Description

Technical Field

[0001] This utility model relates to the field of telescope technology, specifically a telescope hinge structure and a telescope. Background Technology

[0002] A telescope is an optical instrument that uses lenses or mirrors and other optical components to observe distant objects. It works by using the refraction of light through a lens or the reflection of light by a concave mirror to make the light enter a small aperture and converge to form an image, which is then seen through a magnifying eyepiece. It is also known as a "telescope".

[0003] The hinge structure is a key component affecting the user experience and stability of a telescope. Most existing telescope hinge structures adopt a fixed resistance design, meaning that the adjustment resistance cannot be changed after manufacturing. If the resistance is set too high, it will make it difficult for users to adjust the telescope tube angle, affecting the ease of use. If the resistance is set too low, although adjustment is easy, the hinge structure is prone to loosening due to frequent rotation and shaking of the telescope during long-term use, affecting the use of the telescope.

[0004] To solve the above technical problems, it is necessary to design a telescope hinge structure and a telescope to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a telescope hinge structure and a telescope, which has the advantages of maintaining hinge damping stability and effectively preventing hinge structure loosening. It solves the problem that the existing telescope hinge structure adopts a fixed resistance design, the hinge resistance cannot be adjusted, and the hinge is prone to loosening in subsequent use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a telescope hinge structure, including a support tube, on the surface of which a disc and a horizontal plate are respectively fitted, a threaded rod is movably connected to the inner cavity of the support tube, and movable plates are threadedly fitted on both the front and rear sides of the surface of the threaded rod. A compression tube is fixedly connected to both sides of the movable plate, a spring is fixedly connected to one side of the compression tube, and a compression ring is fixedly connected to one side of the spring. The side of the compression ring away from the spring contacts the horizontal plate, and the compression tube, spring, and compression ring are all fitted on the surface of the support tube.

[0007] Preferably, the disc is fixedly connected to the support tube, the support tube is movably connected to the horizontal plate, and the surface of the horizontal plate is adhered with an anti-slip pad.

[0008] Preferably, the threads on the front and rear sides of the threaded rod surface are in opposite directions, and a knob is fixedly connected to the front end of the threaded rod.

[0009] Preferably, guide holes are provided on both sides of the support tube, and both sides of the movable plate pass through the guide holes and are movably connected to the guide holes.

[0010] Preferably, the surface of the disc is provided with a scale groove, and a pointer is fixedly connected to the bottom of the horizontal plate.

[0011] A telescope includes a telescope tube, a movable tube extending through the front side of the telescope tube, an objective lens embedded in the rear side of the inner cavity of the telescope tube, an eyepiece embedded in the front side of the movable tube, a connecting plate fixedly connected to the surface of the movable tube, a connecting ring fixedly connected to the side of the connecting plate away from the movable tube, a threaded sleeve extending through the center of the connecting ring, the threaded sleeve being fitted onto the surface of a supporting tube, and the threaded sleeve being rotatably connected to the connecting ring.

[0012] Preferably, the threaded sleeve is threadedly connected to the support pipe, and the surface of the threaded sleeve is fixedly connected with anti-slip protrusions.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a threaded rod, a movable plate, a compression tube, a spring, and a compression ring inside the support tube, can drive two movable plates to move towards or away from each other, thereby changing the compression force of the compression ring on the horizontal plate, and realizing the adjustment of increasing or decreasing the rotational resistance of the hinge structure. This allows users to flexibly adjust the resistance of the telescope tube rotation according to their own needs and usage scenarios, ensuring both ease and convenience of adjustment, and effectively avoiding loosening problems caused by long-term use, thus improving the stability and imaging quality of the telescope.

[0015] 2. This utility model, by setting up a telescope tube, a movable tube, an objective lens, an eyepiece, a connecting plate, a connecting ring, and a threaded sleeve, enables the movable tube to move laterally and adjust the length of the movable tube extending out of the telescope tube, thereby adjusting the distance between the eyepiece and the objective lens.

[0020] Please see Figures 1-3 A telescope hinge structure includes a support tube 1, with a disc 2 and a horizontal plate 3 respectively fitted on the surface of the support tube 1. A threaded rod 4 is movably connected to the inner cavity of the support tube 1. Moving plates 6 are threadedly fitted on both the front and rear sides of the surface of the threaded rod 4. Compression tubes 7 are fixedly connected to both sides of the moving plates 6. A spring 8 is fixedly connected to one side of the compression tube 7, and a compression ring 9 is fixedly connected to one side of the spring 8. The side of the compression ring 9 away from the spring 8 contacts the horizontal plate 3. The compression tubes 7, springs 8, and compression rings 9 are all fitted on the surface of the support tube 1. By setting the threaded rod 4, moving plates 6, compression tubes 7, springs 8, and compression rings 9 inside the support tube 1, the two moving plates 6 can be driven to move towards or away from each other, thereby changing the compression force of the compression ring 9 on the horizontal plate 3. This allows for adjustment of the rotational resistance of the hinge structure, enabling users to flexibly adjust the rotational resistance of the telescope tube 14 according to their own needs and usage scenarios. This ensures easy and convenient adjustment and effectively avoids loosening caused by long-term use, improving the stability and imaging quality of the telescope.

[0021] Please see Figure 1 The disc 2 is fixedly connected to the support tube 1, and the support tube 1 is movably connected to the horizontal plate 3. The surface of the horizontal plate 3 is bonded with an anti-slip pad. By setting the support tube 1 and the disc 2, a stable reference and support point is provided for the entire hinge structure, ensuring that the position of the disc 2 is fixed during the use of the telescope and will not move due to the rotation of the lens tube 14. The anti-slip pad increases the friction between the horizontal plate 3 and the disc 2, providing damping support for the horizontal plate 3 and the lens tube 14.

[0022] Please see Figure 3 The threads on the front and rear sides of the threaded rod 4 have opposite directions. A knob 10 is fixedly connected to the front end of the threaded rod 4. By setting the knob 10, the contact area with the hand is increased, which makes it easier to drive the threaded rod 4 to rotate. The rotation angle of the threaded rod 4 can be controlled more precisely, thereby accurately controlling the moving distance of the moving plate 6 and the squeezing force of the squeezing ring 9, and realizing fine adjustment of the rotation resistance.

[0023] Please see Figure 3Guide holes 11 are provided on both sides of the support tube 1. Both sides of the moving plate 6 pass through the guide holes 11 and are movably connected to the guide holes 11. The guide holes 11 provide precise guidance for the movement of the moving plate 6, so that the moving plate 6 can only move in a straight line along the direction of the guide holes 11, avoiding the moving plate 6 from deviating or shaking during the movement, ensuring the thread fit accuracy between the moving plate 6 and the threaded rod 4, and improving the stability and reliability of the entire adjustment mechanism.

[0024] Please see Figure 1 The surface of the disc 2 is provided with a scale groove 12, and the bottom of the horizontal plate 3 is fixedly connected to a pointer 13. By setting the scale groove 12 and the pointer 13, a precise angle measurement function is formed. When adjusting the angle of the telescope tube 14, the user can accurately grasp the rotation angle of the telescope tube 14 by observing the position of the pointer 13 on the scale groove 12, thereby achieving precise control of the telescope's observation direction and greatly improving the accuracy and efficiency of observation.

[0025] Please see Figures 1-3 A telescope includes a tube 14, a movable tube 15 extending through the front of the tube 14, an objective lens 16 embedded in the rear of the inner cavity of the tube 14, an eyepiece 17 embedded in the front of the movable tube 15, a connecting plate 18 fixedly connected to the surface of the movable tube 15, a connecting ring 19 fixedly connected to the side of the connecting plate 18 away from the movable tube 15, a threaded sleeve 20 extending through the center of the connecting ring 19, the threaded sleeve 20 being fitted onto the surface of a support tube 1, and the threaded sleeve 20 being rotatably connected to the connecting ring 19. By configuring the tube 14, movable tube 15, objective lens 16, eyepiece 17, connecting plate 18, connecting ring 19, and threaded sleeve 20, the movable tube 15 can be moved laterally, adjusting the length of the movable tube 15 extending out of the tube 14, thereby adjusting the distance between the eyepiece 17 and the objective lens 16. This can meet the needs of different users for telescope focal length adjustment, adapting to observation targets of different distances and sizes, and improving the applicability and observation effect of the telescope.

[0026] Please see Figure 3 The threaded sleeve 20 is threadedly connected to the support tube 1. The surface of the threaded sleeve 20 is fixedly connected with anti-slip protrusions 5. By setting anti-slip protrusions 5, the friction between the user's hand and the threaded sleeve 20 is increased, allowing the user to control the rotation of the threaded sleeve 20 more easily and accurately, improving the convenience and safety of operation. The design of anti-slip protrusions 5 can ensure that the user can complete the adjustment operation smoothly under various conditions, improving the overall user experience.

[0027] In use, rotating the lens barrel 14 drives the horizontal plate 3 to rotate. The horizontal plate 3 rotates around the support tube 1, adjusting the angle of the lens barrel 14. The horizontal plate 3 also drives the pointer 13 to rotate. Observe the position of the pointer 13 on the scale groove 12 to accurately grasp the rotation angle of the lens barrel 14. Rotating the knob 10 drives the threaded rod 4 to rotate. The threaded rod 4 drives the moving plate 6 to move. The moving plate 6 drives the extrusion tube 7 to move, so that the two extrusion tubes 7 are close to each other to extrude the spring 8. The spring 8 extrudes the horizontal plate 3 through the extrusion ring 9, increasing the rotational resistance between the horizontal plate 3 and the disc 2, and providing tension support for the lens barrel 14 to prevent the lens barrel 14 from loosening.

[0028] The rotating threaded sleeve 20 is threadedly connected to the support tube 1. The threaded sleeve 20 drives the connecting ring 19 and the connecting plate 18 to move. The connecting plate 18 drives the movable tube 15 and the eyepiece 17 to move. Adjusting the distance between the eyepiece 17 and the objective lens 16 allows for a clearer image when observing small objects at a distance. When observing larger objects at close range, the distance can be reduced for easier observation.

[0029] In summary, this telescope hinge structure and telescope, through the threaded rod 4, moving plate 6, compression tube 7, spring 8, and compression ring 9, solve the problem that existing telescope hinge structures use a fixed resistance design, making the hinge resistance unadjustable and prone to loosening during subsequent use.
