Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of laboratory equipment, especially to a precooling ice box suitable for multiple tube types. BACKGROUND

[0002] In the experimental field of molecular biology, biochemistry and cell biology, low-temperature environment is crucial for the preservation and processing of experimental samples and reagents. In the experimental process, precooling modules are often used to provide low-temperature environment for experimental samples and reagents. However, most of the precooling modules on the market have a single structure design, poor flexibility and low space utilization efficiency. Most precooling modules are simple blocks or plates, which are difficult to flexibly combine according to actual experimental needs, especially in the case of limited laboratory space. Such modules will occupy a large amount of valuable space and are inconvenient to store. For example, when the number and type of experimental samples are variable, traditional precooling modules cannot quickly adapt, and multiple specifications of modules need to be equipped, which greatly increases the cost and management difficulty. Many precooling modules have a single tube hole specification, which cannot meet the precooling needs of multiple specifications of experimental tubes commonly used in laboratories (such as EP tubes, centrifugal tubes, PCR tubes, etc.), resulting in the need for multiple different precooling devices during the experimental process, which is cumbersome to operate and easy to confuse samples. In addition, some precooling modules perform poorly in stability and lack effective anti-slip measures, which are easily displaced due to accidental collision or slight vibration during experimental operation, affecting the experimental process and even causing experimental accidents.

[0003] Therefore, there is an urgent need for a precooling ice box with reasonable structure design, safety and reliability, and convenient operation to meet the growing experimental needs.

[0004] Therefore, it is necessary to design a precooling ice box suitable for multiple tube types to solve the above problems. INVENTION CONTENTS

[0027] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be described in detail below with reference to the drawings and specific embodiments.

[0028] Here, it also needs to be explained that, in order to avoid the present application from being obscured by unnecessary details, only the structures and / or processing steps closely related to the scheme of the present application are shown in the drawings, and other details not closely related to the present application are omitted.

[0029] In addition, it also needs to be explained that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or includes elements inherent to such process, method, article or equipment.

[0030] Please refer to Figs. 1-3 As shown in the drawings, the present application provides a pre-cooling ice box suitable for multiple pipe types, which comprises:

[0031] The box body 10 is hollow inside, and a plurality of pipe holes 20 are arranged on at least three faces of the box body 10, and a plurality of anti-skid blocks 12 are further arranged on the box body 10.

[0032] The limiting ring 30 is arranged on the side of the pipe hole 20 close to the center of the box body 10, and the diameter of the limiting ring 30 gradually increases along the direction close to the center of the box body 10.

[0033] Exemplarily, the box body 10 is a cuboid structure, and a plurality of tube holes 20 are arranged on each face of the box body 10. Exemplarily, the tube holes 20 on the same face of the box body 10 have the same hole diameter, and the box body 10 has five types of tube holes 20 with different diameters, including 0.2ml PCR tube holes, 1.5ml EP tube holes, 2ml EP tube holes, 10ml centrifuge tube holes and 50ml centrifuge tube holes. The 0.2ml PCR tube holes are arranged on the top face and the bottom face of the box body 10, the 1.5ml EP tube holes and the 2ml EP tube holes are arranged on the opposite two side faces of the box body 10 respectively, and the 10ml centrifuge tube holes and the 50ml centrifuge tube holes are arranged on the other two opposite side faces of the box body 10 respectively.

[0034] Exemplarily, the hole diameters of the 1.5ml EP tube holes and the 2ml EP tube holes and the center-to-center distances of the tube holes 20 are the same, that is, the 1.5ml EP tube holes and the 2ml EP tube holes on the opposite two faces are correspondingly arranged on the side faces of the box body 10.

[0035] Exemplarily, the 50ml centrifuge tube hole is arranged at the center of one face, and four 10ml centrifuge tube holes are arranged on the opposite face, and the four 10ml centrifuge tube holes are arranged around the 50ml centrifuge tube hole, so that the two types of centrifuge tubes are inserted into each other in the box body without affecting each other.

[0036] By appropriately adjusting the distribution of the tube holes 20 on each face, the five faces except the bottom face can store tube bodies when the bottom face of the box body 10 is placed on the storage room placement plane, thereby improving the space utilization rate of the pre-cooling ice box.

[0037] Specifically, a plurality of anti-skid blocks 12 are arranged on each face of the box body 10, so that the pre-cooling ice box can be stably placed on the storage room or the experimental table, and the pre-cooling ice box is prevented from sliding. In the example, the anti-skid blocks 12 are hemispherical, and the anti-skid blocks 12 are arranged at the four corners of each face. In other examples, the anti-skid blocks 12 can also be arranged in other shapes such as circular truncated cone, as long as the anti-skid effect can be achieved. The material of the anti-skid blocks 12 is rubber.

[0038] Specifically, a chamfer 21 for reducing friction is arranged at the hole of the tube hole 20. By arranging the chamfer 21, damage to the tube body and the sample in the tube body during plugging and unplugging can be prevented.

[0039] Specifically, the acute angle formed by the side wall of the limiting ring 30 and the axial direction thereof is equal to the angle of the chamfer 21. Exemplarily, the acute angle formed by the side wall of the limiting ring 30 and the axial direction thereof is 10-30°. The setting of the limiting ring 30 can enable the tube body to present a slanting downward posture along the direction close to the center of the box body 10 when the tube body is inserted on the box body 10 through the side surface during storage, so that the tube body located on the side surface of the hollow multi-surface structure can be stably placed in the tube hole 20. Compared with the tube body in a horizontal posture placed in the tube hole 20 on the side surface of the box body 10, the tube body in a slanting downward posture can avoid being easily slipped out of the box body 10 due to accidental collision or slight vibration. In addition, the setting that the diameter of the limiting ring 30 gradually increases along the side close to the center of the box body 10 enables the tube body to present a slanting downward posture along the direction close to the center of the box body 10 when the corresponding tube body is placed on the tube hole 20 on the side surface of the box body 10, regardless of which side of the box body 10 is downward, that is, 0.2ml PCR tube hole, 1.5ml EP tube hole, 2ml EP tube hole, 10ml centrifuge tube hole or 50ml centrifuge tube hole.

[0040] As shown in Fig. 3 the limiting ring 30 and the chamfer 21 can form a certain limiting space, that is, when the tube body is placed in the tube hole 20 in a slanting downward posture, the bottom surface of the tube body abuts against the limiting ring 30, and the top surface of the tube body abuts against the chamfer 21. This abutting mode enables the tube body to be placed in the tube hole 20 in a relatively stable state, and the slanting downward posture can reduce the probability of the tube body being slipped out of the tube hole 20 under external force. Fig. 3 In the specific embodiment, only the structure of a single tube hole 20 on each side of the box body 10 is shown.

[0041] Specifically, the box body 10 is further provided with a rounded corner 11 at each edge of the outer periphery, so that a smooth transition curved surface is formed at each edge of the box body 10.

[0042] Specifically, the box body 10 is further provided with a phase change material filling area. Exemplarily, the phase change material filling area includes a first filling area 41 arranged around the inner side of the box body 10 and a second filling area 42 arranged at the four corners inside the box body 10, and the filling areas are filled with phase change material. The setting of the phase change material filling area can increase the pre-cooling effect of the box body 10. As to the position of the phase change material filling area, the embodiment is only exemplary, and the phase change material filling area can be set on the box body 10 according to actual conditions without affecting the insertion and removal of the tube body, and the thickness of the first filling area 41 can also be set as needed. Exemplarily, the phase change material is gel.

[0043] Specifically, the material of the box body 10 is aluminum, and the frame of the phase change material filling area is also made of aluminum, so that the box body 10 has the characteristics of lightness and high thermal conductivity, so that the pre-cooling ice box can realize rapid pre-cooling and efficient heat exchange, so that the sample in the pipe body can quickly reach a low temperature state, which is beneficial to maintain the activity of the sample and the accuracy of the experiment. The lightness of the pre-cooling ice box also improves the efficiency of the experimental operation. In addition, the surface of the pre-cooling ice box is also easy to generate an aluminum oxide film. Since the aluminum oxide film is corrosion-resistant and can resist water vapor and reagent erosion, the pre-cooling ice box can have a longer service life and effectively reduce the use cost.

[0044] Compared with the traditional aluminum pre-cooling ice table, the pre-cooling ice box has a magic way of cuboid structure design, which solves the problems of low space utilization, many safety hazards, poor stability, single pipe hole 20 adaptation and the like. The magic way design, edge treatment, anti-skid block 12 arrangement and various specifications of pipe hole 20 setting improve the practicability, safety and functionality of the pre-cooling ice box.

[0045] The above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
