Description

Technical Field

[0001] The utility model relates to the technical field of oscillators, in particular to an oscillator with a displacement reducing structure. Background Art

[0002] An oscillator is an experimental device mainly used for solution mixing and reaction heating. Its working principle is to use a motor to drive centrifuge tubes, test tubes, beakers and other vessels mounted on a vibration table to vibrate in a water bath, so that the solution can be evenly mixed and heated.

[0003] According to application number 201620526114.4, a test tube oscillator is disclosed, in which test tubes of different specifications are fixed by arranging a fixing component in the test tube accommodating cavity. Specifically, the elastic deformation characteristics of the upper fixing profile and the lower fixing profile are utilized to achieve adaptability to test tubes of different sizes. At the same time, the fixing component can enable the test tube to achieve synchronous oscillation with the oscillator body, thereby improving the efficiency and oscillation effect of the oscillator.

[0004] However, although the above patent content can improve the oscillation effect of the oscillator when in use, when conducting experiments, the conventional oscillator has a relatively smooth experimental table surface, so that a large shift of the oscillator may knock over other instruments and equipment on the experimental table or even fall; even if the oscillator is placed on the ground, it may still shift from the placement position to the passage, causing inconvenience in passage, tripping of people, damage to instruments and other risks. Utility Model Content

[0005] The utility model aims to provide an oscillator with a displacement reducing structure, so as to solve the problem that the oscillator proposed in the above background technology is prone to large displacement during use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an oscillator with a displacement reducing structure, comprising an oscillator body, a protective pad body, a control button and an oscillation seat, the bottom of the oscillator body is provided with a protective pad body, the surface of the oscillator body is provided with a control button, and an oscillation seat is provided at one end of the oscillator body away from the protective pad body.

[0007] Preferably, both sides of the oscillator body are welded with fixing seats, and a driving motor is arranged inside the fixing seat.

[0008] Preferably, the output end of the driving motor is connected to a rotating rod via a coupling, and the surface of the rotating rod is connected to a rotating disk.

[0009] Preferably, a connecting rod is rotatably connected to one side of the rotating disk, a suction cup is connected to one side of the connecting rod, and a guide block is slidably connected between the connecting rod and the fixing seat.

[0010] Preferably, a connecting seat is welded to one side of the bottom of the oscillator body close to the protective pad body, and a fixing frame is arranged inside the connecting seat.

[0011] Preferably, a push block is slidably connected inside the fixing frame, a pull rod is connected to the top of the push block, and a limiting spring is welded and connected between the push block and the fixing frame.

[0012] Preferably, both sides of the connecting seat close to the push block are rotatably connected with limiting rods, and a return spring is welded and connected between the limiting rod and the connecting seat.

[0013] Preferably, a locking groove is provided on one side of the protective pad body close to the limiting rod.

[0014] Compared with the prior art, the beneficial effect of the utility model is that the oscillator with a displacement reduction structure starts the driving motor so that the driving motor can rotate the rotating disk connected to the surface through the rotating rod connected to the output end, and then the rotating disk can drive the connecting rod connected to the surface to follow the rotation when rotating, so that the connecting rod can rotate inside the fixed seat, and then the connecting rod can move the connected suction cup after moving, so that the suction cup can be attracted to the smooth experimental table surface, so that the oscillator can be more stable when in use, so that the above-mentioned problem of easy displacement can be solved when the oscillator is in use.

[0015] 1. The oscillator with a displacement reduction structure is usually prone to large displacement during experimental operation when the oscillator is in use, which may cause unexpected risks when the oscillator is in use. By starting the driving motor, the driving motor can rotate the rotating rod connected to the output end, so that the rotating rod can rotate the rotating disk connected to the surface when rotating, so that the rotating disk can rotate the connecting rod when rotating, so that the connecting rod can rotate inside the fixed seat, and then the connecting rod can move the connected suction cup after moving, so that the suction cup can be sucked to the smooth experimental table, so that the oscillator can be more stable when in use;

[0016] 2. For the oscillator with a displacement reduction structure, when the oscillator is in use, it is usually not easy to replace the bottom protective pad, which makes it easy to be worn after long-term use, resulting in tilting when placed, which aggravates the displacement of the oscillator. By pulling the pull rod, the pull rod can pull the connected push block, so that the push block can squeeze the connected limit spring, so that the reset effect of the reset spring can drive the connected limit rod to separate the locking groove, so that the oscillator can quickly take out the worn protective pad body when it is in use, so that the oscillator can be replaced more conveniently.
