Description

Technical Field

[0001] The utility model relates to the technical field of fire protection grilles, and in particular to a fire protection grille that is opened in a sliding manner. Background Art

[0002] Curtain wall facades mostly use independent glass curtain walls or independent grille systems. However, with the development of the construction industry, architects have begun to pursue complex and varied building facade effects. Double-layer composite curtain walls are now widely used in large public buildings. One of them is to use aluminum grilles on the glass curtain wall facades. The vertical grilles on the outside of the curtain wall are widely used by architectural designers and are a very common structure. However, fire rescue windows are inevitably set behind the grilles. Due to the existence of fire rescue windows, continuous small-pitch vertical grilles cannot be used, resulting in partial interruptions of the grilles. Designers have to compromise and adjust the plan, leaving regrets in the final building effect.

[0003] In the related art, a sliding grille is disclosed, including a wall, a fire rescue window is arranged on the wall, a fixed grille and a movable grille are arranged on the outer side of the wall, and the movable grille can be slidably arranged on the wall, and the position of the movable grille corresponds to the position of the fire rescue window. Its technical solution has the following beneficial effects: its movable grille completely adopts a mechanical structure, which is not only simple in overall structure and easy to implement, but also has no wearing parts, which greatly reduces the failure rate. When rescue is needed, firefighters can quickly open the grille outside the rescue window to expand the rescue area. After the rescue is completed, the grille will not hinder the restoration and installation of the outer curtain wall. After the restoration and installation of the outer curtain wall, the grille can be pushed back into the closed groove. The operation is very simple and practical.

[0004] However, there are still some shortcomings in the above structure. When the device is in use, there is no foothold for support during firefighting and rescue, which can easily cause firefighters to be injured and cause safety hazards.

[0005] Therefore, it is necessary to provide a new sliding opening fire grille to solve the above-mentioned technical problems. Utility Model Content

[0025] like Figure 3 As shown, the rotating mechanism includes two fixed mounting seats 110, two upper bases 13, three slide grooves 14, multiple steel grilles 12 and three rotating components. The two fixed mounting seats 110 are fixedly mounted on the top of the lower floor 3, the two upper bases 13 are fixedly mounted on the bottom of the upper floor 2, the three slide grooves 14 are respectively opened at the bottom of the slide groove 14 and the two upper bases 13, and the multiple steel grilles 12 are respectively rotatably mounted on the lower sliding seat 4 and the top of the two fixed mounting seats 110.

[0026] The rotating assembly includes a second motor 15, a plurality of second gears 16 and a toothed belt 17. The second motor 15 is fixedly mounted on the top inner wall of the slide 14. The plurality of second gears 16 are respectively fixedly mounted on the tops of the plurality of steel grilles 12. The output shaft of the second motor 15 is fixedly connected to the corresponding second gears 16. The toothed belt 17 is wound around the plurality of second gears 16, and the toothed belt 17 is meshed with the plurality of second gears 16.

[0027] By setting up a rotating mechanism, the steel grille 12 can be driven to rotate by starting the second motor 15, so that the steel grille 12 can be made parallel to the light direction according to the light direction, which is convenient for indoor lighting.

[0036] The working principle of the sliding fire grille provided by the utility model is as follows:

[0037] Step 1: When the fire grille is in a closed state, it is necessary to ensure indoor lighting, start the second motor 15 to drive the second gear 16 to rotate, and under the action of the multiple second gears 16 and the toothed belt 17, the multiple steel grilles 12 rotate, so that the angle of the steel grilles 12 can be adjusted according to the light direction, thereby ensuring the indoor lighting requirements;

[0038] The second step: when the fire grille needs to be opened, start the first motor 8 to drive the first gear 11 to rotate through the connecting shaft 10. Since the first gear 11 and the rack 7 are meshed, the lower slide 4 will move as a whole to open the fire rescue opening to facilitate the entry of firefighters. The setting of the lower floor 3 provides a foothold for firefighters, thereby providing firefighters with a safer rescue platform to avoid safety hazards.
