Description

Technical Field

[0001] This invention relates to the field of airtightness testing technology, specifically to a fault diagnosis device that facilitates the installation and replacement of testing probes. Background Technology

[0002] Fault diagnosis equipment plays a crucial role in many fields such as modern industrial production, transportation, and medical care. It is used to detect, locate, and analyze faults in various equipment or systems to ensure their safe and stable operation. It collects physical quantities such as temperature, pressure, vibration, current, and voltage in real time through various sensors. In sealing devices, the most common fault diagnosis equipment is airtightness testing equipment. Airtightness testing equipment is used to detect whether there is a leak in an object or system to ensure its airtightness. It usually uses differential pressure method or direct pressure method for detection. The direct pressure method involves directly filling the workpiece with a certain pressure of gas. After a stabilization time, the pressure change inside the workpiece is measured to determine whether there is a leak.

[0003] In existing airtightness testing equipment, snap-fit ​​connections are usually used to accommodate different sizes of container openings. However, the snap-fit ​​positions are usually sealed only with rubber gaskets, which can lead to air leakage after the air pressure increases. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A fault diagnosis device that facilitates the installation and replacement of detection probes includes:

[0006] A frame, on the top of which a cylinder and an air pump are fixedly installed, the output end of which passes through the frame and extends into its interior;

[0007] A fixing mechanism is installed at the center of the frame, and a display is installed inside the frame.

[0008] A connecting plate is fixedly installed at the output end of the cylinder, and a clamping sleeve is fixedly installed at the bottom of the connecting plate;

[0009] A sealing mechanism is installed at the bottom of the cartridge and is used to connect to the container interface to be tested. A pressure sensor is installed on the inner wall of the sealing mechanism and is electrically connected to the display.

[0010] The sealing mechanism also includes a cover, with a buckle cylinder fixedly installed on the top of the cover, buckle blocks evenly arranged on the top of the inner wall of the buckle cylinder, and an inner groove plate fixedly installed on the bottom of the inner wall of the buckle cylinder, with an annular groove provided on the top of the inner groove plate.

[0011] The bottom outer side of the clamping cylinder is evenly provided with clamping blocks. The clamping cylinder engages with the buckle blocks of the buckle cylinder via these clamping blocks. A rubber ring is fixedly installed at the bottom of the clamping cylinder, and the rubber ring corresponds to the annular groove of the inner groove plate. Through the cooperation between the clamping cylinder and the buckle cylinder, during the connection process, the clamping blocks of the clamping cylinder engage with the buckle blocks of the buckle cylinder. When detecting containers of different sizes, the pressure sensor can be replaced simultaneously with the sealing mechanism, accelerating the replacement speed of the detection probe. At the same time, the clamping allows the pressure sensor to be quickly installed along with the sealing mechanism. During the clamping process, the rubber ring engages with the annular groove of the inner groove plate. During the clamping process, the rubber ring and the inner groove plate are tightly fitted together. During the testing process, the pressure applied by the cylinder is further increased to increase the fitting pressure between the rubber ring and the inner groove plate. At the same time, the ring groove restricts the deformation range of the rubber ring, improving the sealing of the clamping position and avoiding air leakage during the airtightness test, which would lead to incorrect test results. A rubber cylinder is clamped to the top of the inner wall of the clamping cylinder, and a groove is opened at the bottom of the rubber cylinder. A slip ring is clamped to the bottom of the rubber cylinder through the groove. A connector is fixedly installed on the inner wall of the slip ring, and the top of the connector is connected to the air pump through a pipe.

[0012] Preferably, the inner wall of the rubber cylinder is tightly fitted to the outer side of the connector, and the outer side of the rubber cylinder is tightly fitted to the inner wall of the clamping sleeve. The outer side of the slip ring slides and adapts to the inner wall of the clamping sleeve, and the bottom of the slip ring has an inner groove. This inner groove increases the contact area with the gas. When the internal gas pressure increases, causing the connector to tend to push out, the connector applies pressure to the rubber cylinder through the slip ring, causing the rubber cylinder to deform between the connector and the clamping sleeve, thus increasing the contact pressure. To prevent the joint from protruding, ensure the gas path connection during pressurization, guarantee the airtightness of the equipment during testing, and avoid air leakage, the cover is a conical cover with an inner diameter and outer diameter gradually decreasing from top to bottom. A sliding groove is provided on the outer side of the cover, and a sliding cover is slidably installed at the sliding groove of the cover. A gasket is snapped between the bottom end of the cover and the sliding cover. A bottom sliding cylinder is fixedly installed at the bottom end of the sliding cover. The bottom end of the bottom sliding cylinder is inclined inward, and an arc-shaped pad is fixedly installed at the bottom end of the bottom sliding cylinder.

[0013] Preferably, both the arc-shaped pad and the gasket ring are made of rubber. The top of the outer side of the cover is fixedly connected to the air pressure sensor. Through the cooperation of the arc-shaped pad and the gasket ring, utilizing the deformation characteristics of rubber, the position of the container is adjusted in conjunction with the fixing mechanism during the pressurization process driven by the cylinder. At the same time, the arc-shaped pad, after contacting the container, utilizes the deformation characteristics of rubber to improve the fit between the pad and the container, forming a seal on the outside of the container opening, achieving double-layer sealing treatment and ensuring the accuracy of airtightness detection. The detection end of the air pressure sensor penetrates through the cover and extends into the interior. The bottom of the inner wall of the cover is provided with an annular protrusion, and a hollow cylinder is slidably installed on the inner wall of the annular protrusion. An outer gasket ring is fixedly installed on the top of the outer side of the hollow cylinder, and a conical cover is fixedly installed on the bottom of the hollow cylinder. The inner diameter of the conical cover gradually increases from top to bottom. The outer gasket ring is made of rubber, and the outer side of the outer gasket ring is tightly fitted to the inner wall of the cover.

[0014] Preferably, the fixing mechanism includes a fixing ring, the bottom of which is fixedly connected to the frame, and a tray is slidably mounted on the top of the inner wall of the fixing ring. A connecting ring is fixedly mounted at the center of the top of the tray, and a support rod is fixedly mounted on the top of the connecting ring. The end of the support rod away from the connecting ring is inclined inward, and the support rod is evenly installed along the center of the connecting ring. A ball is fixedly mounted on the top of the support rod. The shape of the ball reduces the contact area with the container when it contacts the bottom of the container, thereby reducing friction. This, combined with the downward movement of the pressure ring after being stressed, reduces the resistance during container position adjustment, ensuring smooth position adjustment of the container. A pressure ring is fixedly mounted on the bottom of the tray, and a bottom pad ring is fixedly mounted on the bottom of the pressure ring.

[0015] Preferably, the top of the fixing ring is uniformly provided with rotating grooves, and rotating blocks are rotatably installed at the rotating grooves of the fixing ring. A fixing plate is fixedly installed at the top of the rotating block, and a slot plate is fixedly installed at the end of the fixing plate away from the rotating block. An inner pad block is fixedly installed on the outer side of the slot plate. An inner protrusion is fixedly installed on the bottom of the opposite side of the rotating block. The end of the inner protrusion away from the rotating block contacts the bottom of the pressure ring. The bottom pad ring is made of elastic material. Through the bottom pad ring and the inner protrusion, during the compression process, the bottom pad ring changes shape, causing the pressure ring to press down. The inner protrusion drives the rotating block to rotate, so that the inner pad block contacts the outer side of the container. This adjusts the position of the container that is offset from the docking center, so that the container opening position corresponds to the docking position of the equipment. This avoids the inability to dock due to joint misalignment, which would prevent the airtightness test from being performed. The end of the fixing plate away from the rotating block is inclined inward. The side of the slot plate away from the fixing plate is an inclined surface that slopes inward from top to bottom. The outer side of the inner pad block is an arc surface with a central protrusion.

[0016] This invention provides a fault diagnosis device that facilitates the installation and replacement of detection probes. It offers the following advantages:

[0017] I. This fault diagnosis device, which facilitates the installation and replacement of detection probes, utilizes a clamping sleeve and a snap-fit ​​sleeve. During connection, the clamping blocks of the clamping sleeve and the snap-fit ​​sleeve engage, allowing the pressure sensor to be replaced simultaneously with the sealing mechanism when testing containers of different sizes, thus accelerating probe replacement. Simultaneously, the pressure sensor is quickly installed along with the sealing mechanism during engagement. During engagement, the rubber ring engages with the annular groove of the inner groove plate, ensuring a tight fit between the rubber ring and the inner groove plate. During testing, pressure is applied by a cylinder to further increase the contact pressure between the rubber ring and the inner groove plate. The annular groove also limits the deformation range of the rubber ring, improving the sealing performance at the engagement point and preventing air leakage during airtightness testing, which could lead to incorrect test results.

[0018] Second, this fault diagnosis device, which facilitates the installation and replacement of the detection probe, increases the contact area with the gas through the inner groove of the slip ring. When the internal gas pressure increases and the connector tends to be pushed out, the connector applies pressure to the rubber cylinder through the slip ring, causing the rubber cylinder to deform between the connector and the clamp. This increases the fitting pressure while restricting the connector from being pushed out, ensuring the gas path connection during the pressurization process, ensuring the airtightness of the equipment during testing, and preventing air leakage.

[0019] Third, this fault diagnosis device, which facilitates the installation and replacement of detection probes, utilizes the rubber deformation characteristics of the arc-shaped pad and the gasket ring to adjust the position of the container during the pressurization process driven by the cylinder, in conjunction with the fixing mechanism. At the same time, the arc-shaped pad, after contacting the container, utilizes the rubber deformation characteristics to improve the fit between the pad and the container, forming a seal on the outside of the container opening, achieving double-layer sealing treatment and ensuring the accuracy of airtightness testing.

[0020] Fourth, this fault diagnosis device, which facilitates the installation and replacement of detection probes, reduces the contact area with the container and lowers friction when it contacts the bottom of the container through the shape of the ball. This, combined with the downward movement of the pressure ring after being stressed, reduces the resistance during container position adjustment and ensures smooth position adjustment of the container.

[0021] 5. This fault diagnosis device, which facilitates the installation and replacement of the detection probe, uses a bottom pad ring and an inner protrusion. During the compression process, the bottom pad ring changes shape, causing the pressure ring to press down. The inner protrusion then drives the rotating block to rotate, causing the inner pad block to contact the outside of the container. This adjusts the position of the container that is off-center from the docking center, ensuring that the container opening corresponds to the docking position of the device. This avoids the inability to dock due to joint misalignment, which would prevent the airtightness test from being performed. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] First embodiment, such as Figures 1 to 6 As shown, the present invention provides a technical solution:

[0035] A fault diagnosis device that facilitates the installation and replacement of detection probes includes:

[0036] The frame 1 has a cylinder 6 and an air pump 7 fixedly installed on its top. The output end of the cylinder 6 passes through the frame 1 and extends into its interior.

[0037] Fixing mechanism 2 is installed at the center of the frame 1, and a display 5 is installed inside the frame 1.

[0038] The fixing mechanism 2 includes a fixing ring 201. The bottom of the fixing ring 201 is fixedly connected to the frame 1, and a tray 204 is slidably installed on the top of the inner wall of the fixing ring 201. A connecting ring 206 is fixedly installed at the center of the top of the tray 204, and a support rod 207 is fixedly installed on the top of the connecting ring 206. The end of the support rod 207 away from the connecting ring 206 is inclined inward. When a worker inserts a container with the opening facing upward, the bottom of the container is in contact with the ball block 208 on the top of the support rod 207, so that the ball block 208 supports the container. The support rod 207 supports the container under its constraint. During the downward movement of the cylinder 6, after the sealing mechanism 3 contacts the container, the pressure of the cylinder 6 causes the tray 204 to deform by pressing the bottom pad ring 211 through the pressure ring 203, causing the tray 204 and the pressure ring 203 to move downward. The support rod 207 is evenly installed along the center position of the connecting ring 206. A ball block 208 is fixedly installed at the top of the support rod 207, and a pressure ring 203 is fixedly installed at the bottom of the tray 204. A bottom pad ring 211 is fixedly installed at the bottom of the pressure ring 203.

[0039] A connecting plate 4 is fixedly installed at the output end of cylinder 6, and a clamping sleeve 10 is fixedly installed at the bottom of the connecting plate 4.

[0040] A sealing mechanism 3 is installed at the bottom of the cartridge 10 and is used to connect to the container interface position to be detected. A pressure sensor 8 is installed on the inner wall of the sealing mechanism 3, and the pressure sensor 8 is electrically connected to the display 5.

[0041] The sealing mechanism 3 also includes a cover 301, a buckle cylinder 302 is fixedly installed on the top of the cover 301, buckle blocks are evenly arranged on the top of the inner wall of the buckle cylinder 302, and an inner groove plate 304 is fixedly installed on the bottom of the inner wall of the buckle cylinder 302, with an annular groove on the top of the inner groove plate 304.

[0042] Evenly spaced locking blocks are provided on the bottom outer side of the locking cylinder 10. The locking cylinder 10 engages with the locking blocks of the buckle cylinder 302 via these locking blocks. A rubber ring 13 is fixedly installed at the bottom of the locking cylinder 10, and the rubber ring 13 corresponds to the annular groove of the inner groove plate 304. A rubber cylinder 11 is engaged at the top of the inner wall of the locking cylinder 10, and a locking groove is provided at the bottom end of the rubber cylinder 11. When the locking cylinder 10 engages with the sealing mechanism 3, the locking blocks on the outer side of the locking cylinder 10 cooperate with the locking blocks on the inner wall of the buckle cylinder 302 to complete the engagement between the locking cylinder 10 and the buckle cylinder 302. At the same time, during the engagement process, the inner wall of the buckle cylinder 302... The inner groove 304 of the wall cooperates with the rubber ring 13 fixedly installed at the bottom of the clamping cylinder 10. During the clamping process, the rubber ring 13 is inserted into the annular groove of the inner groove 304. At the same time, the contact between the annular groove and the rubber ring 13 increases the curvature of the contact position. During the connection of the container opening, the pressure applied by the cylinder 6 increases the contact pressure between the rubber ring 13 and the inner groove 304, improving the air seal. The bottom end of the rubber cylinder 11 is clamped with a slip ring 12 through a groove. The inner wall of the slip ring 12 is fixedly installed with a connector 9. The top end of the connector 9 is connected to the air pump 7 through a pipe.

[0043] The inner wall of the rubber cylinder 11 fits tightly against the outer side of the connector 9, and the outer side of the rubber cylinder 11 fits tightly against the inner wall of the clamping cylinder 10. The outer side of the slip ring 12 slides and adapts to the inner wall of the clamping cylinder 10, and the bottom of the slip ring 12 has an inner groove. When the air pump 7 starts, air enters the connector 9 through the pipe, and then, through the cooperation of the clamping cylinder 10 and the sealing mechanism 3, the air is introduced into the container. As the internal air pressure gradually increases, the air pressure through the connector 9 causes the connector 9 to tend to push out. At this time, the slip ring 12 presses the rubber cylinder 11 under this tendency, causing the rubber cylinder 11 to... The deformation trend increases the contact pressure with the connector 9 and the clamping sleeve 10, restricting the connector 9 from being ejected, and at the same time increasing the fitting pressure. The cover 301 is a conical cover with an inner diameter and outer diameter that gradually decrease from top to bottom, and a sliding groove is provided on the outer side of the cover 301. A sliding cover 303 is slidably installed in the sliding groove of the cover 301. A washer ring 305 is clamped between the bottom end of the cover 301 and the sliding cover 303. A bottom sliding cylinder 306 is fixedly installed at the bottom end of the sliding cover 303. The bottom end of the bottom sliding cylinder 306 is inclined inward, and an arc-shaped pad 307 is fixedly installed at the bottom end of the bottom sliding cylinder 306.

[0044] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 7 to 8As shown, both the arc-shaped pad 307 and the gasket 305 are made of rubber. When the sealing mechanism 3 is moved downward by the cylinder 6, it first contacts the container through the arc-shaped pad 307. During the contact process, the contact pressure causes the bottom sliding cylinder 306 to drive the sliding cover 303 to compress the gasket 305, causing the gasket 305 to deform. The sliding cover 303 slides in the groove of the cover cylinder 301. During the sliding process, it works with the fixing mechanism 2 to adjust the position of the container. The top of the outer side of the cover cylinder 301 is fixedly connected to the air pressure sensor 8. The detection end of the air pressure sensor 8 passes through the cover cylinder 301 and extends into the interior. The bottom of the inner wall of the cover cylinder 301 is provided with an annular protrusion, and the inner wall of the annular protrusion... A hollow cylinder 309 is slidably installed. An outer gasket 308 is fixedly installed on the top of the outer side of the hollow cylinder 309, and a conical cover 310 is fixedly installed on the bottom of the hollow cylinder 309. When the sliding cover 303 slides, the conical cover 310 contacts the opening of the container. Through the change of the inner diameter of the conical cover 310, the opening of the container is wrapped during the contact process. At the same time, under the contact pressure, the hollow cylinder 309 drives the outer gasket 308, which increases the contact pressure between the outer gasket 308 and the cover cylinder 301. The inner diameter of the conical cover 310 gradually increases from top to bottom. The outer gasket 308 is made of rubber material, and the outer side of the outer gasket 308 is tightly fitted to the inner wall of the cover cylinder 301.

[0045] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 9 to 10 As shown, the top of the fixing ring 201 is evenly provided with rotating grooves, and rotating blocks 202 are rotatably installed at each rotating groove of the fixing ring 201. A fixing plate 205 is fixedly installed at the top of the rotating block 202, and a slot plate 209 is fixedly installed at the end of the fixing plate 205 away from the rotating block 202. An inner pad 210 is fixedly installed on the outer side of the slot plate 209. An inner protrusion 212 is fixedly installed on the bottom of the opposite side of the rotating block 202. During the downward movement of the pressure ring 203, the inner protrusion 212 moves with the downward movement of the pressure ring 203 through contact with the inner protrusion 212, thereby driving the rotating block 202. The top of 02 moves inward. During the movement, the fixing plate 205 and the slot plate 209 drive the inner pad 210 to contact the container, adjusting the position of the container so that the opening position of the container corresponds to the sealing mechanism 3. The end of the inner protrusion 212 away from the rotating block 202 contacts the bottom of the pressure ring 203. The bottom pad ring 211 is made of elastic material. The end of the fixing plate 205 away from the rotating block 202 is inclined inward. The side of the slot plate 209 away from the fixing plate 205 is an inclined surface that slopes inward from top to bottom. The outer side of the inner pad 210 is an arc surface with a central protrusion.

[0046] In use, the worker places the container to be tested into the equipment and pre-fixes it using the fixing mechanism 2. Then, according to the diameter of the container opening, a suitable sealing mechanism 3 is selected and the sealing mechanism 3 is engaged with the clamping cylinder 10. Then, the cylinder 6 is activated, causing the cylinder 6 to move the sealing mechanism 3 close to the opening of the container through the connecting plate 4 and the clamping cylinder 10, and engage the sealing mechanism 3 with the opening of the container. Then, the air pump 7 is activated, causing the air pump 7 to inject air into the container through the pipeline, and the internal air pressure is detected by the air pressure sensor 8. The air pressure sensor 8 transmits the electrical signal to the display 5 for display, and the airtightness of the container is detected based on the displayed data.

[0047] When the container is placed into the fixing mechanism 2, the worker places the container with the opening facing upwards, so that the bottom of the container is in contact with the ball block 208 at the top of the support rod 207. The ball block 208 supports the container under the constraint of the support rod 207. During the downward movement of the cylinder 6, after the sealing mechanism 3 contacts the container, the pressure of the cylinder 6 causes the tray 204 to deform by pressing the bottom pad ring 211 through the pressure ring 203, causing the tray 204 and the pressure ring 203 to move downwards. During the downward movement of the pressure ring 203, the inner protrusion 212 moves with the downward movement of the pressure ring 203, causing the top of the rotating block 202 to move inwards. During the movement, the inner pad block 210 contacts the container through the fixing plate 205 and the slot plate 209, adjusting the position of the container so that the opening position of the container corresponds to the sealing mechanism 3.

[0048] When the clamping cylinder 10 engages with the sealing mechanism 3, the clamping block on the outside of the clamping cylinder 10 cooperates with the buckling block on the inner wall of the buckling cylinder 302, thus completing the engagement between the clamping cylinder 10 and the buckling cylinder 302. Simultaneously, during the engagement process, the inner groove plate 304 on the inner wall of the buckling cylinder 302 engages with the rubber ring 13 fixedly installed at the bottom of the clamping cylinder 10. During the engagement, the rubber ring 13 engages in the annular groove of the inner groove plate 304. The contact between the annular groove and the rubber ring 13 increases the curvature of the contact area. During the connection of the container opening, the cylinder 6 applies pressure... The pressure increases the contact pressure between the rubber ring 13 and the inner groove plate 304, improving the air seal. At the same time, when the air pump 7 starts, air enters the joint 9 through the pipe, and then, through the cooperation of the clamp 10 and the sealing mechanism 3, the air is introduced into the container. As the internal air pressure gradually increases, the air pressure passes through the joint 9, causing the joint 9 to tend to push out. At this time, the slip ring 12 presses the rubber cylinder 11 under this tendency, causing the rubber cylinder 11 to tend to deform, increasing the contact pressure with the joint 9 and the clamp 10, restricting the joint 9 from pushing out, and at the same time increasing the contact pressure.

[0049] In the sealing mechanism 3, when the sealing mechanism 3 is driven downward by the cylinder 6, it first contacts the container through the arc-shaped pad 307. At the same time, during the contact process, the contact pressure causes the bottom sliding cylinder 306 to drive the sliding cover 303 to compress the pad ring 305, causing the pad ring 305 to deform. The sliding cover 303 slides in the sliding groove of the cover cylinder 301. During the sliding process, it works with the fixing mechanism 2 to adjust the position of the container. At the same time, when the sliding cover 303 slides, the conical cover 310 contacts the opening of the container. Through the change of the inner diameter of the conical cover 310, the opening of the container is wrapped during the contact process. At the same time, under the contact pressure, the hollow cylinder 309 drives the outer pad ring 308, increasing the contact pressure between the outer pad ring 308 and the cover cylinder 301.
