The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, fig. 1 is a schematic view of an internal structure of a lens according to an embodiment of the present invention, and fig. 2 is a schematic view of a lens housing according to an embodiment of the present invention.

In a specific embodiment provided by the present invention, the microscopic observation angle adjusting mechanism mainly includes a lens body 1, a fixed abutting surface 2, an eyepiece 3, an objective 4 and a movable abutting post 5.

Wherein, the microscope body 1 is the major structure of the microscope, and simultaneously, the microscope body is also used as the installation place of the microscope observation angle adjusting mechanism, so that the microscope can be conveniently held by an operator to move or movably erected through structures such as an installation frame. In this embodiment, the overall structure of the mirror body 1 can be a rectangular box shape, which is convenient for the operator to grasp and pull, so that the operator can conveniently adjust the observation angle for many times. Meanwhile, in consideration of the requirements of scientific research images, the clamping piece 12 is additionally arranged at the bottom of the microscope body 1, and shooting equipment such as a mobile phone can be clamped through the clamping action of the clamping piece 12, so that a shooting port of the shooting equipment is aligned to the eyepiece 3 in the microscope body 1, and a microscopic workpiece image after microscopic amplification is shot in real time.

The fixed abutting surface 2 is arranged at the bottom of the mirror body 1, is positioned at one side of the bottom, is mainly used for abutting against the surface of the objective table, and can vertically and stably mount the mirror body 1 on the surface of the objective table. Eyepiece 3 and objective 4 all set up in the mirror body 1, and for guaranteeing the normal stack of magnification, eyepiece 3 can be located mirror body 1 top, the people's eye of being convenient for observes, and objective 4 can be located mirror body 1 bottom to just to setting up with eyepiece 3, vertical distribution is all followed to both, can follow vertical observation microscopic workpiece.

What is important is that, in addition to the fixed abutment surface 2, a movable abutment 5 is provided at the other side of the bottom of the mirror body 1, and the movable abutment 5 is mainly used for abutment with the surface of the stage, as with the fixed abutment surface 2, but the difference is that the movable abutment 5 can slide vertically in the mirror body 1. Generally, when the microscope slide to the bottom of the microscope 1, the bottom surface of the movable abutment post 5 and the bottom surface of the fixed abutment surface 2 form the bottom surface of the microscope 1, and the two are pressed against the surface of the stage, so that the operator can vertically observe the microscope to obtain the top view.

When the microscope work piece is observed in a multi-angle space, the movable abutting column 5 can be operated firstly to enable the movable abutting column 5 to rise to a certain height in the microscope body 1, so that the bottom surface of the movable abutting column 5 and the bottom surface of the fixed abutting surface 2 form a step surface with a certain height difference, at the moment, an operator can manually pull the microscope body 1 or pull the microscope body 1 by means of structures such as an installation frame and the like to enable the microscope body to turn over for a certain angle in the space, and the bottom surface edge of the movable abutting column 5 and the bottom surface edge of the fixed abutting surface 2 are enabled to stably abut against the surface of the objective table simultaneously. Because the lens body 1 is turned over for a certain angle in space, the ocular lens 3 and the objective lens 4 are not perpendicular to the surface of the microscopic workpiece any more, and at the moment, an operator can conveniently observe the microscopic workpiece for a space angle to obtain an axial view angle field. Meanwhile, different sliding heights of the movable abutting column 5 in the mirror body 1 and the fixed abutting surface 2 form step surfaces with different height differences, and then different space angle viewing angles can be formed.

In conclusion, the observation angle adjusting mechanism provided by the embodiment can conveniently and rapidly realize the space multi-angle microscopic observation of the microscopic workpiece, and improve the microscopic observation operation efficiency.

In one embodiment, the movable abutment 5 is collinear with the central axis of the objective lens 4 and the eyepiece 3, which are connected to form a line on the lens body 1, and the movable abutment 5 is disposed on one side of the bottom of the lens body 1 (left side of the figure) and at the bottom of the lens barrel of the objective lens 4, while the fixed abutment 2 is disposed on the other side of the bottom of the lens body 1 (right side of the figure). At this time, in order to ensure that the light can smoothly pass through the ocular lens 3 and the objective lens 4 and then reach the carrier sheet on the surface of the stage, the inside of the movable abutment post 5 needs to be hollowed into a through hole, so that the overall structure of the movable abutment post 5 is closer to a cylindrical shape. Of course, the movable abutment 5 may also be offset from the objective 4 and the eyepiece 3.

To facilitate the vertical sliding movement of the movable abutment post 5 in the mirror body 1, the present embodiment provides a slide rail 101 on the inner wall surface of the mirror body 1, and at the same time slidably arranges the inner side wall of the movable abutment post 5 in the slide rail 101. Specifically, the slide rail 101 extends in the vertical direction on the mirror body 1, and the movable abutment post 5 can be embedded in the slide rail 101 for sliding through a structure such as a slide block on the inner side wall.

Meanwhile, considering that the movable abutment post 5 is disposed inside the mirror body 1, in order to facilitate the operator to operate the movable abutment post 5, the adjusting rod 501 is additionally disposed on the outer side wall of the movable abutment post 5, and correspondingly, the adjusting hole 102 is further disposed on the surface of the mirror body 1. Specifically, the outer end of the adjusting rod 501 can protrude out of the side wall of the mirror body 1 through the adjusting hole 102, and the adjusting hole 102 can be an oblong hole and is distributed along the vertical direction. Thus, an operator can toggle the adjusting rod 501 by a finger, so that the adjusting rod 501 slides in the adjusting hole 102, and the movable abutting rod slides in the sliding rail 101.

Furthermore, considering that most of the bottom surfaces of the fixed abutment surface 2 and the movable abutment post 5 will not form surface-to-surface contact with the surface of the stage any more when adjusting the observation angle of the microscope, but the small area range of the edge or edge area of the fixed abutment surface 2 and the movable abutment post will form similar line-to-surface contact with the surface of the stage, the latter has strong stress concentration phenomenon, and in order to reduce the abrasion between the fixed abutment surface and the stage surface, a layer of abutment plate 502 is connected to the bottom of the movable abutment post 5 in the present embodiment, and the material of the abutment plate 502 is an elastic soft material, which can buffer the vibration, reduce the impact, and reduce the pressure, such as a rubber plate, a polyurethane plate, and the like. The fixed abutting surface 2 may be formed by using an elastic soft material as a material of a bottom surface thereof.

Furthermore, in the present embodiment, a support roller 503 is additionally provided on one side of the abutment plate 502 to improve the mounting stability of the scope 1 on the stage after the adjustment of the observation angle. Specifically, the bottom surface of the supporting roller 503 is generally circular arc-shaped, and has a larger surface area than a plane surface, and is easier to contact and press with the surface of the stage. When the angle of the mirror body 1 is reversed, the supporting roller 503 can be pressed on the bottom surface of the objective table instead of the bottom surface edge of the movable abutting column 5.

In addition, when the operator performs the observation operation, the height of the eyepiece 3 and the objective lens 4 may need to be adjusted at any time so as to adjust the magnification, and for this reason, the first rack-and-pinion mechanism 6 and the second rack-and-pinion mechanism 7 are provided in the scope body 1 in the present embodiment. Wherein, the first gear rack transmission mechanism 6 is mainly used for adjusting the vertical height of the ocular lens 3, and the second gear rack transmission mechanism 7 is mainly used for adjusting the vertical height of the objective lens 4. The transmission state of the first gear rack transmission mechanism 6 is mainly controlled by an ocular lens adjusting wheel 8 arranged on the surface of the lens body 1, and the transmission state of the second gear rack transmission mechanism 7 is controlled by an objective lens adjusting wheel 9 also arranged on the surface of the lens body 1.

Specifically, the eyepiece regulating wheel 8 and the objective regulating wheel 9 are rotatably embedded on the surface of the lens body 1, so that an operator can stir fingers to rotate. In the mirror body 1, the pivot of eyepiece regulating wheel 8 links to each other with the gear among the first rack and pinion drive mechanism 6, and its rack is again along vertical arranging on eyepiece 3 simultaneously, so, when eyepiece regulating wheel 8 was rotatory, the gear synchronous revolution that corresponds, and the gear again with rack toothing transmission for the rack drives eyepiece 3 along vertical motion, so realized the high position control of eyepiece 3. Similarly, the height position adjustment principle for the objective 4 and the control method for the objective adjustment wheel 9 to the second gear rack transmission mechanism 7 are the same, and are not described herein again. The difference is that the adjustment accuracy of the eyepiece adjustment wheel 8 and the adjustment accuracy of the objective adjustment wheel 9 are different, and generally speaking, the adjustment accuracy of the eyepiece adjustment wheel 8 is thick, and the adjustment accuracy of the objective adjustment wheel 9 is thin.

In addition, in order to avoid image blurring caused by careless misoperation of the eyepiece adjusting wheel 8 or the objective adjusting wheel 9 when the operator adjusts the magnification and performs observation, the surface of the lens body 1 is further provided with a transverse control groove 103. Specifically, the eyepiece regulating wheel 8 is arranged in the transverse control groove 103 and can slide back and forth along the transverse direction (axial direction) at a certain distance under the stirring of an operator, when the eyepiece regulating wheel slides to the right side wall tightly attached to the transverse control groove 103 along the transverse right side of the figure, the eyepiece regulating wheel 8 drives the gear to move towards the right side, so that the gear and the rack are disengaged, the transmission of the gear and the rack is failed at the moment, and the height position of the eyepiece 3 cannot be influenced no matter how the eyepiece regulating wheel 8 rotates; on the contrary, when the eyepiece regulating wheel 8 slides to the left side wall tightly attached to the transverse control groove 103, the eyepiece regulating wheel 8 drives the gear to move towards the left side, so that the gear and the rack are kept in a meshing state again, the gear and the rack are in normal transmission, and the eyepiece regulating wheel 8 can normally regulate the height position of the eyepiece 3. Thus, after the magnification is adjusted, the operator can lock the height position and magnification of the eyepiece 3 by toggling the eyepiece adjustment wheel 8 in the lateral control slot 103. Similarly, the height position and the magnification of the objective lens 4 can be locked by the same structure.

In another embodiment, in order to conveniently realize multi-color environment imaging of the microscopic workpiece, in this embodiment, a plurality of LED lamps 10 are disposed at the bottom of the mirror body 1, and a cold-warm color plate 11 is disposed at a bottom through hole of the mirror body 1. Specifically, each LED lamp 10 may emit white light or light with a specific color, and the cold/warm color plate 11 may slide on the bottom of the mirror body 1, mainly serving to filter the light emitted by the LED lamp 10, so as to form cold color dimming or warm color dimming, and controlling whether to filter the light of the LED lamp 10 by sliding at a position of the bottom through hole of the mirror body 1.

The present embodiment further provides a microscope, which mainly includes a microscope body 1 and a microscopic observation angle adjusting mechanism disposed in the microscope body 1, wherein the main content of the microscopic observation angle adjusting mechanism is the same as the related content, and is not described herein again.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
