Description

Technical Field

[0001] This application belongs to the field of security doors. Specifically, it relates to a dynamically balanced inflatable sealed security door. Background Art

[0002] A security door is a protective device designed to resist accidental failures of external devices in industrial buildings, safeguard the lives of personnel, keep the internal equipment of industrial buildings intact, prevent harm, and effectively stop the continuation of harm. It can be made of special industrial steel plates according to strictly set mechanical data and is equipped with high-performance hardware fittings to ensure the safety of life and property.

[0003] However, the sealing performance of existing security doors is not guaranteed. It depends on the gap size between the door body and the door hole, and has high requirements for processing technology. Summary of the Utility Model

[0004] In order to overcome the above-mentioned drawbacks in the prior art, the purpose of this application is to provide a dynamically balanced inflatable sealed security door, which has a simple and compact structure, can control the sealing performance of the security door by inflation, and further ensure safety.

[0005] The technical means adopted by this application to solve the above-mentioned technical problems is:

[0006] This application provides a dynamically balanced inflatable sealed security door, including:

[0007] A plate body, which is provided with a through hole;

[0008] A door body, which is hingedly connected to the plate body;

[0009] An inflatable sealing strip, which is arranged along the edge of the door body;

[0010] An inflation source, which is connected to the inflatable sealing strip through an inflation pipeline;

[0011] A control valve, which is installed on the inflation pipeline;

[0012] A pressure sensor, which is installed on the inflation pipeline;

[0013] A controller, which is respectively connected to the control valve and the pressure sensor.

[0014] Preferably, it further includes a handle, which is installed on the door body.

[0015] Preferably, it further includes a limit inductor, which is installed on the door body.

[0016] Preferably, it further includes an alarm, which is installed on the door body and is connected to the controller.

[0017] Compared with the prior art, the dynamic balance inflatable sealed safety door of the present application is provided with an inflatable sealing strip. When closing the door, the inflatable sealing strip is inflated through an inflation source. After the inflatable sealing strip expands, it fills the gap between the door body and the door hole, playing a sealing role. When opening the door, the inflation source evacuates the inflatable sealing strip, and the inflatable sealing strip shrinks and flattens, facilitating the operator to open the door body. At the same time, a control valve, a pressure sensor and a controller are provided. The pressure sensor senses the pressure of the inflatable sealing strip, and then it is convenient for the controller to control the switch of the control valve to realize the control of the state of the inflatable sealing strip. The structure is simple and compact, and the operation is convenient and fast, further ensuring the safety and stability of the safety door. BRIEF DESCRIPTION OF THE DRAWINGS
