Description

Technical Field

[0001] The present application relates to the field of test equipment, and in particular to a constant temperature and humidity generator. Background Art

[0002] Constant temperature and humidity generator is also called constant temperature and humidity testing machine or constant temperature and humidity test box, etc. It is mainly used to test the performance of materials in various environments and to test the heat resistance, cold resistance, dryness resistance and moisture resistance of various materials.

[0003] In the related art, during the test of the constant temperature and humidity test machine, it is sometimes necessary to open the door to take out the test piece, or to add, reduce or replace the test piece. In the actual operation, after the door is opened, the air inside the constant temperature and humidity test machine will convect with the air outside, which causes the air outside the box to exchange with the air inside the box. The temperature and humidity of the air outside and inside the box are quite different, which leads to a large change in the temperature and humidity of the air inside the constant temperature and humidity test machine, and then causes the temperature and humidity of the air inside the constant temperature and humidity test machine to be unbalanced. The temperature and humidity of the air inside the test machine need to be readjusted. The next test piece can be put into the test machine for testing only after the test machine is adjusted to the preset temperature and humidity. This makes the entire test process of the test piece inefficient and is not conducive to the daily test of the test piece. Summary of the invention

[0004] The present application provides a constant temperature and humidity generator, the purpose of which is to effectively avoid convection between the air in the testing machine and the outside air when the test piece in the testing machine is taken out of the testing machine, thereby effectively preventing the air in the testing machine from being exchanged with the air outside the testing machine, which is beneficial to ensuring the balance of temperature and humidity of the air in the testing machine. There is no need to readjust the temperature and humidity of the air in the testing machine. After the test piece is taken out of the testing machine, the next test piece can be immediately placed in the testing machine for testing, which is beneficial to improving the daily testing efficiency of the test piece.

[0005] The present application provides a constant temperature and humidity generator, which adopts the following technical solution:

[0006] A constant temperature and humidity generator, comprising a test box, wherein a partition is fixed inside the test box, wherein the partition divides the inside of the test box into an installation chamber and a test chamber, wherein the installation chamber is used to assemble a corresponding temperature regulator and a humidity regulator, wherein the installation chamber and the test chamber are kept in communication, wherein a test box is arranged in the test chamber, wherein a movable door is slidably installed in a vertical direction on a side of the test chamber away from the installation chamber, wherein a driving assembly is arranged at the bottom of the test chamber, wherein the driving assembly is used to drive the test box to slide in a direction close to or away from the movable door;

[0007] A rotating shaft is provided in the horizontal direction on one side of the test chamber near the movable door, and the rotating shaft is used to drive the specimen box to rotate in the test chamber, and the rotating shaft drives the movable door to rise and fall;

[0008] A first sealing plate is installed at the bottom of the movable door in the vertical direction, the first sealing plate is fastened to the test box, and the first sealing plate and the movable door are used to seal the test box;

[0009] The test box is used to seal between the first sealing plate and the movable door, and one side of the test box is a hinged plate, and the hinged plate is used to take the test piece in the test box out of the test cavity.

[0010] By adopting the above technical solution, during the process of the movable door rising to open the test box, the sealing of the test box is divided into two stages.

[0011] Phase 1: The movable door rises and the test box rotates. When the bottom of the movable door has not risen to the top of the first sealing plate, the movable door and the first sealing plate are sealed, that is, there is no gap between the movable door and the first sealing plate, and the air outside the test box cannot enter the test box. In this state, the sealing of the test box is still achieved by the cooperation of the movable door and the first sealing plate.

[0012] The second stage: As the movable door continues to rise, when the bottom of the movable door rises above the top of the first sealing plate, a gap will appear between the bottom of the movable door and the top of the first sealing plate, and the outside air can penetrate into the test box through the gap. When the bottom of the movable door rises above the top of the first sealing plate, the test box rotates to a vertical state. In this state, the gap between the movable door and the first sealing plate is blocked by the test box, and the sealing inside the test box is effectively guaranteed by the test box, effectively preventing the outside air from penetrating into the test box through the gap between the movable door and the first sealing plate. That is, the sealing inside the test box in the second stage is achieved by the cooperation of the test box, the first sealing plate and the movable door.

[0013] This setting can effectively avoid convection between the air inside the testing machine and the outside air when the test piece is taken out of the testing machine, and can effectively prevent the exchange of air inside the testing machine with the air outside the testing machine, which is beneficial to ensure the balance of temperature and humidity of the air inside the testing machine. There is no need to readjust the temperature and humidity of the air inside the testing machine. After the test piece is taken out of the testing machine, the next test piece can be immediately put into the testing machine for testing, which is beneficial to improve the daily testing efficiency of the test pieces.

[0014] Preferably, the driving assembly comprises a first motor, a screw and a sliding seat, the first motor is fastened to the inner wall of the bottom of the test chamber, the screw is horizontally mounted on the driving end of the first motor, the sliding seat is sleeved on the screw and matched with the screw thread;

[0015] A linkage rod is vertically installed on the top of the sliding seat, and the bottom of the linkage rod is integrally connected to the sliding seat. The top of the linkage rod is integrally connected to a connecting seat in the horizontal direction. The connecting seat is located below the test box. A plurality of plug rods are integrally formed on the top of the connecting seat. A plurality of sockets are penetrated through the bottom of the test box. The plurality of plug rods and the plurality of sockets correspond to each other one by one, and the corresponding plug rods and the sockets are plug-fitted.

[0016] By adopting the above technical solution, the first motor is turned on, and the first motor drives the screw rod to rotate while driving the sliding seat to slide along the length direction of the screw rod. During the sliding process of the sliding seat, the linkage rod is lifted and lowered, and the linkage rod is lifted and lowered while driving the connecting seat to move toward or away from the test piece box, thereby realizing the connection and disconnection between the connecting seat and the test piece box.

[0017] When the specimen needs to be taken out of the test box, the first motor is turned on, and the sliding seat moves forward while the linkage rod rises, driving the connecting seat to rise through the linkage rod, so that the insertion rod on the connecting seat is inserted upward into the corresponding insertion hole at the bottom of the specimen box. After the connecting seat and the specimen box are connected through the insertion rod and the insertion hole, the sliding seat drives the specimen box to slide in the direction close to the rotating shaft through the connecting seat until the specimen box is rotationally connected with the rotating shaft.

[0018] Then, the sliding seat retreats, driving the linkage rod to descend. When the linkage rod descends, it also drives the connecting seat to descend, so that the insertion rod on the connecting seat extends from the insertion hole of the specimen box, thereby disconnecting the connection between the connecting seat and the specimen box, effectively preventing the connecting seat from interfering with the rotation of the specimen box during the rotation of the specimen box.

[0019] Preferably, a driving gear is installed at the end of the screw rod away from the first motor in the vertical direction, the bottom of the driving gear is meshed and connected with a driven gear in the horizontal direction, the axis of the driven gear is integrally connected with a lifting screw in the vertical direction, a lifting seat is sleeved on the lifting screw in the horizontal direction, the lifting seat is threadedly matched with the lifting screw, a first rack is integrally connected to the side of the lifting seat close to the sliding seat in the horizontal direction, a first gear is sleeved on the linkage rod in the horizontal direction, and the first gear is meshed and connected with the first rack;

[0020] The linkage rod includes a first rod body and a second rod body, the first rod body and the second rod body are both vertically arranged, the first rod body is located above the second rod body, the top of the first rod body is connected to the connecting seat, the bottom of the first rod body is sleeved in the second rod body, and the circumference of the first rod body is threadedly matched with the second rod body, the top of the sliding seat is fastened with a bearing seat in the horizontal direction, the bottom of the second rod body is rotatably installed in the bearing seat, and the first gear is integrally sleeved on the circumference of the second rod body.

[0021] By adopting the above technical solution, while the first motor drives the screw to rotate so that the sliding seat slides along the length direction of the screw, the screw synchronously drives the driving gear to rotate. During the rotation process, the driving gear meshes with the driven gear to drive the driven gear to rotate, and then drives the rotation of the lifting screw through the driven gear. As the lifting screw rotates, the lifting seat is lifted and lowered along the length direction of the lifting screw, and the lifting seat drives the first rack to lift and lower during the lifting process. During the lifting process of the first rack, the first gear meshes with the first rack, and then drives the first gear to rotate through the first rack, and drives the second rod body to rotate in the bearing seat through the first gear. Since the first rod body is threadedly sleeved in the second rod body, the second rod body drives the lifting and lowering of the first rod body while rotating, and then the lifting and lowering of the connecting seat is realized through the first rod body, and the connection and disconnection between the sliding seat and the specimen box are realized through the lifting and lowering of the connecting seat.

[0022] Preferably, two support seats are fixed in the test cavity along the horizontal direction, the two support seats are spaced apart in the test cavity, through holes are formed at the ends of the two support seats, and the two ends of the rotating shaft are respectively inserted into the through holes of the two support seats;

[0023] A second motor is connected to one end of the rotating shaft, and the second motor is used to drive the rotating shaft to rotate. A transfer plate is integrally connected to one side of the test box close to the rotating shaft in a horizontal direction, and an end of the transfer plate away from the test box is open, and a circular arc-shaped transfer groove is provided inside the transfer plate;

[0024] The left and right ends of the rotating shaft are integrally provided with second gears in the vertical direction, and the left and right sides of the movable door are installed with second racks in the vertical direction. The two second gears correspond to the two second racks one by one, and the corresponding second gears are meshed and connected with the second racks.

[0025] By adopting the above technical solution, the sliding seat slides the specimen box toward the direction close to the rotating shaft through the connecting seat. While the specimen box slides, it synchronously drives the adapter plate to slide toward the direction close to the rotating shaft until the rotating shaft is inserted into the adapter groove on the adapter plate from the opening of the adapter plate. After the rotating shaft is inserted into the adapter groove, the connecting seat descends and disconnects from the specimen box. When the second motor is turned on, the second motor drives the rotating shaft to rotate, while driving the adapter plate and the specimen box to rotate clockwise in the test chamber.

[0026] While the second motor drives the rotating shaft to rotate, it also drives the two second gears to rotate synchronously through the rotating shaft. The two second gears engage with the corresponding second racks during rotation. The two second gears drive the two second racks to rise and fall, and then the two second racks drive the movable door to rise and fall. The rotating shaft drives the specimen box to rotate while driving the movable door to rise and fall.

[0027] Preferably, both left and right sides of the movable door are provided with sliding grooves in the vertical direction, and the two second racks are slidably installed in the two sliding grooves respectively.

[0028] By adopting the above technical solution, when the second rack drives the movable door to move up and down, the slide groove guides the lifting of the second rack, which is beneficial to ensure the stability of the movable door during the lifting process.

[0029] Preferably, the specimen box comprises a first box body and a second box body which are connected in one piece, the left and right sides of the second box body are open, the second box body is used to store the specimen, and the first box body is located on a side of the second box body away from the rotation axis;

[0030] The first box body is provided with a sealing assembly, and the sealing assembly is used to seal the second box body during the rotation of the specimen box.

[0031] By adopting the above technical solution, since the left and right sides of the second box body are open, the air inside the second box body is likely to form convection during the rotation of the second box body, which will further have a certain impact on the temperature and humidity inside the second box body. In order to avoid this situation, during the rotation of the second box body, the sealing component on the first box body is used to further effectively seal the second box body, thereby reducing the impact of air flow on the temperature and humidity inside the second box body during the rotation of the second box body.

[0032] Preferably, the sealing assembly includes a second sealing plate, a third rack, a third gear, a fourth gear and a pulley, the second sealing plate, the third rack and the third gear are all mounted on the first box body, the side wall of the second sealing plate is integrally connected with the third rack, and the third rack is meshingly connected with the third gear, the fourth gear is mounted on the second box body, and the fourth gear is meshingly connected with the second gear on the same side, and the pulley is mounted between the third gear and the fourth gear.

[0033] By adopting the above technical solution, when the rotating shaft drives the second gear to rotate, the second gear meshes with the fourth gear on the same side, and the fourth gear on the same side is driven to rotate by the second gear. During the rotation process, the fourth gear drives the third gear to rotate through the pulley. While the third gear rotates, it drives the third rack to slide, and then drives the second sealing plate to slide in the direction of approaching or moving away from the second box body through the third rack. During the sliding process of the second sealing plate in the direction of approaching or moving away from the second box body, the second box body is sealed or opened.

[0034] Preferably, guide plates are installed horizontally on both upper and lower sides of the first box body, slide rails are formed between the side walls of the two guide plates and the first box body, and the upper and lower ends of the second sealing plate are respectively embedded between the two slide rails.

[0035] By adopting the above technical solution, during the sliding movement of the second sealing plate between the first box body and the second box body, the slide rail guides the sliding movement of the second sealing plate, thereby facilitating the stability of the sliding movement of the second sealing plate and, at the same time, ensuring the accuracy of the sealing of the second sealing plate to the second box body.

[0036] In summary, the present application includes at least one of the following beneficial technical effects:

[0037] 1. When the movable door rises to open the test chamber, the sealing of the test chamber is divided into two stages.

[0038] Phase 1: The movable door rises and the test box rotates. When the bottom of the movable door has not risen to the top of the first sealing plate, the movable door and the first sealing plate are sealed, that is, there is no gap between the movable door and the first sealing plate, and the air outside the test box cannot enter the test box. In this state, the sealing of the test box is still achieved by the cooperation of the movable door and the first sealing plate.

[0039] The second stage: As the movable door continues to rise, when the bottom of the movable door rises above the top of the first sealing plate, a gap will appear between the bottom of the movable door and the top of the first sealing plate, and the outside air can penetrate into the test box through the gap. When the bottom of the movable door rises above the top of the first sealing plate, the test box rotates to a vertical state. In this state, the gap between the movable door and the first sealing plate is blocked by the test box, and the sealing inside the test box is effectively guaranteed by the test box, effectively preventing the outside air from penetrating into the test box through the gap between the movable door and the first sealing plate. That is, the sealing inside the test box in the second stage is achieved by the cooperation of the test box, the first sealing plate and the movable door.

[0040] This setting can effectively prevent the air in the test machine from convection with the outside air when the test piece is taken out of the test machine, and can effectively prevent the air in the test machine from exchanging with the air outside the test machine, which is conducive to ensuring the balance of temperature and humidity of the air in the test machine. There is no need to readjust the temperature and humidity of the air in the test machine. After the test piece is taken out of the test machine, the next test piece can be immediately put into the test machine for testing, which is conducive to improving the daily test efficiency of the test piece.

[0041] 2. Since the left and right sides of the second box body are open, the air inside the second box body is likely to form convection during the rotation of the second box body, which will have a certain impact on the temperature and humidity inside the second box body. In order to avoid this situation, the second box body is further effectively sealed by the sealing component on the first box body during the rotation of the second box body, thereby reducing the impact of air flow on the temperature and humidity inside the second box body during the rotation of the second box body;

[0042] 3. When the second sealing plate slides between the first box body and the second box body, the slide rail guides the sliding of the second sealing plate, which is beneficial to ensure the stability of the sliding process of the second sealing plate and the accuracy of the sealing of the second box body by the second sealing plate.

DETAILED DESCRIPTION

[0049] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0050] Example:

[0051] The present application discloses a constant temperature and humidity generator, referring to Figure 1 and Figure 2 , including a test box 1, which is in the shape of a rectangular parallelepiped as a whole, and a partition 2 is welded inside the test box 1 along the vertical direction, and the partition 2 divides the inside of the test box 1 into an installation chamber 3 and a test chamber 4 on the left and right sides. The installation chamber 3 is used to assemble the corresponding temperature regulator and humidity regulator, and the installation chamber 3 and the test chamber 4 are kept in communication. A test piece box 5 is arranged in the test chamber 4, and the test piece box 5 is horizontally arranged, and the left and right sides of the test piece box 5 are open, and the corresponding test piece is stored in the test piece box 5. The temperature and humidity in the test chamber 4 are adjusted by the temperature regulator and humidity regulator in the installation chamber 3, so that the test piece can always be kept at the preset temperature and humidity.

[0052] At the same time, refer to Figure 2 and Figure 3, on the side of the test chamber 4 away from the installation chamber 3, a movable door 6 capable of moving up and down is provided vertically. The test chamber 4 is opened or closed through the movable door 6. At the same time, a driving assembly 7 for driving the specimen box 5 to slide in the test chamber 4 is provided at the bottom of the test chamber 4. The driving assembly 7 is used to drive the specimen box 5 to slide in a direction close to or away from the movable door 6. A rotating shaft 8 is additionally provided horizontally on the side of the test chamber 4 close to the movable door 6. The driving assembly 7 drives the specimen box 5 to slide in a direction close to the rotating shaft 8 until the specimen box 5 is rotationally connected to the rotating shaft 8. The rotating shaft 8 is used to drive the specimen box 5 to rotate in the test chamber 4. At the same time, the rotating shaft 8 drives the movable door 6 to rise and opens the test chamber 4.

[0053] Refer to Figure 2 and Figure 3 , a first sealing plate 9 is installed vertically at the bottom of the movable door 6. The first sealing plate 9 is integrally in a "U" - shaped structure. The first sealing plate 9 is fastened to the test chamber 1 through fastening bolts. The first sealing plate 9 seals the movable door 6 and effectively guarantees the airtightness inside the test chamber 1. When the bottom of the movable door 6 rises above the first sealing plate 9, a gap will appear between the bottom of the movable door 6 and the top of the first sealing plate 9 at this time.

[0054] In this state, to effectively prevent the outside air from infiltrating into the test chamber 1 through the gap between the movable door 6 and the first sealing plate 9, during the upward opening process of the movable door 6, the specimen box 5 rotates clockwise synchronously driven by the rotating shaft 8, and the specimen box 5 cooperates with the movable door 6 to seal the test chamber 1 during the rotation process. When the bottom of the movable door 6 rises above the first sealing plate 9, the gap between the movable door 6 and the first sealing plate 9 is blocked by the specimen box 5, thereby effectively guaranteeing the airtightness inside the test chamber 1 through the specimen box 5 and effectively preventing the outside air from infiltrating into the test chamber 1 through the gap between the movable door 6 and the first sealing plate 9.

[0055] Refer to Figure 2 , Figure 3 and Figure 4 , one side of the specimen box 5 is a hinge plate 10. After the specimen box 5 rotates from the horizontal state to the vertical state, the specimen box 5 and the movable door 6 seal the test chamber 1. In this state, the hinge plate 10 is located outside the test chamber 1. Open the hinge plate 10 and take out the specimen in the specimen box 5. This enables the test chamber 1 to always be in a sealed state during the process of taking out the specimen. After the next specimen is stored in the specimen box 5, the specimen box 5 rotates into the test chamber 1. At the same time, the movable door 6 descends. During this process, the specimen box 5 and the movable door 6 still seal the test chamber 1. After the movable door 6 descends below the first sealing plate 9, the first sealing plate 9 continues to seal the movable door 6.

[0056] It should be noted here that, in the initial state when the specimen box 5 is in the test chamber 4, the hinged plate 10 on the specimen box 5 is at the top of the specimen box 5. When the specimen box 5 is rotationally connected to the first rotating shaft 8 and begins to rotate 90° clockwise in the test chamber 4, the hinged plate 10 rotates to the right side of the specimen box 5.

[0057] This setting can effectively avoid convection between the air inside the testing machine and the outside air when the test piece is taken out of the testing machine, and can effectively prevent the exchange of air inside the testing machine with the air outside the testing machine, which is beneficial to ensure the balance of temperature and humidity of the air inside the testing machine. There is no need to readjust the temperature and humidity of the air inside the testing machine. After the test piece is taken out of the testing machine, the next test piece can be immediately put into the testing machine for testing, which is beneficial to improve the daily testing efficiency of the test pieces.

[0058] In summary, during the process of the movable door 6 rising to open the test box 1, the sealing of the test box 1 is divided into two stages.

[0059] The first stage: the movable door 6 rises and the specimen box 5 rotates. When the bottom of the movable door 6 has not risen to the top of the first sealing plate 9, the movable door 6 and the first sealing plate 9 are sealed, that is, there is no gap between the movable door 6 and the first sealing plate 9, and the air outside the test box 1 cannot enter the test box 1. In this state, the sealing of the test box 1 is still achieved by the cooperation of the movable door 6 and the first sealing plate 9.

[0060] The second stage: As the movable door 6 continues to rise, when the bottom of the movable door 6 rises above the top of the first sealing plate 9, a gap will appear between the bottom of the movable door 6 and the top of the first sealing plate 9, and the outside air can penetrate into the test box 1 through the gap. When the bottom of the movable door 6 rises above the top of the first sealing plate 9, the test box 5 rotates to a vertical state. In this state, the gap between the movable door 6 and the first sealing plate 9 is blocked by the test box 5, and the sealing of the inside of the test box 1 is effectively guaranteed by the test box 5, effectively preventing the outside air from penetrating into the test box 1 through the gap between the movable door 6 and the first sealing plate 9. That is, the sealing inside the test box 1 in the second stage is achieved by the cooperation of the test box 5, the first sealing plate 9 and the movable door 6.

[0061] Specifically, refer to Figure 2 , Figure 3 as well as Figure 4The driving assembly 7 includes a first motor 71, a screw 72 and a sliding seat 73. The first motor 71 is fastened to the inner wall at the bottom of the test chamber 4 by fastening bolts. The screw 72 is horizontally installed on the driving end of the first motor 71. The sliding seat 73 is sleeved on the screw 72 and threadedly matched with the screw 72. A linkage rod 11 is vertically installed on the top of the sliding seat 73. The bottom of the linkage rod 11 is integrally connected to the sliding seat 73. The top of the linkage rod 11 is integrally connected to a connecting seat 12 in the horizontal direction. The connecting seat 12 is located below the specimen box 5. A plurality of plug rods 13 are integrally formed on the top of the connecting seat 12. A plurality of circular plug holes 14 are provided through the bottom of the specimen box 5. These plug rods 13 correspond to the plug holes 14 one by one, and the corresponding plug rods 13 and the plug holes 14 are plugged and matched.

[0062] Specifically, the first motor 71 is turned on, and the first motor 71 drives the screw rod 72 to rotate while driving the sliding seat 73 to slide along the length direction of the screw rod 72. During the sliding process of the sliding seat 73, the linkage rod 11 is lifted and lowered. The linkage rod 11 drives the connecting seat 12 to move toward or away from the specimen box 5 while being lifted and lowered, thereby realizing the connection and disconnection between the connecting seat 12 and the specimen box 5.

[0063] When the specimen needs to be taken out of the test box 1, the first motor 71 is turned on, and the sliding seat 73 moves forward while the linkage rod 11 rises, and the connecting seat 12 is driven to rise through the linkage rod 11, so that the insertion rod 13 on the connecting seat 12 is inserted upward into the corresponding insertion hole 14 at the bottom of the specimen box 5. After the connecting seat 12 and the specimen box 5 are connected through the insertion rod 13 and the insertion hole 14, the sliding seat 73 drives the specimen box 5 to slide toward the direction close to the rotating shaft 8 through the connecting seat 12 until the specimen box 5 is rotationally connected with the rotating shaft 8.

[0064] Then, the sliding seat 73 retreats, driving the linkage rod 11 to descend. When the linkage rod 11 descends, the connecting seat 12 is synchronously driven to descend, so that the insertion rod 13 on the connecting seat 12 extends from the insertion hole 14 of the specimen box 5, thereby disconnecting the connection between the connecting seat 12 and the specimen box 5, effectively preventing the connecting seat 12 from interfering with the rotation of the specimen box 5 during the rotation of the specimen box 5.

[0065] Specifically, refer to Figure 2 and Figure 3The end of the screw rod 72 away from the first motor 71 is provided with a driving gear 15 in the vertical direction, the bottom of the driving gear 15 is meshed and connected with a driven gear 16 in the horizontal direction, the axis of the driven gear 16 is integrally connected with a lifting screw 17 in the vertical direction, a lifting seat 18 is sleeved on the lifting screw 17 in the horizontal direction, and the lifting seat 18 is threadedly matched with the lifting screw 17. The lifting seat 18 is integrally connected with a first rack 19 in the horizontal direction on one side close to the sliding seat 73. At the same time, a first gear 20 is sleeved on the linkage rod 11 in the horizontal direction, and the first gear 20 is meshed and connected with the first rack 19.

[0066] Reference Figure 3 and Figure 4 The linkage rod 11 includes a first rod body 111 and a second rod body 112. The first rod body 111 and the second rod body 112 are both arranged vertically, and the first rod body 111 is located above the second rod body 112. The top of the first rod body 111 is connected to the connecting seat 12, the bottom of the first rod body 111 is sleeved in the second rod body 112, and the circumference of the first rod body 111 is threadedly matched with the second rod body 112. The top of the sliding seat 73 is fastened with a bearing seat 21 in the horizontal direction, and the bottom of the second rod body 112 is rotatably installed in the bearing seat 21. The first gear 20 is sleeved on the circumference of the second rod body 112.

[0067] Specifically, while the first motor 71 drives the screw 72 to rotate so that the sliding seat 73 slides along the length direction of the screw 72, the screw 72 simultaneously drives the driving gear 15 to rotate, and the driving gear 15 meshes with the driven gear 16 during the rotation process to drive the driven gear 16 to rotate, and then drives the rotation of the lifting screw 17 through the driven gear 16. As the lifting screw 17 rotates, the lifting seat 18 is lifted and lowered along the length direction of the lifting screw 17, and the lifting seat 18 drives the first rack 19 to lift and lower during the lifting process. During the lifting and lowering process of the first rack 19, the first gear 20 meshes with the first rack 19, and then the first gear 20 is driven to rotate through the first rack 19, and the second rod body 112 is driven to rotate in the bearing seat 21 through the first gear 20. Since the first rod body 111 is threadedly sleeved in the second rod body 112, the second rod body 112 drives the lifting and lowering of the first rod body 111 while rotating, and then the lifting and lowering of the connecting seat 12 is realized through the first rod body 111, and the connection and disconnection between the sliding seat 73 and the specimen box 5 are realized through the lifting and lowering of the connecting seat 12.

[0068] Specifically, refer to Figure 2 , Figure 3 as well as Figure 4Two support seats 22 are welded in the horizontal direction in the test chamber 4, and the two support seats 22 are spaced apart in the test chamber 4. Through holes are provided at the ends of the two support seats 22, and the two ends of the rotating shaft 8 are respectively inserted into the through holes of the two support seats 22, so that the rotating shaft 8 is stably supported by the two support seats 22. A second motor 23 is connected to one end of the rotating shaft 8, and the second motor 23 is located outside the test box 1. The second motor 23 is used to drive the rotating shaft 8 to rotate. A transfer plate 24 is integrally connected to one side of the specimen box 5 close to the rotating shaft 8 in the horizontal direction, and the end of the transfer plate 24 away from the specimen box 5 is open, and a transfer groove 25 in the shape of an arc is provided inside the transfer plate 24.

[0069] Specifically, the sliding seat 73 slides the specimen box 5 toward the direction close to the rotating shaft 8 through the connecting seat 12. While the specimen box 5 slides, it synchronously drives the adapter plate 24 to slide toward the direction close to the rotating shaft 8 until the rotating shaft 8 is inserted into the adapter groove 25 on the adapter plate 24 from the opening of the adapter plate 24. After the rotating shaft 8 is inserted into the adapter groove 25, the connecting seat 12 descends and disconnects from the specimen box 5. The second motor 23 is turned on. While the second motor 23 drives the rotating shaft 8 to rotate, it drives the adapter plate 24 and the specimen box 5 to rotate clockwise in the test chamber 4.

[0070] In this embodiment, the adapter plate 24 is made of rubber material, which is relatively soft and easy to deform. When the adapter plate 24 slides to the rotating shaft 8 and the rotating shaft 8 is inserted into the adapter groove 25, the adapter plate 24 is easy to deform, which helps the rotating shaft 8 to be inserted into the adapter groove 25 more smoothly. At the same time, the rubber material makes the adapter plate 24 elastic, which is conducive to ensuring the stability of the connection between the rotating shaft 8 and the adapter plate 24 after the rotating shaft 8 is inserted into the adapter groove 25.

[0071] It should be noted here that after the adapter plate 24 slides toward the direction close to the rotating shaft 8 so that the rotating shaft 8 is inserted into the adapter groove 25, the front end of the adapter plate 24 is in contact with the first sealing plate 9. The purpose of this is that after the front end of the adapter plate 24 is in contact with the first sealing plate 9, when the adapter plate 24 is rotated to a vertical state, the test piece box 5 can be closely attached to the first sealing plate 9, thereby enabling the test piece box 5 to cover the gap between the movable door 6 and the first sealing plate 9 more tightly, further preventing the outside air from entering the test box 1.

[0072] Reference Figure 2 and Figure 3 The left and right ends of the rotating shaft 8 are integrally provided with second gears 26 in the vertical direction. At the same time, the left and right sides of the movable door 6 are installed with second racks 27 in the vertical direction. The two second gears 26 correspond to the two second racks 27 one by one, and the corresponding second gears 26 and the second racks 27 are meshed and connected.

[0073] While driving the rotating shaft 8 to rotate, the second motor 23 synchronously drives the two second gears 26 to rotate through the rotating shaft 8. The two second gears 26 engage with the corresponding second racks 27 during the rotation process. The two second gears 26 drive the two second racks 27 to rise and fall, and then the two second racks 27 drive the movable door 6 to rise and fall. Then, the rotating shaft 8 drives the specimen box 5 to rotate and drives the movable door 6 to rise and fall.

[0074] Reference Figure 3 The left and right sides of the movable door 6 are provided with long slide grooves 28 in the vertical direction, and the two second racks 27 are respectively slidably installed in the two slide grooves 28. When the second rack 27 drives the movable door 6 to rise and fall, the slide grooves 28 guide the rise and fall of the second rack 27, which is conducive to ensuring the stability of the movable door 6 during the rise and fall process.

[0075] Further, refer to Figure 2 Figure 3 as well as Figure 4 The specimen box 5 includes a first box body 51 and a second box body 52 which are connected in one piece. The left and right sides of the second box body 52 are open. The second box body 52 is used to store specimens. The first box body 51 is located on a side of the second box body 52 away from the rotating shaft 8.

[0076] Reference Figure 4 A sealing assembly 29 is provided on the first box body 51 , and the sealing assembly 29 is used to seal the second box body 52 during the rotation of the specimen box 5 , further ensuring the sealing inside the second box body 52 , and effectively avoiding the exchange convection of air inside the second box body 52 .

[0077] Since the left and right sides of the second box body 52 are open, the air inside the second box body 52 is likely to form convection during its rotation, which will in turn have a certain impact on the temperature and humidity inside the second box body 52. ​​To avoid this, during the rotation of the second box body 52, the sealing assembly 29 on the first box body 51 further effectively seals the second box body 52, thereby reducing the impact of air flow on the temperature and humidity inside the second box body 52 during its rotation.

[0078] There are two sets of sealing components 29 , which are respectively located on the left and right sides of the first box body 51 . The left and right sides of the second box body 52 are sealed by the two sealing components 29 .

[0079] Specifically, refer to Figure 3 and Figure 4The sealing assembly 29 includes a second sealing plate 291, a third rack 292, a third gear 293, a fourth gear 294 and a pulley 295. The second sealing plate 291 is in a rectangular parallelepiped shape. The second sealing plate 291, the third rack 292 and the third gear 293 are all mounted on the first box body 51. The side wall of the second sealing plate 291 is integrally connected with the third rack 292, and the third rack 292 is meshed and connected with the third gear 293. The fourth gear 294 is mounted on the second box body 52, and the fourth gear 294 is meshed and connected with the second gear 26 on the same side. The pulley 295 is mounted between the third gear 293 and the fourth gear 294.

[0080] Specifically, when the rotating shaft 8 drives the second gear 26 to rotate, the second gear 26 meshes with the fourth gear 294 on the same side, and the fourth gear 294 on the same side is driven to rotate through the second gear 26. During the rotation process, the fourth gear 294 drives the third gear 293 to rotate through the pulley 295. While the third gear 293 rotates, it drives the third rack 292 to slide, and then drives the second sealing plate 291 to slide in the direction of approaching or moving away from the second box body 52 through the third rack 292. During the sliding process of the second sealing plate 291 in the direction of approaching or moving away from the second box body 52, the second box body 52 is sealed or opened.

[0081] Further, refer to Figure 4 and Figure 5 The first box body 51 is provided with guide plates 30 installed horizontally on both upper and lower sides. The guide plates 30 are in an "L"-shaped structure as a whole. The side walls of the two guide plates 30 are formed with slide rails 31 between the first box body 51. The upper and lower ends of the second sealing plate 291 are respectively embedded between the two slide rails 31. During the sliding movement of the second sealing plate 291 between the first box body 51 and the second box body 52, the slide rails 31 guide the sliding movement of the second sealing plate 291, which is conducive to ensuring the stability of the sliding process of the second sealing plate 291. At the same time, it can also ensure the accuracy of the second sealing plate 291 sealing the second box body 52.

[0082] The implementation principle of a constant temperature and humidity generator in the embodiment of the present application is:

[0083] One side of the test box 5 is a hinged plate 10. After the test box 5 is rotated from a horizontal state to a vertical state, the test box 1 is sealed by the test box 5 and the movable door 6. In this state, the hinged plate 10 is located outside the test box 1. The hinged plate 10 is opened to take out the test piece in the test box 5. This ensures that the test box 1 is always in a sealed state during the process of taking out the test piece. After the next test piece is stored in the test box 5, the test box 5 rotates into the test box 1, and the movable door 6 descends. During this process, the test box 5 and the movable door 6 still seal the test box 1. After the movable door 6 descends to below the first sealing plate 9, the movable door 6 continues to be sealed by the first sealing plate 9.

[0084] It should be noted here that, in the initial state when the specimen box 5 is in the test chamber 4, the hinged plate 10 on the specimen box 5 is at the top of the specimen box 5. When the specimen box 5 is rotationally connected to the first rotating shaft 8 and begins to rotate 90° clockwise in the test chamber 4, the hinged plate 10 rotates to the right side of the specimen box 5.

[0085] This setting can effectively avoid convection between the air inside the testing machine and the outside air when the test piece is taken out of the testing machine, and can effectively prevent the exchange of air inside the testing machine with the air outside the testing machine, which is beneficial to ensure the balance of temperature and humidity of the air inside the testing machine. There is no need to readjust the temperature and humidity of the air inside the testing machine. After the test piece is taken out of the testing machine, the next test piece can be immediately put into the testing machine for testing, which is beneficial to improve the daily testing efficiency of the test pieces.

[0086] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
