Resistance stop type ratchet wheel protection rotor wing door anti-clamping structure

Abstract

The invention relates to a resistance stop type ratchet wheel protection rotor wing door anti-clamping structure. The anti-clamping structure is mounted between a driving shaft and a driving side of a rotating door, and comprises a ratchet wheel and elastic pieces; the outer edge of the driving shaft is coaxially sleeved with the ratchet wheel through a shaft key; the ratchet wheel and the multiple elastic pieces realize one-way rotating fit structure; and the multiple elastic pieces are uniformly distributed and mounted on the driving side of the rotating door at intervals, and are positioned on the same horizontal plane. The resistance stop type ratchet wheel protection rotor wing door elastic pieces, provided by the invention, are static due to rotation stop of the rotating door; the ratchet wheel and the elastic pieces are reversely butted to cause deformation of the elastic pieces, so that the ratchet wheel and the elastic pieces cannot contact to lose fit; and the driving shaft drives the ratchet wheel to idly rotate, and the rotating door does no rotate to prevent the person clamping condition by the rotating door.

Description

technical field [0001] The invention belongs to the field of revolving doors, in particular to an anti-pinch structure of a resistance-stop ratchet protection revolving door. Background technique [0002] When the revolving door encounters pedestrians, rotors and fixed columns approaching a dangerous distance during use, the revolving door stops. This method is the most commonly used safety protection method for rotary wing doors at present, and this method is called the first-level safety protection. [0003] In some special circumstances, or the sensor fails, or the signal of the sensor is weakened, or due to a circuit problem, the primary safety protection may fail and cause personal injury. Therefore, in the drive structure design of the swing door driving wheel, the resistance stop type ratchet is used to protect the swing door. When the primary protection fails and the motor rotates, the swing door stops rotating under the action of the pressure that can be tolerated ...

AI Technical Summary

Problems solved by technology

[0004] But at present, the protection strategy of the revolving door is to improve the sensitivity of the sensor and increase the radiation range of the sensor to ensure its working efficiency, the precision of the sensor is also improved, and the failure rate is also increased. The structure of the revolving door is relatively rare, so it is difficult to avoid the situation of the revolving door clamping setting
