Abstract
Description
Technical Field
[0001] This utility model belongs to the field of experimental shaker technology, specifically relating to a constant temperature shaker. Background Technology
[0002] Currently, the constant temperature shaker is a multi-purpose biochemical apparatus, an indispensable laboratory piece of equipment for precise culture and preparation in scientific research, education, and production departments such as plants, biology, microorganisms, genetics, virology, environmental protection, and medicine. It is suitable for the shaking culture of various liquid and solid compounds such as biological, biochemical, cell, and bacterial strains in universities, oil and chemical, health and epidemic prevention, and environmental monitoring departments. Existing constant temperature shakers combine a constant temperature incubator, a shaker, and a shaker. In use, a vessel is placed on the shaker, and the shaker drives the shaker and the vessel to shake. At the same time, the constant temperature incubator maintains the culture temperature of the vessel, thus achieving shaking culture.
[0003] However, existing constant-temperature shakers generally suffer from poor clamping stability at high vibration frequencies or amplitudes, leading to sample tubes loosening or falling off, failing to meet the requirement for sufficient sample oscillation. Furthermore, shakers typically use fixed-height mounting brackets or limiting structures, only suitable for beakers of a single size (e.g., fixed capacity). When experiments require changing beakers of different heights or sizes, stable clamping cannot be achieved using fixed-height mounting brackets or limiting structures, resulting in reduced experimental efficiency or even making the experiment impossible to complete.
[0004] Therefore, how to provide a constant temperature shaker that can quickly clamp different types of beakers has become a problem that those skilled in the art need to consider. Utility Model Content
[0005] In view of this, the present invention provides a constant temperature shaker. The present invention improves the stability of beakers of different sizes during shaking by setting an anti-slip layer and a detachable limiting device, and facilitates disassembly and replacement.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A constant temperature shaker includes an insulated box body with a temperature control system. An insulated box cover is rotatably mounted on the front of the insulated box body. Inside the insulated box body are an oscillation mechanism, columns, an iron mounting frame, and several limiting plates. The upper surface of the oscillation mechanism is covered with a viscous anti-slip layer. The columns are positioned at the four corners of the oscillation mechanism. Guide holes are provided at the corners of the mounting frame corresponding to the columns. Threaded holes are laterally opened in the guide holes and communicate with them. Fastening bolts are installed in the threaded holes. Several hollow rectangular grooves are evenly distributed on the surface of the mounting frame. Positioning holes are provided diagonally in the rectangular grooves. Insertion protrusions are provided diagonally in the limiting plates corresponding to the positioning holes. Magnetic strips are provided on the bottom surface of the limiting plates corresponding to the rectangular grooves. A limiting hole for beaker positioning is provided in the center of the limiting plates.
[0008] Furthermore, the oscillation mechanism includes a base, a spring, a drive mechanism, and a placement platform. The base is fixed to the bottom of the insulation box, the drive mechanism is fixed to the center of the base, the top of the drive mechanism is fixedly connected to the placement platform, and spring mounting seats are provided at the four corners of the base and the placement platform. The two ends of the spring are fixedly connected to the base and the placement platform, respectively.
[0009] Furthermore, the drive mechanism includes a drive motor and a drive base. A hinge seat is mounted on the shaft of the drive motor, and an L-shaped drive shaft is mounted on the side of the hinge seat. The hinge seat and the bottom end of the drive shaft are fastened together by an angle adjustment bolt. The drive base is installed at the bottom center of the placement platform, and a through hole is provided at the center of the drive base. The drive shaft is rotatably disposed within the through hole.
[0010] Furthermore, the upper surface of the limiting plate is provided with insertion holes for fingers to be inserted on both sides of the limiting hole.
[0011] Furthermore, the inner ring of the limiting hole of the limiting plate is covered with a rubber pad.
[0012] The beneficial effects of this utility model are as follows: The anti-slip layer of the oscillation mechanism significantly increases the friction between the bottom of the beaker and the oscillation mechanism; the plug-in limiting plate and mounting bracket allow for flexible adjustment of the mounting bracket position according to the beaker height, enabling adaptation to beakers of different heights; different limiting plates can be used for beakers of different diameters, thus fixing straight cylindrical or conical beakers of different sizes, and stably holding the beaker under the high-frequency and large-amplitude oscillation of the shaker; the magnetic installation method enables quick installation and removal of the limiting plate, and the plug-in holes on both sides of the limiting hole on the upper surface of the limiting plate further simplify the removal process, allowing experimenters to pick up and put down the plate by hand without the aid of tools, greatly improving the efficiency of experimental preparation and cleaning.

[0022] like Figure 1-5As shown, this embodiment discloses a constant temperature shaker, including an insulated box 1 with a temperature control system. An insulated box cover 2 is rotatably mounted on the front of the insulated box 1. Inside the insulated box 1 are an oscillation mechanism, columns 3, an iron mounting frame 4, and several limiting plates 5. The upper surface of the oscillation mechanism is provided with a viscous anti-slip layer. In this embodiment, the anti-slip layer is a rubber-based anti-slip coating, a composite material coating composed of a rubber elastomer, a tackifying resin (e.g., terpene resin), and silica filler. This coating is resistant to acid and alkali corrosion, increases the friction at the bottom of the beaker, and prevents the beaker 20 from sliding relative to the oscillation mechanism. The columns 3 are fixed at the four corners of the oscillation mechanism. Guide holes are provided at the corners of the mounting frame 4 corresponding to the columns 3. Threaded holes are opened laterally in the guide holes and communicate with them. Fastening bolts 6 are installed in the threaded holes. The height of the mounting frame 4 can be adjusted using the fastening bolts 6 to accommodate beakers 20 of different heights.
[0023] The surface of the mounting bracket 4 is evenly provided with several hollow rectangular grooves. Positioning holes are provided at the diagonal corners of the rectangular grooves. The diagonal corners of the limiting plate 5 are provided with insertion protrusions 7 corresponding to the positioning holes. The bottom surface of the limiting plate 5 is provided with magnetic strips 8 installed in the rectangular grooves. The center of the limiting plate 5 is provided with a limiting hole 9 for positioning a beaker. The inner ring of the limiting hole 9 is covered with a rubber pad 10. The positioning hole is used for quick installation and positioning of the limiting plate 5. The setting of the magnetic strip 8 can ensure that the limiting plate 5 is firmly fixed in the rectangular groove and is easy to disassemble. The upper surface of the limiting plate 5 is provided with plug-in holes 19 on both sides of the limiting hole 9 for easy insertion and removal by the experimenter.
[0024] In a preferred embodiment of the present invention, the oscillation mechanism includes a base 11, a spring 12, a drive mechanism, and a placement platform 13. The base 11 is fixed to the bottom of the insulation box 1, the drive mechanism is fixed to the center of the base 11, and the top of the drive mechanism is fixedly connected to the placement platform 13. Spring mounting seats are welded to the four corners of the base 11 and the placement platform 13. In this embodiment, the spring 12 is a cylindrical helical spring, and the two ends of the spring 12 are fixedly connected to the base 11 and the placement platform 13 respectively.
[0025] The drive mechanism in this embodiment includes a drive motor 14 and a drive base 15. A hinge base 16 is mounted on the shaft of the drive motor 14, and an L-shaped drive shaft 17 is mounted on the side of the hinge base 16. The bottom ends of the hinge base 16 and the drive shaft 17 are fastened together by an angle adjusting bolt 18. The drive base 15 is installed at the bottom center of the placement platform 13, and a through hole is provided at the center of the drive base 15. The drive shaft 17 is rotatably disposed in the through hole. By starting the drive motor 14, the hinge base 16 can be rotated, which in turn drives the L-shaped drive shaft 17 to rotate. In conjunction with the spring 12, the placement platform 13 produces an oscillation effect. The angle adjusting bolt 18 can adjust the angle between the hinge base 16 and the drive shaft 17, thereby changing the amplitude of the oscillation.
