Abstract
The invention provides an anti-pressing device of an electric rolling door. The anti-pressing device comprises a first body which is in a shape of a strip and connected with a rolling sheet unit of the last sheet of the electric rolling door in hooked mode. At least one magnetic control switch is arranged in the first body, two sides of the first body are arranged in guiding rails on two sides of the electric rolling door in sliding mode, an electric conduction portion is respectively arranged on two sides of the first body, the two electric conduction portions are contacted with a circuit in the guiding rails on two sides of the electric rolling door in normal state, and the magnetic control switches are connected in series through leads between the two electric conduction portions. The anti-pressing device comprises a second body which is in a shape of a strip and sleeved on the bottom of the first body in sliding mode. The second body slides opposite to the first body vertically, and a magnetic component is arranged in the second body. When the bottom of the second body is pressed on an external object in contacted mode and the second body tends towards the first body vertically and oppositely, and the magnetic component can drive the magnetic control switches in the first body, so that the circuit between the guiding rails on two sides of the electric rolling door is disconnected or closed, and a signal is triggered to prevent the electric rolling door from descending continuously.
Description
Technical field
