Description

Technical Field

[0001] This utility model belongs to the technical field of metallographic inlay liquid stirring device, specifically relating to a steel core silicone stirring rod. Background Technology

[0002] Thermosetting resin inserts, which are widely used in the preparation of metallographic samples, need to be thoroughly mixed before use. This is usually done using a wooden or glass stirring rod.

[0003] The inlay material is highly viscous and easily hardens, making it easy to adhere to the rough surface of the wooden stirring rod. After use, the residual inlay material hardens and adheres to the rod, making it difficult to clean and remove completely. Therefore, wooden stirring rods are basically disposable items that need to be replaced frequently, increasing the cost of experimental consumables.

[0004] Commonly used glass rods have a smooth surface and are not easy to stick to, but the material is brittle and hard. When stirring and scraping the container, they can easily scratch the inner wall of expensive inlaid molds. At the same time, glass rods are fragile and can break if handled carelessly, causing the experiment to be interrupted.

[0005] There is a lack of a dedicated stirring tool in the existing technology that is wear-resistant, non-adhesive, soft and does not damage the mold, and is economical and durable. Therefore, a steel-core silicone stirring rod is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a steel-core silicone stirring rod, which has the advantages of being easy to clean, durable and not damaging to the mold. It solves the problem of frequent replacement and waste caused by the adhesion and curing of the inlay material in the existing wooden stirring rod, as well as the problem of glass stirring rods easily scratching the mold and posing a safety hazard of breakage.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a steel-core silicone stirring rod, including a steel column, one end of which is fixedly connected to a round handle, and a silicone tube is sleeved around the outer periphery of the steel column. The length of the silicone tube is 1 cm longer than the length of the steel column, and one end of the silicone tube extends beyond the end of the steel column to form a 1 cm long hollow tube section. The hollow tube section is a pure silicone hollow tube structure without steel column filling.

[0008] Preferably, the silicone tube has a wall thickness of 1.5-2.5 mm and is made of high-temperature resistant silicone.

[0009] Preferably, the steel column has a diameter of 4-8mm and a length of 20-30cm, and the round handle has a diameter of 2-3cm and a thickness of 1-1.5cm.

[0010] Preferably, the silicone tube is fixed to the steel column by heat shrinking, and the silicone tube tightly covers the surface of the steel column.

[0011] Preferably, the steel column and the round handle are integrally formed, and the steel column and the round handle are made of stainless steel.

[0012] Preferably, the surface of the round handle is provided with anti-slip texture.

[0013] Preferably, the outer surface of the silicone tube is provided with spiral reinforcing ribs, which are integrally formed with the silicone tube.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model has a simple structure and low manufacturing cost. It uses a flexible silicone tube to wrap the internal steel wire core, combining flexibility and rigidity. One end is fixed with a round handle for comfortable gripping.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1 As shown, a steel-core silicone stirring rod includes a steel column 1, which forms the core skeleton of the entire stirring rod. This structural strength prevents bending and deformation when stirring viscous materials, ensuring efficient and powerful stirring. The steel column 1 and the round handle 2 are integrally molded. Both the steel column 1 and the round handle 2 are made of stainless steel, with the steel column 1 made of 304 or 316 stainless steel, suitable for laboratory chemical environments. The round handle 2 is fixedly connected to one end of the steel column 1, providing a gripping point for stirring operations. The seamless connection between the steel column 1 and the handle facilitates cleaning and prevents dirt accumulation.

[0023] A silicone tube 3 is fitted around the outer periphery of the steel column 1. The length of the silicone tube 3 is 1 cm longer than the length of the steel column 1. One end of the silicone tube 3 extends beyond the end of the steel column 1 to form a 1 cm long hollow tube segment 4. The hollow tube segment 4 is a pure silicone tube structure without the steel column 1 filling. The silicone tube 3 is in direct contact with the insert material. The smooth and oleophobic properties of the silicone tube 3 make it difficult for the insert material to adhere. At the same time, the soft silicone protects the inner wall of the insert mold from being scratched.

[0024] The 1cm pure silicone hollow tube section 4 reserved at the end is soft and elastic. After stirring, it can easily scrape off and peel off the stubborn residual inserts on the edge and bottom of the container, achieving a thorough cleaning and solving the problem of hard-to-clean residue after the wood stirring stick has hardened, thus reducing material waste and cleaning water.

[0025] The specific design of the aforementioned key components will be discussed in detail below:

[0026] The silicone tube 3 has a wall thickness of 1.5-2.5mm and is made of high-temperature resistant silicone. A thickness less than 1.5mm results in insufficient mechanical strength, making it prone to wear, tearing, or puncture by the internal steel pillar 1 during frequent scraping of the mold's inner wall and stirring of high-viscosity inserts, thus reducing product lifespan. A thickness greater than 2.5mm leads to an overly rigid rod, losing the unique flexibility of silicone material and weakening its ability to protect the mold's inner wall and remove residual material, while also increasing costs. The 1.5-2.5mm wall thickness gives the silicone tube 3 excellent flexibility, wear resistance, and puncture resistance, enabling it to withstand the intensity of long-term stirring operations.

[0027] Metallographic mounting processes often involve exothermic reactions, and sometimes a warm water bath is used to reduce the viscosity of the mounting material. Tools must be able to withstand temperatures above 60°C for short periods. Laboratory-grade high-temperature resistant silicone rubber has a temperature range of -60°C to over 200°C. It is non-toxic, odorless, chemically inert, and will not contaminate samples. It adapts to temperature changes during experiments, preventing softening, deformation, or aging.

[0028] The steel column 1 has a diameter of 4-8mm and a length of 20-30cm, while the round handle 2 has a diameter of 2-3cm and a thickness of 1-1.5cm. The 4-8mm diameter of the steel column provides the necessary structural rigidity. A diameter that is too small results in weak stirring and easy bending; a diameter that is too large leads to excessive weight, cumbersome operation, and requires a thicker silicone coating, increasing cost. The 20-30cm length is designed for the depth of standard metallographic inlay molds, allowing the stirring rod to easily reach the bottom of the container while providing a sufficiently long handle for safe and convenient operation. The stirring rod has a stable center of gravity and provides powerful stirring, making it suitable for most sizes of inlay cups on the market.

[0029] The appropriately sized round handle 2 allows the operator to comfortably, effortlessly, and precisely control the stirring action, reducing hand fatigue from prolonged operation. The surface of the round handle 2 is provided with anti-slip textures 5. In laboratory environments where the operator's hands are contaminated with water droplets, oil stains, or powder, the smooth metal surface is prone to slipping. The anti-slip textures 5 increase the surface friction coefficient, ensuring a safe and stable grip even in wet and slippery conditions, preventing slippage under pressure.

[0030] The silicone tube 3 is fixed to the steel column 1 by heat shrinking, with the silicone tube 3 tightly covering the surface of the steel column 1. Upon heating, the silicone tube 3 shrinks, creating a strong clamping force and friction with the surface of the steel column 1, preventing relative sliding or rotation between the two. The resulting joint is smooth and seamless, avoiding the accumulation of dirt and grime in gaps, facilitating cleaning, and eliminating the need for adhesives throughout the process, thus preventing sample contamination due to adhesive dissolution and meeting the high cleanliness requirements of the laboratory.

[0031] The outer surface of the silicone tube 3 is provided with spiral reinforcing ribs 6, which are integrally formed with the silicone tube 3. A plain, smooth silicone tube 3 has low shear efficiency and insufficient axial stiffness when stirring high-viscosity fluids. The spiral structure generates stronger radial flow and shear force during rotation, enabling faster and more uniform mixing of the embedded material and avoiding air bubbles or uneven mixing. The reinforcing ribs 6 give the silicone tube 3 a certain degree of bending resistance, improving the stirring effect. The tube is manufactured in one piece with the silicone tube 3, resulting in a seamless, non-detachable structure with good structural integrity and easy cleaning.

[0032] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
