Description

Technical Field

[0001] The utility model relates to the technical field of myopia prevention and control design, in particular to a telescope. Background Art

[0002] In myopia prevention and control, the principle of telescopes is mainly to achieve the effect of reflecting and moving the image of close objects away by using two mirrors, usually two concave mirrors. Specifically, after the light is reflected by the objective lens, an enlarged image 2-8 meters farther than the actual distance will be formed behind the eyepiece, or even farther. This design allows the observer to view close objects as if they were distant objects, thereby reducing the burden of eye adjustment, eye stress and eye fatigue.

[0003] At present, when most of the telescopes are used, the height of the eyepiece and the objective lens relative to the reading and writing platform is roughly adjusted manually. However, when a small distance needs to be adjusted, macro adjustment cannot be achieved.

DETAILED DESCRIPTION

[0031] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0032] Embodiment 1

[0033] like Figure 1-Figure 2 , Figure 5-Figure 7 As shown, a zoom lens of this embodiment includes an eyepiece 1 and an objective lens 2 which are hinged to each other, wherein the eyepiece 1 is tilted and has a certain angle with the horizontal plane. The zoom lens also includes a lifting mechanism 3 installed on the back wall of the eyepiece 1 and capable of driving the eyepiece 1 and the objective lens 2 to rise and fall.

[0034] Specifically, the lifting mechanism 3 includes a mounting box 31 and an articulated seat 34, and the articulated seat 34 is fitted with the mounting box 31. A single-axis reduction motor 35 is embedded in the articulated seat 34. Two relatively parallel racks 32 are arranged inside the mounting box 31. A gear set 33 is contained in the mounting box 31 and meshes with the two racks 32. The single-axis reduction motor 35 can drive the gear set 33 to rotate, so that the gear set 33 drives the two racks 32 to move in the same direction, thereby driving the eyepiece 1 and the objective lens 2 to move up and down. By setting the lifting mechanism 3, it is possible to achieve that the height of the eyepiece 1 and the objective lens 2 does not need to be manually adjusted, that is, by setting the rack 32 and the gear set 33, it can be driven by the single-axis reduction motor 35, so that the gear set 33 drives the rack 32 to move up and down, and can stop at any position, thereby realizing the automation of the lifting and lowering of the eyepiece 1 and the objective lens 2. Moreover, through the cooperation between the rack 32 and the gear set 33, it is possible to achieve macro adjustment, that is, by changing the parameters of the rack 32 and the gear set 33, such as the number of teeth, the minimum adjustable distance can be controlled, thereby achieving fine adjustment of the height of the eyepiece 1 and the objective lens 2 relative to the reading and writing platform. Therefore, the zoom lens of the present application can avoid the image reflected by the eyepiece 1 being inconsistent with the expected zoom distance when the error between the height of the eyepiece 1 and the objective lens 2 is large and the expected value, thereby avoiding the zoom lens from failing to achieve the accurate expected zoom distance.

[0035] Furthermore, if Figure 5 As shown, the gear set 33 includes a driving gear 331 and a driven gear 332. The driving gear and the driven gear are arranged transversely to each other and mesh with each other. The two racks 32 are respectively located on the side where the driving gear and the driven gear are away from each other, and are respectively connected to the corresponding driving gear or driven gear. The driving gear is fixedly connected to the output shaft 36 of the single-axis reduction motor 35. The driven gear is fixedly connected to the rotating shaft 37, and is rotatably connected to the articulated seat 34 through the rotating shaft 37. Two strip-shaped long holes are opened on the side wall of the mounting box 31 facing the articulated seat 34, and the output shaft 36 and the rotating shaft 37 pass through the two strip-shaped long holes respectively. The driving gear and the driven gear are driven to rotate by the single-axis reduction motor 35. Since the driving gear and the driven gear are meshed with the two racks 32, the driving gear and the driven gear rotate, driving the two racks 32 to move in the same direction. The racks 32 drive the installation box 31 to move, and the installation box 31 is connected to the back side of the eyepiece 1, thereby driving the eyepiece 1 to move up and down, thereby changing the height between the eyepiece 1 and the objective lens 2 and the reading and writing platform, thereby changing the distance pulled away by the eyepiece 1. A guide mechanism extending in the up-down direction is provided between the installation box 31 and the articulated seat 34. The guide mechanism can be a protrusion or a groove on the side wall of the installation box 31 facing the articulated seat 34, and correspondingly, a groove or a protrusion is provided on the articulated seat 34 to provide guidance for the relative movement of the articulated seat 34 and the installation box 31.

[0036] When using most existing zooming scopes, it is necessary to manually open the eyepiece 1 and the objective lens 2 of the zooming scope. Since the damping of the hinge of some eyepieces 1 and objective lens 2 is relatively large when they leave the factory, the user needs to apply a large force, which is inconvenient to use. Alternatively, during the opening process, the hinge of the eyepiece 1 and the objective lens 2 may be damaged due to excessive force, and the objective lens 2 cannot be fixed to any position. Further, in order to solve this problem, a zooming scope of the present embodiment also includes a hinge sleeve 4 arranged between the eyepiece 1 and the objective lens 2.

[0037] Specifically, Figure 2 As shown, the top of the eyepiece 1 is an arc-shaped structure 11, and the articulated sleeve 4 is fixedly connected to the inner wall of the arc-shaped structure 11. Sealing covers 21 are provided on both sides of the top of the objective lens 2, and the two sealing covers 21 are movably connected to the two ends of the articulated sleeve 4. A rotating mechanism 5 is clamped in the articulated sleeve 4, and the two output ends of the rotating mechanism 5 are respectively fixedly connected to the corresponding sealing covers 21. The rotating mechanism 5 can drive the two sealing covers 21 to rotate around the axis of the articulated sleeve 4 to drive the objective lens 2 to rotate relative to the eyepiece 1. By arranging the rotating mechanism 5 in the articulated sleeve 4, the rotating mechanism 5 can drive the sealing covers 21 and the objective lens 2 to rotate, thereby realizing the automatic opening and closing of the objective lens 2, thereby preventing the hinge between the eyepiece 1 and the objective lens 2 from being damaged due to excessive force, thereby preventing the objective lens 2 from being unable to be fixed at any position. It should be noted here that the connection between the articulated sleeve 4 and the rotating mechanism 5 may be a groove-protrusion structure, that is, a groove or a protrusion may be provided on the inner wall of the articulated sleeve 4, and correspondingly, a protrusion or a groove matching the groove or the protrusion may be provided on the outer wall of the rotating mechanism 5 to position and connect the rotating mechanism 5, thereby ensuring that the rotating mechanism 5 does not move inside the articulated sleeve 4.

[0038] More specifically, if Figure 6 As shown, the rotating mechanism 5 includes a double-axis reduction motor 51 and two first transmission shafts 52. The double-axis reduction motor 51 is provided with a first groove or a first protrusion, and the inner wall of the articulated sleeve 4 is provided with a second protrusion or a second groove matched with the first groove or the first protrusion, so that the double-axis reduction motor 51 is clamped to the inside of the articulated sleeve 4 to prevent the double-axis reduction motor 51 from moving when driving the first transmission shaft 52 to rotate. The two output ends of the double-axis reduction motor 51 are respectively fixedly connected to one end of the corresponding first transmission shaft 52, and the other ends of the two first transmission shafts 52 are respectively fixedly connected to the corresponding sealing covers 21. Through the double-axis reduction motor 51, the two sealing covers 21 can be driven to rotate at the same time, thereby driving the objective lens 2 to rotate. By selecting the parameters of the double-axis reduction motor 51, the speed at which the objective lens 2 rotates relative to the eyepiece 1 can be controlled, thereby preventing the objective lens 2 from opening and closing too quickly and colliding with the eyepiece 1 to cause damage to the device.

[0039] Furthermore, if Figure 2As shown, the side wall of the arc structure 11 that can be attached to the objective lens 2 and the side wall of the bottom of the eyepiece 1 facing the objective lens 2 are both embedded with a limit switch 6. When the objective lens 2 is slowly opened to a position parallel to the reading and writing platform, the top of the side wall of the objective lens 2 away from the eyepiece 1 touches the limit switch 6 at the bottom of the arc structure 11, so that the double-axis reduction motor 51 stops immediately, thereby stopping the continued rotation of the objective lens 2; and when the telescope is no longer used, the double-axis reduction motor 51 drives the objective lens 2 to rotate in the direction of the eyepiece 1, and when the side wall of the objective lens 2 facing the eyepiece 1 touches the limit switch 6 set at the bottom of the eyepiece 1, the double-axis reduction motor 51 stops immediately, so that the objective lens 2 does not rotate anymore, and it is avoided that after the objective lens 2 is attached to the eyepiece 1, the double-axis reduction motor 51 is still driving the objective lens 2 to rotate, and when the objective lens 2 cannot continue to rotate, the double-axis reduction motor 51 will be blocked and the device will be avoided from being damaged.

[0040] Furthermore, if Figure 1 and Figure 2 As shown, when using the zoom mirror, there may be too much sunlight during the day, or the brightness of the lights in the room at night is too bright, which may cause the image displayed by the eyepiece 1 to have a large light spot. In order to solve this problem, a zoom mirror of this embodiment also includes two light shields 7. The two light shields 7 are detachably mounted on the side walls corresponding to the hinged ends of the eyepiece 1 and the objective lens 2, respectively, and the two light shields 7 can be folded or unfolded to form an observation space between the eyepiece 1, the objective lens 2 and the two light shields 7, so that the image reflected by the objective lens 2 and the eyepiece 1 reduces the formation of light spots, making the image reflected by the eyepiece 1 clearer. Preferably, a fill light is provided at the bottom of the eyepiece 1 to prevent the image reflected by the eyepiece 1 from being unclear due to insufficient light when the observation space is too dark.

[0041] Specifically, the light shield 7 includes two mounting plates 71 and a light shielding cloth 72. The two mounting plates 71 are detachably mounted on the side walls on the same side of the eyepiece 1 and the objective lens 2, respectively, and the light shielding cloth 72 is connected between the two mounting plates 71 in a foldable or unfoldable manner, so that an observation space is formed between the objective lens 2, the eyepiece 1 and the two light shielding cloths 72. The outer edge of the light shielding cloth 72 is arc-shaped, similar to the form of a fan, so that when the light shielding cloth 72 is unfolded between the two mounting plates 71, it can be more beautiful, more convenient to use, and more portable when stored. It should be noted that the clamping of the two mounting plates 71 can be an insert-type clamping form, a hook-type clamping form, or other clamping structures. This is a prior art and will not be described in detail.

[0042] Furthermore, if Figure 1-Figure 2 and Figure 7 As shown, the telescope further comprises folding legs 8 and a stacking seat 9.

[0043] Specifically, the top of the folding leg 8 is hinged to the hinge seat 34, the folding leg 8 includes a plurality of legs 81 and the plurality of legs 81 are hinged in sequence, and every two legs 81 are connected by a first screw 82 and a first nut 83, one end of the first screw 82 passes through two adjacent legs 81 and the first nut 83 in sequence, wherein the first nut 83 is embedded in one side wall of the leg 81, and the other end of the first screw 82 is fixedly installed with a first knob 84. A stacking space 91 is provided at the top of the stacking seat 9, and a mounting block 92 is fixedly installed on the bottom wall of the stacking space 91, and a protrusion is provided at the top of the mounting block 92, which can limit the rotatable angle of the bottommost leg 81, so that the plurality of legs 81 have only two positions, namely, the storage position and the use position. When the plurality of legs 81 are in the use position, the two ends of the leg 81 at the bottom fit with the two side walls of the mounting block 92, and the two are connected by a second screw 93 and a second nut 94. In addition, the protrusion on the mounting block 92 blocks the rotation of the leg 81 at the bottom, thereby limiting the rotation angle of the leg 81, so that the leg 81 can be fixed at an angle when in use, that is, located at the use position. Among them, the second nut 94 is embedded in the side wall of the mounting block 92, one end of the second screw rod 93 passes through the stacking seat 9, the mounting block 92, the leg 81 at the bottom and the second nut 94 in sequence, and the other end of the second screw rod 93 is fixedly mounted with a second knob 95. By providing multiple legs 81 and the stacking seat 9, the relative rotation of the eyepiece 1 and the objective lens 2 through the multiple legs 81 can be achieved, that is, the multiple legs 81 are relatively folded, and the objective lens 2 and the eyepiece 1 are folded and stored in the stacking space 91 of the stacking seat 9, thereby reducing the storage space occupied by the telescope when not in use.

[0044] Except for the topmost leg 81, the rest of the legs 81 are provided with a limiting plate 85 in the middle to limit the rotatable angle of the adjacent upper leg 81. Preferably, a groove structure is provided on the top of the stacking seat 9 and on both sides of the stacking space 91 to facilitate taking out the zoom lens.

[0045] The working process of a telescope in this embodiment is as follows:

[0046] like Figure 1-Figure 2 , Figure 5-Figure 7As shown, the device is first assembled, and then in the non-use state, that is, in the initial state, the telescope is stacked in the stacking space 91 of the stacking seat 9, and the telescope is taken out from the stacking space 91 through the two groove structures, and the postures of the eyepiece 1 and the objective lens 2 are fixed by multiple legs 81. Then, the double-axis reduction motor 51 is driven to rotate by a remote controller or other equipment, so that the objective lens 2 is slowly opened. When the objective lens 2 touches the limit switch 6 embedded in the arc structure 11, the objective lens 2 stops rotating. Alternatively, during the rotation of the objective lens 2, the rotation of the double-axis reduction motor 51 can also be stopped by the remote controller, so that the objective lens 2 stops at a certain position. Generally, when the objective lens 2 is opened, it stops at a position parallel to the reading and writing platform. Then, according to actual needs, the height of the eyepiece 1 and the objective lens 2 from the reading and writing platform is adjusted. The remote controller transmits a signal to the single-axis reduction motor 35 to drive the single-axis reduction motor 35 to rotate the driving gear, thereby driving the driven gear to rotate, and the two racks 32 move in the same direction to adjust the height of the eyepiece 1 and the objective lens 2.

[0047] Embodiment 2

[0048] Different from the first embodiment, Figure 3 and Figure 4 As shown, the rotating mechanism 5 in this embodiment includes a dual-axis motor 53, a second transmission shaft 54 ​​connected to the two output ends of the dual-axis motor 53 in sequence, a planetary gear set 55 and a third transmission shaft 56, and the ends of the two third transmission shafts 56 away from the planetary gear set 55 are fixedly connected to the corresponding sealing covers 21 respectively.

[0049] Specifically, the planetary gear set 55 includes a ring gear 551, a sun gear 552 and a plurality of planetary gears 553. The ring gear 551 is a cylindrical structure, and the outer walls of the ring gear 551 and the dual-axis motor 53 are both provided with a third groove or a third protrusion, and the inner wall of the articulated sleeve 4 is provided with a fourth protrusion or a fourth groove that matches the third groove or the third protrusion, so as to clamp the ring gear 551 and the dual-axis motor 53 inside the articulated sleeve 4, thereby restricting the ring gear 551 and the dual-axis motor 53 from rotating relative to the articulated sleeve 4. The sun gear 552 is located in the ring gear 551, and the sun gear 552 is coaxially arranged with the ring gear 551. A plurality of planetary gears 553 are located between the ring gear 551 and the sun gear 552, and are evenly arranged along the circumference of the ring gear 551 and the sun gear 552, and the plurality of planetary gears 553 are all meshed with the ring gear 551 and the sun gear 552. One end of the second transmission shaft 54 ​​away from the dual-axis motor 53 passes through the gear ring 551 and is fixedly connected to the sun gear 552. One end of the third transmission shaft 56 away from the sealing cover 21 is connected to the multiple planetary gears 553 one by one through multiple mounting rods. The output end of the dual-axis motor 53, the second transmission shaft 54, the sun gear 552 and the third transmission shaft 56 are coaxially arranged. The dual-axis motor 53 drives the second transmission shaft 54 ​​to rotate, so as to drive the sun gear 552 to rotate, thereby realizing the circumferential movement of the multiple planetary gears 553 around the axis of the sun gear 552, thereby driving the third transmission shaft 56 to rotate, so as to realize the rotation of the objective lens 2, and realize the slow rotation of the objective lens 2.
