Description

Derailment-preventing PVC (polyvinyl chloride) quick door Technical Field The utility model relates to the technical field of roller shutter doors, in particular to an anti-derailment PVC (polyvinyl chloride) rapid door. Background The industrial PVC rapid door is widely applied at present and is mainly installed on the access way and the internal logistics passage opening of workshops and plants. Has effects of sound insulation, heat preservation, wind resistance, etc. The door body structure of the existing PVC rapid door is designed to be single (door curtain: the door curtain is formed by connecting a plurality of PVC soft curtains through aluminum alloy ribs, so that an integral door curtain is formed, the aluminum alloy ribs have a certain bending resistance), the design of the structure has certain requirements on the environment in which the type of door is used, some complex environments cannot be used (such as a logistics door opening with large outdoor wind force, a workshop door opening with negative pressure in the interior, a logistics door opening with wide door opening size and the like, the aluminum alloy ribs can be bent and deformed to a large extent when the door body operates, the design requirements are exceeded), the phenomenon that the door curtain (4) is out of track (the door curtain overflows from a slide way) easily occurs when the door curtain is opened and closed, the aluminum alloy ribs interfere with the joint of the slide way and the door head after the door curtain is out of track, the door curtain cannot operate, and the door curtain is required to be maintained (the aluminum alloy ribs are forcedly placed into the slide way). Therefore, a structure capable of avoiding occurrence of door curtain derailment caused by deformation of the door curtain due to environmental influence during operation of the door curtain is needed, and the bottleneck of limitation of the use environment of the PVC soft curtain rapid door is effectively solved, so that the industrial door has wider use environment. Disclosure of utility model The utility model aims to provide an anti-derailment PVC rapid door, which can limit two ends of a door curtain in a slideway, avoid the phenomenon of derailment of the door curtain (overflow of the door curtain from the slideway) when the door curtain is opened and closed, cancel aluminum alloy ribs, reduce aluminum alloy materials required for PVC rapid door production and reduce production cost. In order to achieve the above-mentioned purpose, provide a PVC rapid door of anticreep rail, including slide, curtain and winding mechanism, actuating mechanism is installed to winding mechanism's one end, include by motor drive's reel in the winding mechanism, and actuating mechanism control reel is rotatory, the upper end of curtain is fixed around establishing on winding mechanism's reel, slide symmetry fixed connection is in winding mechanism's bottom both sides, the lower extreme of curtain wears out from winding mechanism's bottom, the opening that supplies the curtain to get into is all offered to the opposite end of last both sides slide of winding mechanism, and the curtain extends to in the slide through the opening, the equal equidistant fixedly connected with of both sides end of curtain is a plurality of nylon Long Huakuai, and the nylon slider is located the slide, the one end equidistance screw thread installation of curtain has a plurality of guide screw, and the guide screw is located nylon slider's front and back both sides respectively, both ends all are equipped with the deflector and with guide plate sliding connection, the groove of nylon slider surface has been seted up the guide plate, and the nylon slider slides in groove, the guide beam and the guide beam is equipped with the guide beam, and the bottom beam is equipped with the bottom beam is installed to the both ends respectively to the bottom beam, the bottom beam is connected with the bottom beam respectively to the slide. Can restrict the both ends of door curtain in the slide, the phenomenon of door curtain derailment overflows the slide appears when avoiding the door curtain to open and close to cancel the aluminum alloy rib, reduce the aluminum alloy material that PVC rapid door production needs to use, reduction in production cost. According to the derailment-preventing PVC rapid door, the door curtain is of an integral PVC soft curtain structure without wind-resistant ribs. Deformation of the wind-resistant rib is avoided when the door body operates by canceling the wind-resistant rib, and the door body can be used continuously after being repaired manually. According to the derailment-preventing PVC rapid door, two anti-collision rubber strips are fixedly connected to the inner wall of the slideway, and are respectively positioned on two sides of the opening of the slideway. The anti-collision rubber strip is used for avoiding the nylon sliding block from being in direct contact
