[0002] With the continuous development of air sampling technology and the continuous expansion of application fields, the requirements for air sampling devices are also getting higher and higher. Traditional air sampling devices often have problems such as single function and poor adaptability, and it is difficult to meet the complex and changeable sampling requirements. For example, some devices cannot be adjusted according to the conditions of different ground surfaces, resulting in easy tipping when used on uneven ground; some devices lack the function of air pressure detection and cannot monitor the air pressure inside the gas collection tank in real time, bringing potential safety hazards to the sampling process.

[0003] Furthermore, in existing air sampling devices, the connection between the gas collection tank and the air extraction pump often adopts complex bolt fixation or welding methods, which not only increases the installation difficulty and time cost, but also may cause loosening or damage at the connection part during long-term use, affecting the stability and safety of the device. In addition, although some simple connection methods are convenient for installation, they often cannot provide sufficient stability and are prone to accidental detachment or tipping during the sampling process, bringing inconvenience and risks to the use. Therefore, we provide an air sampling device which is convenient to install. Content of the Utility Model

[0022] In order to more clearly and completely illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the accompanying drawings.

[0023] Embodiment

[0024] As Figures 1-5 shown, an air sampling device that is easy to install proposed by an embodiment of the present utility model mainly includes a gas collecting tank 1, an air pump 2, a suction pipe 3, a grooved block 4, an insertion block 5, a limiting jack 6, and a limiting mechanism 7. Among them, the gas collecting tank 1 serves as a container for collecting sampled gas, and the air pump 2 is responsible for sucking external air into the gas collecting tank 1 through the suction pipe 3. In order to achieve a stable connection between the two, a combined structure of the grooved block 4, the insertion block 5, and the limiting mechanism 7 is specifically designed.

[0025] Among them, two opposite groove blocks 4 are fixedly installed on the top surface of the gas collecting tank 1. These two groove blocks 4 are designed to cooperate with the insertion block 5 at the lower end of the air extraction pump 2; the lower end surface of the air extraction pump 2 is fixedly connected with an insertion block 5. The shape and size of the insertion block 5 match the space in the groove block 4 to ensure a tight fit during insertion. A limiting jack 6 is also horizontally penetrated on the insertion block 5 for subsequent cooperation with the limiting rod 74 in the limiting mechanism 7 to achieve further fixation; the limiting mechanism 7 is composed of a lapping plate 71, an insertion rod 72, a connecting plate 73, and a limiting rod 74. The lapping plate 71 is fixedly connected between the two groove blocks 4 to form a support structure spanning the two; the insertion rod 72 is inserted on the lapping plate 71. One end of the insertion rod 72 is fixedly connected with a connecting plate 73, and the connecting plate 73 is used to install the limiting rod 74; the limiting rod 74 is fixedly connected to the connecting plate 73, and its length and position are designed to be able to accurately dock with the limiting jack 6 on the insertion block 5. After the insertion block 5 is inserted into the groove block 4, by adjusting the position of the insertion rod 72, the limiting rod 74 passes through the through hole 8 and is inserted into the limiting jack 6, thereby realizing a firm connection between the gas collecting tank 1 and the air extraction pump 2; a through hole 8 is horizontally penetrated at the end of the groove block 4. This through hole 8 serves as a passage for the limiting rod 74 to pass through, ensuring that the limiting rod 74 can be smoothly inserted into the limiting jack 6 to complete the installation process.

[0026] Further, support legs 11 are fixedly installed on the lower surface of the gas collecting tank 1. These support legs 11 not only enhance the stability of the gas collecting tank 1 but also enable the entire device to be placed stably on the ground. The lower end of the support leg 11 is designed with a threaded interface for threaded connection with the threaded rod 12. The lower end of the threaded rod 12 is fixedly connected with a rubber cushion block 13. The rubber cushion block 13 has good elasticity and anti-slip performance, which can further increase the friction between the device and the ground and prevent the device from sliding or tipping during use.

[0027] Among them, a gas sampling pipe 9 is installed through the upper surface of the gas collecting tank 1. The gas sampling pipe 9 is used to introduce external air into the gas collecting tank 1. A sealing cap 10 is sleeved at the end of the gas sampling pipe 9. When sampling is not required, the gas sampling pipe 9 can be sealed through the sealing cap 10 to prevent the gas in the gas collecting tank 1 from leaking. In addition, a pressure detection component 14 is fixedly installed on the upper surface of the gas collecting tank 1. The pressure detection component 14 can monitor the internal pressure of the gas collecting tank 1 in real time to ensure the pressure stability and safety during the sampling process.

[0028] Further, in addition to the original lapping plate 71, inserting rod 72, connecting plate 73 and limiting inserting rod 74, the limiting mechanism 7 is also sleeved with a spring 75. One end of the spring 75 is fixedly connected to the surface of the lapping plate 71, and the other end is fixedly connected to the surface of the limiting disc 76. The limiting disc 76 is fixedly connected to the other end of the inserting rod 72 for limiting the excessive movement of the inserting rod 72. In addition, a pulling handle 77 is fixedly connected to the surface of the connecting plate 73, facilitating the user to operate the inserting rod 72 and the limiting inserting rod 74 by pulling the pulling handle 77, so as to realize the quick installation and disassembly between the air collecting tank 1 and the air pump 2.

[0029] Wherein, the inserting block 5 is inserted into the inner wall of the groove block 4. After the inserting block 5 is initially in contact with the groove block 4, by adjusting the position of the inserting rod 72 in the limiting mechanism 7, the limiting inserting rod 74 respectively passes through the through hole 8 and the limiting insertion hole 6. The insertion of the limiting inserting rod 74 not only realizes the physical connection between the air collecting tank 1 and the air pump 2, but also prevents the relative movement or detachment between the two through its limiting effect, thereby ensuring the stability and safety of the device.
