Description

Technical Field

[0001] This utility model relates to the field of telescope technology, and in particular to a novel telescope. Background Technology

[0002] In the existing technology, most users carrying binoculars need to manually and frequently adjust the focus of the binoculars or change the position of the eyepiece in order to obtain a clear image of the target object, which greatly affects the user experience. Summary of the Invention

[0003] This invention aims to at least partially solve one of the problems existing in the prior art. To this end, this invention proposes a novel telescope with a simple structure that allows the telescope to quickly switch between focus-free and fine-tuning modes, thereby effectively improving the user experience.

[0004] The above objective is achieved through the following technical solution:

[0005] A new type of telescope includes:

[0006] Two cylindrical bodies are arranged symmetrically on the left and right sides. An objective lens is fixedly installed at the front end of each cylindrical body, and an eyepiece is provided at the rear end of each cylindrical body.

[0007] A diopter handwheel is provided on the end of the cylinder near the eyepiece to adjust the focal length of the eyepiece;

[0008] A central handwheel is provided, and an eyepiece link seat is movably provided at the midpoint between each cylinder and the diopter handwheel. The central handwheel is connected to two of the eyepiece link seats respectively. The central handwheel drives the two eyepiece link seats to move in the axial direction to adjust the focal length of the eyepiece.

[0009] Adjustment markers are set on the outer wall of the diopter handwheel. On the outer peripheral walls of the two eyepiece connecting seats, symmetrically arranged in opposite directions along the circumferential direction are a hyperopia compensation direction point, a zero-degree marker point, and a myopia compensation direction point. Rotation of the diopter handwheel aligns the adjustment markers with the hyperopia compensation direction points, causing the eyepiece to shift in the hyperopia compensation direction. This causes the focal point of the objective lens to coincide with the focal point of the eyepiece, achieving focus-free adjustment. Alternatively, aligning the adjustment markers with the zero-degree marker point causes the eyepiece to perform a reset movement. The coordinated action of the central handwheel then causes the focal point of the objective lens to coincide with the focal point of the eyepiece, achieving fine-tuning.

[0010] In some embodiments, a negative lens is also included, which is detachably disposed on the end of the tube near the eyepiece. When the adjustment mark point corresponds to the farsightedness compensation direction point, the focal length of the objective lens is adjusted so that the focal point of the objective lens coincides with the focal point of the eyepiece, thereby fixing the objective lens in the tube.

[0011] In some embodiments, when the adjustment mark corresponds to the zero-degree mark, the eyepiece is displaced by zero distance to restore it to the zero-degree reference position.

[0012] In some embodiments, when the adjustment mark point corresponds to the hyperopia compensation direction point, the displacement distance of the eyepiece from the zero-degree reference position to the hyperopia compensation direction is 1.4 mm to 1.6 mm.

[0013] In some embodiments, when the adjustment mark point corresponds to the hyperopia compensation direction point, the displacement distance of the eyepiece from the zero-degree reference position to the hyperopia compensation direction is 1.5 mm.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of the claimed invention.

[0021] Example:

[0022] like Figure 1 and 2 As shown, this embodiment provides a novel telescope, comprising:

[0023] Two cylindrical bodies, 1 arranged symmetrically on the left and right, with an objective lens 2 fixedly installed at the front end of each cylindrical body 1 and an eyepiece 3 installed at the rear end of each cylindrical body 1.

[0024] A diopter handwheel 4 is located on the end of the cylinder 1 near the eyepiece 3 to adjust the focus of the eyepiece 3.

[0025] The central handwheel 5 is movably provided with an eyepiece link 51 at the middle position between each cylinder 1 and the diopter handwheel 4. The central handwheel 5 is connected to the two eyepiece link 51 respectively. The central handwheel 5 drives the two eyepiece link 51 to move in the axial direction to adjust the focal length of the eyepiece 3.

[0026] Adjustment mark 6 is set on the outer wall of the diopter handwheel 4. On the outer peripheral walls of the two eyepiece connecting seats 51, there are symmetrically arranged hyperopia compensation direction point 11, zero-degree mark point 12, and myopia compensation direction point 13 in opposite directions along the circumferential direction. By rotating the diopter handwheel 4, the adjustment mark 6 is aligned with the hyperopia compensation direction point 11, thereby moving the eyepiece 3 in the hyperopia compensation direction, so that the focal point of the objective lens 2 coincides with the focal point of the eyepiece 3 to achieve the purpose of no-focus adjustment. Alternatively, the adjustment mark 6 is aligned with the zero-degree mark point 12 to move the eyepiece 3 to a reset movement. With the cooperation of the central handwheel 5, the focal point of the objective lens 2 coincides with the focal point of the eyepiece 3 to achieve the purpose of fine focusing.

[0027] In this embodiment, the telescope has both focus-free and fine-tuning functions, allowing users to quickly adjust the focus during operation. Its simple structure enables the telescope to switch quickly between focus-free and fine-tuning modes, thereby effectively improving the user experience.

[0028] In this embodiment, since an objective lens 2 is fixedly mounted at the front end of each tube 1 and an eyepiece 3 is provided at the rear end of each tube 1, a diopter wheel 4 is provided at one end of each tube 1 near the eyepiece 3. The diopter wheel 4 is rotated by external force to adjust the focal length of the eyepiece 3. An eyepiece connecting seat 51 is movably provided at the middle position between each tube 1 and the diopter wheel 4. The left and right ends of the central handwheel 5 are respectively connected to the two eyepiece connecting seats 51. The central handwheel 5 is rotated by external force, thus adjusting the focal length of the eyepiece 3. Handwheel 5 drives the two eyepiece connecting seats 51 to move axially to adjust the focal length of the two eyepieces 3 synchronously. The diopter handwheel 4 has adjustment mark points 6 on the outer peripheral wall near one end of the eyepiece connecting seat 51. On the outer peripheral wall of each eyepiece connecting seat 51, a farsightedness compensation direction point 11, a zero-degree mark point 12, and a nearsightedness compensation direction point 13 are arranged sequentially along the circumference. The farsightedness compensation direction points 11, zero-degree mark points 12, and nearsightedness compensation points 13 on the two eyepiece connecting seats 51 are arranged symmetrically in opposite directions, which facilitates the user's operation.

[0029] In this embodiment, by driving the diopter handwheel 4 to rotate, the adjustment mark 6 is aligned with the farsightedness compensation direction point 11, causing the eyepiece 3 to shift a certain distance in the farsightedness compensation direction. This causes the focal point of the objective lens 2 to coincide with the focal point of the eyepiece 3, thus enabling the telescope to achieve focus-free operation. This allows the current telescope to meet the user's maximum clear viewing range of 20m to infinity. Alternatively, by aligning the adjustment mark 6 with the zero-degree mark 12, the eyepiece 3 is reset, i.e., the displacement distance of the eyepiece 3 is returned to zero. Then, by driving the central handwheel 5 to rotate, the focal length of both eyepieces 3 is adjusted simultaneously until the focal point of the objective lens 2 coincides with the focal point of the eyepiece 3, achieving fine-tuning. This allows the current telescope to meet the user's maximum clear viewing range of 2m to infinity. This allows the telescope to switch between focus-free and fine-tuning modes, thereby improving the user experience.

[0030] In this embodiment, since the two tubes 1 are symmetrically arranged to form a binocular telescope, the internal structure of each tube 1 is the same. The difference is that the farsightedness compensation direction point 11, the zero degree mark point 12, and the nearsightedness compensation direction point 13 on the two tubes 1 are arranged in opposite directions. Specifically, on the left tube 1, the farsightedness compensation direction point 11, the zero degree mark point 12, and the nearsightedness compensation direction point 13 are arranged alternately from left to right at the upper position of the left tube 1. Similarly, on the right tube 1, the farsightedness compensation direction point 11, the zero degree mark point 12, and the nearsightedness compensation direction point 13 are arranged alternately from right to left at the upper position of the right tube 1. This can improve the user experience.

[0031] Furthermore, it also includes a negative lens, which is detachably mounted on one end of the tube 1 near the eyepiece 3. When the adjustment mark 6 corresponds to the farsightedness compensation direction point 11, the focal length of the objective lens 2 is adjusted so that the focal point of the objective lens 2 coincides with the focal point of the eyepiece 3, thereby fixing the objective lens 2 inside the tube 1.

[0032] In this embodiment, the telescope's objective lens focal length is calibrated before leaving the factory. Since the eyepiece 3 has zero displacement distance when at the zero-degree reference position, the diopter wheel 4 is first rotated by external force to adjust the focal length of the eyepiece 3. The rotation of the diopter wheel 4 causes the eyepiece 3 to move in the direction of farsightedness compensation until the adjustment mark 6 on the diopter wheel 4 corresponds to the farsightedness compensation direction point 11. Then, the diopter wheel 4 stops rotating. Thus, even if the displacement distance of the eyepiece 3 from the zero-degree reference position to the direction of farsightedness compensation is 1.5mm, the negative lens is then detachably fitted onto the end of the tube 1 near the eyepiece 3. The focal length of the objective lens 2 is then adjusted until the focal point of the objective lens 2 coincides with the focal point of the eyepiece 3. This confirms the focal length of the objective lens 2. The objective lens 2 is then fixedly installed inside the tube 1. This allows the user to achieve the effect of no-focusing or fine-tuning by adjusting the focal length of the eyepiece 3 during operation.

[0033] Preferably, when the adjustment mark 6 corresponds to the zero-degree mark 12, the displacement distance of the eyepiece 3 is zero so that it returns to the zero-degree reference position.

[0034] Specifically, when the adjustment mark 6 corresponds to the hyperopia compensation direction point 11, the displacement distance of the eyepiece 3 from the zero-degree reference position to the hyperopia compensation direction is 1.4mm to 1.6mm.

[0035] Specifically, when the adjustment mark 6 corresponds to the hyperopia compensation direction point 11, the eyepiece 3 is displaced 1.5 mm from the zero-degree reference position in the hyperopia compensation direction.

[0036] In this embodiment, since the displacement distance of the eyepiece 3 is zero when it is at the zero-degree reference position, specifically, when the adjustment mark point 6 corresponds to the zero-degree mark point 12, the displacement distance of the eyepiece 3 is zero to restore it to the zero-degree reference position. When the adjustment mark point 6 corresponds to the hyperopia compensation direction point 11, the displacement distance of the eyepiece 3 from the zero-degree reference position to the hyperopia compensation direction is 1.4mm to 1.6mm, thereby performing hyperopia compensation on the eyepiece 3. Preferably, the displacement distance of the eyepiece 3 from the zero-degree reference position to the hyperopia compensation direction is 1.4mm to 1.6mm. When the adjustment mark point 6 corresponds to the myopia compensation direction point 13, the displacement distance of the eyepiece 3 from the zero-degree reference position to the myopia compensation direction is 1.4mm to 1.6mm, thereby performing myopia compensation on the eyepiece 3. Preferably, the displacement distance of the eyepiece 3 from the zero-degree reference position to the hyperopia compensation direction is 1.5mm.

[0037] In this embodiment, when the user needs to fine-tune the focus during operation, the diopter handwheel 4 is first driven to rotate by external force until the adjustment mark 6 corresponds to the zero-degree mark 12. Then, the diopter handwheel 4 stops rotating, thereby driving the eyepiece 3 to reset by rotating the diopter handwheel 4, so that the displacement distance of the eyepiece 3 is zero, so that it returns to the zero-degree reference position. Then, the action of the central handwheel 5 drives the eyepiece connecting seat 51 to move along the axial direction to simultaneously adjust the focal length of the two eyepieces until the focal point of the objective lens 2 coincides with the focal point of the eyepiece 3, thereby achieving the purpose of fine-tuning the focus of the telescope. In this way, the current telescope can meet the user's maximum range of clear observation from 2m to infinity.

[0038] During operation, if the user needs to switch the telescope from fine-tuning to focus-free mode, the central handwheel 5 is rotated by external force to move the eyepiece link 51 axially, thus resetting the eyepiece link 51. Then, the diopter handwheel 4 is rotated by external force to adjust the focal length of the eyepiece 3 until the adjustment mark 6 on the diopter handwheel 4 corresponds to the farsightedness compensation direction point 11. The diopter handwheel 4 then stops rotating, causing the eyepiece 3 to shift 1.5mm from the zero-degree reference position towards the farsightedness compensation direction. This allows the focal point of the objective lens 2 to coincide with the focal point of the eyepiece 3, achieving focus-free operation. This allows the telescope to provide a maximum viewing range of 20m to infinity, enabling most users to directly and clearly observe targets. This allows the telescope to switch between focus-free and fine-tuning modes, improving the user experience.

[0039] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
