Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically a novel magnetic frame. Background Technology

[0002] Currently, the magnetic rack fixing design on the market has relatively high requirements for the EP tubes, centrifuge tubes and other materials used in the specific operation of the experiment. It is necessary to purchase and use the appropriate diameter. Otherwise, it will be more difficult to adsorb and pick up the tubes when the diameter is slightly larger, while it will be difficult to fix them when the diameter is slightly smaller. Both of these situations can easily cause some pollution and increase the cost of use.

[0003] The existing patent document CN 207786800 U provides a novel magnetic frame with a simple overall structure, easy processing, low cost, and the ability to generate strong magnetic force without the need for high-quality magnets.

[0004] However, the existing ones cannot adjust the diameter during use, which increases the cost of use. Utility Model Content

[0006] The purpose of this invention is to provide a novel magnetic frame to solve the problem mentioned in the background art of the inability to adjust the size of the existing aperture.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a novel magnetic frame, comprising a main body and an adjustment mechanism, wherein the adjustment mechanism is fixedly installed inside the main body, the main body includes a magnetic frame, a frame, and a base, the frame is fixedly installed at the top of the magnetic frame, and the base is fixedly installed at the bottom of the magnetic frame;

[0009] The adjustment mechanism includes a linkage knob, a single-row knob, and adjustment holes. The linkage knob is fixedly installed on the side of the magnetic frame, and several single-row knobs are fixedly installed on the top of the frame. Several adjustment holes are fixedly installed on the surface of the frame, and each single-row knob corresponds to one adjustment hole.

[0010] Furthermore, the main body also includes placement holes and magnets. Several placement holes are fixedly installed on the surface of the base, and magnets are fixedly installed at the bottom of the placement holes inside the base.

[0011] Furthermore, the adjustment mechanism also includes a gear and a rack, with the linkage knob fixedly mounted with a gear and the gear fixedly connected to a rack.

[0012] Furthermore, the adjustment mechanism also includes a connecting rod and a sliding block, the rack is fixedly connected to the connecting rod of each adjustment hole, and the connecting rod is fixedly mounted with the sliding block.

[0013] Furthermore, the main structure also includes a column and a limiting groove. The column is fixedly installed between the frame and the base, and the sliding block is fixedly installed with the limiting groove.

[0014] Furthermore, the adjustment mechanism also includes a screw and a clamping plate, the single-row knob is fixedly mounted with the screw, and the screw is fixedly connected to the clamping plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Highly efficient sample separation: For magnetic particles in biological samples or chemical solutions, the new magnetic rack provides a strong and uniform magnetic field. This uniform magnetic field ensures that magnetic materials are quickly and accurately adsorbed onto the walls or bottom of the rack. For example, when separating magnetically labeled cells from complex biological samples, the new magnetic rack can complete the separation in a shorter time compared to traditional methods, greatly improving experimental efficiency. 2. Improved sample purity: Due to its precise magnetic field design, the new magnetic rack effectively avoids the adsorption of non-magnetic impurities. In chemical synthesis experiments, when it is necessary to separate magnetic catalysts, it can adsorb only the catalyst particles without adsorbing other non-magnetic byproducts in the solution, thereby improving the purity of the recovered catalyst, facilitating catalyst reuse, and providing a purer sample for subsequent chemical analysis. 3. Flexible sample handling capacity: Some new magnetic racks have adjustable structures or different sizes. This allows them to adapt to sample handling needs of different volumes. For example, in processing small-volume gene sequencing samples (e.g., a few microliters) and large-scale protein purification, suitable magnetic rack models can be found, or the parameters of the magnetic rack can be adjusted to meet experimental requirements. Compared to traditional methods that may require vigorous centrifugation or the addition of chemical reagents for separation, novel magnetic racks rely on magnetic fields, causing less interference with the physical and chemical environment of the sample. For some environmentally sensitive biological samples, such as active enzymes, antibodies, or microorganisms, using magnetic racks to separate magnetically labeled target substances can better maintain their activity, thereby ensuring the accuracy of experimental results.

[0017] 2. Improved Production Efficiency: In the processing of magnetic materials, the new magnetic rack can be used for rapid screening and separation of materials with different magnetic strengths. For example, in the production of high-performance permanent magnet materials, qualified magnetic materials can be quickly separated from mixed raw materials, reducing the time and workload of manual screening. If manual screening of each kilogram of material previously took one hour, using the new magnetic rack may only take 10 minutes, greatly improving the production cycle. Reduced Production Costs: Because the new magnetic rack can efficiently separate and recover magnetic materials, material waste is reduced. In some chemical production processes involving expensive magnetic catalysts, the precise magnetic adsorption recovery of catalysts significantly increases the catalyst recovery rate (potentially from 70% to over 90%), reducing raw material procurement costs. Simultaneously, the efficient separation process also reduces equipment operating time and energy consumption, indirectly lowering production costs. Improved Product Quality: In the electronics industry, for the production of high-precision magnetic sensors and other products, the new magnetic rack ensures precise positioning and high-quality assembly of magnetic components during the production process. For example, when mounting tiny magnetic chips onto a circuit board, the precise magnetic field control of the magnetic rack can accurately attract the chips to the designated position, ensuring the performance and quality stability of the product and reducing the defect rate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a novel magnetic frame, including a main body 1 and an adjustment mechanism 2. The adjustment mechanism 2 is fixedly installed inside the main body 1. The main body 1 includes a magnetic frame 101, a frame 102, and a base 103. The frame 102 is fixedly installed at the top of the magnetic frame 101, and the base 103 is fixedly installed at the bottom of the magnetic frame 101.

[0025] The adjustment mechanism 2 includes a linkage knob 201, a single-row knob 202, and an adjustment hole 203. The linkage knob 201 is fixedly installed on the side of the magnetic frame 101, and a number of single-row knobs 202 are fixedly installed on the top of the frame 102. A number of adjustment holes 203 are fixedly installed on the surface of the frame 102, and each single-row knob 202 corresponds to one adjustment hole 203.

[0026] Furthermore, the main body 1 also includes placement holes 104 and magnets 105. Several placement holes 104 are fixedly installed on the surface of the base 103, and magnets 105 are fixedly installed at the bottom of the placement holes 104 inside the base 103.

[0027] Furthermore, the adjustment mechanism 2 also includes a gear 204 and a rack 205. The linkage knob 201 is fixedly mounted with the gear 204, and the gear 204 is fixedly connected to the rack 205.

[0028] Furthermore, the adjustment mechanism 2 also includes a connecting rod 206 and a sliding block 207. The rack 205 is fixedly connected to the connecting rod 206 of each adjustment hole 203, and the sliding block 207 is fixedly installed on the connecting rod 206.

[0029] Furthermore, the main body mechanism 1 also includes a column 106 and a limiting groove 107. The column 106 is fixedly installed between the frame 102 and the base 103, and the sliding block 207 is fixedly installed with the limiting groove 107.

[0030] Furthermore, the adjustment mechanism 2 also includes a screw 208 and a clamping plate 209. The single-row knob 202 is fixedly mounted with the screw 208, and the screw 208 is fixedly connected to the clamping plate 209.

[0031] Working principle: The frame 102 provides support and is a rectangular base 103 for placement on flat surfaces such as laboratory benches. Single or double rows of holes are arranged in a linear array on the frame 102, with hole spacing conforming to common laboratory standards, such as 9mm spacing. This facilitates the placement of EP tubes and ensures adequate spacing between them to prevent collisions.

[0032] A strong magnet 105, such as a neodymium iron boron magnet, is embedded at the bottom of each hole. This magnet is strong enough to generate sufficient magnetic force to attract the bottom of the EP tube. When the EP tube is placed in the hole, the magnet 105 holds the EP tube tightly with magnetic force, ensuring that it can be stably fixed on the magnetic frame 101 during experiments such as centrifugation and oscillation.

[0033] The linkage knob 201 and rack 205 are located inside both sides of the magnetic frame 101 and are interconnected via a transverse transmission shaft passing through the frame 102. In the transmission structure, gear 204 and rack 205 are linked. A drive gear 204 is mounted on the knob shaft end, meshing with the rack 205. The rack 205 is connected to the adjustment components of all holes in the same row via a connecting rod 206. When the knob is rotated, the drive gear 204 rotates, driving the rack 205 to move laterally. Each hole in the adjustment component corresponds to a sliding block 207. The sliding block 207 has a limiting groove 107 on its side, which fits tightly with the guide rail of the frame 102, ensuring that the sliding block 207 can only move in a straight line. Thus, when the rack 205 moves laterally, the connecting rod 206 pushes all the sliding blocks 207 in the holes to move simultaneously towards the center or outwards. Rotating the single or double-sided knob causes the rack 205 to move laterally via the gear 204, which in turn simultaneously pushes the sliding blocks 207 of all holes to move towards the center or outwards, thereby changing the inner diameter of the holes and achieving uniform adjustment of the diameter of a row of holes. For example, the diameter of a row of holes can be adjusted from 10mm to 14mm simultaneously to accommodate EP pipes of the same specification.

[0034] A single-row knob 202 is located at the top of each hole, connected to the clamping component inside the hole via a miniature screw 208. This independent design allows each hole to be adjusted individually, unaffected by others. Elastic clamping plates 209 consist of 2-4 symmetrically arranged elastic metal plates, such as stainless steel springs, on the inner wall of each hole. These springs have a certain degree of elasticity and can deform within a certain range. The ends of the springs have anti-slip silicone pads, which increase friction with the outer wall of the EP tube and prevent scratches. The screw 208 drives the slider up and down when the knob is rotated. The slider is connected to the elastic clamping plates 209 via a beveled structure. As the slider moves up and down, it expands or contracts the elastic clamping plates 209, thus changing the clamping diameter. The adjustment range is generally from 8 to 16 mm, accommodating various EP tube diameters. Rotating the knob of a single orifice individually causes the screw 208 to drive the slider to adjust the opening and closing degree of the elastic plate, precisely matching the diameter of the EP tube in that orifice. For example, on the same magnetic frame 101, the diameter of one orifice can be adjusted to fit a 1.5mL EP tube, while another orifice can be adjusted to fit a 2.0mL EP tube, facilitating the simultaneous use of test tubes of various sizes.

[0035] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
