Description

Technical Field

[0001] The utility model belongs to the field of rolling shutter door guide rail systems, and particularly relates to a low-noise and high-efficiency vibration-damping fireproof rolling shutter door guide rail system. Background Technique

[0002] A fireproof rolling shutter door is a rolling shutter that can meet the requirements of fire resistance stability and integrity together with the frame within a certain period of time, and is composed of a curtain board, a reel, a motor, a guide rail, a bracket, a protective cover, a control mechanism, etc. Fireproof rolling shutter doors are widely used in fire separation areas of industrial and civil buildings. The guide rail is one of the essential devices for fireproof rolling shutter doors. The quality of the guide rail directly affects the service life and user experience of the fireproof rolling shutter door.

[0003] However, most of the existing guide rails of fireproof rolling shutter doors are in direct contact with the door panels. When pulling the rolling shutter door to open or close, there is collision and friction between the rolling shutter door and the guide rail, shortening the service life of the rolling shutter door and generating abnormal noises, which are likely to affect the surrounding residents. Now, a low-noise and high-efficiency vibration-damping fireproof rolling shutter door guide rail system is provided to alleviate the above-mentioned problems. Summary of the Invention

[0004] The utility model realizes the purpose of low noise when the fireproof rolling shutter door is opened and closed by the cooperation of structures such as pulleys, a soundproof layer, and a second chute, so that the fireproof rolling shutter door body slides up and down through the pulleys inside the second chute.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A low-noise and high-efficiency vibration-damping fireproof rolling shutter door guide rail system includes a reel box. A driving mechanism is arranged inside the reel box, and a fireproof rolling shutter door body is driven and connected through the driving mechanism. It also includes guide rails installed at the bottom of the reel box on both sides of the fireproof rolling shutter door body. First chutes are opened on the upper surfaces of the two guide rails, and both sides of the fireproof rolling shutter door body are arranged inside the first chutes. Symmetrically distributed connecting frames are arranged between the fireproof rolling shutter door body and the inner side wall of the first chute. Second chutes are opened on both sides of the inner cavity wall of the first chute corresponding to the positions of the connecting frames. Pulleys are rotatably connected inside the opposite sides of the two connecting frames. An installation groove is opened on the inner bottom surface of the second chute, and a buffer assembly is arranged inside the installation groove.

[0007] Preferably, a rotating shaft is sleeved inside the middle position of the pulley. First connecting rods are connected to the opposite sides of the two connecting frames. A moving block is connected between the two first connecting rods. A second connecting rod is arranged on the outer side of the moving block close to the fireproof rolling shutter door body. The other end of the second connecting rod is connected to a fixed frame, and insertion holes are opened on both sides of the fixed frame that are in contact with the fireproof rolling shutter door body, and insertion rods are arranged inside the insertion holes.

[0008] Preferably, the buffer assembly includes a buffer plate, a support rod is arranged in the installation groove below the buffer plate, symmetrically distributed rotating plates are rotatably connected to the bottom of the buffer plate, moving cylinders are rotatably connected to one ends of the two rotating plates away from the buffer plate, a spring is connected between the two moving cylinders, and a plurality of elastic support round rods are connected to the bottom of the buffer plate.

[0009] Preferably, a sound insulation layer is arranged on the outer side of the second chute, rock wool is filled in the sound insulation layer, and abrasion-resistant strips are arranged on the sound insulation layer.

[0010] Preferably, the first chute has a rectangular structure, and the second chute has a semi-circular structure.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By arranging structures such as the first chute, the second chute, the pulley, the fixed frame, the sound insulation layer and the abrasion-resistant strips, the fireproof rolling shutter door body slides inside the second chute through the pulley, greatly reducing the friction of the fireproof rolling shutter door body against the guide rail, reducing noise, and the sound insulation layer arranged inside the second chute can effectively block the sound generated when the pulley moves in the second chute. The abrasion-resistant strips arranged on the sound insulation layer effectively relieve the abrasion of the fireproof rolling shutter door body against the guide rail and extend the service life.

[0013] 2. By arranging the installation groove and the buffer assembly, the elastic support round rods effectively buffer the vibration generated when the fireproof rolling shutter door is opened or closed. At the same time, when the bottom end of the fireproof rolling shutter door body applies pressure to the buffer plate, the moving cylinder is driven by the rotating plate to slide on the support rod, and the spring is compressed or stretched to buffer the movement of the fireproof rolling shutter door body, reducing the vibration amplitude and the risk of component damage.
