Detailed Implementation
[0026] Example 1
[0027] like Figures 1-5 As shown, the portable air detector proposed in this embodiment includes a housing 1, an L-shaped cover plate 2, an air detector main unit 3, a limiting frame 5, a connecting strap 12, and two rotating blocks 7.
[0028] The upper end and one end of the outer casing 1 are both open; an L-shaped cover plate 2 covers the opening of the outer casing 1, and a sealing strip 4 is installed on the periphery of the L-shaped cover plate 2. The sealing strip 4 can improve the sealing between the outer casing 1 and the L-shaped cover plate 2. A rotating shaft is installed at the end of the L-shaped cover plate 2, and the L-shaped cover plate 2 is rotatably connected to the end of the outer casing 1 through the rotating shaft; elastic reset components are installed at both ends of the rotating shaft. The elastic reset components include a cylinder 16 and a measuring tape spring 17. The cylinder 16 is located at the end of the outer casing 1, and the measuring tape spring 17 is installed inside the cylinder 16 to drive the rotating shaft to automatically reset.
[0029] The connecting strap 12 is connected to the L-shaped cover plate 2. The connecting strap 12 moves through the bottom end of the outer shell 1 and is connected to the slider 9. The outer shell 1 is equipped with a driving assembly for driving the slider 9 to move. The driving assembly includes an L-shaped moving plate 8 and a wedge block 10. The L-shaped moving plate 8 is slidably disposed in the middle of the outer shell 1. A fixing plate 6 is provided on one side of the bottom end of the outer shell 1. A connecting rod 11 is connected between the wedge block 10 and the L-shaped moving plate 8. The slider 9 is provided with an insertion hole, and the connecting rod 11 passes through the insertion hole.
[0030] The limiting frame 5 is located inside the outer casing 1, and the air detector main unit 3 is located inside the limiting frame 5; multiple sets of first buffer components 13 are installed at the bottom of the inner wall of the outer casing 1; multiple sets of second buffer components 14 are installed around the inner wall of the outer casing 1.
[0031] Both rotating blocks 7 are rotatably installed on the inner ends of the housing 1. The rotating blocks 7 are used to limit the air detector main unit 3 and the limiting frame 5. Driving the rotating blocks 7 to rotate until they are parallel to the side of the limiting frame 5 allows the air detector main unit 3 to be removed.
[0032] In this embodiment, moving the L-shaped movable plate 8 moves the wedge block 10, and the inclined surface of the wedge block 10 presses the slider 9 to move. The movement of the slider 9 moves the connecting belt 12, and the connecting belt 12 pulls the L-shaped cover plate 2 to rotate. At this time, the L-shaped cover plate 2 automatically opens, and the display screen and operation panel on the air detector host 3 are exposed, so that the detection work can begin. The cooperation between the fixed plate 6 and the L-shaped movable plate 8 makes it easy for the operator to hold. When the instrument is removed from the hand, the L-shaped cover plate 2 is driven to rotate and reset under the elastic force of the measuring tape spring 17. The L-shaped cover plate 2 closes the opening of the outer shell 1, so that the air detector host 3 is completely placed in the sealed cavity, which can protect the air detector host 3.

The first sleeve 131 is located at the bottom of the inner wall of the outer casing 1. The end of the first movable rod 132 is movably disposed inside the first sleeve 131 and connected to the first damping slider 134. The upper end of the first movable rod 132 abuts against the limiting frame 5. The first damping slider 134 is slidably disposed inside the first sleeve 131. The first spring 133 is sleeved and installed on the outside of the first movable rod 132. The second buffer assembly 14 includes a second sleeve 141, a second movable rod 142, and a first spring 133. The system comprises two springs 143, a second damping slider 144, and a hemispherical block 145. A second sleeve 141 is connected to the inner wall of the outer casing 1. The end of a second movable rod 142 is movably disposed inside the second sleeve 141 and connected to the second damping slider 144.
