Abstract
Description
Technical Field
[0001] This utility model relates to the field of constant temperature water baths, and more specifically, to a high-precision constant temperature bath. Background Technology
[0002] In cutting-edge scientific research and industrial production fields such as chemical engineering, biopharmaceuticals, and materials science, a high-precision constant temperature environment is a key element to ensure the reliability of experimental data and the stability of product quality. As a core temperature control device, the performance of the constant temperature bath directly affects the experimental and production process.
[0003] Existing traditional constant temperature baths have significant drawbacks in practical applications: First, the lifting structure of the placement box is poorly designed and relies heavily on manual operation, which is not only inefficient but also unstable during lifting, making it easy for placed items to tip over and cause damage, leading to safety hazards such as liquid splashing. Second, the lack of a protective system allows external dust, particulate matter, and other impurities to easily enter the water bath, contaminating the constant temperature medium. At the same time, the lack of effective heat insulation and sealing measures results in serious heat loss, leading to large temperature fluctuations. This makes it difficult to meet the stringent requirements of high-precision experiments and production for a constant temperature environment, thereby affecting the accuracy of experimental results and product yield.
[0004] Therefore, a high-precision constant temperature bath needs to be redesigned to address the aforementioned issues. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a high-precision constant temperature bath.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] In a preferred embodiment, each of the transmission devices includes a transmission shaft, which is rotatably mounted in a fixed hole. One end of the transmission shaft extends into a corresponding groove and is fitted with a gear that meshes with a gear plate.

[0015] 2. This utility model, by setting up protective devices, can effectively block dust and other impurities from entering the water bath through the cooperation of torsion springs and sealing strips, while reducing heat loss and ensuring a constant temperature environment.

[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] Reference Figure 1-5A high-precision constant temperature bath includes a device body 1. Two mounting blocks 7 are symmetrically fixedly installed on the upper end face of the device body 1. A protective device is provided between the two mounting blocks 7. A water bath 11 is opened on the upper end face of the device body 1. Sliding grooves 9 are opened on the inner side wall of the water bath 11. A placement box 10 is slidably connected in the water bath 11. Toothed plates 16 are fixedly installed on both sides of the placement box 10, and the two toothed plates 16 are slidably connected in the two sliding grooves 9. Two fixing seats 4 are symmetrically fixedly installed on one side of the device body 1. A driving device is provided between the two fixing seats 4. Two fixing holes 12 are symmetrically opened on one side of the device body 1. The two fixing holes 12 are respectively connected to the two sliding grooves 9. A transmission device is provided in each fixing hole 12, and the output ends of the two transmission devices are respectively connected to the output ends of the driving device.
[0025] The protective device includes a connecting shaft 18, which is rotatably mounted between two mounting blocks 7. A protective plate 8 is fixedly mounted on the outer wall of the connecting shaft 18, and the protective plate 8 is located directly above the water bath 11. Torsion springs 19 are fixedly mounted on both sides of the protective plate 8, and one end of each torsion spring 19 is fixedly connected to one side of the mounting block 7. A sealing strip 17 is fixedly mounted on the bottom end of the protective plate 8, and the sealing strip 17 abuts against the upper surface of the equipment body 1.
[0026] The drive device includes a fixed shaft 5, which is rotatably mounted between two fixed seats 4. Two worm gears 6 are symmetrically arranged on the fixed shaft 5, and the two worm gears 6 are respectively connected to the output ends of the two transmission devices. It should be noted that the textures of the two worm gears 6 are opposite.
[0027] Each transmission device includes a transmission shaft 13, which is rotatably mounted in a fixed hole 12. One end of the transmission shaft 13 extends into a corresponding groove 9 and is fitted with a gear 14, which meshes with a gear plate 16. A worm gear 15 is fixedly mounted on the end of the transmission shaft 13 away from the gear 14, and the worm gear 15 meshes with a corresponding worm 6.
[0028] A mounting bracket 2 is fixedly installed on one side of the equipment body 1. A motor 3 is fixedly installed on the mounting bracket 2, and the output shaft of the motor 3 passes through the corresponding side of the fixed seat 4 and is fixedly connected to one end of the fixed shaft 5.
[0029] The placement box 10 is provided with multiple filter holes. The liquid in the water bath 11 can enter the placement box 10 through the filter holes, and at the same time, the filter holes can block and filter impurities in the placement box 10.
[0030] When this utility model is in use, the motor 3 is fixed to the mounting bracket 2. After being powered on, the output shaft drives the fixed shaft 5 to rotate, and the two worm gears 6 symmetrically mounted on it rotate synchronously. One end of the transmission shaft 13 of each transmission device is connected to the gear 14 that meshes with the toothed plate 16, and the other end is equipped with the worm wheel 15 that meshes with the worm gear 6. The two worm gears 6 have opposite grooves. When the worm gear 6 rotates, based on the meshing characteristics of the worm wheel 15 and the worm gear 6, the two worm wheels 15 rotate in opposite directions, driving the transmission shaft 13 and the gear 14 to rotate. The gear 14 meshes with the toothed plate 16, which is fixed on both sides of the placement box 10 and slidably embedded in the slide groove 9. When the gear 14 rotates, it provides a stable driving force to the placement box 10 through the toothed plate 16, so that it can rise and fall smoothly in the water bath 11, making it easy to place or take out items.
[0031] The connecting shaft 18 of the protective device is rotatably installed between two mounting blocks 7, and the protective plate 8 is fixed on its outer wall. When the protective plate 8 is opened, it can be opened by applying force manually, or by pushing the protective plate 8 when the placement box 10 is raised, so that it rotates around the connecting shaft 18. At this time, the torsion spring 19 is deformed by force and stores elastic potential energy. When it is not necessary to open, the torsion spring 19 releases elastic potential energy and returns to its original state, driving the protective plate 8 to rotate, so that the sealing strip 17 at the bottom of the protective plate 8 is tightly attached to the upper end surface of the equipment body 1. This can effectively block dust and other impurities from entering the water bath 11, and reduce heat loss in the bath, maintaining a stable constant temperature environment.
[0032] The water bath 11 of the main body 1 is used to hold liquids such as water to achieve a constant temperature function. Multiple filter holes on the placement box 10 ensure that the liquid can freely enter and exit. After the item is placed in the placement box 10, the motor 3 is operated to move the placement box 10 up and down in the water bath 11, so that the item is immersed in the liquid. In actual operation, the water bath 11 has a built-in heating or cooling device. The temperature sensor monitors the liquid temperature in real time and automatically adjusts the power according to the set parameters to ensure that the liquid temperature is constant, meet the high-precision constant temperature requirements, and provide a stable processing environment for the items in the placement box 10.
