The purpose of this utility model will overcome above-mentioned defective exactly, provides a kind of simple in structure, can use close-in target mock inspection distant object, and the eye ciliary muscle is regulated level and smooth moderate hypermetropia myopia comprehensive physiotherapy appearance.

For realizing this purpose, a kind of hypermetropia myopia comprehensive physiotherapy appearance that this utility model is designed includes an observation framework that seals, and an end of observing framework is provided with a zoom lens barrel, and design has at least one group of ultra-short focus and zooming combined lens in the zoom lens barrel; The other end of observing framework is provided with one and observes image, and the distance H design between the front end observation port of observation image and zoom lens barrel is in 250 millimeters; Observe in the framework permanent magnetic step motor also is installed, and the control circuit board that drives the automatic positive and negative running of permanent magnetic step motor, the output shaft of permanent magnetic step motor and a combination drive mechanism link, and are changed by the position reciprocation cycle between this combination transmission mechanism control ultra-short focus and zooming combined lens and the observation image.Its operation principle is in the near-ambient of a sealing, utilization ultra-short focus and zooming combined lens and the orientation of observing between the image come and go continuously mobile, make observed scenery in 250 millimeters scopes of the bright adjacency distance of human eye, the people who produces twenty-twenty vision can continuous clear identification in natural environment virtual image, such as mock inspection to image scaled and the zoom visual effect people that is equivalent to twenty-twenty vision can clear identification in the scope of 250 millimeters to 1 meter of natural environment image scaled and zoom visual effect.Simultaneously, according to the near-sighted presbyopic actual state of difference, can be far regulate coming and going far away clear adjacent boundary point and the nearly clear adjacent boundary point that circulation physical therapy observation post needs automatically, make far away fuzzy a bit (time of staying be about a second) of viewed virtual image after just surpassing clear adjacent boundary point far away and firm above the paste of the near-lying mode behind nearly clear adjacent boundary's point circulation change repeatedly between (time of staying is about a second) a bit with control circuit board.

Advantage of the present utility model is: designed physiotherapy table is the far and near variation of ultrashort burnt simulates real outdoor scene thing in the sealing near-ambient, make scenery produce the virtual image that twenty-twenty vision can clear identification in human eye can not 250 millimeters scopes of the distance of distinct vision of clear recognition image, its compact conformation, volume be small and exquisite, in light weight, it is very convenient to portably use.What is more important: human eye is being done to a bit fuzzy and fuzzy from far near any continuous variation far away clocklike in the observation process repeatedly by near virtual image, ciliary muscle has obtained continuously smooth contraction clocklike and has loosened adjusting, this stretched and relaxed practicing repeatedly, the balance that makes the regulating power of eyes ciliary muscle obtain unified coordination is taken exercise.And can make the contraction of ciliary muscle or loosen adjusting far and near limit range after being in regulating power all the time and progressively being recovered by control circuit; thereby regulatory function active and the enhancing eye; add soaking by easy stages; to the contraction of ciliary muscle or loosen and regulate the recovery of doing protectiveness and take exercise; and then eliminate visual fatigue, improve an eye body function, satisfy the needs of near, distant vision treatment and twenty-twenty vision health care.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Fig. 1 is a kind of structural representation of hypermetropia myopia comprehensive physiotherapy appearance;

Fig. 2 is the structural representation of another kind of hypermetropia myopia comprehensive physiotherapy appearance;

As shown in Figure 1 hypermetropia myopia comprehensive physiotherapy appearance has the observation framework 7 of an enclosed construction, and the bottom left end of observing framework 7 is equipped with a zoom lens barrel 3, and design has at least one group of ultra-short focus and zooming combined lens 4 in the zoom lens barrel 3.The bottom right-hand member of observing framework 7 is equipped with one and observes image 5, and the distance design between the left side observation port of observation image 5 and zoom lens barrel 3 is in 250 millimeters.The control circuit board 6 of permanent magnetic step motor 1 and the 1 automatic positive and negative running of driving permanent magnetic step motor is installed on the upper bracket of observation framework 7.The output shaft of permanent magnetic step motor 1 is connected with a machinery

combination drive mechanism

2, and 2 of machinery combination drive mechanisms directly link with the interior ultra-short focus and zooming combined lens 4 of zoom lens barrel 3.The associated datas such as just commentaries on classics, counter-rotating and rotating speed that need during in advance with permanent magnetic step motor 1 work are input in the control circuit board 6, and this is easy to finish for the professional and technical personnel.During physiotherapy table work, after permanent magnetic step motor 1 is received the just commentaries on classics drive pulse signal that control circuit board 6 sends, the clockwise direction rotation drives machinery combination drive mechanism 2 motions that are contained on its output shaft, drive ultra-short focus and zooming combined lens 4 towards the stroke distances of observing image 5 direction displacement defineds by mechanism's combination drive mechanism 2 again, finish observing the stretching and the autozoom of image 5, it is clear that viewed emulating image is remained in change procedure from far near.After permanent magnetic step motor 1 is received the counter-rotating driving pulse that control circuit board 6 sends, rotation counterclockwise drives machinery combination drive mechanism 2 adverse movements that are contained on its output shaft, drive the stroke distances of ultra-short focus and zooming combined lens 4 to the opposite direction displacement defined of observing image 5, viewed emulating image ratio is produced by near carry out autozoom to variation far away and to it, thereby finish one from far near, by nearly extremely reciprocating motion process far away, so periodic cycle is reciprocal again.In use according to the different concrete condition of various near-sighted hypermetropias, the patient can independently set control oneself institute's observed articulation point far away of energy and nearly articulation point position, determine to observe treatment time, loosen the time of having a rest, timing automatic adjusting eyes are observed the position and the observing time of the outer far and near litura of far and near articulation point, this observation repeatedly clocklike, incremental periodicity ciliary muscle contraction is loosened adjusting and is taken exercise, the regulating power of eye is farthest recovered, myopia, hypermetropia and twenty-twenty vision are all had the good health care preventive and therapeutic effect.

As shown in Figure 2 hypermetropia myopia comprehensive physiotherapy appearance, its structure and Fig. 1 are basic identical, make up just that drive mechanism 2 drives ultra-short focus and zooming combined lens 4 simultaneously and observation image 5 moves, and its operation principle is also identical with Fig. 1, repeats no more in this.
