[0002] Dust detection refers to the monitoring and analysis of dust particles in the environment to evaluate their concentration and composition and determine whether they meet safety standards. Dust is one of the common pollutants produced by many industrial processes and operations, which may cause harm to human health and the environment. Therefore, dust detection is of great significance.

[0003] At present, the dust detectors on the market are mainly divided into two types: handheld and non-handheld. Handheld dust detectors (as shown in the attached manual) Figure 4 The non-handheld dust detector is usually supported by a bracket (see the attached manual).

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 In the embodiment of the utility model, the portable handheld dust detector comprises a support plate 1, legs 2 and a handheld dust detector body 11. Three legs 2 are arranged around the support plate 1. One end of the three legs 2 is hinged to the side of the support plate 1. A first rod tube 3 is installed in the middle of the support plate 1. A sliding sleeve 4 is sleeved on the first rod tube 3. A connecting rod 5 is arranged between the sliding sleeve 4 and the three legs 2. The two ends of the connecting rod 5 are respectively hinged to the legs 2 and the sliding sleeve 4. When the three legs 2 are slowly unfolded outward, the connecting rod 5 drives the The sliding sleeve 4 slides downward on the first rod barrel 3. When the three legs 2 are contracted, the connecting rod 5 drives the sliding sleeve 4 to slide upward on the first rod barrel 3. A limit plate 6 is installed at the bottom end of the first rod barrel 3. The diameter of the limit plate 6 is larger than the outer diameter of the first rod barrel 3. The setting of the limit plate 6 can prevent the sliding sleeve 4 from sliding out from the bottom of the first rod barrel 3 and causing damage. Three first magnetic plates 15 are evenly installed around the sliding sleeve 4. Second magnetic plates 16 are installed on the three legs 2. The first magnetic plates 15 and the second magnetic plates 16 are magnetically matched.

[0023] See also Figure 1A second rod barrel 7 is movably connected to the upper part of the first rod barrel 3, and a third rod barrel 8 is movably connected to the upper part of the second rod barrel 7. Locking screws 9 are installed on one side of the first rod barrel 3 and one side of the second rod barrel 7. The first rod barrel 3 and the second rod barrel 7, as well as the second rod barrel 7 and the third rod barrel 8 are relatively fixed by locking screws 9.

[0024] See also Figure 1-3 A dust detector mounting seat 10 is arranged on the upper part of the third rod barrel 8, a bottom plate 13 is arranged at the bottom of the dust detector mounting seat 10, a damping shaft 14 is arranged between the bottom plate 13 and the top of the third rod barrel 8, the dust detector mounting seat 10 and the third rod barrel 8 are connected to each other by the damping shaft 14, and the setting of the damping shaft 14 can facilitate personnel to adjust the angle of the dust detector mounting seat 10, so that the handheld dust detector body 11 can be directed to different directions for dust detection, and the handheld dust detector body 11 is arranged on the dust detector mounting seat 10. The dust detector body 11 is model JYB-6A, and a hand-cranked tightening assembly 12 is installed on one side of the dust detector mounting base 10. The dust detector mounting base 10 is relatively fixedly connected to the handheld dust detector body 11 through the hand-cranked tightening assembly 12. The hand-cranked tightening assembly 12 includes a nut 1201, a screw 1202 and a crank 1203. The nut 1201 is embedded in one side of the dust detector mounting base 10, and a screw 1202 is installed in the middle of the nut 1201. The crank 1203 is installed on the end of the screw 1202 located outside the dust detector mounting base 10.

[0025] The working principle of the utility model is:

[0026] During use, when it is necessary to continuously detect the dust concentration in the area, it is only necessary to install the handheld dust detector body 11 on the dust detector mounting base 10, and then expand the three legs 2 outward and place them on the ground in the area, so that continuous detection can be performed without the need for personnel to hold them. After use, the three legs 2 can be stored under the support plate 1. When the second magnetic plates 16 on the three legs 2 are close to the first rod cylinder 3, the second magnetic plates 16 will be magnetically attracted to the first magnetic plates 15 at the corresponding positions on the sliding sleeve 4 to fix the three legs 2. When it is necessary to detect the dust concentration in a higher area, it is only necessary to pull the second rod cylinder 7 out of the first rod cylinder 3, hold the second rod cylinder 7 and lift the handheld dust detector body 11 to a high place for detection. When it is necessary to perform non-continuous dust detection in a lower area, it is only necessary to loosen the crank 1203 to remove the handheld dust detector body 11 from the dust detector mounting base 10 for use.

[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
