Description

Technical Field

[0001] This application relates to the field of linkage door technology, and in particular to a linear track linkage door that prevents swaying. Background Technology

[0002] A linkage door consists of a fixed door and multiple movable doors. When one movable door moves, the other movable doors can also move simultaneously to open or close. Compared with traditional sliding doors, linkage doors save space and allow for a larger opening space.

[0003] Regarding the aforementioned technologies, among existing linkage doors, there are three-linkage sliding doors without a bottom track. Generally, when the width of the sliding door exceeds 800 mm, the stability of the door leaf will be weakened, causing the center of gravity of the door panel to be unstable during movement, resulting in the door panel wobbling when moving. Over a long period of time, this will also cause certain damage to the slide rail. Summary of the Invention

[0004] In order to achieve the effect of smooth movement of the linkage door without shaking, this application provides a linear track linkage door that prevents swaying.

[0005] The linear track linkage door for preventing swaying provided in this application adopts the following technical solution:

[0006] A linear track linkage door for preventing swaying includes a ceiling slide rail, a fixed linkage door fixed to the ceiling slide rail, and a first movable linkage door and a second movable linkage door slidably connected to the ceiling slide rail. The fixed linkage door, the first movable linkage door, and the second movable linkage door are arranged sequentially along the width direction of the ceiling slide rail. A lower slide rail is provided at the bottom of each of the fixed linkage door, the first movable linkage door, and the second movable linkage door. Each lower slide rail is provided with a connecting rod, and each connecting rod is rotatably connected to a guide wheel. Each connecting rod, in cooperation with the corresponding guide wheel, hooks onto an adjacent lower slide rail, and the guide wheel is slidably disposed within the hooked lower slide rail. The first movable linkage door, the second movable linkage door, and the fixed linkage door can all slide relative to each other.

[0007] Furthermore, when closing the doorway, after the first movable door and the second movable door are completely offset, the second movable door and the first movable door move simultaneously.

[0008] When the doorway is opened, after the first movable door and the second movable door are completely overlapped, the second movable door and the first movable door move simultaneously.

[0009] By adopting the above technical solution, when closing the doorway, the second movable door is pulled to move along the length of the ceiling slide rail. The connecting rod of the second movable door, in conjunction with the corresponding guide wheel, hooks onto the slide rail of the first movable door. During the movement of the second movable door, its guide wheel moves along the lower slide rail of the first movable door.

[0010] Meanwhile, the connecting rod of the first movable door, in conjunction with the corresponding guide wheel, hooks onto the lower slide rail of the second movable door, and its guide wheel moves relative to the lower slide rail of the second movable door, thereby restricting the width of the bottom of the second movable door and constraining the width of the top of the second movable door by the ceiling slide rail. While being constrained, it also plays a guiding role, allowing the second movable door to slide smoothly without shaking during movement.

[0011] Similarly, when closing the doorway, once the first and second movable doors are completely offset, the movement of the second movable door causes the first movable door to move simultaneously. The connecting rod of the first movable door, in conjunction with the corresponding guide wheel, hooks onto the fixed and second movable doors. The connecting rods of the second movable and fixed doors, in conjunction with the corresponding guide wheel, hook onto the first movable door, thus constraining the width of the bottom of the first movable door during its movement. While being constrained, the first movable door also serves as a guide, allowing it to slide smoothly without wobbling during its movement.

[0012] Similarly, when the doorway is open, the second movable door, under the action of its connecting rod and guide wheel, and in conjunction with the connecting rod and guide wheel of the first movable door, moves smoothly. When the first and second movable doors overlap, they move smoothly simultaneously. This achieves the effect of smooth movement of the interlocking door during opening and closing without shaking.

[0013] Optionally, the lower slide rail includes an installation rail and two sliding rails. The installation rail is located between the two sliding rails, and both ends of the installation rail are open. The installation rails of both the fixed connecting door and the second movable connecting door are provided with fixing members, which are used to connect with the connecting rod.

[0014] By adopting the above technical solution, the fastener can be inserted into the mounting rail from the end of the mounting rail, which is convenient for installation. The guide wheel is set in the adjacent sliding rail to avoid interference between the adjacent guide wheel and the fastener during movement. This allows the first movable door, the second movable door, and the fixed door to be completely staggered or completely overlapped. When the doorway is closed, the unfolding area of ​​the linkage door is increased, which helps to save door frame material. When the doorway is opened, the area occupied by the linkage door is reduced, allowing the doorway to have a larger open space.

[0015] Optionally, decorative panels are installed at the bottom of the fixed connecting door, the first movable connecting door, and the second movable connecting door. The decorative panels enclose the ends of the sliding rail and the mounting rail. The decorative panels are fixed to the connecting rod of the second movable connecting door. The elevation of the connecting rod of the second movable connecting door is higher than the elevation of the connecting rod of the first movable connecting door and the connecting rod of the fixed connecting door.

[0016] By adopting the above technical solution, during the relative movement of the first movable door and the second movable door, the connecting rod of the first movable door can pass over the connecting rods of the second movable door and the fixed door, thus avoiding interference between the connecting rods of the first movable door and the second movable door and the fixed door.

[0017] Optionally, the connecting rod is installed on the fixing member at one end of the fixed door near the doorway entrance, and the guide wheel of the connecting rod is located in the sliding rail on the side of the first movable door near the fixed door;

[0018] The decorative panel near the entrance / exit of the first movable door is fitted with the connecting rod, and the guide wheel of the connecting rod is located in the sliding rail of the second movable door near the first movable door.

[0019] The connecting rod is installed on the fixing member of the second movable door away from the doorway entrance and exit, and the guide wheel of the connecting rod is located on the sliding rail of the first movable door near the second movable door;

[0020] The connecting rod is installed on the decorative panel at the end of the first movable door away from the doorway entrance, and the guide wheel of the connecting rod is located in the sliding rail on the side of the fixed door closer to the first movable door.

[0021] By adopting the above technical solution, the first movable door is hooked on both sides by the connecting rod and guide wheel of the fixed door, and the connecting rod and guide rod of the second movable door, respectively. The first movable door also hooks onto the fixed door and the second movable door in the opposite direction. During movement, both ends of the first movable door are always constrained by the connecting rod and guide wheel, allowing for smoother movement. When the second movable door is completely separated from the first movable door, the end of the second movable door near the doorway is not constrained by the connecting rod and guide wheel. However, due to the interaction between the first and second movable doors, the movement of the second movable door is also smoother when the first movable door moves more smoothly, reducing the likelihood of swaying when the first and second movable doors are fully open.

[0022] Optionally, the fixing member of the fixed door is threadedly connected to a first adjusting screw, the first adjusting screw is coaxially fixed to a first adjusting nut, a fixing seat is provided below the fixed door, the first adjusting screw passes through the fixing seat, and the first adjusting nut is supported on the fixing seat;

[0023] The bottom of the ceiling slide rail is provided with a fixing plate, and the fixing plate is threadedly connected to a second adjusting screw. The second adjusting screw passes through the top of the fixed door and provides support for the fixed door. The second adjusting screw is coaxially fixed with a second adjusting nut, which is located between the fixing plate and the fixed door.

[0024] By adopting the above technical solution, the first adjusting nut and the second adjusting nut are rotated simultaneously, causing the first adjusting screw and the second adjusting screw to rotate, thereby realizing the raising and lowering of the fixed connecting door, which facilitates the adjustment of the distance between the fixed connecting door and the ground.

[0025] Optionally, the ceiling slide rail is equipped with pulley carts, and there are several pulley carts. The pulley carts are divided into two groups according to their number. One group of pulley carts is located above the first movable door, and the other group of pulley carts is located above the second movable door. A third adjusting screw is provided in the pulley cart. The third adjusting screw located above the first movable door passes through the first movable door and provides support for it. The third adjusting screw located above the second movable door passes through the second movable door and provides support for it.

[0026] A first bevel gear sleeve is rotatably connected inside the pulley carriage. The third adjusting screw is threadedly connected to the first bevel gear sleeve. A rotating shaft is rotatably provided inside the pulley carriage. The rotating shaft is inclined and extends inclinedly towards one end face of the sliding wheel. An adjusting groove is opened at the end of the rotating shaft extending out of the sliding wheel. A second bevel gear sleeve is coaxially fixed at the end of the rotating shaft near the third adjusting screw. The first bevel gear sleeve meshes with the second bevel gear sleeve.

[0027] By adopting the above technical solution, the third adjusting screw suspends the first and second movable doors. The adjusting tool is inserted into the adjusting groove and the rotating shaft is rotated. The rotating shaft drives the second bevel gear sleeve to rotate, and the second bevel gear sleeve drives the first bevel gear sleeve to rotate, thereby realizing the rotation of the third adjusting screw. The third adjusting screw drives the first and second movable doors to rise and fall. Because the rotating shaft is set at an inclination, it is convenient to insert the adjusting tool into the adjusting groove, reducing interference between the adjusting tool and the door frames of the first and second movable doors during the adjustment process, and facilitating the adjustment of the distance between the first and second movable doors and the ground.

[0028] Optionally, buffer components are provided at both ends of the ceiling slide rail, and a first abutting block is provided on the pulley. When the second movable door moves close to the edge of the opening, the first abutting block cooperates with the buffer components to decelerate the second movable door.

[0029] By adopting the above technical solution, when the second movable door approaches the edge of the opening, the first abutting block, in conjunction with the buffer, slows down the pulley, thereby slowing down the second movable door and preventing the second movable door from violently impacting the edge of the opening and causing damage to the door frame.

[0030] Optionally, the buffer includes a mounting plate disposed within the ceiling slide rail. A telescopic sleeve is provided on the mounting plate, and a guide rod is slidably disposed within the telescopic sleeve. A sliding block is provided at one end of the guide rod away from the telescopic sleeve, and a buffer spring is provided on the side of the sliding block away from the guide rod. The end of the buffer spring away from the sliding block is fixed to the mounting plate. A fixing rod is connected to the sliding block, and a second abutting block is provided on the fixing rod. The second abutting block is disposed opposite to the first abutting block.

[0031] By adopting the above technical solution, when the pulley cart drives the first abutting block to contact the second abutting block, as the pulley cart continues to move towards the edge of the doorway, the second abutting block drives the fixed rod and the sliding block to move. The sliding block drives the guide rod to gradually penetrate into the telescopic sleeve. At the same time, the sliding block drives the buffer spring to compress, thereby decelerating the first abutting block and the pulley cart, thus decelerating the second moving door.

[0032] Optionally, the ceiling slide rail is slidably equipped with an indicator sign, which can slide vertically. The ceiling slide rail is equipped with a moving block that moves along the length of the ceiling slide rail. The ceiling slide rail is equipped with a return spring that is connected to the moving block. The indicator sign and the moving block are connected by a linkage. During the closing process of the first movable door, the first movable door pushes the moving block to move, and the moving block drives the linkage to move, causing the indicator sign to extend downwards out of the ceiling slide rail. When the first movable door is fully closed, the indicator sign moves to its limit distance.

[0033] By adopting the above technical solution, when the first movable door closes the doorway, the first movable door pushes the movable block, and the movable block drives the indicator sign to extend downwards from the ceiling slide rail through the linkage component, so that people can easily see the indicator sign that the doorway is closed and avoid accidentally hitting the glass of the linkage door. When the first movable door opens, the reset spring drives the movable block to reset, causing the indicator sign to rise and reset.

[0034] Optionally, the linkage includes a first link rotatably connected to the side of the indicator sign opposite to the movable block; a second link rotatably connected to the ceiling slide rail; the indicator sign located between the first and second links; the first and second links rotatably connected via a connecting shaft; and a third link hinged to the end of the second link away from the first link, the third link being hinged to the movable block.

[0035] By adopting the above technical solution, when the moving block moves, it drives the third connecting rod to move and swing. The third connecting rod drives the second connecting rod to rotate, and the second connecting rod drives the first connecting rod to swing and move downward, thereby realizing that the first connecting rod drives the signboard to move downward and extend out of the ceiling slide rail.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. Under the action of the connecting rod and the guide wheel, the width direction of the bottom of the first and second movable doors is constrained, and the width direction of the top of the first and second movable doors is constrained by the ceiling slide rail. While being constrained, the guide wheel can also play a guiding role, so that the first and second movable doors can slide smoothly during the movement, and the linkage door can move smoothly without shaking.

[0038] 2. After the pulley cart brings the first abutting block into contact with the second abutting block, as the pulley cart continues to move closer to the edge of the doorway, the second abutting block moves the fixed rod and the sliding block. The sliding block moves the guide rod deeper into the telescopic sleeve, and at the same time, the sliding block compresses the buffer spring, thereby slowing down the first abutting block and the pulley cart, thus slowing down the second moving door and preventing the second moving door from violently hitting the edge of the doorway and causing damage to the door frame.

[0049] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0050] This application discloses a linear track linkage door that prevents swaying.

[0051] like Figure 1 and Figure 2 A linear track linkage door for preventing swaying includes a ceiling slide rail 1, which is a three-track slide rail. Two fixing plates 11 are welded to the end of the first row of slide rails away from the door opening. Two pulleys 2 are slidably installed in the second and third rows of slide rails of the ceiling slide rail 1. A first abutment block 21 is installed on the top of each pulley 2. Buffers 3 are installed and fixed at both ends of the third row of slide rails of the ceiling slide rail 1. The first abutment block 21 is used to cooperate with the buffers 3 to drive the pulleys 2 of the third row of slide rails of the ceiling slide rail 1 to decelerate.

[0052] The fixing plate 11 is threadedly connected to the second adjusting screw 12, and the second adjusting screw 12 is coaxially fixed to the second adjusting nut 13. A fixed connecting door 4 is provided below the first row of sliding rails of the ceiling slide rail 1. The second adjusting screw 12 passes through the fixed connecting door 4 and the end of the second adjusting screw 12 supports the fixed connecting door 4, so that the fixed connecting door 4 is suspended below the ceiling slide rail 1.

[0053] The pulley trolley 2 is internally threaded with a third adjusting screw 22. The third adjusting screw 22 passes through the bottom of the pulley trolley 2 and through the ceiling slide rail 1. A first movable connecting door 5 is provided below the second row of slide rails of the ceiling slide rail 1. The first movable connecting door 5 corresponds to the two pulley trolleys 2 of the second row of slide rails of the ceiling slide rail 1. The third adjusting screw 22 of the corresponding pulley trolley 2 passes through the top of the first movable connecting door 5, and the end of the corresponding third adjusting screw 22 supports the first movable connecting door 5, so that the first movable connecting door 5 is suspended below the ceiling slide rail 1.

[0054] A second movable door 6 is provided below the third row of slide rails of the ceiling slide rail 1. The second movable door 6 corresponds to the two pulleys 2 of the third row of slide rails of the ceiling slide rail 1. The third adjusting screw 22 of the corresponding pulley 2 passes through the top of the second movable door 6, and the end of the corresponding third adjusting screw 22 supports the second movable door 6, so that the second movable door 6 is suspended below the ceiling slide rail 1.

[0055] like Figure 3 A rotating shaft 23 is rotatably connected inside the pulley cart 2. Two rotating shafts 23 in the same row of tracks are inclined towards the doorway edge closest to them, and one end of the rotating shaft 23 extends out from one side of the pulley cart 2. A first bevel gear sleeve 24 is coaxially fixed to one end of the third adjusting screw 22 inside the pulley cart 2, and a second bevel gear sleeve 25 is coaxially fixed to one end of the rotating shaft 23 near the third adjusting screw 22. The first bevel gear sleeve 24 and the second bevel gear sleeve 25 mesh with each other. An adjusting groove 231 is provided at the end of the rotating shaft 23 extending out of the pulley cart 2 to facilitate the rotation of the rotating shaft 23.

[0056] like Figure 2 ,、 Figure 4 and Figure 5 A movable block 14 is slidably installed in the second row of the ceiling slide rail 1. An installation plate 17 is installed on the second row of the ceiling slide rail 1. A return spring 16 is installed on the installation plate 17. The return spring 16 is fixed to the movable block 14 on the side away from the first movable door 5. An indicator 15 is slidably connected to the second row of the ceiling slide rail 1. The indicator 15 moves up and down in the vertical direction. The indicator 15 and the movable block 14 are connected by a linkage 7. When the first movable door 5 is closed, the first movable door 5 pushes the movable block 14 to move. The movable block 14 drives the linkage 7 to move, causing the indicator 15 to extend downward out of the ceiling slide rail 1.

[0057] like Figure 1 , Figure 6 and Figure 7 The bottom of the fixed interlocking door 4, the first movable interlocking door 5, and the second movable interlocking door 6 are all provided with a lower slide rail 8. The lower slide rail 8 includes an installation rail 81 and two sliding rails 82. The installation rail 81 is located between the two sliding rails 82. Both ends of the installation rail 81 and the lower slide rail 8 are open.

[0058] Two fasteners 9 are installed at both ends of the mounting rail 81 of the first movable door 5, the second movable door 6 and the fixed door 4. The fasteners 9 include plug-in blocks 91, which are inserted into the mounting rail 81. The bottom of the plug-in blocks 91 is bolted to a fixing block 92.

[0059] The bottom ends of the first movable door 5, the second movable door 6, and the fixed door 4 are all provided with decorative panels 10. The decorative panels 10 close the ends of the corresponding mounting rails 81 and sliding rails 82, and the decorative panels 10 are bolted to the corresponding plug-in blocks 91.

[0060] The first adjusting screw 83 is bolted to the plug block 91 inside the mounting rail 81 of the fixed door 4. The first adjusting screw 83 is coaxially fixed to the first adjusting nut 84. A fixed seat 85 is provided below the fixed door 4. The fixed seat 85 is bolted to the ground. The first adjusting screw 83 passes through the fixed seat 85, and the first adjusting nut 84 is supported on the fixed seat 85.

[0061] A connecting rod 86 is bolted to the fixing block 92 at the end of the second movable door 6 away from the doorway entrance. The connecting rod 86 is an L-shaped rod. A guide wheel 87 is rotatably connected to the end of the connecting rod 86 away from the second movable door 6. The guide wheel 87 is slidably set in the sliding rail 82 of the first movable door 5 near the second movable door 6.

[0062] A connecting rod 86 is welded to the decorative panel 10 at the end of the first movable door 5 away from the doorway entrance. The connecting rod 86 is installed on the side of the decorative panel 10 close to the fixed door 4. The connecting rod 86 is rotatably connected to a guide wheel 87. The guide wheel 87 is slidably set in the sliding rail 82 of the fixed door 4 close to the first movable door 5.

[0063] A connecting rod 86 is bolted to a fixing block 92 at one end of the fixed door 4 near the entrance / exit of the doorway. A guide wheel 87 is rotatably connected to the end of the connecting rod 86 away from the fixed door 4. The guide wheel 87 is slidably disposed in the sliding rail 82 of the first movable door 5 near the fixed door 4.

[0064] A connecting rod 86 is welded to the decorative panel 10 at the end of the first movable door 5 near the entrance / exit of the doorway. The connecting rod 86 is installed on the side of the decorative panel 10 near the second movable door 6. The connecting rod 86 is rotatably connected to a guide wheel 87. The guide wheel 87 is slidably disposed in the sliding rail 82 of the second movable door 6 near the first movable door 5.

[0065] The bottom elevation of the crossbar section of the first movable door 5 is higher than the top elevation of the crossbar section of the other connecting rods 86.

[0066] When the doorway is fully open, the first movable door 5, the second movable door 6, and the fixed door 4 are completely overlapped.

[0067] When the doorway is completely closed, the first movable door 5, the second movable door 6, and the fixed door 4 are completely staggered.

[0068] Before installing the decorative panel 10 and the connecting rod 86, first adjust the first adjusting nut 84 and second adjusting nut 13 simultaneously to rotate the first adjusting screw 83 and second adjusting screw 12, thereby raising and lowering the fixed connecting door 4 and facilitating the adjustment of the distance between the fixed connecting door 4 and the ground.

[0069] Then, the adjusting tool is inserted into the adjusting groove 231 and the rotating shaft 23 is rotated. The rotating shaft 23 drives the second bevel gear sleeve 25 to rotate, and the second bevel gear sleeve 25 drives the first bevel gear sleeve 24 to rotate, thereby realizing the rotation of the third adjusting screw 22. The third adjusting screw 22 drives the first movable door 5 and the second movable door 6 to rise and fall. Since the rotating shaft 23 is set at an angle, it is convenient to insert the adjusting tool into the adjusting groove 231, reducing the interference between the adjusting tool and the door frame of the first movable door 5 and the second movable door 6 during the adjustment process. It is convenient to adjust the distance of the first movable door 5 and the second movable door 6 from the ground, so that the top and bottom of the first movable door 5, the second movable door 6 and the fixed door 4 are flush with each other.

[0070] When closing the doorway, pulling the connecting rod 86 at the end of the second movable door 6 away from the doorway entrance causes the guide wheel 87 to move along the sliding rail 82 of the first movable door 5. As the second movable door 6 moves, the connecting rod 86 and guide wheel 87 of the first movable door 5, located near the second movable door 6, hook onto the sliding rail 82 of the second movable door 6, and the guide wheel 87 slides relative to the sliding rail 82 within the second movable door 6. This restricts the width of the bottom of the second movable door 6 and constrains the width of the top of the second movable door 6 by the ceiling sliding rail 1. While constrained, the rail also provides guidance, allowing the second movable door 6 to slide smoothly without wobbling during movement.

[0071] When the second movable door 6 moves to a position completely offset from the first movable door 5, the connecting rod 86 of the second movable door 6 is located directly above the connecting rod 86 on the side of the first movable door 5 closest to the second movable door 6, and the guide wheel 87 of the second movable door 6 abuts against the decorative panel 10 of the first movable door 5 near the doorway.

[0072] When the second movable door 6 is pulled to move, the second movable door 6 drives the first movable door 5 to move. The guide wheel 87 of the first movable door 5, which is away from the entrance / exit of the doorway, slides within the sliding rail 82 of the fixed door 4. As the first movable door 5 moves, the guide wheel 87 of the fixed door 4, which is near the entrance / exit of the doorway, slides relative to the first movable door 5 within the sliding rail 82 of the fixed door 4. This restricts the width of the bottom of the second movable door 6 and constrains the width of the top of the second movable door 6 by the ceiling sliding rail 1. While being constrained, the rail also provides guidance, allowing the second movable door 6 to slide smoothly without wobbling during movement.

[0073] Similarly, when the doorway is open, the second movable door 6, under the action of its connecting rod 86 and guide wheel 87, and in conjunction with the connecting rod 86 and guide wheel 87 of the first movable door 5, moves smoothly. When the first movable door 5 and the second movable door 6 overlap, the second movable door 6, under the action of its connecting rod 86 and guide wheel 87, and in conjunction with the connecting rod 86 and guide wheel 87 of the fixed door 4, moves smoothly simultaneously. This achieves the effect of smooth movement of the interlocking door during opening and closing without shaking.

[0074] When the second movable door 6 approaches the edge of the opening, the first abutting block 21, in conjunction with the buffer 3, slows down the pulley 2, thereby slowing down the second movable door 6 and preventing the second movable door 6 from violently impacting the edge of the opening and causing damage to the door frame.

[0075] When the first movable door 5 closes the doorway, it pushes the movable block 14 closer to the mounting plate. The movable block 14, through the linkage 7, causes the indicator 15 to extend downwards from the ceiling slide rail 1, making it easy for people to see the indicator 15 indicating that the doorway is closed, thus avoiding accidental impact to the glass of the movable door. When the first movable door 5 opens, the return spring 16 causes the movable block 14 to return to its original position, causing the indicator 15 to rise and return to its original position.

[0076] like Figure 8 and Figure 9The buffer component 3 includes a mounting plate 31, which is fixedly installed at the end of the third row of slide rails of the ceiling slide rail 1. A telescopic sleeve 32 is fixed on the mounting plate 31, and a guide rod 33 is coaxially inserted into the telescopic sleeve 32. A sliding block 34 is fixed to the end of the guide rod 33 away from the telescopic sleeve 32. A buffer spring 35 is fixedly installed on the side of the sliding block 34 away from the guide rod 33. The end of the buffer spring 35 away from the sliding block 34 is fixed to the mounting plate 31. The buffer spring 35 and the guide rod 33 are parallel to each other. A fixing rod 36 is fixedly connected to the sliding block 34. The fixing rod 36 is located between the buffer spring 35 and the guide rod 33, and the fixing rod 36 is parallel to the guide rod 33. A second abutment block 37 is fixed to the end of the fixing rod 36 away from the sliding block 34. The second abutment block 37 corresponds to the first abutment block 21.

[0077] When the pulley trolley 2 drives the first abutting block 21 to contact the second abutting block 37, as the pulley trolley 2 continues to move closer to the edge of the doorway, the second abutting block 37 drives the fixed rod 36 and the sliding block 34 to move. The sliding block 34 drives the guide rod 33 to gradually penetrate into the telescopic sleeve 32. At the same time, the sliding block 34 drives the buffer spring 35 to compress, thereby decelerating the first abutting block 21 and the pulley trolley 2, thus decelerating the second moving door 6.

[0078] like Figure 4 and Figure 5 The linkage 7 includes a first link 71, which is rotatably connected to the side of the indicator 15 away from the moving block 14. The second row of the ceiling slide rail 1 is rotatably connected to a second link 72. The indicator 15 is located between the first link 71 and the second link 72. The end of the first link 71 away from the indicator 15 and the end of the second link 72 are rotatably connected through a connecting shaft 73. The end of the second link 72 away from the first link 71 is connected to a third link 74. The third link 74 is hinged to the side of the moving block 14.

[0079] When the moving block 14 moves, it drives the third connecting rod 86 to move and swing. The third connecting rod 74 drives the second connecting rod 72 to rotate. The second connecting rod 72 drives the first connecting rod 71 to swing and move downward, thereby enabling the first connecting rod 71 to drive the sign 15 to move downward and extend out of the ceiling slide rail 1.

[0080] The implementation principle of this application embodiment is as follows: when closing the doorway, the second movable door 6 is pulled to move along the length direction of the ceiling slide rail 1. The connecting rod 86 of the second movable door 6, in conjunction with the corresponding guide wheel 87, hooks onto the slide rail of the first movable door 5. During the movement of the second movable door 6, its guide wheel 87 moves along the lower slide rail 8 of the first movable door 5.

[0081] Meanwhile, the connecting rod 86 of the first movable door 5, in conjunction with the corresponding guide wheel 87, hooks onto the lower slide rail 8 of the second movable door 6, and the guide wheel 87 moves relative to the lower slide rail 8 of the second movable door 6, thereby restricting the width of the bottom of the second movable door 6 and constraining the width of the top of the second movable door 6 by the ceiling slide rail 1. While being constrained, it also plays a guiding role, so that the second movable door 6 can slide smoothly without shaking during the movement.

[0082] Similarly, when closing the doorway, once the first movable door 5 and the second movable door 6 are completely offset, the movement of the second movable door 6 causes the first movable door 5 to move simultaneously. The connecting rod 86 of the first movable door 5, in conjunction with the corresponding guide wheel 87, hooks the fixed door 4 and the second movable door 6. The connecting rod 86 of the second movable door 6 and the fixed door 4, in conjunction with the corresponding guide wheel 87, hooks the first movable door 5, thus constraining the width direction of the bottom of the first movable door 5 during its movement. While being constrained, it also plays a guiding role, thereby enabling the first movable door 5 to slide smoothly without wobbling during its movement.

[0083] Similarly, when the doorway is open, the second movable door 6, under the action of its connecting rod 86 and guide wheel 87, and in conjunction with the connecting rod 86 and guide wheel 87 of the first movable door 5, moves smoothly. When the first movable door 5 and the second movable door 6 overlap, they move smoothly simultaneously. This achieves the effect of smooth movement of the linkage door during opening and closing without shaking.

[0084] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
