[0040] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0041] The test chamber is generally designed in different sizes according to the size of the test sample to better test the sample. However, when it is necessary to test samples of different sizes, it is necessary to prepare two test chambers of different sizes, or prepare a test chamber suitable for large-sized samples. The former leads to increased procurement costs and occupies a large area, which is not convenient for placement; the latter is easy to cause unnecessary waste of energy when testing small-sized samples because the entire test chamber needs to meet the predetermined test conditions. In addition, in order to ensure the accuracy of the test, only one sample is tested in the same test chamber at a time, which is also a waste of test space.

[0042] To solve the above problems, this embodiment provides a test box for simulating an environment, such as Figure 1 and Figure 2 As shown, the test box includes a box body 1 and a partition mechanism 2. The box body 1 includes an opening 11 and a column 12. The top plate 13, the back plate 14 and the bottom plate 15 of the box body 1 are all convexly provided with a sealing frame 16. The column 12 is arranged at the opening 11, and the two ends of the column 12 are detachably connected to the top plate 13 and the bottom plate 15 respectively. The partition mechanism 2 is detachably arranged in the box body 1 and seals against the column 12 and the sealing frame 16. The partition mechanism 2 divides the box body 1 into two test chambers.

[0043] In the test box, the partition mechanism 2 can separate the internal space of the box body 1 into two test chambers, and the partition mechanism 2 is sealed against the sealing frame 16, so that the two test chambers can ensure that the test conditions are independent of each other and do not affect each other. When it is necessary to test large-sized samples, the partition mechanism 2 can be removed and the two test chambers can be combined into a large space to place large-sized samples. When it is necessary to test small-sized samples, the partition mechanism 2 can be installed, and the samples can be tested separately using the two test chambers at the same time, or one of the test chambers can be used to test the samples, so that the size of the test chamber matches the size of the sample, reducing the waste of test space.

[0044] The test chamber can change the volume of the test chamber according to the size of the sample, which can not only test samples of different sizes but also prevent waste of energy and space.

[0045] This embodiment is described by taking the test box including a column 12 as an example, and the test box includes two door panels, each of which can close the corresponding test chamber. In this embodiment, the two door panels are respectively rotatably connected to the two side panels of the test box, and after the two door panels are rotated inward, they can abut against the top plate 13, the bottom plate 15 and the column 12 of the test box to close the test chamber.

[0046] In other embodiments, the test box also includes a plurality of columns 12, and a partition mechanism 2 is provided at the position of each column 12, so the test box includes a plurality of test chambers, and the door panel of the test box is rotatably provided on the top plate 13 or the bottom plate 15 to be able to close the corresponding test chamber.

[0047] The test chamber also includes a temperature control system and a humidity control system, both of which can independently adjust the temperature and humidity in each test chamber to ensure that when multiple test chambers are used to test different samples at the same time, each test chamber can meet the test conditions of the corresponding samples. Since the temperature control system and the humidity control system are relatively mature technologies in this field, they will not be described here in detail, and any device that can adjust the temperature and humidity will be used.

[0048] like Figure 3 As shown, the partition mechanism 2 includes a partition door panel 21 and a first sealing member 22 arranged around the partition door panel 21, and the first sealing member 22 is located between the sealing frame 16 and the partition door panel 21 and between the column 12 and the partition door panel 21. The partition door panel 21 can press the first sealing member 22 against the sealing frame 16 and the column 12, thereby achieving a good sealing effect and preventing the exchange of temperature and humidity between the two test chambers.

[0049] like Figure 1 to Figure 4 As shown, in order to ensure the stability of the partition door panel 21 and the sealing between different test chambers, the partition mechanism 2 also includes a locking member 23. The top plate 13 and / or the bottom plate 15 are provided with a locking groove 17. The locking member 23 is rotatably arranged on the partition door panel 21. The locking member 23 rotates into the locking groove 17 and presses the partition door panel 21 toward the sealing frame 16 and the column 12. By rotating the locking member 23, the locking and unlocking of the partition door panel 21 can be completed, thereby improving the efficiency of installing and removing the partition door panel 21.

[0050] Furthermore, if Figure 4 As shown, the inner wall of the locking groove 17 away from the sealing frame 16 includes a tightening section 171 and a fixing section 172. The tightening section 171 is inclined toward the sealing frame 16 along the direction in which the locking member 23 is rotated into the locking groove 17, and the fixing section 172 is parallel to the sealing frame 16. It can be understood that as the locking member 23 is rotated into the locking groove 17, the locking member 23 will preferentially abut against the tightening section 171, and under the guidance of the tightening section 171, it will be closer to the sealing frame 16, so that the partition door panel 21 presses the first sealing member 22 against the sealing frame 16 and the column 12, thereby improving the sealing performance. When the locking member 23 rotates to the fixing section 172, since the fixing section 172 is parallel to the sealing frame 16, the locking member 23 can be in a stable state at this time, thereby ensuring the stability of the partition door panel 21.

[0051] Specifically, the locking member 23 further includes a handle 231 , and the operator can drive the locking member 23 to rotate by rotating the handle 231 , thereby improving the convenience of operation and making it easier for the operator to install and remove the partition door panel 21 .

[0052] like Figure 5 As shown, the partition door panel 21 includes an outer panel 211 and an inner panel 212. The outer panel 211 includes a panel body 2111 and a support frame 2112 arranged around the periphery of the panel body 2111. The inner panel 212 is fixedly connected to the support frame 2112. The first heat insulating material is filled between the panel body 2111 and the inner panel 212. The panel body 2111 and the support frame 2112 of the outer panel 211 enclose a containing space for filling the first heat insulating material, and the space is closed by the inner panel 212. The first heat insulating material between the panel body 2111 and the inner panel 212 can improve the heat insulating performance of the partition door panel 21, thereby blocking the heat conduction between the two test chambers.

[0053] Specifically, the first thermal insulation material is thermal insulation wool.

[0054] In order to further improve the thermal insulation performance of the partition door panel 21, the inner panel 212 is made of a second thermal insulation material, such as a fiberglass board, and preferably a fiberglass board of FR4 grade (a material specification that must be able to extinguish itself after burning), which has a lower cost, lower thermal conductivity and good flame retardancy.

[0055] Preferably, the partition door panel 21 further includes a reinforcement frame 213, which is disposed between the support frame 2112 and the plate body 2111. The reinforcement frame 213 can improve the strength of the partition door panel 21, and prevent the partition door panel 21 from deforming under long-term temperature and humidity changes and affecting the sealing of the partition mechanism 2. At the same time, since the reinforcement frame 213 is disposed between the support frame 2112 and the plate body 2111, the thickness of the partition door panel 21 will not be increased.

[0056] Furthermore, the support frame 2112 of the outer plate 211 is formed by bending the edge of the plate body 2111. The support frame 2112 is integrally formed with the plate body 2111, which can improve production efficiency and reduce costs. Specifically, before bending the plate body 2111, the reinforcement frame 213 is firstly arranged in contact with the plate body 2111, and then the edge of the plate body is bent to form the support frame 2112, and the reinforcement frame 213 can be fixed at the same time.

[0057] like Figure 3As shown, the partition mechanism 2 includes two partition door panels 21 and two first seals 22. The two partition door panels 21 are respectively located on both sides of the sealing frame 16, and the two first seals 22 are respectively located between the two partition door panels 21 and the sealing frame 16. The two partition door panels 21 are respectively sealed against the sealing frame 16 from both sides of the sealing frame 16, which can further improve the sealing performance, thereby further reducing the heat conduction between the two test chambers.

[0058] like Figure 1 and Figure 2 As shown, the top plate 13 and the bottom plate 15 are both provided with fixing grooves 18, and the two ends of the column 12 are respectively fixedly arranged in the corresponding fixing grooves 18. Fixing the ends of the column 12 in the fixing grooves 18 can prevent the column 12 from protruding from the opening 11 of the box body 1, causing the door panel to be unable to close the corresponding test chamber, and by providing the fixing grooves 18, the contact area between the column 12 and the box body 1 can also be increased, thereby improving the stability of the fixation.

[0059] Although the column 12 and the partition door plate 21 and the sealing frame 16 and the partition door plate 21 can be sealed by the first seal 22, the two test chambers can still be heat-conducted between the column 12 and the box body 1. To solve this problem, a second seal is provided between the column 12 and the fixing groove 18.

[0060] Furthermore, the side wall of the fixing groove 18 is inclined inwardly along the direction in which the column 12 enters the fixing groove 18. Since the side wall of the fixing groove 18 is inclined, after the end of the column 12 is fixed into the fixing groove 18, as the pressure between the column 12 and the fixing groove 18 increases, the gap between the column 12 and the groove wall of the fixing groove 18 is uniformly reduced, that is, while the column 12 is tightened, the second sealing member can also be uniformly squeezed, thereby improving the sealing between the column 12 and the fixing groove 18.

[0061] like Figure 6 As shown, the column 12 is a hollow structure, and a third heat insulating material is arranged in the column 12. The third heat insulating material can improve the heat insulating performance of the column 12. Specifically, the third heat insulating material is the same as the first heat insulating material, which is heat insulating cotton. The heat insulating cotton has a changeable shape and is easy to fill. The column 12 is made of a fourth heat insulating material. In this embodiment, the fourth heat insulating material is the same as the second heat insulating material, and is also a glass fiber board of FR4 grade.

[0062] It is understandable that when the test box simulates a low temperature environment for testing, the temperature of the entire box body 1 is low and it is easy to frost after a long period of testing. However, if frost forms between the column 12 and the fixing groove 18, it will make the column 12 difficult to disassemble, thereby reducing the efficiency of disassembling and installing the partition mechanism 2.

[0063] In order to solve the above problems, heating chambers 121 are provided at both ends of the column 12. The heating chambers 121 are arranged corresponding to the fixing grooves 18, and a heating component is arranged in the heating chamber 121. By heating the two ends of the column 12 with the heating component, frost and condensation can be prevented, ensuring normal use by customers, and corrosion of the box body and affecting the on-site environment after the frost melts. Specifically, the heating component includes a heating wire and an aviation plug electrically connected to the heating wire. The top plate 13 and the bottom plate 15 of the box body 1 are both provided with sockets corresponding to the aviation plug. After the column 12 is fixed to the fixing groove 18, the aviation plug can be inserted into the socket, which reduces the difficulty of operation.

[0064] Preferably, both ends of the column 12 are provided with a snap-on base, and the top plate 13 and the bottom plate 15 of the box body 1 are correspondingly provided with a snap-on ring. After the two ends of the column 12 are respectively arranged in the fixing grooves 18 of the top plate 13 and the bottom plate 15, the snap-on ring is used to tighten the snap-on base, thereby achieving the fixation of the column 12. At the same time, the force of squeezing the second sealing member can be applied to the column 12 to improve the sealing performance.

[0065] When it is necessary to install the partition mechanism 2 on the box body 1, the operation steps are as follows:

[0066] Install the two ends of the column 12 into the fixing groove 18 respectively, and tighten the corresponding snap-on base using the snap-on rings of the top plate 13 and the bottom plate 15;

[0067] Put the partition door panel 21 in place, so that the first sealing member 22 is closely attached to the sealing frame 16 and the column 12;

[0068] Rotate the locking member 23 so that the locking member 23 is rotated into the locking groove 17 and moves to abut against the fixing section 172;

[0069] Insert the aviation plugs at both ends of the column 12 into the corresponding sockets.

[0070] When it is necessary to remove the partition mechanism 2 on the box body 1 to test a larger workpiece, the operation steps are as follows:

[0071] Rotate the locking member 23 so that the locking member 23 rotates out of the locking groove 17;

[0072] Remove the partition door panel 21;

[0073] Pull out the aviation plugs at both ends of the column 12 from the corresponding sockets;

[0074] Unlock the snap-on buckle and remove both ends of the column 12 from the fixing groove 18;

[0075] Place the workpiece to be tested into box 1;

[0076] Install the two ends of the column 12 into the fixing groove 18 respectively, and tighten the corresponding snap-on base using the snap-on rings of the top plate 13 and the bottom plate 15;

[0077] Insert the aviation plugs at both ends of the column 12 into the corresponding sockets.

[0078] It is understandable that since the workpiece is large, it is impossible to avoid the pillars 12 and put it into the box 1. Therefore, after removing the partition door panel 21 to connect the two test chambers, it is also necessary to remove the pillars 12 to put the workpiece into the box 1, and then install the pillars 12 to ensure that the box 1 can be sealed when the door panel is closed.

[0079] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
