Description

Technical Field

[0001] The utility model relates to the technical field of vision training instruments, in particular to an electric flip racket. Background Art

[0002] The vision adjustment training is carried out using a vision training flipping racket, which is a hand-held flipping racket that is manually flipped back and forth to carry out vision adjustment training.

[0003] The flipping mirror is an examination device for the clinical examination of accommodation / convergence flexibility in optometry, and is also a training device for improving flexibility. When using it, the flipping mirror is flipped after seeing the words on the near vision chart at a certain distance. The patient uses lenses with the same positive and negative lens powers, and flips the two-sided mirror in front of his eyes after seeing the sight mark on the vision card clearly. Flipping the positive mirror once and the negative mirror once is one cycle, and the number of flipping cycles in 1 minute needs to be recorded during the test. Usually, doctors not only need to record the time, but also need to judge whether each sight mark is really seen accurately and record the final number of flips, which usually increases the workload of the examiner. The examinee's mastery of the flipping action often goes from unfamiliar to proficient, which may increase the measurement error caused by the unfamiliar flipping action during the first examination. There is often a single eye measurement during the accommodation examination, and the trial frame is usually blocked with a black film, but it is very inconvenient for the examinee who does not wear glasses to train at home.

[0036] Since the driving mechanism 2 can drive the mirror frame 31 to rotate along its axis to drive the two positive mirrors 32 and the two negative mirrors 33 thereon to rotate forward or reversely, so that the two positive mirrors 32 or the two negative mirrors 33 are alternately located in the two through holes 11, the positive mirrors 32 and the negative mirrors 33 are automatically flipped, thereby avoiding detection errors. At the same time, since at least one opening 12 for installing and removing the positive mirror 32 or the negative mirror 33 is provided on the side wall of the housing 1, it is convenient to replace the built-in lens. In addition, the electric flip racket also includes a shielding member 4, which can quickly shield the other eye during a single-eye test.

[0040] like Figure 3 and Figure 4As shown, the frame 31 includes a cross 311 and four mounting frames 312, one side of the center of the cross 311 is connected to the driving mechanism 2, the other side of the cross 311 is rotatably connected to the housing 1, the four mounting frames 312 are respectively connected to the four ends of the cross 311, the mounting frame 312 is a semicircular structure, the positive mirror 32 and the negative mirror 33 are respectively engaged with the four mounting frames 312, and the positive mirror 32 and the negative mirror 33 are alternately arranged. In the process of actual application, each rod body of the cross 311 can be a telescopic rod to adapt to different pupil distances of different patients, wherein the telescopic rod can be set to 6 gears, so that the center distance between the two lenses can be switched between 54mm, 56mm, 58mm, 60mm, 62mm, and 64mm.

[0041] like Figure 2-Figure 4 As shown, the driving mechanism 2 includes a driving member 21 and a transmission assembly 22 . The driving member 21 drives the cross 311 to rotate along its central axis through the transmission assembly 22 . The transmission assembly 22 includes an active bevel gear 221, a passive bevel gear 222, a first gear 223, a second gear 224, a third gear 225 and a fourth gear 226. The driving end of the driving member 21 is connected to the active bevel gear 221, the active bevel gear 221 is meshed with the passive bevel gear 222, the passive bevel gear 222 is connected to the first gear 223 through a connecting shaft, the first gear 223 is meshed with the second gear 224, the second gear 224 is meshed with the third gear 225, the third gear 225 is meshed with the fourth gear 226, and the center of the fourth gear 226 is fixedly connected to the center of the cross 311, and then when the active bevel gear 221 rotates, the cross 311 is driven to rotate along its center through the meshing of each gear. It should be noted that in the actual installation process of the gear, a central axis is provided at the center of the gear, and the two ends of the central axis are overlapped with the opposite side walls inside the housing 1 respectively to ensure the stable installation of the gear. The installation process of the gear will not be repeated here, and the installation process of the gear in the prior art can be adopted.
