Description

Technical Field

[0001] This utility model relates to the field of linear shaking table technology, and in particular to a fixing mechanism for easy positioning of a linear shaking table. Background Technology

[0002] A linear shaker is a highly efficient and stable experimental device that simulates a linear motion environment to provide precisely controllable shaking or oscillation conditions for various experiments. This ingeniously designed and robust device ensures that experimental samples undergo uniform and stable shaking at set frequencies and amplitudes, thus meeting the stringent requirements of experiments in biology, chemistry, and medicine, such as cell culture, chemical reactions, and solution mixing. With its excellent performance and wide applicability, the linear shaker has become an indispensable tool in scientific research laboratories.

[0003] Linear shakers employ various fixation methods, such as test tube clamps, tape, rubber bands, string, test tube racks, or magnets, to ensure the stability of experimental samples during shaking, thereby guaranteeing the accuracy and reliability of experimental results. These flexible fixation methods can adapt to experimental samples of different shapes and sizes, making the linear shaker an indispensable and efficient tool in scientific research experiments.

[0004] When using a linear shaker, it is necessary to fix the sample, and the efficiency and convenience of sample fixation must be ensured. However, considering that fixing the sample with fixing mechanisms such as tape, rubber bands, thin ropes, and test tube racks is not convenient for overall sample fixation, it will greatly reduce the efficiency of sample fixation, affect experimental efficiency, and be extremely inconvenient. Therefore, there is an urgent need for a fixing mechanism for linear shakers that is easy to position, in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fixing mechanism for a linear shaker that is easy to position. This solves the problem that in the prior art, fixing mechanisms such as tape, rubber bands, thin ropes, and test tube racks are not convenient for fixing the sample as a whole, which greatly reduces the efficiency of sample fixing and affects the efficiency of experiments.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fixed mechanism for easy positioning of a linear shaker includes a shaker body, a bearing frame mounted on the top shaking mechanism of the shaker body, a top frame slidably connected to the top of the bearing frame, a cylinder fixedly connected to one side of the top of the top frame by bolts, and clamping plates elastically connected to both sides of the inner side of the bearing frame, with a pressure plate provided at the top between the two clamping plates. The output shaft of the cylinder passes through the top of the top frame and is fixedly connected to the top of the pressure plate. Several buffer pads are fixedly connected to the bottom of the pressure plate.

[0008] Preferably, sliders are fixedly connected to both sides of the top frame, and both sliders are slidably connected to the outer wall of the support frame through a groove.

[0009] Preferably, the connection between the cylinder's output shaft and the top frame is a sliding connection.

[0010] Preferably, the two opposing sides of the clamping plates are elastically connected to the inner wall of the support frame by several compression springs.

[0011] Preferably, sliding blocks are fixedly connected to both sides of the pressure plate, and both sliding blocks are slidably connected to the inner wall of the support frame through sliding grooves.

[0012] Preferably, the top of all the cushioning pads is fixedly connected to a connecting rod, and the top of all the connecting rods is fixedly connected to the bottom of the pressure plate.

[0013] Preferably, each of the two clamping plates has several arc-shaped grooves on its opposite side, and the arc-shaped grooves on the two clamping plates are distributed in a one-to-one correspondence.

[0014] Preferably, a side plate is fixedly connected to one side of the top frame, and a threaded rod is provided on one side of the side plate, and the threaded rod passes through the side plate and the side wall of the load-bearing frame in sequence through the threaded groove.

[0015] This utility model has the following beneficial effects:

[0016] By using a cylinder to drive the pressure plate downwards, combined with the clamping action of the clamping plates, multiple experimental samples can be quickly and stably fixed. Compared with traditional manual fixing methods, this significantly shortens the fixing time and improves experimental efficiency. The synergistic effect of the clamping plates and pressure plates, along with the protective design of the buffer pads, constitutes a robust fixing mechanism. Even during the high-speed shaking of the linear shaker, the experimental samples remain in place, preventing displacement or detachment, thus ensuring the accuracy of the experimental results. The elastic connection design of the clamping plates allows this fixing mechanism to adapt to experimental samples of different shapes and sizes, improving the versatility and flexibility of the linear shaker. Whether it's small test tubes or large containers, effective fixing can be achieved by adjusting the position and force of the clamping plates and pressure plates. The introduction of the buffer pads not only increases the stability of the fixing but also effectively avoids pressure damage to the experimental samples during the fixing process. This is of great significance for protecting valuable or fragile experimental samples. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Reference Figure 1-5. A positioning fixing mechanism for a linear shaker includes a shaker body 1. A support frame 2 is mounted on the top shaking mechanism of the shaker body 1, and a top frame 3 is slidably connected to the top of the support frame 2. The top frame 3 not only provides a mounting position for the cylinder 8, but also facilitates installation and disassembly through its sliding design. Under the action of the cylinder 8, the top frame 3 can be stably held at the top of the support frame 2, providing stable support for the descent of the pressure plate 9. The cylinder 8 is fixedly connected to the top side of the top frame 3 by bolts, and clamping plates 10 are elastically connected to both sides of the inner side of the support frame 2. The clamping plates 10 are key components for the initial fixing of experimental samples. The compression spring 12 is connected to the inner wall of the support frame 2, and can be adaptively adjusted according to the shape and size of the experimental sample to achieve initial clamping and fixing of the sample. This design not only improves the adaptability of the fixing mechanism, but also prevents the sample from shifting or falling off during shaking. Furthermore, a pressure plate 9 is provided at the top between the two clamping plates 10. The output shaft of the cylinder 8 passes through the top of the top frame 3 and is fixedly connected to the top of the pressure plate 9. Several buffer pads 13 are fixedly connected to the bottom of the pressure plate 9. The buffer pads 13 are important components that protect the experimental sample from pressure damage. They can evenly distribute the pressure applied by the pressure plate 9, and at the same time absorb some vibration and impact, ensuring that the sample remains intact during shaking.

[0026] Furthermore, sliders 4 are fixedly connected to both sides of the top frame 3, and both sliders 4 are slidably connected to the outer wall of the support frame 2 through the sliding groove 5. This not only facilitates the installation and disassembly of the top frame 3, but also ensures that the top frame 3 can be stably held on the top of the support frame 2 when the pressure plate 9 is lowered by the cylinder 8. This ensures the stability and accuracy of the fixing mechanism and achieves the effect of improving the ease of operation and fixing stability.

[0027] Furthermore, the connection between the output shaft of cylinder 8 and the top frame 3 is a sliding connection.

[0028] Furthermore, the two clamping plates 10 are elastically connected to the inner wall of the bearing frame 2 on opposite sides by several compression springs 12. The clamping plates 10 can be adaptively adjusted according to the shape and size of the experimental sample to achieve initial clamping and fixing of the sample. The elastic force of the compression springs 12 allows the clamping plates 10 to fit tightly against the sample while maintaining a certain degree of flexibility to avoid damage to the sample, thus improving the adaptability of the fixing mechanism and protecting the experimental sample.

[0029] Furthermore, sliding blocks 15 are fixedly connected to both sides of the pressure plate 9, and both sliding blocks 15 are slidably connected to the inner wall of the support frame 2 through the sliding groove 14. Under the drive of the cylinder 8, the pressure plate 9 can descend stably along the inner wall of the support frame 2, ensuring that the pressure plate 9 will not deviate from the predetermined trajectory during the descent, so as to accurately contact the top of the experimental sample and apply pressure, thereby achieving the effect of improving the fixing accuracy and stability.

[0030] Furthermore, all the tops of the buffer pads 13 are fixedly connected to the connecting rods 16, and the tops of all the connecting rods 16 are fixedly connected to the bottom of the pressure plate 9. The buffer pads 13 can evenly distribute the pressure applied by the pressure plate 9, while absorbing some vibration and impact, protecting the experimental samples from damage. The rigid connection of the connecting rods 16 ensures the stable relationship between the buffer pads 13 and the pressure plate 9, thereby improving the protective performance and stability of the fixing mechanism.

[0031] Furthermore, several arc-shaped grooves 11 are provided on the opposite side of each of the two clamping plates 10, and the arc-shaped grooves 11 on the two clamping plates 10 are distributed in a one-to-one correspondence. The clamping plates 10 can better adapt to the shape of the experimental sample. Especially for samples with curved surfaces or irregular shapes, the design of the arc-shaped grooves 11 increases the contact area between the clamping plates 10 and the sample, improves the clamping force, and achieves the effect of improving the adaptability and fixing effect of the fixing mechanism to irregularly shaped samples.

[0032] Furthermore, a side plate 6 is fixedly connected to one side of the top frame 3, and a threaded rod 7 is provided on one side of the side plate 6. The threaded rod 7 passes through the side plate 6 and the side wall of the bearing frame 2 in sequence through the threaded groove. The threaded rod 7 passes through the side plate 6 and the side wall of the bearing frame 2 in sequence through the threaded groove, thereby realizing the limiting and fixing of the top frame 3, ensuring that the top frame 3 will not loosen or fall off during shaking, thus ensuring the stability and safety of the fixing mechanism, and achieving the effect of improving the overall stability and reliability of the fixing mechanism.

[0033] In summary:

[0034] In the workflow, firstly, the shaker body 1 of the linear shaker (model DLAB) is prepared, with a support frame 2 already installed on its top shaking mechanism. Next, the experimental sample to be fixed is placed inside the support frame 2. At this time, the clamping plates 10, which are elastically connected on both sides of the inner side of the support frame 2 and connected to the inner wall of the support frame 2 by compression springs 12, will make appropriate adaptive adjustments according to the shape and size of the experimental sample, thus initially clamping and fixing the sample. The arc-shaped grooves 11 on the clamping plates 10 increase the contact area with the sample and improve the clamping force, which is particularly suitable for samples with curved or irregular shapes. Subsequently, the top frame 3 is slidably connected to the sliding grooves 5 on the outer wall of the support frame 2 by the sliders 4 fixedly connected on both sides, so that the top frame 3 is stably placed on top of the support frame 2. Then, the threaded rods 7 on the side plates 6 fixedly connected to one side of the top frame 3 pass through the threaded grooves in sequence through the side plates 6 and the side walls of the support frame 2 to limit and fix the top frame 3, ensuring that the top frame 3 will not loosen or fall off in subsequent operations. Next, cylinder 8 is operated. The output shaft of cylinder 8 extends downward, passing through the top of the top frame 3 and being fixedly connected to the top of the pressure plate 9. Under the driving force of cylinder 8, the pressure plate 9 slowly descends. At the same time, the sliding blocks 15 on both sides of the pressure plate 9 slide steadily down along the sliding grooves 14 on the inner wall of the support frame 2, ensuring that the pressure plate 9 does not deviate from the predetermined trajectory during descent. When the pressure plate 9 descends to the point where the buffer pad 13 at its bottom is tightly attached to the top of the experimental sample, cylinder 8 stops driving. The buffer pad 13 can not only evenly distribute the pressure applied by the pressure plate 9, but also absorb some vibration and impact, effectively protecting the experimental sample from pressure damage. Thus, the clamping plate 10 and the pressure plate 9 work together to form a stable fixing mechanism, ensuring the stability and safety of the experimental sample during shaking. When the linear shaker body 1 is started, and the top shaking mechanism drives the support frame 2 and the experimental sample inside to shake linearly, this fixing mechanism can firmly fix the sample, preventing it from shifting or falling off, thereby ensuring the accuracy and reliability of the experiment.
