[0016] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present invention as follows.

[0017] As Figure 1-2 shown, a mask detection pressing device includes a bottom plate 1, two guide rails 2 and a pressing mechanism. The bottom plate 1 and the two guide rails 2 are both rectangular plate structures. The two guide rails 2 are respectively vertically arranged at both ends of the bottom plate 1. A detection port 6 is provided at the central position between the two guide rails on the bottom plate 1, and the detection port 6 is a circular groove.

[0018] Rectangular through grooves 8 are formed in both guide rails 2 and extend to the connection with the bottom plate 1. The pressing mechanism is arranged on the two guide rails 2 and includes a pressing ring 3, two pressing plates 4 and four sliders 5. The two pressing plates 4 are connected to both ends of the pressing ring 3. The four sliders 5 are respectively connected to the two sides of the two pressing plates 4, and the four sliders 5 are respectively sleeved on the two side columns of the rectangular through groove 8 in the two guide rails. The two pressing plates 4 pass through the rectangular through grooves 8 at both ends of the guide rails. The pressing ring 3 is located above the detection port 6 between the two guide rails at both ends. The diameter of the pressing ring 3 is larger than the diameter of the detection port 6. When pressing, the pressing ring 3 presses on the bottom plate 1 around the detection port.

[0019] A first screw hole 11 is provided at one end of the pressing plate 4 away from the pressing ring 3. A second screw hole 12 is provided at a position corresponding to the first screw hole on the lower bottom plate 1. A first bolt 9 is screwed into the first screw hole 11. The first bolt 9 matches the first screw hole 11 and the second screw hole 12. When pressing, by screwing the first bolt 9 on the pressing plate 4 into the first screw hole 11 and the second screw hole 12, the pressing ring 3 and the pressing plate 4 are fixed to the bottom plate 1 to press the mask tightly.

[0020] Reinforcing ribs 7 are provided at the connection between the bottoms of the two guide rails 2 and the bottom plate 1. The reinforcing ribs 7 are located on both sides of the second screw hole 12 and are used to support and reinforce the guide rails 2. Corresponding notches 14 are provided at positions on the same side of the four sliders 5 as the reinforcing ribs 7. The size of the notches 14 matches the size of the reinforcing ribs 7. When the sliders 5 slide down on the guide rails 2, the reinforcing ribs 7 pass through the notches 14 so that the pressing ring 3 and the pressing plate 4 contact the bottom plate 1.

[0021] Third screw holes 13 are formed on one side of the four sliders 5 adjacent to the notches. Second bolts 10 are screwed into the third screw holes 13. The second bolts 10 pass through the sliders 5 through the third screw holes 13 and abut against the side columns of the guide rails 2, which is used to fix the pressing ring 3 and the pressing plate 4 on the guide rails 2.

[0022] Working principle

[0023] Unfold the pleats of the mask and lay it flat on the detection port 6 on the bottom plate 1. Loosen the sliders 5 by rotating the second bolts 10 on the sliders 5, so that the sliders 5 slide down on the two guide rails 2 at both ends. When the sliders 5 slide down on the guide rails 2, the reinforcing ribs 7 pass through the notches 14 so that the pressing ring 3 and the pressing plate 4 contact the bottom plate 1. The pressing ring 3 and the pressing plate 4 move downward together to press the mask, so that the central part of the mask to be detected is aligned with the detection port 6. The pressing ring 3 presses on the bottom plate 1 around the detection port 6 to press the mask, and the pressing plate 4 presses the other edge parts of the mask. Then, screw the first bolt 9 on the pressing plate 4. The first bolt 9 is screwed into the first screw hole 11 and the second screw hole 12, so that the pressing ring 3 and the pressing plate 4 are tightly fixed on the bottom plate 1 to press the mask tightly. Finally, screw the second bolt 10 on the slider 5. The second bolt 10 passes through the third screw hole 13 and abuts against the two side columns of the guide rail 2 for secondary fixation, and then the detection device can be started to detect the mask.

[0024] After the detection is completed, turn the second bolt 10 counterclockwise to loosen the slider 5, and then turn the first bolt 9 counterclockwise to separate the pressing ring 3 and the pressing plate 4 from the bottom plate 1. Move the pressing ring 3 and the pressing plate 4 upward to a suitable position through the slider 5 and the guide rail 2, turn the second bolts 10 on the four sliders 5 to fix them, and finally remove the mask after detection.

[0025] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
