Description

Technical Field

[0001] This utility model belongs to the field of bio-refrigeration technology, and in particular relates to a shaking mechanism for a rapid refrigeration system. Background Technology

[0002] In the field of biorefrigeration technology, freeze-thaw machines are used to preserve biological samples such as cells and proteins. Through rapid freezing and thawing processes, chemical degradation and physical damage to biological samples can be effectively avoided, maintaining their biological activity and stability. However, existing freezers cool from the outer layer first, and the resulting solid ice hinders the rapid cooling of the inner layers. Furthermore, existing freezers typically use cam mechanisms and four-bar linkages to cause the chamber to rock, resulting in relatively complex mechanical processes. The cam mechanism also requires springs for reset, which reduces the mechanical strength of the springs at extremely low temperatures, leading to poor stability at low temperatures. Summary of the Invention

To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0036] This utility model embodiment provides a shaking mechanism for a rapid cooling system, comprising:

[0037] Platform 1, a sliding component 2 is provided on one side of the platform 1, and a mounting hole 1a is provided on the platform 1, the mounting hole 1a passing through the platform 1 along a first direction A;

[0038] The housing 3 is located along the first direction A on the side of the platform 1 near the sliding component 2 and spaced apart from the platform 1. The housing 3 is connected to the sliding component 2 and can slide on the platform 1. The side of the housing 3 near the platform 1 is provided with a limiting groove 3a.

[0039] Crank assembly 4 includes:

[0040] Crankshaft 41, the crankshaft 41 passing through the mounting hole 1a of the platform 1;

[0041] The follower rotor 42 is fixedly connected to one end of the crankshaft 41 near the housing 3 and is disposed in the limiting slide groove 3a of the housing 3. The central axis of the follower rotor 42 is parallel to and does not coincide with the central axis of the crankshaft 41.

[0042] The drive mechanism 5 is connected to the end of the crankshaft 41 away from the housing 3 and can drive the crankshaft 41 to rotate.

[0043] In a specific embodiment, such as Figure 3 As shown, the box body 3 and the platform 1 are spaced apart in the vertical direction, and the sliding component 2 is provided between the box body 3 and the platform 1. The box body 3 slides on the platform 1 through the sliding component 2.

[0044] The mounting hole 1a of the platform 1 extends through the platform 1 in the vertical direction. The crankshaft 41 passes through the mounting hole 1a, with the follower rotor 42 at the upper end and the drive mechanism 5 at the lower end. The follower rotor 42 at the upper end is located in the limiting groove 3a on the lower side of the housing 3. During operation, the drive mechanism 5 drives the crankshaft 41 to rotate, and the crankshaft 41 drives the upper follower rotor 42 to rotate. Since the central axis of the follower rotor 42 is parallel to and does not coincide with the central axis of the crankshaft 41, it can be understood that the follower rotor 42 can make circular motion around the central axis of the crankshaft 41. Since the follower rotor 42 is located in the limiting slide groove 3a, it can drive the housing 3 to move on the sliding assembly 2. During cooling, the outer layer of the housing 3 freezes first, and a solid-liquid mixture is first formed between the inner and outer layers of the housing 3. At this time, the shaking mechanism for the rapid cooling system is activated to make the housing 3 slide, which improves the solid-liquid uniformity and heat exchange rate, thereby promoting the synchronous cooling of the inner and outer layers of the housing 3. This structure is simple and easy to implement. The crank assembly 4 greatly reduces the complexity of the mechanical process, reduces the manufacturing cost, and increases practicality.

[0045] Furthermore, the outer side of the box 3 is made of thermal insulation material to ensure that the low-temperature environment inside the box 3 is not affected by the external environment. For example, foam material can be used for thermal insulation.

[0046] This application does not limit the shape of the limiting slide groove 3a, and the shape of the limiting slide groove 3a can be adaptively adjusted according to actual needs. In a specific embodiment, the sliding component 2 extends along the second direction B;

[0047] The limiting groove 3a is an elongated groove that extends along a third direction C, which is perpendicular to the second direction B.

[0048] like Figure 1 and Figure 3 As shown, when the crankshaft 41 rotates, it can drive the follower rotor 42 to make a circular motion around the central axis of the crankshaft 41. Since the limiting groove 3a is an elongated hole, when the follower rotor 42 moves, it can limit the housing 3 to move only in the direction perpendicular to the extension direction of the limiting groove 3a, thereby realizing the sliding of the housing 3 on the sliding assembly 2. In this structure, the follower rotor 42 in the crank assembly 4 is connected to the limiting groove 3a, which can effectively reduce friction and increase transmission performance.

[0049] This application does not limit the specific configuration of the sliding component 2. In a specific embodiment, the sliding component 2 includes:

[0050] Slider 21, one side of which is fixedly connected to the housing 3, and the other side of which is provided with a groove;

[0051] The slide rail 22 extends along the second direction B and is fixedly connected to the platform 1. The slide rail 22 is slidably embedded in the groove of the slider 21.

[0052] The sliding component 2 provides low resistance and high load-bearing capacity. In this embodiment, the number and position of the slider 21 and the slide rail 22 are not limited. In one embodiment, such as... Figure 3 As shown, the rocking mechanism for the rapid cooling system includes at least two sets of sliding components 2, which are spaced apart along a third direction C.

[0053] Each of the sliding components 2 includes one of the slide rails 22 and at least two of the sliders 21.

[0054] The use of two sets of slider 21 components, both of which are single-rail double slider 21 structures, can increase the stable transmission efficiency and load-bearing capacity of the rocking mechanism used in the rapid cooling system, ensuring that the box 3 slides smoothly, stably, and reliably, thereby improving the stability of the rocking mechanism used in the rapid cooling system. This is beneficial for dispersing the solid-liquid mixture in the box 3 and accelerating the rapid freezing of the inner layer of the box 3.

[0055] Furthermore, a limiting block 6 is provided on the side of the box 3 near the platform 1, and the limiting block 6 is provided with the limiting groove 3a.

[0056] like Figure 4 and Figure 5 As shown, the lower side of the housing 3 is provided with the limiting block 6. With the limiting block 6 structure design, after the limiting groove 3a is worn, the limiting block 6 component can be directly replaced, which is beneficial for later maintenance and extends the service life of the housing 3.

[0057] Furthermore, the crank assembly 4 also includes a bearing housing 43, which is fixedly installed in the mounting hole 1a of the platform 1;

[0058] The bearing housing 43 is provided with two bearings 44, which are spaced apart along the first direction A, and any one of the bearings 44 is fitted onto the crankshaft 41.

[0059] The design employs a dual-bearing 44 structure to ensure that the crankshaft 41 meets the requirements of coaxiality and dynamic balance during transmission, thereby increasing the transmission stability of the crankshaft 41 and preventing shaking during transmission.

[0060] Furthermore, the outer side of the bearing seat 43 is provided with a protrusion 431, and the protrusion 431 is located on the side of the platform 1 near the housing 3, such as... Figure 4 and Figure 5 As shown, the protrusion 431 facilitates the quick installation of the crank assembly 4, and the protrusion 431 can prevent the crank assembly 4 from loosening under the action of gravity.

[0061] Furthermore, the drive mechanism 5 includes a drive motor, and the drive motor includes an output shaft 51.

[0062] The output shaft 51 is connected to the crankshaft 41 via a diaphragm coupling 7.

[0063] like Figure 5 As shown, when the drive motor is turned on during operation, the output shaft 51 of the drive motor rotates. The diaphragm coupling 7 ensures that the crankshaft 41 rotates synchronously with the output shaft 51, thereby ensuring that the structure drives the crankshaft 41 to rotate.

[0064] Furthermore, it also includes a mounting bracket 8, which is fixedly connected to the side of the platform 1 away from the housing 3. The mounting bracket 8 is U-shaped and has a second mounting hole. The output shaft 51 of the drive motor passes through the second mounting hole. This structure can provide support and ensure the stability of the crank assembly 4 when it rotates.

[0065] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
