Description

Technical Field

[0001] This application relates to the field of microscope technology, and more specifically, to a microscope stand. Background Technology

[0002] Microscopes can be used to observe PCBs, displays, semiconductor chips, etc. To make microscope observation more convenient, microscopes are often mounted on lifting stands.

[0003] In response, Chinese patent application number CN202322464647.7 discloses a microscope lifting support. This solution mainly achieves the change of observation position of the microscope fixing ring in the left and right directions by loosening the first limiting nut, which can rotate in the strip groove; by loosening the second limiting nut, the microscope fixing ring rotates around the second threaded rod as an axis, which achieves the change of angle of the microscope fixing ring in the up and down directions, and the microscope can be directly pulled to observe different slides directly.

[0004] However, in the process of implementing the technical solutions in the embodiments of this application, the inventors of this utility model discovered that the above-mentioned technology has at least the following technical problems:

[0005] By adjusting the lifting bracket, the microscope can be directly pulled to observe different slides. During observation, fine adjustments are required in all directions. However, the lifting bracket mentioned above is adjusted by hinges, which makes it difficult to achieve fine adjustments and the adjustment is not precise enough. Utility Model Content

[0006] To overcome the above deficiencies, this application provides a microscope stand designed to improve the problems mentioned in the background art.

[0007] This application provides a microscope stand, including a base, a fine-tuning mechanism at the rear end of the base, a mounting bracket on the fine-tuning mechanism, a sliding plate slidably connected to the front end of the base, an adsorption mechanism on the base adsorbingly connected to the sliding plate, and a guide frame between the sliding plate and the base.

[0008] In one specific implementation, the fine-tuning mechanism includes a slide block that is slidably connected to the base, and a slider is slidably connected to the slide block.

[0009] In the above implementation process, the sliding directions of the slider and the slide block are perpendicular to each other, thereby achieving free horizontal movement.

[0010] In one specific implementation, both the base and the slide are rotatably connected to lead screws, and the two lead screws are respectively screwed to the slide and the slider, with a throttle fixedly connected to each lead screw.

[0011] In the above process, the throttle is turned to control the rotation of the two lead screws respectively, thereby driving the slide and slider to make fine adjustments in the horizontal direction.

[0012] In one specific implementation, the mounting bracket includes a lifting bracket and a mounting ring. The lower end of the lifting bracket is fixedly connected to the slider, and the upper end of the lifting bracket is fixedly connected to the mounting ring. The mounting ring is provided with locking screws.

[0013] In the above implementation process, the lifting support adopts a conventional screw lifting mechanism, which will not be described in detail here, to achieve fine adjustment in the vertical direction.

[0014] In one specific implementation, the guide frame includes vertical bars and horizontal bars, with two vertical bars provided. Both vertical bars are slidably connected to the base, and both vertical bars are fixedly connected to the horizontal bars. The horizontal bars are slidably connected to the slide plate.

[0015] In the above implementation process, the vertical and horizontal bars form a gate-shaped structure, which can help the slide plate slide horizontally on the base surface and keep its direction unchanged, so as to facilitate the observation of samples at different positions on the slide plate.

[0016] In one specific implementation, the guide frame further includes a limiting plate and a limiting block, the limiting block being fixedly connected to the slide plate, the limiting block abutting against the longitudinal rod, the limiting plate being fixedly connected to the longitudinal rod, and the limiting block abutting against the base.

[0017] In the above implementation process, the lateral adjustment range of the skateboard can be limited by the limiting block, and the longitudinal adjustment range of the skateboard can be limited by the limiting plate.

[0018] In one specific implementation, the adsorption mechanism includes a suction cup and a pull rod. The base has a groove adapted to the suction cup. The edge of the suction cup is fixedly connected to the base. The suction cup is in contact with the lower surface of the slide plate. The pull rod is fixedly connected to the center of the suction cup and moves through the base.

[0019] In the above process, pulling the suction cup can generate suction on the skateboard, thereby locking the skateboard so as to facilitate observation of the current sample.

[0020] In one specific implementation, the adsorption mechanism further includes a pad and an eccentric rod. The pad is fixedly connected to the base, the pull rod extends through the pad, the eccentric end of the eccentric rod is hinged to the pull rod, and the eccentric end of the eccentric rod abuts against the pad.

[0021] In the above implementation process, the pull rod is pulled and locked by rotating the eccentric rod, making the operation of locking the slide plate simpler.

[0022] Compared with the prior art, the beneficial effects of this application are: the freedom of the slide plate is used to quickly switch the sample under the microscope, the position of the slide plate is locked by the adsorption mechanism, the directionality of the slide plate is maintained by the guide frame, which facilitates accurate switching, and after the switching is completed, fine adjustment is performed by the fine adjustment mechanism, thus taking into account both rapid switching and precise fine adjustment.

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0030] Please see Figures 1-4This application provides a microscope support, including a base 10, a fine-tuning mechanism 20 at the rear end of the base 10, a mounting bracket 30 on the fine-tuning mechanism 20, a slide plate 40 slidably connected to the front end of the base 10, an adsorption mechanism 50 on the base 10 adsorbingly connected to the slide plate 40, and a guide frame 60 between the slide plate 40 and the base 10. The slide plate 40's freedom of movement allows for rapid sample switching under the microscope, the adsorption mechanism 50 locks the slide plate 40 in position, and the guide frame 60 maintains the slide plate 40's orientation for accurate switching. After switching, the fine-tuning mechanism 20 performs fine adjustments, thus balancing rapid switching with precise fine-tuning.

[0031] Please see Figures 1-4 The fine-tuning mechanism 20 includes a slide 21, which is slidably connected to the base 10. A slider 22 is slidably connected to the slide 21. The sliding directions of the slider 22 and the slide 21 are perpendicular to each other, thereby enabling free horizontal movement.

[0032] Please see Figures 1-4 Both the base 10 and the slide 21 are rotatably connected to lead screws 23. The two lead screws 23 are screwed to the slide 21 and the slider 22 respectively. Each lead screw 23 is fixedly connected to a handle 24. Rotating the handle 24 controls the rotation of the two lead screws 23 respectively, thereby driving the slide 21 and the slider 22 to make fine adjustments in the horizontal direction.

[0033] Please see Figures 1-4 The mounting bracket 30 includes a lifting bracket 31 and a mounting ring 32. The lower end of the lifting bracket 31 is fixedly connected to the slider 22, and the upper end of the lifting bracket 31 is fixedly connected to the mounting ring 32. A locking screw 33 is provided on the mounting ring 32. The lifting bracket 31 adopts a conventional screw lifting mechanism, which will not be described in detail here, to achieve fine adjustment in the vertical direction.

[0034] Please see Figures 1-4 The guide frame 60 includes two vertical bars 61 and two horizontal bars 62. Both vertical bars 61 are slidably connected to the base 10, and both vertical bars 61 are fixedly connected to the horizontal bars 62. The horizontal bars 62 are slidably connected to the slide plate 40. The vertical bars 61 and the horizontal bars 62 form a gate-shaped structure, which helps the slide plate 40 slide horizontally on the surface of the base 10 while maintaining a fixed direction, facilitating the observation of samples at different positions on the slide plate 40.

[0035] Please see Figures 1-4 The guide frame 60 also includes a limiting plate 63 and a limiting block 64. The limiting block 64 is fixedly connected to the slide plate 40 and abuts against the longitudinal rod 61. The limiting plate 63 is fixedly connected to the longitudinal rod 61, and the limiting block 64 abuts against the base 10. The limiting block 64 can limit the lateral adjustment range of the slide plate 40, and the limiting plate 63 can limit the longitudinal adjustment range of the slide plate 40.

[0036] Please see Figures 1-4 The adsorption mechanism 50 includes a suction cup 51 and a pull rod 52. A groove adapted to the suction cup 51 is provided on the base 10. The edge of the suction cup 51 is fixedly connected to the base 10. The suction cup 51 is in contact with the lower surface of the slide plate 40. The pull rod 52 is fixedly connected to the center of the suction cup 51 and extends through the base 10. Pulling the suction cup 51 generates suction on the slide plate 40, thereby locking the slide plate 40 for easy observation of the current sample.

[0037] Please see Figures 1-4 The adsorption mechanism 50 also includes a pad 53 and an eccentric rod 54. The pad 53 is fixedly connected to the base 10, and the pull rod 52 moves through the pad 53. The eccentric end of the eccentric rod 54 is hinged to the pull rod 52 and abuts against the pad 53. The pull rod 52 is pulled and locked by rotating the eccentric rod 54, making the operation of locking the slide plate 40 simpler.

[0038] The working principle of this microscope support is as follows: multiple samples are placed on the slide plate 40, and the slide plate 40 is supported to move horizontally, thereby moving the designated sample under the microscope. The eccentric rod 54 is rotated, and the eccentric rod 54, supported by the pad plate 53, pulls the pull rod 52, thereby causing the suction cup 51 to generate suction on the slide plate 40, thus locking the slide plate 40 in the current position. Then, the microscope is observed, and the two screws 23 are rotated by the two handles 24 respectively, thereby driving the slide base 21 and the slider 22 to make fine adjustments in the horizontal direction, so that the microscope can be aligned with the area to be observed. In summary, the freedom of the slide plate 40 is used to quickly switch the sample under the microscope, the suction mechanism 50 locks the position of the slide plate 40, and the guide frame 60 maintains the orientation of the slide plate 40 for accurate switching. After switching, fine adjustment is performed by the fine adjustment mechanism 20, thus taking into account both rapid switching and precise fine adjustment.
