Its main purpose is to evaluate whether there is a possibility that the workers will suffer from occupational diseases in the workplace, so as to take corresponding measures for prevention and control. When detecting the dust content in the workplace, it is generally detected by a laser dust detector.

[0003] However, the existing detectors have the following problems: the display screen of the detector is generally exposed outside. When carried or placed in a container, it is easy to rub against objects. After long-term use, the display screen will be scratched, affecting the observation of the detection value. And the detector is generally held by hand, which is not convenient for carrying and placing. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages that in the prior art, the display screen of the detector is generally exposed outside. When carried or placed in a container, it is easy to rub against objects. After long-term use, the display screen will be scratched, affecting the observation of the detection value. And the detector is generally held by hand, which is not convenient for carrying and placing, and to propose a laser dust detection device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A laser dust detection device, including a detector body. A display screen and control buttons are arranged at the top of the detector body. A connection hole for connecting a circuit is opened at the bottom of the detector body. A plurality of grooves for conveniently holding the detector body are opened on both sides of the detector body. The edges of the plurality of grooves are all arc-shaped, and the four sides of the detector body are arc-shaped;

[0007] A shielding mechanism, which is arranged on the top of the detector body to shield the display screen;

[0008] A clamping mechanism, which is arranged at the bottom of the detector body to facilitate the carrying and placing of the detector body.

[0009] In a possible design, the shielding mechanism includes a top plate, an observation window, two rotating rods, two snap rings, and two cylinders. The top plate is disposed on the top of the display screen of the detector body. The observation window is arranged on the top plate. An acrylic plate for facilitating the observation of the display screen is arranged inside the observation window. Both ends of the two rotating rods are rotatably connected with a first block, and one sides of the four first blocks are respectively fixedly connected to both sides of the same top plate. The shapes of the two snap rings are both set to be U-shaped. The two ends of the two snap rings are respectively fixedly sleeved on the two rotating rods. One ends of the two cylinders are respectively fixedly connected to both sides of the same detector body, and the two snap rings are respectively sleeved on the two cylinders.

[0010] In a possible design, the clamping mechanism includes a clamping plate, two springs, two connecting plates, a rotating block, and a connecting column. The outer side of the connecting column is respectively fixedly connected to the bottoms of the two connecting plates. The tops of the two connecting plates are both fixedly connected to the bottom of the same detector body. The rotating block is rotatably sleeved on the connecting column. The bottom of the rotating block is fixedly connected to the top of the clamping plate. One ends of the two springs are both fixedly connected to the top of the same clamping plate, and the other ends of the two springs are both fixedly connected to the bottom of the same detector body.

[0011] In a possible design, a baffle for shielding the springs is fixedly connected to the top of the clamping plate. The baffle is located on one side of the springs. A soft pad for reducing collision damage is fixedly arranged on the top of the baffle.

[0012] In a possible design, a plurality of anti-slip strips for facilitating the clamping of the device and an object are arranged on one side of the top and one side of the bottom of the clamping plate.

[0013] In a possible design, a handle for facilitating the holding of the device is fixedly connected to the top of the detector body.

[0014] In this application, when in use, hold it by hand and connect the detector body to the circuit through the connection hole. The device works through a built-in laser dust sensor. When the device is started, the laser beam irradiates the surrounding air, and dust particles will cause the laser to scatter. The scattered light signals at different angles are collected by a detector inside the instrument and converted into electrical signals. The signal processor inside the instrument amplifies, filters, integrates, and analyzes the electrical signals to obtain the dust concentration and particle size distribution data, and displays the corresponding data on the display screen. A top plate with an acrylic plate is set on the display screen and covers above the display screen to play a role in dust prevention and scratch prevention. The acrylic plate set on the observation window allows the user to observe the display screen through the acrylic plate, and then observe the detection data. The combination of the snap ring and the cylinder is used to fix the top plate and is also convenient for disassembling and replacing the top plate. When the device needs to be carried or placed, the staff can manually press one side of the clamping plate, and through the cooperation of the rotating block and the spring, the other side of the clamping plate is opened, and the device is clamped on an external object, which is convenient for carrying and placing the detector body. The spring provides the clamping force to ensure that the device is firmly fixed on the target object. When clamping, the spring can be blocked by the baffle to prevent clothes or other items from winding around the spring. Additionally, anti-slip strips can be set on the clamping plate to increase friction and ensure the stability of the detector body.

[0015] The beneficial effects of the present utility model are as follows:

[0016] In the present utility model, through the clamping mechanism and the shielding mechanism, it effectively prevents the display screen from being damaged by external factors such as dust and scratches when not in use, extends the service life of the device, and can conveniently clamp the device at positions such as brackets and workbenches without additional fixing tools, improving the portability and use flexibility of the device.
