Description
Technical Field
[0001] The utility model relates to the technical field of pipeline air tightness detectors, in particular to a pipeline air tightness detector for preventing gas leakage. Background Art
[0002] Pipeline air tightness detectors are mainly used to detect the waterproof sealing of pipelines or other similar structural products to ensure that the objects being tested do not have water or air leakage defects. Pipeline air tightness detectors are mainly common in industrial manufacturing, energy industry, chemical industry and medical industry. Existing pipeline air tightness detectors still have certain defects when used.
[0003] In the prior art, a pipeline air tightness detector uses an instrument to input compressed air with precise pressure control into the pipeline or product to be tested, and then closes the inflation air source to perform air tightness detection on the pipeline. During use, the pipeline air tightness detector is usually performed by directly plugging the two ends of the test pipeline into the outside of the pipeline joint before testing. This plug-in method is prone to air leakage between the pipeline joint and the test pipeline, resulting in poor sealing and easily leading to abnormal test results. Utility Model Content
[0004] The purpose of the utility model is to provide a gas leakage-proof pipeline air tightness detector to solve the problem of poor sealing performance of pipeline joints of pipeline air tightness detectors on the current market raised in the above background art.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gas leak-proof pipeline air tightness detector, comprising: a detector host, a display screen, a control button, a connecting plate and a pipeline joint, the front of the detector host is respectively equipped with a display screen and a control button, the back of the detector host is connected to a connecting plate through an inflation tube, the front of the connecting plate is equipped with a pipeline joint, a fixed block is installed on the front of the connecting plate near the pipeline joint, the outer side of the fixed block is connected to a connecting ring, the front of the connecting ring is connected to a connecting block, the interior of the fixed block is connected to a first spring, one end of the first spring is connected to a slide plate, the end of the slide plate is connected to a bidirectional arc block, the outer side of the fixed block is slidably connected to a sliding sleeve, the outer side of the sliding sleeve is connected to a slider, and a second spring is connected between the sliding sleeve and the connecting ring.
[0006] Preferably, a sliding structure is formed between the slider and the connecting block, and the connecting block is L-shaped.
[0007] Preferably, a sliding structure is formed between the bidirectional arc block and the fixed block.
[0008] Preferably, a mounting block is installed on the top of the detector host, and a storage box is provided on the top of the mounting block.
[0009] Preferably, the bottom of the storage box is connected to a docking block, and the internal thread of the docking block is connected to a threaded knob.
[0010] Preferably, an elastic band is connected to the outside of the storage box, an end of the elastic band is connected to a hook, and a limit block is installed on the outside of the storage box.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: when the sliding sleeve of the gas leakage-proof pipeline air tightness detector moves, it can drive the slider to move, and when the slider moves, it can slide through the connecting block, and when the sliding sleeve moves, it can compress the second spring, and the elastic belt can limit and fix the connecting plate and the inflation tube inside the storage box. At this time, the elastic belt is not easy to loosen, and the storage box can make the pipeline air tightness detector less likely to fall off during the process of moving the position, and at the same time, the connecting plate and the inflation tube can be neatly stored and placed.
[0012] 1. A pipeline air tightness detector is an instrument for testing the air tightness of pipelines or other similar structures. Since the test pipeline is directly plugged into the outside of the pipeline joint, this plug-in method is not stable enough and is prone to gas leakage. When the sliding sleeve moves, it can drive the slider to move. When the slider moves, it can slide through the connecting block. When the sliding sleeve moves, it can compress the second spring. When the second spring is compressed to the maximum extent, the end of the test pipeline can be plugged into the outside of the pipeline joint. When the sliding sleeve is released, it can be reset by the second spring. When the sliding sleeve is reset, its inner wall can squeeze the curved surface of one end of the bidirectional arc block. When the bidirectional arc block is squeezed, it can drive the slide to move. When the slide moves, it can stretch the first spring. When the curved surface of the other end of the bidirectional arc block moves to the outer surface of the test pipeline, the bidirectional arc block can squeeze and fix the test pipeline. By squeezing and fixing the test pipeline, the sealing between the test pipeline and the pipeline joint is improved, making the test pipeline less likely to leak gas during the testing process.
[0013] 2. The pipeline air tightness detector can detect the air tightness of the pipeline to ensure the quality of the pipeline is intact. However, when the pipeline air tightness detector is moved, the connecting plate and the inflation tube are usually placed directly on the detector host for moving. This method can easily cause the connecting plate to fall off, and it is not easy to neatly store and place the connecting plate and the inflation tube. When the storage box moves, the docking block can be driven to move. When the bottom of the docking block moves to the top surface of the detector host, the threaded knob can be tightened so that the end of the threaded knob can be threaded and slid into the inside of the mounting block, thereby fixing the docking block and the mounting block together. When the hook moves, the elastic band can be stretched. When the end of the hook passes through the top of the storage box and is engaged with the inside of the limit block, the elastic band can limit and fix the connecting plate and the inflation tube inside the storage box. At this time, the elastic band is not easy to loosen. Through the storage box, the connecting plate and the inflation tube are not easy to fall off during the movement of the pipeline air tightness detector, and the connecting plate and the inflation tube can be neatly stored and placed.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1、 Figure 2 and Figure 3 It can be seen that the utility model provides a technical solution: a gas leakage-proof pipeline air tightness detector, comprising: a detector host 1, a display screen 2, a control button 3, a connecting plate 4 and a pipe joint 5. The front of the detector host 1 is respectively equipped with a display screen 2 and a control button 3, the back of the detector host 1 is connected to the connecting plate 4 through an inflation tube, the front of the connecting plate 4 is equipped with a pipe joint 5, a fixed block 6 is installed at the front of the connecting plate 4 near the pipe joint 5, the outer side of the fixed block 6 is connected to a connecting ring 7, the front of the connecting ring 7 is connected to a connecting block 8, the inside of the fixed block 6 is connected to a first spring 9, one end of the first spring 9 is connected to a slide plate 10, the end of the slide plate 10 is connected to a two-way arc block 11, the outer side of the fixed block 6 is slidably connected to a sliding sleeve 12, the outer side of the sliding sleeve 12 is connected to a slider 13, a second spring 14 is connected between the sliding sleeve 12 and the connecting ring 7, a sliding structure is formed between the slider 13 and the connecting block 8, the shape of the connecting block 8 is L-shaped, and a sliding structure is formed between the two-way arc block 11 and the fixed block 6.
[0021] In specific implementation, the pipeline air tightness detector is an instrument for testing the air tightness of pipelines or other similar structures. Since the test pipeline is directly plugged into the outside of the pipeline joint 5, the sealing performance of this plugging method is not stable enough and gas leakage is likely to occur. The sliding sleeve 12 can be pushed toward the direction of the connecting plate 4. When the sliding sleeve 12 moves, it can drive the slider 13 to move. When the slider 13 moves, it can slide through the connecting block 8. When the sliding sleeve 12 moves, the second spring 14 can be compressed. When the second spring 14 is compressed to the maximum extent, the end of the test pipeline can be plugged into the outside of the pipeline joint 5. side, so that the test pipe is located between the fixed block 6 and the pipe joint 5. At this time, the sliding sleeve 12 can be loosened. When the sliding sleeve 12 is loosened, it can be reset by the second spring 14. When the sliding sleeve 12 is reset, its inner wall can squeeze the curved surface at one end of the two-way arc block 11. When the two-way arc block 11 is squeezed, it can drive the slide plate 10 to move. When the slide plate 10 moves, it can stretch the first spring 9. The elasticity of the second spring 14 is much greater than the elasticity of the first spring 9. When the curved surface at the other end of the two-way arc block 11 moves to the outer surface of the test pipe, the two-way arc block 11 can squeeze and fix the test pipe.
[0022] See Figure 1 、 Figure 2 and Figure 3 It can be seen that by squeezing and fixing the test pipe, the sealing between the test pipe and the pipe joint 5 is improved, so that gas leakage is less likely to occur in the test pipe during the detection process.
[0023] See Figure 1 and Figure 4It can be seen that a mounting block 15 is installed on the top of the detector host 1, a storage box 16 is provided on the top of the mounting block 15, a docking block 17 is connected to the bottom of the storage box 16, the internal thread of the docking block 17 is connected to a threaded knob 18, an elastic band 19 is connected to the outside of the storage box 16, and a hook 20 is connected to the end of the elastic band 19. A limiting block 21 is installed on the outside of the storage box 16, and the hook 20 is made of plastic.
[0024] During specific implementation, the pipeline air tightness detector can detect the air tightness of the pipeline, so as to ensure the quality of the pipeline is intact. In the process of moving the pipeline air tightness detector, the connecting plate 4 and the inflation tube are usually placed directly on the detector host 1 for moving. This method is easy to cause the connecting plate 4 to fall off, and it is also not easy to neatly store the connecting plate 4 and the inflation tube. You can first push the storage box 16. When the storage box 16 moves, it can drive the docking block 17 to move. When the bottom of the docking block 17 moves to the top surface of the detector host 1, the thread can be rotated. The button 18 is tightened so that the end of the threaded knob 18 can be threadedly slid into the inside of the mounting block 15, thereby fixing the docking block 17 and the mounting block 15 together. At this time, the connecting plate 4 and the inflation tube can be neatly placed in the storage box 16, and the hook 20 is pulled toward the direction of the limit block 21. When the hook 20 moves, the elastic band 19 can be stretched. When the end of the hook 20 passes through the top of the storage box 16 and is engaged with the inside of the limit block 21, the elastic band 19 can limit and fix the connecting plate 4 and the inflation tube inside the storage box 16. At this time, the elastic band 19 is not easy to loosen.
[0025] See Figure 1 and Figure 4 It can be seen that the storage box 16 can prevent the connecting plate 4 and the inflation tube from falling off during the movement of the pipeline air tightness detector, and can also neatly store and place the connecting plate 4 and the inflation tube.
[0026] To sum up, when using the gas leak-proof pipeline air tightness detector, the sliding sleeve 12 can be pushed toward the connecting plate 4 first. When the sliding sleeve 12 moves, the slider 13 can be driven to move. When the slider 13 moves, it can slide through the connecting block 8. When the arc surface at the other end of the two-way arc block 11 moves to the outer surface of the test pipe, the two-way arc block 11 can squeeze and fix the test pipe. By squeezing and fixing the test pipe, the sealing between the test pipe and the pipe joint 5 is improved, so that the test pipe is not prone to gas leakage during the detection process. The storage box 16 can prevent the connecting plate 4 and the inflation tube from falling off during the movement of the pipeline air tightness detector, and the connecting plate 4 and the inflation tube can be neatly stored and placed.
