It can extract specific gas samples from the air, measure the concentration of harmful gases such as volatile organic compounds and carbon monoxide in real time or periodically, and record the data for subsequent analysis. This device is widely used in industrial and laboratory places to help identify potential health risks and ensure compliance with occupational safety and health standards.

[0003] The gas sampler is carried to the designated location by holding the handle. Since the sampler has a certain weight and the handle is fixed to the sampler, when the sampler shakes during transportation, the staff needs to exert more force to control the sampler, which increases the user's fatigue. Utility Model Content

[0004] The purpose of the present utility model is to provide a gas sampler for regular occupational health testing, so as to solve the problem proposed in the above-mentioned background technology that the gas sampler is carried to a specified position by gripping the handle. Since the sampler has a certain weight and the handle is fixed to the sampler, when the sampler shakes during transportation, the staff needs to exert more force to control the sampler, which increases the user's fatigue.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A gas sampler for regular occupational health inspection, comprising a main body, a sampling head is installed at the upper end of the main body at a left position, a plurality of fixing columns are fixed at the upper end of the main body at the left position, a fixing ring is fixed at the upper end of the plurality of fixing columns, a fixing plate is fixed at the left and right end positions of the main body, a fixing circular plate is fixed at the inner position of the fixing plate, a rubber rod is fixed at the inner position of the fixed circular plate, a handle is sleeved at the outer wall position of the rubber rod, a sleeve ball sleeved at the inner position of the handle is fitted with the fixed circular plate, a stainless steel spring is fixed at the upper end position of the handle, a button is fixed at the upper end position of the stainless steel spring, the button can push the connecting rod fixed at the lower end position to move, and the connecting rod causes the rubber block at the lower end position to move.

[0006] Preferably, the main body is supported by fixed bases fixed at the four corners of the lower end.

[0007] Preferably, a rear cover is installed on the upper end of the main body at the right side.

[0008] Preferably, a touch screen is provided at the upper left end of the main body.

[0009] Preferably, the main body collects surrounding gas through a sampling head at the upper end.

[0010] Preferably, the handle is sleeved on the outer wall of the fixed circular plate and can be rotated, and the rotation of the handle causes the sleeved ball to move in contact with the outer wall of the fixed circular plate.

[0011] Preferably, pressing the button downwards can cause the rubber block to touch the rubber rod.

[0012] Preferably, the rubber block touches the rubber rod so that the handle cannot rotate.

[0013] Compared with the prior art, the present invention provides a gas sampler for regular occupational health testing, which has the following beneficial effects:

[0014] When the device is used to transport and move the main body, the staff can hold the handle tightly to carry the main body. When the main body shakes back and forth during transportation, the handle is sleeved on the outer wall of the fixed circular plate, and when the main body shakes, the fixed circular plate rotates at the inner side of the handle. In this way, when the staff hold the handle tightly to move the main body, the shaking of the main body can greatly reduce the impact on the staff, thereby reducing fatigue during transportation.

[0015] After the main body is transported to the designated location, the staff can press the button. Pressing the button causes the connecting rod to push the rubber block downward. The rubber block moves downward and fits tightly with the rubber rod. Due to friction resistance, the staff can place the main body stably on the ground.

[0016] Since the weight of the sampling head is concentrated at the top and the diameter of the bottom is too narrow, the sampling head is prone to tilting, causing damage to the connection. In this device, a fixing ring is sleeved on the outer wall of the sampling head. The fixing ring increases the stability of the sampling head, and the fixing ring is supported by the fixing column at the bottom. BRIEF DESCRIPTION OF THE DRAWINGS
