Description

Technical Field

[0001] This utility model relates to the technical field of heating and stirring devices, and in particular to a heating and stirring device for biological laboratories. Background Technology

[0002] A biology laboratory is a complex environment encompassing multiple fields and functions, primarily used for scientific research and experimental teaching. Within a biology laboratory, scientists utilize advanced instruments and equipment to conduct in-depth research in fields such as biochemistry, molecular biology, and genetics.

[0003] Patent document CN221207913U discloses a heating stirrer for a biological laboratory, relating to the field of biological experiments. It includes a base, a fixed frame at the top of the base, a heating and stirring assembly at the bottom of the fixed frame, a support frame at the top of the base, a sliding strip connected to the bottom of the support frame, and a corresponding groove on the top of the base for the sliding strip. Two sets of fixed and rotating components are also provided at the top of the support frame. This invention, by using two sets of fixed and rotating components, allows for easy removal of the stirred container after the solution in one container has been heated and stirred. By pulling the handle, the support plate can be easily moved, allowing the stirred container to be moved away and the unstirred container to the bottom of the heating and stirring assembly for continued heating and stirring. The removed stirred solution causes the container to rotate, causing it to tilt and pour out its contents, facilitating easy removal of the solution.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In actual use, the above solutions can only store two measuring cups at the same time, lacking a mechanism for storing and placing multiple measuring cups. Furthermore, the above solutions fix the measuring cups by setting up several electric push rods, which requires the measuring cups to be precisely placed at the corresponding positions of the electric push rods. This method is cumbersome to operate, has a complex structure, and the setting of numerous electrical devices increases the production cost and energy consumption of the device. Utility Model Content

[0005] This utility model discloses a heating stirrer for biological laboratories, which aims to solve the technical problems of existing heating stirrers being unable to store multiple measuring cups and having a complex structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heating stirrer for a biological laboratory includes a base, an mounting column fixedly mounted on the upper surface of the base, an mounting cavity formed inside the housing of the mounting column, a lead screw vertically mounted inside the mounting cavity, a first motor fixedly mounted on the upper end of the mounting column, the output shaft of the first motor extending into the mounting cavity and fixedly connected to the upper end of the lead screw, a threaded sleeve threadedly connected to the surface of the lead screw, a sliding strip opening extending through the surface of the mounting column formed on the left inner wall of the mounting cavity, an mounting plate fixedly connected to the left side surface of the threaded sleeve through the sliding strip opening, and a heating and stirring mechanism provided on the surface of the mounting plate;

[0008] The heating and stirring mechanism includes a second motor fixedly mounted on the upper surface of the mounting plate. The output shaft of the second motor extends to the lower surface of the mounting plate and is fixedly connected to a stirring rod. A stirring blade is fixedly connected to the lower end of the stirring rod. A spiral electric heating tube sleeved on the surface of the stirring rod is fixedly connected to the lower surface of the mounting plate. A collar is rotatably connected to the surface of the mounting column via a damping shaft. Four placement rings arranged in a circumferential array are fixedly connected to the surface of the collar via a connecting rod. A measuring cup is placed inside one of the four placement rings. A fixing mechanism is provided on the upper surface of the base.

[0009] In a preferred embodiment, a guide slider is provided on the right side surface of the threaded sleeve, and a guide groove for the guide slider to slide is provided on the right inner wall of the mounting cavity.

[0010] By setting a guide slider, the threaded sleeve can move up and down in a directional manner through the rotation of the screw under the guidance of the guide slider.

[0011] In a preferred embodiment, the number of stirring blades is four, and the four stirring blades are arranged in a circumferential array on the surface of the stirring rod.

[0012] In a preferred embodiment, the fixing mechanism includes a mounting groove formed on the upper surface of the base, with bidirectional threaded rods rotatably connected to the inner walls of both sides of the mounting groove, and a rotating opening extending through the mounting groove on the left side surface of the base. An operating rod fixedly connected to the left end of the bidirectional threaded rod is rotatably connected to the inner wall of the rotating opening, and two symmetrical threaded blocks are threadedly connected to the surface of the bidirectional threaded rod, with two symmetrical clamping plates fixedly connected to the upper surfaces of the two threaded blocks.

[0013] The clamps allow for the holding and securing of the measuring cup within the placement ring.

[0014] In a preferred embodiment, the threaded block is provided with limit sliders on both the front and back sides, and the inner front wall and inner rear wall of the mounting groove are provided with limit grooves for the limit sliders to slide.

[0015] By setting a limit slider, the threaded block can drive the clamping plate to move in a specific direction through the rotation of the bidirectional threaded rod under the guidance of the limit slider.

[0016] In a preferred embodiment, flexible protective pads are provided on the opposite surfaces of both clamps.

[0017] The flexible protective pad can protect the surface of the measuring cup when the clamp is in contact with it.

[0018] As can be seen from the above, the heating stirrer for biological laboratories provided by this utility model has the following technical effects.

[0019] Firstly, the first motor reverses to drive the mounting plate and stirring rod upwards. Without the obstruction of the stirring rod, it pushes the placement ring to rotate on the surface of the mounting column, thus completing the replacement of the placement ring. This allows the device to store and set aside multiple measuring cups, further improving its practicality.

[0020] Secondly, rotating the operating lever drives the bidirectional threaded rod to rotate. Under the guidance of the limiting slider, the two threaded blocks drive the two clamping plates to move through the rotation of the bidirectional threaded rod until the two clamping plates clamp and fix the surface of the measuring cup, thereby achieving the purpose of fixing the measuring cup. The operation is simple and the device does not require the installation of other electrical equipment to achieve the fixing effect, which greatly reduces the production economy and effort of the device.

[0028] The heating and stirring mechanism includes a second motor 7 fixedly mounted on the upper surface of the mounting plate 6. The output shaft of the second motor 7 extends to the lower surface of the mounting plate 6 and is fixedly connected to a stirring rod 8. A stirring blade 9 is fixedly connected to the lower end of the stirring rod 8. There are four stirring blades 9 arranged in a circumferential array on the surface of the stirring rod 8. A spiral electric heating tube 10 is fixedly connected to the lower surface of the mounting plate 6 and sleeved on the surface of the stirring rod 8. A collar 11 is rotatably connected to the surface of the mounting column 2 through a damping shaft. Four placement rings 12 arranged in a circumferential array are fixedly connected to the surface of the collar 11 through a connecting rod. A measuring cup 13 is placed inside one of the four placement rings 12. A fixing mechanism is provided on the upper surface of the base 1.

[0029] Reference Figure 2 In a preferred embodiment, a guide slider 14 is provided on the right side surface of the threaded sleeve 5, and a guide groove for the guide slider 14 to slide is provided on the right inner wall of the mounting cavity. Under the guidance of the guide slider 14, the threaded sleeve 5 can move up and down in a directional manner by rotating the screw 3.

[0030] Reference Figure 2 and Figure 3In a preferred embodiment, the fixing mechanism includes a mounting groove formed on the upper surface of the base 1. Two bidirectional threaded rods 15 are rotatably connected to the inner walls of both sides of the mounting groove. A rotating opening extending through the mounting groove is formed on the left side surface of the base 1. An operating rod fixedly connected to the left end of the bidirectional threaded rod 15 is rotatably connected to the inner wall of the rotating opening. Two symmetrical threaded blocks 16 are threadedly connected to the surface of the bidirectional threaded rod 15. Two symmetrical clamping plates 17 are fixedly connected to the upper surfaces of the two threaded blocks 16. The clamping plates 17 can clamp and fix the measuring cup 13 inside the placement ring 12.

[0031] Reference Figure 2 and Figure 3 In a preferred embodiment, the threaded block 16 is provided with limit sliders 18 on both the front and back sides, and the inner front wall and inner rear wall of the mounting groove are provided with limit grooves for the limit sliders 18 to slide. Under the guidance of the limit sliders 18, the threaded block 16 can drive the clamping plate 17 to move in a directional manner through the rotation of the bidirectional threaded rod 15.

[0033] Working principle: The measuring cup 13 is placed on the placement ring 12, and the operating lever is rotated to drive the bidirectional threaded rod 15 to rotate. Under the guidance of the limiting slider 18, the two threaded blocks 16 drive the two clamping plates 17 to move through the rotation of the bidirectional threaded rod 15, until the two clamping plates 17 clamp and fix the surface of the measuring cup 13, thereby fixing the measuring cup 13 and preventing it from shaking during subsequent stirring operations. During the heating and stirring operation, the first motor 4 drives the lead screw 3 to rotate, and the threaded sleeve 5 drives the mounting plate 6 to move down under the rotation of the lead screw 3, until the stirring rod 8 moves into the measuring cup 13. At this time, the second motor 7 and the spiral heating tube 10 operate simultaneously. The operation of the second motor 7 drives the stirring rod 8 and the stirring blade 9 to stir and mix the solution in the measuring cup 13, and heats it under the action of the spiral heating tube 10 to achieve the purpose of heating and stirring. When the heating and stirring are completed and it is necessary to let it stand and cool down, the first motor 4 reverses and drives the mounting plate 6 and the stirring rod 8 to move upward. Without the obstruction of the stirring rod 8, it pushes the placement ring 12 to drive the collar 11 to rotate on the surface of the mounting column 2, thus completing the replacement of the placement ring 12. This allows the device to store and let multiple measuring cups 13 stand.
