In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0045] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.

[0046] Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of a suspension door 100 according to an embodiment of the present utility model. The embodiment of the present utility model provides a suspension door 100 for managing the entry and exit of pedestrians, vehicles, etc. at the channel entrance and exit.

[0047] Please also refer to Figures 3 to 5 , Figure 3 which is Figure 2 a partial structural exploded view of the suspension door 100 shown in Figure 4 which is Figure 3 an enlarged view of part B in Figure 5 which is Figure 2 a partial structural cross-sectional view of the suspension door 100 shown in . The suspension door 100 includes a support mechanism 10, a door body 20 and a corner support assembly 30. The door body 20 is slidably connected to the support mechanism 10. The door body 20 includes two cross beams 21 and a plurality of columns 22. The two cross beams 21 are arranged at intervals up and down, and the plurality of columns 22 are arranged at intervals left and right. Both ends of each column 22 are respectively connected to the two cross beams 21. The corner support assembly 30 includes a corner support member 31 and a fastening structure 32. The corner support member 31 is arranged at the corner where the cross beam 21 and the column 22 are connected. The corner support member 31 supports the cross beam 21 and the column 22, and the fastening structure 32 fixes the corner support member 31 at the corner where the cross beam 21 and the column 22 are connected.

[0048] Specifically, the support mechanism 10 is installed on the ground, and the door body 20 can slide relative to the support mechanism 10 along the first direction to the closed door position blocking the passage. At this time, the floating door 100 prevents pedestrians and vehicles from passing through. The door body 20 can also slide relative to the support mechanism 10 along the second direction to the open door position giving way to the passage. At this time, the floating door 100 allows pedestrians and vehicles to pass through. The first direction and the second direction are opposite. Figure 2 In the orientation shown, the first direction is to the left and the second direction is to the right. Of course, in actual installation applications, the installation direction of the suspension door 100 can also be different from the first direction. Figure 2 The opposite is shown, that is, the first direction is to the right and the second direction is to the left.

[0049] In the embodiment of the utility model, by setting the corner support 31 at the corner where the cross beam 21 and the column 22 are connected, the corner support 31 supports the cross beam 21 and the column 22 at the corner, so that the angle between the cross beam 21 and the column 22 can be kept stable, and the corner support 31 can resist the force deformation between the corner where the cross beam 21 and the column 22 are connected, thereby ensuring the stable connection between the cross beam 21 and the column 22, and improving the structural stability and bending resistance of the door body 20. In this way, when the door body 20 is suspended and slides in the air, the suspended part of the door body 20 can be prevented from sagging and deforming under the action of its own gravity, so that the door body 20 has better suspension ability and smoother sliding.

[0050] In addition, if Figure 1 As shown, in the conventional floating door 100a, the four corners where the two cross beams 21a and the two adjacent columns 22a are connected are fixed and supported by two inclined rods 30a arranged in an X shape, wherein the two ends of one inclined rod 30a are respectively connected to the two diagonals, and the two ends of the other inclined rod 30a are respectively connected to the other two diagonals, so that the visual effect of the inclined rod 30a on the door body 20a is more obvious; Figure 2 As shown, in the embodiment of the utility model, the corner support assembly 30 is only arranged at the corner where the cross beam 21 and the column 22 are connected. The corner support assembly 30 occupies a smaller proportion in the overall design of the floating door 100, and has less impact on the visual effect of the floating door 100, making the appearance of the floating door 100 more simple and beautiful.

[0051] like Figure 2 As shown, in some embodiments, the support mechanism 10 includes a first support pulley 11 and a second support pulley 12, and the first support pulley 11 and the second support pulley 12 are respectively arranged at the bottom of the door body 20, and the first support pulley 11 and the second support pulley 12 are respectively slidably connected to the door body 20.

[0052] When the door body 20 is in the closed position blocking the passage, the left end of the door body 20 is farther from the first support pulley 11 and the second support pulley 12 than its right end, and the left end of the door body 20 is in a suspended state. At this time, the first support pulley 11 acts as a fulcrum to support the door body 20, and the second support pulley 12 is closer to the right end of the door body 20 than the first support pulley 11 and presses down on the door body 20 to prevent the left end of the door body 20 from sagging and the right end from tilting up.

[0053] When the door body 20 is in the open position allowing passage, the right end of the door body 20 is farther from the first support pulley 11 and the second support pulley 12 than its left end, and the right end of the door body 20 is in a suspended state. At this time, the second support pulley 12 acts as a fulcrum to support the door body 20, and the first support pulley 11 is closer to the left end of the door body 20 than the second support pulley 12 and presses down on the door body 20 to prevent the left end of the door body 20 from tilting up and the right end from sagging.

[0054] In the specific implementation process, the first support pulley 11 and the second support pulley 12 are arranged at intervals along the opening / closing direction of the door body 20, and are respectively installed on the ground, and the first support pulley 11 and the second support pulley 12 are located on the same side of the passage.

[0055] In some embodiments, the two cross beams 21 are parallel to each other, and each column 22 is perpendicular to the two cross beams 21.

[0056] In the specific implementation process, one of the two cross beams 21 serves as the top beam of the door body 20, and the other of the two cross beams 21 serves as the bottom beam of the door body 20. The structures of the top beam and the bottom beam can be set according to actual needs. For example, to install a tail pull rod for adjusting the tension of the door body 20, the bottom beam can be extended by a certain length compared to the top beam to reserve an installation position for the tail pull rod; or for example, to enable the bottom of the door body 20 to be slidably connected to the support mechanism 10, the bottom beam can be reserved with a chute for accommodating the first support pulley 11 and the second support pulley 12 to slidably cooperate with the first support pulley 11 and the second support pulley 12.

[0057] Among them, each cross beam 21 can be spliced by multiple beam structures or can be integrally formed.

[0058] It can be understood that the number of the vertical columns 22 can be selected according to actual needs. When there is no need to install the door row unit, a larger number of vertical columns 22 can be selected and arranged between the two cross beams 21, so as to reduce the distance between every two adjacent vertical columns 22 and block the space between the two cross beams 21, thereby preventing people from passing through the door body 20; when it is necessary to install the door row unit, a smaller number of vertical columns 22 can be selected and arranged between the two cross beams 21, so as to reserve a distance for installing the door row unit between every two adjacent vertical columns 22. The door row unit and the vertical columns 22 jointly block the space between the two cross beams 21, thereby preventing people from passing through the door body 20.

[0059] As Figure 4 and Figure 5 shown, in some embodiments, the corner support 31 includes a connection structure 311 and a support structure 312. The connection structure 311 includes a first connection portion 3111 and a second connection portion 3112. The first connection portion 3111 is connected to the cross beam 21, the second connection portion 3112 is connected to the vertical column 22, and the support structure 312 is connected to the first connection portion 3111 and the second connection portion 3112. The support structure 312 supports the first connection portion 3111 and the second connection portion 3112.

[0060] In this embodiment, by connecting the first connection portion 3111 and the second connection portion 3112 of the corner support 31 to the cross beam 21 and the vertical column 22 respectively, the connection strength between the cross beam 21 and the vertical column 22 can be improved, and the stable connection between the cross beam 21 and the vertical column 22 can be ensured. Then, through the support structure 312 to support the first connection portion 3111 and the second connection portion 3112, the first connection portion 3111 and the second connection portion 3112 can be kept stable when the force is applied at the corner where the cross beam 21 and the vertical column 22 are connected, so as to realize the support of the corner support 31 for the cross beam 21 and the vertical column 22.

[0061] In some embodiments, both the first connection portion 3111 and the second connection portion 3112 are plate-shaped, and the first connection portion 3111 and the second connection portion 3112 form an L-shaped angle plate. In this way, the connection structure 311 in the shape of an L-shaped angle plate can be adapted to the corner where the cross beam 21 and the vertical column 22 are connected, so that the connection structure 311 can fit on the corner where the cross beam 21 and the vertical column 22 are connected. Moreover, the plate-shaped first connection portion 3111 and the second connection portion 3112 can respectively perform surface-to-surface abutment and contact with the cross beam 21 and the vertical column 22, ensuring the force-bearing area of the connection structure 311 at the corner where the cross beam 21 and the vertical column 22 are connected, so as to better provide a supporting effect for the cross beam 21 and the vertical column 22 and avoid the concentrated force effect on the connection structure 311 from affecting the supporting effect of the cross beam 21 and the vertical column 22.

[0062] The support structure 312 is in the shape of a plate. Two adjacent sides of the support structure 312 are fixedly connected to the first connection portion 3111 and the second connection portion 3112 respectively. In this way, the support structure 312 can support the first connection portion 3111 and the second connection portion 3112 along its two sides, so as to better provide a supporting effect for the first connection portion 3111 and the second connection portion 3112, making it not easy for the support structure 312 to bend and deform between the first connection portion 3111 and the second connection side portion, and can better resist the force deformation of the first connection portion 3111 and the second connection portion 3112, ensuring the supporting effect of the corner support 31 between the cross beam 21 and the column 22.

[0063] Specifically, the maximum surface plane of the first connection portion 3111 and the maximum surface plane of the second connection portion 3112 are perpendicular to each other. The maximum surface plane of the support structure 312 is perpendicular to the maximum surface plane of the first connection portion 3111 and the maximum surface plane of the second connection portion 3112. The support structure 312 has two adjacent perpendicular sides, and the two adjacent perpendicular sides of the support structure 312 are respectively connected to the maximum surface plane of the first connection portion 3111 and the maximum surface plane of the second connection portion 3112.

[0064] Please refer to Figure 6 , Figure 6 is Figure 4 the exploded view of the structure of the corner support 31 shown. In some embodiments, the first connection portion 3111 and the second connection portion 3112 are both provided with sockets 3101, and two adjacent sides of the support structure 312 are both provided with protrusions 3121. The protrusions 3121 on the two adjacent sides of the support structure 312 are respectively inserted into the sockets 3101 on the first connection portion 3111 and the second connection portion 3112 and fixed.

[0065] In this embodiment, by providing the socket 3101 on the connection structure 311 and the protrusion 3121 corresponding to the socket 3101 on the support structure 312, on the one hand, the socket 3101 can play a positioning role for the protrusion 3121, which is convenient for the assembly and fixation between the support structure 312 and the connection structure 311; on the other hand, the socket 3101 plays a limiting role for the protrusion 3121, which can limit the movement of the support structure 312 relative to the connection structure 311 along the plane parallel to the maximum surface plane of the first connection portion 3111 or the maximum surface plane of the second connection portion 3112, improving the anti-shear ability of the connection structure 311 and the support structure 312, and strengthening the connection between the connection structure 311 and the support structure 312.

[0066] In the specific implementation process, the support structure 312 can be fixed to the first connecting portion 3111 and the second connecting portion 3112 by welding. Specifically, the protrusions 3121 on two adjacent vertical sides of the support structure 312 are respectively inserted into the sockets 3101 on the first connecting portion 3111 and the second connecting portion 3112. After the two adjacent vertical sides of the support structure 312 are respectively attached to the surfaces of the first connecting portion 3111 and the second connecting portion 3112, the joints between the support structure 312 and the first connecting portion 3111 and the second connecting portion 3112 can be welded and fixed along the length directions of the two adjacent vertical sides of the support structure 312, so that the support structure 312 is fixed between the first connecting portion 3111 and the second connecting portion 3112.

[0067] Please refer to Figure 7 , Figure 7 FIG. Figure 7 is a three-dimensional structural view of the corner support 31 according to another embodiment of the present invention. In some embodiments, the first connecting portion 3111 and the second connecting portion 3112 are respectively formed by bending from two adjacent edges of the support structure 312. That is, the corner support 31 is an integral structure. Thus, the first connecting portion 3111 and the second connecting portion 3112 do not need to be assembled and fixed to the support structure 312, which simplifies the production steps of the corner support 31 and reduces the production cost of the corner support 31.

[0068] Specifically, the first connecting portion 3111 and the second connecting portion 3112 are respectively formed by bending 90 degrees from two adjacent vertical edges of the support structure 312 toward the same side of the support structure 312.

[0069] In some other embodiments, the corner support 31 can also be of other structural shapes, and is not limited to the combination of the first connecting portion 3111, the second connecting portion 3112 and the support structure 312 that are all in the shape of plates. For example, the first connecting portion 3111, the second connecting portion 3112 and the support structure 312 are all in the shape of rods, and the first connecting portion 3111, the second connecting portion 3112 and the support structure 312 are connected end to end to form a tripod.

[0070] Such as Figure 5As shown in the figure, if corner support assemblies 30 are provided on both the left and right sides of the column 22, during the assembly process, to facilitate the fixation of the corner support assemblies 30, two corner support members 31 need to be fixed to the cross beam 21 respectively, and then the column 22 is inserted between the two corner support members 31 and fixed to the cross beam 21. Among them, even if the reserved distance between the second connecting portions 3112 of the two corner support members 31 just fits the width of the column 22, interference is still likely to occur between the column 22 and the second connecting portions 3112 during the insertion process, making it inconvenient for the column 22 to be inserted; if the reserved distance between the second connecting portions 3112 of the two corner support members 31 is too large, after the column 22 is inserted, a certain gap will be generated between the column 22 and the second connecting portions 3112, affecting the connection between the second connecting portions 3112 and the column 22.

[0071] Therefore, in some embodiments, a bending portion 3113 is provided at the end of the second connecting portion 3112 far from the first connecting portion 3111. The bending portion 3113 bends from the end of the second connecting portion 3112 toward the side where the first connecting portion 3111 is located. The bending portion 3113 is used to guide the column 22 during assembly, avoid assembly interference of the corner support member 31 with the column 22 during assembly, and facilitate the insertion of the column 22 between the second connecting portions 3112 of the two corner support members 31. When the column 22 is inserted between the two second connecting portions 3112, the column 22 can push open the ends of the two second connecting portions 3112 far from the first connecting portion 3111 through the two bending portions 3113, thus facilitating the insertion of the column 22.

[0072] Among them, the bending portion 3113 can be in the shape of an arc-shaped plate relative to the second connecting portion 3112, or can be in the shape of an inclined straight plate relative to the second connecting portion 3112.

[0073] Such as Figure 3 and Figure 4 As shown in the figure, in some embodiments, the door body 20 further includes a door row unit 23. A door row unit 23 is provided between every two adjacent columns 22. The door row unit 23 is connected to the cross beam 21. The door row unit 23 is provided with an avoidance groove 231, and the support structure 312 is inserted into the avoidance groove 231.

[0074] In this embodiment, by providing the avoidance groove 231 on the door row unit 23, after the door body 20 is assembled, the support structure 312 is located in the avoidance groove 231, which can avoid assembly interference between the door row unit 23 and the corner support members 31 on the columns 22 at its left and right ends. The avoidance groove 231 allows the left and right ends of the door row unit 23 to be arranged closer to the corresponding columns 22, and there is no need to increase the gap between the door row unit 23 and the corresponding columns 22 to avoid the support structure 312, making the structure of the door body 20 more compact.

[0075] In some embodiments, the door row unit 23 includes a fixed frame and a plurality of blocking rods. The fixed frame is in the shape of a rectangular frame. The upper and lower sides of the fixed frame are respectively connected to two cross beams 21, and / or the left and right sides of the fixed frame are respectively connected to two adjacent columns 22. The plurality of blocking rods are arranged at intervals along the length direction of the fixed frame. The two ends of each blocking rod are respectively connected to the upper and lower sides of the fixed frame, and the blocking rod is perpendicular to the upper and lower sides of the fixed frame.

[0076] In some other embodiments, the door row unit 23 may also be other structures, not limited to the above-mentioned structure of the fixed frame and the blocking rods. For example, the door row unit 23 includes a fixed frame and a sealing plate; the fixed frame is in the shape of a rectangular frame. The upper and lower sides of the fixed frame are respectively connected to two cross beams 21, and / or the left and right sides of the fixed frame are respectively connected to two adjacent columns 22; the sealing plate is sealed at the middle opening of the fixed frame, and the four sides of the sealing plate are respectively connected to the four sides of the fixed frame. Of course, in some other embodiments, the above-mentioned fixed frame can also be omitted. A plurality of blocking rods are arranged between every two adjacent columns 22 at intervals along the length direction of the cross beam 21 to form the door row unit 23.
