Description

Technical Field

[0001] This utility model belongs to the field of oscillator support technology, specifically relating to an oscillator fixing support for sample mixing. Background Technology

[0002] Sample mixing shaker holders are commonly used in laboratories, especially when samples need to be shaken and mixed or cultured. They are designed to hold sample containers (such as test tubes, bottles, or petri dishes) in place on the shaker, ensuring that the containers do not move during shaking and thus ensuring uniform mixing.

[0003] When existing sample tubes are shaken using a shaker, they do not have a fixed support and require manual assistance to shake and mix evenly. This can easily cause the sample tubes to shift, resulting in insufficient mixing. Moreover, shaking a batch of sample tubes will increase the time cost of manual labor.

[0004] Therefore, this utility model provides a sample mixing oscillator fixing bracket. Utility Model Content

[0005] The purpose of this invention is to provide a sample mixing oscillator fixing bracket that can solve the problems mentioned in the background art.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A sample mixing oscillator fixing bracket includes a lower screen frame and a upper screen frame. Four support rods are arranged in a circular array between the lower screen frame and the upper screen frame. The upper screen frame is fixed above the lower screen frame by the support rods.

[0008] Both the lower grid and the upper grid are provided with limiting grids, and the two limiting grids correspond to each other;

[0009] The bottom of the lower grid frame has four brackets arranged in a circular array for mounting support.

[0010] This utility model is further configured such that the lower mesh frame, the upper mesh frame, and the support rod are all made of metal and are welded together.

[0011] The present invention is further configured such that: a screw is provided at the top of the bracket, and multiple internal threaded holes are machined in a circumferential array at the lower end of the lower mesh frame, and the bracket is screwed into the internal threaded holes at the bottom of the lower mesh frame by the screw at its top.

[0012] The present invention is further configured such that a curved section is provided in the middle of the bracket.

[0013] The present invention is further configured such that the limiting grid includes multiple transverse metal wires and longitudinal metal wires, and the transverse metal wires and longitudinal metal wires are distributed in a crisscross pattern.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This utility model discloses a sample mixing oscillator fixing bracket, which adopts a double-layer limiting grid design and has a certain degree of expansion and recovery. It can not only limit and fix the sample tube to replace the traditional method of manually assisting the sample tube to shake, thus avoiding the problem of insufficient sample mixing due to sample tube displacement, but also can be used to limit sample tubes of different sizes, making it more versatile and easier to install. This design can reduce labor and time costs, and can also ensure that the sample is fully mixed, thereby improving data accuracy. Attached Figure Description

[0024] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-7As shown, a sample mixing shaker fixing bracket includes a lower mesh frame 1 and a top mesh frame 3. Four support rods 4 are arranged in a circular array between the lower mesh frame 1 and the top mesh frame 3. The top mesh frame 3 is fixed directly above the lower mesh frame 1 by the support rods 4. The lower mesh frame 1, the top mesh frame 3, and the support rods 4 are all made of metal and are welded together. The double-layer mesh frame (i.e., the lower mesh frame 1 and the top mesh frame 3) design can improve the stability of the test tubes, ensure that the sample tubes are mixed evenly by shaking, and avoid the sample tubes from shifting during shaking, which would affect the incomplete mixing of the samples.

[0026] Both the lower wire mesh frame 1 and the upper wire mesh frame 3 are equipped with limiting grids 5, and the two limiting grids 5 correspond to each other (e.g., Figure 5 As shown), the grids are arranged in a corresponding manner to ensure that sample tubes are inserted into the same grid without tilting. The limiting grid 5 includes multiple horizontal and vertical metal wires, which are crisscrossed. The ends of the horizontal and vertical metal wires are fixed to the grid frame (i.e., the lower grid frame 1 and the upper grid frame 3), respectively. The intersection points of the horizontal and vertical metal wires are not connected. This allows the horizontal and vertical metal wires to expand to accommodate test tubes of different diameters. Furthermore, when a large-diameter test tube expands, the grid provides a reaction force to limit the test tube, further improving the limiting and fixing of the test tube (e.g., ...). Figure 7 As shown), in addition, since its two ends are straightened and fixed, the transverse and longitudinal metal wires can be quickly reset after the test tube (i.e. the sample tube) is taken out. It should be noted that the limiting grid 5 of this design is not limited to metal grids, but can also use other grid materials with certain expansion and recovery properties, such as polyester grids or elastic fiber grids.

[0027] The bottom of the lower mesh frame 1 has four brackets 2 arranged in a circular array for mounting support. Each bracket 2 has a screw 22 at its top. The lower end of the lower mesh frame 1 has multiple internally threaded holes 23 machined in a circular array (e.g., ...). Figure 6 As shown, the bracket 2 is screwed into the internal threaded hole 23 at the bottom of the lower mesh frame 1 by the screw 22 at its top. The bracket 2 is designed to be detachable. The purpose is to facilitate the vibration of test tubes of different lengths. The bracket 2 of the corresponding length can be selected according to the length of the test tube to ensure that when the test tube is placed in the mesh frame, the top of the test tube is above the mesh frame 3, which is convenient for the test tube to be put in and taken out. For example, when the test tube is short, if the bracket 2 is of a longer size, the top of the test tube may be between the mesh frame 3 and the lower mesh frame 1 when the test tube is placed on the mesh frame. This will make it inconvenient to take out the test tube. Therefore, by selecting the bracket 2 of the corresponding length, it is possible to fix test tubes of different lengths for vibration.

[0028] like Figure 3 and 4As shown, the middle part of the support 2 is also provided with a curved section 21. The difference between supports 2 of different lengths lies in the different lengths of the upper half (i.e., between the screw 22 and the curved section 21). When the mesh frame is fixed to the sample tube oscillator, the curved section 21 of the support 2 is used to directly clamp onto the edge of the oscillator tray, as shown. Figure 7 As shown, this allows the curved segment 21 to be positioned on the tray (i.e., Figure 7 a) A snap-fit ​​is formed at the edge to support the grid frame. It should be added that the fixed bracket of this design is not limited to installation on a circular pallet. It can also be assembled on the internal threaded holes 23 at different positions of the lower grid frame 1 to realize the position arrangement of the bracket 2, so as to facilitate its fixation on other types of pallets, such as rectangular pallets.

[0029] The working principle of this utility model is as follows: Before use, the corresponding support 2 can be selected according to the length of the test tube, and its threads can be screwed onto the lower mesh frame 1. Then, the curved section 21 in the middle of the support 2 can be used to lock it onto the tray of the shaker.

[0030] In use, the sample tube to be shaken is inserted from the limiting grid 5 on the wire mesh frame 3 into the limiting grid 5 on the lower wire mesh frame 1. The double-layer limiting grid 5 is used to limit and fix the sample tube, replacing the traditional method that requires manual assistance to shake the sample tube. This avoids the sample tube from shifting and affecting the insufficient mixing of the sample. This design can reduce time and labor costs and ensure that the sample is fully mixed, thereby improving the accuracy of the data.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
