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 a visual optical instrument used to observe distant objects. A telescope hinge is a hinge mechanism used to connect the two tubes of a telescope. It is usually connected by a hinge axis that serves as a reference. The tubes can rotate around the hinge axis to change the distance between the two eyepieces so that it can be adapted to the interpupillary distance of the observer's two eyes.

[0003] A search revealed that the publication number is CN221200097U, entitled "A Telescope Hinge Structure and a Telescope," which includes two telescope tubes with a first lug and a second lug on each tube. Research and analysis revealed that although the structure of this application is more wear-resistant than the traditional method, it still has the following defects to some extent.

[0004] For example, the hinge and lens barrel of the aforementioned telescope are integrally molded, making it inconvenient to disassemble and assemble them. This means that when the hinge or lens barrel is damaged, it cannot be replaced individually, but the entire structure must be replaced, increasing maintenance and replacement costs. Furthermore, it is not possible to quickly disassemble the binoculars into a monocular, resulting in poor practicality. Additionally, the hinge cannot be continuously lubricated, leading to wear at the sliding connection points and affecting the hinge's lifespan. To solve these technical problems, we have designed a new telescope hinge structure and a new telescope. Utility Model Content

[0005] The purpose of this utility model is to provide a telescope hinge structure and a telescope, which has the advantages of easy disassembly, easy replacement of the telescope barrel or hinge, reducing replacement costs, and continuous lubrication of the hinge to extend service life. It solves the problems of inconvenience in disassembling the telescope barrel and hinge, inability to replace the telescope barrel and hinge individually, increased replacement costs, and inability to continuously lubricate the hinge, which affects service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a telescope hinge structure and a telescope, including a telescope tube body, wherein there are two telescope tube bodies, a connecting plate is inserted into the inner side of the telescope tube body, a central shaft is slidably sleeved in the inner cavity of the connecting plate, a storage groove is opened in the middle of the top of the connecting plate, a sponge pad is placed in the inner cavity of the storage groove, an oil drain hole is opened at the bottom of the inner cavity of the storage groove, a mounting plate is fixedly connected to the outer side of the connecting plate, a positioning mechanism is provided on the inner side of the telescope tube body, the positioning mechanism includes a mounting groove, positioning plates are slidably connected through the front and rear sides of the inner cavity of the mounting groove, and a positioning spring is fixedly connected between the front and rear positioning plates.

[0007] Preferably, mounting slots are provided on both the front and rear sides of the inner side of the lens barrel, and the outer side of the positioning plate extends through the inner cavity of the mounting slot.

[0008] Preferably, the top of the storage slot is equipped with a cover plate, the top of the cover plate has an oil injection hole, and a rubber plug is inserted into the top of the oil injection hole.

[0009] Preferably, a placement groove is provided on the inner side of the top of the lens barrel body, a sliding opening is provided at the bottom of the inner cavity of the placement groove, a push plate is fixedly connected to the top of the positioning insert plate through the sliding opening, and a sealing plate is installed on the top of the placement groove.

[0010] Preferably, a locking screw is threaded into the front side of the central shaft, and a mounting bolt is threaded into the rear side of the central shaft.

[0011] Preferably, the surface of the mounting plate is provided with positioning holes, and the number of oil drain holes is several and they are arranged at equal intervals.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. Drip lubricating oil into the sponge pad. When rotating the telescope body on both sides during use, the lubricating oil will flow into the surface of the central axis through the oil drain hole. This lubrication will greatly reduce wear between the surface of the central axis and the connecting plate, effectively extending the service life of the hinge.

[0014] 2. Push the push plates on both sides inward, and the positioning insert will move out of the mounting slot. Pull the telescope body outward. This allows for separate maintenance of the hinge, making maintenance more convenient. It also allows for separate replacement of the telescope body, saving replacement costs. At the same time, the disassembled telescope body can be used as a monocular telescope, improving its practicality. Attached Figure Description

[0020] Please see Figures 1-4 A telescope hinge structure and a telescope, including a telescope tube body 1, of which there are two. A connecting plate 2 is inserted into the inner side of the telescope tube body 1. A central shaft 7 is slidably sleeved in the inner cavity of the connecting plate 2. A storage groove 9 is opened in the middle of the top of the connecting plate 2. A sponge pad 10 is placed in the inner cavity of the storage groove 9. By setting the sponge pad 10, the lubricating oil can be stored for a long time by means of water absorption, avoiding rapid flow to the surface of the central shaft 7. An oil drain hole 14 is opened at the bottom of the inner cavity of the storage groove 9. An installation plate 6 is fixedly connected to the outer side of the connecting plate 2. A positioning mechanism 15 is set in the inner side of the telescope tube body 1. The positioning mechanism 15 includes an installation groove 18. Positioning plates 16 are slidably connected through the front and rear sides of the inner cavity of the installation groove 18. A positioning spring 17 is fixedly connected between the front and rear positioning plates 16. By setting the positioning spring 17, the positioning plate 16 can be pushed through the installation plate 6 by releasing the elastic force to fix the connecting plate 2, making the installation more convenient and efficient.

[0021] Please see Figure 4 The front and rear sides of the inner side of the lens barrel body 1 are provided with mounting slots 5. By setting the mounting slots 5, the mounting plate 6 can be easily inserted and limited. The outer side of the positioning plate 16 extends into the inner cavity of the mounting slot 5.

[0022] Please see Figure 3 The top of the storage slot 9 is equipped with a cover plate 13. By setting the cover plate 13, the top of the storage slot 9 can be sealed. The top of the cover plate 13 is provided with an oil injection hole 11. By setting the oil injection hole 11, lubricating oil can be injected into the storage slot 9 after removing the rubber plug 12. The top of the oil injection hole 11 is inserted with a rubber plug 12. By setting the rubber plug 12, the oil injection hole 11 can be easily sealed to prevent the internal lubricating oil from flowing out.

[0023] Please see Figure 4The inner side of the top of the lens barrel body 1 is provided with a placement groove 20. The bottom of the inner cavity of the placement groove 20 is provided with a sliding opening. By providing the sliding opening, the push plate 19 can easily push the positioning insert 16 to move back and forth. The top of the positioning insert 16 passes through the sliding opening and is fixedly connected to the push plate 19. A sealing plate 3 is installed on the top of the placement groove 20. By providing the sealing plate 3, the opening of the placement groove 20 can be sealed to prevent dust and other debris from entering and affecting its use.

[0024] Please see Figure 2 The front side of the central shaft 7 is threaded with a locking screw 4, and the rear side of the central shaft 7 is threaded with a mounting bolt 8.

[0025] Please see Figure 3 The mounting plate 6 has positioning holes on its surface. By setting the positioning holes, the positioning plate 16 can easily pass through the mounting plate 6 to position it. There are several oil drain holes 14, which are arranged at equal intervals.

[0026] In use, place the sponge pad 10 inside the storage slot 9 and drip lubricating oil onto the surface of the sponge pad 10, then cover it with the cover plate 13. During the use of the telescope, when the two sides of the telescope tube body 1 are rotated, the lubricating oil drawn into the sponge pad 10 will flow into the surface of the central axis rod 7 through the oil drain hole 14. After the surface of the central axis rod 7 and the connecting plate 2 are lubricated, wear will be greatly reduced, effectively extending the service life of the hinge. When the hinge fails, pry open the sealing plates 3 on both sides, and then push the push plates 19 on both sides inward at the same time. The positioning insert plate 16 will move out of the mounting slot 5. At this time, the telescope tube body 1 can be pulled outward to complete the disassembly. This allows for individual repair of the hinge, making repair more convenient, and also allows for individual replacement of the telescope tube body 1, saving replacement costs. At the same time, the disassembled telescope tube body 1 can be used as a monocular telescope, improving its practicality.

[0027] In summary, this telescope hinge structure and telescope, through the coordinated use of the telescope tube body 1, connecting plate 2, mounting slot 5, mounting insert plate 6, storage slot 9, sponge pad 10, oil drain hole 14 and positioning mechanism 15, solve the problems of inconvenience in disassembling the telescope tube and hinge, inability to replace the telescope tube and hinge individually, increased replacement costs, and inability to continuously lubricate the hinge, thus affecting its service life.
