Description

Technical Field

[0001] This utility model relates to the field of environmental testing, specifically to a rapid environmental test chamber employing multiple drawer-type trays. Background Technology

[0002] An environmental test chamber is a testing device used to simulate various environmental conditions. It is widely used in industries such as scientific research, aerospace, automotive, electronics, and chemicals to perform performance testing and reliability assessments on products. The main function of an environmental test chamber is to simulate the effects of different environmental factors on products under controlled conditions in order to test the product's performance in actual use environments.

[0003] Environmental test chambers have some shortcomings in practical applications, specifically in the following aspects:

[0004] First, setting up an environmental test chamber takes a considerable amount of time. This is because the real-world environment that the test chamber needs to simulate is quite complex, including various factors such as temperature, humidity, and air pressure, which means that adjusting the internal environment of the chamber requires time. Secondly, to ensure the accuracy of the test results, the environmental chamber requires high stability; therefore, establishing a suitable environmental chamber takes a long time.

[0005] Secondly, the process of taking out and placing test samples requires opening and closing the environmental test chamber door. This process may have some impact on the environment inside the chamber, especially when the door is opened and closed frequently, which can affect the stability of the environment inside the chamber. Moreover, after opening and closing the door, the environmental chamber needs to re-establish the required environment, which also takes time.

[0006] Secondly, the connection of the test sample to the test harness needs to be performed inside the environmental test chamber. This means that during the test, the connection and adjustment of the test harness must be carried out inside the chamber, which undoubtedly increases the time cost. At the same time, since the connection and adjustment of the test harness requires a certain amount of operating space, this also makes the internal space requirements of the environmental test chamber higher, thus limiting the application range of the environmental test chamber. Summary of the Invention

[0007] In view of the deficiencies in the prior art, the purpose of this utility model is to provide a rapid environmental box that employs multiple drawer-type trays.

[0008] According to one aspect of the present invention, a rapid environment box employing multiple drawer-type trays is provided, including...

[0009] The enclosure has at least one opening.

[0010] A tray, used to hold test samples, is drawer-shaped and inserted into the opening;

[0011] The first thermal insulation barrier is disposed on the outside of the box body to cover the opening;

[0012] The second thermal insulation barrier is disposed inside the housing and is used to cover the opening.

[0013] Preferably, the housing has multiple openings, which are arranged in an array and are independent of each other.

[0014] Preferably, the tray includes:

[0015] A control panel is provided on the control panel;

[0016] The tray body is connected to the panel and is drawer-shaped.

[0017] The slide rails are disposed on both sides of the tray body.

[0018] Preferably, the outer surface of the panel is provided with a heat insulation layer.

[0019] Preferably, the opening is adapted to the size of the tray body.

[0020] Preferably, a connector is disposed on the outside of the panel, and the connector is connected to the test sample placed inside the tray body via a connecting cable.

[0021] Preferably, the first thermal insulation barrier is a plate-shaped structure, which is installed around the opening on the outside of the box to form an opening and closing structure; the second thermal insulation barrier is a plate-shaped structure, which is installed around the opening on the inside of the box to form an opening and closing structure.

[0022] Preferably, the outer shell of the first or second thermal insulation barrier is made of metal or engineering plastic, and the inner shell is made of polyurethane foam, polystyrene foam or rock wool.

[0023] Preferably, the size of the first or second thermal insulation barrier is larger than the size of the opening.

[0024] Preferably, the first thermal insulation barrier is connected to the box body by means of hinge or fastener; the second thermal insulation barrier is connected to the box body by means of hinge.

[0025] Compared with the prior art, the present invention has the following beneficial effect:

[0026] This invention provides a rapid environmental chamber employing multiple drawer-type trays. Thermal insulation measures are added both inside and outside the openings. The chamber is only opened for the brief moment a sample tray is inserted or removed; otherwise, it remains sealed to maintain the temperature. Specifically, for openings without trays, the first and second thermal insulation barriers seal the opening; for openings with trays, the tray itself seals the opening. Even with short-term tray insertion and removal, the overall internal condition of the environmental chamber remains unchanged.

[0027] An embodiment of this utility model provides a rapid environmental chamber employing multiple drawer-type trays. Connectors can be configured on the tray panels to connect to the sample being tested. The insertion and removal of the connectors are performed outside the environmental chamber, eliminating the need for operation inside the chamber and further reducing the impact on the environment.

[0028] The embodiments of this utility model address two aspects: reducing door opening and closing time and increasing insulation measures, so that the overall state of the rapid environmental chamber remains unchanged. Attached Figure Description

[0038] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0039] like Figure 1 As shown, in one embodiment of this utility model, a rapid environmental protection box employing multiple drawer-type trays is provided, comprising a box body 1, a tray 2, a first thermal insulation barrier 3, and a second thermal insulation barrier 4. The box body 1 has at least one opening; the tray 2 is drawer-shaped and inserted into the opening; the first thermal insulation barrier 3 is disposed on the outside of the box body to cover the opening; the second thermal insulation barrier 4 is disposed inside the box body to cover the opening.

[0040] This embodiment uses multiple drawer-type trays to hold samples. While one tray is being moved in or out, the samples on the other trays can continue to be tested in the environment without affecting the experimental process. Insulated barriers are installed before and after the opening in the chamber. These barriers only open when a sample tray is being moved in or out, and remain sealed at other times. Even if a tray is being moved in or out, the overall state inside the environmental chamber remains unchanged.

[0041] In one preferred embodiment, to improve the space utilization of the environmental test chamber, multiple rectangular openings are made on the chamber body 1, and the multiple openings are distributed in an array. Each opening corresponds to a tray. Of course, in other embodiments, the multiple openings can also be distributed in other shapes.

[0042] Based on the openings in the above embodiments, in a preferred embodiment, a tray structure adapted to them is provided. For example... Figure 4 As shown, tray 2 includes a panel 21, a tray body 22, and a slide rail 23. The panel 21 has an operating handle 27; the tray body 22 is connected to the panel 21 and is drawer-shaped; the slide rail 23 is located on both sides of the tray body 22. The slide rail 23 is adapted to the tracks provided on the inner wall of the housing 1, reducing the resistance encountered by the drawer-type tray as it moves forward and backward through the opening, thereby reducing the time required for opening and closing.

[0043] To further ensure the ambient temperature inside the tray, in a preferred embodiment, a thermal insulation layer is provided on the outer surface of the panel. In some specific embodiments, the thermal insulation layer is made of polyurethane foam, polystyrene foam, or rock wool. Of course, the material of the thermal insulation layer is not the only limitation, and other insulation materials may be used in other embodiments.

[0044] Meanwhile, in a preferred embodiment, the opening is designed to fit the size of the pallet body. This design ensures that the pallet can enter and exit while minimizing the space for instability, thereby ensuring a stable ambient temperature inside the pallet.

[0045] Furthermore, to ensure that the overall state inside the environmental enclosure remains unchanged, in a preferred embodiment, the structures of the first thermal insulation barrier 3 and the second thermal insulation barrier 4 are optimized. The first thermal insulation barrier 3 is a plate-like structure, installed around the opening on the outside of the enclosure to form an opening and closing structure; the second thermal insulation barrier 4 is a plate-like structure, installed around the opening inside the enclosure to form an opening and closing structure.

[0046] Preferably, the first thermal insulation barrier 3 is connected to the housing 4 via a hinge or snap fastener; the second thermal insulation barrier 4 is connected to the housing 1 via a hinge. Of course, the design of the opening and closing structure is not the only limitation; in other embodiments, other connection methods can be used to achieve opening and closing.

[0047] To further isolate the internal environment from external influences, the outer shell of the first thermal insulation barrier 3 or the second thermal insulation barrier 4 inside the enclosure is made of metal or engineering plastic, while the inner shell is made of polyurethane foam, polystyrene foam, or rock wool. The size of the first thermal insulation barrier 3 or the second thermal insulation barrier 4 is larger than the opening size. Of course, the materials of the outer shell and the inner shell are not the only limitations, and other materials may be used in other embodiments.

[0048] In some specific embodiments, such as Figure 2 and Figure 3 As shown, the first thermal insulation barrier 3 is a plate-shaped structure that is hinged to the outside of the box 1 below the opening, and the second thermal insulation barrier 4 is a plate-shaped structure that is hinged to the inside of the box above the opening. Figure 2 The upper part of Figures (a) and (b) shows the structure without the pallet. At this time, the first thermal insulation barrier 3 and the second thermal insulation barrier 4 both close the opening to prevent external influence on the internal environment of the box. Figure 2 The structure shown in the lower part of Figures (a) and (b) is as follows: Figure 3This is a structural diagram of the tray being loaded. At this time, the first thermal insulation barrier 3 is perpendicular to the box 1, the second thermal insulation barrier 4 is at a 30-45 degree angle to the box 1, and the tray panel seals the opening.

[0049] The above embodiments employ various insulation methods to ensure a stable ambient temperature inside the tray. However, connecting the test sample to the test harness requires being done inside the environmental chamber, inevitably consuming time spent opening the tray. Therefore, in a preferred embodiment, a connector is configured on the outside of the panel, and the connector connects to the test sample placed inside the tray body via a connecting cable. This design allows the connector to be inserted and removed outside the environmental chamber, eliminating the need for internal contact and further reducing environmental impact.

[0050] The specific implementation process of this utility model is as follows:

[0051] The test environment is established inside the chamber. Before the test sample is placed in the chamber, the opening is sealed twice by the first thermal insulation barrier 3 and the second thermal insulation barrier 4 to prevent the chamber environment from being affected by the outside. The test sample needs to be placed in the chamber by placing it in the tray 2, which is inserted into the opening. At this time, the first thermal insulation barrier 3 is perpendicular to the chamber, and the second thermal insulation barrier 4 forms a certain angle with the chamber. The tray panel has an insulating function, covering the opening and preventing the internal environment of the chamber from being affected by the outside.

[0052] The drawer features sliding rails on both sides, allowing for quick tray extraction and reducing tray opening and closing time. Additionally, connectors are located on the outside of the tray, enabling connection and disconnection with other testing equipment from outside the enclosure, further minimizing tray opening time.

[0053] The embodiments of this utility model address two aspects: reducing door opening and closing time and increasing insulation measures, so that the overall state of the rapid environmental chamber remains unchanged.

[0054] It is worth noting that: Figure 4 and Figure 5 As shown, tray 2 has a drawer-like structure, with sample 26 placed inside, its height lower than the perimeter of tray 2. During the insertion of tray 2 into the opening, the second thermal insulation barrier 4 always contacts the top of the tray body 22 of tray 2, as... Figure 3 and Figure 6 As shown. Therefore, the second thermal insulation barrier 4 will not affect the samples placed inside the tray 2.

[0055] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
