a shutter mechanism

Abstract

The invention relates to design of roller shutter mechanisms used for protection, in particular to a roller shutter mechanism. The roller shutter mechanism comprises a roller shutter, a roller shuttershaft, a steel strip rolling shaft, a sliding rail, a first motor, a second motor and a stop switch assembly. A steel strip is arranged at the tail end of the roller shutter, and the roller shutter shaft is used for rolling the roller shutter; the steel strip rolling shaft is used for rolling the steel strip in the direction opposite to the rolling direction of the roller shutter, and the slidingrail is used for limiting the rolling direction of the roller shutter; the first motor drives the roller shutter shaft to rotate by starting a transmission pair through the roller shutter, and the second motor drives the steel strip rolling shaft to rotate by stopping the transmission pair; and the stop switch assembly is used for controlling the first motor to shut down when the roller shutter is in a fully-rolled state, and further used for controlling the second motor to shut down when the roller shutter is in a fully-unrolled state. According to the roller shutter mechanism, the problem that when a roller shutter door is manually controlled, the roller shutter door cannot be fully stored or fully released is avoided is avoided, and the phenomenon that due to the negligence factor, when the roller shutter door is fully stored or fully released, the motors are not stopped, thus a rolling shaft of the roller shutter door continues rotating, and clamping stagnation is caused is also avoided, so that the hidden danger of accident occurrence is eradicated.

Description

technical field [0001] The invention relates to the design of a roller shutter mechanism for protection, in particular to a roller shutter mechanism. Background technique [0002] The rolling shutter door for aircraft is a key protective accessory for the transparent window of the reconnaissance equipment on the airframe. As an automatic opening and closing mechanism to protect the optical transparent parts built in the equipment cabin, it plays an extremely important role in protecting the use of transparent parts. [0003] The driving mechanism of the rolling door switch is the key to ensure the normal use of the rolling door. In the conventional rolling door mechanism, the switch and the chain linkage mechanism are mostly controlled separately, the number of parts is large, and the operation is complicated, which is not conducive to the precise control of the rolling door switch and has low reliability.
