Description

Technical Field

[0001] This invention relates to the field of constant temperature preservation devices, specifically a constant temperature preservation device for experimental analysis. Background Technology

[0002] In experimental analysis, it is usually necessary to store the solution to be analyzed in test tubes. At the same time, since the solution to be analyzed is easily oxidized by air, decomposed by sunlight, or deteriorated by temperature changes, the test tubes need to be kept in a constant temperature device to avoid errors caused by the external environment to the experimental analysis results.

[0003] However, existing constant temperature preservation devices for experimental analysis are not convenient for clamping and limiting test tubes during use, making them prone to shaking or even tipping over, which affects the preservation effect. In addition, constant temperature preservation devices are equipped with cabinet doors, which need to be opened when taking out and placing test tubes. At this time, the internal air can easily come into contact with the external air, affecting the constant temperature preservation effect. Furthermore, the relatively narrow interior of the preservation device makes it inconvenient to take out and put in test tubes. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) This kind of constant temperature preservation device for experimental analysis, by setting up a driving mechanism and a moving mechanism, when it is necessary to take out the test tube, the first motor is started. The rotation of the first motor drives the rotation of the first rotating rod and the conveying roller, which in turn drives the conveyor belt and the test tube to be conveyed, thereby conveying the test tube to be taken to the material outlet. Then, the second motor is started. The rotation of the second motor drives the rotation of the threaded rod, which in turn drives the rotation of the threaded rod, thereby pushing the sealing plate and the test tube to move, thereby extending the test tube from the material outlet. Then, the test tube can be taken out. Similarly, the test tube can be placed, which makes it easier to take out and place the test tube, and makes it more convenient and faster to use.

[0018] (2) This type of constant temperature preservation device for experimental analysis, by setting a pushing mechanism and a resetting mechanism, when the test tube is taken out, the sealing plate and the test tube move towards the material inlet. When the rounded corner abuts against the side wall of the cover plate, the cover plate is pushed to rotate outward along the rotating shaft to open. At the same time, when the rotating shaft rotates, it drives the gear to rotate, which in turn drives the rack to slide along the side wall of the guide rod. At the same time, the first spring is compressed. When the test tube extends out of the material inlet, the sealing plate can seal the material inlet, thereby reducing the contact between the air in the constant temperature chamber and the outside air, making the constant temperature preservation effect better. After the test tube is taken out, when the test tube is moved into the constant temperature chamber by the moving mechanism, under the action of the first spring, the gear and the rotating shaft can be driven to rotate and reset, thereby making the cover plate automatically rotate and reset, and sealing the material inlet, thereby reducing the contact between the air in the constant temperature chamber and the outside air, making the constant temperature preservation effect better.

[0019] (3) This type of constant temperature preservation device for experimental analysis, by setting a clamping mechanism, when placing the test tube, push the two actuating plates away from each other by hand, and drive the two arc plates away from each other. At the same time, the second spring is compressed. Then, insert the test tube between the two arc plates, and then release the actuating plates. At this time, under the action of the second spring, the two arc plates clamp and limit the test tube, making the placement of the test tube more stable and reliable, and ensuring its preservation effect.

[0020] (4) This kind of constant temperature preservation device for experimental analysis, by setting up a blower mechanism, etc., when the first rotating rod rotates, it drives the active belt pulley to rotate, thereby driving the driven belt pulley to rotate, and then driving the second rotating rod and the fan to rotate, thereby blowing air into the constant temperature chamber, which can improve the internal air flow and thus make the constant temperature preservation effect better.

[0031] Please see Figures 1-8The present invention provides a technical solution: a constant temperature preservation device for experimental analysis, including a constant temperature chamber 1, and a transparent plate 11 is provided on the side wall of the constant temperature chamber 1. A material inlet 12 is opened on the side wall of the transparent plate 11, and a cover plate 13 is rotatably connected to the side wall of the transparent plate 11 through a rotating mechanism 2. The rotation of the cover plate 13 is pushed by a pushing mechanism 8. A conveyor belt 14 is connected to the constant temperature chamber 1 through a conveying mechanism 4.

[0032] Each storage mechanism includes a U-shaped plate 15 fixedly connected to the side wall of the conveyor belt 14, and a sealing plate 16 is connected to the side wall of the U-shaped plate 15 through a moving mechanism 5. The side wall of the sealing plate 16 is provided with a clamping mechanism 6 for clamping and limiting the test tube 17, which facilitates the picking and placing of the test tube 17, makes the placement of the test tube 17 more stable and reliable, and reduces the contact between the air inside the constant temperature chamber 1 and the outside air, resulting in better constant temperature preservation.

[0033] The rotating mechanism 2 includes two symmetrically arranged fixing blocks 201 fixedly connected to the side wall of the transparent plate 11, and a rotating block 203 is rotatably connected to the side wall of the fixing block 201 via a rotating shaft 202. The rotating block 203 is fixed to the side wall of the cover plate 13, and a reset mechanism 3 for resetting the rotating shaft 202 is provided on the side wall of the fixing block 201 to ensure the normal rotation of the cover plate 13 to open or close.

[0034] The reset mechanism 3 includes a gear 301 fixedly sleeved on the side wall of the rotating shaft 202, and two symmetrically arranged support blocks 302 fixedly connected to the top of the fixed block 201. Two symmetrically arranged guide rods 303 are fixedly connected to the side wall of the support block 302, and a rack 304 is sleeved on the side wall of the guide rod 303. The rack 304 meshes with the gear 301, and a first spring 305 is sleeved on the side wall of the guide rod 303. When the rotating shaft 202 rotates, it drives the gear 301 to rotate, which in turn drives the rack 304 to slide along the side wall of the guide rod 303. At the same time, the first spring 305 is compressed, which can reset the rotating shaft 202.

[0035] The conveying mechanism 4 includes two symmetrically arranged first rotating rods 401 rotatably connected to the bottom of the constant temperature chamber 1, and the upper end of the first rotating rods 401 is rotatably connected to the top of the constant temperature chamber 1. Two symmetrically arranged conveying rollers 404 are fixedly sleeved on the side wall of the first rotating rods 401, and a support ring 402 is fixedly sleeved on the side wall of each conveying roller 404. The conveyor belt 14 is sleeved on the side wall of the conveying rollers 404, and a first motor 403 is fixedly connected to the top of the constant temperature chamber 1. When the first motor 403 is started, the rotation of the first motor 403 drives the conveyor belt 14.

[0036] The moving mechanism 5 includes a sleeve 501 fixedly connected to the side wall of the U-shaped plate 15, and a sleeve 502 is sleeved on the side wall of the sleeve 501. The other end of the sleeve 502 is fixed to the side wall of the sealing plate 16. A threaded rod 504 is rotatably connected to the side wall of the U-shaped plate 15. A threaded tube 503 is threadedly connected to the side wall of the threaded rod 504, and the other end of the threaded tube 503 is fixed to the side wall of the sealing plate 16. A second motor 505 is fixedly connected to the side wall of the U-shaped plate 15, and the output end of the second motor 505 is fixed to one end of the threaded rod 504. When the second motor 505 is started, the rotation of the second motor 505 drives the rotation of the threaded rod 504, thereby driving the sealing plate 16 and the test tube 17 to move.

[0037] The clamping mechanism 6 includes two symmetrically arranged arc-shaped plates 601, and the arc-shaped plates 601 are connected to the side wall of the sealing plate 16 through the reset assembly 7. Two symmetrically arranged actuating plates 602 are fixedly connected to the side wall of the arc-shaped plates 601. When placing the test tube 17, the two actuating plates 602 are pushed away from each other by hand, which in turn moves the two arc-shaped plates 601 away from each other. Then, the test tube 17 is inserted between the two arc-shaped plates 601, and then the actuating plates 602 are released. At this time, under the action of the reset assembly 7, the two arc-shaped plates 601 clamp and limit the test tube 17, making the placement of the test tube 17 more stable and reliable, and ensuring its preservation effect.

[0038] The reset assembly 7 includes two symmetrically arranged connecting plates 701 fixedly connected to the side wall of the sealing plate 16, and two symmetrically arranged fixing tubes 702 fixedly connected to the side wall of each connecting plate 701. A moving rod 703 is inserted into the fixing tube 702, and the other end of the moving rod 703 is fixed to the side wall of the arc plate 601. A second spring 704 is sleeved on the side wall of the fixing tube 702, which guides and resets the movement of the arc plate 601.

[0039] The pushing mechanism 8 includes a pushing rod 801 fixedly connected to the side wall of the connecting plate 701, and the end of the pushing rod 801 is provided with a rounded corner 802. When the rounded corner 802 abuts against the side wall of the cover plate 13, it pushes the cover plate 13 to rotate outward along the rotating shaft 202 to open.

[0040] The blower mechanism 9 includes a second rotating rod 901 rotatably connected to the bottom of the constant temperature chamber 1. A fan 902 is fixedly connected to the upper end of the second rotating rod 901. The rotation of the second rotating rod 901 is driven by the drive mechanism 10. When the first rotating rod 401 rotates, the drive mechanism 10 drives the second rotating rod 901 and the fan 902 to rotate, thereby blowing air into the constant temperature chamber 1, which can improve the internal air flow and thus make the constant temperature preservation effect better.

[0041] The drive mechanism 10 includes a drive pulley 1001 fixedly sleeved on the side wall of the first rotating rod 401, and a driven pulley 1002 fixedly sleeved on the side wall of the second rotating rod 901. The driven pulley 1002 and the drive pulley 1001 are driven by a belt 1003. When the first rotating rod 401 rotates, it drives the drive pulley 1001 to rotate, thereby driving the driven pulley 1002 to rotate through the belt 1003, and then driving the second rotating rod 901 and the fan 902 to rotate.

[0042] Working principle: When it is necessary to pick up the test tube 17, the first motor 403 is started. The rotation of the first motor 403 drives the rotation of the first rotating rod 401 and the conveying roller 404, which in turn drives the conveyor belt 14 and the test tube 17 to be conveyed, thereby transporting the test tube 17 to be picked up to the material inlet 12.

[0043] Next, the second motor 505 is started. The rotation of the second motor 505 drives the rotation of the threaded rod 504, which in turn drives the threaded rod 504 to rotate, thereby pushing the sealing plate 16 and the test tube 17 to move closer to the feeding port 12. When the rounded corner 802 abuts against the side wall of the cover plate 13, it pushes the cover plate 13 to rotate outward along the rotating shaft 202 to open. At the same time, when the rotating shaft 202 rotates, it drives the gear 301 to rotate, which in turn drives the rack 304 to slide along the side wall of the guide rod 303. Meanwhile, the first spring 305 is compressed.

[0044] When the test tube 17 extends from the dispensing port 12, the sealing plate 16 can seal the dispensing port 12, thereby reducing the contact between the air inside the constant temperature chamber 1 and the outside air, resulting in better constant temperature preservation. Furthermore, after the test tube 17 is removed, when the moving mechanism 5 moves the test tube 17 into the constant temperature chamber 1, the first spring 305 can drive the gear 301 and the rotating shaft 202 to rotate and reset, thereby causing the cover plate 13 to automatically rotate and reset, and seal the dispensing port 12, thereby reducing the contact between the air inside the constant temperature chamber 1 and the outside air, resulting in better constant temperature preservation.

[0045] At the same time, when the first rotating rod 401 rotates, it drives the driving pulley 1001 to rotate, which in turn drives the driven pulley 1002 to rotate via the belt 1003, which in turn drives the second rotating rod 901 and the fan 902 to rotate, thereby blowing air into the constant temperature chamber 1, which can improve the internal air flow and thus make the constant temperature preservation effect better.

[0046] Furthermore, when it is necessary to place the test tube 17, the arc-shaped plate 601 extends out from the dispensing port 12. Then, the two actuating plates 602 are pushed away from each other by hand, which in turn moves the two arc-shaped plates 601 away from each other. At the same time, the second spring 704 is compressed. Then, the test tube 17 is inserted between the two arc-shaped plates 601. Then, the actuating plates 602 are released. At this time, under the action of the second spring 704, the two arc-shaped plates 601 clamp and limit the test tube 17, making the placement of the test tube 17 more stable and reliable, and ensuring its preservation effect.
