Description

Technical Field

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

[0002] The pathogenesis of myopia is complex, and internationally recognized factors include two main categories: genetics and environment. Genetic factors, such as exophoria (exotropic strabismus), are inherent to myopia and cannot be changed. Regarding environmental factors, the main factors internationally recognized as contributing to the progression of myopia are: 1) Excessive close-up work and insufficient time spent looking at distant objects, leading to eye strain. 2) Ambient lighting, etc. Currently, the distance between the reader and the book is relatively close, and prolonged close-up reading easily leads to myopia. Using a telescope can increase the time spent looking at distant objects and quickly relieve eye strain.

[0003] A telescope works by using two continuously rotating prism lenses to cause the lateral rectus muscle to contract when the eye is looking at near objects. This generates a counterforce, relieving the tension in the ciliary muscle. Reading a book, using a computer, or watching TV for 15 minutes is equivalent to looking at distant objects for 3 hours, thus eliminating eye strain and preventing myopia. Specifically, the telescope quickly relaxes the eyes through rotation, reducing the need for convergence and accommodation, thereby relieving ciliary muscle fatigue in a short time, promoting the reverse growth of the eyeball, and improving ocular microcirculation.

[0004] However, since the interpupillary distance varies among different ages and users, existing telescopes are not convenient to adjust their size according to the user's interpupillary distance, and cannot effectively relieve fatigue. Furthermore, different users require different prism lenses, and existing telescopes are not convenient to quickly replace prism lenses, making them inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that it is inconvenient to adjust the size and replace the prism composite lens according to different users, and to propose a powerful telescope for the eyes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A powerful telescope for the eye includes a retractable housing and a transmission assembly for actuating the retraction of the housing. The housing includes a connecting shell and two mounting shells that slide on the outer surface of the connecting shell.

[0008] The two mounting shells are respectively provided with two sets of clamping components for fixing the prism lens. The top of the mounting shell is provided with a limiting groove for installing the clamping components. The clamping components are provided with limiting components for limiting the clamping components.

[0009] In some embodiments, the housing further includes an elastic band fixed between two mounting shells, both the connecting shell and the elastic band being L-shaped, and the surfaces of the two mounting shells are respectively provided with telescopic holes for mounting the prism lens.

[0010] In some embodiments, the clamping assembly includes two symmetrically arranged clamping blocks, one of which has a plurality of first positioning pins fixed on its opposite surface, and the other clamping block has a plurality of first positioning holes on its opposite surface, wherein the plurality of first positioning pins and the plurality of first positioning holes cooperate with each other.

[0011] In some embodiments, grooves for rotating the prism composite lens are provided on the corresponding surfaces of the two clamping blocks, and stepped grooves for allowing the prism composite lens to protrude are provided on the side of the two clamping blocks near the connecting shell, and the upper ends of the two clamping blocks cooperate with the limiting grooves.

[0012] In some embodiments, a plurality of second positioning pins are fixed to the bottom of the mounting housing, and two second positioning holes are respectively opened on the lower surface of the two clamping blocks, with the plurality of second positioning pins corresponding to the positions of the plurality of second positioning holes.

[0013] In some embodiments, the limiting component is disposed on the top of one of the clamping blocks. The limiting component includes a cavity formed inside one of the clamping blocks and a locking block that slides laterally inside the cavity. A spring is provided inside the cavity for driving the locking block to slide towards the connecting shell side. A locking groove that cooperates with the locking block is formed on the side of the limiting groove.

[0014] Compared with the prior art, the present invention provides a powerful telescope for the eye, which has the following beneficial effects.

[0015] 1. This utility model uses a transmission component to drive two mounting shells and sliders to slide on the surface of a guide rod, thereby bringing the two telescope holes closer to or further apart from each other, adjusting the distance between the two mounting shells and the two sets of prism composite lenses to accommodate the interpupillary distance of different users.

[0016] 2. In this utility model, by setting a clamping component, the two clamping blocks are separated, the prism composite lens located between the two clamping blocks is taken out, and a suitable prism composite lens is replaced. Under the action of multiple first positioning pins and first positioning holes, the two clamping blocks are positioned and merged, and the prism composite lens is limited. Under the action of the limiting component, the clamping component is limited.

[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figure 1-9A powerful telescope for eyes includes a retractable housing 1 and a transmission assembly 2 for driving the housing 1 to extend and retract. The housing 1 includes a connecting housing 101 and two mounting housings 102 that slide on the outer surface of the connecting housing 101. The connecting housing 101 is L-shaped. An elastic band 103 is fixed between the two mounting housings 102. The elastic band 103 is L-shaped and its two ends are in contact with the two ends of the connecting housing 101. The surfaces of the two mounting housings 102 are respectively provided with telescope holes 104 for mounting a prism-transparent composite lens 5. A guide rod 105 is fixed to the top inside the connecting housing 101. Slider blocks 106 are respectively fixed to the top inside the two mounting housings 102. The two mounting housings 102 slide on the two ends of the guide rod 105 through the two sliders 106. The guide rod 105 is located near the corner of the connecting housing 101.

[0031] The transmission assembly 2 includes a positive and negative threaded post 201 that rotates on the top of the connecting shell 101. The positive and negative threaded post 201 is located at the rear end of the connecting shell 101. Movable blocks 202 are fixed on the top of the two mounting shells 102 respectively. The two movable blocks 202 are threadedly connected to the surface of the positive and negative threaded post 201. A worm gear 203 is fixedly assembled in the middle of the positive and negative threaded post 201. A worm 204 rotates on the surface of the connecting shell 101. The worm 204 meshes with the worm gear 203. A handle is fixed at the upper end of the worm 204.

[0032] It is understandable that the worm gear 204 is rotated by the handle, and with the cooperation of the worm gear 204 and the worm wheel 203, the positive and negative threaded columns 201 are rotated. This causes the two moving blocks 202 to drive the two mounting shells 102 to slide on the surface of the guide rod 105 via the slider 106. This allows the two telescope holes 104 to move closer or further apart, adjusting the distance between the two mounting shells 102 and the two sets of prism composite lenses 5 to accommodate different users' interpupillary distances. The elastic band 103 is provided to improve the user's comfort when wearing the lens, and the size of the elastic band 103 can be adjusted according to the movement of the two mounting shells 102.

[0033] Specifically, the telescope aperture 104 has a discontinuous section in the middle. The top of the mounting housing 102 is provided with a limiting groove 3 for installing the clamping assembly 4. The clamping assembly 4 is used to fix the prism composite lens 5. The clamping assembly 4 includes two symmetrically arranged clamping blocks 401. One clamping block 401 has multiple first positioning pins 402 fixed on its opposite surface. The other clamping block 401 has multiple first positioning holes 403 on its opposite surface. The multiple first positioning pins 402 and the multiple first positioning holes 403 cooperate with each other. The corresponding surfaces of the two clamping blocks 401 have grooves for rotating the prism composite lens 5. The side of the two clamping blocks 401 near the connecting housing 101 has a stepped groove for allowing the prism composite lens 5 to protrude. The upper ends of the two clamping blocks 401 cooperate with the limiting groove 3. Pull plates are fixed on the upper surfaces of the two clamping blocks 401. When the clamping assembly 4 drives the prism composite lens 5 to be inserted into the mounting housing 102 through the limiting groove 3, the position of the prism composite lens 5 corresponds to that of the telescope aperture 104.

[0034] Understandably, by pulling out the two clamping blocks 401 and the prism composite mirror 5 simultaneously from the mounting housing 102 using two pull plates, the two clamping blocks 401 are separated, the prism composite mirror 5 located between the two clamping blocks 401 is removed, a suitable prism composite mirror 5 is replaced, and then the two clamping blocks 401 are positioned and merged through multiple first positioning pins 402 and first positioning holes 403, and the two clamping blocks 401 are inserted into the mounting housing 102, thereby achieving the purpose of quickly replacing the prism composite mirror 5.

[0035] Specifically, the bottom of the mounting housing 102 is fixed with multiple second positioning pins 6, all of which are stepped. The lower surfaces of the two clamping blocks 401 are respectively provided with two second positioning holes 7, and the multiple second positioning pins 6 correspond to the positions of the multiple second positioning holes 7.

[0036] It is understandable that by setting the second positioning pin 6 and the second positioning hole 7, after the clamping block 401 is inserted into the mounting shell 102, it is inserted into the surface of the second positioning pin 6 through the second positioning hole 7, thereby limiting the position of the bottom of the two clamping blocks 401 and preventing the two clamping blocks 401 from separating and causing the prism composite mirror 5 to loosen.

[0037] Specifically, one of the clamping blocks 401 is provided with a limiting component 8 at its top for limiting the clamping assembly 4. The limiting component 8 includes a cavity 801 opened inside one of the clamping blocks 401 and a locking block 802 that slides laterally inside the cavity 801. The locking block 802 extends out of the clamping block 401 at one end near the connecting shell 101. A spring 803 is provided inside the cavity 801 for driving the locking block 802 to slide towards the connecting shell 101. The upper end of the locking block 802 extends out of the upper surface of the clamping block 401. A locking groove 804 that cooperates with the locking block 802 is opened on the side of the limiting groove 3.

[0038] It is understandable that after the two clamping blocks 401 are inserted into the mounting shell 102, the spring 803 pushes the card block 802 into the card slot 804. With the cooperation of the card block 802 and the card slot 804, the clamping component 4 is limited to prevent it from falling out of the mounting shell 102 at will.

[0039] Specifically, each of the two mounting housings 102 is equipped with a coaxial reversing assembly 9 for driving the two prism composite mirrors 5 to rotate in opposite directions. The coaxial reversing assembly includes two transmission wheels 902 that rotate through a connecting shaft 901. The two transmission wheels 902 are respectively engaged with the two prism composite mirrors 5. The other end of one connecting shaft 901 is fixed to the inner wall of the mounting housing 102, and the other end of the other connecting shaft 901 is fixed to one end of the output shaft of the motor. The motor is fixed to the inner wall of the mounting housing 102. The opposite ends of the two transmission wheels 902 are respectively fixed with a first bevel gear 903. The bottom of the mounting housing 102 is fixed with a second bevel gear 903. The second bevel gear 903 meshes with the two first bevel gears 903 respectively.

[0040] Understandably, by driving one of the transmission wheels 902 to rotate through the motor, and through the meshing relationship of the two first bevel gears 903 and the second bevel gear 903, the other transmission wheel 902 rotates in the opposite direction, causing the two transmission wheels 902 to drive the two prism composite mirrors 5 to rotate in opposite directions simultaneously. The user looks at the prism composite mirror 5 through the telescope 104, thereby quickly relieving eye fatigue.

[0041] Specifically, each of the two mounting shells 102 has a strap 10 fixed to its rear, and each strap 10 has a Velcro strap 11 on its surface. Each of the two mounting shells 102 has a sponge pad 12 fixed to its rear.

[0042] Understandably, by setting up the restraint strap 10 and Velcro 11, it is easy to wear the telescope on the head, and the comfort of wearing it can be improved with the help of the two sponge pads 12.

[0043] In this invention, when the prism composite lens 5 needs to be replaced, the locking block 802 is moved to separate it from the slot 804. Two pull plates then pull the two clamping blocks 401 and the prism composite lens 5 out of the mounting housing 102 simultaneously, separating the two clamping blocks 401. The prism composite lens 5 located between the two clamping blocks 401 is removed and replaced with a suitable one. The two clamping blocks 401 are then positioned and merged using multiple first positioning pins 402 and first positioning holes 403. The two clamping blocks 401 are then inserted into the mounting housing 102. Under the action of the second positioning pin 6 and the second positioning hole 7, the bottom positions of the two clamping blocks 401 are limited to prevent the prism composite lens 5 from loosening due to separation. Simultaneously, the spring 803 pushes the locking block 802 into the slot 804. With the cooperation of 802 and slot 804, the clamping component 4 is limited. The telescope is worn on the head by the strap 10 and Velcro 11. The worm gear 204 is rotated by the handle. With the cooperation of the worm gear 204 and worm wheel 203, the positive and negative threaded column 201 is rotated, so that the two telescope holes 104 are brought closer or further apart. The distance between the two mounting shells 102 and the two sets of prism composite lenses 5 is adjusted according to the user's interpupillary distance. Then, the motor drives one of the transmission wheels 902 to rotate. With the meshing relationship of the two first bevel gears 903 and the second bevel gear 903, the other transmission wheel 902 rotates in the opposite direction. The two transmission wheels 902 drive the two prism composite lenses 5 to rotate in opposite directions at the same time. The user looks at the prism composite lens 5 through the telescope hole 104, thereby quickly relieving eye fatigue.
