Description

Technical Field

[0001] This utility model relates to a centrifuge tube rack. Background Technology

[0002] To facilitate use and improve the simplicity and convenience of the operating environment, there is a need for centrifuge tube racks that can flexibly accommodate various sizes of centrifuge tubes. For example, the invention patent application CN111495460 A discloses an adjustable-aperture centrifuge tube rack, which mainly uses the coordinated positions of staggered fixed and movable plates to accommodate centrifuge tubes of various sizes. The utility model patent CN221360010 U discloses a centrifuge tube rack that mainly achieves the placement of centrifuge tubes of various sizes through the assembly of multiple connecting parts of different tube diameters in a stacked and assembled manner. However, both of these technical solutions require pre-assembly based on the centrifuge tube sizes to be used. After pre-setting, the compatible centrifuge tube sizes are determined. When using new centrifuge tube sizes, a new setup is required. Obviously, they cannot adapt to the needs of more centrifuge tube sizes. Furthermore, as can be seen from the accompanying drawings, their structures are relatively complex and require operators with corresponding skills and proficiency. Utility Model Content

[0005] Furthermore, a lantern spring is fitted over the conical body, and a second notch is opened at the top of the lantern spring.

[0006] Furthermore, a compression and reset component is provided on the outer sleeve of the conical body. The compression and reset component includes at least three spring rings arranged sequentially along the axial direction and left and right spring rings symmetrically arranged at the radial outer ends of the spring rings. An intermediate spring ring is also provided at the radial outer end of the spring ring at the middle position of the left and right spring rings.

[0007] A third notch is provided on the spring ring directly opposite the middle spring piece.

[0008] Furthermore, a tower spring is fitted over the compression reset component. This tower spring is made of coiled spring sheets, with its large diameter end facing upwards.

[0009] Further, the outer edge of the top ring of the cone is provided with a plug for inserting into the socket provided on the shelf plate.

[0010] The centrifugal tube inserting and placing part of the utility model has the advantages of simple structure, convenient operation, adaptability to centrifugal tubes of various specifications and realization of close and stable clamping of the centrifugal tubes. BRIEF DESCRIPTION OF DRAWINGS

[0019] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined purpose, the specific implementation, structural features and effects of the utility model will be described in detail as follows in combination with the drawings and examples.

[0020] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] The terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features; in the description of the utility model, unless otherwise stated, the meaning of "multiple" is two or more.

[0023] Figure 1 As shown is a kind of centrifugal tube rack, including centrifugal tube insert piece, special in that, the centrifugal tube insert piece is open conical tube, first gap 2 (i.e. form the opening of conical tube, so it is called open conical tube) is set on the taper body 1 and extends to the bottom in the axial direction;The setting of the first gap 2 makes the left collar part 3 and right collar part 4 on its two sides overlap radially and can be rolled up or unfolded along the circumference. By the open conical tube as centrifugal tube insert piece, that is, as long as the maximum diameter of centrifugal tube does not exceed the diameter of the maximum diameter section of designed open conical tube, such as the maximum diameter section of open conical tube, i.e. the maximum diameter of its opening top can accommodate the insertion of 50ml centrifugal tube, then other centrifugal tubes smaller than 50ml can be inserted into the open conical tube, and at the beginning, the left collar part 3 and right collar part 4 of open conical tube overlap each other so that the open conical tube is in the state of rolling up, when the centrifugal tube is inserted into it, it will actively extrude the inner wall of open conical tube with the extension of the diameter of inserted centrifugal tube, so that the left collar part 3 and right collar part 4 slide away from each other, and keep close contact with the inserted centrifugal tube during the process of moving away. In this way, it can not only adapt to the size of the tube diameter of inserted centrifugal tube to accommodate the centrifugal tube, but also can tightly hold the inserted centrifugal tube, ensuring the stability of the inserted centrifugal tube and preventing it from falling due to accidental collision or vibration. Especially when the open conical tube is made of elastic material, it can not only adapt to various specifications of centrifugal tubes smaller than the maximum designed tube diameter through its passive unfolding and active rolling characteristics, but also can always stably hold the inserted centrifugal tube.

[0024] In order to further improve the active rolling of open conical tube, the embodiment is characterized in that Figure 2The lantern spring is shown, and a second gap 5 is opened at the top of the lantern spring to cooperate with the first gap 2 on the open conical tube, to adapt to the expansion of the inserted centrifugal tube when extruded, so as to accommodate the inserted centrifugal tube.

[0025] Similarly, in order to further improve the active winding of the open conical tube and meet its passive expansion, the embodiment is provided with a Figure 3 The shown tight reset part includes at least three spring rings 6 arranged in sequence along the axial direction, and left and right spring sheets 7 and 8 symmetrically arranged at the radial outer end of the spring ring 6, and the radial outer end of the spring ring 6 at the middle position of the left and right spring sheets 7 and 8 is further provided with a middle spring sheet 9, and the third gap 10 is provided on the spring ring 6 opposite to the middle spring sheet 9. Through the spring ring 6, the left and right spring sheets 7 and 8 and the middle spring sheet 9, the elastic extrusion of the conical body 1 can be realized, so that it is in the state of shrinking or winding, and at the same time, the stability of the close clamping of the inserted centrifugal tube is further improved. And with the help of the third gap 10 provided on the spring ring 6, the passive expansion of the conical body 1 is not limited.

[0026] The tight reset part is provided with a Figure 4 The shown tower spring is wound by spring sheets, and the large diameter end is arranged upward, that is, the arrangement mode is consistent with that of the conical body 1, so that the force deformation, the change of the space size of the two are consistent, and the embodiment can effectively limit the maximum value of the deformation diameter of the conical body 1 through the tower spring, to avoid excessive deformation to damage the tension of the conical body 1, otherwise, when the tension is damaged, the function of active elastic deformation recovery winding will be reduced when the external force is removed.

[0027] The outer edge of the top ring opening of the conical body 1 is provided with a plug 11 for insertion into Figure 6 The shown hole in the shelf plate 12.

[0028] Finally, by Figure 6 It can be seen that in specific application, the conical body 1 provided by each of the above embodiments is uniformly inserted into the hole on the shelf plate 12, and the conical body 1 is hooked by the plug 11 and the hole on the shelf plate 12, and according to the needs, the lantern spring or the tight reset part or even the tower spring can be selected to be sleeved outside the conical body 1, so that it meets the design needs, but no matter which combination is selected, it can meet the insertion of each specification of centrifugal tube smaller than the maximum tube diameter, and only the traditional way of inserting the centrifugal tube into the conical body 1 is needed, the conical body 1 is extruded and deformed by the insertion force of the centrifugal tube, and it is self-adaptive to the diameter of the centrifugal tube, without any other adjustment, it can meet the insertion of different specifications of centrifugal tube in the design range, and at the same time, it can realize the close and stable clamping of the centrifugal tube.
