Description

Technical Field

[0001] This utility model relates to the field of microscope technology, specifically to an optical microscope with an adjustable base. Background Technology

[0002] An optical microscope is an instrument that magnifies tiny objects using optical principles. It magnifies the image of a sample through an optical system, allowing the human eye to observe minute structures invisible to the naked eye. The working principle of an optical microscope is based on the refraction of light. When light rays pass through the microscope's lens system, they are focused, thus forming a magnified image. Optical microscopes are important tools in scientific research and technological development, playing a crucial role in the advancement of modern science and technology.

[0003] Most existing optical microscopes only have anti-slip pads on the bottom of the base. However, some operating tables and environments may have surfaces that are too smooth or of varying sizes, which can cause the base of some optical microscopes to be unstable on the table, thus affecting the observation of the optical microscope. Utility Model Content

[0004] The purpose of this invention is to provide an optical microscope with an adjustable base to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an optical microscope with an adjustable base, comprising an optical microscope body, a base and a sample stage, wherein the base is provided with an adjustment part for reinforcement when the optical microscope body is used for observation;

[0006] The adjustment unit includes a slide groove, a slide plate, a lever, a knob, a ratchet, a shifting groove, a connecting block, a pull rod, a pawl, a spring one, a support rod, a spring two, a connecting post, a suction cup, a connecting tube, a through hole, a pressure plate, and a spring three. The slide groove is located on the inner side of the base, and the slide plate is slidably connected to the inner side of the slide groove. Since the lever passes through the slide plate and is rotatably connected, when the lever is shifted, it causes the slide plate to slide within the slide groove. The top surface of the slide plate passes through and is rotatably connected to the lever. When the lever is shifted, it causes the slide plate to slide within the slide groove, causing the connecting post to move the suction cup.

[0007] Preferably, a knob is rotatably connected through the top surface of the base, a ratchet is rotatably connected through the knob, and an actuation groove is provided on the bottom surface of the knob.

[0008] Preferably, a connecting block is fixedly connected to the top surface of the base, and a pull rod is slidably connected through the inner side of the connecting block.

[0009] Preferably, a pawl is fixedly connected to one end of the lever near the ratchet. When the knob is turned, the ratchet will rotate, causing the teeth of the ratchet to abut against the pawl and force the pawl to retract, thus limiting the ratchet. A spring is fixedly connected between the pawl and the inner side of the connecting block.

[0010] Preferably, a support rod is fixedly connected to the inner side of the slide groove, the support rod passes through the slide plate and is slidably connected, and a spring is fixedly connected between the side of the slide plate and the inner side of the slide groove.

[0011] Preferably, a connecting column is connected through and fixedly connected to the surface of the skateboard. When the base is pressed down, the base applies pressure to the suction cup through the skateboard and the connecting column to adhere to the table surface. The bottom end of the connecting column is connected through and fixedly connected to the suction cup.

[0012] Preferably, a connecting tube is slidably connected through the inner side of the connecting column, and through holes are opened on the sides of the top and bottom ends of the connecting tube. Pressing down on the pressure plate allows air to enter the suction cup, thereby making the suction cup easy to pull out. The pressure plate is fixedly connected through the connecting tube, and a spring is fixedly connected between the pressure plate and the sliding plate.

[0013] Compared with the prior art, this utility model provides an optical microscope with an adjustable base, which has the following advantages:

[0014] 1. This adjustable optical microscope features a lever that passes through and rotates through a sliding plate. The sliding plate, located within a groove, is also slidably connected, limiting its position. When the lever is moved, the sliding plate slides within the groove, compressing a spring. This movement of the sliding plate moves the connecting column, which in turn moves the suction cup. When the suction cup reaches the desired position, the base can be pressed down, applying pressure to the suction cup via the sliding plate and connecting column to adhere it to the stage. The adjustable suction cup allows for adhesion to various tabletop sizes, accommodating a wider range of operating surfaces for observation.

[0015] 2. This adjustable optical microscope base allows for easy removal of the base's reinforcement by pressing down on the pressure plate. This causes the pressure plate to move the connecting tube downwards. After the connecting tube moves a certain distance downwards, the through hole at the lower end of the connecting tube enters the inside of the suction cup, connecting the through holes at the top and bottom of the connecting tube. This allows air to enter the suction cup, making it easy to pull out. Then, pulling the lever removes the pawl from the ratchet wheel, resetting the slide plate. This simple pressing and pulling operation allows the base to adapt to different environments, making operation convenient and quick, thus improving the efficiency of the optical microscope itself.

[0022] like Figures 1-5 As shown, this utility model provides a technical solution: an optical microscope with an adjustable base, including an optical microscope body 1, a base 3 and a sample stage 4, wherein the base 3 is provided with an adjustment part 2 for reinforcement when the optical microscope body 1 is observed.

[0023] The adjustment unit 2 includes a slide groove 21, a slide plate 22, a lever 23, a knob 24, a ratchet 25, a shifting groove 26, a connecting block 27, a pull rod 28, a pawl 29, a first spring 210, a support rod 211, a second spring 212, a connecting column 213, a suction cup 214, a connecting pipe 215, a through hole 216, a pressure plate 217, and a third spring 218. The slide groove 21 is located inside the base 3, and the slide plate 22 is slidably connected to the inner side of the slide groove 21. When the knob 24 is rotated, it will drive the shifting groove 26 to shift the lever 23. However, because the lever 23... A sliding plate 22 is rotatably connected to the top surface of the base 3, and is also slidably connected within the slide groove 21. The slide plate 22 is limited by the slide groove 21, further causing the lever 23 to slide within the slide groove 21 when it is activated. The lever 23 is rotatably connected to the top surface of the slide plate 22. When the lever 23 is activated, the slide plate 22 slides within the slide groove 21, and the slide plate 22 compresses the spring 212. Simultaneously, the sliding of the slide plate 22 causes the connecting post 213 to move, which in turn moves the suction cup 214. A knob 24 is rotatably connected to the top surface of the base 3, and a ratchet 25 is fixedly connected to the knob 24. A lever groove 26 is provided on the bottom surface of the knob 24. A connecting block 27 is fixedly connected to the top surface of the base 3, and a pull rod 28 is slidably connected to the inner side of the connecting block 27. A pawl 29 is fixedly connected to one end of the lever 28 near the ratchet 25. Rotating the knob 24 causes the ratchet 25 to rotate, causing the teeth of the ratchet 25 to engage with the pawl 29 and force it to retract, thus limiting the ratchet 29's position. A spring 210 is fixedly connected between the pawl 29 and the inner side of the connecting block 27. A support rod 211 is fixedly connected to the inner side of the slide groove 21, passing through the slide plate 22 and slidably connected. A spring 212 is fixedly connected between the side of the slide plate 22 and the inner side of the slide groove 21. A connecting post 213 is fixedly connected to the surface of the sliding plate 22. When the suction cup 214 moves to the appropriate position, the base 3 can be pressed down, so that the base 3 applies pressure to the suction cup 214 through the sliding plate 22 and the connecting post 213 to stick to the table surface. The suction cup 214, which can be retracted and expanded at will, can be used to adsorb tabletops of different sizes. The bottom end of the connecting post 213 is fixedly connected to the suction cup 214. A connecting tube 215 is slidably connected through the inner side of the connecting column 213. The top and bottom sides of the connecting tube 215 are provided with through holes 216. Pressing down the pressure plate 217 causes the pressure plate 217 to drive the connecting tube 215 to move downward. After the connecting tube 215 moves downward a certain distance, the through hole 216 at the lower end of the connecting tube 215 enters the inner side of the suction cup 214, so that the through holes 216 at the top and bottom of the connecting tube 215 are connected, allowing air to enter the suction cup 214 and thus the suction cup 214 can be easily pulled out. The pressure plate 217 is fixedly connected through the connecting tube 215. A spring 218 is fixedly connected between the pressure plate 217 and the sliding plate 22.

[0024] Based on the above implementation, when the optical microscope body 1 is used to inspect a sample, the position where the optical microscope body 1 needs to be placed is first determined. Then, the position is adjusted according to the smoothness and size of the surface of the placement position, such as a table or workbench. The knob 24 is rotated, which drives the ratchet 25 to rotate, causing the teeth of the ratchet 25 to abut against the pawl 29 and force the pawl 29 to retract, thus limiting the ratchet 25. Simultaneously, the rotation of the knob 24 drives the actuating groove 26 to actuate the lever 23. However, since the lever 23 passes through the slide plate 22 and is rotatably connected, and the slide plate 22 is slidably connected within the slide groove 21, the slide plate... The slide 22 is limited by the slide groove 21, which further causes the lever 23 to slide within the slide groove 21 when it is turned. The slide 22 compresses the spring 212. At the same time, the slide 22 moves the connecting column 213 together, causing the connecting column 213 to move the suction cup 214. When the suction cup 214 moves to the appropriate position, the base 3 can be pressed down, so that the base 3 applies pressure to the suction cup 214 through the slide 22 and the connecting column 213 to stick to the table surface. The suction cup 214, which can be retracted and expanded at will, can be used to attach to tabletops of different sizes to adapt to more operating tables for observation of the optical microscope body 1.

[0025] When it is necessary to remove the reinforcement of the base 3, the pressure plate 217 can be pressed down, causing the pressure plate 217 to move the connecting tube 215 downward. After the connecting tube 215 moves downward a certain distance, the through hole 216 at the lower end of the connecting tube 215 enters the inside of the suction cup 214, making the through holes 216 at the top and bottom of the connecting tube 215 connected. This allows air to enter the suction cup 214, making the suction cup 214 easy to pull out. Then, the pull rod 28 is pulled so that the pawl 29 no longer limits the ratchet 25 to reset the slide plate 22. Only pressing and pulling operations are needed to complete the operation, making the base 3 adaptable to different environments. The operation is convenient and quick, thereby improving the efficiency of the optical microscope body 1.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
