The utility model discloses can prevent that the chain from coming off from the chain rim plate.
Description
Technical field
This utility model relates to rolling screen door technical field, particularly relates to a kind of 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 chain drum 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 chain drum.
This utility model is achieved through the following technical solutions:
Drive sprocket and spool that a kind of 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；The centre of described drive sprocket and driven sprocket is equipped with chain drum, and chain drum both sides are provided with gear chain drum, and the diameter of this gear chain drum is more than the external diameter of chain drum；Described gear chain drum connects by screw and chain drum are fixing；Described driving chain connects chain drum and the chain drum of driven sprocket of drive sprocket.
Preferably, the width more than driving chain of the distance between described gear chain drum, the twice less than driving chain width.
Preferably, the external diameter of described gear chain drum adds the height of twice chain section more than chain drum external diameter.
Preferably, described spool is rotationally connected by bearing and supporting plate.
The beneficial effects of the utility model are: use and arrange gear chain drum in the chain drum both sides of drive sprocket and driven sprocket, and the diameter of gear chain drum, more than the external diameter of chain drum, can effectively prevent from coming off the chain drum of the chain chain drum from drive sprocket or driven sprocket.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A sectional view of the present utility model.
Fig. 3 is the structural representation of the sprocket body of drive sprocket of the present utility model and driven sprocket.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
As shown in FIG. 1 to 3, embodiment of the present utility model, driven sprocket 5, the driving chain 6 connected fixed by drive sprocket 4 and spool 3 that the spool 3 including supporting plate 1, fixing connection for the reel 2 and drum center being wound around door curtain and door roller connect；Described supporting plate 1 is located at door opening both sides；Described spool 3 and supporting plate 1 are rotationally connected；Supporting plate 1 side is located at by described drive sprocket 4 and driven sprocket 5；The centre of described drive sprocket 4 and driven sprocket 5 is equipped with chain drum 7, and chain drum 7 both sides are provided with gear chain drum 8, and the diameter of this gear chain drum 8 is more than the external diameter of chain drum 7；Described gear chain drum 8 is by screw 9 and the fixing connection of chain drum 7；Described driving chain 6 connects the chain drum 7 of drive sprocket 4 and the chain drum 7 of driven sprocket 5.
The distance between described gear chain drum 8 width more than driving chain 6, the twice less than driving chain 6 width.
The external diameter of described gear chain drum 8 adds the height of twice chain section more than chain drum 7 external diameter.
Described spool 3 is rotationally connected by bearing 10 and supporting plate 1.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not limited thereto, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
