[0005] The technical scheme has at least the following beneficial effects: when the sliding door is installed in the opening of the building outer wall, the lower rail is installed on the ground where the opening is located, and the plurality of door panels are expanded in the opening in the transverse direction to close the opening; when the opening needs to be opened, the movable device drives the door panel arranged at the first side to move towards the door panel arranged at the last side, the door panel slides on the lower rail by the lower sliding member at the bottom side of the door panel, the door panel at the last side first passes the adjusting member, the lower connecting shaft at the bottom side of the door panel is driven to rotate by the adjusting member when passing the adjusting member, so that the door panel is rotated from the transverse state to the longitudinal state, and the connecting rod mechanism between the two door panels is switched from the expanded state to the folded state as the next door panel passes the adjusting member, so that the plurality of door panels are rotated and adjusted in sequence by the adjusting member to be rotated to the longitudinal state; when all the door panels are completely opened, the door panels are stacked in the longitudinal direction, the transverse space of the opening is effectively reduced, and the opening of the opening is increased; when the opening needs to be closed, the movable device drives the door panel arranged at the first side to move, the door panel first passes the adjusting member, the lower connecting shaft at the bottom side of the door panel is driven to reverse by the adjusting member when passing the adjusting member, so that the door panel is rotated from the longitudinal state to the transverse state, the connecting rod mechanism between the door panel connected at the first side and the door panel connected at the rear side is gradually expanded, and then the power is transmitted backward through the connecting rod mechanism to drive the door panel at the rear side to pass the adjusting member in sequence, so that the plurality of door panels are rotated and opened in sequence, so that the door panels are rotated to the transverse or longitudinal state during the movement of the door panels, so that the opening of the building opening is closed and opened, the plurality of door panels arranged in the longitudinal direction are arranged in the transverse direction in the opening, the transverse space of the opening is effectively reduced, and the overall practicability is improved.
[0006] As a further improvement of the above technical scheme, the upper rail is arranged above the plurality of door panels, the top end of the plurality of upper connecting shafts is rotatably connected with an upper sliding member, and the plurality of upper sliding members are slidably connected with the upper rail. The upper rail is installed at the top side of the opening, and the door panel is slidably connected with the upper rail through the upper sliding member at the top side during movement, so that the stability of the movement of the door panel is improved, and the condition that the top side of the door panel is easily shaken is effectively prevented.
[0007] As a further improvement of the above technical scheme, the plurality of upper connecting shafts are connected with a limiting block, the bottom side of the upper rail is provided with a limiting groove extending along the length direction of the upper rail, and the limiting block can enter the limiting groove when the door panel is rotated to be parallel to the upper rail. When the door panel is closed, the door panel is rotated to the transverse state, at this time, the limiting block at the top side of the door panel is rotated to the limiting groove at the bottom side of the upper rail, and the limiting block can be driven to enter the limiting groove as the door panel continues to move, so that the door panel is prevented from rotating by the cooperation of the two, the position state of the door panel in the transverse direction is stabilized, and the structural stability is improved.
[0008] As a further improvement of the above technical solution, the end portion of the limiting block close to the limiting groove gradually narrows in the direction close to the limiting groove.

The drive motor is connected to the sliding frame. The drive motor drives the drive gear. The drive gear is in mesh with the upper rack. When it is necessary to move the door panel, the drive motor works to drive the drive gear to rotate. Since the drive gear is in mesh with the upper rack, the sliding frame can slide on the fixed frame along the length direction of the upper rack, thereby moving the door panel. Thus, by using the drive motor to drive the drive gear to rotate forward or reverse, the sliding frame can move back and forth on the fixed frame, thereby providing power for opening or closing the door panel.
[0010] As a further improvement of the above technical solution, a machine shell is arranged between one end of the upper rail and one end of the lower rail.

The machine frame, the upper rail and the lower rail form a stable frame structure, thereby improving the structural stability of the upper rail and the lower rail. When the plurality of door panels are rotated to the longitudinal direction and are stored, they can enter the slot on one side of the machine shell. Thus, the plurality of door panels can be stored when the opening is opened, thereby better protecting the plurality of door panels and improving the overall appearance.
[0011] As a further improvement of the above technical solution, a stand is arranged between the other end of the upper rail and the other end of the lower rail. During installation, the machine shell can be installed on the other side of the opening. The stand forms a stable support structure between the other end of the upper rail and the one end of the lower rail, thereby further improving the structural stability of the upper rail and the lower rail.
[0012] As a further improvement of the above technical solution, the adjusting member comprises a lower rack arranged beside the lower rail. A plurality of lower connecting shafts are synchronously connected with a plurality of transmission gears. When the lower connecting shafts pass through the lower rack, the transmission gears are in mesh with the lower rack. When the door panel moves to pass through the lower rack, the transmission gears on the bottom side of the door panel pass through the lower rack. At this time, the transmission gears are in mesh with the lower rack, thereby driving the door panel to rotate through the lower connecting shafts, thereby achieving adjustment of the longitudinal or transverse state.
[0013] As a further improvement of the above technical solution, the connecting rod mechanism comprises a first connecting rod and a second connecting rod which are rotationally connected to each other, one end of the first connecting rod rotationally connected to one of the upper connecting shafts away from the second connecting rod, and one end of the second connecting rod rotationally connected to the other upper connecting shaft away from the first connecting rod. When the door panels close the opening, the two door panels are away from each other, at this time, the first connecting rod and the second connecting rod connected between the two door panels are in an unfolded state, so that the door panels can be opened one by one and power transmission is provided when the next door panel is pulled out; when the opening is opened, the plurality of door panels are arranged longitudinally, at this time, the first connecting rod and the second connecting rod are in a folded state, which can reduce the occupation of space, so that the plurality of door panels are arranged more closely when closing the opening.

DETAILED DESCRIPTION
[0021] The concept, specific structure and generated technical effects of the present application will be described clearly and completely in combination with the embodiments and drawings, so as to fully understand the purpose, features and effects of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments, and other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative labor are within the protection scope of the present application. In addition, all the connection relationships mentioned in the text do not mean that the components are directly connected, but that a more optimal connection structure can be composed by adding or reducing connecting accessories according to the specific implementation. The technical features in the present application can be combined interactively without conflict.
[0022] Referring to Figures 1 to 3 A sliding door comprises a lower rail 1, a door assembly comprising a plurality of door panels 21 arranged along the length direction of the lower rail 1, upper connecting shafts 211 respectively connected to the middle part of the top side of the plurality of door panels 21, connecting rod mechanisms 212 arranged between adjacent two upper connecting shafts 211, lower connecting shafts respectively connected to the middle part of the bottom side of the plurality of door panels 21, lower sliding members 213 respectively rotatably connected to the bottom end of the plurality of lower connecting shafts, and the plurality of lower sliding members 213 respectively slidably connected to the lower rail 1, an adjusting member located beside the lower rail 1, the adjusting member capable of driving the plurality of lower connecting shafts to rotate forward or reversely when the plurality of lower connecting shafts respectively pass through the adjusting member, and a movable device having a driving end reciprocally movable along the length direction of the lower rail 1, the driving end drivingly connected to the door panel 21 arranged at the first side.
[0023] When the sliding door is installed in the opening of the building outer wall, the lower rail 1 is installed on the ground where the opening is located, and a plurality of door panels 21 are arranged in the opening and expanded in the transverse direction to close the opening. When the opening needs to be opened, the movable device drives the door panel 21 arranged at the front side to move to the door panel 21 arranged at the rear side, and the door panel 21 slides on the lower rail 1 by relying on the lower sliding piece 213 at the bottom side of the door panel 21. The door panel 21 at the rear side first passes through the adjusting piece, and the lower connecting shaft at the bottom side of the door panel 21 is driven to rotate by the adjusting piece when passing through the adjusting piece, so that the door panel 21 is rotated from the transverse state to the longitudinal state. As the next door panel 21 passes through the adjusting piece, the connecting rod mechanism 212 between the two door panels 21 is switched from the expanded state to the folded state. In this way, a plurality of door panels 21 are sequentially rotated and adjusted by the adjusting piece and can be rotated to the longitudinal state. When all the door panels 21 are completely opened, all the door panels 21 are stacked in the longitudinal direction, effectively reducing the occupation of the transverse space of the opening and increasing the opening of the opening. When the opening needs to be closed, the movable device drives the door panel 21 arranged at the front side to move, and the door panel 21 first passes through the adjusting piece, and the lower connecting shaft at the bottom side of the door panel 21 is driven to reverse by the adjusting piece when passing through the adjusting piece, so that the door panel 21 is rotated from the longitudinal state to the transverse state. The connecting rod mechanism 212 between the door panel 21 at the front side and the door panel 21 at the rear side is gradually expanded, and then the power is transmitted backward through the connecting rod mechanism 212 to drive the door panel 21 at the rear side to sequentially pass through the adjusting piece, so that a plurality of door panels 21 are sequentially rotated and opened. In this way, the door panel 21 is rotated to the transverse or longitudinal state during the movement of the door panel 21, so as to realize the closing and opening of the building opening. By arranging a plurality of door panels 21 in the longitudinal direction in the opening in the transverse direction, the occupation of the transverse space of the opening is effectively reduced, and the overall practicability is improved.
[0024] In order to improve the stability of the movement of the door panel 21, in the embodiment, the upper rail 3 is arranged above the plurality of door panels 21, the top end of the plurality of upper connecting shafts 211 is rotatably connected with the upper sliding piece 214, and the plurality of upper sliding pieces 214 is slidably connected with the upper rail 3. The upper rail 3 is installed at the top side of the opening. When the door panel 21 moves, the upper sliding piece 214 at the top side of the door panel 21 is slidably connected with the upper rail 3, so as to improve the stability of the movement of the door panel 21 and effectively prevent the top position of the door panel 21 from shaking.
[0025] In order to ensure that the door plate 21 can be kept in a stable horizontal state when closing the opening, in the embodiment, the plurality of upper connecting shafts 211 are respectively connected with limiting blocks 215, the bottom side of the upper rail 3 is provided with limiting grooves 31 extending along the length direction of the upper rail 3, and when the door plate 21 is rotated to be parallel to the upper rail 3, the limiting blocks 215 can enter the limiting grooves 31. When the door plate 21 is closing the opening, the door plate 21 is rotated to a horizontal state, at this time, the limiting blocks 215 on the top side of the door plate 21 are rotated to correspond to the limiting grooves 31 on the bottom side of the upper rail 3, and as the door plate 21 continues to move, the limiting blocks 215 can be driven to enter the limiting grooves 31, and by the cooperation of the two, the rotation of the door plate 21 can be prevented, so as to stabilize the horizontal position of the door plate 21 and improve the structural stability.
[0026] When the limiting blocks 215 enter the limiting grooves 31, the two sides of the limiting blocks 215 along the width direction abut against the two sides of the limiting grooves 31, so as to stabilize the position state, in order to make the limiting blocks 215 more easily enter the limiting grooves 31, in the embodiment, the width of the end of the limiting blocks 215 close to the limiting grooves 31 gradually decreases in the direction close to the limiting grooves 31. The gradually decreasing end of the limiting blocks 215 can make the limiting blocks 215 more easily enter the limiting grooves 31, which is beneficial to ensure that the limiting blocks 215 and the limiting grooves 31 can be accurately aligned and improve the stability of the overall operation.
[0027] The moving device is mainly used to provide a driving force for the door plate 21 to move reciprocatingly along a straight line, in order to ensure that sufficient driving force is provided for the door plate 21, in the embodiment, the moving device comprises a fixed frame 41, an upper rack 42, a sliding frame 43, a driving motor 44 and a driving gear 45, the upper rack 42 is connected to the fixed frame 41, the sliding frame 43 is slidingly connected to the fixed frame 41 along the length direction of the upper rail 3, the sliding frame 43 is the driving end, the driving motor 44 is connected to the sliding frame 43, the driving motor 44 drives the driving gear 45 to be connected, and the driving gear 45 is engaged with the upper rack 42. When it is needed to drive the door plate 21 to move, the driving motor 44 works to drive the driving gear 45 to rotate, and as the driving gear 45 is engaged with the upper rack 42, the sliding frame 43 can slide on the fixed frame 41 along the length direction of the upper rack 42, so as to drive the door plate 21 to move, and thus by using the driving motor 44 to drive the driving gear 45 to rotate forward or reverse, the sliding frame 43 can be realized to move reciprocatingly on the fixed frame 41, and the door plate 21 can be provided with the power to open or close.
[0028] In some embodiments, a machine shell 5 is arranged between one end of the upper rail 3 and one end of the lower rail 1, and one side of the machine shell 5 is provided with a slot capable of accommodating a plurality of door panels 21. When installed, the machine shell 5 can be installed on one side of the opening, and the frame, the upper rail 3, and the lower rail 1 form a stable frame structure, improving the structural stability of the upper rail 3 and the lower rail 1. When a plurality of door panels 21 are rotated to a longitudinal direction and are stored, they can be placed in the slot on one side of the machine shell 5. In this way, the plurality of door panels 21 can be stored when the opening is opened, better protecting the plurality of door panels 21 and improving the overall appearance.
[0029] Further, a stand 6 is arranged between the other end of the upper rail 3 and the other end of the lower rail 1. When installed, the machine shell 5 can be installed on the other side of the opening, and the stand 6 forms a stable support structure between the other end of the upper rail 3 and one end of the lower rail 1, further improving the structural stability of the upper rail 3 and the lower rail 1. In actual application, when only the upper rail 3 and the lower rail 1 are present, the entire device needs to be installed in the opening of a building. When the machine shell 5 and the stand 6 are also present to provide support on both sides of the upper rail 3 and the lower rail 1, the entire device can be applied to an outdoor environment.
[0030] As a specific structural embodiment of the adjusting member, the adjusting member includes a lower rack 71 arranged at the side of the lower rail 1, and a plurality of lower connecting shafts are respectively and synchronously connected with transmission gears 72. When the lower connecting shafts pass through the lower rack 71, the transmission gears 72 and the lower rack 71 are mutually engaged. When the door panel 21 moves through the lower rack 71, the transmission gear 72 at the bottom side of the door panel 21 passes through the lower rack 71, at which time the transmission gear 72 and the lower rack 71 are mutually engaged, thereby rotating the door panel 21 through the lower connecting shaft, achieving adjustment of the longitudinal or transverse state.
[0031] As a specific embodiment of the connecting rod mechanism 212, the connecting rod mechanism 212 includes a first connecting rod and a second connecting rod that are rotationally connected to each other, one end of the first connecting rod away from the second connecting rod is rotationally connected to one of the upper connecting shafts 211, and one end of the second connecting rod away from the first connecting rod is rotationally connected to another of the upper connecting shafts 211. When the door panels 21 close the opening, the two door panels 21 are in a mutually distant state, at which time the first connecting rod and the second connecting rod connected between the two door panels 21 are in an unfolded state, thereby achieving opening of the door panels 21 one by one and providing power transmission when the next door panel 21 is pulled out. When the opening is opened, the plurality of door panels 21 are arranged in a longitudinal direction, at which time the first connecting rod and the second connecting rod are in a folded state, thereby reducing the occupation of space and allowing the plurality of door panels 21 to be arranged more closely when closing the opening.
[0032] A door access system includes the sliding door described above.
[0033] In the access control system, the above translation door is used to open or close the opening in the building, and the door plate 21 can be adjusted in rotation in the transverse or longitudinal state during the movement of the door plate 21. When the building opening is closed, the multiple longitudinally arranged door plates 21 are arranged transversely in the opening, which effectively reduces the transverse space occupied by the opening and improves the overall practicability.
[0034] The above describes the preferred embodiments of the present application, but the present application is not limited to the above-mentioned embodiments.
