Description

Technical Field

[0001] This utility model relates to the field of air pressure testing equipment, and in particular to an adjustable dual-head air pressure gauge. Background Technology

[0002] In the existing field of dual-head barometer technology, when it is necessary to switch between different models of air inlet connectors to adapt to different gas pipelines for pressure testing, it is usually necessary to use tools such as screwdrivers to first remove the original air inlet connector from the gauge base, and then select a suitable air inlet connector and install it onto the gauge base by manually tightening screws. This operation is not only cumbersome, but also consumes a lot of time and effort during disassembly and installation, as it requires precise alignment of the threaded holes and multiple adjustments to the position of the air inlet connector. Especially in testing scenarios that require frequent connector switching, the efficiency is extremely low.

[0003] In the field of dual-head barometer technology, switching the inlet connector is a crucial step in achieving pressure detection adaptation for different gas pipelines. Existing dual-head barometers typically use a threaded connection for inlet connector switching. The specific process involves the operator first preparing tools such as a wrench, then using the wrench to loosen the threads of the existing inlet connector and remove it from the gauge base; next, selecting a connector suitable for the current testing requirements from the container; finally, using the wrench again, screwing the new connector onto the gauge base. After installation, the connector's sealing must be checked multiple times to ensure a secure connection and no gas leakage.

[0004] First, the reliance on tools such as wrenches for disassembly and installation makes the operation cumbersome and complex. Each connector change requires a significant amount of time, especially in work scenarios involving frequent connector changes, severely reducing testing efficiency and greatly impacting overall work progress. Second, existing barometers are equipped with a limited number of inlet connector models, making it difficult to meet the diverse requirements of gas pipeline specifications. This often results in incompatibility when facing different testing tasks, leading to poor versatility and limiting the barometer's applicability to various testing scenarios. Therefore, an adjustable dual-head barometer is proposed to address these issues. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable dual-head pressure gauge, comprising a gauge base, a low-pressure oil gauge, and a high-pressure oil gauge. Both ends of the gauge base are air inlets. The top of the gauge base is threadedly connected to the bottom of the low-pressure oil gauge and the high-pressure oil gauge, respectively.

The end of the air inlet connector passes through the hole wall of the through hole. The air inlet connector is adapted to the air inlet ends of both ends of the meter base. A sealing assembly is provided inside the air inlet end of the meter base.

[0007] As a further description of the above technical solution: the sealing assembly includes an air pump, which is fixedly installed on the front of the gauge base.

[0018] 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.

[0019] Reference Figure 1 , Figure 2 This utility model provides an embodiment of an adjustable dual-head pressure gauge, including a gauge base 1, a low-pressure oil gauge 17, and a high-pressure oil gauge 18. A hook 5 is fixedly connected to the top of the gauge base 1, facilitating the hanging and storage of the pressure gauge, saving space, and making it easy to access. Both ends of the gauge base 1 are air inlets for connecting to different gas pipelines for pressure detection. The top of the gauge base 1 is threadedly connected to the bottom of the low-pressure oil gauge 17 and the high-pressure oil gauge 18, respectively. This threaded connection facilitates the installation and disassembly of the gauges, making subsequent maintenance and replacement convenient. The left end of the gauge base 1... The air inlet of the gauge is connected to the low-pressure oil gauge 17, and the air inlet at the right end of the gauge base 1 is connected to the high-pressure oil gauge 18, so as to realize the simultaneous detection of gases with different pressure ranges. The top edges of the low-pressure oil gauge 17 and the high-pressure oil gauge 18 are respectively hinged with dust covers 4 by pins. The dust covers 4 can be flexibly flipped open and closed. The dust covers 4 are fixedly connected to the inner wall of the gauge with magnetic elements. The magnetic elements are made of permanent magnets or magnetic materials. Through magnetic adsorption, the dust covers 4 are tightly attached to the gauge, effectively preventing dust and debris from entering the inside of the gauge and protecting the oil gauge.

[0020] Reference Figure 3 - Figure 5 The two ends of the instrument base 1 are respectively provided with connector switching components. The connector switching components include mounting sleeves 6. The mounting sleeves 6 provide a mounting base for components such as rotating disk 7 and moving disk 10 to ensure structural stability. The mounting sleeves 6 are fixedly connected to the two ends of the instrument base 1. The inner wall of the mounting sleeve 6 is rotatably connected to the rotating disk 7 through the rotating shaft 9. The rotating shaft 9 enables the rotating disk 7 to rotate flexibly to realize the switching of the air intake connector 8. The center of the end face of the moving disk 10 is fixedly connected to the operating handle 16. The operating handle 16 facilitates the operator to pull and rotate. The moving disk 10 is slidably connected to the inner wall of the rotating disk 7.

[0021] Reference Figure 4 - Figure 6The inner wall of the rotating disk 7 is provided with a sliding groove 11, which provides a sliding track for the slider 13, making the movement of the moving disk 10 more stable. The outer wall of the moving disk 10 is slidably connected to the inner wall of the sliding groove 11 through the slider 13. The end face of the moving disk 10 is elastically connected to the inner wall of the rotating disk 7 through a spring 12. The spring 12 provides elastic force for the reset of the air intake connector 8. One end of the spring 12 is fixedly connected to the inner wall of the sliding groove 11, and the other end of the spring 12 is fixedly connected to the side of the slider 13. An air inlet connector 8 is fixedly connected to the end face of the pressure gauge. The air inlet connector 8 is used to connect gas pipelines of different specifications to achieve multiple detection adaptations of the pressure gauge. The inner wall of the mounting sleeve 6 and the end face of the rotating disk 7 are respectively provided with through holes that are adapted to the air inlet connector 8. The through holes ensure that the air inlet connector 8 can be accurately aligned and connected to the air inlet end of the gauge base 1 after switching. The end of the air inlet connector 8 passes through the hole wall of the through hole. The air inlet connector 8 is adapted to the two air inlet ends of the gauge base 1. A sealing component is provided inside the air inlet end of the gauge base 1.

[0022] Reference Figure 1 , Figure 7 The sealing assembly includes an air pump 2, which provides the power source for inflating the airbag 15. The air pump 2 is fixedly installed on the front of the gauge base 1 for easy operation and control by the operator. The two ends of the air pump 2 are the inflation ends, and the inflation ends of the air pump 2 are fixedly connected to the inflation pipes 3. The inflation pipes 3 are used to transmit gas and connect the air pump 2 and the airbag 15. The inflation pipes 3 are fixedly connected to the outer wall of the gauge base 1 and the airbag 15. The end of the inflation pipes 3 is connected to the inside of the airbag 15. The inner wall of the gauge base 1, which is the air inlet end, is provided with a slot 14. The slot 14 is used to fix the position of the airbag 15 so that it accurately seals the gap between the air inlet connector 8 and the air inlet end of the gauge base 1. The airbag 15 is located on the inner wall of the slot 14. Both the slot 14 and the airbag 15 are annular in shape. The annular design can evenly seal the entire gap between the air inlet connector 8 and the air inlet end of the gauge base 1, ensuring the sealing effect.

[0023] Working principle: When it is necessary to switch between different models of air inlet connectors 8 to adapt to different testing requirements, the operator needs to hold the operating handle 16 and pull it outward. At this time, the operating handle 16 drives the moving disk 10 to slide on the inner wall of the rotating disk 7. The slider 13 on the outer wall of the moving disk 10 slides synchronously along the groove 11 opened on the inner wall of the rotating disk 7. During the sliding process, the slider 13 compresses the spring 12, causing it to deform. This sliding design, through the cooperation of the slider 13 and the groove 11, effectively improves the stability of the movement of the moving disk 10. After the moving disk 10 is pulled out to the appropriate position, the operator... Rotate the operating handle 16, which drives the moving disk 10 to rotate around the rotating shaft 9. The rotating disk 7 is equipped with multiple air inlet connectors 8 of different models. Every 90 degrees of rotation, an air inlet connector 8 will be switched. When the required model of air inlet connector 8 is rotated to overlap with the through hole on the inner wall of the mounting sleeve 6 and the end face of the rotating disk 7, the operator releases the operating handle 16. The spring 12, which is in a compressed state, pushes the slider 13 with its lateral elastic potential energy, thereby driving the moving disk 10 and the air inlet connector 8 to reset, so that the air inlet connector 8 is accurately inserted into the air inlet end of both ends of the base 1.

[0024] After the air inlet connector 8 is plugged in, start the air pump 2, which is fixedly installed on the front of the gauge base 1. The two air inlets of the air pump 2 start working and inflate the air tube 3 and the air bag 15 respectively. Since the air bag 15 is made of rubber, it will gradually expand during the inflation process, filling the gap between the air inlet connector 8 and the two air inlets of the gauge base 1. The tight fit of the expanded air bag 15 achieves the sealing effect after switching the air inlet connector 8, ensuring that there is no gas leakage during the air pressure test and ensuring the accuracy of the test data.

[0025] During air pressure testing, gas enters the gauge base 1 through the installed and sealed air inlet connector 8, and then flows to the low-pressure oil gauge 17 and high-pressure oil gauge 18 connected to it. The oil gauges detect the gas pressure and display the corresponding values. The dust cover 4, which is hinged to the low-pressure oil gauge 17 and high-pressure oil gauge 18 by a pin, can be flipped over to cover the dial when the oil gauge is not in use. The magnetic element of the dust cover 4, which is set at the opposite position to the inner wall of the dial, is made of permanent magnet or magnetic material. It will achieve adsorption connection with the inner wall of the dial through the magnetic field force generated by itself. Under normal operating conditions, this magnetic field force can ensure that the dust cover 4 is tightly attached to the inner wall of the dial and will not fall off, thereby effectively preventing dust and debris from entering the dial, playing a good dust protection role, extending the service life of the oil gauge, ensuring that the oil gauge is always in good working condition, and ensuring the smooth progress of air pressure testing and the reliability of the test results.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
