Description

Technical Field

[0001] The present invention relates to the technical field of multi - view microscopes, and particularly to a multi - view microscope for laboratory use that is convenient for multi - angle adjustment. Background Art

[0002] A multi - view microscope is a precision instrument used in laboratories for multi - perspective synchronous observation or recording of samples. Its core function is to achieve synchronous analysis of samples under different angles, different optical modes, or different imaging techniques through the combination of multiple optical channels (such as eyepieces, cameras, etc.). In materials science and biology, it is often necessary to combine an optical microscope with an electron microscope probe, a spectrometer, etc. to simultaneously obtain morphology, composition, and spectral data. Traditional devices need to frequently replace modules, with low efficiency and easy damage to sample positioning. To reconstruct a three - dimensional model of a sample through multi - angle imaging data (such as oblique observation), precise control of the angle parameters of each lens is required.

[0003] When adjusting the angle, manually adjusting the lens angle depends on screws or turntables, which is prone to affecting the imaging stability due to mechanical vibration. Traditional devices are prone to damaging sample positioning when frequently replacing modules. Summary of the Invention

[0013] The present invention provides a multi-purpose instrument for laboratory use that is convenient for multi-angle adjustment. It has the following beneficial effects: 1. For the multi-purpose instrument for laboratory use that is convenient for multi-angle adjustment, an adjustment frame is provided to drive the first rack to move. The movement of the first rack drives the first gear to rotate. The rotation of the first gear drives the observation device to rotate, so as to drive different lenses to be at different angles. When the driving component is inside different adjustment frames, the corresponding component of the driving component cooperates with the sliding shaft at the bottom of the adjustment frame to drive the adjustment frame to slide along the side surface, so as to drive the first gear to rotate. When the adjustment frame moves, the adjustment frame drives the second rack to move along the corresponding rack at the bottom of the fixed housing, so that the second rack and the fixed housing cooperate to brake when the adjustment frame moves to the appropriate position, so that the position of the adjustment frame and the fixed housing is fixed at a fixed position, so as to fix the angle adjustment of the observation device, which is beneficial to the cooperative work between multiple groups of lenses.

[0014] 2. The multi-purpose instrument for laboratory use that is convenient for multi-angle adjustment is provided with a second rack for movement. The movement of the second rack brakes with the rack at the bottom of the fixed housing, and drives the first top plate to contact the brake plate through the elastic force of the first spring. The side of the brake plate is fixedly connected to the first top plate. The fixed position of the first top plate provides a downward force to drive the first spring to compress, so that the adjustment frame makes the second rack at the bottom of the adjustment frame brake with the inner wall bottom of the fixed housing under the elastic force of the first spring, so that the second rack meshes with the rack at the inner wall bottom of the fixed housing under the elastic force of the first spring, so as to maintain a static state and prevent the lens from shifting. At the same time, the setting of the first spring reduces the influence of vibration on the adjustment frame, absorbs the vibration through the elasticity of the first spring, and prevents the vibration generated when the second rack meshes with the fixed housing from being transmitted to the lens.

[0015] 3. The multi-purpose instrument for laboratory use that is convenient for multi-angle adjustment is provided with a rotating handle. The rotating handle drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the brake top bar to rotate. The side of the brake top bar contacts the inner wall of the adjustment frame, so that the brake top bar pushes the adjustment frame to move upward. The upward movement of the adjustment frame drives the second rack to disengage from the inner wall bottom of the fixed housing. Driving the reverse rotation drives the adjustment frame to move, so as to perform the angle rotation adjustment. The second slip ring and the first slip ring are used to determine the position of the rotation center of the first rotating shaft, and the first slip ring and the second slip ring slide in the corresponding sliding grooves of the adjustment frame and the moving bracket, drive the first rotating shaft to slide when adjusting different lenses, so as to drive different lenses to adjust the angle. When the first rotating shaft moves to another position, the adjustment frame maintains the braking position, so as to prevent other lenses from moving when adjusting the lens.

[0016] 4. The multi-purpose instrument for laboratory use that is convenient for multi-angle adjustment is provided with a first motor. The drive shaft of the first motor drives the screw to rotate. The rotation of the first motor drives the sliding shaft at the bottom of the adjustment frame to move, so as to drive the adjustment frame to move. The slider and the second spring cooperate to press down the moving bracket, so as to keep the drive shaft of the first motor stuck in the sliding groove at the top of the brake top bar, so that the top of the screw meshes well with the bottom of the adjustment frame, so as to perform the drive. The pulling handle is used to drive the moving bracket to slide, so as to drive different adjustment frames, so as to adjust different lenses.

[0017] 5. The multi-purpose instrument for laboratory use that is convenient for multi-angle adjustment is provided with a starting electric screw. The rotation of the electric screw drives the adjustment bottom plate to move up and down. The movement of the adjustment bottom plate drives the movement of the third rack. The movement of the third rack drives the movement of the rotating bottom plate. The movement of the rotating bottom plate drives the movement of the rotating seat. Manually rotate the connecting plate, and the connecting plate rotates on the side of the rotating seat. The connecting plate drives the rotating sleeve to rotate. The rotation of the rotating sleeve is braked with the braking rotating plate through the internal rack. The braking rotating plate rotates along the side of the rotating shaft under the elastic force of the fourth spring, thereby driving the braking rotating plate to engage with the rotating sleeve for braking, so that the rotating sleeve rotates along the rotating seat, and thus the connecting plate rotates unidirectionally on the side of the rotating seat. When rotating in the reverse direction, the inner wall of the rotating sleeve brakes with the braking rotating plate, thereby avoiding the observation error caused by spontaneous rotation after being adjusted to the appropriate position.

Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1 - Figure 2 , the present invention provides a technical solution: a multi-purpose instrument for a laboratory that is convenient for multi-angle adjustment, including a bottom plate bracket 1, a bottom plate 2 is fixedly connected to the top of the bottom plate bracket 1, an adjustment device 3 is fixedly connected to the top of the bottom plate 2, and an observation device 4 is fixedly connected to the top of the adjustment device 3.

[0022] The bottom plate bracket 1 and the bottom plate 2 support the equipment as a whole. The adjustment device 3 adjusts the observation device 4 at different angles and maintains a fixed angle after adjusting to the specified angle. Through the drive of the motor, the adjustment of the multi-purpose lens is realized, so as to observe the observed object at different angles. And through the corresponding components of the observation device 4, the lens is adjusted separately, and adjusted at different angles and different distances according to actual needs, so as to observe the observed object at different angles and distances.

[0023] The adjustment device 3 includes a fixed housing 301. The top of the fixed housing 301 is rotatably connected to a first gear 302 through a rotating shaft. A first rack 303 is engaged with the bottom of the first gear 302. The bottom of the first rack 303 is fixedly connected to an adjustment frame 304. An elastic component 305 is fixedly connected to the top of the adjustment frame 304 at a position below the first rack 303. The bottom of the adjustment frame 304 is fixedly connected to a second rack 306. A rack adapted to the second rack 306 is fixedly connected to the bottom inner wall of the fixed housing 301. A moving bracket 307 is fixedly connected to the side of the fixed housing 301. A fixing component 308 penetrates and is slidably connected to the side of the moving bracket 307. A driving component 309 is fixedly connected to the side of the moving bracket 307 at a position above the fixing component 308. A sliding shaft adapted to the driving component 309 is fixedly connected to the top inner wall of the adjustment frame 304. The side of the first gear 302 is fixedly connected to the inner wall of the observation device 4. The bottom of the fixed housing 301 is fixedly connected to the top of the bottom plate 2.

[0024] Start the driving component 309. The driving component 309 drives the adjustment frame 304 through the corresponding components, so that the adjustment frame 304 drives the first rack 303 to move. The movement of the first rack 303 drives the first gear 302 to rotate. The rotation of the first gear 302 drives the observation device 4 to rotate, so as to drive different lenses at different angles. When the driving component 309 is inside different adjustment frames 304, the corresponding components of the driving component 309 cooperate with the sliding shaft at the bottom of the adjustment frame 304 to drive the adjustment frame 304 to slide along the side of 201, so as to drive the first gear 302 to rotate. When the adjustment frame 304 moves, the adjustment frame 304 drives the second rack 306 to move along the corresponding rack at the bottom of the fixed housing 301, so that the second rack 306 and the fixed housing 301 cooperate to brake when the adjustment frame 304 moves to a suitable position, so that the position of the adjustment frame 304 and the fixed housing 301 is fixed at a fixed position, so as to fix the angle adjustment of the observation device 4, which is beneficial to the cooperation work between multiple groups of lenses.

[0025] Please refer to Figure 1 - Figure 4 As shown in the figure, the present invention provides a technical solution: The elastic component 305 includes a first top plate 3051. A first spring 3052 is fixedly connected to the bottom of the first top plate 3051. One end of the first spring 3052 away from the first top plate 3051 is fixedly connected to a fixed column 3053. The elastic component 305 further includes a brake plate 3054. The bottom of the fixed column 3053 is fixedly connected to the bottom inner wall of the elastic component 305. The side of the brake plate 3054 is fixedly connected to the side inner wall of the fixed housing 301.

[0026] When the adjustment frame 304 moves, the movement of the adjustment frame 304 drives the second rack 306 to move. The movement of the second rack 306 brakes with the rack at the bottom of the fixed housing 301, and drives the first top plate 3051 to contact the brake plate 3054 through the elastic force of the first spring 3052. The brake plate 3054 is fixedly connected to the side of the first top plate 3051. The fixed position of the first top plate 3051 provides a downward force to drive the first spring 3052 to compress. Thus, under the elastic force of the first spring 3052, the second rack 306 at the bottom of the adjustment frame 304 brakes with the inner wall bottom of the fixed housing 301, so that the adjustment frame 304 makes the second rack 306 engage with the rack at the inner wall bottom of the fixed housing 301 under the elastic force of the first spring 3052, thereby maintaining a static state and preventing the lens from shifting. At the same time, the setting of the first spring 3052 reduces the influence of vibration on the adjustment frame 304, absorbs the vibration through the elasticity of the first spring 3052, and prevents the vibration generated when the second rack 306 engages with the fixed housing 301 from being transmitted to the lens.

[0027] The fixing assembly 308 includes a first rotating shaft 3081. A braking top bar 3082 is fixedly connected to the side of the first rotating shaft 3081. A first slip ring 3083 is fixedly connected to one end of the first rotating shaft 3081. A second slip ring 3084 is fixedly connected to the end of the first rotating shaft 3081 away from the first slip ring 3083. A rotating handle 3085 is fixedly connected to the part of the first rotating shaft 3081 on the side of the second slip ring 3084. A chute adapted to the first slip ring 3083 is provided in the inner wall of the adjustment frame 304. A chute adapted to the second slip ring 3084 is provided on the side of the moving bracket 307. The braking top bar 3082 extends into the interior of the adjustment frame 304.

[0028] When angle rotation adjustment is required, manually twist the rotating handle 3085. The rotation of the rotating handle 3085 drives the first rotating shaft 3081 to rotate. The rotation of the first rotating shaft 3081 drives the braking top bar 3082 to rotate. The side of the braking top bar 3082 contacts the inner wall of the adjustment frame 304, so that the braking top bar 3082 pushes the adjustment frame 304 to move upward. The upward movement of the adjustment frame 304 drives the second rack 306 to disengage from the bottom inner wall of the fixed housing 301. The reverse rotation of the drive assembly 309 drives the adjustment frame 304 to move, thereby performing angle rotation adjustment. The second slip ring 3084 and the first slip ring 3083 are used to determine the position of the rotation center of the first rotating shaft 3081, and the first slip ring 3083 and the second slip ring 3084 slide in the corresponding sliding grooves of the adjustment frame 304 and the moving bracket 307. When adjusting different lenses, it drives the first rotating shaft 3081 to slide, thereby driving different lenses to adjust the angle. When the first rotating shaft 3081 moves to another position, the adjustment frame 304 maintains the braking position, thereby preventing other lenses from moving when adjusting the lens.

[0029] Please refer to Figure 1 - Figure 5 As shown in the figure, the present invention provides a technical solution: The drive assembly 309 includes a drive frame 3091.

A pulling handle 3098 is fixedly connected to the side of the movable frame 3093. The pulling handle 3098 penetrates the side of the drive frame 3091 and is slidably connected to the drive frame 3091.

[0030] Start the first motor 3094. The drive shaft of the first motor 3094 drives the screw 3095 to rotate. The rotation of the first motor 3094 drives the sliding shaft at the bottom of the adjustment frame 304 to move, thereby driving the adjustment frame 304 to move. The slider 3096 and the second spring 3097 cooperate to press down on the movable frame 3093, so as to keep the drive shaft of the first motor 3094 stuck in the sliding groove at the top of the braking top bar 3082, so that the top of the screw 3095 meshes well with the bottom of the adjustment frame 304, thereby performing driving.
