Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense engineering, and more specifically, to an auxiliary positioning device for detecting the opening and closing force of a civil air defense door leaf. Background Technique

[0002] As the entrance and exit of a civil air defense project, the civil air defense door plays a very crucial role in protective equipment. In a state of preparing for war, the flexibility of opening and closing the civil air defense door is directly related to the life and property safety of the people. Therefore, an auxiliary positioning device for detecting the opening and closing force of a civil air defense door leaf is usually used to detect the opening and closing force of the civil air defense door.

[0003] However, in the existing technology, the equipment for detecting the opening and closing force of a civil air defense door leaf mainly consists of a digital display push-pull force gauge and an auxiliary positioning mechanism. During the detection operation of the opening and closing force of a civil air defense door leaf, when the digital display push-pull force gauge is stressed, it is necessary to ensure the stability of the force on the digital display push-pull force gauge. However, the current fixed connection method is likely to affect the accuracy and efficiency of detecting the opening and closing force of a civil air defense door leaf. In view of this, we propose an auxiliary positioning device for detecting the opening and closing force of a civil air defense door leaf. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the existing technology, adapt to the actual needs, and provide an auxiliary positioning device for detecting the opening and closing force of a civil air defense door leaf, so as to solve the technical problem that the fixed connection method of the current equipment for detecting the opening and closing force of a civil air defense door leaf is likely to affect the accuracy and efficiency of detecting the opening and closing force of a civil air defense door leaf.

A plurality of clamps for fixing the handle are detachably installed at equal intervals on one side of the extension arm.

[0008] The utility model realizes the pulling of the civil air defense door body arranged in the door frame through the positioning mechanism to realize the opening and closing force detection. During the detection, the connecting seat provided with the extension arm is driven to rotate by the torsion mechanism, so as to complete the twisting of the handle and release the fixation between the door frame and the civil air defense door body. Then, the driving arm is driven to swing by the driving mechanism, so as to drive the bending between the connecting seat and the extension arm, and the opening and closing force is detected through the torsion mechanism. The adoption of the movable connection greatly improves the accuracy and efficiency of the opening and closing force detection of the civil air defense door leaf.

[0009] Preferably, the torsion mechanism includes a servo motor, the servo motor is fixedly installed on one side of the driving arm away from the connecting seat, and a rotating seat is fixedly installed at one end of the motor shaft of the servo motor passing through the driving arm.
