Description

Technical Field

[0001] The utility model belongs to the field of chemical reagents, and in particular relates to a chemical reaction water bath constant temperature heating device. Background Art

[0002] Constant temperature water baths are widely used in drying, concentration, distillation, impregnation of chemical reagents, impregnation of medicines and biological preparations. They can also be used for constant temperature heating in water baths and other temperature tests. They are essential tools for educational and scientific research in biology, genetics, viruses, aquaculture, environmental protection, medicine, health, biochemical laboratories, and analysis rooms.

[0003] The Chinese utility model patent is CN217042664U, which discloses a constant temperature water bath pot, including a pot body, the upper end of which is open; a pot cover, which is provided with at least one placement opening for placing a beaker; a support frame, which is located in the pot body, and the upper surface of which is provided with a plurality of water-permeable holes; a support plate, which is mounted on the top of the support frame, and the position of the support plate corresponds to the position of the placement opening; an adjustment device is provided on the support plate and the support frame, which is used to adjust the relative vertical distance between the support plate and the support frame; beakers of different heights are placed on the support frame from the placement opening, and the relative distance between the support plate and the support frame in the vertical direction can be adjusted by the adjustment device, that is, the spacing between the support plate and the placement opening is reduced;

[0004] The above design aims to solve the problem that the existing constant temperature water bath cannot heat test tubes and beakers of different heights and lengths. The spacing between the support plate and the placement port is controlled by setting a support plate and an adjustment device. However, this design has certain problems when used.

The top plate 2 is provided with a placement groove 51, and the bottom end of the top plate 2 is provided with a moving groove 52. The placement groove 51 is connected to the moving groove 52, and the outer cover 54 is provided with a middle cover 55.

By installing the top plate 2 to the top of the main body 1, the beaker and the test tube are placed on the surface of the placement plate 3, and then the water level inside the main body 1 is observed by using the display mechanism 7, and the bottom part of the test tube and beaker is limited by using the limit mechanism 6, and the top part of the test tube and beaker is limited by using the top plate 2 and the protection mechanism 5. , the caliber size of the test tube itself, to randomly combine the inner cover 56, the middle cover 55 and the outer cover 54 of the corresponding size, by pressing the moving part 53 on the side of the assembled top cover component into the inside of the moving groove 52, and then rotating the assembled top cover assembly, so that the moving part 53 can slide stably in the inside of the moving groove 52, and the assembly and installation of the top cover is completed, which can limit the top part of the test tube or beaker of the corresponding size, and can also reduce the loss of internal high-temperature water vapor, making the constant temperature effect more perfect, thereby greatly improving the working quality of the equipment itself.

[0031] By the attached Figure 4 As shown, in this embodiment, the connection method between the inner cover 56 and the middle cover 55, and the middle cover 55 and the outer cover 54 is consistent with the connection method between the outer cover 54 and the top plate 2, which is used to quickly adjust the overall inner diameter size. During use, the inner cover 56, the middle cover 55 and the outer cover 54 can be quickly combined according to the size of the top diameter of the test tube or beaker, so that the top cover part can better fit the top part of the test tube or beaker.

[0032] By the attached Figure 4As shown, in this embodiment, the surfaces of the outer cover 54, the middle cover 55 and the inner cover 56 are fixedly mounted with a toggle plate for quickly rotating and toggling the plate. During use, it is more convenient and labor-saving to rotate the middle cover 55, the outer cover 54 and the inner cover 56.

[0033] By the attached Figure 5 As shown, in this embodiment, the limiting mechanism 6 includes an outer ring plate 61, a middle ring plate 62, an inner ring plate 63, a limiting rod 64, a limiting groove 65 and a spring 66.

The limiting rods 64 are symmetrically fixed on the bottom ends of the outer ring plate 61, the middle ring plate 62 and the inner ring plate 63, and the limiting grooves 65 are symmetrically arranged inside the placement plate 3. The limiting rods 64 are slidably plugged into the limiting grooves 65, and the bottom ends of the outer ring plate 61, the middle ring plate 62 and the inner ring plate 63 are all provided with springs 66.

[0034] During use, a beaker or test tube filled with chemical reagents is placed on the surface of the placement plate 3, and the weight of the beaker itself and the weight of the internal reagents are then used to squeeze the outer ring plate 61, the middle ring plate 62, and the inner ring plate 63. Due to the size limitation of the bottom end of the beaker itself, the outer ring plate 61, the middle ring plate 62 or the inner ring plate 63 at the bottom will be automatically squeezed, so that the outer ring plate 61, the middle ring plate 62 and the inner ring plate 63 will be automatically pressed downward, and the outer wall of the bottom part of the test tube is limited by the groove inside the placement plate 3. In addition, due to the use of the spring 66, the outer ring plate 61, the middle ring plate 62 and the inner ring plate 63 can be quickly reset for easy reuse.

[0035] By the attached Figure 5 As shown, in this embodiment, holes of corresponding sizes and depths are provided at the bottom ends of the outer ring plate 61, the middle ring plate 62 and the inner ring plate 63 inside the placement plate 3. When in use, beakers and test tubes of different calibers and sizes drive different numbers of plates and different moving spacings of the plates, allowing the equipment to better fit beakers and test tubes of different sizes.

[0036] By the attached Figure 6 As shown, in this embodiment, the display mechanism 7 includes a mounting seat 71, a fixing seat 72, a connecting tube 73 and a display tube 74.

[0037] During use, the required water source is injected into the main body 1, and then the mounting seat 71 and the fixing seat 72 are used to connect with the inner wall of the main body 1. When the water source enters the heating component 4, the water source automatically enters the display tube 74 according to the principle of the communicating vessel, and the water level inside the main body 1 is directly reflected in the display tube 74, which is convenient for real-time observation of the water level.

[0038] By the attached Figure 6 As shown, in this embodiment, the display tube 74 is made of a transparent acrylic tube, and a scale is set on the outer surface of the display tube 74 for quickly detecting the water level height inside the main body 1. During use, it is convenient to clearly observe the height of the water level inside the display tube 74 to prevent the water level from exceeding the surface of the placement plate 3 and affecting the heating and constant temperature operations of the test tubes and beakers.

[0039] By the attached Figure 1 As shown, in the present embodiment, circular holes are symmetrically and evenly provided inside the placement plate 3, and fitting grooves are symmetrically provided on the inner side surfaces of the placement plate 3, which are used to cooperate with the heating component 4 to maintain a constant temperature and heat the test tubes and beakers on the surface of the placement plate 3. During use, the placement plate 3 can be better placed inside the main body 1, and the placement plate 3 can also better fit the outer surface of the heating component 4. When the heating component 4 subsequently heats the water source inside the main body 1, the test tubes on the surface of the placement plate 3 can be better heated.
