DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-6 , an embodiment provided by the utility model:

[0026] A dust sampler comprises: a main body, a sampling body 1, an operating panel 11 is provided on the surface of the sampling body 1, a bracket 12 is fixedly connected to one side of the sampling body 1, and a sampling tube 13 and an anemometer 14 are installed on the other side of the sampling body 1. The dust sampler can adjust the port of the sampling tube 13 to a suitable height through the bracket 12, and when using the dust sampler, the operation panel 11 can be operated to start the air pump in the sampling body 1, and external dust particles can be sucked into the inner wall of the sampling tube 13 and collected on the filter membrane for subsequent analysis and Research; The connecting mechanism includes a connecting tube 2, which is fixedly connected to the surface of the sampling body 1. A slide groove 21 and a storage groove 24 are provided on the surface of the connecting tube 2. A slider 22 is fixedly connected to the surface of the sampling tube 13. A slot 23 is provided on the surface of the slider 22. A groove 25 is provided inside the connecting tube 2. The surface of the storage groove 24 is movably connected with a support spring 26, an insert plate 27 and a connecting plate 28. The surface of the connecting plate 28 is fixedly connected with a pull rod 29. By pulling the pull rod 29, the connecting plate 28, the insert plate 27 and the support spring 26 can be driven to move together.

[0027] The inner diameter of the connecting tube 2 is the same as the outer diameter of the sampling tube 13. Two groups of slide grooves 21 and sliders 22 are provided. The two groups of slide grooves 21 are opened on both sides of the connecting tube 2, and the two groups of sliders 22 are installed on both sides of the sampling tube 13. The surface of the slide groove 21 is "L"-shaped, and the slider 22 is slidably connected to the surface of the slide groove 21. The sampling body 1 and the sampling tube 13 are connected through the connecting tube 2 and the slider 22, thereby changing the connection between the sampling body 1 and the sampling tube 13 to a plug-in and snap-fit ​​connection mode, and the outer diameter of the slider 22 is the same as the outer diameter of the connecting tube 2.

[0028] Two sets of support springs 26 are provided, and the two sets of support springs 26 are installed on both sides of the storage slot 24. One end of the support spring 26 is fixedly connected to the surface of the storage slot 24, and the other end of the support spring 26 is fixedly connected to the surface of the plug plate 27. The support spring 26 can apply a supporting force to the surface of the plug plate 27, thereby making the plug plate 27 and the slot 23 fit more tightly when the sampling tube 13 and the connecting tube 2 are connected, and at the same time, it can limit the position of the slider 22. The plug plate 27 is plugged into the surface of the slot 23. The cross-section of the connecting plate 28 is "L"-shaped. One side of the connecting plate 28 is fixedly connected to the surface of the plug plate 27, and the other side of the connecting plate 28 is slidably connected to the surface of the groove 25. The side of the connecting plate 28 away from the plug plate 27 always moves on the surface of the groove 25, which can limit the plug plate 27 and the support spring 26, thereby allowing the plug plate 27 and the support spring 26 to always move along the direction of the groove 25.

[0029] A protective mechanism is provided on the surface of the sampling body 1, which includes a cover plate 3, which is movably connected to the surface of the sampling body 1. A fixing plate 31 is fixedly connected to one side of the sampling body 1, and a limiting rod 35 is fixedly connected to the other side of the sampling body 1. A fixing block 32 is fixedly connected to one side of the cover plate 3, and a locking plate 36 is fixedly connected to the other side of the cover plate 3. A rotating block 33 is fixedly connected to the surface of the fixing plate 31, and a rotating groove 34 is provided on the surface of the fixing block 32. The cover plate 3 is made of a transparent and visible material, which can play a protective role while not preventing the operator from observing the data on the operation panel 11. Two sets of fixed plates 31 are provided, mounted on either side of the sampling body 1. Two sets of fixed blocks 32 and rotating blocks 33 are provided, mounted on either side of the fixed plates 31. The rotating blocks 33 are rotatably connected to the surface of a rotating groove 34, the diameter of which is the same as that of the rotating blocks 33. The sampling body 1 and the cover plate 3 are connected via the fixed plates 31 and the fixed blocks 32. The connection between the rotating groove 34 and the limiting rod 35 allows the cover plate 3 to rotate about the rotating block 33. The limiting rod 35 is longer than the length of the engaging plate 36, which has a U-shaped cross-section. One side of the engaging plate 36 is fixedly connected to the surface of the cover plate 3, while the other side engages the surface of the limiting rod 35. The connection between the limiting rod 35 and the engaging plate 36 allows the cover plate 3 to be positioned and adhered to the sampling body 1 for protection.

[0030] Working principle: After using the dust sampler, first move the pull rods 29 on both sides of the connecting tube 2 along the direction of the connecting plate 28 to drive the connecting plate 28 to slide along the surface of the groove 25, and also drive the plug-in plate 27 to slide on the surface of the slot 23 and cancel the plug-in state. At the same time, the support spring 26 is in a compressed state, and then the sampling tube 13 is moved to make the slider 22 slide on the surface of the slide groove 21. After that, the sampling tube 13 can be removed from the connecting tube 2 and the sampling body 1, and the slider 22 is also separated from the slide groove 21. At this time, the plug-in plate 27 is against the surface of the slide groove 21 under the action of the supporting force exerted by the support spring 26, and the connecting plate 28 away from the plug-in plate 27 is always active on the groove 25, and then the sampling tube 13 can be cleaned.

[0031] When using the dust sampler to sample dust, first operate the operation panel 11 and then move the cover 3 toward the surface of the sampling body 1, so that the cover 3 and the fixed block 32 rotate with the rotating block 33 as the center, and the rotating block 33 rotates on the surface of the rotating groove 34, and the locking plate 36 rotates to the limit rod 35. At this time, the locking plate 36 is bent toward the outside of the cover 3. When the cover 3 is attached to the sampling body 1, the locking plate 36 is released, and then the locking plate 36 restores its elastic deformation and is locked on the limit rod 35, which can complete the limitation of the cover 3, and the operator can observe the data on the operation panel 11 through the cover 3.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
