Description

Technical Field

[0001] This utility model relates to the field of ceiling technology, and in particular to a ceiling opening and closing component. Background Technology

[0002] With the booming development of the modern sports industry and large-scale performing arts events, sports venues have transformed from simple sports venues into multifunctional public spaces that integrate competitions, performances, and exhibitions. People have placed higher demands on the environmental comfort and functional versatility of venues, hoping for adequate shelter and protection during inclement weather, while also desiring natural ventilation and lighting during sunny days.

[0003] Traditional roofs are typically fixed or open-air, making it difficult to meet the aforementioned requirements. Therefore, it is necessary to provide a roof opening and closing component to solve these technical problems. Utility Model Content

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides a roof opening and closing component that achieves rapid opening and closing of the roof through the combined action of a large movable roof and a small movable roof, so as to meet the flexible adjustment of the stadium under different weather conditions and activity needs.

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

[0006] The ceiling opening and closing assembly includes: two movable large sliding ceilings and two movable small sliding ceilings installed on the top of the ceiling. When the ceiling is open, the large sliding ceilings are directly above the small sliding ceilings; when the ceiling is closed, the two large sliding ceilings are in contact. It also includes two moving tracks on which both the large and small sliding ceilings travel. Each track has two long moving slots and one short moving slot. The large sliding ceilings move along the long moving slots, and the small sliding ceilings move along the short moving slots. Multiple rollers are installed at the bottom of both the large and small sliding ceilings, each located in a different long or short moving slot. Two drive mechanisms are installed on the large sliding ceilings to drive their movement. Each drive mechanism includes a drive motor fixed to the large sliding ceiling, multiple sprockets, and a chain. The multiple sprockets are connected to the corresponding rollers via shafts. A drive sprocket is installed on the drive motor, and the chain is mounted on the multiple sprockets and the drive sprocket.

[0007] Preferably, multiple tension sprockets are rotatably mounted on the large movable top, and the multiple tension sprockets tension the chain so that the chain located below is in constant contact with the sprockets.

[0008] Preferably, an active traction plate is fixed inside the tail of the large movable top, and a passive traction plate is fixed outside the front end of the small movable top. When the large movable top is closing and moving, the active traction plate on it comes into contact with the passive traction plate, and the large movable top drives the small movable top to move.

[0009] Preferably, the bottom of the short moving groove is inclined at an angle between 1° and 3°, with the section of the two short moving grooves that are close to each other being higher and the section that is far apart from each other being lower.

[0010] Preferably, at least four locking mechanisms are provided on the moving track, and the at least four locking mechanisms are evenly distributed in different long moving slots for fixing the large moving top after opening or merging. The locking mechanism includes a locking block that moves in the limiting slot and a telescopic rod fixed to the bottom of the moving track. The telescopic rod is fixed to the locking block.

[0011] Preferably, rubber pads are installed on the sections of the two large movable tops that are close to each other. When the two large movable tops come into contact and close, the rubber pads play a certain buffering role and protect both large movable tops.

[0012] Preferably, a plurality of first pressure sensors are installed on the moving track, pressure plates are fixed on both sides of the two large moving tops, and second pressure sensors are also installed at both ends of the moving track.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0029] Example 1

[0030] like Figure 1-7As shown, the ceiling opening and closing assembly provided by this utility model includes: two movable large sliding tops 2 and two movable small sliding tops 3 installed on the top of the ceiling 1. When the top of the ceiling 1 is in the open state, the large sliding tops 2 are directly above the small sliding tops 3; when the top of the ceiling 1 is in the closed state, the two large sliding tops 2 are in contact. It also includes two moving tracks 4, on which both the large sliding tops 2 and the small sliding tops 3 travel. The moving tracks 4 have two long moving grooves 5 and short moving grooves 6. The large sliding tops 2 move along the long moving grooves 5, and the small sliding tops 3 move along the short moving grooves 6. Multiple rollers 7 are installed at the bottom of both the large sliding tops 2 and the small sliding tops 3, and the multiple rollers 7 are respectively located in different long moving grooves 5 and short moving grooves 6. Two drive mechanisms are installed on the large movable roof 2 to drive its movement. Each drive mechanism includes a drive motor 8 fixed to the large movable roof 2, multiple sprockets 9, and a chain 10. The multiple sprockets 9 are connected to corresponding rollers 7 via shafts. A drive sprocket is mounted on the drive motor 8, and the chain 10 is mounted on the multiple sprockets 9 and the drive sprocket. When the drive motor 8 starts, it drives the multiple sprockets 9 to rotate via the drive sprocket and the chain 10. The rotation of the sprockets 9 drives the rollers 7 to rotate, thereby realizing the movement of the large movable roof 2. Because both the large movable roof 2 and the small movable roof 3 are movable, the roof can be opened and closed.

[0031] Furthermore, multiple tension sprockets 11 are rotatably mounted on the large movable top 2. The multiple tension sprockets 11 tension the chain 10, so that the chain 10 located below is always in contact with the sprocket 9. This ensures that the chain 10 can drive the sprocket 9 to rotate when the drive motor 8 is in forward or reverse rotation.

[0032] Example 2

[0033] like Figure 7 As shown, an active traction plate 12 is fixed inside the tail of the large movable top 2, and a passive traction plate 13 is fixed outside the front end of the small movable top 3. When the large movable top 2 is closing and moving, the active traction plate 12 on it comes into contact with the passive traction plate 13, and the large movable top 2 drives the small movable top 3 to move.

[0034] Furthermore, such as Figure 9As shown, the bottom of the short moving groove 6 is inclined at an angle between 1° and 3°. The section of the two short moving grooves 6 that are close to each other is higher, and the section that is far apart from each other is lower. In this case, when the large moving top 2 moves the small moving top 3 while it is closed, the small moving top 3 is in a climbing state. This greatly reduces the possibility of the small moving top 3 lurching forward at the moment when the active traction plate 12 and the passive traction plate 13 come into contact, thus ensuring that the small moving top 3 moves forward stably. When the large moving top 2 is opened, it moves back, and the small moving top 3 moves back under the influence of gravity and the inclined groove. During the back movement, the active traction plate 12 and the passive traction plate 13 come into contact, which prevents the small moving top 3 from moving back too quickly, avoids the risk of loss of control, and ensures that the small moving top 3 moves back stably.

[0035] Example 3

[0036] like Figure 4 and 8 As shown, at least four locking mechanisms are provided on the moving track 4. These four locking mechanisms are evenly distributed in different long moving slots 5 to fix the large moving top 2 after it is opened or merged. Each locking mechanism includes a locking block 15 that moves in the limiting slot 14 and a telescopic rod 16 fixed to the bottom of the moving track 4. The telescopic rod 16 is, but is not limited to, an electric push rod 16. The telescopic rod 16 is fixed to the locking block 15. When the large moving top 2 moves to the designated position, the telescopic rod 16 is activated. The telescopic rod 16 drives the locking block 15 to move and insert between the two rollers 7, so that the large moving top 2 cannot move back and forth, thereby achieving the locking and fixing of the large moving top 2.

[0037] Example 4

[0038] like Figure 4 As shown, rubber pads 17 are installed on the sections of the two large movable tops 2 that are close to each other. When the two large movable tops 2 come into contact and close, the rubber pads 17 play a certain buffering role and protect both large movable tops 2.

[0039] Example 5

[0040] like Figure 4As shown, multiple first pressure sensors 18 are installed on the moving track 4. Pressure plates 19 are fixed to both sides of the two large moving tops 2. When the two large moving tops 2 come into contact, the pressure plates 19 press against the first pressure sensors 18, which then send a signal to shut off the drive motor 8, thus stopping the large moving tops 2. At this time, the drive motor 8 can start in reverse. Second pressure sensors 20 are also installed at both ends of the moving track 4. As the two large moving tops 2 unfold away from each other, when a large moving top 2 comes into contact with a second pressure sensor 20, the second pressure sensor 20 sends a signal to shut off the drive motor 8, which can then start in the forward direction. The arrangement of the first pressure sensors 18 and the second pressure sensors 20 ensures that the large moving tops 2 can stop in a timely manner.

[0041] Working principle: The large movable top 2 is driven by the motor 8, which drives the roller 7 to move along the long moving groove 5 via the sprocket 9 and chain 10. At the same time, the tension sprocket 11 ensures that the chain 10 is always engaged with the sprocket 9, ensuring driving stability. When closed, the large movable top 2 pushes the passive traction plate 13 of the small movable top 3 through the active traction plate 12, causing the small movable top 3 to climb along the inclined short moving groove 6. When opened, the small movable top 3 moves back under the action of gravity and its speed is limited by the active traction plate 12 to ensure smooth movement.

[0042] After the large moving top 2 and the small moving top 3 come to a stop, the locking mechanism pushes the locking block 15 through the telescopic rod 16 to lock it between the rollers 7 to fix the position of the large moving top 2. The rubber pad 17 buffers the closing impact. The first pressure sensor 18 and the second pressure sensor 20 control the start and stop position of the large moving top 2 to achieve precise opening and closing control.
