Description

A position-adjustable microscope lamp source device Technical Field

[0001] This invention relates to the field of microscope auxiliary lighting technology, and more particularly to a microscope lamp source device with adjustable position. Background Technology

[0002] As a precision observation instrument, the stability and adaptability of the illumination system of a microscope directly affect the observation accuracy. Most existing microscope lamp source devices adopt a rigid connection mode of fixed base-lamp arm-lamp head. Specifically, the fixed base is fastened to the preset mounting holes of the microscope arm with bolts, the lamp arm is an integrated bent metal rod, the lamp head is fixed to the end of the lamp arm with threads or buckles, and the lamp source (mostly LED beads) is embedded in the lamp head with a fixed emission angle.

[0003] However, existing microscope lamp source devices lack sufficient freedom of position adjustment during use. Due to the rigid structure of the lamp arm, horizontal rotation adjustment of the entire lamp arm can only be achieved by loosening the fixing bolts, or limited pitch adjustment can be achieved through the connection between the lamp head and the lamp arm. Forward and backward translation of the lamp source along the microscope's optical axis is not possible. Furthermore, the adjustment precision is low and stability is poor. The adjustment process requires manually loosening the bolts and then tightening them again after adjustment, which is cumbersome and prone to lamp source displacement due to uneven bolt tightening. Especially in high-magnification observation scenarios, even slight lamp source displacement can cause the illuminated area to shift, affecting observation clarity. Secondly, adaptability is limited. The fixed length of the lamp arm in existing lamp source devices cannot adapt to the illumination requirements of different objective lens focal lengths. For short focal length objectives, the lamp source easily obstructs the field of view; for long focal length objectives, it is difficult to ensure uniform illumination intensity covering the observation area, making it difficult to accurately adapt to the height requirements of different stage sizes (such as single-layer stages and double-layer lifting stages). Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the existing technology. The present invention proposes a microscope lamp source device with adjustable position.

[0005] To address the insufficient degree of freedom in position adjustment of existing microscope lamp source devices, the following solutions are proposed. Due to the rigid structure of the lamp arm, horizontal rotation adjustment of the entire lamp arm can only be achieved by loosening the fixing bolts, or limited pitch adjustment can be achieved through the connection between the lamp head and the lamp arm. Forward and backward translation of the lamp source along the microscope's optical axis is not possible. Furthermore, the adjustment accuracy is low and stability is poor. The adjustment process requires manually loosening the bolts and then tightening them after adjustment, which is cumbersome and prone to lamp source displacement due to uneven bolt tightening. Especially in high-magnification observation scenarios, even slight lamp source displacement can cause the illuminated area to shift, affecting observation clarity. Secondly, the adaptability is limited. Existing lamp source devices have a fixed lamp arm length, which cannot adapt to the illumination requirements of different objective lens focal lengths. For short focal length objectives, the lamp source easily obstructs the observation field of view, while for long focal length objectives, it is difficult to ensure uniform illumination intensity covering the observation area. This leads to the technical problem of not being able to accurately adapt to the height requirements of different stage sizes. The technical solution adopted in this invention is: a position-adjustable microscope lamp source device, including: a microscope body and a microscope lamp head; a lamp source mounting base, which is vertically slidably disposed on the upper end of the microscope body; a vertical transmission mechanism, which is drivenly connected to the lamp source mounting base for driving the lamp source mounting base to move vertically and linearly for adjustment; and an extension frame, which is set on... An adjustment seat is horizontally slidably mounted on the front end of the lamp source mounting base and the front end of the extension frame; a horizontal transmission mechanism is driven to the adjustment seat and is used to drive the adjustment seat to move linearly back and forth; a first adjustment frame is rotatably mounted on the front end of the adjustment seat, and a second adjustment frame is rotatably mounted on the front end of the first adjustment frame and the microscope lamp head is mounted on the front end of the second adjustment frame, which is used to synchronously drive the microscope lamp head to swing left and right and up and down; a first adjustment group and a second adjustment group are driven to the first adjustment frame and the second adjustment frame respectively, and are used to drive the first adjustment frame and the second adjustment frame to rotate left and right and up and down.

[0006] Preferably, the vertical transmission mechanism includes a first motor and a first lead screw. The first motor is disposed at the upper end of the microscope body, the first lead screw is partially connected to the transmission shaft of the first motor, and the first lead screw is vertically threadedly connected to the middle of the lamp source mounting base.

[0007] Preferably, a slide rail is provided on the rear side of the connecting seat, a slide block is slidably connected to the front end of the slide rail, and the lamp source mounting seat is provided at the front end of the slide block. A top plate is provided on the top of the slide rail, and the first lead screw is rotatably connected to the middle of the lower end of the top plate.

[0008] Preferably, the horizontal transmission mechanism includes a second motor, a second lead screw, and an internally threaded tube. The second motor is located at the front end of the extension frame. The second lead screw is connected to the front drive shaft of the second motor and is rotatably connected to the front end of the extension frame. The internally threaded tube is disposed through the middle of the adjusting seat, and the second lead screw is threadedly connected to the inner wall of the internally threaded tube.

[0009] Preferably, a sliding rod is slidably connected through the middle of the extension frame, a sliding groove is provided on the outer side of the extension frame, a slider is slidably connected inside the sliding groove, a telescopic arm is provided at the outer end of the slider, and an adjustment seat is provided at the front end of the telescopic arm.

[0010] Preferably, the first adjustment group includes a first adjustment knob, a first gear, a second gear, and a third gear. The first adjustment knob is rotatably disposed on the upper end of the adjustment seat. The first gear is coaxially disposed on the lower end of the first adjustment knob. The second gear is meshed with the side end of the first gear. The third gear is coaxially mounted on the upper end of the second gear. The side end of the third gear is meshed with a first gear disc.

[0011] Preferably, the second gear is rotatably connected to the upper end of the adjusting seat, and the first gear plate is located on the rear side of the upper end of the first adjusting frame.

[0012] Preferably, the second adjustment group includes a second adjustment knob, a fourth gear, a fifth gear, and a sixth gear. The second adjustment knob is rotatably disposed on the side end of the first adjustment frame. The fourth gear is coaxially disposed inside the second adjustment knob.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: By activating a first motor, the first motor drives a first lead screw to rotate. Since the first lead screw is threadedly connected to the center of the lamp source mounting base, the force generated during rotation causes the lamp source mounting base to move vertically. When the lamp source mounting base moves, it causes the extension frame to move vertically along the outer curved surface of the slide rod, thereby synchronously causing the microscope lamp head to move vertically, achieving vertical adjustment of the LED lamp source position. By activating a second motor, the second motor drives a second lead screw to rotate. The second lead screw is threadedly connected to an internally threaded pipe, and the force generated during rotation causes an adjusting seat to move back and forth linearly. When the adjusting seat moves, it synchronously causes the lamp source mounting base to move back and forth linearly, thus achieving both vertical and horizontal adjustment of the LED lamp source position and horizontal adjustment of the illumination position.

[0016] This invention also achieves multi-directional adjustment of the microscope lamp head by rotating a first adjustment knob. The first adjustment knob drives a first gear to rotate, which in turn drives a second gear to rotate. The second gear drives a third gear to rotate, which in turn drives a first geared disc to rotate. The first geared disc simultaneously drives a first adjustment frame to swing left and right, thereby simultaneously adjusting the microscope lamp head to swing left and right. By rotating a second adjustment knob, the second adjustment knob drives a fourth gear to rotate, which in turn drives a fifth gear to rotate. The fifth gear drives a sixth gear to rotate, which in turn drives a second geared disc to rotate. The second geared disc simultaneously drives a second adjustment frame to swing up and down, thereby adjusting the microscope lamp head to swing up and down. Through these operations, multi-directional adjustment of the microscope lamp head can be achieved, meeting the lighting needs of different observation scenarios. Furthermore, the lead screw and multi-gear transmission structure enables precise adjustment of the microscope lamp head. Attached Figure Description

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0020] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0021] Referring to Figures 1-5, this embodiment proposes a position-adjustable microscope lamp source device, which comprises a microscope body 1, a lamp source mounting base 2, and a microscope lamp head 3. The microscope body 1 includes an upper microscope part 101, a lower microscope part 102, and a connecting base 103. The upper microscope part 101 and the lower microscope part 102 are respectively mounted on the upper and lower ends of the connecting base 103, achieving installation and connection between them. The lower end of the microscope lamp head 3 has a light source annular groove 301, and several adjustable brightness LED beads 302 are adhered to the inner top of the light source annular groove 301 for supplemental lighting of the microscope body 1.

[0022] Two slide rails 4 are screwed onto the rear side of the connecting seat 103. These two slide rails 4 are vertically and symmetrically distributed on the rear side of the upper end of the microscope body 1. A slide block 5 is slidably connected to the front end of the slide rail 4. The lamp source mounting seat 2 is screwed onto the front end of the slide block 5. With the cooperation of the slide rail 4 and the slide block 5, the lamp source mounting seat 2 is vertically limited in its sliding direction. A top plate 6 is screwed onto the top of the slide rail 4. A first lead screw 7 is rotatably connected to the middle of the lower end of the top plate 6 via a rotating shaft. The first lead screw 7 is vertically threadedly connected to the middle of the lamp source mounting seat 2. A first motor 17 is embedded in the middle of the lower end of the connecting seat 103. The upper drive shaft of the first motor 17 is connected to the first lead screw 7 via a key.

[0023] An extension frame 8 is screwed onto the front end of the lamp source mounting base 2. A slide rod 9 is slidably connected through the middle of the extension frame 8. The slide rod 9 is vertically mounted to the rear ends of the upper part 101 and the lower part 102 of the microscope, and the slide rod 9 limits the vertical sliding of the extension frame 8. Two sliding grooves 10 are formed on the outer side of the extension frame 8, and these two sliding grooves 10 are horizontally symmetrically distributed. A slider 11 is slidably connected inside the sliding groove 10. A telescopic arm 12 is screwed onto the outer end of the slider 11, and the sliding grooves 10 and the slider 11 limit the horizontal sliding of the telescopic arm 12. An adjusting seat 13 is mounted on the front end of the telescopic arm 12, and the telescopic arm 12 provides horizontal sliding support for the adjusting seat 13. A second motor 14 is mounted on the front end of the extension frame 8. A second lead screw 15 is keyed to the front drive shaft of the second motor 14, and the second lead screw 15 is rotatably connected to the front end of the extension frame 8 via a rotating shaft. An internally threaded tube 16 is bonded through the middle of the adjusting seat 13, and the second lead screw 15 is threaded to the inner wall of the internally threaded tube 16.

[0024] The front end of the adjusting seat 13 is rotatably connected to a first adjusting frame 1301 via a damping shaft. The front end of the first adjusting frame 1301 is rotatably connected to a second adjusting frame 1302 via a damping shaft. The microscope lamp head 3 is mounted on the front end of the second adjusting frame 1302 via screws. The upper end of the adjusting seat 13 is rotatably connected to a first adjusting knob 1303 via a damping shaft. The lower end of the first adjusting knob 1303 is coaxially fitted with a first gear 1304. The side end of the first gear 1304 is meshed with a second gear 1305. The second gear 1305 is rotatably connected to the upper end of the adjusting seat 13 via a damping shaft. The upper end of the second gear 1305 is coaxially fitted with a third gear 1306. The side end of the third gear 1306 is meshed with a first gear disc 1307. The first gear disc 1307 is bonded to the rear side of the upper end of the first adjusting frame 1301. By rotating the first adjusting knob 1303, the first adjusting frame 1301 can be sequentially engaged and driven to swing left and right for adjustment. A second adjusting knob 1308 is rotatably connected to the side end of the first adjusting frame 1301 via a damping shaft. A fourth gear 1309 is coaxially mounted on the inner side of the second adjusting knob 1308. The upper end of the fourth gear 1309 is meshed with a fifth gear 1310, which is rotatably connected to the side end of the first adjusting frame 1301 via a damping shaft. A sixth gear 1311 is coaxially mounted to the side end of the fifth gear 1310. The lower end of the sixth gear 1311 is meshed with a second gear disc 1312, which is bonded to the side end of the second adjusting frame 1302. By rotating the second adjusting knob 1308, the second adjusting frame 1302 can be adjusted up and down by sequentially engaging the gears.

[0025] Please refer to Figures 1-5. In this embodiment, when in use, turning on the LED bead 302 provides supplemental lighting for the microscope body 1. When it is necessary to adjust the position of the LED bead 302, the first motor 17 is turned on, which drives the first lead screw 7 to rotate. Since the first lead screw 7 is threadedly connected to the center of the lamp source mounting base 2, the force generated during rotation will cause the lamp source mounting base 2 to move vertically. When the lamp source mounting base 2 moves, it will cause the extension frame 8 to move vertically along the outer curved surface of the slide rod 9, thereby synchronously driving the microscope lamp head 3 to move vertically, realizing the vertical adjustment of the position of the LED bead 302.

[0026] The second motor 14 is turned on, which drives the second lead screw 15 to rotate. The second lead screw 15 is threadedly connected to the internal threaded tube 16. The force generated when it rotates will cause the adjusting seat 13 to move back and forth linearly. When the adjusting seat 13 moves, it will simultaneously drive the lamp source mounting seat 2 to move back and forth linearly, so that while the LED lamp bead 302 can be adjusted up and down linearly, the lighting position can also be adjusted back and forth linearly.

[0027] Rotating the first adjustment knob 1303 causes the first gear 1304 to rotate, which in turn drives the second gear 1305 to rotate. The second gear 1305 then drives the third gear 1306 to rotate, which in turn drives the first gear 1307 to rotate. The first gear 1307 then drives the first adjustment frame 1301 to swing left and right, which in turn drives the microscope lamp head 3 to swing left and right for adjustment.

[0028] Rotating the second adjustment knob 1308 causes the fourth gear 1309 to rotate, which in turn drives the fifth gear 1310 to rotate. The fifth gear 1310 then drives the sixth gear 1311 to rotate, which in turn drives the second gear 1312 to rotate. The second gear 1312 simultaneously drives the second adjustment bracket 1302 to swing up and down, thereby causing the microscope lamp head 3 to swing up and down for adjustment. Through the above operations, multi-directional adjustment of the microscope lamp head 3 can be achieved to meet the lighting needs of different observation scenarios. At the same time, the precise adjustment of the microscope lamp head 3 can be achieved by means of the lead screw and multi-gear transmission structure.

[0029] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
