Description

Technical Field

[0001] This utility model belongs to the technical field of rotary evaporators, and in particular relates to a rotary evaporator with good stability. Background Technology

[0002] A rotary evaporator is a highly efficient laboratory instrument widely used in chemistry, pharmaceuticals, food, and other fields. It is primarily used for the continuous distillation of volatile solvents under reduced pressure to concentrate, purify, or dry samples. A rotary motor drives a distillation flask containing the sample to rotate in a heating bath, while a vacuum pump reduces the internal pressure of the system, causing the solvent to evaporate at a lower temperature. The evaporated vapor is cooled into liquid in a condenser and flows into a collection flask, thus achieving solvent separation. This equipment is characterized by its ease of operation, rapid evaporation rate, and high efficiency, making it an indispensable tool in modern laboratories.

[0003] The problem with existing technology is that existing rotary evaporators are not stable enough. They usually rely on simple anti-slip pads and base designs, which cannot provide sufficient stability on complex or uneven experimental platforms. They are prone to slipping or tipping due to vibration or external forces, which affects experimental results and safety. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a rotary evaporator with good stability, which has the advantages of high stability and convenient operation. It solves the problem that existing rotary evaporators are insufficient in terms of stability, usually relying on simple anti-slip pads and base designs, which cannot provide sufficient stability on complex or uneven experimental platforms, and are prone to slipping or tipping due to vibration or external forces, affecting experimental results and safety.

[0005] This utility model is implemented as follows: a rotary evaporator with good stability includes a base plate and an evaporator. The evaporator is fixedly connected to the top of the base plate, and a control panel is fixedly connected to the front side of the evaporator. A receiving groove is opened inside the base plate, and a propulsion device is fixedly connected inside the receiving groove. A number of movable plates are placed inside the receiving groove, and an anti-slip pad is fixedly connected to the middle of the lower surface of the base plate.

[0006] In a preferred embodiment of this invention, the propulsion device includes a motor, a double-ended screw, and connecting blocks. The motor is fixedly connected to the rear side of the receiving groove, and the output end of the motor is fixedly connected to the double-ended screw. The front end of the double-ended screw is connected to the front side of the receiving groove via a bearing. Both the front and rear ends of the double-ended screw are threadedly connected to connecting blocks. Sliding grooves are provided on the left and right sides of the top of the connecting blocks. By setting up the propulsion device, the double-ended screw can be rotated by the motor, causing the connecting blocks on both sides to move forward and backward respectively.

[0007] In a preferred embodiment of this utility model, four movable plates are provided. The bottom of each movable plate is slidably connected to the bottom of the receiving groove. A slider is fixedly connected to the top of each movable plate on the side closest to each other. The slider is slidably connected to the inside of the sliding groove. The sliding groove cooperates with the movable plate. A support component is fixedly connected to the ends of each movable plate that are far apart from each other. By setting the slider and the sliding groove, the slider can move along the sliding groove, thereby pushing the movable plate to both sides.

[0008] In a preferred embodiment of this invention, the support assembly includes a support plate, springs, and a top plate. The top plate is fixedly connected to the side of each movable plate that is far apart from the others. Springs are fixedly connected to the bottom of each top plate. Six springs are provided and are evenly distributed at the bottom of the top plate. The bottom of each top plate is slidably connected to the support plate. The bottom of each spring is fixedly connected to the top of the support plate. By providing springs, the support plate can quickly contact the tabletop after the support assembly extends out of the receiving groove, thereby increasing the stability of the device.

[0009] As a preferred embodiment of this utility model, the top of the receiving groove is provided with a number of connecting grooves, and the top of the connecting block is fixedly connected with a number of stabilizing blocks. The stabilizing blocks are all slidably connected inside the connecting grooves. By setting the connecting grooves and stabilizing blocks, the connecting blocks can be moved along the connecting grooves to avoid deviation when the connecting blocks move.

[0010] As a preferred embodiment of this utility model, a number of anti-slip patterns are provided on both the front and rear sides of the lower surface of the base plate. The anti-slip patterns are equidistantly distributed on the lower surface of the base plate. By providing anti-slip patterns, the stability of the base plate when in contact with the table can be increased, and the base plate can be prevented from shifting on the table.

[0011] As a preferred embodiment of this invention, the bottom of the support plate near the double-headed screw is inclined at a certain angle. By setting the inclination angle, it becomes smoother to store the support component into the receiving groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model solves the problem of insufficient stability in existing rotary evaporators by setting up a base plate, evaporator, control panel, receiving tank, propulsion device, motor, double-headed screw, connecting block, anti-slip pad, slide groove, moving plate, slider, support assembly, support plate, spring, top plate, connecting groove, stabilizing block and anti-slip texture in combination. The existing rotary evaporators usually rely on simple anti-slip pad and base design, which cannot provide sufficient stability on complex or uneven experimental platforms. They are prone to slipping or tipping due to vibration or external force, which affects experimental results and safety.

[0014] 2. By setting anti-slip texture, this utility model can increase the stability of the base plate when it is in contact with the tabletop, and prevent the base plate from shifting on the tabletop. Attached Figure Description

Detailed Implementation

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown in the figure, the present invention provides a rotary evaporator with good stability, including a base plate 1 and an evaporator 2. The evaporator 2 is fixedly connected to the top of the base plate 1, and a control panel 3 is fixedly connected to the front side of the evaporator 2. A receiving groove 4 is opened inside the base plate 1, and a pushing device 5 is fixedly connected inside the receiving groove 4. A number of moving plates 8 are placed inside the receiving groove 4, and an anti-slip pad 6 is fixedly connected to the middle of the lower surface of the base plate 1.

[0023] refer to Figure 2 The propulsion device 5 includes a motor 501, a double-ended screw 502, and a connecting block 503. The motor 501 is fixedly connected to the rear side of the receiving groove 4. The output end of the motor 501 is fixedly connected to the double-ended screw 502. The front end of the double-ended screw 502 is connected to the front side of the receiving groove 4 through a bearing. Both the front and rear ends of the double-ended screw 502 are threadedly connected to the connecting block 503. The top left and right sides of the connecting block 503 are provided with sliding grooves 7.

[0024] Using the above scheme: by setting up the propulsion device 5, the double-headed screw 502 can be rotated by the motor 501, so that the connecting blocks 503 on both sides can move forward and backward respectively.

[0025] refer to Figure 2 There are four movable plates 8. The bottom of each movable plate 8 is slidably connected to the bottom of the receiving groove 4. The top of each movable plate 8 on the side closest to each other is fixedly connected to a slider 9. The slider 9 is slidably connected to the inside of the slide groove 7. The slide groove 7 is used in conjunction with the movable plate 8. The ends of each movable plate 8 that are far apart from each other are fixedly connected to a support component 10.

[0026] By adopting the above scheme, by setting slider 9 and slide groove 7, slider 9 can move along slide groove 7, thereby pushing moving plate 8 to both sides.

[0027] refer to Figure 3 The support assembly 10 includes a support plate 101, springs 102 and a top plate 103. The top plate 103 is fixedly connected to the side of the movable plates 8 that is far apart from each other. Springs 102 are fixedly connected to the bottom of the top plate 103. There are six springs 102, which are evenly distributed at the bottom of the top plate 103. The bottom of the top plate 103 is slidably connected to the support plate 101. The bottom of the springs 102 is fixedly connected to the top of the support plate 101.

[0028] The above solution is adopted: by setting spring 102, the support plate 101 can quickly contact the table after the support assembly 10 extends out of the receiving groove 4, thereby increasing the stability of the device.

[0029] refer to Figure 4 The top of the receiving groove 4 is provided with a number of connecting grooves 11, and the top of the connecting block 503 is fixedly connected with a number of stabilizing blocks 12. The stabilizing blocks 12 are all slidably connected to the inside of the connecting grooves 11.

[0030] By adopting the above solution, by setting the connecting groove 11 and the stabilizing block 12, the connecting block 503 can move along the connecting groove 11, thus avoiding the displacement of the connecting block 503 when it moves.

[0031] refer to Figure 3 The bottom surface of the base plate 1 has a number of anti-slip patterns 13 on both the front and back sides. The anti-slip patterns 13 are evenly distributed on the bottom surface of the base plate 1.

[0032] By adopting the above solution, the anti-slip texture 13 can be set to increase the stability of the base plate 1 when it contacts the tabletop, and prevent the base plate 1 from shifting on the tabletop.

[0033] refer to Figure 3 The bottom of the support plate 101 near the double-headed screw 502 is at a certain angle.

[0034] By adopting the above solution, by setting the tilt angle, it becomes smoother to store the support component 10 into the receiving slot 4.

[0035] The working principle of this utility model:

[0036] When using the device, first move it to the desktop, then use the control panel 3 to start the motor 501. The motor 501 then drives the double-ended screw 502 to rotate. At this time, the double-ended screw 502 will drive the connecting block 503 to move along the connecting groove 11. Since the threads on both sides of the double-ended screw 502 turn in opposite directions, the connecting blocks 503 on both sides move in opposite directions. Then the slider 9 will move along the sliding groove 7. Subsequently, the slider 9 will drive the moving plate 8 to move to the left and right sides of the base plate 1. When the moving plates 8 on both sides extend to the outermost end, the spring 102 will cause the support plate 101 to quickly contact the ground, thereby increasing the overall stability of the device. The anti-slip texture 13 and anti-slip pad 6 design can increase the friction between the base plate 1 and the placement surface, reducing the risk of the device sliding during operation. After the device is stably placed on the desktop, the evaporator 2 can be used for subsequent operations.

[0037] In summary, this highly stable rotary evaporator, through the coordinated use of a base plate 1, evaporator 2, control panel 3, receiving tank 4, propulsion device 5, motor 501, double-headed screw 502, connecting block 503, anti-slip pad 6, sliding groove 7, moving plate 8, slider 9, support assembly 10, support plate 101, spring 102, top plate 103, connecting groove 11, stabilizing block 12, and anti-slip texture 13, solves the problem of insufficient stability in existing rotary evaporators. These evaporators typically rely on simple anti-slip pads and base designs, which cannot provide sufficient stability on complex or uneven experimental platforms, and are prone to sliding or tipping due to vibration or external forces, affecting experimental results and safety.
