Description

Technical Field

[0001] This utility model relates to the field of gas appliance technology, and in particular to a gas venting rack. Background Technology

[0002] In industrial production and related fields, there is a significant demand for gas venting and related measurements. With the continuous development of industrial technology, the requirements for accurate measurement of gas composition, flow rate, and other parameters, as well as the stable release of gases, are increasingly stringent. This not only relates to the safety of the production process but also has a significant impact on production efficiency and product quality. Effective gas venting and accurate measurement help to promptly detect anomalies in the production process, ensuring the stable operation of the entire industrial system.

[0003] In the past, two methods were typically used to address gas venting and related measurement issues. One method involved using a simple fixed support structure, where the measuring instrument was directly mounted on a fixed support structure. This structure was relatively simple and low-cost, but lacked flexibility and adjustability. The other method used a traditional frame structure, utilizing the stability of the frame to support the measuring equipment. However, this structure was more cumbersome to assemble and disassemble, requiring more time and manpower.

[0004] However, these existing conventional methods have significant drawbacks. Simple fixed support structures cannot flexibly adjust the position and angle of the measuring components according to actual needs, making them difficult to adapt to different measurement scenarios. Traditional frame structures, on the other hand, are inconvenient to assemble and disassemble, which greatly affects work efficiency when frequent movement or rearrangement of measuring points is required, failing to meet the flexible and ever-changing needs of actual production. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a scattering rack, which aims to improve the problem of inconvenience caused by the inconvenience of assembling and disassembling traditional frame-type scattering racks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a release frame, comprising a frame body and auxiliary measuring components, wherein the frame body includes a support plate, two mounting seats, a central rod, a connecting plate, a limiting seat, an extension mechanism, a support rod, and an unfolding mechanism;

[0017] By adopting the above technical solution, the support plate is screwed to the top of the central rod, which facilitates the installation and disassembly of the support plate; the limiting block is screwed to the bottom of the central rod, which can limit the sliding of the mounting seat on the central rod and ensure the stability of the shed structure.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This application mainly adopts a flexible adjustable frame combined with auxiliary measurement components, which achieves the effect of flexibly adapting to different gas emission and measurement scenarios. The following is a further detailed description of this application.

[0033] Example 1

[0034] The venting rack provided in Embodiment 1 of this application includes a frame and an auxiliary measuring component. The frame and the auxiliary measuring component work together to meet the needs of gas venting and measurement. The adjustable structure of the frame can flexibly adapt to different measurement scenarios, while the auxiliary measuring component can measure parameters such as gas composition and flow rate.

[0035] Specifically, the frame includes a support plate 1, two mounting seats 2, a central rod 3, a connecting plate 4, a limiting seat 5, an extension mechanism, a support rod 6, and a deployment mechanism. The central rod 3 is the core supporting component of the entire frame. It can be made of high-strength metal, such as stainless steel, to ensure sufficient strength to support other components. The top and bottom of the central rod 3 are threaded. Both mounting seats 2 are slidably fitted onto the central rod 3. The mounting seats 2 can be annular structures, made of plastic or metal. Their sliding fit with the central rod 3 allows the mounting seats 2 to move up and down on the central rod 3. Alternatively, mounting seats 2 with sliders can be used to cooperate with slide rails on the central rod 3 to achieve sliding. A smooth surface treatment between the mounting seats 2 and the central rod 3 can reduce friction and ensure smooth sliding.

[0036] Furthermore, in this embodiment, one end of the connecting plate 4 is fixedly connected to the mounting base 2 located above, and the other end is fixedly connected to the limiting seat 5. The connecting plate 4 can be a strip-shaped metal plate, which is fixed to the mounting base 2 and the limiting seat 5 by welding or bolting. The middle part of the limiting seat 5 is slidably sleeved on the central rod 3. The limiting seat 5 can also adopt a ring structure, which plays a certain role in limiting and guiding the movement of the upper mounting base 2, and prevents the central rod 3 from deflecting during use.

[0037] Furthermore, this embodiment has four extension mechanisms, which are spaced around the central rod 3 and installed at intervals on the circumference of the upper mounting base 2. Each extension mechanism is connected to a support rod 6. The extension mechanism includes a first extension plate 7, a first U-shaped clamp 8, a first extension rod 9, and a first clamp 10. The four first extension plates 7 are fixedly installed in a ring at equal intervals on the upper mounting base 2. The first extension plate 7 can be a triangular metal plate, fixed to the mounting base 2 by welding; it can also be a square or other shaped plate, as long as it can achieve the fixing and connection functions. Each first extension plate 7 is hinged to a first U-shaped clamp 8. The hinge can be a pin connection, allowing the first U-shaped clamp 8 to rotate around the first extension plate 7. One end of the first extension rod 9 is fixedly connected to the middle of the first U-shaped clamp 8. The first extension rod 9 can be a cylindrical metal rod, fixed to the first U-shaped clamp 8 by welding or threaded connection. The other end of the first extension rod 9 is fixedly connected to the first clamp 10. The first clamp 10 is arranged around the upper end of the support rod 6. The first clamp 10 can be an adjustable metal clamp, which is fixed to the support rod 6 by tightening bolts. The combination logic of this extension mechanism is that the force is transmitted from the mounting base 2 to the first U-shaped clamp 8 through the first extension plate 7, and then to the first clamp 10 through the first extension rod 9, ultimately realizing the connection and support of the support rod 6, so that the support rod 6 can adjust its position as the mounting base 2 moves.

[0038] Furthermore, this embodiment has four deployment mechanisms, which are spaced around the central rod 3 and installed at intervals on the circumference of the mounting base 2 located below. Each deployment mechanism is connected to a corresponding extension mechanism on the same support rod 6. The deployment mechanism includes a second extension plate 11, a connecting clamp 12, a second U-shaped clamp 13, a second extension rod 21, and a second clamp 22. The four second extension plates 11 are fixedly installed in a ring at equal intervals on the mounting base 2 located below. Each second extension plate 11 is hinged to one end of a connecting clamp 12, and the other end of the connecting clamp 12 forms an extension plate, the end of which is hinged to a second U-shaped clamp 13. One end of the second extension rod 21 is fixedly connected to the middle of the second U-shaped clamp 13. The second extension rod 21 is similar to the first extension rod 9 and is a cylindrical metal rod. The other end of the second extension rod 21 is fixedly connected to the second clamp 22, which is arranged around the middle of the support rod 6. The second clamp 22 is similar in structure and function to the first clamp 10. The unfolding mechanism and the extension mechanism work together to unfold and retract the support rod 6 by sliding the mounting base 2 on the central rod 3, thereby adjusting the structure of the entire frame.

[0039] Furthermore, in this embodiment, the support plate 1 is fixedly mounted on the upper end of the central rod 3, and the support plate 1 is screwed to the top of the central rod 3. A first mounting hole is formed in the middle of the support plate 1, and a second mounting hole is formed on the central rod 3. The first mounting hole and the second mounting hole are arranged coaxially and oppositely. The auxiliary measuring component is detachably mounted on the support plate 1. This detachable connection method facilitates the replacement and maintenance of the auxiliary measuring component. The venting frame also includes a limiting block, which has an internal thread in the middle. The limiting block is screwed to the bottom of the central rod 3 to limit the movement of the lower mounting seat 2.

[0040] Furthermore, the auxiliary measuring components in this embodiment include a base plate 19, a gas pipe 18, a component analyzer 14, a bypass branch pipe 15, a flow valve 16, and a sealing cap 17. The base plate 19 is detachably connected to the support plate 1. A positioning pin 20 is formed on the lower surface of the base plate 19, which is operably inserted into the first mounting hole and the second mounting hole. The base plate 19 can be a square metal plate, connected to the support plate 1 by bolts or clips. The gas pipe 18 is horizontally fixed to the base plate 19. The gas pipe 18 can be a steel pipe or a plastic pipe, fixed to the base plate 19 by clamps or welding. The gas inlet of the component analyzer 14 connects to the middle of the gas pipe 18. The component analyzer 14 is used to analyze the composition of the gas and can be a commercially available gas component analyzer 14. The two ends of the bypass branch pipe 15 are connected to the two ends of the gas pipe 18, and the middle of the bypass branch pipe 15 is connected to the gas inlet of the component analyzer 14. The bypass branch pipe 15 can be made of the same or different material as the gas pipe 18. Flow valves 16 are installed on both sides of the bypass branch pipe 15 of the component analyzer 14. The flow valves 16 are used to control the gas flow rate and can be manual or electric. A pressure gauge or flow meter can be detachably connected to one side of the flow valve 16 so that the gas pressure or flow rate can be measured as needed. There are two sealing caps 17, which are detachably connected to both ends of the gas pipe 18. The sealing caps 17 can be made of rubber or plastic and are connected to the gas pipe 18 by threads or compression fittings.

[0041] The initial installation and use steps of the venting rack in this embodiment are as follows:

[0042] The first step is to screw the limit block to the bottom of the center rod 3 to determine the movement range of the lower mounting base 2.

[0043] The second step is to sequentially mount the two mounting seats 2 and the limiting seat 5 onto the center rod 3, and then connect the connecting plate 4 to the upper mounting seat 2 and the limiting seat 5.

[0044] The third step is to install the extension mechanism and the unfolding mechanism. Install the four extension mechanisms on the circumference of the upper mounting base 2 and the four unfolding mechanisms on the circumference of the lower mounting base 2, and connect them to the corresponding support rods 6 respectively.

[0045] Fourth step, screw the support plate 1 to the top of the center rod 3.

[0046] The fifth step is to insert the base plate 19 of the auxiliary measuring component into the first mounting hole and the second mounting hole through the positioning pin 20, and then connect it to the support plate 1 with bolts or buckles to complete the assembly of the scaffold.

[0047] Step 6: Based on the actual measurement scenario, slide the mounting base 2 below, adjust the unfolding or retracting state of the support rod 6 through the extension mechanism and unfolding mechanism, and lock it with the limit block to make the frame adapt to the scenario.

[0048] Step 7: Connect the gas pipe 18 to the gas source to be measured, open the flow valve 16 to allow the gas to enter the gas pipe 18 and the bypass branch pipe 15, analyze the gas composition using the component analyzer 14, and measure the gas pressure or flow rate using the pressure gauge or flow meter connected to one side of the flow valve 16.

[0049] Step 8: After the measurement is completed, the limit block can be loosened, allowing the mounting base 2 below to slide down and the support rod 6 to retract. The auxiliary measuring components can be removed for maintenance or replacement, or the various components of the frame can be disassembled for storage and transportation.

[0050] The implementation principle of this embodiment is as follows: The venting frame, through the sliding of the mounting seats 2 above and below the central rod 3, drives the extension and unfolding mechanisms to expand and retract the support rod 6, thereby flexibly adjusting the frame structure to adapt to different measurement scenarios. Auxiliary measuring components are mounted on the support plate 1, and through the cooperation of components such as the gas pipe 18, component analyzer 14, bypass branch pipe 15, and flow valve 16, they can measure parameters such as gas composition and flow rate. Compared with existing technologies, this venting frame has the advantages of strong adjustability and convenient assembly and disassembly, greatly improving work efficiency and meeting the flexible and varied needs of actual production.

[0051] Example 2

[0052] The difference between this embodiment and the previous embodiment lies in the different connection methods used in parts of the extension mechanism and the unfolding mechanism. The first extension plate 7 and the first U-shaped clamping plate 8 of the extension mechanism are connected by an elastic hinge, i.e., through a flexible pin. This allows the first U-shaped clamping plate 8 to provide some elastic cushioning when the support rod 6 is subjected to external force, reducing damage to components. The first extension rod 9 is connected to the first U-shaped clamping plate 8 and the first clamp 10 using a quick-connect method, such as a plug-in connection, facilitating quick disassembly and installation when needed. The second extension plate 11 of the unfolding mechanism is connected to the connecting clamping plate 12, and the connecting clamping plate 12 is connected to the second U-shaped clamping plate 13, also using a similar elastic hinge and quick-connect method.

[0053] The usage steps in this embodiment are basically the same as in Embodiment 1, but the operation is more convenient due to the use of a quick connection method when installing and disassembling the extension mechanism and the unfolding mechanism.

[0054] The implementation principle of this embodiment is as follows: by adopting flexible hinges and quick-connection methods, the scaffolding becomes more flexible and durable during use. The flexible hinges can buffer external forces and protect components from damage, while the quick-connection method further improves the efficiency of scaffolding assembly and disassembly, making it more adaptable to the needs of frequent movement and rearrangement of measurement points, representing a further improvement compared to existing technologies.

[0055] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
