A high-resistance airtight protective door with manual and electric control

Abstract

The invention discloses a manual and electric control high-resistance airtight protective door. The door comprises a door frame, a translation hinge, a door leaf, an actuating mechanism and a sensor.The door frame is fixed in a wall body, the door leaf is fixed on the door frame through the translation hinge; the actuating mechanism is arranged on the door leaf, is combined with the door leaf, and comprises a driving wheel, a locking device, a manual operation wheel, a motor and a clutch, the driving wheel is arranged on the lower portion of the door leaf and connected with the motor throughthe transmission device, the locking device is arranged on the attaching face of the door leaf and the door frame and connected with the motor and the manual operation wheel through the transmission device, the clutch is arranged on a branch where the motor controls the driving wheel and the locking device, and the sensor detects the opening and closing states of the locking device and the door leaf. The protective door has the advantages of high strength, high resistance and good sealing performance, the executing mechanism is well combined with the door leaf, the structure of the door leaf is not affected, manual and electric opening and closing of the protective door are achieved, and electric control has the advantages of being efficient, stable and reliable.

Description

technical field [0001] The invention relates to the technical field of protective doors, in particular to a manually and electrically controlled high-resistance airtight protective door. Background technique [0002] At present, the research and development of high-resistance doors needs to solve the two problems of door body resistance and electric control scheme. In the prior art, the method of thickening the size of the door body is generally used to improve the resistance of the door body, but the weight of the door body is greatly increased, and manual operation is impossible or extremely difficult. When using electric operation, a large torque is required, and more power is bound to be required. Driven by a special motor, it also brings difficulties in the installation and setting of the motor, and the existing protective doors are relatively single in form, which is not suitable for electric sealing of large-span openings; the setting of the electric control mechanism...

Problems solved by technology

In the prior art, the method of thickening the size of the door body is generally used to improve the resistance of the door body, but the weight of the door body is greatly increased, and manual operation is impossible or extremely difficult. When using electric operation, a large torque is required, and more power is bound to be required. Driven by a special motor, it also brings difficulties in the installation and setting of the motor, and the existing protective doors are relatively single in form, which is not suitable for electric sealing of large-span openings; the setting of the electric control mechanism needs to meet the requirements of easy opening and closing of the door body Under the premise, ensure the high resistance and sealing characteristics of the door body, and after combining with the door body, avoid affecting the structural strength and stability of the door body
