[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1:
[0025] like Figure 1-5As shown, a control device for airtight doors includes an equipment room 1 and two airtight doors 2. An automatic opening and closing control mechanism for the airtight doors 2 is installed on the top of the equipment room 1. The control mechanism includes a connecting block 3, a movable rod 4, a guide block 5, a transmission rod 6, an electric cylinder 7, and a guide bar 8. The top inner side of each airtight door 2 is fixedly installed to the connecting block 3. Each connecting block 3 is rotatably connected to one end of the corresponding movable rod 4. The other ends of both movable rods 4 are rotatably connected to one end of the transmission rod 6. The top of the transmission rod 6 is rotatably connected to the guide block 5. The guide block 5 is slidably connected to the guide bar 8. The other end of the transmission rod 6 is connected to the electric cylinder 7. The telescopic end is rotatably connected. There are two guide bars 8, and a groove is formed in the middle. The cross-section of the guide block 5 is square. The two sides of the guide block 5 are also connected to protrusions. The inner side of the two guide bars 8 is provided with grooves that cooperate with the protrusions. Two electric buttons 9 are installed on the outer wall of the equipment room 1. One electric button 9 is marked with the word "on" and the other electric button 9 is marked with the word "off". The electric button 9 is electrically connected to the output end of the processor and the input end of the processor. The output end of the processor is electrically connected to the input end of the relay. The output end of the relay is electrically connected to the electric cylinder 7. The scheme is reasonably designed, simple to operate, time-saving and labor-saving, and has a long service life.
[0026] Working principle: When opening the door using this device, pressing the electric button 9 marked "Open" sends a signal to the relay, which in turn controls the extension of the electric cylinder 7, pushing the transmission rod 6 to swing. With the sliding cooperation of the guide block 5 and the guide strip 8, the end of the transmission rod 6 moves, causing the movable rod 4 to open and push the airtight door 2 open. When closing the door using this device, pressing the electric button 9 marked "Close" sends a signal to the relay, which in turn controls the retraction of the electric cylinder 7, pulling the transmission rod 6 back. With the sliding cooperation of the guide block 5 and the guide strip 8, the end of the transmission rod 6 moves, causing the movable rod 4 to close and the airtight door 2 to close.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
