Description

Fire and smoke-proof rolling shutter structure supporting device

The invention relates to a fire and smoke-proof rolling shutter structure supporting device, in particular to a fire-proof and smoke-proof rolling shutter structure that has both a whole roll and does not slip laterally when pulled. The two supporting structures support the fire-proof and smoke-proof rolling shutter structure evenly. Force is not easy to break, and the supporting structure has a smooth surface, which is easy to retract the fireproof and smokeproof rolling shutter structure supporting device.

Referring to FIGS. 7 and 8, a conventional fire and smoke-proof rolling shutter structure supporting device (for example, Republic of China Patent Publication No. 338480) mainly includes: a frame body 81 having a top plate 811, a bottom plate 812, a A front plate 813, a rear plate 814, and two end portions 815. The two end portions 815 are provided with two bearing portions 816; the bottom plate 812 is provided with an opening 817. A long rod body 82 is pivoted on the two bearing portions 816 at both ends, and is rotatable. A fire-proof and smoke-proof rolling shutter structure 83 is wound and fixed on the long rod body 82 and can be relatively moved (lowered or raised) through the opening 817. A plurality of supporting portions 84 each having a pair of fixed frames 841 and a pair of rollers 842. The pair of fixing frames 841 are fixed to the frame 81 (at least to the rear plate 814) and have a pair of horizontal support members 84A. The pair of rollers 842 are respectively pivoted on the pair of horizontal support members 84A and mutually It is parallel and free to rotate. The pair of rollers 842 are used to support the fire and smoke-proof rolling shutter structure 83. The requirement of the traditional device is that when the long rod body 82 and the fire and smoke-proof rolling shutter structure 83 sag due to their own weight, they can be supported by a plurality of rollers 842 to avoid being caused by the long rod body of the long rod body 82. The central part is bent downward. However, the aforementioned traditional design still produces the following problems: [1] The fire-proof and smoke-proof rolling shutter structure of the entire roll is liable to cause lateral slippage when pulled. As shown in FIG. 9, since the fire-proof and smoke-proof rolling shutter structure 83 is only “placed” in a first position PA on the pair of supporting rollers 842, its center of gravity lies between the two contact points of the pair of rollers 842. , So it can be fixed in a normal position. However, when the fire-proof and smoke-proof rolling shutter structure 83 is pulled down, since the opening 817 is biased to one side of the pair of rollers 842, the downward pulling force F1 will cause the fire-proof and smoke-proof rolling shutter structure 83 to generate a lateral component force F2, This makes the fire-proof and smoke-proof rolling shutter structure easy to move to a second position PB, and its center of gravity moves out between the pair of rollers 842. Causes the offset slippage to an abnormal position, which causes the problem of unsmooth operation. [2] The horizontal support is not easy to break due to insufficient bearing capacity. Referring to FIGS. 9 and 10, when the axial length of the long rod body 82 and the fire and smoke-proof rolling shutter structure 83 is very long, the overall weight increases, and the central part is easily bent down, so that the total weight is changed from the adjacent plural Each support portion 84 receives it. However, because the horizontal support member 84A is a "cantilever design" that extends horizontally, it is easy to break at the extended joint portion (marked as the X in the small circle frame), which often requires maintenance. In view of this, it is necessary to develop technologies that can solve the above-mentioned conventional disadvantages.

The purpose of the present invention is to provide a fire and smoke-proof rolling shutter structure supporting device, which has both the entire roll of fire-proof and smoke-proof rolling shutter structure being pulled horizontally when pulled, and the two supporting structures evenly support the fire-proof and smoke-proof rolling shutter structure. The average load is not easy to break, and the support structure has the advantages of smooth surface and easy to retract the fire-proof and smoke-proof rolling shutter structure. In particular, the problem to be solved by the present invention is that when the fire-proof and smoke-proof rolling shutter structure of the entire device that is produced by the conventional device is pulled, it is easy to cause lateral slippage, and the horizontal support is insufficient to easily break. The technical means for solving the above problems is to provide a fire and smoke-proof rolling shutter structure supporting device, which includes: a long frame structure having an elongated accommodating chamber and an elongated lower opening, the elongated lower opening is located in the elongated rim The bottom of the chamber, and the elongated opening has a pair of opening edge portions; a pair of supporting structures are respectively connected to the pair of opening edge portions, and are gradually expanded toward the elongated receiving room to form a supporting area, It is corresponding to the edge of the opening; a fire-proof smoke-proof rolling shutter structure is arranged in rolls on the pair of supporting structures and recessed in the supporting area; thereby, when the fire-proof smoke-proof rolling shutter structure passes the The process of lowering and closing between the opening edges is to maintain the depression in the support area to achieve a device that will not skew.
