A kind of novel banister core device
Technical field
The present invention relates to a kind of mechanical transmission, relate to a kind of banister core device specifically.
Background technique
Traditional banister movement comprises motor, reducing gear and linkage mechanism.Motor provides power to reducing gear, reducing gear output shaft drivening rod mechanism, and the linkage mechanism transferring power is given the restrictor bar main shaft, and the restrictor bar main shaft drives the restrictor bar lifting.Traditional banister core device has following shortcoming:
One, reducing gear adopts single drive structure of gear worm, and efficient is low, and occurs the phenomenon that blocks easily.
Two, have the fixing lock direction of rising and falling, when needs change the lock direction of rising and falling, need change core device.Inconvenient user uses.
Three, do not possess engaging and disengaging gear is arranged, in the manual fluctuation restrictor bar, need shake the motor lifting lever, waste time and energy by handle.
Four, linkage mechanism links to each other with the output shaft of reducing gear, can't be fused into an integral body, and is succinct inadequately, attractive in appearance.
Summary of the invention
The object of the present invention is to provide a kind of novel banister core device, overcome the deficiency that traditional banister core device exists.
The following scheme of employing of the present invention realizes: construct a kind of novel banister core device, comprise that main motor 1, speed reducer 2, engaging and disengaging gear 3, spring equalizing device 4, restrictor bar main shaft 5 and bar are fixing device 6.
