These terms are mainly used to distinguish one element from another element, or from one signal to another signal. In addition, the term "or" as used herein should be taken to include any one or combination of more of the associated listed items as the case may be.

Please refer to fig. 1 to 7, which illustrate an embodiment of the present application. The embodiment discloses a monocular telescope 100, in particular an astronomical telescope; that is, any telescope that is not a monocular is different from the monocular telescope 100 of the present embodiment. As shown in fig. 1 to 4, the monocular telescope 100 includes a housing module 1, a lens barrel module 2 movably mounted in the housing module 1, and a camera 3 fixed to the housing module 1.

It should be noted that the housing module 1 and the lens barrel module 2 may be referred to as an adjustable optical mechanism in this embodiment, and the adjustable optical mechanism is described in this embodiment by being associated with the camera 3, but the present application is not limited thereto. For example, in other embodiments not shown, the adjustable optical mechanism can be used alone (e.g., sold) or in combination with other components.

As shown in fig. 3 to 5, the housing module 1 includes an outer cylinder 11 and a manipulating assembly 12 mounted on the outer cylinder 11 (outer surface). In this embodiment, the outer cylinder 11 is substantially tubular and defines a center line L; that is, any cross section of the outer cylinder 11 perpendicular to the center line L is a circular ring with its center located on the center line L. Furthermore, the outer cylinder 11 has an observing end 111 and a mounting end 112 at two opposite ends, and the outer diameter of the observing end 111 is larger than that of the mounting end 112.

In more detail, the outer cylinder 11 is formed with a mounting groove 114 communicating with the inner space 113 thereof; that is, the inner space 113 of the outer cylinder 11 can communicate with an outer space through the mounting groove 114. In this embodiment, the mounting groove 114 is located at a position of the outer cylinder 11 substantially at the center of the observing end 111 and the mounting end 112.

The manipulation assembly 12 is located between the observation end 111 and the mounting end 112; that is, the manipulation assembly 12 is mounted at a portion of the outer cylinder 11 (e.g., the mounting groove 114) located at a substantially center of the observing end 111 and the mounting end 112. In the present embodiment, the control assembly 12 includes a rotating shaft 121 perpendicular to the center line L and two manual knobs 122 respectively mounted at two ends of the rotating shaft 121.

In more detail, the rotating shaft 121 is formed with a plurality of gear teeth 123, and the plurality of gear teeth 123 are located at a substantially center of the rotating shaft 121 and within the mounting groove 114. At least one of the plurality of gear teeth 123 may be located in the inner space 113 of the outer cylinder 11 through the mounting groove 114. Any one of the manual knobs 122 can be operated to rotate so as to drive the rotating shaft 121 to rotate, and then the plurality of gear teeth 123 pass through the mounting groove 114 in turn.

However, although the operation control assembly 12 is illustrated in the embodiment by the rotating shaft 121 and the two manual knobs 122, the application is not limited thereto. For example, in other embodiments not shown in the present application, the manipulating assembly 12 may also include the rotating shaft 121 and a semi-automatic mechanism engaged with the rotating shaft 121.

As shown in fig. 3 to 5, the lens barrel module 2 is movably mounted in the outer cylinder 11, and the lens barrel module 2 can move (by cooperating with the manipulating component 12) reciprocally in a first position (fig. 6) and a second position (fig. 7) relative to the housing module 1, and the camera 3 is fixed at the mounting end 112 of the outer cylinder 11 and located on the central line L. In this embodiment, the relative position between the camera 3 and the outer cylinder 11 is kept fixed (e.g., the camera 3 is locked to the outer cylinder 11), so that the monocular telescope 100 can adopt a heavier camera 3; for example: the weight of the camera 3 is 20% to 45% of the total weight of the housing module 1 and the lens barrel module 2, or the weight of the camera 3 is 2.5 kilograms (kg) to 4.5 kg, but the application is not limited thereto.

The lens barrel module 2 includes an inner cylinder 21 located in the outer cylinder 11, a plurality of optical lenses 22 fixed in the inner cylinder 21 at intervals, and a rack 23 fixed to the inner cylinder 21 and engaged with the control assembly 12. It should be noted that the relative positions of the optical lenses 22 and the inner cylinder 21 are limited to be kept constant in this embodiment, so as to exclude any lens and cylinder that may generate relative movement.

The inner cylinder 21 has a first end 211 and a second end 212 respectively located at two opposite ends, and the second end 212 is closer to the mounting end 112 than the first end 211, and an annular gap G is formed between the inner cylinder 21 and the outer cylinder 11 and communicates with the mounting groove 114. Furthermore, the relative positions of the optical lenses 22 are kept fixed (i.e., the optical lenses 22 do not move relative to each other), and the optical lenses 22 define a central optical axis C overlapping the central line L in the present embodiment.

In more detail, the inner cylinder 21 in this embodiment includes a first cylinder 21a and a second cylinder 21b connected to the first cylinder 21a, and a first inner diameter of the first cylinder 21a is different from a second inner diameter of the second cylinder 21b (e.g., the first inner diameter is larger than the second inner diameter).

Wherein, the end edge of the first cylinder 21a far away from the second cylinder 21b is defined as the first end 211, and the end edge of the second cylinder 21b far away from the first cylinder 21a is defined as the second end 212; that is, the second cylinder 21b is closer to the camera 3 than the first cylinder 21 a. It should be additionally noted that the relative positions of the first cylinder 21a and the second cylinder 21b are kept unchanged in the present embodiment.

The optical lenses 22 are fixed in the first cylinder 21a and the second cylinder 21b, respectively. Further, the plurality of optical lenses 22 includes at least one first lens 22a installed in the first cylinder 21a and at least one second lens 22b installed in the second cylinder 21b, and a radius of at least one of the first lenses 22a is larger than a radius of at least one of the second lenses 22 b.

Accordingly, the inner cylinder 21 in the present embodiment includes a plurality of sub-cylinders (e.g., the first cylinder 21a and the second cylinder 21b) for mounting the optical lenses 22 with different radii, so that the monocular telescope 100 can meet different design requirements.

In addition, the inner cylinder 21 is illustrated as a structure including a plurality of sub-cylinders (e.g., the first cylinder 21a and the second cylinder 21b) in the embodiment, but the disclosure is not limited thereto. For example, in other embodiments not shown in the present application, the inner cylinder 21 may also be a one-piece structure formed integrally, and the optical lenses 22 may also have the same radius.

In the present embodiment, the rack 23 is fixed on the outer surface of the inner cylinder 21 (e.g., the first cylinder 21a) and located in the annular gap G, and the rack 23 is long and the length direction thereof is parallel to the central optical axis C. Wherein the rack 23 is positioned corresponding to the mounting groove 114 such that at least one of the plurality of gear teeth 123 is engaged with the rack 23. Accordingly, the mounting position of the rack 23 utilizes the annular gap G between the inner cylinder 21 and the outer cylinder 11, thereby effectively reducing the adjustment range of the inner cylinder 21 and the outer cylinder 11 required when the rack 23 is additionally provided.

Further, the steering assembly 12 can drive the rack 23 (via the two manual knobs 122 and the rotating shaft 121) to move the lens barrel module 2 reciprocally with respect to the housing module 1 along a direction parallel to the central optical axis C, so that the camera 3 can be used to focus on an object (not shown), such as a star. Accordingly, the monocular telescope 100 can adjust the position of the lens barrel module 2 relative to the camera 3 by the engagement of the rack 23 and the steering assembly 12, so that the camera 3 does not need to be moved, thereby facilitating the focusing operation.

When the lens barrel module 2 is located at the first position (see fig. 6), the lens barrel module 2 is adjacent to the camera 3 and is separated from the observation end 111 by a first light shielding depth D1, which is 40% to 50% of the length of the housing module 1. Furthermore, when the lens barrel module 2 is located at the second position (see fig. 7), the lens barrel module 2 is far away from the camera 3 and is separated from the observation end 111 by a second light shielding depth D2, which is 35% to 45% of the length of the housing module 1, and the second light shielding depth D2 is smaller than the first light shielding depth D1. Accordingly, in the present embodiment, the single-tube telescope 100 is configured by the structure of the outer tube 11 and the lens barrel module 2, so that the outer tube 11 can ensure sufficient light shielding effect during the movement of the lens barrel module 2, thereby facilitating the focusing operation.

In summary, the monocular telescope and the adjustable optical mechanism thereof disclosed in the embodiments of the present application adjust the position of the lens barrel module relative to the camera through the cooperation of the rack and the control assembly, so that the camera does not need to be moved, thereby facilitating the focusing operation precisely, and allowing the monocular telescope to adopt a heavier camera (for example, the weight of the camera is 20% to 45% of the total weight of the housing module and the lens barrel module).

In addition, the single-tube telescope disclosed in the embodiment of the present application uses the annular gap between the inner tube and the outer tube to mount the rack, so as to effectively reduce the adjustment range of the inner tube and the outer tube required when the rack is additionally arranged.

In addition, according to the single-tube telescope disclosed by the embodiment of the application, through the structural matching of the outer tube body and the lens cone module (for example, the first shading depth is 40% -50% of the length of the outer shell module, and the second shading depth is 35% -45% of the length of the outer shell module), the outer tube body can ensure a sufficient shading effect in the moving process of the lens cone module, so that the focusing operation can be accurately performed.

The disclosure is only a preferred embodiment and is not intended to limit the scope of the claims, so that all equivalent variations using the teachings of the present specification and drawings are included in the scope of the claims.
