Description

Technical Field

[0001] The present invention belongs to the technical field of heat-insulating doors, and specifically relates to a heat-insulating door. Background Art

[0002] A heat-insulating door is a door used to reduce heat transfer and maintain the stability of the original indoor temperature. Their use helps to reduce energy and heat consumption, and can reduce the load on the cooling and heating systems. Heat-insulating doors usually adopt special heat-insulating materials and sealed structure designs to block heat transfer and heat loss. Heat-insulating doors are widely used in many industries. Among them, in the biological research industry, biological samples need to be cultured at low and high temperatures, and a heat-insulating door is required to block between the low-temperature chamber and the high-temperature chamber.

[0003] Currently, existing heat-insulating doors all slide up and down through walls or ceilings to reduce the opening and closing space of the heat-insulating door. However, the cavity required for the movement of the heat-insulating door will also become a path for heat transfer, resulting in heat transfer problems between the two culture chambers. Moreover, due to the existence of the guide rail, the heat-insulating door needs to also seal and insulate the guide rail. However, due to the special heat-insulating structure and material of the heat-insulating guide rail and the broken-bridge heat-insulating structure guide rail, the heat-insulating door cannot normally seal and insulate the guide rail, and a sealing structure and method matching the structure and material of the guide rail are required to seal and insulate the guide rail. After using heat insulation for a period of time, the complex and precise specific heat-insulating sealing structure is prone to damage, resulting in the problem that the heat-insulating door cannot seal and insulate the heat-insulating guide rail, and thus cannot completely insulate the two culture chambers, leading to the problem that heat will be transferred through the guide rail, affecting the effect of continuously maintaining the temperature in the two culture chambers.

[0004] Therefore, the present invention provides a heat-insulating door. Summary of the Invention

Detailed implementation manners

[0031] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0032] Embodiment 1

[0033] As Figures 1 to 7 shown, a heat-insulating door described in an embodiment of the present invention is used in a reaction chamber 1. There are two culture chambers in the reaction chamber 1. Two slide rails 3 are fixedly connected in the reaction chamber 1. Two slide tables 4 are slidably connected to the slide rails 3. A placement plate 5 is fixedly connected to one side of the two slide tables 4. A biological sample is placed on the placement plate 5. The biological sample on the placement plate 5 is transported between the two culture chambers of the reaction chamber 1 by sliding the slide tables 4 on the two slide rails 3. It includes a heat-insulating door panel 17. The heat-insulating door panel 17 is used in the middle of the reaction chamber 1. The heat-insulating door panel 17 is used to isolate the heat transfer between the two culture chambers in the reaction chamber 1. Heat-insulating plates 16 are fixedly connected to both sides of the heat-insulating door panel 17 in the reaction chamber 1. The heat-insulating door panel 17 is slidably connected to the two heat-insulating plates 16. Second motors 21 are fixedly connected to both sides of the reaction chamber 1 where the heat-insulating door panel 17 is located. Output ends of the two second motors 21 are fixedly connected with gears 22. Tooth grooves 23 are opened on both sides of the heat-insulating door panel 17. The two gears 22 are meshed with the tooth grooves 23. Lower sealing blocks 18 are slidably connected to both sides of the heat-insulating door panel 17. A telescopic cylinder 8 is fixedly connected between the two slide rails on the lower side of the reaction chamber 1. One end of the telescopic cylinder 8 is fixedly connected with a telescopic rail 10. A first spring 9 is sleeved on the telescopic cylinder 8. One end of the first spring 9 is fixedly connected with the reaction chamber 1. The other end of the first spring 9 is fixedly connected with the telescopic rail 10. The two slide rails 3 are both slidably connected to the telescopic rail 10. The telescopic rail 10 is slidably connected to the reaction chamber 1.

[0034] Specifically, when performing high and low temperature culture treatments on biological samples, two culture chambers that continuously maintain cold and hot temperatures are required. The biological samples are moved between the two culture chambers through an electric guide rail, enabling the biological samples to undergo low and high temperature treatments. Moreover, the two culture chambers need to be isolated by a heat-insulating door to reduce heat transfer between the two culture chambers and maintain the stability of the temperatures in the two culture chambers. Currently, all heat-insulating doors slide up and down through the wall or ceiling to reduce the opening and closing space of the heat-insulating door. However, the cavity required for the movement of the heat-insulating door will also become a path for heat transfer, resulting in heat transfer problems between the two culture chambers. Additionally, due to the presence of the guide rail, the heat-insulating door needs to also seal and insulate the guide rail. Since the guide rails with heat-insulating materials and the guide rails with broken-bridge heat-insulating structures have specific heat-insulating structures and materials, the heat-insulating door cannot properly seal and insulate the guide rail, and a sealing structure and method matching the structure and material of the guide rail are required to seal and insulate the guide rail. After a period of heat insulation use, the complex and precise specific heat-insulating sealing structure is prone to damage, resulting in the problem that the heat-insulating door cannot seal and insulate the heat-insulating guide rail, and thus cannot completely insulate the two culture chambers, leading to the problem of heat transfer through the guide rail and affecting the effect of continuously maintaining the temperatures in the two culture chambers;

[0035] Place the biological sample on the placement plate 5. The sliding table 4 slides on the slide rail 3 and drives the placement plate 5 to move in the two culture chambers within the reaction chamber 1. When insulating the two culture chambers of the reaction chamber 1 through the heat-insulating door panel 17, start the second motor 21 to drive the gear 22 to rotate and make the heat-insulating door panel 17 slide downward between the two heat-insulating plates 16 through the tooth groove 23. The two heat-insulating plates 16 can insulate the walls of the two culture chambers, reducing heat transfer through the cavity where the heat-insulating door panel 17 is stored. The heat-insulating door panel 17 drives the lower sealing block 18 to move downward. When the lower end of the heat-insulating door panel 17 moves inside the reaction chamber 1, the lower sealing block 18 tightly presses against the inner wall of the lower side of the reaction chamber 1. The heat transfer between the two culture chambers is blocked by the sealing pad on one side of the lower sealing block 18. At the same time, the heat-insulating door panel 17 also presses the telescopic rail 10 downward into the reaction chamber 1 and compresses the first spring 9 through the telescopic cylinder 8, disconnecting the telescopic rail 10 from the slide rail 3 and thus blocking heat transfer through the slide rail 3, solving the problem of heat transfer through the slide rail 3 and enabling the heat-insulating door panel 17 to better insulate the two culture chambers within the reaction chamber 1.

[0036] As Figure 3 shown, a first motor 6 is fixedly connected inside each of the two sliding tables 4, and the output ends of the two first motors 6 are fixedly connected with rollers 7. The two rollers 7 are both abutted against the surface of the slide rail 3.

[0037] Specifically, since the slide rail 3 is blocked and the slide table 4 cannot be driven by the slide rail 3, the first motor 6 is started to drive the roller 7 to rotate. The friction between the roller 7 and the surface of the slide rail 3 enables the slide table 4 to move on the slide rail 3 with the placement plate 5.

[0038] As Figure 4 shown, fixed rods 11 are fixedly connected to both sides of the telescopic rail 10. Clamping blocks 13 are slidably connected to both sides of the telescopic rail 10. The two fixed rods 11 are both slidably connected to the clamping blocks 13. Second springs 12 are sleeved on the two fixed rods 11. One end of each of the two second springs 12 is fixedly connected to the telescopic rail 10, and the other end of each of the two second springs 12 is fixedly connected to the clamping block 13. Card slots matching the clamping blocks 13 are provided on one side of each of the two slide rails 3. The two clamping blocks 13 can slide into the slide rails 3. Shaped blocks 14 are fixedly connected to one side of each of the two clamping blocks 13. Two pushing blocks 15 are fixedly connected to the lower side of the heat-insulating door panel 17. The two pushing blocks 15 can both press against the shaped blocks 14 and slide with the shaped blocks 14.

[0039] Specifically, when the slide table 4 moves on the slide rail 3, the clamping blocks 13 are clamped into the slide rails 3 as Figure 4 shown, enabling the slide table 4 to move normally through the slide rail 3 and the telescopic rail 10. When the heat-insulating door panel 17 descends to press against the telescopic rail 10 for heat insulation, since the shaped block 14 is an arc-shaped block, the heat-insulating door panel 17 drives the pushing block 15 to move downward, causing the pushing block 15 to press against the shaped block 14, and the shaped block 14 drives the clamping block 13 to move. The clamping block 13 slides in the telescopic rail 10 and compresses the second spring 12 through the fixed rod 11, causing the clamping block 13 to move out of the slide rail 3. At this time, the heat-insulating door panel 17 can press against the telescopic rail 10 and move downward.

[0040] As Figure 7 shown, two side sealing blocks 19 are slidably connected to both sides of the heat-insulating door panel 17. A plurality of partition plates 24 are fixedly connected to one side of each of the plurality of side sealing blocks 19. A plurality of fixed columns 25 are fixedly connected to both sides inside the heat-insulating door panel 17. The plurality of partition plates 24 are all slidably connected to the fixed columns 25. Third springs 26 are sleeved on the plurality of fixed columns 25. One end of each of the plurality of third springs 26 is fixedly connected to the partition plate 24, and the other end of each of the plurality of third springs 26 is fixedly connected to the heat-insulating door panel 17.

[0041] Specifically, when heat insulation is carried out through the heat-insulating door panel 17, the heat-insulating door panel 17 drives the side sealing blocks 19 to move downward. The fixed columns 25 are in a compressed state and push the partition plates 24 through the third springs 26, causing the partition plates 24 to drive the side sealing blocks 19 to keep a certain distance from the reaction chamber 1, so that the sealing gasket will not rub against the reaction chamber 1 when the side sealing blocks 19 descend, reducing the situation that the sealing gasket is damaged or falls off due to the long-term friction between the side sealing blocks 19 and the reaction chamber 1.

[0042] As Figure 7As shown in the figure, sliding rods 28 are fixedly connected to both sides of the reaction chamber 1 on one side of the heat-insulating door panel 17. Connecting blocks 30 are slidably connected to both sides of the reaction chamber 1. Both sliding rods 28 are slidably connected to the connecting blocks 30. A fourth spring 29 is sleeved on one side of each of the two sliding rods 28. One end of each of the two fourth springs 29 is fixedly connected to the connecting block 30, and the other end of each of the two fourth springs 29 is fixedly connected to the reaction chamber 1. A slider 27 is fixedly connected to one side of each of the two connecting blocks 30. The heat-insulating door panel 17 can press against the sliders 27 on both sides to slide and press against the side sealing blocks 19 on both sides. A button 31 is fixedly connected to one side of each of the two connecting blocks 30.

[0043] Specifically, when heat insulation is carried out through the heat-insulating door panel 17, the slider 27 is an arc-shaped block, and the side subjected to pressing is set to be arc-shaped. The heat-insulating door panel 17 moves downward to press against the slider 27, driving the connecting block 30 to move through the sliding rod 28 and stretching the fourth spring 29, so that the slider 27 presses against the side sealing blocks 19 on both sides, enabling the side sealing blocks 19 on both sides to closely fit on the inner wall of the reaction chamber 1. When the connecting block 30 drives the button 31 to move and trigger the button 31, the second motor 21 is stopped. At this time, the heat-insulating door panel 17 completes the heat insulation function for the reaction chamber 1.

[0044] As Figure 7 shown in the figure, two telescopic sealing blocks 20 are slidably connected to both sides of the heat-insulating door panel 17. Both telescopic sealing blocks 20 are slidably connected to the lower sealing block 18. One end of each of the two telescopic sealing blocks 20 is fixedly connected to one side sealing block 19, and one end of each of the two lower sealing blocks 18 is fixedly connected to the other side sealing block 19.

[0045] Specifically, when heat insulation is carried out through the heat-insulating door panel 17, the side sealing blocks 19 on both sides move to drive the telescopic sealing blocks 20 and the lower sealing blocks 18 to move respectively, so as to better insulate the reaction chamber 1.

[0046] Embodiment 2

[0047] As Figures 8 to 10 shown in the figure, compared with Embodiment 1, another implementation manner of the present invention is as follows:

[0048] Sliding frames 32 are slidably connected to both sides of the reaction chamber 1 inside the heat-insulating door panel 17. A third motor 33 is fixedly connected to each of the two sliding frames 32. The output ends of the two third motors 33 are fixedly connected with cleaning rollers 34. One end of each of the two cleaning rollers 34 is rotatably connected to the sliding frame 32. Both cleaning rollers 34 press against the surface of the heat-insulating door panel 17.

[0049] Specifically, when the heat-insulating door panel 17 moves upward so that the biological sample on the placement plate 5 can be transported to another culture chamber, the third motor 33 is started to drive the third motor 33 to rotate, and the surface of the heat-insulating door panel 17 is cleaned through the cleaning layer on the surface of the third motor 33, preventing the liquid or dust generated during the culture of the biological sample from adhering to the surface of the heat-insulating door panel 17. After the heat-insulating door panel 17 is used for a long time, a large amount of residual liquid and dust will affect the movement of the heat-insulating door panel 17, and even damage the heat-insulating door panel 17, making the heat-insulating effect of the heat-insulating door panel 17 worse.

[0050] As Figure 10 shown, cleaning plates 37 are fixedly connected inside both sliding frames 32, and both cleaning plates 37 are abutted against one side of the cleaning roller 34.

[0051] Specifically, when cleaning the surface of the heat-insulating door panel 17, the cleaning plates 37 can scrape off the powder and the like cleaned on the cleaning roller 34 and fall into the sliding frame 32, so that the surface of the cleaning roller 34 can be kept clean and can continuously clean the surface of the heat-insulating door panel 17.

[0052] As Figure 8 shown, upper sealing blocks 39 are fixedly connected to the upper parts on both sides of the heat-insulating door panel 17, and scraping blocks 36 are fixedly connected to one side of both sliding frames 32.

[0053] Specifically, when cleaning the surface of the heat-insulating door panel 17, the scraping blocks 36 can scrape off the particles that are not cleaned cleanly by the cleaning roller 34 and adhered to the heat-insulating door panel 17. At the same time, the upper sealing blocks 39 can close the cavity passed by the heat-insulating door panel 17 as the heat-insulating door panel 17 moves, enabling the heat-insulating door panel 17 to better insulate heat. Since the scraping blocks 36 are arc-shaped blocks, when the upper sealing blocks 39 move downward, they will press against the scraping blocks 36, causing the scraping blocks 36 to drive the sliding frames 32 and the cleaning rollers 34 to move together, so that the upper sealing blocks 39 can closely adhere to the inner wall of the cavity where the heat-insulating door panel 17 moves in the reaction chamber 1.

[0054] As Figure 10 shown, sliding columns 35 are fixedly connected to one side of the reaction chamber 1 on both sides where the two sliding frames 32 are located. A fifth spring 38 is sleeved on one side of each of the plurality of sliding columns 35. The plurality of sliding columns 35 are all slidably connected to the corresponding sliding frames 32. One ends of the plurality of fifth springs 38 are fixedly connected to the reaction chamber 1, and the other ends of the plurality of fifth springs 38 are fixedly connected to the corresponding sliding frames 32.

[0055] Specifically, when the upper sealing block 39 presses against the scraping block 36 to move the sliding frame 32, the sliding frame 32 slides within the reaction chamber 1, causing the fifth spring 38 to be compressed through the sliding column 35. When the heat insulation door panel 17 drives the upper sealing block 39 to move upward, the elastic force generated when the fifth spring 38 returns to its initial state will cause the sliding frame 32 to move, enabling the cleaning roller 34 and the scraping block 36 to press against the surface of the heat insulation door panel 17 again to clean and scrape the surface of the heat insulation door panel 17.

[0056] Working principle: Place the biological sample on the placement plate 5. The sliding table 4 slides on the slide rail 3, driving the placement plate 5 to move within the two culture chambers in the reaction chamber 1. When heat insulation is provided for the two culture chambers in the reaction chamber 1 through the heat insulation door panel 17, start the second motor 21 to drive the gear 22 to rotate and cause the heat insulation door panel 17 to slide downward between the two heat insulation plates 16 through the tooth grooves 23. The two heat insulation plates 16 can insulate the walls of the two culture chambers, reducing heat transfer through the cavity where the heat insulation door panel 17 is stored. The heat insulation door panel 17 drives the lower sealing block 18 to move downward. When the lower end of the heat insulation door panel 17 moves into the reaction chamber 1, the lower sealing block 18 tightly presses against the inner wall on the lower side of the reaction chamber 1. The heat transfer between the two culture chambers is blocked by the sealing gasket on one side of the lower sealing block 18. At the same time, the heat insulation door panel 17 will also press against the telescopic rail 10 to move downward into the reaction chamber 1 and compress the first spring 9 through the telescopic cylinder 8, disconnecting the telescopic rail 10 from the slide rail 3 and thus blocking heat transfer through the slide rail 3.

[0057] Since the slide rail 3 is blocked and the slide table 4 cannot be driven by the slide rail 3, the first motor 6 is started to drive the roller 7 to rotate. The friction between the roller 7 and the surface of the slide rail 3 enables the slide table 4 to move the placement plate 5 on the slide rail 3; when the slide table 4 moves on the slide rail 3, the latch 13 is snapped into the slide rail 3 as shown in the figure, enabling the slide table 4 to move normally through the slide rail 3 and the telescopic rail 10. When the heat-insulating door panel 17 descends to press against the telescopic rail 10 for heat insulation, since the special-shaped block 14 is an arc-shaped block, the heat-insulating door panel 17 drives the pushing block 15 to move downward, causing the pushing block 15 to press against the special-shaped block 14, which in turn causes the special-shaped block 14 to drive the latch 13 to move. The latch 13 slides within the telescopic rail 10 and compresses the second spring 12 through the fixed rod 11, causing the latch 13 to move out of the slide rail 3. At this time, the heat-insulating door panel 17 can press against the telescopic rail 10 and move downward; when heat insulation is carried out through the heat-insulating door panel 17, the heat-insulating door panel 17 drives the side sealing block 19 to move downward. The fixed column 25 is in a compressed state, and the partition plate 24 is pushed by the third spring 26, causing the partition plate 24 to drive the side sealing block 19 to maintain a certain distance from the reaction chamber 1, so that the sealing gasket will not rub against the reaction chamber 1 when the side sealing block 19 descends, reducing the situation where the sealing gasket is damaged or falls off due to long-term friction between the side sealing block 19 and the reaction chamber 1; the slider 27 is an arc-shaped block, and the side subjected to pressure is set to be arc-shaped. The heat-insulating door panel 17 moves downward to press against the slider 27, driving the connecting block 30 to move through the sliding rod 28 and stretching the fourth spring 29, causing the slider 27 to press against the side sealing blocks 19 on both sides, enabling the side sealing blocks 19 on both sides to closely fit against the inner wall of the reaction chamber 1. When the connecting block 30 drives the button 31 to move and trigger the button 31, the second motor 21 is stopped. At this time, the heat-insulating door panel 17 completes the heat insulation function for the reaction chamber 1. The side sealing blocks 19 on both sides move respectively to drive the telescopic sealing block 20 and the lower sealing block 18 to move, thus better insulating the reaction chamber 1.

[0058] When the heat-insulating door panel 17 moves upward so that the biological sample on the placement plate 5 can be transported to another culture chamber, the third motor 33 is started to drive the third motor 33 to rotate, and the surface of the heat-insulating door panel 17 is cleaned through the cleaning layer on the surface of the third motor 33; the cleaning plate 37 can scrape the powder and the like cleaned on the cleaning roller 34 and fall into the sliding frame 32, so that the surface of the cleaning roller 34 can be kept clean and can continuously clean the surface of the heat-insulating door panel 17; the scraping block 36 can scrape the particles that are not cleaned cleanly by the cleaning roller 34 and adhered to the heat-insulating door panel 17. At the same time, the upper sealing block 39 moves with the heat-insulating door panel 17 to seal the cavity passed by the heat-insulating door panel 17, so that the heat-insulating door panel 17 can better insulate heat. Since the scraping block 36 is an arc-shaped block, when the upper sealing block 39 moves downward, it will press against the scraping block 36, causing the scraping block 36 to drive the sliding frame 32 and the cleaning roller 34 to move together, so that the upper sealing block 39 can closely adhere to the inner wall of the cavity where the heat-insulating door panel 17 moves in the reaction chamber 1; when the upper sealing block 39 presses against the scraping block 36 to make the sliding frame 32 move, the sliding frame 32 slides in the reaction chamber 1, and the fifth spring 38 is compressed through the sliding column 35. When the heat-insulating door panel 17 drives the upper sealing block 39 to move upward, the elastic force generated when the fifth spring 38 returns to its initial state will make the sliding frame 32 move, so that the cleaning roller 34 and the scraping block 36 press against the surface of the heat-insulating door panel 17 again to clean and scrape the surface of the heat-insulating door panel 17.
