Description

Technical Field

[0001] The utility model relates to the technical field of dust detectors, in particular to a portable dust detector. Background Art

[0002] Dust detector is also called dust meter, dust measuring instrument or dust tester. It is mainly used to detect dust concentration in ambient air. It also has different sizes. The small one is only the size of a palm, and the large one is equivalent to the size of a suitcase. At present, large dust testers have the following problems when performing dust detection on outdoor ambient air: (1) Since large dust testers are relatively bulky, it is not convenient for people to carry them when moving them in outdoor environments in different areas; (2) When the dust meter is carried and transported, there is no protective device on the outside of the dust meter. Since it is a high-precision device, a large collision may easily lead to inaccurate detection results and make maintenance more difficult.

[0003] In the prior art, a patent with publication number CN 218212524 U discloses a portable environmental dust detector, including a protective shell, a limiting column is fixed on the inner side of the protective shell, and a detector body is connected to the outer side of the limiting column, and an adjustment mechanism is arranged above the limiting column to facilitate people to adjust the height of the detector body, so as to facilitate the detector body to test dust at different air layer heights; the adjustment mechanism includes a screw rod threadedly connected to the left and right inner sides of the detector body, and a sprocket mechanism is keyed to the upper side of the two screw rods, a turntable is fixed above the screw rod close to the right side of the limiting column, and a rocker is welded above the turntable. The portable environmental dust detector can realize dust detection at different heights of the ambient air, and the position of the detector body can also be moved. However, this solution mainly moves the detector in a horizontal push manner, which is not suitable for bumpy outdoor roads. In addition, since the joystick for controlling the height of the detector is located above the limit column, if the overall length of the limit column is relatively long, it will affect the height adjustment operation of the operator, and a stepladder may be required for operation. If the height adjustment operation of the limit column is to be met, the maximum height of the limit column needs to be limited, which may make the height adjustment of the detector unable to meet the actual adjustment needs.

[0004] In view of this, it is necessary to design a portable dust detector to solve the above problems. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A portable dust detector, comprising:

[0008] A box body, wherein a first accommodating space with a top opening is arranged in the box body;

[0009] A dust detector is arranged in the first accommodation space, and a gap is left between the dust detector and the box body;

[0010] A buffer component is arranged at the gap so that a buffer zone is formed between the dust detector and the inner wall of the box, and the buffer components arranged on opposite sides of the dust detector also form a clamping structure so that the dust detector and the box are relatively fixed in the horizontal direction;

[0012] The moving assembly is arranged at the bottom of the box body and is used for cooperating with the pull rod structure to move the box body.

[0013] As a further improvement of the present invention, the top of the dust detector is connected to the vertical screw rod through a connecting piece, so that when the driving piece drives the vertical screw rod to rotate, the connecting piece moves up and down along the vertical screw rod to drive the dust detector to move up and down.

[0014] As a further improvement of the utility model, two vertical screw rods are provided, and the two ends of the cross bar are respectively connected to the top ends of the two vertical screw rods.

[0015] As a further improvement of the present invention, the buffer assembly includes a spring with one end fixed to the inner wall of the box body, and the end of the spring close to the dust detector is connected to a baffle abutting against the side wall of the dust detector.

[0036] The dust detector 10 is arranged in the first accommodation space 21, and a gap is left between the surrounding of the dust detector 10 and the box body 20;

[0037] A buffer component is arranged at the gap, so that a buffer zone is formed between the dust detector 10 and the inner wall of the box 20, and the buffer components arranged on opposite sides of the dust detector 10 also form a clamping structure, so that the dust detector 10 and the box 20 remain relatively fixed in the horizontal direction;

[0038] A height adjustment structure is provided on the box body 20 and is used to adjust the height of the dust detector 10 relative to the box body 20, including a vertical screw rod 31 and a driving member provided on the box body 20 for driving the vertical screw rod 31 to rotate; a cross bar 32 is provided at the top of the vertical screw rod 31, so that the vertical screw rod 31 and the cross bar 32 form a pull rod structure that is convenient for moving the box body 20;

[0039] The moving assembly is arranged at the bottom of the box body 20 and is used for cooperating with the pull rod structure to move the box body 20 .

[0040] Specifically, Figure 4 As shown, in the present embodiment, a second accommodating space 22 is further provided in the box body 20, and the second accommodating space 22 is provided on one side of the first accommodating space 21, and the vertical screw rod 31 is provided in the second accommodating space 22 and extends out of the second accommodating space 22 in a vertical upward direction, and is rotatably connected to the top of the second accommodating space 22 through a rotating shaft; the top of the dust detector 10 is connected to the part of the vertical screw rod 31 located outside the second accommodating space 22 through a connecting member, so that when the driving member drives the vertical screw rod 31 to rotate, the connecting member moves up and down along the vertical screw rod 31 to drive the dust detector 10 to move up and down, and then, while the height of the dust detector 10 is adjusted by using the vertical screw rod 31 in cooperation with the connecting member, the vertical screw rod 31 can also be used as a component of the pull rod structure, which is convenient for the operator to move the box body 20.

[0041] Specifically, in this embodiment, the connecting member is a sleeve plate 312, one end of the sleeve plate 312 is sleeved on the vertical screw rod 31 and is threadedly connected to the vertical screw rod 31, and the other end is fixed to the top of the dust detector 10, so that the vertical screw rod 31 rotates to drive the sleeve plate 312 to move up and down, and then drives the dust detector 10 connected to the sleeve plate 312 to move up and down for height adjustment.

[0042] Specifically, two vertical screw rods 31 are provided, and both ends of the cross rod 32 are respectively connected to the tops of the two vertical screw rods 31, so that the vertical screw rods 31 and the cross rod 32 form a pull rod structure that is convenient for moving the box body 20. The operator can pull the box body 20 obliquely by holding the cross rod 32.

[0043] Specifically, in the present embodiment, the bottom end of the vertical screw rod 31 is connected to the box body 20 via a rotating shaft, the top end is connected to the cross bar 32 via a rotating shaft, and a first gear 311 is also provided on the lower part of the vertical screw rod 31 located in the second accommodating space 22; the driving member includes a driving motor 331 arranged in the second accommodating space, the output end of the driving motor 331 is connected to a rotating rod 332, the end of the rotating rod 332 away from the output end of the driving motor 331 is connected to the box body 20 via a rotating shaft, and a second gear 333 meshing with the first gear 311 is installed on the rotating rod 332, and the driving motor 331 drives the rotating rod 332 to rotate, thereby driving the second gear 333 to rotate, thereby causing the first gear 311 meshing with the second gear 333 to rotate, driving the vertical screw rod 31 to rotate. The driving motor 331 is a forward and reverse motor, and the output end of the driving motor 331 is connected to two rotating rods 332 respectively used to drive the two vertical screw rods 31. The driving motor 331 drives the two rotating rods 332 to rotate synchronously, thereby driving the two vertical rotating rods 332 to rotate synchronously and drive the dust detector 10 to move steadily in the vertical direction. In addition, the driving direction of the forward and reverse motors is controlled to adjust the rotation direction of the rotating rod 332, thereby controlling the rise or fall of the dust detector 10 to adjust the height of the dust detector 10 as needed, which is convenient for dust detection in the air at different heights in the environment.

[0044] The top surface of the box body 20 is provided with a control key for controlling the driving motor 331 .

[0045] In other embodiments, the rotating rod 332 can be manually driven to rotate to control the rotation of the rotating rod 332 and drive the vertical screw rod 31 to rotate, so that the rotating rod 332 can extend upward from the second accommodating space 22 and be rotatably connected to the top of the second accommodating space 22 through a rotating shaft. At the same time, a rotating rod is connected to the top of the rotating rod 332, and the rotating rod 332 is driven to rotate by holding the rotating rod, thereby driving the vertical screw rod 31 to rotate.

[0046] Specifically, the mobile assembly includes a plurality of moving wheels 51 arranged on one side of the bottom of the box 20; a plurality of legs 52 are also arranged on the side of the bottom of the box 20 away from the moving wheels 51; in this embodiment, the moving wheels 51 are brake universal wheels, and two are arranged, and the brake universal wheels are arranged on the same side as the vertical screw rod 31, so that the operator can pull the box 20 obliquely by holding the cross bar 32, which is convenient for moving the dust detector 10 in different outdoor environments. Compared with the conventional flat-push moving box 20, the method of pulling the box 20 obliquely is more suitable for outdoor movement on uneven roads. In addition, there are two legs 52, and the arrangement of the legs 52 can make the box 20 stably placed on the ground, which is convenient for maintaining the stability of the box 20 during the detection process.

[0047] Specifically, the buffer assembly includes a spring 41 fixed at one end to the inner wall of the box 20, and the spring 41 is connected to a baffle 42 abutting against the side wall of the dust detector 10 at one end close to the dust detector 10, and the top of the baffle 42 is inclined downward in the direction close to the dust detector 10; the buffer assembly can also be configured as an anti-collision pad 43, and the top of the anti-collision pad 43 is inclined downward in the direction close to the dust detector 10.

[0048] Specifically, it also includes a cover plate 60 covering the opening of the first accommodating space 21 to protect the top of the dust detector 10 when the dust detector 10 is located in the first accommodating space 21 .

[0049] The working principle of the portable dust detector of the utility model is described below:

[0050] When the dust detector 10 needs to be moved, the dust detector 10 is placed in the first accommodating space 21, the cover plate 60 is closed at the top opening of the first accommodating space 21, and the cross bar 32 is held to pull the box body 20 obliquely, so as to facilitate the movement of the dust detector 10 to the area to be detected in the outdoor environment; the anti-collision pad 43 can be used to protect the front and rear ends of the dust detector 10 from collision, and the spring 41 and the baffle 42 can be used to protect the left and right sides of the dust detector 10 from collision, so as to facilitate the movement of the dust detector 10 to the area to be detected in the outdoor environment; While carrying the dust detector 10, it can also provide anti-collision protection for the four sides of the dust detector 10, especially in an outdoor environment with bumpy roads, to avoid damage to the dust detector 10 caused by road bumps, making it easier for people to carry; when it is necessary to adjust the detection height of the dust detector 10, the driving motor 331 drives the rotating rod 332 to rotate, so as to drive the vertical screw rod 31 connected to the rotating rod 332 through gear meshing to rotate, so that the sleeve plate 312 moves up and down along the vertical screw rod 31, thereby adjusting the height of the dust detector 10.

[0051] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
