Background technology
At present, no matter school or unit learn generally to adopt horizontal table top with the desktop of desk.Because the height of desk is fixed, and desktop is horizontal level, so when reading or writing use, must bend over, bow, forward lean, lumbar vertebrae and cervical vertebra lean forward synchronously, eyes and books close together, not only block sight line easily, and study and work in this state for a long time, be easy to cause eyesight to descend, cause lumbar vertebrae or cervical spondylosis, even bring out hunchback, simultaneously since waist can not lean against on the chair back, the spinal nerves system long-term in tension cause neck, back, shoulder and waist tired easily, ache.
Summary of the invention
The utility model purpose is at the problems referred to above, in order to improve everybody study and work state, the prevention eyesight descends and produces bow-backed, eliminate because of long-time study and work produces fatigue and improves the study and work effect, provide a kind of plate face adjustable angle to put in order to the optimum position and the learning tool capable of preventing myopia of the most comfortable state.
The technical solution of the utility model is: learning tool capable of preventing myopia, comprise panel seat and study plate, described panel seat is provided with and is used for fixture that panel seat is fixed, described study can be controlled the lifting turning device of described study with plate lifting and upset with being provided with between plate and the described panel seat, be positioned at described study and be hinged with the reading plate, be provided with between described reading plate and the described panel seat and be used for control reading Board position supporting and positioning device with an end of plate reverses direction outer circumferential side.
Preferably, described lifting turning device comprises that described study is hinged respectively between the two ends, the left and right sides of reverses direction outer circumferential side one end and described panel seat with the backboard face and is connected to the end left and right sidesing post, described study is connected to the middle part left and right sidesing post with being hinged respectively between backboard face two ends, the left and right sides, middle part and the described panel seat, and described middle part left and right sidesing post length is less than described end left and right sidesing post.
Preferably, described reading plate supporting and positioning device comprises that described reading backboard face is hinged with reading plate support bar, and described panel seat is provided with and is used for determining and fixing the location tooth bar that described reading plate position of rotation is controlled in described reading plate support bar free end position.
Preferably, described study is provided with blend stop with the front away from described reading plate one end on the plate.
Preferably, described study is provided with study plate back-up block with the back side away from described reading plate one end on the plate.
Preferably, described reading plate is provided with reading plate back-up block away from the back side of hinged end, described back-up block is provided with fixedly inner chamber, chamber, described fixedly lumen openings place footpath less than fixing inner chamber inner chamber directly, described panel seat is provided with the corresponding fixed block that also can insert described fixedly inner chamber with described fixedly inner chamber, and the described fixed block direction of insertion extension in side upper edge of described back-up block week is provided with some slits that are connected and fixed inner chamber.
Preferably, described reading plate is provided with the long folder of elasticity away from the front of hinged end.
The learning tool capable of preventing myopia of technique scheme, it can be fixed by fixture, realize that by the lifting turning device plate level is used in study and the location is selected in two positions that tilt afterwards, and realize reading plate rotation location by supporting and positioning device, overcome the deficiency of existing level desktop, when plate is used in study at the obliquity state, it is very near apart from user's health, and formed certain angle of inclination, tilt adjustable, user's back can lean against the chair back, so just can come back, square one's shoulders, the study of straight waist, and be used to place reading class bookcases such as books by the reading plate, be convenient to the user more and adopt correct attitude to carry out study and work.So not only myopia prevention, hunchback in advance can also be loosened the in tension spinal nerves system of user, makes user's sitting and tired, and raising study and work effect avoids user's eyesight to descend.In the time will learning, can use as normal desk with plate and reading plate placement horizontal level state.The lifting turning device adopts to be hinged respectively between study is with two ends, the left and right sides, two ends, the left and right sides, middle part and the panel seat of backboard face outer circumferential side end and is connected to the four-bar linkage mode that left and right sidesing post constitutes, realize that plate level is used in study and the location is selected in two positions that tilt, simple and practical.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Fig. 1 is the structural representation when originally learning tool capable of preventing myopia is in the obliquity use;
Fig. 2 is that this learning tool capable of preventing myopia is horizontal the structural representation when using.
The specific embodiment
As depicted in figs. 1 and 2, learning tool capable of preventing myopia comprises panel seat 1 and study with plate 2, is provided with to be used for fixture 11 that panel seat is fixed on panel seat 1, as the mode that can adopt hold-down screw panel seat 1 is fixed on desktop 8 or other support.Study can be controlled the lifting turning device of study with plate 2 liftings and upset with being provided with between plate 2 and the panel seat 1, be positioned at an end of learning with plate 2 reverses direction outer circumferential sides and be hinged with reading plate 3, reading to be provided with between plate 3 and the panel seat 1 is used for control reading Board position supporting and positioning device.The lifting turning device can adopt be included in study with plate 2 back sides between the two ends, the left and right sides of reverses direction outer circumferential side one end and panel seat 1 respectively hinge be connected to end left and right sidesing post 6, be connected to middle part left and right sidesing post 5 in study with being hinged respectively between two ends, the left and right sides, plate 2 back sides middle parts and the panel seat 1, and middle part left and right sidesing post 5 length less than end left and right sidesing post 6 so that study with the horizontal positioned of plate 2 and the rear-inclined use of overturning.
