Description

Technical Field

[0001] This utility model relates to the technical field of gas sampling devices, specifically to a gas sampler with a clamping function. Background Technology

[0002] Gas sampling is most common in environmental monitoring. It relates to the effects of gases on different media and species, as well as the factors affecting absorption efficiency and analytical results. These factors are of great significance and constitute a crucial step in gas research. Gas sampling equipment is widely used in modern society, primarily for scientific experiments and research analysis.

[0003] Gas samplers require the absorption bottle to be secured during use, but existing gas sampler securing methods are too simplistic and can only be used to place the absorption bottle, which can easily cause the absorption bottle to tilt or fall over, leading to bending of the gas collection tube, affecting the normal operation of the gas sampler, and reducing its practicality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a gas sampler with a clamping function. This solves the problem that existing gas samplers have overly simplistic fixing methods, which can only place the absorption bottle in a simple manner, easily causing the absorption bottle to tilt or fall over, resulting in bending of the gas collection tube, affecting the normal operation of the gas sampler, and reducing its practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gas sampler with clamping function includes a gas sampler body and a tripod bracket at its bottom. A drying bottle is connected to the top of the gas sampler body. Mounting columns are symmetrically arranged on both sides of the gas sampler body. A guide groove is opened on the outer end face of the mounting column. A guide block is slidably arranged in the guide groove. A support plate located outside the guide groove is provided on the guide block. A receiving groove for placing an absorption bottle is opened through the support plate. A bidirectional screw is provided on the bottom end face of the support plate on one side of the receiving groove. A clamping plate with a semi-circular arc structure is screwed to both sides of the bidirectional screw. A sliding rod is provided on the bottom end face of the support plate on the other side of the receiving groove and is slidably connected to the clamping plate.

[0007] Preferably, the absorption bottle and the drying bottle are connected by a gas collecting hose.

[0008] Preferably, a drive threaded hole communicating with the guide groove is provided on the bottom end face of the mounting column, and a drive threaded rod with one end rotatably connected to the guide block is screwed into the drive threaded hole.

[0009] The above technical solution utilizes a drive screw rod to drive the support plate to move the absorption bottle up and down, thereby adjusting the absorption bottle to a height suitable for the gas collection hose, preventing the gas collection hose from bending and ensuring smooth gas sampling.

[0010] Preferably, a first fixing plate is provided on the bottom end face of the bearing plate at one end of the bidirectional screw, and a second fixing plate is provided on the bottom end face of the bearing plate at the other end of the bidirectional screw, which is screwed to the bearing plate.

[0011] By using the above technical solution and the bidirectional screw, the two clamping plates can be moved relative to each other to clamp and fix the bottom of the absorption bottle, thus preventing the absorption bottle from tilting or tipping over.

[0012] Preferably, a damping pad is provided on the inner sidewall of the clamping plate.

[0013] By using the above technical solution and the damping pad, the clamping plate can be prevented from making hard contact with the absorption bottle, thereby improving the safety of clamping and fixing the absorption bottle.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In use, first, align the absorption bottle with the receiving slot on the support plate and insert it to initially fix the absorption bottle onto the gas sampler body. Then, turn the double-ended screw to move the two clamping plates relative to each other, thereby clamping and fixing the bottom of the absorption bottle. Next, connect one end of the gas collecting hose to the drying bottle, and turn the drive threaded rod to move the guide block in the guide groove. The moving guide block moves the support plate accordingly, thereby adjusting the absorption bottle to a height suitable for the gas collecting hose. Finally, connect the other end of the gas collecting hose to the absorption bottle. This invention can clamp and fix the absorption bottle, ensuring its stability during gas sampling. It also allows for adjustment of the absorption bottle to a height suitable for the gas collecting hose, preventing the hose from bending and ensuring smooth gas sampling.

[0023] Example

[0024] This invention provides a gas sampler with a clamping function, see reference. Figure 1-4 As shown, the device includes a gas sampler body 1 and a detachable tripod 2 at its bottom. A drying bottle 3 is connected to the top of the gas sampler body 1. Mounting posts 7 are symmetrically arranged on both sides of the gas sampler body 1. A trapezoidal guide groove 8 is formed on the outer end face of each mounting post 7. A guide block 11 slides within the guide groove 8 and engages with it. The arrangement of the guide block 11 and the guide groove 8 improves the stability of the vertical displacement of the support plate 5. The support plate 5 is located on the guide block 11 outside the guide groove 8. A receiving groove 12 for placing an absorption bottle 6 is provided through the support plate 5. A bidirectional screw 9 is provided on the bottom end face of the support plate 5 on one side of the receiving groove 12. A clamping plate 15 with a semi-circular arc structure is screwed to both sides of the bidirectional screw 9. The two clamping plates 15 are located below the support plate 5. A slide rod 13 is provided on the bottom end face of the support plate 5 on the other side of the receiving groove 12 and is slidably connected to the clamping plate 15. The slide rod 13 is parallel to the bidirectional screw 9. The setting of the slide rod 13 improves the stability of the displacement of the two clamping plates 15 driven by the bidirectional screw 9.

[0025] The absorption bottle 6 and the drying bottle 3 are connected by a gas collecting hose 4.

[0026] The mounting column 7 has a drive threaded hole on its bottom end face that communicates with the guide groove 8. A drive threaded rod 10, one end of which is rotatably connected to the guide block 11, is screwed into the drive threaded hole. By setting the drive threaded rod 10, the bearing plate 5 can be driven to move the absorption bottle 6 up and down, thereby adjusting the absorption bottle 6 to a height that is suitable for the gas collection hose 4, preventing the gas collection hose 4 from bending and ensuring the smoothness of gas sampling.

[0027] The bidirectional screw 9 has a first fixing plate 14 rotatably connected to the bottom end face of the bearing plate 5 at one end, and a second fixing plate screwed to the bottom end face of the bearing plate 5 at the other end. By setting the bidirectional screw 9, the two clamping plates 15 can be operated to move relative to each other, clamping and fixing the bottom of the absorption bottle 6 to prevent the absorption bottle 6 from tilting or tipping over.

[0028] The clamping plate 15 has a damping pad on its inner side wall. The damping pad is made of rubber. The damping pad prevents the clamping plate 15 from making hard contact with the absorption bottle 6, thus improving the safety of clamping and fixing the absorption bottle 6.

[0029] The working principle of this utility model is as follows:

[0030] In use, firstly, align the absorption bottle 6 with the receiving groove 12 on the support plate 5 and insert it to initially fix the absorption bottle 6 onto the gas sampler body 1. Then, turn the bidirectional screw 9 to drive the two clamping plates 15 to move relative to each other, thereby clamping and fixing the bottom of the absorption bottle 6. Next, connect one end of the gas collecting hose 4 to the drying bottle 3, and turn the drive threaded rod 10 to drive the guide block 11 to move within the guide groove 8. The moving guide block 11 drives the support plate 5 to move accordingly, thereby adjusting the absorption bottle 6 to a height suitable for the gas collecting hose 4. Finally, connect the other end of the gas collecting hose 4 to the absorption bottle 6. This utility model can clamp and fix the absorption bottle 6, so that the absorption bottle 6 can remain stable during gas sampling. At the same time, it can adjust the absorption bottle 6 to a height suitable for the gas collecting hose 4, avoiding bending of the gas collecting hose 4 and ensuring smooth gas sampling.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
