Electric winding device with replaceable platen

Abstract

Electric roll-hanging device with replaceable pressure plate, related to electric screen and electric roller blind products, it includes shell panel detachable relative to shell back plate, synchronous reversible micro-motor, roll tube, curtain or curtain, including slave shaft screw , micro switch, debugging bottom bar, auxiliary end of mid-sole bar, and especially includes a detachable and replaceable combined pressure plate. This design supports ordinary users to directly replace the pressure plate on the slave shaft screw, which greatly reduces product maintenance costs.

Description

technical field [0001] The present invention relates to an electric wind-up device with a replaceable pressure plate for a screen or curtain to be rolled up. Background technique [0002] Electric screen and electric roller blind products include housing, synchronous reversible micro-motor, roller tube, curtain / curtain, and auxiliary end frame including slave shaft screw, pressure plate, micro switch, switch seat, and adjustment bottom rod. The double-layer electric roller blinds that operate independently of each other include two components of the electric single roller blind except the casing. [0003] In the use of various electric coil hanging products, the closed round hole at the lower end of the pressure plate is pierced by the limit bottom rod, and the nut hole at the top of the pressure plate is pierced by the screw section of the slave shaft. As the slave shaft rotates forward and reverse according to the motor, the pressure plate The nut moves linearly from left...

Problems solved by technology

This phenomenon may not appear for a long time in screen products with slow speed and few times of use, but it may be unavoidable in classroom roller blind products with fast running speed (such as about 3 times the screen speed) and frequent ups and downs for many years
