Description

It is not easy the electrically driven curtain to skid

Technical field

The utility model belongs to technical field, more particularly, to a kind of electrically driven curtain for being not easy to skid.

Background technology

In existing electrically driven curtain, wheel is round setting, and smooth outer surface, the friction between idler wheel and track Power very little；To which during wheel moves, easily relative orbit skids, the phenomenon that causing to stagnate so that electricity Dynamic curtain can not normal movement, influence to use.

Utility model content

The utility model for overcome the deficiencies in the prior art, provides being not easy of being not easy to skid between a kind of wheel and track The electrically driven curtain of skidding.

To achieve the goals above, the utility model uses following technical scheme：A kind of electrically driven curtain for being not easy to skid, packet Include track and with the matched multiple attachment devices of the track；The attachment device includes the rolling that can be moved forward and backward along the track Wheel, the idler wheel are equipped with the anti-slip structure for increasing the frictional force between idler wheel and the track.The utility model is logical The frictional force increased between idler wheel and track for crossing the setting high degree of anti-slip structure, so that idler wheel is in movement It is not easy relative orbit in the process to skid, ensures the normal operation of electrically driven curtain.

Further, the idler wheel outer surface is that polymorphic structure is arranged to form the anti-slip structure；Due to abnormity The setting of structure so that the contact area between idler wheel and track obtains the increase of high degree, increases friction between the two Power, avoids that there is a situation where skid.

Preferably, the attachment device further includes one and the matched shock absorber part of the idler wheel；Pass through setting for shock absorber part It sets, may filter that idler wheel because vibrations caused by polymorphic structure, reach good damping effect, ensure that idler wheel is bonded rail always Road is moved.

Further, the outer surface of the idler wheel includes multiple continuous planes, has angle between adjacent two plane；Knot Structure is relatively simple, and molding is easy；And for the area of this kind of structure bottom roller outer surface compares traditional round roller, it is possible to increase 50% or more, good antiskid effect.

Further, it is intervally distributed with multiple grooves on the outer surface of the idler wheel, is equipped at least between adjacent two groove One contact surface；Due to the presence of groove so that the outer surface of idler wheel becomes no longer smooth, to can increase itself and track it Between frictional force.

Further, the contact surface is globoidal structure or planar structure or bending structure；Further increase idler wheel and rail Contact area before road enhances anti-slip effect.

Further, the attachment device further includes the reduction being connected with idler wheel, described shock absorber part one end and the deceleration Part is connected；It by the setting of reduction, prevents the rotating speed of idler wheel too fast, further suppresses the generation of slipping phenomenon.

Further, the shock absorber part is damping spring.

Further, the reduction is gear-box.

In conclusion the utility model has the following advantages：The frictional force between idler wheel and track can be increased, effectively prevent Idler wheel skids, and ensures the normal operation of electrically driven curtain.
