Description

Technical Field

[0001] This application relates to the technical field of pressure resistance testing devices for rubber seals, and particularly to a pressure resistance testing device for rubber seals. Background Technology

[0002] Currently, existing pressure resistance testing equipment is mainly used to evaluate the compressibility of various materials and products, especially in the photovoltaic industry, where testing the pressure resistance of rubber seals is particularly important. These devices typically consist of a compression plate, a limiting block, and fasteners, with the design of the limiting block determining the maximum compressibility achievable by the tested workpiece.

[0003] However, in existing technologies, the height of the limiting blocks is usually fixed. This means that a series of limiting blocks of different specifications need to be prepared to match rubber seals of different thicknesses or heights. This not only increases equipment costs but also makes the test preparation process cumbersome, reducing the flexibility and efficiency of the test. Furthermore, because the limiting blocks cannot be precisely adjusted, it is difficult to compress the workpiece to the required precise ratio, affecting the accuracy of the test results. Utility Model Content

[0004] This application provides a pressure resistance testing device for rubber seals, which at least solves the problem that existing pressure resistance testing devices are difficult to meet the requirements of seals of different heights, resulting in complicated operation and low testing efficiency.

[0006] In some embodiments, the rubber seal pressure resistance testing apparatus further includes:

[0007] At least one guide component is provided in correspondence with at least one pressure plate. A portion of the guide component is connected to the base plate, and the pressure plate is movably connected to another portion of the guide component, so that the adjusting component drives the pressure plate to move closer to or away from the base plate along the extension direction of the guide component.

[0008] In some embodiments, the guiding component includes:

[0009] Multiple guide rods are spaced apart on the base plate. The base plate has multiple mounting holes that correspond one-to-one with the multiple guide rods. One end of each guide rod is detachably connected to a mounting hole. The pressure plate has multiple guide holes that correspond one-to-one with the multiple guide rods. The other end of each guide rod passes through a guide hole and is slidably connected to the pressure plate.

[0010] In some embodiments, the guide assembly further includes: a plurality of elastic elements, which are disposed and sleeved on the guide rods in a one-to-one correspondence with the plurality of guide rods, one end of the elastic element being connected to the base plate and the other end of the elastic element being connected to the pressure plate.

[0011] In some embodiments, each placement area includes a plurality of placement positions spaced apart for placing a plurality of seals to be tested correspondingly on the plurality of placement positions; the extrusion part is an extrusion block protruding from the side surface of the pressure plate facing the base plate, for pressing the seals to be tested located at the plurality of placement positions by the extrusion block.

[0012] In some embodiments, a first connecting hole is provided on the base plate, and a second connecting hole is provided on the pressure plate. The adjusting assembly includes: a first connecting rod, at least a portion of the first connecting rod is provided with an external threaded section, and one end of the first connecting rod is rotatably connected to the first connecting hole; and a first adjusting knob, the other end of the first connecting rod passing through the second connecting hole and connected to the first adjusting knob, and the external threaded section on the first connecting rod being threadedly connected to the second connecting hole.

[0013] In some embodiments, the adjusting assembly includes: a connecting frame, one end of which is connected to the base plate, and the other end of which is located above the pressure plate, and a third connecting hole is provided on the connecting frame; a second connecting rod, at least a portion of which is provided with an external threaded section, the second connecting rod passing through and threadedly connected to the third connecting hole, a second adjusting knob being provided on the end of the second connecting rod away from the pressure plate, and the other end of the second connecting rod being rotatably connected to the pressure plate.

This allows for adjustment of the compression amount for seals of different heights, ensuring uniform and accurate compression force during testing and improving the reliability of test results. It also avoids the limitations of using fixed-height limiting blocks, enhancing the adaptability of the testing device to products of various specifications. This solves the problem of existing pressure resistance testing devices being unable to meet the needs of seals of different heights, leading to complex operation and low testing efficiency. Furthermore, since at least one pressure plate corresponds to at least one placement area, and the pressure plate is movable relative to the base plate, the device can flexibly meet the testing needs of rubber seals of different sizes and thicknesses. It can simultaneously perform pressure resistance tests on multiple seals with different preset compression amounts without frequent parts replacement or device structure adjustments, greatly improving the adaptability and efficiency of the test.

[0019] Meanwhile, another part of the adjustment component is movably connected to the pressure plate, meaning that the operator can change the position of the pressure plate to achieve the required compression by simply operating it, eliminating the complicated adjustment process in traditional devices, such as replacing the fixed height block or manually adjusting the screw, thereby improving the convenience of operation and the overall efficiency of the testing work.

Existing testing equipment usually consists of a compression plate, a limiting block, and fasteners. The design of the limiting block determines the maximum compression that the workpiece under test can achieve. The height of traditional limiting blocks is usually fixed, which makes it difficult to meet the needs of seals of different heights, resulting in complicated operation and low testing efficiency.

[0029] This application provides a pressure resistance testing device for rubber seals.

[0039] The embodiments of this application will now be described in detail with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the embodiments of this application to facilitate a better understanding of the application. However, the technical solutions claimed in this application can be implemented even without these technical details and various variations and modifications based on the following embodiments.

[0040] According to some embodiments of this application, such as Figure 1 As shown, a pressure resistance testing device for rubber seals is provided, comprising: a base plate 10, on which at least one placement area is provided for placing the seal 1 to be tested; a pressure plate 21 assembly 20, including at least one pressure plate 21, each pressure plate 21 being movably disposed relative to or away from the base plate 10, each pressure plate 21 being disposed in a one-to-one correspondence with at least one placement area, and each pressure plate 21 having a compression portion disposed on the side facing the base plate 10; and at least one adjustment assembly 30, disposed in a one-to-one correspondence with at least one pressure plate 21, a part of the adjustment assembly 30 being connected to the base plate 10, and the other part of the adjustment assembly 30 being movably connected to the pressure plate 21, so that the compression portion on the pressure plate 21 is moved by the adjustment assembly 30 to contact the seal 1 to be tested and press the seal 1 to be tested to a preset compression amount.

[0041] In this way, by adjusting the movable connection between the component 30 and the pressure plate 21, the pressure of the extrusion part on the pressure plate 21 in contact with the seal 1 to be tested can be precisely controlled, thereby achieving adjustment of the compression amount for seals of different heights. This ensures that the compression force on the seal is uniform and accurate during the test, improving the reliability of the test results. It also avoids the limitations of using a fixed height limiting block, improving the adaptability of the testing device to products of various specifications. This solves the problem that existing pressure resistance testing devices cannot meet the requirements of seals 1 of different heights, resulting in complex operation and low testing efficiency. Furthermore, since at least one pressure plate 21 is corresponding to at least one placement area, and the pressure plate 21 is movable relative to the base plate 10, the device can flexibly meet the testing needs of rubber seals of different sizes and thicknesses. It can simultaneously perform pressure resistance tests on multiple seals 1 with different preset compression amounts without frequent replacement of parts or adjustment of the device structure, greatly improving the adaptability and efficiency of the test.

[0042] Meanwhile, another part of the adjustment component 30 is movably connected to the pressure plate 21, which means that the operator can change the position of the pressure plate 21 with simple operation to achieve the required compression, eliminating the complicated adjustment process in traditional devices, such as replacing the fixed height block or manually adjusting the screw, thereby improving the convenience of operation and the overall efficiency of the testing work.

[0043] In some embodiments, the rubber seal pressure resistance testing device further includes: at least one guide assembly 40, which is provided in a one-to-one correspondence with at least one pressure plate 21. A portion of the guide assembly 40 is connected to the base plate 10, and the pressure plate 21 is movably connected to another portion of the guide assembly 40, so that the adjusting assembly 30 drives the pressure plate 21 to move closer to or away from the base plate 10 along the extension direction of the guide assembly 40.

[0044] The aforementioned configuration provides a precise trajectory for the movement of the pressure plate 21 via the guide assembly 40. This ensures that the pressure plate 21 moves stably along a predetermined vertical direction as it approaches or moves away from the base plate 10, avoiding test errors caused by unstable lateral or tilting movements. This improves the stability and accuracy of the entire testing process, enhancing the reliability and repeatability of the test results. Furthermore, the design of the guide assembly 40 reduces friction and wear during the movement of the pressure plate 21, extending the equipment's service life. Especially under high-temperature aging test conditions, reduced friction lowers additional heat generation, maintaining a stable test environment temperature and thus affecting the test results.

[0045] In some embodiments, the guide assembly 40 includes: a plurality of guide rods 41 spaced apart on the base plate 10; a plurality of mounting holes 11 corresponding to the plurality of guide rods 41; one end of each guide rod 41 being detachably connected to the mounting hole 11; and a plurality of guide holes 210 corresponding to the plurality of guide rods 41 on the pressure plate 21; the other end of each guide rod 41 passing through the guide hole 210 and being slidably connected to the pressure plate 21.

[0046] The multiple guide rods 41 provide multi-point support, ensuring smooth movement of the pressure plate 21 along the predetermined direction even under high compressive forces. This avoids structural swaying or deformation that might occur with single-point support, significantly enhancing the overall structural stability and reliability of the testing device. The precise fit between the guide rods 41 and the mounting holes 11 on the base plate 10 and the guide holes 210 on the pressure plate 21 effectively restricts the movement path of the pressure plate 21, ensuring accurate vertical movement. This design avoids lateral displacement or tilting, allowing the rubber seal under test to be subjected to uniform and vertical compressive force, thereby improving the accuracy of the test results.

[0047] The guide rod 41 is detachably connected to the base plate 10 and the pressure plate 21, eliminating the need to disassemble the entire testing device when maintaining or replacing the guide rod 41. This greatly simplifies the maintenance process, reduces maintenance costs and downtime, and improves equipment availability and maintenance efficiency. Furthermore, the sliding connection of the guide rod 41 allows the pressure plate 21 to move freely in the vertical direction without lateral constraints. This design enables the testing device to accommodate seals of varying thicknesses; only the position of the pressure plate 21 needs to be adjusted, eliminating the need to replace the guide assembly 40, thus enhancing the device's flexibility and applicability.

[0048] In some embodiments, the guide assembly 40 further includes: a plurality of elastic members, which are disposed and sleeved on the guide rods 41 in a one-to-one correspondence with the plurality of guide rods 41, one end of the elastic member being connected to the base plate 10 and the other end of the elastic member being connected to the pressure plate 21.

[0049] In this way, the elastic element design allows it to absorb some of the impact energy during the downward pressure of the pressure plate 21, providing a shock-absorbing and buffering effect. This not only protects the seals from excessive impact and prevents damage to the test sample, but also reduces mechanical impact on the testing device itself, extending its service life. Furthermore, the use of the elastic element helps eliminate minor gaps or vibrations caused by rigid contact in the mechanical structure, ensuring the smoothness and stability of the pressure plate 21 during movement, thereby improving pressure control accuracy during testing and obtaining more reliable test data. Simultaneously, the buffering effect of the elastic element reduces the pressure from sudden release of the pressure plate 21 assembly 20, lowering the risk of accidental injury during operation and enhancing the safety of the testing operation.

[0050] In some testing scenarios, it is necessary to apply a continuous and constant compressive force to the rubber seal. In this case, the elastic element can continuously apply a certain preload, and even if the external environment changes, it can maintain a constant pressure on the seal by the pressure plate 21 through its own elastic adjustment, ensuring the consistency of the test conditions.

[0051] In this embodiment, the elastic element is a spring.

[0052] In some embodiments, each placement area includes a plurality of placement positions spaced apart for placing a plurality of seals to be tested 1 correspondingly on the plurality of placement positions; the compression part is a compression block protruding from the pressure plate 21 on the side surface facing the base plate 10, for pressing the seals to be tested 1 located at the plurality of placement positions by the compression block. The size of the compression block needs to be large enough to prevent the seals to be tested 1 from leaking out after being compressed to a preset compression amount.

[0053] The aforementioned setup, with its multiple spaced placement positions, allows for simultaneous pressure testing of multiple seals 1 with different preset compression values, and also enables simultaneous pressure testing of multiple seals 1 with a specific preset compression value across multiple placement positions, significantly improving testing efficiency. On photovoltaic module production lines, this batch testing capability is of great significance for accelerating product inspection processes and shortening production cycles. By rationally planning the layout of multiple placement positions, the number of test samples can be maximized within a limited space, simplifying the operation process and reducing the time operators spend testing individual samples. This is particularly effective when handling large batches of samples, significantly improving work efficiency.

[0054] Furthermore, each seal 1 under test has a corresponding compression block at its placement position. This means that the compression test of each seal can be conducted independently, unaffected by other samples, ensuring the consistency of test conditions and the accuracy of results for each sample. The protruding compression block design ensures that the compressive force is evenly distributed on the seal 1 under test during the compression process, reducing test errors caused by uneven pressure distribution, ensuring uniform deformation of the seal during compression, and improving the reliability of test data.

[0055] In some embodiments, the end face of the extrusion portion facing the seal 1 to be tested is provided with anti-slip texture.

[0056] In one embodiment of the adjustment component 30 of this application, a first connecting hole is provided on the base plate 10, and a second connecting hole 211 is provided on the pressure plate 21. The adjustment component 30 includes: a first connecting rod 31, at least a portion of the first connecting rod 31 is provided with an external thread section, and one end of the first connecting rod 31 is rotatably connected to the first connecting hole; a first adjustment knob 32, the other end of the first connecting rod 31 passes through the second connecting hole 211 and is connected to the first adjustment knob 32, and the external thread section on the first connecting rod 31 is threadedly connected to the second connecting hole 211.

[0057] Because the external threaded section on the first connecting rod 31 is threadedly connected to the second connecting hole 211 on the pressure plate 21, the operator can precisely control the lifting distance of the pressure plate 21 by rotating the first adjusting knob 32, thereby accurately adjusting the compression of the rubber seal. This fine-tuning capability is crucial for tests that require strict control of compression, ensuring the accuracy and repeatability of the test. The threaded connection provides a robust mechanical structure, ensuring that the pressure plate 21 will not experience unexpected displacement or shaking during the test. Especially when applying greater pressure, the connection between the pressure plate 21 and the base plate 10 is more stable, resulting in more reliable test results.

[0058] The combination of the first adjusting knob 32 and the first connecting rod 31 allows for convenient calibration and maintenance of the testing device. For example, if it is necessary to adjust the initial position of the pressure plate 21 or replace a damaged part, the operator only needs to adjust the knob or replace the corresponding connecting rod, without disassembling the entire device, thus simplifying the maintenance process. Furthermore, this connection method offers good compatibility; the first connecting rod 31 of different lengths or thread specifications can be replaced according to different testing requirements, thereby accommodating rubber seals of different sizes or achieving a wider range of compression adjustment.

[0059] In the second embodiment of the adjustment component 30 of this application, the adjustment component 30 includes: a connecting frame, one end of which is connected to the base plate 10, and the other end of which is located above the pressure plate 21, and a third connecting hole is provided on the connecting frame; a second connecting rod, at least a portion of which is provided with an external thread section, the second connecting rod passing through the third connecting hole and being threadedly connected thereto, a second adjustment knob being provided on the end of the second connecting rod away from the pressure plate 21, and the other end of the second connecting rod being rotatably connected to the pressure plate 21.

[0060] In the above configuration, the connecting frame serves as a support structure, stably fixed between the base plate 10 and the pressure plate 21. The second connecting rod is threaded to the third connecting hole on the connecting frame. This design ensures the verticality and stability of the pressure plate 21 during vertical movement, facilitating precise control of the compression amount by rotating the second connecting rod. The second adjustment knob allows the operator to easily rotate the second connecting rod to fine-tune the height of the pressure plate 21. This fine-tuning mechanism is not only easy to operate but also enables very precise adjustments, ensuring that the seal 1 under test withstands accurate pressure.

[0061] Furthermore, the connecting frame is connected to the pressure plate 21 via a second connecting rod, and with the addition of a threaded adjustment mechanism, the position of the pressure plate 21 can be quickly adjusted. This efficient adjustment mechanism can significantly improve testing efficiency, especially when multiple tests or continuous testing of multiple samples is required. Simultaneously, the second adjustment knob makes operation more intuitive and convenient; the operator can easily adjust the height of the pressure plate 21 simply by rotating it, without the need for complex tools or cumbersome processes, thus improving testing efficiency.

[0062] In some embodiments, the rubber seal pressure resistance testing device further includes: at least one compression detection element 50, which is disposed on the base plate 10 in a one-to-one correspondence with at least one pressure plate 21, for displaying in real time the preset compression amount of the seal 1 to be tested located on the base plate 10.

[0063] Thus, the real-time display function of the compression measurement device 50 allows the operator to continuously monitor the compression of the rubber seal during the test, ensuring it remains within the preset test standard range, thereby improving the accuracy and reliability of the test. The automatic reading and display of compression by the compression measurement device 50 reduces errors caused by manual measurement and judgment, ensuring the consistency and objectivity of the test data. Furthermore, real-time compression data helps the operator optimize test parameters based on test feedback, such as adjusting the descent speed of the pressure plate 21 or the magnitude of the compression force, to achieve more ideal aging test results. Without the need to stop the test for manual measurement, the real-time feedback from the compression measurement device 50 speeds up the testing process, especially in situations requiring frequent adjustments to the compression for comparative tests, where this function greatly improves work efficiency.

[0064] In some embodiments, the compression detection element 50 includes: a scale 51, one end of which is perpendicular to the base plate 10, and the other end of which touches the side of the pressure plate 21. The scale 51 has scale lines, and the scale value of the scale lines gradually increases along the direction from the base plate 10 to the pressure plate 21.

[0065] With the above setup, the scale lines on the graduated scale 51 can intuitively display the compression amount of the rubber seal during the descent of the pressure plate 21. The operator can easily read the specific compression value to ensure that the compression amount of the corresponding seal 1 under test has reached the preset compression amount. Since the scale values ​​are precisely calibrated, this design helps to improve the accuracy of the test. The operator can accurately control the descent distance of the pressure plate 21 according to the reading on the graduated scale 51 to ensure that the rubber seal reaches the preset compression amount during the compression test, thereby obtaining reliable test data.

[0066] The scale 51 is simple and intuitive, allowing operators to read and adjust the compression amount without the need for complex instruments or tools. This ease of use not only improves testing efficiency but also reduces the operator's workload during the testing process. Furthermore, during testing, the scale 51 can display changes in compression amount in real time, enabling operators to adjust the position of the pressure plate 21 immediately, avoiding test failures due to insufficient or excessive compression and ensuring the validity of the test results.

[0067] In some embodiments, both the base plate 10 and the pressure plate 21 are made of high-temperature resistant material.

[0068] Thus, according to the test requirements, the compressed test device must be placed in a high-temperature environmental test chamber for high-temperature aging tests. The use of high-temperature resistant materials ensures that the base plate 10 and pressure plate 21 can maintain structural integrity and functional stability under high-temperature environments, avoiding test failures caused by material softening, deformation, or damage, and ensuring the accuracy and reliability of test results. Furthermore, the high-temperature resistant material has high thermal stability and can resist performance degradation under long-term high temperatures. This means that the base plate 10 and pressure plate 21 can still maintain good working condition after undergoing multiple high-temperature aging tests, extending the overall service life of the test device and reducing maintenance and replacement costs.

[0069] Furthermore, since the stability of materials at high temperatures directly affects the accuracy of the test, high-temperature resistant materials can reduce the impact of temperature changes on the test structure, ensuring that the compression force of the pressure plate 21 on the rubber seal remains constant under high-temperature conditions, thereby improving the accuracy and comparability of the test data. Simultaneously, during high-temperature aging tests, the base plate 10 and pressure plate 21, as key components directly exposed to the high-temperature environment, effectively prevent heat damage due to their high-temperature resistance, protecting operators from burns and other safety hazards, thus improving the safety of the testing process.

[0070] Those skilled in the art will understand that the above embodiments are specific examples of implementing this application, and in practical applications, various changes in form and detail can be made without departing from the spirit and scope of this application. Any person skilled in the art can make various alterations and modifications without departing from the spirit and scope of this application; therefore, the scope of protection of this application should be determined by the scope defined in the claims.
