DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 4 A continuous instantaneous airflow drying chamber comprises a reinforcing support block 1 and a nozzle substrate 2. A plurality of connecting columns 3 are fixedly mounted on the surface of the reinforcing support block 1. The surface of the connecting column 3 is provided with threads, and a nut 4 is threadedly sleeved. A plurality of mounting grooves are circumferentially opened on the surface of the nut 4 away from the mounting grooves. A plurality of through openings respectively connected with the plurality of mounting grooves are circumferentially opened on the surface of the nut 4 away from the mounting grooves. A hollow rod 5 is slidably inserted in the mounting groove. A suction cup 6 is fixedly mounted on one end of the hollow rod 5. A ring 7 is fixedly mounted on one end of the plurality of hollow rods 5 away from the suction cup 6. The ring 7 is connected to the nut 4 through a telescopic component. The telescopic component comprises a plurality of telescopic springs 11 respectively sleeved on the plurality of hollow rods 5. The two ends of the telescopic spring 11 are respectively fixedly connected to the ring 7 and the nut 4.

[0024] A desorption port 8 is provided on the surface of the hollow rod 5, and a plurality of through-holes are provided in a circumferential shape on the surface of the ring 7, which are respectively connected to the plurality of hollow rods 5. A rotating shaft 9 is installed in the through-hole for sealing and rotation. A covering plate 10 for covering the desorption port 8 is fixedly installed at one end of the rotating shaft 9 located in the hollow rod 5 through a connecting rod. The rotating shaft 9 is connected to the ring 7 through a first elastic component, and the first elastic component includes a first torsion spring 12 sleeved on the rotating shaft 9. A mounting block is fixedly installed at one end of the rotating shaft 9, and both ends of the first torsion spring 12 are respectively fixedly connected to the ring 7 and the mounting block.

[0025] First, the nozzle substrate 2 is sleeved on the multiple connecting columns 3, and then the nut 4 is threadedly installed on the connecting column 3 until the nut 4 tightly presses the nozzle substrate 2 against the reinforcing support block 1. At this time, the control ring 7 moves so that the multiple suction cups 6 are pressed against the surface of the nozzle substrate 2. The suction cup 6 is deformed by the pressing force. Since the desorption port 8 is covered by the covering plate 10, the gas in the suction cup 6 will slip out from the gap between the suction cup 6 and the contact surface of the nozzle substrate 2, so that the multiple suction cups 6 will be adsorbed on the nozzle substrate 2, thereby fixing the nut 4. , preventing the nut 4 from rotating, improving the stability of the nut 4 fixing the nozzle substrate 2 and the strengthening support block 1, and when the nut 4 needs to be rotated, it is necessary to control the rotation of the multiple shafts 9 until the multiple cover plates 10 no longer cover the multiple desorption ports 8. At this time, the gas in the outside will enter from the multiple desorption ports 8, thereby releasing the adsorption between the multiple suction cups 6 and the nozzle substrate 2, and then releasing the fixation of the nut 4, and when the shaft 9 is loosened, the shaft 9 will quickly rotate and reset under the elastic potential energy of the first torsion spring 12, so that the cover plate 10 will also quickly rotate and reset, and cover the desorption port 8 again.

[0026] A mounting opening is provided on the surface of the nut 4, and a limiting assembly is provided in the mounting opening. The limiting assembly is used to limit the movement of the ring 7. The limiting assembly includes a rotating rod 13 rotatably installed in the mounting opening and an L-shaped limiting plate 14 fixedly sleeved on the rotating rod 13. The limiting plate 14 is connected to the wall of the mounting opening through a second elastic component. The second elastic component includes two second torsion springs 15 sleeved on the rotating rod 13. The two ends of the second torsion spring 15 are fixedly connected to the surface of the limiting plate 14 and the wall of the mounting opening respectively.

[0027] When the plurality of suction cups 6 are in contact with the nozzle substrate 2, the limiting plate 14 will contact with the ring 7, thereby limiting the movement of the ring 7. When it is necessary to control the movement of the ring 7 with the plurality of hollow rods 5 and the plurality of suction cups 6, the limiting plate 14 can be rotated until the limiting plate 14 no longer contacts with the ring 7, thereby releasing the restriction of the limiting plate 14 on the ring 7 and then controlling the movement of the ring 7.

[0028] In the present invention, the nozzle substrate 2 is first sleeved on the plurality of connecting columns 3, and then the nut 4 is threadedly installed on the connecting column 3 until the nut 4 tightly presses the nozzle substrate 2 against the reinforcing support block 1. At this time, the control ring 7 moves so that the plurality of suction cups 6 are pressed against the surface of the nozzle substrate 2. The suction cup 6 is deformed by the pressing force. Since the desorption port 8 is covered by the covering plate 10, the gas in the suction cup 6 will slip out from the gap between the suction cup 6 and the contact surface of the nozzle substrate 2, so that the plurality of suction cups 6 will be adsorbed on the nozzle substrate 2, thereby achieving the effect of fixing the nut 4. , preventing the nut 4 from rotating, thereby improving the stability of the nut 4 fixing the nozzle substrate 2 and the reinforcing support block 1. When the nut 4 needs to be rotated, it is necessary to control the rotation of the multiple rotating shafts 9 until the multiple covering plates 10 no longer cover the multiple desorption ports 8. At this time, the gas in the outside will enter from the multiple desorption ports 8, thereby releasing the adsorption between the multiple suction cups 6 and the nozzle substrate 2, and then releasing the fixation of the nut 4. After the nut 4 completes the fixation of the nozzle substrate 2 and the reinforcing support block 1, the position of the nut 4 can be fixed to prevent it from rotating, thereby improving the stability of the nut 4 fixing the nozzle substrate 2 and the reinforcing support block 1.

[0029] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
