The sealing cover plate 80 is movably connected between the box body 10 and is used to open and close the observation window 70. It can be understood that by arranging the observation window 70, the operator can detect the heat curing process of the sensitive material from the visual angle in real time without affecting the heat curing process, and observe the sample morphology, color change, foaming, desorption and other states, so as to adjust and control the heat curing process parameters in time based on the window effect. At the same time, the observation window 70 is sealed by the sealing cover plate 80, of course, when the user does not need to observe, the sealing cover plate 80 can be covered on the observation window 70, so as to avoid the heat in the accommodating cavity 11 from flowing out through the observation window 70. When the user needs to observe, the sealing cover plate 80 can be opened, and the current heat curing state of the sensitive material in the accommodating cavity 11 can be observed through the high-temperature-resistant transparent plate 71, and the use is more convenient.
[0072] Further, in the height direction Z of the box body 10, the observation window 70 is arranged at the top of the box body 10. In this way, the operator can observe the change of the sensitive material from the overhead angle, so that the visual range is wider, and the use and observation are more convenient.
[0073] The high-temperature-resistant transparent plate 71 can be a quartz glass, a high-silica glass, or the like.
[0074] Please continue to refer to Figure 1 The sealing cover plate 80 is rotatably connected to the box body 10 by a hinge. This structure is simple, low in cost, and convenient to use. Alternatively, the sealing cover plate 80 is rotatably connected to the box body 10 by a rotating shaft.
[0075] Further, as Figure 8 shown, the sealing cover plate 80 includes a main body 81 and a heat-insulating layer 82. The main body 81 is movably connected to the box body 10, and the heat-insulating layer 82 is arranged in the main body 81 to improve the heat-insulating effect of the main body 81. Here, the heat-insulating layer 82 is made of a heat-insulating sensitive material, such as a ceramic fiber blanket, a polycrystalline alumina fiber, a chromium-containing fiber blanket, or the like.
[0076] The sealing cover plate 80 is provided with a handle 83. Here, the handle 83 is used for an operator to hold to control the opening and closing of the sealing cover plate 80 to the observation window 70. It should be explained that the form of the handle 83 is not limited, which can be a groove, a protrusion, or a similar door handle, which is not limited here.
[0077] In an embodiment, the experimental online heat curing evaluation device 100 further includes an illuminating lamp arranged in the accommodating cavity 11 for illuminating the inside of the accommodating cavity 11, so as to facilitate an observer to observe the change of the sensitive material through the high-temperature-resistant transparent plate 71.
[0078] Here, the illuminating lamp can be a constant light, or the switch of the illuminating lamp can be associated with the opening and closing of the sealing cover plate 80, that is, when the sealing cover plate 80 is opened, the illuminating lamp is turned on; when the sealing cover plate 80 is closed, the illuminating lamp is turned off. Specifically, the opening and closing of the sealing cover plate 80 can be detected by a sensor, and then the signal of the sensor is used to control the switch of the illuminating lamp. At the same time, since the inside of the accommodating cavity 11 is a high-temperature environment, the illuminating lamp is also selected to be a high-temperature-resistant lamp.
[0079] Please continue to refer to Figures 1 to 3 The experimental online heat curing evaluation device 100 further includes a caster 200 arranged at the bottom of the box body 10 in the height direction Z of the box body 10. In this way, under the action of the caster 200, the experimental online heat curing evaluation device 100 can be conveniently deployed and moved inside a clean room or a scientific research platform, and the use is more flexible and variable.
[0080] In an embodiment, after the experimental online thermal curing evaluation device 100 is moved into position, in order to facilitate the adjustment and use of the experimental online thermal curing evaluation device 100. The application is also provided with a horizontal adjustment mechanism, which can adjust the caster 200 through the horizontal adjustment mechanism, so that the position of the experimental online thermal curing evaluation device 100 after moving is relatively horizontal and stable. Here, the horizontal adjustment mechanism can be set as a lifting mechanism, so as to realize the adjustment of the position of the caster 200 through the lifting mode; of course, not limited to this, the horizontal adjustment mechanism can also be other mechanisms that can realize the horizontal position adjustment, which will not be described here.
[0081] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.
[0082] The above-mentioned embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
