Description

Technical Field

[0001] This utility model relates to the field of air detection, and in particular to an easy-to-operate air detection device. Background Technology

[0002] Air quality monitoring equipment is an instrument used to measure and analyze the concentration of various components and related parameters in the air. It can obtain air quality information in real time and accurately, providing data support for people to understand the ambient air conditions, protect health, and conduct relevant environmental management and scientific research. Air quality monitoring equipment can not only be used to detect outdoor air pollution levels, but also to monitor indoor air quality.

[0003] In air quality testing, the correct setup and proper use of air testing equipment are crucial for obtaining accurate and reliable test data. Typically, when using air testing equipment outdoors, operators first set up a tripod to ensure stable and accurate testing, then mount the air testing instrument on top. Outdoor environments are complex and varied, with significant differences in ground conditions, including uneven or slippery surfaces. To ensure the instrument remains stable on such surfaces, operators need to adjust the tripod leg lengths. By adjusting the leg lengths, the tripod can adapt to different ground height differences, keeping the instrument level. Additionally, counterweights are added to the tripod to effectively improve stability and prevent the instrument from swaying due to external factors such as light winds or minor impacts, thus ensuring stability. The accuracy of test results is crucial; however, the situation is different when air quality testing equipment is used indoors. Indoor environments typically have multiple rooms, and testing personnel need to move the equipment between different rooms according to testing needs. This means that the equipment needs to be disassembled and reassembled multiple times. During this process, frequent disassembly and reassembly operations can easily lead to structural loosening due to improper operation, affecting the accuracy and stability of the instrument, and thus causing deviations in the test data. To solve the problems caused by frequent disassembly and reassembly during indoor use, some air quality testing equipment has been improved in design by installing casters at the bottom of the bracket. With the help of casters, testing personnel can easily push the equipment from one room to another without having to perform tedious disassembly and reassembly work each time, effectively reducing the risk of structural loosening caused by disassembly and reassembly and improving testing efficiency.

[0004] Regarding the aforementioned technologies, the inventors discovered that in actual air quality testing operations, testing personnel have to equip themselves with corresponding air quality testing equipment for different indoor and outdoor usage scenarios. While this approach can ensure the smooth progress of the testing work to a certain extent, it brings many disadvantages. On the one hand, equipping two sets of equipment increases the cost of equipment procurement and maintenance. On the other hand, frequent equipment replacement not only increases the workload of operators but also affects the overall efficiency of the testing work. Therefore, developing an air quality testing device that can meet both indoor and outdoor usage needs, has good versatility, and is easy to use has become an important problem that urgently needs to be solved in the current air quality testing field. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide an easy-to-operate air detection device that can be used both indoors and outdoors, while improving the efficiency of detection operations.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing an easy-to-operate air detection device, including: an air detector body and a conical connecting plate connected to its bottom, wherein a tripod mechanism is detachably connected to the bottom of the conical connecting plate, the tripod mechanism includes an assembly plate assembly and a telescopic rod assembly with at least three telescopic rods arranged in a ring array at its bottom, and also includes a guide auxiliary rod assembly connected to the middle of the bottom of the assembly plate assembly;

[0007] The bottom of the guide auxiliary rod assembly is detachably connected to an adjustable movable frame mechanism. The adjustable movable frame mechanism includes an adjusting rod assembly and a movable seat assembly connected to its bottom. The adjusting rod assembly includes a threaded sleeve, and the bottom end of the threaded sleeve is threadedly connected to an adjusting screw. The surface of the threaded sleeve is symmetrically provided with drive handles.

[0008] The bottom of the guide auxiliary rod assembly is connected to a rectangular block with a bottom opening. The inner cavity of the rectangular block is provided with a T-shaped block that is adapted to it. The bottom of the T-shaped block is rotatably connected to the top of the threaded sleeve. Limiting screws are threaded through both sides of the rectangular block. One end of the limiting screw is located at the bottom of the top of the T-shaped block and abuts against the side of the T-shaped block.

[0009] By adopting the above technical solution, the air detector body is used to detect air and obtain relevant data such as air quality; the conical connecting plate serves to connect the air detector body and the tripod mechanism, providing a basic structure for the stable placement of the entire device, and the assembly plate assembly, as the main support structure of the tripod mechanism, provides an installation position for the telescopic rod assembly; the telescopic rod assembly enables the device to remain stably placed in different terrains and environments and adapt to different height requirements, improving the versatility and practicality of the device; the guide auxiliary rod assembly helps to ensure the stability and accuracy of the adjustable moving frame mechanism during the adjustment process, making the structure of the entire device more compact and reasonable; the threaded sleeve is threadedly connected to the adjusting screw, and the overall length of the adjusting rod assembly can be changed by rotating the adjusting screw; this allows adjustment of the height of the moving seat assembly to provide the device with a moving function, facilitating the transfer of the device between different positions, and also acting as a counterweight when not in use, as it is detached from the ground; the rectangular block has an opening at the bottom, providing installation space for the T-shaped block; after adjusting the angle of the adjusting rod assembly, tightening the limit screw one can fix the position of the T-shaped block, preventing accidental rotation of the adjusting rod assembly during use and ensuring the stability of the device.

[0010] In a preferred embodiment, the present invention can be further configured as follows: the assembly plate assembly includes a chassis and at least two connecting rods spaced apart on its top. The bottom of the chassis is provided with a hinge seat matching the number of telescopic rod assemblies. The hinge seat is connected to the top of the telescopic rod assembly via a pin. It also includes a support ring connected to the top of the connecting rod. A clearance gap is formed between the support ring and the chassis. A vertical rod is connected to the middle of the top of the chassis. A hollow screw is fitted onto the surface of the vertical rod. An adjusting plate is connected to the outer circular surface of the bottom end of the hollow screw. The outer circular surface of the adjusting plate is located close to the outer circular surface of the chassis and does not contact the connecting rod. The inner side of the support ring matches the surface of the conical connecting plate. The hollow screw is threadedly connected to the conical connecting plate. When the bottom of the adjusting plate contacts the top of the chassis, the top of the hollow screw is located below the bottom of the support ring.

[0011] By adopting the above technical solution, the chassis provides a stable bottom support platform for the entire tripod mechanism and is hinged to the telescopic rod assembly via a hinged seat. The connecting rod connects the chassis and the support ring, while providing a spatial layout basis for the installation and operation of components such as the hollow screw. A clearance is formed between the support ring and the chassis, providing space for the operation of components such as the hollow screw, ensuring that the adjustment of the hollow screw is not interfered with by other components, facilitating the installation and adjustment of the equipment by the operator. The vertical rod provides a guide structure for the installation and movement of the hollow screw, ensuring the straightness of the hollow screw during up and down movement, and aligning the threads of the hollow screw with the conical connecting plate. This allows for easy adjustment of the height of the conical connecting plate by rotating the hollow screw, thereby adjusting the position of the air detector body to meet different testing needs.

[0012] In a preferred embodiment, the present invention can be further configured as follows: the telescopic rod assembly includes a sleeve and a sliding rod slidably passing through its inner side; a ball joint is connected to the bottom end of the sliding rod; a pad is fitted to the bottom end of the ball joint; a limiting screw is threaded through the bottom end of the sleeve; one end of the limiting screw is in contact with the surface of the sliding rod; after the telescopic rod assembly swings outward toward the guide auxiliary rod assembly, the outer circular surface of the moving seat assembly does not contact the telescopic rod assembly.

[0013] By adopting the above technical solution, the sleeve and the sliding rod slidably inserted inside it constitute a telescopic structure. The sliding of the sliding rod within the sleeve changes the overall length of the telescopic rod assembly. When the sliding rod reaches the appropriate position, tightening the second limiting screw fixes the position of the sliding rod, preventing it from sliding freely within the sleeve. This ensures the stability of the telescopic rod assembly's length and provides reliable support for the air detector body. Under different terrain conditions, the ball joint allows the foot pad to rotate freely within a certain range, ensuring full contact between the foot pad and the ground. This increases the contact area and friction between the equipment and the ground, improving the equipment's stability on various terrains and ensuring the equipment does not easily shake.

[0014] In a preferred embodiment, the present invention can be further configured as follows: the guide auxiliary rod assembly includes a rod body and a sleeve block that is slidably fitted on its surface. The surface of the sleeve block is provided with hinge seats two that match the number of telescopic rod assemblies. A swing rod is rotatably connected to each hinge seat two. A hinge seat three is rotatably connected to the end of the swing rod away from the hinge seat two. The hinge seats three are respectively connected to the corresponding sleeves.

[0015] By adopting the above technical solution, the sleeve slides on the surface of the rod, thereby driving the connected hinge seat and swing rod to move, thus realizing the adjustment of the angle of the telescopic rod assembly and ensuring the consistency and synchronicity of the angle adjustment of each telescopic rod assembly.

[0016] In a preferred embodiment, the present invention can be further configured as follows: the movable seat assembly includes a base, and the outer circular surface of the base has at least three support plates arranged in annular array. The support plates are connected to the base via hinges. The bottom of the support plates is provided with casters, which are respectively arranged away from the center of the support plates. The top end of the support plates near the base is connected with a latch, and the top side of the base near the support plates is provided with a latch lock. The latch locks are mutually locked and engaged with the corresponding latches.

[0017] By adopting the above technical solution, the base bears the weight of the entire air detection equipment and is connected to other components (such as the adjusting rod assembly) to ensure the stability of the overall structure of the equipment.

[0018] Effect: The presence of the base ensures the strength and stability of the mobile base assembly, reliably supporting the equipment and preventing deformation or damage due to uneven force or excessive load, thus providing a guarantee for the movement and stable placement of the equipment.

[0019] The support plate is connected to the base via a hinge and opens and closes around the hinge to allow the entire movable base assembly to be unfolded and stowed. The casters also provide high mobility, allowing operators to easily move the equipment to different testing positions after the telescopic rod assembly is stowed, improving work efficiency. Furthermore, when the support plate is unfolded to the appropriate position, inserting the latch into the latch lock securely fixes the support plate in the unfolded state, ensuring the stability of the equipment during placement. When it is necessary to retract the support plate, simply pull out the latch, allowing the support plate to rotate around the hinge and retract.

[0020] In a preferred embodiment, the present invention can be further configured such that: a plurality of reinforcing ribs are connected to the top of the base, and one end of each reinforcing rib is connected to the bottom end of an adjusting screw.

[0021] By adopting the above technical solution, the reinforcing ribs enhance the structural strength of the base and disperse stress, making the entire moving base assembly more stable so that it is less prone to deformation or damage when facing various loads.

[0022] In summary, this utility model provides at least one of the following beneficial technical effects of an easy-to-operate air detection device:

[0023] 1. By unfolding the support plate and fixing it with a pin lock, and by driving the threaded sleeve to rotate, the overall length of the adjusting rod assembly increases. As the adjusting rod assembly extends, the bottom of the telescopic rod assembly gradually lifts off the ground. At this time, the adjustable mobile frame mechanism takes on the responsibility of supporting the entire equipment. The operator can easily push the equipment to quickly move its position, which significantly improves the mobility and efficiency of the equipment. When working outdoors, the support plate can be bound and fixed with elastic ropes or magic ropes to increase the counterweight of the equipment and improve the stability of the equipment in complex outdoor environments.

[0037] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0038] It should be noted that these figures are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0039] Reference Figure 1-4 This utility model discloses an easy-to-operate air detection device, comprising: an air detector body 1 and a conical connecting plate 2 connected to its bottom. A tripod mechanism 30 is detachably connected to the bottom of the conical connecting plate 2. The tripod mechanism 30 includes an assembly plate assembly 31 and at least three telescopic rod assemblies 32 arranged in a ring at its bottom. It also includes a guide auxiliary rod assembly 33 connected to the center of the bottom of the assembly plate assembly 31. An adjustable movable frame mechanism 40 is detachably connected to the bottom of the guide auxiliary rod assembly 33. The adjustable movable frame mechanism 40 includes an adjusting rod assembly 41 and a connecting rod assembly 32. The bottom movable seat assembly 42 and the adjusting rod assembly 41 include a threaded sleeve 411. The bottom end of the threaded sleeve 411 is threadedly connected to an adjusting screw 412. The surface of the threaded sleeve 411 is symmetrically provided with a drive handle 413. The bottom of the guide auxiliary rod assembly 33 is connected to a rectangular block 5 with a bottom opening. The inner cavity of the rectangular block 5 is provided with a T-shaped block 6 that is adapted to it. The bottom of the T-shaped block 6 is rotatably connected to the top end of the threaded sleeve 411. Limiting screws 7 are threaded through both sides of the rectangular block 5. One end of the limiting screw 7 is located at the bottom of the top end of the T-shaped block 6 and abuts against the side of the T-shaped block 6.

[0040] The telescopic rod assembly 32 adjusts its length by telescopically extending to change the support height and angle of the tripod mechanism 30, adapting to different terrains and testing needs. This allows the assembly plate assembly 31 to work with the conical connecting plate 2, enabling a detachable connection between the air detector body 1 and the tripod mechanism 30. This facilitates quick assembly and disassembly, improving the equipment's flexibility and maintainability. To further optimize the ease of assembly and disassembly of the adjustable mobile frame mechanism 40, the top of the T-block 6 can be designed as a cone shape. When the T-block 6 is inserted into the inner cavity of the rectangular block 5, the conical top acts as a guide, making the insertion process smoother. Subsequently, by tightening the limiting screw 7, one end of the limiting screw 7 tightly abuts against the side of the T-block 6, thus achieving a stable fixation of the T-block 6 and enabling quick assembly and disassembly of the adjustable mobile frame mechanism 40 and the guide auxiliary rod assembly 33. In indoor use scenarios, the operator only needs to rotate the drive handle 413 to rotate the threaded sleeve 411. Since the threaded sleeve 411 and the adjusting screw 41 2. Threaded connection: The top of the threaded sleeve 411 is rotatably connected to the bottom of the guide auxiliary rod assembly 33 via a rotating shaft. The adjusting screw 412 gradually extends out of the threaded sleeve 411, increasing the overall length of the adjusting rod assembly 41. As the adjusting rod assembly 41 extends, the bottom of the telescopic rod assembly 32 gradually lifts off the ground. At this time, the adjustable moving frame mechanism 40 supports the entire equipment, allowing operators to easily push the equipment and quickly move it to a different position, avoiding the heavy labor of manual handling and significantly improving the mobility and efficiency of the equipment. In outdoor environments, the telescopic rod assembly 32 serves as the main support mechanism. Its stable support ensures the equipment remains stable in complex terrain and harsh weather conditions. At the same time, the adjustable moving frame mechanism 40 also acts as a counterweight, further enhancing the stability of the equipment during use by reasonably distributing its weight, reducing equipment shaking caused by external interference, and thus ensuring that the air detector body 1 can accurately and stably acquire detection data.

[0041] The assembly plate assembly 31 includes a base 311 and at least two connecting rods 312 spaced apart on its top. The bottom of the base 311 is provided with hinge seats 313 matching the number of telescopic rod assemblies 32. The hinge seats 313 are connected to the top of the telescopic rod assemblies 32 via pins. It also includes a support ring 314 connected to the top of the connecting rods 312, with a clearance between the support ring 314 and the base 311. A vertical rod 315 is connected to the center of the top of the base 311. A hollow screw 316 is fitted on the surface of the 5. An adjusting plate 317 is connected to the outer circular surface of the bottom end of the hollow screw 316. The outer circular surface of the adjusting plate 317 is set close to the outer circular surface of the base 311 and does not contact the connecting rod 312. The inner side of the support ring 314 matches the surface of the conical connecting plate 2. The hollow screw 316 is threadedly connected to the conical connecting plate 2. When the bottom of the adjusting plate 317 contacts the top of the base 311, the top of the hollow screw 316 is located below the bottom of the support ring 314.

[0042] Preferably, three connecting rods 312 are provided, arranged in a tripod configuration. This creates a clearance while allowing the operator's hand to contact the outer surface of the adjusting plate 317. When the conical connecting plate 2 is located inside the support ring 314 and the hollow screw 316 is restricted by the vertical rod 315, the center of the conical connecting plate 2 and the center of the hollow screw 316 are coaxial. This reduces the complexity of subsequent hole drilling. The operator's hand drives the outer surface of the adjusting plate 317, which in turn drives the hollow screw 316 to rotate, thereby connecting the air detector body 1 and the tripod mechanism 30 and facilitating subsequent disassembly.

[0043] The telescopic rod assembly 32 includes a sleeve 321 and a sliding rod 322 that slides through its inner side. The bottom end of the sliding rod 322 is connected to a ball joint rod 323, and the bottom end of the ball joint rod 323 is fitted with a pad 324. The bottom end of the sleeve 321 is threaded with a limiting screw 325. One end of the limiting screw 325 is in contact with the surface of the sliding rod 322. After the telescopic rod assembly 32 swings outward to the guide auxiliary rod assembly 33, the outer circular surface of the moving seat assembly 42 does not contact the telescopic rod assembly 32. The guide auxiliary rod assembly 33 includes a rod body 331 and a sleeve block 332 that slides through its surface. The surface of the sleeve block 332 is provided with a hinge seat 333 that matches the number of telescopic rod assemblies 32. A swing rod 334 is rotatably connected inside the hinge seat 333. The end of the swing rod 334 away from the hinge seat 333 is rotatably connected to a hinge seat 335. The hinge seat 335 is connected to the corresponding sleeve 321.

[0044] The movable seat assembly 42 includes a base 421, and at least three support plates 422 arranged in a ring on the outer surface of the base 421. The support plates 422 and the base 421 are connected by hinges. The bottom of the support plate 422 is provided with casters 423, which are respectively arranged away from the center of the support plate 422. The top end of the support plate 422 near the top of the base 421 is connected with a latch 424. The top side of the base 421 near the top of the support plate 422 is provided with a latch lock 425, which is mutually limited and inserted with the corresponding latch 424. The top of the base 421 is connected with a number of reinforcing ribs 414, and one end of the reinforcing ribs 414 is connected to the bottom end of the adjusting screw 412.

[0045] The support plate 422 is hinged to the base 421 via a hinge, allowing the support plate 422 to open and close flexibly relative to the base 421. When the equipment is used indoors, the operator can unfold the support plate 422 to a horizontal position. At this time, the latch lock 425 is precisely inserted into the corresponding latch buckle 424. This latch connection method limits and fixes the support plate 422, thus reliably locking the support plate 422 in a horizontal position. This provides a stable foundation for the operator to move the equipment to a different position. The unfolded and fixed support plate 422 increases the distance between the equipment and the ground. The increased contact area of ​​the support plates disperses the weight of the equipment, making it more stable during movement and reducing potential damage caused by shaking or tilting. When working outdoors, the support plates 422 can be folded up and secured with elastic ropes or magic ropes. This not only facilitates the storage and carrying of the equipment but also provides a certain degree of counterweight to the overall equipment. The increased counterweight lowers the center of gravity of the equipment, allowing it to maintain high stability even under adverse conditions such as wind and uneven ground, ensuring the smooth operation of air quality testing.

[0046] The implementation principle of this embodiment is as follows: During use, the tripod mechanism 30 is opened, allowing the three telescopic rod assemblies 32 to unfold naturally. The length of the telescopic rod assemblies 32 is adjusted according to the actual usage scenario and testing requirements. The operator can manually slide the slide rod 322 within the sleeve 321. When the telescopic rod assembly 32 reaches the appropriate length, the second limiting screw 325 is tightened, causing one end to firmly contact the surface of the slide rod 322, thereby fixing the position of the slide rod 322 and ensuring the stability of the length of the telescopic rod assembly 32. Then, T... T-shaped block 6 is inserted into the inner cavity of rectangular block 5, and the limiting screw 7 is tightened. Through the tightening action of the limiting screw 7, T-shaped block 6 and rectangular block 5 are firmly connected, completing the assembly of the lower adjustable movable frame mechanism 40. If air testing is performed indoors, the support plate 422 is unfolded to a horizontal state through the hinge, and then the latch 425 is accurately inserted into the corresponding latch buckle 424. The support plate 422 is limited and fixed by the latch connection. Then, with the help of the conical connecting plate 2, the air detector is installed. The air detector body 1 sits stably on top of the assembly plate assembly 31. The operator manually drives the outer surface of the adjusting plate 317, causing the hollow screw 316 to rotate. As the hollow screw 316 rotates, the air detector body 1 is installed on the assembly plate assembly 31 through the threaded engagement. When the equipment needs to be moved, the operator rotates the drive handle 413. The rotation of the drive handle 413 causes the threaded sleeve 411 to rotate synchronously, gradually increasing the overall length of the adjusting rod assembly 41. As the adjusting rod assembly 41 extends, the bottom of the telescopic rod assembly 32 gradually lifts off the ground. At this time, the adjustable moving frame mechanism 40 supports the weight of the entire equipment, allowing the operator to easily push the equipment and move it quickly and smoothly. If air testing is performed outdoors, elastic ropes or magic ropes are used to bind and fix the retracted support plate 422 to increase the equipment's counterweight. By increasing the counterweight, the center of gravity of the equipment is lowered, improving the stability of the equipment in complex outdoor environments and ensuring that air testing can be carried out smoothly.
