The utility model provides a stage fireproof curtain side blocking device which comprises side shielding plates, a driving seat and a connecting piece, and the side shielding plates are rotatably installed on the two sides of the front end of an external stage fixing frame. The side shielding plate is vertically arranged and is used for shielding a gap in the side part of the stage opening of the stage building when the fireproof curtain rises; the driving base is installed on the stage fixing frame in a sliding mode in the inclined direction. The driving seat is positioned below the end part of the fireproof curtain and is arranged close to the side shielding plate; the connecting piece is mounted between the side shielding plate and the driving seat; when the fireproof curtain falls down, the fireproof curtain presses the driving seat downwards to enable the driving seat to slide in the inclined downward direction, and then the side shielding plate is driven to rotate and be opened through the connecting piece. The stage fireproof curtain side blocking device overcomes the defect that a gap exists on the side face of an existing stage building platform opening due to the fact that a fireproof curtain is installed on the side face of the existing stage building platform opening.

Description

Technical Field

[0001] The utility model relates to the field of stage fire-proof curtains, in particular to a side blocking device of a stage fire-proof curtain. Background Art

[0002] With the continuous development of modern theater technology, the safety of theater stages has received more and more attention. Among them, fireproof isolation curtains, as an important part of theater safety, need to be designed reasonably and meet fire protection requirements. Stage fire curtains are special equipment for theater safety and fire protection. They are installed on the inside of the stage building entrance and between the stage and the back stage. They are metal barriers that separate the stage from the auditorium. When a fire occurs in the theater, the stage fire curtain can be freely lowered by pulling the hand switch when the power is cut off. The curtain body can quickly and safely land on the ground, cutting off the spread of a large amount of smoke and heat waves generated by the fire, protecting the evacuation of the audience and actors in time, and minimizing the loss of theater equipment.

[0003] Since the fire curtain is in a raised state under normal conditions, the current setting of the fire curtain will cause a gap or partition between the stage building entrance and other stage machinery and equipment, which lacks aesthetics from the outside. Utility Model Content

[0034] See also Figures 1 to 7 The utility model provides a side blocking device for a stage fire curtain, comprising a side blocking plate 1, a driving seat 2 and a connecting piece 3.

[0035] See also Figures 1 to 4, the side shielding plates 1 can be rotatably mounted on both sides of the front end of the external stage fixing frame 5; the side shielding plates 1 are arranged vertically to block the gap on the side of the stage building proscenium when the fire curtain 4 is raised. Among them, the side shielding plates 1 are rectangular. The driving seat 2 is slidably mounted on the stage fixing frame 5 in an inclined direction; the driving seat 2 is located below the end of the fire curtain 4 so that the driving seat 2 can be pressed down when the fire curtain 4 falls. The driving seat 2 is arranged close to the side shielding plates 1 for easy connection and driving. The connecting member 3 is connected between the side shielding plates 1 and the driving seat 2, and the driving seat 2 drives the fire curtain 4 through the connecting member 3. When the fire curtain 4 falls, the fire curtain 4 presses down the driving seat 2 to make the driving seat 2 slide in an oblique downward direction, and then the driving seat 2 drives the side shielding plates 1 to rotate and open through the connecting member 3.

[0036] In some embodiments, Figure 4 and Figure 5 As shown, a guide rail frame 6 is fixed on the stage fixing frame 5, an inclined guide rail 7 is installed on the guide rail frame 6 along the inclined direction, and the driving seat 2 is slidably installed on the inclined guide rail 7. A first slider 21 adapted to the inclined guide rail 7 is installed at the lower end of the driving seat 2, and the first slider 21 is slidably installed on the inclined guide rail 7. The inclined guide rail 7 and the first slider 21 cooperate to ensure that when the driving seat 2 is pressed, it can move along the inclined direction, thereby driving the side shielding plate 1 to open, thereby ensuring the feasibility of the structure.

[0037] In some embodiments, Figure 5 and Figure 6 As shown, a roller 22 is rotatably mounted on the upper end of the drive seat 2, and the roller 22 protrudes from the upper end surface of the drive seat 2, so that the fire curtain 4 first contacts the roller 22 when it falls. The drive seat 2 is L-shaped, and a roller shaft 23 is mounted on the upper end of the drive seat 2, and the roller 22 is mounted on the end of the roller shaft 23. The roller 22 is provided to reduce the friction between the drive seat 2 and the fire curtain 4 when the fire curtain 4 falls, thereby reducing wear.

When the fire curtain is lowered, under the action of the gravity of the fire curtain, the fire curtain presses down the drive seat through the roller, and the drive seat slides in an oblique downward direction. The drive seat drives the second slider to slide vertically through the pull rod. When the second slider slides, the side shielding plate rotates and opens, and the drive is simple and convenient. In order to facilitate resetting, a rebound member is installed between the side shielding plate 1 and the hinge frame 8. The rebound member can be a torsion spring, and the torsion spring is used to reset the side shielding plate 1.
