[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1 As shown, an embodiment of this utility model provides a grid plate with a sealing and isolation function, including a grid frame 1, a sealing flap 2, a driving assembly, and a limiting assembly mounted on the grid frame 1. The grid frame 1 is divided into multiple ventilation openings 3 arranged in an array, and multiple sets of sealing flaps 2 are installed in the ventilation openings 3 in a corresponding manner. The sealing flaps 2 are rotatably connected to the grid frame 1 via a rotating shaft, so that the sealing flaps 2 can reciprocate relative to the grid frame 1 to switch between an open state and a closed state.
[0026] The drive assembly is connected to the sealing flap 2 and is configured to drive multiple sets of sealing flaps 2 to rotate synchronously. The limiting assembly is configured to restrict the rotation of the sealing flap 2, so that the sealing flap 2 is kept in the open or closed state; when the sealing flap 2 is kept in the closed state, the sealing flap 2 can seal with the grid frame 1, thereby achieving the sealing and isolation of the grid plate. In the event of emergencies such as hazardous chemical leaks, fires, or dense smoke, the drive assembly can drive the sealing flap 2 to flip to the closed state, and the limiting assembly can keep the sealing flap 2 in the closed state, thereby sealing the grid plate and preventing the spread of toxic substances through the grid plate.
[0027] like Figure 5 As shown, to ensure a sealing effect, a sealing gasket 4 can be provided on the edge of the sealing flap 2 for sealing cooperation with the grid frame 1. Specifically, the sealing gasket 4 can be directly covered on the edge of the sealing flap 2 by adhesive bonding.
[0028] As an optional implementation method, such as Figures 1-3 As shown, the driving assembly in this embodiment mainly includes a driving rod 5, a rotating rod 6, a transmission link 7, and multiple swing arms 8. The rotating rod 6 is rotatably mounted on the grid frame 1, with one end connected to the driving rod 5 and the other end hinged to the transmission link 7. The swing arms 8 are correspondingly arranged with the sealing flaps 2, with one end hinged to the transmission link 7 and the other end fixedly connected to the rotating shaft of the corresponding sealing flap 2. When the driving rod 5 moves, causing the rotating rod 6 to rotate, the transmission link 7 moves accordingly, causing the multiple swing arms 8 to rotate synchronously, thereby driving multiple sets of sealing flaps 2 to rotate synchronously via the swing arms 8. It can be understood that sealing flaps 2 located in the same row can be installed on the same rotating shaft, thus being driven by the same swing arm 8.
[0029] Furthermore, such as Figure 4 As shown, the limiting component in this embodiment of the present invention includes a limiting plate 9 installed on the grid frame 1. The limiting plate 9 is located on one side of the drive rod 5, and a first limiting protrusion 10 and a second limiting protrusion 11 are spaced apart on the side of the limiting plate 9 facing the drive rod 5. The drive rod 5 has a limiting groove 12 for the first limiting protrusion 10 or the second limiting protrusion 11 to engage. When the limiting groove 12 engages with the first limiting protrusion 10, the sealing flap 2 remains in the open state, and the grid plate is normally ventilated. When the limiting groove 12 engages with the second limiting protrusion 11, the sealing flap 2 remains in the closed state, sealing the grid plate.
[0030] Furthermore, multiple first limiting protrusions 10 can be spaced apart to restrict the sealing flap 2 to different opening angles. For example, in this embodiment of the invention, two first limiting protrusions 10 are spaced apart on the limiting plate 9. The two first limiting protrusions 10 can respectively restrict the sealing flap 2 to a 90° open state (i.e., fully open state) and a 45° open state (i.e., half-open state). When the sealing flap 2 is held in the 90° open state, the grid plate is transparent, and the ventilation effect is optimal; when the sealing flap 2 is held in the 45° open state, it does not affect the normal ventilation of the grid plate, and can also play a certain role in shielding and protecting it.
[0031] Furthermore, in this embodiment of the invention, the drive rod 5 is hinged to the rotating rod 6. After moving the drive rod 5 to rotate the sealing flap 2 to the desired position, the drive rod 5 can be rotated towards the limiting plate 9 so that the limiting groove 12 on the drive rod 5 can engage with the corresponding limiting protrusion, thereby holding the sealing flap 2 in the desired position; rotating the drive rod 5 in the opposite direction can release the limiting, making it convenient to readjust the sealing flap 2.
[0032] Furthermore, both the first limiting protrusion 10 and the second limiting protrusion 11 are elastically connected to the limiting plate 9, so that the first limiting protrusion 10 and the second limiting protrusion 11 can pop out or compress relative to the limiting plate 9. When the limiting protrusions are used to engage and limit the drive rod 5, the single limiting protrusion engaged with the limiting groove 12 pops out normally, while the remaining limiting protrusions can be compressed under the pressure of the drive rod 5, avoiding interference with the drive rod 5 and affecting the limiting effect.
[0033] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this utility model. Those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
