Description

Technical Field

[0001] The utility model relates to the technical field of myopia protection equipment, in particular to a flip racket. Background Art

[0002] At present, the myopia rate among Chinese teenagers remains high, which has attracted great attention from relevant departments such as the Ministry of Education and the Ministry of Health. In addition to the existing means of fitting glasses, laser surgery, corneal reshaping and other technologies, visual function training has become a safe, effective and convenient method for preventing and controlling myopia. Among them, the flip camera is the most common and effective instrument.

[0003] The flipping racket, also known as the reverse racket or butterfly racket, is an eye care tool composed of two pairs of positive and negative spherical lenses of equal power. Its working principle is to change the accommodative stimulation, the positive lens reduces the accommodative stimulation, the negative lens increases the accommodative stimulation, and the convergent stimulation remains unchanged, so the change of accommodative convergence is accompanied by a change of fusional convergence of the same magnitude but opposite direction, that is, by using lenses of opposite power, i.e. myopia lenses and hyperopia lenses, alternately using positive and reverse lenses to observe things, it can prevent myopia and protect the eyes.

[0004] When the flip-up racket currently on the market needs to replace different lenses, the lenses are usually directly snapped off the frames and replaced with new lenses. This is time-consuming, labor-intensive and very inconvenient. Another type of flip-up racket has a frame that slides on a rod to adjust the pupil distance. The sliding and limiting are achieved through a gear transmission structure. The structure is complex and the practicality is poor. Utility Model Content

[0005] The utility model aims to provide a flip racket designed to solve the deficiencies of the above-mentioned technology.

[0006] The utility model discloses a flip-up racket, comprising a mirror rod and two mirror frames, each of the mirror frames comprising a sliding portion slidably connected to the mirror rod, the sliding portion being radially distributed with at least one lens with the axial direction of the mirror rod as the center point, the lenses of the two mirror frames on the same side being a group of lenses with the same degree, a buckle portion being provided between the sliding portion of one of the mirror frames and the mirror rod, the mirror frame being limited to the mirror rod by the buckle portion, and the other frame being reciprocatingly slidable relative to the frame along the mirror rod, so that the distance between the lenses of the two frames can be adjusted.

[0007] Preferably, the sliding portion is provided with an axial through hole, and the mirror rod is inserted into the axial through hole.

[0008] According to further optimization, when the mirror rod is inserted into the axial through hole, the sliding part forms a radial limit relative to the mirror rod to prevent the sliding part and the mirror rod from rotating relative to each other in the radial direction.

[0009] According to further optimization, damping sliding is formed between the axial through hole of the sliding portion and the mirror rod.

[0010] Further optimized, the buckle portion includes a tongue which is arranged on the mirror rod and has elastic deformation, and the sliding portion is provided with a groove which communicates with the axial through hole and forms a buckle fit with the tongue.

[0011] Further optimized, the frame is snapped onto the top of the mirror pole.

[0012] Further optimized, the latch tongue includes an elastic latch strip and a protrusion, the elastic latch strip extends out from the latch slot, and the protrusion is located on the elastic latch strip and is integral with the elastic latch strip.

[0013] Further optimization is that a handle is provided at the bottom of the mirror rod.

[0014] Further optimization, the handle is a rotating body that is easy to rotate manually, and the rotating body is a cylinder.

[0015] Preferably, the mirror rod shaft is provided with an axial scale.

[0016] The technical effect of the utility model is that two frames are sleeved on the mirror rod, one of the frames can slide along the mirror rod, and the other frame is clamped on the mirror rod by a buckle part, so that the distance of one frame relative to the other frame can be adjusted, that is, the pupil distance can be adjusted, and at the same time the two frames can be detached, which is convenient for replacing lenses of different degrees. Therefore, not only is the structure simple and easy to implement, but also the lenses are convenient to load and unload; the grip part of the mirror rod is a rotating body, which is convenient for hand-held rotation of the mirror rod and easy flipping and shooting.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model belong to the scope of protection of the present utility model.

[0025] In this embodiment, as Figure 1 and 2 shown, it includes a lens rod 1 and two lens frames 2. Each lens frame 2 includes a sliding part 21 and a lens 23. The sliding part 21 is slidably connected to the lens rod 1. Specifically, an axial through hole 22 is formed in the center of the sliding part 21, and the lens rod 1 passes through the axial through hole 22, so that the sliding part 21 can reciprocally slide along the axial direction of the lens rod 1. At least one lens 23 is radially distributed on the sliding part 21 with the axial direction of the lens rod 1 as the center point, that is, the lens 23 is radially distributed on each sliding part 21. The lens 23 and the lens rod 1 are in the same horizontal plane. In this embodiment, the number of lenses 23 is two, symmetrically distributed on both sides of the sliding part 21. The lens 23 is fixedly connected to the sliding part 21 through a frame. The frame and the sliding part 21 are integrally designed. Of course, the frame can also be detachably connected to the sliding part 21. The lens 23 slides together with the frame and the sliding part 21, and is loaded and unloaded together with the frame and the sliding part 21. The lens 23 in this embodiment cannot be separated and disassembled from the sliding part 21.

[0026] The two lens frames 2 are sleeved on the lens rod 1 along the axial direction of the lens rod 1 through their respective sliding parts 21. The lenses 23 on the same side of the two lens frames 2 are a group of lenses 23 with the same degree. A buckle part is provided between the sliding part 21 of one lens frame 2 and the lens rod 1. This lens frame 2 is limited to the lens rod 1 through the buckle part, and the other lens frame 2 reciprocally slides along the lens rod 1 relative to this lens frame 2 for adjusting the interpupillary distance.

[0027] In this embodiment, the lens rod 1 is a square rod, and the axial through hole 22 of the sliding part 21 is a square hole, so that a radial limit is formed after the lens rod 1 is inserted into the axial through hole 22 of the sliding part 21, preventing relative radial rotation between the sliding part 21 and the lens rod 1. When the lens rod 1 is placed horizontally, the eyes are aligned with a group of lenses 23, and then by rotating the lens rod 1, different groups of lenses 23, that is, lenses 23 with different degrees, can be sequentially switched to be aligned with the eyes to realize the function of the flip lens.

[0028] It should be noted that the fit between the axial through hole 22 of the sliding part 21 and the lens rod 1 is a static friction sliding. By changing the surface roughness of the inner wall of the axial through hole 22 or the surface of the lens rod 1, or changing the fit size between the two, a damping sliding is formed, so that the sliding part 21 can slide precisely and slowly, facilitating the adjustment of the interpupillary distance.

[0029] One of the spectacle frames 2 is clamped on the spectacle rod 1 through a clamping part, so that the spectacle frame 2 is sleeved on the spectacle rod 1 and remains fixed relative to the spectacle rod 1. The clamping part includes a tongue 3 arranged on the rod body of the spectacle rod 1 and having elastic deformation. A clamping groove 4 communicating with the axial through hole 22 is arranged on the sliding part 21. When the sliding part 21 of the spectacle frame 2 is sleeved on the spectacle rod 1, the tongue 3 is clamped into the clamping groove 4 to form a clamping fit, thereby fixing the spectacle frame 2.

[0030] Furthermore, the tongue 3 is arranged at the top of the spectacle rod 1, and the clamping groove 4 is arranged on the outer periphery of one end of the sliding part 21 and penetrates through the end face of this end, so that the spectacle frame 2 is fixed at the top end of the spectacle rod 1, increasing the sliding distance of the other slidable spectacle frame 2. Generally, the space utilization rate of the spectacle rod 1 is higher.

[0031] Furthermore, the tongue 3 includes an elastic strip 31 and a protrusion 32. The elastic strip 31 extends out from the clamping groove 4. The protrusion 32 is located on the elastic strip 31 and is integral with the elastic strip 31. The protrusion 32 extends out from the elastic strip 31 and the protrusion 32 protrudes above the clamping groove 4. When the sliding part 21 slides to the position where the strip is located, the inner wall of the axial through hole 22 of the sliding part 21 presses the protrusion 32, so that the protrusion 32 retracts into the clamping groove 4 under the action of the elastic strip 31. When the sliding part 21 continues to slide until the clamping groove 4 is aligned with the protrusion 32, the protrusion 32 rebounds under the action of the elastic strip 31 and extends into the clamping groove 4, and is buckled with the inner side wall of the clamping groove 4 to form an axial limit.

[0032] It should be noted that when the tongue 3 is arranged at the top of the spectacle rod 1, that is, when the spectacle frame 2 is buckled at the top end of the spectacle rod 1, a limiting protrusion 24 is arranged at the corresponding end of the sliding part 21. The limiting protrusion 24 extends out from the inner wall of the sliding part 21 or the axial through hole 22. When the sliding part 21 is sleeved on the top end of the spectacle rod 1, the limiting protrusion 24 forms an axial limit on the top end of the spectacle rod 1 to prevent the spectacle rod 1 from continuing to pass through the axial through hole 22. That is to say, the protrusion 32 and the limiting protrusion 24 respectively limit the sliding part 21 in the opposite axial directions, so that the spectacle frame 2 is fixed at the top end of the spectacle rod 1 to prevent it from sliding along the axis of the spectacle rod 1.

[0033] A handle 5 is arranged at the bottom end of the spectacle rod 1. The handle 5 is a rotating body convenient for manual rotation, such as a cylindrical body or a frustum of a cone, etc., which is convenient for holding and rotating the spectacle rod 1.

[0034] Axial scales 6 are arranged on the rod body of the spectacle rod 1, which is convenient for accurately adjusting the relative distance between the two spectacle frames 2.

[0035] The utility model is not limited to the above best implementation mode. Anyone can obtain other various forms of products under the inspiration of the utility model. However, no matter what changes are made in its shape or structure, as long as it has a technical solution identical or similar to the present application, it falls within the protection scope of the utility model.
