Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a shake-proof shaker and centrifuge tube holder. Background Technology

[0002] Shaking flasks are mainly used for microbial culture, cell culture and fermentation experiments. Shaking promotes full contact between the culture medium and oxygen, increases the dissolved oxygen supply, and accelerates the reproduction of bacteria or cells. Centrifuge tubes are mainly used for sample separation in biochemistry and other fields.

[0003] Patent CN219898237U discloses a fixed centrifuge tube rack, including a centrifuge tube rack fixing plate and a tube rack assembly connected to the fixing plate for placing centrifuge tubes. The tube rack assembly includes an upper plate, a middle plate, and a bottom plate. The upper and middle plates are respectively provided with upper and middle holes. The middle plate is movably connected to the fixing plate to allow the middle plate to move on a plane, thus misaligning the upper and middle holes to fix the centrifuge tubes. A gasket is placed around each hole to effectively prevent the centrifuge tubes from rotating. This design facilitates operation with a batch-type spiral cap centrifuge tube opener. The product has a simple structure, is easy to operate, economical, and has an adjustable hole size to accommodate the different brands of centrifuge tubes.

[0004] However, existing mounting brackets cannot be used simultaneously for shake flasks and centrifuge tubes. During use, a separate mounting bracket is required, which limits the applicability. Moreover, after mounting, the centrifuge tubes or shake flasks may wobble, making them prone to collapse during transport, indicating insufficient stability. Utility Model Content

[0005] The main purpose of this utility model is to provide a shake-proof shake flask and centrifuge tube fixing bracket, which can effectively solve the technical problems of existing fixing brackets in the background art. When using them, they cannot be used for shake flasks and centrifuge tubes at the same time. During use, they need to be configured with independent fixing brackets, which have a small range of applications. Moreover, after fixing, the fixed centrifuge tubes or shake flasks will shake and are prone to collapse during transportation, resulting in insufficient stability.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A shake-resistant flask and centrifuge tube holder includes a base. A threaded post is fixedly installed at the upper center of the base, and a limiting disc is sleeved on the outside of the threaded post. The limiting disc is used to limit the top of the shake flask or centrifuge tube. A knob is threaded to the outside of the threaded post. Several limiting heads are fixedly installed on the top of the limiting disc. Several limiting grooves are opened on the upper surface of the base, and a support post is fixedly installed at the center of each limiting groove on the bottom of the base. A slot is provided between the support post and the limiting groove.

[0007] As a further embodiment of this utility model, the limiting head is cone-shaped and is used to fit over the top of a shake flask or centrifuge tube to limit movement and prevent shaking.

[0008] As a further embodiment of this utility model, the upper surface of the limiting disc is provided with several through holes, and the bottom of the limiting head is provided with a pressing groove, with the through holes and the pressing groove communicating with each other.

[0009] As a further embodiment of this utility model, the top of the threaded column is threadedly connected to a handle bracket, which is T-shaped and used to move the entire fixed frame.

[0010] As a further embodiment of this utility model, the inner walls of both the limiting head and the support column are provided with rubber pads for buffering and shock absorption.

[0011] As a further embodiment of this utility model, a sleeve post is fixedly installed at the center of the limiting disk. The sleeve post is fitted over the threaded post to increase the contact surface and improve stability.

[0012] The beneficial effects of this utility model are as follows: By setting limit grooves, slots, and pressure grooves, the fixing frame can be adapted to shake flasks or centrifuge tubes, making it widely applicable. In use, there is no need to prepare a specific fixing frame for shake flasks or centrifuge tubes. Moreover, the height-adjustable limiting plate can be set to accommodate shake flasks or centrifuge tubes of different heights, further improving the applicability of the entire fixing frame. It can also prevent shake flasks or centrifuge tubes from shaking, ensuring stability during transportation and avoiding falling and damage. Attached Figure Description

[0016] Example 1 Combination Figures 1-6 A shake-proof flask and centrifuge tube holder includes a base 1. A threaded post 3 is fixedly installed at the upper center of the base 1, and a limiting plate 2 is sleeved on the outside of the threaded post 3. The limiting plate 2 is used to limit the top of the shake flask or centrifuge tube. A knob 5 is threadedly connected to the outside of the threaded post 3. Several limiting heads 6 are fixedly installed on the top of the limiting plate 2. Several limiting grooves 7 are opened on the upper surface of the base 1, and a support post 8 is fixedly installed at the center of each limiting groove 7 at the bottom of the base 1. A slot 9 is provided between the support post 8 and the limiting groove 7.

[0017] See Figure 1 , Figure 2 , Figure 3 and Figure 5 Furthermore, the limiting head 6 is cone-shaped and is used to fit on the top of the shake flask or centrifuge tube to limit movement and prevent shaking. The upper surface of the limiting disk 2 has several through holes, and the bottom of the limiting head 6 has a pressure groove 10. The through holes are connected to the pressure groove 10. The inner walls of the limiting head 6 and the support column 8 are provided with rubber pads for buffering and shock absorption.

[0018] Specifically, first ensure that the distance between the base 1 and the limiting plate 2 is greater than the height of the shake bottle or centrifuge tube, then place the shake bottle or centrifuge tube into the limiting groove 7 or slot 9, then slide the limiting plate 2 downward through the threaded post 3 so that the pressing groove 10 presses on the top of the shake bottle or centrifuge tube, and finally rotate the knob 5 so that the knob 5 presses the position of the limiting plate 2, thereby fixing the shake bottle or centrifuge tube.

[0019] Example 2 See Figure 2 Furthermore, based on Embodiment 1, the top of the threaded column 3 is threadedly connected to a handle 4, which is T-shaped and used to move the entire fixed frame. A sleeve column is fixedly installed at the center of the limiting disc 2, which is sleeved on the outside of the threaded column 3 to increase the contact surface and improve stability.

[0020] Specifically, during transport, the entire fixed frame can be moved by hand using the handle 4, and the shaker or centrifuge tubes are restrained by the limiting plate 2 to prevent them from shaking, ensuring stability during transport.

[0021] It should be noted that this utility model is a shake-proof shake flask and centrifuge tube fixing bracket. When using it, when it is necessary to place the shake flask, first ensure that the distance between the base 1 and the limiting plate 2 is greater than the height of the shake flask, then place the shake flask into the inside of the limiting groove 7, then slide the limiting plate 2 downward through the threaded post 3 so that the pressing groove 10 presses on the top of the shake flask, and finally rotate the knob 5 so that the knob 5 presses the position of the limiting plate 2, thereby fixing the shake flask. When centrifuge tubes need to be placed, ensure that the distance between the base 1 and the limiting plate 2 is greater than the height of the centrifuge tubes. Then place the centrifuge tubes into the slot 9. Next, slide the limiting plate 2 downwards through the threaded post 3 so that the pressure groove 10 presses on the top of the centrifuge tubes. Finally, turn the knob 5 to press the limiting plate 2 into place, thereby fixing the centrifuge tubes. After fixing, the entire fixing frame can be moved by the handle 4.
