Description

Technical Field

[0001] This utility model relates to the field of constant temperature testing equipment technology, specifically a constant temperature testing device. Background Technology

[0002] Isothermal testing is an experimental method that evaluates the performance stability and reliability of materials, products, or equipment by testing them under specific temperature conditions.

[0003] Publication number "CN208959925U" discloses a constant temperature and low temperature testing device, belonging to the field of experimental equipment technology. It addresses a technical problem where, during actual use, small reagents placed in the placement tank are prone to tilting, affecting the test results. The key technical solution includes a body with a placement tank. A storage rack is installed in the placement tank, and the rack includes a frame with several storage trays rotatably connected to it. These trays are stacked within the rack, with their axes collinear. A lifting component is provided between the frame and the inner wall of the placement tank. Several partitions are connected to the storage trays, forming storage compartments between adjacent partitions, thus reducing the tilting phenomenon of reagents placed in the placement tank.

[0004] The aforementioned patent can reduce the tilting phenomenon of reagents placed in the placement tank. However, the storage tray in the aforementioned patent cannot be disassembled. When reagents with different isothermal times are placed in the storage tray, the staff can only remove the entire storage tray. This causes reagents that require a long isothermal time to be affected by the external temperature, which can easily cause errors in subsequent tests. Utility Model Content

[0005] In order to solve the problem that the storage tray cannot be disassembled, the purpose of this utility model is to provide a constant temperature testing device.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a constant temperature testing device, including a box, a constant temperature tank is provided on the top of the box, a bearing mechanism is provided inside the constant temperature tank for placing reagents, and a constant temperature mechanism for controlling the temperature inside the constant temperature tank is provided on the top of the box.

Connecting plates are fixedly installed on both sides of the top of the base plate, the first fixed frame and the second fixed frame. A slot is opened on the top of the connecting plate. Limiting grooves are opened on both sides of the top cover, the first fixed frame and the second fixed frame. The top of the connecting plate is located in the limiting groove. Symmetrically distributed connecting blocks are fixedly installed on both sides of the top cover, the first fixed frame and the second fixed frame. Limiting rods are fixedly installed inside the connecting blocks. A locking plate is movably provided on the outside of the limiting rods. Evenly distributed load-bearing plates are fixedly installed on the inner walls of the base plate, the top cover, the first fixed frame and the second fixed frame.

[0008] Preferably, the temperature control mechanism includes a semiconductor cooling chip fixedly installed at the bottom of the temperature control bath. The bottom of the semiconductor cooling chip is provided with a pipe, which is fixedly installed through the box body. A cooling box is fixedly installed at the top of the box body. A water pump is fixedly installed inside the cooling box. The two ends of the pipe are fixedly connected to the two output ends of the water pump, respectively. A heat dissipation plate with uniform distribution is fixedly installed inside the cooling box. The pipe passes through the heat dissipation plate. A temperature sensor is provided inside the temperature control bath. The temperature sensor is electrically connected to an external controller.

[0009] Preferably, a first connecting rod and a first locking rod are fixedly installed at the four corners of the opposite sides of the bottom plate and the top cover, and a second connecting rod and a second locking rod are fixedly installed at the four corners of the top and bottom ends of the first fixing frame and the second fixing frame, respectively. Multiple first locking rods and second locking rods are movably locked in the corresponding first connecting rods and second connecting rods.

[0010] Preferably, each of the multiple bearing plates has a uniformly distributed support groove at its top, and each of the multiple bearing plates has a uniformly distributed bracket fixedly installed at its top.

[0011] Preferably, symmetrically distributed fans are fixedly installed on the top of the cooling box.

[0012] Preferably, the cooling box and the outer side of the box body are respectively provided with a first heat dissipation hole and a second heat dissipation hole that are evenly distributed.

The structure is simple and convenient for staff to operate.

[0015] 2. This application, through the setting of a first connecting rod, a first locking rod, a second connecting rod, and a second locking rod, makes the connection between the base plate, the top cover, the first fixed frame, and the second fixed frame more stable and reduces shaking.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, this utility model discloses a constant temperature testing device and provides the following two embodiments:

[0025] Example 1: A constant temperature testing device includes a housing 101, a constant temperature bath 102 is provided on the top of the housing 101, a support mechanism 1 is provided inside the constant temperature bath 102 for placing reagents, and a constant temperature mechanism 2 is provided at the top of the housing 101 for controlling the temperature inside the constant temperature bath 102.

[0026] The supporting mechanism 1 includes a base plate 11 and a top cover 12. A first fixing frame 13 and a second fixing frame 14 are provided on opposite sides of the base plate 11 and the top cover 12. Connecting plates 15 are fixedly installed on both sides of the top of the base plate 11, the first fixing frame 13 and the second fixing frame 14. A slot 16 is provided on the top of the connecting plate 15. Limiting grooves 17 are provided on both sides of the top cover 12, the first fixing frame 13 and the second fixing frame 14. The top of the connecting plate 15 is located in the limiting groove 17. Symmetrically distributed connecting blocks 18 are fixedly installed on both sides of the top cover 12, the first fixing frame 13 and the second fixing frame 14. A limiting rod 19 is fixedly installed inside the connecting block 18. A locking plate 191 is movably provided on the outside of the limiting rod 19. Evenly distributed supporting plates 192 are fixedly installed on the inner walls of the base plate 11, the top cover 12, the first fixing frame 13 and the second fixing frame 14.

[0027] Example 2 differs from Example 1 in that: the constant temperature mechanism 2 includes a semiconductor cooling chip 21 fixedly installed at the bottom of the constant temperature bath 102, a pipe 22 is provided at the bottom of the semiconductor cooling chip 21, the pipe 22 is fixedly installed through the box body 101, a cooling box 23 is fixedly installed at the top of the box body 101, a water pump 24 is fixedly installed inside the cooling box 23, the two ends of the pipe 22 are fixedly connected to the two output ends of the water pump 24 respectively, a uniformly distributed heat dissipation plate 25 is fixedly installed inside the cooling box 23, the pipe 22 passes through the heat dissipation plate 25, a temperature sensor 26 is provided inside the constant temperature bath 102, and the temperature sensor 26 is electrically connected to an external controller.

[0028] A first connecting rod 31 and a first locking rod 32 are fixedly installed at the four corners of the opposite sides of the base plate 11 and the top cover 12, respectively. A second connecting rod 33 and a second locking rod 34 are fixedly installed at the four corners of the top and bottom ends of the first fixing frame 13 and the second fixing frame 14, respectively. Multiple first locking rods 32 and second locking rods 34 are movably locked in the corresponding first connecting rods 31 and second connecting rods 33. Through the arrangement of the first connecting rods 31, first locking rods 32, second connecting rods 33 and second locking rods 34, the connection between the base plate 11, the top cover 12, the first fixing frame 13 and the second fixing frame 14 is more stable, and shaking is reduced.

[0029] The top of each of the multiple support plates 192 is provided with evenly distributed support grooves 41, and the top of each of the multiple support plates 192 is fixedly installed with evenly distributed brackets 42. By setting the support grooves 41 and brackets 42, the reagent can be supported and its stability can be improved.

[0030] The top of the cooling box 23 is fixedly equipped with symmetrically distributed fans 51, which achieve the effect of cooling the heat sink 25 and the pipe 22.

[0031] The outer sides of the cooling box 23 and the box body 101 are respectively provided with evenly distributed first heat dissipation holes 61 and second heat dissipation holes 62. By setting the first heat dissipation holes 61 and the second heat dissipation holes 62, heat is prevented from accumulating in the cooling box 23 and the box body 101.

[0032] Working principle: In actual use, by turning on the thermoelectric cooler 21, the temperature inside the constant temperature bath 102 is reduced. Then, by turning on the water pump 24, the clean water inside the pipe 22 flows. At this time, the heat generated at the bottom of the thermoelectric cooler 21 is transferred to the clean water inside the pipe 22. The clean water with a certain temperature comes to the cooling box 23 through the water pump 24. The heat is absorbed by the heat sink 25. The air force generated by the fan 51 can continuously cool the heat sink 25 and the clean water inside the pipe 22. After cooling, the clean water returns to the bottom of the thermoelectric cooler 21 to absorb its heat, thereby achieving the cooling treatment of the thermoelectric cooler 21 and improving its service life.

[0033] The staff then placed the reagents with the longest to shortest constant temperature time into the brackets 42 at the top of the base plate 11, the first fixing frame 13, and the second fixing frame 14. The base plate 11 and the second fixing frame 14 were installed by inserting the connecting plate 15 at the top of the base plate 11 into the limiting groove 17 at the bottom of the second fixing frame 14 and by pushing the locking plate 191 so that it passes through the locking groove 16 and the limiting groove 17. The installation of the first fixing frame 13 and the top cover 12 can be completed by repeating the above operation. When the staff needs to remove the reagent, they can remove the reagent by pressing the locking plate 191 to disengage it from the locking groove 16.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
