[0002] With economic development, modern industry has developed rapidly, industrial products have emerged in an endless stream, and various equipment has come into being. Along with industrial production, environmental problems have become increasingly serious. Atmospheric samplers are often used for environmental monitoring. Atmospheric sampling is the process of collecting samples of pollutants or polluted air in the atmosphere. Atmospheric sampling is an important step in atmospheric environmental monitoring and is extremely important for the reliability of monitoring data. Atmospheric samplers usually need to be used with triangular supports during sampling.

[0003] Currently, when connecting atmospheric samplers to tripods, multiple screws are typically used to firmly fix the sampler to the tripod. This not only makes the installation process cumbersome and laborious, but also requires unscrewing multiple screws during subsequent disassembly, making assembly and disassembly very inconvenient. To address this, we have proposed an atmospheric sampler tripod that is easy to disassemble and install. Utility Model Content

[0004] The purpose of this utility model is to provide an atmospheric sampler tripod bracket that is easy to disassemble and install, in order to solve the problem that the current atmospheric samplers are usually fixed to the tripod bracket with multiple screws, which is not only cumbersome and laborious to install, but also requires unscrewing multiple screws during subsequent disassembly, making disassembly and assembly very inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a triangular support for an atmospheric sampler that is easy to disassemble and install, comprising a top plate, connecting seats evenly fixed at the bottom of the top plate, a support foot rotatably mounted inside the connecting seat, a first rotating block fixed on the inner side of the support foot, a connecting rod rotatably mounted on the outer side of the first rotating block, a sliding rod fixed at the bottom center of the top plate, a connecting ring sliding on the outer side of the sliding rod, a second rotating block evenly fixed on the outer side of the connecting ring, a first fastening bolt threaded through the outer wall of the connecting ring, a disassembly mechanism provided at the top of the top plate, and a fine-tuning mechanism provided at the bottom of the support foot.

[0006] Preferably, the disassembly and assembly mechanism includes a mounting bracket fixed to the top of the top plate. A slot is provided through the center of the top of the mounting bracket. Limiting rods are symmetrically fixed at the top between the two sides of the inner cavity of the mounting bracket. Moving plates are symmetrically slidable on the outer side walls of the limiting rods. Insert rods are symmetrically fixed on the inner sides of the two moving plates. A return spring is sleeved on the outer side of the limiting rod. A rack is symmetrically fixed at the bottom of the moving plate. A mounting plate is fixed in the center between the two sides of the inner cavity of the mounting bracket. A rotating shaft is rotatably driven through the center of the top of the mounting plate. A gear is fixed at the top of the rotating shaft. A first knob is fixed at the bottom of the rotating shaft. A second fastening bolt is screwed through the bottom of the first knob. A connecting block is inserted into the slot. Insertion holes are symmetrically provided on one side of the connecting block. A connecting plate is fixed at the top of the connecting block.

[0007] Preferably, the length and width of the slot opening are equal to the length and width of the bottom of the connecting block, which facilitates limiting the connecting block and preventing it from shaking. The end of the reset spring is fixedly connected to one side of the moving plate, which facilitates the resetting of the moving plate.

[0008] Preferably, the second rotating block is rotatably connected to the inside of the connecting rod, and a baffle is fixed at the bottom end of the sliding rod to limit the connecting ring and prevent the connecting ring from detaching.

[0009] Preferably, the gear and the rack are meshed together, so that the rack can be moved when the gear rotates, and the outer side of the first knob is provided with anti-slip texture.

[0010] Preferably, the fine-tuning mechanism includes a storage cavity located in the middle of the bottom of the support foot, mounting cavities symmetrically formed at the bottom of the support foot, a screw connected inside the storage cavity, a second knob screwed onto the outer side of the screw, L-shaped rods symmetrically fixed to the bottom of the outer side wall of the screw, a locking block symmetrically fixed to the top of the second knob, and a locking groove located in the middle of the bottom of the support foot, outside the mounting cavity.

[0011] Preferably, the L-shaped rod is slidably connected to the inside of the mounting cavity, and a limit plate is fixed at the top of the L-shaped rod to limit the screw and make the screw move stably. The locking block is connected to the locking groove to limit the second knob. The outer side of the second knob is also provided with anti-slip texture, and the bottom end of the screw is provided with a pointed tip.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application utilizes a disassembly and assembly mechanism. During assembly, the atmospheric sampler and connecting plate are first assembled using screws. When used in the field, rotating the first knob drives the gear to rotate, causing the rack to move the moving plates away from each other, stretching the return spring. Then, the connecting block is inserted into the slot, and the first knob is loosened. The return spring resets the rod, allowing it to be embedded in the insertion hole, thus completing the fixation. Disassembly only requires rotating the first knob again, thereby avoiding the need to use screws for connection each time during assembly, significantly reducing the complexity of connection, facilitating disassembly and installation, saving time and effort, and improving the practicality of the device.

[0014] 2. In this application, by using the setting of the fine adjustment mechanism, when the ground is uneven, the second knob is rotated to make it rotate. The second knob is screwed to the screw. The screw is limited by the L-shaped rod. When the second knob is rotated, it drives the screw to move, thereby extending the support foot at the lower position and lifting the lower part of the top plate. This makes it easy to adjust according to the terrain, keep the top plate level, and prevent it from affecting the sampling. Attached Figure Description

[0026] In use, the following steps are taken: First, connect the connecting plate 292 to the atmospheric sampler using screws to complete the assembly. When collecting atmospheric data in the field, unfold the tripod support, rotate the first fastening bolt 180 to separate it from the outer wall of the sliding rod 150, release the fixing of the connecting ring 160, move the connecting ring 160 upward, causing the second rotating block 170 to move, causing the connecting rod 140 to deflect, causing the support foot 120 to deflect around the connecting seat 110, open the support foot 120, and then rotate the first fastening bolt 180 in the opposite direction. This ensures the slide bar 150 is pressed against the outside, and the connecting ring 160 is fixed, completing the bracket erection. When the ground is uneven, to ensure the top plate 100 is level, rotate the second knob 340 located at the inclined part of the top plate 100. The second knob 340 is screwed to the screw 330. The L-shaped rod 350 limits the screw 330. When the second knob 340 rotates, it drives the screw 330 to move, thereby extending the lower support foot 120 and lifting the lower part of the top plate 100 to make the top plate 100 level. Then connect the atmospheric sampler to the tripod bracket. Since the air sampler is pre-installed and connected to the connecting plate 292, during installation, the second fastening bolt 280 is rotated to separate it from the bottom of the mounting plate 260. The first knob 272 is then rotated to make the shaft 270 rotate, which in turn drives the gear 271 to rotate clockwise. This causes the rack 250 to move the moving plate 230 away from each other, stretching the return spring 240. Then, the connecting block 290 is inserted into the slot 211, and the first knob 272 is loosened. The return spring 240 then resets the moving plate 230, causing it to move the insertion rod 231. Reset the device so that the insertion rod 231 is embedded in the insertion hole 291 and the connecting block 290 is fixed. Then, rotate the second fastening bolt 280 in the opposite direction so that its end is pressed against the bottom of the mounting plate 260 and the first knob 272 is fixed. When disassembly is required, rotate the second fastening bolt 280 to release the fixation of the first knob 272. Rotate the first knob 272 clockwise so that the moving plate 230 moves the insertion rod 231 away from each other, so that the insertion rod 231 is removed from the insertion hole 291, the fixation of the connecting block 290 is released, and the atmospheric sampler can be disassembled.
