Description

Technical Field

[0001] This invention relates to the field of microscopy, and more particularly to an inverted microscope. Background Technology

[0002] A microscope is a precision instrument that uses optical or electronic technology to magnify the details of tiny objects. It is primarily used to magnify minute objects that are invisible to the naked eye to the naked eye. Microscopes are widely used in fields such as medicine, biological research, industrial inspection, geological and materials analysis, and forensic evidence examination.

[0003] Existing inverted microscopes are generally designed as a single unit. However, dust tends to accumulate on the stage surface after prolonged use. Furthermore, the lack of a single unit structure to remove this dust and impurities affects the light transmittance of the stage, thus impacting the normal operation of the inverted microscope. Therefore, we provide an inverted microscope. Summary of the Invention

[0004] To address the problem in the aforementioned background technology that the difficulty in removing dust and impurities remaining on the stage affects the light transmittance of the stage, the present invention provides an inverted microscope.

[0005] The present invention is achieved by the following technical solution: an inverted microscope, including a base, an eyepiece for human observation, an objective lens for magnifying objects rotatably connected to the base, an illumination lamp for increasing brightness on the base, a transparent stage for placing samples fixedly connected to the base via a bracket, the transparent stage being directly above the objective lens and directly below the illumination lamp, a cleaning component on the base, a dust removal component on the base, and a cleaning component on the dust removal component.

[0006] As a further improvement to the above solution, the cleaning component includes two sets of frames symmetrically fixedly connected to the mirror base. A lead screw is rotatably connected to the frame, and a threaded block is threaded to the external thread of the lead screw. Two sets of movable plates are symmetrically arranged on the top of the transparent stage. A wiping cotton is provided at the bottom of the movable plate. A connecting rod is hinged between the movable plate and the threaded block on the same side through a hinge. Guide blocks are fixedly connected to both sides of the movable plate. Two sets of guide rods are symmetrically fixedly connected to the mirror base through a connecting seat, and the guide rods are slidably connected to the guide blocks on the same side.

[0007] As a further improvement to the above solution, the dust removal assembly includes an air chamber fixedly connected to a frame on the same side via a connecting bracket. A piston plate is movably connected inside the air chamber. A connecting rod is fixedly connected to one side of the piston plate, and the end of the connecting rod extends movably and sealably to the outside of the air chamber. Two sets of connecting rods are symmetrically hinged between the connecting rod and the threaded block on the same side via hinges. An air inlet pipe is fixedly connected to one side of the air chamber, and an air outlet pipe is also fixedly connected to one side of the air chamber. Air nozzles are fixedly connected to both sides of the objective lens, and the air nozzles are connected to the air outlet pipe on the same side. A filter screen is fixedly connected to the outside of the inlet of the air inlet pipe.

[0008] As a further improvement to the above solution, the cleaning assembly includes a rotating shaft rotatably connected to the filter screen, a scraper fixedly connected to the outside of the rotating shaft and in contact with the surface of the filter screen, a gear fixedly sleeved on the outside of the rotating shaft, and a rack fixedly connected to the threaded block and meshing with the gear on the same side.

[0009] As a further improvement to the above solution, a hollow column is fixedly connected to the mirror base, and a movable column is movably connected inside the hollow column, with the top of the movable column extending to the outside of the hollow column and fixedly connected to the lighting lamp. A first pin hole is opened on the hollow column, and a second pin hole is opened at equal intervals on the movable column. The same pin shaft is inserted inside the first pin hole and the second pin hole on the same horizontal line.

[0010] As a further improvement to the above solution, the threaded block has limit grooves on both sides and the limit grooves are slidably connected to the frame.

[0011] As a further improvement to the above solution, the size of the movable plate is matched with the size of the transparent stage, and the movable plate is fixedly connected to the wiping cotton by adhesive.

[0012] As a further improvement to the above solution, a limiting plate is fixedly connected to the connecting frame, and the limiting plate is slidably connected to the connecting rod on the same side.

[0013] As a further improvement to the above solution, a one-way valve is installed inside both the air inlet pipe and the air outlet pipe. The opening direction of the one-way valve inside the air inlet pipe is consistent with the air flow direction, and the opening direction of the one-way valve inside the air outlet pipe is consistent with the air flow direction.

[0014] As a further improvement to the above solution, the size of the scraper is matched with the size of the filter screen.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This invention allows the user to simultaneously rotate two sets of lead screws with both hands. The threaded connection between the lead screws and the threaded blocks, and the sliding connection between the limiting slide groove and the frame, enable the threaded blocks to move vertically upward. The sliding connection between the guide block and the guide rod, and the hinged connection between the movable plate and the threaded block and the connecting rod, allow the two sets of threaded blocks to move in opposite directions simultaneously as they move upward. This, in turn, moves the wiping cotton to wipe and clean the surface of the transparent stage, thus ensuring the light transmittance of the transparent stage.

[0017] 2. During the vertical upward movement of the threaded block, the present invention utilizes the hinged connection between the threaded block and the connecting rod and the second connecting rod, the sliding connection between the connecting rod and the limiting plate, and the sliding connection between the piston plate and the air chamber to push the piston plate to move, thereby pushing the air inside the air chamber out and blowing it out through the air outlet, thereby blowing away the floating dust on the surface of the objective lens, further ensuring the normal use of the device.

[0018] 3. This invention allows the user to simultaneously rotate two sets of lead screws in opposite directions with both hands, thereby driving two sets of movable plates to move in opposite directions. At this time, the two sets of movable plates can automatically clamp and fix the glass slide, thus ensuring the stability of the sample during observation and making it highly practical.

[0019] 4. During the vertical movement of the threaded block, the present invention can also drive the rack to move together. By utilizing the meshing between the rack and the gear, and the rotational engagement between the shaft and the filter screen, the rack can drive the shaft to rotate when it moves. The rotation of the shaft will drive the scraper to make a circular motion, thereby scraping off the dust attached to the surface of the filter screen and thus preventing the filter screen from becoming clogged.

[0020] 5. This invention allows the vertical height of the lighting lamp to be adjusted by extending and retracting the movable column inside the hollow column, thereby ensuring good light transmission and facilitating sample observation. By inserting the pin into the pin hole one and pin hole two on the same horizontal line, the position of the lighting lamp can be fixed, making it highly practical.

[0021] 6. The present invention connects and fixes the wiping cotton to the movable plate by adhesive bonding, which makes it easy to replace the wiping cotton after long-term use, thereby ensuring the good cleaning effect of the wiping cotton on the device. Attached Figure Description

Detailed Implementation

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] The cleaning assembly includes two sets of frames 101 symmetrically fixedly connected to the mirror base 1. A lead screw 102 is rotatably connected to each frame 101, and a threaded block 103 is threadedly connected to the external thread of the lead screw 102. Two sets of movable plates 104 are symmetrically arranged on the top of the transparent stage 5. A wiping cotton 105 is provided at the bottom of each movable plate 104. A connecting rod 106 is hinged between the movable plate 104 and the threaded block 103 on the same side. Guide blocks 107 are fixedly connected to both sides of the movable plate 104. The mirror base 1 is symmetrically connected via connecting seats. Two sets of guide rods 108 are connected and slidably connected to the guide block 107 on the same side. The threaded block 103 has limit grooves on both sides and the limit grooves are slidably connected to the frame 101, which can play a certain guiding role in the vertical movement of the threaded block 103. The size of the movable plate 104 matches the size of the transparent platform 5, which is convenient for thoroughly cleaning the transparent platform 5. The movable plate 104 is fixedly connected to the wiping cotton 105 by adhesive, which is convenient for disassembly and replacement of the wiping cotton 105.

[0034] The dust removal assembly includes an air chamber 201 fixedly connected to a frame 101 on the same side via a connecting bracket. A piston plate 202 is movably connected inside the air chamber 201. A connecting rod 203 is fixedly connected to one side of the piston plate 202, and the end of the connecting rod 203 extends movably and sealably to the outside of the air chamber 201. Two sets of connecting rods 204 are symmetrically hinged between the connecting rod 203 and the threaded block 103 on the same side via hinges. An air inlet pipe 205 is fixedly connected to one side of the air chamber 201, and an air outlet pipe 206 is also fixedly connected to one side of the air chamber 201. Air outlet nozzles 207 are fixedly connected to both sides of the objective lens 3. Furthermore, the air outlet 207 is connected to the air outlet pipe 206 on the same side, and a filter screen 208 is fixedly connected to the outside of the air inlet pipe 205. A limiting plate 10 is fixedly connected to the connecting frame, and the limiting plate 10 is slidably connected to the connecting rod 203 on the same side, which can play a certain guiding role in the horizontal movement of the connecting rod 203.

The opening direction of the one-way valve inside the air inlet pipe 205 is consistent with the air inflow direction, and the opening direction of the one-way valve inside the air outlet pipe 206 is consistent with the air outflow direction, which can ensure the stable operation of air extraction.

[0035] The cleaning assembly includes a rotating shaft 301 rotatably connected to the filter screen 208. A scraper 302 is fixedly connected to the outside of the rotating shaft 301 and contacts the surface of the filter screen 208. A gear 303 is also fixedly sleeved on the outside of the rotating shaft 301. A rack 304 is fixedly connected to the threaded block 103 and meshes with the gear 303 on the same side. The size of the scraper 302 matches the size of the filter screen 208, which can ensure the thorough cleaning of the filter screen 208.

[0036] The implementation principle of an inverted microscope in this embodiment is as follows: First, the user simultaneously rotates two sets of lead screws 102 with both hands. Through the threaded connection between the lead screws 102 and the threaded blocks 103, and the sliding connection between the limiting slide groove and the frame 101, the threaded blocks 103 can be moved vertically upwards. Utilizing the sliding connection between the guide block 107 and the guide rod 108, and the hinged connection between the movable plate 104 and the threaded blocks 103 and the connecting rod 106, the upward movement of the two sets of threaded blocks 103 can drive the two sets of movable plates 104 to move simultaneously in opposite directions, thereby driving the wiping cotton 1... 05. The surface of the transparent stage 5 is wiped clean by moving the stage 5, thus ensuring the light transmittance of the transparent stage 5. At the same time, during the vertical upward movement of the threaded block 103, the hinge action between the threaded block 103 and the connecting rod 203 and the connecting rod 204, the sliding engagement between the connecting rod 203 and the limiting plate 10, and the sliding engagement between the piston plate 202 and the air chamber 201 are used to push the piston plate 202 to move, thereby pushing the air inside the air chamber 201 out and blowing it out through the air outlet 207, thereby blowing away the dust on the surface of the objective lens 3, and then clamping the objective lens 3. The glass slide of the sample is placed on the transparent stage 5. Then, the illumination lamp 4 is turned on. The user then simultaneously rotates both sets of lead screws 102 in opposite directions, causing the two sets of movable plates 104 to move in opposite directions. At this time, the two sets of movable plates 104 automatically clamp and fix the glass slide, ensuring the stability of the sample during observation. Next, the user observes the sample in detail through the magnification of the objective lens 3 and the eyepiece 2. Finally, after use, the glass slide is removed, and the lead screws 102 are rotated in the opposite direction again. At this time, the movable plates 104 automatically reset, and simultaneously, the piston plate 202 also automatically... When the piston plate 202 resets, it can draw outside air into the air chamber 201. The filter screen 208 can filter dust and impurities. During the vertical movement of the threaded block 103, it can also drive the rack 304 to move together. Utilizing the meshing between the rack 304 and the gear 303, and the rotational engagement between the rotating shaft 301 and the filter screen 208, the rack 304 can drive the rotating shaft 301 to rotate when it moves. The rotation of the rotating shaft 301 will drive the scraper 302 to make a circular motion, thereby scraping off the dust attached to the surface of the filter screen 208 and preventing the filter screen 208 from becoming clogged.

[0037] Example 2:

[0038] This embodiment is an improvement on embodiment 1, further characterized by the following: a hollow column 6 is fixedly connected to the mirror base 1, and a movable column 7 is movably connected inside the hollow column 6, with the top of the movable column 7 extending to the outside of the hollow column 6 and fixedly connected to the lighting lamp 4. A first pin hole is provided on the hollow column 6, and a second pin hole 8 is provided at equal intervals on the movable column 7. The same pin shaft 9 is inserted into the first pin hole and the second pin hole 8 on the same horizontal line. By driving the movable column 7 to extend and retract inside the hollow column 6, the vertical height position of the lighting lamp 4 can be adjusted, thereby ensuring good light transmission and facilitating the observation of the sample. By inserting the pin shaft 9 into the first pin hole and the second pin hole 8 on the same horizontal line, the position of the lighting lamp 4 can be fixed.
