Description

Technical Field

[0001] This utility model relates to an elastic element, specifically a corrosion-resistant oscillating disc clamping spring.

[0002] This utility model also relates to an oscillation device, specifically an oscillator. Background Technology

[0003] In chemical analysis and biological testing laboratories, shakers are indispensable mixing devices used to thoroughly mix various liquid reagents and samples in sample vials, ensuring uniform dissolution and thus improving the accuracy and precision of test results. Currently, common shakers use multiple sets of metal springs on the shaking plate to hold the sample vials.

[0004] However, laboratory environments often contain a significant amount of acidic volatile substances. These substances diffuse into the air, exposing the clamping springs inside the shaker to a corrosive atmosphere for extended periods. The springs, in particular, are highly susceptible to chemical corrosion due to their typically ordinary metal construction and lack of effective protection. Corrosion not only leads to spring elasticity failure and insufficient clamping force, but in severe cases, it can cause spring breakage, resulting in sample vials falling off and breaking, causing sample loss, cross-contamination, and even equipment damage, posing significant safety hazards. Currently, there is a lack of a simple, low-cost solution that effectively prevents spring corrosion.

[0005] Therefore, there is an urgent need for an improved anti-corrosion solution for the oscillator clamping spring to solve the problems of easy corrosion and short lifespan in highly corrosive experimental environments. Utility Model Content

[0006] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a corrosion-resistant oscillating disc clamping spring and its oscillator with double protection of thermoplastic rubber tube covering and end anti-rust layer.

[0007] The technical problem to be solved by this utility model is achieved through the following technical solution: a corrosion-resistant oscillating disc clamping spring, comprising three sets of clamping springs arranged from top to bottom: upper, middle and lower, with the upper and lower sets of clamping springs having different installation directions; A thermoplastic rubber tube is fitted onto the outer circumferential surface of each clamping spring, and a clamping gap is formed between all the thermoplastic rubber tubes for clamping the workpiece. The outer circumferential surfaces at both ends of the clamping spring are coated with an anti-rust layer.

[0008] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned corrosion-resistant oscillating disc clamping spring has the upper and lower sets of clamping springs installed in perpendicular directions.

[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the corrosion-resistant oscillating disc clamping spring described above, wherein the inner circumferential surface of the thermoplastic rubber tube is in contact with the outer circumferential surface of the clamping spring.

[0010] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the anti-corrosion oscillating disc clamping spring described above, wherein the wall thickness of the thermoplastic rubber tube is 2~3mm.

[0011] The technical problem to be solved by this utility model can also be achieved through the following technical solution: an oscillator, including an oscillator body, an oscillator switch, an oscillator amplitude adjustment knob, an oscillator frequency adjustment knob, an amplitude adjustment display screen, and a frequency adjustment display screen are provided on the outer wall of the oscillator body, a vibration motor is fixedly provided on the top of the oscillator body, an oscillating disk is fixedly provided on the power output end of the vibration motor, an installation groove is opened on the top of the oscillating disk, and a number of hanging holes are fixedly provided on the inner wall of the installation groove, which has the corrosion-resistant oscillating disk clamping spring of the above technical solution, and the two ends of the clamping spring are hung in the hanging holes of the installation groove.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are: (1) By wrapping a thermoplastic rubber tube around the clamping spring that is in contact with air, a physical barrier is constructed, which effectively isolates the spring body from direct contact with corrosive atmospheres such as acidic volatiles in the laboratory environment, fundamentally avoiding the problem of chemical corrosion caused by hydrogen ion adsorption of the spring, and significantly improving the durability and service life of the spring and the entire oscillator.

[0013] (2) The thermoplastic rubber tube not only serves as an isolation device, but its material has a large coefficient of friction and elastic deformation capability. When clamping the sample bottle, the rubber tube deforms under pressure, increasing the contact area with the bottle body and generating greater friction, which makes the sample bottle firmly clamped and effectively prevents slippage, flying and other accidents during high-speed oscillation, thus improving the safety and reliability of the experiment.

[0014] (3) The hooks at both ends of the clamping spring are usually stress-concentrated and easily damaged parts, so special anti-rust treatment has been carried out, namely, coating with anti-rust paint, thus forming a second line of defense. This ensures that even if corrosive media bypass or seep into the end of the rubber tube, the most vulnerable part of the spring can still be protected, achieving overall and comprehensive corrosion protection for the spring.

[0015] (4) This utility model only requires adding a rubber tube and end coating to the existing spring structure. It does not require complex modification of the oscillator body. The structure is simple, easy to implement, and the cost increases very little, but it brings great performance improvement. It is very conducive to upgrading and modifying existing equipment and promoting its application in new products. Attached Figure Description

[0018] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0019] Example 1, referring to Figure 1-2 A corrosion-resistant oscillating disc clamping spring includes three sets of clamping springs 1 arranged from top to bottom: upper, middle, and lower. The number of clamping springs 1 in each set can be selected according to the usage requirements. The installation directions of the upper and lower sets of clamping springs 1 are perpendicular. A thermoplastic rubber tube 2 is fitted on the outer circumferential surface of each clamping spring 1. On the one hand, it serves as a physical barrier to prevent direct contact with corrosive atmospheres such as acidic volatiles, thus fundamentally avoiding the chemical corrosion problem caused by hydrogen ion adsorption. On the other hand, it can increase the contact area with the workpiece to be clamped, such as a bottle, thereby generating greater friction and allowing the sample bottle to be firmly clamped. The inner circumferential surface of the thermoplastic rubber tube 2 is in contact with the outer circumferential surface of the clamping spring 1, and a clamping gap for clamping the workpiece is formed between all the thermoplastic rubber tubes 2. The wall thickness of the thermoplastic rubber tube 2 is 2~3mm. The outer circumferential surfaces of both ends of the clamping spring 1 are coated with an anti-rust layer.

[0020] In Example 1, the anti-rust layer can be anti-rust paint, so that the area of ​​the clamping spring 1 not covered by the thermoplastic rubber tube 2 is protected from corrosion by hydrogen ions in the air acid, thereby reducing its wear.

[0021] Example 2: An oscillator includes an oscillator body 3. The outer wall of the oscillator body 3 is equipped with an oscillator switch 4, an oscillator amplitude adjustment knob 5, an oscillator frequency adjustment knob 11, an amplitude adjustment display screen 6, and a frequency adjustment display screen 12. These are existing technologies, and their specifications can be selected according to usage requirements. A vibration motor is fixedly installed on the top of the oscillator body 3. The vibration motor is also existing technology, and its specifications can be selected according to usage requirements. An oscillating disk 7 is fixedly installed on the power output end of the vibration motor. The oscillating disk 7 can be square. A mounting groove 8 is opened on the top of the oscillating disk 7. The mounting groove 8 can be square. Several hanging holes 9 are fixedly installed on the inner wall of the mounting groove 8. The hanging holes 9 can be circular. It has the corrosion-resistant oscillating disk clamping springs of Example 1. The two ends of the clamping springs 1 are hung in the hanging holes 9 of the mounting groove 8.

[0022] In Example 2, the oscillator with corrosion-resistant oscillating disc clamping spring operates on almost the same principle as a conventional oscillator. Simply release the clamping spring 1, place the sample bottle 10 into the clamping spring 1 of the oscillating disc, ensuring the bottom of the sample bottle 10 contacts the bottom of the oscillating disc, then turn on the oscillator, adjust the appropriate frequency and amplitude, and the oscillating disc will reciprocate. The material in the sample bottle 10 will be continuously impacted during this reciprocating motion, generating relative motion and thus achieving stirring and uniformity. After vibration ends, adjust the frequency and amplitude to 0, turn off the device, remove the sample bottle 10, and the work cycle is complete.
