Description

Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, in particular to a clamping mechanism for a rotary evaporation device. Background Art

[0002] Rotary evaporator, also known as rotary evaporator, is a commonly used laboratory equipment. It consists of a motor, a distillation flask, a heating pot and a condenser. It is mainly used for continuous distillation of volatile solvents under reduced pressure conditions and is used in chemistry, chemical industry and biomedicine.

[0003] The collecting bottle on the existing rotary evaporator is fixed to the condenser with a clamp after the bottle mouth of the collecting bottle is aligned with the interface of the condenser. The liquefied droplets flow along the wall of the condenser tube into the collecting bottle below and are received and stored by the collecting bottle.

[0004] However, if the collecting bottle and the condenser are only connected and fixed together by a clip, the collecting bottle and the condenser may become detached due to insufficient clamping force of the clip due to increased gravity as the amount of liquid in the collecting bottle gradually increases. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a clamping mechanism for a rotary evaporator to solve the technical problem that the collecting bottle and the condenser are only connected and fixed together by a clamp, which may cause the clamping force of the clamp to be insufficient due to the increase in gravity as the liquid in the collecting bottle gradually increases, thereby causing the collecting bottle to separate from the condenser.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping mechanism for a rotary evaporation device comprises a base, a first fixed block is fixedly connected to the bottom of the base, a driving rod is arranged in the first fixed block, a motor is movably connected to the driving rod, a gearbox is arranged in the motor, and a feeding bottle is snap-connected to the left side of the gearbox, a condenser is connected to the top of the feeding bottle, a first interface is fixedly connected to the bottom of the feeding bottle, a collecting bottle is arranged at the bottom of the first interface, a clamping block is arranged between the collecting bottle and the first interface, a telescopic tube is arranged between the clamping blocks, a spring is arranged on the outside of the telescopic tube, a second fixed block is fixedly connected to the outside of the clamping block, a second slider is fixedly connected to the second fixed block, and the first slider is movably connected in the second slider, a metal plate is fixedly connected in the second slider, a rotating bottle is arranged on the right side of the gearbox, and a water bath is arranged directly below the rotating bottle.

[0007] By adopting the above technical scheme, when the collecting bottle is aligned with the first interface, the mouth of the collecting bottle and the first interface are connected together by a clamp block, and a telescopic tube is fixedly connected between the clamp blocks. When the entire rotary evaporation device is in working condition, the droplets generated by liquefaction can enter the collecting bottle through the telescopic tube. At this time, the telescopic tube acts as a conduit, and a spring is arranged on the outside of the telescopic tube, and the spring can play a pulling and withdrawing role on the collecting bottle. When the liquid in the collecting bottle is at a certain level, the collecting bottle will continue to fall downward due to its weight. At the same time, the first slider will slide in the second slider. When the first slider is no longer in contact with the metal plate, the entire device is automatically powered off and no longer performs distillation. At this time, the collecting bottle can be removed to avoid the problem that after the liquid in the collecting bottle gradually increases, the gravity increases and the clamping force of the clamp is insufficient, thereby causing the collecting bottle to be separated from the condenser, thereby improving the practicality of the entire device.

[0008] The utility model is further configured that the clamping block is made of two groups of semicircular structures, and a rotating shaft is movably and rotatably connected between the clamping blocks.

[0009] By adopting the above technical solution, the clamping block can be connected to the first interface and the collecting bottle by breaking it apart, and the assembly method is relatively convenient.

[0010] The utility model is further configured such that a protrusion is fixedly connected to the first sliding block, and a sliding groove is provided in the second sliding block for matching the first sliding block and the protrusion.

[0011] By adopting the above technical solution, the first sliding block can move better in the second sliding block through the protrusion and the sliding groove.

[0012] The utility model is further configured such that a sensing block used with the metal plate is provided at the bottom of the first sliding block, and the sensing block is electrically connected to the motor.

[0013] By adopting the above technical solution, when the induction block is no longer in contact with the metal plate, the motor is automatically powered off, so that the entire rotary evaporation device no longer performs distillation work.

[0014] The utility model is further configured as follows: a control panel is provided on the base, a support rod is fixedly connected to the left side of the first fixing block, a fixing card is fixedly connected to the support rod, and the condenser is fixed to the support rod through the fixing card.

[0015] By adopting the above technical solution, the whole device is controlled to work through the control panel, and the condenser can be fixed on the first fixing block through the fixing card and the support rod.

[0016] The utility model is further configured that a liquid discharge pipe is arranged in the telescopic tube, and a feed port is arranged on the feed bottle.

[0017] By adopting the above technical solution, the liquid discharged from the first interface can be better guided into the collecting bottle through the liquid discharge pipe.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] The utility model connects the mouth of the collecting bottle and the first interface together through a clamping block when the collecting bottle is aligned with the first interface, and a telescopic tube is fixedly connected between the clamping blocks. When the whole rotary evaporation device is in a working state, droplets generated by liquefaction can enter the collecting bottle through the telescopic tube. At this time, the telescopic tube plays the role of a conduit, and a spring is arranged on the outer side of the telescopic tube, which can pull and withdraw the collecting bottle. When the liquid in the collecting bottle is at a certain level, the collecting bottle will continue to fall downward due to its weight. At the same time, the first slider will slide in the second slider. When the first slider is no longer in contact with the metal plate, the whole device is automatically powered off and no distillation is performed. At this time, the collecting bottle can be removed to avoid the problem that after the liquid in the collecting bottle gradually increases, the gravity increases and the clamping force of the clamp is insufficient, thereby causing the collecting bottle to separate from the condenser, thereby improving the practicality of the whole device.
