[0002] There are various types of environmental monitoring instruments. Among them, those used in dusty environments are called dust detectors. They are mainly used to detect the concentration of dust in ambient air. Dust detectors are classified into: laser dust detectors, online continuous monitoring dust detectors, portable dust detectors, etc. Dust detectors are widely used in disease prevention and control centers, mines, metallurgy, power plants, chemical manufacturing, health supervision, environmental protection, online environmental monitoring, etc.

[0003] Existing environmental dust detectors are not convenient for detecting dust at different heights, resulting in duplicated sample data that affects the detection results. Furthermore, existing environmental dust detectors are often portable, which is laborious and inconvenient for long-term testing. Therefore, we propose an environmental dust detector. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This environmental detector for dusty environments features an adjustment structure. When adjusting the height of the detector body to detect dust at different heights, pulling the levers on both sides moves the side plates outwards, causing the locking block to move out of a set of slots. Simultaneously, the connecting rod pulls the limiting block, which slides within the groove, compressing the spring. The locking block and the set of slots are no longer locked together, allowing the connecting rod to slide within the adjustment groove. This lifts the side plates, causing the placement plate to move upwards, changing the height of the detector body. Once the locking block is aligned with a set of slots at the appropriate height, the levers are released. Under the action of the spring, the limiting block moves, and the connecting rod pulls the side plates, causing them to press against the surface of the upright plate. This allows the locking block to insert into a set of slots at the appropriate height, thus fixing the position of the placement plate. This facilitates the detection of dust at different heights and avoids duplicate sample data affecting the detection effect.

[0014] 2. This environmental detector for dusty environments is equipped with casters, a handle, and a stand. The detector body is placed on the stand, and its position can be adjusted by using the casters and the handle. During long-term testing, there is no need to move it by hand, making it convenient to use. At the same time, the detector body is located between two sets of stand plates, which can protect the detector body from direct collision with external objects and increase its service life.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] An environmental detector for dusty environments includes a base plate 1, with casters 11 mounted on the bottom of the base plate 1. A handle 12 is fixedly connected to the surface of the base plate 1. An adjustment structure 2 is provided on the top of the base plate 1. The adjustment structure 2 includes two sets of upright plates 21, which are symmetrically arranged. An adjustment groove 22 is formed on the surface of the upright plates 21. Multiple slots 23 are formed on one side surface of the upright plates 21. A placement plate 24 is slidably connected between the two sets of upright plates 21. Sliding grooves 25 are formed on both sides of the placement plate 24. A side plate 26 is slidably connected to the surface of the upright plates 21. A handle 12 is fixedly connected to one side surface of the side plate 26. A connecting rod 29 is fixedly connected to the other side surface of the pull rod 27 and the side plate 26. A locking block 28 is sleeved on one side of the connecting rod 29, and a limiting block 211 is fixedly connected to the other side of the connecting rod 29. A spring 210 is fixedly connected to the surface of the limiting block 211. The top of the placement plate 24 is movably connected to the detector body 3, and an adjustment structure 2 is provided. When the height of the detector body 3 needs to be adjusted to detect dust at different heights, pulling the pull rods 27 on both sides moves the side plate 26 outward, causing the locking block 28 to move out of a set of slots 23. At the same time, the connecting rod 29 pulls the limiting block 211 in the sliding position. Sliding within slot 25 compresses spring 210, disengaging the locking block 28 from the set of slots 23. This allows connecting rod 29 to slide within adjusting slot 22, thereby lifting side plate 26 and moving placement plate 24 upwards. This changes the height of the detector body 3. Once locking block 28 is aligned with a set of slots 23 at the appropriate height, releasing pull rod 27 causes spring 210 to push limit block 211 to move. Connecting rod 29 then pulls side plate 26, causing it to press against the surface of upright plate 21, allowing locking block 28 to insert into a set of slots 23 at the appropriate height, thus fixing the position of placement plate 24. To facilitate the detection of dust at different heights and avoid the situation where repeated test sample data affects the detection effect, a caster wheel 11, a handle 12, and a stand plate 21 are provided. The detector body 3 is placed on the placement plate 24, and the position of the detector body 3 can be adjusted by the cooperation of the caster wheel 11 and the handle 12. During long-term testing, there is no need to move it by hand, which makes it more convenient to use. At the same time, the detector body 3 is located between two sets of stand plates 21, which can protect the detector body 3 from direct collision with external objects and increase its service life.

[0024] Furthermore, the surface of the handle 12 is provided with an anti-slip pad layer, which facilitates the movement of the base plate 1 via the handle 12.

[0025] Furthermore, the locking block 28 is fixedly connected to the side plate 26 away from the pull rod 27. A circular groove is opened on the surface of the locking block 28. The connecting rod 29 passes through the circular groove and is fixedly connected to the side plate 26. Pulling the pull rods 27 on both sides can drive the side plate 26 to move outward, so that the locking block 28 is moved out of a set of locking grooves 23. At the same time, the limiting block 211 is pulled by the connecting rod 29.

[0026] Furthermore, the adjusting groove 22 and the slot 23 are on the same vertical line. The adjusting groove 22 connects multiple sets of slots 23 to each other. The radius of the locking block 28 is equal to the radius of the slot 23. The connecting rod 29 is slidably connected inside the adjusting groove 22. When the locking block 28 moves out of a set of slots 23, the locking block 28 and the set of slots 23 no longer engage with each other, so that the connecting rod 29 can slide inside the adjusting groove 22.

[0027] Furthermore, the limiting block 211 is slidably connected inside the slide groove 25, and the connecting rod 29 passes through one side inner wall of the slide groove 25 and is fixedly connected to the limiting block 211. The radius of the limiting block 211 is larger than the radius of the connecting rod 29. The limiting block 211 limits the connecting rod 29 to prevent it from sliding out of the slide groove 25.

[0028] Furthermore, the two ends of the spring 210 are fixedly connected to the surface of the limiting block 211 and the inner wall of the slide groove 25, respectively. The spring 210 is sleeved on the outside of the connecting rod 29. When there is no external force, the limiting block 211 is reset by the spring 210. When the spring 210 is deformed, it will not interfere with the surface of the connecting rod 29.

[0029] Furthermore, a square groove is provided on the top of the placement plate 24, and a rubber pad is provided on the inner wall of the square groove. The detector body 3 is inserted into the square groove. The rubber pad protects the detector body 3 and provides a certain shock absorption function. The detector body 3 can be taken out of the square groove for use as needed.

[0030] Working principle: In use, the detector body 3 is placed on the placement plate 24. The position of the detector body 3 can be moved by the cooperation of the casters 11 and the handle 12. The upright plate 21 provides protection for the detector body 3, preventing direct collision with external objects. When it is necessary to adjust the height of the detector body 3 to detect dust at different heights, pull the pull rods 27 on both sides to move the side plates 26 outward, so that the locking block 28 moves out of a set of locking slots 23. At the same time, the connecting rod 29 pulls the limiting block 211 to slide in the slide groove 25, compressing the spring 210. The locking block 28 and the set of locking slots 23 are no longer locked together, allowing the connecting rod 29 to slide inside the adjusting groove 22. This allows the side plate 26 to be lifted, moving the placement plate 24 upward and changing the height of the detector body 3. After the locking block 28 is aligned with the set of locking slots 23 at the appropriate height, the pull rod 27 is released. Under the action of the spring 210, the limiting block 211 is pushed to move. The connecting rod 29 pulls the side plate 26, causing the side plate 26 to press against the surface of the upright plate 21, so that the locking block 28 is inserted into the set of locking slots 23 at the appropriate height, fixing the position of the placement plate 24. This allows for the detection of dust at different heights.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
