Abstract
Description
Technical Field
[0001] This utility model relates to the field of door equipment technology, and in particular to a limiting mechanism and an electric door. Background Technology
[0002] Electric gates are a common type of gate installed at the entrances of various residential communities, businesses, factories, and other places to control the entry and exit of pedestrians and vehicles.
[0003] like Figure 1 As shown, in order to ensure that the door 01 runs in the preset direction, a track 02 is laid on the road surface that the door 01 passes through. The door 01 and the track 02 are guided and matched. The track 02 is used to guide the door 01 to run along the length direction X of the track 02 (that is, the preset direction).
[0004] In the related technology, the bottom of the door body 01 is connected to a hook structure 011, and the track 02 is provided with a limiting groove 021. The hook structure 011 extends into the limiting groove 021 and cooperates with the limiting groove 021 for limiting. When the door body 01 tends to derail or overturn under the action of external force, the upper wall 0211 of the limiting groove 021 can abut against the hook structure 021 and limit the door body 01 from derailing or overturning.
[0005] However, the hook structure 011 and the door body 01 are fixed relative to each other, and the hook structure 011 cannot move relative to the door body 01. If the road surface where the track 02 is located is uneven, causing the track 02 to be uneven, then during the process of the door body 01 driving the hook structure 011 to slide along the limiting groove 021, the hook structure 011 may be blocked by the upper wall 0211 or the bottom wall 0212 of the limiting groove 021, which will cause the hook structure 011 to be unable to continue sliding, and thus cause the door body 01 to get stuck on the track 02. Utility Model Content
[0006] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a limiting mechanism and an electric door, which can prevent the door from getting stuck on the track during its sliding motion.
[0007] In a first aspect, this utility model embodiment provides a limiting mechanism for connecting a door body and a track, wherein the track is provided with a limiting groove, and the limiting mechanism includes: Adapter, used for connection to the door body; Activity components, connected to the adapter activity; The limiting component is used to slide with the rail. The limiting component is movably connected to the adapter through the movable component. The limiting component can rise and fall relative to the adapter. The limiting component is used to extend into the limiting groove and cooperate with the limiting groove to limit the limiting mechanism from disengaging from the rail.
[0008] Optionally, the movable component includes a connecting rod, one end of which is rotatably connected to the adapter, and the other end of which is rotatably connected to the limiting component.
[0009] Optionally, the active component may also include a first bearing and a second bearing; The first bearing includes a first inner ring and a first outer ring. The first outer ring is sleeved on the outside of the first inner ring. The first inner ring is used to connect with the adapter. The first outer ring is connected to one end of the connecting rod. The second bearing includes a second inner ring and a second outer ring. The second outer ring is sleeved on the outside of the second inner ring. The second inner ring is connected to the limiting component, and the second outer ring is connected to the other end of the connecting rod.
[0010] Optionally, the outer sidewall of the first inner ring and the inner sidewall of the first outer ring cooperate to form a first spherical pair; The outer wall of the second inner ring and the inner wall of the second outer ring cooperate to form the second spherical pair.
[0011] Optionally, the active component includes a flexible connector, one end of which is connected to the adapter and the other end of which is connected to the limiting component.
[0012] Optionally, the active component further includes a first connecting ring and a second connecting ring. The first connecting ring is connected to one end of the flexible connector and is rotatably connected to the adapter. The second connecting ring is connected to the other end of the flexible connector and is rotatably connected to the limiting component.
[0013] Optionally, the track is provided with two limiting grooves and two limiting parts. The two limiting grooves are located on both sides of the track in the width direction, and the two limiting parts are located on the upper side of the two limiting grooves respectively. The limiting assembly includes a base and at least two first limiting members, which are respectively connected to the base and are respectively used to extend into two limiting grooves. The first limiting members and the corresponding limiting parts are opposite to each other along the height direction of the track.
[0014] Optionally, the limiting assembly further includes at least two second limiting members, which are respectively connected to the base body. The at least two second limiting members are respectively used to be disposed on opposite sides or opposite sides of the two limiting portions along the width direction of the track, and the second limiting members are opposite to the limiting portions along the width direction of the track.
[0015] Optionally, the limiting component further includes at least one third limiting member, which is connected to the base body and is disposed on the upper side of the limiting portion and abuts against the limiting portion.
[0016] Secondly, this utility model embodiment also provides an electric door, which includes a door body, a track, and a limiting mechanism as described above, wherein the limiting mechanism is connected to the door body and the track respectively.
[0017] Compared with the prior art, the limiting component of the limiting mechanism of this utility model is movably connected to the adapter through a movable component. The movable component provides the limiting component with the freedom to rise and fall relative to the adapter. Thus, even if the track is uneven, or even if the height difference between the track and the ground exceeds the height of the limiting groove, the limiting component can still rise or fall relative to the adapter as the door slides along the track via the movable component. This adjusts the horizontal height of the limiting component, preventing it from being blocked by the upper or lower wall of the limiting groove and thus preventing it from continuing to slide. This allows the limiting component to slide smoothly along the length of the track, preventing the door from getting stuck on the track during sliding and ensuring the normal operation of the door. Furthermore, it achieves adaptability to different height positions of the track during the sliding process of the limiting component, reducing the flatness requirements of the track surface and improving the adaptability of the limiting mechanism to different road surface environments.
[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation
[0022] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on the other element, or one or more intermediate elements can exist between them. The terms "upper," "lower," "left," "right," "upper end," "lower end," "top," and "bottom," etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0023] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.
[0024] like Figure 1 As shown, in the related technology, a limiting structure 022 is provided on the track 02. The limiting structure 022 is I-shaped and extends along the length direction X of the track 02. Limiting grooves 021 are respectively provided on both sides of the limiting structure 022 along the width direction Y of the track 02. The openings of the limiting grooves 021 on both sides are set opposite to each other. The limiting groove 021 has an upper wall 0211, a bottom wall 0212, and a side wall 0213, with the side wall 0213 located between the upper wall 0211 and the bottom wall 0212. Two hook structures 011 are connected to the bottom of the door body 01. The two hook structures 011 extend to the limiting grooves 021 on both sides. When the door body 01 has a tendency to derail or overturn under the action of external force, the upper wall 0211 of the limiting groove 021 can abut against the hook structure 011 and prevent the hook structure 011 from leaving the track 02 along the height direction Z of the track 02. However, since the hook structure 011 and the door body 01 are fixed relative to each other, the hook structure 011 cannot move relative to the door body 01. If the road surface where the track 02 is located is uneven, causing the track 02 to be uneven, and the height difference of the ground where the track 02 is located exceeds the height of the limiting groove 021 (that is, the distance between the upper wall 0211 and the bottom wall 0212), it will greatly increase the risk that the hook structure 011 will be blocked by the upper wall 0211 or the bottom wall 0212 of the limiting groove 021 during the sliding process along the track 02, thereby causing the door body 01 to get stuck on the track 02.
[0025] The existing limiting structure 022 has different specific shapes and structures. In addition to the above-mentioned I-shaped limiting structure 022, the limiting structure 022 can also be in other shapes and structures, such as T-shaped. Since the hook structure 011 and the door body 01 are relatively fixed to each other, if the road surface where the track 02 is located is uneven, causing the track 02 to be uneven, there is a risk that the door body 01 will get stuck on the track 02 during the sliding of the hook structure 011 along the track 02.
[0026] In view of this, please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of an electric door 100 provided in one embodiment of the present invention. The present invention proposes a limiting mechanism 30 and an electric door 100. The limiting mechanism 30 is used to connect the door body 10 and the track 20. The limiting mechanism 30 can prevent the door body 10 from getting stuck on the track 20 during the sliding process along the track 20.
[0027] The electric gate 100 includes a gate body 10, a track 20, and a limiting mechanism 30. The gate body 10 can slide along a preset direction to block or clear a road. The track 20 is disposed below the gate body 10 along the preset direction, and the length direction X of the track 20 is parallel to the preset direction. The limiting mechanism 30 is used to connect the gate body 10 and the track 20. The gate body 10 is guided to the track 20 through the limiting mechanism 30, so that the sliding of the gate body 10 is along the length direction X of the track 20, that is, the sliding of the gate body 10 is along the aforementioned preset direction.
[0028] exist Figure 2 In the diagram, only the uprights 11, the bottom beam 12, and the traveling mechanism 13 of the gate body 10 are shown. It can be understood that the gate body 10 can be a sliding gate. The sliding gate also includes several gate rows. There is a gate row between every two adjacent uprights 11. Each gate row and each upright 11 is connected to the bottom beam 12. The gate body 10 can slide along a preset direction through the traveling mechanism 13 to block the road or make way for the road.
[0029] It is understood that this utility model does not limit the specific structure of the door body 10. In some other embodiments, the door body 10 may also be a telescopic door, the bottom beam 12 may be omitted, and the telescopic door may also include foldable door panels. A foldable door panel is provided between every two adjacent uprights 11. The door body 10 can slide along a preset direction through the walking mechanism 13 and extend each foldable door panel to block the road. The door body 10 can also slide along a preset direction through the walking mechanism 13 and retract each foldable door panel to make way for the road.
[0030] Please combine Figure 3 and Figure 9 , Figure 3 for Figure 1 The diagram shows a three-dimensional view of the limiting mechanism 30. The limiting mechanism 30 includes a connector 31, a movable component 32, and a limiting component 33. Figure 9 This is a side view of the structure where the limiting mechanism 30 cooperates with the track 20. The adapter 31 is used to connect to the door body 10. The movable component 32 is movably connected to the adapter 31. The limiting component 33 is used to slide with the track 20. The limiting component 33 is movably connected to the adapter 31 through the movable component 32. The limiting component 33 can rise and fall relative to the adapter 31. The track 20 is provided with a limiting groove 201. The limiting component 33 is used to extend into the limiting groove 201 of the track 20 and cooperate with the limiting groove 201 to limit the limiting mechanism 30 from disengaging from the track 20.
[0031] Specifically, when the door 10 is subjected to external force, causing the door 10 to tend to derail or overturn, the upper wall 2011 of the limiting groove 201 can abut against the limiting component 33 and restrict the limiting mechanism 30 from disengaging from the track 20 along the height direction Z of the track 20, thereby restricting the door 10 from derailing or overturning.
[0032] In this embodiment of the invention, the limiting component 33 is movably connected to the adapter 31 via the movable component 32. The movable component 32 provides the limiting component 33 with the freedom to rise and fall relative to the adapter 31. Thus, even if the track 20 is uneven, or even if the height difference between the track 20 and the ground exceeds the height of the limiting groove 201, the limiting component 33 can still rise or fall relative to the adapter 31 as the door 10 slides along the track 20 via the movable component 32, thereby adjusting the horizontal height of the limiting component 33 and preventing the limiting component 33 from being moved. 3. When the limiting component 33 is blocked by the upper wall 2011 or the bottom wall 2012 of the limiting groove 201, the limiting component 33 can slide smoothly along the length direction X of the track 20, preventing the door 10 from getting stuck on the track 20 during the sliding process, ensuring the normal operation of the door 10, and realizing the adaptability of the limiting component 33 to different height positions of the track 20 during the sliding process. This reduces the flatness requirements of the road surface where the track 20 is located for the limiting mechanism 30, and improves the adaptability of the limiting mechanism 30 to different road surface environments.
[0033] Furthermore, since the movable component 32 needs to have a certain degree of freedom of movement when connected to other components, the connection structure at its connection point will be relatively complex. In this embodiment of the utility model, by setting a connector 31 that is fixed to the door body 10, the structural modification required when connecting the door body 10 and the limiting mechanism 30 can be reduced, and the adaptability of the limiting mechanism 30 to different styles of door bodies 10 can be improved.
[0034] Specifically, please refer to Figure 4 and Figure 5 , Figure 4 for Figure 3 The diagram shows the first state of the limiting mechanism 30. Figure 5 for Figure 3 The second state diagram of the limiting mechanism 30 shown indicates that if the ground where the track 20 is located is uneven, causing the track 20 to be uneven, then during the process of the door body 10 driving the limiting component 33 to slide along the track 20 through the movable component 32, when the limiting component 33 passes through the lower position of the track 20, it can descend relative to the adapter 31 to pass through that position, and when the limiting component 33 passes through the higher position of the track 20, it can rise relative to the adapter 31 to pass through that position.
[0035] More specifically, with Figure 4 and Figure 5Taking the indicated orientation as an example, assume that the horizontal level of the middle section of track 20 is higher than that of the left and right sections of track 20, the ground where the left and right sections of track 20 are located is relatively concave, and the horizontal levels of the left and right sections of track 20 are the same, while the ground where the middle section of track 20 is located is relatively abrupt. Figure 4 As shown, during the process of the door 10 driving the limiting component 33 through the movable component 32 across the left section of the track 20, the limiting component 33 and the adapter 31 can maintain a basic first vertical distance H1. From Figure 4 Transfer to Figure 5 During the process of the door body 10 moving from the left section to the middle section of the track 20 via the movable component 32 driving the limiting component 33, due to the increased horizontal height of the track 20, the limiting component 33, which has the freedom to rise and fall, can rise relative to the adapter 31 under the pushing force of the bottom wall 2012 of the limiting groove 201, to prevent the limiting component 33 from being stuck against the bottom wall 2012 of the limiting groove 201; after the limiting component 33 enters the middle section of the track 20, the limiting component 33 and the adapter 31 can basically maintain a second vertical distance H2, wherein, since the horizontal height of the middle section of the track 20 is higher than the horizontal height of the left section of the track 20, the second vertical distance H2 is less than the first vertical distance H1. Figure 5 Transfer to Figure 4 During the process of the door body 10 driving the limiting component 33 from the middle section of the track 20 to the right section through the movable component 32, as the horizontal height of the track 20 decreases, the limiting component 33, which has the freedom to rise and fall, can descend relative to the adapter 31 under its own gravity to prevent the limiting component 33 from hitting the upper wall 2011 of the limiting groove 201. After the limiting component 33 enters the right section of the track 20, since the horizontal height of the left and right sections of the track 20 is the same, the limiting component 33 and the adapter 31 can basically maintain the first vertical distance H1.
[0036] The above analysis and explanation only focuses on the lifting and lowering process of the limiting component 33 in one road surface installation environment of the track 20. It is understood that in the actual use environment, the road surface environment of the track 20 is not the same. However, when the door body 10 drives the limiting component 33 to slide along the track 20 through the movable component 32, the limiting component 33 can lift and lower relative to the adapter 31 by relying on the lifting and lowering degree of freedom provided by the movable component 32, so as to pass through different height positions in the track 20.
[0037] like Figure 3 As shown, in some embodiments, the adapter 31 includes a fixing plate 311 and a fixing frame 312. The fixing plate 311 extends along the bottom of the door body 10 and is used to fit against and fix to the bottom of the door body 10. The fixing frame 312 is connected to the fixing plate 311 and extends downward. The fixing frame 312 is connected to one end of the movable component 32.
[0038] In this embodiment, by extending the fixing plate 311 along the bottom of the door body 10 and fitting it to the bottom of the door body 10, a certain connection area can be ensured between the adapter 31 and the door body 10, thereby ensuring a good connection strength between the adapter 31 and the door body 10. By extending the fixing bracket 312 downward, a certain amount of space can be provided for one end of the movable component 32, avoiding motion interference between one end of the movable component 32 and the fixing plate 311 or the bottom surface of the door body 10 when it moves relative to the adapter 31.
[0039] The fixing plate 311 can extend along the bottom or side of the bottom beam 12 of the door body 10 and fit against the bottom or side of the bottom beam 12.
[0040] In practice, the adapter 31 can be fixed to the bottom beam 12 of the door body 10 by bolts or other fasteners, or the adapter 31 can be fixed to the bottom beam 12 of the door body 10 by welding.
[0041] like Figure 3 As shown, in some embodiments, the movable component 32 includes a connecting rod 321. One end of the connecting rod 321 is rotatably connected to the adapter 31, and the other end of the connecting rod 321 is rotatably connected to the limiting component 33. Thus, when the door 10 slides along the uneven track 20 via the movable component 32, the limiting component 33 can swing around one end of the connecting rod 321 to adjust the horizontal height of the limiting component 33. This avoids the limiting component 33 being blocked by the upper wall 2011 or the bottom wall 2012 of the limiting groove 201, preventing the limiting component 33 from continuing to slide. At the same time, the limiting component 33 can also rotate around the other end of the connecting rod 321 to adapt to the upper wall 2011 or the bottom wall 2012 of the limiting groove 201, which has an inclined angle, further reducing the risk of the limiting component 33 being blocked by the upper wall 2011 or the bottom wall 2012 of the limiting groove 201.
[0042] When the door 10 moves from a lower position to a higher position on the track 20 via the movable component 32, the limiting component 33 swings around one end of the connecting rod 321 as follows: Figures 4 to 5 As shown, the limiting component 33 swings counterclockwise around one end of the connecting rod 321 via the connecting rod 321; when the door 10 moves from a higher position to a lower position on the track 20 via the movable component 32, the swing change of the limiting component 33 around one end of the connecting rod 321 is as follows: Figures 5 to 4 As shown, the limiting component 33 swings clockwise around one end of the connecting rod 321 via the connecting rod 321.
[0043] like Figure 4 and Figure 5 As shown, when the door 10 moves the limiting component 33 through the movable component 32 across the flat section of the track 20, the limiting component 33 can remain horizontal; as Figure 6 As shown, when the door 10 drives the limiting component 33 through the movable component 32 to pass through the inclined section of the track 20, the limiting component 33 can rotate around the other end of the connecting rod 321 under the resistance of the track 20, so that the inclination angle of the limiting component 33 is consistent with the inclination angle of the section of the track 20, and can pass through the section of the track 20 smoothly.
[0044] Please see Figure 7 , Figure 7 for Figure 3 The exploded view of the movable component 32 shown indicates that, in some embodiments, the movable component 32 further includes a first bearing 322 and a second bearing 323. The first bearing 322 includes a first inner ring 3221 and a first outer ring 3222. The first outer ring 3222 is fitted over the outside of the first inner ring 3221. The first inner ring 3221 is used to connect with the adapter 31, and the first outer ring 3222 is connected to one end of the connecting rod 321. The second bearing 323 includes a second inner ring 3231 and a second outer ring 3232. The second outer ring 3232 is fitted over the outside of the second inner ring 3231. The second inner ring 3231 is connected to the limiting component 33, and the second outer ring 3232 is connected to the other end of the connecting rod 321.
[0045] In this embodiment, the two ends of the connecting rod 321 are connected to the adapter 31 and the limiting component 33 respectively through the bearing structure. This can reduce the rotational friction at the rotating connection, making it easier for the limiting component 33 to swing up and down relative to the door 10 through the movable component 32. At the same time, it can also improve the load capacity and impact resistance at the rotating connection. When the door 10 is subjected to external force and tends to derail or overturn, the limiting mechanism 30 can provide better resistance.
[0046] In some embodiments, the outer sidewall of the first inner ring 3221 and the inner sidewall of the first outer ring 3222 cooperate to form a first spherical pair, and the first outer ring 3222 can rotate and swing around the first inner ring 3221; the outer sidewall of the second inner ring 3231 and the inner sidewall of the second outer ring 3232 cooperate to form a second spherical pair, and the second outer ring 3232 can rotate and swing around the second inner ring 3231.
[0047] With the above settings, the connecting rod 321 has the freedom to rotate around its own axis between the first bearing 322 and the second bearing 323. When the door 10 is subjected to external force, causing the door 10 to tend to derail or tip over, in addition to being able to swing up and down relative to the door 10, the connecting rod 321 can also rotate around its own axis between the first bearing 322 and the second bearing 323, thereby adapting to the angle change of the door 10 and resisting the force exerted on the connecting rod 321 by the door 10, thus optimizing the force on the connecting rod 321 between the door 10 and the limiting component 33.
[0048] In some embodiments, the first inner ring 3221 is rotatably connected to the adapter 31 via a first rotating shaft, and the second inner ring 3231 is rotatably connected to the limiting component 33 via a second rotating shaft.
[0049] In the specific implementation process, the first bearing 322 and the second bearing 323 can be spherical plain bearings respectively.
[0050] In some other embodiments, the first bearing 322 and the second bearing 323 may be omitted, one end of the connecting rod 321 is directly rotatably connected to the door body 10 through the first rotating shaft, and the other end of the connecting rod 321 is directly rotatably connected to the limiting component 33 through the second rotating shaft.
[0051] like Figure 7 As shown, in some embodiments, the first bearing 322 further includes a first screw 3223, and the second bearing 323 further includes a second screw 3233. The first screw 3223 is fixedly connected to the first outer ring 3222, and the first screw 3223 is threadedly connected to one end of the connecting rod 321; the second screw 3233 is fixedly connected to the second outer ring 3232, and the second screw 3233 is threadedly connected to the other end of the connecting rod 321, and the threads on the first screw 3223 and the threads on the second screw 3233 have opposite helical directions.
[0052] In this embodiment, after the limiting component 33 is assembled onto the door body 10 and the track 20, rotating the connecting rod 321 along the axis of the connecting rod 321 in the first direction allows the first screw 3223 and the second screw 3233 to move closer to each other, thereby reducing the distance between the first bearing 322 and the second bearing 323, and thus reducing the axial length of the movable component 32. Conversely, rotating the connecting rod 321 along the axis of the connecting rod 321 in the second direction allows the first screw 3223 and the second screw 3233 to move further apart, thereby increasing the distance between the first bearing 322 and the second bearing 323, and thus increasing the axial length of the movable component 32. During use, the axial length of the movable component 32 can be adjusted as needed to allow the limiting mechanism 30 to adapt to the distance between the door body 10 and the track 20, improving the adaptability of the limiting component 33 to different road conditions.
[0053] The first direction and the second direction are opposite and both surround the axis of the connecting rod 321.
[0054] Specifically, one end of the connecting rod 321 is provided with a first internal threaded hole, and the outer circumferential wall of the first screw 3223 is provided with a first external thread, which is threadedly connected to the first internal threaded hole. The other end of the connecting rod 321 is provided with a second internal threaded hole, and the outer circumferential wall of the second screw 3233 is provided with a second external thread, which is threadedly connected to the second internal threaded hole. Alternatively, one end of the connecting rod 321 may have a first external thread on its outer circumferential wall, the first screw 3223 may have a first internal threaded hole, and the first external thread may be threadedly connected to the first internal threaded hole. The other end of the connecting rod 321 may have a second external thread on its outer circumferential wall, and the second screw 3233 may have a second internal threaded hole, which is threadedly connected to the second internal threaded hole.
[0055] In some embodiments, the connecting rod 321 is provided with a rotating part 3211, which provides a force application position for the manual rotation of the connecting rod 321, and can drive the connecting rod 321 to rotate. Specifically, the rotating part 3211 is a groove provided on the circumferential outer wall of the connecting rod 321, and / or, the rotating part 3211 is a through hole extending radially through the connecting rod 321.
[0056] In some embodiments, the first bearing 322 further includes a first nut 3224, which is threadedly connected to the first screw 3223 and abuts against the end face of one end of the connecting rod 321 to prevent the first screw 3223 from loosening from one end of the connecting rod 321, thereby improving the tightness of the connection between the first screw 3223 and the connecting rod 321. The second bearing 323 further includes a second nut 3234, which is threadedly connected to the second screw 3233 and abuts against the end face of the other end of the connecting rod 321 to prevent the second screw 3233 from loosening from the other end of the connecting rod 321, thereby improving the tightness of the connection between the second screw 3233 and the connecting rod 321.
[0057] Please see Figure 8 , Figure 8This is a side view of the structure of the limiting mechanism 30 according to another embodiment of the present invention, showing the cooperation between the movable component 32 and the limiting component 33. In other embodiments, the movable component 32 includes a flexible connector 321a, one end of which is connected to the adapter 31, and the other end of which is connected to the limiting component 33. Thus, when the door 10 slides along the uneven track 20 via the movable component 32 driving the limiting component 33, the flexible connector 321a is in a taut state, and the limiting component 33 can move around the flexible connector 321a. One end of the connector 321a swings to achieve lifting and lowering, thereby adjusting the horizontal height of the limiting component 33. This prevents the limiting component 33 from being blocked by the upper wall 2011 or the bottom wall 2012 of the limiting groove 201, which would prevent the limiting component 33 from continuing to slide. At the same time, the limiting component 33 can also rotate around the other end of the flexible connector 321a to adapt to the upper wall 2011 or the bottom wall 2012 of the limiting groove 201, which has an inclined angle, further reducing the risk of the limiting component 33 being blocked by the upper wall 2011 or the bottom wall 2012 of the limiting groove 201.
[0058] In addition, such as Figure 8 As shown, when the door 10 is subjected to external force, causing it to tend to derail or tip over, the flexible connector 321a can be tightened, and one end of it will face towards... Figure 8 The paper should be tilted slightly outwards or towards... Figure 8 The paper is slightly tilted inward to adapt to the angle change of the door 10 and resist the force exerted by the door 10 on the flexible connector 321a, thereby optimizing the force on the flexible connector 321a between the door 10 and the limiting component 33.
[0059] In some embodiments, the active component 32 further includes a first connecting ring 322a and a second connecting ring 323a. The first connecting ring 322a is connected to one end of the flexible connector 321a and is rotatably connected to the adapter 31. The second connecting ring 323a is connected to the other end of the flexible connector 321a and is rotatably connected to the limiting component 33.
[0060] In this embodiment, the two ends of the connecting rod 321 of the flexible connector 321a are connected to the adapter 31 and the limiting component 33 respectively through corresponding connecting rings. This allows the flexible connector 321a to rotate around the rotational connection between the first connecting ring 322a and the adapter 31, or around the rotational connection between the second connecting ring 323a and the limiting component 33, during the reciprocating sliding of the door body 10. This prevents the end of the flexible connector 321a from getting tangled on the adapter 31 or the limiting component 33, ensuring that the flexible connector 321a is in a straight line when taut.
[0061] Optionally, the flexible connector 321a can be a wire rope, chain, cloth belt, etc.
[0062] In some embodiments, the first connecting ring 322a is rotatably connected to the adapter 31 via a first rotating shaft, and the second connecting ring 323a is rotatably connected to the limiting component 33 via a second rotating shaft.
[0063] In some other embodiments, the first connecting ring 322a and the second connecting ring 323a may be omitted, and the two ends of the flexible connector 321a are directly connected to the adapter 31 and the limiting component 33, respectively.
[0064] In some embodiments, the track 20 is provided with two limiting grooves 201, which are located on both sides of the track 20 in the width direction Y. The limiting components 33 are respectively used to extend into the two limiting grooves 201. The limiting mechanism 30 has two sets of movable components 32, which are arranged side by side and spaced apart. One end of each set of movable components 32 is connected to the adapter 31, and the other end of each set of movable components 32 is connected to the limiting component 33.
[0065] In this embodiment, by setting two sets of movable components 32, the force between the adapter 31 and the limiting component 33 can be optimized, avoiding the single set of movable components 32 from being subjected to concentrated force on one side between the adapter 31 and the limiting component 33, thereby improving the stability of the connection between the adapter 31 and the limiting component 33.
[0066] like Figure 9 As shown, Figure 9 The diagram shows the cooperation between the limiting component 33 and the track 20. In some embodiments, the track 20 is provided with two limiting grooves 201 and two limiting parts 202. The two limiting grooves 201 are located on both sides of the track 20 in the width direction Y.
[0067] The upper wall 2011 of the limiting groove 201 is the lower surface of the limiting part 202, and the bottom wall 2012 of the limiting groove 201 is located below the upper wall 2011 of the limiting groove 201.
[0068] Please combine Figure 10 , Figure 10 for Figure 9The diagram shows a three-dimensional view of the limiting component 33. The limiting component 33 includes a base 331 and at least two first limiting members 332. The at least two first limiting members 332 are respectively connected to the base 331 and are respectively used to extend into two limiting grooves 201. The first limiting members 332 and their corresponding limiting portions 202 are opposite each other along the height direction Z of the track 20. Thus, each limiting portion 202 can restrict the corresponding first limiting member 332 from moving upwards and disengaging from its corresponding limiting groove 201. When an external force acts forward or backward on the door 10, causing the door 10 to tend to derail or overturn, the first limiting member 332 located on the rear or front side can resist the external force by abutting against the lower surface of the corresponding limiting part 202 (i.e., the upper wall 2011 of the limiting groove 201), so that the door 10 can slide smoothly along the length direction X of the track 20 or stop stably on the ground, thereby improving the smoothness of the door 10 when sliding and the stability when stopping.
[0069] The first limiting member 332 can be fully inserted into the limiting groove 201 or partially inserted into the limiting groove 201. It is only necessary that the first limiting member 332 is at least partially opposite to the limiting part 202 in the height direction Z of the track 20.
[0070] In some embodiments, the first limiting member 332 is a first roller, which is rotatably connected to the base 331 via a third rotating shaft, and the first roller can rotate around the third rotating shaft. By setting the first limiting member 332 as a roller structure, when friction occurs between the first limiting member 332 and the upper wall 2011 or the bottom wall 2012 of the limiting groove 201, the friction is rolling friction, thus reducing the frictional force between the first limiting member 332 and the upper wall 2011 or the bottom wall 2012 of the limiting groove 201.
[0071] The axis of the first roller coincides with the axis of the third rotating shaft and is parallel to the width direction Y of the track 20.
[0072] In some embodiments, the limiting component 33 further includes at least two second limiting members 333, which are respectively connected to the base 331. The at least two second limiting members 333 are respectively disposed on opposite sides or opposite sides of the two limiting portions 202 along the width direction Y of the track 20, and the second limiting members 333 are opposite to the limiting portions 202 along the width direction Y of the track 20. Thus, each limiting portion 202 can restrict the movement of the corresponding second limiting member 333 toward it along the width direction Y of the track 20. This ensures that the sliding process of the door 10 can only proceed along the length direction X of the track 20, thereby guiding the door 10 and preventing it from deviating during sliding. Furthermore, when an external force acts forward or backward on the door 10, causing it to tend to derail or overturn, the second limiting member 333 located on the rear or front side can resist the external force by abutting against the side surface of the limiting part 202, further improving the smoothness of the door 10 during sliding and its stability when stopped.
[0073] In some embodiments, the second limiting member 333 is a second roller, which is rotatably connected to the base 331 via a fourth rotating shaft and can rotate around the fourth rotating shaft. By setting the second limiting member 333 as a roller structure, when the second limiting member 333 rubs against the side surface of the limiting part 202, the friction is rolling friction, thereby reducing the frictional force between the second limiting member 333 and the side surface of the limiting part 202.
[0074] The axis of the second roller coincides with the axis of the fourth rotating shaft and is parallel to the height direction of the track 20.
[0075] In some embodiments, the limiting component 33 further includes at least one third limiting member 334, which is connected to the seat 331. The at least one third limiting member 334 is disposed on the upper side of the limiting part 202 and abuts against the limiting part 202. Thus, when the door body 10 drives the limiting component 33 to slide along the track 20 via the movable component 32, the third limiting member 334 can abut against the upper surface of the limiting part 202 under the action of gravity and slide along the length direction X of the track 20. When the third limiting member 334 passes the upper surface of the limiting part 202 with an inclined angle, the third limiting member 334 can rise or fall along the upper surface, thereby driving the limiting component 33 to rise or fall as a whole.
[0076] In this embodiment, by providing a third limiting member 334 that abuts against the upper surface of the limiting part 202, the first limiting member 332 and the bottom wall 2012 of the limiting groove 201 can be spaced apart. In this way, the first limiting member 332 can be reduced from being easily stuck in the limiting groove 201 due to the accumulation of debris in the limiting groove 201.
[0077] In some embodiments, the third limiting member 334 is a third roller, which is rotatably connected to the base 331 via a fifth rotating shaft and can rotate around the fifth rotating shaft. By setting the third limiting member 334 as a roller structure, when the third limiting member 334 rubs against the upper surface of the limiting part 202, the friction is rolling friction, thereby reducing the frictional force between the third limiting member 334 and the upper surface of the limiting part 202.
[0078] The axis of the third roller coincides with the axis of the fifth rotating shaft and is parallel to the width direction Y of the track 20.
[0079] Please see Figure 9 In some embodiments, along the width direction Y of the track 20, the first limiting member 332 is spaced apart from the side wall 2013 of the limiting groove 201; along the height direction Y of the track 20, the first limiting member 332 is spaced apart from the upper wall 2011 and the bottom wall 2012 of the limiting groove 201; and along the width direction Y of the track 20, the second limiting member 333 is spaced apart from the side surface of the limiting part 202. During the normal sliding process of the door 10, the first limiting member 332 and the second limiting member 333 of the limiting assembly 33 driven by it may not contact the track 20, thereby reducing the sliding resistance of the limiting assembly 33; when the door 10 has a tendency to derail, overturn, or derail, the first limiting member 332 will abut against the upper wall 2011 of the limiting groove 201, and the second limiting member 333 will abut against the side surface of the limiting part 202.
[0080] Please see Figure 9 and Figure 10 In some embodiments, the seat 331 includes a first mounting plate 3311 and a second mounting plate 3312, which are arranged side by side and spaced apart. The first mounting plate 3311 and the second mounting plate 3312 are connected to each other, and the first mounting plate 3311 and the second mounting plate 3312 are respectively located on the side facing the openings of the two limiting grooves 201. The aforementioned at least two first limiting members 332 are respectively disposed on opposite sides of the first mounting plate 3311 and the second mounting plate 3312; the first mounting plate 3311 and the second mounting plate 3312 are respectively provided with mounting grooves 3313, the aforementioned at least two second limiting members 333 are respectively disposed in the mounting grooves 3313 of the first mounting plate 3311 and the second mounting plate 3312, and the second limiting members 333 extend out of the mounting grooves 3313; the aforementioned at least one third limiting member 334 is disposed between the first mounting plate 3311 and the second mounting plate 3312, and the third limiting member 334 is closer to the upper end of the first mounting plate 3311 and the second mounting plate 3312 than the first limiting members 332 and the second limiting members 333.
[0081] Please see Figure 9In some embodiments, the track 20 includes a limiting structure 21 extending along the length direction X of the track 20. Limiting grooves 201 are respectively provided on both sides of the limiting structure 21 along the width direction Y of the track 20. The openings of the limiting grooves 201 on both sides are opposite to each other. The limiting groove 201 has an upper wall 2011, a bottom wall 2012, and a side wall 2013, with the side wall 2013 located between the upper wall 2011 and the bottom wall 2012. The limiting structure 21 includes a first flange 211, a second flange 212, and a connecting portion 213. The first flange 211 is connected to the lower end of the connecting portion 213, and the second flange 212 is connected to the lower end of the connecting portion 213. The two ends of the first flange 211 extend out to opposite sides of the connecting portion 213 along the width direction Y of the track 20, and the two ends of the second flange 212 extend out to opposite sides of the connecting portion 213 along the width direction Y of the track 20, so that the first flange 211, the second flange 212 and the connecting portion 213 are connected to form an I-shape.
[0082] The second flange 212 extends to the two opposite ends of the connecting portion 213, which respectively form the aforementioned limiting portion 202.
[0083] The upper wall 2011 of the limiting groove 201 is the lower surface of the limiting part 202 of the second flange 212, the bottom wall 2012 of the limiting groove 201 is the upper surface of the first flange 211, and the side wall 2013 of the limiting groove 201 is the side surface of the connecting part 213.
[0084] Since the openings of the limiting grooves 201 on both sides are opposite to each other, the above-mentioned at least two second limiting members 333 can be respectively used to be provided on opposite sides of the two limiting parts 202 along the width direction Y of the track 20.
[0085] In some embodiments, the track 20 further includes a carrier rail 22, which is provided with a receiving cavity 203, and a limiting structure 21 is disposed within the receiving cavity 203, and the carrier rail 22 carries the limiting structure 21.
[0086] In other embodiments, the limiting structure 21 may also have other shapes, for example, the second flange 212 and the connecting portion 213 are connected to form a T-shape, that is to say, the limiting structure 21 in this embodiment and Figure 9 The limiting structure 21 in this embodiment differs from the one shown in the previous one in that it is omitted. Figure 9 The first flange 211 of the limiting structure 21 shown.
[0087] The bottom wall 2012 of the limiting groove 201 is the inner bottom surface of the accommodating cavity 203.
[0088] In other embodiments, the track 20 may also have other shapes and structures. For example, the track 20 includes a base plate and two side plates. The two side plates are spaced apart along the width direction Y of the track 20. The base plate is connected to the lower end of the two side plates. The two side plates are respectively provided with the aforementioned limiting grooves 201 on their opposite sides. The openings of the limiting grooves 201 on the two side plates face each other, and each side plate is provided with a limiting part 202 on the upper side of the corresponding limiting groove 201.
[0089] Since the openings of the limiting grooves 201 on both sides face each other, the above-mentioned at least two second limiting members 333 can be respectively used to be provided on the two limiting parts 202 facing each other along the width direction Y of the track 20.
