[0001] This utility model belongs to the field of sealing performance testing, and specifically relates to a convenient sealing performance testing device. Background Technology

[0002] In industrial production, many products (such as valves, seals, pipe fittings, and containers) require good sealing performance to prevent gas or liquid leakage. Therefore, sealing tests are usually conducted before products leave the factory to ensure that their quality meets standards.

[0003] Currently, commonly used methods for leak detection include pneumatic pressure testing, hydrostatic testing, bubble detection, and helium mass spectrometry leak detection. However, existing leak detection equipment still has many shortcomings, specifically in the following aspects:

[0004] 1. Complex structure and inconvenient operation: Most traditional testing equipment is large in size and complex in structure. The installation and debugging process is cumbersome and it is difficult to adapt to the needs of rapid on-site testing or mobile testing, which limits its application in small enterprises or on-site operations.

[0005] 2. Cumbersome and inefficient testing process: Traditional equipment mostly relies on manual operation, making the entire testing process cumbersome, the labor intensity of operators high, and the overall testing efficiency low, making it difficult to meet the testing efficiency requirements of modern production.

[0006] 3. Lack of discharge function and excessive manual intervention: Traditional equipment often only considers clamping and sealing effects, which makes these two parts occupy a lot of space. After the test is completed, it is not easy for workers to smoothly remove the tested products. Utility Model Content

[0007] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a convenient sealing test device that is simple in structure, easy to operate, and improves testing efficiency and ease of use.

[0008] The objective of this utility model can be achieved by addressing the following technical problem: providing a convenient sealing performance testing device, comprising a frame, a lifting mechanism, and a turning mechanism, wherein:

[0009] The frame is equipped with a testing box;

[0010] The lifting mechanism is mounted on the frame and includes a placement rack and a rotating tube. The placement rack is connected to the moving end of the lifting mechanism and is movably mounted inside the testing chamber. The rotating tube is movably connected to the placement rack and has several positioning parts arranged in an array on it. One end of the product to be tested is connected to the positioning part, and the other end is connected to the placement rack. The testing gas introduced into the rotating tube can enter the product through the positioning parts to test the product's sealing performance.

[0011] The material turning mechanism is used to drive the rotating tube to rotate relative to the material placement frame, so that the end of the product away from the positioning part extends out of the detection box;

[0012] After the product inspection is completed, the lifting mechanism is used to lift the material rack to the opening end of the inspection box, and the product is tilted by the flipping mechanism so that the user can take out the product.

[0013] In the aforementioned portable sealing testing device, the lifting mechanism further includes a lifting cylinder and a fixing rod. The lifting cylinder is mounted on the frame, and the output end of the lifting cylinder is connected to a moving block. The top end of the fixing rod is connected to the moving block, and the bottom end is connected to the material placement rack.

[0014] In the aforementioned portable sealing testing device, the material turning mechanism includes a mounting base and an adsorption component. An extension block is formed on the material rack, and the mounting base is disposed on the extension block and located above the rotating tube. The adsorption component is disposed on the mounting base and is used to adsorb the rotating tube and drive it to rotate relative to the material rack.

[0015] In the aforementioned portable sealing testing device, the flipping mechanism further includes a fixed shaft and a rotating block. The fixed shaft is connected to the moving block, and the opening end of the testing box is provided with a cover plate. The rotating block is connected to the cover plate and is movably mounted on the fixed shaft.

[0016] In the aforementioned portable sealing test device, the material rack is provided with a number of positioning slots, each of which corresponds to a positioning part. The end of the product furthest from the positioning part is movably engaged into the positioning slot.

[0017] In the aforementioned convenient sealing test device, the rotating tube has a connecting block formed along its radial direction, and a locking nut is installed on the connecting block. The locking nut can restrict the gas pipeline to the connecting block when it is connected.

[0018] In the aforementioned portable sealing test device, a digital display is also connected to the gas pipeline, which is used to display the parameter values ​​of the introduced test gas.

[0019] In the aforementioned portable sealing testing device, a start / stop switch is also provided on the frame, which is used to control the start and stop of the testing operation.

[0020] In the aforementioned convenient sealing test device, the material rack has an installation hole, and a bearing is installed at the end of the rotating tube. The inner ring of the bearing is interference-fitted with the inner wall of the installation hole.

[0021] In the aforementioned portable sealing testing device, a limiting block is also provided on the frame, the limiting block extending to one side of the testing box to restrict the testing box from detaching from the frame.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) This utility model provides a convenient sealing test device. By setting a rotating tube with a positioning part, the product to be tested can be quickly and stably fixed on the material rack for testing. At the same time, the test gas can be evenly introduced into the product through the rotating tube and the positioning part to ensure the stability of the test process and the accuracy of the data. The rotating tube is driven to rotate by the material turning mechanism, so that the product after the test is completed can be automatically tilted and extended out of the test box, which makes it easy for users to quickly and safely take out the product. This improves the testing efficiency and operation convenience. The overall structure is compact and easy to operate, and it is suitable for various product sealing test scenarios.

[0024] (2) By adsorbing the rotating tube with the adsorption element and driving it to rotate, the product flipping action is precisely controlled. The structure is simple and responds quickly. It can achieve the flipping function without a complex transmission mechanism, which reduces the equipment maintenance cost and improves the stability and repeatability of the flipping action.

[0025] (3) By using an interference fit, a stable connection between the rotating tube and the material rack is achieved, which ensures the stability and accuracy of the rotating tube during rotation, reduces mechanical wear, extends the service life of the equipment, and improves the smoothness and reliability of the material turning action.

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0034] like Figures 1 to 3 As shown, this utility model provides a convenient sealing performance testing device, which includes a frame 1, a lifting mechanism 2, and a turning mechanism 3.

[0035] The machine frame 1 is equipped with a testing box 10. A lifting mechanism 2 is mounted on the machine frame 1. The lifting mechanism 2 includes a placement rack 20 and a rotating tube 21. The placement rack 20 is connected to the moving end of the lifting mechanism 2 and is movably disposed inside the testing box 10. The rotating tube 21 is movably connected to the placement rack 20, and several positioning parts 210 are arrayed on the rotating tube 21. One end of the product to be tested is connected to the positioning part 210, and the other end is connected to the placement rack. The testing gas introduced into the rotating tube 21 can enter the product through the positioning part 210 to test the product's sealing performance. A flipping mechanism 3 is used to drive the rotating tube 21 to rotate relative to the placement rack 20, so that the end of the product away from the positioning part 210 extends out of the testing box 10. After the product testing is completed, the lifting mechanism 2 is used to lift the placement rack 20 to the open end of the testing box 10, and the flipping mechanism 3 drives the product to tilt so that the user can take out the product.

[0036] Before the testing operation begins, the lifting mechanism 2 can raise the placement rack 20 to the open end of the testing box 10. At this time, the operator can fix one end of the product to be tested (such as a sealed container, pipe fitting, etc.) to the positioning part 210 on the rotating tube 21, and the other end to the placement rack 20, ensuring that the product will not shake or shift during the testing process. Since the rotating tube 21 is provided with multiple positioning parts 210 arranged in an array, multiple products to be tested can be installed at the same time (in this embodiment, there are eight sets of positioning parts 210, which are suitable for batch testing and have high testing efficiency). As the lifting mechanism resets the placement rack 20 to the testing position (i.e., the bottom of the testing box 10), the testing gas (such as compressed air or inert gas) is introduced into the rotating tube 21 through an external air source. The gas enters the product through the positioning part 210, forming a sealed testing environment. If there is a leak, the leaked gas will be captured by the sensor in the testing box 10, thereby determining whether the product is qualified. This testing process does not require manual intervention, which improves the testing efficiency and the consistency and accuracy of the testing results. After the test is completed, the lifting mechanism can once again lift the material rack 20 along with the product to the opening end of the test box 10. At this time, under the action of the flipping mechanism 3, the rotating tube 21 can be driven to rotate relative to the material rack 20 at a certain angle until the product is in an inclined state, making it easy for the operator to identify and remove it. Therefore, this embodiment realizes the automatic lifting, flipping and unloading operation of the product through the lifting mechanism 2 and the flipping mechanism 3, which significantly improves the testing efficiency and ease of operation. At the same time, the testing gas can enter the product through the rotating tube 21 and the positioning part 210 to achieve efficient sealing test. In addition, the flipping mechanism 3 allows the product to tilt and extend out of the test box 10 after the test is completed, making it easy for the operator to quickly remove the material, improving work efficiency, reducing manual intervention, and demonstrating good practicality and automation level.

[0037] The lifting mechanism 2 also includes a lifting cylinder 22 and a fixing rod 23. The lifting cylinder 22 is mounted on the frame 1. The output end of the lifting cylinder 22 is connected to a moving block 220. The top end of the fixing rod 23 is connected to the moving block 220, and the bottom end is connected to the material placement rack 20.

[0038] like Figure 1 and Figure 2 As shown, after the product to be tested is fixed by the positioning part 210 on the rotating tube 21 in conjunction with the material rack 20, the lifting cylinder 22 can then drive the material rack 20 from its original initial position (i.e., the top opening of the testing box 10) along... Figure 2The device descends vertically to the detection position (i.e., the bottom inside the detection chamber 10). During this process, the output end of the lifting cylinder 22 pushes the moving block 220 to move, thereby causing the fixed rod 23 and the material rack 20 to rise or fall together. This ensures that the material rack 20, along with the product inside, can reach the required position in a horizontal posture, ensuring the smoothness and stability of the entire sealing detection process. Therefore, this structure achieves stable lifting and lowering control of the material rack 20, ensuring that the product can accurately enter the detection chamber 10 during the detection process, and lifting the product to the opening of the detection chamber 10 after the detection is completed, facilitating subsequent flipping and material removal operations. The overall structure is simple and reliable, with high control precision, improving the stability and automation of equipment operation.

[0039] The material turning mechanism 3 includes a mounting base 30 and an adsorption component. An extension block 200 is formed on the material rack 20. The mounting base 30 is located on the extension block 200 and above the rotating tube 21. The adsorption component is located on the mounting base 30 and is used to adsorb the rotating tube 21 and drive it to rotate relative to the material rack 20.

[0040] like Figure 2 As shown, after the product sealing test is completed, the lifting cylinder 22, along with the moving block 220 and the fixing rod 23, lifts the material rack 20 and the product to the top opening of the testing box 10. Since the product is still connected to the positioning part 210 and the material rack 20, the control system can control the adsorption element to adsorb the rotating tube 21. As the rotating tube 21 rotates relative to the material rack 20 along its axial direction (i.e., the rotating tube 21 rotates towards the adsorption element), the end of the product away from the positioning part 210 is disengaged from the material rack 20 until the product is in an inclined position. Preferably, the adsorption element in this embodiment can preferably adopt a strong magnetic structure (such as a magnet). This structure effectively avoids collisions or damage to the product caused by traditional mechanical transmission, improves the safety of the product testing process, and at the same time, the structure has a fast response speed and flexible control, which helps the product unloading operation, reduces the difficulty of manual operation, and improves the automation level and work efficiency of the testing process.

[0041] The flipping mechanism also includes a fixed shaft 31 and a rotating block 32. The fixed shaft 31 is connected to the moving block 220. The opening end of the detection box 10 is provided with a cover plate. The rotating block 32 is connected to the cover plate and is movably mounted on the fixed shaft 31.

[0042] In this embodiment, the cover plate can rotate relative to the testing box 10, so that workers can easily remove the product from the placement rack 20. It should be noted that when the product to be tested is connected to the positioning part 210, the testing gas in the rotating tube 21 can be introduced into the product (that is, the qualified product should only have the end connected to the positioning part 210 connected to the outside). Therefore, by setting the fixed shaft 31 and the rotating block 32 structure, the cover plate (not shown in the figure) and the rotating block 32 form a linkage relationship, ensuring that when the lifting cylinder 22 lifts the placement rack 20 together with the product to the top opening position of the testing box 10, the product can be removed by flipping the cover plate. This structure effectively ensures the smoothness and safety of the testing process, avoids the entry of external dust or impurities that may affect the accuracy of the entire testing result, and enhances the overall coordination and automation control capability of the equipment.

[0043] The material rack 20 has several positioning slots 201, which are set one-to-one with the positioning part 210. The end of the product away from the positioning part 210 is movably engaged into the positioning slot 201.

[0044] like Figure 2 As shown, in this embodiment, the material rack 20 is provided with positioning grooves 201 (8 sets) that correspond one-to-one with the positioning part 210, so that the end of the product away from the positioning part 210 can be firmly locked in the positioning groove 201, ensuring that the product maintains a stable posture during the testing process, avoiding the product from falling off or shifting due to vibration or gas pressure, improving the accuracy and reliability of the test, and also facilitating the quick clamping and disassembly of the product.

[0045] The rotating tube 21 has a connecting block 211 formed in its radial direction. A locking nut 211a is installed on the connecting block 211. The locking nut 211a can restrict the gas pipe 211b to the connecting block 211 when it is connected.

[0046] like Figure 2 and Figure 3 As shown, in this embodiment, a connecting block 211 and a locking nut 211a are provided on the rotating tube 21. During installation, as the gas pipe 211b is connected to the positioning part 210, the gas pipe 211b can be firmly fixed to the connecting block 211 by tightening the locking nut 211a. This prevents the gas pipe 211b from falling off due to gas pressure fluctuations or vibrations, ensuring the stability and safety of gas supply during the detection process, and improving the reliability and service life of the equipment.

[0047] Preferably, such as Figure 1As shown, this embodiment also includes a digital display 11 on the gas pipeline 211b. The digital display 11 can display the pressure, flow rate and other parameters of the gas being tested in real time, which is convenient for operators to monitor the testing process, detect abnormalities in a timely manner and make adjustments, improve the testing accuracy and the intelligence level of the equipment, and help to realize the visual management of testing data.

[0048] Preferably, such as Figure 1 As shown, a start / stop switch 12 is also provided on the frame 1. The start / stop switch 12 allows the operator to easily control the start and stop of the entire testing process, improves the flexibility and safety of equipment operation, avoids equipment damage or testing failure caused by misoperation, and enhances the operability of the equipment and the human-machine interaction experience.

[0049] The material rack 20 has an installation hole 202 inside, and a bearing is installed at the end of the rotating tube 21. The inner ring of the bearing is interference-fitted with the inner wall of the installation hole 202.

[0050] like Figure 2 As shown, by providing a bearing (not shown in the figure) at the end of the rotating tube 21 and installing it with an interference fit with the mounting hole 202 on the material rack 20, the rotating tube 21 is ensured to run smoothly and with low frictional resistance during rotation, thus extending the service life of the equipment. At the same time, the rotation accuracy and stability are improved, ensuring the accuracy of the product posture during the testing process.

[0051] like Figure 1 As shown, in this embodiment, a limiting block 13 is also provided on the frame 1. The limiting block 13 extends to one side of the test box 10, which effectively prevents the test box 10 from shifting or falling off the frame 1 during operation, ensuring the installation stability of the test box 10, improving the safety and reliability of the overall equipment structure, avoiding test failure or equipment damage due to box offset, and ensuring the normal operation of the test.
