Abstract
Description
Technical Field
[0001] This application relates to the technical field of testing instruments, and in particular to a multifunctional testing instrument. Background Technology
[0002] RTP (Resistant Pressure Test) is a sealing device used to isolate materials, commonly used for material input and output or for removing solid waste from a chamber. For ease of processing, the object under test is generally composed of two parts connected together. To ensure the airtightness of the object, it is necessary to inspect the connection point between these two parts.
[0003] In existing testing instruments, the object to be tested is mounted on the instrument, and an inflation chamber is formed between the object and the instrument. Air is inflated into the chamber, and a pressure sensor inside the instrument determines whether the object is leaking. However, because different batches of objects have different models and sizes, the existing testing instruments are only compatible with one model of object, resulting in low compatibility and requiring improvement. Utility Model Content
[0004] The purpose of this application is to provide a multifunctional testing instrument to adapt to more different models of objects to be tested.
[0005] The multifunctional testing instrument provided in this application adopts the following technical solution: it includes a testing host, a testing cover plate sleeved on the testing host, and a fixed shell detachably connected to the testing host. When the testing cover plate and the fixed shell are both installed on the testing host, the testing cover plate is clamped by the fixed shell and the testing host. The testing cover plate is used to connect with the object to be tested. A sealing component is connected to the testing end face of the testing cover plate. The testing host, the testing cover plate, and the fixed shell are all provided with an inflation area. A first inflation / deflation structure and a pressure sensor are connected within the inflation area.
[0006] By adopting the above technical solution, when different types of test objects need to be tested, the fixing shell can be disassembled from the test host, separating the fixing shell from the test cover plate. This allows for the replacement of different types of test cover plates, making it suitable for different models of test objects. The cooperative design of the test host, test cover plate, and fixing shell enables effective clamping of the test cover plate, ensuring a stable connection. The sealing components on the test cover plate further improve the sealing performance between the test object and the test object, effectively preventing gas leakage. When the test object is installed on the test cover plate, it covers the inflation area, thus forming an inflation chamber. The combined use of the inflation area, the first inflation / deflation structure, and the pressure sensor enables precise control and monitoring of the air pressure inside the inflation chamber, thereby accurately determining whether there is any air leakage in the test object.
[0007] Optionally, the first inflation / deflation structure includes a first air pipe and a first air pump connected to the test host, the first air pipe being connected to the first air pump and communicating with the inflation area.
[0008] By adopting the above technical solution, the design of the first air pipe and the first air pump enables controllable inflation and deflation of gas in the inflation area, thereby ensuring a stable inflation environment between the object under test and the test cover. This simplifies the operation process and improves testing efficiency.
[0009] Optionally, the mounting housing is threadedly connected to the test host.
[0010] By adopting the above technical solution, the threaded connection between the fixed shell and the test host enables rapid assembly and disassembly of both, making the operation simple and convenient. At the same time, this connection method has high reliability, maintaining good sealing performance during testing and avoiding gas leakage problems caused by loose connections.
[0011] Optionally, the outer surface of the fixing shell is provided with a chamfer.
[0012] By adopting the above technical solutions, chamfering can effectively reduce stress concentration, lower the risk of injury caused by sharp edges, and protect operators.
[0013] Optionally, the sealing assembly includes an inflatable sealing ring connected to the test cover plate and a second inflation structure for inflating or deflating the inflatable sealing ring.
[0014] By adopting the above technical solution, the inflatable sealing ring can form a flexible seal when in contact with the object under test, adapting to different shapes and sizes of the object under test and improving the adaptability of the equipment. The second inflation structure effectively improves the accuracy and efficiency of airtightness testing by precisely controlling the inflation or deflation of the inflatable sealing ring.
[0015] Optionally, the test cover plate is provided with a mounting ring groove for the inflatable sealing ring to engage.
[0016] By adopting the above technical solution, stable positioning of the inflatable sealing ring can be achieved, avoiding a decrease in sealing performance due to positional deviation during testing. Simultaneously, this design simplifies the assembly process of the inflatable sealing ring and improves assembly efficiency. The inflatable sealing ring fits snugly against the inner wall of the mounting groove, increasing the gas movement path and thus ensuring the accuracy of the airtightness test.
[0017] Optionally, the sealing assembly further includes an air inlet pipe connected to the inflatable sealing ring, the test cover plate is provided with a connection channel communicating with the air inlet pipe, the second inflation structure is connected to the test host, and the second inflation structure communicates with the connection channel.
[0018] By adopting the above technical solution, connecting the inflatable sealing ring to the air inlet pipe, and setting up a connecting channel and a second inflation structure to cooperate with it, gas can smoothly enter or exit the inflatable sealing ring, thereby ensuring a tight fit and effective seal at the joint of the object under test. Simultaneously, the gas from the second inflation structure can enter the connecting channel of different test covers. This design simplifies the operation process and improves testing efficiency.
[0019] Optionally, the second inflation structure includes a second air pipe and a second air pump connected to the test host, the second air pipe being connected to the second air pump and communicating with the connection channel.
[0020] By adopting the above technical solution, the setting of the second air pipe and the second air pump enables the inflation sealing ring to achieve controllable inflation and deflation of gas, which can both seal the gap between the test cover and the object under test, and separate the inflation sealing ring from the object under test, making it easier to disassemble the object under test.
[0021] Optionally, the outer surface of the test host is connected to two sealing rings, which are used to seal the gap between the test host and the test cover plate. When the test cover plate is installed on the test host, the connection channel is located between the two sealing rings.
[0022] By adopting the above technical solution, one sealing ring prevents gas in the inflation chamber from entering the connection channel through the gap between the test host and the test cover plate, thus avoiding affecting the detection effect of the object under test. The other sealing ring prevents gas in the connection channel from leaking through the gap between the test host and the test cover plate, allowing gas to smoothly fill the inflation sealing ring.
[0023] Optionally, the test host is provided with a limiting ring groove for the sealing ring to be engaged.
[0024] By adopting the above technical solution, the limiting ring groove can accurately position the sealing ring, ensuring stable installation and avoiding sealing failure due to positional misalignment. Furthermore, this design enhances the sealing performance between the test host and the test cover, effectively preventing gas leakage and thus improving the accuracy of the airtightness test.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. When different types of test objects need to be tested, remove the fixing shell from the test host to separate the fixing shell from the test cover plate, so that different types of test cover plates can be replaced, thus making it suitable for different models of test objects.
[0027] 2. The threaded connection between the fixed housing and the test host allows for quick assembly and disassembly, making operation simple and convenient. Furthermore, this connection method offers high reliability, maintaining a good seal during testing and preventing gas leakage due to loose connections. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.
[0035] This application discloses a multifunctional testing instrument.
[0036] Combination Figure 1 and Figure 2 As shown, the system includes a test host 1, a test cover 2 fitted onto the test host 1, and a fixing shell 3 threadedly connected to the test host 1. The outer surface of the fixing shell 3 has a chamfer. When both the test cover 2 and the fixing shell 3 are connected to the test host 1, the test cover 2 is clamped between the fixing shell 3 and the test host 1. An identification chip is fixedly connected inside the test host 1. When the object to be tested is mounted on the test cover 2, the identification chip can identify the model of the object to be tested.
[0037] Combination Figure 3 , Figure 4 and Figure 5As shown, the test host 1, test cover 2, and fixed shell 3 all have inflation areas 11. When the object to be tested is installed on the test cover 2, the test cover 2 covers the inflation area 11, and the test cover 2, test host 1, test cover 2, and fixed shell 3 form an inflation cavity. The test host 1 is connected to a pressure sensor (not shown in the attached figure) and a first inflation / deflation structure 4. The pressure sensor is located within the inflation area 11. The first inflation / deflation structure 4 includes a first air pipe 41 and a first air pump (not shown in the attached figure) fixedly connected to the test host 1. The first air pipe 41 is fixedly connected to the first air pump and communicates with the inflation area 11.
[0038] Combination Figure 3 , Figure 4 and Figure 5 As shown, a sealing assembly 5 is connected to the test end face of the test cover plate 2. The sealing assembly 5 includes an inflatable sealing ring 51 connected to the test cover plate 2, an air inlet pipe 52 connected to the inflatable sealing ring 51, and a second inflation structure 53 connected to the test host 1. The test cover plate 2 has an installation ring groove 21 for the inflatable sealing ring 51 to be inserted and a receiving groove 22 for the air inlet pipe 52 to be inserted. The installation ring groove 21 communicates with the receiving groove 22, and the outer surface of the air inlet pipe 52 is fixedly connected to the inner wall of the receiving groove 22. The test cover plate 2 has a connecting channel 23, which communicates with the air inlet pipe 52. The second inflation structure 53 includes a second air pipe 531 and a second air pump (not shown in the attached figure) fixedly connected to the test host 1. The second air pipe 531 is fixedly connected to the second air pump and communicates with the connecting channel 23. Two sealing rings 6 are fitted onto the outer surface of the test host 1. Two limiting ring grooves 12 are formed on the outer circumference of the test host 1 for the corresponding sealing rings 6 to engage. Each sealing ring 6 corresponds to one limiting ring groove 12. Both sealing rings 6 seal the gap between the test host 1 and the test cover plate 2. When the test cover plate 2 is installed on the test host 1, the connecting channel 23 is located between the two sealing rings 6.
[0039] The implementation principle of a multifunctional tester according to an embodiment of this application is as follows:
[0040] After the object to be tested is installed on the test cover plate 2, the second air tube 531 inflates the inflation sealing ring 51. The inflation sealing ring 51 expands and comes into contact with the object to be tested, thereby sealing the gap between the test cover plate 2 and the object to be tested. The first air tube 41 inflates the inflation chamber, and the air pressure sensor detects the air pressure in the inflation chamber; or the first air tube 41 evacuates air from the inflation chamber, and the air pressure sensor detects the air pressure in the inflation chamber. Positive pressure testing or negative pressure testing is used to determine whether there is air leakage in the object to be tested.
[0041] The object to be tested can also be a ring and a glove fixedly connected to the ring. The test cover 2 is fixedly connected to the ring, and the first air tube 41 inflates the air chamber. The gas passes through the ring and enters the glove, thereby determining whether the glove leaks. This multifunctional tester can identify various test objects and test the sealing performance of various test objects (such as RTP, gloves, etc.).
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
