Description

Technical Field

[0001] The utility model relates to the technical field of optics, in particular to an eyepiece assembly and an optical mirror. Background Art

[0002] Optical mirrors, such as telescopes and microscopes, both include an objective lens and an eyepiece. The eyepiece is located on the side close to the human eye, while the objective lens is located on the side far from the human eye. The objective lens of a microscope is equivalent to a projector to form an inverted and magnified real image. The eyepiece of a microscope is equivalent to a magnifying glass, which magnifies the inverted and magnified real image formed by the projector again to form an inverted and magnified virtual image. The objective lens of a telescope is equivalent to a camera to form an inverted and reduced real image, and this real image exactly falls within the focal point of the eyepiece, which is the same as the imaging principle of a magnifying glass. The eyepiece of a telescope plays a role in magnifying the reduced real image formed by the objective lens again.

[0048] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0049] As Figures 1 to 5 shown, an embodiment of the present application provides an eyepiece assembly, including: a main housing 1, an optical element (not shown), and a rotating housing 2. The main housing 1 has a cavity, and the cavity includes an incident channel 11 and an exit channel 12. The incident channel 11 and the exit channel 12 are connected and communicated. The optical element is disposed in the cavity. The light incident into the incident channel 11 is incident on the optical element, and the light emitted by the optical element is emitted from the main housing 1 along the exit channel 12. The rotating housing 2 is rotatably sleeved on the main housing 1. A plurality of eyepiece mounting cylinders 21 are provided on the rotating housing 2, and the eyepiece mounting cylinders 21 are sequentially spaced along the circumferential direction of the rotating housing 2. An eyepiece (not shown) is mounted on the eyepiece mounting cylinder 21. Rotating the rotating housing 2 around the main housing 1 can make any one of the eyepiece mounting cylinders 21 communicate with the exit channel 12.

[0050] The degrees of each eyepiece are different (such as diopter), and by rotating the rotating shell 2 of the eyepiece assembly of the present application, different eyepieces can be adjusted to communicate with the exit channel 12 (that is, the eyepiece is located on the extension line of the exit channel 12), so that the magnification effect and clarity of the object in the observation area can be conveniently adjusted to meet the usage requirements of different observation scenarios of users. The eyepiece assembly of the present application can be applied to telescopes or microscopes. The eyepiece assembly can be an independent part, detachably mounted on the main body of the optical mirror, or fixedly connected to the main body of the optical mirror to form an integral structure.

[0051] The eyepiece mounting cylinder 21 can include a plurality of arc-shaped pieces, each arc-shaped piece is arranged at intervals in the circumferential direction in turn, there is a gap between adjacent arc-shaped pieces, and an external thread is arranged on the outer wall of the arc-shaped piece. The eyepiece (including the cylinder shell and the lens) can be at least partially inserted into the eyepiece mounting cylinder 21, and the locking sleeve 4 has an internal thread, and the locking sleeve 4 is threadedly connected to the eyepiece mounting cylinder 21 to press and fix the eyepiece.

[0052] In some possible implementation manners, the optical element is a reflecting mirror or a refracting mirror. The refracting mirror can be a prism. A prism is usually a transparent optical element with a triangular cross-section. The incident light undergoes two consecutive refractions, and both refractions deflect the light in the direction of the base of the prism, ultimately producing a significant net deflection angle.

[0053] In some possible implementation manners, as Figure 5 shown, a support plate 16 is arranged in the cavity. The support plate 16 extends from one side of the incident channel 11 to one side of the exit channel 12, and the optical element is fitted and mounted on the support plate 16. The support plate 16 is inclined in the cavity, which facilitates the support and installation of the optical element. For example, the incident channel 11 and the exit channel 12 are perpendicular to each other, the support plate 16 is located on the side where the incident channel 11 and the exit channel 12 intersect, and the support plate 16 forms an angle of 135° with the incident channel 11 and the exit channel 12 respectively.

[0054] In some possible implementation manners, the support plate 16 is provided with a card slot 161, and the optical element can be snapped into the card slot 161. The optical element can be stably assembled on the support plate 16.

[0055] Card slots 161 are provided on both opposite sides of the support plate 16, and both sides of the optical element can be clamped and fixed simultaneously.

[0056] In some possible implementation manners, the main shell 1 includes two half shells 13, and the two half shells 13 respectively have half support plates 16. In the state where the two half shells 13 are connected, the half support plates 16 of the two half shells 13 are spliced to form a complete support plate 16, and card slots 161 are provided on both sides of the two half shells. After the two half support plates 16 are spliced, the opposite card slots 161 are communicated with each other.

[0057] In some possible embodiments, in the main housing 1 and the rotating housing 2, a positioning portion 14 is provided on one of them, and a positioning and mating portion 22 is provided on the other. In a state where the rotating housing 2 rotates around the main housing 1 such that the positioning portion 14 and the positioning and mating portion 22 are snap-fitted, the exit channel 12 communicates with an eyepiece mounting cylinder 21.

[0058] In this embodiment, through the settings of the positioning portion 14 and the positioning and mating portion 22, the rotation angle of the rotating housing 2 can be limited, such that when the rotating housing 2 rotates to a position where the exit channel 12 communicates with any one of the eyepiece mounting cylinders 21, the positioning portion 14 and the positioning and mating portion 22 are positioned and mated to fix the relative positions of the main housing 1 and the rotating housing 2, preventing the rotating housing 2 from easily rotating and shifting.

[0059] In some possible embodiments, in combination Figure 3 and Figure 4 as shown, a positioning portion 14 is provided on the main housing 1, and a plurality of positioning and mating portions 22 are provided on the rotating housing 2. The positioning and mating portions 22 are sequentially arranged at intervals around the circumference of the rotating housing 2. The number of the positioning and mating portions 22 is equal to the number of the eyepiece mounting cylinders 21. In a state where the rotating housing 2 rotates around the main housing 1, each positioning and mating portion 22 is sequentially snap-fitted with the corresponding positioning portion 14. The settings of each positioning and mating portion 22 respectively form a gear position. During the rotation of the rotating housing 2, the positioning portion 14 is sequentially inserted into the corresponding positioning and mating portion 22 to switch to the corresponding gear position.

[0060] In some possible embodiments, the positioning portion 14 includes an elastic piece. One end of the elastic piece is connected to the main housing 1, and a protrusion is provided at the other end of the elastic piece. The positioning and mating portion 22 includes a groove provided on the inner wall of the rotating housing 2. In a state where the rotating housing 2 rotates around the main housing 1, the protrusion can be sequentially inserted into each groove. When the protrusion is inserted into a groove, when the external force is large enough, the rotating housing 2 can continue to rotate, causing the protrusion to slide out of the corresponding groove and then slide into another groove.

[0061] In some possible embodiments, a toothed ring portion 23 is provided on the rotating housing 2, and an elastic abutting assembly is provided on the main housing 1. The toothed ring portion 23 is sleeved on the rotating housing 2, and the elastic abutting assembly abuts against the toothed ring portion 23.

[0062] A sunk groove 17 can be provided on the main housing 1. A spring and a hard pressing block can be installed in the sunk groove 17. The spring abuts against the hard pressing block, and the hard pressing block abuts against the toothed ring portion 23. During the rotation of the rotating housing 2, the hard pressing block and the convex teeth of the toothed ring portion 23 move relative to each other, generating a vibrating sound and improving the user experience.

[0063] In some possible embodiments, the eyepiece assembly includes a limiting member 3. A retaining edge portion 15 is provided on the main housing 1. The limiting member 3 is detachably connected to the main body, and the rotating housing 2 is limited between the limiting member 3 and the retaining edge portion 15. The limiting member 3 can be a cover structure, which is convenient to be sleeved on the main housing 1.

[0064] This application also provides an optical mirror, which includes: a main body and the above-mentioned eyepiece assembly. The main body has an objective lens. The eyepiece assembly is connected to the main body, and the external light passing through the objective lens can enter the incident channel 11 of the eyepiece assembly. The main body may include a lens barrel and an objective lens provided on the lens barrel. One end of the main housing 1 facing away from the limiting member 3 is provided with a connecting cylinder, and the inner side of the connecting cylinder has the above-mentioned incident channel. The connecting cylinder can be connected to the lens barrel. The connecting cylinder can be detachably connected to the lens barrel of the main body, or the connecting cylinder and the lens barrel of the main body can be an integral structure, that is, the connecting cylinder and the lens barrel of the main body are integrally formed.
