Description
Technical field
This utility model relates to rolling screen door technical field, particularly relates to rolling screen door anti-fall-off device for the driving chain.
Background technology
Electric rolling door lifting is driven by door roller, and door roller typically drives spool turns by chain-drive mechanism, and reel drives the door curtain being wrapped on reel to slide up and down along door curtain guide rail and realizes switch gate.After use after a while, driving chain can elongated fluff, and sprocket wheel also can produce because of abrasion and axially rock, and makes the gear teeth and chain not to align, frequently can lead to chain, once fall chain, and door curtain can cause contingency because of deadweight tenesmus.
Utility model content
This utility model overcomes the deficiencies in the prior art, it is provided that a kind of rolling screen door anti-fall-off device for the driving chain that can prevent chain from coming off from sprocket wheel.
This utility model is achieved through the following technical solutions:
Drive sprocket and spool that rolling screen door anti-fall-off device for the driving chain, the spool including supporting plate, fixing connection for the reel and drum center being wound around door curtain and door roller connect fix the driven sprocket of connection, driving chain；Described supporting plate is located at door opening both sides；Described spool and supporting plate are rotationally connected；Supporting plate side is located at by described drive sprocket and driven sprocket；Described driving chain connects drive sprocket and driven sprocket；Described driving chain is provided with the chain-falling device of strip at drive sprocket and driven sprocket, and described chain-falling device is provided with base and upper cover；On described base, middle part is provided with groove, and the degree of depth of this groove and the width of driving chain match；Being covered on submounts on described, its size, shape and base match；The two ends correspondence position of described base and upper cover is provided with screw hole；Described chain-falling device is fixed on supporting plate through screw hole by screw, and makes groove be in the plane at driving chain place；Described driving chain is connected through groove with drive sprocket and driven sprocket.
During installation, being first placed between driving chain and supporting plate by base, make the groove of base be in the plane at driving chain place, if any deviation, available pad adjusts；Cover upper cover, lock screw again.Driving chain is play the guiding role by chain-falling device, can effectively prevent driving chain from coming off from drive sprocket or driven sprocket.
Preferably, described chain-falling device is provided with 4.4 chain-falling devices are divided into driving chain up and down at drive sprocket and driven sprocket, and when making drive sprocket and driven sprocket rotate and reverse, driving chain is all without coming off.
Preferably, described chain-falling device tilts to be fixed on supporting plate.Chain-falling device can be made closer to drive sprocket and driven sprocket.
Preferably, the two ends, bottom of described base are provided with boss.Boss is set and can reduce the contact surface of base and supporting plate, it is simple to be fixing.
Preferably, described spool is rotationally connected by bearing and supporting plate.Arranging bearing makes spool rotation more smooth and easy.
The beneficial effects of the utility model are: arrange chain-falling device at drive sprocket and driven sprocket at driving chain, and chain is play the guiding role by chain-falling device, can effectively prevent driving chain from coming off from drive sprocket or driven sprocket.
