[0003] like Figure 1 As shown, the existing dust sampler includes a dust sampler body 1, and most of them are fixed with a support frame 2 during dust sampling. When performing dust sampling, the support frame 2 is first placed on the ground, and then the support frame 2 is fixedly connected to the dust sampler body 1. The dust sampler body 1 is turned on, the sampling time is recorded, and the dust concentration is calculated using the difference between the weight of the filter membrane after sampling and the initial weight.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there is a defect that the dust sampler body 1 cannot be stored when the dust sampler body 1 is carried, making it inconvenient to move. Summary of the invention

[0005] In order to improve the problem of inconvenience in storage when carrying the dust sampler body, the present application provides a dust sampler and a method of using the same.

[0006] In the first aspect, the present application provides a dust sampler, which adopts the following technical solution:

[0007] A dust sampler comprises a storage box, the upper surface of which is provided with a storage groove for placing a dust sampler body, the side walls of the storage box are rotatably connected to a pair of connecting rods, each of the connecting rods is fixedly sleeved with a first support rod at the end away from the storage box, the first support rod is fixedly connected to a second support rod at one end away from the connecting rod, the first support rod is provided with a fixing hole, a fixing rod is slidably inserted in the fixing hole, the storage box is provided with a fixing groove for inserting the fixing rod, and each of the first support rods is connected to a clamping assembly for fixing the dust sampler body.

[0008] By adopting the above technical solution, when the dust sampler body is needed to perform dust sampling, the first support rod is in a vertical state, the fixing hole is opposite to the fixing slot, and the fixing rod passes through the fixing hole and is inserted into the fixing slot to fix the first support rod to the storage box.

[0009] Take out the dust sampler body from the storage slot, fix the dust sampler body with the clamping assembly, open the dust sampler body, and perform dust sampling.

[0010] After the dust sampling work is completed, the dust sampler body is closed, the restriction of the clamping assembly on the dust sampler body is released, and the dust sampler body is placed in the storage slot, which has the effect of facilitating the storage of the dust sampler body when carrying the dust sampler body.

[0011] Optionally, a pair of protrusions are fixedly connected to the upper surface of the storage box, a rotating rod is rotatably connected between the protrusions, and the rotating rod is fixedly sleeved with a box cover that abuts against the upper surface of the storage box.

[0012] By adopting the above technical solution, when the dust sampler body needs to be taken out, the box cover is turned away from the storage box to open the storage box. When the dust sampler body needs to be carried, the dust sampler body is placed in the storage slot, and the box cover is turned toward the storage box to close the storage box.

[0013] Optionally, the clamping assembly includes a first clamping rod fixedly connected to the first support rod, a second clamping rod being fixedly connected to the lower surface of the first clamping rod, a connecting hole being downwardly opened on the upper surface of the first clamping rod, a connecting bolt being rotatably connected in the connecting hole, a third clamping rod being threadedly connected to one end of the connecting bolt away from the first clamping rod, a plug-in rod being fixedly connected to the upper surface of the third clamping rod, and a plug-in groove being opened on the second clamping rod for the plug-in rod to be slidably inserted into.

[0014] By adopting the above technical solution, when the dust sampler body needs to be fixed, the dust sampler body is placed in the space surrounded by the first clamping rod, the second clamping rod and the third clamping rod, and the lower surface of the dust sampler body abuts against the upper surface of the third clamping rod. The connecting bolt is rotated, the third clamping rod moves toward the direction close to the first clamping rod, and the plug-in rod slides in the plug-in groove. When the upper surface of the dust sampler body abuts against the lower surface of the first clamping rod, the connecting bolt is stopped from rotating, and the first clamping rod and the third clamping rod fix the dust sampler body.

[0015] When the restriction on the dust sampler body needs to be released, the connecting bolt is loosened, the third clamping rod moves away from the first clamping rod, the upper surface of the dust sampler body is separated from the lower surface of the first clamping rod, and the restriction on the dust sampler body is released.

[0016] Optionally, a positioning rod is fixedly connected to the upper surface of the third clamping rod.

[0017] By adopting the above technical solution, when the dust sampler body needs to be fixed, the positioning rod realizes the positioning of the dust sampler body on the third clamping rod, reduces the possibility of the dust sampler body sliding in the length direction of the third clamping rod, and improves the overall stability.

[0018] Optionally, the side wall of the storage box having the fixing groove is connected to a locking assembly for fixing the first support rod.

[0019] By adopting the above technical solution, after completing the dust sampling work and placing the dust sampler body in the storage box, the first support rod is rotated to a horizontal position, the locking assembly fixes the first support rod, and the staff holds the second support rod to carry the dust sampler body.

[0020] Optionally, the locking assembly includes a mounting rod fixedly connected to the side wall of the storage box, the mounting rod having an end away from the storage box fixedly connected to a locking block, the upper surface of the locking block having a locking groove downwardly provided, the locking block having a mounting hole provided on a side away from the mounting rod, a locking rod slidably inserted in the mounting hole, the locking rod having an end away from the mounting rod fixedly connected to a pressure plate, a spring sleeved with the locking rod fixedly connected between the locking block and the pressure plate, the end of the locking rod in the locking groove is an inclined surface, and when the first support rod is in a horizontal state, the first support rod is inserted into the locking groove, and the locking rod abuts against the upper surface of the first support rod.

[0021] By adopting the above technical solution, when the first support rod needs to be moved, the pressing plate is pulled away from the locking block, and the pressing plate drives the locking rod to move, releases the restriction on the first support rod, and rotates the first support rod to separate the first support rod from the locking groove. Under the action of the spring, the locking rod moves to abut against the locking groove.

[0022] When the first support rod needs to be fixed, the first support rod is rotated toward the locking block, and the first support rod first contacts the inclined surface of the locking rod, and the locking rod moves away from the locking block under the action of the first support rod. When the first support rod abuts against the bottom of the locking groove, the locking rod moves toward the locking block under the action of the spring until it abuts against the locking groove, thereby fixing the first support rod.

[0023] During the process of inserting the first support rod into the locking groove, under the action of the inclined surface, the first support rod can be inserted into the locking groove without the need for the staff to manually separate the locking rod from the locking groove, making the fixing process of the first support rod simpler and more convenient.

[0024] Optionally, the connecting rod is connected to a fixing assembly for fixing the box cover.

[0025] By adopting the above technical solution, after the dust sampling work is completed and the dust sampler body is placed in the storage box, the fixing assembly fixes the box cover, thereby reducing the possibility of the box cover opening during the process of carrying the dust sampler body, causing the dust sampler body to fall out of the storage box, and improving the stability of the dust sampler body during the process of carrying the dust sampler body.

[0026] Optionally, a cavity is opened downward on the upper surface of the storage box, and the fixing assembly includes a gear placed in the cavity and fixedly connected to the end of the connecting rod away from the first support rod, the gear is meshingly connected with a rack, and the rack is slidingly connected to the vertical inner wall of the cavity, and a fastening groove for slidingly inserting the rack is opened on the side of the box cover close to the rack.

[0027] By adopting the above technical solution, when the box cover needs to be fixed, the first support rod rotates in the direction close to the locking block, the first support rod drives the connecting rod to rotate, and then the connecting rod drives the rack to move vertically upward through the gear, so that the fastening rod slides and is inserted into the fastening groove to fix the box cover and the storage box.

[0028] When the box cover needs to be opened, the locking rod releases the restriction on the first support rod, and the first support rod moves away from the locking block. The rotation of the first support rod drives the connecting rod to rotate, and then the connecting rod drives the rack to move vertically downward through the gear, so that the fastening rod is separated from the fastening groove, thereby releasing the restriction on the box cover.

[0029] Optionally, a handle is fixedly connected to the upper surface of the box cover.

[0030] By adopting the above technical solution, the staff can use the handle to conveniently rotate the box cover to close and open the storage box.

[0031] In the second aspect, the present application provides a method for using a dust sampler, which adopts the following technical solution:

[0032] A method for using a dust sampler comprises the following steps:

[0033] S1. Install the first support rod: pull the clamping plate in a direction away from the locking block, the clamping plate drives the locking rod to move in a direction away from the locking block, rotate the first support rod to a vertical state, and insert the fixing rod into the fixing groove through the fixing hole;

[0034] S2. Take out the dust sampler body: the first support rod rotates to drive the connecting rod to rotate, and the connecting rod drives the rack to move vertically downward through the gear. When the first support rod is in a vertical state, the fastening rod is separated from the fastening groove, and the box cover is rotated to separate the box cover from the storage box, and the dust sampler body is taken out from the storage groove;

[0035] S3. Clamp the dust sampler body: place the dust sampler body on the upper surface of the third clamping rod, rotate the connecting bolt, and move the third clamping rod toward the first clamping rod until the upper surface of the dust sampler body abuts against the first clamping rod, fix the dust sampler body, open the dust sampler body, and perform dust sampling;

[0036] S4. Storing the dust sampler body: When the dust sampling work is completed, close the dust sampler body, loosen the connecting bolts, move the third clamping rod away from the first clamping rod, separate the first clamping rod from the dust sampler body, remove the dust sampler body from the third clamping rod, and put it into the storage slot;

[0037] S5, fixing the first support rod: rotating the box cover until it abuts against the storage box, rotating the first support rod, the bottom of the first support rod abuts against the inclined surface of the locking rod, and the locking rod moves in a direction away from the locking groove. When the first support rod abuts against the bottom of the locking groove, the locking rod rebounds to abut against the locking groove under the action of the spring, thereby fixing the first support rod;

[0038] S6. Carrying the dust sampler body: When the first support rod rotates to a horizontal state, it drives the connecting rod to rotate. The connecting rod drives the rack to move vertically upward through the gear. The fastening rod slides into the fastening groove to fix the box cover and carry the dust sampler body.

[0039] By adopting the above technical solution, when dust sampling is performed, the restriction of the locking rod on the first support rod is released, and the fixing rod fixes the first support rod to the storage box. The first clamping rod and the third clamping rod fix the dust sampler body, thereby improving the stability during dust sampling.

[0040] After the dust sampling work is completed, the restrictions on the dust sampler body by the first clamping rod and the third clamping rod are released, and the dust sampler body is placed in the storage slot, which has the effect of facilitating the storage of the dust sampler body when carrying the dust sampler body.

[0041] The locking rod fixes the first support rod, and at the same time the connecting rod drives the fastening rod to be inserted into the fastening groove through the gear meshing rack transmission to fix the box cover and the storage box, thereby improving the stability when carrying the dust sampler body.

[0042] In summary, the present application includes at least one of the following beneficial technical effects:

[0043] 1. After the dust sampling work is completed, the restrictions of the first clamping rod and the third clamping rod on the dust sampler body are released, and the dust sampler body is stored in the storage box, which has the effect of facilitating the storage of the dust sampler body when carrying it. While the first support rod is fixed by the locking rod, the connecting rod drives the rack to move through the gear, so that the fastening rod is inserted into the fastening groove, and the box cover is fixed to the storage box, thereby improving the stability of the dust sampler body when carrying it.

[0044] 2. When performing dust sampling, the dust sampler body is fixed between the first clamping rod, the third clamping rod and the positioning rod. At the same time, the fixing rod passes through the fixing hole and is inserted into the fixing groove to fix the storage box and the first support rod, thereby improving the stability during dust sampling.

[0053] The following is combined with Figure 2-7 This application is described in further detail.

[0054] An embodiment of the present application discloses a dust sampler.

[0055] like Figure 2 and Figure 3As shown, a dust sampler comprises a dust sampler body 1 and a storage box 3. A storage slot 31 is downwardly opened on the upper surface of the storage box 3. The dust sampler body 1 is placed in the storage slot 31 when not in use. A pair of protrusions 32 are fixedly connected to the upper surface of the storage box 3. A rotating rod 321 is rotatably connected between the two protrusions 32. A box cover 33 is fixedly sleeved on the rotating rod 321. A handle 331 is fixedly connected to the upper surface of the box cover 33 away from the rotating rod 321.

[0056] The side wall of the storage box 3 is rotatably connected with a pair of connecting rods 4, and the connecting rods 4 are parallel to the rotating rods 321. The end of each connecting rod 4 away from the storage box 3 is fixedly sleeved with a first support rod 41, and the first support rod 41 is perpendicular to the connecting rod 4. The end of the first support rod 41 away from the connecting rod 4 is fixedly connected with a second support rod 42.

[0057] A fixing hole 411 is provided inwardly on the side of one of the first support rods 41 away from the storage box 3, and a fixing rod 43 is inserted into the fixing hole 411. A fixing groove 34 is provided on the side of the storage box 3 close to the fixing hole 411. When the first support rod 41 is in a vertical state, the fixing rod 43 passes through the fixing hole 411 and is inserted into the fixing groove 34 to fix the first support rod 41.

[0058] like Figure 2 and Figure 3 As shown, each first support rod 41 is connected to a clamping assembly 5. When the dust sampler body 1 is required for sampling, the dust sampler body 1 is taken out from the storage slot 31, and the dust sampler body 1 is fixed using the clamping assembly 5, and then dust sampling is performed.

[0059] The storage box 3 is provided with a locking assembly 6 on one side of the fixing groove 34. When the dust sampling work is completed, the clamping assembly 5 releases the restriction on the dust sampler body 1 and places the dust sampler body 1 in the storage groove 31 for storage. The fixing rod 43 is moved to the side away from the storage box 3 to separate the fixing rod 43 from the fixing groove 34, and then the first support rod 41 is rotated to a horizontal position, and the locking assembly 6 fixes the first support rod 41.

[0060] When dust sampling is required, the locking assembly 6 is released from the first support rod 41, and the first support rod 41 is rotated to a vertical state. The fixing rod 43 is inserted into the fixing slot 34 through the fixing hole 411, and the first support rod 41 is fixed to the storage box 3.

[0061] Lift the handle 331 upwards, rotate the box cover 33 to the side away from the storage box 3, take out the dust sampler body 1, fix the dust sampler body 1 with the clamping assembly 5, open the dust sampler body 1, and perform dust sampling.

[0062] When the dust sampling work is completed, close the dust sampler body 1, release the restriction of the clamping assembly 5 on the dust sampler body 1, place the dust sampler body 1 in the storage slot 31, and rotate the box cover 33 in the direction close to the storage box 3 until the box cover 33 abuts against the storage box 3.

[0063] Move the fixing rod 43 in a direction away from the fixing slot 34 until the fixing rod 43 is separated from the fixing slot 34, thereby releasing the restriction on the first support rod 41 and the storage box 3, and then rotate the first support rod 41 in a direction close to the locking assembly 6, the first support rod 41 moves to a horizontal position, and the locking assembly 6 fixes the first support rod 41.

[0064] The staff puts the dust sampler body 1 into the storage slot 31 for storage, and uses the first support rod 41 and the second support rod 42 to carry and move the dust sampler body 1, thereby improving the problem that the dust sampler body 1 cannot be stored when being carried.

[0065] like Figure 3 and Figure 4 As shown, the clamping assembly 5 includes a first clamping rod 51, and the first clamping rod 51 is fixedly connected to the first support rod 41. A second clamping rod 53 is fixedly connected to the lower surface of the first clamping rod 51. A connecting hole 52 is downwardly opened on the upper surface of the first clamping rod 51, and a connecting bolt 54 is rotatably connected in the connecting hole 52. The end of the connecting bolt 54 away from the first clamping rod 51 is threadedly connected to a third clamping rod 55.

[0066] An inserting rod 551 is fixedly connected to the upper surface of the third clamping rod 55 , and an inserting groove 531 is opened upward on the lower surface of the second clamping rod 53 . The inserting rod 551 is always slidably inserted in the inserting groove 531 .

[0067] like Figure 2 and Figure 4 As shown, when the dust sampler body 1 needs to be fixed, the dust sampler body 1 is placed between the first clamping rod 51 and the third clamping rod 55, and the lower surface of the dust sampler body 1 abuts against the upper surface of the third clamping rod 55. The staff rotates the connecting bolt 54 to move the third clamping rod 55 to the side close to the first clamping rod 51, and the first clamping rod 51 and the third clamping rod 55 clamp the dust sampler body 1.

[0068] like Figure 3 and Figure 4 As shown, when the dust sampling work is completed, the dust sampler body 1 is closed, the connecting bolt 54 is loosened, the third clamping rod 55 moves away from the first clamping rod 51, and the plug-in rod 551 moves away from the bottom of the plug-in slot 531, thereby releasing the restriction on the dust sampler body 1. The dust sampler body 1 is removed from the third clamping rod 55 and placed in the storage slot 31.

[0069] The upper surface of each third clamping rod 55 is fixedly connected to a positioning rod 552. When the dust sampler body 1 abuts against the upper surface of the third clamping rod 55, the dust sampler body 1 is placed between the two positioning rods 552, reducing the possibility of the dust sampler body 1 sliding on the upper surface of the third clamping rod 55 along the length direction of the third clamping rod 55.

[0070] like Figure 3 and Figure 5 As shown, the locking assembly 6 includes a mounting rod 61 fixedly connected to the outer wall of the storage box 3, and a locking block 62 is fixedly connected to the end of the mounting rod 61 away from the storage box 3. A locking groove 621 is downwardly opened on the upper surface of the locking block 62, and the locking groove 621 passes through the side of the locking block 62 close to the connecting rod 4 and the side away from the connecting rod 4.

[0071] A mounting hole 622 is provided on one side of the locking block 62 away from the mounting rod 61, a locking rod 63 is slidably inserted in the mounting hole 622, a clamping plate 64 is fixedly connected to one end of the locking rod 63 away from the locking block 62, a spring 65 in a tensioned state is fixedly connected between the locking block 62 and the clamping plate 64, and the spring 65 is sleeved with the portion of the locking rod 63 between the locking block 62 and the clamping plate 64. The portion of the locking rod 63 inserted into the locking groove 621 is an inclined surface.

[0072] like Figure 3 and Figure 5 As shown, when the first support rod 41 needs to be fixed, the first support rod 41 is rotated toward the locking block 62, and the first support rod 41 is slidably inserted into the locking groove 621. The bottom of the first support rod 41 first abuts against the inclined surface of the locking rod 63, and the locking rod 63 moves away from the locking block 62 under the action of the first support rod 41.

[0073] After the first support rod 41 abuts against the bottom of the locking groove 621 , the locking rod 63 moves toward the locking block 62 under the elastic force of the spring 65 , passes through the locking block 62 and abuts against the inner wall of the locking groove 621 , thereby fixing the first support rod 41 .

[0074] like Figure 2 and Figure 5 As shown, when the first support rod 41 needs to be released, the clamping plate 64 is moved away from the locking block 62, and then the clamping plate 64 drives the locking rod 63 to move away from the locking block 62, and the locking rod 63 is separated from the locking groove 621, thereby releasing the restriction on the first support rod 41.

[0075] When the first support rod 41 needs to be fixed, the locking rod 63 abuts against the inner wall of the locking groove 621 , and the spring 65 is in a stretched state, which increases the stability of the locking rod 63 abutting against the locking groove 621 .

[0076] At the same time, during the process of inserting the first support rod 41 into the locking groove 621, under the action of the inclined surface, there is no need for the staff to manually separate the locking rod 63 from the locking groove 621. The first support rod 41 can be inserted into the locking groove 621, making the fixing process of the first support rod 41 simpler and more convenient.

[0077] like Figure 2 and Figure 6 As shown, a cavity 35 is opened downward on the upper surface of the storage box 3, one end of a connecting rod 4 passes through the storage box 3 and is placed in the cavity 35, and the connecting rod 4 is connected to a fixing assembly 7, which is arranged in the cavity 35. When the dust sampler body 1 is placed in the storage slot 31, the box cover 33 abuts against the storage box 3, and the fixing assembly 7 fixes the box cover 33.

[0078] The fixing assembly 7 includes a gear 71 fixedly connected to one end of the connecting rod 4 placed in the cavity 35, the gear 71 is meshed with a rack 72, the rack 72 is slidably connected to the vertical inner wall of the cavity 35, and a fastening rod 721 is fixedly connected to the upper surface of the rack 72. When the first support rod 41 is in a vertical state, the fastening rod 721 is placed in the cavity 35.

[0079] like Figure 3 and Figure 7 As shown, a fastening groove 332 is provided on the lower surface of the box cover 33. When the box cover 33 abuts against the upper surface of the storage box 3, the fastening groove 332 is arranged opposite to the fastening rod 721. When the staff rotates the first support rod 41 to a horizontal state, the first support rod 41 drives the connecting rod 4 to rotate, the connecting rod 4 drives the gear 71 to rotate, and the gear 71 drives the rack 72 and the fastening rod 721 to move upward. When the first support rod 41 moves to a horizontal state and is fixed by the locking rod 63, the fastening rod 721 is inserted into the fastening groove 332 to fix the box cover 33, thereby increasing the stability of the box cover 33 when it abuts against the upper surface of the storage box 3.

[0080] like Figure 2 and Figure 6 As shown, when dust sampling is required, the clamping plate 64 is moved away from the locking block 62, and the clamping plate 64 drives the locking rod 63 to move away from the locking block 62. The locking rod 63 is separated from the locking groove 621, and the restriction of the locking rod 63 on the first support rod 41 is released. The first support rod 41 is rotated to the side away from the locking block 62. The rotation of the first support rod 41 drives the connecting rod 4 to rotate, and the rotation of the connecting rod 4 drives the gear 71 to rotate, and then the gear 71 drives the rack 72 to move vertically downward.

[0081] When the first support rod 41 moves to the vertical position, the fastening rod 721 separates from the fastening groove 332, releasing the restriction on the box cover 33, and the box cover 33 is rotated to the side away from the storage box 3, and the dust sampler body 1 is taken out from the storage box 3 to perform dust sampling.

[0082] like Figure 3 and Figure 7 As shown, when the first support rod 41 is inserted into the locking groove 621 and fixed, the rack 72 drives the fastening rod 721 to slide and insert into the fastening groove 332, fixing the box cover 33 and the storage box 3, making it convenient to carry or move the dust sampler body 1.

[0083] The present application also discloses a method for using a dust sampler, such as Figure 2 and Figure 3 As shown, the method of use includes the following steps:

[0084] S1.

[0085] S2. Take out the dust sampler body 1: When the first support rod 41 rotates and drives the connecting rod 4 to rotate, the connecting rod 4 drives the gear 71 to rotate, and then the gear 71 drives the rack 72 to move vertically downward. When the first support rod 41 is in a vertical state, the rack 72 drives the fastening rod 721 to separate from the fastening groove 332, releases the restriction on the box cover 33, lifts the handle 331, rotates the box cover 33 away from the storage box 3, separates the box cover 33 from the storage box 3, and takes out the dust sampler body 1 from the storage groove 31;

[0086] S3. Clamp the dust sampler body 1: abut the lower surface of the dust sampler body 1 against the upper surface of the third clamping rod 55, and abut the side wall of the dust sampler body 1 against the positioning rod 552. Turn the connecting bolt 54, and the third clamping rod 55 moves toward the first clamping rod 51 until the upper surface of the dust sampler body 1 abuts against the first clamping rod 51. Fix the dust sampler body 1 through the first clamping rod 51, the third clamping rod 55 and the positioning rod 552, open the dust sampler body 1, and perform dust sampling;
