Description

Technical Field

[0001] The utility model relates to the field of air film buildings, in particular to a sealed door structure of an air film building. Background Art

[0002] An air-supported building refers to a building structure system that uses a special building membrane material as the outer shell and is equipped with a set of intelligent electromechanical equipment to provide positive air pressure inside the air-supported building to support the main body of the building.

[0003] After searching the patent document with the announcement number CN220285601U, the patent document discloses "a sealed door structure of an air film building, which can seal the gap between the door panel and the door frame when the door is closed through the sealing strip, and the door panel will enter the inner side of the door frame when the door is closed, so that the door panel and the inner frame are fitted together, and then the door panel and the inner frame can be closely fitted together through the sealing gasket on one side of the inner frame, thereby improving the overall sealing of the air film building and preventing the dust in the internal coal mine from polluting the external air.";

[0004] Although the above device uses structures such as sealing strips and sealing pads to ensure a good sealing effect after the sealing door is closed, it requires a lot of force to completely close and open the sealing door panel. For some women with less strength, it will be more difficult to open and close the sealing door panel. If the sealing door panel is not completely closed, the sealing effect is easily affected. Utility Model Content

[0005] The purpose of the utility model is to provide an air film building sealing door structure in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] An air film building sealed door structure comprises a door frame, a mounting groove is provided in the middle of the door frame, a sealing mechanism is installed at the front end of the mounting groove, and two sets of auxiliary mechanisms are also included;

[0008] The two sets of auxiliary mechanisms are respectively installed at the upper end and the lower end of the door frame. The auxiliary mechanism includes a motor. A screw is fixed at the output end of the motor. A sliding frame is threadedly connected to the outer periphery of the screw. The rear end of the sliding frame passes through the door frame. The sliding frame is slidably connected to the door frame. An ejection frame is fixed at the rear end of the sliding frame, and an ejection frame is fixed at one end of the sliding frame. An ejection switch is installed between the two sets of auxiliary mechanisms and at the front end of the door frame. Two ejection switches are installed on the inner wall of the mounting groove located at one end of the auxiliary mechanism.

[0009] Preferably, the two push-in switches are electrically connected to two corresponding motors respectively, and the push-out switch is electrically connected to the two motors.

[0010] Preferably, the button of the push-in switch protrudes three centimeters from the inner wall of the mounting groove.

[0011] Preferably, each inner wall of the installation groove is provided with a sealing rubber layer.

[0012] Preferably, the sealing mechanism comprises a door panel, the door panel is installed inside the installation groove, and a handle is fixed at the front end of the door panel.

[0013] Preferably: the upper and lower ends of the door panel and the rear end surface of the door panel are both provided with sealing rubber layers.

[0014] The beneficial effects compared with the prior art are as follows:

[0015] When the sealing door structure needs to be opened, the ejection switch is pressed to control the two motors to start. At this time, through the sliding connection between the sliding frame and the door frame and the threaded connection between the sliding frame and the screw, when the motor drives the screw to rotate, the sliding frame can move forward, allowing the ejection frame to support the sealing door structure, so that the sealing door structure is opened with some gaps, thereby facilitating the opening of the sealing door structure. When the sealing door structure needs to be closed and sealed, there is no need to completely close the sealing door structure. After the sealing door structure is closed to a certain extent, the sealing door structure will hit the two push-in switches, thereby driving the two motors in reverse. When the motor drives the screw to rotate in the opposite direction, the sliding frame can move backward, so that the push-in frame pushes the sealing door structure backward, so that the sealing door structure is completely closed and sealed. In this way, the device will not be too strenuous when closing and closing. BRIEF DESCRIPTION OF THE DRAWINGS

A screw rod 31 is fixed to the output end of the motor 3. A sliding frame 32 is threadedly connected to the outer periphery of the screw rod 31, and the rear end of the sliding frame 32 passes through the door frame 1. The sliding frame 32 is slidably connected to the door frame 1. An ejection frame 33 is fixed to the rear end of the sliding frame 32, and an ejection frame 34 is fixed to one end of the sliding frame 32. An ejection switch 35 is installed between the two groups of auxiliary mechanisms and at the front end of the door frame 1. Two ejection switches 36 are installed on the inner wall of the mounting groove 11 at one end of the auxiliary mechanism. The two ejection switches 36 are electrically connected to the two corresponding motors 3 respectively, and the ejection switch 35 is electrically connected to the two motors 3. The button of the ejection switch 36 protrudes three centimeters from the inner wall of the mounting groove 11; when the sealed door structure needs to be opened, the ejection switch 35 is pressed to control the two The motor 3 is started. At this time, through the sliding connection between the sliding frame 32 and the door frame 1 and the threaded connection between the sliding frame 32 and the screw rod 31, when the motor 3 drives the screw rod 31 to rotate, the sliding frame 32 can move forward, allowing the ejection frame 33 to support the sealing door structure, so that the sealing door structure is opened with some gaps, thereby facilitating the opening of the sealing door structure.

[0030] Working principle: when it is necessary to open the sealed door structure, press the ejection switch 35 to control the two motors 3 to start. At this time, through the sliding connection between the sliding frame 32 and the door frame 1 and the threaded connection between the sliding frame 32 and the screw 31, when the motor 3 drives the screw 31 to rotate, the sliding frame 32 can be moved forward, allowing the ejection frame 33 to support the door panel 2, so that the door panel 2 is opened a little gap, thereby facilitating the opening of the door panel 2. When the door panel 2 needs to be closed and sealed, there is no need to completely close the door panel 2. After the door panel 2 is closed to a certain extent, the door panel 2 will hit the two push-in switches 36, thereby driving the two motors 3 in the opposite direction. When the motor 3 drives the screw 31 to rotate in the opposite direction, the sliding frame 32 can be moved backward, so that the push-in frame 34 pushes the door panel 2 backward, so that the door panel 2 is completely closed and sealed. In this way, the device will not be too strenuous when closing and closing.
