Description

Technical Field

[0001] This utility model relates to the field of aircraft curtain technology, and in particular to a curtain support assembly for use in aircraft. Background Technology

[0002] With the rapid development of China's civil aviation industry, airlines are committed to continuously improving the travel experience for passengers. Currently, curtains have been designed and installed in aircraft cabins. These curtains can physically separate the cabin, providing passengers with shade, privacy, and improved comfort.

[0003] However, when the curtain needs to be inspected or is not needed in the cabin, it needs to be removed from the passenger compartment. The traditional connection method is to use bolts to install and fix the curtain in the cabin. The bolt connection method is inefficient to disassemble, and frequent disassembly and assembly can easily cause the bolt holes to strip, affecting the service life of the curtain support. Utility Model Content

[0004] In view of the above problems, this utility model provides an isolation curtain bracket assembly for use in aircraft.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] An isolation curtain bracket assembly for use in an aircraft is provided, including a fixing strip and a mounting shell. The fixing strip is detachably mounted on the inner wall of the cabin via a first connecting assembly. The mounting shell is detachably connected to the fixing strip via a second connecting assembly. A third connecting assembly for connecting the isolation curtain is provided at the bottom of the mounting shell.

[0007] The second connecting assembly includes a connecting post, a transmission rod, a lever, a transmission block, and a limiting head. A mounting post is fixedly installed on the top of the mounting shell, and an eccentrically formed movable hole is provided on the mounting post. The connecting post is coaxially rotatably installed in the movable hole. The transmission rod is installed inside the mounting shell. At least two connecting posts are provided on the mounting shell. The top end of each connecting post passes through the movable hole and is eccentrically connected to the limiting head, and the bottom end is fixedly connected to the transmission block. The transmission rod and the transmission block are eccentrically hinged. A strip-shaped hole is provided on the outer wall of the mounting shell. The lever passes through the strip-shaped hole and is fixedly connected to the transmission rod. A connecting hole is provided on the fixing strip for the mounting post and the limiting head to pass through.

[0008] Furthermore, the first connecting assembly includes a connecting bolt, a first limiting block, and a hook. A first connecting hook is fixedly provided at one end of the fixing strip. The hook is movably provided at the top end of the fixing strip away from the first connecting hook. A second connecting hook with an opening facing the first connecting hook is provided on the side of the hook away from the first connecting hook. A limiting groove for accommodating the first limiting block is provided on the side of the hook away from the first connecting hook. The connecting bolt passes through the fixing strip and is threadedly connected to the first limiting block.

[0009] Furthermore, the third connecting component includes a guide rail and a second limiting block. The guide rail is located at the bottom of the mounting housing and has an open end. The second limiting block is slidably disposed inside the guide rail and is threaded with a second limiting bolt. The second limiting bolt passes through the second limiting block and abuts against the inner wall of the guide rail.

[0010] Furthermore, the size of the limiting head is no larger than the size of the mounting column, and the limiting head is made coaxial or misaligned with the mounting column by rotating the connecting column.

[0011] Furthermore, a reset assembly is provided inside the mounting housing. The reset assembly includes a mounting block, a reset rod, and a reset spring. The mounting block has a through hole for the reset rod to pass through. The mounting block is fixed inside the mounting housing by screws. One end of the reset rod is hinged to the transmission block. The reset spring is sleeved on the reset rod. The reset spring is used to drive the reset rod to push the transmission rod to rotate so that the limit head is misaligned with the mounting post.

[0012] Furthermore, a limit handle is provided on the outer wall of the mounting housing. One end of the limit handle is rotatably connected to the mounting housing, and the movable end of the limit handle can rotate to align with the end of the moving block in the direction of movement. The limit handle restricts the moving block from sliding in the direction that drives the limit head to rotate and align with the mounting column.

[0013] Furthermore, a connecting shaft is fixedly installed on the outer wall of the mounting housing, a limit handle is installed and rotatably connected to the connecting shaft, a positioning ball is movably installed inside the limit handle, and a drive spring is installed inside the limit handle to drive the positioning ball to move toward the connecting shaft.

[0014] Furthermore, a side curtain support strip for supporting the side curtain of the isolation curtain is fixedly installed on one side of the mounting housing located on the slide rail.

[0015] The beneficial effects of this utility model are as follows: The fixing strip is first installed on the inner wall of the cabin. By sliding the lever, the limiting head on the mounting shell is rotated to be coaxial with the mounting column on the mounting shell. The mounting shell is aligned with the fixing strip, and the limiting head passes through the connecting hole on the fixing strip. Then, the sliding lever is used to make the limiting head and the connecting hole misaligned, so that the mounting shell and the fixing strip can be quickly connected. The mounting shell and the isolation curtain connected to the mounting shell can be quickly removed without disassembling the fixing strip, thereby improving the disassembly efficiency of the isolation curtain in the cabin.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] This application discloses an isolation curtain support assembly for use in aircraft, referring to... Figures 1-4 The system includes a fixing strip 1 and a mounting shell 2. The fixing strip 1 is detachably mounted on the inner wall of the cabin via a first connecting assembly. The mounting shell 2 is detachably connected to the fixing strip 1 via a second connecting assembly. A third connecting assembly for connecting an isolation curtain is provided at the bottom of the mounting shell 2. By first installing the fixing strip 1 inside the cabin, the mounting shell 2 can be quickly attached and detached from the fixing strip 1. The isolation curtain is then mounted on the mounting shell 2, allowing the isolation curtain to be quickly removed without disassembling the fixing strip 1.

[0023] Specifically, the first connecting assembly includes a connecting bolt 41, a first limiting block 42, and a hook 43. One end of the fixing strip 1 is integrally formed with a first connecting hook 12, which is used to connect to a hook rod designed on the top of the cabin. The hook 43 is movably disposed at the top of the fixing strip 1, away from the first connecting hook. The hook 43 has a second connecting hook 431 with an opening facing the first connecting hook. A limiting groove 432 for accommodating the first limiting block 42 is provided on the side of the hook 43 away from the first connecting hook. The connecting bolt 41 passes through the fixing strip 1 and is threadedly connected to the first limiting block 42. In practical use, the first connecting hook 12 on the fixing strip 1 is first hooked onto the inner wall of the cabin. The second connecting hook 431 slides from the side and hooks onto the inner wall of the cabin. The first limiting block 42 is pushed into the limiting groove 432. The connecting bolt 41 passes through the fixing strip 1 and connects to the first limiting block 42, thus effectively fixing the fixing strip 1 to the top of the cabin and preventing it from falling off. In this embodiment, the openings of the first connecting hook 12 and the second connecting hook 431 face each other, which can improve the installation stability of the fixing strip 1.

[0024] In this embodiment, the second connecting component consists of a connecting post 31 and a limiting head 35. The mounting post 21 is integrally fixed to the top of the mounting shell 2, protruding from the mounting shell 2. A connecting hole 11 is provided on the fixing strip 1 for the mounting post and the limiting head 35 to pass through. After the mounting shell 2 is connected to the fixing strip 1, the top end of the mounting post 21 is flush with the top surface of the fixing strip 1. An eccentrically oriented movable hole 22 is provided on the mounting post 21. The connecting post 31 is coaxially rotatably disposed within the movable hole 22. At least two connecting posts 31 are provided on the mounting shell 2. The top end of each connecting post 31 passes through the movable hole 22 and is eccentrically connected to the limiting head 35. By rotating the connecting post 31, the limiting head 35 can be coaxially or eccentrically connected to the mounting post 21. After the mounting shell 2 and the fixing strip 1 are connected, the limiting head 35 protrudes from the top of the fixing strip 1. Then, the connecting column 31 is rotated to make the limiting head 35 eccentric with the mounting column 21, so that the limiting head 35 can be locked onto the top of the fixing strip 1, thus preventing the fixing strip 1 from separating from the mounting shell 2.

[0025] The mounting housing 2 is equipped with a driving component for rotating the connecting columns 31. In this embodiment, the driving component can specifically be a transmission rod 32, a lever 33, and a transmission block 34. The bottom end of each connecting column 31 extends into the mounting housing 2 and is fixedly connected to the transmission block 34. One end of each transmission block 34 is hinged to the transmission rod 32. Through the cooperation between the connecting column 31 and the movable hole 22, and the hinge structure between the transmission rod 32 and the transmission block 34, a parallelogram hinge structure is formed. Moving the transmission rod 32 can simultaneously drive multiple connecting columns 31 to rotate. A strip hole 24 is provided on the outer wall of the mounting housing 2. The lever 33 is located on the outside of the mounting housing 2. After passing through the strip hole 24, the lever 33 is connected to the transmission rod 32 inside the mounting housing 2. The lever 33 can slide along the length direction of the strip hole 24 and move radially along the strip hole 24, so that the horizontal push lever 33 can push the transmission rod 32 to move inside the mounting housing 2 and drive the limit head 35 to move.

[0026] In this embodiment, the size of the limiting head 35 should not be greater than the size of the mounting post 21, so that when the limiting head 35 and the mounting post 21 are coaxially aligned, the limiting post and the mounting post 21 can smoothly pass through the connecting hole 11 on the fixing strip 1. By rotating the connecting post 31, the limiting head 35 can be made coaxial or misaligned with the mounting post 21. Furthermore, the top edge of the limiting head 35 is provided with a guide slope, so that when the mounting shell 2 and the fixing strip 1 are connected, the limiting head 35 can more easily pass through the connecting hole 11.

[0027] Furthermore, a reset assembly is also provided inside the mounting housing 2. Specifically, the reset assembly may include a mounting block 61, a reset rod 62, and a reset spring 63. The mounting block 61 is fixedly installed inside the mounting housing 2 by screws. A through hole is provided on the mounting block 61, through which the reset rod 62 passes. One end of the reset rod 62 is hinged to the transmission block 34. The reset spring 63 is sleeved on the reset rod 62 and is used to drive the reset rod 62 to push the transmission rod 32 to rotate so that the limiting head 35 is eccentrically misaligned with the mounting post 21. In this embodiment, the connecting post 31 is fixedly connected to the middle of the transmission block 34, and the transmission rod 32 and the reset rod 62 are respectively hinged to both ends of the transmission block 34. The through hole size is larger than the reset rod 62 size, which allows the through hole to provide simple guidance for the reset rod 62 while having a margin for the reset rod 62 to deflect within the through hole, allowing the transmission block 34 to rotate normally. By pushing the transmission block 34 to rotate by the reset spring 63, the limiting head 35 can be kept in an eccentric state with the mounting post 21. When the mounting shell 2 is connected to the fixing strip 1, the limiting head 35 is kept in a snap-fit ​​state with the fixing strip 1, thus maintaining a stable connection between the mounting shell 2 and the fixing strip 1.

[0028] Furthermore, a limit handle 71 is rotatably installed on the outer wall of the mounting shell 2. One end of the limit handle 71 is rotatably connected to the mounting shell 2. The movable end of the limit handle 71 can rotate to align with the end of the moving block 33 to restrict the movement of the block 33. The limit handle 71 is damped and rotatably connected to the mounting shell 2. The limit handle 71 restricts the block 33 from sliding in the direction that drives the limit head 35 to rotate and align with the mounting post 21, thereby reducing the possibility of the block 33 being accidentally moved.

[0029] Furthermore, a connecting shaft 72 is fixedly installed on the outer wall of the mounting housing 2. A limiting handle 71 is sleeved and rotatably connected to the connecting shaft 72. A positioning ball 73 is movably installed inside the limiting handle 71. A drive spring 74 is installed inside the limiting handle 71 to drive the positioning ball 73 to move toward the connecting shaft 72. Several positioning grooves 721 are formed on the outer wall of the connecting shaft 72 along its circumference for the positioning ball 73 to engage with. In this embodiment, two positioning grooves 721 are formed, and the positioning ball 73 can be fitted into both positioning grooves 721. When it is in at least one positioning groove 721, the movable end of the limiting handle 71 can be aligned with the limiting block 33.

[0030] In this embodiment, the third connecting component includes a guide rail 51 and a second limiting block 52. The guide rail 51 is disposed at the bottom of the mounting shell 2, with one end open. The second limiting block 52 is slidably disposed within the guide rail 51, and a second limiting bolt is threaded onto the second limiting block 52. The second limiting bolt passes through the second limiting block 52 and abuts against the inner wall of the guide rail 51. A connecting hook can be slidably installed within the guide rail 51, and the connecting hook can attach an isolation curtain. The second limiting block 52 can prevent the connecting hook within the guide rail 51 from detaching from the guide rail 51, thus achieving a detachable connection between the isolation curtain and the mounting shell 2.

[0031] Since the cabin interior has an arc-shaped cross-section on both sides, in order to enable the isolation curtain to cover the edge of the cabin, in this embodiment of the application, a side curtain support strip 23 for supporting the side curtain of the isolation curtain is fixedly installed on one side of the slide rail on the mounting shell 2. The support strip can be adapted to the cabin interior wall, and the top edge of the isolation curtain is designed with mounting holes for the support strip to be inserted. The support strip can support the isolation curtain and maintain the support effect on the isolation curtain.

[0032] Furthermore, an abutment part 8 is also provided on the outer wall of the mounting shell 2 on one side of the fixing strip 1. The top of the abutment part 8 is provided with an anti-collision pad, which can be made of rubber. When the mounting shell 2 is fixed in the cabin, the anti-collision pad and the abutment part 8 abut against the inner wall of the cabin, together with the fixing strip 1 as two support points, to stabilize the mounting shell 2 and prevent the mounting shell 2 from being unstable and shaking during use.
