two guiding rails 400 are connected to the bottom of the bearing rail 110, and one guiding rail 400 is connected to the bottom of the door leaf 200 through a rail mounting plate 480. Two connecting brackets 330 at the top of the door leaf 200 are respectively connected with a guiding wheel 420 through a guiding wheel bracket 410, and one guiding wheel 420 is connected to the bottom of the door frame 100 through a guiding wheel bracket 410. The guiding wheel 420 connected to the connecting bracket 330 rolls in the guiding rail 400 connected to the bearing rail 110, and the guiding wheel 420 connected to the door frame 100 rolls in the guiding rail 400 connected to the door leaf 200. Each guiding rail 400 includes a linear rail section 430 and an arc rail section 440 connected in sequence; when the door leaf 200 moves to open or close the door frame 100, the arc rail section 440 of the guiding rail 400 in the guiding mechanism presses against the guiding wheel 420 to guide the door leaf 200 to move away from or close to the door frame 100 to loosen or compress each sealing strip 130;
[0039] In this embodiment, the guiding mechanism further includes a wedge block 450 connected to the door leaf 200 and a wedge fixing block 460 corresponding to the wedge block 450 one by one. The door frame 100 is connected to the wedge fixing block 460 through a wedge block bracket 470; when the door leaf 200 moves to close the door frame 100, the wedge fixing block 460 presses against the wedge block 450 and pushes the door leaf 200 to move towards the door frame 100 to compress the sealing strip 130.
[0040] The working principle of the translational airtight door applicable to the pressurized sleep cabin provided by the embodiment of the present application is that when the user pushes the door leaf 200 to move horizontally to close the door frame 100, the door leaf 200 moves and drives the carrier vehicle 310 to move along the carrier guide rail 110 provided at the top of the door frame 100 through the connecting bracket 330 and the door carrier 320 connected to the top. At the same time, the two connecting brackets 330 at the top of the door leaf 200 respectively move along the linear guide rail section 430 in the guide rail 400 connected to the bottom of the carrier guide rail 110 through the guide wheels 420 connected by the guide wheel brackets 410, and the guide wheels 420 connected to the bottom of the door frame 100 through the guide wheel brackets 410 move along the linear guide rail section 430 in the guide rail 400 connected to the bottom of the door leaf 200. When the door leaf 200 moves horizontally to close the door frame 100, the door leaf 200 moves and drives the connecting bracket 330 and the door carrier 320 to drive the carrier vehicle 310 to move along the carrier guide rail 110 until the buffer sealing plate 380 provided at one end of the carrier vehicle 310 impacts the buffer plate 370 at one end of the carrier guide rail 110. During this process, the arc guide rail section 440 in the guide rail 400 connected to the bottom of the carrier guide rail 110 and the arc guide rail section 440 in the guide rail 400 connected to the bottom of the door leaf 200 respectively press against the guide wheels 420 connected by the guide wheel brackets 410 of the two connecting brackets 330 at the top of the door leaf 200 and the guide wheels 420 connected to the bottom of the door frame 100 through the guide wheel brackets 410. Thus, through the pressing operation, while the door leaf 200 moves horizontally, it also moves towards the direction close to the door frame 100, so that when the door leaf 200 moves horizontally to close the door frame 100, it also moves towards the direction close to the door frame 100, making the four sides of the door leaf 200 respectively press against the sealing rubber strips 130 in the rubber strip receiving grooves 120 on the four sides of the door frame 100, and when the door leaf 200 closes the door frame 100, the four sides simultaneously and evenly squeeze the sealing rubber strips 130 on the four sides of the door frame 100 to improve the sealing performance.
[0041] Among them, when the door leaf 200 moves to close the door frame 100, the wedge-shaped fixing block 460 connected to the door frame 100 will also press against the wedge-shaped block 450 connected to the door leaf 200 and push the door leaf 200 to move towards the direction close to the door frame 100 to press the sealing rubber strip 130. After the pressurizing equipment makes the internal pressure in the pressurized sleep cabin higher than the outside of the cabin, the door leaf 200 will further press the sealing rubber strip 130 due to the action of the internal and external pressure difference to ensure the sealing performance. At the same time, using the translational door leaf 200 to open and close the door frame 100 can reduce the space required for opening and closing.
[0042] In addition, after using two layers of skins 220 to wrap the inner wall and the outer wall of the door leaf 200 respectively and then bending to wrap the ribs 210 formed on the inner and outer sides of the outer peripheral wall of the door leaf 200, on the one hand, it can improve the structural strength and airtight performance of the door leaf 200 while reducing the weight of the door leaf 200. On the other hand, it meets the requirements of high strength and high stiffness of the door leaf 200 for the internal and external pressure difference in the pressurized cabin.
[0043] The carrying mechanism 300 can adjust the position of the door leaf 200 by rotating the door carrier 320, by connecting the top and bottom of the door carrier 320 to the connecting bracket 330 at the top of the door leaf 200 and the carrier vehicle 310 through two rotating shafts 321 and a connecting shaft 350 respectively, ensuring that the position of the door leaf 200 relative to the door frame 100 can be adjusted flexibly and conveniently during installation, making the installation and debugging of the door leaf 200 more convenient. The carrying guide rail 110 is connected with a rotatable elastic balance wheel pressing block 140, and the door leaf 200 is connected with a rotatable balance wheel 290. When the door leaf 200 moves to close the door frame 100, the balance wheel 290 rolls to press the balance wheel pressing block 140 to rotate and cross over the balance wheel pressing block 140, and then the balance wheel pressing block 140 after elastic reset presses and limits the position of the balance wheel 290 again, so that the door leaf 200 is limited in the vertical direction after closing.
[0044] An observation hole 230 is provided in the middle of the door leaf 200, an observation window frame 240 is connected in the observation hole 230, and a glass 250 is provided in the observation window frame 240, which can facilitate users to observe inside and outside through the glass 250. At the same time, glass sealing rubber strips 260 are respectively provided between the inner and outer walls of the glass 250 and the observation window frame 240, which can effectively improve the sealing performance and avoid air leakage.
[0045] In other alternative embodiments, sealing rubber strips 130 can also be respectively provided on the four sides of the side of the door leaf 200 facing the door frame 100, or sealing rubber strips 130 can be respectively provided on the four sides of the side of the door leaf 200 facing the door frame 100 and the four sides of the side of the door frame 100 facing the door leaf 200 at the same time. When the door leaf 200 moves to open and close the door frame 100, it moves away from or towards the door frame 100 to loosen or press each sealing rubber strip 130 to achieve contact sealing or sealed connection.
[0046] In other alternative embodiments, the guiding mechanism can also be provided with one or more guiding guide rails 400 and a plurality of corresponding guiding wheels 420. The guiding guide rails 400 are provided on the door leaf 200 or the door frame 100, and the corresponding guiding wheels 420 are respectively connected to the door frame 100 or the door leaf 200. Each guiding wheel 420 rolls in a guiding guide rail 400; when moving to close the door frame 100, the arc-shaped rail section 440 of the guiding guide rail 400 presses against the guiding wheel 420 and pushes the door leaf 200 to move towards the door frame 100 to press the sealing rubber strip 130.
[0047] In other alternative embodiments, the guiding mechanism may further be provided with at least one wedge block 450 and a wedge fixing block 460 corresponding to the wedge block 450 one by one. The wedge block 450 is disposed on the door leaf 200 or the door frame 100, and the corresponding wedge fixing blocks 460 are respectively disposed on the door frame 100 or the door leaf 200. When the door frame 100 is moved to be closed, the wedge fixing block 460 presses against the wedge block 450 and pushes the door leaf 200 to move towards the door frame 100 to compress the sealing strip 130.
