[0002] The quality of the indoor environment is closely related to human health. Therefore, environmental protection has been increasingly valued by people. With the continuous attention to air quality, the requirements for the detection of particulate matter in the air are also increasing.

[0003] The utility model patent with the publication number of CN 212410380 U discloses a particulate matter detection device for indoor environment in construction engineering, including a detector body. A display screen and a signal transmitter are arranged on the right side wall of the detector body. A rotating rod is arranged on the left side of the detector body, and an adjusting mechanism and a clamping mechanism are arranged on the rotating rod. An adsorption mechanism is also arranged on the left side wall of the detector body. The adjusting mechanism includes a fixed rod. A kidney-shaped hole matching the fixed rod is opened on the side wall of the rotating rod. The fixed rod is arranged in the kidney-shaped hole, and both ends of the fixed rod are fixedly connected with fixing blocks, and the side walls of the fixing blocks are fixedly connected with the side wall of the detector body. The clamping mechanism includes two arc-shaped clamping plates and a torsion spring. A through groove is opened at the top of the rotating rod.

[0004] This utility model can facilitate the fixation of the detector body, so that it is not necessary to hold it by hand for detection, which is convenient for people to use.

[0005] However, there are still some disadvantages in the actual use of the above device. The more obvious one is that when using the arc-shaped clamping plates to fix the device on a round rod, the operator first needs to slide the rotating rod upward along the fixed rod, then rotate the rotating rod, and finally pull the handle to make the two arc-shaped clamping plates open to both sides to achieve the clamping operation. The operation is too cumbersome, and the above operation needs to be repeated when releasing the fixation later, which further increases the operation difficulty and is too inconvenient in actual use.

[0006] Therefore, it is very necessary to invent a particulate matter detection device for indoor environment to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide a particulate matter detection device for indoor environment to solve the problems raised in the above background technique.

[0014] The technical effects and advantages of the present utility model:

[0015] By providing a convenient clamping mechanism, when it is necessary to fix the device on the outer side of a certain round rod during the detection process, an operator holds the U-shaped back plate with one hand and pushes the holding mechanism upward with the other hand. After the holding mechanism is pushed, the sliding rod moves upward. When the sliding rod moves upward, the return spring is compressed through the outer sleeve ring, and at the same time, the movable clamping plate is driven to separate from the top of the fixed clamping plate. Then, the device is moved so that the round rod is located between the fixed clamping plate and the movable clamping plate. Then, the holding mechanism is released, and then the compressed return spring drives the movable clamping plate to move downward and reset through the outer sleeve ring and the sliding rod, thereby completing the clamping operation. Compared with the same type of devices in the prior art, the present utility model can more conveniently fix the device on the outer side of the round rod, is simple to operate, can effectively save manpower, and thus improves the use convenience.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] The present invention provides a Figures 1 - 3 kind of indoor environment particulate matter detection device as shown, including a detector body 1. A U-shaped back plate 2 is fixedly sleeved at the rear side of the detector body 1. A convenient clamping mechanism 3 is jointly arranged on the top of the detector body 1 and the U-shaped back plate 2. A holding mechanism 4 is arranged at the bottom end of the convenient clamping mechanism 3.

[0022] As Figure 2 shown in Figure 3 the figure, the convenient clamping mechanism 3 includes a fixed clamping plate 31, a movable clamping plate 32, a sliding rod 33, an outer sleeve ring 34 and a return spring 35. Among them, the fixed clamping plate 31 is fixedly arranged on the top of the detector body 1. The movable clamping plate 32 is attached to the top of the fixed clamping plate 31. Two sliding rods 33, outer sleeve rings 34 and return springs 35 are provided. The two sliding rods 33 are respectively slidably penetrated through both sides of the bottom of the U-shaped back plate 2. The sliding rod 33 slidably penetrates through the fixed clamping plate 31 and is fixedly connected to the movable clamping plate 32. The outer sleeve ring 34 is fixedly sleeved on the outer side of the adjacent sliding rod 33. The return spring 35 is sleeved on the outer side of the sliding rod 33 and is fixedly connected between the U-shaped back plate 2 and the adjacent outer sleeve ring 34.

[0023] By setting the above structure, when the sliding rod 33 moves upward, the return spring 35 can be compressed through the outer sleeve ring 34. At the same time, the movable clamping plate 32 is driven to separate from the top of the fixed clamping plate 31. Then, the device is moved so that the round rod member is located between the fixed clamping plate 31 and the movable clamping plate 32. Then, the holding mechanism 4 is released. Subsequently, the compressed return spring 35 drives the movable clamping plate 32 to move downward and reset through the outer sleeve ring 34 and the sliding rod 33, thereby completing the clamping operation. Compared with the same type of devices in the prior art, the device can be more conveniently fixed on the outer side of the round rod member. While the operation is simple, it can effectively save manpower, thereby improving the use convenience.

[0024] As Figure 3As shown in the figure, the holding mechanism 4 includes a handle 41, an insulating rubber sleeve 42, and an annular anti-slip groove 43. Among them, the handle 41 is fixedly arranged at the bottom ends of two sliding rods 33, the insulating rubber sleeve 42 is fixedly sleeved outside the handle 41, and the annular anti-slip groove 43 is formed on the surface of the insulating rubber sleeve 42.

[0025] By setting the above structure, when it is necessary to fix the device outside a certain round rod during the detection process, an operator can hold the U-shaped back plate 2 with one hand and push the holding mechanism 4 upward with the other hand. After the holding mechanism 4 is pushed, it drives the sliding rod 33 to move upward. At the same time, during the movement of the device, the operator can move the device by holding the insulating rubber sleeve 42.

[0026] It should also be noted that four suction cups are provided at the rear side of the detector body 1, and the four suction cups are respectively fixedly arranged at the four corners of the rear side of the detector body 1.

[0027] By setting the above structure, the detector body 1 can also be fixed on the mirror surface through the suction cups, thereby increasing the fixing diversity of the detector body 1.

[0028] The working principle of the present utility model:

[0029] During the actual use process, when it is necessary to fix the device outside a certain round rod during the detection process, an operator holds the U-shaped back plate 2 with one hand and pushes the holding mechanism 4 upward with the other hand. After the holding mechanism 4 is pushed, it drives the sliding rod 33 to move upward. When the sliding rod 33 moves upward, it compresses the return spring 35 through the outer sleeve ring 34, and at the same time drives the moving clamping plate 32 to separate from the top of the fixed clamping plate 31. Subsequently, the device is moved so that the round rod is located between the fixed clamping plate 31 and the moving clamping plate 32. Then, the holding mechanism 4 is released, and the compressed return spring 35 drives the moving clamping plate 32 to move downward and reset through the outer sleeve ring 34 and the sliding rod 33, thereby completing the clamping operation;

[0030] After the detection is completed, push the holding mechanism 4 upward to make the moving clamping plate 32 separate from the top of the fixed clamping plate 31 to release the clamping of the round rod, and then hold the insulating rubber sleeve 42 to move the device.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
