Description

Technical Field

[0001] The utility model relates to the technical field of optical imaging, and particularly relates to an optical imaging device. Background Art

[0002] Light is everywhere around us, and optical imaging technology is also closely related to our lives. For example, various cameras, video cameras, telescopes, projectors, etc. In most of the refraction or reflection type optical imaging systems used in daily life, virtual images of light sources or objects are presented. Therefore, it is necessary to image on a specific screen or flat object. The optical system consists of a series of refraction and reflection surfaces (usually spherical, and there are also flat and aspherical surfaces). If their centers of curvature are on the same straight line, then the optical system is called a coaxial optical system, and this straight line is called the optical axis.

[0003] A Chinese utility model patent with the publication number CN214586250U discloses an optical imaging display device, which includes a base, a lens and an imaging plate. An adjusting mechanism is arranged on the front of the top of the base, a fixing seat is arranged on the adjusting mechanism, and the imaging object is placed on the fixing seat. The adjusting mechanism adjusts the height of the imaging object, and it is convenient to observe the imaging effect during adjustment, and the operation is simple and fast.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: when the above device is in use, only the imaging object is placed on the fixing seat, which is relatively unstable. When the staff accidentally touches the device during the operation, it is easy to cause the imaging object to fall off the fixing seat. Moreover, after the imaging object is placed on the fixing seat, only one angle of the imaging object can be observed. When it is necessary to observe other angles of the imaging object, the imaging object needs to be manually moved, which is inaccurate and not convenient for continuous observation. Summary of the Utility Model

[0005] In order to solve the above problems, the utility model provides an optical imaging device.

The placement table includes a fixed square tube provided on the first sliding seat, a third sliding seat is vertically slidably provided in the fixed square tube, and a driving assembly for driving the third sliding seat to slide is further provided in the fixed square tube. A plurality of support columns are provided on the top of the third sliding seat, and a top plate is jointly provided on the tops of the plurality of support columns. Mounting plates are provided on both sides of the top plate, two sliding rods are provided between the two mounting plates, the length direction of the sliding rods is perpendicular to the length direction of the chute, two sliding blocks are jointly slidably provided on the two sliding rods, a bidirectional screw is rotatably provided between the two mounting plates, the sliding blocks are in screw fit with the bidirectional screw through threaded holes, a vertical plate is vertically provided on the sliding blocks, a sliding plate is vertically slidably provided on the vertical plate, a lifting assembly for driving the sliding plate to lift is provided on the third sliding seat, and clamping plates are rotatably provided on the sliding plate, and the two clamping plates are arranged oppositely.

[0007] By adopting the above technical solutions, the base, the first sliding seat, the second sliding seat, the imaging plate, the placement table and the lens are provided. The imaging object is placed on the top plate. The bidirectional screw is rotated to make the sliding blocks slide towards the middle of the top plate along the sliding rods until the two clamping plates clamp the imaging object, ensuring the stable placement of the imaging object. Then, the lifting assembly is used to drive the sliding plate to rise, so that the clamping plates clamp the imaging object and rise. Then, the driving assembly is used to drive the third sliding seat to slide until the imaging object, the lens and the imaging plate are in a straight line. Then, the first sliding seat is slid to adjust the distance between the imaging object and the lens for convenient imaging, and the second sliding seat is slid to adjust the distance between the imaging plate and the lens for convenient observation of the dynamic change of the imaging. The clamping plates are rotated to drive the imaging object to rotate, which is convenient for observing other angles of the imaging object. It can be rotated while observing, which is more convenient for continuous observation.

[0008] Further, a rotating shaft is provided on the sliding plate, and the clamping plate is arranged on the rotating shaft. A fixing ring arranged concentrically with the rotating shaft is provided on one side of the sliding plate away from the clamping plate. The vertical plate is provided with an avoidance hole corresponding to the fixing ring. A plurality of fixing holes are circumferentially spaced apart on the side of the fixing ring away from the sliding plate. One end of the rotating shaft passes through the sliding plate and is placed inside the fixing ring. A square rod is provided at the end of the rotating shaft away from the clamping plate. A sliding ring is slidably arranged on the square rod. A fixing rod is provided on the sliding ring and is placed in the fixing hole. A baffle is provided at the end of the square rod away from the rotating shaft. A compression spring is sleeved on the rod body of the square rod between the baffle and the sliding ring. One end of the compression spring is connected to the baffle and the other end is connected to the sliding ring.

[0009] By adopting the above technical solution, the rotating shaft, the fixing ring, the avoidance hole, the fixing hole, the square rod, the sliding ring, the fixing rod, the baffle and the compression spring are provided. The sliding ring is slid outwards so that the fixing rod is disengaged from the fixing hole, and then the sliding ring is rotated to drive the square rod, the rotating shaft and the clamping plate to rotate, thereby driving the imaging article to rotate. When the sliding ring is slid outwards, the compression spring is compressed. When it is rotated to a suitable position, the sliding ring is slid towards the fixing ring so that the fixing rod is inserted into the fixing hole, thereby fixing the square rod, the rotating shaft and the clamping plate, which is convenient for observing the imaging article; the compression spring is used to tightly press the sliding ring towards the fixing ring to prevent the sliding ring from sliding outwards under non-human force, so that the fixing rod is disengaged from the fixing hole.

[0010] Further, the lifting assembly includes a threaded rod rotatably arranged on the top of the third sliding seat. A lifting block is spirally arranged on the threaded rod. Lifting rods horizontally arranged are suspended on both sides of the lifting block. A strip-shaped hole with a length direction consistent with the length direction of the sliding rod is provided on the top plate. Two vertically arranged sliding rods are slidably arranged in the strip-shaped hole. The tops of the two sliding rods are respectively connected to the bottoms of the two sliding plates, and the bottoms are respectively slidably arranged on the two lifting rods. A power unit for driving the threaded rod to rotate is further provided on the third sliding seat.

[0011] By adopting the above technical solution, the threaded rod, the lifting block, the lifting rod, the strip-shaped hole, the sliding rod and the power unit are provided. The power unit drives the threaded rod to rotate. Since the lifting block is restricted by the lifting rod and the sliding rod and cannot rotate, the lifting block can only lift. The lifting of the lifting block drives the lifting rod to lift, thereby driving the sliding plate and the clamping plate to lift; the bottoms of the sliding rods are respectively slidably arranged on the two lifting rods. When the sliding block slides, the sliding rod slides on the lifting rod, so that the sliding rod is always connected to the lifting rod. Thus, when the sliding block is in any position, the power unit can still drive the sliding plate to lift.

[0012] Further, the power unit includes a worm gear concentrically arranged at the lower end of the threaded rod. A worm is rotatably arranged on the third sliding seat. The worm gear is engaged with the worm.

[0013] By adopting the above technical solution, a worm gear and a worm are provided. Rotating the worm gear drives the worm to rotate, thereby driving the threaded rod to rotate. Since the worm and worm gear transmission can only transmit power in one direction, the stability of the lifting position of the sliding plate is ensured.

[0014] Furthermore, a plurality of first sliding rails are arranged at intervals in the fixed square tube, and the third sliding seat is slidably arranged on the first sliding rails through sliders.

[0015] By adopting the above technical solution, the third sliding seat is slidably arranged on the first sliding rails through sliders, ensuring the stability of the sliding of the third sliding seat.

[0016] Furthermore, the driving assembly includes a rack vertically arranged on the third sliding seat, a driving motor horizontally arranged in the fixed square tube, and a driving wheel arranged on the output shaft of the driving motor, and the driving wheel meshes with the rack.

[0017] By adopting the above technical solution, a rack, a driving motor, and a driving wheel are provided. The driving motor drives the driving wheel to rotate, so that the rack and the third sliding seat slide up and down along the first sliding rails.

[0018] Furthermore, a second sliding rail is arranged on the vertical plate, and the sliding plate is slidably arranged on the second sliding rail through a slider.

[0019] By adopting the above technical solution, the sliding plate is slidably arranged on the second sliding rail through a slider, ensuring the stability of the sliding of the sliding plate.

[0020] Furthermore, two electric telescopic rods are arranged in the middle of the sliding groove. The orientations of the two electric telescopic rods are opposite. The telescopic rod of one electric telescopic rod is connected to the first sliding seat, and the telescopic rod of the other electric telescopic rod is connected to the second sliding seat.

[0021] By adopting the above technical solution, two electric telescopic rods are arranged in the middle of the sliding groove. By respectively controlling the first sliding seat and the second sliding seat through the two electric telescopic rods, it is more convenient and ensures the stability of the sliding of the first sliding seat and the second sliding seat.

[0022] In summary, the utility model has the following beneficial effects: In this application, a base, a first sliding seat, a second sliding seat, an imaging plate, a placement table, and a lens are provided. The imaging object is placed on the top plate, and the bidirectional screw is rotated, causing the sliding block to slide along the slide bar towards the middle of the top plate until the two clamping plates clamp the imaging object, ensuring the stable placement of the imaging object. Then, the lifting assembly drives the sliding plate to rise, so that the clamping plate clamps the imaging object and rises. Then, the driving assembly drives the third sliding seat to slide until the imaging object, the lens, and the imaging plate are in a straight line. Then, the first sliding seat is slid to adjust the distance between the imaging object and the lens for convenient imaging, and the second sliding seat is slid to adjust the distance between the imaging plate and the lens for convenient observation of the dynamic changes of the imaging.

Detailed implementation mode

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] As Figure 1-6 shown, the embodiment of the present application discloses an optical imaging device, including a base 10, a first sliding seat 12, a second sliding seat 13, an imaging plate 14, a placement table 20, and a lens 15. A chute 11 is opened on the base 10 along its length direction. The first sliding seat 12 and the second sliding seat 13 are respectively slidably arranged on both sides inside the chute 11. The imaging plate 14 is arranged on the second sliding seat 13, and the placement table 20 is arranged on the first sliding seat 12, so that the imaging plate 14 and the placement table 20 can slide along the chute 11. The lens 15 is arranged on the base 10 between the imaging plate 14 and the placement table 20. Slide the first sliding seat 12 to adjust the distance between the imaging object and the lens 15 for convenient imaging. Slide the second sliding seat 13 to adjust the distance between the imaging plate 14 and the lens 15 for convenient observation of the dynamic changes of the imaging.

[0032] Specifically, the placing table 20 includes a fixed square tube 21 disposed on the first sliding seat 12. A third sliding seat 22 is vertically slidably disposed within the fixed square tube 21. A number of first sliding rails 211 are spaced apart within the fixed square tube 21. The third sliding seat 22 is slidably disposed on the first sliding rails 211 through sliders, ensuring the stability of the sliding of the third sliding seat 22. A driving assembly 30 is further disposed within the fixed square tube 21 for driving the third sliding seat 22 to slide. The driving assembly 30 includes a rack 31 vertically disposed on the third sliding seat 22. A driving motor 32 is horizontally disposed within the fixed square tube 21. A driving wheel 33 is disposed on the output shaft of the driving motor 32. The driving wheel 33 meshes with the rack 31. The driving motor 32 drives the driving wheel 33 to rotate, so that the rack 31 and the third sliding seat 22 slide up and down along the first sliding rails 211.

[0033] During installation, a number of support columns 221 are disposed on the top of the third sliding seat 22. A top plate 23 is commonly disposed on the tops of the number of support columns 221, so that the top plate 23 is stably installed on the third sliding seat 22. The length direction of the top plate 23 is perpendicular to the length direction of the base 10. Mounting plates 24 are disposed on both sides in the length direction of the top plate 23. The length direction of the mounting plates 24 is perpendicular to the length direction of the top plate 23. The upper edges of the mounting plates 24 are flush with the upper edge of the top plate 23. The length of the mounting plates 24 is greater than the width of the top plate 23. Two slide bars 241 are disposed between the two mounting plates 24. The two slide bars 241 are respectively disposed on both sides of the mounting plates 24. The length direction of the slide bars 241 is perpendicular to the length direction of the sliding groove 11. Two sliding blocks 26 are commonly slidably disposed on the two slide bars 241. The two sliding blocks 26 are respectively disposed on both sides of the slide bars 241, so that the sliding blocks 26 can slide along the slide bars 241. A bidirectional screw 242 is rotatably disposed between the two mounting plates 24. The sliding blocks 26 are in screw fit with the bidirectional screw 242 through threaded holes. The rotation of the bidirectional screw 242 drives the sliding blocks 26 to slide towards the middle of the top plate 23 or slide away from each other towards the middle of the top. A vertical plate 27 is vertically disposed on the sliding block 26. A sliding plate 28 is vertically slidably disposed on the vertical plate 27. A second sliding rail 272 is disposed on the vertical plate 27. The sliding plate 28 is slidably disposed on the second sliding rail 272 through a slider, ensuring the stability of the sliding of the sliding plate 28. A lifting assembly 40 for driving the sliding plate 28 to lift is disposed on the third sliding seat 22.

[0034] The lifting assembly 40 includes a threaded rod 41 rotatably arranged on the top of the third sliding seat 22. A lifting block 42 is spirally arranged on the threaded rod 41. Lifting rods 43 arranged horizontally are cantilevered on both sides of the lifting block 42. A strip-shaped hole 231 with the same length direction as the length direction of the sliding rod 241 is formed in the top plate 23. Two vertically arranged sliding rods 44 are slidably arranged in the strip-shaped hole 231. The tops of the two sliding rods 44 are respectively connected to the bottoms of the two sliding plates 28, and the bottoms are respectively slidably arranged on the two lifting rods 43. When the threaded rod 41 rotates, since the lifting block 42 is restricted by the lifting rods 43 and the sliding rods 44 and cannot rotate, the lifting block 42 can only move up and down. The lifting of the lifting block 42 drives the lifting of the lifting rods 43, thereby driving the lifting of the sliding plates 28 and the clamping plates 29. And the bottoms of the sliding rods 44 are respectively slidably arranged on the two lifting rods 43. When the sliding block 26 slides, the sliding rods 44 slide on the lifting rods 43, so that the sliding rods 44 are always connected to the lifting rods 43. Thus, when the sliding block 26 is in any position, the threaded rod 41 can still drive the sliding plate 28 to lift. A power unit 50 is further arranged on the third sliding seat 22 for driving the rotation of the threaded rod 41.

[0035] The power unit 50 includes a worm gear 51 concentrically arranged at the lower end of the threaded rod 41. A worm 52 is rotatably arranged on the third sliding seat 22. The worm gear 51 cooperates with the worm 52. Rotating the worm gear 51 drives the worm 52 to rotate, thereby driving the rotation of the threaded rod 41. Since the transmission between the worm 52 and the worm gear 51 can only be one-way transmission, the stability of the lifting position of the sliding plate 28 is ensured.

[0036] A clamping plate 29 is rotatably arranged on the sliding plate 28, and two clamping plates 29 are arranged opposite to each other. In the specific arrangement, a rotating shaft 281 is arranged on the sliding plate 28, and the clamping plate 29 is arranged on the rotating shaft 281, so that the clamping plate 29 can rotate stably. The imaging object is placed on the top plate 23, and the bidirectional screw 242 is rotated so that the sliding block 26 slides along the sliding rod 241 toward the middle of the top plate 23, so that the two clamping plates 29 clamp the imaging object to ensure the stability of the imaging object. A fixing ring 282 arranged coaxially with the rotating shaft 281 is arranged on the side of one of the sliding plates 28 away from the clamping plate 29, and a plurality of fixing holes 283 are circumferentially spaced apart on the side of the fixing ring 282 away from the sliding plate 28, one end of the rotating shaft 281 passes through the sliding plate 28 and is placed in the fixing ring 282, and a square rod 284 is arranged on the end of the rotating shaft 281 away from the clamping plate 29, so that the rotating shaft 281, the clamping plate 29, and the square rod 284 rotate synchronously. A sliding ring 285 is slidably provided on the square rod 284. The sliding ring 285 slides on the square rod 284 and is slidably provided on the square rod 284 through a square hole, so that the sliding ring 285 and the square rod 284 rotate synchronously. A fixing rod 286 is provided on the sliding ring 285, and the fixing rod 286 is placed in the fixing hole 283, so that the sliding ring 285 is fixed, thereby fixing the rotating shaft 281, the square rod 284, and the clamping plate 29. The sliding plate 28 is driven to rise by the lifting assembly 40, and then the driving assembly 30 is used to drive the third sliding seat 22 to slide until the imaging object, the lens 15, and the imaging plate 14 are in a straight line, and then the sliding ring 285 is slid outward to make the fixing rod 286 disengage from the fixing hole 283, and then the sliding ring 285 is rotated to drive the square rod 284, the rotating shaft 281, and the clamping plate 29 to rotate, thereby driving the imaging object to rotate. When it is rotated to a suitable position, the sliding ring 285 is slid toward the fixing ring 282, so that the fixing rod 286 is inserted into the fixing hole 283, so that the square rod 284, the rotating shaft 281, and the clamping plate 29 are fixed, so that other angles of the imaging object can be observed, and it can be rotated while observing, which is more convenient for continuous observation.

[0037] A baffle 287 is provided at one end of the square rod 284 away from the rotating shaft 281, and a compression spring 288 is sleeved on the rod body of the square rod 284 between the baffle 287 and the sliding ring 285. One end of the compression spring 288 is connected to the baffle 287 and the other end is connected to the sliding ring 285. When the sliding ring 285 slides outward, the compression spring 288 is compressed, and the sliding ring 285 is pressed against the fixed ring 282 by the compression spring 288 to prevent the sliding ring 285 from sliding outward without human power, thereby causing the fixed rod 286 to be separated from the fixed hole 283. The vertical plate 27 is provided with an avoidance hole 271 corresponding to the fixed ring 282. When the sliding plate 28 is raised and lowered to drive the fixed ring 282 to rise and fall, the avoidance hole 271 avoids the fixed ring 282 to avoid interference.

[0038] Two electric telescopic rods 16 are arranged in the middle of the sliding groove 11. The two electric telescopic rods 16 face in opposite directions. The telescopic rod of one electric telescopic rod 16 is connected to the first sliding seat 12, and the telescopic rod of the other electric telescopic rod 16 is connected to the second sliding seat 13. The first sliding seat 12 and the second sliding seat 13 are controlled by the two electric telescopic rods 16 respectively, which is more convenient and ensures the stability of the sliding of the first sliding seat 12 and the second sliding seat 13.

[0039] In this embodiment, the working principle of an optical imaging device is as follows: Place the imaging object on the top plate 23, rotate the bidirectional screw rod 242, so that the sliding block 26 slides along the slide rod 241 towards the middle of the top plate 23 until the two clamping plates 29 clamp the imaging object. Then rotate the worm gear 51 to drive the worm 52 to rotate, thereby driving the threaded rod 41 to rotate, so that the lifting block 42 rises. The rising of the lifting block 42 drives the lifting rod 43, the lifting plate and the clamping plate 29 to rise, so that the clamping plate 29 clamps the imaging object and rises. Then start the driving motor 32 to drive the driving wheel 33 to rotate, so that the rack 31 and the third sliding seat 22 rise along the first slide rail 211 until the imaging object, the lens 15 and the imaging plate 14 are in a straight line. The first sliding seat 12 and the second sliding seat 13 are driven to slide by the two electric telescopic rods 16, so as to adjust the distance between the imaging plate 14, the imaging object and the lens 15, which is convenient for observing the dynamic changes of the imaging. Slide the sliding ring 285 outwards so that the fixing rod 286 disengages from the fixing hole 283, and then rotate the sliding ring 285 to drive the square rod 284, the rotating shaft 281 and the clamping plate 29 to rotate, thereby driving the imaging object to rotate, which is convenient for observing other angles of the imaging object. It can be rotated while observing, which is more convenient for continuous observation.

All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
