Description

A kind of visual training Medical Devices

Technical field

The invention belongs to sight protection technical field, more particularly, to a kind of visual training Medical Devices.

Background technology

Eyes are organs important in human sensory, but are continuously emerged with the continuous progress, electronic product etc. in epoch, Cause use of the people to eyes more and more heavier so that the degree of fatigue of eyes is constantly deepened, therefore protects eyesight to every It is all extremely important for individual.Occur a variety of vision training apparatus on existing market, but the visual training system of existing market All manually the disk of eyepiece is placed in rotation to system, and manually proofread to ensure that eyepiece aligns with eyepiece mouth, is not only imitated Rate is low, and both effects of alignment are also poor, influence using effect；Disk easily rotates in use simultaneously, Influence the normal use of device.

The content of the invention

The present invention is for overcome the deficiencies in the prior art, there is provided a kind of eyepiece accurate positioning, eyepiece eyesight easy to adjust Train Medical Devices.

To achieve these goals, the present invention uses following technical scheme：A kind of visual training Medical Devices, including it is outer Shell, the training screen in the shell, the eyepiece mouth on the housing and more changed the outfit with the eyepiece that the eyepiece mouth is engaged Put；The eyepiece more changing device includes base, the evenly spaced multiple eyepiece placed cavities being located on the base and located at institute State the eyepiece in eyepiece placed cavity；The base is rotatably arranged on the shell by an attachment structure, and the shell is also Provided with the positioner being engaged with the base.The present invention makes base rotate in place by the setting of positioner When, positioner can effectively be positioned to the position of base, ensure that eyepiece thereon aligns with eyepiece mouth, be eliminated pair The work that eyepiece chamber is proofreaded, improve operating efficiency, the comfort level that increase device uses；Meanwhile positioner and locating slot Cooperation can also effectively prevent base from being rotated during device use, device practical performance is stronger.

Further, the positioner include an evenly spaced circle locating slot in the base lower surface, The flexible positioning element being engaged with the locating slot, the shell are provided with the groove being engaged with the positioning element that stretches； When base rotation, flexible positioning element can receive extruding in retraction to groove, and groove is directed at when base is rotated to locating slot Position when, now eyepiece also can be just to turning the eyepiece mouth on shell；Because locating slot has certain depth, it is fixed now to stretch Part extended groove in position is simultaneously penetrated to locating slot, and the sound for sending " rattling away " informs user；Then user is in adjustment mesh During mirror, it is only necessary to the complete alignment of eyepiece and eyepiece mouth can be achieved in the base that stopped operating after the sound of " rattling away " is heard, without Carry out position check and correction operation.

Further, the flexible positioning element includes the elastic component and steel ball in the groove, the elastic component One end coordinates with the steel ball to be contradicted, and the other end coordinates with the groove bottom wall to be contradicted；The steel ball at least partly extend out to institute State groove；Steel ball smooth outer surface is set, and can be reduced its frictional force between base, be reduced abrasion between the two, is extended The service life of device；Steel ball can roll simultaneously, so that the rotation of base is more smoothly, without applying excessive work Firmly be turnable base, rapid operation.

Further, the pressure regulating part being engaged with the elastic component is additionally provided with the shell, the pressure is adjusted Adjustment seat that section part includes being downwardly extending by the groove bottom, the thread groove in the adjustment seat and it is arranged in institute State the screw in thread groove；The groove being engaged with the head of the screw is additionally provided with the adjustment seat, on the thread groove End is connected with the groove, and lower end connects with the groove；When long-term use of, the elastic force of elastic component can weaken, hence for Steel ball holds out against effect variation, and by the setting of pressure regulating part, the pressure condition that elastic component receives can be adjusted, with Increase elastic component for the pressure of steel ball, realize and base is fixedly positioning；By dazzle screw can aspect realize, operation letter Just；Pass through the setting of groove so that the head of screw will not extend out to adjustment seat lower surface, more aesthetically pleasing in profile.

Further, the attachment structure includes the connecting seat being fixedly arranged on the shell and is spirally connected with the connecting seat to match somebody with somebody The connector of conjunction, the connector middle part are downwardly extending a stud, and the connecting seat is provided with what is be engaged with the stud Thread cavity；The base is provided with the opening passed through for stud, and the connector end stretches out to form a circle rib, described Base is provided with the neck being engaged with the rib；When on base sheath to connecting seat, after the stud of connector is passed through into opening It is connected with thread cavity, due to the presence of rib so that base can not be deviate from from connector top, so that base is positioned in On shell；And base can rotate relative to connecting seat and connector so that base can opposite shell rotate, be conveniently adjusted base The eyepiece of upper diverse location is turned on eyepiece mouth.

Further, a locking member is provided between the connecting seat and the connector, the locking member includes being located at Lower thread groove on the connecting seat, the upper thread groove on the connector and the locking being arranged in the upper thread groove Bar, the securing rod are provided with external screw thread；The thread groove up and down is connected with the thread cavity respectively, and upper and lower thread groove Axis is on same straight line；Pass through the setting of the locking member so that connector remains during base rotation With the firm connection of connecting seat, will not deviate from respect to connecting seat；Turn securing rod so that the lower end of securing rod is penetrated to lower screw thread In groove, you can realize the firm connection of connector and connecting seat, even if producing frictional force during base rotation between connector, spiral shell Bar will not also screw out out of thread cavity, and locking effect is good, and simple in construction, is hardly damaged, and manufacturing cost is also low.

Further, the upper end of the securing rod is provided with a cross-shaped aperture groove, is easy to match somebody with somebody with criss-cross screwdriver Close securing rod described in turn.

Further, a power-assist part is provided between the base and the housing, the power-assist part includes being sheathed on Lower bearing outside the connecting seat and the upper bearing (metal) being arranged on the base；The lower bearing is provided with an anti-falling piece；Two axles The cooperation held make it that base is more smoothly relative to the rotation of shell, and the operation for adjusting eyepiece is more laborsaving.

Further, the anti-falling piece includes the external member that L-shaped is set, and the external member upper end stretches out to form a circle flange； The connecting seat upper end stretches out to form the stop edge that a circle is engaged with the flange, the lower bearing be provided with it is described The annular groove that external member is engaged；By stopping along the cooperation with flange, ensure that lower bearing will not be deviate from from connecting seat, in base not In the case of connection, lower bearing is not easy to be lost.

In summary, the present invention has advantages below：By the setting of positioner, base is set to rotate in place When, positioner can effectively be positioned to the position of base, ensure that eyepiece thereon aligns with eyepiece mouth, be eliminated pair The work that eyepiece chamber is proofreaded, improve operating efficiency, the comfort level that increase device uses.
