Description

Technical Field

[0001] The utility model relates to the technical field of rotary evaporators, in particular to a rotary evaporator which is convenient for disassembling and assembling a distillation bottle. Background Art

[0002] Rotary evaporator is a commonly used laboratory equipment, mainly used for continuous distillation of volatile solvents under reduced pressure. It is widely used in the fields of chemistry, pharmaceuticals, food and petrochemicals. The structure of the rotary evaporator includes a rotary motor, a distillation flask (rotary flask), a recovery flask, a heating pot, a condenser and other parts. The distillation flask is the core component of the rotary evaporator. It rotates at a certain speed driven by the rotary motor, thereby increasing the evaporation area and improving the evaporation efficiency.

[0003] At present, when the distillation flask is connected to the head of the rotary evaporator, the common fixing method is snap fixing. When the distillation flask is installed, the snap is fixed at the connection between the bottle mouth of the distillation flask and the head to fix the distillation flask. However, this snap fixing method is not only inconvenient to operate during use, but also has a poor fixing effect, and the distillation flask is prone to fall off. In view of this, we propose a rotary evaporator that is easy to disassemble and assemble the distillation flask. Utility Model Content

[0026] This embodiment provides a technical solution:

[0027] See also Figure 1-Figure 5 The rotary evaporator for assembling and disassembling a distillation flask comprises a rotary evaporator body 1; the rotary evaporator body 1 comprises a base 10, a base 11 is mounted on the top of the base 10, a head 12 is rotatably mounted on the front end surface of the base 11, a fixed tube 13 is fixedly mounted on the front end of the head 12, a joint 14 is fixedly mounted on the front end of the fixed tube 13, a distillation flask 15 is arranged on the front side of the joint 14, a bottle mouth 151 is mounted on the outer wall of the distillation flask 15, two limiting rings 152 are fixed on the outer wall of the bottle mouth 151, and the joint 14 is plugged and matched with the opening of the bottle mouth 151; the fixed tube 13 is fixedly mounted on the front end of the head 12, and a joint 14 is fixedly mounted on the front end of the fixed tube 13. A limiting assembly for fixing the distillation flask 15 is installed on the outer wall; the limiting assembly includes two symmetrical clamping rings 16 that are clamped on the outer wall of the fixed tube 13, and the two clamping rings 16 are detachably connected; a connecting seat 17 is fixed to the outer wall of the clamping ring 16, and a strip groove is opened on the connecting seat 17, and a threaded rod 19 is rotatably installed in the strip groove, and a connecting plate 18 that can move horizontally is threadedly connected to the threaded rod 19, and a clamping block 181 is fixed at the front end of the connecting plate 18, and the clamping block 181 is clamped on the outer wall of the bottle mouth 151, and the clamping block 181 is located between the two limit rings 152.

[0028] In this embodiment, support plates 161 are fixed at both ends of the clamp ring 16, and connecting bolts 162 are threadedly connected between two adjacent support plates 161. This design facilitates clamping the two clamp rings 16 on the fixed pipe 13, facilitates installation and fixing of the clamp rings 16, and is easy to disassemble.

[0029] In this embodiment, the clamp ring 16, the support plate 161 and the connection seat 17 are an integrally formed structure, and the clamp ring 16, the support plate 161 and the connection seat 17 are all made of plastic. The integrally formed clamp ring 16, the support plate 161 and the connection seat 17 have better connection strength, ensuring the reliability of the clamp ring 16, the support plate 161 and the connection seat 17 when in use, and the plastic material has the advantages of being light and easy to process.

[0030] In this embodiment, the overall shape of the clamp ring 16 is arc-shaped, and a plurality of anti-slip strips made of rubber are embedded on the arc-shaped inner wall of the clamp ring 16. This design facilitates the clamp ring 16 and the fixing tube 13 to be stably clamped and fixed.

[0031] In this embodiment, the overall shape of the clamp block 181 is semicircular, and the clamp block 181 is a plastic product. The semicircular design is conducive to the clamp block 181 being clamped on the outer wall of the bottle mouth 151, and the clamp block 181 made of plastic has the advantage of being easy to process.

[0032] In this embodiment, the outer wall of the connecting plate 18 is provided with two guide grooves 182 at both ends, and two guide rails 171 are fixed to the inner walls at both ends of the strip groove, and the guide rails 171 are slidably connected with the corresponding guide grooves 182.

[0033] In this embodiment, a dial head 191 is coaxially fixed at the end of the threaded rod 19, and the dial head 191 is a rubber product. The threaded rod 19 is conveniently rotated by the dial head 191, which improves the convenience of operation.

[0034] It should be added that the outer diameter of the limiting ring 152 in this embodiment is larger than the outer diameter of the bottle mouth 151 . This design can prevent the clamping block 181 and the outer wall of the bottle mouth 151 from slipping off, thereby ensuring the fixing effect of the clamping block 181 on the bottle mouth 151 .

[0035] During specific use, the user first aligns the bottle mouth 151 with the joint 14 and inserts it, and then the user turns the dial heads 191 on both sides in turn, and the dial heads 191 drive the threaded rod 19 to rotate. As the threaded rod 19 rotates, the connecting plate 18 slides along the strip groove, and the guide rail 171 slides along the guide groove 182. The connecting plate 18 also drives the clamping block 181 to move toward the bottle mouth 151, and the clamping block 181 is clamped on the outer wall of the bottle mouth 151 at the same time. Under the clamping of the clamping block 181, the distillation flask 15 can be fixed at the joint 14.
