Description

Technical Field

[0001] This utility model relates to the field of microscope technology, and in particular to a microscope LED housing structure that improves the stability of the light source. Background Technology

[0002] A microscope is a precision optical instrument primarily used to magnify tiny objects that are invisible to the naked eye, making their details clearly visible. It utilizes the imaging principle of a convex lens, using two magnification processes—the objective lens and the eyepiece—to magnify tiny objects to a size that the human eye can distinguish. The objective lens, located close to the object being observed, is responsible for the first magnification, forming an inverted real image. The eyepiece, located close to the observer's eye, is responsible for the second magnification, further magnifying the real image formed by the objective lens to form an upright virtual image. The eyepiece also serves as a light source for illumination.

[0003] The light source is a crucial component in microscope imaging, providing necessary illumination for sample observation. Existing microscope light sources are categorized into conventional light sources and cold light sources. Conventional light sources can be further divided into incandescent lamps, which provide a continuous spectrum but generate a lot of heat and have a short lifespan, and halogen lamps, which provide higher brightness and a longer lifespan than incandescent lamps. Cold light sources are divided into LED lamps, which have advantages such as low heat, long lifespan, and low power consumption and are suitable for various microscopes, and cold light source halogen lamps, which combine the high brightness of halogen lamps with the low-temperature characteristics of LED lamps. However, the housings of existing microscope LEDs are mostly customized for a single LED lamp model. When the LED lamp needs to be replaced, a specific model must be used, which increases the operating cost and reduces maintenance efficiency. Although LED lamps are cold light sources, they still generate a lot of heat after long-term use, making the light source unstable for long-term use, leading to deviations in observation results and reducing practicality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a microscope LED housing structure that improves the stability of the light source. It aims to improve the problem that the existing microscope LED housings are customized for a single LED lamp model, which requires the use of a specific model when the LED lamp needs to be replaced, resulting in increased usage costs and reduced maintenance efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a microscope LED housing structure for improving light source stability, comprising a base, an installation cylinder fixedly connected to the middle of the inner wall of the base, a positioning disk fixedly connected to the outer wall of the installation cylinder, multiple sliding grooves opened at the bottom of the positioning disk, multiple guide grooves opened near the edge of the bottom of the positioning disk, a slider slidably connected to the inner wall of the sliding groove, a rotating disk fixedly connected to the bottom of the slider, multiple positioning grooves opened at the top of the rotating disk, a sliding rod slidably connected to the inner wall of the positioning groove, a fixing sleeve fixedly connected to the middle of the outer wall of the sliding rod, a clamping piece fixedly connected to the adjacent side of the fixing sleeve, a fixing block fixedly connected to the outer wall of the rotating disk, a lead screw threadedly connected to the inner wall of the fixing block, a reinforcing block fixedly connected to the right end of the lead screw, and a cooling mechanism fixedly connected to the bottom of the installation cylinder, the cooling mechanism being used to cool the lamp.

[0006] The above technical solution involves: a base for mounting the entire structure; a sliding groove for guiding the sliding direction of the slider, which in turn guides the rotation direction of the rotating disk; a positioning groove for positioning the sliding direction of the bottom end of the sliding rod; a guide groove for positioning the sliding direction of the bottom end of the sliding rod to prevent it from deviating during sliding; a lead screw that can rotate to move the reinforcing block, thereby pulling the rotating disk to rotate; and a clamping plate for clamping the LED light.

[0007] As a further description of the above technical solution:

[0008] The cooling mechanism includes a cooling plate, the top of which is fixedly connected to the bottom of the mounting cylinder. A heat-conducting plate is fixedly connected to the middle of the inner wall of the mounting cylinder. Multiple heat-conducting blocks are fixedly connected to the inner wall of the heat-conducting plate. Multiple ventilation holes are opened at the bottom of the mounting cylinder near the edge. A filter plate is fixedly connected to the inner wall of the ventilation holes. A metal sheet is fixedly connected to the outer wall of the clamping plate.

[0009] The above technical solution involves: a cooling plate to dissipate heat from the heat-conducting block; a filter plate to ensure ventilation through the vents while preventing external debris from entering the mounting cylinder and damaging the entire structure; and metal sheets to cool the outer wall of the LED.

[0010] As a further description of the above technical solution:

[0011] Multiple heat-conducting blocks are fixedly connected at the same horizontal height, and multiple contact points are fixedly connected to the top of the cooling plate.

[0012] The above technical solution uses contacts to power the LED.

[0013] As a further description of the above technical solution:

[0014] The base has a control plate groove on the top front side, and a first groove is provided on the top of the base near the edge. The left end of the lead screw is fixedly connected to a rotating handle.

[0015] The above technical solution involves a rotating handle to help the user rotate the lead screw, and a control board slot for mounting the control board.

[0016] As a further description of the above technical solution:

[0017] A bracket is fixedly connected to the top rear side of the base, and a second mounting groove is provided on the front side of the bracket.

[0018] The above technical solution involves a support structure used to mount the entire microscope.

[0019] As a further description of the above technical solution:

[0020] The bracket has a first mounting groove in the middle of its front side and a mounting hole near the edge of its front side.

[0021] Through the above technical solution: the first mounting slot is used to insert the remaining structure into it and connect it to the bracket.

[0022] As a further description of the above technical solution:

[0023] A rubber pad is fixedly connected to the bottom of the base, and multiple mounting holes are provided near the edge of the bottom of the base. Multiple third grooves are provided near the edge of the outer wall of the mounting cylinder.

[0024] The above technical solution uses a rubber pad to increase the friction at the bottom of the base.

[0025] As a further description of the above technical solution:

[0026] The bracket has a mounting hole three on its rear side and a second groove in the middle of its rear side.

[0027] Through the above technical solution: the second wire groove is used to guide the wire harness into the bracket.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, by placing the LED light into the mounting cylinder, and then rotating the lead screw to make the fixing block push the rotating disk to rotate, the top of the sliding rod is limited by the guide groove, while its bottom end is driven by the rotation of the rotating disk to slide along the positioning groove, thereby pushing the clamping piece to squeeze inward, thus achieving the purpose of quickly replacing different models of LED lights, reducing the cost of use, and speeding up the maintenance efficiency.

[0030] 2. In this utility model, after the LED light is installed, the heat-conducting plate will contact its bottom, thereby transferring some of the heat from the heat-conducting block to the cooling plate for heat dissipation. At the same time, the metal sheet can dissipate heat from the middle of the outer wall of the LED light, and the ventilation holes can ventilate the inside of the clamping plate for heat dissipation, thus achieving the purpose of stabilizing the light source, improving practicality, and enhancing observation accuracy.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a microscope LED housing structure that improves the stability of the light source. It includes a base 1, with a mounting cylinder 8 fixedly connected to the center of the inner wall of the base 1. The base 1 is used to stably place the entire device. A positioning plate 7 is fixedly connected to the outer wall of the mounting cylinder 8. Multiple sliding grooves 10 are formed at the bottom of the positioning plate 7, and multiple guide grooves 3 are formed near the edge of the bottom of the positioning plate 7. The mounting cylinder 8 is used to mount LED lights. A slider 11 is slidably connected to the inner wall of the sliding groove 10. A rotating disk 12 is fixedly connected to the bottom of the slider 11. Multiple positioning grooves 15 are formed at the top of the rotating disk 12. The sliding groove 10 is... The inner wall of the positioning groove 15 is slidably connected to a sliding rod 13 for guiding the slider 11 to slide within it. A fixing sleeve 14 is fixedly connected to the middle of the outer wall of the sliding rod 13. A clamping piece 9 is fixedly connected to the adjacent side of the fixing sleeve 14.

[0043] Specifically, a clamping piece 9 is fixedly connected to the adjacent side of the fixed sleeve 14, which facilitates the operator to clamp and position the LED light during installation. The reinforcing block 6 is used to limit the lead screw 4 to prevent it from falling off during use. The fixing block 5 can move with the rotation of the lead screw 4, thereby pulling the rotating disk 12 to rotate and driving the entire structure to clamp. The cooling mechanism 2 is used to effectively cool the LED light to ensure that the light source can maintain stable performance during long-term operation.

The ventilation hole 205 is used to ventilate the inner wall of the mounting cylinder 8.

[0045] Specifically, the heat-conducting plate 202 is used to directly contact the bottom of the LED light, thereby guiding some of the heat generated into it. Then, the heat is guided by the heat-conducting block 203 to the cooling plate 201, allowing it to contact the outside environment and quickly dissipate the heat. The filter plate 204 ensures ventilation of the mounting cylinder 8 through the ventilation holes 205, while also preventing external debris and dust from entering the structure and causing a short circuit.

[0046] Please see the appendix Figure 2 - Appendix Figure 4 The top front side of the base 1 has a control plate groove 21, and the top of the base 1 near the edge has a first wire groove 20. The control plate groove 21 is used to install the control panel. The left end of the lead screw 4 is fixedly connected to a rotating handle 23. The bottom of the base 1 is fixedly connected to a rubber pad 22. The first wire groove 20 is used for wire connection. The bottom of the base 1 near the edge has multiple mounting holes 24. The outer wall of the mounting cylinder 8 near the edge has multiple third wire grooves 28. The mounting holes 24 are used to install the structure to the base 1. Multiple heat conducting blocks 203 are fixedly connected at the same horizontal height. The top of the cooling plate 201 is fixedly connected to multiple contacts 27. The rubber pad 22 is used to increase the friction of the bottom of the base 1.

[0047] Specifically, the rotating handle 23 is used to help the user rotate the lead screw 4, the control panel slot 21 is used to install the control panel to control the entire structure, the contact 27 is used to connect to the bottom of the LED light to power it, the mounting hole 24 is used to connect the bottom of the base 1 to the other required structures, the third wire groove 28 and the first wire groove 20 are both used to install the power wires, and the rubber pad 22 is used to increase the friction of the bottom of the base 1.

[0048] Please see the appendix Figure 6 - Appendix Figure 8 A bracket 18 is fixedly connected to the top rear side of the base 1. A second mounting groove 19 is provided on the front side of the bracket 18. The bracket 18 is the top structure that supports the entire microscope. A mounting hole 25 is provided on the rear side of the bracket 18. A second groove 26 is provided in the middle of the rear side of the bracket 18. The mounting hole 25 is used to connect the bracket 18 with the rest of the structure. A first mounting groove 17 is provided in the middle of the front side of the bracket 18. A mounting hole 16 is provided near the edge of the front side of the bracket 18. The first mounting groove 17 is used to engage the rest of the structure with the bracket 18.

[0049] Specifically, the bracket 18 is used to support and mount the rest of the microscope's structure. The first mounting slot 17 can engage the required structure with it. Mounting holes 25 and 16 are used to thread the bracket 18 and the rest of the structure. The second groove 26 is used to guide the power supply beam from the rear into the interior of the entire mechanism. The second mounting slot 19 can mount the stage, on which a slide is placed for easy observation by the user.

[0050] Working principle: When different LED lights need to be installed, they are first placed in the mounting cylinder 8. Then, the screw 4 is rotated so that the fixing block 5 can move on it, thereby pushing the rotating disk 12 to rotate, so that the slider 11 slides in the sliding groove 10. At the same time, the top end of the sliding rod 13 is limited in the guide groove 3, while the bottom end of the sliding rod 13 is driven to slide along the positioning groove 15 by the rotation of the rotating disk 12, thereby pushing the clamping piece 9 to move inward to clamp the LED light. The second mounting groove 19 is used to install the stage, and the stage is used to place the glass slide.

[0051] After the LED light is installed, its bottom contacts the heat conduction plate 202, so that the heat generated when it emits light is conducted by the heat conduction plate 202 into the heat conduction block 203, and then conducted along the heat conduction block 203 into the cooling plate 201. At the same time, the metal sheet 206 is attached to the outer wall of the LED light, so that it can absorb and conduct the heat generated by its outer wall. Meanwhile, the ventilation hole 205 ventilates and dissipates heat on the inside of the mounting cylinder 8, and the filter plate 204 ensures that when the ventilation hole 205 dissipates heat, external dust will not be introduced into it and cause a short circuit.

[0052] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
