DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-6 This application is described in further detail.
[0033] Embodiment 1: The present application embodiment discloses a cooperative multi-person co-viewing microscope, such as Figure 1 , 2 As shown in Figure 3, it includes a main microscope 1, a plurality of observation eyepieces 12 and a coordination mechanism 3. Each observation eyepiece 12 is arranged in a row, and the main microscope 1 is located in the middle. A connecting tube 13 is connected between the observation eyepiece 12 close to the main microscope 1 and the main microscope 1, and between two adjacent observation eyepieces 12. The connecting tube 13 can transmit the image information collected by the eyepiece of the main microscope 1 to each observation eyepiece 12 in an optical or digital manner. The main microscope 1 is provided with a cursor board 14 and a control component 2. The cursor board 14 is located under the objective lens of the main microscope 1, above the sample, and moves relative to the main microscope 1. The cursor board 14 is provided with a cursor point 141. When using the microscope for teaching, the operator of the main microscope 1 can control the movement of the cursor board 14 through the control component 2, and use the cursor point 141 in the field of view to indicate the image information. The coordination mechanism 3 is used to enable the trainees located at the observation eyepiece 12 to operate the control component 2.
[0034] like Figure 2 and 3 As shown, the surface of the cursor board 14 is parallel to the surface of the glass slide containing the sample and perpendicular to the length direction of the objective lens; the material of the cursor board 14 is transparent glass, and the cursor points 141 are color spots fixedly coated on the surface of the cursor board 14. In this embodiment, there are three cursor points 141 on the cursor board 14, and the colors of the three cursor points 141 are respectively the three primary colors of vision: red, green and blue. When the operator moves the cursor board 14, the cursor point 141 with a larger color difference from the sample color should be used for indication to ensure the clarity of the indication effect of the cursor point 141.
[0035] like Figure 2 and 3 As shown, the control assembly 2 includes a first operating rod 21 and a second operating rod 22, both of which are rotatably connected to the main microscope 1, the axes of the first operating rod 21 and the second operating rod 22 are vertical and horizontal, and the length direction of the second operating rod 22 is parallel to the arrangement direction of each observation eyepiece 12. The surface profile of the cursor board 14 is square, and two adjacent edges of the cursor board 14 are slidably connected with control rails 23, and the sliding direction is parallel to the edge of the cursor board 14 where the control rails 23 are located. A control screw barrel 24 is fixedly connected to the control rail 23, and the control screw barrel 24 is slidably connected to the main microscope 1, and the sliding direction is the direction of its own length. The first operating rod 21 is threadedly connected to the control screw barrel 24 on one of the control rails 23, and the second operating rod 22 is threadedly connected to the control screw barrel 24 on the other control rail 23; when the first operating rod 21 rotates, the control screw barrel 24 threadedly connected thereto moves along its own length direction, and the second operating rod 22 is the same. Therefore, the operator can control the lateral two-dimensional movement of the cursor board 14 through the first operating rod 21 and the second operating rod 22.
[0036] like Figure 1 and 4 As shown, the coordination mechanism 3 includes a base frame 31 and a connection assembly 33. The main microscope 1 and each observation eyepiece 12 are located on the base frame 31. An operator 32 is provided on the base frame 31 and at each observation eyepiece 12. The connection assembly 33 is used to selectively establish a torque transmission relationship between the operator 32 and the control assembly 2. The connection assembly 33 includes a torque transmitter 331 and a linkage rod 332. There are two linkage rods 332 and two torque transmitters 331. The linkage rods 332 are rotatably connected to the base frame 31. The length directions of the two linkage rods 332 are parallel to the length direction of the second operating rod 22. The operator 32 is an operating wheel. There are two operating wheels at each observation eyepiece 12. A single operating wheel is coaxially fixedly connected to a linkage rod 332. The trainee can control the rotation of the linkage rod 332 by rotating the operating wheel. The torque transmitter 331 and the linkage rod 332 correspond to each other one by one. A single linkage rod 332 transmits torque to the first operating rod 21 or the second operating rod 22 through a torque transmitter 331. The torque transmitter 331 is a gear reducer installed on the main microscope 1, and the torque transmitter 331 for transmitting torque to the first operating rod 21 is a reversing reducer. A gear is connected to the input end of the torque transmitter 331, and a linkage gear 3321 is coaxially connected to the linkage rod 332. The linkage gear 3321 is meshed with the gear at the input end of the torque transmitter 331, and the linkage gear 3321 on the linkage rod 332 for transmitting torque to the first operating rod 21 is a bevel gear.
[0037] like Figure 1 and 4As shown, the two torque output devices share a housing, and the connection assembly 33 further includes an output gear 3313, a mechanism gear 333 and an operating gear 334. The output gear 3313 is coaxially connected to the output shaft of the torque transmitter 331. A mechanism frame 335 is rotatably provided on the housing of the torque transmitter 331, and the rotation axis of the mechanism frame 335 coincides with the rotation axis of the output gear 3313. The mechanism gear 333 is rotatably provided on the mechanism frame 335. No matter to which angle the mechanism frame 335 rotates, the mechanism gear 333 is always meshed with the output gear 3313. There are two operating gears 334, one of which is coaxially fixedly connected to the first operating rod 21, and the other is coaxially fixedly connected to the second operating rod 22. During the rotation of the mechanism frame 335, the mechanism gear 333 can move closer to or away from the operating gear 334, so that the laser gear can abut against the operating gear 334 and the two can mesh. At this time, the torque output by the torque transmitter 331 can finally be transmitted to the first operating rod 21 or the second operating rod 22.
[0038] like Figure 4 and 5 As shown, the rotation axes of the two mechanism frames 335 are both horizontal and perpendicular to each other. The connection assembly 33 also includes an adjustment member for controlling the rotation of the mechanism frames 335. In this embodiment, the adjustment member is a pull rod 337. The pull rod 337 is slidably connected to the housing of the torque transmitter 331, and the sliding direction is vertical and perpendicular to the rotation axis of the mechanism frames 335. The side wall of the pull rod 337 is provided with two thrust wedges 338. The wedge surfaces of the two thrust wedges 338 respectively abut against the sides of the two mechanism frames 335 away from the operating gear 334. A return spring 336 is provided on the housing of the gear reducer. The end of the return spring 336 is connected to the mechanism frame 335. The return spring 336 always applies a thrust to the mechanism frame 335 to make it away from the operating gear 334. In a natural state, the mechanism frame 335 is located at an angle position where the mechanism gear 333 and the operating gear 334 are not meshed. When the pull rod 337 moves upward, the wedge surface of the thrust wedge block 338 generates thrust on the mechanism frame 335, and the mechanism frame 335 swings and finally causes the mechanism gear 333 and the operating gear 334 to abut and mesh.
[0039] like Figure 4 and 5As shown, the upper end of the pull rod 337 is coaxially connected to the anti-recoil cylinder 339, and the anti-recoil cylinder 339 passes through the housing of the torque transmitter 331. The housing of the gear reducer is provided with a clearance hole 3311 for the anti-recoil cylinder 339 to pass through. The outer wall of the anti-recoil cylinder 339 is in contact with the hole wall of the clearance hole 3311. The operator of the main microscope 1 can drive the pull rod 337 to move upward by pulling up the anti-recoil cylinder 339. A stop block 3391 is fixedly connected to the side wall of the stop cylinder 339, and a block groove 3312 is provided on the wall of the giving hole 3311 for the stop block 3391 to pass through; when the stop cylinder 339 moves upward to cause the mechanism gear 333 and the operating gear 334 to engage, the stop block 3391 is just located outside the housing of the gear reducer. At this time, the stop cylinder 339 is rotated to make the stop block 3391 leave the block groove 3312 and abut the outer wall of the housing of the gear reducer. The positions of the stop cylinder 339 and the pull rod 337 are fixed, and at the same time, the torque output by the gear reducer can also be stably transmitted to the first operating rod 21 or the second operating rod 22.
[0040] Embodiment 2: like Figure 6 As shown, the difference from the above embodiment is that the operating wheel and the linkage rod 332 are not fixedly connected in this embodiment. A clutch ring 311 is slidably provided on the base frame 31, and the sliding direction is parallel to the axial direction of the linkage rod 332, and the clutch ring 311 is coaxially sleeved outside the linkage rod 332; the operating wheel is coaxially connected to one end of the clutch ring 311, and the linkage shaft passes through the clutch ring 311 and the operating wheel, but does not contact the clutch ring 311 and the operating wheel. A clutch shoulder 3322 is coaxially fixedly connected to the side wall of the linkage rod 332, and the clutch shoulder 3322 is located on the side of the operating wheel away from the clutch ring 311. The clutch shoulder 3322 and the operating wheel are coaxially fixedly connected with a cooperative sawtooth ring 5, and the cooperative sawtooth ring 5 on the clutch shoulder 3322 is opposite to the cooperative sawtooth ring 5 on the operating wheel.
[0041] like Figure 6 As shown, the clutch ring 311 can be driven electrically or pneumatically. In the initial state, the cooperative serrated ring 5 of each operating wheel does not contact the cooperative serrated ring 5 on the clutch shoulder 3322, that is, the linkage rod 332 cannot be controlled by the operating wheel. The operator of the main microscope 1 can selectively control one of the clutch rings 311 to move its corresponding operating wheel against the clutch shoulder 3322, the cooperative serrated ring 5 on the operating wheel and the clutch serrated ring on the clutch shoulder 3322 are meshed with each other, the operating wheel and the cooperative serrated ring 5 are relatively fixed in the circumferential direction, and the corresponding observation eyepiece 12 operator can control the rotation of the linkage rod 332 through the operating wheel, thereby controlling the control assembly 2.
[0042] The implementation principle of a collaborative multi-person co-viewing microscope in the present application embodiment is as follows: During the teaching process, the operator of the main microscope 1 uses the cursor point 141 to explain the image in the field of view, and the students observing the eyepiece 12 obtain the image collected by the main microscope 1 by observing the eyepiece 12. At this time, the pull rod 337 is located at a lower position, and torque cannot be transmitted between each operating wheel and the first operating rod 21 or the second operating rod 22. When the student needs to operate the control component 2, the operator of the main microscope 1 pulls the pull rod 337 to enable the connection component 33, and each student can control the movement of the cursor board 14 through the operating wheel.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
