Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and more specifically to multifunctional testing equipment. Background Technology

[0002] Experimental equipment refers to the devices or tools used to conduct various scientific, engineering, or technological experiments. They are designed and constructed with different functions and characteristics according to the different goals and requirements of the experiments. The purpose of experimental equipment is to help researchers obtain accurate data and conclusions by controlling experimental conditions, measuring experimental data, verifying hypotheses, or testing material properties.

[0003] Current testing equipment, such as carbonization test chambers, high-temperature curing test chambers, and vacuum test chambers, can only perform a single test condition. When a sample mold needs to undergo two or more tests simultaneously, the existing testing equipment cannot meet the requirements, thus limiting the scope of application of the testing equipment. Summary of the Invention

[0004] In view of this, the present invention provides a multifunctional testing device to solve the problem that existing testing devices cannot meet the needs of various testing molds, thus limiting the scope of application of the testing devices.

[0005] This invention provides a multifunctional testing device, comprising:

[0006] The chamber has a closed test chamber inside. An air inlet assembly and an air outlet assembly are respectively provided on opposite sides along the length of the chamber. A pressurizing assembly is provided on the top of the chamber. The pressurizing end of the pressurizing assembly is located inside the test chamber, and a first fixing member is provided on the pressurizing end. The first fixing member is adapted to be fixedly connected to the top of the sample template. The air inlet assembly and the air outlet assembly are respectively connected to the test chamber. Multiple heating plates are also spaced apart inside the chamber.

[0007] A rotating assembly includes a rotating shaft and a driving component connected to the rotating shaft. The rotating shaft is located at the bottom of the housing and inside the test chamber.

[0008] A support assembly, located at the top of the rotating shaft, is suitable for placing the sample mold.

[0009] Beneficial Effects: The multifunctional testing equipment provided by this invention, by integrating an air inlet assembly, an air outlet assembly, a pressurizing assembly, and a heating plate on the chamber, can conduct tests by introducing various gases into the sample mold within the chamber, applying various pressures, and controlling the test temperature. Furthermore, by closing the air inlet assembly and opening the air outlet assembly, the gas within the test chamber can be extracted, creating a vacuum environment for vacuum testing. This meets various testing conditions and has a wide range of applications. The air inlet and air outlet assemblies are located on opposite sides along the length of the chamber, facilitating the air permeation test of the sample mold. The pressurizing assembly and support assembly are located on the upper and lower sides of the sample mold, respectively, to apply pressure to the sample mold for pressure testing with minimal impact on the air permeation test.

[0010] In one optional embodiment, the support assembly includes a support body and a second fixing member detachably disposed on the support body. The bottom of the support body is detachably connected to the rotating shaft. In a pressurized state, the top of the sample mold is connected to the first fixing member, and the bottom is connected to the second fixing member.

[0011] Beneficial effects: When it is necessary to pressurize the sample mold, the second fixing part is first installed on the support body.

Then, the pressurizing component is controlled to apply pressure to the sample mold. The structure is stable and highly reliable.

[0012] In one alternative embodiment, the support assembly includes a tray detachably mounted on the support body, wherein in a non-pressurized state, the top of the sample mold is suspended and the bottom is placed on the tray.

[0013] Beneficial effect: When it is not necessary to pressurize the sample mold, there is no need to fix the sample mold. First, install a tray on the support body, and place the sample mold directly on the tray so that other tests can be carried out on the sample, avoiding the influence of the fixing parts on the test results.

[0014] In one optional embodiment, the system further includes a plurality of support plates disposed on the inner side of the box body. The plurality of support plates are arranged in pairs, with the pairs of support plates disposed opposite each other on the inner side of the box body. The pairs of support plates are detachably provided with shelves.

[0015] Beneficial effects: Pairs of support plates are used to mount shelves, which are then used to hold sample molds, trays, or other test samples, further expanding the application range of the multifunctional testing equipment and facilitating its widespread use. Multiple pairs of support plates can simultaneously hold multiple shelves, allowing for the simultaneous testing of multiple sample molds, trays, or other test samples.

[0016] In one optional embodiment, the housing is further provided with a vacuum assembly that communicates with the test chamber.

[0017] Beneficial effects: The vacuum assembly enables the evacuation of the test chamber to meet vacuum testing conditions, thereby further expanding the application range of the multifunctional testing equipment. The vacuum assembly can also be connected to the inlet and outlet assemblies to achieve vacuuming, reducing installation difficulty and lowering operating costs.

[0018] In one alternative embodiment, a sensor assembly and a lighting lamp are spaced apart inside the housing, and the sensor assembly includes at least one of a temperature sensor, a pressure sensor, and a vacuum sensor.

[0020] In one optional embodiment, the housing is further provided with a paperless recorder, a temperature dial, a pressure dial, and a vacuum dial, and the sensor assembly, the lighting lamp, the temperature dial, the pressure dial, and the vacuum dial are respectively electrically connected to the paperless recorder.

[0021] Beneficial effects: By setting up temperature, pressure, and vacuum gauges, operators can easily obtain parameters such as temperature, pressure, and vacuum levels in real time during the experiment. The paperless recorder facilitates the recording of these parameters for subsequent experimental analysis.

[0022] In one alternative embodiment, a control panel is provided on one side of the housing, and the sensor assembly is also electrically connected to the control panel. The control panel integrates a display, a timer, and a switch assembly. The display includes at least one of a temperature display, a pressure display, and a vacuum display. The switch assembly is electrically connected to the display and / or the sensor assembly.

[0023] Beneficial effects: Parameters such as temperature, pressure, and vacuum collected during the experiment can be displayed in real time on the control panel for easy viewing by staff. The switch assembly is used to turn the display and / or sensor assembly on or off.

[0024] In one optional embodiment, the box body is provided with an openable door on the side where the control panel is located. The door is provided with a viewing window and a rotating handle, and a door lock is provided between the door and the box body.

[0025] Beneficial effects: The rotating handle makes it easy to open and close the chamber door, and the viewing window on the door allows staff to observe the sample molds during the experiment without opening the door, avoiding the impact of environmental fluctuations on the experiment and improving experimental efficiency and safety.

[0026] In one alternative embodiment, a sealing element is provided between the inner wall of the box and the box door.

[0027] Beneficial effects: By installing a sealing element between the inner wall of the chamber and the door, the airtightness of the test chamber can be guaranteed, ensuring the reliability of the test. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0036] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0037] According to an embodiment of the present invention, a multifunctional testing device is provided, comprising: a housing 1, a rotating assembly 5, and a supporting assembly 6. The housing 1 has a closed testing chamber inside. An air inlet assembly 2 and an air outlet assembly 3 are respectively provided on opposite sides of the housing 1 along its length. A pressurizing assembly 4 is provided at the top of the housing 1. The pressurizing end of the pressurizing assembly 4 is located inside the testing chamber, and a first fixing member is provided on the pressurizing end. The first fixing member is adapted to be fixedly connected to the top of a sample template. The air inlet assembly 2 and the air outlet assembly 3 are respectively connected to the testing chamber. Multiple heating plates are also spaced apart inside the housing 1. The rotating assembly 5 includes a rotating shaft and a driving component connected to the rotating shaft. The rotating shaft is located at the bottom of the housing 1 and inside the testing chamber. The supporting assembly 6 is located at the top of the rotating shaft and is adapted to place the sample template.

[0038] Therefore, the multifunctional testing equipment provided in this embodiment of the invention, by integrating an air inlet assembly 2, an air outlet assembly 3, and a pressurizing assembly 4 on the housing 1, can introduce various gases into the sample mold inside the testing chamber of the housing 1 for testing, apply various pressures for testing, and control the testing temperature. Furthermore, by closing the air inlet assembly 2 and opening the air outlet assembly 3, the gas inside the testing chamber can be extracted, creating a vacuum environment for vacuum testing. This meets various testing conditions and has a wide range of applications. The air inlet assembly 2 and the air outlet assembly 3 are located on opposite sides along the length of the housing 1, facilitating the ventilation testing of the sample mold. The pressurizing assembly 4 and the support assembly 6 are respectively located on the upper and lower sides of the sample mold to apply pressure to the sample mold for pressure testing, with minimal impact on the ventilation testing. When the pressurizing assembly 4 is not needed, the rotating assembly 5 can also drive the support assembly 6 to rotate, thereby rotating the sample mold and facilitating tests such as drying and heating of the sample.

[0039] Specifically, the air intake assembly 2 is used to introduce the required gas, such as air, carbon dioxide, nitrogen, or argon, into the test chamber. The air exhaust assembly 3 is used to exhaust the gas from the test chamber. The air intake assembly 2 is equipped with an air inlet, an air inlet valve, and an air inlet pump. The air inlet is connected to the test chamber, and the air inlet is connected to the air inlet pump through the air inlet valve. The air inlet pump provides power, and the air inlet valve regulates the flow rate of the gas introduced through the air inlet.

[0040] Similarly, the air outlet assembly 3 is equipped with an air outlet, an air outlet valve, and an air outlet pump. The air outlet is connected to the test chamber, and the air outlet is connected to the air outlet pump through the air outlet valve. The air outlet pump is used to provide power, and the air outlet valve is used to regulate the gas flow rate discharged from the air outlet.

[0041] like Figure 1 and Figure 4 As shown, the pressurizing assembly 4 is used to apply pressure to the sample mold. It includes a pressure rod and a regulating valve connected to it. The pressure rod is located inside the housing 1, the regulating valve is located outside the pressure rod, and a first fixing member is located on the pressure rod. The first fixing member can be a slot. The pressure on the sample mold is adjusted by rotating the regulating valve to move the pressure rod up and down. When the pressurizing assembly 4 applies pressure to the sample mold, the sample mold needs to be fixed between the pressurizing assembly 4 and the support assembly 6 beforehand. The driving component of the rotating assembly 5 can be a conventional driving component such as a motor or cylinder.

[0042] It should be noted that the sample molds in the embodiments of the present invention include, but are not limited to, cement paste molds, mortar molds, etc.

[0043] In one embodiment, the support assembly 6 includes a support body and a second fastener detachably disposed on the support body. The second fastener may also be a slot structure. The bottom of the support body is detachably connected to the rotating shaft. In the pressurized state, the top of the sample mold is connected to the first fastener, and the bottom is connected to the second fastener.

[0044] When it is necessary to pressurize the sample mold, the second fixing component is first installed on the support body. The top of the sample mold is connected to the first fixing component, and the bottom is connected to the second fixing component to fix the support body. Then, the pressurizing component 4 is controlled to apply pressure to the sample mold. The structure is stable and highly reliable.

[0045] It should be noted that the embodiments of the present invention do not limit the detachable connection method between the support body and the second fixing member. For example, a snap-fit ​​can be used for quick installation, or a threaded connection can be used for a secure connection. Similarly, the detachable connection method between the support body and the rotating shaft is not limited.

[0046] In one embodiment, the support assembly 6 includes a tray detachably mounted on the support body. In the non-pressurized state, the top of the sample mold is suspended, and the bottom rests on the tray. When it is not necessary to pressurize the sample mold, there is no need to fix the sample mold. The tray is first installed on the support body, and the sample mold is placed directly on the tray to allow for other tests on the sample, avoiding the influence of the fixing components on the test results.

[0047] It should be noted that the embodiments of the present invention do not limit the detachable connection form between the support body and the tray. For example, snap-fit ​​and slot connection can be used for quick installation, or threaded connection can be used for a firm connection.

[0048] Furthermore, the support body can be fixed to the second fastener and the tray using the same detachable structure. For example, a slot can be provided on the top surface of the support body, and corresponding buckles can be provided on the bottom of the tray and the second fastener. By engaging the buckles with the slots, either the tray or the second fastener can be installed on the support body.

[0049] In one embodiment, such as Figure 3 As shown, the multifunctional testing equipment also includes multiple support plates 7 located inside the housing 1. These support plates 7 are arranged in pairs, facing each other inside the housing 1. Each pair of support plates 7 is detachably equipped with a shelf. The paired support plates 7 are used to mount the shelf, which is used to place sample molds, trays, or other test samples, further expanding the application range of the multifunctional testing equipment and facilitating its widespread use. Multiple pairs of support plates 7 can simultaneously hold multiple shelves, allowing for simultaneous testing of multiple sample molds, trays, or other test samples.

[0050] It should be noted that the embodiments of the present invention do not restrict the detachable connection between the support plate 7 and the shelf. For example, the support plate 7 can be connected to the shelf by buckles and slots to quickly install and remove the shelf, or the shelf can be placed directly on the pair of support plates 7 for use.

[0051] In one embodiment, the housing 1 is further equipped with a vacuum pumping assembly communicating with the test chamber. The vacuum pumping assembly allows for evacuation of the test chamber in housing 1 to meet vacuum test conditions, thereby integrating multiple test conditions such as vacuum, heating, pressurization, and ventilation, further expanding the application range of the multifunctional test equipment. The vacuum pumping assembly can consist of a vacuum pump and a gas delivery pipe. The gas delivery pipe is located inside the test chamber, and the vacuum pump extracts gas from the test chamber through the gas delivery pipe to create a vacuum environment within the test chamber. Of course, other conventional vacuum pumping assemblies can also be selected as needed; this embodiment of the invention does not impose excessive limitations on this.

[0052] In addition, the vacuum pumping assembly can also be connected to the air inlet assembly 2 and the air outlet assembly 3. For example, the vacuum pump can be connected to the air outlet assembly 3 to achieve vacuuming in conjunction with the air inlet assembly 2 and the air outlet assembly 3, thereby reducing the installation difficulty of the vacuum pumping assembly and also helping to reduce the cost of use.

[0053] In one embodiment, a sensor assembly and a lighting fixture are spaced apart inside the housing 1. The sensor assembly includes at least one of a temperature sensor, a pressure sensor, and a vacuum sensor. The sensor assembly facilitates the collection of parameters such as temperature, pressure, and vacuum level of the sample mold during the experiment, enabling subsequent experimental analysis. The lighting fixture provides sufficient illumination for personnel to observe the sample mold during the experiment.

[0054] Furthermore, in one embodiment, the housing 1 is also equipped with a paperless recorder, a temperature dial, a pressure dial, and a vacuum dial. The sensor assembly, lighting, temperature dial, pressure dial, and vacuum dial are electrically connected to the paperless recorder. By setting up the temperature dial, pressure dial, and vacuum dial, operators can easily obtain parameters such as temperature, pressure, and vacuum level during the experiment in real time. The paperless recorder facilitates the recording of parameters such as temperature, pressure, and vacuum level during the experiment for subsequent experimental analysis.

[0055] In one embodiment, such as Figure 2 As shown, a control panel is located on one side of the housing 1. The sensor assembly is also electrically connected to the control panel. The control panel integrates a display 8, a timer 9, and a switch assembly 10. The display 8 includes at least one of a temperature display 801, a pressure display 802, and a vacuum display 803. The switch assembly 10 is electrically connected to the display 8 and / or the sensor assembly. Parameters such as temperature, pressure, and vacuum collected during the test can be displayed on the control panel in real time for easy viewing by personnel. The switch assembly 10 is used to turn the display 8 and / or the sensor assembly on or off.

[0056] In one embodiment, such as Figure 1 and Figure 2 As shown, the side of the enclosure 1 with the control panel also has an openable door 101. The door 101 has a viewing window 102 and a rotating handle 103. A door lock is also provided between the door 101 and the enclosure 1. The rotating handle 103 facilitates opening and closing the door 101. The viewing window 102 on the door 101 allows staff to observe the sample mold during the experiment without opening the door 101, avoiding the impact of environmental fluctuations on the experiment and improving experimental efficiency and safety.

[0057] Specifically, both the door 101 and the control panel are located on the front side of the enclosure 1 for use by staff, with the control panel located on the lower side of the enclosure 1.

[0058] Furthermore, the door 101 and the viewing window 102 are integrated, meaning that the entire door 101 is made of transparent material and can serve as the viewing window 102. The transparent material can be tempered glass, acrylic glass, etc.

[0059] In one embodiment, a sealing element is provided between the inner wall of the chamber 1 and the door 101. By providing a sealing element between the inner wall of the chamber 1 and the door 101, the airtightness of the test chamber can be ensured, thus guaranteeing the reliability of the test. The sealing element can be a conventional sealing element such as a sealing strip or a sealing ring.

[0060] To achieve the basic functions of the multifunctional testing equipment, the multifunctional testing equipment in this embodiment may also include other necessary modules or components, such as wires, fasteners, etc. It should be noted that the other necessary modules or components included in the multifunctional testing equipment can be any suitable existing structure.
